[Technical field]

[0001] The present invention relates to a wireless sensor module and a modular system for forming a wireless sensor module. [Background technology]

[0002] Wireless sensor modules for transmitting measurement values ​​are known in the prior art. Summary of the Invention [Problem to be solved by the invention]

[0003] SUMMARY OF THE PRESENT EMBODIMENT It is an object of the present invention to provide a novel wireless sensor module and a novel modular system for forming the wireless sensor module. [Means for solving the problem]

[0004] The above object is achieved according to the present invention by a wireless sensor module having the configuration recited in the characterizing portion of claim 1 and a modular system having the configuration recited in the characterizing portion of claim 30.

[0005] The subject matter of the dependent claims of claim 1 form possible embodiments of the invention.

[0006] The wireless sensor module according to the invention is especially designed to transmit measurement data obtained by pressure, temperature, flow or level measurement. The wireless sensor module comprises at least one sensor board with a sensor and / or a sensor base module with a connection for connecting a sensor external to the wireless sensor module. The wireless sensor module further comprises a wireless sensor unit with a process connection and / or an extended sensor connection, a housing part for accommodating the sensor base module and the sensor board, and a structural support. The structural support supports therein the wireless board and an energy storage device for supplying the wireless board with electrical energy, the energy storage device having a battery and a capacitor electrically connected in parallel.

[0007] The battery provides energy to the wireless sensor module during continuous operation. The parallel connected capacitor is provided as a buffer to take over or assist the power supply especially when current spikes occur and / or during the start-up current phase of the wireless sensor module. In particular, the capacitor supports the battery voltage when the battery is started again after a long down time and initially a voltage drop occurs during the start-up of the battery chemical reaction.

[0008] In one embodiment of the wireless sensor module, the battery is a lithium battery, in particular a lithium battery powered on a lithium-thionyl chloride basis. Furthermore, the capacitor is an electric double layer capacitor with lithium intercalation-based electrodes and / or structures. Such structures allow the accumulation of atoms, ions or small molecules between the crystal lattice planes of layered crystals. In this case, batteries and capacitors of such configurations have low internal resistance and provide high current pulses. As an alternative to the pure thionyl chloride structure (SOCl2), it can also be used in more optimized mixtures, such as, for example, sulfuryl chloride (SO2Cl2) combined with thionyl chloride and lithium (Li).

[0009] For example, a lithium battery is characterized by containing 10% to 30% mass fraction of lithium-cobalt-nickel oxide, and 10% to 20% mass fraction of graphite or carbon (C6), and 15% to 50% mass fraction of the aforementioned lithium-thionyl chloride. For example, the electrolyte of a lithium battery basically contains tetrachloroaluminate dissolved in thionyl chloride. Based on the electrochemical reaction, thionyl chloride is the active depolarizing agent. Therefore, thionyl chloride is often called catholyte or liquid cathode. The cathode is formed, for example, from highly porous acetylene black with Teflon binder. The remaining components are nickel-plated metal contacts and a housing. However, these components have a weight of, for example, 17 grams to 20 grams. For example, the nominal output is 2.2 Ah to 3.0 Ah when the voltage is 3 volts to 4 volts. For example, the average sustained discharge current for a lithium battery is approximately 100 mA depending on the cycle, and therefore is optimally backed up with a capacitor to buffer short duration current spikes.

[0010] For example, the pulse current capacity of the capacitor is up to 0.5 amps, 0.75 amps or 1 amp when the weight is 3.0 grams to 5.0 grams. For example, the nominal output is 0.05Wh to 0.10Wh when the voltage is 3 volts to 4 volts. Therefore, hybrid layer capacitors are used.

[0011] In another possible embodiment of the wireless sensor module, the battery capacity is between 5 Wh and 15 Wh and the capacitor capacity is between 90 Ws and 220 Ws, such values ​​being known to be particularly suitable for use in wireless sensor modules.

[0012] In another possible embodiment of the wireless sensor module, the capacitor can be electrically charged by a battery, in particular during normal operation, so that the capacitor is always charged to act as a buffer.

[0013] In another possible embodiment of the wireless sensor module, the energy storage device and the radio board are arranged crosswise in the wireless sensor unit, thereby achieving a compact arrangement of the energy storage device and the radio board.

[0014] In another possible embodiment of the wireless sensor module, the intersection angle between the axial surface of the wireless sensor unit and the axial surface of the energy storage device is greater than 0 degrees and the extensions of the two axial surfaces intersect externally, thereby achieving a particularly compact arrangement of the energy storage device and the wireless substrate.

[0015] In other possible embodiments of the wireless sensor module, the two axially viewed surfaces extend substantially perpendicular to the central axis of the housing part, or the energy storage device and the wireless substrate are arranged such that their respective axially viewed surfaces are parallel to each other.

