Embodiment 1

[0035] Such as figure 1 Shown, based on the train group control method of ad hoc network, described method carries out the following steps:

[0036] Step 1: Treat the train track as a network link and construct a train ad hoc network; regard the train as a transmission information flow with fixed length, speed and acceleration on the network link, and number each information flow;

[0037] Step 2: Randomly set a plurality of information nodes on the network link in the train ad hoc network;

[0038] Step 3: Obtain the number, fixed length, speed and acceleration of each information flow in the train ad hoc network in real time;

[0039] Step 4: count the number of information flows passing through the information node per unit time, as the flow of the information node, and record the number of the information flow of the resulting information node;

[0040] Step 5: Randomly group the information nodes in the network link to obtain multiple random information node groups; eac...

Embodiment 2

[0044] On the basis of the previous embodiment, in step 5, the information nodes in the network link are randomly grouped, and the method for obtaining multiple random information node groups includes: obtaining information nodes of multiple preset groups in the network link The data information of the information node, wherein the data information of the information node includes: at least one control factor and the number of currently grouped information nodes under the multiple horizontal parameter categories corresponding to each of the control factors; grouping the number of information nodes, constructing a first parameter matrix; obtaining basic information of information nodes, and sequentially classifying said information nodes into corresponding horizontal parameter categories in each said preset grouping according to said basic information; According to the number of currently grouped information nodes under each of the horizontal parameter categories after adding th...

Embodiment 3

[0050] On the basis of the previous embodiment, according to the basic information, classifying the information nodes into the horizontal parameter category corresponding to the preset group includes: obtaining from the basic information the information related to each Each horizontal parameter value corresponding to the horizontal parameter category; according to the preset division conditions of each horizontal parameter category, determine each of the horizontal parameter categories corresponding to each of the horizontal parameter values; divide the information node into a category that satisfies In each of the horizontal parameter categories of the preset division condition.

Abstract

The invention belongs to the technical field of ad hoc networks, and in particular relates to a method and device for controlling train groups based on ad hoc networks. The method executes the following steps: Step 1: regard train tracks as network links, and construct train ad hoc networks; Trains are viewed as traffic flows of fixed length, speed, and acceleration over network links, and each traffic flow is numbered. It realizes the abstraction of the train ad hoc network by treating the train track as a network link, constructing a train ad hoc network, and then treating the train as an information flow, and then using the network in the abstract train ad hoc network. The control model controls the train based on control commands, which significantly improves the control efficiency. At the same time, compared with the traditional method of constructing an ad hoc network and then controlling it, the control accuracy will also increase.

Description

technical field [0001] The invention belongs to the technical field of ad hoc networks, and in particular relates to a train group control method and device based on ad hoc networks. Background technique [0002] Ad hoc network is a network that combines mobile communication and computer network. The information exchange of the network adopts the packet switching mechanism in the computer network. The user terminal is a portable terminal that can be moved. Each user terminal in the ad hoc network has a router. And host two functions. As a host, the terminal needs to run various user-oriented applications, such as editors, browsers, etc.; as a router, the terminal needs to run the corresponding routing protocol, and complete the data packet forwarding and routing maintenance work according to the routing policy and routing table, so Nodes are required to implement a suitable routing protocol. The goal of the ad hoc network routing protocol is fast, accurate and efficient. I...
