Abstract: In the strong winds and large temperature difference areas of Xinjiang, the axial force of fastener is easy to drop due to the environmental impact, resulting in power transmission safety accidents and other issues. Based on the electric internet of things (EIoT) and embedded technology, this paper designs a remote temperature, wind speed and axial force monitoring system. The whole system consists of three parts: field data collection, network sensor module and cloud server. The high-precision sensor collects the field data, and the MCU processes and stores the data. The network sensor module composed of GSM chip and an Ethernet gateway transmits data to a cloud server in real time. Based on MySQL database, Apache and Java technology, the cloud server realizes data storage, analysis and real-time graphical display. The field test shows that the system can effectively monitor the tower with high failure rate area, improve the stability of the line, and ensure the safety of the line. In addition, it can provide first-hand data for improving the fastening construction technology and studying the relationship between the axial force drop and environmental factors.
