基于PLC的智能家居安防系统

摘要

随着我国经济的快速发展，生活水平的不断提高，人们对居家的概念已从最初满足简单的居住功能发展到注重对住宅的人性化需求。安全、舒适、快捷、方便的智能小区，已成为住宅发展的主流趋势，其中，安全性是首要目标。智能小区安全性的实现，除了人为的因素外，主要依靠小区的智能化安全防范系统。所以研究和开发智能家居安防系统具有很高的实用价值。在安防系统中，防火和防盗是主要的。因此，通过传感器把各种防火防盗的信号传输给小区报警中心，小区报警中心能迅速做出反应，阻止不法分子的得逞和火灾的发生。智能安防系统就是保障了人们居家的安全和利益，使人们的生活更加安全、舒适。所以设计和开发智能家居安防系统，不仅具有很强的现实意义，也有广泛的市场前景。

本设计介绍了西门子 S7-300的通信协议和工控组态软件WinCC在家具安防系统中的应用,并讨论通过用 MPI 网络实现 S7-300与工控组态软件WinCC 之间通信和用PROFIBUS-DP总线实现S7-300与S7-300之间通信的方法。

Based on PLC intelligent household security system

Abstract

With economy rapid developed and living standard continuous improved, people’s concept of home has changed from initial simple living function to the individual demands. The intelligent community, which is safe, convenient and comfortable, has become the housing development tendency. And safety is the primary target in that tendency. The safe of the intelligent community, except for human factors, mainly rely on safe guard system of intelligent community. So the research and development of intelligent household security system has high practical value. In the security system, fireproofing and security system is very important. Therefore, if transmit various fire-theft alarm signal to the community alarm centers through the sensor, community alarm centers can rapid reaction so that prevent the lawbreakers’ actions and prevent fire occurrence. Intelligent surveillance system is the guarantee for the security and interests of the housing people and makes the life of people more safe and comfortable. So the design and development of intelligent household security system, not only has a strong practical significance, bur also has wide prospect of market.

This design introduces application of Siemens S7-300 communication protocol and the industrial control configuration software security system WinCC in furniture security system. Then the paper discusses the methods which use MPI network to realize the communicating between S7-300 and industrial control configuration software WinCC, and use PROFIBUS-DP to realize the communicating between S7-300 and S7-300.
