Embodiment Construction

[0038] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0039] The time calibration method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the device to be calibrated 102 communicates with the server 104 through the network. The device 102 to be calibrated sends a time calibration request for the first time to the server 104, and the first time synchronization information fed back by the server 104 is to be received, and the internal RTC of the device 102 to be calibrated is calibrated for the first time according to the first time synchronization information; The...

Abstract

The invention relates to a time calibration method and device, computer equipment and a storage medium. The method comprises the following steps: sending a first time calibration request to a server,and carrying out first time calibration on an internal RTC according to first time synchronization information when the first time synchronization information fed back by the server is received; and sending a second time calibration request to the server, and after second time synchronization information fed back by the server is received, performing second time calibration or re-performing firsttime calibration on the internal RTC according to the second time synchronization information and the current moment of the internal RTC. By adopting the method, time errors can be effectively eliminated, and higher time calibration precision can be achieved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a time calibration method, device, computer equipment and storage medium. Background technique [0002] GPS positioning technology is widely used in the world, and the time accuracy of equipment will affect the accuracy of positioning. Therefore, the time calibration of GPS equipment is very important. [0003] In the prior art, the first implementation of the time calibration of the GPS device is: the time obtained by the server or GPS is used as the reference time for time calibration; the second implementation is: the terminal device receives the first time from the network device A time information; receive a downlink signal from the network device; send an uplink signal to the network device; receive second time information from the network device, and the second time information is used to determine the receiving moment when the network device receives t...
