Monitoring System Design of Suspension Bridge of Health Status Based on CAN-BUS
The article introduces a data acquisition system of multi-channel suspension bridge vibration acceleration with the core of STC12C5606AD single chip. The system used CAN Bus to accomplish the communication between the front extension and IPC. The IPC could quickly get up to 42 channels acceleration value of mean-square deviation in a second and the real time oscillogram from the partial channels after the front machine had the statistical process. The article also analyses problems in the process of system design such as A/D data acquisition rate, transport protocol, and establishing database more than 10 G bytes storage.
