[0002] At present, there has been collaborative communication between multiple kitchen appliances to facilitate collaborative control and realize intelligent operation of multiple kitchen appliances. For example, the range hood and the stove communicate collaboratively. The range hood uses its sensor to detect the carbon monoxide concentration near the stove. When the carbon monoxide concentration is too high, the range hood turns on to eliminate the carbon monoxide concentration. If turning on the range hood still cannot effectively reduce the carbon monoxide concentration, the stove is notified to turn off.
[0003] However, this method of establishing collaborative communication is too crude. If multiple range hoods are placed together with multiple stoves, communication confusion will occur.

[0072] It should be particularly noted that any symbols and / or numbers in the specification that are not marked in the accompanying drawings are not drawing marks.
[0073] The optional embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0074] The embodiment provided in this application is an embodiment of a method for establishing a collaborative communication channel for multiple kitchen appliances.
[0075] Combine the following Figure 1 and Figure 2 The embodiments of the present application are described in detail.
[0076] Step S101, in response to obtaining the cooperation request information broadcast by the target kitchen appliance, verification is performed based on the target characteristic parameter value, random parameter value and the preset local identity parameter value of the local appliance in the cooperation request information to obtain a verification result.
[0077] In the field of communication, broadcasting is a non-point-to-point communication method. After the target kitchen appliance broadcasts the collaborative request information, all kitchen appliances with communication receiving functions within the communication range can receive the collaborative request information. Since the target kitchen appliance has not established a collaborative communication channel with this machine, the target kitchen appliance can only send collaborative request information to the surrounding kitchen appliances through broadcast communication.
[0078] In order to ensure that the target kitchen appliance can establish a collaborative communication channel with the kitchen appliance it is looking for, the embodiment of the present application adds target characteristic parameter values and random parameter values to the collaborative request information for mutual authentication with the kitchen appliance it is looking for, so as to establish a safe and reliable collaborative communication channel between the target kitchen appliance and the kitchen appliance it is looking for, ensuring that the control instructions sent by one party can be accurately and effectively received and executed by the other party.
[0079] The target characteristic parameter value and the preset local identity parameter are both unique values.
[0080] The target characteristic parameter value is a unique value generated by the target kitchen appliance.
[0081] The preset local machine identity parameter is a unique value stored in the local machine that represents the local machine identity. For example,
[0082] In some specific embodiments, the target kitchen appliance includes a stove, and the machine includes a range hood.
[0083] For example, the stove sends a collaboration request message via broadcasting. After the range hood receives the collaboration request message, it determines whether the stove is looking for the local machine based on the target feature parameter value, random parameter value and the local machine's preset local identity parameter value in the collaboration request message.
[0084] In some specific embodiments, in response to obtaining the collaborative request information broadcast by the target kitchen appliance, performing verification based on the target characteristic parameter value, the random parameter value and the preset local identity parameter value of the local appliance in the collaborative request information to obtain the verification result includes the following steps:
[0085] Step S101a-1, in response to receiving a power-on signal of the local device, calculating the power-on duration.
[0086] For example, after the range hood receives the power-on signal from the power button, the range hood starts to receive various collaborative request information, prepares to establish a collaborative communication channel, and starts calculating the power-on time.
[0087] Step S101a-2, when the power-on time is less than the preset first delay time, in response to obtaining the cooperative request information periodically broadcast by the target kitchen appliance, verification is performed based on the target characteristic parameter value, random parameter value and the preset local identity parameter value of the local appliance in the cooperative request information to obtain a verification result.
[0088] If the collaboration request information can be received within the preset first delay time, information verification is performed to determine whether there is a target kitchen appliance paired with the machine.
[0089] If the collaborative request information is not received within the preset first delay time, the pairing is determined to have failed, and the device stops verifying the collaborative request information received at a later time. This prevents excessive verification processing from occupying a large amount of resources, causing the device's response delay, and bringing a bad experience to the user.
[0090] In some specific embodiments, performing verification based on the target characteristic parameter value, the random parameter value, and the preset local identity parameter value of the local device in the collaborative request information to obtain the verification result includes the following steps:
[0091] Step S101b-1, extracting a first identity parameter value, a second identity parameter value, other parameter values and a target verification parameter value based on the target feature parameter value.
