超低功耗无线触摸按键开关设计
|
摘要
针对当前有线开关需要提前在墙壁内铺设电力线及无线开关存在的有线供电以及使用不便的弊端,设计了一种超低功耗无线触摸按键开关。通过CR2032纽扣电池实现供电,通过超低功耗触摸按键芯片TTP223实现按键检测,通过无线编码芯片PT2262和无线解码芯片PT2272实现点对点无线通信,通过优化无线发射电路降低了开关待机功耗。经过试验研究,该触摸按键开关无线发射端无按键动作时,只有低功耗触摸按键芯片TTP223耗电,耗电电流为12.7μA;按键动作时整个无线发射系统耗电电流为257.5μA。一块CR2032纽扣电池的容量为240 mA。经过计算,无线开关的待机时间为2.16年,无线开关一直持续工作的时间为38.83天。试验结果表明,该无线开关正常使用的情况下完全满足1年以上的使用需求且无需更换电池。
In view of the drawbacks of wired switches need lay power lines in the walls in advance; and wireless switches need wired power supply and inconvenient in use,an ultra-low power wireless touch button switch is designed.Its power supply is conducted by CR2032 button battery,touching detection is realized by ultra-low power touching chip TTP223,point-to-point wireless communication is realized by wireless encoding chip PT2262 and wireless decoding chip PT2272; and standby power consumption of switches is reduced by optimizing wireless transmitting circuit.The experimental research show that only the low power touching chip TTP223 consumes power when there is no key action at the wireless transmitter of the touch button switch,and the power consumption current is 12.7 μA.The power consumption current of the whole wireless transmitter system is 257.5 μA when the key action is taken.The capacity of a CR2032 button battery is 240 mA; by calculation,the standby time of the wireless switch is 2.16 years,and the continuous working time of the wireless switch is 38.83 days.The experimental results show that this wireless switch fully meets the needs of more than one year in normal use and does not need to replace batteries.
