Description
Technical field
The utility model provides the device for the time of settling the standard, specifically standard time treating apparatus.
Background technology
At present, the standard time is widely used in trajectory measurement, static fixing field, provides accurately real-time locating information.
The confirmed standard time uses cesium-beam atomic clock usually, but cesium-beam atomic clock manufacturing cost is high, and difficulty is large.
Summary of the invention
Determine to overcome the existing standard time defect that difficulty is large, the utility model provides standard time treating apparatus.This device processes by extracting time reference signal from GPS and big-dipper satellite, the technical matters that the solution standard time is determined.
The scheme that technical solution problem of the present invention adopts is:
Be respectively equipped with the first Big Dipper signaling interface in the circuit board, the second Big Dipper interface, a GPS synchronizing signal interface, the 2nd GPS synchronizing signal interface and 10MHz input interface, and VCXO unit is housed;
Also microprocessor unit is housed in the circuit board, silicon delay line, TDC measuring unit, D/A conversion unit and CPLD unit;
Be provided with the first output serial ports and second in wiring board side and export serial ports.
Good effect, compared with the utility model and cesium-beam atomic clock time determines, has structure simple, time signal source easily, the advantage of low cost of manufacture.The suitable application of installation determined as the standard time.
Accompanying drawing explanation
Fig. 1 is the utility model circuit board structure figure
In figure, the 1, first Big Dipper signaling interface, 2. the second Big Dipper interface, 3. a GPS synchronizing signal interface, 4. the 2nd GPS synchronizing signal interface, 5.10MHz input interface, 6. VCXO unit, 7. microprocessor unit, 8. silicon delay line, 9.TDC measuring unit, 10. D/A conversion unit, 11.CPLD unit, 12. first export serial ports, and 13. second export serial ports.
Embodiment
According to the figure, be respectively equipped with the first Big Dipper signaling interface 1, second Big Dipper interface the 2, one GPS synchronizing signal interface the 3, two GPS synchronizing signal interface 4,10MHz input interface 5 in the circuit board, and VCXO unit 6 is housed;
In the circuit board microprocessor unit 7 is also housed, silicon delay line 8, TDC measuring unit 9, D/A conversion unit 10 and CPLD unit 11;
Be provided with the first output serial ports 12 and second in wiring board side and export serial ports 13.
Described 10MHz input interface, be the interface to circuit board input 10MHz pulse signal, object is for wiring board provides the pulse power.
Utility model works principle:
By the time signal of the first Big Dipper signaling interface, the second Big Dipper interface, a GPS synchronizing signal interface, the 2nd GPS synchronizing signal interface and VCXO unit input, after microprocessor unit process, delay disposal is carried out by silicon delay line, the time signal detected is after TDC measuring unit is measured, be input to D/A conversion unit conversion, the time signal after conversion exports serial ports and second by CPLD unit from first and exports the outside outputting standard time signal of serial ports.
Concise and to the point low theory is: the time signal coming from the Big Dipper and gps signal and VCXO unit, after microprocessor coupling processing, detects time reference signal, changes through chip measurement, and the time reference signal detected is exported by serial ports.For the determination of standard time.
