Aiming at problem of poor real-time

low reliability

low error detection ability of geotechnical engineering data acquisition system based on RS—485 bus

intelligent sensor node based on CAN bus is designed and communicate with geotechnical engineering monitoring system. Mainly introduce design of hardware and software of intelligent sensor node. By means of application of displacement meter based on CAN node in engineering safety monitoring

results show that the intelligent sensor node has characteristics of stable working

reliable property

and high precision.
