Abstract

The invention relates to a time code IRIG-B adaptive decoding device and decoding method. The device comprises an input circuit. The input circuit comprises an electric B code input circuit and an optical B code input circuit. The output of the electric B code output circuit is connected with a photoelectric isolation circuit. The B code output circuit and the photoelectric isolation circuit areconnected with the signal selection circuit. The signal selection circuit is connected with the central processing unit. The time receiving device can adapt the input IRIG-B code signals of two physical modes, and a program can be adaptively recognized regardless of the input signal of a physical interface. The compatibility of the time receiving device is improved; the automatic signal recognition is supported, and the user As long as the optical or electrical IRIG-B code signal is connected to the device, there is no need to set it, and it automatically recognizes which channel has a signaland automatically decodes it; after the currently used signal is cut off, the system will automatically switch to a channel with signals.

Description

technical field [0001] The present invention relates to a decoding device and a decoding method, in particular to a time code IRIG-B adaptive decoding device and a decoding method. Background technique [0002] With the rapid development of today's electronic technology, time synchronization has been used more and more important. Time code IRIG-B, as an important time synchronization transmission method, has become the preferred standard code type for time system equipment due to its outstanding superior performance, and is widely used in military, electric power and other important industries or departments. [0003] In today's world of global integration, it has become my country's national strategy to combine China's national defense technology industry with civilian technology industry to achieve win-win cooperation between the military and civilian sectors. [0004] Traditional time-frequency receiving products are all customized to a specific format when receiving IRI...
