基于PLC的智能住宅防火防盗系统设计

摘要

随着人们的居住理念的转变，对智能家居的要求越来越高，一些市面上常见的智能家居工艺商，对防火防盗系统的考虑往往不够全面，本课题从这一点展开，基于PLC系统完成智能家居防火防盗控制系统的设计。

首先，对防火防盗系统的控制要求进行分析，对课题的设计步骤进行分析，对使用PLC进行防火防盗系统设计的可行性进行简单论述。对防火系统中所用的烟感探测装置、防盗系统中所用的人体探测装置以及PLC的型号进行了合理选取，选用GRM200型短信报警装置，完成了PLC控制系统的硬件设计。最后本文给出了本系统的软件流程图，并完成了控制系统的软件梯形图设计。

Abstract

With the change of people's living concept, the intelligent Home Furnishing increasingly high demand, some common market intelligence Home Furnishing technology providers, the fire alarm system are not comprehensive enough, this topic from this point, PLC system design of intelligent fire alarm control system Home Furnishing based on.

Firstly, the control requirements of fire protection and anti-theft system are analyzed, the design steps of the subject are analyzed, and the feasibility of using PLC for fire prevention and anti-theft system design is briefly discussed. The smoke detection device used in the fire protection system, the human detection device used in the anti-theft system and the type of PLC are selected reasonably, and the GRM200 type SMS alarm device is selected to complete the hardware design of the PLC control system. Finally, the software flow chart of the system is given, and the software ladder diagram design of the control system is completed.
