Mine locomotive drivers are prone to fatigue driving and absent-minded operation,which is a major coal mine po-tential safety hazards in coal mine,so an alarm system for obstacle detection in front of mototive was designed. It has an impor-tant significance to coal mine safety. The key technology of this system is remote ranging. Therefore,the ultrasonic ranging tech-nology was selected in combination with environmental complexity in the coal mine. In order to realize the purpose of ultrasonic remote ranging,AR30 ultrasonic sensors made in AIRMAR Company were selected. A reasonable hardware circuit was designed by matching the performance parameters with each sensor,which can get and display an accurate distance value with the help of a series of software algorithms. When the distance is less than that of the audible and visual alarm,the driver is reminded with audible and visual alarm signals,which provides the driver with technical support to ensure driving safety.
