[0049] The following will clearly and completely describe the concept of the invention and the resulting technical effects in combination with the embodiments, so as to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts all fall within the scope of protection of the present invention.

If it involves "first" and "second", it should be understood as used to distinguish technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0051] Referring to Figure 1 , the embodiments of the present invention provide a XingShan perception access control method, which includes the steps:

[0052] S100. Monitor in real time to receive the XingShan wireless unlocking signal sent by the XingShan digital key within a preset range;

[0053] Among them, the XingShan perception access control controller monitors in real time whether there is a XingShan wireless unlocking signal sent by the XingShan digital key within the preset range. By setting a preset range area, not only can it avoid the excessive power consumption of the XingShan perception access control controller and the XingShan digital key caused by continuously being in the signal receiving state or signal sending state, but also it can effectively avoid the possibility of the access control device being mistakenly triggered to perform the door opening action when the user carries the XingShan digital key outside the preset range. In practical applications, the area of the preset range can be set according to specific application scenarios to meet different user needs.

[0054] S200. Judge the legality of the XingShan wireless unlocking signal;

[0055] Among them, since the XingShan perception access control controller may monitor unauthorized XingShan wireless unlocking signals within the preset range area, in order to reduce the workload of the XingShan perception access control controller and its power consumption, the legality of the XingShan wireless unlocking signal sent by the XingShan digital key is judged before processing it. The legal XingShan wireless unlocking signals are further processed, and the illegal XingShan wireless unlocking signals are ignored and skipped, thereby improving the working efficiency of the XingShan perception access control controller.

[0056] If it is judged in step S200 that the XingShan wireless unlocking signal is a legal signal, then execute the steps:

[0057] S300. Receive and calculate the signal strength information of the SparkLink wireless unlocking signal, and control the access control device to perform the unlocking action according to the signal strength information;

[0058] Among them, after it is determined in step S200 that the received SparkLink wireless unlocking signal is a legal signal, in order to improve the accuracy of the SparkLink-aware access control controller to perform the unlocking action, the SparkLink wireless unlocking signal is further processed. By calculating the signal strength information of the SparkLink wireless unlocking signal, and then when the obtained signal strength information meets the preset unlocking condition, the SparkLink-aware access control controller controls the access control device to perform the unlocking action; and when the signal strength information does not meet the preset unlocking condition, the SparkLink-aware access control controller controls the access control device to maintain the current state (locked state).

[0059] If it is determined in step S200 that the SparkLink wireless unlocking signal is an illegal signal, then execute the steps:

[0060] S400. Return to execute step S100 to monitor in real time to receive the SparkLink wireless unlocking signal sent by the SparkLink digital key within the preset range.

[0061] In an embodiment of the present invention, a SparkLink-aware access control method, by monitoring and receiving in real time the SparkLink wireless unlocking signal sent by the SparkLink digital key within the preset range, and after determining that the received SparkLink wireless unlocking signal is a legal signal, receiving and calculating the signal strength information of the SparkLink wireless unlocking signal, and further controlling the access control device to perform the unlocking action according to the signal strength information; thus solving the technical problems of poor control accuracy, high power consumption and poor security existing when the access control device in the related art adopts Bluetooth wireless transmission technology, NFC wireless transmission technology or RFID wireless transmission technology.

[0062] Refer to Figure 2 , in some embodiments, in order to be able to accurately control the unlocking / locking state of the access control device according to the signal strength information of the SparkLink wireless unlocking signal, and avoid mis-triggering or being unable to trigger the access control device to unlock, in this embodiment, step S300 described in the above embodiment includes sub-steps:

[0063] S310. Calculate multiple data points in sequence to obtain multiple signal strength information;

[0064] Among them, within the area of the preset range, the SparkLink digital key continuously sends SparkLink wireless unlocking signals to the SparkLink sensing access control controller. To avoid the problem of inaccurate unlocking caused by the user carrying the SparkLink digital key accidentally triggering the unlocking action of the access control device when passing through briefly or staying at the edge area of the preset range for a short time within the preset range area, during the process of the SparkLink digital key sending SparkLink wireless unlocking signals to the SparkLink sensing access control controller, multiple signal strength information is obtained by sequentially calculating multiple data points, and then precise control of the access control device is achieved through data analysis of the multiple signal strength information.

[0065] S320. Sequentially assign weights to multiple signal strength information in a linearly increasing manner to obtain a signal strength curve composed of multiple signal reference strength values.

