Automobile Security Communications System Design And Realization Based On Gsm

Along with the economy development of national, the personal car's number growing quickly, vehicle theft case has increased year by year, originally adopted widely old mechanical lock type alarms already cannot satisfy the needs of modern society, with the development of science and technology, especially the electronic technology and network communication technology development, the automobile guard against theft system also design is more and more advanced, more scientific and more humanized anti-theft system is to solve the current society auto security problem. This design is an important means to solve traditional automobile guard against theft system model of the shortcomings and the insufficiency, and application of new electronic communications technology and design a new type of car anti-theft alarm system.This system can solve the traditional physical model of passive burglar alarms way, integrates the advanced GSM communication module, using SMS (short message service) to the owner by the use of text messages between users achieved with the two-way communication. Interactive, active alarm model, this module structure, high efficiency high integration is concise, reliability and safety is very stable.This system based on GSM (global system for mobile communications) wireless communication network and design are discussed. The principle of car anti-theft alarm system under the composition and function of the realization of the system, studies the GSM communication system in auto security technology application status, the author puts forward a monolithic integrated circuit AT89S52, ultrasonic sensors, TC35i communication module of guard against theft system solutions. This paper focuses on the TC35i communication module based on single-chip microcomputer control principle and circuit implementation, completion of the system of the overall design, hardware circuit design and the system communication module software debugging and the application of this system shortfall in the developing direction and made analysis and prospects.
