Abstract
The utility model discloses a time correcting device and an electronic clock. The time correcting device comprises an antenna, a modem and a processor which employs a wireless signal to correct the time. The antenna is connected with the modem. The processor which employs a wireless signal to correct the time is connected with the modem. The utility model has the beneficial effect that the time of the time correcting device is updated by receiving time data from the broadcast, so that the local time and the time of a broadcast time service system are consistent, greatly enhancing the time precision.
Description
Technical field
The utility model relates to a kind of time correction device and electronic watch.
Background technology
Existing clock and watch much adopt the quartz crystal oscillation source, and the vibration precision of quartz crystal oscillation source can change along with the variation of environmental factor (such as temperature etc.), and therefore in rugged surroundings for a long time after the operation, the error of clock and watch then can be apparent in view.In addition, much be installed on the clock of outdoor public place, like the clock on the square, owing to be difficult to safeguard, if the inaccurate situation of time of origin, placement is just keeped in repair for a long time through regular meeting, influences very big.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model discloses a kind of time correction device.
A kind of time correction device comprises antenna, modulator-demodular unit, utilizes wireless signal to carry out the processor of clock correction, and said antenna is connected with said modulator-demodular unit, and the said processor that utilizes wireless signal to carry out clock correction is connected with said modulator-demodular unit.
A kind of electronic watch comprises described time correction device.
The beneficial effect of the utility model is: owing to through the time data that receives in the broadcasting time of time correction device is upgraded, make the local time and the time of broadcasting time dissemination system be consistent, improved time accuracy greatly.
Description of drawings
Fig. 1 is a kind of synoptic diagram of specific embodiment of the time correction device of the utility model.
Embodiment
Below will combine accompanying drawing, the embodiment of the utility model will be done further explain.
As shown in Figure 1; A kind of time correction device; Comprise antenna, modulator-demodular unit, utilize wireless signal to carry out the processor of clock correction, said antenna is connected with said modulator-demodular unit, and the said processor that utilizes wireless signal to carry out clock correction is connected with said modulator-demodular unit.
Usually, common radio broadcasting all can be carried out manual work and gives the correct time when integral point, integral point report finish after; In broadcasting, send coordinated universal time (UTC) data; This time data is received by time correction device through antenna, after the process modem recovery becomes data, is processed device and receives.Processor with the time data that recovers (comprise year, the moon, day, the time, branch, second) time of this locality is proofreaied and correct; And this time is stored in the time memory cell of storer; Timing unit then is as the criterion with this time and carries out reclocking, and the current time in the regular update time memory cell.
Therefore this time correction device can be used for a lot of occasions, such as electronic watch owing to realize that simply cost is low.
Claims (2)
1. time correction device; It is characterized in that: comprise antenna, modulator-demodular unit and utilize wireless signal to carry out the processor of clock correction; Said antenna is connected with said modulator-demodular unit, and the said processor that utilizes wireless signal to carry out clock correction is connected with said modulator-demodular unit.
2. an electronic watch is characterized in that: comprise time correction device as claimed in claim 1.
