Description
Technical field
The present invention relates to a kind of warning, especially a kind of vehicle-mounted lock controlled anti-theft warning system based on bluetooth module.
Background technology
The development that the type of automotive theft proof system is maked rapid progress along with science and technology, in order to tackle robber driver's section of constantly change, people develop the antitheft equipment of structure of all kinds.Current, four large classes can be divided into by its structure: electromechanical, mechanical type, electronic type, network type.Its principle of work is connected on automobile circuit by Car Burglar Alarm, thus prevent automobile stolen to reach, and protection automobile is not damaged, the object of the various functions of theft.
Electronic type anti-theft system in current automobile burglar, all need additionally to carry a signal projector for unlocking, after electron key is lost, the safety of vehicle can not get ensureing, and its system architecture is complicated, and cost is higher.
Summary of the invention
The object of the invention is to: a kind of vehicle-mounted lock controlled anti-theft warning system based on bluetooth module is provided.
The technical solution used in the present invention is as follows:
Based on a vehicle-mounted lock controlled anti-theft warning system for bluetooth module, comprise the door lock circuit, one-chip computer module, bluetooth module, the Anneta module that connect successively, power module is powered to the whole warning device that is put into by connecting onboard power system.
Concrete, use IC chip TWH8751 in door lock circuit.Door lock circuit structure is: NAND gate U1 input end 1 is connected to VCC by resistance R2, also successively by connecting electric-controlled switch S1, switch S 3, switch S 2 is connected to the input end 2 of NAND gate U1, the input end 2 of NAND gate U1 is also connected to VCC by resistance R3, the mouth of NAND gate U1 connects the input end 1 of NAND gate U2, the mouth of NAND gate U2 connects the input end 1 of NAND gate U3, the mouth of NAND gate U3 connects the input end 2 of NAND gate U2 and the pin 2 of IC chip U4 respectively, the input end 2 of NAND gate U3 connects VCC by resistance R1, the input end 2 of the U3 of NAND gate connects electric capacity C2 by electric-controlled switch S4, resistance R5, VCC is connected after annunciator LS1, the input end 3 of NAND gate U3, by resistance R4 to VCC, is also connected to the pin 3 of integrated chip U4 by electric capacity C1, the pin 5 of integrated chip U4 is connected to VCC, connects electric capacity C2 between pin 3 and pin 1, pin 1 and pin 4 contact resistance R5.Electric-controlled switch S1 with S4 in door lock circuit is connected with the I/O of one-chip computer module respectively.Control electric-controlled switch S1 through one-chip computer module after bluetooth module receives the information of shutting to disconnect, there is abnormal disconnection in the arbitrary equipment be now connected with S3 as switch S 2, then NAND gate U1 input end 1 is high level, it exports as low level, in the rest-set flip-flop that NAND gate U2 and U3 is formed, the output of NAND gate U3 is low level, the triggering oscillator that integrated chip U4, electric capacity C2, resistance R5 are formed starts concussion, annunciator LS1 is worked and gives the alarm.During closed automatically controlled switch S 4, rest-set flip-flop is reset, and oscillator quits work, and switch S 2 and S3 connecting device can arbitrarily use.During warning, closed automatically controlled switch S 4, by rest-set flip-flop, is that the energy that the pin 2 of integrated chip U4 can be consumed in oscillator by electric capacity C1 rapidly for low level makes warning stop.
Concrete, Anneta module adopts SAW resonator.Antenna module structure is: antenna E1 connects the collecting electrode of NPN aerotron Q1 by electric capacity C3, the grounded emitter of aerotron Q1, the collecting electrode of aerotron Q1 is connected to VCC by variable inductance L1, SAW resonator Y2 is connected with between the base stage of aerotron Q1 and the control end of variable inductance L1, the control end of variable inductance L1 is by electric capacity C4 ground connection, the base stage forward of aerotron Q1 connects diode D1, and diode D1 is parallel with resistance R6, the mouth of diode D1 and the connection of bluetooth module.Relative to LC oscillator, adopt the circuit working of SAW resonator highly stable, transmitting frequency all can not drift about.
Native system controls system by Bluetooth of mobile phone, accepted by Anneta module after transmitting, be sent to one-chip computer module after bluetooth module process, one-chip computer module controls electric-controlled switch, the mode of operation of further control gate lock circuit, and power module connects vehicle power to system power supply.This system can get the special key projector of band with mobile phone, and mobile phone repeatedly can be encrypted signal, and safety is higher.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: eliminate key projector, structure is simple, and reliability is stronger, safer.
