In this paper, we proposed the clothing management system using the smart hanger. Proposed system consists of smart hanger, base module, and server, and the smart hanger consists of MCU, LED, RFID reader, RF chip, ring sensor, and battery. The smart hanger reads the RFID tag attached to the clothes and wirelessly transmitted to the server. The server associated base module communicates with the smart hanger and transmits information to the server. The server manages clothing through the DB, and can display various information through the web page and the smart phone. In order to verify the usefulness of the proposed system, we did experiment with the management system for clothing store and laundry where using a lot of hangers. Performance tests of the smart hanger are applied to check the current consumption and can be predicted the battery life with the proposed low power algorithm. The clothing store management system can be increased sales and convenience of the consumer. The laundry management system can be increased the efficiency of laundry category and convenience of the consumer.

일반적인 소규모 휘발성유기화합물(VOCs:Volatile Organic Compounds) 배출시설인 주유소, 세탁소, 도장시설 등의 환경에서 대기로 배출되는 휘발유 유증기, 세탁용제(솔벤트유) 증기 등을 포집하여 포집된 유증기를 다시 액화처리 과정을 통하여 휘발유, 솔벤트로 재생산하는 기존의 PLC(Programable Logic Control) 방식의 처리과정을 ICT(Information Communication Technology)을 도입하여 보다 효율적이고 안정적인 스마트한 VOCs 액화장치 관리시스템을 개발하고자 한다. 현재 기존의 주유소 휘발유증기액화장치는 타이머와 릴레이 등을 조합하여 냉동 공조 장치로 동작하도록 하고 있다. 이는 단순한 전기제어로 동작하여 관리자가 항시 주의를 요하며 전력소비가 심해 생산량에 비해 손해가 발생하게 되며, 관리자가 원격지에서 생산량과 현 상황을 확인할 방법이 존재하지 않아 항상 관리자가 직접 수기로 기록하게 되어 많은 불편사항이 발생하였다. 본 논문에서 이러한 기존의 시스템을 대부분 유지하고 자동화와 원격 모니터링 시스템을 갖추고 블루투스(bluetooth) 모듈을 이용하여 원격에서 시스템을 관리할 수 있도록 개발하고자 한다.

This paper presents smart laundry management system using wireless Radio Frequnecy Identification (RFID) reader for efficient managing a large amount of laundry and clothing. The proposed system is comprised of wireless RFID hanger, base module connected on PC, and server system. The wireless RFID hanger with RFID reader read RFID tag attached on clothes and transmit tag information using wireless communication. The server system manage customers and his clothing using Database (DB) and display the information on the web page and smart phone devices. Since the proposed system operates with battery, we can evaluate its lifetime to measure current consumption. The designed system can be utilized to manage quantities of clothes and also it will be a good service to improve efficiency of laundry process.

This paper is to automate the intelligent and equipment to recycle the volatile organic compounds in various a gas stations and a laundry, in real life. In addition, based the ZigBee module and TCP/IP communications on ICT technologies, it's propose an integrated management system to monitor and manage an liquid at a remote location.Furthermore, it's propose a service model that can be freely managed from a remote location based on the app on android. In this paper, we present a communication protocol of the bridge modules and a liquefier of intelligent control system based ZigBee and MCU(Micro Controller Unit). Through the development of smart app based android mobile services in an integrated management system, it's represent for liquefier to a DB server for remote management(MS SQL 2012) and a web server (OS: Windows 2008).
