(26) Various embodiments may incorporate one or more of these and other features described herein while remaining within the spirit and scope of the invention. Further features of the present invention, its nature, and various advantages and embodiments will be more apparent by reference to the accompanying drawings and the following detailed description of the exemplary embodiments of the present invention.

DETAILED DESCRIPTION OF EMBODIMENTS

(27) In the following description, numerous specific details are set forth, such as examples of specific data signals, named components, connections, number of memory columns in a group of memory columns, and the like, in order to provide a thorough understanding of the present invention. It will be apparent, however, to one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well known components or methods have not been described in detail but rather in a block diagram in order to avoid unnecessarily obscuring the present invention. Further specific numeric references such as “first driver,” may be made. However, the specific numeric reference should not be interpreted as a literal sequential order but rather interpreted that the “first driver” is different than a “second driver.” Thus, the specific details set forth are merely exemplary. The specific details may be varied from and still be contemplated to be within the spirit and scope of the present invention. The term “coupled” is defined as meaning connected either directly to the component or indirectly to the component through another component.

(28) In general, a system and method are provided which enables a user to connect a serial port of a device server to a serial port of a serial device, query and capture data and settings pertaining to the serial device such that the device server can communicate and exchange data with the serial device without requiring customized programming. The device server may periodically query and capture user-specified data from the serial device. A poll configuration feature may be used to specify one or more commands which the device server will periodically query from the serial device. The response to each poll may be further sliced into a multiplicity of fields according to user-specified filter rules. The captured data may be presented to other users online by way of a Web Manager, and the device server may establish machine-to-machine communications by way of XML and a Command Line Interface.

(29) FIG. 1 illustrates an exemplary embodiment depicting the connection of a device server 10 to a serial device 15. The device server includes, but is not limited to, a processor 20 and a memory 25 which is in operable communication with the processor 20. The device server 10 also includes a serial port 30 and an Ethernet port 35. The device server also includes a communication interface (not shown), which couples the processor to the serial port 30 and Ethernet port 25.

(30) The processor 20 is configured and controlled using programming consisting of various software commands which may be stored in memory 25. The processor operates in accordance with software commands to carry out the functions of a server to facilitate communications between the device server and the serial device 15. The programming may be written in any suitable programming language that is capable of being run by the processor, in compiled form in some instances, and in as written form in other instances, such as when providing network services based on hypertext markup language.

(31) Throughout the description reference will be made to various software programs and hardware components that provide and carryout the features and functions of the various embodiments of the present invention. Software programs may be embedded onto a machine-readable medium. A machine-readable medium includes any mechanism that provides, stores or transmits information in a form readable by a machine, such as, for example, a computer, server or other such device. For example, a machine-readable medium includes read only memory (ROM); random access memory (RAM); magnetic disk storage media; optical storage media; flash memory devices; digital video disc (DVD); EPROMs; EEPROMs; flash memory; magnetic or optical cards; or any type of media suitable for storing electronic instructions.

(32) Some portions of the detailed descriptions are presented in terms of algorithms and symbolic representations of operations on data bits within a computer memory. These algorithmic descriptions and representations are the means used by those skilled in the data processing arts to most effectively convey the substance of their work to others skilled in the art. An algorithm is here, and generally, conceived to be a self-consistent sequence of steps leading to a desired result. The steps are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like. These algorithms may be written in a number of different software programming languages. Also, an algorithm may be implemented with lines of code in software, configured logic gates in software, or a combination of both.

(33) It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the above discussions, it is appreciated that throughout the description, discussions utilizing terms such as “processing” or “computing” or “calculating” or “determining” or “displaying” or the like, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers, or other such information storage, transmission or display devices.

(34) In an embodiment, the logic consists of electronic circuits that follow the rules of Boolean Logic, software that contain patterns of instructions, or any combination of both.

(35) Referring again to FIG. 1, device server 20 communicates with serial device 15 over serial connection 40, which may be a serial cable capable of carrying signals confirming to the RS232 standard between the device server and the serial device. Serial connection 40 connects serial port 30 of the device server to serial port 45 of the serial device.

(36) Device server 20 also includes Ethernet port 35, which facilitates connection to a wired Ethernet based network. Alternatively, device server may also include a wireless transmitter/receiver 50 which is configured to be controlled by the processor 20 to send and receive information through antenna 45 through a wireless network.

