In addition, a single step described in this specification may be decomposed into multiple steps for description in other embodiments; multiple steps described in this specification may also be combined into a single step in other embodiments describe.

Fig. 1 is a schematic diagram of an air conditioning unit system 100 provided by an embodiment of the present application. The air conditioning unit system 100 includes a maintenance terminal 11 , an air conditioning unit 15 and an authorization terminal 13 . Wherein, the air conditioning unit 15 includes a main controller 1511 and replaceable functional components (not shown), and the functional components may include an equipment controller 1512 . The main controller 1511 is used to control the work of the entire air conditioning unit 15, and the equipment controller 1512 is used to control the functional components to complete a specific function of the air conditioning unit 15, such as wireless communication function, wired communication function, frequency conversion function, vibration detection function wait. Functional components include input and output expansion boards, wired communication boards, wireless communication boards, touch screens, frequency converters, heaters, etc. In some embodiments, the master controller 1511 is associated with the device controller 1512, and the two can communicate with each other after association.

The air conditioning unit 15 includes various types of operation. For example, after replacing the functional parts or the device controller 1512 of the air conditioning unit 15, the device controller 1512 included in the replaced functional part or the replaced device controller 1512 is associated with the main controller 1511, so that the main controller 1511 Can communicate with the replaced device controller 1512 after association. For another example, after replacing the main controller 1511 of the air conditioning unit 15, an association is established between the replaced main controller 1511 and the original device controller 1512 on the air conditioning unit 15, so that the replaced main controller 1511 and the original The device controller 1512 may communicate after association. Another example is to update the software program or software configuration of the main controller 1511 . For another example, the software program or software configuration of the device controller 1512 is updated. The authorization terminal 13 authorizes at least some operating-type functional components for the air conditioning unit 15 . In some embodiments, after the authorization terminal 13 authorizes the operation type for the air conditioning unit 15, the maintenance terminal 11 sends an operation request to the main controller 1511, so that the main controller 1511 performs an operation corresponding to the operation type. Specifically, the staff can establish a communication connection between the maintenance terminal 11 and the main controller 1511 of the air conditioning unit 15, and send an operation request to the main controller 1511, so that the main controller 1511 performs an operation corresponding to the operation type. The maintenance terminal 11 may include a laptop computer, a mobile phone, etc. used by staff when operating the air conditioning unit 15 .

In some embodiments, the type of operation of the air-conditioning unit 15 can be authorized and controlled to prevent users from performing maintenance operations on the air-conditioning unit 15 through informal channels, such as preventing users from replacing the air-conditioning unit 15 through unauthorized third-party after-sales service providers. Or modify the main controller 1511 and/or the device controller 1512 of the air conditioning unit 15 and/or the functional components including the device controller 1512 . Specifically, for example, when replacing the functional components including the device controller 1512 or the device controller 1512 of the air conditioning unit 15, even if the functional components including the device controller 1512 are replaced from the hardware, the main controller 1511 is not authorized to be connected with the replacement After the device controller 1512 is associated, the main controller 1511 may interrupt the communication with the replaced device controller 1512, so that the replaced device controller 1512 still cannot work normally. For another example, when updating the software program on the main controller 1511, if the authorization is not passed, the main controller 1511 may not be able to obtain the software program used for updating, thus causing the software program update to fail. For another example, the main controller 1511 may be configured to check whether the authorization is passed when updating the software program or software configuration, and not perform the corresponding operation if the authorization is not passed.

In some embodiments, an air conditioning unit system 100 includes multiple authorization terminals 13 . After at least part of the authorization terminal 13 authorizes all the operation types for the air conditioning unit 15, the maintenance terminal 11 sends a request to the main controller 1511, so that the main controller 1511 executes the operation corresponding to the operation type. The authorizing end 13 may include multiple authorizing ends of different levels, for example, the authorizing end 13 of the first level and the authorizing end 13 of the second level. For different operation types of air-conditioning units 15 or for different operation types of the same air-conditioning unit 15 , authorization can be performed through authorization terminals 13 with different levels. For example, for the operation type of the first air-conditioning unit 15, the master controller 1511 of the first air-conditioning unit 15 is allowed to execute the For the operation type of the second air-conditioning unit 15, the second air-conditioning unit 15 can be allowed to The main controller 1511 performs an operation corresponding to the operation type.

In some embodiments, the level number of the authorization end 13 for authorizing the operation type of the air conditioning unit 15 can be determined according to the unit type, cooling tonnage and predetermined rules of the air conditioning unit 15 .

