[0028] In order to make the content of the utility model more easily be clearly understood, the utility model is further explained in detail below according to specific embodiments and in conjunction with the drawings.
[0029] As shown in Figure 1 The utility model provides a kind of intelligent cleaning camera for mine, it includes MCU module, motor drive module, brushless motor, wiper, positioning assembly and camera module.
[0030] As shown in Figure 1 The input end of the motor drive module of the utility model is connected with MCU module, and the output end of the motor drive module is connected with brushless motor. Wiper is fixedly connected with the motor shaft of brushless motor, and brushless motor is used to drive wiper to rotate, and wiper is used to clean lens glass. When it is needed to clean lens glass, MCU module drives brushless motor to rotate by motor drive module, and brushless motor drives wiper to rotate, and cleaning is carried out. As shown in Figure 2 The MCU module of the utility model adopts single-chip microcomputer U8, and the model of single-chip microcomputer U8 is ESP32-WROVER-IE-N16R8. As shown in Figure 3 The motor drive module of the utility model adopts motor drive chip U12, and the model is DRV11873PWPR.
[0031] As shown in Figure 1 The positioning assembly of the utility model is connected with MCU module, and positioning assembly is used to detect the rotating position of wiper. Specifically: as shown in Figure 4As shown, the positioning component includes a motor magnetic encoder positioning module and a magnet. The magnet is mounted on the motor shaft of the brushless motor. The motor magnetic encoder positioning module is used to detect the position of the motor shaft based on the position of the magnet on the motor shaft. The motor magnetic encoder positioning module uses a brushless motor encoder, a measurement technology widely used in brushless motor systems. It can provide real-time feedback of the motor's position and speed information, providing accurate and reliable control for the brushless motor system. The brushless motor encoder measures position and speed by detecting physical marks on the motor rotor. These physical marks are typically composed of magnets or photoelectric sensors; in this embodiment, magnets are preferred. An encoder disk can be formed around the motor rotor. The marks on the encoder disk change position according to the rotor's movement, and the encoder calculates the motor's position and speed by detecting changes in the mark positions. The encoder determines the motor's current position based on the position of the magnet on the motor shaft. If the wipers are manually moved or pulled, the MCU module will control the motor to reset.
[0032] like Figure 1 As shown, the camera module in this embodiment is used to capture images from underground. Figure 5 As shown, the camera module in this embodiment is model DS-2ZMN0407.

Figure 7 As shown, in this embodiment, the power amplifier module is connected to the interface of the camera module, and the power amplifier module is used for communication between the host computer and the underground site.
[0033] like Figure 1 As shown, the intelligent mining cleaning camera in this embodiment is also equipped with a supplementary lighting module. This module is connected to the MCU module and is used to provide supplementary lighting for the camera module. Figure 8 As shown, the supplementary lighting module in this embodiment includes a photoresistor LDR, an enable circuit, and a lighting circuit. The photoresistor is connected to the enable circuit, which in turn is connected to the lighting circuit. The photoresistor senses the ambient light intensity, the enable circuit controls the lighting circuit to turn on and off, and the lighting circuit provides supplementary lighting. When the photoresistor LDR senses that the ambient light is too low, the collector (C) of transistor Q1 sends an enable signal to pin 1 of the LED driver chip U2 in the lighting circuit. The LED driver chip U2 then drives the LED to light up, providing supplementary lighting.
[0034] like Figure 1As shown, the intelligent mining cleaning camera in this embodiment is also equipped with an RS485 communication module. The RS485 communication module is connected to the MCU module, and the MCU module communicates with the host computer through the RS485 communication module.
