Research On Monitoring System Of Cucumbers Diseases In Greenhouse Based On Wireless Sensor Network

Disease monitoring of greenhouse helped to improve crop production, crop quality and economic benefits, while protecting the ecological environment. Traditional Greenhouse Monitoring System used more the wired connection, there are complicated wiring, cost, maintenance difficulties, not high precision. micro computer control and wireless communication technology provides a new way of thinking for greenhouse crop disease monitoring .In this paper, the monitoring of diseases of greenhouse cucumber researched and designed the greenhouse crop diseases monitoring system based on wireless sensor networks.Because of geographical and environmental differences, the incidence of pests of greenhouse crops is very different, but in addition to its own crop factors, cucumber, environmental factors play important roles, by summarizing the status of the diseases occurrence and characteristics of cucumber diseases, Ecological factors include temperature, humidity, light and soil PH value and other factors. Analysis demand on disease monitoring of wireless sensor network applications to greenhouse. The proposed network monitoring platform single-chip JN5139 single chip as the core, the greenhouse disease system based on Zigbee wireless sensor networks.System was developed Zigbee nodes by a hardware platform JN5139, node-driven STH11 sensors collected temperature and humidity inside the greenhouse. Then the data collected from ecological factors send to multi-hop cluster node, the integration of data and simple analysis, and through the serial port to monitor data center PC. Quickly through the API functions JN5139 Zigbee network, the system used a mesh topology, the design of wireless sensor nodes and networking communication mechanism, so achieved the optimal routing node transmission channels and multi-hop way to upload. Increase the network's data security and network dynamics procedures to ensure the stability and security of the network. Monitoring Center PC provided ecological factor data display, data trends and historical data inquiries.Development of experimental tests show that the system is simple and reliable, flexible networking, transmission distance, the greenhouse can be effective and accurate monitoring of the environmental factors. Improve the monitoring of greenhouse automation.
