Abstract:

To solve the problem of lacking of global monitoring device and collision warning device for domestic bridge-detection vehicle,we design and implement an intelligent monitoring system based on Android.The system uses real-time 3D model to simulate robot arm posture in realtime from tilt sensor, achieving  global monitoring.The system can also  build virtual obstacles based on actual situation,to simulate the collision between robot arm and obstacles vividly.If collision was detected,the system will trigger the alarm.Result shows that the system has reliable performance as well as strong practicability, it not only solve the problems of the traditional video surveillance can not reach the global monitoring, and also provides a reliable reference for avoiding obstacles by labour.
