In this embodiment, when the server determines that the smart door lock is prohibited from being opened, the server sends a control instruction prohibiting the opening of the smart door lock to the smart door lock; For door locks, the server sends a visitor prompt message to a designated terminal.

In order to facilitate the understanding of the embodiments of the present invention, an embodiment of a specific application will be provided below for detailed description.

In this embodiment, the smart door lock has a voice collection module, a power supply module, a door lock opening and closing control module, a lockset module and a communication module. The power module is used to provide power supply for each module. The door lock opening and closing control module communicates with the server of the Internet of Things operating system through the communication module. The voice collection module can collect the voice of the user using the door lock and upload it through the communication module. to the server of the IoT operating system. The lock module can be a mechanical lock structure in the prior art.

In this embodiment, an unlocking control method based on the Internet of Things operating system is provided. In this embodiment, the voice of the user at the door is collected by the voice collection device (for example, a microphone) arranged on the smart door lock, and then the collected voice file is transmitted to the Internet of Things through the communication module (Bluetooth, WIFI, etc.) operating system server. The server performs keyword recognition on the speech, and when it recognizes that the speech includes the specified keyword, the server obtains whether the mobile terminal of the home user has operation data related to the keyword, and finally based on the relevant operation data in the cloud server in real time The operating state realizes the control of opening the door lock.

The process flow of the door lock control method provided in this embodiment is shown in Figure 4, and mainly includes the following steps:

Step S401, the voice collection module of the smart door lock collects the voice within the specified range in front of the safe door, generates an audio file and transmits it to the server of the Internet of Things operating system through the communication module;

Existing smart door locks all have a doorbell function, and when there is a visitor in the family, it can prompt the family member user to turn on the smart door lock switch by pressing the doorbell.

In this embodiment, the voice collection function of the voice collection module can be turned on after the smart door lock receives the input signal that the visitor presses the doorbell. Specifically, after the visitor presses the doorbell, the door lock opening and closing control module of the smart door lock will be triggered to generate a doorbell prompt command and a voice collection command, which are sent to the doorbell and voice collection module respectively, and then the doorbell prompt and voice collection will be performed.

In this embodiment, the specified range in front of the security door can be controlled by adjusting the sound collection range of the microphone, and the sound collection range of the microphone can be adjusted by adjusting the sensitivity of the microphone.

In step S402, the server of the Internet of Things operating system identifies whether there is a preset keyword in the voice data, if yes, execute step S403, if not, end the process, and execute step S408.

In the Internet of Things operating system, users can pre-configure and set keywords for speech recognition and judgment. For example, "express delivery", "takeaway", "meal delivery", "send" and other content can be set as keywords.

Specifically, voice recognition technology may be used to identify the content of the audio file collected by the microphone, and determine whether the audio file includes keywords set by the user. Currently commonly used speech recognition methods include: methods based on vocal tract models and speech knowledge, template matching methods, and methods using artificial neural networks. Specifically, a relevant speech recognition method may be selected according to application requirements.

For example, after the visitor presses the doorbell, he will ask "Hello, is there anyone at home? Is there your courier...", and then the microphone on the smart door lock will collect the visitor's speech, perform analog-to-digital conversion, and generate an audio file. Send to the server of the Internet of Things operating system, the server uses speech recognition technology to identify and judge the audio file, and recognize whether the set keyword is included in the audio file. It can be determined that the above audio file includes the keyword "express" , the following system will perform the operation of step 3.

For another example, after the visitor presses the doorbell, he asks "Hi, is there anyone at home?" The microphone collects the voice and uploads it to the server of the IoT operating system. ", "takeaway", "meal delivery", "send" and other keywords, therefore, the server of the IoT operating system will not perform any operations.

In this solution, the microphone can be set on the smart door lock or at other locations, as long as the collection of visitor voice data can be realized. At the same time, it can be set to turn off the recording of the microphone when there is no sound source input from the microphone for more than 5 minutes. After the doorbell is pressed next time, it will automatically trigger and start sound collection.

Step S403, according to the matched keyword, it is judged whether the order information corresponding to the keyword exists in the mobile terminal, if yes, execute step S404, if not, execute step S408.

Multiple keywords can be set in the system, and each keyword will have one or more mobile terminal applications (APPs) corresponding to it. For example, the mobile terminal application corresponding to the keyword "express delivery" can include "Tmall", "Taobao", "Jingdong", etc., and the keywords "takeaway" and "meal delivery" can correspond to the same mobile terminal applications, such as "Meituan", "Eleme", "Alipay", "WeChat", etc. In order to facilitate the configuration of keywords and applications, when users initially set keywords in the IoT operating system, they can simultaneously configure the mobile terminal applications corresponding to keywords to form a correspondence table between keywords and mobile terminal applications.

According to the above content, the order information corresponding to the keyword actually refers to the purchase/consumption order information in the mobile terminal application corresponding to the keyword. In this solution, the order information does not include the order status as "Completed" orders.

For example, in an example, by executing step S402, it can be determined that the keyword matched in the visitor's voice is "express delivery", then, in step S403, the server of the Internet of Things operating system will firstly collect all the mobile phone terminals in the family according to the (1, 2, 3, ...) The uploaded terminal data obtains the application information downloaded by all mobile terminals in the family, and then determines whether there is an application related to the keyword "express delivery" determined in step S402 according to these application information , For example, whether to download applications (APPs) such as "Jingdong" and "Tmall" on the mobile terminal. From the above judgments, it can be seen that the mobile terminal 1 in the family has the "Jingdong" APP related to the keyword "express" installed, and the mobile terminal 2 has the "Tmall" and "Taobao" APPs related to the keyword "express". .

