Research On Intelligent Building Control System Based On Raspberry Pi

With the development of society,people's living standards are improved and energy consumption is increased,especially in large buildings.A large amount of energy consumption has led to the destruction of the ecological environment.In this paper,it is proposed that the advanced intelligent building control system can not only save resources and protect the environment,but also improve people's living standard.With the further improvement of the embedded device intelligence and the rapid development of the Internet of things,the intelligent controller has gradually become the core control device of the embedded device,slowly developing from some home appliances,living tools to the Internet of things,smart home.Smart cities and other new areas.This paper studies an intelligent building control and system design based on Raspberry Pi.The hardware design of the control system consists of two parts: the main board of the controller and the expansion board of the controller.The controller motherboard is divided into two parts: the core board and the equipment board.The core board is the core of the controller,can complete independent calculation and has rich peripheral interface.The equipment board mainly realizes the expansion of the module,the design of the AD/DA conversion module,the design of the light input /output module and the design of the RS485 communication module,etc.The main function of the controller expansion board is to further the interface Classification expansion.The software part of the intelligent building controller control system is mainly developed under the Linux operating system environment.Based on the designed hardware,the driver of each hardware module is developed.The Modbus communication between the controller motherboard and the extended version of the controller and the WiFi wireless communication between the controller motherboard and the controller motherboard are realized.This topic is a new generation of intelligent building control system,to a certain extent,it has also promoted the development of intelligent building control system in China,at the same time,it is also of great significance to the development of intelligent building.
