Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] A system command right switching method based on multi-client nodes, the specific steps are as follows:

[0034] Step 1. Client node configuration and networking.

[0035] Such as figure 1 As shown, each client node that needs command rights in different areas (Area) forms a dual redundant ring network, and each client node is in the same position. figure 1 The solid line and dotted line of each client node in , represent the dual redundant circuit, and the dotted line is the backup circuit. Each client node is equipped with two network cards, and the IP addresses of the two network cards correspond to the identification n of the client node, respectively a.b.p.2n-1 and a.b.p.2n, where n is an integer greater than 0, a, b and p is an integer, and can take any value from 0 to 255. The a, b and p of the IP address of each client node are the sam...

Abstract

The invention discloses a multi-client node-based system instruction authority switching method. Researches on safe switching, especially switching of system instruction authority in multi-operation terminal application fields such as the naval architecture and ocean engineering industry are rarely disclosed. The method includes the following specific steps of: client node configuration and networking; instruction authority state identification of each client node which includes the steps of instruction authority acquisition and instruction authority rendering; and instruction authority switching which further includes the step that each client node on the Ethernet performs instruction authority request and transfer according to actual operational needs. According to the multi-client node-based system instruction authority switching method of the invention, application configuration of existing terminals are not needed to be largely modified, and instruction authority switching can be transplanted based on the configuration of actual application systems.

Description

technical field [0001] The invention belongs to the field of ships and marine engineering, and relates to a method for switching command rights of a system, in particular to a method for switching command rights of a system based on multi-client nodes. Background technique [0002] There are various types of equipment and systems in ships and ocean engineering, and real-time monitoring is required, including navigation safety, equipment safety, and life safety. The future trend is to gradually form monitoring integration. With the improvement of monitoring requirements for ships and offshore operations, the types and quantities of monitoring terminal equipment on various transportation and operating platforms such as ships and offshore platforms are also increasing. [0003] In recent years, the extensive application of redundancy technology in the field of ships and ocean engineering has greatly improved the operational reliability, safety, and survivability of equipment an...
