Description

Technical Field

[0001] This invention relates to a wireless sensor module and a modular system for forming the wireless sensor module. Background Technology

[0002] Existing technologies typically include wireless sensor modules for transmitting measurement values. Summary of the Invention

[0003] The objective of this invention is to describe a novel wireless sensor module and a modular system for forming the wireless sensor module.

[0004] According to the present invention, the task is accomplished by a wireless sensor module having the features of claim 1 and by a modular system having the features of claim 30.

[0005] Possible embodiments of the present invention are the subject of the dependent claims.

[0006] The wireless sensor module according to the invention is particularly configured for transmitting measurement data obtained from pressure, temperature, flow rate, or level measurements. The wireless sensor module includes a sensor base module having at least one sensor circuit board containing a sensor and / or a connector for connecting to a sensor external to the wireless sensor module. Furthermore, the wireless sensor module includes a process connector and / or an extended sensor connector, a housing section accommodating the sensor base module and the sensor circuit board, and a wireless sensor unit having a structural support. The structural support itself carries the wireless circuit board and an energy storage device supplying electrical power to it, wherein the energy storage device includes an electrical battery and an electrical capacitor. The battery and capacitor are electrically connected in parallel.

[0007] Here, the battery provides the power supply for the wireless sensor module during continuous operation. The parallel capacitor setup serves to buffer and absorb or support the power supply, especially during current spikes and / or inrush current phases of the wireless sensor module. The capacitors also support the battery voltage, particularly when the battery restarts after a long period of dormancy, and in this case, when a voltage drop initially occurs as the battery chemistry begins to function.

[0008] In one possible implementation of the wireless sensor module, the battery comprises a lithium battery, particularly based on lithium-thionyl chloride. Furthermore, the capacitor is constructed as a hybrid layer capacitor, comprising electrodes and / or a battery structure based on a lithium intercalation compound.

[0009] This structure allows atoms, ions, or small molecules to intercalate between the lattice planes of a layered crystal. Batteries and capacitors constructed in this way exhibit low internal resistance and can provide high-current pulses. Instead of the pure thionyl chloride structure (SOCl2), this structure can also be used in other optimized mixtures, such as a combination of thionyl chloride (SO2Cl2) with thionyl chloride and lithium (Li).

[0010] For example, lithium batteries are characterized by a mass fraction of 10% to 30% cobalt-nickel lithium oxide, 10% to 20% graphite or carbon (C6), and 15% to 50% lithium thionyl chloride. The electrolyte of a lithium battery primarily comprises, for example, a solution of lithium tetrachloroaluminate in thionyl chloride. According to the electrochemical reaction, thionyl chloride is also an active depolarizer. Therefore, this electrolyte is often referred to as the cathode or liquid cathode. The cathode is, for example, made of highly porous acetylene black with a Teflon binder. The remaining components are nickel-plated steel contacts and a housing. These components, for example, have a total mass of 17 to 20 grams. At a voltage of 3 to 4 volts, the rated power is, for example, 2.2 Ah to 3.0 Ah.

[0011] Depending on the cycle, the average continuous discharge current of a lithium battery is, for example, about 100mA, so combining it with a capacitor to buffer short-term current peaks is an optimized complement.

[0012] The capacitors have pulse current capabilities, for example, up to 0.5 amps, 0.75 amps, or 1 amp, while weighing only 3.0 grams to 5.0 grams. At voltages of 3 to 4 volts, the rated power is, for example, 0.05 Wh to 0.10 Wh. Therefore, the structural aspect is that of a hybrid layer capacitor.

[0013] In another possible implementation of the wireless sensor module, the intercalation connection is spirally wound to improve performance.

[0014] In another possible implementation of the wireless sensor module, the battery capacity is between 5Wh and 15Wh and the capacitor capacity is between 90Ws and 220Ws. Such values ​​have proven particularly suitable for use in wireless sensor modules.

[0015] In another possible implementation of the wireless sensor module, the capacitor can be electrically charged by the battery, especially during normal operation, so that the capacitor is always charged for buffering.

[0016] In another possible implementation of the wireless sensor module, the energy storage device and the wireless circuit board are arranged interleaved within the wireless sensor unit. This allows for a compact arrangement of the energy storage device and the wireless circuit board.

[0017] In another possible implementation of the wireless sensor module, the intersection angle between the axial surface plane of the wireless sensor unit and the axial surface plane of the accumulator is greater than zero degrees, such that the extensions of the axial surface planes intersect externally. This allows for a particularly compact arrangement of the accumulator and the wireless circuit board.

[0018] In another possible implementation of the wireless sensor module, the axial surface plane is at least substantially perpendicular to the axial extension of the center of the housing section, or the energy storage unit and the wireless circuit board are arranged relative to each other such that their axial surface planes extend parallel to each other.

[0019] In another possible implementation of the wireless sensor module, the energy storage unit and the wireless circuit board are arranged off-center relative to the central axis of the wireless sensor module, or the energy storage unit and the wireless circuit board are arranged along the central axis of the wireless sensor unit. This allows for better space utilization.

