Abstract

The utility model belongs to an anti-theft device for motor vehicles. The utility model is characterized in that the utility model also comprises a wireless receiving plate (5) and a wireless parking remote controller (6), wherein, the receiving plate (5) is connected with the input end of a centering controller (1). An anti-theft sensor (3) and a password input unit (2) are separately connected with the input end of the centering controller (1), and an execution unit (4) is connected with the output end of the centering controller (1). The utility model has the advantage of convenient operation, with the remote control function, comprising remote control locking, remote control releasing and remote control looking for the motor vehicles, so the anti-theft device for motor vehicles is convenient for the traffic police and other relevant law enforcement officials to be used, and simultaneously is suitable for being used by the motor vehicle owners.

Description

A kind of alarming device for automobile anti-theft

The utility model belongs to a kind of anti-theft device for motor vehicles.

Existing alarming device for automobile anti-theft, main by a central control unit that is installed in operator's compartment or the engine room, parts such as password input or remote control PIN PAD are formed.Generally have the state of alert, disarm state, warning lock-out state.Under the state of alert,, pass to central control unit, warning piece, warning that controller control is made up of dynamic loud-speaker etc. by the stolen signal of theft-proof sensor perception vehicle, the point of cutoff ignition system can't be lighted a fire vehicle simultaneously, and driving engine can't be worked, enter the warning lock-out state, reach antitheft purpose.Behind PIN PAD or remote controller input password, enter disarm state from the warning lock-out state.By normally killing engine or the PIN PAD input instruction, enter functions such as the state of alert from disarm state.Described existing structure is once when not entering the state of alert, when perhaps burglary-resisting installation is decreased, just can't play antitheft effect.

The purpose of this utility model is to remove central control unit, PIN PAD, theft-proof sensor outside the warning execution unit, increases a radio reception plate and radio parking remote controller, can reach the anti-theft alarm effect like this, and have distant control function, and simple to operate.

The utility model is to realize like this, it includes central control unit, PIN PAD, theft-proof sensor and execution unit, it is characterized in that: also include radio reception plate and radio parking remote controller, wherein wireless receiving plate 5 is connected with central control unit 1 input end.Described theft-proof sensor (4) and PIN PAD (2) are connected with the input end of described central control unit (1) respectively, and described execution unit (4) is connected with the mouth of central control unit (1).Basic functional principle is: stop from the remote controller emission, inactive radio command, after the wireless receiving plate is received, be processed into digital command and send into central control unit, stop by the prompting of central control unit control warning execution unit, the combustion cutoff ignition system, make vehicle force to stop, or vehicle also can't ignition trigger when being not activated, cooperate the driver have beeper warning execution unit can also be used to vehicle because of the situation that does not enter the state of alert and lose under, the car instruction is looked in emission, after the radio reception plate receives, by original beeper transmission circuit, the emission answer signal, according to answering radio signal, can be used for looking for car by radio direction finding.

Further specify below in conjunction with embodiment:

Fig. 1 is a block diagram of the present utility model

Fig. 2 is embodiment wireless receiving plate 5 circuit diagrams

Fig. 3 is embodiment remote controller 6 circuit diagrams that stop

Fig. 4 is the utility model diagram of circuit.

With reference to Fig. 1, described central control unit 1 mainly is made up of single-chip microprocessor.PIN PAD is a keypad, and is connected theft-proof sensor 3 by data line between the central control unit, and it is made up of car door theft-proof sensor, vibration sensor, be connected to central control unit 1 by private siding, carry out function corresponding, described execution unit includes loudspeaker, the centralized control lock, beeper alarm transmission circuit, the beeper annunciator, they are connected on the central control unit (1) by dedicated signal lines, carry out function corresponding, these are prior art.

The radio reception plate 5 that the utility model adopts comprises that heterodyne reception circuit or ultra-audio circuit constitute, see Fig. 3, receive frequency, select for use about VHF band 150mHZ, also can select other frequency for use, the radio signal that receives, being drawn by the chip change is the digital signal instruction, send into central control unit 1 by data line, carry out function corresponding by central control unit 1.The digital signalling form can be selected for use the prior art simulated dual voice-frequency signaling or the world to lead for No. 1 and exhale a yard POSCAG sign indicating number.Present embodiment adopts double-tone analogue signalling transmission frequently, is kept pouring in by double-tone and changes that chip is defeated to change the CPU that numerical code is sent into centralized control 1 into.

Wireless parking remote controller 6 as use double-tone be analogue signalling frequently, the interphone that has the dual-tone dialing function of available C-150 interphone or general traffic constable adapted.By interphone emission or have the radio transmitter execution unit 4 of same function, flow process such as Fig. 4 of the very high frequency (VHF) command signal that double-tone is modulated frequently.

The utility model has the advantages that, easy and simple to handle, have the control of shaking function, comprise Shake the control locking, shake control and remove, shake to control and look for car etc., be convenient to relevant the holding such as traffic-police The method librarian use also is applicable to car owner's use simultaneously.