In some embodiments, the air conditioning unit system 100 further includes a server 12 and an authorization receiving terminal 14 . The server 12 can establish a communication connection with the authorization terminal 13 and the maintenance terminal 11 respectively, at least for receiving and storing the authorization information sent by the authorization terminal 13 . The authorization receiving end 14 can establish a communication connection with the authorizing end 13 for receiving authorization information (such as an authorization code) issued by the authorizing end 13 . The authorization receiving terminal 14 may include a client terminal where a staff member's mailbox is located, a staff member's mobile phone, and the like. The authorization end 13 sends the authorization information to the authorization receiving end 14 through email, short message, etc., so that the staff can obtain the authorization information. The staff can input the obtained authorization information into the maintenance terminal 11, so that the maintenance terminal 11 receives the authorization information.

In some embodiments, the authorization information stored on the server 12 is verified for the authorization information received by the maintenance terminal 11, and after the verification of the authorization information received by the maintenance terminal 11 is passed, the maintenance terminal 11 sends an operation request to the main controller 1511, so that the main controller 1511 executes the operation corresponding to the operation type. If the verification of the authorization information received by the maintenance terminal 11 fails, the maintenance terminal 11 does not send an operation request to the main controller 1511 . In this way, problems such as falsification of authorization information and wrong input of authorization information by the staff can be prevented.

In some embodiments, the server 12 also stores software programs and software configurations that need to be updated on the main controller 1511 and/or the device controller 1512 . The server 12 determines the software program or software configuration that needs to be updated on the main controller 1511 and/or the device controller 1512 according to the authorization scope of the authorization code, and sends the corresponding software program or software configuration to the maintenance terminal 11, so that the maintenance terminal 11 Send relevant information to the main controller 1511, and the main controller 1511 updates the software program and/or software configuration. Store the software program or software configuration that needs to be updated on the remote server 12, and the server 12 will issue the software program or software configuration within the authorized range according to the authorization range of the authorization code, which can prevent the software program and/or software configuration from being Illegal copying.

Fig. 2 is a flow chart of a unit control method provided by an embodiment of the present application. The unit control method can be applied to the air conditioning unit system 100 in FIG. 1 . Referring to Figure 1 and Figure 4, the unit control method includes:

Step S21 , the maintenance terminal 11 sends an authorization code acquisition request to the authorization terminal 13 , and the authorization code acquisition request includes data indicating the type of operation for the air conditioning unit 15 . In some embodiments, the type of operation includes at least one of the following:

the type of operation to establish the association between the device controller 1512 and the master controller 1511;

Update the operation type of the software program included in the main controller 1511;

Update the operation type of the software configuration included in the main controller 1511;

update the type of operation of the software program included in the device controller 1512;

An operation type to update the software configuration included in the device controller 1512 .

It should be noted that, in some other embodiments, the operation type may also include other operation types, and this application does not limit the operation type.

For convenience of description, the operation type data is defined as the data indicating the operation type for the air conditioning unit 15 .

In some embodiments, the maintenance terminal 11 communicates with the authorization terminal 13 . Software programs are installed on the maintenance terminal 11 . The staff can select or input the operation type for the air conditioning unit 15 through the client interface on the maintenance terminal 11, for example, when replacing the device controller 1512, select the device controller 1512 that needs to be associated with the main controller 1511 (that is, after the replacement device controller 1512). The logic of the software program may include: at least receiving operation type data, and sending an authorization code acquisition request including at least the operation type data to the authorizing terminal 13 .

In some embodiments, the authorization code acquisition request further includes a unit coupling code, which is used to identify the air conditioning unit 15 . The unit coupling code may be input by the staff through the client interface of the maintenance terminal 11 . The unit coupling codes of each air conditioning unit 15 may be different. The unit coupling code of the air-conditioning unit 15 can be set before the air-conditioning unit 15 leaves the factory; the unit coupling code of the air-conditioning unit 15 can also be updated after the air-conditioning unit 15 leaves the factory. Specifically, when the air-conditioning unit 15 leaves the factory, a two-dimensional code can be set on the hardware device of the air-conditioning unit 15, so that when the staff operates the air-conditioning unit 15, by scanning the two-dimensional code, they can be connected to the corresponding storage of the air-conditioning unit. 15 on the server (such as the server 12) of the unit coupling code to obtain the unit coupling code of the air conditioning unit 15. By periodically updating the unit coupling code of the air conditioning unit 15 stored on the server, the purpose of updating the unit coupling code of the air conditioning unit 15 after the air conditioning unit 15 leaves the factory can be achieved.