[0020] In another possible implementation of the wireless sensor module, the wireless circuit board has an upper segment and a lower segment, wherein the antenna is mounted on the wireless circuit board in the upper segment, and a plug connector coupled to an energy storage device is disposed below the antenna. This allows for a space-saving arrangement of the antenna and plug connector, as well as simple coupling of the wireless circuit board.

[0021] In another possible implementation of the wireless sensor module, the wireless sensor unit includes a housing cover that is mechanically coupled to a structural support or an intermediate ring disposed between the sensor base module and the wireless sensor unit. The housing cover particularly seals around the energy storage device and the wireless circuit board and thus prevents external influences.

[0022] In another possible implementation of the wireless sensor module, an O-ring is provided between the housing cover and the structural support or between the housing cover and the intermediate ring, which enables an inexpensive and reliable seal.

[0023] In another possible implementation of the wireless sensor module, the housing cover and structural support, or the housing cover and intermediate ring, have locking elements for forming a bayonet lock. The bayonet lock enables an easy-to-establish, stable, and easy-to-disassemble connection.

[0024] In another possible implementation of the wireless sensor module, the housing cover has internal stops and / or internal steps, wherein the accumulator is axially secured by means of the stops and / or steps. Alternatively or additionally, the accumulator is secured by at least one spring element or supported in a vibration-damping manner. This enables simple and reliable support and fixation of the accumulator and protects it from impacts.

[0025] In another reliable implementation of the wireless sensor module, the housing cover is made of plastic and is therefore particularly lightweight, low-cost, and does not interfere with wireless communication.

[0026] In another possible implementation of the wireless sensor module, the housing section accommodating the sensor base module and sensor circuit board is made of stainless steel. This results in high mechanical stability and chemical resistance to process media and environmental influences.

[0027] In another possible implementation of the wireless sensor module, the housing cover and housing segments are connected to each other via a structural support or intermediate ring, and thus are particularly simple to connect without the need for additional components.

[0028] In another possible implementation of the wireless sensor module, the structural support has molded receptacles for the energy storage unit and the wireless circuit board, wherein the receptacles are particularly configured as guide sections that partially surround the energy storage unit and the wireless circuit board and / or support them with U-shaped and / or circular sections. This allows for simple and reliable fixation of the energy storage unit and the wireless circuit board without the need for additional fixing components.

[0029] In another possible implementation of the wireless sensor module, the structural support is constructed as a universal printed circuit board support, wherein the internal housing or internal channels are combined with different circuit board geometries and / or different types of accumulators and are closed and sealed from the outside using different housing covers, and can be reopened when the accumulator is replaced.

[0030] In another possible implementation of the wireless sensor module, a metal-oxide-semiconductor field-effect transistor or microcontroller is provided, which is accordingly configured to activate the sensor base module.

[0031] In another possible implementation of the wireless sensor module, the sensor base module processes at least one measurement value acquired by the sensor while in an active state, and the metal-oxide-semiconductor field-effect transistor or microcontroller is configured to deactivate the sensor base module after processing the measurement value, particularly after 50 ms to 500 ms, especially after 200 ms. Therefore, the power consumption of the wireless sensor module can be reduced.

[0032] This allows the sensor base module to be woken up by an interrupt or turned on at a specific time via a switching element in order to request a measurement value. Depending on the choice, this can be repeated cyclically. The clock for requesting the measurement value can be set externally by the user, particularly via a wireless interface using an app on a mobile device, or via another interface, such as using UART or I... 2 The C protocol provides a universal wireless sensor interface setup.

[0033] In another possible implementation of the wireless sensor module, the metal-oxide-semiconductor field-effect transistor and microcontroller are configured to enable the sensor base module to remain in standby mode using the at least one sensor and / or using a connector for connecting to a sensor external to the wireless sensor module, and thus further reduce power consumption.

[0034] In another possible implementation of the wireless sensor module, a metal-oxide-semiconductor field-effect transistor or microcontroller enables the sensor base module to be activated from standby mode upon interruption request for measurement values, utilizing at least one sensor and / or a connector for connecting to a sensor external to the wireless sensor module. Therefore, the sensor base module can operate in standby mode with low power consumption for a maximum period of time and actively operate only for a minimum period of time when measurement values ​​need to be acquired and transmitted. This enables a particularly low-power operation mode for the wireless sensor module.

[0035] In another possible implementation of the wireless sensor module, the current consumption of the sensor base module and the at least one corresponding sensor in standby mode is less than 1 μA.

[0036] In another possible implementation of the wireless sensor module, the sensor is a piezoelectric sensor, a thick-film ceramic sensor, a thin-film sensor, a heat flow sensor, or an optical level sensor. These types of sensors are particularly reliable in acquiring the corresponding measurements.

