Problems solved by technology

[0002] With the popularization of vehicles, people have higher and higher requirements for anti-theft vehicles, followed by people's requirements for anti-theft functions of vehicles are also increasing day by day. Now the detection method used by common anti-theft devices is the same as the sensor on the car. Signals are connected, such as detecting signals such as car doors, lights, and ACC. For different models, the installation positions of the door, ACC, lights and other signals are different for each model, which requires the installers to be familiar with the electrical connection diagrams of each model, and requires relatively high skills for the installers. A vehicle often takes a long time
On the other hand, each new car has a maintenance period for a period of time. During the maintenance period, the car owner can obtain free vehicle maintenance from the manufacturer. However, if the car owner changes the electrical wiring of the vehicle without the manufacturer's permission during the maintenance period, it may As a result, the manufacturer refuses to provide free maintenance for the vehicle, so if the owner wants to install an anti-theft alarm on the new car, he may face the danger of losing the free maintenance
To sum up, the main disadvantage of the anti-theft detection method connected with the vehicle sensor signal is that there are many connections, complicated installation, and certain damage to the electrical connection of the original vehicle.

Abstract

The present invention discloses a pressure sensor based on RFID technology and a vehicle anti-theft detection technique. An instantaneous pressure change in the car is detected by the pressure sensor. When the pressure changes, an identity serial number of a driver marked in a mark card can be read by an anti-theft detection device through a RFID reader. The decision of whether driving an alarming device to alarm is made after judging the legality of the serial number of the driver. At the same time, the identity serial number of the driver is read by RFID at a fixed interval (such as 10 seconds); the driver is judged as having left the car if the legal identity serial number of the driver for a continuous fixed times (such as 3 times), and then the defending state is shifted from 'off' to 'on'. Destructive operations, such as cutting an electrical connection line from the original car are not necessary. The present invention has the advantages of simple and convenient in installation; and reliable in anti-theft detection. The present invention is characterized in easy to use and prevail thus is suitable for any car model.
