Embodiment Construction
[0018] A synchronous time-keeping self-tracking and self-compensation method includes a self-tracking step and a self-compensating step.
[0019] When there is an external signal, such as GPS or IRIG-B, the reference clock data acquisition module receives the external signal, and digitizes the received signal, and at the same time performs advanced fault-tolerant judgment on the external input synchronization signal; specifically, first The falling edge of the external input signal is collected, and the absolute time scale of the falling edge change is recorded; secondly, when there are two edges, it is judged whether the time interval between the two edges is a unit time; if it is a unit time, according to the second The first edge generates the third edge through the hardware to prevent possible problems with the external third edge, that is, to perform advanced fault-tolerant judgment on the externally input synchronization signal.
[0020] If the above judgment is correct,...