[0037] In another possible implementation of the wireless sensor module, the wireless circuit board includes a transmission unit for transmitting data in at least two different wireless standards, wherein the wireless standards include, for example, Bluetooth and / or Wireless HART and / or proprietary transmission methods based on chirped spread spectrum modulation technology. Alternatively or additionally, the wireless circuit board includes at least one chip antenna. This enables data transmission to other devices that may have different wireless standards.

[0038] In another possible implementation of the wireless sensor module, the wireless circuit board, when constructed for transmission according to the Bluetooth standard or wireless HART, is constructed to be smaller than the second possible wireless circuit board, especially shorter in the spatial extension direction.

[0039] In another possible implementation of the wireless sensor module, the wireless circuit board is constructed for transmission according to the so-called LoRa standard, wherein the wireless circuit board has a larger size and is designed to access the printed circuit board antenna for transmission.

[0040] In another possible implementation of the wireless sensor module, the wireless circuit board is constructed for transmission according to the so-called LoRa and Bluetooth standards. Here, the wireless circuit board is longer than in the case of a single construction for transmission according to the Bluetooth standard. A key feature of this existing fixed geometry is that, regardless of the length of the wireless circuit board, the board is fixed within the same housing, and both a printed antenna for transmission according to the LoRa standard and an internal on-chip antenna for transmission according to the Bluetooth standard are used.

[0041] In order to enable simple communication between the wireless sensor module and its own sensors and / or sensors external to the wireless sensor module, in another possible implementation of the wireless sensor module, the wireless sensor unit includes at least one communication interface configured for data transmission with the sensor and / or at least one sensor external to the wireless sensor module.

[0042] In another possible implementation of the wireless sensor module, the wireless sensor unit includes an electrical module coupling section with electrical contacts, and the sensor base module includes an electrical module coupling section with electrical contacts. Here, these contacts enable the transmission of sensor signals and energy. Furthermore, the coupling direction of the electrical contacts of the module coupling sections of the wireless sensor unit and the sensor base module is the same as the assembly direction of the wireless circuit board and the energy storage device of the wireless sensor unit. Therefore, these electrical contacts can be coupled in a simple manner during the assembly of the wireless circuit board and the energy storage device.

[0043] In another possible implementation of the wireless sensor module, the opening of the process connector or extended sensor connector is in the same direction as the coupling direction of the electrical module coupling section, thereby resulting in a simple assembly of the wireless sensor module and its components.

[0044] In another possible implementation of the wireless sensor module, at least one of the module coupling sections has a permanent retaining ring, particularly fastened to the wireless sensor unit. The retaining ring secures the connection of the module coupling section, and its anti-loss arrangement allows for easy manipulation of the module coupling section.

[0045] In another possible implementation of the wireless sensor module, the coupling sections of the two modules have complementary locking elements to form a bayonet lock for common connection. The bayonet lock enables an easily established, stable, and easily detachable connection between the wireless sensor unit and the sensor base module.

[0046] In another possible implementation of the wireless sensor module, the coupling sections of the two modules have complementary threads, particularly M12 threads, to form a bayonet lock for common connection, wherein the threads enable a particularly reliable connection.

[0047] In another possible implementation of the wireless sensor module, the electrical contacts of one module coupling section are configured as socket contacts, and the electrical contacts of the other module coupling section are configured as pin contacts that complement the socket contacts. This enables a simple, reliable, robust, and durable connection.

[0048] Here, the module coupling section forms, for example, a fixed coupling connector for the wireless sensor unit and the sensor base module, thus eliminating the need for other fastening devices. The coupling connector is configured such that only electrical socket contacts are mounted on the wireless sensor unit, while robust pin contacts are mounted on the sensor base module. The coupling connector, for example, has only 4 to 5 contacts.

[0049] In another possible implementation of the wireless sensor module, the coupling connector includes wires, allowing the wireless sensor unit to be placed away from the sensor base unit at a location with improved transmission and reception conditions.

[0050] In another possible implementation of the wireless sensor module, the process connector is configured to allow the wireless sensor module to be mechanically positioned and held on complementary connectors only. Therefore, no additional positioning and holding devices are required.

[0051] In another possible implementation of the wireless sensor module, the wireless sensor module includes a data acquisition unit configured to acquire the proximity of the mobile terminal device to the wireless sensor by comparing the actual location of the mobile terminal device with location data previously stored in the database. This results in the mobile terminal device outputting information when approaching the wireless sensor module, for example, when reducing to a certain local space and / or activity radius. This information and the wireless sensor's measurement value can be triggered not only by local proximity or reduction to a certain distance, but also by a threshold stored in the mobile terminal device and / or the wireless sensor module if the measurement exceeds a threshold value.

[0052] In this context, proximity can also be determined using a satellite-based positioning system with the aid of a mobile terminal device, wherein the location of one or more wireless sensors is initially determined during configuration and stored in a database by the associated mobile terminal device during configuration for use in evaluating the location of the wireless sensors. In particular, comparisons with such a database can be performed on demand by all devices within the requested available operational radius, without each wireless sensor having its own satellite-based positioning system.

