DETAILED DESCRIPTION

[0082] FIG. 1 shows a possible embodiment of a prior art radio sensor FS.

[0083] The radio sensor FS comprises an integrated antenna A coupled to a radio board FP and a sensor S to which a sensor board SP is assigned. The antenna A is here integrated in a housing cap KG as a component.

[0084] The sensor board SP can transmit sensor data via the antenna A and takes electrical energy for this purpose from a single-cell energy storage device ES, for example an accumulator or a battery. In addition to transmission, the sensor board SP is designed for evaluation and processing of sensor data acquired by the sensor S.

[0085] FIG. 2 shows another possible embodiment of a prior art radio sensor FS.

[0086] In contrast to the example shown in FIG. 1, the antenna A is mounted on the outside of the housing cap KG.

[0087] FIG. 3A shows a sectional view of a possible embodiment of a radio sensor module FSM according to the invention.

[0088] The radio sensor module FSM comprises an upper sensor module OSM and a lower sensor module USM coupled to it.

[0089] In the illustrated embodiment example, a sensor S designed as a pressure or temperature sensor is assigned to a sensor board SP, both of which are arranged in the lower sensor module USM.

[0090] The sensor board SP is connected to a radio board FP via an EMC board EMV and forms an interface between the upper sensor module OSM and the lower sensor module USM.

[0091] In the upper sensor module OSM, an antenna A designed as a radio antenna is arranged “onboard” on the radio board FP.

[0092] As shown in more detail in FIG. 4A, the radio board FP and the sensor board SP are coupled to an energy storage device ES for the power supply, the energy storage device ES comprising a battery BA in the form of an accumulator and a capacitor K. A housing cap KG sealingly encloses the energy storage device ES and the radio board FP, i.e. at least essentially the upper sensor module OSM.

[0093] FIG. 3B shows a further sectional view of the radio sensor module FSM in a plane SA according to FIG. 3A, which illustrates an arrangement of the battery BA and the capacitor K in position to the radio board FP.

[0094] Both the battery BA and the capacitor K are accommodated within the upper sensor module OSM in a radio sensor unit and are held in a predetermined orientation relative to each other by a structure carrier TT or carrier part shown in more detail in FIG. 4A. The structural carrier TT is designed to accommodate one or different radio boards FP, i.e. radio printed circuit boards.

[0095] To form a compact arrangement, an axis G1 of a circuit board plane of the radio circuit board FP is interleaved with an axis G2 of a middle plane of the combined energy storage device ES, formed of battery BA and capacitor K, and at an intersection SCP of the two planes, these have in particular an angle a of 5° to 35° or 10° to 60° with respect to one another.

[0096] In particular, the battery BA and the capacitor K are electrically connected in parallel with one another. By designing the internal arrangement shown, different circuit board geometries and different battery types can be combined with each other, as described in more detail in the following embodiments.

[0097] FIG. 4A shows a sectional view of a further possible embodiment of a radio sensor module FSM according to the invention, in particular a more detailed principle view of the radio sensor module FSM according to FIGS. 3A and 3B.

[0098] Here, the radio sensor unit is arranged as an upper sensor module OSM on the lower sensor module USM.

[0099] Here, too, the sensor S is coupled and arranged in the lower sensor module USM with the sensor board SP for evaluation and amplification of the sensor data.

[0100] The sensor S is enclosed by the receiver base part AUT, which accommodates the sensor S and the sensor board SP, in particular in a sealed manner. The receiver base part AUT establishes a connection to the lower process port PA, to which a thread is formed.

[0101] Furthermore, the receiver base part AUT provides device connection surfaces GA on its outer side, at which a user can couple the receiver base part AUT to a process by a tool and, in particular, fasten it in a sealing manner.

[0102] For example, the receiver base part AUT is trough-shaped and comprises the process port PA, as shown in the embodiment. The process port PA is welded or formed onto the transducer lower part AUT. In embodiments not shown in more detail, the process port is not a component of the transducer lower part AUT.

[0103] The upper sensor module OSM comprises a structure carrier TT or a carrier part, which accommodates the energy storage device comprising the battery BA and the capacitor K as well as the radio board FP with the integrated antenna A.

[0104] The battery BA and the capacitor K are coupled to the radio board FP via a connector SV1 and supply electrical energy to all boards of the upper sensor module OSM on demand.

[0105] A spring element FE fixes the battery BA and the capacitor K via an elastic preload in the structure carrier TT and dampens externally acting vibrations for the energy storage ES.

