隨著工業4.0產業與應用逐漸升高，除了因應工業需求所開發新的工業乙太網路技術之外，亦帶動物聯網-無線感測網路的應用也隨之大幅地發展，進而誕生出將物聯網與工業乙太網路結合的新概念──工業物聯網(IIoT)。
在工業物聯網的應用中，許多設備在聯網的同時要求極佳的計算能力與最低的功耗。在工業乙太網路技術中，由於EtherCAT具備高速的通訊效能、即時的通訊系統及低成本的主站硬體架設。因此。本研究透過自行設計的EtherCAT從站模組，能有效實現EtherCAT工業乙太網路之功能，並以 EtherCAT網路將所有從站以環狀網路連接。本研究使用Wireshak封包解析軟體對本系統之EtherCAT網路進行解析，在四組從站連接的情況下，每個封包傳輸延遲時間為0.2ms。同時，以具備EtherCAT協議之馬達驅動控制器ECAT-2091S對步進馬達17HS1910以Position control運動模式進行馬達週期運轉測試，以驗證EtherCAT之點對點控制，並繪製出馬達加速曲線圖與位移曲線圖以進行解析。
此外，EtherCAT從站模組中，連結無線傳輸模組USR-WIFI232連接低功耗無線感測模組，實現無線感測網路之功能。其中，本研究所自行設計的低功耗無線感測模組對逕向動力刀座進行實際機台測試，並透過EtherCAT主站感測與擷取機台溫度與震動訊號。其中，震動訊號以傅立葉轉換可得到時域頻譜，並可作為後續機台狀況之判斷依據。
而低功耗無線感測模組在M4 LPDS+NWP connect AP模式下，電流消耗大約為6.82mA，若以2000mA/H電池持續供電，低功耗無線傳輸模組可連續傳輸12天。最後，本研究將自行設計的EtherCAT從站模組與低工耗無線感測模組進行整合，實現出能即時偵測機台並長時間觀察機台狀況之具備EtherCAT之低功耗智慧機械感測系統。

With the gradual increase of Industry 4.0 industry and application, in addition to the development of new industrial Ethernet technology in response to industrial demand, the application of the animal network-wireless sensing network has also been greatly developed, resulting in the birth of The new concept of combining the Internet of Things with industrial Ethernet - Industrial Internet of Things (IIoT).
In industrial IoT applications, many devices require excellent computing power and lowest power consumption while networking. In industrial Ethernet technology, EtherCAT has high-speed communication performance, instant communication system and low-cost master station hardware erection. therefore. In this study, the EtherCAT industrial Ethernet module can be effectively implemented through the self-designed EtherCAT slave module, and all the slave stations are connected in a ring network via the EtherCAT network. In this study, the Wireshak packet parsing software is used to parse the EtherCAT network of the system. In the case of four groups of slaves connected, the transmission delay time of each packet is 0.2 ms. At the same time, the motor drive controller ECAT-2091S with EtherCAT protocol is used to test the motor cycle of the stepper motor 17HS1910 in the Position control mode to verify the EtherCAT point-to-point control, and draw the motor acceleration curve and displacement curve for the motor. Analysis.
In addition, in the EtherCAT slave module, the wireless transmission module USR-WIFI232 is connected to the low-power wireless sensing module to realize the function of the wireless sensing network. Among them, the low-power wireless sensing module designed by the Institute performs the actual machine test on the radial power tool holder, and senses and extracts the temperature and vibration signals of the machine through the EtherCAT master station. Among them, the vibration signal can obtain the time domain spectrum by Fourier transform, and can be used as the basis for judging the condition of the subsequent machine.
The low-power wireless sensing module consumes about 6.82 mA in the M4 LPDS+NWP connect AP mode. If the battery is continuously powered by the 2000 mA/H battery, the low-power wireless transmission module can transmit continuously for 12 days. Finally, this study integrates the self-designed EtherCAT slave module with the low-power wireless sensing module. EtherCAT's low-power smart mechanical sensing that enables instant detection of the machine and long-term observation of the machine's condition.
