中文摘要:
      针对履带起重机稳钩控制系统中无线传感节点的自供能需求,提出一种基于低延迟改进型自供能并联电感同步开关(ISP-SSHI)的高效能量收集电路。对自供能并联同步开关电感收集电路的开关响应开展了理论模型研究,分析了整流电路开关延迟(SD)对能量收集效率的影响规律,并改进设计了基于ISP-SSHI电路的无线传感节点,研制了实验节点装置并进行了工程对比实验。结果表明,改进后电路与自供能并联电感同步开关(SP-SSHI)电路相比输出功率提高了15.5%,与标准能量收集电路(SEH)相比输出功率提高了121.8%,满足工程机械装备的需求。
英文摘要:
      Aiming at the self-powered demand of wireless sensor nodes in the crawler crane hook stabilization control system, a high-efficiency energy harvesting circuit based on a low-latency improved self-powered parallel synchronized switch harvesting on inductor (ISP-SSHI) is proposed. A theoretical model study is carried out on the switching response of the self-powered parallel synchronous switch inductance collection circuit, the influence of the switching delay (SD) of the rectifier circuit on the energy collection efficiency is analyzed, and a wireless sensor node based on the ISP-SSHI circuit is designed. The experimental node device is developed and the engineering comparison experiment is carried out. The results show that the output power of the improved circuit is increased by 15.5% compared with the self-powered parallel synchronized switch harvesting on inductor(SP-SSHI)circuit and an increase of 121.8% compared with the standard energy harvesting(SEH)circuit, which could meet the needs of construction machinery equipment.
