Problems solved by technology

[0007] 1. Although it is convenient to install a portable temporary speed limiting device on any railway section, it is less flexible, and the installation and disassembly work will also involve related manpower organization and arrangement
[0008] 2. The way of managing the temporary speed limit information through the IC card needs to update all the locomotives performing the transportation task every time the temporary speed limit information changes. Since there are many drivers and locomotives involved, it will consume a lot of manpower , it is also easy to cause management mistakes
[0009] 3. Due to the lack of verification between the set temporary speed limit information and the executed temporary speed limit command, it is easy to cause inconsistencies between the set temporary speed limit information and the executed temporary speed limit command, resulting in safety accidents

Abstract

The invention relates to railway traffic, and discloses a heavy-haul-railway temporary speed limitation method based on moving blocking and a temporary speed limitation server. The method includes the steps that first temporary speed limitation information is received from centralized traffic control equipment; the first temporary speed limitation information is sent to a wireless blocking center; when the wireless blocking center receives efficient temporary speed limitation information in first preset time, it is determined that whether or not the first temporary speed limitation information accords with the efficient temporary speed limitation information; when the first temporary speed limitation information accords with the efficient temporary speed limitation information, the first temporary speed limitation information is stored, and a command is sent to make the wireless blocking center adopt the efficient temporary speed limitation information to conduct speed limitation on a heavy haul train. By the adoption of the heavy-haul-railway temporary speed limitation method based on moving blocking and the temporary speed limitation server, dynamic setting, canceling and checking of temporary speed limitation are achieved, the pressure of operators is alleviated, at the same time, hidden risks which can be caused by manual operation are reduced to the maximum degree, and the safety of the system is improved.

Description

technical field [0001] The invention relates to rail traffic, in particular to a mobile block-based temporary speed limit method for heavy-duty railways and a temporary speed limit server. Background technique [0002] In the process of heavy-haul train transportation, when a certain section of a specific line is under construction or the operating conditions of the line change, it is often necessary to set a temporary speed limit within a certain range of the line. The current method is still the traditional way of placing temporary signs or using walkie-talkies to inform drivers. These two methods are greatly affected by human factors, and there are major security risks. With the substantial increase in the operating density of heavy-haul trains, higher requirements are placed on the reliability of temporary speed limits. In order to better monitor the operation of trains in the temporary speed limit section, a more effective and safe way is needed to manage the temporar...
