Chain breakage treatment method for temporary train speed limitation

Abstract

The invention relates to a chain breakage treatment method for temporary train speed limitation, which comprises the following steps: 1, initializing tag reading and processing parameters; 2, judging a train running direction and setting up a direction indicating symbol; 3, receiving a tag via a radio frequency module, reading contents in the tag, determining tag information, and judging whether a survival pre-warning tag exists or not, i.e. mainly determining whether a train enters a speed limiting area or not; 4, judging the current chain breakage situation of the train according to the current kilometer value and the previous kilometer value, and judging whether a broken chain is a long chain or a short chain; 5, determining corresponding compensation operations according to the kilometer value information and chain breakage judgment results in Step 4, and judging whether the train runs out of the speed limiting area or not after compensation is completed, implementing Step 6 if the train runs out of the speed limiting area, and if the train does not run out of the speed limiting area, repeating Step 3, waiting to receive new tag information, and carrying out the next judgment and compensation; and 6, judging a finishing identifier of the speed limiting area. In case of power failure, the system needs to be restarted. In case of changes in the train number, all parameters need to be cleared to be zero. By adopting the method, the kilometer value related to chain breakage in temporary speed limitation process for the train can be handled in real time, and the running safety and running efficiency of the train can be guaranteed.

Description

technical field [0001] The invention relates to a chain breaking processing method for temporary speed limitation of trains, in particular to a method for processing the kilometer value of chain breaking during temporary speed limiting of trains, which belongs to the modification technology of the chain breaking processing method for temporary speed limiting of trains. Background technique [0002] In recent years, my country's railways have continued to speed up. At the same time, railway lines in some areas have been continuously updated. During the update process, due to local rerouting or segmental measurement, etc., the pile numbers are not connected, that is, the chain is broken. In the speed limit area, due to the existence of broken links, the change of line mileage marks is discontinuous, which brings problems to mileage point positioning. In the process of temporary speed limit, mileage point positioning is very important, and mileage point positioning is not accura...

AI Technical Summary

Problems solved by technology

In the speed limit area, due to the existence of broken links, the change of the line mileage mark is discontinuous, which brings problems to the mileage point positioning. In the process of temporary speed limit, the mileage point positioning is very important, and the mileage point positioning is not accurate. It will bring about the following impacts: 1) When the train is in the speed-limited zone, the railway kilometer value has a long chain, and the train may brake prematurely, so that the anchor point of the brake is advanced, and the train may stop before reaching the end point. This wastes time and reduces time

2) When the train is in the speed limit zone, there is a short link in the railway kilometer value, which will cause the brake delay of the train. The train may not meet the speed limit requirement when it reaches the designated position, and break into the speed limit zone at a higher speed, resulting in overspeed ACCIDENT

3) Improper handling of broken chains in the speed limit area. For passenger transport, sudden braking will affect the comfort of passengers. Overspeeding will threaten the safety of passengers. For freight, too slow train speed will greatly reduce the efficiency of cargo transportation. efficiency
