A communication system and timing method thereof

Abstract

The present invention provides a communication system and a timing method thereof. The timing method includes the following steps: the master controller obtains time information through a satellite timing device, and sends timing request information to each client at intervals of the first set time; the client receives After the second set time of the timing request information, send timing response information to the server; after receiving the timing response information, the server calculates the communication delay between the server and the client, and uses the time information obtained from the satellite timing device and The communication delay is packaged and sent to the client; the client corrects the local time according to the received time information and the communication delay, and monotonically increases the local time within the third set time and synchronizes with the server time. According to the technical solution provided by the invention, the time stamp on the information sent by the client to the server will not be repeated, thereby solving the problem that the communication quality is affected by the timing method in the communication system of the prior art.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a communication system and a timing method thereof. Background technique [0002] With the development of science and technology, communication technology is more and more developed and widely used in people's daily life and industrial production, which greatly facilitates the control and management of people's daily communication and industrial production. [0003] The structure of the communication system used in industrial production management usually includes a client, a communication node, and a server. The server is connected to multiple communication nodes, and each communication node is connected to multiple clients. The client receives the collected information and sends it to the communication node; the communication node is usually a gateway, router and other equipment, and sends it to the server after receiving the information from the client; the s...
