Abstract
For the demand of the storage tank bottom acoustic emission testing methods
an acoustic emission signal collecting system is designed based on PC104 framework.The receptor of the system is acoustic emission sensor and PC104 data collecting module and CPU module are used as control core
which is used to collect and save the signal.Approved by experiment
the system can collect and save the emission signal exactly by less than 1 % error
which meets the demand of the system design and creates essential condition for the acoustic emission testing means.
