영문 초록

In this study, a smart sensor was manufactured to operate on the Internet using an Arduino module. This sensor was programmed to connect to the MQTT broker by connecting to the Internet via Wi-Fi. The OPC server, which is a heterogeneous communication system, was set up to connect to the MQTT broker by connecting to the Internet through a wire. The MQTT broker served to relay data from the smart sensors to the OPC servers and smartphones. The sensor data reaching the OPC server were transmitted to the signal display device. The process by which the data reach the signal display device via the MQTT broker and OPC server is known. However, the transmission characteristics of the data have not been clarified yet. Two experiments were conducted to evaluate the performance of the communication systems connected through the smart sensor, MQTT broker, OPC server, and signal display device. The first experiment was conducted to measure the time taken by the program code of the Arduino module. In the second experiment, five sinusoidal signals were input to the smart sensor, and they were monitored and stored in the signal display device. The experimental results clarified the transmission time and transmission frequency of the smart sensor based on the OPC server.