[0053] In another possible implementation of the wireless sensor module, the wireless sensor module connects to a receiving station via a first connection protocol for evaluating and displaying measurements, and connects to a user's mobile terminal device via a second connection protocol. The mobile terminal device includes, in particular, a positioning system and a voice interface, through which the user can also request measurements via voice and dictation services. In this case, information can be output via available devices even when the user is near the wireless sensor unit, even if reduced to a local space or activity radius. For this purpose, communication with the mobile terminal device is conducted via the second protocol, particularly via mobile networks, the Internet, or GSM services. The first protocol can also be implemented, for example, as an HTTPS push service in the form of a so-called JSON file (JSON = JavaScript Object Notation).

[0054] In another possible implementation 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 (Electromagnetic Compatibility) circuit board is disposed between the wireless circuit board and the sensor circuit board, through which all electrical connections constructed between the lower and upper sensor modules are guided. Here, the concepts of "lower sensor module," "upper sensor module," "lower," and "upper" refer to the generally intended use of the wireless sensor module or to the accompanying drawings. Of course, in practical applications, the wireless sensor module may be "overhead" mounted or have other mounting orientations, where the upper and lower parts may be different. In one possible implementation, the concept of "lower" is understood as the side of the wireless sensor where a connector for a plug connection to a process medium or external source is provided. Here, the EMV circuit board is formed in a simple manner on the coupling surface between the respective upper and lower sensor modules. Furthermore, the EMV circuit board integrates all the devices for regulating electromagnetic compatibility on a single circuit board, which can be constructed identically as a standard component of the lower level.

[0055] In another possible implementation of the wireless sensor module, all electrical connections between the sensor circuit board, the wireless circuit board, and the EMV circuit board are implemented via plug connectors securely mounted on printed circuit boards of the sensor circuit board, the wireless circuit board, and the EMV circuit board, with the EMV circuit board forming a sealed section between the wireless sensor unit and the sensor base module. The plug connector configuration enables simple electrical connections between the sensor circuit board, the wireless circuit board, and the EMV circuit board. The sealed section formed by the EMV circuit board provides a simple seal between the wireless sensor unit and the sensor base module, eliminating the need for additional sealing elements.

[0056] In another possible implementation of the wireless sensor module, the plug connector is constructed in at least one connector plug with at least six poles and provides UART protocol or I... 2 The C protocol serves as an internal data protocol. This structure allows for simple and low-cost implementation.

[0057] In another possible implementation of the wireless sensor module, the EMV circuit board is hermetically connected to a portion of the lower sensor module housing, structural support, or intermediate ring, and / or the EMV circuit board is hermetically guided within the housing, structural support, or intermediate ring. This implementation provides a particularly simple way to achieve a seal between the wireless sensor unit and the sensor base module, requiring no additional sealing elements and allowing for easy handling of all components during the assembly and disassembly of the wireless sensor module.

[0058] In another possible implementation of the wireless sensor module, the EMV circuit board is coupled to the module coupling section of the wireless sensor unit for simple and reliable coupling, and / or the EMV circuit board is coupled to the sensor circuit board by means of a plug connection.

[0059] In another possible implementation of the wireless sensor module, an extended sensor connector is constructed for coupling with a sensor external to the wireless sensor module. The process connector of the wireless sensor module itself can be omitted here.

[0060] In another possible implementation of the wireless sensor module, intelligent and / or configurable software is provided, which can control the clock for transmitting sensor data based on the expectations and / or requirements of the control room, router, or user, or based on the charging state of the energy storage device. Simultaneously, specific operating modes can be stored and executed through instruction, default, or selection from a program library.

[0061] The modular system according to the invention for forming the aforementioned wireless sensor module includes a sensor base module having at least one sensor circuit board including a sensor and / or a connector for connecting to a sensor external to the wireless sensor module. The modular system also includes a process connector and / or an extended sensor connector, a housing section accommodating the sensor base module and the sensor circuit board, and at least one wireless sensor unit with a structural support. The structural support is configured to accommodate wireless circuit boards of different sizes and energy storage units of different sizes configured to power the wireless circuit boards, and includes fastening structures configured for non-destructive assembly and disassembly of the wireless circuit boards and energy storage units. Furthermore, the modular system includes multiple different wireless circuit boards and multiple energy storage units of different sizes, which in particular include batteries and capacitors electrically connected in parallel with each other. The modular system additionally includes housing covers of different sizes, each of which can be mechanically coupled to one structural support, wherein the corresponding length of the housing cover from the coupling point of the structure for coupling with the structural support to the opposite end corresponds to the different sizes of the energy storage units and / or the different sizes of the different wireless circuit boards.

[0062] Modular systems enable a modular structure for wireless sensor modules, allowing different wireless components, sensor units, or sensor elements to be coupled with different energy storage devices. Here, energy storage devices can be housed in structural supports of varying sizes and adaptable housing covers without requiring structural modifications.

