[0028] In the technical solution, the step of determining the first mapping relationship according to the preset communication protocol includes: first obtaining the first data information of the heat pump device, wherein the first data information may be the parameter address, parameter name, and parameter meaning of the heat pump device, and since the first data information is internal to the heat pump device, the preset communication protocol in the heat pump device is associated with the first data information. Then obtain the second data information corresponding to the target communication protocol, that is, obtain the second data information set by the target communication protocol, wherein the second data information may be the parameter address, parameter name, and parameter meaning. Then determine the second mapping relationship according to the first data information and the second data information, that is, extract the same type of data from the first data information and the second data information, and determine the conversion relationship between the two, that is, the second mapping relationship. For example, if the address of a parameter in the first data information is A, and the address of the same parameter in the second data information is B, then the mapping relationship between A and B is used as the second mapping relationship between the first data information and the second data information. Finally, the first mapping relationship corresponding to the first protocol signal is determined in the second mapping relationship according to the first protocol signal. Since the data in the first protocol signal is composed of part of the data in the first data information, the data mapping relationship related to the data in the first protocol signal can be selected in the second mapping relationship according to the data in the first protocol signal, and the data mapping relationship is used as the first mapping relationship.

[0030] In the technical solution, the first data information includes: one or several combinations of parameter address, parameter name and parameter meaning. And the second data information also includes one or several combinations of parameter address, parameter name and parameter meaning.

Since the configuration component 110 is connected to the conversion component 106 in communication, the configuration component 110 can also send the processed data information to the conversion component 106, so that the conversion component 106 can convert the first protocol signal and the second protocol signal based on the data information of the heat pump device. The present invention realizes the acquisition and processing of the data information of the heat pump device 20 by setting the configuration component 110, and provides a basis for converting the first protocol signal of the heat pump device 20 into the second protocol signal later.

[0069] In some embodiments, optionally, the configuration component 110 includes: an interactive component 1102, the interactive component 1102 is used to input data information of the heat pump device; a first processor 1104, the first processor 1104 is connected to the interactive component 1102, and generates a mapping relationship between the target communication protocol and the preset communication protocol based on the data information of the heat pump device 20; a second processor 1106, the second processor 1106 is connected to the first processor 1104, and is used to convert the mapping relationship and generate a data signal corresponding to the mapping relationship; a driving component 1108, the first end of the driving component 1108 is connected to the second processor 1106, and the second end of the driving component 1108 is connected to the conversion component 106, and is used to send the data signal corresponding to the mapping relationship to the conversion component 106.

[0070] In this embodiment, the configuration component 110 may include an interactive component 1102, a first processor 1104, a second processor 1106, and a drive component 1108. Among them, the interactive component 1102 can interact with the user, that is, the user can input the data information of the heat pump device into the configuration component 110 through the interactive component 1102. Exemplarily, the interactive component 1102 can be a touch screen or a button. The interactive component 1102 is connected to one end of the first processor 1104, and then the data information of the heat pump device 20 is input into the first processor 1104. The first processor 1104 can generate a mapping relationship between the target communication protocol and the preset communication protocol for the data information of the heat pump device, and the second protocol signal is a protocol signal generated based on the target communication protocol. The other end of the first processor 1104 is connected to the second processor 1106, so that the mapping relationship is input into the second processor 1106. The second processor 1106 can process the mapping relationship and convert the mapping relationship into a data signal, thereby realizing the transmission of the mapping relationship to the conversion component 106. The first end of the driving component 1108 is connected to the second processor 1106, and the second end of the driving component 1108 is connected to the conversion component 106.

Therefore, it is necessary to define a mapping module parameter table, the address starts from 1, and address 5 is defined as the wind speed setting parameter, and the value means 1-low wind speed, 2-medium wind speed, 3-high wind speed, and 4-automatic. The set wind speed address 3 of the first brand heat pump device 20 is mapped to the module parameter table address 5, and the set wind speed address 6 of the second brand heat pump device 20 is mapped to the module parameter table address 5. Then, the data acquired by the interactive component 1102 and the third processor 1064 are collected, so that the mapping relationship between the target communication protocol and the preset communication protocol can be generated.

