[0036] Example 1

[0037] This application embodiment illustrates a wireless data acquisition node module, including a data acquisition box 100, a circuit board 200, a connection terminal assembly 300, a sensor, a combination connector 500, a positioning connector 600, a power module 700, and a power display module 800. The circuit board 200 is installed inside the data acquisition box 100. The connection terminal assembly 300 is connected to the circuit board 200 inside the data acquisition box 100, and the sensor is connected to the connection terminal assembly 300 to transmit the information acquired by the sensor to the circuit board 200. The combination connector 500 is disposed on the data acquisition box 100 and used to connect to another wireless data acquisition node module. The positioning connector 600 is installed on the outside of the data acquisition box 100 for connection to a device that needs to acquire information. The power module 700 is disposed inside the data acquisition box 100 to connect to the circuit board 200 and / or the connection terminal assembly 300 and / or the sensor to provide power. The power display module 800 is connected to the power module 700 to display its remaining power, allowing the user to intuitively understand its status.

[0038] In this embodiment, the circuit board 200, the pin portion of the connection terminal assembly 300, and the power module 700 are installed inside the acquisition box 100 for centralized protection to prevent them from being interfered with by external factors. Information required by the user is collected by sensors and output to the circuit board 200 via the connection terminal assembly 300, where it is further processed. The combination connector 500 can combine multiple wireless acquisition node modules to achieve the acquisition and processing of various types of information, avoiding the phenomenon of overly singular information that can be collected. The positioning connector 600 can install the wireless acquisition node module of this embodiment on the required device or part to collect specified information, ensuring that this embodiment can maintain a stable connection with the required device or part when it is moving. The power module 700 can provide power to any electrical appliance in this embodiment. The power display module 800 allows users to easily and intuitively understand the remaining power of the power module 700 in real time, facilitating timely replenishment or replacement.

[0039] Optionally, the sensors include, but are not limited to, accelerometers, strain sensors, pressure sensors, load cells, torque and vibration sensors, magnetometers, 4-2 0mA sensors, RTD sensors, humidity sensors, displacement sensors, and thermocouples, etc.; specifically, for example, thermocouples (-210~1820℃) include types J, K, N, R, S, T, E, and B; RTDs (-200-850℃) include types PT-10, PT-50, PT-100, PT-200, PT-500, and PT-1000; thermistors (-40~150℃) include types 44004, 44033, 44005, 44030, 44006, 44031, 44007, 44034, 44008, 44032, and YSI-400; RPM (6~6000rpm) includes open-circuit circuits or level signals from Hall effect or other sources.

[0040] Optionally, the circuit board 200 may include, but is not limited to, a signal receiving module, a signal processing module, a signal output module, an offline buffer module, etc., wherein both the signal receiving and output modules may have wireless transmission capabilities.

[0041] In one optional implementation, after the circuit board 200 is powered on, the connection terminal assembly 300 needs to be connected and conductive with the sensor required by the user. Then, the wireless acquisition node needs to be matched with host computer software for real-time data acquisition and analysis. Through the control of the host computer software, real-time reading of digital signals can be achieved, with a data reading frequency range of 1–10240Hz, corresponding to a stable communication distance of up to 2km outdoors and 400m indoors. Simultaneously, through the configuration of the host computer software, the analog output of the sensor type acquired by the wireless acquisition node module can be realized, allowing the sensor data to be directly transmitted to independent data acquisition devices or a series of industrial devices connected to a PLC.

[0042] In one optional embodiment, the combined connector 500 includes a slot 510 formed on one side of the acquisition box 100, and a first magnetic attraction part 520 is provided at the bottom of each slot 510. In this embodiment, the connection with another wireless acquisition node module is achieved through the cooperation of the slot 510 and the first magnetic attraction part 520, making the entire connection structure more stable and reliable. Optionally, the slot 510 can restrict the horizontal movement of the other wireless acquisition node module, and the first magnetic attraction part 520 can lock its vertical movement. By restricting the horizontal movement of the other wireless acquisition node module connected to it by the slot 510, the first magnetic attraction part 520 only needs to overcome the force of vertical movement to fix it, reducing the requirement for magnetic attraction force.

[0043] In one alternative embodiment, the combined connector 500 is configured as two sets and respectively disposed on opposite sides of the acquisition box 100; a card block 900 is engaged in one of the slots 510 of the two sets of combined connectors 500, and a second magnetic suction part 910 is provided on the side of the card block 900 facing the bottom of the slot 510.

[0044] In this embodiment, a card block 900 is engaged in one of the slots 510 of the two sets of combined connectors 500, while the other slot 510 does not have a card block 900. This achieves the following effects: for example, the card block 900 of the first wireless acquisition node module is engaged in the slot 510 of the second wireless acquisition node module, thereby enabling the wireless acquisition node modules to be connected to each other in pairs. It should be understood that the number of wireless acquisition node modules can be set according to the actual number of sensors required. The second magnetic part 910 can magnetically engage with the first magnetic part 520, thereby improving the connection stability between the card block 900 and the slot 510. The magnetic arrangement also facilitates the connection and disassembly of the two.

