Research on Monitoring Platform of Smart SPD Based on Cloud System

Smart appliances refer to a class of devices that have monitoring, protection, control, and communication functions, such as smart circuit breakers, smart contactors, smart surge protective devices (SPD), and so on. However, the manual maintenance of these smart appliances has security risks because of missed and false detections. In order to reduce the difficulties in SPD maintenance, the smart SPD is taken as the research object in this paper. The IoT cloud platform technology is used to develop the smart SPD online monitoring system. The system is divided into the device-side and the application-side. When designing the device-side, a Python program is written to collect the data from the SPD and send the data to the cloud platform. When designing the application-side, the Aliyun IoT platform is used to manage the SPDs and develop the Web application. After the design, all parts of the monitoring system are tested. The results show that each part of the system operates well and can achieve the desired goal.
