Rsearch and application of power intelligent monitoring system in Hanjiacun Coal Preparation Plant
In response to the problems of low operating economy and long system response time in the operation of the power equipment of Coal Preparation Branch of China Energy Baotou Energy Co.,Ltd.(hereinafter referred to as Hanjiacun Coal Preparation Plant),a power intelligent monitoring system for Hanjiacun Coal Preparation Plant was designed.The overall structure of the power intelligent monitoring system was introduced from background main station layer,communication compartment layer,and on-site equipment layer,and the functions of six modules of the system were elaborated.In terms of hardware design of the system,the 73 S169DT single-chip microcomputer is used as control core,and the microcontroller is embedded in the hardware circuit of power monitor;in terms of software design of the system,a data acquisition unit corresponding to the operation status of power equipment has been established,digital filters under causal and stability conditions are used to process the transmission channel signal of power monitoring data to determine whether there is any transmission abnormality in the power monitoring data of Hanjiacun Coal Preparation Plant,so as to achieve power monitoring of Hanjiacun Coal Preparation Plant.After the system design was completed,tests were conducted based on the operating characteristics of the power equipment in the coal preparation plant.The results showed that the system operated well and could effectively monitor the power equipment in the coal preparation plant.