[0063] In addition, the modular system allows the wireless sensor unit to optionally connect to sensors inside the wireless sensor module, sensors outside the wireless sensor module, or energy storage devices via an interface.

[0064] Furthermore, the modular system allows the sensor base module to be combined with different wireless sensor units. Therefore, on one hand, a sensor base module with a lower section containing pressure, temperature, flow, or level sensors can be constructed. On the other hand, a sensor base module can be added to a wireless sensor unit, functioning as a sensor signal processing module and capable of being wired to an external sensor via different protocols (e.g., protocols with currents from 4mA to 20mA, the so-called HART protocol, the Profibus protocol, or any other protocol).

[0065] This modular approach allows various existing sensors to be coupled with wireless sensor units using a variety of sensor technologies.

[0066] This modularity is achieved, in particular, through a sensor interface between the wireless sensor unit and the sensor base module that is independent of the measurement parameters, or in terms of the sensor signal processing module.

[0067] The scalable energy supply concept, through structural spaces designed for different energy storage units of varying lengths along the axis of the battery channel or battery housing, not only offers the possibility of a scalable energy supply concept but also provides modularity regarding the wireless standard used. Here, different wireless circuit boards can be used and connected using plug connectors, wherein the wireless circuit boards, in particular, have the same printed circuit board geometry and connection possibilities, and are different only along one axis (i.e., in their longitudinal deformation).

[0068] Therefore, with the help of the modular system, it is possible for the first time to combine different energy storage devices with different wireless circuit boards and wireless standards on a single platform into a single wireless sensor unit, which in turn is combined with sensor base modules of different types or measurement parameters or sensor base modules with existing standard sensors.

[0084] The corresponding components are labeled with the same reference numerals in all the accompanying drawings. Detailed Implementation

[0085] Figure 1 illustrates a possible embodiment of a wireless sensor FS according to the prior art.

[0086] The wireless sensor FS includes an integrated antenna A and a sensor S coupled to a wireless circuit board FP, the sensor being equipped with a sensor circuit board SP. Antenna A is integrated as a component into the housing cover KG.

[0087] The sensor circuit board SP can transmit sensor data via antenna A, and for this purpose, it draws electrical energy from a single-cell energy storage unit ES (such as a battery or accumulator). In addition to transmission, the sensor circuit board SP is configured to evaluate and process the sensor data acquired using the sensor S.

[0088] Figure 2 illustrates another possible embodiment of the wireless sensor FS according to the prior art.

[0089] Unlike the embodiment shown in Figure 1, antenna A is externally mounted to housing cover KG.

[0090] exist Figure 3A The figure shows a cross-sectional view of a possible embodiment of the wireless sensor module FSM according to the present invention.

[0091] The wireless sensor module (FSM) consists of an upper sensor module (OSM) and a lower sensor module (USM) coupled to it.

[0092] In the illustrated embodiment, a sensor S configured as a pressure or temperature sensor is assigned to a sensor circuit board SP, both of which are located in the lower sensor module USM.

[0093] The sensor circuit board SP is connected to the wireless circuit board FP via the EMV circuit board EMV, forming the interface between the upper sensor module OSM and the lower sensor module USM.

[0094] In the upper sensor module OSM, antenna A, configured as a wireless antenna, is "onboard" mounted on the wireless circuit board FP.

[0095] like Figure 4A As shown in more detail, the wireless circuit board FP and the sensor circuit board SP are coupled to the energy storage unit ES for power supply. The energy storage unit includes a battery BA configured as a storage battery and a capacitor K. The housing cover KG here sealably surrounds the energy storage unit ES and the wireless circuit board FP, that is, at least substantially surrounds the upper sensor module OSM.

[0096] Figure 3B The wireless sensor module FSM is shown in Figure 3A Another cross-sectional view in plane SA shows the positional arrangement of battery BA and capacitor K relative to the wireless circuit board.

[0097] Both the battery BA and the capacitor K are housed within the upper sensor module OSM of the wireless sensor unit and are... Figure 4A The structural bracket TT or bracket components shown in more detail are held together in a predetermined orientation. The structural bracket TT is configured to accommodate one or more wireless circuit boards FP, i.e., wireless printed circuit boards.

[0098] For a compact arrangement, the axis G1 of the board plane of the wireless circuit board FP intersects with the axis G2 of the middle plane of the combined energy storage unit ES consisting of battery BA and capacitor K, and at the intersection point SCP of the two planes, they have an angle α of 5° to 35° or 10° to 60°.

[0099] The battery BA and capacitor K are electrically connected in parallel with each other. Through the design of the internal arrangement shown, different circuit board geometries and different battery types can be combined with each other, as detailed in the following embodiments.

[0100] exist Figure 4A The figure shows a cross-sectional view of another possible embodiment of the wireless sensor module FSM according to the invention, particularly according to... Figure 3A and Figure 3B Detailed schematic diagram of the wireless sensor module FSM.

