[Abstract]:In recent years, with the continuous development and maturity of bus technology and electronic information technology, the modular virtual digital oscilloscope is becoming more and more integrated and miniaturized. There is also a higher demand for flexibility and versatility in applications, led by NI, a world leader in virtual instruments. It has become an important trend in the development of virtual instrument software technology to realize the general use of soft panel and the interchangeability of instrument. This subject has completed the design of universal soft panel and instrument driver for oscilloscope virtual instrument. In other words, the design of general soft panel and instrument driver based on different bus type oscilloscope modules not only improves the standardization and flexibility of the software, but also improves the reusability and maintainability of the software. It is convenient for software designers to appropriately add or change the functions of instruments according to the needs of users, so as to meet the needs of increasing variety of customer applications. This paper analyzes the overall work flow of oscilloscope system, and puts forward the general scheme of general software design. Using the XML configuration file analysis and the IVI oscilloscope technical specification, has realized the soft panel universal and the instrument driver universal, the main research content is as follows: 1. Designs the knob control, builds the modular soft panel interface, including the channel setting module, Horizontal setting module, trigger setting module, waveform display module, parameter measurement display module and extended function module .2. analyze XML configuration file, realize dynamic update of soft panel .3. for oscilloscope module including waveform output function, Design a simple interface of arbitrary waveform generator .4.Design a general instrument driver framework according to IVI-C oscilloscope specification, which includes oscilloscope driver layer and oscilloscope special driver layer .5. complete the encapsulation of XML files of each oscilloscope module. For application software analysis to update soft panel .6. complete the encapsulation of each function in the special instrument driver of PXI oscilloscope module, and realize the control of the I / O interface of oscilloscope hardware module. The three oscilloscope modules based on USB bus are added to the instrument driver to realize the general purpose of the instrument driver. The debugging of the four boards of the PXI oscilloscope module and the PXI oscilloscope module is completed, and the generality of the software is verified.
