Abstract

The invention provides a thermal power generating unit coal conveying belt intelligent inspection device and method. The thermal power generating unit coal conveying belt intelligent inspection devicecomprises a dual-spectrum camera, a thermal infrared imager, a pulverized coal concentration detector, a sound pickup and a core controller, and the core controller is connected with the dual-spectrum camera, the thermal infrared imager, the pulverized coal concentration detector and the sound pickup; the system works in a non-contact monitoring mode, normal coaling of a coal conveying belt is not affected, meanwhile, data analysis and processing are matched, all-dimensional dead-corner-free coverage of the coal conveying belt is achieved, fault points are accurately positioned, the system structure is simple, and the operation cost is low.

Description

technical field [0001] The invention relates to the technical field of automatic control of thermal power plants, in particular to an intelligent inspection device and method for a coal conveying belt of a thermal power unit. Background technique [0002] The coal handling system of a thermal power station is the basis for ensuring the stable operation of the unit. If the coal handling system is not in stable operation, it may cause the generator set to shut down at any time, causing huge damage to power production. Coal is the raw material for electric power production, and the coal is safely sent to the boiler for burning through the coal conveyor belt, so that the thermal energy can be continuously converted into electric energy. If the coal delivery system cannot stably deliver coal to the coal bunker of the boiler, the boiler may shut down due to lack of fuel supply. Thermal power units consume a huge amount of coal, so the coal yards are built in locations with conven...
