Research On WSN-based Technology Of Environment Monitoring System Of Intelligent Building

Intelligent buildings are “With buildings as a platform,it has information facility systems,information application systems,construction equipment management systems,public safety systems,etc.It integrates structure,systems,services,management and their optimized combination to provide people with safety,Efficient,convenient,energy-saving,environmentally friendly and healthy building environment”.The environmental monitoring system of the intelligent building is an important subsystem of the intelligent building.It provides all-weather monitoring of the internal and external environments of the building,provides data support for environmental abnormality prediction,energy saving and consumption reduction,safety management and control,convenient life,etc.It effectively protect the building and the life and property safety of internal staff.Therefore,this has always been a focus and research hotspot in the field of modern architecture and information and communication.This subject intends to construct an intelligent building environment monitoring system based on wireless sensor network,and study the main key technologies of the system,so as to provide technical support for the engineering practice of the system.The main work is as follows:1.This paper studies the energy-saving routing algorithm of wireless sensor network in intelligent building environment monitoring system.Based on the low-power adaptive clustering routing algorithm,combined with the idea of geographic adaptive fidelity algorithm to divide the target area into many virtual cells,an improved algorithm is proposed.The algorithm optimizes the low-power adaptive clustering routing algorithm by improving the clustering method,cluster head election conditions,and cluster first round routing conditions,and verifies the feasibility of the algorithm through simulation and comparative experiments.2.This paper constructs a wireless sensor network system based on ZigBee protocol,which is suitable for the functional requirements of intelligent building environment monitoring system.Each sensor node is networked through ZigBee technology,and the coordinator collects the data of each sensor node,and transmits the data to the monitoring terminal after fusion processing.Users can monitor and analyze the building environment information in real time through the monitoring terminal.3.Based on CC2530 chip as the main control chip,a wireless sensor network node is designed to meet the functional requirements of intelligent building environment monitoring system.The node integrates flame sensor,temperature and humidity sensor,human body detection sensor,air quality sensor and other sensors,as well as sound and light warning function.It can collect a variety of information of the building environment at the same time,and preprocess the data at this node to reduce data transmission overhead.In case of emergency,it can provide sound and light warning.The node can use battery or 220 V power supply according to the needs.4.With the Z-Stack protocol stack as the core,the software realizes the networking,collection and data transmission of sensor nodes.Based on the Visual Studio 2013 development platform,the user terminal platform of the intelligent building environment monitoring system is constructed to realize the functions of monitoring data collection,real-time display and abnormal alarm,and complete the main function test.
