It should be understood that although the terms first, second, third, etc. may be used in embodiments of the present application to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, a first message may also be referred to as a second message, and similarly, a second message may also be referred to as a first message, without departing from the scope of the present application. Depending on the context, furthermore, the word "if" used may be interpreted as "at … …" or "at … …" or "in response to a determination".
In this embodiment of the present application, a light control method is provided, where a plurality of light controllers in a target scene are divided into K dimming groups, where K may be a positive integer greater than 1, and the method may be applied to a gateway device, as shown in fig. 1, and is a flow diagram of the method, and the method may include:
In one possible implementation, for each dimming group, the dimming control parameter corresponding to the dimming group may include: the group identification corresponding to the dimming group and the switch state corresponding to the dimming group are in an on state or an off state, wherein the on state is used for indicating to turn on the light, and the off state is used for indicating to turn off the light; if the switch state is the on state, the dimming control parameters corresponding to the dimming group may further include: and the brightness parameter value and/or the color temperature parameter value corresponding to the dimming group.
For example, for each dimming group, if the dimming control parameter corresponding to the dimming group includes a brightness parameter value, the brightness parameter value corresponding to the dimming group may be determined as follows: acquiring an initial brightness proportion corresponding to the configured dimming group, wherein the initial brightness proportion is a proportion between an actual brightness value and a brightness maximum value; an actual luminance value (i.e., a luminance parameter value) corresponding to the dimming group is determined based on the initial luminance proportion and the luminance maximum value, and the actual luminance value is used to control the actual luminance of the lamp light.
For example, for each dimming group, if the dimming control parameter corresponding to the dimming group includes a color temperature parameter value, the color temperature parameter value corresponding to the dimming group may be determined as follows: acquiring a target color temperature value corresponding to the configured dimming group; determining a target color temperature value as a color temperature parameter value corresponding to the dimming group; or converting the target color temperature value into a mapped color temperature value in a target value area based on the configured target mapping relation, and determining the mapped color temperature value as a color temperature parameter value corresponding to the dimming group. If the color temperature parameter value is a target color temperature value, the light controller controls the actual color temperature of the light based on the target color temperature value; if the color temperature parameter value is a mapped color temperature value, the lamp light controller controls an actual color temperature of the lamp light based on the target color temperature value after converting the mapped color temperature value into the target color temperature value based on the target mapping relation.
In one possible implementation, before determining K dimming control parameters corresponding to the K dimming groups, the plurality of light controllers in the target scene may be further divided into the K dimming groups based on the configured group division information, and a group identifier may be set for each dimming group. On the basis, for each dimming group, an identification setting message can be sent to the light controllers in the dimming group, and the identification setting message can comprise the group identification corresponding to the dimming group, so that the light controllers analyze and store the group identification corresponding to the dimming group where the light controllers are located from the identification setting message.
In one possible implementation manner, after determining K dimming control parameters corresponding to the K dimming groups, the K dimming control parameters may be encrypted by using the target key to obtain encrypted K dimming control parameters; based on this, the control message may include K encrypted dimming control parameters, and after each light controller receives the control message, the target key is used to decrypt the K encrypted dimming control parameters, so as to obtain the dimming control parameters corresponding to the dimming group where the light controller is located.
For example, before determining K dimming control parameters corresponding to the K dimming groups, user key data may also be obtained from the application platform, and a first key setting message may be sent to all light controllers, where the first key setting message may include the user key data, so that each light controller parses and stores the user key data from the first key setting message. And, a random number may also be generated and a target key is generated based on the random number and the user key data; a second key set message is sent to all of the light controllers, the second key set message may include the random number, such that each light controller parses the random number from the second key set message and generates a target key based on the random number and the user key data.
As can be seen from the above technical solution, in the embodiment of the present application, the same control message may be sent to all light controllers, where the control message includes K dimming control parameters corresponding to K dimming groups, so that each light controller may parse the dimming control parameters corresponding to the dimming group where the light controller is located from the control message, and perform light control based on the dimming control parameters. The unified control of a plurality of light controllers can be realized, the network interference of dimming control to other devices can be effectively reduced, and the overall intelligent home network environment is improved. The whole service scene switching can be completed through one control message, different dimming control parameters of a plurality of dimming groups can be controlled uniformly, uniform gapless control among different dimming groups can be completed, the control success rate and the control efficiency can be improved, the number of the control messages can be greatly reduced, and therefore the network storm risk is reduced.
