[0002] Photovoltaic power stations occupy a large area and have many photovoltaic modules. Cleaning robots are installed on photovoltaic panels to clean photovoltaic panels and complete specific panel inspections. The robot is connected to the control platform through a data network and completes the corresponding operations according to the set program or the instructions received from the platform. It has a high degree of automation and unmanned operation, but the functions of the robot are limited. The power station still needs manual inspections. During manual inspections, if one or several cleaning robots need to be controlled to perform corresponding tasks, the inspection personnel need to log in to the platform through an electronic terminal to issue instructions to the robot. The outdoor environment is harsh and the maintenance personnel have a variety of equipment. In this case, it is inconvenient and unsafe to operate the electronic equipment to control the cleaning robot. Therefore, a convenient control method for the cleaning robot is needed to facilitate the maintenance personnel to control it. Summary of the invention

[0079] This embodiment provides a cleaning robot maintenance system based on the above embodiment.

[0080] The central control unit 60 is further used to identify whether the received light wave signal or the sound wave signal contains the valid cleaning instruction or the valid maintenance instruction, and monitor whether the cleaning robot 10 completes the cleaning task or the maintenance task, and when the cleaning task or the maintenance task is completed and the sound wave signal / the light wave signal is not identified to contain a valid maintenance instruction or a valid cleaning instruction, send a standby instruction to the cleaning robot 10;

[0084] This embodiment provides a cleaning robot maintenance system based on the above embodiment.

[0085] The central control unit 60 further includes a data storage device 61, wherein the data storage device 61 is used to store the voiceprint of the authorized operator and the legal light wave signal conditions, wherein the legal light wave signal conditions include the optical frequency range / optical wavelength range of the legal light wave signal;

[0093] In one embodiment, the reference specification Figure 2 The present invention provides a control method for a cleaning robot maintenance system, comprising:

[0094] When the S110 cleaning robot and photovoltaic bracket controller are performing cleaning tasks or standby tasks, the central control unit identifies the sound wave signals received by the sound control unit, identifies the light wave signals received by the light control unit, and identifies the instructions issued by the platform.

[0095] Step S110 monitors the sound and light waves around the cleaning robot in real time, and detects in real time whether there are any instructions issued by the platform.

[0096] S111 determines whether it is recognized that the sound wave signal / the light wave signal / the instruction issued by the platform contains a valid maintenance instruction.

[0097] Step S111 detects whether maintenance personnel have issued instructions to the cleaning robot through light waves, sound waves or platforms. When detecting sound waves, it is also possible to detect whether the sound wave signal contains the ID number of the cleaning robot; if the ID number of the cleaning robot is detected, a maintenance control signal is sent to the cleaning robot with the corresponding ID number according to the ID number of the cleaning robot identified. Because the sound wave has a wide range of influence, the above method can effectively avoid the misoperation of other cleaning robots within the range of influence of the sound wave.

[0098] S112 When it is recognized that the sound wave signal / the light wave signal / the instruction issued by the platform contains a valid maintenance instruction, the central control unit sends a maintenance control signal to the cleaning robot and the photovoltaic bracket controller. The maintenance control signal is pre-stored in the central control unit or sent to the central control unit by the platform in real time.

[0099] Step S112 is to send a maintenance control signal to the cleaning robot and the photovoltaic support controller when the central control unit recognizes the maintenance instruction.

[0100] S113 determines whether the cleaning robot and the photovoltaic support controller receive the effective maintenance instruction;

[0101] S114 When the cleaning robot and the photovoltaic bracket controller receive the effective maintenance instruction, the cleaning robot and the photovoltaic bracket controller respectively complete the maintenance task of the cleaning robot and the first control task of the photovoltaic bracket according to the maintenance control signal, and the first control task is used to control the photovoltaic bracket to complete the photovoltaic bracket maintenance angle adjustment.

