Design And Study Of The Security Surveyed System For Preventing Mislead To Stage Loader And Some Other Dangerous

Considering the need of safety in the coal production ,The people in the conveyor transfer machine of fully mechanized coal working face and such dangerous places as goaf safety monitoring system is designed .The application of passive infrared probe-heat dispelled electricity sensor make the system more advanced.Unique people-positioned and motion relative position the matching algorithm acts out people positioned and tracked and also can stop running.The eleetrocircuit designe of infared wireless communication acts out infared digital gain adjusted.The function has unique advantage for the people who can't go up and down easily to adjust parameter.The design of study function lowers the effects of the environmental noise on the output signals and can also avoid wrong alarming.Because the system has unique automatic monitoring and stopping mechanism,the middle and small coal mines can still use it before the TK200 was used.The system can be not only used in large-size machines of coal mine,but also used in other similar equipments.The system will have been applied vastly in many fields and have a vast prospect.