The above technical solutions of the embodiments of the present application are described below with reference to specific application scenarios.
Referring to fig. 2, a networking schematic diagram of a target scene is shown, where the target scene may be any scene of the smart home, which is not limited. The target scene may include a gateway device 21 (such as an intelligent gateway) and a plurality of light controllers 22 (for example, 6 light controllers are shown in fig. 2, and the number of light controllers may be more or less, which is not limited thereto), and may include other types of devices, which are not limited thereto.
The gateway device 21 is configured to implement management of a plurality of light controllers 22, and can implement light control in cooperation with the light controllers 22. The light controller 22 may be integrated on the lamp for light control. For example, the light controller 22 may be integrated on the LED lamp to perform light control on the LED lamp, the light controller 22 may be integrated on the color lamp to perform light control on the color lamp, the light controller 22 may be integrated on the color temperature lamp to perform light control on the color temperature lamp, and of course, the above is just a few examples, which is not limited thereto.
The gateway device 21 and the light controller 22 need to support the same wireless protocol to communicate wirelessly based on the wireless protocol, which may include, but is not limited to: the type of the Zigbee wireless protocol, bluetooth wireless protocol, wiFi wireless protocol, Z-Wave wireless protocol, etc. is not limited.
In one possible implementation, the gateway device 21 may divide all light controllers within the target scene into K dimming groups based on the configured group division information, where K may be a positive integer greater than 1. The group division information is used to represent the division policy of all the light controllers, and may be group division information configured by a user, or may be group division information autonomously generated by the gateway device 21, which is not limited. When all light controllers in the target scene are divided into K dimming groups, the light controllers can only be divided into one dimming group and cannot be simultaneously divided into a plurality of dimming groups for each light controller.
For example, the group division information is used to indicate that the light controllers in the same room are divided into the same dimming group, and if the target scene has three rooms, the gateway device 21 may divide the light controllers in the first room into the dimming group a1, may divide the light controllers in the second room into the dimming group a2, and may divide the light controllers in the third room into the dimming group a3.
For another example, the group division information is used to indicate that the light controller 22-1 and the light controller 22-2 are divided into the same dimming group, the light controller 22-3 and the light controller 22-4 are divided into the same dimming group, and the light controller 22-5 and the light controller 22-6 are divided into the same dimming group, and then, based on the group division information, the gateway device 21 may divide the light controller 22-1 and the light controller 22-2 into the dimming group a1, may divide the light controller 22-3 and the light controller 22-4 into the dimming group a2, and may divide the light controller 22-5 and the light controller 22-6 into the dimming group a3.
Of course, the above is merely an example, and the following procedure takes the dimming group a1 including the light controller 22-1 and the light controller 22-2, the dimming group a2 including the light controller 22-3 and the light controller 22-4, and the dimming group a3 including the light controller 22-5 and the light controller 22-6 as an example.
After dividing all the light controllers into K dimming groups, the gateway device 21 may also set a group identifier for each dimming group, which is not limited in the setting manner, as long as the group identifiers corresponding to different dimming groups are different, that is, the group identifiers have uniqueness. For example, the group identifier set by the gateway device 21 for the dimming group a1 is 00 (binary value), the group identifier set by the gateway device 21 for the dimming group a2 is 01, and the group identifier set by the gateway device 21 for the dimming group a3 is 10.
After the gateway device 21 sets the group identifier for each dimming group, the gateway device 21 may send an identifier setting message to each light controller in the dimming group, where the identifier setting message may include the group identifier corresponding to the dimming group, so that the light controller parses and stores the group identifier corresponding to the dimming group where the light controller is located from the identifier setting message.
