Under the ground that the next generation of power systems is constructing, our research work focuses on the core capabilities of power communication networks for transmission lines, including coverage, service-bearing capacity, flexibility and convenience, and technical security. We propose a convergence solution of heterogeneous networks to form a stable and reliable communication link based on 5G, ad hoc networks, and other technologies to solve the problem of poor network coverage in remote areas and realize data collection and remote control in areas without signal coverage. This system supports the establishment of intelligent monitoring and inspection of overhead transmission lines, offers an early warning service network system, and promotes the improvement of power digital space holographic perception and interconnection capabilities. Finally, we will realize an all-time communication named “anytime, anyplace, always online.”
The State Grid actively promotes the development of a new power system. The internet of things for power transmission and transformation equipment, for example, is a significant way to open up the "last mile" of power grid communication. In this paper, we design a sensor terminal serial communication module to meet the internet of things business requirements for power transmission and transformation equipment while also realizing sensor data collection and reporting functionality. The results of the tests show that the serial communication module designed in this paper can help the sensing terminal and reliably report sensing data to the upper-layer access node.
