隨著資訊產業與通訊技術越來越精進，許多產業紛紛開始進行轉型及新技術的導入。其中，物聯網(Internet of Things, 簡稱IoT)將各式裝置與聯網構想做整合，逐步達成過去難以實現的智慧化應用，並使得智慧製造的影響將廣泛遍及整個產業鏈。另一方面，無線通訊技術的蓬勃發展也使得人們對於行動裝置的使用程度日益增高，越來越多產品可與手機及平板電腦等裝置進行連線，提供給消費者更加便利與即時的使用體驗。

而無線通訊技術中，無線熱點(Wi-Fi)與低功耗藍牙(Bluetooth Low En-ergy, 簡稱BLE)在自動化產業中應用最為廣泛。如要實現一個無線監測系統，雖然目前已經可以達成，但存在有耗電量高與受區域限制的問題。為了改善此問題，專家們提出了窄帶物聯網(Narrow Band -Internet of Things, 簡稱NB-IoT)技術，它能進行遠距離的資料傳輸且耗電量極低，非常適合應用在資料傳輸率不會太高且傳輸範圍廣的場合。本工業物聯網平台將傳統的監測系統進行改良，除導入NB-IoT的技術外，更搭配了有助於降低流量的消息隊列遙測傳輸(Message Queueing Telemetry Transport, 簡稱MQTT)協定。其中，工業物聯網平台主要實作三個部分，分別是網頁伺服器、資料庫伺服器以及MQTT伺服器，其餘再透過手機應用程式以及實驗室自行設計的感測節點與工業物聯網平台進行資料交換。

本研究選擇工具機加工產線作為實驗環境，經過各項實驗與測試，驗證了工業物聯網平台的可行性與穩定性。除了距離方面不再受限外，在網路傳輸流量上也有明顯的改善。最後，在測試結果中，分別掛機6小時、12小時與24小時的資料完整率皆達到90%以上。此外，本研究也與中部工具機廠商以及物聯網廠商進行實機的測試，希望透過實際測試來持續改善此研究方向。

With the development of information industry and communication technology more and more advanced, many industries have begun to carry out transformation and the introduction of new technologies. Among them, the internet of things will be a variety of devices and networking ideas to integrate, and gradually achieve the past difficult to achieve intelligent applications, and make the impact of intelligent manufacturing will be widespread throughout the industry chain. On the other hand, the rapid development of wireless communication technology also makes people's use of mobile devices increasingly, more and more products can be connected with mobile phones and tablet computers and other devices online, to provide consumers with more convenient and real-time use of the experience.

Wireless hotspots and bluetooth low energy are the most widely used in the automation industry. If a wireless monitoring system is to be achieved, although it can now be achieved, there are problems with high power consumption and area restrictions. To improve this problem, experts have proposed narrow-band internet of things technology, which can transmit data over long distances and consume very little power, making it ideal for applications where data transfer rates are not too high and transmission ranges are wide. This industrial internet of things platform improves the traditional monitoring system, in addition to the technology of importing NB-IoT, with message queue telemetry transport protocol that helps reduce traffic. Among them, the industrial internet of things platform is mainly made into three parts, namely, web server, database server and MQTT server, the rest through mobile phone applications and laboratory-designed sensing nodes and industrial internet of things platform data exchange.

In this study, the tool machine production line as the experimental environment, after various experiments and tests, verified the feasibility and stability of the industrial internet of things platform. In addition to the no longer limited distance, there is also a significant improvement in network traffic. Finally, in the test results, the data integrity rate of 6 hours, 12 hours and 24 hours, respectively, reached more than 90%. In addition, this study also with the central tool machine manufacturers and internet of things manufacturers to carry out real-world testing, hoping to continue to improve the direction of this research through practical testing.
