近年來科技日新月異，可以看到許多物聯網與遊戲引擎等技術應用於工程領域中，而較少運用於軌道場域。因此本研究欲結合以上技術建立軌道狀態監測系統與管理互動平台，提出應用於軌道監測的初步架構，如此希望能提高軌道養護範圍與管理效率。
考量經濟性，本研究主要使用Arduino微控器連接相關感測元件，製作出一套低成本且輕量化的監測示範模組，供未來廣泛佈設，用於監測道碴軌道中列車通過產生的振動加速度、動態橫向阻力以及鋼軌應變等狀態。監測模組使用無線傳輸方式將數據回傳，並比較了XBee與Cat M1兩種低功耗傳輸模組的特性與效果。
研究以新左營站南端地下化之出土段做為監測地點，觀察該地點長時間的軌道狀態。並從自強、普悠瑪與區間車各挑選一班車，監測近一個月所產生的數據。研究發現三班車動態橫向阻力皆有微幅上升趨勢，而振動加速度則是普悠瑪呈下降趨勢，推測分別受石碴緊實程度與車速影響。此外，因自強號是動力集中式車型，因此每天產生的監測數值皆有較大的變異性。
研究結合Civil 3D與Unity建立管理互動平台，使監測數據之趨勢能以視覺化的方式呈現於其中，提供判讀，另外亦建立狀態表單填寫功能並將狀態摘要呈現於模型對應位置，供管理人員便於追蹤及瀏覽狀態之用。
本研究提出一個以低成本設備應用於軌道監測之可行性方案，並結合遊戲引擎將數據應用於後端平台之架構。期後續能廣泛應用，以增加軌道監測之效率。

In recent years, many technologies such as IoT and game engine can be seen in engineering fields, but less in railway. Therefore, this study attempts to establish a railway condition monitoring system and a backend interactive platform. Proposing a preliminary framework of monitoring network. So as to expand the scope of track maintenance.
This study using Arduino which connecting weight sensor, accelerometer and strain gauge to monitor the dynamic lateral resistance, vibration and strain generated when the train passes through the ballast track. In terms of transmission, use low-power wireless module to transmit data and compare the characteristics and effects of XBee and Cat M1 .
Selecting one of train from each type of train(Tze-Chiang / Puyuma / Local train)to analysis their trend. It is found the dynamic lateral resistance showed a slight upward trend, the vibration showed upward trend in Tze-Chiang and Local train, but Puyuma in downward. Because Tze-Chiang is Push–Pull train, so the the values generated every day have great variability.
Finally, use Unity to build a manage interactive platform, present the data trends in the user interface. The monitoring information on-site can correspond to the model position. It is easy for manager to operate with data visualization. Also design a form that allows to fill in the status description for follow up management.
Due to using the low-cost IoT devices, it provides a low-cost solution for railway monitoring, which is suitable for extensive deployment and serves as an auxiliary state judgment.