For example, the gateway device 21 transmits an identification setting message based on a wireless protocol (such as Zigbee, bluetooth, wiFi, Z-Wave, etc.) to the light controller 22-1, the identification setting message may include the group identification 00 of the dimming group a1, and the light controller 22-1 may parse the group identification 00 of the dimming group a1 from the identification setting message after receiving the identification setting message, and store the group identification 00 of the dimming group a1 in a designated storage area. Similarly, the light controller 22-2 may store the group identification 00 of the dimming group a1, the light controller 22-3 may store the group identification 01 of the dimming group a2, the light controller 22-4 may store the group identification 01 of the dimming group a2, the light controller 22-5 may store the group identification 10 of the dimming group a3, and the light controller 22-6 may store the group identification 10 of the dimming group a 3.
In summary, each light controller may store the group identifier corresponding to the dimming group where the light controller is located, as shown in fig. 3, the dimming group a1 includes the light controller 22-1 and the light controller 22-2, the dimming group a2 includes the light controller 22-3 and the light controller 22-4, the dimming group a3 includes the light controller 22-5 and the light controller 22-6, the light controller 22-1 and the light controller 22-2 store the group identifier 00 of the dimming group a1, the light controller 22-3 and the light controller 22-4 store the group identifier 01 of the dimming group a2, and the light controller 22-5 and the light controller 22-6 store the group identifier 10 of the dimming group a 3.
In one possible implementation, if the division policy of all light controllers changes, that is, the dimming groups need to be re-divided, the gateway device 21 may divide all light controllers in the target scene into M dimming groups based on the reconfigured group division information, where M may be a positive integer greater than 1, and M and K may be the same or different. After dividing all the light controllers into M dimming groups, the gateway device 21 may further set a group identifier for each dimming group, and for each dimming group, the gateway device 21 may send an identifier setting message to each light controller in the dimming group, where the identifier setting message may include a group identifier corresponding to the dimming group, so that the light controller parses and stores the group identifier corresponding to the dimming group where the light controller is located from the identifier setting message.
Based on the above application scenario, taking an example that a plurality of light controllers in a target scenario are divided into K dimming groups as an illustration, in this embodiment of the present application, a light control method is provided, as shown in fig. 4, and is a schematic flow chart of the light control method, where the light control method may include the following steps:
In step 401, the gateway device determines K dimming control parameters corresponding to the K dimming groups, where the dimming groups correspond to the dimming control parameters one by one, and the dimming control parameters corresponding to different dimming groups are the same or different.
For example, the gateway device 21 determines a dimming control parameter b1 corresponding to the dimming group a1, a dimming control parameter b2 corresponding to the dimming group a2, and a dimming control parameter b3 corresponding to the dimming group a 3; the dimming control parameter b1 is the same as or different from the dimming control parameter b2, the dimming control parameter b1 is the same as or different from the dimming control parameter b3, and the dimming control parameter b2 is the same as or different from the dimming control parameter b 3.
In one possible implementation, for each dimming group, the dimming control parameter corresponding to the dimming group may include a group identifier corresponding to the dimming group, and a switch state corresponding to the dimming group, where the switch state is an on state or an off state. If the switch state is the on state, the dimming control parameter corresponding to the dimming group may further include a brightness parameter value and/or a color temperature parameter value corresponding to the dimming group.
For example, since the dimming control parameters corresponding to each dimming group are obtained in the same manner, step 401 is described taking the dimming control parameter b1 corresponding to the dimming group a1 as an example for convenience of description. For example, the following steps may be adopted to obtain the dimming control parameter b1 corresponding to the dimming group a 1:
In step 4011, the gateway device 21 obtains the group identifier corresponding to the dimming group a 1.
For example, since the gateway device 21 can store the group identifier corresponding to each dimming group, the gateway device 21 can obtain the group identifier corresponding to the dimming group a1, i.e., the group identifier 00.
In step 4012, gateway device 21 obtains the switch state corresponding to dimming group a 1.