In some embodiments, the unit coupling code is obtained based on at least one of the serial number of the air conditioning unit 15, the configuration of the air conditioning unit 15, the hardware serial number of the air conditioning unit 15, and the time data representing the aging of the unit coupling code. Wherein, the effective duration of the unit coupling code can be determined according to the time data representing the time limit of the unit coupling code, for example, 180 days.

In this embodiment, after encrypting the serial number of the air-conditioning unit 15, the configuration of the air-conditioning unit 15, the supporting hardware serial number of the air-conditioning unit 15, and the time data representing the aging of the coupling code of the air-conditioning unit through the set encryption method, the air-conditioning unit is obtained 15 unit coupling code.

In step S22, the authorizing terminal 13 generates an authorization code corresponding to the operation type. In some embodiments, the authorization code corresponding to the type of operation is derived based at least on the crew coupling code and/or the type of operation data. For example, the unit coupling code can be encrypted by a set encryption method, and the encrypted data can be used as the authorization code of the corresponding air conditioning unit. For different operation types of the air conditioning unit 15, the authorization codes may be different. It can be known from the above related description that because the unit coupling code is time-sensitive, for the same operation type of the same air conditioning unit 15, the authorization codes generated based on different unit coupling codes in different time periods may be different. In this way, the security is higher. Each authorization code can authorize the range of operations that the air conditioning unit 15 can perform. For example, based on the authorization code A, only the software program A on the main controller 1511 can be updated; based on the authorization code B, only the functional components of the air conditioning unit 15 can be replaced. b.

In this embodiment, the authorization code corresponding to the operation type includes N sub-authorization codes generated based at least on the unit coupling code and the operation type data. Wherein, the N sub-authorization codes are generated by N authorization terminals 13 of different levels that authorize the operation type of the air-conditioning unit. The value of N is an integer greater than or equal to 1. For example, the authorization terminal 13 that authorizes the operation type includes a first-level authorization terminal 13 and a second-level authorization terminal 13, and the value of N is 2. The authorization end 13 of each level generates a sub-authorization code, and each sub-authorization code may be different. According to the relevant description of the authorizing terminal 13 in FIG. 1, it can be known that, due to different operation types for different air-conditioning units 15 or different operation types for the same air-conditioning unit 15, authorization can be performed through the authorization terminals 13 with different levels of numbers, so each The number of sub-authorization codes included in the authorization code can be different.

In some embodiments, the authorization terminal 13 of the Nth level generates a sub-authorization code of the corresponding level based on at least the unit coupling code, the operation type data and the sub-authorization code generated by the authorization terminal 13 of the previous N-1 levels, for example, The second-level authorization terminal 13 generates a second-level sub-authorization code at least according to the unit coupling code, operation type data and the sub-authorization code generated by the first-level authorization terminal 13 . Here, since the authorization terminal 13 of the first level does not have the authorization terminal 13 of the previous level, the authorization terminal 13 of the first level can generate a sub-authorization code of the first level based on the unit coupling code and the operation type data. For the convenience of description, the sub-authorization code generated by the authorization terminal 13 of the Nth level is defined as the sub-authorization code of the Nth level.

In this embodiment, the sub-authorization code of the Nth level can be obtained by encrypting at least the unit coupling code, the operation type data and the sub-authorization codes of the first N-1 levels through the preset authorization code encryption method . In some embodiments, the authorization terminal 13 may include multiple preset authorization code encryption methods.

In step S23, the authorization terminal 13 issues an authorization code, so that the maintenance terminal 11 receives the authorization code. The authorization terminal 13 of each level can respectively issue the corresponding sub-authorization code of the level. In this embodiment, the authorization terminal 13 of each level sends the corresponding sub-authorization code to the authorization receiving terminal 14 respectively. The staff can obtain the sub-authorization code issued by each authorization terminal 13 through the authorization receiving terminal 14, and input each sub-authorization code into the maintenance terminal 11 through the client interface of the maintenance terminal 11, so that the maintenance terminal 11 receives each sub-authorization code. A sub-authorization code issued by the authorization terminal 13. In some other embodiments, the authorization terminal 13 at each level may also directly send the corresponding sub-authorization code to the maintenance terminal 11 respectively.

