Video monitoring system for large maintenance machinery

Large railway maintenance machinery plays a significant role in ensuring the railway running safety. Video monitoring system for monitoring the process of maintenance and construction such as the tamping machine is an important research topic to achieve the goal of supervising the working state and working quality. A video monitoring system based on TMS320DM642 DSP, local network and GPRS is developed for large maintenance machinery. The overall design of the system is introduced firstly. Then the vehicle video data acquisition system and the vehicle video monitoring system are described in detail. Finally, the laboratory test and application results are given. The running results show that the monitoring system is stable and reliable.
