[0030] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0031] In order to reduce the difficulty of encryption and decryption of serial communication, the air conditioner of the embodiment of the present invention does not add dynamic keys, and sends key setting instructions through the mobile terminal to control the air conditioner to enter the key setting state. In the key setting state, the mobile terminal sends first key information to the controller through the server and the communication module, and sends remote control information related to the first key information to the controller through the air conditioner remote control. The controller determines the second key information according to the remote control information, synchronizes the first key information and the second key information, and sets the key of the air conditioner according to the synchronization result, which simplifies the key generation process, reduces the risk of key storage and maintenance, and further encrypts on the basis of the preset key of the wired serial communication, thereby improving the encryption level and increasing the security of communication.

[0032] Combine the following Figure 1-Figure 6 The air conditioner according to the embodiment of the present invention is described as follows. Figure 1 As shown, the air conditioner 1 of the embodiment of the present invention comprises: a communication module 13 and a controller 14, wherein:

[0033] like Figure 2 FIG. 1 is a schematic diagram of a key setting method for an air conditioner according to an embodiment of the present invention. Figure 2 It can be seen that the communication module 13 communicates with the mobile terminal 11 through the server 12, and is used to control the communication between the mobile terminal 11 and the air conditioner 1; the controller 14 is used to receive the key setting instruction issued by the mobile terminal 11 through the server 12 and the communication module 13, so as to control the air conditioner 1 to enter the key setting state; in the key setting state, the remote control information corresponding to the first key information issued by the mobile terminal 11 and sent by the air conditioner remote controller 15 is received; the second key information is determined according to the remote control information; the first key information and the second key information are synchronized, and the key of the air conditioner 1 is set according to the synchronization result.

[0034] In the embodiment, the air conditioner 1 establishes a normal network connection with the server 12, the mobile terminal 11 such as a mobile phone APP (application, mobile phone software) and the communication module 13. In the above network connection relationship, the key information can be transmitted by mutual communication. In order to increase the security of the above communication, the preset key between the communication module 13 and the controller 14 can be encrypted again, and the encryption process is completed through user settings.

[0035] For example, when a user customizes a key, he opens the mobile terminal 11, such as a mobile phone APP, enters the user key setting interface, and enters the icon content in the user setting interface, such as operating the refrigeration icon, stroke icon, and temperature icon, etc. After the operation of the icon is completed, press the confirmation button and send the current icon content.

[0036] The mobile terminal 11 generates the first key information according to the received icon content, for example, receives the key information corresponding to the icon content. For example, after the mobile terminal 11 receives the refrigeration icon, the stroke icon and the temperature icon, it generates the first key information according to the refrigeration icon, the stroke icon and the temperature icon, for example, generates digital key information, that is, 23456789 is the first key information.

[0037] After generating the first key information, the mobile terminal 11 sends the first key information and the key setting instruction to the server 12, the server 12 sends the first key information and the key setting instruction to the communication module 13, the communication module 13 sends the first key information and the key setting instruction to the controller 14, and the controller 14 stores the received first key information.

[0038] The key setting instruction is sent by the communication module 13 to the controller 14, such as the air conditioning control MCU (Microcontroller Unit). After receiving the key setting instruction, the controller 14 controls the air conditioner 1 to enter the key setting state. When the air conditioner is in the key setting state, the user inputs the icon content in the user setting interface and operates the air conditioning remote controller 15 to send remote control information corresponding to the first key information. For example, when the first key information is the key information corresponding to the cooling icon, the corresponding remote control information is cooling; when the first key information is the key information corresponding to the stroke icon, the corresponding remote control information is stroke; when the first key information is the key information corresponding to the temperature icon, the corresponding remote control information is temperature, such as 26°C. After receiving the remote control information, the controller 14 parses the remote control information and generates the second key information, such as converting cooling, stroke and 26°C into digital key information such as 12345678.

[0039] The controller 14 synchronizes the generated second key information with the first key information, and when the synchronization is completed, determines that the user's key setting is completed.

