Embodiment Construction

[0022] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] The present invention realizes the graphical playback of multi-channel discrete quantities and the hardware basis of GJB289A bus data including the industrial computer of PXI bus, 2 pieces of 1553 board cards and 3 pieces of discrete quantity acquisition cards (each discrete quantity card can collect 96 signals), hardware It supports the monitoring of 2 GJB289A buses and the collection of 288 discrete signals. In practical applications, users can select the number of bus signals and discrete signals according to their needs.

[0024] The graphic playback multi-channel discrete quantity and GJB289A bus data method provided by the present invention first collects and stores the discrete quantity signal and the GJB289A bus data to be monitored in real time; then selects the signal to be displayed, and searches to form a text playback file...

Abstract

The invention relates to a method for graphical playback of discrete magnitude signals and GJB289A bus data and belongs to the technical field of waveform display processing. The method includes the steps that firstly, the discrete magnitude signals to be monitored and the GJB289A bus data to be monitored are acquired and stored in real time; secondly, signals needing to be displayed are selected, and retrieval is conducted to form a text playback file of the selected signals; finally, waveform display parameters are set according to content in the text playback file, and a DrawWaveform play function is called according to the display parameters for conducting waveform play on the text playback file. According to the method, a user can synchronously monitor multiple paths of discrete signals and the GJB289A bus data more visually and conveniently than the past, debugging testing personnel and maintenance personnel are helped to judge the working conditions of a system more accurately and rapidly, debugging and troubleshooting work efficiency is improved, troubleshooting is quickened, and normal work of the system is guaranteed.

Description

technical field [0001] The invention relates to a method for graphically replaying discrete quantities and GJB289A bus data, belonging to the technical field of waveform display processing. Background technique [0002] Existing data playback is mainly for the monitoring and playback of the same signal, or the acquisition and playback of discrete signals, or for the monitoring and playback of GJB289A bus signals, without putting the two signals together for synchronous comparison and display; the current general GJB289A bus signal monitoring Playback is mostly in the form of text rather than graphics; the number of discrete signals monitored by a standard oscilloscope is limited, usually less than 3 signals, and the waveform displayed is only the waveform of the current screen capture time; usually the data waveform played back by the software does not implement the player function, you cannot choose to stop viewing waveforms at any time and period within the recording time ...
