【Abstract】 In this paper, the TCP/IP stack embedded in digitizers is firstly analyzed, and then the design and implementation of a data-access-middleware is introduced, which provides methods and tools to build communication with the seismometric instruments, and implements tasks such as data receiving, decoding and publishing of all kinds of streams. At last, the middleware is applied in a distributed application software system which is designed to synchronize data with the instruments automatically. It was proved a successful example for the application of the system in the seismometric network of Hebei Province.更多还原
