Description

Regional clock movement

Technical Field

The utility model relates to a timing instrument technical field especially relates to a technical field of regional clock core.

Background

The existing pointer type quartz clock products on the market which can be used for indoor automatic time calibration mainly have 3 types:

the first type is a quartz clock with local area network timing function, which receives the standard time of mother clock or NTP server through network, the network has various forms, the most common is 485 network, Ethernet local area network or CAN network, the biggest disadvantage of the clock is that it CAN not adapt to the independent application without network, and needs to arrange communication line separately, and it is mainly applied to office building, hospital, railway, square and other large-scale occasions.

The second type is a GPS time service clock, which is generally calibrated by receiving time information through a relatively long outdoor GPS antenna, or receiving GPS master clock server information in a network by using various networks, wherein the GPS time service clock is actually a local area network time service clock of the first type. The biggest defects of the quartz clocks are as follows: the clock reader or the GPS master clock system in the network needs to be provided with a GPS antenna outdoors, even in the independent application occasion without the network, the clock reader must be connected with the outdoor antenna, and particularly in the finished occasion, the construction and the installation are very inconvenient.

The third type is a radio-controlled clock, which receives radio-controlled signals transmitted by a radio-controlled long-wave time service station to calibrate the clock and can be powered by a battery, but the biggest defect is that only one radio-controlled long-wave time service station is provided in China, the coverage range of the radio-controlled long-wave time service station is not perfect, even in the covered area, the signals in the building are weak, the standard time of the radio-controlled long-wave time service station cannot be received at many times, and the radio-controlled long-wave time service station has strict requirements on the address position. And its radio wave decoding circuit is complicated, decodes loaded down with trivial details, needs longer time location standard time, goes out machinery and circuit trouble easily, and the core is in case the trouble just must be changed whole core, and the cost is very high. The other disadvantage is the monopoly of foreign encrypted radio wave clock circuits in China, and the development of the clock industry per se in China is not facilitated. The power supply of the radio-controlled clock can only be supplied by a common battery, the power supply time can only be maintained for about 1 year, the radio-controlled clock needs to be replaced every year, the signal of the radio-controlled clock is sometimes influenced by weather or seasons, and a plurality of signal-free dead zones exist in coverage areas of different regions.

When the radio-controlled clock works, if a radio-controlled signal exists, the time is generally corrected once in one minute, the working mode has low requirement on the quartz clock crystal oscillator, which is the advantage, but the whole machine core is additionally provided with a receiving and decoding circuit of the radio-controlled signal, the structure is complex, the decoding efficiency is low, and the maintenance is not facilitated. And the moment of the electric wave clock is small and is only suitable for the indoor clock with a small panel. The CDMA quartz clock technology uses the precise satellite time provided by the network signal of the CDMA mobile phone as a standard time clock. At present, the development of human society has entered the 5G era, and second-generation mobile communication networks such as GSM and CDMA, etc. gradually become 'obsolete networks', and are closed by mobile operators in more and more countries. Particularly, with the arrival of the 5G era, due to the high speed, high reliability and low time delay characteristics of 5G, information is transmitted for billions of devices in the fields of medical health, automatic driving, public utilities, smart cities, logistics and the like, the development of a 5G network is promoted to the national strategy, and in the aspect of network construction, more than 60 thousands of 5G base stations cover all cities above the grade of the country. However, how to use the precise time provided by the 5G network signal as the standard time to calibrate the local clock provides a local clock movement with random placement position, low energy consumption operation, no maintenance, automatic time calibration and hour/minute/second pointer time service, low cost and intellectualization for the society, which is a technical subject to be solved by technical personnel in the technical field.
