Research And Development Of Vehicle Anti Theft Alarm Positioning System Based On Multi-sensor Information Fusion

With the continuous development of social economy and science and technology,people's living standard has been improved.More and more families to buy the cars.The cars have become a mainstream means of transport.However,while the convenience of the people to travel by the cars,the stolen situation is also increasing,cause the owners of the economic losses.Therefore,the installation of advanced anti-theft equipment on the car is essential.Automobile anti-theft technology has gone through four stages of development,they are mechanical development stage,electronic development stage,chip development stage and network development stage.According to the survey statistics,electronic anti-theft in our country used a lot.Now even the majority of cars are equipped with anti-theft devices,but they generally have the following shortcomings,they are no alarm function,high false alarm rate,can not remote automatic alarm,no vehicle location and so on.In view of the above shortcomings,this paper presents a vehicle alarm system based on multi-sensor information fusion.Detailed knowledge of the theory and design of car theft.For example,GSM wireless communication protocol,GPS and base station positioning principle,AT command,infrared sensing principle,the principle of portrait recognition.On the basis of the traditional security technology,the system adds embedded chip,infrared sensor,GPS module,GSM module,camera module and so on.When the car was stolen,the owners can not only receive location information of the car and also receive the thief photos,in addition to send commands to the car stalled,so as to achieve real-time omnidirectional anti-theft function.Experiments show that the automobile anti-theft alarm based on multi-sensor information fusion system research and development,to achieve the complementary multi vehicle anti-theft alarm,application system can be used in car networking system,provides the reference for the application and development of intelligent vehicle anti-theft alarm network.
