Abstract
The utility model discloses a multichannel analog data collection system relates to the communication technology field, include: sensor, multichannel analog switch, signal amplifier, wave filter, sampling holder, AD converter, singlechip, transceiver. Multichannel analog switch is used for multichannel signalling channel to switch, and a certain moment is in the on -state only all the way. The amplifier can enlarge analog signal, has improved the precision that analog signal is digital and data signal handles at the back. The wave filter belongs to low pass filter, mainly simulates filtering to the noise that the amplifier produced, has improved the precision, has reduced the pollution of noise. Analog signal is trailed to the utensils of sampling / keep, when starting the AD transform, keeps incoming signal, has avoided AD to change the error of bringing.
