Design And Inplement For New Vehicle Positioning Device Based On Mobile Network

With the rapid development of industrial technology and the economy, the increasing number of motor vehicles. The car provide convenient for our trip, while also facing be stolen, robbery complex environment, as part of our family property, and how to protect them from abuse, become an urgent problem to be solved.In this paper, the current car alarm technology is analyzed, that in the current network technology under the background of highly developed, car should also be connected to the network, in addition to have itself "security", also should have active safety means such as "traceability". At the same time analyzed the existing have "traceability" anti-theft system, puts forward its popularization and promotion to the main defects: one is the terminal equipment is expensive. Second, the need to pay the service fee to a third party. Three is to use third-party service platform, in network information increasingly severe environment, there is the risk of leakage of personal information and privacy. Based on the analysis in this paper, in order to realize the vehicle can track, reduce the cost, avoid to use the third party for the purpose of public service, that demand for ordinary families use, designed to achieve the car positioning system based on mobile network. The system consists of GPS vehicle positioning information collected, generated through the GSM data transmission and processing of the vehicle positioning or track diagram stored in the server database, the user can be accessed through any internet-enabled devices to provide information of web pages, can obtain the current position of the vehicle or the movement track of a period of time.This paper analyzes existing car positioning system, needs improvement measures are put forward in view of the family use and implementation. To optimize the design of the monitoring terminal and service platform will use costs by 57%; Improve the methods of user queries, as a WEB page to map way, avoid limited terminal and software, improve the compatibility of user equipment; Using self-built monitoring and service platform, to avoid a large number of users’ information gathering, autonomy and control equipment was improved, and reduce the risk of personal privacy information leakage; Monitor the client and server can be convenient to install encryption module, protection of information security in the transmission. The subject in the process of design and implementation of key issues put forward solutions and implement. Speed is used to dynamically adjust the positioning time intervals, to ensure the effectiveness of the positioning, avoid locating blind area; The DDNS technology solve the problem of dynamic IP address of a service, guarantee the monitoring terminal can connect server upload data at any time; Defines the monitoring terminal and server data transfer protocol format, can guarantee the stability of data transmission. Through the last of the system function and performance test show that the system function is normal, stable running, easy to use, the effect is good.
