It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0028] Figure 2 is a flowchart of the method for controlling the door lock to open according to the embodiments of the present application. As shown in Figure 2 the method includes the following steps:

[0029] Step S201, a user data repository is constructed, the user data repository storing at least one of a reference step number and a reference frequency, and a predicted time of the user to the door, the reference step number being a step number of the user from an elevator door or a stair door to the door in a historical time, the reference frequency being a walking frequency of the user in the historical time;

[0030] Specifically, the user data repository is a MySQL database, an Oracle database, a SqlServer database, and other databases.

[0031] For example, the predicted time of the user to the door is: expected to arrive after 15 minutes, expected to arrive after 10 minutes, expected to arrive after 8 minutes.

[0032] For example, the historical time is within the previous month, within the previous half month.

[0033] For example, the reference step number corresponding to the A user is 10 steps, the reference step number corresponding to the B user is 15 steps, the reference step number corresponding to the C user is 13 steps, the walking frequency corresponding to the A user is 60 steps / minute, the walking frequency corresponding to the B user is 70 steps / minute, and the walking frequency corresponding to the C user is 80 steps / minute.

[0034] The data obtained by this data repository needs to be initialized by the user for the first time, that is, the user needs to actually operate once to give the step number, the frequency, and the corresponding time to the record data repository in the central control subsystem for initialization data.

[0035] Step S202, at least one of an actual step number and an actual frequency, and an actual time of the user to the door are obtained, the actual step number being a step number of the user from an elevator door or a stair door to the door in the current time, the actual frequency being a walking frequency of the user to the door in the current time.

[0036] Specifically, the actual time can be understood as follows: when the user comes out from the elevator or the stair door, the sound recognition module on the door lock collects the first walking sound as the start time, and the infrared sensing module on the door lock is triggered for the first time as the end time, and the actual time of the user from the elevator door or the stair door to the door is from the start time to the end time; the actual step number is collected by the sound recognition module.

[0037] Step S203, in the case that at least one of a first condition and a second condition is met, and a third condition, the third condition being that a difference between the predicted time and the actual time is less than a preset time difference, the first condition being that a difference between the reference step number and the actual step number is less than a preset step difference, and the second condition being that a difference between the reference frequency and the actual frequency is less than a preset difference, the door lock is controlled to be opened.

[0038] Specifically, the preset time length difference value is set to 3 minutes; of course, in actual application, the preset time length difference value can be adjusted according to actual needs;

[0039] Specifically, the preset step difference value can be set to 1 step, and the preset difference value can be set to 5 steps / minute.

[0040] The third condition is satisfied, which means that the predicted time and the actual time are equal or very close, the second condition is satisfied, which means that the reference frequency and the actual frequency are equal or very close, and the first condition is satisfied, which means that the reference step number and the actual step number are equal or very close.

[0041] Specifically, the first condition and the second condition satisfy at least one of them and the third condition is satisfied, and the door lock is controlled to be opened, including three modes: 1) the first condition and the third condition are satisfied; 2) the second condition and the third condition are satisfied; 3) the first condition, the second condition and the third condition are satisfied.

[0042] In this embodiment, by constructing a user data repository, at least one of a reference step number and a reference frequency and a predicted time of a user to a door are stored in the user data repository, the reference step number is a step number of the user walking from an elevator port or a stair port to the door in a historical time, and the reference frequency is a walking frequency of the user in the historical time; at least one of an actual step number and an actual frequency and an actual time of the user to the door are obtained, the actual step number is a step number of the user walking from the elevator port or the stair port to the door in a current time, and the actual frequency is a walking frequency of the user walking to the door in the current time; in a case where at least one of a first condition and a second condition and a third condition are satisfied, the door lock is controlled to be opened, the third condition is that a difference value between the predicted time and the actual time is less than a preset time length difference value, the first condition is that a difference value between the reference step number and the actual step number is less than a preset step difference value, and the second condition is that a difference between the reference frequency and the actual frequency is less than a preset difference. According to at least one of the difference value between the reference step number and the actual step number, the difference between the reference frequency and the actual frequency, and the difference value between the predicted time and the actual time, whether the door lock is opened or not can be controlled, and the door lock can be opened without the user operating the door lock.

