[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0029] like Figure 1-2As shown, this utility model provides an automatic photovoltaic panel cleaning robot, including a cleaning robot body 1. A cleaning component 2 is provided on the front of the cleaning robot body 1. A control device 3 is provided on the top of the cleaning robot body 1. Collision sensors 4 and infrared ranging sensors 5 are respectively provided on the four sides of the cleaning robot body 1. The collision sensors 4 are used to detect obstacles, and the infrared ranging sensors 5 send the detected data to the control device 3 for path planning. A suction cup component 6 is provided directly below the cleaning robot body 1. The control device 3 includes a mother board and a daughter board. A main controller is provided on the daughter board, and an information acquisition card, a motion control module, a speed detection module, and a wireless communication module are provided on the mother board. The daughter board is connected to the mother board via pins and sockets. The information acquisition card, motion control module, speed detection module, and wireless communication module are all electrically connected to the main controller. The collision sensors 4 and infrared ranging sensors 5 are both electrically connected to the main controller via the information acquisition card. The main controller is connected to the cleaning component 2 and the suction cup component 3 via the motion control module.
[0030] Specifically, the motion control module uses the MC33886 as the motor drive chip and adjusts the speed of the motor according to the duty cycle of the signal sent by the main chip. At the same time, the speed detection module detects the speed to complete closed-loop control.
[0031] Specifically, the speed detection module uses an encoder.
[0032] Specifically, the cleaning robot body 1 has wheels 7 on its lower part. The wheels 7 adopt a four-wheel structure, with the front and rear wheels being omnidirectional wheels 8 and the left and right wheels being drive wheels 9. Each drive wheel 9 is equipped with a drive motor, and the steering of the vehicle body is achieved by controlling the speed difference between the left and right wheels.
[0033] Specifically, the infrared ranging sensor 5 is a GP2D12.
[0034] Specifically, the control device 3 is connected to the remote monitoring center 10 via a wireless communication module. The remote monitoring center includes a host computer and a server.
[0035] Specifically, the wireless communication module adopts a 4G / 5G wireless network communication module.
[0036] like Figure 4 As shown, the main controller adopts a single-chip microcomputer minimum system, including a single-chip microcomputer, a power interface, a clock circuit, a reset circuit, and an EEPROM. The power interface, clock circuit, reset circuit, and EEPROM are all connected to the single-chip microcomputer.

[0038] Specifically, an amplification circuit, a filtering circuit, and an AD converter are provided between the collision sensor, the infrared ranging sensor, and the information acquisition card to amplify the signal and filter out interference.
[0039] In operation, this invention uses a collision sensor to detect obstacles around the robot, such as the position of edges, while simultaneously using an infrared range sensor to detect the distance to these obstacles. This data is then sent to the main controller, which uses the received data to plan the path, thereby controlling the robot's direction and speed.
[0040] The wheel body of this utility model adopts a four-wheel structure, with the two left and right wheels being drive wheels and the two front and rear swivel wheels providing support, such as... Figure 3 As shown, two independent drive motors are installed on the left and right wheels of the robot, respectively. The steering of the robot is achieved by controlling the speed difference between the left and right wheels. The control is simple and easy to implement, and it can easily realize the robot's functions of moving forward, turning left, turning right, moving backward, turning around, and rotating in place.
[0041] This system employs two-wheel differential control, thus requiring the control of two motors. Therefore, this invention uses four microcontrollers connected in parallel to improve current drive capability and reduce microcontroller heat generation. The microcontroller's PWM interface outputs PWM signals. To isolate the control and power sections, all PWM signals are isolated via optocoupler isolation modules. The isolated signals are then sent to the microcontroller. In this invention, a 6N137 is used for isolation. Figure 5 As shown.
[0042] The suction cup assembly of this invention is used to attach a robot to a photovoltaic panel and allow it to move up and down along a direction perpendicular to the surface of the photovoltaic panel. The suction cup assembly used in this invention is an existing product.
[0043] This invention can also install an image acquisition device on top of the robot and send the images to a remote monitoring center via a wireless network. The remote monitoring center can view the working process in real time, making it easier to identify problems and handle them promptly.
[0044] It should be noted that all components used in this utility model are existing products in the field and are not limited to specific models. The connection relationship between the components is also a conventional method in the field, as long as data transmission can be achieved.
