Study on an agricultural environment monitoring server system using Wireless Sensor Networks.

This paper proposes an agricultural environment monitoring server system for monitoring information concerning an outdoors agricultural production environment utilizing Wireless Sensor Network (WSN) technology. The proposed agricultural environment monitoring server system collects environmental and soil information on the outdoors through WSN-based environmental and soil sensors, collects image information through CCTVs, and collects location information using GPS modules. This collected information is converted into a database through the agricultural environment monitoring server consisting of a sensor manager, which manages information collected from the WSN sensors, an image information manager, which manages image information collected from CCTVs, and a GPS manager, which processes location information of the agricultural environment monitoring server system, and provides it to producers. In addition, a solar cell-based power supply is implemented for the server system so that it could be used in agricultural environments with insufficient power infrastructure. This agricultural environment monitoring server system could even monitor the environmental information on the outdoors remotely, and it could be expected that the use of such a system could contribute to increasing crop yields and improving quality in the agricultural field by supporting the decision making of crop producers through analysis of the collected information.

Study of the Ubiquitous Hog Farm System Using Wireless Sensor Networks for Environmental Monitoring and Facilities Control

Many hog farmers are now suffering from high pig mortality rates due to various wasting diseases and increased breeding costs, etc. It is therefore necessary for hog farms to implement systematic and scientific pig production technology to increase productivity and produce high quality pork in order to solve these problems. In this study, we describe such a technology by suggesting a ubiquitous hog farm system which applies WSN (Wireless Sensor Network) technology to the pig industry. We suggest that a WSN and CCTV (Closed-circuit television) should be installed on hog farms to collect environmental and image information which shall then help producers not only in monitoring the hog farm via the Web from outside the farm, but also facilitate the control of hog farm facilities in remote locations. In addition, facilities can be automatically controlled based on breeding environment parameters which are already set up and a SMS notice service to notify of deviations shall provide users with convenience. Hog farmers may increase production and improve pork quality through this ubiquitous hog farm system and prepare a database with information collected from environmental factors and the hog farm control devices, which is expected to provide information needed to design and implement suitable control strategies for hog farm operation.

A Wireless Sensor Network-Based Ubiquitous Paprika Growth Management System

Wireless Sensor Network (WSN) technology can facilitate advances in productivity, safety and human quality of life through its applications in various industries. In particular, the application of WSN technology to the agricultural area, which is labor-intensive compared to other industries, and in addition is typically lacking in IT technology applications, adds value and can increase the agricultural productivity. This study attempts to establish a ubiquitous agricultural environment and improve the productivity of farms that grow paprika by suggesting a ‘Ubiquitous Paprika Greenhouse Management System’ using WSN technology. The proposed system can collect and monitor information related to the growth environment of crops outside and inside paprika greenhouses by installing WSN sensors and monitoring images captured by CCTV cameras. In addition, the system provides a paprika greenhouse environment control facility for manual and automatic control from a distance, improves the convenience and productivity of users, and facilitates an optimized environment to grow paprika based on the growth environment data acquired by operating the system.

Agricultural Production System Based on IoT

There has been much research and various attempts to apply new IoT technology to agricultural areas. However, IoT for the agriculture should be considered differently against the same areas such as industrial, logistics. This paper presents the IoT-based agricultural production system for stabilizing supply and demand of agricultural products while developing the environment sensors and prediction system for the growth and production amount of crops by gathering its environmental information. Currently, the demand by consumption of agricultural products could be predicted quantitatively, however, the variation of harvest and production by the change of farms cultivated area, weather change, disease and insect damage etc. could not be predicted, so that the supply and demand of agricultural products has not been controlled properly. To overcome it, this paper designed the IoT-based monitoring system to analyze crop environment, and the method to improve the efficiency of decision making by analyzing harvest statistics. Therefore, this paper developed the decision support system to forecast agricultural production using IoT sensors. This system was also a unified system that supports the processes sowing seeds through selling agricultural products to consumers. 3 Corresponding author The IoT-based agricultural production system through correlation analysis between the crop statistical information and agricultural environment information has enhanced the ability of farmers, researchers, and government officials to analyze current conditions and predict future harvest. Additionally, agricultural products quality can be improved because farmers observe whole cycle from seeding to selling using this IoT-based decision support system.

Design of integrated control system for preventing the spread of livestock diseases

This study is to develop an integrated control system for preventing the spread of livestock diseases including the food-and-mouth disease (FMD) that has recently been prevalent in South Korea. The system is expected to collect the information and images of livestock and raising facilities by use of radiofrequency identification/ubiquitous sensor network (RFID/USN) and an image processor. Additionally given the fact that livestock diseases may be prevalent, the system is aimed at tracking vehicles carrying feedstuff, milk and excretions by use of radiofrequency identification/global positioning system (RFID/GPS). The collected data are stored in an integrated database (IDB). In particular, the system enables prompt actions against abnormalities that occur in livestock or raising facilities.

Design and Implementation of Wireless Sensor Networks Based Paprika Green House System

This research paper suggests the ‘Paprika green house system’ (PGHS), which collects paprika growth information and greenhouse information to control the paprika growth at optimum condition. The temperature variation range of domestic paprika cultivation facilities are relatively quite big and the facility internal is kept at relatively dry condition. In addition, the concentration of CO2 is not uniform, giving bad impact on the growth of paprika. In order to cope with these issues, the ‘Paprika green house system’ (PGHS) based on wireless technology was designed and implemented for the paprika cultivating farmers. The system provides with the ‘growth environment monitoring service’, which is monitoring the paprika growth environment data using sensors measuring temperature, humidity, illuminance, leaf wetness and fruit condition, the ‘artificial light-source control service’, which is installed to improve the energy efficiency inside greenhouse, and ‘growth environment control service’, controlling the greenhouse by analyzing and processing of collected data.

The proposed system collects information on necessary environmental factors for plants growth, nutrient solution, etc. through sensors installed in a plant factory and infers contextual information through the ontology based on the collected data to provide corresponding appropriate services to users. In addition, this system supports various application platforms such as web PDA, smart phones, etc. so that users can access its service on the plant factory anywhere and anytime.

A Study on the RFID/USN Integrated Middleware for Effective Event Processing in Ubiquitous Livestock Barn

The RFID/USN technology is one of the important technologies to implement the ubiquitous society, and it could make many changes in the existing agricultural environment including livestock rearing, cultivation and harvest of agricultural products if such a RFID/USN technology is applied to the agricultural sector. In particular, for livestock barns, the RFID/USN technology has been applied to manage livestock’s history and monitor environments of livestock barns, and it is secured the increase of productivity and the transparency of distribution channels through it. In the case of livestock barn systems applying such a RFID/USN technology, an integrated RFID/USN middleware technology is required to provide a combined service through effective processing of generated data and organic connections between application services because it should be processed an enormous amount of data collected via the RFID/USN in real-time. This paper would propose an integrated RFID/USN middleware for implementing a combined service by efficiently processing data collected from the RFID, which is used to identify livestock, and the USN, which is used to monitor livestock barn’s environment, and by organically connecting with data. The proposed middleware has features to reduce application’s load and provide data requested by applications by filtering data generated in real-time in the RFID and USN environment applied to livestock barns.
