后备机种市电侦测方法
<1> 市电频率范围:
50Hz:46Hz~54Hz
60Hz:55Hz~65Hz
<4>市电波形衰减率:84/1
<5>市电AD转换公式:
(1)市电AD转换值 = ((Vip / 84) / 5V) * 256 + Voffset
(2)如:以市电电压100V为例,其所对应的AD转换值:
AD转换值 = ((100 / 84)/ 5V) * 256 = 61T;
-City reserve aircraft detection methods < 1> City frequency range: 50Hz: 46Hz ~ 54Hz 60Hz: 55Hz ~ 65Hz < 4> City waveform attenuation rate: 84/1 < 5> City AD conversion formula: (1) City AD conversion value = ((Vip/84)/5V)* 256+ Voffset (2) such as: voltage 100V power to the city as an example, it corresponds to the AD conversion value: AD conversion value = ((100/84)/5V)* 256 = 61T
