一、引言电梯作为垂直运输交通工具,是高层建筑必不可少的。现代建筑的不断发展,对电梯提出了越来越高的要求,这就使得控制系统越来越复杂,成本越来越高。近年来,以微电脑为核心的电梯控制系统不断被推出。与传统方式组成的电梯相比,它更具有可靠性、实用性和经济性。国内研制的以电脑为核心的单台电梯控制系统,已作为产品配套于电梯供用户使用。二、系统的硬件构成我们采用了INTEL公司的MCS-48系列单片机为核心构成电脑控制电路,其框图见图1。各部分的功能简述如下:
I. INTRODUCTION Elevators are essential for high-rise buildings as vertical transportation vehicles. With the continuous development of modern buildings, higher and higher requirements are placed on elevators, which makes the control system more and more complicated and the cost higher. In recent years, elevator control systems centered on microcomputers have been continuously introduced. Compared with elevators constructed in the traditional way, it is more reliable, practical and economical. The computer-based single elevator control system developed in China has been used as a product supporting the elevator for users. Second, the system’s hardware composition We use the INTEL’s MCS-48 series microcontroller as the core of the computer control circuit, the block diagram shown in Figure 1. The functions of each part are briefly described as follows:
