基于无线传感器网络的葡萄栽培环境监测系统
Wireless sensor network-based viticulture environmental monitoring system
摘要
Abstract
In order to realize the key environmental parameters in viticulture to be monitored and re-duce the labor intensity of agricultural workers in Southern China,a monitoring system is put forward with combination of the layered wireless sensor network (WSN)and Wi-Fi technique.The CC2530 wireless transmitter chip is used in the system as the core to construct wireless data acquisition nodes, the corresponding hardware design is carried out and a real-time collection is completed for the key en-vironmental parameters,such as temperature and humidity of air and soil,CO2 content and so on.In order to locate network nodes,a network structure is adopted based on the virtual network cells,fur-ther the cluster head election mechanism for the cells is optimized and the multihop transmission of cluster head is achieved;the error detection and correction mechanism are utilized as well.Compared with the traditional LEACH -C clustering algorithm,the improved algorithm has a nearly 22% en-hanced network energy efficiency.The system can monitor a wide range of land in viticulture because multiple assess points are allowable in Wi-Fi technique,also it can retransmit data automatically once any errors occur.This PC monitoring system is easily operated and can monitor any changes in the pa-rameters in grape growth stages real-timely.Importantly,it can trigger an error alarm and indicate ex-pected operations according to the expert experience database implemented.It is shown that the system is reliable in operation and can satisfy the needs of viticulture management.关键词