[0016] In another possible embodiment of the wireless sensor module, the energy storage device and the wireless board are arranged around the central axis of the wireless sensor unit, or the energy storage device and the wireless board are arranged along the central axis of the wireless sensor unit, thereby achieving better space utilization.

[0017] In another possible embodiment of the wireless sensor module, the radio board has an upper part and a lower part, in the upper part an antenna is mounted on the radio board, and below the antenna a connector is arranged which is coupled to the energy storage device, thereby realizing a space-saving arrangement of the antenna and the connector and a simple coupling to the radio board.

[0018] In another possible embodiment of the wireless sensor module, the wireless sensor unit has a housing cap that is mechanically coupled to a structural support or to an intermediate ring arranged between the sensor base module and the wireless sensor unit, the housing cap in particular sealingly enclosing the energy storage device and the radio substrate and protecting them from external influences.

[0019] In another possible embodiment of the wireless sensor module, an O-ring is arranged between the housing cap and the structural support or between the housing cap and the intermediate ring, thereby providing an inexpensive and reliable seal.

[0020] In another possible embodiment of the wireless sensor module, the housing cap and the structural support or the housing cap and the intermediate ring have connecting elements for forming a bayonet connection, which allows a simple and stable connection and a simple disconnection.

[0021] In another possible embodiment of the wireless sensor module, the housing cap has an inner abutment and / or an inner step, by means of which the energy storage device is axially fixed. Alternatively or additionally, the energy storage device is supported in a fixed or vibration-damped manner by at least one spring element, whereby a simple and reliable support and fixing of the energy storage device as well as protection of the energy storage device against shocks are achieved.

[0022] In another possible embodiment of the wireless sensor module, the housing cap is made from plastic, which is lightweight, inexpensive to manufacture, and does not interfere with wireless communication.

[0023] In another possible embodiment of the wireless sensor module, the housing part that receives the sensor base module and the sensor substrate is made from stainless steel, which provides high mechanical stability and high chemical resistance to process media and environmental influences.

[0024] In another possible embodiment of the wireless sensor module, the housing cap and the housing part are connected to one another via a structural support or an intermediate ring, whereby the housing cap and the housing part are connected to one another in a particularly simple manner and without additional parts.

[0025] In another possible embodiment of the wireless sensor module, the structural support has a shaped receiving portion for the energy storage device and the radio board, which receiving portion is formed in particular as a guide portion and which surrounds the energy storage device and the radio board in an interrupted manner and / or supports a U-shaped and / or circular portion, whereby the energy storage device and the radio board can be held simply and reliably without additional holding elements.

[0026] In another possible embodiment of the wireless sensor module, the structural support is formed as a universally applicable conductor plate holder, whereby the inner receiving part or the internal shaft can be coupled with conductor plates of various shapes and / or with various types of energy storage devices, closed and sealed from the outside by various housing caps and opened again when exchanging the energy storage device.

[0027] In another possible embodiment of the wireless sensor module, a metal oxide semiconductor field effect transistor or a microcontroller is provided which is configured to operate the sensor base module.

[0028] In another possible embodiment of the wireless sensor module, the sensor base module processes at least one measured value obtained by the sensor in the active state, and the metal oxide semiconductor field effect transistor or the microcontroller is configured to deactivate the sensor substrate after processing the measured value, in particular after 50 ms to 500 ms, in particular after 200 ms, so that the energy consumption of the wireless sensor module can be reduced.

[0029] This allows the sensor base module to be woken up by an interrupt to request measured values ​​or to be switched on for a defined period of time by a switch element, either periodically depending on the selection, where the cycle of requesting measured values ​​can be set by the user from the outside, in particular via a wireless interface to an app in a mobile terminal device, or via a further interface, such as a universal wireless sensor interface using UART or I2C protocol, for example.

[0030] In another possible embodiment of the wireless sensor module, the metal oxide semiconductor field effect transistor and the microcontroller keep the sensor base module with at least one sensor and / or a connection for connection to a sensor external to the wireless sensor module in a standby mode, thereby reducing energy consumption.

[0031] In another possible embodiment of the wireless sensor module, the metal oxide semiconductor field effect transistor or the microcontroller wakes up the sensor base module with at least one sensor and / or a connection for connection to a sensor external to the wireless sensor module by an interrupt from a standby mode when a measurement value is required, whereby the sensor base module can operate for a maximum time in a low energy consumption standby mode while operating actively for a minimum time when acquisition and transmission of measurement values ​​is required, thereby enabling a particularly low energy consumption operation of the wireless sensor module.

[0032] In another possible embodiment of the wireless sensor module, the sensor base module and the at least one corresponding sensor have a power consumption of, for example, 1 μA in standby mode.

[0033] In further possible embodiments of the wireless sensor module, the sensor is a piezoelectric sensor, a ceramic pressure film sensor, a thin film sensor, a heat flow sensor or an optical level sensor, which sensors obtain corresponding measured values ​​with a particularly high reliability.

