and after the network communication quality grade is matched every time, clearing the number of self-sent data sent by other equipment nodes and actually received by each internal equipment node in the network.
In some embodiments, the network communication method of the multi-split air conditioning system specifically includes:
step 1: the method comprises the steps that a unit is electrified, all equipment is waited for network access connection, normal communication is started, and all node equipment data sending modes are communicated with each other through transparent broadcast at the moment;
step 2: after all the devices are determined to be on-line, the host (the external machine) sends a counting and clearing broadcast command to all the sub-nodes (the internal machines) of the wifi-mesh network;
and step 3: after receiving the clearing command, the child nodes clear the self statistical counting, namely the number of the sent data, receive the number of the data and restart the counting;
and 4, step 4: counting the number X of self-sent data in real time, sending other node equipment in a broadcasting mode, and receiving statistical data Xn of the number of the sent data sent by other node equipment;
and 5: counting the actual data number M of other node equipment in the wifi-mesh network received by the current equipment node in real time, and calculating the data transmission success rate of the current equipment node at the moment
P＝M/(X1+X2+……Xn)*100％；
Step 6: all the node devices count and calculate the data receiving success rate in real time according to the mode and send the calculated data to the host device.
And 7: the host equipment performs quantitative average processing when receiving communication success rate data sent by other child equipment, namely receiving average Pv (P1+ P2+ … Pn)/N of the success rate data of all other child node equipment;
and 8: quantitative comparison is carried out, and the communication quality of the wifi-mesh network of the system is divided into a plurality of grades according to actual conditions and applications, such as 1, 2, … … X. 1 represents a normal communication quality network, all communication time sequences, data sending modes and the number are unchanged, and a host periodically sends a counting clearing broadcast command sent by all child nodes (the counting quantity is prevented from being overlarge and the counting overflow is prevented);
and step 9: the step is communication data optimization adjustment, and due to the fact that wifi signals are interfered or when the signals are weakened, wifi transmission capacity is limited, and at the moment, large-load data transmission can cause certain packet loss rate. Therefore, when the communication quality becomes 2,3 … … X, the instability of the wifi network signal is shown. At the moment, redundancy removal processing needs to be carried out on the communication data of the unit, partial state data of the unit is reduced, and a unicast sending mode is adopted for control data to ensure the reliable operation of the unit. The larger the grade is, the worse the network communication quality is, at this time, the data transmission frequency is reduced to meet the system reliability requirement, for example, grade 2, the data transmission frequency is reduced, grade 3, the data transmission frequency is reduced again, grade 4, the data transmission frequency is reduced on the basis of the transmission frequency of grade 3, the control data is set to be unicast communication, the unicast communication refers to that a handshake mechanism is made for the specific important control data to ensure the reception reliability, the output transmission is controlled to be one-to-one, and other nodes do not receive the data;
step 10: and synchronously issuing all the child nodes to send a counting clearing broadcast command, restarting counting, indicating that the communication signal is recovered to be normal when the communication quality is changed to be excellent, recovering the communication time sequence to be normal at the moment, synchronously issuing the counting broadcast command, restarting the counting technology, and performing adjustment at all times as the above cycle.
Usually, wifi-mesh multi-split network data is sent in a transparent transmission broadcasting mode, all node devices can acquire data related to other node devices, but when wifi signal transmission is weak or is interfered, communication is poor, partial communication data are lost, and great influence is caused on unit operation.
In the embodiment, in an application layer of a multi-split wifi-mesh network, each node device counts the number of data sent and received by the node device to calculate the success rate of the current node data, and the system dynamically adjusts the data sending time sequence according to different success rates to meet the reliable communication requirements of units.
