Abstract

The growth of crops is affected by factors such as temperature, humidity, and salinity, so it is critical to monitor these indicators through detectors in smart agriculture. Collecting renewable energy in the farmland environment to power the detector will provide a feasible approach. Therefore, a triboelectric-photovoltaic hybrid generator (WS-TPHG) is proposed to collect solar and wind energy efficiently. The generator structure includes a photovoltaic panel (PV) and a wind-driven triboelectric nanogenerator (W-TENG). The switching function of the power supply can be realized through the power management circuit. In the case of sufficient light, the detector is powered by PV steadily, and in the case of insufficient light, the detector is powered by W-TENG via the switching function. The PV can supply a stable voltage of 8.1 V, and the open-circuit voltage (V_OC) of W-TENG can reach 478.6 V at 180 rpm. The results verify that the detection of temperature, humidity, and salinity can be successfully achieved through the detector which is powered by WS-TPHG. In this article, the potential application of WS-TPHG is demonstrated in farmland to provide a solution for the sustainable development of agriculture.

使用三电-光伏发电机的风能-太阳能混合自供电探测器系统，用于智能农业

农作物的生长受到温度、湿度和盐度等因素的影响，因此在智能农业中，通过探测器监测这些指标至关重要。在农田环境中收集可再生能源为探测器供电将提供一种可行的方法。为此，提出了一种摩擦电-光伏混合发电系统（WS-TPHG）来高效地收集太阳能和风能。发电机结构包括一个光伏板（PV）和一个风力驱动的摩擦纳米发电机（W-TENG）。电源的开关功能可以通过电源管理电路来实现。在光照充足时，探测器稳定使用PV供电，光照不足时，探测器通过开关功能使用W-TENG供电。PV可提供8.1 V的稳定电压，W-TENG的开路电压（VOC）在180 rpm时可达478.6 V。实验结果表明，采用WS-TPHG驱动的探测器可以成功地实现温度、湿度和盐度的检测。本文论证了WS-TPHG在农田中的潜在应用，为农业可持续发展提供解决方案。
