Automobile anti-theft and starting system based on CAN (controller area network) bus application

Abstract

The invention provides a system for realizing automobile anti-theft and one-button starting based on CAN (controller area network) bus application. An automobile anti-theft and starting device based on CAN bus application consists of a CAN bus driver, a single chip microcomputer, an inclination angle sensor, a data conversion output element, a warner, an engine starting control element and a power supply formed into an integral structure, the CAN bus driver receives signals and transmits the signals to the single chip microcomputer for carrying out automobile starting, automobile locking and automobile unlocking, in an automobile locking state, corresponding data of automobile locking occurring on the CAN bus passes through the CAN bus driver, when the automobile vibrates, a sensor sends out output signals, the single chip microcomputer processes the signals and determines the signals, the data conversion output element outputs the signals, and the warner is driven to generate warning sound. The system has the advantages that aiming at the problems of the traditional automobile anti-theft function, the functions of one-button starting, anti-theft setting, anti-theft reliving, anti-theft warning and the like are realized, the compatibility with different automobile types is realized, in addition, the safety is high, the reliability is high, and the use is simple, convenient and comfortable.

Description

technical field [0001] The invention provides a car anti-theft and start-up system based on CAN bus application, especially a method for controlling various car anti-theft and one-key unlocking and starting cars with CAN bus application. Background technique [0002] With the improvement of the quality of life, the use of cars has become an important transportation work for every family, and it belongs to personal assets, while car theft has caused great property losses to the people. Automobile anti-theft becomes the important issue of protecting people's property for this situation. At present, the anti-theft device installed on the common car needs to ensure the anti-theft of each door, car engine, car corner and other parts. The traditional electronic anti-theft device needs to be specially equipped with a check element for each anti-theft point. And connect a line to the anti-theft device host for each detection cost. For ordinary cars, 12 or more wirings are usually r...

Problems solved by technology

At present, the anti-theft device installed on the common car needs to ensure the anti-theft of each door, car engine, car corner and other parts. The traditional electronic anti-theft device needs to be specially equipped with a check element for each anti-theft point. And connect a line to the anti-theft device host for each detection cost. For ordinary cars, 12 or more wirings are usually required. In this way, it is not only time-consuming and laborious to install the car anti-theft device, but also the existence of too many lines is easy to be damaged. Failure, complicated maintenance and other problems, it is not perfect enough in use, not simple enough, not convenient enough
