Study On Air-conditioning Monitoring And Management System Based On WiFi

With the development of economy and science and technology,air-conditioning has become a must-have item for households and the use of air-conditioners in public buildings is getting higher and higher.Basically all public buildings are equipped with split air-conditioners or Central air conditioning.However,some issues along the way cannot be ignored.For example,in some vacations,there is no air-conditioning in the office buildings,and the cost of air-conditioning electricity is used.The abnormality in the electrical power used in air-conditioning causes an increase in failures and hidden dangers.Therefore,this article designed a WiFi-based air-conditioning monitoring and management system for this type of phenomenon.Without changing the original layout of the room,the wireless sensor technology and network communication technology that are popular today can be used to complete air-conditioning for each room.Remote monitoring and management.The system not only realizes the effective control and management of electric energy and eliminates the waste of electric energy,but also facilitates the management of the building to timely find the faults and hidden troubles in the integrated management of the air conditioning,so that people can use the air conditioner more efficiently and more conveniently.The WiFi-based air-conditioning management system designed in this thesis includes two kinds of air-conditioning controllers,split-air-conditioning controllers and central air-conditioning controllers,which receive host computer instructions and gateways that send instructions to the lower two controllers.Each module communicates with the corresponding gateway through the WiFi module.Several gateways on each floor access the router on each floor through Ethernet.The router accesses the shaft in the building and sends the information to the upper computer.in.The controller mainly completes the monitoring of the power and power of the air-conditioning appliances,realizes the management of the air-conditioning switch,and receives control commands from the gateway.The gateway mainly receives instructions from the host computer to send it to the corresponding controller,and receives feedback information from the controller.This paper mainly completed the following work:(1)Overall system design,description of the system’s function and structure,design of the system’s functional block diagram and network topology.(2)The hardware design of the system completes the component selection of each module,the design of the schematic diagram,and the design of the PCB.(3)System software design,completed the software design of the two air-conditioning controllers and gateways,the design of system working methods and the design of system communication protocols.(4)The system’s network test,the bottom of the two air-conditioning controllers and gateway networking,its communication effects were tested to test its packet loss rate and the implementation of the instructions.The test results show that the WiFi-based air-conditioning monitoring and management system designed in this paper is quick and responsive,precise and timely,and finally installed to the site to meet the user’s requirements.
