In some other implementations of the present embodiment, further comprising: receiving third data sent by a second source node in the multi-split air conditioner, wherein the third data is transmitted by adopting a second communication protocol; converting the third data into fourth data, wherein the fourth data is transmitted by adopting the first communication protocol; and broadcasting and transmitting fourth data to the second target node.
In the normal communication state, the node equipment in the multi-split air conditioner is provided with two paths of communication networks, one path is CAN serial port bus communication and is responsible for receiving communication data sent by other node equipment on the bus, for example, the received wifi data is converted into CAN bus data, and transparent transmission and forwarding are carried out on other nodes on the CAN bus. In addition, the other path is a wifi network, after the network module receives CAN bus data, CAN data are automatically converted into wifi data, and broadcast transmission is carried out on other node equipment in the wifi network, and because the wifi data transmission mode adopts broadcasting, all node equipment in the wifi network CAN receive other node wifi data mutually, and therefore interconnection and intercommunication between wired nodes and wireless nodes in the hybrid network are achieved.
In some examples, after receiving the first data sent by the first source node in the multi-split air conditioner, the method further includes: switching a network module to a transceiver channel, wherein the network module comprises the transceiver channel and a protocol conversion channel; the first data is broadcast through to a third target node using a transceiver channel.
Optionally, converting the first data into the second data includes: switching a network module to a protocol conversion channel, wherein the network module comprises a transceiver channel and a protocol conversion channel; and converting the first data into the second data by adopting a protocol conversion channel.
The network module of the embodiment comprises a transceiver channel and a protocol conversion channel, shares a CAN communication network with the CAN transceiver, and is switched through a switch circuit, namely shares network nodes, so that the number of nodes is reduced, and the transmission reliability CAN be ensured. When the CAN network is used, the communication switch is switched to the transceiver end, and the wireless module is disconnected, so that CAN bus data CAN be directly transmitted at the moment, and the CAN wired network is used. When the wifi network is used, the communication switch is switched to the wireless module, the CAN transceiver switch is disconnected, and the wireless module receives CAN data and directly carries out transparent transmission through the wifi network.
In one implementation of the present embodiment, before converting the first data into the second data, the method further includes: detecting whether a network module accesses a local node, wherein the network module comprises a transceiver channel and a protocol conversion channel; and if the network module is detected to be accessed to the local node, connecting CAN network communication of the local node with the protocol conversion channel.
On the unit, each equipment node detects through the pin level, judges whether there is the network module to be connected to equipment in, if detect there is the network module, CAN network communication switch is connected with the network module automatically, breaks off CAN transceiver communication switch, gets into wifi mode this moment, passes data through wifi network thoroughly. If no network module is detected, the CAN network communication switch is automatically connected with the CAN transceiver module, the network module switch is disconnected, and CAN data is directly forwarded to the bus.
Alternatively, converting the first data into the second data may be, but is not limited to,: if the first data are CAN bus data, aggregating and packaging the CAN bus data to generate second data; and if the first data is wireless data, unpacking and analyzing the wireless data to generate second data.
When the network module sends data through the wifi wireless network, protocol conversion needs to be carried out on the data so as to ensure that CAN and wifi network data are compatible. The network module receives the CAN data and converts the CAN data into wifi network data, and the network module receives the wifi network data and converts the wifi network data into CAN data, so that protocol compatibility CAN be ensured.
In one example, the CAN data is converted into wifi data, the network module receives the CAN bus data, aggregates and packages the data, and broadcasts and sends the data through wifi after the completion. In another example, wifi data is converted into CAN data, the network module receives the wifi data, unpacks and analyzes the data, the analysis is completed and converted into CAN bus data, and broadcast transmission is performed through a CAN bus.

s61, powering up the system;
s62, a mesh module (network module) sends a command for entering networking to corresponding node equipment;
s63, after receiving the command, the corresponding node equipment stops sending data to the CAN bus and waits for the completion of the networking of the wifi-mesh module;
s64, the mesh module finishes networking, and sends a networking finishing broadcast command to the CAN bus;
s65, after the bus corresponds to other node equipment and receives the command, the bus enters a normal communication state;
s66, the wired device normally transmits broadcast data to the bus;
s67, after receiving the bus data, the mesh module converts the bus data into wifi data and sends the wifi data to other node equipment;
and S68, the other node equipment receives wifi data, converts the wifi data into serial data and sends the serial data to the bus.
Because the data transmission mechanisms of the communication modes of the CAN communication and the wifi communication are completely different, protocol conversion needs to be carried out on different network data to correspond to two different transmission protocols to realize data intercommunication, in the embodiment, the protocol conversion is processed by the bottom layer inside the chip through an algorithm, the application layer CAN realize the data intercommunication of the two networks without adding a conversion module, and the protocols are universal. The external machine or the internal machine and the network module share one path of CAN communication, so wifi communication is realized, the protocol adopts a transparent transmission mode, namely, the wifi module which receives CAN bus data is transmitted to the wireless network, and other node equipment receives the wifi data and directly transmits the wifi data to the CAN bus. The network module chip is internally integrated with two functions of CAN communication and wifi communication, CAN enable CAN data and wifi data to be directly communicated through an internal algorithm, does not need to additionally increase data or a protocol converter, and improves the integration level of equipment functions.
