Abstract

Today's power systems are developing from traditional multi-sensor systems to ubiquitous power Internet of Things systems. By integrating the Internet of Things technology with the power system, the improvement of the power system will be a qualitative leap, making it more secure, stable, reliable and intelligent. The environmental backscatter technology makes the communication equipment get rid of the dependence on the power source, is more energy-efficient and efficient, and effectively extends the communication distance, which is very suitable for the power Internet of Things scene. However, device identification in the traditional power Internet of Things has problems such as low reliability and insufficient reading distance. Based on this, this paper designs a new type of tag antenna. This structure adopts omni-directional reception and directional transmission methods to achieve the purpose of comprehensive signal coverage for power Internet of Things application scenarios. It has the advantages of clean, low-carbon, efficient and practical.
