Design and Analysis of Home Control Complex System Based on PLC Technology

Abstract

The wide application of communication, automation, computer and other technologies not only provides a new direction for the development of home furnishing, but also makes the concept of “smart home” popular in recent years. The purpose of this study is to design a complex control system for smart healthcare home based on PLC technology. First, the research significance and background of this study are discussed, and the complex system, traditional PID control, and BP neural network algorithm are summarized. Second, the ZigBee wireless sensor network and PLC control system are studied, and the design of a smart health home control complex system based on PLC technology is analyzed. The experimental results show that when the indoor natural gas concentration is more than 1.25%, Y4 and Y3 are powered on, and Y2 is set as 1, that is, the alarm light is on, and the windows and exhaust fans are on. When the indoor flue gas (CO and CO2) concentration exceeds 0.06%, Y4 and Y3 are powered on, Y2 is set as 1, the alarm light is on, and the window exhaust fan is on. When the infrared detection output is 1, Y4 is powered on, Y2 is reset, the window is closed, and the alarm light is on. The human-machine interface of the Android mobile terminal of this system can be directly operated by the user and real-time monitoring data, reflecting the convenience of the design. Therefore, the design of complex home control system is of great significance in the home industry.
