基于单片机的电梯控制系统设计

In many heavy industries, a large crane in lifting equipment, transport equipment, spare parts and maintenance, etc. plays a key role. In some modern production line of cranes operating very frequent. Therefore, its security, reliability, require very high. Also, because of high temperature plants, dusty, the operator of the difficult operating environment. View of crane operators are often limited by the need for operators with the ground. Crane operators and maintenance personnel to contact very difficult, it not only increases the security risks, but also so that efficiency is greatly reduced. Crane control motor current two ways, one way is to use wire running through the keyboard to control the crane's lifting hook up, down and stop the running of three. Another way is to use high-frequency wireless remote control method to achieve control of crane lifting hook of the rise and fall and stop the running of three. Two methods have advantages and disadvantages. This paper discussed the inadequacies of wire, a wireless remote control to control the crane of the program, mainly based on AT89C52 microcontroller as the control center through wireless communication module superheterodyne frequency communication module, through the PT2272 chip as the decoder chip, and through a pair of relays to control the lifting hook to control Reversible motor rise and fall lifting hook, by Hall sensor 44E to achieve lift-linked limit. This paper describes the hardware and software design. [资料来源：http://www.THINK58.com]
