Specifically, the data transmission device may obtain air conditioner data to be transmitted, where the air conditioner data may be sent by an air conditioner or sent by a server, and then may extract data characteristics of the air conditioner data, select a communication protocol (the communication protocol may include, but is not limited to, an RS485 communication protocol, a CAN communication protocol, and an IO-LINK communication protocol) matching the data characteristics from among a plurality of communication protocols pre-configured by the data transmission device according to the data characteristics, and then may transmit the air conditioner data between the server and the air conditioner based on the communication protocol. The number of the air conditioners can be multiple, and the server can be realized by an independent server or a server cluster formed by multiple servers.
In an embodiment, a method for transmitting air-conditioning data is provided, and referring to fig. 2, fig. 2 is a flowchart illustrating a method for transmitting air-conditioning data in an embodiment, which may be implemented by the data transmission apparatus shown in fig. 1, and the method for transmitting air-conditioning data may include the following steps:
and step S101, acquiring air conditioner data to be transmitted.
The step is mainly that the data transmission device can acquire the air conditioner data to be transmitted, and the air conditioner data can be data sent to the air conditioner mainboard by the server or data sent to the server by the air conditioner mainboard. The air conditioner data may include data carrying operating state information of the air conditioner, or may be data such as a related instruction used by the server to control the air conditioner.
Specifically, the server can send a temperature adjustment instruction to the air conditioner mainboard, so that the temperature of the air conditioner is adjusted to a set value, and at the moment, the data transmission device can acquire the temperature adjustment instruction as air conditioner data to be transmitted to the air conditioner mainboard; the air conditioner mainboard can also send the real-time operating data of the air conditioner to the server as the real-time temperature, and the data transmission device can acquire the real-time temperature as the air conditioner data to be transmitted to the server.
And step S102, extracting data characteristics of the air conditioner data.
In this step, the data transmission device may extract the data characteristics of the air-conditioning data after acquiring the air-conditioning data, where the data characteristics may include characteristic information of data such as a data frame format and a check bit, and may also use the air-conditioning data itself as the data characteristics. Because various communication protocols generally stipulate that data are transmitted in data characteristics such as specific data frame formats and check bits, under the specific communication protocols, the server and the air conditioner main board can package the air conditioner data to be transmitted based on the specific data frame formats, the check bits and the like, so that the air conditioner data to be transmitted have data characteristics matched with the specific data frame formats or the check bits, and the step extracts the data characteristics of the air conditioner data so as to determine the communication protocol for transmitting the air conditioner data based on the data characteristics.
Step S103, selecting a communication protocol matched with the data characteristics from a plurality of communication protocols configured in advance.
The step is mainly that after the data transmission device extracts the data features of the air conditioner data, a communication protocol matched with the data features CAN be selected from a plurality of pre-configured communication protocols, wherein the communication protocol CAN be pre-configured in a corresponding communication chip, for example, the communication protocol CAN include but is not limited to an RS485 communication protocol, a CAN communication protocol and the like, the pre-configuration of the RS485 communication protocol and the CAN communication protocol CAN be realized by installing the RS485 communication chip and the CAN communication chip in the data transmission device, and then the communication protocol matched with the data features CAN be selected from the communication chip. The communication protocols and the corresponding communication chips configured by the data transmission device can be increased according to actual data transmission requirements, that is, the data transmission device can be compatible with more communication protocols according to actual requirements, so as to increase the applicability of the data transmission device under various communication protocols.
Specifically, assuming that the data characteristic a of the air conditioner data matches the communication protocol a, and the data transmission device is pre-configured with the communication protocol a, the communication protocol B, and the communication protocol C, after the data transmission device receives the air conditioner data and obtains the data characteristic a of the air conditioner data, the communication protocol a may be selected from the communication protocol a, the communication protocol B, and the communication protocol C as a communication protocol matching the data characteristic a.
And step S104, transmitting the air conditioner data based on the communication protocol.
The communication chip configured with the communication protocol can be used for realizing the transmission of air conditioner data. For example, the data transmission device may be configured with a communication chip a matching the communication protocol a and a communication chip B matching the communication protocol B, and then in this step, after the data transmission device selects the communication protocol a as the communication protocol matching the data characteristics of the air-conditioning data, the data transmission device may implement transmission of the air-conditioning data between the server and the air-conditioning motherboard based on the communication chip a, because the air-conditioning data can be accurately analyzed only by the communication protocol matching the data, and if the air-conditioning data is transmitted by the communication protocol not matching the data, the accurate data cannot be identified and a data scrambling code cannot be generated, which results in that effective data transmission cannot be performed between the server and the air-conditioning motherboard.
