Abstract

The utility model discloses a radio paging anti-theft device for a motor vehicle. The utility model comprises a pager, a controller, a driver and an alarm. The utility model is characterized in that the output terminal of the pager is connected with two voltage comparators, and the output terminals of the two voltage comparators are respectively connected with the input terminal of a single chip computer; the output terminal of the single chip computer is respectively connected with the driver and the alarm, and the driver is connected with an automobile electronic ignition device and a starting motor device. The utility model can realize remote anti-theft control for the motor vehicle; when the motor vehicle is illegally stolen, the motor vehicle is automatically stopped and alarms through radio paging. The utility model has the characteristics of convenient control, simple and direct control, and long control distance. The utility model has the advantages that the system identification ability is strong, and the utility model is not easy to be out of order.

Description

Motor vehicle radio paging anti-joyride device

Technical field

The utility model relates to a kind of anti-theft device for motor vehicle, particularly a kind of motor vehicle radio paging anti-joyride device.

Background technology

In China, annual self-propelled vehicle dramatic growth, automobile also extensively enters ordinary people family, does not also occur but the thing followed is a situation of stealing power actuated vehicle, and is growing trend, brings serious harm for people's life.For a long time, people are seeking the theft-proof way of a kind of solution power actuated vehicle always.The current mobility vehicle, generally all adopt far infrared distance type burglar alarm, utilize remote controller to send telecommand and cut off the electronic or warning of starting, thereby reach antitheft purpose, but it can only closely be controlled, can't realize distance control, the vehicle of illegally being stolen is stopped automatically and report to the police.Disclose a kind of radio call monitor-type car alarm though the patent No. is 00227139.7 patent, it can realize remote monitor, and it has the system identification ability, easy out of order shortcoming.

Summary of the invention

Problem to be solved in the utility model is, a kind of motor vehicle radio paging anti-joyride device is provided, and it can realize the remote antitheft control of power actuated vehicle, at power actuated vehicle during by trespassory taking, by radio call, power actuated vehicle is stopped automatically and reports to the police.

The technical solution of the utility model is achieved in that it is made up of pager, controller, actuator and annunciator, it is characterized in that: the mouth of pager is connected with two voltage comparators, the mouth of two voltage comparators links to each other with the input end of micro controller system respectively, the mouth of micro controller system is connected to actuator and annunciator respectively, and actuator links to each other with the starter motor device with the electronic ignition device of automobile; Actuator is made up of two group relaies, and a group relay is by relay J ₁And J ₂Compose in parallel J ₁Normally closed contact and J ₂Coil series connection, J ₂Normally closed contact be connected with the electronic ignition circuit of self-propelled vehicle, another group relay is by relay J ₃And J ₄Be composed in series J ₄Normally closed contact and J ₃Centre tap connect J ₃Normally closed contact be connected with the electromagnet of cutout relay, cutout relay is connected with self-propelled vehicle motor circuit; Annunciator is made up of language module and loud speaker; Between actuator and the micro controller system hand push button is housed.

The utility model has manually and the paging password setting device simultaneously, therefore has the characteristics that control is conveniently simple and direct, command range is far away, and the utility model adopts micro controller system to control, and it is strong to have the system identification ability, is not easy out of order advantage.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

As shown in Figure 1 and Figure 2, the utility model is made up of pager, controller, actuator and annunciator, the mouth of pager is connected with two voltage comparator LM324, the mouth of two voltage comparator LM324 links to each other with the input end of single chip computer AT 89C51 respectively, the mouth of single chip computer AT 89C51 is connected to actuator and annunciator respectively, and actuator links to each other with the starter motor device with the electronic ignition device of automobile; As shown in Figure 4, actuator is made up of two group relaies, and a group relay is by relay J ₁And J ₂Compose in parallel J ₁Normally closed contact and J ₂Coil series connection, J ₂Normally closed contact be connected with the electronic ignition circuit of self-propelled vehicle, another group relay is by relay J ₃And J ₄Be composed in series J ₄Normally closed contact and J ₃Centre tap connect J ₃Normally closed contact be connected with the electromagnet of cutout relay, cutout relay is connected with self-propelled vehicle motor circuit; Annunciator is made up of language module HL-169B and loud speaker; Between actuator and the single chip computer AT 89C51 hand push button is housed.During use, at first by hand push button password is set, for example setting code 21 is for forbidding vehicle launch, and 32 is vehicle launch, and the car owner only need pass through the cipher control vehicle launch like this.When the car owner leaves vehicle, can be by importing password or information Control vehicle launch to pager or stopping.
