Description

Technical Field

[0001] The utility model mainly relates to the technical field of vehicle anti-theft, and in particular to an engine anti-theft alarm system. Background Art

[0002] As the number of cars in the country has grown significantly, the problem of car theft has also gradually increased;

[0003] Engine anti-theft mainly controls whether the engine module works or not by combining the chip code on the anti-theft key with the anti-theft module code; this method has a single anti-theft alarm method. When the thief steals the key, he can drive away the vehicle. At the same time, this method is not easy to notify the owner in time. When the owner finds that the vehicle is lost, the thief may have destroyed the GPS signal sending and receiving part to make its positioning function lose, making the vehicle unable to be found. Utility Model Content

[0004] The utility model mainly provides an engine anti-theft alarm system to solve the technical problems raised in the above background technology.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] An engine anti-theft alarm system includes a vehicle body controller, an ignition key, an ignition switch, a vehicle engine, and a mobile terminal;

[0007] The ignition key is electrically connected to the ignition switch, the ignition switch is electrically connected to the vehicle body controller, and the vehicle body controller is electrically connected to the vehicle engine;

[0008] The body controller comprises:

[0009] Ignition lock, used to lock and open the ignition switch;

[0010] A signal transceiver unit, used for signal interaction connection with a mobile terminal;

[0011] A monitoring unit, used to photograph the person in the driver's seat;

[0012] A recognition unit, used for performing face recognition on a person in the driver's seat in an image captured by the monitoring unit;

[0013] Face database, used to record the face data of common drivers;

[0014] Alarm unit, used for sounding an alarm and sending alarm information.

[0015] Furthermore, the vehicle body controller further includes:

[0016] The positioning unit is a GPS locator used to locate the vehicle position;

[0017] Door locking unit for remotely locking the vehicle's doors.

[0018] Furthermore, the engine anti-theft alarm system also includes:

[0019] The seat sensor is a pressure sensor installed inside the driver's seat, and the seat sensor is electrically connected to the body controller.

[0020] Furthermore, the monitoring unit is an ultra-clear camera installed on the A-pillar on the driver's side of the vehicle.

[0021] Furthermore, the alarm unit is an audible and visual alarm installed in the vehicle.

[0022] Furthermore, the ignition key includes a key chip.

[0023] Compared with the prior art, the beneficial effects of the utility model are:

[0024] Before the driver starts the car engine through the ignition switch, the body controller of this system will compare and match the driver's facial information through the monitoring unit, recognition unit, and face database. If there is a mismatch, a signal will be sent to the mobile terminal. The driver must obtain the owner's authentication permission before starting the vehicle. On the one hand, it notifies the owner of abnormal conditions in time, and on the other hand, it enhances the engine anti-theft effect;

[0025] At the same time, this type of identification, authentication and licensing method can better deal with the situation where the car owner lends the vehicle to a friend. At the same time, through the seat sensor, it can start identifying the driver as soon as he sits in the driver's seat, ensuring that the vehicle transmits whether it is stolen information at the first time, which is very practical.
