Problems solved by technology

[0004]1. Beidou GPS positioning type, using Beidou satellite positioning can provide all-round, all-weather, all-weather positioning information, but it is not suitable for train positioning in tunnels
[0005]2. Wireless base station type, using wireless base stations at both ends of the tunnel to provide train information, effectively reducing the use of trackside equipment along the line, but not suitable for train positioning in the tunnel
[0006] 3. Response type, arrange multiple trackside equipment along the railway line, and install corresponding on-board equipment on the train at the same time, with improved accuracy, but the engineering cost and The maintenance cost is huge and the practicability is poor

Embodiment Construction

[0047] Concrete steps of the present invention are as follows:

[0048] Step 1: Collect tunnel atmospheric pressure and meteorological parameters, and build a database of tunnel atmospheric pressure and meteorological parameters

[0049] The on-board sensors distributed at both ends of the train collect the temperature, humidity and air pressure series in the tunnel when the train passes in real time, and the mileage time series of the train in the tunnel are collected through the responding devices installed in the tunnel and on the train in advance, and the sampling frequency is 10Hz. The average value of temperature and humidity collected at T min before the train enters the tunnel is used as the estimated value of the average value of local temperature and humidity. The temperature series, humidity series, and air pressure series collected by the sensors located at both ends of the train when the train passes through a tunnel once, and the estimated values ​​of the average...

Abstract

The invention discloses a passenger comfort-oriented train tunnel passing duration calculation method, comprising the steps: obtaining an air pressure meteorological parameter sequence when a train passes through a tunnel through vehicle-mounted temperature, humidity and air pressure sensors installed at the head end and the tail end of the train, obtaining a mileage sequence from the current position to a tunnel exit through a response type device installed in advance, and constructing a tunnel meteorological parameter database; realizing tunnel air pressure meteorological parameter classification in the database through building division and an average temperature distribution model; on the basis, carrying out typical sequence extraction on each category, and constructing an RGB color image joint template matching model; establishing an LSSVM error model for an output error of the RGB color image joint template matching model; and finally, organically fusing the two models to realizeaccurate calculation of the duration of the train passing through the tunnel.

Description

technical field [0001] The invention relates to a method for calculating the duration of a train passing through a tunnel for passenger comfort. Background technique [0002] Since entering the 21st century, the development of China's high-speed rail has gone through from foreign introduction to absorption and digestion to independent research and development. High-speed trains have driven considerable development in my country. After R&D technicians put a lot of energy into ensuring the safety and safety of trains, the comfort of riding has become the focus of current related research. Improving the passenger experience of passenger trains throughout the journey is conducive to enhancing the competitiveness of high-speed rail passenger transport. Comprehensive information prompts are conducive to allowing passengers to grasp the current train operation conditions and improving passenger experience. At present, the prompt information in the car includes air temperature and...
