| Abstract: | The solution to forming a data acquisition system for the isothermal pipe laying experiment was introduced,which was based on VB and PC-6319.The technology of DLL,which can obtain the measurement by reading and writing the I/O ports,was particularized.The general formulation of transform about each channel of PC-6319 was also presented.The problem with zero excursion in the transducer was analyzed and solved,and the debug method of the system software programmed by VB was applied. |
