Analyse And Research On Illumination Based On City Tunnel

The major problem exist in the tunnel is when the car enter the tunnel in the day, there would be occur the "black frame" or the "black hole" phenomena because of the deficiency of the illumination in the tunnel. The drivers need a span time to adapt the differences between the illuminiation ouside the tunnel and illumination inside the tunnel. This brings the drivers to a certain degree of psychological pressure, and make the accident easer to occur. The reverse is the case the night, drivers come into a brighter environment from a darker environment, this brings the drivers to a certain degree of psychological pressure if the difference is too big. As everyone knows, it is much more harder to deal with the accident in the tunnel as the accident out of tunnel, so the illumination in the city tunnel became more and mord important.Take the moniter system of the Zhongshan Road underground passage for example, to put forward a strategy which is suitable for the city tunnel to control the illumination system in the tunnel According to the actual situation. It is because there is no standard with the city tunnel today, reference standards of Highway Tunnel to put forward a new formula with city tunnel. There also established a intelligent model with the neural network and fuzzy-control.To introduce The overall functional requirements and design basis of illumination system in detail. It also introduces basic information of the PLC controller and configuration software. Then detailed account of the PLC controller and the configuration software features and product development situation inside and outside the country. Discusses the similarities and differences between the Distributed Control System and Fieldbus Control System in detail.To expatiate the system architecture of illumination system and the type of sofeware and hardware. To introduced the different subsystem of the illumination system, and analyse the functional requirements of the different subsystems. As a result it confirms the illumination distinctness, illumination control and illumination plan management to be the three key modules. Then expatiate the design and e implementation of each functional module. To introduce how to implementate the User Interface of different subsystems and database functions. Implementate the stategy which put forward before in the illumination control module.Finally, to expatiate the result of the system control. It shows that the illumination system can control the illumination of city tunnel well by analysis the details of the collecion data. That is to say the illumination achieved the expected goals. It is also explain the unfathomed problems and the function can be optimized in the illumination system. That could be the refernce of the latter research.
