The design of the PLC control system in the bathroom

ABSTRACT

This topic mainly comes from the in-depth understanding of the research and development trend of modern intelligent home control technology. With the progress of science and technology and the improvement of people's living standards, the intelligent home control system has gradually become the new favorite of modern families, among which the intelligent toilet control system, as an important part of the intelligent home, has a broad market prospect and application value. The design of intelligent toilet control system based on PLC (programmable logic controller) aims to improve the convenience, comfort and energy saving of toilet through advanced control technology and automation equipment, so as to bring better life experience for users.

With the rapid development of intelligent building and smart home, intelligent toilet as an important part of the smart home, the design and implementation of its control system is particularly important. This paper presents a smart toilet control system design scheme based on Siemens PLC (programmable logic controller). Through the integration and intelligent control of each equipment in the toilet, the water saving, energy saving, automation and humanized control of the toilet are realized. The paper first analyzes the requirements of intelligent toilet control system, and then expounds the hardware and software design of control system based on Siemens PLC, including the schematic of PLC selection, peripheral circuit design, trapezoidal id writing and CAD software drawing. Finally, the feasibility and effectiveness of the control system are verified by experiments.
