[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0024] According to an embodiment of the present invention, an embodiment of a method for managing target security domains of smart doors and windows based on UWB technology is provided. 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.

[0025] In this embodiment, a method for managing target security domains of smart doors and windows based on UWB technology is provided. Figure 1 is a flow chart of a method for managing a target security domain of an intelligent door and window based on UWB technology according to an embodiment of the present invention. The method is executed by a first door and window. The members of the target security domain include the first door and window and the second door and window. Figure 1 As shown, the process includes the following steps:

[0026] Step S101, obtaining first position information in a UWB signal sent by a second door or window; the first position information includes phase information and flight time.

[0027] The first door and window and the second door and window are both members of the target security domain, which is an area with a clear range and security protection level that includes smart doors and windows. Members in the security area achieve internal security communication through UWB (ultra-wideband) technology. The first door and window and the second door and window are both equipped with UWB near-field communication modules for communication between the doors and windows. When the second door and window sends a UWB signal, the first door and window receives the signal and obtains the first position information. Optionally, the first position information includes the phase information and flight time of the UWB signal.

[0028] Step S102: Calculate the azimuth angle and relative distance between the first door and window and the second door and window based on the first position information.

[0029] The azimuth angle represents the direction of the second window relative to the first window. The azimuth angle of the second window relative to the first window can be calculated by calculating the phase and the position of the first window. The flight time is the propagation time of the UWB signal from the second window to the first window. Combined with the propagation speed of the signal, the relative distance between the two windows can be calculated.

[0030] Step S103, determining the relative position relationship between the first door and window and the second door and window in the target safety zone by comparing the azimuth angle and the relative distance.

[0031] Combining the comparison results of the azimuth and relative distance, the relative position relationship of the two doors and windows in the target security domain can be determined. For example, they may be located adjacent to each other in the same room, diagonally in the room, or distributed in different rooms but with clear relative positions.

[0032] Step S104: receiving an incoming message, and judging whether the incoming message is in the target security domain based on the relative position relationship.

[0033] Based on the relative position relationship determined previously, the position of the received external message is determined. The scope of the target security domain is the set of relative position relationships of all members in the target security domain. An external message is a UWB signal sent by a device that is not a member of the target security domain temporarily. After receiving the UWB signal of the external message, the relative position relationship of the external message relative to the members in the security domain is calculated, and matched with the scope of the target security domain to determine whether the external message is in the target security domain. If the external message matches the relative position relationship in the target security domain, it is considered that the message is in the target security domain; otherwise, it is considered that the message is outside the target security domain.

[0034] Step S105: If the incoming message does not belong to the target security domain, the incoming message is rejected.

[0035] If it is determined that the incoming message does not belong to the target security domain, that is, the message comes from an unknown or unauthorized device outside the target security domain, rejecting the incoming message means refusing to add the sending device of the incoming message as a member of the target security domain.

[0036] The present embodiment provides a method for managing target security domains of smart doors and windows based on UWB technology. The method calculates the relative position relationship between doors and windows by utilizing the phase information of UWB signals, and determines whether external messages are within the target security domain based on the position relationship, thereby preventing interference and attacks from illegal external messages and improving the security of wireless communications between smart doors and windows.

[0037] In an optional implementation, the process of step S104 includes:

[0038] Step S1041, when an external message is received, extracting external location information corresponding to the external message.

[0039] When an external message is received, the corresponding external phase information is first extracted from it. The external phase information can reflect the relative position relationship between the message source and the first door and window, and is the basis for subsequent judgment of the message source device.

[0040] Step S1042, comparing the external phase information with the first position information in the target security domain.

[0041] After the external phase information is extracted, it is compared with the known first position information in the target security domain. The comparison process may include calculating the phase difference, analyzing the phase change trend, etc., to determine the similarity between the external phase information and the phase information in the target security domain.

[0042] Step S1043: If the external phase information matches the first position information, it is determined that the external message is in the target security domain.

[0043] If the external phase information matches the first position information in the target security domain, which means that the two are consistent in position, it can be determined that the external message comes from a member in the target security domain.

