Abstract

The invention discloses an oil conveying pipe network time synchronization method based on dynamic compensation and graded transmission, and belongs to the technical field of oil conveying pipe network time synchronization. The method comprises the steps of: dividing clock nodes on the oil delivery pipe network according to a time synchronization sequence; serving an external time server as a time service node, providing initial standard time for clock nodes of the whole oil conveying pipe network, serving the clock node which is determined to be subjected to time synchronization first as a node to be subjected to time service, enabling the node to be subjected to time service to obtain standard time information from the time service node, then performing dynamic compensation on a local clock according to the obtained standard time, and finishing time synchronization of the first-stage clock node; taking the first-stage clock node as a time service node, and taking the clock node which is determined to be subjected to time synchronization in the second sequence as a node to be subjected to time service, so as to complete time synchronization of the second-stage clock node; and so on, completing one time of time synchronization of all clock nodesaccording to a hierarchical transmission type synchronization mode. The time synchronization precision and efficiency of the oil conveying pipe network are improved.

Description

technical field [0001] The invention belongs to the technical field of oil pipeline network time synchronization, and in particular relates to a time synchronization method for oil pipeline networks based on dynamic compensation and hierarchical transmission. Background technique [0002] In the process of oil transportation, when the pipeline ruptures and causes leakage failure, if the location of the leakage point cannot be located in time and accurately, it will lead to a large number of casualties and economic losses. However, the positioning accuracy of the leakage point largely depends on whether the data monitored by each monitoring station of the long-distance pipeline network is at the same time, so time synchronization is very important for the safety monitoring of the pipeline network. my country's oil pipelines are generally thousands of kilometers long and usually have many monitoring station nodes. Each monitoring station node is equipped with a clock module, ...