[0034] In another possible embodiment of the wireless sensor module, the radio board comprises a transmission unit for data transmission with at least two different radio standards, including Bluetooth and / or WirelessHART and / or specific transmission technologies based on the Chirp Spread Spectrum modulation technology. Alternatively or additionally, the radio board comprises at least one antenna formed as a chip antenna, whereby data transmission with other devices with different radio standards is possible.

[0035] In another possible embodiment of the wireless sensor module, the radio board, when configured for communication in accordance with the Bluetooth standard or WirelessHART, is smaller than a second possible radio board, in particular shorter in the spatial expansion direction.

[0036] In another possible embodiment of the wireless sensor module, the radio board is made to communicate according to the so-called Lora standard, in which case the size of the radio board is large and it uses a circuit board antenna for communication.

[0037] In another possible embodiment of the wireless sensor module, the radio board is designed for communication according to the Lora standard and the Bluetooth standard, in which case the radio board is larger than one designed specifically for communication according to the Bluetooth standard, the structure of the holding in this case is determined in particular by the fact that the printed circuit board is held in the same receiver regardless of the length of the radio board, and both a printed circuit board antenna for communication according to the Lora standard and a chip-type internal antenna for communication according to the Bluetooth standard are used.

[0038] To facilitate communication between the wireless sensor module and the sensor itself and / or sensors external to the wireless sensor module, in another possible embodiment of the wireless sensor module the wireless sensor unit has at least one communication interface, which is configured for data communication with the sensor and / or at least one sensor external to the wireless sensor module.

[0039] In another possible embodiment of the wireless sensor module, the wireless sensor unit has a module connection with an electrical connection and the sensor base module has a module connection with an electrical connection. In this case, the electrical connection allows the transmission of the sensor signal and the transmission of energy. Furthermore, the connection direction of the electrical connections of the module connections of the wireless sensor unit and the sensor base module is in the same direction as the mounting direction of the wireless board and the energy storage device of the wireless sensor unit. This allows the connection of the electrical connections to be easily performed during the assembly of the wireless board and the energy storage device.

[0040] In another possible embodiment of the wireless sensor module, the openings of the process connections or the extended sensor connections face in the same direction as the connection direction of the electrical module connections, which simplifies the assembly of the wireless sensor module and its components.

[0041] In another possible embodiment of the wireless sensor module, at least one module connection has a fastening ring which is tethered, in particular fixed to the wireless sensor unit, the fastening ring allowing for a fastening of the module connection, in which case the tethered configuration makes the module connection easier to handle.

[0042] In another possible embodiment of the wireless sensor module, both module connectors have complementary connection elements for cooperating to form a bayonet connection, which allows a simple and stable connection and easy release of the wireless sensor unit and the sensor base module.

[0043] In another possible embodiment of the wireless sensor module, both module connectors have complementary threads, in particular M12 threads, in order to form a bayonet-type connection for cooperating together, in which case the threads enable a particularly strong connection.

[0044] In another possible embodiment of the wireless sensor module, the electrical connection of one module connector is formed as a socket contact and the electrical connection of the other module connector is formed as a pin contact that mates with the socket contact, thereby enabling a simple, reliable, stable and durable connection.

[0045] In this case, the module connector forms, for example, a robust mating connector of the wireless sensor unit and the sensor base module, and no further fixing devices are required. For example, the mating connector is designed such that only electrical socket contacts are formed on the wireless sensor unit, while robust and durable pin contacts are formed on the sensor base module. For example, the mating connector has 4-5 contacts.

[0046] In another possible embodiment of the wireless sensor module, the mating connector comprises a cable, whereby the wireless sensor unit can be placed remotely from the sensor base unit in a location where improved transmission and reception conditions exist.

[0047] In another possible embodiment of the wireless sensor module, the process connection is designed in such a way that the wireless sensor module is positioned and held only mechanically relative to the complementary connection, whereby no additional positioning and holding means are required.

[0048] In another possible embodiment of the wireless sensor module, the wireless sensor module comprises a detection unit for detecting the approach of the mobile terminal to the wireless sensor based on position data previously stored in a database, while consulting the actual position of the mobile terminal with the position data of the database. This leads to the possibility that a notification about the mobile terminal is output when the mobile terminal approaches the wireless sensor module, for example when the positional space and / or radius is not reached. In this case, the notification and the measurement value of the wireless sensor can be triggered not only by a positional approach below a certain distance, but also by a threshold value stored in the mobile terminal and / or the wireless sensor module if it is exceeded during the measurement.

[0049] The approach may also be detected by a satellite-enabled positioning system based on a mobile terminal, where one or more positions of at least one wireless sensor are detected during deployment and stored in a database for position analysis relative to the wireless sensor by the mobile terminal involved during deployment. In particular, all devices within an available radius may query such a database on demand, even if each wireless sensor does not use its own satellite-enabled positioning system.

