Design Of Energy Expenditure Detection System Based On Wireless Sensor Networks

With the rapid development of communication, embedded computing and sensortechnology, wireless sensor network (WSN) technologies are getting more and moremature and the use of WSN are becoming increasingly popular in video and trafficmonitoring, air traffic, cars and robot control, intelligent household and industrialautomation and other fields. The development of science and technology for people’slife and work to bring great convenience, at the same time also makes people’sactivity and exercise are greatly reduced, cause health problems such as weak body.But sports is also there is a certain risk, such as excessive movement, muscle strain,the problem such as heart attack, therefore, needs to have certain security monitoringin the process of movement, to be able to correctly judge the health campaigners,prompt and restricting certain sports, etc.The thesis first introduced the development of wireless sensor network, thedevelopment of energy consumption detection system, and ZigBee technology. Onthis basis, the project mainly researched on the research is mainly focused on thedetection terminal (coordinator and router) design, ZigBee network routing protocoland energy consumption of human movement detection algorithm. This project raisedthe overall design of human movement energy detection system, and then, researchand designed the wireless sensor network (WSN) coordinator, router and PCmonitoring system. Two types of network node controller USES CC2530chip, amongthem, the routers by the sensor Module, data transmission Module and Power Module,etc; The software was ported by TI’s ZigBee protocol Z-Stack and using the AODVjrrouting algorithm, added personalized node information, and add the code toimplement corresponding node function. The routers to the movement of dataprocessing analysis, in view of energy consumption detection method based on theaxial acceleration value, gesture recognition using the data feature extraction methodsof GM, send these dates to coordinator by WSN, and display data real-time. Afterreceiving new packets, the coordinator exchange data by USB to PC monitoringsystem. PC monitoring system receives and arranges the human movement of energy consumption data by communication form, and deposited in the backend database,when need to analyze historical data, it is concluded that the students movement andphysical states, this movement is reasonable and healthy advice and other information,so as to realize the purpose of student sunshine sports.The energy consumption detection system in this paper, the coordinator betweenrouters and communication effect is good, greatly improved the problem such as nodeloss, loss of data. The project of PC monitoring system achieved to simple, easy tooperate, easy to use, could monitor the real-time changes of the dates for humanmotion, and could stable operation. The system without complicated wiring, reducingthe point of failure, reducing costs, and having good scalability, lays the foundationfor the further development of the greenhouse monitoring and controlling system, andthere is a wide application prospect and practical value.
