[0043] refer to Figure 1 As shown, during operation, the data of the device / sensor is collected and transmitted to the system of the host computer through the present invention. The present invention and the device / sensor can transmit data through a wired connection, and correspondingly, the present invention and the device / sensor can also transmit data through a wireless connection through the wireless module provided by the device / sensor.

[0044] In this embodiment, the integrated wireless experimental data transmission device provided by the present invention is integrated in the device housing and includes:

[0045] The microcontroller unit adopts MCU, and its integrated ADC / DAC module can perform the acquisition and output of digital signals and analog signals according to the needs. It receives the data from the I / O interface module, performs data preprocessing, data calibration, data conversion, data error detection and correction on the received experimental equipment or sensor acquisition data, and then sends the data to the host computer through the wireless communication module; and sends the received control instructions to the experimental equipment or sensor for execution through the I / O interface module;

[0046] Data preprocessing includes: conditioning the raw signal output by the experimental device or sensor, and converting the data into a standard format that can be processed by the microcontroller unit according to the output type of the experimental device or sensor;

[0047] Data calibration includes: calibrating the data collected by experimental equipment or sensors using a predetermined calibration algorithm to eliminate the errors of the experimental equipment or sensors; and adjusting the data collected by the experimental equipment or sensors according to known reference values or calibration data.

[0048] Data conversion includes: converting the data collected by experimental equipment or sensors into standard or user-specified units according to application requirements; and adjusting the data to a specified range.

[0049] Data error detection and correction includes: generating a data check code for error detection and performing error correction coding before the data is transmitted to the host computer.

[0050] The wireless communication module uses a WIFI module, which wirelessly transmits data based on the TCP protocol.

[0051] The I / O interface module is used to receive the data collected by experimental equipment or sensors and send it to the microcontroller unit.

[0052] The I / O interface module has multiple digital inputs, multiple digital outputs, multiple analog inputs, and multiple analog outputs.

[0053] The digital input of the I / O interface module supports switch quantity signals, and the digital output supports relay drive.

[0054] The analog input supports 0 - 10V voltage signals, and the analog output supports 4 - 20mA current signals.

[0055] Exemplarily, the interfaces of the I / O interface module at least include: wet contact, dry contact, DO power-on state, RS485 serial port, RS232 serial port, level counting interface, pulse valid state interface, and pulse counting interface.

[0056] Wet contact: The input voltage of the DI and DI.COM terminals. When the detected input voltage is within the range of 3 - 30VDC, the DI point value is 1; when the detected input voltage is within the range of 0 - 1VDC, the value of DI is 0.

[0057] Dry contact: Short-circuit DI and DI.GND, the DI point value is 1; disconnect the connection, the DI point value is 0.

[0058] DO power-on state indicates the state of the relay when the IO device has just been powered on and has not received an external control command. Writing a value of 0 indicates that COM and DO are disconnected when the IO device has just been powered on, and writing a value of 1 indicates that COM and NO are conducting when it has just been powered on.

[0059] RS485 Cascade: It has the function of converting 1-way RS485 to Ethernet communication. When a device using the Modbus RTU protocol is connected to the RS485 interface of the IO device, the host computer can access this Modbus RTU device using the Modbus TCP protocol. When accessing this Modbus RTU device, the function codes and register addresses used in the Modbus TCP protocol are the same as those of the original Modbus RTU device.

[0060] Pulse Counting: Positive / negative pulse valid status, DI positive / negative pulse counting;

[0061] DI Positive / Negative Pulse Status: Indicates the current input pulse status. When the switch is off, the value of the corresponding positive pulse status register is set to 1. When the switch is on, the value of the corresponding negative pulse register is set to 1. Writing a value of 0 clears the detected pulse status, and writing other values is invalid. DI Positive / Negative Pulse Counting: The number of positive / negative pulse changes, detecting the number of pulse changes. An initial value can be written, and after writing, it can count from the initial value to the maximum value of 65535. After reaching the maximum value, it starts counting from 0 again (range 0 to 65535).

[0062] Level Counting: Level change counting: The sum of the number of positive / negative pulse changes. An initial value can be written, and after writing, it can count from the initial value to the maximum value of 65535. After reaching the maximum value, it starts counting from 0 again.
