摘　　要：分析几种地震数据采集器网络协议和数据格式,设计一种仪器数据访问中间件,为实现上位机应用程序与数采网络通信、多种数据流接收和发布,提供方法和工具。利用中间件开发测震仪器数据自动同步软件,实现地震台站参数和仪器健康状态的自动同步,在河北测震台网的成功应用证明了中间件的实用性。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.
