针对连续阴雨天太阳能电池效率下降时,基于CC2430的无线传感器供电电源不能及时传输故障信息的问题,提出了一种利用半导体温差发电技术结合单晶硅太阳能电池为无线传感器持续提供电能的新方法,实现了在无现场供电的情况下,变电站运行设备中大电流回路连接点发热温度的实时采集。对比分析了在不同光线强度下,单晶硅太阳能电池对超级电容充电性能的影响,并设计了测温节点的软件程序。
Aiming at the problem that when the solar cell efficiency of continuous rainy days falls, the power supply of wireless sensor based on CC2430 can not transmit the fault information in time. A new method of using semiconductor thermoelectric power generation technology combined with monocrystalline silicon solar cell to continuously supply power for wireless sensor is proposed. In the case of no on-site power supply, real-time acquisition of the heating temperature of the connection point of the large current loop in the substation running equipment is realized. The influence of single crystalline silicon solar cells on the charging performance of supercapacitors under different light intensities was analyzed and compared, and the software program of temperature measurement node was designed.
