DETAILED DESCRIPTION

[0053] First, the apparatus according to an example embodiment will be described, and then the advantageous effects of the invention will be described.

[0054] FIG. 1 shows a schematic representation of the apparatus for connecting and monitoring processes of a production machine according to an exemplary embodiment.

[0055] The process monitoring device 10 has modular and/or universal sensor interfaces for the capture of highly dynamic signals such as forces, accelerations, acoustic signals, temperatures and/or pressures of the production machine 40, and an Ethernet interface and/or a modular fieldbus connector for data communication with the server device 30.

[0056] The connection device 20 optionally has an Ethernet interface and/or a modular fieldbus connector for data communication with the server device 30 or the production machine 40.

[0057] The server device 30 optionally has an Ethernet interface and/or a modular fieldbus connector for data communication with the connection device 20.

[0058] In the server device 30, incompletely processed data from different sources, which may be sensor data relating to the production machine, process data relating to the production machine of the process monitoring device, control data and connection data from the connection device 20 of the production machine, cloud/server data from other cloud/server devices, are brought together and correlated.

[0059] By merging incompletely processed data for data evaluation into a central system, such as server device 30, an increase in data quality and an increase in the information content of data can be achieved.

[0060] For the evaluation and correlation of data, in addition to the machine data, highly dynamic sensor data and data made available centrally by a cloud/server device can be used in parallel to determine complex relationships, parameters, trends, and the like. This means that no essential information can be lost and existing data can be used entirely to obtain information.

[0061] The server device 30 can change a hardware function of the apparatus using the relationships obtained; the apparatus may have a field-programmable logic gate array device which is designed to change a hardware function of the apparatus, and the server device 30 triggers the change in the hardware.

[0062] A field programmable logic gate array device embedded in the process monitor 10 constitutes a major component of the apparatus. All time-critical, computationally intensive and real-time significant functions are executed with this field-programmable logic gate array device. The field-programmable logic gate array device can be used to react to events during the processing process in a time-synchronous manner, wherein the demanding real-time requirements are met.

[0063] Adaptive control strategies to optimize cycle times, increase the service life of tools or to avoid phenomena that affect the quality of the workpieces such as chatter, grinding burn, or the formation of corrugations extending round the periphery, are just a few examples of the necessary reactions that must be carried out in real time.

[0064] The parallel reading and visualization of highly dynamic sensor signals and the data processing thereof, such as pre-filtering, is also implemented in the field-programmable logic gate array device. This means that several applications can be run simultaneously without violating the hard real-time requirements. At the same time, digital input and output signals are managed by the field programmable logic gate array device.

[0065] The visualization does not take place in the FPGA, but alternatively on the local web server or central web servers.

[0066] The apparatus can be expanded in a modular manner using the available Ethernet interface and/or the available modular fieldbus connector, which are designed for data communication with other apparatuses for connecting and for monitoring processes of a production machine.

[0067] The embedded field-programmable logic gate array facility in the apparatus allows the apparatus to be used easily and flexibly for other applications without having to convert hardware. Thus, the apparatus for connecting and for monitoring processes of a production machine is ideally suited to be used in prototype construction as well as in the mass market.

[0068] The integration of a process monitoring device, a connection device and a server device in one apparatus increases IT security against hacker attacks from outside the network, since the integrated systems can be ideally coordinated with one another and communication between the integrated systems is thus better protected.

[0069] In addition, simplified handling for the user is achieved since only one device must be configured.

[0070] In other words, the apparatus for connecting and for monitoring processes of a production machine is designed to provide a combination of a process monitoring system with a connection system.

[0071] The apparatus for connecting and for monitoring processes of a production machine is also designed to provide use of FPGA technology, which enables hardware functions to be changed flexibly.

[0072] The apparatus for connecting and for monitoring processes of a production machine is also designed to enable the inclusion of machines, sensor, and server/cloud data for local evaluation of the same for the purposes of process regulation, control, and visualization, and this also synchronously.

[0073] The apparatus for connecting and for monitoring processes of a production machine is also designed to carry out a flexible and needs-based reconfiguration of hardware, can be triggered by a central system (server/cloud), and can also be based on requirements determined in the central system or triggered manually.

[0074] FIG. 2 shows a flow chart to illustrate steps of a method for connecting and monitoring processes of a production machine according to an exemplary embodiment.

[0075] In a first step, a capture S1 of the sensor data relating to the production machine 40 and process data relating to the production machine 40 takes place by means of a process monitoring device 10.

[0076] In a second step, a capture S2 of the control data relating to the production machine 40 take place by means of a connection device 20.

[0077] In a third step, a processing S3 of the captured sensor data, process data, and connection data takes place by means of an apparatus.

[0078] In a fourth step, a change S4 of a hardware function of the apparatus takes place on the basis of the sensor data, the process data, and the connection data.

[0079] FIG. 3 shows a process diagram to illustrate steps of a method for connecting and monitoring processes of a production machine according to an exemplary embodiment.

[0080] The numbered arrows in the example are in ascending chronological order.

[0081] 1. Capture of all machine data (sensor data, process data, control data, machine data).

[0082] 2.1 Pre-filtering, analysis of data and, if necessary, initiation of a reaction to the machine.

[0083] 2.2 Transmission of significant information about the connection device to the cloud.

[0084] 3. Data from multiple devices is sent to the cloud. There, analyses and correlations are carried out with available information/data.

[0085] 4. If necessary, initiation of a change of the system's hardware function triggered by the cloud.

[0086] However, the present disclosure is not limited to the exemplary embodiment.