[0066] Among them, sequentially assigning weights to multiple signal strength information in a linearly increasing manner means that the weight of the previously obtained signal strength information is less than the weight of the subsequently obtained signal strength information. For example, r1, r2, r3, r4, and r5 respectively represent the signal strength information obtained in sequence, then the sequential weight coefficient assignments are 1, 2, 3, 4, and 5, and the multiple signal reference strength values are respectively represented as 1r1, 2r2, 3r3, 4r4, 5r5; the signal strength curve composed of multiple signal reference strength values can achieve dynamic evaluation of the signal strength information.

[0067] S330. On the signal strength curve, starting from each signal strength reference value, continuously calculate multiple unlocking values within the preset window length in sequence. If the current unlocking value is greater than or equal to the preset unlocking threshold, control the access control device to unlock.

[0068] Among them, the preset window length represents the number of signal strength reference values for parameter calculation. By introducing multiple signal strength reference values for calculating the unlocking value, it can avoid the problem of poor unlocking accuracy when the SparkLink sensing access control controller controls the access control device to perform the unlocking action only based on a single strength reference value when the user carries the SparkLink digital key and is briefly within the preset range. In some specific embodiments, the preset window length is set to 5, that is, 5 signal strength reference values are used to calculate the unlocking value. When calculating the unlocking value, when the obtained current unlocking value is greater than or equal to the preset unlocking threshold, control the access control device to perform the unlocking action, thereby avoiding the problem of poor unlocking accuracy. In specific applications, the preset unlocking threshold can be set according to the actual application scenario to meet the actual needs.

[0069] S340. If all the multiple unlocking values obtained in the above steps are less than the preset unlocking threshold, control the access control device to be in a locked state.

[0070] Among them, if multiple obtained unlocking values continuously calculated by the SparkLink-aware access control controller are all less than a preset unlocking threshold, it indicates that the user carrying the SparkLink digital key is not approaching the access control device, and then the access control device is controlled to be in a locked state, avoiding the possibility of accidentally triggering the unlocking of the access control device.

[0071] Referring to Figure 3 , in some embodiments, to improve the accuracy of calculating the current unlocking value in the above embodiments, after obtaining the signal strength curve composed of multiple signal reference strength values in step S320, the following steps are further included:

[0072] S321. Perform noise reduction processing on the signal strength curve;

[0073] In this embodiment, the noise reduction processing is to input the data information of the signal strength curve into a Kalman filter to denoise the noise in the data information, thereby improving the accuracy of the data information of the signal strength curve, providing the accuracy for subsequent calculation of the unlocking value, and finally realizing the precise control of the on / off state of the access control device.

[0074] Referring to Figure 4 , in some embodiments, to ensure the realization of the precise unlocking function and prevent the situation that due to the too long processing time of the SparkLink wireless unlocking signal sent by a single SparkLink digital key, when the user may be outside the preset range area and then enters the preset range again, the SparkLink-aware access control controller may accidentally trigger the control of the access control device to perform the unlocking action immediately. Step S300 in the above embodiments further includes the following steps:

[0075] S350. If no new signal strength information is obtained within a preset time interval and the number of currently obtained signal strength information is lower than the value of the preset window length, terminate the current unlocking process.

[0076] Among them, when the number information of the obtained signal strength information (i.e., the corresponding signal strength reference value) is lower than the value of the preset window length and no new signal strength information is obtained within the preset time interval, it indicates that the SparkLink digital key carried by the user has been outside the preset range area, and then the current unlocking process is terminated, which can effectively improve the response efficiency and security of controlling the access control device. In some embodiments, the preset time interval can be set to 2 seconds, but the specific value of this preset time interval can be set according to the specific application scenario.

[0077] In some embodiments, after obtaining multiple signal reference intensity values and setting a specific preset window length in the above embodiments, an unlocking value can be calculated based on the obtained multiple signal reference intensity values and the value of the preset window length. By using a sliding window method to calculate the continuously obtained multiple signal reference intensity values, multiple unlocking values are correspondingly obtained. In this embodiment, after obtaining a signal intensity curve composed of multiple signal intensity reference values by linearly increasing the weight of the multiple signal intensity information in the above embodiments, it shows the dynamic change of the intensity of the XingShan wireless unlocking signal. Accordingly, when calculating the unlocking value, its size is related to three values: the first signal intensity reference value in the preset window length, the last signal intensity reference value in the preset window length, and the value of the preset window length. In a specific embodiment, taking the preset window length of 5 as an example, the multiple signal reference intensity values are respectively represented as 1r1, 2r2, 3r3, 4r4, 5r5 in sequence. Then the specific formula for calculating the current unlocking value within the preset window length is:

[0078] k = (5r5 - 1r1) / (5 - 1) (1)

[0079] where k is the current unlocking value, which is directly proportional to the difference between the last signal intensity reference value and the first signal intensity reference value in the preset window length, and inversely proportional to the value of the preset window length; as the calculation window slides, subsequent current unlocking values are continuously calculated. When the calculated current unlocking value k is greater than or equal to the preset unlocking threshold, the XingShan sensing access controller controls the access device to perform an unlocking action and stops subsequent calculations. When no new XingShan wireless unlocking signal is received within the preset interval time (e.g., 2 seconds), the calculation of the current unlocking value is stopped.

