毕 业 设 计 (论 文)课 题基于 PLC 的建筑设备自动控制系统设计 —— 照明控制系统设计 摘 要大学的电能消耗中，照明用电占有绝大部分，其中教室的照明容量大、工作时间长，且常常采纳手动的控制方法，造成了浪费。因此针对学生的生活学习规律对教室的照明进行了 PLC 智能控制。本论文阐述了某教室的照明控制系统的设计思路、系统方案的选定、设备的选型、控制程序的编制与调试等等。采纳了 PLC 智能控制，系统稳定可靠完全满足教室的照明要求；根据 PLC 控制原理对其进行 I/0 分配和绘制照明系统流程图与编写教室照明智能控制系统梯形图控制程序。最后经过模拟仿真运行能够实现教室的智能化照明。最终使灯具的使用寿命也有所提高,系统稳定可靠，完全满足了教室的照明要求，达到了预想的结果。关键词：PLC，节能，西门子 STEP7-300，智能控制Abstract At the university of power consumption, lighting electricity possession for the most part,The classroom lighting of large capacity, long working hours, and often use manual control method, caused the waste. The students for life of learning rule PLC intelligent control of the classroom lighting. This paper expounds some classroom lighting control system design, selection of system scheme, equipment type selection, control program compiling and debugging and so on. adopted PLC intelligent control system is stable and reliable completely satisfy the requirement of the classroom lighting; According to the principle of PLC control on the I/0 distribution and mapping lighting system flow chart and ladder diagram writing classroom light intelligent control system control program. Finally through the simulation operation can be achieved within the classroom intelligent lighting. Eventually make it also improved the service life of lamps and lanterns, the system is stable and reliable, completely satisfying the requirements of the classroom lighting, to achieve the desired results.Keywords: PLC, energy saving...
