Embodiment Construction

[0019] The present invention is described in detail below in conjunction with accompanying drawing:

[0020] The troubleshooting method of communication equipment, the specific steps are as follows:

[0021] Step 1. Each terminal is connected through the TD-LTE wireless network, and the terminals with similar distances are connected with the wired network to complete the data and voice transmission services; after the dispatching center is started, it analyzes the network information of each terminal to obtain the group Topology map of network information;

[0022] Step 2: Using a dynamic programming method to calculate the nearest adjacent terminals relative to each terminal. The method is as follows:

[0023] Assuming that the node of the terminal is A0, and the maximum number of terminals sharing data is N, first traverse the nodes directly connected to it according to the network matrix. Then traverse the indirectly connected nodes from the directly connected nodes, and...

Abstract

The invention provides a fault handling method based on data sharing for rail transit communication equipment. The method comprises the following steps that: each terminal is connected through a TD-LTE (Time Division-Long Term Evolution) wireless network, and terminals which are close to each other are connected through a wired network in order to finish data and voice transmission services; when a scheduling center issues control information to a certain communication terminal, the scheduling center transmits the information to other terminals which are adjacent to the terminal at the same time to perform data sharing; when a wireless communication fault occurs in a certain terminal, the control information of the terminal can be obtained by accessing of shared data of the adjacent terminals through the wired network, and an error report can be transmitted to another terminal through the wired network; and when the other terminal receives the error report, the other terminal transmits the received error report to the scheduling center through a wireless network of the other terminal. Through adoption of the method, information exchange between the scheduling center and a fault terminal is ensured, and a troubleshooting aim is fulfilled.

Description

technical field [0001] The invention belongs to the technical field of TD-LTE communication, and relates to a fault handling method for rail transit communication equipment based on data sharing. Background technique [0002] With the development of communication technology, it is very necessary to carry out stable communication between terminals during the operation of rail trains. At present, the TD-LTE private network has been able to meet the high-bandwidth and stable communication between terminals. This kind of communication includes two parts, one part is voice communication, each terminal can carry out voice communication, and the other part is data communication, each terminal can send data and control information. [0003] In the prior art, only voice communication is performed between each communication terminal, and data communication is performed between each terminal and the dispatching center. During the communication process of rail transit, it is necessary t...
