Example Embodiment

[0023] The specific embodiment of the present invention works with a vehicle-mounted terminal and a remote monitoring center.

[0024] Figure 1 is the appearance structure diagram of the ultrasonic vehicle alarm of the present invention. The front panel has a 10-pin connector for connecting power and realizing part of the detection signal input, and a 12-pin connector for other part of the detection signal input and output signal.

[0025] As shown in Figures 2, 3, 4, and 5, the ultrasonic vehicle alarm includes the following components:

[0026] An 8-bit MCU (Single Chip Microcomputer), which is the control center of the entire ultrasonic vehicle alarm.

[0027] A TTL level to RS232 level circuit is used to connect the serial port of the ultrasonic vehicle alarm to the asynchronous communication serial port simulated by the host computer to realize the smooth communication between the upper computer and the lower computer;

[0028] A radio frequency circuit for remote control of ...

Abstract

The invention relates to a ultrasonic vehicle alarm that includes MCU, series port, asynchronous communication circuit, ultrasonic signal emitting and receiving process circuit, libration testing circuit and vehicle signal testing circuit. It adopts the method of combining ultrasonic sensor and GPS to take real time monitoring for vehicle. And it uses GSM/GPRS/CDMA to realize moving monitoring. Thus, monitoring center could realize theft protection function.

Description

technical field [0001] The invention relates to a vehicle safety anti-theft alarm system, in particular to an ultrasonic vehicle alarm. Background technique [0002] In recent years, the domestic private car market has developed rapidly, and vehicle security products have emerged in an endless stream. Vehicle anti-theft devices are the main vehicle security products. At present, most of the domestic anti-theft devices only have simple functions of unlocking the car door and vibration alarm. The disadvantages of these anti-theft devices are that they cannot monitor the conditions in the car in real time; That is, the horn sounds and the side lights flash. If the owner is far away from the car, he cannot obtain the police information in time at the first time, thereby causing losses to the owner. Therefore, in view of the problems exposed in the above-mentioned practice, there is an urgent need for a new type of anti-theft device product that can not only prevent theft of the...
