三层电梯的单片机控制电路
摘要 电梯在国民经济和生活中有着广泛的应用。为了适应电梯的迅速发展，我组开发了一套电梯控制系统。由于单片机的迅速发展和普及，而采用单片机构成控制系统，则可大大降低成本，而且做成专用控制系统，程序被固化，加强了保密性、提高了可靠性。但是使用单片机系统要注意加强软、硬抗干扰措施。
本文详细介绍了电梯控制系统的原理和电梯控制系统设计的制作思想，通过AT89C51单片机作为主控制器，加一些外围电路ADC0809、8255等控制芯片组成了电梯控制系统的硬件配置，以及软件设计方法和软、硬件的抗干扰措施。

The single slice machine of three layers of elevators controls electric circuit
Abstract The elevator has an extensive application in the national economy and the life.For the sake of the quick development of orientation elevator, I the set developed the control system of a set of elevator.Because single slice machine of quick develop and make widely available, but adopt single slice organization to become control system, then can decline consumedly low cost, and make into appropriation control system, procedure drive solid turn, strengthen a confidentiality and raise credibility.But use single slice machine system and notice to strengthen soft and hard anti- interference measure.
This text introduced an elevator control principle and elevator of the system to control the creation thought of[with] system design in detail, passing the AT89 C51 single slice machine was a main controller, the hardware which adds the control chip of some outer circle electric circuit ADC0809s, 8255 etc.s to constitute elevator a control system installs, and software design method with soft, the anti- interference measure of the hardwareKey