For example, the gateway device 21 may receive configuration information (such as configuration information sent by the user to the gateway device 21 through the mobile terminal, or configuration information input by the user on the gateway device 21, etc., without limitation), where the configuration information may include a switch state corresponding to the dimming group a 1. Assuming that the user wishes to turn ON the lights for each light controller in dimming group a1, the switch state may be an ON state (i.e., an ON state), in which case further steps need to be performed to continue to obtain dimming control parameters. Assuming that the user wishes to turn OFF the lights of the light controllers within the dimming group a1, the switch state may be an OFF state (i.e., an OFF state), in which case no further steps are performed, and the dimming control parameter b1 corresponding to the dimming group a1 has been obtained, and the dimming control parameter b1 includes the group identification 00 and the OFF state.
In step 4013, the gateway device 21 obtains the brightness parameter value corresponding to the dimming group a 1.
For example, the gateway device 21 may receive configuration information (such as configuration information sent by the user to the gateway device 21 through the mobile terminal, or configuration information input by the user on the gateway device 21, etc.), where the configuration information may include an initial brightness ratio (i.e., a configured initial brightness ratio) corresponding to the dimming group a1, where the initial brightness ratio may be a ratio between an actual brightness value and a brightness maximum value, such as 50%, 70%, 80%, etc., where 50% represents a ratio between the actual brightness value and the brightness maximum value of 50%, and so on.
After obtaining the initial luminance proportion, the gateway apparatus 21 may determine an actual luminance value corresponding to the dimming group a1 based on the initial luminance proportion and the luminance maximum value, the actual luminance value being used to control the actual luminance of the lamp light, and then determine the actual luminance value as a luminance parameter value corresponding to the dimming group a 1.
For example, the gateway apparatus 21 may determine the actual brightness value corresponding to the dimming group a1 using the following formula (1), and of course, the following formula (1) is merely an example, and the determination manner is not limited.
P actual ＝(P initial *P max ) 100% formula (1)
In formula (1), P actual Represents the actual brightness value corresponding to the dimming group a1, P initial Represents the initial brightness ratio, such as 50%, P, corresponding to the dimming group a1 max Representing the brightness maximum.
For example, assume that the actual brightness value interval is 0-254, i.e. the dimming range of the light controllerAround 0-254, then the brightness maximum P max May be 254. On this basis, if the initial luminance ratio corresponding to the dimming group a1 is 50%, it is determined that the actual luminance value corresponding to the dimming group a1 is 127 (254×0.5), that is, the luminance parameter value corresponding to the dimming group a1 is 127. If the initial brightness ratio corresponding to the dimming group a1 is 70%, it is determined that the actual brightness value corresponding to the dimming group a1 is 178 (254×0.7), that is, the brightness parameter value corresponding to the dimming group a1 is 178, and so on.
In summary, the gateway device 21 may obtain the brightness parameter value corresponding to the dimming group a 1.
In step 4014, the gateway device 21 obtains the color temperature parameter value corresponding to the dimming group a 1.
For example, the gateway device 21 may receive configuration information (such as configuration information sent by the user to the gateway device 21 through the mobile terminal, or configuration information input by the user on the gateway device 21, etc.), where the configuration information may include a target color temperature value (i.e., a configured target color temperature value) corresponding to the dimming group a1, where the target color temperature value is used to control an actual color temperature of the light, for example, the target color temperature value may be 2700K, 4000K, etc.
The range of the target color temperature value may be [2700k,6500k ], that is, any color temperature value in [2700k,6500k ] may be configured as the target color temperature value, and the value of the target color temperature value is not limited.
In one possible embodiment, after obtaining the target color temperature value corresponding to the dimming group a1, the target color temperature value may be used as the color temperature parameter value corresponding to the dimming group a1, that is, the color temperature parameter value is the target color temperature value.
In another possible embodiment, after obtaining the target color temperature value corresponding to the dimming group a1, the gateway device 21 may convert the target color temperature value into a mapped color temperature value in the target value region based on the configured target mapping relationship (i.e., the target function relationship), and use the mapped color temperature value as the color temperature parameter value corresponding to the dimming group a1, that is, the color temperature parameter value is the mapped color temperature value. In this embodiment, the number of transmission bits is reduced by converting the target color temperature value into a mapped color temperature value in the target numerical value region, saving network resources.
