In view of the problem that the existing conveyor belt detection device is not effective in detecting conveying problem of low reliability in harsh environments, longitudinal rip of belt, a new method based on on-line monitoring and inspection was presented in this thesis. By arranging the light curtain sensor below the conveyor belt, and continuously collecting the data through the light curtain sensor, the system can analyse multiple sets of collected data sing the delay interval algorithm and monitor the duration, movement direction and interval size that the lights of the light curtain sensor emitted has been continuously blocked. All these data helps detect if the conveyor belt has been tom. It is proved in the heat-engine plant C of Guangdong that the detection rate of the conveyor belt longitudinal tearing is above 95% , and the monitoring system can work normally in harsh environment and can be worthy of popularizing.

This article introduces each components of multifunctional road testing and measurement system and technical principle of each unit of the system briefly. According to these, the article analyses some problems and deficiency of road testing and measurement system in real application in home and abroad, and shows us corresponding method. Combinning with the development of computer, sensor technology and the practical necessary of industrial application, it puts forward that the focus direction of the multi-functional road testing and measurement system is the application of 3-D laser scanning technology which makes the high integration and multi-function of the system come in true.
