Mine Environmental Safety Monitoring And Control System Experimental Device

A experiment equipment of mine circumstance inspected and controled system is designed and come true. It is a model instrument abstracted according to a actual and all-purpose mine circumstance inspected and controled system. The gas consistence, the temperature and ventilation status mine underground etc. can be factually demonstrate and visualize by the experiment equipment. So the experiment model instrument function is very important in mine security education. The item of developing the experiment equipment of mine circumstance inspected and controled system comes from acrual require. a question for discussion is drafted by myself.The experiment equipme system is composed of two parts.One is called main stop which there is a IBM-PC system. The PC have a dynamic interfase used to show dates, analysedate dates ,dispose dates and output the results dates. In the dynamic interfase, some paraments about the gas consistence, the temperature and ventilation status mine underground can be adjusted and changed by input new numerical values .Another is conposed of seven work spots. A AT89C51 Single-Chip Microcomputer is a main hardware in every work spot .The job of paraments showed and paraments managed can be finished automatically in evry pont. Evre pont can work with main pont together . But one woek pont is not linked at first hand another pont .The experiment equipment productions have be producted now and used in some organization and coal corporation. we have requisitioned government help to generalize in future . we hope the equipment productions is volume-product for the future.The paper is diccussed main some problems: how to disige the experiment equipment's hardware and how to programe the system software, how to resove the problems in desige and development the system .such as paraments value exceeded and not communication in several computer system etc.