(37) FIG. 2 depicts one embodiment illustrating a network enabled control system 60 for communicating with a serial device 75. In this embodiment, device server 70 is coupled through network/cloud 65 to a user 80. Device server 70 is also coupled by communication line 85 to serial device 75 through the serial ports of both devices. As discussed above, device server 70 may be coupled wirelessly, or through a wired network, such as an Ethernet network, or the Internet to user 80. User 80 will typically be a computer having a processor, input/output device such as a keyboard, mouse or other input means, and a display, memory and communication interface.

(38) It will be understood by those skilled in the art that the network/cloud may comprise one or more servers, databases, and associated memory or other storage facilities, as well as appropriate communication circuitry and interfaces to facilitate information flow between the user and device server. Various software programs may also be run on the User's processor, the device server, and any or all of the servers comprising the network to allow for bidirectional communication of information through the network.

(39) For example, device server 70 may include software that provides a graphic user interface (GUI), or a command line architecture, that can be accessed by a user to communicate with, configure, and control the processor of the server. One such program may be program such as a Monitor Explorer, one screen of which is illustrated in FIG. 3. Using such a program as Monitor Explorer to provide a GUI allows for configuration and use of the device server 70 by a user to capture data from serial device 75 without requiring specialized programming. Moreover, since the device server 70 is network enabled, the user may configure, operate, and capture data from serial device 75 remotely, that is, from a location that is remote from either device server 70, serial device 75, or both.

(40) Monitor Explorer is an embodiment of a software program that is stored in the memory 25 of device server 10 (FIG. 1). Alternatively, the Monitor Explorer program may be firmware embedded in the processor. In either case the Monitor Explorer program provides an interface between the device server and the user so that the user can explore the communication requirements and settings of the serial device through the device server, and then configure the device server to transmit and receive information and data from the serial device which can then be transmitted through the network to the user, or to some other entity that wishes to receive the information and/or data from the serial device.

(41) The Monitor Explorer program may also be accessed through a program such as a web manager program that is stored in the memory of the device server. A user, upon connecting to the device server, may log into the web manager, and, upon validation of the user's right to access the device server, may be presented with various programs or sub-programs that may be called using in the web manager.

(42) Typically, device server 70 will not be directly coupled to a display or user input/output devices. Accordingly, the processor of device server 70 is accessed by a user indirectly, through a network connection. Accordingly, the examples and description below may be assumed to contemplate that a person using the GUI described below has already logged into the device server.

(43) When an external serial device is initially connected to the device server 70, the initial state of the external serial device is unknown to the device server. Accordingly, a screen such as that depicted in FIG. 3 is presented to the user, indicating that the status of the serial device is unknown.

(44) FIG. 3 depicts one embodiment of a software program, hereinafter identified for exemplary purposes only as a web manager 100, that provides various functions for monitoring and controlling a device controller to which is connected a serial device. Web manager 100 includes a column 105 in which are displayed various tabs, each tab associated with a particular function of the web manager program. For example, column 105 includes a “monitor” tab 110.

(45) As shown in FIG. 3, the display also includes a central portion 107, which includes various soft keys or buttons (tabs or hot spots that can be activated using a touch screen, or which can be accessed using traditional pointing techniques, such as arrow keys or a mouse) such as a “Status” button 115, an “Explore” button 120, and a “Configuration” button 125. As will be discussed in greater detail below, activating one of the buttons results in a sub-program call that displays various screens associated with the particular button activated. These displays are configured to display information, allow for input of commands and parameter values, or both. Other soft keys or buttons may be incorporated into various areas of the central portion 107 to facilitate selection of a particular function or feature of the software program.

(46) The central portion 107 also includes areas that are designated for the display of information or data that is communicated to the user. Under certain circumstances, the program may display information to the user, and also provide an area for the user to enter a command or response. Column 108 typically provides information to the user to assist the user in interpreting and/or responding to data, information, or command requests presented by the program in central portion 107.

(47) Upon connecting the serial device to the device server, a user may select Monitor from the tabs of column 105 to determine the status of the serial device. At this time, the user may select the “Explore” button 120 to “explore” the serial device to determine the serial device's initial state.

