Description

technical field [0001] The invention relates to the field of sensors, in particular to an ultra-high frequency energy harvesting and communication sensing device. Background technique [0002] Generally speaking, traditional distributed sensor monitoring system solutions often solve large-scale and highly concentrated sensor monitoring problems, which require a greater degree of commonality or reproducibility in application scenarios. However, in the field of energy transmission and distribution such as power grids, such as GIS busbar pipe deformation monitoring, water level flooding monitoring, and substation equipment contact temperature rise monitoring, it often operates in an outdoor environment, or the collection points are scattered, or there are various types of equipment , Sensor monitoring will encounter problems such as inability to wire and build a sensor network. When solving the sensing and monitoring problems of such devices, the distributed and large-scale se...

[0004] At the same time, according to the existing passive technology solutions, although the on-chip passive wireless single-chip sensing solution has the advantage of small size, the sensor resources are single, and the application occasions are easily limited. With the expansion of the smart grid scale, power Power grid equipment presents a diversified development trend, and the single-chip sensing solution is not as good as the modular sensing solution in terms of adaptability

[0005] To sum up, all existing active sensing acquisition devices will be equipped with batteries. Ensuring the safety, stability and insulation operation of power equipment is the core concern of the power industry. The active solution with its own battery will undoubtedly introduce new sources of danger. ; and the existing passive sensing acquisition device, although the on-chip passive wireless single-chip sensing solution has the advantage of small size, but the sensor resources are single, and the application occasions are easily limited. With the expansion of the smart grid scale, the power grid Equipment presents a trend of diversification, and single-chip sensing solutions are inferior to modular sensing solutions in terms of adaptability
