Problems solved by technology

The characteristics are: the test error is greatly affected by the network environment, ranging from a few milliseconds to hundreds of milliseconds; the device under test is required to have NTP output
[0008] However, for electric power, telecommunications, and mobile networks, channel resources are limited, and the existing time synchronization monitoring method reduces the utilization rate of channel resources because the monitoring data channel occupies the channel alone.

Abstract

The invention provides a time synchronization monitoring method and system. The method includes sending monitoring information to a master-station time synchronization device through a precision clock protocol channel after a slave-station time synchronization device receives time service information sent by the master-station time synchronization device through the precision clock protocol channel and when the time service information is verified to pass; detecting the monitoring information according to local time information of a master station by the master-station time synchronization device to acquire a detecting result; sending time deviation in the detecting result to the slave-station time synchronization device through the precision clock protocol channel to perform time adjustment; uploading the detecting result to a background of the time synchronization monitoring system to perform storage, statistical analysis or threshold crossing alarm. By the time synchronization monitoring method and system, monitoring on time synchronization through a time service channel is realized, the problem that channels are only occupied by data channels in conventional technology is solved, and utilization rate of channel resources is increased.

Description

technical field [0001] The invention relates to the technical field of time synchronization, in particular to a time synchronization monitoring method and system. Background technique [0002] With the development of communication technology and data network technology, more and more industries and fields need to establish time synchronization systems. [0003] The application of time synchronization in the power industry is that the time between the collection and control equipment of the power plant is consistent, which is convenient for analyzing and monitoring the operation status of the power grid. The application of time synchronization in the telecommunications industry is mainly in billing and distributed data collection. The application of time synchronization in the mobile field is mainly the synchronization between base stations based on the time division multiplexing mechanism. [0004] From the perspective of network management and operation and maintenance, w...
