Design And Application Of Remote Anti-theft Vehicle Terminal On Mobile Communication Network

The global economy continues to grow and develop,and the level of science and technology is changing with each passing day.Various means of transportation have emerged.And the car is the most familiar one,it shorten the distance of space,save time for travel,and brings great convenience to everyone's life and work.At present,the rapid development of the express industry is also the result of the continuous popularization of cars.Every day,a large number of cars were carrying many goods across the country.Cars are indispensable to life and work,while the issue of car safety and anti-theft need to be paid more attention.One of the reasons for a large number of cars happened traffic accidents is that the accidents are not notified and dealt with on time,which is a big threat to the safety of life and property.The increasing number of vehicle thefts has drawn everyone's attention.For automobile management,traffic safety,and anti-theft,this paper studies a remote anti-theft vehicle terminal based on mobile communication network.The main control unit uses a single-chip microcomputer STM32F103RET6 to load the uCOS-? system and integrates the technology of mobile communication network,the technology of GPS positioning,the technology of RFID,the technology of image acquisition,the technology of OBD and acceleration sensor technology connecting the TCP network background and the owner's mobile phone.Form a close triangle relationship between the terminal,the network background and people,which make batch car management possible.The terminal device is connected to the car's braking and door locking system,which can effectively prevent the owner from fatigue driving.Traffic accidents using this system can be fed back to the background and backup as soon as possible.The mobile phone number can achieve the effect of real-time alarm to maximize the personal safety of the owner;On the basis of timely anti-theft alarm,the vehicle terminal tracks the stolen vehicle in real time and monitors the scene in the car to facilitate the recovery of the vehicle.For each module of the car anti-theft terminal,this article describes the technical knowledge of the main functions in detail.The function and hardware requirements are formulated according to market requirements to determine the design of the vehicle terminal.The hardware selection is based on the module performance,price size,the driver and interface to consider,and then the circuit design schematic diagrams of the key modules are given.In software design,the system tasks are established according to the communication protocol of each module and specific software functions,which is based on the uCOS-? real-time operating system.The tasks are independent and in contact with each other.And the functional requirements of the design is completed under the coordination of the uCOS-? system core.
