Multi-Channel Simultaneous Data Acquisition System with Variable Sampling Rate

Abstract:

Data Acquisition System is very important for Environmental Detection Robot in its self-positioning or measuring the spatial distribution of the concentration of poisonous and harmful gases, so the sampling frequency adjustable multi-channel synchronous data acquisition system was designed to satisfy the requirement of Environmental Detection Robot. Signal conditioning circuit,AD7606 interface circuit and the sampling frequency adjustable function were introduced in detail. The performance test results indicate that the data acquisition system can acquire multi-channel Data Simultaneously in real time, furthermore, the sampling rate and input voltage range can be set according to need, its provides the guarantee For environmental detection robot's follow-up data analysis.
