基于PROTEUS和KEIL的电梯驱动系统控制系统设计
经过基于Protuse7.5仿真实现的电梯控制系统，能控制电梯按照顾客的要求自动上下楼层。该系统最终实现了厅门呼梯登记显示模块，呼叫的集选和取消，电梯运行的方向及其停止。该系统操作方便，而且容易上手，加之有良好的健壮性能，能在日常生活中提供了便捷的代步工具。
Hardware circuit includes a main controller, the elevator control circuit and display circuit, the main controller MCU on AT89C51, elevator display use 1602LED. The paper firstly introduces basic principles and functions of AT89C51 MCU, LCD1602, secondly designs the control plan of the elevator to realize running, thirdly produces the thought of design and builds the frame of system based on the principles and functions of these components, And LCD1602 display of elevator running status While using LED lamp shows users’ key operate ,simple ,and intuitive. lastly designs circuit diagram in Proteus and lists the operating process of design system and related programs. The whole system distributes saved units and composes values accord to corresponding memory addresses through the programs written in MCU. (2012-05-07, C/C++, 72KB, 下载47次)
本装置是为测量人体静电综合电阻（包括人体、鞋、袜等的电阻）而设计的用直观的发光二极管显示装置。本仪器能对容易积累危险的人体静电的电阻（大于109～1010Ω进行检测与报警，又能当人体综合电阻过小（小于104Ω）时，工作人员不小心触及动力电（220Ｖ或380Ｖ）即引起触电伤人事故，也能报警。本仪器测量范围宽且分辩率高（八个数量级），有两种工作模式：＂脚－脚＂工作模式和＂手－脚＂工作模式，使其能适应多种测量要求。
工作人员虽穿防静电工作服或工作鞋，但当人员穿非防静电袜或非防静电鞋垫等时，人体产生的静电不能导入大地。该系统能同时测试两脚和人体间的综合电阻。当人体综合电阻过大时，静电不能泄漏进入大地而有静电放电的危险，该仪器报警。当人体综合电阻过小时，若工作人员不小心触及动力电（220Ｖ或380Ｖ）即引起触电伤人事故，该仪器也能报警，并且该系统能指示（测量）人体间的综合电阻值
This device is for measuring the human body resistance (including electrostatic comprehensive human body, shoes, socks, etc) and the resistance of the design of the light emitting diode with visual display device. This instrument can easy to accumulation of human body the resistance of the electrostatic dangerous (more than 109 ~ 1010 Ω detection and alarm, and can when the human body comprehensive resistance is too small (less than 104 Ω), employee accidentally touch power (220 V or 380 V) that cause electric shock wounding incident, also can report to the police. This instrument wide measuring range and high resolution (eight orders of magnitude), have two kinds of work mode: "feet-foot" working mode and "hand-foot" work mode so as to adapt to the DuoZhong measurement requirements.
Though staff wear anti-static work clothes or work shoes, but when people wear the anti-static sox or the anti-static insoles, etc, the human body to produce the static electricity can t import the earth. (2011-07-31, C/C++, 1997KB, 下载26次)
