PAGE PAGE V 基于PLC和MCGS在双电梯联动控制与模拟 2012年5月 摘要 随着现代城市的发展，高层建筑日益增多，电梯成为人们日常生活必不可少的代步工具。电梯性能的好坏对人们生活的影响越来越显著，因此必须努力提高电梯的系统的性能，保证电梯的运行既高效又安全可靠。采用PLC对电梯信号系统进行控制，开发出了完整的电梯控制软件，提高了电梯的控制水平，并改善了电梯运行的舒适感，使电梯达到了较为理想的控制效果。该系统具有先进，可靠，经济的特色。该电梯控制系统具有手动和自动功能，并具有指层，厅召唤，选层，选向等功能。具有集选控制的特点。 关键词：电梯，PLC，梯形图 Abstract With the development of modern cities, an increasing number of high-rise building, elevator become an indispensable means of transport of daily life. The quality of the life performance of the impact on people’s lives becoming more and more obvious ,it must strive to improve the performance of elevator systems, and ensure the operation of the life is safe , realiable and energy efficient. The use of PLC signals on the elevator control system, the development of a complete elevator control software, to improve the level of the elevator control and improve the operation of the elevator comfort, ao that the life to reach a more satisfactory control effect.The system has advanced reliable and economic characertics. The elevator control system has the drivers to run the operation and no drives or manual and automatic functions ,and has means layer called the office of the election story , election to the functions. With a set of features to control the election.