[0050] In another possible embodiment of the wireless sensor module, the wireless sensor unit is connected to a receiving station via a first connection protocol for the analysis and display of the measured values ​​and to a mobile terminal of a user via a second connection protocol. The mobile terminal has, in particular, a voice interface through which the user can determine the position and request the measured values ​​by voice and dictation services. When approaching the wireless sensor unit, a notification can be output via the available devices even if the location space and / or radius is not reached. For this purpose, communication with the mobile terminal takes place via the second connection protocol, in particular via a mobile network, the Internet or GSM services. On the other hand, the first connection protocol can be implemented, for example, as an https push service in the form of a so-called JSON (JSON = JavaScript Object Notation) file.

[0051] In another possible embodiment of the wireless sensor module, the sensor base module forms the lower sensor module and the wireless sensor unit forms the upper sensor module. An EMV board is arranged between the radio board and the sensor board, and the overall electrical connection between the lower sensor module and the upper sensor module is made by the EMV board. In this case, the terms "lower sensor module", "upper sensor module", "upper and lower" respectively relate to the usual intended use of the wireless sensor module and to the attached drawings. Of course, it is self-evident that in practical use, in practical application of the wireless sensor module to ceiling mounting or other mounting orientations, the upper and lower can be different. In one possible embodiment, the term "lower" is understood to mean the side of the wireless sensor module on which the connection to the processing medium or the external connector is provided. In this case, the EMV board forms in a simple manner the coupling surface between the upper sensor module and the lower sensor module. Furthermore, the EMV board can be designed as a lower standard component at all times, integrating all the means for controlling the electromagnetic compatibility on one board.

[0052] In another possible embodiment of the wireless sensor module, the overall electrical connection between the sensor board, the radio board and the EMV board is formed by connectors fixed to the printed circuit boards of the sensor board, the radio board and the EMV board, the EMV board forming the sealing part between the wireless sensor unit and the sensor base module. By forming the connectors, a simple electrical connection of the sensor board, the radio board and the EMV board is realized. By forming the sealing part by the EMV board, a simple seal between the wireless sensor unit and the sensor base module is realized without additional sealing elements.

[0053] In another possible embodiment of the wireless sensor module, the connector is formed as at least one at least six-pole connecting plug and is provided as internal data protocol with UART protocol or I2C protocol. Such a configuration can be realized simply and at low cost.

[0054] In another preferred embodiment of the wireless sensor module, the EMV board is sealedly connected to a part of the housing of the lower sensor module, or to the structural support, or to the intermediate ring, and / or the EMV board is sealedly guided in the housing, or to the structural support, or to the intermediate ring. This arrangement makes it possible to very easily realize a seal between the wireless sensor unit and the sensor base module without additional sealing elements, and easy handling of all components when assembling and disassembling the wireless sensor module.

[0055] In a further preferred embodiment of the wireless sensor module, the EMV board is simply and reliably coupled to the module coupling of the wireless sensor unit and / or the EMV board is coupled to the sensor board by means of a plug socket connection.

[0056] In a further preferred embodiment of the wireless sensor module, a further sensor connection is provided for coupling to a sensor external to the wireless sensor module, in which case the process connection of the wireless sensor module can be omitted.

[0057] In another possible embodiment of the wireless sensor module, intelligent and / or modifiable software is provided, which can control the timing of the transmission of the sensor's data upon request and / or demand by a control room, a router or an operator, or depending on the charge state of the energy storage device. At the same time, specific operating patterns can be stored and executed by a learning process or by initial settings or by selection from a library.

[0058] The modular system according to the invention for forming the above-mentioned wireless sensor module comprises at least one sensor base module with a sensor board and / or a connection for connecting with a sensor outside the wireless sensor module. The modular system comprises a process connection and / or an extended sensor connection, a housing part for accommodating the sensor base module and the sensor board, and at least one wireless sensor unit with a structural support. The structural support has a mounting structure for accommodating different sizes of wireless boards and different sizes of energy storage devices arranged to supply electricity to the wireless boards, and for attaching and detaching the wireless boards and the energy storage devices without damage. The modular system further comprises a plurality of different sizes of wireless boards and a plurality of different sizes of energy storage devices, in particular a plurality of different sizes of energy storage devices each having a battery and a capacitor electrically connected in parallel. The modular system further comprises different sizes of housing caps that can be mechanically coupled to the structural support, the length of the housing cap from the coupling structure for coupling with the support to the opposite end corresponding to the respective different sizes of the plurality of energy storage devices and / or the plurality of wireless boards.

[0059] The modular system provides a modular structure of the wireless sensor module that allows the coupling of different wireless components, sensor cells or sensor elements with different energy storage devices, which can be accommodated in different sized support structures and corresponding housing caps without structural modifications.

