Car theft-prevention system based on GSM network

Abstract

The invention relates to an automobile anti-theft system based on GSM network, comprising a central controller (MCU), a car condition testing module, an anti-theft protecting and control module, a local alarm module, a state display module, a voice monitoring and output module, a wireless communication module (GPRS), the wireless communication module is communicated with the central controller through a serial port, the system accesses the GSM / GPRS network by the wireless communication module, realizes report, monitoring and anti-theft control of car states through the short message function. Comparing with the prior art, the automobile anti-theft system of the invention utilizes the GSM short message service to realize data bidirectional transmission, has priority, high completing rate, low error rate, adopts the short message mode to monitor cars, has low communication cost, high spectrum utilization rate, large system capability, good security, strong antijamming capability, good communication quality, automatic roam.

Description

technical field [0001] The invention relates to an automobile anti-theft system, in particular to an automobile anti-theft system based on a GSM network. Background technique [0002] With the rapid development of my country's economy and science and technology, people's living standards are improving day by day, and more and more people have cars. The popularity of automobiles has brought great convenience to people's lives, but the ensuing car theft problem is seriously perplexing the majority of car owners. Although people take various anti-theft measures, the increasingly rampant means of theft still makes car owners hard to guard against, and the anti-theft situation is becoming more and more severe. [0003] At present, commonly used car anti-theft devices are mainly divided into mechanical anti-theft devices, electronic anti-theft devices and network anti-theft devices. The mechanical anti-theft device is the simplest and cheapest anti-theft device on the market. It...

AI Technical Summary

Problems solved by technology

The mechanical anti-theft device is the simplest and cheapest anti-theft device on the market. Its principle is simple. It mainly locks the steering wheel, control pedal or handle. This kind of anti-theft device has the advantages of cheap price and easy installation, but the anti-theft effect Poor and inconvenient to use; the electronic anti-theft device uses an electronic identification code for the car lock, and a password is required for unlocking or matching keys to prevent theft. The biggest feature of the electronic anti-theft is password unlocking and sound alarm. Remote control car search, central door lock remote control function; network anti-theft device is a new anti-theft means, using modern technology to achieve real-time information feedback, with many functions, which rely on the global satellite positioning system (GPS) as the representative, but there are satellite positioning Disadvantages such as ground monitoring center, unstable signal, and high price

[0004] In addition, there are still many problems in the use of the existing anti-theft devices, such as the short working distance, the noise generated by the alarm polluting the environment, false alarms, etc., which bring great troubles to people's lives.