Step S24, if the authorization code received by the maintenance terminal 11 passes the verification, the controller 151 executes an operation corresponding to the operation type. In some embodiments, after the authorization terminal 13 generates the authorization code, the authorization terminal 13 sends the authorization code to the server 12, so that the server 12 stores the authorization code. The authorization code stored in the server 12 can be used to verify the authorization code received by the maintenance terminal 11 . Specifically, after the maintenance terminal 11 receives the authorization code, the maintenance terminal 11 sends an authorization code verification request to the server 12 . The authorization code verification request includes the authorization code to be verified. The server 12 checks the authorization code to be verified in the authorization code verification request based on the stored authorization code, for example, the server 12 uses the stored authorization code and the authorization code to be verified included in the authorization code verification request to The same authorization code decryption method is used to decrypt, and the two decrypted authorization codes are compared. If the two are the same, it is determined that the authorization code has passed the verification. For another example, the server 12 can also compare the number of sub-authorization codes included in the decrypted authorization code with the number of authorization levels corresponding to the operation type. If the two do not match, it is determined that the authorization code verification fails. If the authorization code in the authorization code verification request passes the verification, the server 12 returns a message that the authorization code verification is passed to the maintenance terminal 11 .

In some embodiments, if the maintenance terminal 11 receives the message that the authorization code has passed the verification returned by the server 12, it determines that the authorization code has passed the verification. The maintenance terminal 11 sends an operation request to the controller 151, and the controller 151 executes an operation corresponding to the operation type.

In some embodiments, after the verification of the authorization code is passed, the maintenance terminal 11 at least sends the authorization code to the controller 151, so that the controller 151 performs an operation corresponding to the operation type at least based on the authorization code. For example, make the main controller 1511 establish an association between the main controller 1511 and a certain replacement device controller 1512 based on the authorization code.

In some embodiments, after the verification of the authorization code is passed, the server 12 determines the operation corresponding to the operation type of the air conditioning unit 15 based on the authorization code, and the authorization code verification passed message returned to the maintenance terminal 11 includes the controller 151 executing The data required for the operation corresponding to the operation type. For example, when updating the software program on the main controller 1511 , the server 12 includes the software program on the main controller 1511 that needs to be updated in the message returned to the maintenance terminal 11 . The server 12 sends the software program to be updated to the main controller 1511 through the maintenance terminal 11, and the main controller 1511 performs the update. In this way, the main controller 1511 cannot update unauthorized software programs, thereby ensuring that the operations performed on the main controller 1511 are authorized operations.

In some embodiments, the controller 151 can also be set to: when performing an operation corresponding to the operation type, first verify the authorization code, if the verification is passed, the controller 151 executes an operation related to the operation type, On the contrary, the controller 151 does not perform an operation related to the operation type. In this way, unauthorized operations can be prevented.

In the unit control method in some embodiments of the present application, when operating the air conditioning unit 15, it is necessary to obtain the authorization code corresponding to the operation type. The type of operation (such as changing the configuration of the main controller 1511, etc.) can be executed successfully, which can prevent the user from arbitrarily replacing or changing the controller of the air conditioning unit 15 or some functional parts including the controller, and reduce the irregular operation of the air conditioning unit 15. risks of. At the same time, it can also reduce the loss rate of after-sales maintenance business of air-conditioning manufacturers.

Fig. 3 is a flow chart of a unit control method provided by another embodiment of the present application. The unit control method in Fig. 3 applies the maintenance terminal 11 in Fig. 1, referring to Fig. 1 and Fig. 3, the unit control method includes:

Step S31 , based on the operation type for the air-conditioning unit, send an authorization code acquisition request to the authorization end, so that the authorization end generates an authorization code corresponding to the operation type, and the authorization code acquisition request includes data indicating the operation type for the air-conditioning unit. For details, refer to the relevant description of the maintenance terminal 11 in FIG. 2 , which will not be repeated here.

Step S32, receiving the authorization code corresponding to the operation type issued by the authorization terminal. For details, refer to the relevant description of the maintenance terminal 11 in FIG. 2 , which will not be repeated here.

Step S33 , verifying the authorization code, so that after the verification of the authorization code passes, the controller 151 executes an operation corresponding to the operation type. In some embodiments, the maintenance terminal 11 verifies the authorization code, which may be that the maintenance terminal 11 sends an authorization code verification request to the server 12 . The authorization code verification request includes the authorization code to be verified. If receiving the message that the authorization code verification is passed returned by the server 12, the maintenance terminal 11 determines that the authorization code verification is passed. For specific principles, reference may be made to the related description in FIG. 2 , which will not be repeated here.