According to the method for transmitting the air conditioner data, the air conditioner data to be transmitted are obtained, the data characteristics of the air conditioner data are extracted, the communication protocol matched with the data characteristics is selected from a plurality of pre-configured communication protocols according to the data characteristics, then the air conditioner data are transmitted based on the communication protocol, the corresponding communication protocol can be selected according to the data characteristics of the air conditioner data to be transmitted, the flexibility of transmitting the air conditioner data is improved, and when the data characteristics of the air conditioner data change, the air conditioner data can be flexibly switched to the corresponding communication protocol for transmission.
In one embodiment, the step of extracting the data feature of the air-conditioning data may include:

Each communication chip is configured with different communication protocols, that is, the data transmission device may be provided with a communication chip a, a communication chip B and a communication chip C, wherein the communication chip a is configured with the communication protocol a, the communication chip B is configured with the communication protocol B and the communication chip C is configured with the communication protocol C.
The data transmission device can receive and analyze the air conditioner data through each communication chip respectively, obtain the analysis result of each communication chip, and then obtain the data characteristics of the air conditioner data according to the analysis result. Specifically, referring to fig. 3, fig. 3 is a schematic diagram of a circuit for transmitting air conditioner data in an embodiment, where the data transmission device may be implemented by a processor, a CAN communication chip and an RS485 communication chip, where the processor is respectively in communication connection with the CAN communication chip and the RS485 communication chip, and is connected to a communication interface of an air conditioner motherboard by the CAN communication chip and the RS485 communication chip, so that the data transmission device CAN obtain air conditioner data sent by the air conditioner motherboard through the communication interface of the air conditioner motherboard, where the processor CAN receive and analyze the air conditioner data sent by the air conditioner motherboard through the CAN communication chip and the RS485 communication chip, the CAN communication chip and the RS485 communication chip CAN respectively analyze an analysis result carrying information such as a data frame format, a check bit, and the like of the air conditioner data, and then the processor CAN obtain the analysis result and extract a data frame format, a data format, a check bit, and the like of the air, Check bits and the like.
In the embodiment, the air conditioner data to be transmitted are analyzed through the plurality of communication chips, so that the data characteristics of the air conditioner data can be accurately acquired based on the analysis result of each communication chip, and an accurate data basis is provided for subsequently determining the communication protocol matched with the data characteristics.
In one embodiment, the step of selecting a communication protocol matching the data characteristics from a plurality of preconfigured communication protocols may include:
acquiring standard data characteristics corresponding to each communication protocol; comparing the data characteristic to a standard data characteristic; and determining a communication protocol matched with the data characteristics according to the comparison result.
In this embodiment, the data transmission device may obtain standard data characteristics corresponding to each communication protocol after determining the data characteristics of the air-conditioning data, compare the data characteristics with the standard data characteristics, and determine a communication protocol matching the data characteristics of the air-conditioning data according to the comparison result, so as to transmit the air-conditioning data based on the communication protocol.
Each communication protocol configured on the data transmission device generally has specific standard data characteristics (such as a standard data frame format, check bits, and the like), so that after the data characteristics of the air conditioner data to be transmitted are obtained, the data characteristics can be compared with the specific standard data characteristics of each communication protocol, and if the data characteristics are the same as the standard data characteristics specified by a certain communication protocol, it can be determined that the communication protocol is the communication protocol matched with the data characteristics. And under the condition that a plurality of communication chips are configured, each communication chip is respectively and previously configured with a corresponding communication protocol, so that whether the data characteristics of the air-conditioning data are compared with the standard data characteristics or not can be judged through the plurality of communication chips, and if the comparison is matched, the communication chip matched with the data characteristics can be adopted to realize the selection of the communication protocols.
Specifically, referring to fig. 3, after the CAN communication chip and the RS485 communication chip analyze the air-conditioning data to obtain the data characteristics of the air-conditioning data, assuming that the data characteristics of the obtained air-conditioning data are "data frame format 1010", assuming that the standard data frame format of the CAN communication chip is "1010", and the standard data frame format of the RS485 communication chip is "1110", the data frame format of the air-conditioning data and the standard data frame format of the CAN may be compared by the CAN communication chip, comparing the data frame format of the air-conditioning data and the standard data frame format of the RS485 by the RS485 communication chip, after comparing the data frame formats of the CAN communication chip and the standard data frame format of the RS485 communication chip, the corresponding comparison result may be sent to the processor, and then the processor may determine that the data characteristics of the air-conditioning data match the communication protocol of the CAN communication chip, i.e. the CAN communication protocol, therefore, air conditioner data transmission between the air conditioner mainboard and the server CAN be realized based on the CAN communication chip.
The communication protocol matched with the data characteristics of the air conditioner data can be efficiently and accurately determined based on the standard data characteristics of each communication protocol, the efficiency and the accuracy of air conditioner data transmission are improved, a plurality of communication protocols can be compatible, and the applicability of transmission of the air conditioner data under the plurality of communication protocols is improved.
