[0002] With the rapid development of today's electronic technology, time synchronization technology has also been increasingly valued and applied. Time code IRIG-B, as an important time synchronization transmission method, has become the preferred standard code type of time unification equipment with its outstanding superior performance, and is widely used in important industries and departments such as telecommunications, electric power, and military. As early as 2005, State Grid has clearly required in the "Notice on Strengthening the Management of Electric Power Secondary System Clock" to use IRIG-B standard code to gradually realize time synchronization of GPS devices and related systems or equipment.
