    • 　　在即時監控系統中，被監控端透過無線的行動通訊系統與監控端建立TCP/IP的連結以傳遞數據，被監控端使用成本價格低AT89S51微處理器作控制通訊連線的建立與數據的傳遞，監控端為一架設於Internet上的伺服器，接收被監控端的資料、記錄並將該資料顯示於監控軟體上，另外亦可藉由以建立的通訊連線對被監控端傳輸控制訊號。

    　　本論文將呈現設計及開發手持式之監控系統的心路歷程。手執式監控系統的設計包括了GPRS連線通訊初始化、微處理器韌體設計、外部資料輸入的通訊協之訂定、充電電路設計等。經過各種的測試與改進，使用小型的鋰電池作為電源供應的電路、可長時間運作以提供服務的系統終於在本研究中完成。系統穩定度、可靠度及其重要功能的測試亦在本研究中被驗證。

    　In real time surveillance system, there is an urgent demand of TCP/IP capability to connect client data into server integration through mobile communication system. Under such demand, the circuit design is simplified and implemented using 8051 MCU with tri-state gate control to process mobile data, to transmit via communication device, to collect and display mobile data by an Internet server, and to offer a full function of surveillance capability to mobile users. This thesis presents a handy surveillance system design and implementation for e-care applications. The design of handy client system includes GPRS data communication, the firmware design of MCU, the protocol design of digital input, energy management, and etc. Through design process, the implemented system is miniaturized into battery-supply for long lasting operation. Tests have been carried out to verify the important functions with reliability and stability.
