Background technology
When automobile is placed for a long time, because car load quiescent current exists, cause discharged or defective battery can not start the engine.If pull out storage battery lead-in wire, anti-theft alarm for vehicle work can be affected again.Therefore, fail between anti-theft alarm and storage battery power-off protection in known technology effectively to take into account.Publication date is on 02 13rd, 2008, publication number be CN 201021258 patent document discloses a kind of vehicle anti-theft by name, to driving a car under the influence of alcohol voice alarm control system, this system comprises traffic safety controller, false alarm prevention, warning trigger controller, power alarm controller, anti-robbing automobile, remote control is stopped and is prevented knocking into the back controller, two wires central control door lock controller, wireless voice alarm controller for drunk-driving, remote control transmitter, receiver of remote-control sytem forms, this technical scheme is owing to adopting the embodiment of power-off alarm, storage battery is once dismantled will trigger alarm function, can effectively anti-robbing automobile and effectively preventing drunk driver from driving.But its weak point is just to report to the police immediately after storage battery output loop is cut-off, can not carry out power-off protection to storage battery.
Summary of the invention
Main purpose of the present invention is to provide a kind of power failure anti-theft alarm system, is combined by anti-theft alarm function with power-off protection function.
The present invention is directed to that prior art problem mainly solved by following technical proposals, a kind of power failure anti-theft alarm system, comprising:
Central controller, controls connected parts;
Cut-off relay, its contact is serially connected in storage battery output loop, and its control coil is connected to central controller;
Antitheft coil, receive remote-control key and enter to lock authentication signal, coil output is connected to central controller;
Central controller comprises relay control module, emergency battery, emergency battery charging module, anti-theft alarm module and remote control reception module.
After the car door locking that central controller receives remote-control key and antitheft actuation signal, cut-off relay contact is disconnected, cut off storage battery output loop, the emergency battery be simultaneously arranged in central controller is powered to central controller, enters power cut-off theft-proof alarm condition; During door opening, after central controller checking unlocking signal is legal, open four door locks, now storage battery is not yet connected; When chaufeur enters operator's compartment, remote-control key is inserted ignition lock, and antitheft coil receives key and enters to lock authentication signal and be sent to central controller, after central controller judges that authentication signal is correct, make cut-off relay action, connecting storage battery output loop is that vehicle is powered; When there being any one car door illegally to open, central controller is reported to the police.
Wherein, relay control module provides Control contact for parts such as emergency battery charger, warning circuits.
As preferably, central controller also comprises emergency battery monitoring modular.This monitoring modular is monitored emergency battery, when emergency battery electricity is not enough, automatically the closing of contact of cut-off relay being connected storage battery, is emergency battery charging by emergency battery charging module, after charging reaches setting value, cut-off relay contact disconnects and cuts off storage battery output loop.
As preferably, central controller also connects an antitheft indicator lamp.When central controller enters anti-theft state, make this antitheft indicator lamp flicker.
As preferably, central controller also connects horn trumpet and car light.When there being any one car door illegally to be opened, central controller connects cut-off relay contact, and then connection horn trumpet and car light carry out sound and light alarm.
As preferably, antitheft indicator lamp is semiconductor light-emitting-diode, to save emergency battery energy consumption.
As preferably, wirelessly link between antitheft coil and remote-control key.After remote-control key inserts ignition lock, remote-control key repeater sends wireless authentication signal, and antitheft coil receives this authentication signal and is sent to central controller certification.
As preferably, emergency battery charger is also connected to battery charging plant by relay control module.After the engine started, by battery charge power supply, emergency battery is charged.
The beneficial effect that the present invention brings is; anti-theft alarm function is combined with storage battery power-off protection function; both having solved when automobile is placed for a long time causes discharged or defective battery can not the problem of start the engine because quiescent current exists; do not affect again anti-theft alarm for vehicle normally to work; its circuit structure is simple, easy for installation.
Accompanying drawing explanation
Fig. 1 is a kind of functional block diagram of the present invention.
In figure: 1 is central controller, 2 is cut-off relays, and 3 is antitheft coils, 4 is relay control module, and 5 is emergency battery charging modules, and 6 is emergency batteries, 7 is emergency battery monitoring modulars, and 8 is anti-theft alarm modules, and 9 is remote control reception modules, 10 is remote-control keys, 11 is antitheft indicator lamps, and 12 is car lights, and 13 is horn trumpeies, 14 is storage batterys, and 15 is battery charging plants.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is further described in detail.
Embodiment: as shown in Figure 1, the present invention is a kind of power failure anti-theft alarm system, and central controller 1 connects the control coil of cut-off relay 2, antitheft coil 3, antitheft indicator lamp 11, car light 12 and horn trumpet 13; An open contact of cut-off relay 2 is serially connected in the negative pole output circuit of storage battery 14; Central controller 1 comprises relay control module 4, emergency battery charging module 5, emergency battery 6, emergency battery monitoring modular 7, anti-theft alarm module 8, remote control reception module 9, and CPU, memory device etc.; Emergency battery charging module 5 is connected to the DC output end of battery charging plant 15 by relay control module 4.Wherein, antitheft indicator lamp 11 is semiconductor diode.
Working process:
1) after parking, when remote-control key 10 presses twice car locking key continuously, central controller 1 is by the control coil power-off of cut-off relay 2, and its open contact disconnects, and storage battery 14 negative pole is opened a way; Emergency battery 6 is powered for central controller 1 simultaneously, and antitheft indicator lamp 11 starts flicker, enters anti-theft alarm state.When period, emergency battery monitoring modular 7 detected that emergency battery electricity is not enough, automatically control cut-off relay 2 open contact and close, connect storage battery 14 and charge to emergency battery 6, when charging reaches setting value, disconnect cut-off relay 2 open contact.
2) during remote-control unlocking, after central controller 1 verifies that unlocking signal is legal, open four door locks, now storage battery 14 is not yet connected.When chaufeur enters operator's compartment, remote-control key 10 is inserted ignition lock, in key, repeater wirelessly transmits into lock authentication signal to antitheft coil 3, antitheft coil 3 will enter to lock authentication signal and pass to central controller 1 and carry out certification, judge that storage battery 14 starts power supply by cut-off relay 2 closing of contact correctly.During vehicle travels, battery charging plant 15 charges to emergency battery 6 simultaneously.
3) when there being any one car door illegally to open, central controller 1 connects the energising of cut-off relay 2 open contact car load, and connects car light 12 and horn trumpet 13 carries out sound and light alarm.
So the present invention has following characteristics: by anti-theft alarm function and the perfect adaptation of storage battery power-off protection function; both solved when automobile is placed for a long time due to quiescent current causes discharged or defective battery can not the problem of start the engine; do not affect again anti-theft alarm for vehicle normally to work; its circuit structure is simple, only need change among a small circle and can complete installation on former car basis.
