【正文】 , but also can lower the elevator maintenance cost etc. It is one of the developing direction of intelligence building elevator control system. Keywords: PLC。 program design Ⅰ . Introduction In 1980s The first intelligence mansion had been pleted in America, then intelligence building has been abroadly taken attentions by the whole concept of intelligence building has been put different meanings along with the development of society. The early stage intelligence building had been thought that it is equal to the intelligent mansion, but now the intelligence building not only includes the intelligence mansions but also involves intelligence residential districts. This paper mainly discusses one subsystem of intelligence building system: the elevator control system. In intelligence residential districts the enterprise’s information managing system mainly takes charge of the things which related to the daily life, for example supervising the district equipments, managing vehicles, disposing critical situations and so elevator supervising and control system is also necessary to the intelligence residential to make people feel safe ,stable and fortable and how to save energy resources and protect environments and so on are the basic requirements to the elevator control system. PLC is a mon industry control is a special industry control puter which has the perfect function and simple frame. The PLC strong ability in interference and so on makes the elevator industry one after another to apply the PLC to the elevator control system, in order to replace the relay being used in traditional elevator control system. The Application of PLC in the elevator control system reduces the breakdown rate and efficiently improves the operating reliability of the elevator with safety. This paper mainly discusses the elevator control system’s working principles, the system’s software and hardware realization methods and so on. Ⅱ . The Working Principle of Elevator Control System In Fig. 1 the Hardware Structure Graph of Elevator Control System is presented. Fig. 1 The Hardware Structure Graph of Elevator Control System The Working Principles of Elevator Control System are stated as follows: The spot control information is send into the PLC from the customer input devices firstly, then the PLC control cabi is required to send out the control signal to drive the equipments according to the
