Circuit control system for photovoltaic assembly cleaning detection robot

Abstract

The invention discloses a circuit control system for a photovoltaic assembly cleaning detection robot. The circuit control system is composed of a PLC control unit and an ARM control unit that is connected with the PLC control unit electrically and is capable of carrying out data transmission with the PLC control unit. The ARM control unit is electrically connected with the first communication module connected with a background monitoring system electrically and is capable of carrying out monitoring and backing up during program dispatching of the PLC control unit; the background monitoring system is able to carrying out monitoring and backing up during program dispatching of the ARM control unit. Therefore, the circuit control system of the robot becomes stable and reliable; and problemsof program dropping, program mixing, and data transmission interruption are solved. Feedback is carried out according to a current different in the circuit and rotating speeds of the two wheels are adjusted, so that a phenomenon that the wheel is stuck is avoided and thus smooth turning and crossing are realized. A determined position of a mark above a problem assembly is identified by using an infrared thermal imaging module and an NFC near-field communication module; and thus the problem assembly is identified quickly and the location is determined, so that the maintenance becomes convenient.

Description

Technical field [0001] The invention relates to the technical field of photovoltaic power generation panel cleaning, and in particular to a circuit control system for a photovoltaic module cleaning detection robot. Background technique [0002] With the rapid development of intelligent operation and maintenance of photovoltaic power plants, the types of photovoltaic module cleaning robots have also increased, but the circuit control system used in photovoltaic module cleaning robots is difficult to work in the outdoor environment for a long time. The current cleaning robots revolve around single-chip microcomputers. As the core control hardware development platform, this kind of control system uses "STC series" and other platforms as the control unit and relies on built-in program control. Although the price is low, the system has poor stability and low reliability, and is prone to program drop, program confusion, and Problems such as interruption of data transmission. [0003] It...
