Ethernet Interface Dual Acceleration Acquisition System With 24-bit A/D Converter

This paper presented a dual acceleration acquisition system which was composed of 24-bit A/D converter,1-wire temperature sensor,single-chip microcomputer and Ethernet chip.It expounded the A/D conversion,temperature acquisition,the realization of the UDP protocol,calibration of the acquisition results,the establishment of acquisition software and many other important aspects of the method.On the basis of these,it structured the acceleration data acquisition system,preceded the real test and applied the scheme to road surface smoothness detection system.
