| 摘要: | 傳統上，森林資源的管理與保育方式，仍以人工的方式到現場去巡邏檢查、蒐集資料，再將資料帶回到後端的工作站，提供工作站的管理人員更新數據。但此作法需要巡檢人員到現場，因此顯得浪費人力與時間。最主要的是，由於後端的工作人員無法立即得知現場狀況，故也無法在林木被盜伐時，立即做出回應。若把RFID的辨識技術導入到此種應用中，將可以簡化了巡檢人員的工作流程與時間。 因此提出以RFID的辨識技術為基礎架構，並建構一個RFID資訊服務平台，讓使用者可以於電腦前，透過網路直接監控遠端的系統；另一方面，前端的巡檢人員，只要具備有支援WiFi無線上網的PDA或者手機，甚至是小型電腦，就可以到現場執行巡檢任務，而非是採用專屬的攜帶式讀取器。 本研究將待監測環境劃分成許多區域，每個區域包含了一個讀取器與數個貼附在待測物上之標籤，每個讀取器均以一台無線網路存取點連接，讓巡檢人員可以透過無線網路加入此系統。另外，在系統佈建初期，巡檢人員會先貼附標籤於所有待測物上，然後讓後端工作站的工作人員，選擇最佳的讀取器安置區域，試圖用最少量的讀取器達到最佳的讀取效果。 系統的規劃分成三大部份，包含了RFID硬體設備、後端工作站伺服器與前端巡檢人員所使用的軟體平台。前端RFID為本系統之基礎，用於辨識各個物件。後端工作站伺服器作為前端RFID的資料接收站與屬性資料庫。前端巡檢人員則可透過網路從工作站中下載對應區域的底圖、標籤屬性與任務等。本研究之重點為設計並實現給巡檢人員所使用的軟體平台，以嵌入式Linux作業系統作為目標的作業環境，並提供地圖顯示功能、GPS服務、RFID裝置資訊管理、巡檢任務管理以及後端伺服器同步之數位巡檢系統。 Traditionally, forestry and resource conservation needs staff member to inspect and collect data personally, and then bring the information back to workstation for updating database. However, the traditional practices needs staff member to inspect personally, it is waste of manpower and time. Also, most important of all, the staff member in the workstation cannot reflect on-the-spot, if the tree was felled illegally. Moreover, it simplifies workflow by introducing the RFID technology. Therefore, construct a RFID Information Service Platform which based on the RFID technology, allows user to stay in the office and monitor the remote forest over the network. On the other hand, the inspection staff member can easily add to the system by using PDA, cell phone or even notebook which supports WiFi wireless network technology, instead of using specific portable reader. In this study, the forest divided into many regions, each region contains a reader and many RFID tags. Also, each reader connects a wireless access point which allows inspection staff member to adjust the system through wireless network. The primary stages of system construction, all the RFID tags will be attached with location information. Thus, staff member from workstation will be able to report information includes the best location of each reader, in order to get the best results. The system contains three components, including RFID hardware device, back-end server and the mobile software platform for inspection staff. RFID hardware device is the fundamental of this system for identification of various objects. The server is a repository of RFID system which keeps the attribute of all tags. Inspection staff member can download the attribute of tag and reader and the maps of current area. The main goal of this paper is design and implement software platform for inspection staff member, and it is based on the embedded Linux. The mobile platform provides function such as display map, GPS service, RFID device management, task management and synchronization with server. |