(48) Alternatively, the user may access an alternative embodiment, shown in FIG. 4, by selecting “SPI” tab 150 from column 105. Activating this tab displays the screen shown in FIG. 4 using a Serial Peripheral Interface (SPI) bus when the device driver is connected to an external slave device. The initial state of the slave device is displayed in an SPI Configuration screen. Entries made using this screen take effect immediately.

(49) In one embodiment, the “Explore” feature of the Monitor program provides a sequence of five display pages to the user that may be used to determine the proper settings to communicate with the serial device as well as make entries to configure the device server to communicate with the serial device. The “Configuration” button 125 may also be activated from any of the displayed pages to go directly to an applicable configuration page and make specific changes. The device monitoring status may also be viewed by activating the “Status” button 115.

(50) The screens that are displayed to the user may be used to determine the output provided by the serial device and also to allow the user to create data parsing rules for selecting specific data from the stream of data produced by the serial device. All of this may be accomplished in real time without the need for the user to write complicated programming, and the results of the user entries may be tested in real time to determine if the entered rules and other parameters provide the desired data. Once the rules and parameters are entered, they may be stored in the memory of the device driver, and then are used by the processor of the device driver to interpret and parse the incoming stream of data from the serial device to provide data desired by the user to be transmitted through the Ethernet port of the device server to the user over a network or the Internet.

(51) In one embodiment, the five pages presented to the user when accessing the “Explorer” program include; a setup initiation page; a setup commands page; a define filters page; a pick data page; and a confirm and submit changes page.

(52) FIG. 5 illustrates one embodiment of a screen presenting the setup initialization page screen f the Monitor Explorer program. As shown, the setup initialization page may be used to send one or more messages to the serial device so as to bring the serial device into a known state. For example, a Message 160 may be created that is sent to the serial device to determine the device's status. Message 160, in this embodiment, comprises four fields which are accessed by activating the “Edit” button or soft key 165 for that message. The fields of the string that comprises Message 1 (and all the messages shown in FIG. 5), are, in order: command, entered in binary format, such as for example [0x0d] for a carriage return or enter key command; end character; length of the response; and timeout, which is the minimum time the device server will wait for a response. Once these parameters are entered by the user, the user activates the “Submit” button or soft key 170.

(53) FIG. 6 illustrates the response from the serial device when the submit button 170 is activated. As shown, four messages submitted resulted in responses from the serial device that are shown in area 180.

(54) Once the initial setup is completed, the “Next” button 175 is activated which changes the display screen to the setup commands page shown in FIG. 7. Using this page, the user can modify each of the messages transmitted by the device server to the serial device. Further, the data displayed for each Message pertain to the poll settings for the device. A poll refers to how often the device server will send a message to the serial device.

(55) For example, to modify Message 1, the user activates “Edit” button 190, which expands the screen display as depicted in FIG. 8 to show the values for each of the fields that comprise the string of Message 1. This page provides the user with entry fields for each of the fields comprising the string of parameters which makes up Message 1. The expanded display can be compressed by activating the “hide” button 200.

(56) As shown, the values for the command, end character, length and timeout fields can be modified. As described above, each time the device server transmits (or polls) the message to the serial device, the command identified in the command field sent to the device should evoke a response from the serial device. The character end field identifies a character that the device server looks for that identifies the end of a response from the serial device to the transmitted command. The length field sets the maximum length of the response, and the timeout field sets the length of time the device server will wait for a response from the serial device. Each of the configuration parameters may be modified on this page.

(57) Alternatively, the user may activates the Monitor “Configuration” button 125 to directly modify one or more poll settings. This alters the display to that illustrated in FIG. 9. Use of this page allows the user to change the settings of each message so as to optimize communication with the serial device until acceptable initiation settings are determined.

(58) In an embodiment, illustrated in FIG. 10, the Monitor Explorer program may be used to test the commands selected in the Monitor Poll Configuration feature, enabling the user to view an immediate response from the serial device. For example, as shown in area 180, Message 1 was altered from exit[0x0d], with a timeout of 500 milliseconds to show[0x0d], with a timeout of 200 milliseconds. The Display field 130 was altered to display the result of Message 1, the results of which are shown directly below in area 135.

(59) In an exemplary embodiment, the response to each poll may be sliced into smaller portions according to user-specified filter rules. Slicing the data advantageously facilitates later access to the desired data, without having to search through large quantities of unneeded data. In one embodiment, the user may examine the form of the response received from a particular poll, looking for clues in the response to locate desired information. The user may further determine whether the form of the response may include variations depending on the state of the serial device.

