Based on CAN/USB bus measuring radon multi-channel data acquisition system

The monitoring and controlling aspect of dynamic evolution process of mining-induced fractures in the study about soil radon α energy spectrum anomaly regularity of the process of rock collapse, need a reliable and effective, easy to operate method and means. To work out the issue this article puts forward a measuring radon multi-channel acquisition system based on the USB bus and CAN bus, which transmits data through the CAN bus and achieves a multi-node communication and improves communication quality; in the meantime, using USB interface achieve the link of CAN bus network and the computer and data collection solutions.
