摘要

本論文運用Vision公司所生產的VUM9000超高頻射頻辨識模組來實現915 MHz手持式射頻辨識讀取器。主要涉及標準為ISO 18000-6C，包含了EPC Class-1 Generation-2通訊協定、封包格式與基頻編碼方式等等。
在一個完整的射頻辨識系統主要由讀取器與感應器所構成，具備高資料密度、快速讀取速度、良好機器可讀性、不易受灰塵影響和未經允許複製與修改之可能性低等優點。因隨著企業不斷地擴大，在倉儲管理的運作也隨之複雜，若能將RFID技術導入於倉庫管理系統中，將有助於提升倉儲管理的績效。在本論文所探討為產品進行進貨入庫、盤點、揀貨與出貨運輸等作業時，運用內文所設計的手持式射頻辨識讀取裝置，使得產品標籤(Tag)內之記憶體可涵蓋整個倉儲流程的資訊，因此能快速而準確的分類出不同項目，進而提升倉儲管理運作與處理速度，達到產品資訊透明化與管理便利性。
上述射頻辨識系統裝置與倉儲管理流程應用均使用微控器與組合語言來加以實現，最後整合微控器、射頻辨識模組與天線的要點，達成射頻辨識系統的完整性，並應用915 MHz射頻辨識系統在模擬的倉儲環境下實現倉儲管理系統。

This thesis implements a 915 MHz handheld RFID reader using the UHF Vision VUM9000 RFID reader transceiver IC. The major research topics include the ISO 18000-6C standard, EPC Class-1 Generation-2 communication protocol, data packet format, baseband coding, and so on.
An RFID system comprises a reader and a transponder, which finds numerous applications due to its high data density, fast reading speed, good machine readability, no influence by dirt, and low possibility of unauthorized copying/modification. As time goes on, the companies extend their business areas continuously; the operations of the warehouse management will also become more complex than before. Under this circumstance, the RFID technology will be helpful in enhancement of the efficiency if the companies apply this technique to the warehouse management. In this thesis, Implementation of 915 MHz Handheld RFID Reader for Warehouse Management, designed to discuss if the handheld RFID reader mentioned could be applied under the process of storing, inventorying, picking, shipping and transporting, then making the memories of product tag cover entire information of management flow in order to classify more faster and precise the different products, also enhancing system availability and speeding up the search functions to achieve the transparency of product information and ease of management.
The RFID system devices, warehouse management processes and applications above are realized with the aid of a microcontroller and the assembly language, then integrating main points of microcontroller, radio frequency identification module and the antenna to reach the integrity of RFID systems and accomplish the 915 MHz RFID system into warehouse management system eventually by using a stimulated warehouse scenario.
