摘　　要：为在一定程度上缓解新疆地震前兆观测中存在的仪器备机备件不足、观测资料异常排除困难等问题,新疆地震局自主研制了EAXJEQ-I通用型地震前兆数据采集器,这款数据采集器具有丰富的外部接口和良好的可扩展性能,裸机最大相对误差为0.05%,拥有2G数据存储空间,性能指标符合相关规定,与中国地震前兆台网管理系统之间具备良好的兼容性,利用配套的上位机软件可对数据采集器的各项参数进行灵活设置。目前这款数据采集器已经兼容多种传感器,在连续3年的观测中,该型数据采集器性能稳定,取得了实际应用效果。围绕EAXJEQ-I型通用地震前兆数据采集器,分类列举了各种主要性能参数指标,详细说明了外部接口,简单介绍了使用方式和目前已有的应用情况等。With regard to solve the problem of inefficiency of earthquake precursor observation devices and abnormal data,Earthquake Administration of Xinjiang Uygur Autonomous Region designed EAXJEQ-I earthquake precursor data collector all by itself.This collector has abundant of external panels and good qualities with an error of 0.05%,which posses an saving space of 2G in accordance of the related rules.Installed many kinds of sensors,it is compatible with nation＇s earthquake precursor network system,and the software on it can set flexible.Three years＇ observation bears the proof that the collector is stable and of great practical function.This paper mainly discussed sundry parameters and index of EAXJEQ-I earthquake precursor,its external panels and work progress with already known information.