[0060] Furthermore, the modular system allows the wireless sensor unit to be selectively connected through an interface to sensors of the wireless sensor module, sensors external to the wireless sensor module or energy storage devices.

[0061] The modular system further allows different sensor base modules to be combined with different wireless sensor units. Thus, on the one hand, it is possible that the lower sensor module can have a pressure, temperature, flow or level sensor. On the other hand, a sensor base module can be added to the wireless sensor unit, acting as a sensor signal processing module and connecting to sensors outside the wireless sensor module by means of cables, based on different protocols, for example protocols with a current of 4 mA to 20 mA, the so-called HART protocol, the Profibus protocol or other protocols.

[0062] This modular approach allows different existing sensors based on different sensor technologies to be connected to the wireless sensor unit.

[0063] This modularity allows in particular for sensor interfaces that are independent of the sensor size between the wireless sensor unit and the sensor base module or on the sensor signal processing module side.

[0064] In addition to the scalable energy supply concept, which is realized by the different installation spaces for different energy storage devices with different axial lengths of the battery or battery receptacle, a modularity is provided with regard to the used radio standard, whereby different radio boards are fitted and connected to the connector, whereby the radio boards have, in particular, the same circuit board shape and connection structure, in particular only differing in their axial, e.g. longitudinal, extension.

[0065] The modular system thus makes it possible, firstly, on a platform basis, to combine different energy storage devices with different radio boards and radio standards of wireless sensor units, and, on the other hand, to combine them with sensor base modules of different types or sensor sizes, or with existing standard sensors.

[0067] The present invention will now be described in detail with reference to the accompanying drawings, in which: FIG. In all the drawings, corresponding elements are numbered the same.

[0068] FIG. 1 shows a possible embodiment of a wireless sensor FS according to the prior art. The radio sensor FS comprises an antenna A which is integrated and coupled to a radio substrate FP and a sensor S which belongs to a sensor substrate SP, the antenna A being integrated as a component in the housing cap KG.

[0069] The sensor board SP transmits the sensor data via the antenna A and for this purpose obtains electrical energy from a standalone energy storage device ES, for example an accumulator or a battery. In addition to transmitting, the sensor board SP is also formed for evaluating and processing the sensor data acquired by the sensor S.

[0070] FIG. 2 shows another possible embodiment of a wireless sensor FS according to the prior art. In contrast to the embodiment shown in FIG. 1, the antenna A is mounted on the outside of the housing cap KG.

[0071] FIG. 3A is a cross-sectional view of a possible embodiment of a wireless sensor module FSM according to the invention. The wireless sensor module FSM has an upper sensor module OSM and a lower sensor module USM coupled thereto.

[0072] In the exemplary embodiment shown, the sensor S, which is configured as a pressure sensor or a temperature sensor, belongs to a sensor substrate SP, both of which are arranged in a lower sensor module USM.

[0073] The sensor board SP is coupled to the radio board FP via the EMV board EMV and forms an interface between the upper sensor module OSM and the lower sensor module USM.

[0074] In the upper sensor module OSM, an antenna A formed as a radio antenna is mounted on a radio substrate FP.

[0075] The radio substrate FP and the sensor substrate SP are, as becomes apparent from Fig. 4A, connected to an energy storage device ES for the energy supply, which comprises a battery BA formed as an accumulator and a capacitor K. In this case, a housing cap KG encloses in a sealed manner the energy storage device ES and the radio substrate FP, i.e. at least essentially the upper sensor module OSM.

[0076] FIG. 3B is another cross-sectional view of the wireless sensor module FSM in the plane SA of FIG. 3A, revealing the arrangement of the battery BA and the capacitor K at the location of the wireless substrate FP.

[0077] Both the battery BA and the capacitor K are housed inside an upper sensor module OSM in the wireless sensor unit and are held in a predetermined orientation relative to each other by a structural support TT or support shown in detail in Fig. 4A, where the structural support TT is formed to house one or different radio boards FP, i.e. radio circuit boards.

[0078] To achieve a compact configuration, the axis G1 of the substrate surface of the radio substrate FP intersects with the axis G2 of the intermediate surface of the combined energy storage device consisting of the battery BA and the capacitor K, and the intersection SCP of these two surfaces has an angle α of 5° to 35° or 10° to 60°.

[0079] In this case, the battery BA and the capacitor K are electrically connected in parallel to each other. By adopting such an internal configuration, circuit boards of different shapes and batteries of different types can be combined with each other. This will be described in detail in the following examples.

[0080] FIG. 4A is a cross-sectional view of another possible embodiment of a wireless sensor module FSM according to the invention, in particular a more detailed principle diagram of the wireless sensor module FSM of FIGS. 3A and 3B.

[0081] Here, the wireless sensor unit is arranged as an upper sensor module OSM on a lower sensor module USM.

