Abstract

The invention discloses an illumination analog system in high-speed vehicle passenger room, comprising a computer, an IGBT light modulator and a lamp set which are in turn connected, and an illumination sensor that is connected with the input end of the computer, wherein the lamp set and the illumination sensor are installed in the vehicle passenger room. According to the control characteristic of the rapid change of the illumination, the system combines the bang-bang control and the fuzzy control, parallel connects the lamp sets and controls them in groups, and has uniform illumination distribution and small illumination error; besides, the invention can tracking control the illumination change in each passenger room and well satisfies the research of the high-speed train illumination change on the passenger comfortableness effect relationship. In the current adjusting method, the illumination rapid change is analogized and the anticipant illumination value is rapidly tracked via the actual illumination. The bang-bang control is used for controlling the rapid change of the illumination and the fuzzy control is used for adjusting the overshoot of the illumination so that the precise control of the illumination is realized and the robustness of the illumination control system is increased.

Description

technical field [0001] The invention relates to a realization method of a system for simulating illuminance in a passenger compartment of a high-speed vehicle. Background technique [0002] In recent years, with the rapid development of high-speed rail, an important topic after the research on high-speed train operating speed, service reliability, and operational safety is the issue of passenger comfort during high-speed train operation. Some experts and railway experts have received great attention. At the same time, comfort is also the direction pursued by the development of high-speed train technology. It is related to the physical and mental health of passengers, and in-depth research is urgently needed. However, in the research process, there are many problems that need to be solved urgently, such as high-speed train comfort simulation test technology, comfort evaluation theory, comfort improvement optimization technology, etc. , a test system for the influence of diff...
