Abstract
The utility model discloses a self-defense type anti-theft device with very-long-distance for a vehicle, which belongs to the field of an anti-theft device. The utility model is characterized in that an anti-theft control circuit is formed by connecting a power supply voltage stabilizing circuit and a wireless receiving and decoding circuit to control a switch circuit to switch on and switch off, an executing alarm circuit is controlled to generate high voltage so as to prevent a vehicle from being stolen and alarm signals are sent out. The utility model has the advantages of simple circuit structure, convenient operation and high anti-theft performance. After the vehicle is stolen, an ignition device of the vehicle can be cut off through signals sent out by a wireless paging station to close in a forcing mode the vehicle. Meanwhile, alarm sounds with high loudness are sent out, so the stolen vehicle is convenient to look for.
Description
The utility model relates to a kind of anti-theft device for vehicle, relates in particular to a kind of super long distance self-defence formula anti-theft device for vehicle.
Along with people's living standard improves constantly, automobile has entered huge numbers of families, and brings great convenience to people's life, work and travelling.But the stolen phenomenon of automobile happens occasionally in society, and brings great loss for people's lives and properties, and therefore, alarms and security systems for automobiles produces thereupon.At present, the anti-theft device for vehicle of inventing on the market mostly is touch and induction type, when the people touches automobile or when automobile was very near, touch or induction type anti-theft device for vehicle just can send alerting signal, reminds the car owner to enhance your vigilance.But, as long as just the car alarm that has have the people near or the vibration vehicle can give the alarm, very easily produce misoperation, also increased simultaneously robber's vigilance, thereby disguised low, anti-theft device for vehicle is easily destroyed.In case and vehicle is stolen then be difficult to recover, as run into the life that the robber plunders vehicle drivers will be dangerous more, protective potential is poor.
The purpose of this utility model just is to provide a kind of super long distance self-defence formula anti-theft device for vehicle, and utilizes radio call to transmit tie as signal, makes vehicle close ignition device by force, prevents that vehicle is stolen.
For achieving the above object, the utility model can be realized by following scheme: the utility model comprises housing, power supply and theft-proofing control circuit, be provided with power supply stabilization circuit in the theft-proofing control circuit, theft-proofing control circuit is electrically connected and master cock circuit turn-on and disconnection by wireless receiving decoding circuit and photoelectricity coupled circuit, carry out warning circuit during the switch circuit conducting and produce high pressure and make the robber in operator's compartment, handle automobile and send alerting signal, be connected to the connecting and disconnecting of relay CJ Control of Automobile firing circuit at the mouth of switch circuit.Carrying out warning circuit is to be in parallel by relay CJ, warning circuit and high voltage circuit to be connected on the mouth of switch circuit.
The utility model has the advantages that: circuit structure is simple, components and parts are little, cost is low, and is easy to install, has high pressure and warning dual-use function, anti-theft is strong, because utilize the extremely wide paging network of protection face to transmit tie, therefore has super long distance theftproof performance, as long as stolen vehicle is in the scope that paging network covers as signal, no matter where car is reached, can make stolen vehicle difficult to move even one step.
The drawing explanation:
Accompanying drawing 2 is the utility model electrical schematic diagrams.
Now with specific embodiment the utility model is described in further detail in conjunction with the accompanying drawings:
The utility model comprises housing, power supply and theft-proofing control circuit, is provided with power supply stabilization circuit (1), wireless receiving decoding circuit (5), photoelectricity coupled circuit (4), switch circuit (2) in the theft-proofing control circuit and carries out warning circuit (3).Power supply stabilization circuit (1) is made of three terminal regulator IC1, IC2 (LM317) and peripheral cell resistance, electric capacity and diode, input voltage is 12-24V, and supply wireless receiving decoding circuit (5), photoelectricity coupled circuit (4) and switch circuit (2) voltage (IC5:TWH8778) are respectively 1.4V, 6V and 6V.Wireless receiving decoding circuit (5) is made of special-purpose paging receiver A1, is electrically connected by photoelectricity coupled circuit (4) and switch circuit (2).The voltage that is provided with 6V at switch circuit (2) mouth is supplied with execution warning circuit (3), and execution warning circuit (3) is in parallel by relay CJ, warning circuit A3 and high voltage circuit A2 and constitutes.In use set earlier and open password and close password.When opening password by the input of mobile paging platform; code signal after paging centers modulation to aerial emission; in the wireless receiving decoding circuit (5) special-purpose paging receiver A1 receive signal after decoding be identified as actuation signal after; positive pulse of 1 pin output of special-purpose paging receiver A1; positive pulse of 3 pin output by photoelectrical coupler IC3 in the photoelectricity coupled circuit (4) makes 5 conductings of switch ic chip and maintenance in the switch circuit (2); relay CJ gets electronic work and cuts off the vehicle ignition circuit; close vehicle by force; carry out the middle annunciator A3 of warning circuit (3) simultaneously and send the loudness chimes of doom; high voltage circuit A2 gets electric through 10 seconds time-delay back generation high-tension currents; make the robber drive in-house operation (10 seconds, time-delay was design-calculated in order to protect the car owner) at this moment; this device automatically locks, and has only to close password by paging centers input and this device could be closed.When 2 pin of special-purpose paging receiver A1 were exported positive pulse, 4 pin of photoelectrical coupler IC4 became low level, and switch circuit (2) cuts out, and carried out warning circuit (3) and quit work.
Claims (2)
1. super long distance self-defence formula anti-theft device for vehicle, comprise housing, power supply and theft-proofing control circuit, be provided with power supply stabilization circuit (1) in the theft-proofing control circuit, it is characterized in that: theft-proofing control circuit is to be electrically connected and (2) conducting of master cock circuit and disconnection by wireless receiving decoding circuit (5) and photoelectricity coupled circuit (4), carrying out warning circuit (3) generation high pressure during switch circuit (2) conducting makes the robber can't handle automobile in operator's compartment, and send alerting signal, be connected to the connecting and disconnecting of relay CJ Control of Automobile firing circuit at the mouth of switch circuit (2).
2. super long distance self-defence formula anti-theft device for vehicle as claimed in claim 1 is characterized in that: carrying out warning circuit (3) is to be in parallel by relay CJ, warning circuit A3 and high voltage circuit A2 to be connected on the mouth of switch circuit (2).