[0082] Also, a sensor S is arranged in the lower sensor module USM and is coupled to a sensor substrate SP for evaluation and amplification of the sensor data.

[0083] The sensor S is surrounded by a lower receiving part AUT, which receives the sensor S and the sensor substrate SP in a particularly sealed manner, and which forms a connection with a threaded lower process connection PA.

[0084] Furthermore, the lower housing AUT has an apparatus connection surface GA on its outer side. A user can use a tool to couple the lower housing AUT to a process through the apparatus connection surface GA, in particular to fix the lower housing AUT to the process in a sealed state.

[0085] For example, the lower portion AUT may be formed in a bowl shape and may surround the process connection PA as shown. The process connection PA may be welded or preformed to the lower portion AUT. Although not shown in detail in the embodiment, the process connection PA is not a component of the lower portion AUT.

[0086] The upper sensor module OSM has a structural support TT or support which houses an energy storage device with a battery BA and a capacitor K together with a radio substrate FP with an integrated antenna A.

[0087] A battery BA and a capacitor K are coupled to the radio board FP through a connector SV1 and supply electrical energy on demand from all boards of the upper sensor module OSM.

[0088] The spring element FE fixes the battery BA and the capacitor K within the structural support TT by means of an elastic biasing force, and absorbs vibrations exerted from the outside on the energy storage device ES.

[0089] The radio board FP has an antenna A formed either as an integrated conductive track or as an on-board mounted component.

[0090] The radio board FP is coupled through a second connector SV2 to the EMV board EMV, which forms the interface between the upper sensor module OSM and the lower sensor module USM.

[0091] The EMV board EMV is coupled to the sensor board SP through another connector SV3, which in this case transmits both sensor data and energy, but is further formed with a number of pin contacts, by means of which a further lower sensor module USM can be coupled.

[0092] In particular, this connection portion SV3 is formed in such a way that a universal wireless communication connector UFSV is brought into this position.

[0093] The interface thus formed is also characterized in that the sensor S or the sensor board SP connected at this location is switched on briefly within the time window for the respective interrogation of the measured value, for example by passing a current through a MOSFET or beyond a start value at the request and control of the radio board FP, so that the switching on and off of the lower sensor module USM is performed at a time or timing determined in software or memory or set by the user via wireless control with a mobile communication terminal.

[0094] This is carried out, for example, by an app via the wireless standard Bluetooth or by remote access according to another wireless protocol, for example the so-called MIOTY or LORAWAN protocols. In this case, an integrated light, for example a light-emitting diode LED, on the wireless board FP communicates the current status to the user. The light is visible, for example, through an opening OE in the housing cap KG.

[0095] The housing cap KG is guided on the structural support TT by means of a bayonet connection BJ and can be removed without tools, and furthermore the housing cap KG has on its inside an abutment AS for axially guiding and limiting the movement of the energy storage device, which abutment AS is provided in the plastic part as a molded step.

[0096] The housing cap KG is also sealed to the central intermediate ring ZR via an O-ring OR, sealingly houses the EMV substrate EMV, and is attached to the housing lower part AUT in a surrounding arrangement in a sealing manner by a welded joint SW.

[0097] FIG. 4B is another cross-sectional view of the wireless sensor module FSM, showing the placement of the energy storage device within the structural support TT.

[0098] This figure shows primarily the structural support TT, which accommodates the battery BA, the capacitor K and the radio circuit board FP. The battery BA and the radio circuit board FP are replaceably guided in the housing cap KG by molded guide ribs AN.

[0099] As shown in FIG. 3B, in order to achieve a compact configuration, the axis G1 of the substrate surface of the wireless substrate FP intersects with the axis G2 of the intermediate surface of the combined energy storage device consisting of the battery BA and the capacitor K, and the intersection SCP of these two surfaces or axes G1, G2 has an angle α of 5° to 35° or 10° to 60°.

[0100] In this case, in particular, the intersection SCP of the two faces is located on the outside of the housing cap KG. In particular, the battery BA and the capacitor K are connected via an integrated circuit which automatically electrically disconnects them from the radio board FP in the event of an overtemperature or overload.

[0101] FIG. 5 is a cross-sectional view of another possible embodiment of the wireless sensor module FSM of the present invention.

[0102] Here too, the intermediate ring ZR accommodates an EMV substrate EMV as an interface between the upper sensor module OSM and the lower sensor module USM, and the intermediate ring ZR is selectively firmly coupled to the structural support part TT or the accommodating lower part AUT.

[0103] The housing cap GK can be removed in the direction (1) after being rotated. Then, from the vertical holes of the structural support part TT, the radio board FP can be pulled out in the direction (2) or the short energy storage device ES-K in the direction (3), i.e. vertically upwards, respectively, and replaced. In this way, both the replacement of the energy storage device ES-K and the replacement of the radio board FP are possible.