[0045] In one optional embodiment, a third magnetic attraction part 920 is provided on the side of the card block 900 away from the bottom of the card slot 510; the third magnetic attraction part 920 can be attracted to the first magnetic attraction part 520 of another wireless node acquisition module; for example, when two wireless node acquisition modules are connected, the first magnetic attraction part 520 on the first wireless node acquisition module is attracted to the second magnetic attraction part 910 on the card block 900, and the first magnetic attraction part 520 on the second wireless node acquisition module is attracted to the third magnetic attraction part 920 on the card block 900; through the cooperation of the two sets of magnetic attraction connections, the effect of ensuring a stable connection between two adjacent wireless node acquisition modules is achieved.

[0046] In one alternative embodiment, the slot 510 is configured as a dovetail groove, and the locking block 900 is configured to simultaneously engage two sets of dovetail grooves; for example... Figure 5 As shown, the dovetail groove design makes it easy for the card block 900 to be inserted into the card slot 510, while preventing the card block 900 from moving horizontally. This allows the magnetic suction part to overcome the force of the vertical movement of the wireless acquisition node module, which is beneficial to further ensure a stable connection between two adjacent wireless node acquisition modules. The card block 900 can simultaneously engage two sets of dovetail grooves, meaning that the card block 900 can simultaneously engage the card slots 510 of two adjacent wireless node acquisition modules, thus tightly connecting the two.

[0047] In one alternative implementation, the slot 510 may also be circular, square, or irregularly shaped, etc.

[0048] In one optional embodiment, the positioning connector 600 is configured as an L-shaped connector, the vertical end of which is connected to the side wall of the acquisition box 100; a connection hole 610 is provided on the horizontal end of the L-shaped connector; the wireless acquisition node module is connected to the component to be acquired by screwing a screw into the connection hole 610; optionally, the vertical end of the L-shaped connector is configured as a locking structure that is inserted into the groove of the side wall of the acquisition box 100 and then fixed by screws, so that the connection is more secure.

[0049] In one optional embodiment, the L-shaped connecting blocks are configured in two sets, with the two sets of L-shaped connecting blocks positioned on opposite sides of the acquisition box 100; the line connecting the two sets of L-shaped connecting blocks is perpendicular to the line connecting the two sets of combined connectors 500.

[0050] In this embodiment, since the data acquisition box 100 has four sides, two sets of L-shaped connecting blocks are respectively disposed on opposite sides of the data acquisition box 100; and two sets of combined connecting parts 500 are respectively disposed on the other opposite sides of the data acquisition box 100. In this way, the purpose of not conflicting or interfering with each other when multiple wireless data acquisition node modules are combined or when the wireless data acquisition node module itself is installed is achieved, and the balanced arrangement of connection points can help the installation stability of this embodiment.

[0051] In one optional embodiment, the connection terminal assembly 300 includes terminal pins 310 and terminal body 320. The terminal pins 310 extend into the acquisition box 100 and are connected to the circuit board 200. The terminal body 320 protrudes from the top of the acquisition box 100 and is provided with a mounting position 321. A clamping member 322 is provided on the upper side of the mounting position 321.

[0052] In this embodiment, the terminal pin 310 extends into the data acquisition box 100 and connects to the circuit board 200, thus protecting the terminal pin 310. The mounting position 321 on the terminal body 320 protrudes outside the data acquisition box 100 for connecting the sensor (not shown), and the connecting part of the sensor is pressed by the clamping member 322 to prevent it from falling off. The connection and disassembly of the sensor are located outside the data acquisition box 100, which facilitates operation by the user.

[0053] In one optional implementation, a charging interface 130 is provided on the data acquisition box 100 to connect to a power module 700, which is a rechargeable battery. By setting the power module 700 to a rechargeable mode, the operation of disassembling the data acquisition box 100 to replace the battery can be reduced, making it more convenient and faster. Optionally, the charging interface 130 can be a magnetic charging head, USB charging, Type-C charging, etc.

[0054] In one optional implementation, a power display switch 140 is provided on the data collection box 100 and connected to the power display module 800, so that the remaining power can be displayed when needed and the power display can be turned off when it is not necessary to know the power.

[0055] In one alternative implementation, a marking component 150 is provided on the acquisition box 100, which can mark information such as the sensor of the wireless acquisition node module, such as model, function, etc.

[0056] In one optional embodiment, the collection box 100 includes a base 110 and a box cover 120 detachably connected to the base 110; the side wall of the base 110 is respectively provided with a combination connector 500 and a positioning connector 600.

[0057] In this embodiment, by integrating the combination connector 500 and the positioning connector 600 on the base 110, and making the base 110 and the cover 120 separate, the wireless acquisition node module is easy to assemble and disassemble, and it is more convenient to process only the base 110, a small part, such as the slot 510.

[0058] Example 2

[0059] The wireless acquisition device includes at least two wireless acquisition node modules as described above, wherein the slot 510 of one wireless acquisition node module is engaged with the card block 900 of the other wireless acquisition node module. It should be understood that there is no limit to the number of wireless acquisition node modules; the appropriate number of wireless acquisition node modules can be combined and connected according to actual needs.
