近幾年無線射頻辨識系統成為一個熱門話題,RFID之創新應用被譽為二十一世紀最重要的技術發展之一。近年來手持式裝置已成當紅的產品,並結合最新的無線通訊技術,將能大幅提昇企業的營運績效與競爭能力。 本研究結合無線射頻辨識系統與手持裝置之設備,設計一套產品安全監控與整合服務系統,店家亦可隨時監控展示商品。利用本系統可讓客人在最短的時間得到展示商品的資訊。當中控系統發現商品有狀況時,透過無線網路的傳輸,立即發出警示訊息到監控人員的手持裝置中,進行後續處理動作。此外,在商店要進行盤點工作時,可即時同步中控系統與手持裝置上之資訊,以簡化盤點工作流程。本論文利用RFID能夠快速讀取的優點來設計本商品監控系統,當商品遭到失竊時,系統立即送出警示訊息,經由實驗結果得知,警示訊息傳送至店家及監控人員所花費的時間都在極短時間內(少於10毫秒),針對多樣商品失竊情況下,系統也能夠在1秒內比對物品與送出警示訊息。因此,比起一般店家親自起身處理意外事件相對有效率,也能夠準確通報商品遺失的種類與數量。本研究結果驗證在商品監控上導入RFID技術之可行性。
RFID and handheld devices have become hot issues in recent years. The application and innovation of RFID have been regarded as one of the most important expanding technologies in the 21 century. The handheld devices can promote trading and competitiveness for an industry when they are combined with the latest wireless communication technology. This research designs a product surveillance system which integrates the RFID and handheld device. The store can do commerce fast and display the products while guests can trade and get commodity information on hand. The surveillance system reports the related information to personnel's handheld device immediately whenever a burglary is detected. Besides, the proposed system can be applied to supervise property inventory. Based on the experimental results, an alarm signal can be transmitted to store and personnel's handheld device in a short time (less than 10ms). Even for multiple objects burglary the detection signal is transmitted within 1s. Therefore, the proposed system is not only more effective in handling burglary than the shop owners themselves but also can accurately identify the types and quantities of burglary products. This verifies the feasibility of the RFID technology in designing the product surveillance system.
