꿀벌 생육환경 정밀 모니터링을 위한 실시간 데이터 처리 시스템 연구

Abstract

The precision apiculture based on ubiquitous sensor net work technology is a system that can collect the within-hive environment controlled by honey bees. After analyzed the elements of within-hive environmental factors necessary for the beekeeping and selected appropriate sensors, we developed a sensor board which is installed inside the beehive through this sensor and collects the signal data of growth environment. The Signal data collected from various sensor boards in each beehives is transmitted to the communication board through a wireless communication network capable of 1: N communication. The communication board converts the collected data into a data table optimized for DB storage and transmits it to the server through the TCP / IP communication protocol. The server stores the transferred data in the DB and provides a web server based user interface for processing the DB access request of users. By connecting to the bee-portal site, the user can monitor the within-hive environment with personal computer or smart-phone. However, sensor board or communication board may fail due to various reasons such as rain, wind, lightning, insect or animal attack. For this reason, data transfer from the communication board to the server fails. And some data can be lost. To solve the problem of data loss, we applied several interpolation methods to the data loss. We have simulated interpolation of data loss in the most interpolated way. As a result, interpolation of data loss is completed. Furthermore, we apply this result to a real-time bee monitoring system and apply it to interpolate data loss.
