Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, electric power synchro system integral body comprises major clock, is equipped with clock, a plurality of from clock, and major clock is with clock is by gps antenna or Big Dipper antenna reception gps satellite or big-dipper satellite time signal fully, and the time signal that produces standard is exported.And by the realization wireless telecommunications of big-dipper satellite system.Major clock be equipped with clock and link to each other with IRIG-B sign indicating number (a kind of timing code) by optical fiber cable, major clock and be equipped with clock and provide time reference signal for whole movement environment, need not to insert again antenna from clock, they by signal cable with IRIG-B sign indicating number (a kind of timing code) B sign indicating number and major clock be equipped with clock and link to each other, and from major clock be equipped with clock and obtain time reference signal, major clock, pass through commercial power interface from clock, carry out mains frequency sampling, calculate, send the Peripheral Interface of data message by clock apparatus to computing machine then.
As shown in Figure 2, the frequency detection module of the utility model satellite synchronizing clock device comprises civil power acquisition interface, sensor, filtration module, signal condition module, signal limiter module, frequency counting module and gathers module computing time.The civil power acquisition interface directly is connected into the high-tension electricity that 220V exchanges, then carry out step-down, fall stream by sensor, carry out the waveform transformation of civil power again, sine wave is converted into square wave, carry out signal Processing, adjustment then, at last the sample count by frequency, calculate the corresponding time and export to center management module.
Wherein frequency detection module comprises center management module, detection module, this three parts function of host computer administration module.
The frequency detecting of the utility model satellite synchronizing clock device has following function:
A. centre management function
The centre management function mainly contains the function of two aspects: give center management module with state and temporal information, the frequency information real-time report of frequency detection module on the one hand, report to center monitoring management platform or monitoring of tools management system according to the frequency of setting simultaneously; Finish Distribution Center's monitoring management platform or the directly instruction assigned of the monitoring management system of connection device on the other hand.
B. frequency detecting function
Frequency detecting mainly is divided into two aspects: the one, to the sample count of mains frequency, calculate the accurate data of frequency, i.e. frequency.Be that sampling to mains frequency calculates temporal information on the other hand, and compare calculating, draw difference with the clock real time.
