摘要（英）：

The utility model belongs to the B sign indicating number time service field of synchronous time service, in particular to IRIG decoding device is compiled to B direct current sign indicating number. The utility model discloses a time receiving module, IRIG B sign indicating number output module, IRIG B sign indicating number receiving module, time output module, volume decoder module and constant temperature crystal oscillator, does the signal input part who compiles decoder module receive and comes from time receiving module, constant temperature crystal oscillator, IRIG respectively B sign indicating number receiving module's TOD time and second pulse, synchronous frequency, IRIG B direct current sign indicating number, does the signal output part who compiles decoder module export IRIG be B direct current sign indicating number, TOD time and second pulse respectively to IRIG B sign indicating number output module, time output module's signal input part. The utility model discloses do you not only realize IRIG the code of B direct current sign indicating number, modulation walk abreast in ARM microprocessor system MSS, FPGA modulation unit respectively and go on, demodulation, parallel the going on in FPGA demodulation unit, ARM microprocessor system MSS respectively of decoding, moreover the utility model discloses possess still that the design is simple, the time service precision high, the reliable and stable advantage of system.