[0044] In an optional embodiment, Figure 2 is a flow chart of a method for processing a newly created domain according to an optional implementation mode of the present invention, such as Figure 2 As shown, the process includes the following steps:

[0045] Step S201: Detecting a new domain.

[0046] The smart door and window security system detects that a new security domain has been created or added to the system environment. At this time, it is necessary to first determine whether there is a domain with this name nearby and perform corresponding processing.

[0047] Step S202: Identify the name of the newly created domain and compare it with the name of the target security domain.

[0048] The name of the new domain is identified (it may be an identifier, domain name, or other form of name) and compared with the name of the existing target security domain to confirm whether the new domain should be integrated into the security domain of the system.

[0049] Step S203A: If the names are inconsistent, the name and password of the newly created domain are saved as the security domain.

[0050] If the name of the newly created domain does not match the name of the target security domain, the system treats the newly created domain as a new, independent security domain and saves its name and password.

[0051] Step 203B: If the names are consistent, compare the password of the newly created domain with the password of the target security domain.

[0052] Step 204A, if the passwords are consistent, then the members of the newly created domain are added to the target security domain; the members of the newly created domain include the third door and window.

[0053] If the password of the newly created domain matches the password of the target security domain, the system will add the members of the newly created domain (including the third door and window in this embodiment) to the target security domain. This is a key step in integrating the newly created domain into the target security domain. After adding members, these members will have the permissions and resources of the target security domain.

[0054] Step 204B: If the passwords are inconsistent, a re-enter password instruction is issued.

[0055] If the password for the newly created domain does not match the password for the target security domain, a command is issued to prompt the user to re-enter the password.

[0056] In an optional embodiment, Figure 3 is a flow chart of a UWB signal verification method according to an optional embodiment of the present invention, such as Figure 3 As shown, the process includes the following steps:

[0057] Step S301, setting verification parameters in the target security domain; the verification parameters include communication format rules of UWB signals.

[0058] A check parameter is set in the target security domain. The check specifies the communication format of the UWB signal and clarifies the specific rules that the signal must follow during transmission. In UWB communication, multiple bits are combined into a data packet or data frame according to the rules to ensure that the structure and format of the data packet are consistent with the receiving end. In order to increase the reliability of the signal, redundant bits can be introduced into the communication format rules of the UWB signal. Redundant bits can be implemented through various coding techniques (such as Hamming code, CRC code, etc.) for error detection or correction. At the receiving end, the system can use these redundant bits to determine whether the signal is erroneous and perform corresponding processing.

[0059] Step S302: verifying the UWB signal sent by the member of the target security domain based on the verification parameter.

[0060] According to the previously set verification parameters, the UWB signals sent by all members in the target security domain are verified to confirm whether each received signal fully complies with the previously set communication format rules. The verification process may include receiving and parsing the signal, and comparing the parsed signal information with the preset verification parameters.

[0061] In an optional implementation, the process of step S302 includes:

[0062] Step S3021, receiving the UWB signal of the second door or window, and verifying its communication format based on the verification parameters.

[0063] Step S3022: If the communication format does not conform to the rules, the UWB signal of the second door and window is discarded.

[0064] If the signal completely matches the verification parameters and complies with the communication format rules, the signal will be considered a valid signal and the subsequent processing flow will continue; if the signal does not match the verification parameters, the signal will be considered an invalid signal, and the system may trigger the corresponding error handling mechanism, such as alarm, signal discard or request for resending. Invalid signals will not be used for subsequent processing or control processes to prevent invalid signals from interfering with the normal operation of the system.

[0065] In an optional implementation, the process of step S204A includes:

[0066] Step a11: the first door and window and the second door and window receive and save the azimuth angle and relative distance of the third door and window.

[0067] Step a12: the third door and window receives and stores the azimuth angle and relative distance of the first door and window.

[0068] Step a13: the third door and window receives and stores the azimuth and relative distance of the second door and window.

[0069] When the third door and window appears, during the domain joining operation, the third door and window needs to save the azimuth and relative distance of the first door and window, and also save the azimuth and relative distance of the second door and window. Similarly, when the members in the target security domain are increased, any member saves the azimuth and relative distance of any other members in the domain.
