Abstract:With the deepening of the urban construction, high building has increased, the elevator in the national economy and life in a wide range of applications. The lift, as the high-rise buildings in the vertical transportation operation has and People's Daily life are inseparable, it expanded the existence of people space for the development of the cause of high-rise buildings made an indelible contribution. The modern science and technology progress and rapid development, bring the elevator control technology of the great leap forward. Especially programmable controller (PLC) of application, make the elevator performance more safety and reliable. This article analyses the structure of the elevator and programmable controller and the basic knowledge of the principle of work, based on six elevator design of electric control system. Siemens S7200 series controller used programmable controller to realize intelligent control of the lift. Realization of elevator six automatic control.
Keywords: elevator，rogrammable logic controller，ntrol system
