Abstract:	RFID技術的應用以及電腦科技及網際網路的日益發展，近年來已更多元化發展，並且已有許多成熟的商業化產品被推出，而傳統上的彈藥管理作業，也可嘗試利用此一先進的技術加以改善，來精簡作業流程、改善管理效益及強化安全管理作為。本研究彙整國內彈藥管理相關文獻，透過對這些文獻的探討，瞭解國內在彈藥管理作業的流程、所遇到的窒礙因素，以及已提出之相關改善作為，再分析此一作業流程與RFID技術之間的結合方式，最後我們發展出一套適合現行彈藥管理作業的UHF頻段RFID系統。接著，我們在系統建置完成後，設計幾個不同的部署方式來對系統進行模擬實驗，實驗內容包含彈藥箱數量增減、標籤讀取率、標籤讀取速度、天線距離遠近、天線部署角度等，經由上述實驗結果，獲得標籤讀取率及讀取速率在不同部署方式的變化曲線，我們再將所獲得的實驗數據，回饋並修正RFID彈藥管理系統之參數，使本系統對於各標籤之讀取率及讀取速度的性能達到最佳化。此外，我們觀察到有些標籤在讀取速率極度不佳的時候，對於系統在未經允許之彈藥出庫判斷上會造成失誤，而產生異常離架紀錄，本研究提出一個可調整的參數-異常離架敏感度，使本系統能夠更準確地監控彈藥庫的安全狀況。In recent years, the application of the RFID technology has been more diversified, along with the computer science and Internet technology growing, and there are many mature commercial products being developed. The traditional ammunition management practices can try to use this advanced technology, to streamline processes, enhance management efficiency and strengthen security management. This study search domestic literatures about the ammunition management, and through these literatures we can understand current operating procedures of ammunition management and its predicament and improve way, and analyzed the way of combination between current operations and the RFID technology. Finally this study designs a RFID system with UHF-band for the current operating procedures of ammunition management. The study designs several different kinds of methods, and a set of simulation test including increasing ammunition boxes, RFID tag’s read rate, RFID tag’s read speed(per second), distance of antenna, and angle of antenna…etc., to evaluate the system performance. Through these tests, we can obtain the curves of tag’s read rate and read velocity in different deployment methods. To optimize the system performance in tag’s reading rate and reading velocity; this study uses the output data to feedback and modifies the system parameters. In addition, it observes that system may judge wrong in taking out the ammunition boxes without permission when the tag’s reading velocity is very low. The study designs a system parameter that can be adjusted, called the “Sensitivity of off the tray unusually”, it will let the system can be more accurately to monitor the safety state of the ammunition depot.