[0101] Here, the wireless sensor unit is mounted as the upper sensor module OSM on the lower sensor module USM.

[0102] Here, sensor S is also coupled to sensor circuit board SP and is located in the lower sensor module USM to evaluate and amplify sensor data.

[0103] The sensor S is surrounded by a receiver base AUT, which specifically houses the sensor S and the sensor circuit board SP in a sealed manner. The receiver base AUT establishes a connection with the lower process connector PA, on which threads are molded.

[0104] In addition, the receiver base AUT provides a device connection surface GA on its outside, which allows the user to connect the receiver base AUT to a process using tools, and can be secured in a sealed manner.

[0105] For example, the receiver base AUT is constructed in a basin shape and, as shown in this embodiment, includes a process connector PA. This process connector is welded or molded onto the receiver base AUT. In embodiments not shown in detail, the process connector is not part of the receiver base AUT.

[0106] The upper sensor module OSM includes a structural support TT or support component, which houses an energy storage device including a battery BA and a capacitor K, as well as a wireless circuit board FP with an integrated antenna A.

[0107] The battery BA and capacitor K are connected to the wireless circuit board FP via plug connector SV1 and provide power to all circuit boards of the upper sensor module OSM as needed.

[0108] The spring element FE secures the battery BA and capacitor K to the structural support TT with elastic preload and buffers external vibrations for the energy storage device.

[0109] The wireless circuit board FP has an antenna A, which is constructed as an integrated conductor circuit or as a component assembled on the board.

[0110] The wireless circuit board FP is coupled to the EMV circuit board EMV via the second plug connector SV2. The EMV circuit board forms the interface between the upper sensor module OSM and the lower sensor module USM.

[0111] The EMV circuit board is coupled to the sensor circuit board SP via another plug connector SV3. The electrical plug connector SV3 transmits not only sensor data but also energy, but is also designed with multiple pin contacts to allow coupling to other lower sensor modules USM.

[0112] The plug connector SV3 is specifically constructed such that a universal wireless transmission connection UFSV can be provided at this location.

[0113] The interface thus created is characterized in particular by the fact that the sensor S or sensor circuit board SP connected at this location is briefly turned on within a time window for a single query of the measurement value. This can be achieved, for example, by switching on a MOSFET or by using an initial value, at the request and control of the wireless circuit board FP. Therefore, the switching on and off of the lower sensor module USM can be achieved according to a predetermined time or clock, which is determined in software or memory or configured by the user, particularly via wireless control configuration of a mobile communication device.

[0114] This can be accomplished, for example, via Bluetooth wireless standard through an app, or remotely via another wireless protocol (such as the so-called MIOTY or LORWAN protocol). In this case, an integrated light source, such as an LED, on the wireless circuit board FP provides the user with the current status. This light source can be seen, for example, through an opening OE in the housing cover KG.

[0115] The housing cover KG is guided onto the structural support TT via a bayonet lock BJ and can be removed without tools. Furthermore, the housing cover KG has an internal stop AS for axially guiding and confining the accumulator ES; the stop AS can also be constructed as a molded step on a plastic component.

[0116] The housing cover KG is also sealed by an O-ring OR relative to a centered intermediate ring ZR, which sealably houses the EMV circuit board EMV and is securely fastened to the receiver base AUT by a welded connection SW.

[0117] Figure 4B Another cross-sectional view of the wireless sensor module FSM is shown, which illustrates the arrangement of the energy storage ES in the structural support TT.

[0118] This section primarily shows the structural support TT, which houses the battery BA, capacitor K, and wireless circuit board FP. Both the battery BA and the wireless circuit board FP are guided for replacement within the housing cover KG via molded guide ribs AN.

[0119] As shown in 3B, for a more compact arrangement, the axes G1 and G2 of the circuit board plane of the wireless circuit board FP and the plane of the combined energy storage unit ES consisting of the battery BA and the capacitor K also intersect each other here, and the intersection point SCP of the two planes or the axes G1 and G2 of the plane has an angle αa of 5° to 35° or 10° to 60°.

[0120] The intersection of the two planes, SCP, is located specifically outside the housing cover KG. The battery BA and capacitor K are connected here via an integrated circuit that automatically disconnects from the wireless circuit board FP in case of overheating or overload.

[0121] Figure 5 The figure shows a cross-sectional view of another possible embodiment of the wireless sensor module FSM according to the present invention.

[0122] The intermediate ring ZR serves as the interface between the lower sensor module USM and the upper sensor module OSM, and also houses the EMV circuit board EMV. The intermediate ring ZR can optionally be fixedly connected to the structural bracket TT or the receiver base AUT.

[0123] The housing cover GK can be removed after being rotated in direction (1). Afterwards, the wireless circuit board FP can be removed or replaced in direction (2) or the short energy storage unit ES-K can be removed in direction (3) (i.e., vertically upward) from the long cavity of the structural support TT. In this way and method, not only the energy storage unit ES-K can be replaced, but also the wireless circuit board FP can be replaced.

