RFID 옷걸이와 무선 센서 네트워크를 기반으로 하는 스마트 세탁소 시스템의 설계 = The Design of Smart Laundry System Based on the RFID Hanger and Wireless Sensor Network

다국어 초록 (Multilingual Abstract)

Nowadays, high quality service in industrials is required. Conventional laundry system needs many people in order to operate, sometimes mistakes happen by human.
Therefore the cost to operate the system is high and poor quality service.
In this thesis, I proposed Smart Laundry System (SLS), in order to provide high services, low operation costs and better monitoring. The proposed system consists of RFID tag, wireless RFID hanger and MFC software. The low power algorithm was proposed, the low power system configures the Network with the RF communication module that turn on/off periodically, power consumption less than operating the module all the time without it toggles. Our system was developed as a web application. Therefore, customer can check their cloth status through web page or Smartphone devices. RFID reader was designed on hanger to make our system enables reliable running effectively.
In order to test the system, some results on the performance of an implementation are presented.