[0092] The first identity parameter value refers to the identity parameter value of the target kitchen appliance.
[0093] The second identity parameter value refers to the identity parameter value of the local computer. The second identity parameter value is pre-stored in the target kitchen appliance. The target kitchen appliance searches for the collaborative object based on the second identity parameter value to ensure the uniqueness of the object identity. If the collaborative object needs to be replaced, only the second identity parameter value saved in the target kitchen appliance needs to be replaced.
[0094] Other parameter values can be a random parameter value or a parameter value with a specific meaning, but the present implementation is not limited thereto. This increases the uncertainty of each target characteristic parameter value, avoids the information in the collaborative request information being intercepted and cracked, and improves the security of establishing a collaborative communication channel. For example, the stove is looking for the same range hood to establish a collaborative communication channel each time, but the other parameter values in the target characteristic parameter value sent each time are different, that is, the target characteristic parameter values are different, which increases the difficulty of the cracking algorithm and improves the security of establishing a collaborative communication channel between the stove and the range hood.
[0095] The target characteristic parameter value is a hexadecimal value of a preset byte length. For example, the target characteristic parameter value is a hexadecimal value of 16 bytes in length, and the first identity parameter value, the second identity parameter value, other parameter values and the target verification parameter value each occupy a one-byte hexadecimal value.
[0096] Step S101b-2, when the second identity parameter value is consistent with the preset local identity parameter value and the first identity parameter value is within the preset kitchen appliance identity range, a target XOR parameter value is generated based on the preset feature composition order of the target feature parameter value, the first identity parameter value, the second identity parameter value, other parameter values and random parameter values.
[0097] The preset kitchen appliance identity range indicates the identity of the manufacturer. The preset kitchen appliance identity range of each manufacturer is different. For example, the first identity parameter value includes: manufacturer code, kitchen appliance category code and identity code.
[0098] This specific embodiment first verifies whether the target kitchen appliance is looking for the local machine. If so, it verifies whether the first identity parameter value of the target kitchen appliance is within the preset kitchen appliance identity range to avoid receiving similar information from other manufacturers and reduce misjudgment.
[0099] In some specific embodiments, generating a target XOR parameter value based on a preset feature composition order of a target feature parameter value, a first identity parameter value, a second identity parameter value, other parameter values, and a random parameter value comprises the following steps:
[0100] Step S101b-21, according to the preset feature composition order of the target feature parameter value, the first identity parameter value, the second identity parameter value and other parameter values are XOR-calculated in sequence to obtain an intermediate XOR parameter value.
[0101] For example, the target feature parameter value is a hexadecimal value with a length of 16 bytes, and the first identity parameter value, the second identity parameter value, the other parameter values and the target verification parameter value each occupy a one-byte hexadecimal value. If the preset feature composition order of the target feature parameter value is: the first identity parameter value, the second identity parameter value, the other parameter values and the target verification parameter value, then the first identity parameter value and the second identity parameter value are XOR-calculated to obtain a first XOR value, and then the first XOR value and the other parameter values are XOR-calculated to obtain a one-byte intermediate XOR parameter value.
[0102] Step S101b-22, performing XOR calculation on the intermediate XOR parameter value and the random parameter value to obtain the target XOR parameter value.
[0103] For example, if the random parameter value is a one-byte hexadecimal value, the intermediate XOR parameter value and the random parameter value are XORed to obtain a one-byte target XOR parameter value.
[0104] Step S101b-3, fusing the target XOR parameter value with the target characteristic parameter value to obtain the verification parameter value to be verified.
[0105] In some specific embodiments, the target XOR parameter value is merged with the target characteristic parameter value to obtain the verification parameter value to be verified, including the following steps:
[0106] Step S101b-31, converting the target XOR parameter value into a target binary value.
[0107] For example, the target XOR parameter value is a byte value, which is converted into a binary value, for example, the target binary value is 01100100.
[0108] Step S101b-32, extracting the target binary digit of each digital position in the target binary value.
