(2) as shown in fig. 3, the intranet file synchronization module mainly has three parts:
1) bus monitoring task: retrieving the message required by the intranet file synchronization module from the message bus according to the subscription message type of the intranet file synchronization module;
2) and (3) a file chain table to be synchronized: storing a configuration file to be synchronized to an external network, wherein one configuration to be synchronized is a task node, and one task node comprises two attributes: firstly, a file name to be synchronized; secondly, identifying the speed of the file to be synchronized;
3) periodic synchronization thread: periodically inquiring a linked list of files to be synchronized every 100ms, and if the linked list is empty, not performing any processing; and if the linked list is not empty, reading the linked list task nodes, and after one node task is processed and a synchronization success signal is received, continuously processing the next node task.

file attribute: 1: a file name; 2: file data
Frame number: current frame sequence number
And (3) state identification: 1: a first frame; 2: in transmission; 3: last frame
Load length: length of current frame load
Loading: the load consists of two parts, load data and a hash value; the first frame data is a file name to be synchronously configured, and the load is the file name and a file name hash value; the last frame of data is a hash value of the configuration file to be synchronized, the load data is null (all 0), and the hash value is the hash value of the configuration file to be synchronized; in other frames, the load data part is data with configuration files, and the hash value part is empty (all 0);
