摘要

 在一些礦山的運輸過程中，由于操作人員的誤操作，導致不時都會發生誤停，或不停等事故，給礦山的安全生產帶來了嚴重的危害。
 本裝置是在原來的電機車操作基礎上實現電機車自動停車。它對電機車的運行速度進行動態顯示，當電機車進行預定區域并觸發電磁式位置觸發器, 位置接收器將觸發信號傳到單片機，單片機于是發出報警，并根據接收到的齒頻脈沖信號進行距離計算。當行車距離滿足設計要求時但車上工作人員沒有按下手動按扭，電機車就會以自動方式停車。單片機先就鎖定電機車速度，再根據鎖定速度進行停車控制，從而達到準確停車。
 為滿足運輸列車的多種需要，裝置設計應具備多項功能，但主要功能圍繞準確停車為主來完成安全保護功能。

Abstract

 In some areas of transport, because operators wrong control led to occur from time to time will mistakenly stopped, or keep accidents to the mines pose a serious safety hazard.
 The device is operated in the original train basis electrical vehicles automatically. Its operating speed electrical vehicle dynamics revealed that when a train go into planned regional and the location of the trigger electromagnetic sensors, location receivers will transmitted trigger signals to single-chip. Then single-chip issued warning, and in accordance with the received number of teeth frequency pulse signals to calculation. When travelling distance to meet design requirements, but the operator did not press the manual buttons, train will automatically way to the parking.
Single-chip locks the speed on the first, then under lock pace to control parking style, thus achieving accurate parking.
 To meet the diverse transportation needs of the train, devices should be designed with a number of functions, and the primary function mainly to the completion of the parking around the exact security protection functions.
 Key words: location trigger;gear pulse; 555 timer; AT89C51 single-chip; I/O expansion 8155
