Design of Intelligent Flushing System for Cable Trays in Coal Transportation System Based on Internet of Things
In response to the issues of excessive dust in the coal conveying system of China Energy Group Suqian Power Generation Co.,Ltd.,as well as the accumulation of dust in cable trays and boxes,which can easily lead to spontaneous combustion,this paper proposes an intelligent flushing system for cable bridges in the coal conveying system.The system utilizes Lora wireless temperature sensors from the Internet of Things(IoT)to detect the cable temperature within the cable trays and boxes.Communication control is achieved through the Modbus protocol with the PLC in the water flushing control cabinet,enabling automatic flushing when the cable temperature exceeds a preset threshold,as well as autonomous flushing functions.This system realizes intelligent sensing and fully automatic control from water supply to the completion of flushing,achieving excellent flushing results.Regular and effective cleaning of coal and dust accumulation in cable trays and boxes effectively reduces the occurrence probability of cable overheating and spontaneous combustion caused by the accumulation.
