【摘要】：随着电子集成电路、微/纳机电技术的不断改善,使微能量的收集、应用成为可能。在一些领域,如微功耗电子产品、无线传感网络等,渐渐可以见到它的身影。可以预见,微能量的收集、应用将变得越来越普遍。振动微能量收集技术是目前研究、应用实践最多的一种。论文结合项目需求背景,开展了无源压电开关控制器的研究,作为微能量收集、管理、应用系统研究的重要部分,野外或不便布线控制用电设备的场合,实现无源开关控制。首先,就振动能量收集应用作了大量的调研,了解认识了国内外的研究、应用现状。通过查阅文献、实验仿真等,验证了振动能量收集并为微功耗电子元器件供能是可行的。自供电的无源遥控开关在保留有源遥控开关控制器优点的同时,又解决了有源遥控开关需要更换电池的局限性。其次,给出了无源压电开关控制器的整体实现方案。详细讨论了能量转换与处理单元,详细的分析、阐述了无线发射单元、无线接收单元。给出了具体的设计流程与电路并设计制作了电路模块。最后,对压电开关控制器的各功能单元及开关控制器整体进行了实验仿真。实验仿真表明,能量转换单元可以将按压开关控制器按钮的机械能转化为电能,并将此能量用于发射实现控制功能的编码信号。实际测试表明,压电片转换电压可达20V左右。借助具体专用的微能量收集管理芯片对所转换的振动能量进行处理,可以得到较稳定的直流电压(可选择设置为:3.45V、4.1V、4.5V、5V)。此外,对压电开关控制器的发射与接收单元进行了实验,并与稳压源供电情况下进行了比较。实验表明,通过收集压电发电装置将动作开关控制器按钮的机械能转化来的微弱电能,可以实现控制信号的发射,但是遥控距离要小于直流稳压源供电的情况下。
[Abstract]:With the continuous improvement of electronic integrated circuit and micro / nano electromechanical technology, it is possible to collect and apply micro energy. In some fields, such as micro power electronic products, wireless sensor network and so on. It can be seen gradually. It can be predicted that the application of micro-energy collection will become more and more common. Vibration micro-energy collection technology is one of the most studied and applied practice at present. Research on passive piezoelectric switch controller, as an important part of micro energy collection, management, application system research, field or inconvenient wiring to control the situation of electrical equipment, to achieve passive switch control. First of all. A great deal of research on vibration energy collection has been done, and the research and application status at home and abroad have been understood. Through consulting literature, experimental simulation and so on. It is proved that it is feasible to collect vibration energy and provide energy for low-power electronic components. The self-powered passive remote control switch retains the advantages of active remote control switch controller at the same time. It also solves the limitation that the active remote control switch needs to replace the battery. Secondly, the overall realization scheme of the passive piezoelectric switch controller is given. The energy conversion and processing unit are discussed in detail, and the detailed analysis is given. The wireless transmitting unit and the wireless receiving unit are described. The specific design flow and circuit are given and the circuit module is designed and manufactured. Finally. The experimental results show that the energy conversion unit can convert the mechanical energy from pressing the button of the switch controller to electric energy. And this energy is used to transmit the coded signal to realize the control function. The conversion voltage of piezoelectric chip can reach about 20V. The vibrational energy can be processed by specific micro-energy collection and management chip. A more stable DC voltage can be obtained (optional: 3.45V / 4.1V / 4.5V / V). In addition, the transmitting and receiving units of the piezoelectric switch controller are tested. The experimental results show that the control signal can be transmitted by collecting the weak electrical energy from the mechanical energy of the switch controller button. But the remote control distance is smaller than the DC power supply.