Fig. 4 is a flow chart of a unit control method provided by another embodiment of the present application. The unit control method in FIG. 4 can be applied to the controller 151 of the air-conditioning unit 15 in FIG. 1. Referring to FIGS. 1 and 4, the unit control method includes:

Step S41 , receiving an authorization code that passes the verification, where the authorization code corresponds to the operation type for the air conditioning unit 15 . For the operation type of the air-conditioning unit 15, refer to the relevant description of FIG. 2 above, and details are not repeated here. For different operation types of the air conditioning unit 15, the authorization codes may be different.

Step S42 , based on the authorization code, perform an operation corresponding to the operation type for the air conditioning unit 15 . In this embodiment, the operation type includes an operation type for establishing an association between the device controller 1512 and the main controller 1511 . It should be noted that the device controller 1512 here is an authorized device controller 1512 that can establish an association with the main controller 1511, for example, a device controller 1512 that is replaced through a regular channel, and for example, the The controller 1511 establishes an association with the original equipment controller 1512 of the air conditioning unit 15 . Associating the main controller 1511 with the device controller 1512 can prevent users from arbitrarily replacing or changing the device controller 1512, the functional components including the device controller 1512, and the main controller 1511 without authorization. The principle is shown in FIG. 1 Related descriptions are not repeated here.

In some embodiments, a coupling code identifying each device controller 1512 may be generated and assigned to each device controller 1512 based on the authorization code. The association between the master controller 1511 and the device controller 1512 is established based on the coupling code. Specifically, the authorization code includes a first authorization code, where the first authorization code may be generated based on the first group coupling code. A first coupling code identifying device controller 1512 may be generated based on the first authorization code. Furthermore, based on the first coupling code, an association between the device controller 1512 and the main controller 1511 is established. If multiple device controllers 1512 are included, a first coupling code may be generated for each device controller 1512 based on the first authorization code. The first coupling codes of each device controller 1512 are different, or the first coupling codes of at least some of the device controllers 1512 may be the same.

In some embodiments, the first authorization code may be encrypted by using a preset coupling code encryption algorithm to obtain the first coupling code of the device controller 1512 .

FIG. 5 is a flow chart of establishing an association between the device controller 1512 and the main controller 1511 in FIG. 1 . In this embodiment, the main controller 1511 executes the method for establishing an association between the device controller 1512 and the main controller 1511 . Referring to FIG. 5, the method for establishing an association between the device controller 1512 and the main controller 1511 may include:

In step S51, the main controller 1511 encrypts the first coupling code through the first encryption algorithm to obtain the main encrypted coupling code. The first encryption algorithm here may be preset by the main controller 1511 before leaving the factory. In some embodiments, the main controller 1511 may include multiple encryption algorithms for encrypting the first coupling code. One of the encryption algorithms may be selected to encrypt the first coupling code.

Step S52, the main controller 1511 sends the main encryption coupling code to the device controller 1512, so that the device controller 1512 decrypts the main encryption coupling code through the first decryption algorithm to obtain the device coupling code, and uses the second encryption algorithm to couple the device The code is encrypted to obtain the device encryption coupling code. In some embodiments, corresponding encryption algorithms and decryption algorithms may be preset before the device controller 1512 leaves the factory.

In step S53, the main controller 1511 receives the device encryption coupling code returned by the device controller 1512.

In step S54, the main controller 1511 decrypts the device encrypted coupling code through the second decryption algorithm to obtain the main coupling code.

Step S55 , if the first coupling code is the same as the main coupling code, the main controller 1511 establishes an association between the device controller 1512 and the main controller 1511 .

It can be understood that the device controller 1512 associated with the main controller 1511 may be associated with the main controller 1511 based on the authorization code. If the device controller 1512 is not authorized, it cannot establish an association with the main controller 1511 . For an unassociated device controller 1512 , the master controller 1511 may stop communicating with the device controller 1512 .

In some embodiments, after the device controller 1512 decrypts the master encrypted coupling code to obtain the device coupling code, it stores the device coupling code. At a preset time point after the association between the device controller 1512 and the main controller 1511 is established, the main controller 1511 acquires the device coupling code stored on the device controller 1512 . The main controller 1511 detects that the device controller 1512 includes the function of the device controller 1512 by detecting whether there is a device coupling code on the device controller 1512, or whether the device coupling code stored on the device controller 1512 is the same as the first coupling code. Whether the part has been replaced. Wherein, the preset time point after the association is established between the device controller 1512 and the master controller 1511 may start from the time when the association is established between the device controller 1512 and the master controller 1511, every preset time period (for example, every The time point obtained after 30 days). If the first coupling code is different from the device coupling code, the master controller 1511 cancels the association between the master controller 1511 and the device controller 1512 . In this way, the user can be prevented from replacing the device controller 1512 of the air conditioning unit 15 or the functional components including the device controller 1512 at will.

