Problems solved by technology

[0002] The cleaning of dust on the surface of photovoltaic modules is an important task for the operation and maintenance of photovoltaic systems. In the past, most of the cleaning methods were manual wiping, which had high labor costs and low efficiency. In addition, for distributed photovoltaic arrays installed on the roof, the operation and maintenance of manual wiping This method will bring certain potential safety hazards. Therefore, domestic and foreign research institutions have launched research on photovoltaic module cleaning robots. Photovoltaic arrays with relatively uniform module sizes; in addition, most existing robots still use manual remote control for cleaning, which is less efficient and will bring certain safety hazards to operators

Embodiment 1

[0046] The present invention proposes an automatic operation and maintenance control strategy for a photovoltaic module cleaning robot, which is a cleaning robot such as figure 1 The crawler-type mobile robot shown is equipped with a roller brush cleaning device on the front side of the body. The hardware control system mainly includes a motor drive module, an edge signal detection unit, an attitude signal detection unit, and a positioning data acquisition unit. The automatic operation and maintenance control program is written by the controller to realize the automatic dust cleaning of the distributed photovoltaic power station on the roof.

[0047] The flow chart of the automatic operation and maintenance control strategy of the cleaning robot of the present invention is as follows figure 2 As shown, there are 5 links respectively, and their explanations are as follows:

[0048] (1) The information acquisition link is to obtain relevant external signals collected by the ro...

Embodiment 2

[0063] Embodiment 2 further designs the roller brush cleaning device and hardware control system of the cleaning robot on the basis of Embodiment 1, as follows:

[0064] The cleaning robot of the present invention is as figure 1 , Figure 13 as well as Figure 14 The crawler-type mobile robot shown is equipped with a roller brush cleaning device on the front side of the vehicle body. The roller brush cleaning device includes a roller brush motor 1, a left bearing seat 21, a right bearing seat 22, a main shaft 3, a left side plate 41, and a right side plate 41. Plate 42, hollow roller brush shaft 5, left U-shaped connector 61, right U-shaped connector 62, aluminum profile 7; the roller brush cleaning device fixes the left side plate 41 and the right side plate 42 respectively on the two ends of the aluminum profile 7, As the bearing frame of the roller brush cleaning device; the left bearing seat 21 and the right bearing seat 22 are respectively fixed on the outside of the le...

Abstract

The invention discloses an automatic operation and maintenance control method for a photovoltaic module cleaning robot. The automatic operation and maintenance control method sequentially includes five links: information acquisition link, movement mode set acquisition link, action switching control and trajectory adjustment link, boundary detection and The gap filtering link and the motor control link can realize the automatic dust cleaning of the roof distributed photovoltaic power station; the robot is a crawler mobile robot, and the front side of the body is equipped with a roller brush cleaning device; for the roof distributed power station, that is, the rectangular array, the component room The gap is 2 to 3 cm, and an automatic control strategy for the reentrant robot is proposed, which includes switching control of the action; detection of the array boundary to prevent the robot from falling; at the same time, it can also judge and filter the gap between components, thereby reducing Robot misjudgment of array boundaries. The beneficial effect of the invention is that it can realize the automatic dust cleaning of the distributed photovoltaic power station on the roof, and improve the operation and maintenance efficiency.