For example, assuming that the color temperature parameter value is transmitted through 1 byte (8 bits), the target value region may be 0-255, i.e., 1 byte may represent only 256 values such as 0-255, and since the target color temperature value is in the range of [2700k,6500k ], it is necessary to map [2700, 6500] to 0-255. On this basis, a target mapping relationship (i.e., a target function relationship) may be configured, and the target mapping relationship is used to convert the target color temperature value of the [2700, 6500] interval into a mapped color temperature value of the 0-255 interval, so long as the target mapping relationship is not limited, and the numerical value of the [2700, 6500] interval can be converted into the numerical value of the 0-255 interval.
For example, an example of the target mapping relationship (i.e., the target function relationship) may be shown in formula (2), and of course, the following formula (2) is only an example, and the target mapping relationship is not limited thereto.
W mapping ＝1000000/W target -153 formula (2)
In the formula (2), W mapping Represents the mapped color temperature value, W target Representing the target color temperature value. As can be seen from the formula (2), the range of the target color temperature value is [2700K,6500K]When the target color temperature value is 6500, the mapped color temperature value is 1000000/6500-153, namely the mapped color temperature value is 0, when the target color temperature value is 2700, the mapped color temperature value is 1000000/2700-153, namely the mapped color temperature value is 217, obviously, the target mapping relation can be represented by [2700, 6500]The target color temperature value of the interval is converted into a mapped color temperature value of the interval 0-255.
For example, assuming that the target color temperature value corresponding to the dimming group a1 is 4000K, it is determined that the mapped color temperature value corresponding to the dimming group a1 is 97, that is, the color temperature parameter value corresponding to the dimming group a1 is 97.
In summary, the gateway device 21 may obtain the color temperature parameter value corresponding to the dimming group a 1.
In step 4015, the gateway device 21 obtains the dimming control parameter b1 corresponding to the dimming group a1, where the dimming control parameter b1 includes the group identifier and the off state corresponding to the dimming group a 1. Or, the dimming control parameter b1 includes a group identifier, an on state, a brightness parameter value and a color temperature parameter value corresponding to the dimming group a 1.
Thus, step 401 is completed, and K dimming control parameters corresponding to the K dimming groups may be obtained.
For example, after obtaining K dimming control parameters corresponding to the K dimming groups, the gateway device 21 may generate a control message, where the control message may be a broadcast packet, such as a broadcast packet based on a wireless protocol (e.g. Zigbee, bluetooth, wiFi, Z-Wave, etc.), and the format of the control message is not limited, so long as the control message includes K dimming control parameters. For example, referring to table 1, this is an example of the control message, and of course, table 1 is merely taken as an example, and the content of the control message is not limited.
TABLE 1
In table 1, cmd ID is a binary identification, which may be 2 bytes, for indicating that the current control message is a control message carrying dimming control parameters, and that the current control message may be distinguished from other types of messages by Cmd ID. NUM is a 1 byte value that is used to indicate the number of dimming control parameters that the current control message carries, as indicated by 3 (00000011) to carry 3 dimming control parameters.
For the first dimming control parameter (i.e., dimming control parameter b1 corresponding to dimming group a 1), the dimming control parameter includes group identification 00, switch state ON, brightness parameter value 127 (which may be represented in binary in table 1), and color temperature parameter value 97 (which may be represented in binary in table 1). The group identifier, the switch state, the brightness parameter value and the color temperature parameter value may be 1 byte.
For a second dimming control parameter (i.e. dimming control parameter b2 corresponding to dimming group a 2), the dimming control parameter comprises a group identification 01, a switch state ON, a brightness parameter value 178 (which may be represented in binary in table 1) and a color temperature parameter value 217 (which may be represented in binary in table 1).
For the third dimming control parameter (i.e. the dimming control parameter b3 corresponding to the dimming group a 3), the dimming control parameter comprises a group identification 10, a switch state OFF, a brightness parameter value and a color temperature parameter value being null.
After obtaining the control message shown in table 1, the gateway device may send the control message to all light controllers in all dimming groups, such as light controller 22-1, light controller 22-2, light controller 22-3, light controller 22-4, light controller 22-5, light controller 22-6, and so on.