[0106] The radio board FP has the antenna A, which is designed as an integrated conductor track or as an “onboard” mounted component.

[0107] The radio board FP is coupled to the EMC board EMV via a second connector SV2, which forms an interface between the upper sensor module OSM and the lower sensor module USM.

[0108] The EMC board EMV is coupled to the sensor board SP via another connector SV3. The electrical connector SV3 transmits both sensor data and power, but is also designed with several pin contacts so that other lower sensor modules USM can be coupled.

[0109] In particular, this connector SV3 is designed in such a way that a universal radio transmission connection UFSV can be provided at this point.

[0110] An interface generated in this way is also characterized in particular by the fact that sensors S or sensor boards SP connected at this point are briefly switched on in time windows for individual polling of measured values. This can be done, for example, on request and control of the radio board FP by switching on an electric current via MOSFETs or via a start value. Hereby, a switching on and off of the lower sensor module USM can be realized according to predetermined times or clockings, which have been defined in a software or a memory or configured by a user, in particular by radio control via a mobile communication device.

[0111] This can be done, for example, via the Bluetooth radio standard by app, or it can also be done by remote access via another radio protocol, such as a so-called MIOTY or LORAWAN protocol. In this case, for example, an integrated light, such as a light-emitting diode LED, on the FP radio board provides the user with a current status. The light is visible, for example, via an opening OE in the housing cap KG.

[0112] The housing cap KG is guided to the structure carrier TT via a bayonet lock BJ and can thus be removed without tools. Furthermore, the housing cap KG has a stop AS on the inside for axial guidance and limitation of the energy storage device ES, whereby the stop AS can also be designed as a molded-on step on a plastic part.

[0113] The housing cap KG also seals via an O-ring OR to a centering intermediate ring ZR, which accommodates the EMC board EMV in a sealing manner and is attached in a sealing manner circumferentially to the receiver base part AUT by a welded joint SW.

[0114] FIG. 4B shows another sectional view of the radio sensor module FSM, which illustrates the arrangement of the energy storage device ES in the structure carrier TT.

[0115] Essentially shown here is the structure carrier TT, which accommodates the battery BA, the capacitor K and the radio board FP. Both the battery BA and the radio board FP are exchangeably guided by molded-on guide ribs AN in the housing cap KG.

[0116] As shown in FIG. 3B, the axes G1, G2 of the printed circuit board plane of the radio board FP are interleaved with the middle plane of the combined energy storage device ES, formed of battery BA and capacitor K, for a more compact arrangement, and the intersection point SCP between the two planes or axes G1, G2 of the planes has, in particular, an angle α a [sic—delete a?] of 5° to 35° or 10° to 60°.

[0117] The intersection point SCP between the two planes lies in particular outside the housing cap KG. The battery BA and the capacitor K are connected in particular via an integrated circuit which automatically disconnects them from the radio board FP in the event of overtemperature or overload.

[0118] FIG. 5 shows a sectional view of another possible embodiment of a radio sensor module FSM according to the invention.

[0119] Here, too, the intermediate ring ZR accommodates the EMC board EMV as an interface between the lower sensor module USM and the upper sensor module OSM, the intermediate ring ZR being optionally permanently connected to the structure carrier TT or the receiver base part AUT.

[0120] The housing cap GK can be removed after rotation in direction (1). Hereafter, the radio board FP can be removed or exchanged from shafts of the structure carrier TT in direction (2) or a short energy storage ES-K can be removed or exchanged from shafts of the structure carrier TT in direction (3), i.e. vertically upwards. In this way, both a change of an energy storage device ES-K and a change of a radio board FP are possible.

[0121] Since different radio boards FP are possible, a radio standard or a transmission type can also be easily changed in this way. This is supported in particular by the vertical design of the second connector SV2, which is arranged on the EMC board EMV.

[0122] Here, too, the spring element FE fixes and/or supports the energy storage device ES in a vibration-damped manner inside the upper sensor module OSM, regardless of its length.

[0123] Dotted lines show a different equipment with a larger, i.e., in particular longer, energy storage device ES-L. Likewise, the use of a longer radio board FP with an antenna A is dashed and indicated as an option.

[0124] Depending on the design of the energy storage ES, ES K, ES-L, different housing caps GK can be mounted, which are characterized in particular by a different length, which differ in different heights in the direction of extension of the radio sensor module FSM, i.e., for example opposite to the process port PA.