In some embodiments, it can be known from the above related description that the unit coupling code of the air conditioning unit 15 may have a timeliness, for example, 180 days. The server storing the unit coupling code can regularly update the unit coupling code. Based on the updated unit coupling code, the authorization request can be resent through the maintenance terminal 11 to obtain a new authorization code to update the association between the main controller 1511 and the device controller 1512, that is, to regenerate a new user ID for the device controller 1512. The coupling code used to identify the device controller 1512. In this way, the coupling code used to identify the device controller 1512 is in a dynamically changing state, which can prevent the coupling code of the device controller 1512 from being maliciously cracked, and thus allow unauthorized device controllers 1512 to communicate with the main controller 1511 .

In some embodiments, the authorization code includes a second authorization code. The second authorization code here is generated according to the second group coupling code. The second unit coupling code may be a unit coupling code after updating the first unit coupling code. A second coupling code identifying device controller 1512 may be generated based on the second authorization code. At the same time, the association between the device controller 1512 and the main controller 1511 established based on the first coupling code is canceled, and the association between the device controller 1512 and the main controller 1511 is established based on the second coupling code.

In some embodiments, the association between the device controller 1512 and the master controller 1511 may be updated by the master controller 1511 based on the second authorization code. The main controller 1511 may regularly prompt to update the authorization code, so that the staff can submit an authorization application based on the new coupling code.

In some embodiments, the association between the main controller 1511 and some device controllers 1512 can be updated based on the above-mentioned second authorization code, and the device controllers 1512 that have not been associated with the main controller 1511 can continue to be based on the first authorization code. Associate with the master controller 1511. That is, some device controllers 1512 of the air-conditioning unit 15 are allowed to associate with the main controller 1511 based on the first authorization code, and some device controllers 1512 are allowed to associate with the main controller 1511 based on the second authorization code.

In some embodiments, the slave device controller 1512 can detect whether the master controller 1511 regularly updates the authorization code. Here it is assumed that the latest authorization code on the main controller 1511 is the first authorization code, and the first coupling code has been generated based on the first authorization code. The device controller 1512 sends a coupling code update request to the main controller 1511 . Here, the coupling code update request may be that the device controller 1512 requests the main controller 1511 to generate a coupling code for identifying the device controller 1512 according to the acquired latest authorization code (ie, the first authorization code). After receiving the request, the main controller 1511 determines whether the time point at which the device controller 1512 sends the coupling code update request is within a preset time range. The preset time range may start from the time point when the device controller 1512 establishes association with the main controller 1511, which is greater than or equal to the time after a preset time period (for example, 90 days). For example, the device controller 1512 may be set to send a coupling code update request to the main controller 1511 on the 91st day after establishing association with the main controller 1511 . If the time when the device controller 1512 sends the coupling code update request is not within the preset time range, it means that the device controller 1512 or the functional parts including the device controller 1512 have been replaced without authorization, and the main controller 1511 Disassociate with device controller 1512 . If the time when the device controller 1512 sends the coupling code update request is within the preset time range, the main controller 1511 encrypts the first coupling code through the first encryption algorithm to obtain the main encrypted coupling code, and sends the main encrypted coupling code to the device controller 1512, so that the device controller 1512 decrypts the main encrypted coupling code through the first decryption algorithm to obtain the device coupling code. The device controller 1512 can compare the device coupling code obtained by decryption with the device coupling code stored locally. If the device coupling code obtained by decryption is the same as the device coupling code stored on the device controller 1512, it means that the main controller 1511 has exceeded If the authorization code is not updated for a preset period of time (for example, more than 90 days), the device controller 1512 may cancel the association between the main controller 1511 and the device controller 1512 .

In some embodiments, it may also be detected from the main controller 1511 whether the device controller 1512 regularly updates the device coupling code.

In some other embodiments, when the device controller 1512 detects that the master controller 1511 does not regularly update the authorization code, it may not cancel the association between the master controller 1511 and the device controller 1512, but give an alarm prompt.