[0080] Referring to Figure 5 , in some embodiments, in order to reduce the data processing volume of the XingShan sensing access controller, in this embodiment, after receiving the XingShan wireless unlocking signal, the XingShan sensing access controller performs data processing after judging its legality. Specifically, in this embodiment, the judgment of the legality of the XingShan wireless unlocking signal in step S200 of the above embodiment includes:

[0081] S210. Obtain the device address information corresponding to the XingShan wireless unlocking signal;

[0082] S220. Judge whether the device address is in the address whitelist;

[0083] If so, execute the steps:

[0084] S230. Judge that the XingShan wireless unlocking signal is a legal signal;

[0085] Otherwise, execute the steps:

[0086] S240. Determine that the StarFlash wireless unlocking signal is an illegal signal.

[0087] In this embodiment, when each StarFlash digital key is paired with the StarFlash sensing access control controller, the StarFlash digital key sends the address information in the pairing request information to the StarFlash sensing access control controller. Then, the StarFlash controller stores the device address information of the paired StarFlash digital key in the address white list. Further, during the use process, when the StarFlash sensing access control controller receives the StarFlash wireless unlocking signal sent by the StarFlash digital key, by determining whether the device address information in the StarFlash wireless unlocking signal is stored in the address white list, it can quickly determine whether the currently received StarFlash wireless unlocking signal is a legal signal. After determining that it is a legal signal, subsequent data processing is performed, thereby reducing the data processing volume of the StarFlash sensing access control controller and improving the data processing efficiency of the StarFlash sensing access control controller.

[0088] Refer to Figure 6 , in some embodiments, the above embodiment describes the process of unlocking with a StarFlash digital key carrying legal device address information within the preset range of the access control device; however, in some embodiments, in order to provide an unlocking service without verification for a preset direction, for example, when walking out from the inside of the door to the outside, unlocking can be performed without verification. Therefore, in this embodiment, the StarFlash sensing access control method further includes the following steps:

[0089] S500. Real-time detect whether a human presence sensing signal is received in the preset direction;

[0090] If so, execute the steps:

[0091] S600. Control the access control device to perform an unlocking action.

[0092] Among them, in a specific embodiment, the preset direction is the inside direction of the door. By setting a human presence sensor module to monitor whether there are people in the inside direction of the door, when a person is detected, a human presence sensing signal is sent to the StarFlash sensing access control controller. Then, the StarFlash sensing access control controller controls the access control device to perform an unlocking action, so that when an external visitor finishes visiting and leaves, the people inside the door can unlock and leave without carrying the paired StarFlash digital key by setting the human presence sensor.

[0093] In some embodiments, to increase the applicability of the SparkLink-aware access control method provided by the present invention and provide a good user experience for users. In this embodiment, the SparkLink-aware access control method further includes sending the switch state information of the access control device to the remote management center. In addition, the remote management center can also remotely control the switch state of the access control device. Specifically, by setting up a SparkLink gateway and / or a Xiaomi communication module to be connected to the access control, after connecting the access control controller to the Internet, it is connected to the remote management center through the Internet, so as to send the switch state of the access control device to the remote management center for real-time monitoring and recording, or to perform real-time control on the switch state of the access control through the remote management center.

[0094] In some embodiments, to enhance the user experience, when the access control device is unlocked by the SparkLink digital key or other legal means, the SparkLink-aware access control controller controls the speaker device to emit a voice prompt such as "The door has been opened, please come in" to remind the user that the access control device has been opened and provide a good user experience.