(60) The rules for slicing the poll responses are configured by accessing the Define filter page, as illustrated in FIG. 11. In this embodiment, the user may utilize Monitor Explorer, or may directly configure the rule settings in a Monitor Filter Configuration feature. The response from the poll is shown in area 195. The user typically analyzes this response to determine what data the user is interested in.

(61) For example, the user may be interested in the value for the “Uptime” parameter, identified by reference numeral 205. As shown in FIG. 11 using the Monitor Explorer program, Rule 1 has no definition parameters. Rule 1 can be modified from this screen by activating the “Edit” button 200 to focus in on the “Uptime” parameter.

(62) As will be apparent, many different rules may be established to parse the data and information provided by the serial device to the poll of the device server. Rules are generally performed sequentially, but each rule can point to either raw source (0) or a result of a previous rule (R.f). In one embodiment, each rule may slice the raw input from the serial device into multiple fields (f). Thus, the nomenclature R.f refers to a particular sliced result selected from the rule.

(63) FIG. 12 illustrates setting up an exemplary series of rules to identify and slice the response contained in area 195 of FIG. 11 into usable information. In this example, Rule 1 is comprised of a series of parameters that are used to point to the first carriage return indicating the beginning of a field of data as transmitted by the serial device. A rule is configured sung as many as six parameters, but may also be configured using less than six parameters, depending on the mode configuration selected.

(64) The first of the six rule configuration parameters is source, which indicates the input of the filter or rule. In the example shown in FIG. 12, Rule 1 has a source of 0, which indicates that the input of Rule 1 is the raw response received by the device server from the serial device when it was polled. Rule 2, in contrast, has a source parameter of 1.6, indicating that, in R.f notation, it filters for information contained in the sixth field of the output of Rule 1.

(65) The second rule configuration parameter sets the mode of the rule. In one embodiment, the possible values include: all, delimiters, or binary.

(66) The third mode configuration parameter defines one or more delimiters that are applied with the rule, but is only displayed if delimiter mode is selected when entering the mode parameter, as described above. The number of delimiters to be applied is identified, as well as a binary string that is used to separate each delimited portion of the response. Delimiters are not included in a trunk of data. As shown in the display of the parameters for Rule 1, delimiter mode is selected, and the binary string separating information trunks is [0x0d, 0x0a].

(67) The fourth rule configuration parameter identifies a start index to indicate when delimiters start breaking input into trunks, if delimiter mode is selected.

(68) The fifth rule configuration parameter, is an offset parameter, which is used to set the size of the first trunk of data if binary mode is selected.

(69) A sixth rule configuration parameter is a length parameter, which, when the binary mode is selected, specifies the size of a second trunk of data created by the binary filter, if the binary mode is selected. In this mode, a third trunk of data created by the binary filter will contain the remainder of the raw input.

(70) Using the parameters defined above, Rules 1 and 2 are applied to the raw input displayed in area 195 of FIG. 11 are displayed in the response area 210 of FIG. 12. In this example, as indicated above, Rules 1 and 2 are configured to find the value for “Uptime” that is contained in the output of the serial device. Applying the rules to the output of the serial device yields a value for “Uptime” as 8 days 00:08.30. As shown, the display has been set to display the response as filtered by Rule 2.

(71) FIG. 13 illustrates an exemplary alternative embodiment whereby the Configuration feature of the Monitor Explorer is utilized to set the filter parameters for various rules that will be applied to the data stream received from the serial device. This example illustrates how the filters can be defined using the binary mode, using user selected offset and length parameters.

(72) Once the user has created one or more filters, the user may select the particular data to be mined, so as to present the data to other users or to one or more machines on the network. In an exemplary embodiment, the user may have created multiple polls and filters, and different filters may generally apply to each of the multiple polls, though some filters may be applicable to more than one poll. However, since all of the slicing of the raw data is virtual, and thus all of the filter rules overlay raw data from each response to a poll, the user need only be concerned with the rules pertaining to a particular poll message.