[0124] Because different wireless circuit boards (FP) are possible in this case, the wireless standard or transmission type can also be easily changed in this way. This is particularly supported by the vertical construction of the second plug connector SV2 located on the EMV circuit board (EMV).

[0125] Here, the spring element FE also fixes and / or supports the accumulator ES inside the upper sensor module OSM in a way that buffers vibration, regardless of the length of the accumulator.

[0126] Another assembly with a larger, and particularly longer, energy storage ES-L is shown in dashed lines. Similarly, the use of a longer wireless circuit board FP with antenna A is shown in dashed lines and is indicated as an option.

[0127] Here, depending on the construction of the accumulators ES, ES-K, and ES-L, different housing covers GK can be fitted. These housing covers are characterized in particular by their different lengths, and they are distinguished from each other at different heights in the extension direction of the wireless sensor module FSM, i.e., in the extension direction opposite to that of the process connector PA.

[0128] In other respects, the structure of the wireless sensor module FSM shown is particularly corresponding to Figure 4A and Figure 4B The embodiments shown are illustrated in the figure.

[0129] Figure 6A A perspective view showing another possible embodiment of a partially disassembled wireless sensor module (FSM) according to the invention is shown, which is a first configuration, i.e., a first assembly variant.

[0130] A short accumulator ES-K is mounted on the structural support TT, which extends from the structural support TT at a structural height B1.

[0131] The wireless circuit board FP is configured as a short model, with height FP1 extending out of the structural bracket TT, wherein the plug connector SV1 is oriented in height (X) relative to the structural bracket TT or relative to the intermediate ring ZR in the upper sensor module OSM.

[0132] A bayonet track BJB is molded on the structural support TT. The protrusion BN of the housing cover KG is embedded in the bayonet track during assembly and can be locked by rotation.

[0133] In other respects, the structure of the wireless sensor module FSM shown is particularly corresponding to Figure 4A and Figure 4B The embodiments shown are illustrated in the figure.

[0134] Figure 6B A perspective view showing another possible embodiment of a partially disassembled wireless sensor module (FSM) according to the invention is shown, which is a second configuration, i.e., a second assembly variant.

[0135] A relatively large and long energy storage device ES-L is mounted on the structural bracket TT, extending from the structural bracket TT at a structural height B2. Here, the structural height B2 is greater than that of the wireless sensor module FSM. Figure 6A The embodiment shown in the figure has a structural height B1.

[0136] The wireless circuit board FP is configured as a longer model, with height FP2 extending out of the structural support TT, where the plug connector SV1 is also located. Figure 6A As shown in the embodiment, the upper sensor module OSM is oriented at the same height (X) relative to the structural support TT or relative to the intermediate ring ZR.

[0137] In all configurations, the plug connector SV1 is therefore oriented at the same height (X) relative to the accumulators ES, ES-K, and ES-L, so that all combinations can be achieved without the need to extend or shorten the wires.

[0138] In other respects, the structure of the wireless sensor module FSM shown is particularly corresponding to Figure 4A and Figure 4B The embodiments shown are illustrated in the figure.

[0139] Figure 7 An exploded view of another possible embodiment of the wireless sensor module FSM according to the invention is shown, which has a sensor module USM with a different lower part, shown in a cross section as a platform view along with possible coupling parts.

[0140] The upper sensor module OSM here includes a housing cover KG, which houses the wireless circuit board FP and the energy storage ES.

[0141] In response, the EMV circuit board, which is hermetically supported in the intermediate ring ZR, is coupled via a universal wireless transmission connection, UFSV2. The intermediate ring ZR is also hermetically sealed relative to the housing cover KG.

[0142] As the terminal of the upper sensor module OSM, the EMV circuit board EMV has a universal wireless transmission connection UFSV3, which allows it to couple and drive multiple different lower sensor modules USM1, USM2, and USM3 via wireless transmission.

[0143] This includes, for example, already in Figure 5 The lower sensor module USM1 shown has an integrated sensor S, which is coupled to the process connector PA and is disposed in the receiver base AUT together with the associated sensor circuit board SP.

[0144] However, it is also possible that another sensor module, USM2, with a lower section of circuit board PL2, is located in the receiver base AUT2, where a plug connector SV4 is coupled to circuit board PL2 instead of the downward-facing process connector PA. Plug connector SV4 provides an interface through which a conventional sensor S2 can be connected via wire KA.

[0145] Here, sensor S2 can be configured as a pressure sensor or another type of sensor that operates according to a 4mA to 20mA standard or the so-called HART or Profibus standard. Sensor S2 can also be responsive via another sensor protocol. Furthermore, sensor S2 can be responded to via an interrupt or via sequential response and turn-on of a MOSFET.

