Abstract: In view of problems of single monitoring information, poor flexibility and complicated wiring existed in present monitoring system for mine safety, a mobile monitoring system for mine safety based on ARM was designed. The system uses environment parameter acquisition module and USB camera to collect on-site environmental information and video information, adopts S3C6410 processor to pack the collected data and transmits the data packets to upper computer for display by WiFi, so as to control the movement of the monitoring equipment. The system can real-timely monitor areas with inconvenience into or potentially dangerous for person.
