The Design Of Field Crops And Environmental Information Acquisition And Publishing Platform Based On Java Web

In recent years, with the evolution of wireless sensor networks and mobile wireless communications technology, human studies on the application system of field crops and environmental information is in the ascendant, a variety of software and hardware resources provides an effective way to the acquisition of field crops and environmental information. In this paper, by exploiting wireless sensor technology, WEB technology and network technology, we have developed a stable, Java Web-based visualization of field crops environmental information collection and dissemination platform on the basis of the ZigBee wireless sensor networks and GPRS-based communication network hardware. Using the combination of C/S and B/S development model and Java Web technologies system, SQL SERVER 2008 as the database development and management tool, realizing the real-time monitoring and statistical analysis of environmental information in field crops. Using JFreeChart and Highcharts as the two open source reporting techniques to field crop for Visual display of environmental information, and real-time access to field data and statistical analyses in support of agricultural scientific. Agricultural scientists and technicians can make decisions while providing insight to guide agricultural production. This paper conducted the following research areas:(1) Crop information collection:According to field crop information and environmental information real-time monitoring information about two different specific requirements, the use of three different types of sensors. Type I is the normal temperature and humidity sensors, such as air and soil temperature and humidity sensor, this sensor uses a wide range, is the most basic type of sensor. Type II is a high precision smart digital sensors, such as soil lead ions, calcium ion sensor, this type of sensor is introduced from abroad, is more advanced for OTA contents of heavy metals, ammonia and nitrogen contents in soil, PH value and other elements of a full range of monitoring. Type III is a crop body information sensors, such as photosynthesis and so on, these sensors to monitor crops in their rate of photosynthesis, respiration rate, plant SAP flow ontology information. Through the application of three kinds of sensors, a full range of field crops grown were collected information, and soil information and environmental information, perception and acquisition of information for OTA Terminal hardware that has laid a solid foundation.(2)Agricultural information transmission:This paper analyzes various means of information transmission characteristics of the existing collection system of field crops and environmental information, on the advantages and disadvantages of information transmission, practicality, cost, price, and other parameters were analyzed and compared, using a stable and reliable real time and efficient GPRS wireless communication technology, tested the parameter configuration and performance of GPRS DTU, developed data reception center (DSC), enabled remote field crops and environmental sensors and real-time communication capabilities between servers, and received information in the server’s database, provided a stable and reliable data protection for the information dissemination and exhibition at a later stage.(3)Development of platform for data presentation:Through the research and study of the existing domestic and international websites and information platform of agricultural, combined with the popular Java Web development technologies, using pre-collected database of field crops and environmental information, analysis, design and develop a suitable field of agriculture data display platform. Platform for agricultural can be directly accessed by scientists and technicians through the browser, querying environmental information in field crops and through the analysis of information and statistics to complete the guidance to agricultural production.