[0104] Since different radio boards FP can be used, a change of radio standard or communication type can thus be easily effected, which is supported in particular by the vertical movement of the second connector SV2 provided on the EMV board EMV.

[0105] Also here, the spring element FE fixes and / or supports the energy storage device ES, independent of its length, inside the upper sensor module OSM in a vibration-damping manner.

[0106] The dashed lines represent an alternative arrangement with a larger, particularly longer, energy storage device ES-L. Similarly, the use of a longer radio substrate FP with an antenna A is depicted in dashed lines and represented as an option.

[0107] Depending on the embodiment of the energy storage device ES, ES-K, ES-L, different housing caps GK are attached, which are characterized in particular by different lengths and thus different heights in the extension direction of the wireless sensor module FSM, i.e. in the direction facing the process connection PA.

[0108] Furthermore, the illustrated configuration of the wireless sensor module FSM corresponds in particular to the embodiment shown in FIGS. 4A and 4B.

[0109] FIG. 6A is a partially exploded perspective view of another possible embodiment of a wireless sensor module FSM according to the invention, with a first configuration, i.e. a first device variant.

[0110] In this case, the structural support TT is equipped with a short, compact energy storage device ES-K, which protrudes from the structural support TT by a height B1.

[0111] The radio board FP is of a short type with a height FP1 protruding upward from the structural support part TT, in which case the connector SV1 is directed towards the structural support part TT or the intermediate ring ZR at a position at the height (X) of the upper sensor module OSM.

[0112] A bayonet path BJB is formed on the structural support TT, and when the housing cap KG is attached, a knob BN of the housing cap KG engages with the bayonet path BJB and is fixed by rotation.

[0113] Moreover, the illustrated configuration of the wireless sensor module FSM corresponds in particular to the embodiment shown in FIGS. 4A and 4B.

[0114] FIG. 6B is a partially exploded perspective view of another possible embodiment of a wireless sensor module according to the invention, i.e. a second device variant, with a second configuration.

[0115] In this case, the structural support TT is equipped with a long, large energy storage device ES-L that protrudes from the structural support TT by a height B2, which is greater than the height B1 of the embodiment of the wireless sensor module FSM shown in FIG.

[0116] The radio board FP is of a long type with a height FP2 protruding upward from the structural support part TT, and in this case, the connector SV1 is directed toward the structural support part TT or the intermediate ring ZR at a position of the height (X) of the upper sensor module OSM, similar to the embodiment shown in Figure 6A.

[0117] In all configurations, the connectors SV1 to the energy storage devices ES, ES-K, ES-L are provided at the same height (X) in order to make all combinations possible without lengthening or shortening the cables.

[0118] Moreover, the illustrated configuration of the wireless sensor module FSM corresponds in particular to the embodiment shown in FIGS. 4A and 4B.

[0119] FIG. 7 shows an exploded cross-sectional view of another possible embodiment of a wireless sensor module FSM according to the invention with different forms of a lower sensor module USM with respective possible connectors.

[0120] In this case, the upper sensor module OSM comprises a housing cap KG which houses the radio substrate FP and the energy storage device ES.

[0121] An EMV board EMV is coupled to the upper sensor module OSM via a universal wireless communication connector UFSV2 and is sealingly attached to the intermediate ring ZR, which is also sealingly fixed to the housing cap KG.

[0122] The EMV board EMV has a universal wireless communication connector UFSV3 as a terminal of the upper sensor module OSM. Through the universal wireless communication connector UFSV3, a plurality of different lower sensor modules USM1, USM2, USM3 can be coupled and operated.

[0123] For example, the lower sensor module USM1 with an integrated sensor S, already shown in FIG. 5, is one of these, which is coupled to a process connection PA and is arranged together with an associated sensor substrate SP in the receiving lower part AUT.

[0124] However, it is also possible to arrange another lower sensor module USM2 with a substrate PL2 in the receiving lower part AUT2, in which case, instead of the process connection PA, a connector SV4 is coupled downwards to the substrate PL2. The connector SV4 provides an interface by means of which a conventional sensor S2 is connected via a cable KA.

[0125] Here, the sensor S2 may be configured as a pressure sensor or another sensor and may operate according to the 4 mA to 20 mA standard or according to the so-called HART or Profibus standard. The sensor S2 may also operate according to another sensor protocol. Furthermore, the sensor S2 may be operated by an interrupt or may be sequentially operated or activated by a MOSFET.

[0126] Also, another lower sensor module USM3 can be arranged in the lower housing AUT3 together with the substrate PL3 in contact with the upper sensor module OSM, in which case a power bank as another external energy storage device PB can be connected to the downwardly arranged connector SV4 by means of a Y cable YK alongside the conventional sensor S3. In this way, the upper sensor module OSM can communicate for a longer period with more energy and / or transmit measurement data at shorter time intervals.

