Description

The anti-method of robbing of motor vehicle antitheft and apart from remote control equipment (RCE)

A kind of motor vehicle antitheft is prevented the method for misfortune and apart from remote control equipment (RCE), is belonged 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, the anti-misfortune, the main method that adopts manual operation burglar alarm or remote control transmitter, be not work under annunciator or the projector normal circumstances, as driver during from car, after manual operation knob or setting code and the energized, burglar alarm or remote control transmitter are started working.Burglar alarm is promptly used 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, driving engine ability normal operation, and 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 steals the car self-propelled vehicle as people's motor-car, attempt and sends alerting signal, 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 impact, national departments concerned has been made restriction.

3, the anti-function of robbing can not normally be brought into play, and remote controller needs manual 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.

Purpose of the present invention just is to overcome the deficiencies in the prior art, provides a kind of each work not need manual operation, round-the-clock in running order remote operated method.Advantages such as another object of the present invention provides a kind of for realizing above-mentioned remote control thereof design-calculated motor vehicle antitheft, the anti-misfortune apart from remote control equipment (RCE), and that this device has is simple in structure, reliable operation is sensitive, can not occur reporting by mistake, fail to report.

The objective of the invention is to realize in the following way:

This motor vehicle antitheft, anti-method of robbing, it is characterized in that: utilize the remote operated method of distance, promptly carry projector by navigating mate, with the cooresponding receptor of password, projector, receptor are round-the-clock in running order, do not need to work all that the very important person is operation at every turn, when navigating mate leaves the self-propelled vehicle setpoint distance, after receptor did not receive signal, receptor actuating unit action automatic cutting off table motor-car way circuit was realized apart from remote control.

Another object of the present invention realizes in the following way:

For realizing said method design-calculated motor vehicle antitheft, the anti-misfortune apart from remote control equipment (RCE), it is characterized in that: comprise projector that navigating mate carries, and housing in receptor and the automobile way circuit shelter in self-propelled vehicle that is installed in series, projector comprises strength circuit 1, encode circuit 2, coded modulation circuit 3, receptor comprises: acceptor circuit 4, amplification and rectification circuit 5, decoding circuit 6, monostable circuit 7, executive circuit 8, after receptor did not receive signal, receptor actuating unit action automatic cutting off table motor-car way circuit was realized apart from remote control.