[0087] Step 702: Acquire a first protocol signal;

[0088] Step 704: Determine a preset communication protocol corresponding to the first protocol signal according to the first protocol signal;

[0089] Step 706: determining a first mapping relationship according to the preset communication protocol, where the first mapping relationship is a mapping relationship between the preset communication protocol and the target communication protocol;

[0090] Step 708: Determine a second protocol signal according to the first mapping relationship and the first protocol signal, wherein the second protocol signal corresponds to the target communication protocol.

[0091] The present invention provides a control method for a protocol conversion device, which is mainly used for the protocol conversion device in any of the above technical solutions, wherein the control method for the protocol conversion device mainly includes: firstly obtaining a first protocol signal of a plurality of heat pump devices connected to at least two downlink communication components, wherein the number of the first protocol signals can be multiple, and since the heat pump device matches the preset communication protocol, the first protocol signal also matches the preset communication protocol. Then, according to the first protocol signal, a preset communication protocol matching the first protocol signal is determined, that is, a preset communication protocol in the heat pump device connected to the protocol conversion device. Then, according to the preset communication protocol, a first mapping relationship is determined, the first mapping relationship refers to a mapping relationship between a preset communication protocol and a target communication protocol. Before the protocol conversion device starts working, a mapping relationship data set is pre-stored in the protocol conversion device, and the mapping relationship data set includes a plurality of different mapping relationships between preset communication protocols and target communication protocols, wherein the preset communication protocol refers to the communication protocol before conversion, and the target communication protocol refers to the communication protocol after conversion. After obtaining the first mapping relationship, the first protocol signal is converted according to the first protocol signal and the first mapping relationship to obtain a second protocol signal, wherein the second protocol signal matches the target communication protocol. The present invention first sets a mapping relationship between multiple different preset communication protocols and a target communication protocol inside a protocol conversion device, then obtains a first protocol signal sent by a heat pump device through a downlink communication component, and then determines a first mapping relationship according to a preset communication protocol matching the first protocol signal, and finally converts the first protocol signal according to the first mapping relationship to obtain a second protocol signal, thereby realizing the conversion of data of multiple heat pump devices without a unified communication protocol into data of a unified communication protocol, and then uploading them to the same platform for unified scheduling by the platform.

[0096] Step 808: Determine a first mapping relationship corresponding to the first protocol signal in the second mapping relationship according to the first protocol signal.

[0097] In this embodiment, the step of determining the first mapping relationship according to the preset communication protocol includes: first obtaining the first data information of the heat pump device, wherein the first data information may be the parameter address, parameter name, and parameter meaning of the heat pump device, and since the first data information is internal to the heat pump device, the preset communication protocol in the heat pump device is associated with the first data information. Then obtain the second data information corresponding to the target communication protocol, that is, obtain the second data information set by the target communication protocol, wherein the second data information may be the parameter address, parameter name, and parameter meaning. Then determine the second mapping relationship according to the first data information and the second data information, that is, extract the same type of data from the first data information and the second data information, and determine the conversion relationship between the two, that is, the second mapping relationship. For example, if the address of a parameter in the first data information is A, and the address of the same parameter in the second data information is B, then the mapping relationship between A and B is used as the second mapping relationship between the first data information and the second data information. Finally, the first mapping relationship corresponding to the first protocol signal is determined in the second mapping relationship according to the first protocol signal. Since the data in the first protocol signal is composed of part of the data in the first data information, the data mapping relationship related to the data in the first protocol signal can be selected in the second mapping relationship according to the data in the first protocol signal, and the data mapping relationship is used as the first mapping relationship. The present invention provides a basis for converting the first protocol signal into the second protocol signal by determining the mapping relationship according to the first data information of the heat pump device and the second data information corresponding to the target communication protocol.