[0095] Refer to Figure 7 Accordingly, an embodiment of the present invention provides a SparkLink-aware access control controller, which includes a signal monitoring and receiving module, a signal judgment module, and an unlocking execution module. Among them, the signal monitoring and receiving module is used to monitor in real time to receive the SparkLink wireless unlocking signal sent by the SparkLink digital key within a preset range. Then, after the signal judgment module judges the legality of the received SparkLink wireless unlocking signal, when it is judged that the received SparkLink wireless unlocking signal is a legal signal, the unlocking execution module is used to calculate the signal strength information of the SparkLink wireless unlocking signal and control the access control device to perform the unlocking action according to the signal strength information. In this embodiment, by using the SparkLink wireless unlocking signal as the wireless transmission unlocking signal and using the signal strength information as the calculation basis during access control, the technical problems of poor control accuracy, high power consumption, and poor security existing in the related art when the access control device uses Bluetooth wireless transmission technology, NFC wireless transmission technology, or RFID wireless transmission technology are solved.

[0096] In some embodiments, the SparkLink-aware access control controller proposed in the embodiment of the present invention is used to implement the SparkLink-aware access control method described in any of the above embodiments, and its working process and implementation principle are mutually referred to and corresponding to the SparkLink-aware access control methods described in the above respective embodiments.

[0097] Refer to Figure 8, the embodiment of the present invention also provides a SparkLink sensing access control system, which includes an access control main device, a SparkLink digital key, and a SparkLink sensing access control controller; wherein, the SparkLink digital key is used to send a SparkLink wireless unlocking signal to the SparkLink sensing access control controller, and the SparkLink sensing access control controller is used to execute the SparkLink sensing access control method described in any of the above embodiments to process the SparkLink wireless unlocking signal to obtain an unlocking value. After comparing the unlocking value with a preset unlocking threshold, the SparkLink sensing access control controller controls the switch state of the access control main device, thereby solving the technical problems of poor control accuracy, high power consumption, and poor security in the wireless control access control system in the related art, and providing a SparkLink sensing access control system with high precision, low power consumption, and high security.

[0098] In some embodiments, the SparkLink sensing access control controller described in the above embodiments includes a first power supply module, a main control module, and a first SparkLink module. The first power supply module is used to provide working power for the main control module and the first SparkLink module; the SparkLink digital key includes a second power supply and a second SparkLink module, and the second power supply module is used to provide working power for the first SparkLink module. In this embodiment, the second SparkLink module in the SparkLink digital key is used to send out a SparkLink wireless unlocking signal, and the first SparkLink module in the SparkLink sensing access control controller is used to monitor and receive the SparkLink wireless unlocking signal and then transmit it to the main control module to process the SparkLink wireless unlocking signal to obtain an unlocking value. Furthermore, the main control module controls the unlocking state of the access control main device according to the unlocking value. In some specific embodiments, the main control module can be implemented by the ESP32-S3 system and its peripheral circuits, and both the first SparkLink module and the second SparkLink module can be implemented by the EB25 module.

[0099] Referring to Figure 9 , in some embodiments, the SparkLink sensing access control system may further include a SparkLink gateway, a Xiaomi communication module, and a remote management center; wherein, the SparkLink sensing controller can be connected to the Internet through the SparkLink gateway or the Xiaomi communication module and then connected to the remote management center. Furthermore, the SparkLink sensing controller can send the switch state of the access control main device to the remote management center through the Internet to achieve remote real-time monitoring and recording; in addition, the remote management center can also send a remote unlocking signal to the SparkLink sensing access control controller through the Internet to achieve remote unlocking.

[0100] In some embodiments, the SparkLink-aware access control system may further include a presence sensor module and a speaker; wherein the presence sensor module is configured to obtain a presence sensing signal inside the door and transmit the presence sensing signal to the SparkLink-aware access control controller. Subsequently, the SparkLink-aware access control controller sends a control signal to cause the access control main device to perform an unlocking action, thereby achieving unlocking. In this embodiment, the SparkLink-aware access control controller is further configured to send a voice broadcast signal, such as voice prompt information like "The door has been opened. Please enter", to the speaker after receiving a SparkLink wireless unlocking signal or a remote unlocking signal and controlling the access control main device to perform an unlocking action, for prompting the user that the door has been opened. In this embodiment, to accurately obtain the presence sensing signal inside the door, the presence sensor module can be implemented by a millimeter-wave radar and a third SparkLink module. After the millimeter-wave radar obtains the presence sensing signal, the presence sensing signal is transmitted to the SparkLink-aware access control controller through the third SparkLink module, thereby achieving legal unlocking without using a SparkLink digital key or through a remote management center.

[0101] In some embodiments, the access control main device described in the above embodiments includes an access control relay switch and a door lock assembly; wherein, after receiving a SparkLink wireless unlocking signal, a remote unlocking signal, or a presence sensing signal, the SparkLink-aware access control controller controls the state of the access control relay switch by outputting a control signal, thereby achieving control over the on / off state of the door lock assembly.