[0109] For example, continuing the above example, the target binary value, from right to left, the binary digit of the first digit ranking is "0", the binary digit of the second digit ranking is "0", the binary digit of the third digit ranking is "1", the binary digit of the fourth digit ranking is "0", the binary digit of the fifth digit ranking is "0", the binary digit of the sixth digit ranking is "1", the binary digit of the seventh digit ranking is "1", and the binary digit of the eighth digit ranking is "0".
[0110] Step S101b-33, converting the target binary number of each digital position into the target hexadecimal number of the corresponding digital position.
[0111] After the conversion, the hexadecimal numbers of the various digital positions are the same as the binary numbers of the corresponding digital positions. For example, continuing the above example, the hexadecimal number of the target hexadecimal number, from right to left, the hexadecimal number of the first digital position is "0x0", the hexadecimal number of the second digital position is "0x0", the hexadecimal number of the third digital position is "0x1", the hexadecimal number of the fourth digital position is "0x0", the hexadecimal number of the fifth digital position is "0x0", the hexadecimal number of the sixth digital position is "0x1", the hexadecimal number of the seventh digital position is "0x1", and the hexadecimal number of the eighth digital position is "0x0".
[0112] Step S101b-34, calculate the sum of the target hexadecimal number of each digital ranking and the number of the corresponding digital ranking in the hexadecimal target characteristic parameter value, and obtain the hexadecimal target sum value of the corresponding digital ranking.
[0113] For example, continuing with the above example, if the target feature parameter value is 0x23456789, the target feature parameter value, the hexadecimal number of the first digit ranking from right to left is "0x9", the hexadecimal number of the second digit ranking is "0x8", the hexadecimal number of the third digit ranking is "0x7", the hexadecimal number of the fourth digit ranking is "0x6", the hexadecimal number of the fifth digit ranking is "0x5", the hexadecimal number of the sixth digit ranking is "0x4", the hexadecimal number of the seventh digit ranking is "0x3", and the hexadecimal number of the eighth digit ranking is "0x2"; for positional calculation, the hexadecimal number of the first digit ranking from right to left is "0x9", the hexadecimal number of the second digit ranking is "0x8", the hexadecimal number of the third digit ranking is "0x7", the hexadecimal number of the fourth digit ranking is "0x6", the hexadecimal number of the fifth digit ranking is "0x5", the hexadecimal number of the sixth digit ranking is "0x4", the hexadecimal number of the seventh digit ranking is "0x3", and the hexadecimal number of the eighth digit ranking is "0x2". The hexadecimal target sum of the first digit = 0x9 + 0x0 = 0x9, the hexadecimal target sum of the second digit = 0x8 + 0x0 = 0x8, the hexadecimal target sum of the third digit = 0x7 + 0x1 = 0x8, the hexadecimal target sum of the fourth digit = 0x6 + 0x0 = 0x6, the hexadecimal target sum of the fifth digit = 0x5 + 0x0 = 0x5, the hexadecimal target sum of the sixth digit = 0x4 + 0x1 = 0x5, the hexadecimal target sum of the seventh digit = 0x3 + 0x1 = 0x4, and the hexadecimal target sum of the eighth digit = 0x2 + 0x0 = 0x2.
[0114] Step S101b-35, extracting the hexadecimal units digit value of the corresponding digital rank from the target and value of each digital rank.
[0115] For example, continuing the above example, the hexadecimal units digit value of each digital rank obtained above is consistent with the target and value of the corresponding digital rank.
[0116] Step S101b-36, combining the units digit value of the corresponding digital rank into a hexadecimal verification parameter value according to the ranking order of each digital rank.
[0117] For example, continuing the above example, the hexadecimal value of the verification parameter is 0x24556889.
[0118] Step S101b-4: when the verification parameter value to be verified is consistent with the target verification parameter value, the verification result is determined to be verification success information.
[0119] If the verification parameter value to be verified is inconsistent with the target verification parameter value, the verification result is determined to be verification failure information.
[0120] Step S102: when the verification result is verification success information, a collaborative parameter value is generated based on a preset local identity parameter value and a random parameter value.
