Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0039] figure 1 A schematic topology diagram of the network structure of the ad hoc network provided by the embodiment of the present invention, such as figure 1 As shown, the ad hoc network structure in this embodiment includes a master control module and n slave modules, where n is a natural number greater than or equal to 1. The master control module and the slave module are sequentially connected through a communication interface to form a ring network structure; and both the master control module ...

Abstract

The invention provides an ad-hoc network structure and a diagnosis method thereof, and the method comprises the steps: a master control module sends a scanning frame to an adjacent driven module froma communication interface at one side when the state of a ring network of the ad-hoc network structure is normal; after receiving and identifying the scanning frame, the slave module generates a selfequipment identification number according to the scanning frame; the slave module inserts an equipment identification number of the slave module into the scanning frame to obtain an updated scanning frame; the slave module sends the updated scanning frame to the next adjacent slave module, or the master control module records the updated scanning frame fed back by the last slave module as a targetscanning frame, wherein the target scanning frame comprises equipment identification numbers of all the driven modules; and the master control module completes configuration of all the driven modules. According to the method provided by the invention, an engineer does not need to configure the device identification number for each device one by one, and the network position of each device in thenetwork and the fault point when a link or a device fault occurs can be automatically identified.

Description

technical field [0001] The present invention relates to the field of industrial control network technology, in particular to the network structure of an ad hoc network and its diagnosis method. Background technique [0002] Industrial networks, especially ships and other special applications, have high requirements for the availability and reliability of communication. In some applications with long distances and many nodes, the ring network topology is not only suitable for hierarchical networking and line saving. There are advantages that other network topologies do not have in terms of resources (such as optical fiber, cable, etc.), or in terms of ensuring communication reliability. [0003] Before the industrial ring network system constitutes the system, it is often necessary to configure each module in the system, such as the device factory ID, physical MAC address, etc. When the system scale is large, configuring each module one by one not only makes the workload hug...