Illustratively, the light controller 22-1 has previously stored the group identifier 00 of the dimming group a1, so that, after receiving the control message, the light controller 22-1 may parse the first dimming control parameter (i.e., the dimming control parameter b1 corresponding to the dimming group a 1) from the control message, that is, since the group identifier 00 in the dimming control parameter is identical to the group identifier 00 stored in advance by the light controller 22-1, the first dimming control parameter may be parsed, where the dimming control parameter includes the group identifier 00, the ON-off state, the brightness parameter value 127, and the color temperature parameter value 97. Similarly, the light controller 22-2 may parse the first dimming control parameter b1 from the control message after receiving the control message, the light controller 22-3 may parse the second dimming control parameter b2 from the control message after receiving the control message, the light controller 22-4 may parse the second dimming control parameter b2 from the control message after receiving the control message, the light controller 22-5 may parse the third dimming control parameter b3 from the control message after receiving the control message, and the light controller 22-6 may parse the third dimming control parameter b3 from the control message after receiving the control message.
And 404, the light controller performs light control based on the analyzed dimming control parameters.
For example, if the on-OFF state in the dimming control parameter is an OFF state (OFF state) for indicating turning OFF of the lamp, the lamp controller turns OFF the lamp based on the dimming control parameter.
For example, if the ON state in the dimming control parameter is an ON state (ON state) for indicating to turn ON the light, the light controller turns ON the light based ON the dimming control parameter.
When the light controller starts the light based on the dimming control parameter, the light control can be performed based on the brightness parameter value and the color temperature parameter value. For example, the luminance parameter value is an actual luminance value for controlling the actual luminance of the lamp, and thus the lamp controller may adjust the lamp to the actual luminance value.
For example, if the color temperature parameter value is a target color temperature value, the target color temperature value is used for controlling the actual color temperature of the light, so that the light controller controls the actual color temperature of the light based on the target color temperature value, that is, the light controller can adjust the actual color temperature of the light to the target color temperature value. Or if the color temperature parameter value is a mapped color temperature value, the light controller may convert the mapped color temperature value into a target color temperature value based on the target mapping relationship, and after converting the mapped color temperature value into the target color temperature value, the light controller may control an actual color temperature of the light based on the target color temperature value, that is, the light controller may adjust the actual color temperature of the light to the target color temperature value.
Wherein the light controller may maintain a target mapping relationship that is the same as the target mapping relationship maintained by the gateway device 21, based on which the light controller may convert the mapped color temperature value into a target color temperature value. For example, referring to the target mapping relationship shown in the formula (2), the target color temperature value can be obtained after substituting the mapped color temperature value into the target mapping relationship shown in the formula (2).
In one possible implementation manner, when the gateway device sends the control message to all the light controllers in a broadcast manner, there is a risk of losing the control message in a scene of large interference environment, so the gateway device may start a timer after sending the control message. And before the timer is overtime, if the response messages returned by all the light controllers are received, closing the timer. When the timer times out, if a certain light controller or response messages returned by certain light controllers are not received, the gateway equipment independently sends control messages to the light controllers which do not return the response messages until response messages returned by all the light controllers are received, and the control messages are stopped from being sent so as to ensure that all the light controllers receive the control messages.
For each light controller, after receiving the control message sent by the gateway device, a reply message may be returned to the gateway device, where the reply message indicates that the light controller has correctly received the control message.
In a possible implementation manner, after obtaining the K dimming control parameters, the gateway device may further encrypt the K dimming control parameters with the target key to obtain the encrypted K dimming control parameters before step 402. For example, the entire content of the control message shown in table 1 may be encrypted, and for example, only K dimming control parameters may be encrypted, which is not limited.
Based on this, in step 402, when the gateway device sends a control message to all light controllers in all dimming groups, the control message may include K dimming control parameters after encryption.
In step 403, after receiving the control message, each light controller decrypts the K encrypted dimming control parameters by using the target key, and then, the light controller parses the dimming control parameters corresponding to the dimming group in which the light controller is located from the K decrypted dimming control parameters.
The target key may be a symmetric key based on AES, DES, 3DES, IDEA, RC5, RC6, or the like, or an asymmetric key, for example, and the type of the target key is not limited.
