The disadvantage of wireless communication is that signals are easily affected via severe industrial environment and degrades the accuracy of receiving data. For wire communications, the supplying power cores of processing machines usually cause significant noise and reduce the signal to noise ratio resulting in low accuracy of data communications. In addition, multiple wires of various sensors mounted on machines increase the complexity of wire management. Therefore, we proposed an indoor solar cell based 5G communication system which can be integrated with other subjects for intelligent manufacturing. The proposed system is composed of an indoor solar cell module, a 28 GHz wireless communication module from Chunghwa Telecom, and a software define radio. It can transfer the measured vibrational signals and other measured information of subject 1, subject 3, and subject 5 to final terminal or cloud for data analysis and real-time monitoring. The advantages of the propose system include: 1. the size of antenna and entire system is small which can be mounted of manufacturing machines and avoid complicated wire network of multiple sensors, 2. high-efficient perovskite solar cell can gain indoor energy and supply sufficient power to sensors for long-tern usage and real-time monitoring. It can also prevent the power-cable-induced ground noises. 3. The proposed system can achieve direction finding and reduce the signal inference in industrial environment via multi-port impedance matching techniques and MUSIC algorithms.高效率太陽能電池;5G無線通訊模組;方向判定;MUSIC演算法;high-efficient solar cell; 5G wireless communication module; direction finding; MUSIC algorithm高等教育深耕計畫-核心研究群計畫【室內太陽能電池結合5G無線傳輸系統應用於智慧製造】
