[Abstract]:Embedded technology, computer vision technology, human-computer interaction technology and GPS positioning technology GPRS communication technology has been increasingly widely used in the automotive field. The application system, technical method analysis, research, design and experiment, the research and design of the vehicle image monitoring system are helpful to driver's safe driving and accident responsibility determination. It is helpful to reduce the economic loss of vehicle owners, to promote the application of automobile safety technology, to ensure the safety of consumers' lives and property, and to maintain social stability. Based on the embedded ARM processor, a vehicle image monitoring system is designed. The system has two main functions: video image monitoring recording and GPS mobile alarm, and it has two auxiliary functions. Map navigation and video music entertainment. The vehicle image monitoring system has the characteristics of functional practicability and convenient operation, as well as the characteristics of active safety technology and passive safety technology. In this paper, a method of parking relative mobile vehicle theft protection based on GPS positioning is proposed. The method acquires vehicle position information by GPS location technology. When the moving distance of the vehicle is larger than the pre-set distance data of the system, the vehicle position information is sent to the three mobile phone numbers pre-set by the system through the GPRS network. According to the SEGOS-RE process, a relatively complete system requirement model is established, and the environmental factors involved in the system are explained by using the environmental analysis method of the automobile image monitoring system. The object identification and decomposition of the vehicle image monitoring system are used to explain the relationship between the system targets, and the function structure of the system is established by the use case of the vehicle image monitoring system. In this paper, the interface circuit of AT070TN83 V.1 LCD screen and HST-TPA7.1G touch screen interface circuit are designed. The USB extended interface circuit based on AT43301 and the GTM900C GPRS module interface circuit of NS-1315 GPS module are designed. The program driver of the corresponding equipment is explained. The system function is realized by programming, and the function test and module test of the system are carried out. The test results show that the running interface of the system is simple, the operation is convenient, the program branch is correct, and the video image display picture is clear. The communication between GPRS and fluency GPS can meet the requirements of application. The test results verify the validity of the program design and implementation.
