Background technology
Gate control system is exactly the system of exit and entrance being carried out to control, he carries out strengthening growing up on the basis of conventional door lock, traditional mechanical door lock is only simple mechanical hook-up, no matter how reasonable structural design is, how firm material is, people can be opened it by various means, the passage key management a lot of the people that comes in and goes out is pretty troublesome, key loss needs lock & key to change together, in order to address these problems, there is electronic magnetic card lock, electronic password lock, entrance guard management is made to enter electronic age, but the drawback of these locks is that information is easily replicated, wearing and tearing are large, failure rate is high.Therefore the entrance guard device that urgently a kind of structure is simple, cost is low, convenience is intelligent, effective.
Utility model content
The purpose of this utility model is the deficiency for prior art scheme, provides a kind of entrance guard device based on acoustic communication, has the advantage of simple, with low cost, the convenient intelligence of structure.
For achieving the above object, the technical scheme that the utility model provides is: provide a kind of entrance guard device based on acoustic communication, be made up of gate inhibition's main frame and mobile terminal, described mobile terminal and gate inhibition's main frame are provided with microphone and phonation unit all simultaneously, described gate inhibition's main frame has microprocessor, described microprocessor connects sound wave transmitting element, acoustic receiver unit, display unit, internal storage unit and door lock driver element, carries out two-way alternate communication between described mobile terminal and gate inhibition's main frame based on sound wave.
Described sound wave transmitting element is made up of the D/A converter connected successively, the first amplifier unit and phonation unit.
Described acoustic receiver unit is made up of the AD converter connected successively, the second amplifier unit and microphone.
Described mobile terminal includes but not limited to mobile phone, panel computer or self-defined built-in terminal, and described mobile terminal contains at least one microphone and at least one phonation unit.
Described phonation unit is loudspeaker or hummer.
The beneficial effects of the utility model are, contactless communication is carried out based on sound wave between described mobile terminal and gate inhibition's main frame, apparatus structure is simple, not easy to wear, improve the potential life-span of entrance guard device, utilize sound wave voice signal can also for direct interaction response in communication process, make the more simple intelligent humanized of whole locking and de-locking process, problems such as utilizing the mobile terminal that everybody generally uses, no longer need worry to forget, lose, be damaged, simplifies the operating process of user.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Shown in figure 1, the utility model embodiment provides a kind of entrance guard device based on acoustic communication, be made up of mobile terminal 1 and gate inhibition's main frame 2, described mobile terminal 1 and gate inhibition's main frame 2 are provided with microphone 4 and phonation unit 3 all simultaneously, described gate inhibition's main frame 2 has microprocessor 24, described microprocessor 24 connects sound wave transmitting element 23, acoustic receiver unit 21, display unit 22, internal storage unit 25 and door lock driver element 26, carries out two-way alternate communication between described mobile terminal 1 and gate inhibition's main frame 2 based on sound wave.
Wherein, wherein microprocessor 24 can select STM32F103c6t7, and internal storage unit 25 can select AT45DB161D, is communicated between microprocessor 24 and internal storage unit 25 by I2C, SPI or other communication protocol interfaces; Display unit 22 adopts LCD5110 LCDs, and this liquid crystal display is communicated with microprocessor 24 by SPI or I2C interface; The microphone of acoustic receiver unit 21 adopts general microphone model, and amplifier can adopt TLC072, and AD converter can select AD5340, and AD converter is connected with the I/O port of microprocessor.
Preferably, above-mentioned mobile terminal 1 includes but not limited to mobile phone, panel computer or self-defined built-in terminal, and described mobile terminal 1 is containing at least one microphone 4 and at least one phonation unit 3.
During concrete use, mobile terminal 1 includes the identity information of authentication person, the codec unit of described identity information through mobile terminal inside and D/A converter effect are converted to sound wave simulating signal, and sent out by the phonation unit 3 on mobile terminal 1, acoustic receiver unit 21 on gate inhibition's main frame 2 carries out acoustic receiver by microphone 4, effect through the second amplifier unit 211 and AD converter 212 is converted to digital signal, be sent to microprocessor 24, microprocessor 24 operates and data in comparison internal storage unit 25, realize unlocking or locking, effective information is shown by display unit 22, effective information is encoded to sound wave feedback signal sound wave transmitting element 23 on door access machine 2 simultaneously and is sent to loudspeaker 3 and plays, microphone 4 on mobile terminal 1 receives sound wave feedback signal, obtain feedback information, thus complete a gate inhibition and lock or unlock interactive communication process.
Composition graphs 1, contactless communication is carried out based on sound wave between mobile terminal described in the utility model and gate inhibition's main frame, apparatus structure is simple, not easy to wear, improve the potential life-span of entrance guard device, utilize sound wave voice signal can also for direct interaction response in communication process, make the more simple intelligent humanized of whole locking and de-locking process, problems such as utilizing the mobile terminal that everybody generally uses, no longer need worry to forget, lose, be damaged, simplifies the operating process of user.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
