摘要

 磁力啟動器是煤礦井下生產系統中的關鍵設備，本課題所研究的礦用磁力啟動器智能監控系統，以微芯公司生產的PIC16F877A單片機為控制核心，對電機起動、停止進行智能化控制，同時對各種故障進行保護監控。本系統具有保護、控制、測量、顯示、整定、通訊等功能，同時實現漏電閉鎖、短路、過載、斷相、欠壓、過壓等各種保護，并且采用液晶顯示器對運行情況及故障情況進行顯示，還設有故障查詢系統和通訊系統。因此本裝置可以大大提高故障檢修率，生產效率，節省大量的人力物力等，也使煤礦井下的電氣自動化水平得到較大提高。另外，本文也對妨礙系統正常運行的各種干擾信號及其抗干擾措施也進行了分析，研究。
 本文重點闡述了智能監控裝置的設計思想，工作原理，硬件構成等，討論了各種保護功能以及干擾信號的來源及其防治措施。

ABSTRACT

 Magnetism switch is the key equipment in coal mining system，the coal mining magnetism switch intelligent monitor system studied in this paper takes the PIC16F877A micro-controller as its control core, intelligently controlling the motor starting and suspending ,at the same time protecting and monitoring all kinds of troubles. The system has many functions such as protection, control, measuring, display, setting, self-diagnosis and communication and so on, the device also has protective steps of leakage locking, short-circuit, overload, phase-failure, under-voltage, over-voltage and so on, and it also could display operation and fault complexion using liquid crystal display and it also could have the system for inquiring about fault and communication. So the device could largely improve the rate of trouble shooting, manufacture efficiency, and save lots of persons and materials and so on .it also largely improves the electrical automatization level in coal system. In addition, the paper also analyses and studies all kinds of interference signals preventing the system from regular operation.
 The paper concentrates on the intelligent monitor device’s design thoughts, operation principles ，hardware constitutions and so on, discusses all kinds of protection functions, the cause of interference signals and treatment measures.
 The key words: PIC16F877A micro-controller；Intelligent monitor system；Protection；Interference
