Abstract

The utility model discloses an electric lock opened by dialing a telephone. The principles are as follows: a call of a telephone line 1 is analyzed by a number analytic circuit 2 and judged by an identification part 4 of door opening request in a CPU 3 to make sure whether the signals from a sensor 5 of door opening request are send or not; if the signals are not send, a control relay 6 is pulled into a telephone 7 for talking; if the signals are send and in conformity with the door opening request setting previously stored in an EEPROM 8, the call number is compared with the door opening request setting previously stored in the EEPROM 8 through a number identification part 9; if the call number is in conformity with the door opening request setting, a driving circuit 10 of opening command drives a motor 11 in the lock to conduct an opening action; if the number of the call is not in conformity with the door opening request setting, the number of the call comes into a password identification part 12 to be checked before opening.

Description

Opening by telephone formula electric control lock

Technical field

The utility model relates to a kind of electric control lock, and is particularly a kind of by putting through the electric control lock of opening by telephone.

Background technology

Present electric control lock comprises Fingerprint Lock, retina lock, DNA lock, magnetic card (1C card) lock, coded lock, wireless (infrared rays) lock etc.First three kind mode of unblanking has not reproducible, the advantage that fail-safe is strong, and the feature of unblanking is unlocking person and innately possesses, do not exist carry, problem such as loss, belong to advanced at present lock kind.But owing to reason such as with high costs, be difficult to popularize, be mainly used in senior departments such as security.Several lock lower costs in back are used more generally, but have some shortcomings, and mainly be: the mode of unblanking is reproducible, and fail-safe is not strong; Except that coded lock, must carry the utensil of unblanking, convenient inadequately and the loss secret worry arranged.It is exactly to suffer malicious sabotage easily that above lockset also has a common shortcoming.

A kind of telephone remote control technology is arranged at present, can realize utilizing phone to control the open and close of lock, its operating principle mainly is to connect a control circuit by telephone line, and utilizes operation telephone keypad input password by authentication, then imports corresponding control routine and realizes unlock operation.But still there are some defectives in this scheme: 1. must connect telephone line, the calling party has produced telephone charge; 2. the operation sequence complexity is convenient inadequately.

Summary of the invention

The purpose of this utility model provides a kind ofly needn't additionally be carried as special-purpose unlocking tools such as keys and can unblank, and simultaneously safe and reliable, the mode of unblanking is not reproducible, does not subject to malicious sabotage, and is with low cost again, do not produce the lockset of cost of use.

The purpose of this utility model realizes as follows:

This electric control lock utilize telephone number uniqueness and with it as the identification foundation.Open by mistake lock and other people utilize this telephone malice to unblank for preventing that the preset number telephone from calling at its place, setting up the request identification of opening the door, have only both equal compliant parties to carry out and unblank.

This electric control lock is made up of automatically controlled lock body and control circuit two large divisions, and automatically controlled lock body adopts common, and control circuit mainly is made up of open the door request identification circuit and incoming call number analysis, identification circuit.Its operating principle is: have under the prerequisite of the request of opening the door in the request identification circuit judgement of opening the door, whether the identification caller ID is default authorization unlocking number, conforms to then to provide and instructs the driving lock body to make unlocking action, otherwise refused.

The request identification circuit that opens the door can adopt key switch formula, human body induction type, infrared induction, photoelectric induction type, acoustic control induction type etc.

The utility model has the advantages that: because mobile phone is very universal now, needn't additionally carries again and can unblank as special-purpose unlocking tools such as keys, extremely convenient; Telephone number has uniqueness and not reproducible, with its as identification according to reliable; Unlock operation needn't be connected phone, does not produce telephone charge; This is locked in outdoors can install any door opener, does not subject to malicious sabotage.Simultaneously with low cost again, be easy to popularize.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Description of drawings

Fig. 1 is the utility model operating principle block diagram.

Fig. 2 is the utility model embodiment electrical schematic diagram.

The specific embodiment

As Fig. 1, when telephone wire 1 has incoming call, check numbers through number parser circuitry 2 earlier and resolve, judge the door request signal that has or not to come self-opening door request sensor 5 by the request of the opening the door identification division 4 in the central processor CPU 3 then, as not having, then telephone 7 is connected in control relay 6 adhesives, realizes the normal talking function; If any, then with random access memory EEPROM8 in the request of opening the door that prestores set and to contrast, do not refused if be inconsistent then, if conform to then by number identification division 9 will be through resolving caller ID and random access memory EEPROM8 in the array number that prestores contrast, then instruct the interior motor 11 of drive circuit 10 driving lock bodies of unblanking to make the action of opening the door if conform to; Then do not enter password identification part 12 if be inconsistent, and connecting incoming call provides prompt tone, keys in unlocking cipher by caller phone, through with EEPROM8 in the password that prestores contrast, the motor 11 that the then instruction that conforms to is locked in the drive circuit 10 driving lock bodies is made the action of opening the door, otherwise is refused.The purpose of setting up password identification part is to prevent just in case door can't be opened because of reasons such as communication network cause incoming call number recognition failures, and a back benefit measure of establishing, to improve reliability.

As Fig. 2, CPU3 adopts single-chip microcomputer, and the request sensor 5 that opens the door can adopt human body induction type, infrared induction, photoelectric induction type, acoustic control induction type etc., is the prior art of mature and reliable with upper type, does not repeat them here.Simple, reliable key switch formula that present embodiment adopts is utilized two key switches to be combined into a simple binary coding and is realized the request of opening the door.Number parser circuitry 2 is made up of integrated circuit U 3 and peripheral cell.8 is random access memory EEPROM.Triode Q in 6 will amplify the adhesive of rear drive relay from the control signal of singlechip CPU 3PRO2 end and connect telephone.10 is motor-driven integrated circuit U2, receives the motor 11 that drives in the signal rear drive lock body from singlechip CPU 3 and makes the lock action of opening the door.For improving the utility model safety, the request of opening the door can be provided with secret signal, as the key switch formula that present embodiment adopts, can work out out a simple binary coding; Touching induction end when human body induction type can be set in the N time ringback tone, other can adopt similar fashion.

The utility model is applicable to dwelling house, office, safety cabinet, safe deposit box, hotel guest room etc.
