Description
Technical field
The utility model relates to a kind of anti-joyride device of vehicle, relates in particular to a kind of digital anti-theft device of vehicle.
Background technology
Nowadays, vehicle quantity such as automobile and motor bike are more and more, and the pilferage behavior of automobile also rolls up thereupon, has caused very big loss to the car owner.Though people have adopted a lot of countrmeasures, for example install antitheft alarm system, install crash-resistant anti-theft column lock, even there have more advanced GPS (Global Position System) to be used for to be antitheft, but these measures all there is shortcoming separately, as antitheft alarm system, too sensitive, be easy to start, make people all be accustomed to automobile and report to the police without reason, can't really play antitheft effect, and anti-theft column lock neither too big obstacle for many car thiefs, and is too high as for the GPS (Global Position System) price, and system is too complicated, not easy to operate, and easy break-down, and general remote control anti-theft device adopts analog signal, is easy to crack, as for some other anti-theft measure, also each have their own shortcoming.Therefore, need a kind of effective and cheap, simple anti-joyride device on the market.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of digital anti-theft device of vehicle, can solve prior art problems, can prevent effectively that vehicle is stolen, and simple in structure and cost is cheap.
The utility model is a kind of digital anti-theft device of vehicle, comprise a projector and a receptor, its internal circuit adopts radiodigital scrambled signal transmission system, projector comprises four buttons, be respectively the switch of control transmitter power, control emission oil circuit is opened the switch of code signal, the control transmission circuit is opened the switch of code signal and the switch that the control emission disconnects oil circuit and circuit code signal, receptor have three leads respectively with power supply, the oil circuit switch, contactor links to each other, and respectively it is carried out switch control according to the difference of received signal.One light-emitting diode is arranged on the launcher shell.Receptor can be installed in the hidden and firm position of vehicle.
The beneficial effects of the utility model are to have adopted the digital encryption coding, password is set with device, can't change, and be difficult to crack, make Long-distance Control safer, by being installed in the hidden and firm position of vehicle, survivable, and the switch of energy control oil channel and circuit, double anti-theft is even have key or pinch off control line also can't start vehicle, and also can make its auto shut down under steam, add and adopt remote sensing control, the opening and closing of control vehicle a long way off, the vehicle anti-theft performance is better, and it is safe and reliable, simple in structure, cheap, be applicable to various power actuated vehicles.
Description of drawings
Fig. 1 is the external structure of a kind of embodiment of this utility model projector;
Fig. 2 is the configuration diagram of a kind of embodiment of this utility model receptor.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
The digital anti-theft device of vehicle of the present utility model is made up of a projector 10 and a corresponding with it receiver 20 that uses.Projector is adorned 10 and is located in the portable anti-flaming plastic casing, and there is the hollow region of packed battery at the shell back side, and projector has a plurality of buttons, four buttons are arranged in the present embodiment, there is a light-emitting diode 11 the shell top, and button 1 is the on ﹠ off switch of projector, when pressing, the projector energized, light-emitting diode 11 shinny indications are switched on, click the projector power cut-off again, light-emitting diode extinguishes indication and cuts off the power supply, and projector is not worked; Button 2 is the oil circuit control key, and when pressing, projector sends one group of digital coding through encrypting, and sends to the unlatching of receptor with control oil channel; Button 3 is the circuit control key, and when pressing, projector sends the digital coding of another group through encrypting, and sends to the unlatching of receptor with the control vehicle circuit; Button 4 is an off switch, sends one group of digital coding through encrypting when pressing again, sends to receptor so that the oil circuit of vehicle and circuit all disconnect.Certainly except that present embodiment, also can adopt 2,4 two buttons, 3,4 two buttons, 2,3,4 three buttons, and 1,2,4 three button, 1,3,4 three multiple array mode such as button also can play enough anti-theft effects.The projector internal circuit adopts radiodigital scrambled signal transmission circuit commonly used.
The receptor 20 of corresponding use with projector comprises a plastic casing, and corresponding radiodigital decoded signal acceptor circuit is equipped with in inside, and the digital signal that receives is decoded, and is converted into electric signal.Its circuit comprises a power lead 21 toward being circumscribed with three leads, receives on the vehicle accumulator or thinks on other power supplys that receptor provides working power; Other comprises an oil circuit control line 22, controls a switch 6, and switch 6 is connected with the high-tension coil 23 of vehicle motor, switch is in off-state at ordinary times, even key is arranged, vehicle also can't start, when it receives the digitally encoded signal that requires the unlatching oil circuit, receptor transfers digital signal to electric signal, connect electromagnet 24 power supplys, make switch 6 be subjected to the magnetic attraction closure, perhaps other usual ways make switch closure, vehicle oil way is connected, and can light a fire by key; This receptor comprises a circuit controling line 25 again, control a switch 7, switch 7 is connected with the storage battery start-up circuit 26 of vehicle, switch is in off-state at ordinary times, and when it received the digitally encoded signal that requires open circuit, receptor transferred digital signal to electric signal, connect electromagnet 27 power supplys, make switch 7 be subjected to the magnetic attraction closure, perhaps adopt other usual ways to make switch closure, the vehicle circuit is connected; And when receptor is received the digitally encoded signal that requires cut off and oil circuit, receptor transfers digital signal to electric signal, cut-off switch 6,7 each self-corresponding electromagnet power supply 24,27, magnetic force disappears, switch 6,7 recover off-state, circuit again, oil circuit all disconnects, and vehicle can't start, even also can make its auto shut down in just travelling, and this receiving device can be installed in the firm positions such as car chassis crossbeam, and is welded, and makes its permanent fixation, the thief is difficult to remove at short notice, even and cut off three control lines of receptor, switch 6,7 not influenced by magnetic force, still disconnect, vehicle still can't start, thereby can be antitheft effectively.
