The Design And Implementation Of Measurement And Display Function Of Scopecorder

Scopecorder has both the display function of traditional oscillograph and the recording function of recorder.Compared with the design of the fixed channel and fixed window of the traditional oscilloscope,the oscilloscope recorder under this subject can realize the diversity of the number of channels,and design and realize the display of multi window according to the change of the number of different channels.The overall design of the Scopecorder under this subject uses the architecture of acquisition board card and signal processing main board and industrial control machine,and realizes the functions of measurement,display,recording and analysis of the waveform,and tests and verifies the related results.The main contents include:1.The measuring function of the Scopecorder.The module has 29 main parameters,which basically include user’s measurement parameters.The measuring module develops various measuring modes according to actual needs,including real-time measurement,real-time statistical measurement and historical statistical measurement.The measurement module of the measurement module has developed a variety of cursor measurement modes,which further expand the traditional measurement of the cursor in the Scopecorder record,and realize the multi-directional measurement of time,amplitude and angle.2.support variable channel,variable window waveform display,multiple view windows and mixed text display of measurement and display text.Especially when the most 128 channels are all opened,the design and implementation of interface display and interface layout are achieved.3.The display function of the Scopecorder.This part,starting from the basic display function,develops the waveform display for various collection modes,and develops the VECTOR view and BAR diagram for the power mode of the Scopecorder.In order to enhance the display function and develop the function of the mixed display,the basic display function of Scopecorder is completed.4.expand the display function and develop the waveform analysis system.According to the analysis of a specific waveform,wave recorder developed by time,frames,edge search function is shown under this topic.Historical function can not only reappear real-time waveform,but also load waveform.The scaling function can scale the waveform and do not lose the waveform details.It can be implemented in real-time mode and loading file mode.The file function realizes the large capacity file storage function of the optional channel,frame number and storage depth,supports the hard disk record,develops the file loading function,and loads the file data according to the number of frames and time.This part combines the above functions to achieve the analysis of waveform data.
