Specifically, the data point numbers (one data point number corresponds to one measuring point) under each station are divided into different groups, and meanwhile, the data point numbers under the stations between the groups are redundant and repeated, and the data group numbers correspond to each measuring point group.
As shown in fig. 2, fig. 2 illustrates a principle of performing inter-group data redundancy grouping processing on a data point number in units of a station, wherein a group number 1 includes a station 1, a station 2, and a station 3, the group number 2 includes the station 3, the station 4, and the station 5, and the group number 3 includes the station 4, the station 5, and the station 6.

Meanwhile, each channel and the receiving end system independently establish network communication, so that the parallel operation of the channels is ensured, and under normal conditions, each channel transmits data of specific packets without influencing each other, and the transmission efficiency can be improved.
