Abstract

Abstract : In this paper, we focus on building and researching the self-power sensor system based on the tiny energy harvesting technology which can be used in the scenario of ubiquitous power Internet of Things (UPIoT) and prove the possibility and efficiency for the life extension of transmission line intelligent sensing system. Large scale of sensor in the smart grid technology application, especially in high-voltage transmission lines, is not convenient; it is worth mentioning that most of all kinds of sensor node equipment using battery power make the life of the equipment or components limited by greatly. Therefore, low power consumption, long life, no battery dependence, free maintenance, and other requirements are increasingly important to solve the difficulties of deployment and maintenance. At the same time, the problem of the battery case electricity use with low efficiency and short life of sensor node has become the bottleneck of further widely deployed wireless sensor node equipment. The power collection technology based on environmental energy can effectively handle with the problems of energy collection efficiency and management that need to be urgently solved in new application scenarios such as zero-standby power consumption devices, remote active tags, battery-free telemetry and remote control, and ultralong life sensing system. By studying various kinds of environmental energy collection technologies and utilizing the conversion and management technologies of available weak environmental energy, such as solar energy and magnetic field energy, into electric energy, this paper establishes an energy conversion test system and configuration model and verifies the feasibility of the assumption of maintenance-free for the intelligent sensing system of transmission lines.
