At the shortcoming of wired tamper box in the prior art, the invention provides a kind of wireless lock oil-electricity system.As shown in Figure 1, wireless vehicle mounted lock oil-electricity system 100 of the present invention is by a remote-control anti-theft main frame 300 (comprising high frequency receiving end and low frequencies end), a remote control transmitter 200 (high-frequency emission end) and the oily electrical nodes 401,402 of a plurality of lock ... 40n (low frequency receiving end) forms.Wherein, the frequency range of high-frequency signal can be 300MHz-900MHz, as preferably can being 315MHz or 433MHz.The frequency of low frequency signal is 125KHz.
Fig. 2, Fig. 3, Fig. 4 show remote control transmitter 200 in the wireless vehicle mounted lock oil-electricity system of the present invention, remote-control anti-theft main frame 300 respectively and lock the formation synoptic diagram of oily electrical nodes 400.
As shown in Figure 2, the remote control transmitter 200 in the wireless vehicle mounted lock oil-electricity system of the present invention is provided with input button 202, scrambler 204 and high-frequency emission module 206.Wherein, can comprise oil/circuitry cuts, turn-on power loss button in the button 202, when this button of pressing, by coded signal that has id information of scrambler 204 outputs, this coded signal is handled the back by high-frequency emission module 206 and is outwards launched with the form of high-frequency wireless signals.
As shown in Figure 3, the remote-control anti-theft main frame 300 in the wireless vehicle mounted lock oil-electricity system of the present invention comprises high frequency receiving circuit 302, first signal processing circuit 304 and low frequencies circuit 306.Wherein, high frequency receiving circuit 302 receives remote control transmitter 200 high-frequency signal that sends (first frequency) and carries out front-end processing and is sent to then in first signal processing circuit 304.First signal processing circuit 304 is decoded and ID identification to the received signal, and outputs a control signal to low frequencies circuit 306 according to result.Based on this control signal, low frequencies circuit 306 is to the oily electrical nodes emission of lock low frequency signal (second frequency), with the cut-out/connection of control lock oil electric switch circuit.
As shown in Figure 4, the oil of the lock in the wireless vehicle mounted lock oil-electricity system of the present invention electrical nodes 400 comprises low frequency receiving circuit 402, secondary signal treatment circuit 404 and on-off circuit 406.After 402 pairs of low frequency signals that receive of low frequency receiving circuit are handled, to secondary signal treatment circuit 404 output signals.According to the signal that receives, secondary signal treatment circuit 404 sends control signal to on-off circuit 406, the cut-out/connection of control lock oil electric switch circuit.
Fig. 5 is the schematic diagram of anti theft host medium and low frequency radiating circuit part according to an embodiment of the invention.In the present embodiment, having adopted model in the low frequencies circuit is the high-power driving chip of TC4421, uses inductance L 1 and capacitor C 2 to form the LC oscillatory circuit, the low frequency signal of emission 125Hz.
Fig. 6 is circuit theory diagrams of locking oily electrical nodes according to an embodiment of the invention.As shown in the figure, in the present embodiment, the secondary signal treatment circuit comprises U2, select for use the MICROCHIP public affairs can model be the single-chip microcomputer of PIC16F57.Comprise U3 in the low frequency receiving circuit, adopting model is the AFE (analog front end) device of MCP2030, and it finishes the reception of the oily electric signal of lock (low frequency signal).U4 is a power-switching circuit, finish+12V is to the VCC conversion.
Resistance R 1, resistance R 2, resistance R 3, resistance R 4, NPN triode Q1, PNP triode Q2 and relay K are formed on-off circuit.Wherein, the base stage of NPN triode Q1 links to each other with an output terminal of described second treatment circuit by the 3rd resistance R 3, the emitter of NPN triode Q1 and described second treatment circuit another output terminal link to each other, the 4th resistance R 4 is connected between the base stage and emitter of NPN triode; The collector of NPN triode links to each other with the base stage of PNP triode Q2 by first resistance R 1, the collector of PNP triode Q2 is by second resistance R, 2 ground connection, the emitter of PNP triode Q2 links to each other with the input end of relay K, and another input end of relay K links to each other with the 12V power supply.Its principle of work is that Q1, Q2 form the servo circuit of lock oil electricity.After secondary signal treatment circuit (being U2) sends the oily electric signal of lock (being the CUTOIL1/CUTOIL2 switching signal), after the Q1/Q2 driving, drive servo relay K again, the normally closed point of K is disconnected, thereby finish the oily electric work energy of lock.
In the wireless vehicle mounted lock oil-electricity system of the present invention, the remote-control anti-theft main frame has power frequency radio signal receiving function, can receive the instructions such as setting up defences and withdraw a garrison that remote control transmitter sends.After the remote-control anti-theft main frame receives the signal of setting up defences that the car owner sends, promptly can send the instruction of lock oil electricity to each node, like this, automobile will run out of steam and can't start.When the car owner sends when withdrawing a garrison signal, the remote-control anti-theft main frame will send unlock command, and automobile recovers power.
The remote-control anti-theft main frame is the oily electrical nodes of a plurality of locks of low frequency signal remote control of 125Khz by frequency range, and the communication between them is unidirectional.Present most of wireless remote control product can only adopt the radio signal (300Mhz-900Mhz) of power frequency scope.It is far away that this frequency range has transmitting range, characteristics such as signal penetrability difference, and, therefore be easy to be subjected to extraneous co-channel interference because most of wireless products all adopt this frequency range, perhaps be subjected to the malice co-channel interference of cartheft, cause the temporary transient inefficacy of wireless tamper lock oil-electricity system.And the radio signal of low frequency 125K is compared with the power frequency radio signal, has characteristics such as penetrability height, spatial transmission power attenuation be big., decay big shortcoming in the application of wireless tamper lock oil-electricity system, but become advantage.The installation site is limited in the car between the end owing to transmit and receive, and therefore the remote control distance of wireless tamper box only needs so also can not cause co-channel interference to other products in the scope of 2 meters of radiuses.
