Optionally, as shown in fig. 7, the control system of the network module further includes: a user interface 58 coupled to the at least one data server 56; the at least one data server 56 is configured to analyze the unit attribute information, and store the analyzed unit attribute information in the database; when a first hypertext transfer protocol (HTTP) request of the user interface 58 is received, reading the analyzed unit attribute information from the database, and sending the analyzed unit attribute information to the user interface 58, so that the user interface 58 displays the analyzed unit attribute information; the first HTTP request is used for acquiring analyzed unit attribute information.

Optionally, as shown in fig. 8, the control system of the network module further includes: a user interface 58 and a parsing client 60 connected to at least one data server 56; at least one data server 56, configured to receive a second HTTP request sent by the parsing client 60; sending the unit attribute information to an analysis client 60, wherein the unit attribute information is analyzed by the analysis client 60, and the analyzed unit attribute information is stored in a database; when receiving a first HTTP request from the user interface 58, the data server 56 reads the parsed unit attribute information from the database, and sends the parsed unit attribute information to the user interface 58, so that the user interface 58 displays the parsed unit attribute information; the first HTTP request is used for acquiring analyzed unit attribute information; and the second HTTP request is used for acquiring the unit attribute information.

In the present embodiment, the number of analysis clients 60 corresponding to each data server 56 may be one or more.

Optionally, at least one data server 56 communicates with at least one access server 54 via a TCP connection, and one data server uniquely corresponds to one access server.

As shown in fig. 7 and 8, a plurality of air conditioning units, that is, units to be finally controlled, exist under each network module 50. The network module 50 firstly requests the address of the access server 54 to which the network module 50 should connect to the scheduling server 52 through a TCP connection (wherein, when the network module 50 is powered on or the existing connection with the access server 54 is disconnected, the network module 50 will connect to the scheduling server 52 first, the connected address and port can be configured through a web page, after connecting to the scheduling server 52, the network module 50 will send a frame of data frame for inquiring the address of the access data server 56, the scheduling server 52 is used for realizing load balancing, after receiving the inquiry data frame of the network module 50, the scheduling server 52 allocates an access server 54 to the network through a load balancing algorithm (for example, Haproxy, which can be configured according to the need of itself), and then the network module 50 disconnects the scheduling server 52, a connection is established with the access server 54. If the address is obtained, the network module 50 disconnects the connection with the scheduling server 52, and the next step is carried out; if the address is not available, a wait period is followed to continue requesting the address from dispatch server 52.

After obtaining the address of the access server 54 connected to the network module 50, the network module 50 establishes a TCP connection with the access server 54, and then sends a login data frame, a binding data frame, and a unit status data frame, where the content of the login data frame includes a unique identifier (MAC address, physical dial, etc.) of the module itself. The acquisition mode of the login data frame is as follows: the network module 50 is an embedded device, and the self program can acquire the information; the login data frame is replied by the access server 54 whether the login is successful, specifically, the data frames are sequentially sent, if the network module 50 sends the login data frame and the access server 54 returns a failure, the network module 50 will send the login data frame again at intervals of 20 seconds, if the login data frame is continuously sent five times and the access server 54 returns a failure, the network module 50 is disconnected from the access server 54, the scheduling server 52 is requested again to obtain a new address of the access server 54, and only the next frame after the login is successful, the binding data frame and the unit state data frame can be sent. The binding data frame includes detailed information of all air conditioning units under the network module 50, and the unit status data frame is acquired by the network module 50 when a certain state of the air conditioning unit itself changes. The binding data frames and the crew status data frames are forwarded by the access server 54 to the data server 56.

The access server 54 communicates with the data server 56 via a TCP connection, and the data server 56 requests the access server 54 to connect in a one-to-one manner. After the connection is established, the access server 54 is allowed to be scheduled. After the network module 50 connects to the access server 54, the access server 54 sends the data frames sent by the network module 50 except the login data frame to the data server 56, and the data server 56 puts the data frames into a cache, and waits for the parsing client 60 to request data for parsing through an Http request.

The parsing client 60 parses the data and stores the parsed data in a database. The status information of all units can be queried in the database, and the user interface 58 (desktop client or website) requests the network interface of the data server 56 in an Http manner, so that the detailed information of the air conditioning units can be displayed and controlled on the user interface 58. Specifically, the data server 56 has a buffer queue, stores data frames sent to the data server 56 by the network module 50 through the access server 54, obtains a frame data through an HTTP request by the parsing client 60, completes parsing according to a predetermined communication protocol, and stores the frame data in the database. All data frames are analyzed by the analysis client 60, and then the result is stored in the database, and the result requested by the client is the data obtained by the data server 56 by reading the database and then returning, or the analysis client 60 is cancelled, and the data is directly analyzed by the data server 56 and stored in the database.

Different users have different control authorities, and only the units under the authority of the users can be checked and controlled in the user interface 58.

When the control command is issued, the user interface 58 selects the object to be controlled and the control operation, and sends the object to the data server 56, and the data server 56 issues the command to the access server 54. The access server 54 determines the object controlled by the control command through the login data frame, and issues the object to the network module 50, and the network module 50 completes the specific control of the control object.

When network module 50 and access server 54 become disconnected due to a network anomaly or other reasons, network module 5072 requests dispatch server 52 again to dispatch a connection to a new access server 54, and the above steps are repeated.

When the access server 54 and the data server 56 are disconnected due to network abnormality or other reasons, the access server 54 actively rejects all the network modules 50 connected to itself, and the network modules 50 request the dispatch server 52 again to perform the above steps. The access server 54 waits for the data server 56 to reconnect and the access server 54 is found by the network module 50 through the dispatch server 52 only if the data server 56 and the access server 54 are properly connected. I.e., the network module 50 will only log into the access server 54 where the entire link is normal.

Through the steps, the rapid and accurate centralized control and real-time state monitoring of the multi-system air conditioning unit are completed.
