Abstract:

Traditional artificial security patrol system is restricted by human factors, the patrol route, time, frequency, and the density is not reasonable. We design a car which has multisensor such as flame sensor, ultrasonic sensor, light sensor and so on. It uses freescale main controller and auxiliary controller which coordinate with each other to complete tracking and obstacle avoidance, low battery detection, temperature acquisition, smoke alarm, video transmission, intelligent control of motor speed and accurate positioning and so on. Patrol car uses PC for remote control and uses the real-time transmission image to test the security target. From the experiment test we know that the cars maximum error is 3%, so its intelligent patrol effect can meet the development requirements of the current requirement, and the small form, full functions and strong practicability all shows that it has a broad market application prospect.

Key words: security, patrol car, sensor system, remote monitoring and control, real-time communication
