Therefore, the research and development of intelligent car guide control system has the extremely vital significance. This system uses STC89C51 as the core control chip, design and make a new electric sensor detection by infrared sensor information, infrared flame path of intelligent tracing test fire extinguishing car. The system is posed of singlechip microputer control module, tracing sensor module, drive motor module, ignition sensor module, fan module, power supply module. The practical application indicates that the car can be in a specially designed field on fire, to realize the independent found autonomous recognition route, independent sources and marching close to the fire extinguishing, finally plete task.
