Design of the smart car for emergent disaster detection

A smart car is designed which can automatically go to the accident scene collecting the circumstance information of abrupt chemical disasters for making quick rescue plans. The combined GPS device and ultrasonic sensor navigation algorithm is proposed for automatic drive of the unpiloted car in respect that the poisonous and harmful air is hard to be close to. The hardware and software realization is given in detail. The spot situation detected by the carried sensors will be sent immediately to the decision-maker by the designed wireless communication device in the car. Experiments are done in the workshop, which show the correctness and feasibility of the design.
