Abstract
The utility model designs a circuit by using a cell phone blue tooth to automatically switch on and off locks, and the circuit belongs to the automatic control field. The circuit comprises a blue tooth module, a monolithic machine, a drive circuit and a control circuit, wherein the blue tooth module is connected with the monolithic machine which is connected with the drive circuit, and the drive circuit is connected with the control circuit to move. The circuit is capable of solving the problems of disturbance and replication of general electronic locks, is safe and reliable, and uses the blue tooth function owned by the cell phone, the cell phone is used to serve as 'electronic key', the circuit simplifies equipment and provides convenient utilization.
Description
Technical field:
The utility model belongs to the technology of a kind of robotization control, is meant that especially a kind of identity recognition function that utilizes Bluetooth of mobile phone carries out the application circuit of robotization gauge tap to electric locksets such as control and garage gate in the automobile.
Background technology:
Occasions such as nowadays the remote control control technology is widely used in controlling in gate inhibition, the automobile.The common technology person of being to use need carry a radio generator in addition, and this generator transmits, and after being installed in identification equipment on automobile or the door and receiving signal, takes action passively, is exactly out usually or closes.
Utilize the shortcoming of the equipment of this method principle manufacturing to be: 1, the person of being identified (user just) need carry the transmitter (just usually said ' electron key ') of pairing in addition, and under summer this clothing condition, pocket is less, and is very inconvenient; 2, all be the execution action of passive-type, must the person of being to use carry out corresponding operating after, could carry out corresponding actions, such as pressing generator upward-acting door or door close button; 3, poor anti jamming capability, owing to be to be operated in constant fixed frequency all, mutual interference is very obvious, and extensive along with what use, the phase mutual interference is more and more, and reliability becomes worse and worse.4, poor stability, existing identification equipment repetition rate of coding height is intercepted and captured easily, is replicated easily.In the automotive lock industry, " lock interference unit " and " remote signal demoder " appearred, and be used to disturb the work of automobile door lock by the lawless person, or intercept others transmitting, carry out criminal activity.
Also have a kind of automated intelligent key that adopts the intelligent RF technology on high-grade automobile, it also has automatic switch car door function.But it still is operated on the fixed frequency, is disturbed easily; Still need be equipped with and carry special identity recognizer.
Summary of the invention:
The utility model is exactly in order to overcome the shortcoming of prior art, invented the circuit that a kind of identity recognition function that utilizes Bluetooth of mobile phone (Bluetooth) carries out automatic control lock, not only realized safe, antijamming capability is strong, and accomplish automatic control, do not need the user to take any action.Utilize existing bluetooth cellular phone extensively to popularize these characteristics simultaneously, the user need not acquire, carry extra signal generator.
This circuit is by containing bluetooth module, single-chip microcomputer, driving circuit and control circuit, and bluetooth module is connected to single-chip microcomputer, and single-chip microcomputer is connected to driving circuit, and driving circuit connects control circuit and moves.This circuit adopts universal standard components and parts, bluetooth module 3.3V power supply power supply, single-chip microcomputer 5V power supply power supply, driving circuit and control circuit 12V power supply power supply.
In order to save the mobile phone power consumption, reduce unnecessary Bluetooth signal transmitting-receiving, carry out closing Bluetooth system in the identification not needing, while successively works and reduction of service life in order to prevent bluetooth module, imponderable non-systemic mistake perhaps occurs, driving circuit connects a 12V relay in addition, and this relay is connected to bluetooth module, be used for controlling bluetooth module power supply, reach and stop bluetooth module work or power-off restoration.
The utility model is based on Bluetooth technology, because Bluetooth transmission is used spread spectrum, frequency hopping, data encryption and globally unique 48 bit address identification codes have been avoided interference most possibly, duplicated, and are safe and reliable.On the other hand, the Bluetooth function that has utilized mobile phone to carry serves as transceiver i.e. " electron key " with mobile phone, has simplified equipment, and is easy to use.
Description of drawings:
Fig. 1 is a circuit block diagram of the present invention.
Embodiment:
A specific embodiment of the circuit of the present invention that shows according to Fig. 1 is made of bluetooth module 1, single-chip microcomputer 2, driving circuit 3 and control circuit 4, and bluetooth module 1 can select for use the CSR Bluetooth chip to add peripheral circuit, adopts the power supply of 3.3V reference power supply; Single-chip microcomputer 2 select for use 51 family chips or PIC series can, the power supply of 5V power supply; Driving circuit 3 selects for use 2003 chip for driving to add that general peripheral circuit constitutes, and control circuit 4 is actuating of relay circuit, controls the break-make of peripheral circuit to realize automatic control by the actuating of relay.Driving circuit 3 and control circuit 4 are powered by the 12V power supply.
System also is provided with memory deletion and relearns memory button 5, and this memory is deleted and relearned memory button 5 and be connected with bluetooth module 1.Make things convenient for the user to change the pairing mobile phone.
Do unnecessary continuous working for fear of bluetooth module, and detect under the abnormal situation of bluetooth operating mode at single-chip microcomputer 2 and to carry out the active power-off restoration.Driving circuit 3 connects a 12V relay 6, is used for controlling the power supply of bluetooth module 1.
