Problems solved by technology

[0003] But the automobile anti-theft alarm that prior art manufactures has following shortcoming: 1. The remote controller receives the radio alarm signal distance that anti-theft alarm sends out relatively close, and the signal is greatly influenced by building block, and when exceeding the effective receiving range, the car owner often I don't know, the reliability rate of the remote control alarm is very low
2. When the car is on alert, if the owner leaves the car, especially when the vehicle cannot be seen, there will be no display on the remote control for the owner to inspect the car
3. In case the thief quietly avoids the sensor in the anti-theft alarm installed on the car, cuts the wire, removes the anti-theft alarm, and the remote control has no alarm function
4. When the power supply system of the car itself to the anti-theft alarm fails or the anti-theft alarm fails and the radio alarm fails, the remote control does not display the alarm function.
5. The power supply battery installed on the remote control has a short service life

Abstract

One anti-theft alarm for vehicle with autoamtic radio signal detection and its signal processing method is disclosed. The alarm consists of one bi-directional cipher responding ratio transmitting and receiving unit and one portable remote controller. Detection signal is sent out to make the remote controller possesses continuous radio receiving effect and intermittent powering mode of radio receiving circuit. The present invention solves the contraditional between the service life of battery in the remote controller and the radio signal receiving effect and this results in high reliability of the alarm.

Description

1. Technical field [0001] The invention relates to an anti-theft alarm device, in particular to a signal processing method for an anti-theft remote alarm device for vehicles which adopts radio automatic detection and is suitable for automobiles and motorcycles. 2. Background technology [0002] The automobile anti-theft alarm that prior art manufactures at present, comparatively generally adopts two-way radio remote control mode, comprises, a remote controller, an anti-theft alarm. Its working principle is: remote control: easy to carry with the car owner, can send out radio signals, control the working status of the anti-theft alarm installed on the car, and can also receive the radio alarm signal sent by the anti-theft alarm on the car; anti-theft alarm: use Because it is installed on the car, the anti-theft alarm is responsible for sending out radio alarm signals, and at the same time, it sends out an alarm sound. [0003] But the automobile anti-theft alarm that prior a...
