The mainboard 12 is electrically connected to the human-computer interaction device 2 via the liquid crystal display module.

[0044] In this embodiment, the present invention collects data through a data acquisition module, processes it in a data processing circuit, and then inputs it into STM32F103. After passing through the ADC module of STM32F103, the analog signal is converted into a digital signal. Then, the collected digital signal is directly input through the I / O port of STM32F103, collected through an interrupt timer, and directly entered into the STM32F103 chip, and processed together with the analog signal converted into a digital quantity, the processed data is stored in the STM32F103 chip through a storage module for easy query and analysis, and displayed in real time on a human-computer interaction device.

[0046] In this embodiment, the signal measurement amplifier circuit: In order to meet various small signal states, a signal measurement amplifier circuit is used to achieve it. Its main principle is that the operational amplifier is measured through a differential circuit, and the amplification factor is changed by adjusting the resistor connected to the amplifier in the circuit. The amplifier circuit is as follows: Fig.12 shown.

[0047] Signal filtering and shaping circuit: Although the small signal is processed by the amplifier circuit, in actual measurement, it will be interfered by various magnetic fields, and the amplifier circuit itself will also produce various interferences. If it is directly processed by the STM32F103 microcontroller, it will cause serious distortion. Therefore, it is necessary to filter and shape the amplified signal. The specific circuit design is as follows: Fig.13 shown.

[0048] Sample and Hold: When using a single-channel ADC injection module to collect analog signals, the processed analog signal needs to be injected into the ADC module; when the input signal changes, the output signal must follow the changes of the input signal in real time, so the signal must pass through the sample and hold before it is transmitted to the ADC module; its main function is to perform interval sampling of the signal, and maintain the state at the end of the previous sampling during the interval between two samplings. The circuit design of the sample and hold is as follows: Fig.14 shown.

[0050] In this embodiment, in order to collect monitoring data more intuitively, the collected data needs to be uploaded to the PC of the control center, which also facilitates the computer networking and sharing of data; the MODBUS protocol adopts the RS485 communication method to carry out long-distance and high-speed transmission of power collection data; the present invention selects the isolated RS485 communication chip ADM483 with a maximum transmission rate of 500Kbps, and designs the circuit as follows Fig.15 As shown in the figure, the chip adopts a slew rate limited driver. The lower slew rate reduces the bit errors caused by improper terminal matching and connectors. The ADM2483 receiving input has a true fail-safe function. The driver also has a short-circuit current limit and can put the driver output into a high-impedance state through a thermal shutdown circuit to prevent excessive power loss.
