Description

Motor vehicle antitheft, the anti-misfortune apart from remote control equipment (RCE)

A kind of motor vehicle antitheft, the anti-misfortune apart from remote control equipment (RCE) belong to the motor vehicle antitheft field.

Because self-propelled vehicle is often stolen, be robbed, therefore antitheft, anti-misfortune has become the outstanding problem of self-propelled vehicle.Present motor vehicle antitheft mainly adopts burglar alarm, promptly uses the cipher control high-tension coil.Commonly used is to have button switch on the burglar alarm, and the password of chaufeur input oneself is opened password earlier during driving, and driving engine could normal operation.The robber steals Che Shiyin and does not know password and cause the burglar alarm warning, reaches the purpose of anti-theft alarm.Advanced is to have to transmit and receive the distant control anti-theft alarming device that two parts constitute.As: the remote controller that existing burglar alarm has the driver to carry, remote controller has four buttons to constitute, i.e. unlatching, closed door button, preheating started car button, anti-misfortune button, sought the car button, self-propelled vehicle is normally exercised the Times alarm system and is not worked, and when the driver is stopped from car, presses the closed door button, connect the annunciator power supply, annunciator is started working, and sends alerting signal as people's motor-car, attempt driving self-propelled vehicle, reaches antitheft, anti-purpose of robbing." Chinese patent " on April 3rd, 1991, disclosed application number was for another example: 90217097, and the applying date: 90.08.01, the applicant: leaf is respectful, utility model title: automobile motorcycle anti-theft equipment.This automobile motorcycle anti-theft equipment is made up of remote controller two parts that vehicle-mounted Car Burglar Alarm and driver carry.When the driver when car is handled affairs, as long as close the power supply of remote controller switch, Car Burglar Alarm just enter automatically monitor on the alert.As long as someone attempts to steal car and action to some extent, Car Burglar Alarm promptly sends warning tone and cuts off fuel feeding, power supply, and vehicle can't be started, and the while remote controller sends the alarm call optical signal and reminds the driver to return the vehicle guard station at once.Above-mentioned several burglar alarm all can play the warning effect in various degree, but has following several respects problem

1, all must manual operation remote controller or input password, warning is started working, and make a fault easily or fail to report phenomenon because of remote controller does not have demonstration.

2, set off firecrackers, ectocine such as wind and rain is prone to flase alarm, give people life cause confusion, national departments concerned has been made restriction.

3, the anti-function of robbing can not normally be brought into play, and remote controller need be thought operation, when the people is hit by the external world, can't operate when lying in a comatose condition.

4, remote control distance can only be in 20-40m, above losing function apart from remote control, the remote operated purpose of out of reach.

5, being prone to steathily, sign indicating number duplicates robber's car.

The purpose of this utility model just is to overcome the deficiencies in the prior art, provide a kind of simple in structure, reliable operation is sensitive, can not occur reporting by mistake, fail to report, work does not need manual operation at every turn, the motor vehicle antitheft of round-the-clock advantage such as in running order, the anti-misfortune apart from remote control equipment (RCE).

The purpose of this utility model realizes in the following way:
