Method and system for synchronously inserting network time

Abstract

The invention relates to a method and a system for synchronously inserting network time. The method comprises the following steps: S1, a client generating an NTP (Network Time Protocol) timestamp query information packet and sending the NTP timestamp query information packet to an optimal time server, wherein the optimal time server is a time server selected by the client according to an optimal time server algorithm; S2, the client receiving an NTP timestamp answer information packet generated by the optimal time server according to the NTP timestamp query information packet; S3, repeating S1 and S2, and executing S4 when the repeated times is N, wherein N is more than or equal to 5 and less than or equal to 10, the repeated time interval is t, and t is more than or equal to 10s and less than or equal to 30s; S4, the client calculating a time difference data mean by adopting an information packet filter algorithm; S5, the client calibrating the client time according to the time difference data mean; and S6,the client displaying the calibrated client time. By adopting the method and the system, the calibrating precision is high, the system is small, the scheme is easy to realize, and the hardware cost is relatively low.

Description

technical field [0001] The invention relates to the Internet field, in particular to a method and system for embedding network time synchronization. Background technique [0002] In modern life, there are many simple time display devices, such as wall clocks at home, bedside alarm clocks, electronic time displays in public places, time display devices in parking lots, etc. These devices usually do not have the ideal time-checking function . At present, in simple or small time display devices, two technologies are usually used to provide standard time: cable transmission time coding and long-wave timing technology. In addition, the standard time can also be obtained by using the global navigation satellite positioning system (such as GPS, GLONASS, Beidou, etc.), but its receiving equipment is relatively expensive, and it is not suitable for use in simple or small time display devices. [0003] The principle of cable transmission time coding technology is relatively simple. ...

AI Technical Summary

Problems solved by technology

However, the time display terminal equipment based on long-wave timing service technology needs to install a receiver and a decoder, and the sensitivity of the receiver directly affects the effect of the device receiving signals

Therefore, the cost of long-wave timing terminal equipment is relatively high, and whether the long-wave signal can be received normally is greatly affected by the geographical environment. In a more complex environment, it will not be able to receive long-wave signals normally

Its low cost performance and the harsh requirements of indoor receiving signal conditions reduce the convenience for people to use standard time to a certain extent.