The server of the Internet of Things operating system will obtain all unfinished order information in the "Jingdong" APP in the mobile terminal 1 from the corresponding server of the "Jingdong" APP in the mobile terminal 1 through the wireless network, and obtain the order information from the mobile phone terminal 1. The corresponding servers of the "Tmall" APP and "Taobao" APP in the terminal 2 obtain all unfinished order information in the "Tmall" APP and "Taobao" APP in the mobile terminal 2.

Of course, before the server of the Internet of Things operating system obtains the order information of the above APPs, it can establish a cooperative relationship with the companies of these APPs in advance to obtain the data authorization of the servers corresponding to these APPs, which can be official authorization. On the other hand, before the server of the Internet of Things operating system obtains the order information of the above APP, it can also ask the user whether to authorize it to obtain the order information by pushing an authorization inquiry page. If the user agrees to authorize, the Internet of Things operating system The server obtains user authorization.

On the premise that the server of the Internet of Things operating system is authorized by both the official and the user, the server can obtain relevant information from the servers of related applications in all mobile terminals in the home through the wireless network.

In another example, by executing step S402, it can be determined that the keyword matched in the visitor's voice is "order food", then, in step S403, the server of the Internet of Things operating system will obtain the information in the home through the wireless network. All the application information in the mobile terminal determines whether there is an application related to the keyword "ordering food" in the mobile terminal, that is, whether the application (APP) such as "Meituan Waimai" and "Eleme" is downloaded on the mobile terminal, through It can be seen from the judgment that the above application programs are not installed in all mobile terminals in the family. At this time, the server of the Internet of Things operating system cannot obtain the order information, and the server will directly execute step S408 to directly end the process. At this time, the smart door lock does not open and remains in the current closed state. A prompt instruction can also be generated and sent to a designated mobile terminal to prompt the mobile terminal user.

For the application program in the mobile terminal, it will obtain the order information in the application program from the network server in real time through the mobile communication network/WIFI network, such as the real-time status data of the order.

Step S404, acquiring order status data of the order information, the order status data including order location data and delivery status data.

In the above step S403, the server of the Internet of Things operating system obtains order status data from the received order information, and the order status data mainly includes delivery status data and real-time location data of the order.

Usually, after the user consumes or orders food in the application program in the mobile terminal, an order information will be generated immediately, which records the status of the current order, such as payment status (unpaid, completed payment), delivery status (not yet Delivery, delivery, transportation, etc.), location status (the current location of the product, the real-time displacement of the delivery person).

In step S405, the server of the Internet of Things operating system judges whether the order status in the delivery status data is in delivery, if yes, execute step S406, and if no, execute step S408.

Step S406, continue to judge whether the location of the delivery person in the location data has arrived at the delivery address (that is, the location of the smart door lock), if not, go to step S407; if yes, go to step S408.

Judging whether the order status of the delivery status data is "delivering" can determine whether there are currently express orders to be received. If there are express orders to be received, it is necessary to continue to determine whether the current delivery location of the delivery person in the location data is already arrived The receiving address (that is, the positions of the two coincide). If the positions coincide, it can be determined that the express order has arrived at the destination (the current visitor's identity is correct). If the positions do not coincide, it can be determined that the express order has not arrived. No need for users Receive express delivery. At this time, the system will determine that the current visitor's identity is incorrect and there will be a potential safety hazard, and thus the operation of step S408 will be performed.

Step S407, the server of the Internet of Things operating system sends a control command prohibiting opening the door lock to the door lock opening and closing control module of the smart door lock through the home gateway, so as to control the lock structure from being opened.

Through the judgment of the order status in the above steps S405 and S406, the identity of the current visitor can be confirmed. If it is confirmed as unsafe, the server of the Internet of Things operating system will generate an instruction forbidding to open the door lock and send it to The door lock opening and closing control module of the smart door lock. After receiving the instruction, the door lock opening and closing control module will generate a driving instruction for closing the door lock and send it to the lock structure for execution.

Step S408, end the process or generate a visitor reminder command, and send it to a designated mobile terminal (manager's mobile terminal) to remind the mobile terminal user.

When the server of the IoT operating system determines that the identity of the current visitor is safe, the user will not be prohibited from opening the door lock. At the same time, in order to facilitate monitoring and management, visitor prompt instructions can be generated and sent to the mobile terminals of family members. For example, when a child is at home alone, when there is a visitor, and the visitor is judged to be safe, the system will send a reminder message to the mobile phone of the child's parents (for example, mother), so that the parents can Supervision and care can be carried out according to the prompts.

In the above-mentioned embodiment, the key words in the visitor's voice are captured by voice recognition, and different application programs of the mobile terminal are matched according to the key words, and then the order information in the unfinished state in the application program is called, and then according to The order status data and delivery location data included in the order information determine whether the visitor's identity is accurate, thereby realizing the control of the opening of the smart door lock. Ensure the personal and property safety of home users, and avoid other people who falsely report as courier delivery and meal delivery personnel from entering the home.
