Study And Realization On Green Illumination System Of Railway Station

This dissertation studies a new type of green illumination system of railway station aim at the actually illumination of the Hankou railway station. This system combine the new type lamps and lanterns saving energy with advanced industry automatic control, proceed with hardware and software, solve the problem between saving energy and serving quality. IPC and PLC compose a distributed control system having the functions of control, observation, alert and database manager, which realize automatic management of illumination system.As components of control, IPC and PLC have many virtues. They can finish complicated logical operation. They are steady and reliable, having high speed of response and a good many of functions. They entirely replace the control method using relays in a lot of railway situation.In chapter 1, the domestic and foreign present state and develop direction of illumination and saving energy are summarized, the existent problems are proposed and solve project is also primary proposed.In chapter 2, the basic concept and principle of illumination is introduced, the mass project of the system is particularly expounded, the key technical problem which the system demand to resolve is proposed.In chapter 3, the constitute of PLC control system, work principle, the hardware circuit design and control codes are introduced.In chapter 4, it is particularly introduced that the work principle, network constitution of the computer control system, software flat -kingview and function module, as well as the communication program that can accept the information which train is in the station and which train is out of the station .In chapter 5, a summarization of the dissertation is given, the problem and prospect which are demanded to be continue studied are proposed.
