Based on available digital PS testing system and long-distance monitoring hardwares

the cyclical monitoring system for digital power supplies(PS) was developed at SSRF.Two models

i.e.long-distance cyclical monitoring and local cyclical monitoring

were established.The software developed in LabVIEW language was applied to the two models without any user interface modification.The user interface is simple.The system is suitable for debugging the digital PSs during long-distance monitoring and examining the performance.The long-distance model imitates the digital PSs’ status for fault analysis and communication between the digital PS and the centre control room.The local model simultaneously examines stability of 18 new PSs for 24 h

monitors the PS controller

and detects malfunction.Parameters and status of the controller can be stored in Excel or Text file.The two models have been used at SSRF for monitoring the digital PSs.
