Abstract
Research the use of a microcontroller design a new type of automatic control system of lifts. According to the current operation of hoists, automatic position detection. In accordance with set requirements, control rise, decline, hoists and accurate call-layer. Circuit simple system hardware, software, functional flexibility, easy operation, maintenance, and all the reliable. In fact lifts running, there are security issues. For example, construction of the lift is the most widely used in the vertical transport of machinery and equipment, security incidents occur from time to time,so how to ensure the safety of their use of it is particularly important. Statistics show that, among the many construction lift safety incidents, accidents are the number one killer of out of the top of the building. It is not only the high incidence of and against the most serious consequences. There are no customs gate, and emergency power-down operation, overloading and to the electrode, such as plugging.
