The car anti-theft system based on GSM mainly includes: vehicle terminal (microcontroller, GPs module, GSM module, sensor circuit), GSM network, monitoring center and user mobile phone. TC35 is a new generation wireless communication GSM module launched by Siemens, which can quickly, safely and reliably realize data, voice transmission, short message service and fax in the system scheme. Ignition locks and manual locks installed on cars cannot effectively prevent cars from being stolen, so many modern cars are equipped with electronic anti-theft alarms. In the event of a theft, the alarm horn will sound for a period of time, thereby turning off the car engine. A communication platform with remote monitoring function is designed, which provides a comprehensive solution for vehicle anti-theft and monitoring, and provides a technical foundation for the development of wireless network of vehicle anti-theft system. It is widely used in many vehicles, but vehicle thefts have not been completely eliminated. There are still many professional thefts that use high-tech means to interfere with and attack the car security system. GSM signal jammer will interfere with the GSM network in the anti-theft system.