[0125] In all other respects, the structure of the illustrated radio sensor module FSM corresponds in particular to the embodiment illustrated in FIGS. 4A and 4B.

[0126] FIG. 6A shows a perspective view of another possible embodiment of a partially disassembled radio sensor module FSM according to the invention in a first configuration, i.e., in particular in a first equipment variant.

[0127] In this case, the structure carrier TT is equipped with a short, small energy storage device ES-K, which protrudes from the structure carrier TT with a headroom B1.

[0128] The radio board FP is arranged in a short version with a height FP1 protruding above the structure carrier TT, whereby the connector SV1 is oriented at a height (X) in the upper sensor module OSM to the structure carrier TT or to the intermediate ring ZR.

[0129] A bayonet path BJB is formed on the structure carrier TT, in which a knob BN of the housing cap KG engages when it is put on and can be locked by turning.

[0130] In all other respects, the structure of the illustrated radio sensor module FSM corresponds in particular to the embodiment illustrated in FIGS. 4A and 4B.

[0131] FIG. 6B shows a perspective view of a further possible embodiment of a partially dismantled radio sensor module FSM according to the invention in a second configuration, i.e., in particular in a second equipment variant.

[0132] Here, the structure carrier TT is equipped with a larger, long energy storage device ES-L, which protrudes from the structure carrier TT with a headroom B2. The headroom B2 is greater than the headroom B1 of the example of the radio sensor module FSM shown in FIG. 6A.

[0133] In a longer version, the radio board FP is designed with a height FP2 protruding above the structure carrier TT, whereby the connector SV1 is also oriented here as in the embodiment example shown in FIG. 6A at the same height (X) in the upper sensor module OSM to the structure carrier TT or to the intermediate ring ZR.

[0134] In all configurations, the connector SV1 to the energy storage ES, ES-K, ES-L is thus oriented in particular at the same height (X) to enable all combinations without cable extensions or cable shortening.

[0135] In all other respects, the structure of the radio sensor module FSM shown corresponds in particular to the embodiment example shown in FIGS. 4A and 4B.

[0136] FIG. 7 shows an exploded view of a possible further embodiment of a radio sensor module FSM according to the invention with differently designed lower sensor modules USM in section as a platform view with possible couplings.

[0137] The upper sensor module OSM comprises the housing cap KG, which accommodates the radio board FP and the energy storage device ES.

[0138] The EMC board EMV is coupled to this via a universal radio transmission connection UFSV2 and is mounted in a sealing manner in the intermediate ring ZR. The intermediate ring ZR also seals off toward the housing cap KG.

[0139] As a termination of the upper sensor module OSM, the EMC board EMV has a universal radio transmission link UFSV3, via which several different lower sensor modules USM1, USM2, USM3 can be coupled and operated.

[0140] This includes, for example, the lower sensor module USM1 already shown in FIG. 5 with integrated sensor S, which is coupled to a process port PA and is arranged with an associated sensor board SP in the receiver base part AUT.

[0141] However, it is also possible to arrange another lower sensor module USM2 with a board PL2 in a receiver base part AUT2, wherein instead of a process port PA downward a connector SV4 is coupled to the board PL2. The connector SV4 provides an interface through which a conventional sensor S2 can be connected via a cable KA.

[0142] Here, the sensor S2 can be designed as a pressure sensor or other sensor, which is operable according to the 4 mA to 20 mA standard or the so-called HART or Profibus standard. Also, the sensor S2 can be addressable via another sensor protocol. Furthermore, the sensor S2 can be addressed via an interrupt or sequentially addressed and switched on via a MOSFET.

[0143] It is also possible to arrange another lower sensor module USM3 with a board PL3 in a receiver base part AUT3 on the upper sensor module OSM, whereby, in addition to a conventional sensor S3, a power bank can also be connected as a further external energy storage device PB via a Y-cable YK on the downwardly oriented connector SV4. In this way, the upper sensor module OSM can transmit longer with more energy and/or send measurement data at shorter intervals.

[0144] In all other respects, the structure of the radio sensor module FSM shown corresponds in particular to the embodiment shown in FIGS. 4A and 4B.

[0145] FIG. 8 shows a sectional view of a possible further embodiment of a dismantled radio sensor module FSM according to the invention with a coupling connector KV1 for connecting the upper sensor module OSM and the lower sensor module USM, comprising, among other things, a sensor S and a sensor board SP.

