Problems solved by technology

[0003] However, with the expansion of the network of high-speed trains and the increase in operating mileage year by year, some problems have also been exposed, among which the hazards of air pollution to the exposed key components of high-speed trains are particularly prominent
In addition, when the content of SO2, NO2, etc. in the train operating environment is too high, it may cause pitting and corrosion problems of exposed key components such as pantograph parts, contact network, and bogies, thereby reducing the use of exposed key components life expectancy, economic loss

Embodiment Construction

[0092] The present invention provides a train operation protection method and system under air pollution environment, capable of real-time monitoring of the concentration of air pollutants at the exposed parts of the roof and bottom of the high-speed train, and using the deep network, according to the measured concentration of pollutants The data acquires the pollution status level of the corresponding key components during operation, and a reasonable cleaning and protection method is selected after docking. Among them, the pollution status of key components is obtained through deep network training, the input of the model is various measurement data, and the output is the level of pollution status.

[0093] Such as figure 1 As shown, the train operation protection system in the air pollution environment includes roof air quality detection module 1, bottom air quality detection module 2, data transmission module 3, data processing module 4, platform data center 5 and platform ...

Abstract

The invention discloses a train operation protection method and system under an air pollution environment, wherein the train operation protection method under an air pollution environment includes: collecting multiple sets of roof and bottom air quality detection data; Bottom air comprehensive evaluation index Q 0 and Q 1 ; Calculate the exposure time T of the roof part 0 and underbody component exposure time T 1 ;Train the calculation model of the pollutant state of the roof part and the calculation model of the pollutant state of the bottom part; after the train stops, detect the air quality detection data of the roof and the bottom of the car; call the calculation model of the pollutant state of the roof and the bottom part, and find The pollution level of the roof and bottom parts is obtained; according to the obtained pollution level of the roof and bottom parts, the corresponding cleaning and protection treatment is carried out for the roof and bottom parts. The invention evaluates the exposure status of the key components of the train in the air pollution environment, and takes relevant protective measures to ensure the normal service life of the key components of the train.

Description

technical field [0001] The invention particularly relates to a train operation protection method and system under air pollution environment. Background technique [0002] High-speed trains have developed rapidly in my country in recent years. As one of the resource-based and environment-friendly modes of transportation, accelerating the development of high-speed trains has now become the consensus of all aspects of society. It has become the artery of my country's national economic development, and it has the characteristics of safety, economy and convenience. These characteristics determine its transition to a popular means of transportation, and it is in the backbone position in my country's comprehensive transportation system. [0003] However, with the expansion of the high-speed train operating network and the yearly increase in operating mileage, some problems have also been exposed, among which the hazards of air pollution to the exposed key components of high-speed ...
