The Precursor Observation Network of China has experienced three main stages:analogue observation stage,ninth "Five Year Plan" digital stage and tenth "Five Year Plan" network stage.Each stage has a different observation system,and this increases the complexity of the running of the Precursor Observation Network.From 2010,CEA decided to integrate these different observation systems.The main content of this integration includes instrument and computer network transforming in stations,software upgrading,and migration of historical precursor observation data into the current database system in order to reach a uniform platform of data collection,storage,exchange,management and service.This paper analyses the status and main problems of the Precursor Observation Network before integration and introduces the main content and technical key points of integration and the results achieved.%我国地震前兆台网先后经历了“模拟和人工”、“九五”数字化、“十五”网络化等3个阶段,目前并行运转着“模拟和人工”、“九五”、“十五”等3套观测系统,这增大了前兆台网运行维护工作的复杂性.2010年起开始实施的前兆台网改造升级工作,将“九五”、“模拟和人工”观测系统整体并入了“十五”系统.其主要工作内容包括台站接入改造、前兆专业软件升级和并网仪器历史数据的迁移等几个方面,以实现前兆台网3套观测系统统一的运行监控、数据采集、存储、交换、管理和服务.本文系统分析了前兆台网观测系统的现状和存在的问题,介绍了观测系统整合的主要工作内容、技术关键点、取得的成果和效益等.