[0040] According to the air conditioner 1 of the embodiment of the present invention, when the user sets the key of the air conditioner, the air conditioner 1 is controlled to enter the key setting state by receiving the key setting instruction sent by the mobile terminal 11, and in the key setting state, the key is set based on the communication between the communication module 13 and the controller 14, so that the user can customize the key of the air conditioner, simplifying the key generation process, and further encryption is performed on the basis of the preset key of the wired serial port communication, thereby improving the encryption level and increasing the security of communication.

[0041] In some embodiments, when controlling the air conditioner 1 to enter the key setting state, the controller 14 is configured to: send a reminder message of entering the key setting state to remind the user that the air conditioner 1 enters the key setting state.

[0042] In the embodiment, after receiving the key setting command, the controller 14, such as the air conditioner control MCU, controls the air conditioner 1 to enter the user key setting state. At this time, a reminder message is issued to remind the user that the air conditioner 1 enters the key setting state, such as the indicator light is on, and it is considered that the air conditioner 1 has entered the key setting state. By issuing a reminder message when the air conditioner 1 enters the key setting state to remind the user that the air conditioner 1 enters the key setting state, the user can be reminded to complete the key setting within the set time, avoiding the key setting failure caused by not performing the key setting for too long, thereby facilitating the user to perform the key setting according to the reminder message.

[0043] In some embodiments, when controlling the air conditioner 1 to enter the key setting state, the controller 14 is further configured to: time the duration of the air conditioner 1 entering the key setting state, and when the duration exceeds a first preset duration, control the air conditioner 1 to exit the key setting state.

[0044] In the embodiment, after receiving the key setting command, the controller 14, such as the air conditioner control MCU, controls the air conditioner 1 to enter the user key setting state. At this time, the controller 14 starts to count the time that the air conditioner 1 enters the user key setting state. When the time that the air conditioner 1 enters the user key setting state does not reach the first preset time, the controller 14 controls the air conditioner 1 to maintain the key setting state until the time that the air conditioner 1 enters the user key setting state exceeds the first preset time, it is considered that the air conditioner 1 has timed out from entering the key setting state, and after the timeout, the controller controls the air conditioner to exit the key setting state. By counting the time that the air conditioner 1 enters the key setting state, it is avoided that the air conditioner 1 is in this state for a long time, which causes the user to make an erroneous operation, thereby improving the experience.

[0045] For example, the first estimated duration is recorded as t1, t1=15s. When the time when the air conditioner 1 enters the user key setting state exceeds the first estimated duration, that is, when the time when the air conditioner 1 enters the user key setting state exceeds 15s, the air conditioner is controlled to exit the key setting state to avoid the air conditioner 1 being in the key setting state for a long time, so as to facilitate the normal control of the subsequent cooling and temperature adjustment of the air conditioner.

[0046] In some embodiments, when the first key information and the second key information are synchronized and the key of the air conditioner 1 is set according to the synchronization result, the controller 14 is configured to: determine whether the first key information and the second key information match; if the first key information and the second key information match, determine that the key setting is successful; if the first key information and the second key information do not match, determine that the key setting fails.

[0047] In an embodiment, Figure 3 FIG. 1 is a schematic diagram of a key setting method for an air conditioner according to an embodiment of the present invention. Figure 3 It can be seen that the first key information and the second key information are synchronized by an algorithm in the controller 14. The first key information is for example a mobile phone icon key, and the second key information is for example a user key generated by the air conditioner. When the mobile phone icon key and the user key generated by the air conditioner are synchronized, it is determined whether the two match. When it is determined that the first key information and the second key information match, it is considered that the key setting of the air conditioner 1 is successful; when it is determined that the first key information and the second key information do not match, it is considered that the key setting of the air conditioner 1 has failed. The key synchronization judgment is realized by judging whether the first key information and the second key information match.

[0048] For example, the mobile terminal 11 is a mobile phone APP, the first key information is 23456789, and the second key information is 12345678. The first key information 23456789 and the second key information 12345678 are synchronized by an algorithm in the controller 14, that is, when 23456789-11111111 is synchronized successfully, and after the synchronization is successful, it is determined that the key setting of the air conditioner 1 is completed.