[0146] Alternatively, another sensor module, USM3, with a lower portion of the circuit board PL3 in the receiver base AUT3, may be mounted on the upper sensor module OSM. In this configuration, in addition to the conventional sensor S3, a mobile power source, serving as another external energy storage device PB, can be connected via a Y-wire YK to the downward-oriented plug connector SV4. The upper sensor module OSM can thus utilize more energy to transmit measurement data for longer periods and / or at shorter intervals.

[0147] In other respects, the structure of the wireless sensor module FSM shown is particularly corresponding to Figure 4A and Figure 4B The embodiments shown are illustrated in the figure.

[0148] Figure 8The figure shows a cross-sectional view of another possible embodiment of the disassembled wireless sensor module FSM according to the present invention, which has a coupling connector KV1 for connecting the upper sensor module OSM and the lower sensor module USM. The wireless sensor module also includes a sensor S and a sensor circuit board SP.

[0149] In this embodiment, in addition to the coupling connector KV1, the wireless sensor module FSM includes a universal wireless transmission connection UFSV3 at process P as an electrical module coupling section.

[0150] For this purpose, the upper sensor module OSM and the lower sensor module USM are connected to each other via a fixed coupling connector KV1, which includes a pin-shaped contact ST on the upper sensor module OSM side and a socket contact BU on the lower sensor module USM side. The lower sensor module USM is mounted on the process P using its process connector PA, thus eliminating the need for other fastening devices.

[0151] The wireless transmission connection UFSV3 is specifically designed such that only tin-plated electrical socket contacts BU are mounted on the upper sensor module OSM, while round, robust, and durable pin-shaped contacts ST are mounted on the lower sensor module USM.

[0152] Furthermore, the coupling connector KV1 has only four, at most five, contacts, and is therefore constructed quite compactly and has a permanent retaining ring SOSI with threaded G1A, which is constructed, for example, with an M12 thread and is fitted onto the socket connector of the upper sensor module OSM.

[0153] The upper thread G1A engages with the lower sensor module USM's connector section STA thread G2A.

[0154] Optionally, the upper sensor module OSM and the lower sensor module USM can also be separated at the intermediate module interface and connected using a wired coupling connector KV, allowing the upper sensor module OSM to be positioned where improved transmission and reception conditions exist. The coupling connector KV specifically has only four, at most five, contacts and a permanent retaining ring SOSI with a threaded G2B, the thread being an M12 thread configured to fasten to the thread G2A of the insertion section STA of the lower sensor module USM. Furthermore, the coupling connector KV has an upper insertion section STA1 with a threaded G1B, configured to fasten to the thread G1A of the upper sensor module OSM.

[0155] In particular, users can replace the energy storage unit ES1 with another energy storage unit ES2 by removing the housing cover KG1, and more specifically, with another battery BA. This energy storage unit can also have an additional capacitor ZK, resulting in a longer structure.

[0156] Furthermore, the wireless circuit board FP can be replaced, and thus the wireless standard can be changed, without altering the measurement position, the upper sensor module OSM, or the entire wireless sensor module FSM, including the lower sensor module USM, or detaching it from the process P.

[0157] Figure 9A This paper illustrates a possible embodiment of the wireless sensor module FSM according to the present invention using two connection protocols P1 and P2 to transmit measurement values ​​or communicate in an application environment.

[0158] Here, the upper sensor module OSM connects to the receiving station GW1 via the first connection protocol P1 for evaluating and displaying measurement values ​​on the terminal TM. This forms communication path UP1. Furthermore, the upper sensor module OSM connects to the user US's mobile terminal device MBT via the second connection protocol P2. This forms another communication path UP2.

[0159] Mobile terminal devices (MBTs) have a positioning system and a voice interface, through which users (US) can request measurement values ​​via voice and dictation services, for example.

[0160] In this scenario, when approaching a wireless sensor FS, even if reduced to a local space or activity radius, information can still be output through available devices.

[0161] Therefore, communication with the mobile terminal device MBT is conducted via the second protocol P2, particularly via a mobile network or the Internet IN, or via GSM services using 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 JSON file.

[0162] Therefore, communication paths UP1 and UP2 are formed, through which sensor data is redundantly sent to different receivers, especially through different transmission types.

[0163] Figure 9B A possible embodiment of the wireless sensor module FSM according to the invention in another application environment in building G is shown.

[0164] The measurements of the information and wireless sensor FS can be triggered on the one hand by local proximity and / or distance reduction, and on the other hand, if a threshold is exceeded during measurement, it can be triggered by a threshold stored in the wireless sensor FSM.

[0165] In this scenario, the proximity of the mobile terminal device (MBT) to the wireless sensor module (FSM) can also be achieved via a satellite-based positioning system (GPS). The location of one or more wireless sensors (FS or S) is initially determined during configuration and further determined by the associated mobile terminal device (MBT) during configuration, and stored in a database (DB) for location evaluation of the wireless sensors (FS or S). Therefore, in particular, it is possible to perform comparisons against such a database (DB) on demand by all devices within the requested available operational radius, without requiring each wireless sensor (FS) to have its own satellite-based positioning system (GPS).
