[0001] The present invention relates to the field of electronic information technology, and in particular to an access lock control method and system based on two-way interaction of sound wave / voice communication. Background Art

[0002] In the era of rapid development of the Internet and mobile communication technology, people have a higher quality pursuit of life and environment, and have extremely high food safety and living environment safety in terms of food, clothing, housing and transportation. Especially in cities with a huge floating population, ordinary door lock systems and manual access management have low access security and inconvenience in housing management for tenants, and do not utilize grid system management.

[0003] The current access control system is roughly divided into two categories: no network and network communication control. The first category is no network: keyboard password, magnetic card electronic induction, fingerprint and other methods. This type of access control password, magnetic card, etc. cannot achieve the uniqueness of the magnetic card, the password is easy to leak, be cracked, and the magnetic card is easy to be copied. For example, the second-generation ID card and residence permit ID are highly unique, but the reader is relatively expensive, the carrying cost is high, and it is easy to lose. The fingerprint ID recognition accuracy is low and requires multiple recognitions; the experience is poor, and it cannot ensure the identity of the door opener, is not convenient for digital network precision management, and is not convenient for accurate collection of information on the inflow and outflow of the floating population. The second category is network communication (wired network, WIFI, Bluetooth, GPRS) and other methods, all of which have extremely high network requirements, immature compatibility and stability, high cost, high maintenance cost, low security, and high cost of use, which makes it impossible to popularize and meet the needs of accurate information collection and systematic and efficient management of the floating population.

[0004] Therefore, the prior art has defects and needs to be improved. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a method and system for controlling an access lock based on two-way interaction of sound wave / voice communication with a high security by two-way interaction between an access control system and a mobile communication terminal.

[0007] Applied to the above technical solution, in the access lock control method: the DSP processor is internally provided with a first amplifier connected to the loudspeaker, and a second amplifier connected to the microphone; the first verification code and the access control ID are amplified by the first amplifier and then sent out through the loudspeaker; the second verification code and the user ID are collected by the microphone and amplified by the second amplifier for verification.

[0008] Applied to each of the above technical solutions, in the access lock control method: the first verification code and the second verification code are the same verification code; or, the second verification code is generated by calculation based on the first verification code.

[0009] Applied to the above-mentioned technical solutions, in the access lock control method: in step S2, after receiving the second verification code and the user ID, the access control module also turns on the camera to record a video or take a photo of the user; and, after step S4, step S5 is also executed to close the access lock, turn off the camera, stop the video recording or photo taking, and store the video recording or photos that have been taken.

[0010] Applied to the above-mentioned technical solutions, in the access lock control method: before step S1, step S0 is also executed: the user ID of the mobile communication terminal user and the access ID of the access lock are set through the background server; the two are associated with each other and stored in the background server and the access control module respectively.

[0011] Applied to the above-mentioned technical solutions, in the access lock control method: in step S0, identity authentication information and permissions are also set for the mobile communication terminal user through the background server; and the encryption algorithm for generating the first verification code by the DSP processor is authorized to the mobile communication terminal user, and when the mobile communication terminal sends the second verification code and the user ID, the identity information of the mobile communication terminal user is also sent to the background server.

[0012] Applied to each of the above-mentioned technical solutions, an access lock management system used in any one of the access lock control methods based on two-way interaction of sound wave / voice communication includes a mobile communication terminal, an access control module installed on the door and connected to the access lock, and a background server, wherein the mobile communication terminal is communicatively connected to the background server; the access control module includes a DSP processor, and a loudspeaker, a pickup, a memory, a power supply module and a switch device respectively connected to the DSP processor; wherein the switch device is connected to the access lock; and the memory is connected to the DSP processor pin in an IIC manner.

[0018] 2. The present invention interacts through sound waves or voice, and adopts an access control system that does not require networking to achieve the networking function.

[0019] 3. Since the first verification code is randomly generated by the DSP processor through an encryption algorithm, the second verification code is the same as the first verification code or is generated based on the first verification code, so that the verification code is not easily copied by other devices, making the access control system more secure.

[0020] 4. During the verification process, a video or photo is taken by a camera device, and the mobile communication terminal user also sends his identity information to the backend server so that the backend server knows the actual situation of the door opening, which also increases security issues;

Accurately collect, transmit and process the dynamic information of the floating population in and out of the housing and the access lock. The tenant housing has a very high safety factor, is easy to use, low cost, and is not affected by the network or other external environment; it improves the convenience and safety of the floating population housing.

[0027] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] The present embodiment provides a method and system for access lock control based on two-way interaction of sound wave / voice communication: the method and system include a mobile communication terminal, an access control module, a background server, a camera device, and an access lock.

[0029] Among them, the mobile communication terminal is a communication device such as a mobile phone, IPad, smart wearable, etc., and a program software that interacts with the access control module is installed on the mobile communication terminal; the program software can be an APP or a small program, for example, it can be a WeChat small program or an Alipay small program; it can be realized through existing software technology; the mobile communication terminal is connected to the backend server for communication, and the tenant uses his own mobile communication terminal to register on the program software with valid documents, face recognition, voiceprint recognition, mobile phone number and other information on the software program to become a mobile communication terminal user. The mobile communication terminal user can use the application of relevant permissions. After successful registration, he can log in to the system to select the access control lock permission request for the rented house. After the tenant (landlord) is authorized on the backend server, the backend server authorizes the access control ID of the house authorized by the tenant to the mobile communication terminal user through an encryption algorithm.

[0030] Furthermore, the voiceprint information of the mobile communication terminal user can also be entered into the access control module and stored in the memory. When sending the second verification code and user ID, the mobile communication terminal user can choose to send it through sound waves or voice, and can choose the best method according to different application scenarios.