[0049] In some embodiments, when synchronizing the first key information and the second key information, the controller 14 is further configured to: time the synchronization duration of the first key information and the second key information, and determine that the key setting fails when the synchronization duration exceeds a second preset duration threshold.

[0050] In the embodiment, when the controller 14 synchronizes the first key information and the second key information, the controller 14 starts timing the synchronization duration of the first key information and the second key information, and when the synchronization duration of the first key information and the second key information does not reach the second preset duration, the controller 14 continues to synchronize the first key information and the second key information, until the synchronization duration of the first key information and the second key information exceeds the second preset duration, it is considered that the key setting of the air conditioner 1 has failed, and it is inquired whether to reset the key of the air conditioner 1, until the air conditioner 1 exits the key setting state. By timing the synchronization duration of the air conditioner 1, it is possible to avoid the synchronization time being too long and reducing the user experience, and when the synchronization times out, the mobile terminal notifies the user that the key setting of the air conditioner has failed, and inquires the user whether to reset the key of the air conditioner 1, so that the user can make selective settings according to current needs.

[0051] In some embodiments, after determining that the key setting fails, the controller 14 is further configured to: issue a reminder message that the password setting fails.

[0052] In an embodiment, when the first key information and the second key information are synchronized, if the synchronization of the first key information and the second key information fails, a reminder message is issued to remind the user that the key setting of the air conditioner 1 has failed. After the key setting fails, a reminder message is issued to inform the user of the key setting result in time, so that the user can perform subsequent control according to the key setting result.

[0053] In some embodiments, when determining the second key information based on the remote control information, the controller 14 is configured to: determine the graphic information corresponding to the first key information; determine the remote control information corresponding to the graphic information based on the graphic information; determine the second key information based on the remote control information, wherein a plurality of sets of correspondence relationships between different remote control information and the second key information are pre-stored in the controller 14.

[0054] In an embodiment, Figure 4 FIG. 1 is a schematic diagram of a key setting method for an air conditioner according to an embodiment of the present invention. Figure 4 It can be seen that after the controller 14 receives the key setting instruction, it controls the air conditioner 1 to enter the key setting state. The controller 14 receives the remote control information corresponding to the first key information sent by the mobile terminal 11 and sends it from the air conditioner remote controller 15, and parses the content of the remote control information. According to the correspondence relationship set between multiple groups of different remote control information and the second key information pre-stored in the controller 14, the remote control information is converted into the second key information through an algorithm, for example, the air conditioner generates a user key.

[0055] For example, when determining the second key information, the air conditioner remote controller 15 is operated to send remote control information, such as transmitting a related radio frequency signal through the air conditioner remote controller 15. When the first key information is generated by parsing the cooling icon, the air conditioner remote controller 15 is operated to send cooling remote control information corresponding to the cooling icon. The controller 14 parses the received cooling remote control information to convert the cooling remote control information into the second key information. The second key information is generated by operating the remote control information corresponding to the icon of the first key information sent by the air conditioner remote controller 15.

[0056] In some embodiments, after determining that the password is set successfully, the communication module 13 is further used to: store the first key information.

[0057] In an embodiment, Figure 5 FIG. 1 is a schematic diagram of a key setting method for an air conditioner according to an embodiment of the present invention. Figure 5 It can be known that the controller 14 synchronizes the first key information and the second key information, for example, synchronizes the mobile phone icon key with the user key generated by the air conditioner. When it is determined that the first key information and the second key information are synchronized successfully, it is determined that the key setting of the air conditioner 1 is successful. After the key setting of the air conditioner 1 is successful, the first key information temporarily stored in the controller 14, namely the mobile phone icon key, is transmitted to the communication module 13 and stored as the official key.

[0058] In some embodiments, after determining that the password is set successfully, the controller 14 is further configured to: store the second key information.

[0059] In an embodiment, Figure 5 As shown, the controller 14 synchronizes the first key information and the second key information, for example, after synchronizing the mobile phone icon key with the air conditioner generated user key, when it is determined that the first key information and the second key information are synchronized successfully, it is determined that the key setting of the air conditioner 1 is successful. After the key setting of the air conditioner 1 is successful, the second key information, i.e., the air conditioner generated user key, is stored in the controller 14.
