摘要
系统是将煤源的煤炭处理成煤粉供给到原煤仓以备燃烧发电使用。设计中采用西门子CPU315-2DP担任主控单元,控制输煤系统的所有组成部分,采用PROFIBUS-DP通信方式通过硬件组态ET200M分布式I/O站点来实现分布式控制系统,分布控制地域分散的各种设备。在实现系统逆煤流顺序启动、顺煤流顺序停止、故障联锁停止、严重故障急停、自动配煤等功能的同时,解决了该类系统存在的落煤管容易堵塞、输送皮带容易撕裂和塌陷、输送皮带跑偏等问题。
The system is the source of coal into coal bunker pulverized coal which is supplied to the combustion power for use. Design using Siemens CPU315-2 DP as main control unit,controlled on all components of the coal handling system,through hardware configuration ET200 M distributed I/O site to realize the distributed control system based on PROFIBUS-DP communication and distributed control for geographical dispersion equipment. In the realization of the system against the coal flow sequence startup,in coal stream order stop,stop interlock failure,severe faults emergency stop,automatic blending function at the same time,solved the problems existed in the system,such as falls coal pipe is easy to plug;convey or belt is easy to tear and the collapse,the conveying belt deviation.