[0127] Moreover, the illustrated configuration of the wireless sensor module FSM corresponds in particular to the embodiment shown in FIGS. 4A and 4B.

[0128] FIG. 8 shows an exploded cross-sectional view of another possible embodiment of a wireless sensor module FSM according to the invention, with a mating connector KV1 for coupling an upper sensor module OSM to a lower sensor module USM having a further sensor S and a sensor substrate SP.

[0129] The wireless sensor module FSM of this embodiment has a universal wireless communication connector UFSV3 associated with the process P in addition to a coupling connector KV1 as an electrical module connection portion.

[0130] The upper sensor module OSM and the lower sensor module USM are therefore connected to one another, in particular via a fixed coupling connector KV1, surrounding the pin contacts ST on the upper sensor module USM side and the socket contacts BU on the lower sensor module USM side. In this case, the lower sensor module USM is mounted on the process P via its process connection PA, so that no additional fixing devices are required.

[0131] In particular, the universal wireless communication connector UFSV3 is configured such that only tin-plated socket contacts BU are mounted on the upper sensor module OSM, while robust, long-life, rounded pin contacts ST are mounted on the lower sensor module USM.

[0132] The mating connector KV1 furthermore has a fastening ring SOSI which is in particular made very compact with four, at most five, contacts and is provided with a thread G1A, for example made as an M12 thread, which is provided on the inner circumferential surface of the female connector of the upper sensor module OSM.

[0133] The upper screw G1A engages with the screw G2A of the connector part STA of the lower sensor module USM.

[0134] Alternatively, the upper sensor module OSM and the lower sensor module USM can be separated at this intermediate module interface and coupled with a coupling connector KV with a cable. Thereby, the upper sensor module OSM can be placed in a place where good communication conditions exist. Furthermore, the coupling connector KV in particular has only four or at most five contacts and is equipped with a universal fastening ring SOSI with a thread G2B. The thread G2B is formed, for example, as an M12 thread and is adapted to engage with a thread G2A of the connector part STA of the lower sensor module USM. Furthermore, the coupling connector KV has a connector part STA1 with a thread G1B, the thread GB1 being adapted to engage with a thread G1A of the upper sensor module OSM.

[0135] In particular, the user can replace the energy storage device ES1 by another energy storage device ES2, in particular another battery BA, by unscrewing the housing cap KG, which also comprises an additional capacitor ZK and is therefore longer in length.

[0136] Furthermore, the radio board FP, and thus the radio standard, can be exchanged without the entire wireless sensor module together with the measuring location or the upper sensor module OSM or the lower sensor module USM being changed or disconnected from the process P.

[0137] FIG. 9A shows a possible embodiment of a wireless sensor module FSM according to the invention placed in an application environment using two connection protocols P1, P2 for the transmission or communication of measurement values.

[0138] Here, the upper sensor module OSM is connected according to a first connection protocol P1 to a receiving station GW1, which evaluates the measured values ​​and displays them on a terminal TM, thereby forming a communication path UP1. Furthermore, the upper sensor module OSM is connected according to a second connection protocol P2 to a mobile terminal MBT of a user US, thereby forming a further communication path UP2.

[0139] The mobile terminal MBT comprises a positioning system and a voice interface, through which the user US can request measurements, for example by means of voice and dictation services.

[0140] When approaching a wireless sensor FS, a notification may also be made through available devices if its positional space and / or radius is not reached.

[0141] Thereby, communication between the mobile terminal MBT and the second receiving station GW2 and / or the β-base DB takes place via a second connection protocol P2, in particular a mobile network or Internet IN or GSM service. The first connection protocol P1 can also be implemented as a Https Push service, for example in the so-called JSON file format.

[0142] Thus, communication paths UP1, UP2 are formed, over which the sensor data are transmitted in a redundant manner to different receivers, in particular in different communication formats.

[0143] FIG. 9B shows another possible embodiment of a wireless sensor module FSM according to the invention, placed in an application environment in a building G.

[0144] In this case, notifications and measurement values ​​of the wireless sensor FS can be issued, on the one hand, by positional proximity and / or reaching within a certain distance range, and, on the other hand, by threshold values ​​stored in the wireless sensor module FSM being exceeded during the measurement.

[0145] The approach of the mobile terminal MBT to the wireless sensor module FSM is also carried out by means of a satellite-based positioning GPS, where first the position(s) of the wireless sensor FS or sensor S are measured during installation, then the position(s) of the associated mobile terminal MBT are measured during installation and stored in a database DB for the position measurements of the wireless sensor FS or sensor S. In particular, this allows all devices located within the available radius to query this database DB on request, even if each wireless sensor FS does not have its own satellite-based positioning GPS.

[0146] The invention is not limited to the specific embodiments described above, but rather can be modified within the scope of the appended claims, and individual features recited in the appended claims can be combined with one another. [Explanation of symbols]
