【摘要】：隨著電子集成電路、微/納機(jī)電技術(shù)的不斷改善,使微能量的收集、應(yīng)用成為可能。在一些領(lǐng)域,如微功耗電子產(chǎn)品、無線傳感網(wǎng)絡(luò)等,漸漸可以見到它的身影�？梢灶A(yù)見,微能量的收集、應(yīng)用將變得越來越普遍。振動微能量收集技術(shù)是目前研究、應(yīng)用實踐最多的一種。論文結(jié)合項目需求背景,開展了無源壓電開關(guān)控制器的研究,作為微能量收集、管理、應(yīng)用系統(tǒng)研究的重要部分,野外或不便布線控制用電設(shè)備的場合,實現(xiàn)無源開關(guān)控制。首先,就振動能量收集應(yīng)用作了大量的調(diào)研,了解認(rèn)識了國內(nèi)外的研究、應(yīng)用現(xiàn)狀。通過查閱文獻(xiàn)、實驗仿真等,驗證了振動能量收集并為微功耗電子元器件供能是可行的。自供電的無源遙控開關(guān)在保留有源遙控開關(guān)控制器優(yōu)點的同時,又解決了有源遙控開關(guān)需要更換電池的局限性。其次,給出了無源壓電開關(guān)控制器的整體實現(xiàn)方案。詳細(xì)討論了能量轉(zhuǎn)換與處理單元,詳細(xì)的分析、闡述了無線發(fā)射單元、無線接收單元。給出了具體的設(shè)計流程與電路并設(shè)計制作了電路模塊。最后,對壓電開關(guān)控制器的各功能單元及開關(guān)控制器整體進(jìn)行了實驗仿真。實驗仿真表明,能量轉(zhuǎn)換單元可以將按壓開關(guān)控制器按鈕的機(jī)械能轉(zhuǎn)化為電能,并將此能量用于發(fā)射實現(xiàn)控制功能的編碼信號。實際測試表明,壓電片轉(zhuǎn)換電壓可達(dá)20V左右。借助具體專用的微能量收集管理芯片對所轉(zhuǎn)換的振動能量進(jìn)行處理,可以得到較穩(wěn)定的直流電壓(可選擇設(shè)置為:3.45V、4.1V、4.5V、5V)。此外,對壓電開關(guān)控制器的發(fā)射與接收單元進(jìn)行了實驗,并與穩(wěn)壓源供電情況下進(jìn)行了比較。實驗表明,通過收集壓電發(fā)電裝置將動作開關(guān)控制器按鈕的機(jī)械能轉(zhuǎn)化來的微弱電能,可以實現(xiàn)控制信號的發(fā)射,但是遙控距離要小于直流穩(wěn)壓源供電的情況下。
[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.
