Coal conveying system in power plants is an accident-prone system. Its patrol task is important and heavy

and the patrol environment is bad. In order to reduce the labor intensity of operation and maintenance personnel

improve the efficiency of inspection

and enhance the safety of coal conveying system

an automatic inspection system of robot is designed and developed. The system uses robots instead of manual inspection of corridors

applies cameras and various detection instruments instead of various judgments of human beings

and realizes comprehensive management for the whole inspection system in the form of three-dimensional pictures. Finally

it can realize automatic inspection of the entire coal conveying corridor

and alarms automatically for overtemperature

abnormal sound

excessive dust

belt deviation and other phenomena in the inspection process

so as to realize the function of accident tracing and historical inquiry. The whole system has achieved demonstration application in power plants

and all functions have reached the expected goal. It provides practical experience and optimization direction for subsequent large-scale application.
