[0026] The preferred implementation manners of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0027] The present utility model provides a miniaturized wireless sensing array acquisition system, including a data acquisition unit 1, a processing unit 2, and a power supply module 11 for power supply.

[0028] The data acquisition unit 1 includes an acquisition module 14. The acquisition module 14 includes upper and lower layers of electrode materials. Each layer of the electrode material includes multiple strips. Among them, the upper - layer electrode material is arranged in rows, and the lower - layer electrode material is arranged in columns, so that the upper - layer electrode material and the lower - layer electrode material are staggered to form a number of intersection points. The acquisition module 14 includes two FPC connectors and a triode. The FPC connector is electrically connected to the collector of the triode through the traces on the circuit board to scan and acquire the sensing array by using the triode. Among them, the electrode material arranged in rows is electrically connected to one of the FPC connectors through an FPC cable.

[0029] The acquisition module 14 is electrically connected to the single - chip microcomputer control module 13 and transmits the scanned data to the single - chip microcomputer control module 13. The single - chip microcomputer control module 13 and the acquisition module 14 are arranged for two - way conduction. Among them, the electrode material arranged in columns is electrically connected to the other FPC connector through an FPC cable. This FPC connector is connected to a resistor through the traces on the circuit board, and the resistor is connected to the main control chip in the single - chip microcomputer control module 13.

[0030] The single-chip microcomputer control module 13 is set as a single-chip microcomputer controller, which includes a single-chip microcomputer and a crystal oscillator circuit. The model of the single-chip microcomputer is ATMEGA2560, and a program for driving the acquisition module 14 is stored in the single-chip microcomputer to drive the acquisition module 14 to scan and acquire the sensor array. The output end of the single-chip microcomputer control module 13 is electrically connected to the Bluetooth module 12. The single-chip microcomputer control module 13 transmits data unidirectionally to the Bluetooth module 12 based on the data of the acquisition module. The Bluetooth module 12 is wirelessly communicatively connected to the processing unit 2, that is, the Bluetooth module 12 wirelessly transmits the data of the single-chip microcomputer control module 13 to the processing unit 2, so as to transmit the data acquired by the acquisition module 14 to the processing unit 2 through the Bluetooth module 12.

[0031] The chip model used by the Bluetooth module 12 is CH9141K, and a piezoelectric ceramic antenna is adopted, which can reduce the volume of the Bluetooth module 12. Installing the Bluetooth module 12 can realize the wireless connection between the sensor and the data acquisition node, further simplify the deployment of the system, and reduce the complexity of wiring and connection.

[0032] The processing unit 2 includes a software control module 21. The software control module 21 uses Arduino IDE software, which is used to drive the triode in the acquisition module 14 to cyclically scan and acquire the sensor array. The Bluetooth module 12 is wirelessly communicatively connected to the software control module 21, so that the Bluetooth module can transmit the acquired data to the software control module 21 in a wireless transmission manner. The output end of the software control module 21 is electrically connected to the visualization module 22 to transmit the data after scanning and acquisition to the visualization module 22.

[0033] The visualization module 22 is set as a serial port monitor, which is associated with the serial port of the computer through the Bluetooth module 12. The serial port monitor can read the acquisition information of the acquisition module 14 and display it.

[0034] The power supply module 11 includes a battery and a voltage stabilizing chip. The battery can use a lithium battery or a button battery. The lithium battery is rechargeable and can be recycled. The button battery is small in size, light in weight and relatively low in price, and both can be used in this application. The voltage stabilizing chip filters out the low-frequency interference signals in the output voltages of the dry battery and the voltage stabilizing block through capacitors, and its output end is electrically connected to the input ends of the Bluetooth module 12, the single-chip microcomputer control module 13 and the acquisition module 14 respectively to provide power for them.

[0035] The data acquisition unit 1 is fixedly installed on a double-layer PCB board and double-sided surface-mounted, and is reasonably arranged to achieve a miniaturized PCB board design of 3CM×3.8CM.

[0036] Reference for the working process of components Figure 1, First, the power supply module 11 supplies power to the acquisition module 14, the single-chip microcomputer control module 13, and the Bluetooth module 12, enabling them to enter the working state. The single-chip microcomputer control module 13 drives the triode of the acquisition module 14 to scan and collect the sensing array, and transmits the data after scanning and collection to the software control module 21 through the Bluetooth module 12. Then, the software control module 21 transmits the data into the visualization module 22 and displays the data after scanning and collection.

[0037] System process reference Figure 2 , Initialize the system and the line scan. Then enter the loop statement that scans the number of lines and collects data through the number of columns, that is, initialize the acquisition scan of the electrode material arranged in rows, determine the scan position through the intersection of the row electrode material and the column electrode material, and then transmit the scanned data through the electrode material arranged in columns. When the array data is scanned in sequence, the data is sent to the visualization module 22 through the Bluetooth module 12, and then re-enter the row judgment and start the loop scan again, thus achieving the purpose of "row plus column" array data acquisition.

[0038] In summary, through the row and column arrangement, the system can effectively organize and manage a large number of sensors, improve the efficiency and coverage of data acquisition. The row and column arrangement has a compact design, which can make the system have a miniaturized design, relatively small volume, suitable for deployment in various scenarios with limited space, and improve the flexibility and deployability of the system.

[0039] Adopting wireless communication technology can achieve wireless connection between sensors and data acquisition nodes, simplify the system deployment and maintenance process, reduce the complexity of wiring and connection, and improve the scalability and reliability of the system.
