Description

The GSM theftproof lock

Technical field

The utility model relates to a kind of lock class technical field, is specifically related to a kind of GSM theftproof lock.

Background technology

The common electronics lock generally all adopts electronic component and frame for movement structure combining on the market, and control section uses electronic circuit, and executing agency uses electromagnet (micromotor) and lock body.These electronic locks are compared with traditional mechanical door lock, its have strong security, safe, without mechanical key, advantage such as easy to use.At present in the known unlatching executive system based on identification authentication mode, 1, token and password system be owing to rely on safeguard measures such as smart card, identification number, password, there is token lost, copied, is replicated, password easily cracks equivalent risk.In order to improve safety, must increase the complexity of password and password, cause the difficulty in the use.2, adopt the system of biological identification technology, because of using biological characteristic as basis of characterization, need not to remember ID and password, also needn't carry smart card and so on, but its authentication equipment and actuating unit are connected as a single entity, individual privacy (biological information) must be pre-recorded in the common equipment, and not possess common key with the flexible Application function that possesses (as lend etc.).This not only causes infringement to the privacy of user fingerprints, and finger print identifying part damages easily as shared device, and maintenance cost is big.

The utility model content

Technical problem to be solved in the utility model provides a kind of strong security, safe effect is good, flexibility is high and lower-cost GSM theftproof lock.

For addressing the above problem, the GSM theftproof lock that the utility model is designed, comprise executing agency and control section, described control section is mainly by power supply and the GSM communication module that links to each other with power supply, SIM card, the dual-tone multifrequency receiver module, control relay and the micro-control unit module of opening the light constitutes, SIM card and GSM communication module electrically connect, GSM communication module and dual-tone multifrequency receiver module electrically connect, and both are connected to respectively on the micro-control unit module, be connected with the control relay that opens the light on the micro-control unit module, this control relay that opens the light is connected with the automatically controlled end of executing agency.At first accept module and accept the GSM signal that mobile portable phone transmits by SIM card, and through passing to the micro-control unit module by control circuit after the decoding of GSM communication module, after treating micro-control unit module password authentification success, and be that lock body sends various control signals by control circuit.

In order to show the duty of electronic lock intuitively, in such scheme, also be electrically connected with display screen on the described micro-control unit module, and this display screen is connected with power supply.

Also being connected to a register system time on the above-mentioned power supply gets clock chip, and this clock chip is electrically connected with the micro-control unit module, when not opening door lock in setting-up time, makes control circuit send signal, and door lock is locked again.

The utility model also comprises a reserve battery, and this reserve battery links to each other with clock chip, in case system's power down, and in time data are preserved.

The utility model compared with prior art because the corresponding phone number of each password, and password has only the householder to know, so no matter be that the stranger learns password, perhaps obtain householder's mobile phone separately, all can't unblank, through the secondary checking, level security is stronger; In addition, can also be by the improvement of software, continue to increase the complexity of security authentication process or increase various security protections and function such as warning automatically, make it be applied in the field bigger to demand for security, do not need hardware circuit is changed the cost of having saved exploitation greatly and having used like this.

Description of drawings

Fig. 1 is the circuit theory diagrams of the utility model control section.

The specific embodiment

A kind of GSM theftproof lock of the utility model comprises executing agency and control section two large divisions.Executing agency uses micromotor (or electromagnet) and lock body.Control section uses electronic circuit, its circuit theory diagrams as shown in Figure 1, the GSM communication module that comprises power supply and link to each other, SIM card, dual-tone multifrequency receiver module, open the light control relay and micro-control unit module formation with power supply, SIM card and GSM communication module electrically connect, GSM communication module and dual-tone multifrequency receiver module electrically connect, and both are connected to respectively on the micro-control unit module, be connected with the control relay that opens the light on the micro-control unit module, this control relay that opens the light is connected with the automatically controlled end of executing agency.The utility model most preferred embodiment JI port welding system power supply, GSM communication module adopt MC55 chip, dual-tone multifrequency receiver module to adopt HT9170D chip, micro-control unit module to adopt the ATMEGA16 chip to constitute.SIM card is common mobile phone card, and it must be received on the GSM communication module and just can connect to network, and communicates.After SIM card is connected to the GSM communication module,, can realize the function of short breath transmitting-receiving and telephone communication again by the micro-control unit module controls.Micro-control unit modules A TMEGA16 is by serial ports (TXD and RXD) control GSM communication module MC55, and both can intercom mutually.The utility model most preferred embodiment also connects a LED light in order to show the network state of GSM communication module MC55 on the SYNC pin of GSM communication module MC55.The VN pin of dual-tone multifrequency receiver module HT9170D links to each other with the EPN pin of GSM communication module MC55 with the GS pin simultaneously, and this dual-tone multifrequency receiver module HT9170D is used for multisound and double-frequency (DTMF) signal detection.As when incoming call, after the connection, the other side presses certain button of cell phone keyboard, and dual-tone multifrequency receiver module HT9170D just can detect key value, and (PD4～PD7) passes to micro-control unit modules A TMEGA16 processing by FPDP key value.The control relay JK1 pair of contact of opening the light of the utility model most preferred embodiment meets doorway signaling interface J2, is used to drive executing agency's motor and rotates, and realizes opening the door action.

The utility model comprises that also one is the clock chip of the time of register system, and this clock chip is connected with the micro-control unit.In the utility model most preferred embodiment, clock chip adopts the DS1302 chip, and the RST of clock chip DS1302, I/O, SCLK port link to each other with PA3, PA4, the PA5 port of micro-control unit modules A TMEGA16 respectively.Reserve battery BATTERY is connected on the clock chip DS1302, in case data are preserved in the locking system power down.

When the user need open the door, by the cell-phone number of having verified through binding, dial the stored number of the SIM card of depositing in the circuit module, after the closing of the circuit, send a prompt tone by control circuit, this moment, the user was once more by presently used mobile phone, directly input password (forming) by numeral with mobile phone key, again via the control circuit authentication password, after password meets, for the user unblanks.After the user entered, control circuit was given signal of electronic lock body again, allows door lock automatically lock.Because the corresponding phone number of each password, and password has only the householder to know, so no matter be that the stranger learns password, perhaps obtains householder's mobile phone separately, all can't unblank, and through the secondary checking, level security is very strong.