[0043] In the embodiment of the present application, the predicted time of the user to the door is input by the user into a terminal application through a preset input mode, the terminal remotely communicates with the door lock, and the method further comprises:

[0044] Real-time position information of the user is obtained; according to the real-time position information and position information of the destination, a calculated time of the user to the door is obtained; in a case where a difference value between the predicted time of the user to the door and the calculated time of the user to the door is less than or equal to a difference value threshold, it is determined that the user can arrive at the door in the predicted time; in a case where the difference value between the predicted time of the user to the door and the calculated time of the user to the door is greater than the difference value threshold, it is determined that the user cannot arrive at the door in the predicted time.

[0045] The preset input mode can be set by the app door lock plug-in page, and the personalized home time can be input by text or voice;

[0046] The real-time location information is obtained through the mobile phone app;

[0047] The difference threshold value can be set to 1 minute, 3 minutes, or 5 minutes;

[0048] According to the real-time location information and the location information of the destination, the calculation time of the user to the door is obtained, and the specific implementation is as follows:

[0049] According to the real-time location information and the location information of the destination, the distance is obtained, for example, 5 kilometers;

[0050] According to the distance from the user to the destination, the transportation tool is selected, for example, taking a bus, driving a car, walking, or other transportation tools, and the calculation time of the user to the door is obtained.

[0051] For example, the user sets a home time in the plug-in page, or inputs a voice command "I expect to be home in 10 minutes" through voice input, and at the same time, the actual location of the user is obtained to estimate whether the user can arrive home at the set time, and a verification comparison is made; in this way, a difference threshold value can be set to compare the difference between the predicted time of the user to the door and the calculation time, which can be used to determine whether the user can arrive at the door at the predicted time, so that the scheme is more reasonable.

[0052] Further, after determining that the user cannot arrive at the door at the predicted time, the method further comprises: after determining that the user cannot arrive at the door at the predicted time, correcting the predicted time of the user to the door by using the difference between the predicted time of the user to the door and the calculation time of the user to the door, to obtain the corrected predicted time of the user to the door.

[0053] The method is used when the user cannot arrive at the door within the predicted time, and the predicted time is corrected according to the difference between the actual calculation time and the predicted time; when the calculation time is greater than the predicted time, the difference threshold value is increased; when the calculation time is less than the predicted time, the difference threshold value is reduced;

[0054] For example, the predicted time is 10 minutes, the calculation time is 15 minutes, the difference threshold value is 3 minutes, the calculation time is greater than the budget time, the difference is 5 minutes which is greater than the difference threshold value, and the predicted time is corrected to 15 minutes.

[0055] In this way, the prediction time system can be continuously improved, and the automatic door opening effect can be achieved more flexibly and intelligently.

[0056] Further, the user data repository stores a plurality of different reference frequencies, each corresponding to a shoe type. In the case that the first condition and the second condition and the third condition are met, before the door lock is controlled to open, the method further comprises: comparing the plurality of reference frequencies with the actual frequency one by one to obtain a comparison result; in the case that the comparison result represents that the difference between the actual frequency and any one of the plurality of reference frequencies is less than a preset difference, it is determined that the second condition is met; in the case that the comparison result represents that the difference between the actual frequency and all reference frequencies is greater than or equal to the preset difference, it is determined that the second condition is not met.

[0057] For example, the shoe types include cloth shoes, sports shoes and leather shoes, the reference frequency corresponding to the cloth shoes is the first reference frequency, the reference frequency corresponding to the sports shoes is the second reference frequency, and the reference frequency corresponding to the leather shoes is the third reference frequency.

