Sewage discharge control method for rail trains

Abstract

The invention relates to a sewage discharge control method of a rail train. The method comprises the steps that a controller judges whether the train is in a speed rising stage or a speed dropping stage according to continuously-collected train speed signals; if the train is in the train speed rising stage and no outbound sewage discharge mark exists, sewage discharge is performed on the condition that it is judged that the current train speed is larger than the set outbound speed V1, and the outbound sewage discharge mark is recorded; if the train is in the train speed dropping stage and no inbound sewage discharge mark exists, sewage discharge is performed on the condition that it is judged that the current train speed is smaller than the set inbound speed V2, and the inbound sewage discharge mark is recorded; when the train speed signals judge that the train speed is V3 or below, the outbound sewage discharge mark and the inbound sewage discharge mark are cleared. The sewage discharge control method of the rail train has the advantages that the problem that the train discharges sewage in a station is solved, and not only is the environment in the station protected, but also the normal needs of passengers on the train are not influenced. The sewage discharge control method of the rail train embodies improvement of a train technique and is the necessary trend of high-speed rail development of China.

Description

technical field [0001] The invention relates to a sewage discharge control method for rail trains. Background technique [0002] With the progress of society, people have higher and higher requirements for the environment and services. In the past, when the sewage tank was full, the train would still discharge domestic sewage even in the station. In order to maintain the sanitation of the station environment, passengers were restricted from using it before the train arrived at the station. This has not kept up with the requirements of the times. How to prevent the train from discharging sewage in the station due to the overfilling of the sewage tank while ensuring the normal use of the passengers in the train, so as to ensure the sanitation of the station environment, is a technical problem to be solved urgently when designing the rail train drainage system. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sewa...
