Abstract

The invention provides a wireless clock module, comprising a wireless timing circuit, an internal MCU, a crystal oscillator and an RTC chip; wherein the crystal oscillator is communicated with the RTCchip for driving the RTC chip to accurately travel; the wireless timing circuit and the RTC chip are respectively communicated with the internal MCU; the internal MCU is configured to receive a timing instruction of the user, control the wireless timing circuit to acquire a standard UTC time and then perform timing on the RTC chip according to the standard UTC time; the wireless timing circuit isused to access an external NTP server under the control of the internal MCU and obtain a standard UTC time. The invention also proposes a wireless timing method. The wireless timing module and the wireless timing method provided by the invention eliminate the accumulated error caused by the self-precision in the local time travel process in other calibration schemes, so that the calibration process is more convenient, faster and more accurate.

Description

technical field [0001] The invention relates to the field of wireless network and computer application, in particular to a wireless clock module and a wireless time calibration method. Background technique [0002] The existing real-time clock module (Real Time Clock, referred to as "RTC module") generally requires manual time calibration. After the calibration is completed, it is installed on the device again, or it is used for reference calibration with another local clock source, especially when it comes to In the case where multiple devices are required to maintain accurate time at all times, the above-mentioned time calibration method is not only inconvenient to operate, but also has a large cumulative error, making it difficult to ensure that multiple devices maintain the same accurate time at the same time. Contents of the invention [0003] The object of the present invention is to propose a wireless clock module and a wireless time calibration method in order to s...
