The Research On Environment Controlling Strategy Optimization Of Tianjin Metro Emcs

EMS is very important to subway system. As the scale of subway system growing up, the enviroment of subway station and fire problem in subway station are becoming the considerable problem to researcher. The speed of metro train up and the distance between two trains down result in the worse environment. The quantity of heat emitting from train increasing and the amount of people using subway system increasing make the temperature of subway up too. In some new subway system, air condition has become necessity that make the quantity of heat emitting from trains up. If EMS can't remove the heat, the temperature of air, soil and wall would increase in long term., that would made the subway system unwork. Therefore, the standard of building good subway system not only is offering a safty, comfortable environment to passenger, but also make lowing power cost, lowing building cost and lowing running cost in account.On background of EMS of subway line 1 and the typical subway station, the paper research on the typical subway station. Making summer as research environment, the paper offer 4 strategies on environment controlling and simulate these strategies, and then offer the most proper strategy.Background on the typical subway station, the paper analyse the controlling result of these environment strategies and which circumstance they are fitting for, and then conclude the most proper environment controlling strategy for different season.Another key research content on this paper is the controlling strategy when subway station catch fire. The paper offer 2 controlling strategies on catching fire in subway station, and simulate these strategies. Based on the simulation result, the paper analyses and concludes the most proper strategy for catching fire in different circumstance.