[0031] like Figure 1 As shown, the access control module of the present invention is installed on the door, and is connected to the access lock through a switch device, wherein the access control module is provided with a loudspeaker, a pickup, a DSP processor, a memory, a power supply module, and a switch device, wherein the switch device is a switch tube / relay assembly.

[0032] like Figure 2 As shown, the DSP processor adopts an LQFP-48 package chip or an SSOP-28 package chip, and the pickup is set to a microphone MK1, which is connected to the chip pin of the DSP processor and is connected to the second amplifier circuit inside the DSP processor through the chip pin; the microphone MK1 collects the sound waves or voice sent by the mobile communication terminal user through the mobile communication terminal, and verifies it after passing through the second amplifier circuit inside the DSP processor; wherein, the sound wave is sent through the mobile communication terminal, and the voice can be sent through the mobile communication terminal, and can also be sent through the voice of the mobile communication terminal user.

[0033] The loudspeaker is set as a speaker LS1, which is connected to the chip pin of the DSP processor and is connected to the first amplifier output pin inside the DSP processor through the chip pin. The first verification code and the access control ID are amplified by the first amplifier and then emitted through the loudspeaker; wherein, the loudspeaker emits sound waves.

[0034] like Figure 3As shown, the memory U2 is connected to the DSP processor pin IIC mode, and the memory U2 is used to store the first verification code randomly generated by the DSP processor through the encryption algorithm, as well as the access control ID, the second verification code and the user ID, wherein the first verification code is randomly generated and stored at any time, the access control ID is a fixed access control ID corresponding to the access control lock, and the second verification code is the same as the first verification code or is calculated and generated based on the first verification code, and its generation method is consistent with the rules and methods generated by the mobile communication terminal user. In addition, the memory U2 can also store the voiceprint of the person collected in advance, store the voiceprint in the memory and the background server, and use it as the user ID.

[0035] like Figure 4 As shown, the switch device K1 is connected to the DSP processor pin SPI communication mode, the access lock is linked to the switch device K1 of the access control module, the access lock is driven to open according to the unlocking instruction of the access control module, and the switch device K1 is linked to the mechanical brake main component of the access lock; wherein the mechanical brake main component of the access lock is K2, and the switch device K1 drives the unlocking action of the mechanical brake main component K2 of the access lock according to the unlocking instruction sent by the DSP processor; wherein the switch device K1 is a switch tube or a relay component.

[0036] like Figure 5 As shown, the camera device is generally a camera, and the camera has two functions: online and offline. After receiving the second verification code and the user ID, the access control module also turns on the camera device to record video or take photos of the user; and, when the access lock is closed, the camera device is turned off to stop the video recording or photo taking, and the video recording or photos that have been taken are stored.

[0037] Furthermore, when the tenant registers as a mobile communication terminal user, identity authentication information and permissions are set for the mobile communication terminal user through the background server; when the mobile communication terminal user sends the second verification code and the user ID, the mobile communication terminal user also sends his identity information to the background server.

[0038] The unlocking process of this embodiment is as follows:

[0039] First, the user ID of the mobile communication terminal user and the access control ID of the access control lock are set through the background server; the two are associated with each other and stored in the background server and the access control module respectively; and the encryption algorithm for generating the first verification code by the DSP processor is authorized to the mobile communication terminal user; so that after the mobile communication terminal logs in to the mobile communication terminal user through the program software, the encryption algorithm authorized by the background server can receive the first verification code and access control ID from the access control module.

[0040] Among them, the access control module is installed on the door and connected to the access control lock, and, in the access control module, the DSP processor randomly generates a first verification code through an encryption algorithm. After processing, the DSP processor sends the first verification code and the access control ID of the access control module through a loudspeaker connected to it through sound waves; wherein the DSP processor can randomly send the first verification code and access control ID to the outside.

[0041] Then, when the mobile communication terminal user approaches the access control lock, it receives the first verification code and the access control ID. When verifying that the user ID of the mobile communication terminal user is associated with the access control ID, the mobile communication terminal user generates a second verification code based on the first verification code, and sends the second verification code and user ID through sound waves or voice.

[0042] The access control module receives the second verification code and the user ID through the microphone; after amplification by the amplifier, it verifies whether they are consistent with the first verification code and the access control ID stored therein, if yes, the verification is passed; if not, the verification fails, and the unlocking is restarted;

[0043] After successful verification, the access control module issues an unlocking command and opens the corresponding access lock through the switch device.

[0044] Among them, since the access control ID of each access control module is unique, and each mobile communication terminal user ID is also unique, the access control ID and user ID can be modified through the background server; in this way, the householder can modify it according to the flow of tenants to ensure timely update of the user ID.

[0045] If the access control module fails to verify, the mobile communication terminal user can feedback an error message and send the identity information of the mobile communication terminal user to the backend server. And an error prompt message will be made on the access control lock, such as a text message prompt, voice prompt, indicator light prompt, etc. If the verification and unlocking fails multiple times, the mobile communication terminal user will directly send a warning notification to the backend server.

[0046] After receiving the second verification code and the user ID, the access control module also turns on the camera to record or take photos of the user; and when the access lock is closed, the camera stops recording or taking photos, and the recorded videos or photos are stored. In this way, the dynamic information of the identity who operates the access lock can be recorded or photographed by the camera to record and track; at the same time, the dynamic operation information can also be generated by the mobile communication terminal user; the dynamic information of the door lock includes: the time and place of unlocking, the on-site picture or video certificate of the unlocking person's registration identity; when the door lock is closed, the camera is stopped, and the collected information is uploaded to the background server or saved to the camera locally, and the mobile communication terminal sends it to the background server synchronously. It is convenient for supervision to prevent other abnormal intentional disturbances such as improper operation of the unauthorized elements.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
