Ultrasonics induction type vehicle anti-stealing device

Abstract

The invention relates to an ultrasonic wave induction-type automobile anti-theft device, which comprises an automobile anti-theft host machine, at least one ultrasonic detector electrically connected with the automobile anti-theft host machine and at least one warning device electrically connected with the host machine. When a driver and passengers leave the automobile and start the device, then all the ultrasonic detectors respectively perform scanning to the reflected values of the ultrasonic waves in the positions corresponding to the ultrasonic detectors and preserve the reflected values in the host machine, if a person enters into the automobile or the glass of the automobile is broken, the change of the reflected values of the ultrasonic waves in the corresponding positions is caused respectively, the host machine responds to drive the warning device to send out warning after receiving the abnormal signal, and the warning device is provided with a high-decibel alarming horn and a GSM or CDMA mobile communication device which can be connected to the telephone of a vehicle owner. The invention also comprises a wireless remote controller used for controlling the starting and closing of the anti-theft function of the anti-theft device. By adopting the ultrasonic wave induction-type automobile anti-theft device with the structure, the false alarm phenomenon cannot occur, and the remote alarm can be realized.

Description

technical field [0001] The invention relates to an ultrasonic induction type automobile anti-theft device, in particular to an ultrasonic induction type automobile anti-theft device which uses an ultrasonic detector to detect the state in the vehicle. Background technique [0002] Many surveys have shown that in today's car environment, car owners are most worried about car theft. Most of the traditional car anti-theft devices on the market now use vibration detectors to detect whether the vehicle is vibrated or whether the door is opened to give an alarm. Because the vibration detectors are easily disturbed by the environment and cause false alarms, it is easy to cause car owners to paralyze their thinking. In the event of a theft, it cannot play a proper anti-theft role. On the other hand, most of the traditional car anti-theft devices only use the alarm horn as the alarm signal, and the sound of the alarm is close, and the range of sound transmission is small, and the car...

Most of the traditional car anti-theft devices on the market now use vibration detectors to detect whether the vehicle is vibrated or whether the door is opened to give an alarm. Because the vibration detectors are easily disturbed by the environment and cause false alarms, it is easy to cause car owners to paralyze their thinking. In the event of a theft, it cannot play a proper anti-theft role. On the other hand, most of the traditional car anti-theft devices only use the alarm horn as the alarm signal, and the sound of the alarm is close, and the range of sound transmission is small, and the car owner is far away. It is impossible to effectively notify the car owner, and it will also cause noise interference to the surroundings in case of false alarms, so it is not ideal
