Real time Clock

  • Built-in Real time Clock is possible by using Epson RX8025 chip, the clock accuracy can be assured among @ 0.5s/d by embedded temperature chip, which will measures the internal temperature and performs temperature compensation according to the real temperature error curve of the clock.
  • Time synchronization between master station and concentrator can decrease the clock error to @ 2s/d. The process of time synchronization as follows:

DAQ sends Time Read Command to concentrator and its reply waiting time is 3 seconds.

If no replay is received in 3 seconds, the DAQ will resend the Command. If continuously 10 times command sending are with no reply in due time, the DAQ will stop sending.

DAQ will firstly calculate clock error ?T between concentrator and GPS clock.

If ?T<3 seconds, DAQ will not take time synchronization; If ?T=3seconds, DAQ will send time synchronization command to concentrator, whose clock will be adjusted by ?T+T1/2. The valid time for time synchronization is 10 minutes. If exceed 10 minutes, the time synchronization command will be invalid. In addition, the concentrator will report clock error automatically if time difference between clock of meter and concentrator exceeds allowed error.
