Abstract:

In seafloor observatory networks, sampling data of each instrument are sent to their own upper computer respectively, which then summarizes all the data and sents them to the data management system server. On the basis of a comprehensive evaluation of data sampling format, data transforming velocity and data transforming capacity, we design a communication protocol between the upper computer and the data server. Package head, package body and cyclic redundancy check (CRC) are included in the communication package. For different upper computers, the format of package head is the same while the format of package body is designed respectively according to the specific characters of the instruments. Besides, we also develop a corresponding client and server software according to the communication protocol. Test results show that the proposed communications protocol can secure full, correct and efficient data transmission from the upper computer to the data sever.