[0121] If the verification result is verification failure information, the execution is triggered in response to obtaining the collaborative request information broadcast by the target kitchen appliance, and verification is performed based on the target characteristic parameter value, random parameter value and the preset local identity parameter value of the local device in the collaborative request information to obtain the verification result, that is, return to step S101 and re-obtain the collaborative request information of other target kitchen appliances broadcasts.
[0122] The generated collaborative parameter value is also the key parameter value for the communication between the target kitchen appliance and the local machine. Due to the participation of the preset local identity parameter value and the random parameter value, the collaborative parameter value generated each time is different. It not only contains the unique information of the preset local identity parameter value, but also contains the dynamic random parameter value information, avoiding the possibility of repeated generation of collaborative parameter values, ensuring the unique connection between the two communicating parties, and ensuring the security of data transmission.
[0123] Step S103, generating response information associated with the collaborative request information based on the collaborative parameter value, feeding it back to the target kitchen appliance, triggering the target kitchen appliance to verify the collaborative parameter value based on the saved preset local identity parameter value and the random parameter value.
[0124] The target kitchen appliance stores the preset local identity parameter values and random parameter values. The target kitchen appliance applies the preset local identity parameter values and random parameter values to the same algorithm as the local appliance to obtain the collaborative parameter value to be verified. If the collaborative parameter value to be verified is the same as the received collaborative parameter value, a handshake success message including the collaborative parameter value is sent to the local appliance, indicating that the handshake between the target kitchen appliance and the local appliance is successful.
[0125] Step S104, when receiving the handshake success information including the coordination parameter value fed back by the target kitchen appliance in response to the response information, a coordination communication channel with the coordination parameter value as a two-way communication identifier is established with the target kitchen appliance.
[0126] After a collaborative communication channel is established between the target kitchen appliance and this machine, collaborative parameter values are included when control instructions are transmitted between the two parties. After receiving the collaborative parameter values, both parties can execute the sender's control instructions without additional verification, thereby reducing the data authentication process, increasing data processing speed, shortening control response time, and improving user experience.
[0127] In some specific embodiments, when a handshake success message including a collaborative parameter value is received from the target kitchen appliance in response to the response message, a collaborative communication channel with the collaborative parameter value as a two-way communication identifier is established with the target kitchen appliance, including:
[0128] Step S104a, when the power-on time is less than the preset second delay time, when a handshake success message including a collaborative parameter value is received from the target kitchen appliance in response to the response message, a collaborative communication channel with the collaborative parameter value as a two-way communication identifier is established with the target kitchen appliance.
[0129] The preset second delay time is greater than the preset first delay time.
[0130] If the power-on time is greater than or equal to the preset second delay time, and no handshake success information is received from the target kitchen appliance, the pairing is determined to have failed, and the machine stops verifying the subsequent collaborative request information received. This prevents excessive verification processing from occupying a large amount of resources, causing the machine's response delay, and bringing a bad experience to users.
[0131] In response to obtaining the collaborative request information broadcast by the target kitchen appliance, the embodiment of the present application performs verification based on the target characteristic parameter value, random parameter value and the preset local identity parameter value of the local machine in the collaborative request information to obtain a verification result; when the verification result is a successful verification message, a collaborative parameter value is generated based on the preset local identity parameter value and the random parameter value; a response message associated with the collaborative request information is generated based on the collaborative parameter value, and fed back to the target kitchen appliance, triggering the target kitchen appliance to verify the collaborative parameter value based on the saved preset local identity parameter value and the random parameter value; when the handshake success message including the collaborative parameter value fed back by the target kitchen appliance in response to the response message is received, a collaborative communication channel with the collaborative parameter value as a two-way communication identifier is established with the target kitchen appliance. Since the collaborative parameter value contains unique information and dynamic random information, the possibility of repeatedly generating collaborative parameter values is avoided, and the unique connection of the communicating parties can be guaranteed, ensuring the security of data transmission. The collaborative communication channel with the collaborative parameter value as a two-way communication identifier can execute the control instructions of the sender without additional verification during communication, thereby reducing the data authentication process, improving the data processing speed, shortening the control response time, and improving the user experience.
