Research And Design Of Vehicle Intelligent Anti-theft System

With the vigorous development of China's auto industry, China's car ownership is also gradually increased, this also causes some problems and one of them is the increasing of car theft incidents in China. The anti-theft system of the domestic automobile is also mixed up with good and bad performance. What's more, there even exist great differences in the performances and the qualities of these anti-theft system, and most of the car anti-theft system can not play a good role in the function of anti-theft. Therefore, a reliable and intelligent vehicle anti-theft system is urgently needed.In this paper, the design of this car anti-theft system contains two parts, one part is the hardware design of the system, and the other part is the design of the software design of the system. Main function contains the monitoring for the surrounding environment of the car, which is including the monitoring of the auto vibration, and the collection of the images around the car; The users can check and control the car alarm system by the way of WEB. In addition, the car alarm system also has the function of early-warning through the analysis of the location information of the abnormal situation of the car and judging whether the vehicle in the current position is safe or not, and notifying the owners by sending e-mail automatically.First, The hardware design of car anti-theft system is described, the main controller and some peripheral circuits used in the design of the car alarm system are described in detail, the main control using the MCU STM32F103ZTE6, the peripheral circuit contains the camera module, the password keyboard module, GPRS module, GPS module, vibration sensor module and car circuit control module and other modules. Through these hardware circuit as the carrier, the server can collect and process the location information and the environment information of the vehicle.Then the software part of the system is described, the system software is divided into two parts of the design. One part is the software that runs on the hardware, and the other part is the server software. The main two aspects of the software design requirements, design difficulties are analyzed, a scheme suitable for this system is designed, and the software is written according to the program.The deployment of server software from the planning of basic software, including the selection and installation of the operating system, the deployment of the database, the deployment of NGINX server, the network topology planning and so on. Considering the concurrency problem of server software, server software architecture adopted cluster software architecture, each service the three servers deployed, in front of three sets of the same server through a nginx server business request forwarding, let the three servers can undertake system balanced task.Testing is mainly two aspects, one is the auto alarm system hardware of testing; the other one is server software test. The basic idea of the two tests is the unit tests, and then the integration test, the test system. Finally, repeated after the iterative system to ensure more successfully running on the line. Car owners can use the system design of the automobile burglar alarm system, a good management of their own cars and to reduce the risk of car theft.
