Abstract

The utility model relates to a speech controlling electromagnetic lock, which comprises an alarming circuit, a sound controlling timing power circuit, a speech storing and recognizing circuit and a flip-flop circuit by depending on a circuit plate provided with a speech controlling circuit. The speech controlling electromagnetic lock is connected to an electromagnetic coil of the electromagnetic lock through an execution circuit of an unlocking relay and converts speech signals conforming to the original state to electric signals after the speech controlling electromagnetic lock compares and recognizes incoming speech signals and pre-stored speech signals, and then the relay is controlled to unlock the electromagnetic lock. Compared with the ordinary electromagnetic lock, the speech controlling electromagnetic lock has the advantages of no need of a key and simple operation and has the functions of safety, theft prevention and alarm.

Description

Voice control electromagnetic lock

The utility model belongs to civilian antitheft series of products, specially refers to the device that utilizes voice control electromagnetic switch.

Speech recognition technology is a new problem of researching and developing energetically in the intellectronics section, and each state can be used for many aspects of social life at present all in continuous further investigation.People's sound is the same with people's fingerprint, have nothing in common with each other, relying on sound to discern each different people is very accurately and reliably, voice recognition controller is exactly the application of this principle, the voice control electromagnetic lock that we succeed in developing is exactly the voice with the people, by the conversion of electronic circuit, become the corresponding signal of telecommunication and control electromagnet in the electromagnetic lock, make its adhesive or disconnection.This lock is installed on door, automotive door, strongbox, cabinet, the drawer, plays good burglary insurance effect.Compared with present existing many dissimilar anti-theft puzzle locks, simple to operate, strong security, safe and reliable.And existing electromagnetic lock, coded lock all needs key, in case leave behind or key loss then can't open, put to no little inconvenience, so people wishes to seek a kind ofly not only to insure but also convenient, need not be with the lock of control voluntarily of key.

The purpose of this utility model is a kind of without key in order to make, but relies on people's voice to control the unlatching electromagnetic lock.

The design relies on following technical proposals to realize that control section is the circuit board [2] that a piece of cloth has the voice control circuit, and it comprises warning circuit part [2.1]; Acoustic control Timing power supply circuit part [2.2]; Voice storage and identification circuit part [2.3], this part comprises a speech chip HM2007 again, flip-flop circuit part [2.4]; The unblank executive circuit part [2.5] of relay, it comprise control triode BUT656 and one carry out relay J ', and link to each other with electromagnetic coil in the electromagnetic lock [3], the power pack of entire circuit plate [1], the battery circuit that is designed to ac buck circuit and reserve combines, and carries out alternating current-direct current dual power supply system.

Further specify embodiment in conjunction with the accompanying drawings.

Description of drawings:

Fig. 1 is voice control electromagnetic lock functional-block diagram;

Fig. 2 is voice control electromagnetic lock circuit board wiring figure;

Fig. 3 is one of embodiment, and electromagnetic lock is used for the inboard state of door on the door;

Fig. 4 is used for outer side of door state on the door for electromagnetic lock.

According to the annexation of circuit among the figure, be divided into five major parts, the power pack of circuit board [1], battery circuit by ac buck circuit and reserve combines, reaching the ability of alternating current-direct current dual power supply, having a power failure or when civil power was disconnected by the robber temporarily, circuit board still can operate as normal.Warning circuit part [2.1] in the circuit board [2], what include normally closed tongue tube G2 and a plurality of parallel connections often opens reed switch relay G3-G5, open the door steathily when locking with the mode of magnet adhesive in outer side of door attempt as the robber, be arranged on the in a single day searched magnet of many places tongue tube in the door circuitous on, just demand working warning circuit, the loudspeaker shriek frightens the robber away or makes the security personnel rush towards the scene and takes measures.Acoustic control Timing power supply part [2.2], connect power supply by the time interval of setting in advance to circuit, be in order when storage voice and preparation are unblanked, just to connect, to be in off-state and save electricity consumption at ordinary times, before the use, knock earlier door-plate gently, by the sound, make the oscillation circuit work of acoustic control timing circuit, immediately automatic power, after being opened, door lock has a power failure immediately again, each supplying time was adjustable at interval, as each power supply 10 seconds, 15 seconds, owner is enough to open door lock, the robber then feels deficiency of time, and in the time of at the appointed time can not be with door-lock opening, timer also can cut off the power supply automatically, this part is provided with, and has also increased the confidentiality and the reliability of lock.Voice storage and identification circuit [2.3], this is voice-operated core, by chip HM2007, can store the prior voice signal of owner, comparison signal when unblanking, when unblanking, when the voice signal that sends and comparison signal are in full accord, just this voice signal is received and converts to electrical signal transfer and give the next stage circuits for triggering, circuits for triggering [2.4] at the appointed time in, order triggers oscillation circuit to the electric signal that receives and produces pulse signal to next stage, when pulse signal receive by the colelctor electrode of triode BUT656 relay J ' after, electromagnet in the electromagnetic lock that adhesive links to each other with it [3], thus lock is opened.The specification of lock can be made difformity according to the needs of different occasions, and size and power during use, also can be designed to the state of confession one people's special use, many people and usefulness, many words and usefulness.

By Fig. 4, to being used for the situation of one of the embodiment on the gate, sandwich-like is made at gate [5], and there is a little dodge gate [4] at the inboard middle part of door, device circuit board [2] in it, power pack [1] is an alternating current-direct current dual power supply system, battery circuit by ac buck circuit and reserve combines the lower position that is placed on door, and the upper right side has aperture in the door, and sound arrives Electret condenser microphone MIC by aperture, top spinosity hole LO in the door, electromagnetic lock [3] is installed in the side of door.

Compared with prior art, speech controlling elecromagnetic lock has following advantages:

1, speech controlling elecromagnetic lock has safe and reliable, strong security than common electrical magnetic padlock, And do not need key;

2, easy and simple to handle, can antitheftly can report to the police again;

3, its employed circuit board small volume and less weight can hiddenly be installed;

4, this facility can be useful for each big hotel guest-room, strongbox, cabinet, automotive door and family gate etc.

Claims

1, a kind of voice control electromagnetic lock partly is made up of control section and conventional electromagnetic lock, it is characterized in that control section is the circuit board [2] that a piece of cloth has the voice control circuit, and it comprises warning circuit part [2.1]; Acoustic control Timing power supply circuit part [2.2]; Voice storage and identification circuit part [2.3], this part comprises a speech chip HM2007 and Electret condenser microphone MIC again, flip-flop circuit part [2.4]; The unblank executive circuit part [2.5] of relay, it comprise a control triode BUT656 and one carry out relay J ', and link to each other with electromagnetic coil in the electromagnetic lock [3], the power pack of entire circuit plate [1] is alternating current-direct current dual power supply system.