[0146] Thereby, in this embodiment, the radio sensor module FSM comprises the universal radio transmission connection UFSV3 at a process P in addition to the coupling connector KV1 as an electrical module coupling section.

[0147] For this purpose, the upper sensor module OSM and the lower sensor module USM are connected to each other, in particular via a fixed coupling connector KV1, comprising pin contacts ST on the part of the upper sensor module OSM and socket contacts BU on the part of the lower sensor module USM, the lower sensor module USM being mounted with its process port PA on a process P, so that no further fastening devices are required.

[0148] In particular, radio transmission connection UFSV3 is designed in such a way that on the upper sensor module OSM only electrical socket contacts BU are mounted, which are tin-plated, and on the lower sensor module USM, on the other hand, robust and durable pin contacts ST are mounted, which are round in design.

[0149] In addition, the coupling connector KV1 has in particular only four, at most five contacts, and is thus built in a very compact way and has a captive retaining ring SOSI with thread G1A, which is designed, for example, as an M12 thread and is mounted on the female connector of the upper sensor module OSM.

[0150] The upper thread G1A engages in a thread G2A on the connector section STA of the lower sensor module USM.

[0151] Optionally, the upper sensor module OSM and the lower sensor module USM can also be separated at this middle module interface and connected by cable using a coupling connector KV so that the upper sensor module OSM can be placed at a location where improved transmitting and receiving conditions exist. Also, the coupling connector KV has in particular only four, at most five contacts and has a captive retaining ring SOSI with thread G2B, which is formed for example as M12 thread and is designed for fastening to the thread G2A of the connector section STA of the lower sensor module USM. Furthermore, the coupling connector KV has an upper connector section STA1 with a thread G1B, which is formed for fastening to the thread G1A of the upper sensor module OSM.

[0152] In particular, a user has the possibility of exchanging an energy storage device ES1 for another energy storage device ES2, in particular for another battery BA, by loosening the housing cap KG1. This energy storage device ES2 can also have an additional capacity ZK and thus a longer design.

[0153] Furthermore, the radio board FP and consequently also the radio standard can be exchanged without changing a measuring point, the upper sensor module OSM or the entire radio sensor module FSM including the lower sensor module USM or without decoupling it from the process P.

[0154] FIG. 9A shows a possible example of a radio sensor module FSM according to the invention in an application environment using two connection protocols P1, P2 for transmitting measured values or for communication.

[0155] Here, the upper sensor module OSM is connected via a first connection protocol P1 to a receiving station GW1 for evaluating and displaying measured values on a terminal TM. This forms a communication path UP1. Furthermore, the upper sensor module OSM is connected to a mobile terminal device MBT of a user US via a second connection protocol P2. This forms a further communication path UP2.

[0156] The mobile terminal device MBT has a position determination and a voice interface via which the user US can request measured values, for example also via voice and dictation services.

[0157] When approaching a radio sensor FS, a message can be output via an available device in this case even if the distance falls below a local space or radius.

[0158] For this purpose, communication to the mobile terminal device MBT takes place via the second protocol P2, in particular via a mobile network or the Internet IN or via GSM services, with a second receiving station GW2 and/or a database DB. The first connection protocol P1 can also be implemented, for example, as a so-called Https push service in the form of a so-called JSON file.

[0159] Thus, the communication paths UP1, UP2 are formed, over which, in particular over different transmission types, sensor data are sent redundantly to different receivers.

[0160] FIG. 9B shows a possible example of a radio sensor module FSM according to the invention in a further application environment in a building G.

[0161] Messages and measured values of a radio sensor FS can be triggered here on the one hand by a local approach and/or falling below a distance and on the other hand by threshold values stored in the radio sensor module FSM if these are exceeded during a measurement.

[0162] The approach of the mobile terminal device MBT to the radio sensor module FSM can also be implemented in this case by satellite-based position determination GPS, in which case one or more positions of a radio sensor FS or of sensors S are initially determined during a configuration and are determined by the associated mobile terminal device MBT during a configuration and are stored in a database DB for position evaluations for a radio sensor FS or sensor S. In particular, this allows all devices in an available radius to perform a comparison to such a database DB on request, without each radio sensor FS having its own satellite-based positioning GPS.

[0163] The invention is not limited to the foregoing detailed embodiments. It may be modified to the extent set forth in the following claims. Likewise, individual aspects from the subclaims may be combined.

[0164] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
