基于压电俘能器的免电池学习型遥控开关

传统的电气开关（尤其是照明开关）的安装布线耗时费力，而且成本高；控制方式也过于单一；使用遥控器又需要经常更换电池。为克服这些缺点，研制了一种基于压电俘能器的免电池学习型的射频遥控开关。其特点是利用压电俘能器为整个发射器供电，通过无线射频技术与接收器通信，由接收器给用电设备发出控制信号，并可以储存发射器与接收器的对应关系。整套系统可以很方便地实现无线智能遥控，而且环保免电池维护，可靠性高，具有很高的实用价值。

A Battery-Free Learning Remote Control Switch Based on the Piezoelectric Energy Harvesters

The installation and wiring of traditional electrical switches, especially the lighting switches, are time- consuming, laborious and high costs. Also the control is too single and it often needs to replace batteries for the remote con trol. To overcome these shortcomings, based on the piezoelectric energy harvesters, a battery-free learning radio frequency remote control switch is designed. The characteristics of this control switch are that it uses piezoelectric energy harvesters for the power supply of the whole transmitter; through the radio frequency technology, it communicates with the receiver, which then gives control signals to the electricity equipment; it can also store the relationship between the transmitter and receiver. The entire system can easily achieve intelligent wireless remote control. It is environmental protection without batteries maintenance and of high reliability and high practical value.
