Abstract

Abstract:

With the construction of the national smart grid, there are more and more sensors in substations, and due to the large area of substations, how to unify the management, monitoring, and maintenance of substation devices has become an urgent need. Wireless mesh network has the ability of self-organization of network and self-healing, and can independently control each node to meet the above requirements. In this paper, ESP32 was used as the hardware node module, and its own WIFI module was used to configure and network the Mesh network. The connection and communication between the sensors and ESP32, the data transfer from lower computer, and the data analysis and database saving operations from upper computer were realized. In addition, a complete Mesh network framework was established. The test results show that the system has a simple and clear structure, quick deployment, easy maintenance, which basically meets the implementation of the Internet of things (IoT) in a substation environment.

Key words: Mesh network, substation, power Internet of things (IoT), ESP32
