Analysis and Research on data transmission efficiency of distributed measurement and control system

The data of the measurement and control system of each coal mine group are independent. In order to manage the monitoring data of each coal mine, the Coal Industry Group needs to select a suitable data transmission mode to transmit the data of each colliery to the information centre of the group. To meet this requirement, it needs to compare different data transmission modes and choose a stable and efficient data transmission mode. At first, this paper compared the relative merits of different data transmission methods, and then chose three of them to perform experiments. They are File Transfer Protocol, WebServices and database sharing, compare their data transmission efficiency, and finally, select the most appropriate transmission method and apply it to the actual project.
