By studying the problems of the ASOM system encountered in monitoring at automatic weather stations, such as not in time, weather radar without sound and light alarm, etc, as well as grasping the operational state in time, collecting and sorting the relevant observation and supporting information, a secondary ASOM monitoring platform is established, and the efficient guaranteeing of the monitoring of the meteorological observing equipment is realized. The monitoring practice shows that this secondary monitoring system solved the problems existing in ASOM and made the ASOM system more convenient, timely, dependable, and accurate.
