Abstract
The utility model relates to a remote-controlled theft proof and antirobbing alarm device for cars, which belongs to a remote-controlled alarm device which adopts the electronic technology, used for antirobbing alarm of the cars. The utility model is characterized in that the remote-controlled theft proof and antirobbing alarm device is provided with a receiving module which can receive the radio paging information, a shaping circuit, a pulse circuit, a switch circuit which are connected step by step, and is also provided with an encoder and a decoder which are in one-to-one correspondence with each vehicle. When the stolen and robbed vehicle generates, a telephone can be used for paging the remote-controlled alarm device, so that the vehicles can automatically extinguish and alarm. The guard state of the vehicles can be unlocked by the special encoder and the decoder. The utility model solves the problems that the vehicles can not be extinguished by remote control, and the alarm state is easy to relieve. The utility model can effectively prevent the vehicles from stealing and the human body casualty.
Description
The utility model belongs to the remote annunciator that adopts Eltec.
At present, alarming device for automobile anti-theft be mostly with the illegal unlatching by car door as the triggering source, the local circuit of Control of Automobile or oil circuit make the driving engine cisco unity malfunction again, reach antitheft purpose.There is following shortcoming in above-mentioned prior art: 1. can not carry out Long-distance Control, in case stolen robbing taken place, the offender still can drive away car; 2. warning is easy to remove alarm condition after starting; 3. lack ACTIVE CONTROL, have only that trespass could start-up system work after taking place.
The purpose of this utility model is exactly to overcome the shortcoming that above-mentioned prior art exists; providing a kind of can stop working and warning simultaneously at the long-distance remote control vehicle; and except that isolated plant, report to the police in case start the anti-rifle annunciator of Long-distance Control automobile burglar that its guard mode can not arbitrarily be removed.
The purpose of this utility model can realize in the following manner:
Annunciator is provided with master control partial sum coder, demoder, the master control part is connected to form step by step by the receiver module I that can receive radio call information, shaping circuit II, pulse circuit III, switch circuit IV, the power circuit V connects above-mentioned each circuit respectively, the switch circuit IV also connects demoder JM, coder BM is portable, is located at outside the complete machine and is carried by the car owner.Each annunciator has coder separately, and the demoder in coder and the machine is corresponding one by one.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a master control partial circuit block diagram
Fig. 2 is a master control partial circuit schematic diagram
Fig. 3 is relay contact circuit figure, and BK represents controlled circuit among the figure
Fig. 4, Fig. 5 are respectively coder, decoder circuit schematic diagram
In the present embodiment, the receiver module I that can receive radio call information adopts the MC2833 chip; The shaping circuit II is made of be linked in sequence NAND gate IC1A, ICIB (being 4011 chips) of aerotron N1; Burst pulse oscillator, inverter ic 1D (4011 chip) that the pulse circuit III is made up of sequential pulse generator IC2 (4017 chip), integrated timer IC3 (NE555 chip) and peripheral cell connect and compose step by step, and inverter ic 1D also meets the reset terminal RST of sequential pulse generator IC2 through diode D7; The switch circuit IV is provided with silicon control T1 and field effect transistor J1, the series arm of photoelectrical coupler O1, diode D2, resistance R 10, the series arm of self-contained battery B1, and the series arm of aerotron N2 and relay J, the control utmost point of silicon control T1 connects the Q2 end of sequential pulse generator IC2 through current-limiting resistance R7, the input end a of field effect transistor J1 connects the pin 23 of demoder JM, the positive pole of battery B1 in the light-emitting diodes pipe end b of photoelectrical coupler O1 meets sb. at the airport, the mouth e of photoelectrical coupler O1 connects the base stage of aerotron N2, and end e also meets the end EMA of sequential pulse generator IC2 simultaneously through resistance R 9; Contact JK1~the JKn of relay J inserts other controlled circuits BK such as the power circuit, alarm speaker, electric control door lock, gate light of automobile inner high voltage bag respectively, and the W in the power circuit V is a three terminal regulator.
Coder BM, demoder JM adopt UM3758~108AM chip.Each annunciator all is furnished with the coder of oneself, corresponding one by one with the demoder in the machine, when annunciator is in locking state, the available dedicated line couples together them by P1 socket (Fig. 2, Fig. 3), if their sign indicating number is corresponding correct, then the 23rd pin output low level of demoder JM is ended field effect transistor J1, so removed the conducting state of silicon control T1, thereby removed the lock-out state of annunciator.Coding, decoding chip can have hundreds of thousands of kind coded combination.
(following referring to Fig. 1) receiver module I receives radio-paging information that paging station sends to its analysis of decoding, if decoding is correct, then pulse of mouth 2 outputs, after aerotron N1 shaping is anti-phase, deliver to the further shaping of NAND gate IC1A, IC1B, be input to the CLK of input end all the time of sequential pulse generator IC2 again.When the receiver module I receives correct paging information for the first time, then the mouth Q1 of sequential pulse generator IC2 exports high level, the burst pulse oscillator work that this high level is formed integrated timer IC3 and peripheral cell, if receive for the second time correct paging information within a certain period of time, then the end Q1 of sequential pulse generator IC2 exports high level all the time, pin 3 output low levels up to timer IC3, this low level is through the anti-phase high level that becomes of inverter ic 1D, be added to the reset terminal RST of sequential pulse generator IC2 through diode D7, make it to reset the back by Q1 end output low level, then timer IC3 quits work.If before timer IC3 output low level, received second time paging information again, the Q2 of sequential pulse generator IC2 end is exported high level so, this high level makes silicon control T1 conducting after resistance R 7 current limlitings, the electric current of self-contained battery B1 makes optocoupler O1 in-to-in lumination of light emitting diode like this, makes its output conducting.Then power line voltage directly is added in the base stage of aerotron N2 through the mouth e of optocoupler O1, and it is ended, and then relay J discharges, thereby cuts off the high tension supply in the automobile, makes engine off.If the annunciator power supply is artificially cut off, this moment, self-contained battery B1 still kept silicon control T1 conducting, but then guard relay J is in release position, and the guard mode of system is maintained.
Major advantage of the present utility model is: 1. owing to utilize existing Wireless paging information as control signal, Steal the event of robbing in case vehicle takes place, car owner's available phone paging remote annunciator stops working vehicle and sends simultaneously Report to the police, thereby avoided vehicle to be robbed and personal injury; 2. adopt one to one coding and decoding device, make the robber The thief can not remove the guard mode of alarm easily, does not have car owner's the continuous release of special-purpose coding and decoding device, car Can not start, further prevent stolen.