[0058] In the case that the actual frequency is consistent with the first reference frequency or the difference is small, or is consistent with the second reference frequency or the difference is small, or is consistent with the third reference frequency or the difference is small, it is determined that the second condition is met.

[0059] The method has the difference between the tone corresponding to any one of the reference frequencies in the user data repository and the tone corresponding to the actual frequency less than or equal to a preset difference, realizes automatic opening of the door lock, and can achieve more accurate judgment and automatic unlocking convenience.

[0060] Before the user data repository is constructed, the method further comprises: obtaining sound data when a user walks in different types of shoes; and extracting a plurality of reference frequencies from the plurality of sound data.

[0061] The method obtains data of the user walking in different types of shoes, collects sound according to the sound frequency and tone caused by the weight of the user, the sole material of the shoes and the contact area with the ground, and performs difference comparison between the reference sound data and the actual sound data. If the condition is met, the actual sound data is recorded into the system as one of the reference data for subsequent difference comparison. In this way, the door lock can be automatically opened, the use is more flexible, and the safety is greatly improved.

[0062] In the embodiment, the actual step count obtained in the step S202 includes: obtaining the distance between the elevator entrance or the staircase entrance and the door entrance; obtaining the actual time taken by the user to walk from the elevator entrance or the staircase entrance to the door entrance; and determining the actual step count according to the distance and the actual time.

[0063] The mapping relationship among the distance, the time and the step count in the historical time period is determined, that is, the mapping relationship between the distance and the time and the step count is constructed.

[0064] According to the mapping relationship, the actual distance from the elevator or stairway entrance to the door and the actual time from the elevator or stairway entrance to the door are derived to obtain the actual number of steps;

[0065] Based on the mapping relationship, for example: 1) the distance is 8 meters, the time is 5 seconds, and the actual number of steps is 10 steps; 2) the distance is 8 meters, the time is 6 seconds, and the actual number of steps is 12 steps;

[0066] In this way, the first condition for automatically opening the door lock can be more accurate and flexible.

[0067] Further, the method further comprises: in the case that at least the third condition is not met, controlling the door lock to remain in a closed state.

[0068] The third condition of the method is a necessary condition for automatically opening the door lock in the present solution embodiment, which can improve the accuracy of automatic unlocking and avoid the problem of automatic door unlocking failure due to inaccurate first and second conditions.

[0069] Further, the user data repository also stores reference user image data, and the method further comprises: acquiring real-time user image data collected in real time; and in the case that the third condition and the fourth condition are met, controlling the door lock to open, wherein the fourth condition is that the similarity between the real-time user image data and the reference user image data is greater than a preset similarity.

[0070] The method uses the user image data stored in the data repository for identification, compares the actual user image with the reference user image, and controls the door lock to automatically open if the similarity is greater than a preset similarity and any one of the first condition and the second condition and the third condition is met. The fourth condition is added, which can greatly improve the accuracy and safety of automatically opening the door lock.

[0071] In order for those skilled in the art to more clearly understand the technical solutions of the present application, the implementation process of the method for controlling the door lock to open will be described in detail below in conjunction with specific embodiments.

[0072] The present embodiment relates to a specific method for controlling the door lock to open, as shown in Figure 4 The method comprises the following steps:

[0073] Step S1: comparing the total distance from the elevator or stairway entrance to the door and the time taken to walk from the elevator or stairway to the door to derive the number of steps generated during the period as the first condition;

[0074] Step S2: inputting the frequency of each type of user shoes as the second condition;

[0075] Step S3: inputting the personalized home time of the user as the third condition;

[0076] Step S4: comparing the first condition, the second condition, the third condition with the user feature and the dynamic library of the personalized record;

[0077] Step S5: confirming the user identity when the first condition, the third condition are met or the second condition, the third condition are met or the first condition, the second condition, the third condition are met, and the door lock is opened by the control.
