隨著網際網路的發達和頻寛世代的來臨以及e-Learning的盛行，利用網際網路來實現遠距教學已經非常普遍。遠距教學不但可以增加硬體設備的使用率，還可以降低實驗室的成本。實際的操作經驗對學生的學習來說，是非常重要的一部份。由於許多硬體實驗設備並不提供遠端控制的功能。再加上部份設備價格較高，因此通常一套硬體實驗設備必須由多位學生共同使用，而且限制學生只能在上課時間使用並且無法外借。基於這些原因，我們提出一套遠端實驗室架構而且實作出來。我們的遠端實驗室主要是利用虛擬串列埠技術來搭配實驗室內的實驗設備，提供具透明化且相同操作界面讓學生在家裡亦可透過遠端實驗室來操作學校設備，而且感覺如同在學校操作一樣。讓學生可以不受時間和空間的限制使用實驗室設備，進而提高設備的使用率。並且提供了彈性化的控制環境，可以依照需求的不同而選擇是否要啟用預約功能。我們也提供了多人同時連線、讓同一組的學生可以同時看到操作的情形並且可以隨時把控制權交換給其它同學輪流使用。這些情境和在學校實驗室的操作過程是相同且一致的。本系統同時可以支援透過serial port介面操控的不同實驗平台。為了驗證系統的可行性，我們對逢甲大學資訊系的39位學生進行系統測試，實驗結果證實透過遠距實驗方式教學達到團隊合作功能並且可以降低實驗設備的成本，增加學生對學習的興趣，提高硬體設備的使用率。

With the progress of the Internet, the advance of network technology and the population of e-Learning, using the Internet to realize distance laboratory is very prevalence because of the characteristic of the Internet can access anytime and anywhere. Taking advantages of e-Learning technology, distance laboratories can be used not only to increases the utilization rate of experimental devices, but also can reduce the construction cost for a laboratory. However, while distance learning often fails to present such realistic interface, traditional devices rarely support remote control function, thus unsuitable for constructing distance laboratory. Based on these reasons, in this work, a transparent and ubiquitous access platform for distance laboratory is designed and implemented. We proposed a remote laboratory framework supports for various hardware devices and without any additional modification, so students can remotely access the platform without much difference with tradition laboratory. In addition, group-based learning is made possible by providing multi-users and observers. In order to demonstrate the feasibility of our distance laboratory, experiments are conducted in a 40-student course for network management. The experiment results demonstrate that the proposed framework indeed suitable for embedded education, and networking devices. It can increase the utilization of hardware device; reduce the cost of conducting the laboratories, thus an effective approach to enhance the interest of learning.
