Abstract

To protect the students from food poisoning, in this paper, it is proposed that the Smart HACCP system which based with WCDMA-LTE to monitoring the temperature and humidity of a freezer, a heating cabinet and kitchen instruments at the elementary, junior and high school. After gathering the data, It is compared with a standard food poisoning index to provide more safe food reserves from the server. Then the server send a index to the terminal which is installed in a kitchen at any school to show the current environment. It is need an WCDMA-LTE terminal to realize smart HACCP system that is proposed from this paper. So, the proposed WCDMA-LTE terminal is designed with using a LTE modem included a 424 MHz wireless modem and a bluetooth 4.0 modem to communicate with other terminals. It can be use the monitoring system of a plastic greenhouse or remotely environment control system.

본 논문에서는 초 중 고등학교의 급식과 관련하여 학생들의 식중독 사고를 예방하기 위해 급식소의 냉 온장고 및 각종 주방 기기의 온도와 습도를 모니터링하여 WCDMA-LTE 망을 이용하는 스마트 HACCP 시스템을 제안한다. 단말기로부터 수집된 데이터는 특정서버로 전송되며 더욱 안전한 식품을 제공하기위해 식중독지수와 비교된 후, 단말기가 설치된 장소의 식중독지수를 LCD화면에 표시하도록 한다. 이러한 시스템을 구현하는데 있어 주요 요소가 WCDMA-LTE 망 기반의 온습도 측정 및 모니터링 시스템 전용 단말기이다. 따라서 본 논문에서는 다른 단말기와 상호 통신이 가능하도록 424 MHz 및 블루투스 4.0 무선모뎀을 포함한 LTE 단말기를 설계하고 구현하였다. 향후 본 시스템은 비닐하우스의 온도감시 시스템 또는 원격 환경감시 시스템으로의 적용이 가능하다.