(73) Once the rules and polling frequency for analyzing the data stream received from the serial device have been established, the user may then configure the device driver using the Monitor Explorer program to select specific data from the data stream to be displayed or transmitted to the user. In an exemplary embodiment, illustrated in FIGS. 14-15, the user may utilize Monitor Explorer or directly configure settings in a Monitor Data Configuration feature, as depicted in FIG. 16, to specify the data from the output of the Rules that have been applied that is desired for further display or analysis.

(74) In Monitor Explorer, clicking the “Next” button on the “Define filters” page takes the user to the “Pick data” page, shown in FIG. 14. When the pick data page is displayed, two fields are displayed in area 250 identifying one or more “Selectors” that are used to identify the data that will be selected to be transmitted to the user or another piece of equipment that will use the data, or report the data. The first field identifies the particular selector, and the second field identifies the parameters of the Selector.

(75) Multiple Selectors can be defined to select multiple data items from the results of the applications of the one or more rules previously defined and applied to the raw data received from the serial device by the device server. Activating the “Edit” button 255 associated with a particular Selector causes the display of the screen depicted in the FIG. 15, which provides for modifying the parameters of each Selector.

(76) In an embodiment, illustrated in FIG. 15, each Selector has a Selector Name, a Response, and a Reference. The Selector Name is presented as a caption for the data associated with the Selector. The Response is a poll message number. The Reference is a rule number, dot, and a field number (R.f), which specifies the data field associated with the Selector.

(77) Alternatively, the one or more Selectors (if any) may be configured using the “Configuration” program that is accessed by activating the “Configuration” button 125, as depicted in FIG. 16. When the “Data” button 300 is then activated, the data configuration screen is shown, which is similar in function to that described with reference to FIG. 15.

(78) Once the user has configured the desired Selectors, the user may select the Confirm and submit changes screen of the Monitor Explorer as illustrated in FIG. 17 to review the parameters for the messages, rules and selectors set by the user to mine data from the raw input received by the device server from the serial device. As shown, each parameter may be further altered by activating the appropriate “Edit” button. When the user is satisfied with the configuration, the user may activate the “Submit” button to permanently change the configuration stored in the memory of the device server, the results of which are presented to the user as depicted in FIG. 18.

(79) In an exemplary embodiment, the user may consider options for sharing the data that was mined utilizing the various embodiments described above. In an embodiment, a Web page may be used for presenting the data to other users. In another embodiment, XML may be used to present the data for machine-to-machine communications. In still another embodiment, a Command Line Interface may be used for both machine-to-machine communications and other users.

(80) In an embodiment illustrated in FIG. 19, the mined data is automatically presented upon utilizing the Monitor Status feature in the Web Manager. In another embodiment, illustrated in FIG. 20, the data may be automatically displayed by way of a Command Line Interface. In still another embodiment, illustrated in FIG. 21, the mined data may be automatically displayed using XML programming code.

(81) In an exemplary embodiment, data received from a serial device may be presented to a user through the Web Manager software running on the processor of the device server. Typically, however, the data that results from application of the various Messages, Rules and Selectors of the various embodiments described above needs to be formatted in a manner that allows the data to be presented or transmitted in a useful manner.

(82) For example, in the case where a Serial Peripheral Interface port of the device server is connected to an external SPI slave device, the data may be communicated to the device server in a binary format, which is processed as described above. The binary form of data from the SPI must be converted to an appropriate format before being presented. In an embodiment, the binary data may be converted by using HTML and/or JavaScript programs that are loaded into and run by the processor of the device server.

(83) FIG. 22 illustrates one embodiment of a compressed JavaScript chart library (i.e., dygraph.combined.js.gz) and a customized device home page (i.e., index.html) that may be selected and run by a user of a File System Browser feature of the Web Manager to display desired data that has been extracted from the raw data stream received by the device server from the serial device using the various embodiment described above. FIG. 23 illustrates one embodiment of the customized JavaScript chart library presented on the customized device home page, illustrating process and room temperature as a function of time, as measured by one or more serial temperature sensing devices that are monitored by a device server using the systems and methods of the various embodiments of the present invention described above. Those skilled in the art will appreciate that other software programs or languages may be used to convert the processed data from the device server into a useable form without departing from the contemplated scope of the invention.

(84) While the user interface of the present invention has be described with reference to a graphical user interface, as shown in the drawings, the device server configuration settings may be explored and/or altered using alternative interface designs and methods.
