為提升經濟成長率，各國無不致力於進行工業技術革新與轉型，使得現今智慧工廠的概念被廣泛討論。欲使工廠內各設備由自動化提升為智動化，需整合硬體與智慧化軟體技術，藉由取得設備各項資訊，如感測、動作控制、作動流程等，偕同生產線的各項資訊，並加以分析與運算。為此工廠將導入工業物聯網(IIoT)架構，下至感測器、致動器，上至機台控制器、雲端運算伺服器等，各設備間皆需要進行資訊傳輸並應用至大數據分析，使得統一的資訊格式與通訊協定更顯重要。
為此本研究開發一廠區製造資訊雙向互動系統，系統著重於通訊架構的設計，藉由於廠區內設備導入物聯網開放式通訊協定－MQTT，搭配以嵌入式系統開發之IIoT閘道器，並裝設於廠區機台周邊進行感測資訊之收集與過濾，以及機台控制資訊彙整之功能，達到機台與物聯網設備、機台與機台之間的聯網通訊，並以Android系統開發一行動化應用平台，使廠區內的人員能更加便利與快速得獲取所需的機台相關資訊，該平台採用MQTT的發佈(Publish)/訂閱(Subscribe)模式，進行應用功能設計，可達到資訊派送服務。
本系統可應用於資訊派送、輕型控制、警報通知等層面，實現機器與機器、人與機器之間的雙向資訊交流。

Countries are committed to innovation and transformation of industrial technology for improving the economic growth rate, hence smart factory is widely discussed. For upgrading equipments in a factory from automation to intelligent automation, it is necessary to integrate hardware and intelligent software technology by obtaining various information of the equipment, such as sensing, motion, and actuation, and then analyzing and computing them with the information of production line.
The architecture of Industrial Internet of Things (IIoT) will be imported into the device including sensor, actuator, machine controller, cloud computing server in a factory. Each device needs to exchange information with other device and apply to big data analysis. Therefore, the unified information format and communication protocol are more important.
A bi-direction manufacturing Information interactive system for factory developed in this thesis lays emphasis on the design of communication architecture. It achieves the communication of machine to IoT device and machine to machine by importing the open protocol－MQTT into the factory and equipping IIoT gateway developed through the embedded system with the machine to collect and filter sensing data and control information. An Android platform offer personnel in the factory to get the necessary information of the machine conveniently and quickly. The mode of publish/subscribe from MQTT is adopted in this platform to realize information delivery service.
The system can apply to information delivery, lightweight control, alarm notification, and so on. It can achieve bi-direction information exchange between machine to machine and human to machine.
