碩士 === 明志科技大學 === 電子工程系碩士班 === 105 === With continuous improvement of semiconductor technology and the popularization of smart handheld devices, a lot of IoT (Internet-of-Things)-based embedded equipment has been used in our daily life, resulting in the development of smart home, smart city, and smart industry. In this study, we design a remote-monitoring system to improve the shortcomings of the traditional PLC (Programmable Logic Controller) industrial control system. A STM32F103 (Developed by STMicroelectronics) microcontroller unit is used as the master controlling chip, and a HLK-RM04-WiFi (High performance embedded UART-ETH-WiFi) is used as the communication module. The PLC devices are replaced by STM32 microcontroller units because they are more reliable and lower price. This system is operated remotely by personal computer or mobile phone. Smart handheld devices send specific commands to STM32 via internet to start forward/reverse rotation of two AC motors connected to STM32, meanwhile the data from STM32 are collected by sensors and the condition of the system operation are sent back to the handheld devices. Thus the remote monitoring system is implemented.
