摘要
为了实时发现仪器故障、干扰现象,针对新疆区域编写了质子磁力仪噪声检测报警系统。明确仪器记录、传输、处理过程;整理各地磁台资料,统计典型干扰曲线的形态、振幅等,设定合理的报警参数;通过实时的差分模型、曲线展示,利用VB语言和Microsoft Office Access数据库编写噪声检测报警系统。在地磁台实际应用中,成功地实现了自动报警。
In order to detect fault and disturbance of proton magnetometer, we build noise detection and alarm system in Xinjiang. We use data of each station to calculate typical disturbances for alarm parameter. Through real-time difference model, the noise detection alarm system was made up with VB and access data. We successfully complete alarm system during application.
