Design and Realization of Organic Viticulture Monitoring System Based on WSN

Abstract

According to the demands of organic viticulture for small environment regulation and management automation, a grape production monitoring system based on wireless sensor networks (WSN for short) was designed, so as to solve the low management automation level, great workload and other problems that exist in traditional viticulture. The system includes a WSN and a planting management-oriented viticulture management system. The WSN consists of twelve environment monitoring nodes equipped with 168 sensors and 12 video capture cards, a sink node and a monitoring center. And it is also free to customize the functions of acquisition, processing, transmission and storage the data, such as soil moisture, soil temperature, air temperature and humidity, rainfall, solar radiation, wind direction, wind speed and so on. The communication between two nodes follows ZigBee protocol. GPRS is used to realize the communication between sink node and monitoring center. Production data collection and analysis, farming management, production decision, insect pest and disease warming are also achieved through GPRS. An experiment on data package transfer rate in grape veraison and mature stages is carried out. Six out of ten sensor nodes have transfer accuracy above 90%, and two below 35%. The reason is that the solar power supply circuit of one node has excessive energy consumption, and deployment location of the other node is influenced by environment which leads to the network instability. Through analysis, results can be got that the power supply and network environment are important factors for performance of WSN in the fields. The design and development of this viticulture monitoring system provide an effective tool for the production information monitoring and analysis decision of organic vineyard.
