Research Of Farmland Environment Parameter Monitoring System Based On The Internet Of Things

In recent years, agricultural Internet of Things has been rapid development and widely use, this promotes agricultural production is gradually toward information technology, automation and intelligent direction from traditional agriculture. In the process of agricultural production, a variety of natural factors such as temperature, humidity, the CO2 concentration, moisture and other elements jointly affect the growth of crops. Traditional agricultural managing the environmental parameters by human perception, such an extensive management, unable to meet the accuracy requirements. To achieve the intelligent management, the establishment of a reliable, practical, long-term remote monitoring farmland environmental monitoring system, can effectively reduce the operating costs of agricultural, improve production efficiency.In this paper, combined ZigBee technology with ARM technology design agricultural environment monitoring system, achieve remote monitoring and management of farmland environment environment parameters. Local users can also take advantage of on-site monitoring center PC to queries farmland environmental information of the region. In the PC internal, is running a stand-alone monitoring software which is developed based on VC ++ 6.0, can meet the user's functional requirement of environmental information real-time monitoring, dynamic analysis, historical inquiry, abnormal early warning. Major research is as follows:(1)Based on agricultural Internet of Things architecture, the designed farmland environment parameters monitoring system could supports TCP/IP network, ZigBee network and 3G mobile network at the same time.(2)Designed system hardware platform based on main chip S3C2440 microprocessor, CC2530, radio frequency chip CC2591 and sensors.(3)Based on the hardware platform, designed and implemented ZigBee wireless sensor network software program and embedded coordinator gateway web server software program.(4)Designed the site monitoring PC subsystem software which supports MySQL database, with data storage, real-time monitoring, dynamic analysis, historical inquiry, abnormal warning functions.This system has a good interactive interface, from a functional point of view, the system can work normally stable, real-time and accurate environmental information collected in the field and to achieve real-time remote monitoring and information management.