Illustratively, the gateway device and all of the light controllers need to obtain the target key, and the target key obtained by the gateway device and the target key obtained by each of the light controllers may be the same.
In one possible implementation, in order to make the target key obtained by the gateway device and the target key obtained by each light controller the target key may be obtained as follows:
step S11, the gateway equipment acquires the user key data from the application platform.
Step S12, the gateway device sends a first key setting message to all light controllers, where the first key setting message may include user key data. For each light controller, after receiving the first key setup message, the light controller parses and stores the user key data from the first key setup message.
Illustratively, the gateway device needs to obtain user key data from the application platform before the light control process, i.e. before step 401 is performed. For example, the user may register on the application platform, and register own user information (such as user identification, mobile phone number, etc., without limitation) on the application platform, and the application platform may generate user key data based on the user information, without limitation.
The user may also register information of the gateway device with the application platform, and the application platform may send user key data to the gateway device based on the information of the gateway device after learning the information of the gateway device.
After obtaining the user key data, the gateway device may store the user key data and send a first key setup message based on a wireless protocol (e.g., zigbee, bluetooth, wiFi, Z-Wave, etc.) to the light controllers, e.g., send the first key setup message to each light controller individually, where the first key setup message may include the user key data. After receiving the first key setting message, the light controller may parse the user key data from the first key setting message and store the user key data.
The gateway device, for example, need only acquire the user key data once and store the user key data, and the subsequent process need not repeatedly acquire the user key data from the application platform. The light controller only needs to acquire the user key data once and store the user key data, and the follow-up process does not need to repeatedly acquire the user key data from the gateway equipment. In summary, the user key data is not changed after being stored.
Step S13, the gateway equipment generates a random number and generates a target key based on the random number and user key data.
Step S14, the gateway device sends a second key setting message to all light controllers, where the second key setting message may include the random number. For each light controller, after receiving the second key set message, the light controller parses the random number from the second key set message and generates a target key based on the random number and user key data (i.e., user key data stored locally by the light controller).
In one possible implementation, the gateway device may generate a random number, and the generation manner of the random number is not limited. After obtaining the random number, the gateway device may generate a target key based on the random number and the user key data, for example, the random number and the user key data may be combined into the target key, the random number may be deformed or the user key data may be deformed and then combined into the target key, without limitation.
The gateway device may also send a second key setup message based on a wireless protocol (e.g., zigbee, bluetooth, wiFi, Z-Wave, etc.) to the light controllers after obtaining the random number, e.g., send the second key setup message to each light controller individually, where the second key setup message may include the random number.
For the light controller, after receiving the second key setting message, the light controller may parse the random number from the second key setting message and generate a target key based on the random number and the user key data, for example, the random number and the user key data may be combined into the target key, the random number may be deformed or the user key data may be deformed, and then the target key may be combined, which is not limited.
In summary, the gateway device may obtain the target key, each light controller may obtain the target key, and the target key obtained by the gateway device is the same as the target key obtained by each light controller.
In another possible implementation, the gateway device may generate a random number, and the generation manner of the random number is not limited. After obtaining the random number, the gateway device may encrypt the random number with the user key data to obtain the local key, and then generate the target key based on the local key and the user key data, for example, the local key and the user key data may be combined into the target key, the local key may be deformed or the user key data may be deformed, and then the target key may be combined, which is not limited.
The gateway device may also send a second key setup message based on a wireless protocol (e.g., zigbee, bluetooth, wiFi, Z-Wave, etc.) to the light controllers after obtaining the local key, e.g., send the second key setup message to each light controller individually, where the second key setup message may include the local key.
For the light controller, after receiving the second key setting message, the light controller may parse the local key from the second key setting message and generate a target key based on the local key and the user key data, for example, the local key and the user key data may be combined into the target key, the local key may be deformed or the user key data may be deformed and then combined into the target key, which is not limited.
In summary, the gateway device may obtain the target key, each light controller may obtain the target key, and the target key obtained by the gateway device is the same as the target key obtained by each light controller.
Illustratively, after the target key is generated, the target key will not change unless the gateway device completely deletes the light controller, e.g., the gateway device resets, clearing the local key.