[0102] Step S113 and step S114 are to perform maintenance tasks on the cleaning robot and the first control task on the photovoltaic bracket controller according to the maintenance control signal issued by the central control unit. Specifically, when the cleaning robot performs maintenance tasks, the photovoltaic bracket is adjusted to a suitable maintenance angle through the maintenance control signal, and the cleaning robot is controlled to move so that maintenance personnel can check whether there is any problem with the robot from multiple angles; when the photovoltaic bracket is being repaired, the cleaning robot and the photovoltaic bracket are controlled to be stationary through the maintenance control signal to ensure the safety of the maintenance personnel.

[0103] This embodiment is based on the previous embodiment. Figure 3 , provides a control method for a cleaning robot maintenance system, comprising:

[0104] When the cleaning robot and the photovoltaic support controller are performing standby tasks or maintenance tasks, the central control unit identifies the sound wave signal received by the sound control unit, identifies the light wave signal received by the light control unit, and identifies the instructions issued by the platform;

[0105] When it is recognized that the sound wave signal / the light wave signal / the instruction issued by the platform contains a valid cleaning instruction, the central control unit sends a cleaning control signal to the cleaning robot and the photovoltaic support controller;

[0106] The cleaning robot and the photovoltaic bracket controller respectively complete the cleaning task of the cleaning robot and the second control task of the photovoltaic bracket according to the received cleaning control signal, and the second control task is used to control the photovoltaic bracket to complete the cleaning angle adjustment of the photovoltaic bracket.

[0107] This embodiment sends cleaning instructions and cleaning control signals through the voice control unit / light control unit / platform, so that when the cleaning robot is in standby mode before maintenance, the maintenance personnel can quickly adjust the angle of the photovoltaic panel to a suitable cleaning angle through the cleaning control signal, and then start the cleaning robot to clean the photovoltaic panel, so as to observe whether the cleaning robot has any faults, thereby providing convenience for maintenance personnel.

[0108] This embodiment is based on the above embodiment. Figure 3 , provides a control method for a cleaning robot maintenance system, comprising:

[0109] When the cleaning robot and the photovoltaic bracket controller perform cleaning tasks or maintenance tasks, the central control unit identifies the sound wave signal received by the sound control unit, identifies the light wave signal received by the light control unit, and identifies the instructions issued by the platform;

[0110] When the cleaning task or maintenance task is completed, and the sound wave signal / the light wave signal / the instruction issued by the platform does not identify that it contains the valid maintenance instruction or the valid cleaning instruction, the central control unit sends a standby instruction to the cleaning robot and the photovoltaic bracket controller;

[0111] The cleaning robot and the photovoltaic support controller receive the standby instruction and execute the standby task.

[0112] In this embodiment, after the cleaning robot completes the maintenance task or the cleaning task, the cleaning robot and the photovoltaic support controller are controlled to enter the standby state, which can avoid the energy waste caused by the cleaning robot and the photovoltaic support controller being in the working state for a long time.

[0113] This embodiment is based on the above embodiment. Figure 4 , a control method for a cleaning robot maintenance system is provided, wherein in step S112, when it is recognized that the sound wave signal contains a valid maintenance instruction, the central control unit sends a maintenance control signal to the cleaning robot and the photovoltaic support controller, including:

[0114] The sound wave signal is transmitted to the central control unit, and the central control unit performs noise reduction on the sound wave signal by a noise reduction algorithm to obtain a denoised sound wave signal;

[0115] Matching the noise-removed wave signal with the sound wave signal in the storage medium inside the central control unit to determine whether the noise-removed wave signal has permission;

[0116] When the noise-removed wave signal is authorized and contains a valid maintenance instruction, the central control unit sends the maintenance control signal to the cleaning robot and the photovoltaic bracket controller.

[0117] This embodiment adds a function to determine whether the sound wave is a legitimate voiceprint, thereby avoiding safety hazards caused by other non-maintenance personnel controlling the cleaning robot and photovoltaic bracket through sound waves, and improves the accuracy of the voice control unit in identifying the sound waves emitted by maintenance personnel through a noise reduction algorithm.
