To improve the accuracy of the electric energy meter clock
this project relies on the Electric Energy Data Acquire System(central station) to construct an electric energy meter clock management application based on a layered and segmented calibration strategy.The aim is to fully tap into the timing ability of devices at different levels through collaborative work layered and segmented.The central station ensures the accuracy of the central server clock by synchronizing it with a standard clock source.At the same time
the central station is responsible for segmented inspection
timing
and monitoring of terminals and meters
while the terminals enable autonomous heartbeat timing or NTP timing.Further
it performs collection
storage
and calibration tasks on the meter clock while ensuring its clock accuracy
achieving clock synchronization with the meter.The results show that this application effectively improves the electric energy meter clock's qualification rate and supports the power company's clock management service well.
