The Software Design Of Acquisition Card For Nuclear Pulse Shape Based On DSP

Surveying the digitization of the signal wave form gathering with processing method in nuclear radiation is one of the most important subjects in the nuclear information obtained and dealt with search field at present. In order to support the new type system of nuclear signal wave form gathered basic on high speed ADC and DSP with software system, this text has been discussed on the design of the systems software specially.The paper has summarily introduced the basic principle with nuclear signal gathering and the analyticle system, has analysed the basic demand dealing with the signal in the nuclear physical experiment, has put forward the design plan of the specific new-type nuclear signal gathering system and has also put forward the main thought of system software design according to the requests of the general nuclear measuring experiments.The system has set up the structure frame of software with the line of the procedure of data, proceed from the point view of the kind of structure, has concretly designed the algorithm of every part in the software. It adopt the level model, divide the whole system into several layers and partly design, convenient for the expansion of the function and modification of the software. It has summarized the principle and general step of designing drive program of Windows, has explained the concretly realizing of application program and hardware communication through the design of the meeting programm. Designed as the systematic prototype, The paper explain thedesign of application function especially on wave form show and the realization of multilane analyzing function.The whole software system debug succeeding at Visual C++ 6.0 platform. Cooperate with the hardware system, it can used as the universal digital oscillograph , also used as specific processing and analyzing system of nuclear signal measureing data . have real project using value.
