In satellite communication, as a key of data transmission and exchange, the ground channel whose running state directly affects the service quality of different application terminal. The FY2 geostationary meteorological satellite is as the research object of the paper .Based on detailing the link design of ground channel and the design of centralized monitoring and management the paper deeply analyses the fault of monitoring acquisition in ground channel ,then, put forward the flow sheet of fault checking and monitoring method from the hardware and software .Next ,it provides the preventive measures from the construction and operation. Finally, it put forward the fault analysis and disposing measures according to the link outage. It may provide a fixed reference to the staff in the ground station of Satellite communication.
