Displayer picture switching response time test system and method

Abstract

The invention provides a displayer picture switching response time test system and method. The system comprises a displayer picture switching trigger, a displayer, a photosensitive probe, a photoelectric signal processor and a data collecting operation control unit, wherein the displayer picture switching trigger is used for sending operation instructions to displayer control equipment; the displayer is used for switching pictures under the control of the displayer control equipment, the photosensitive probe is used for collecting brightness of pictures of the displayer, and the photoelectric signal processor is used for outputting second switching value signals to the data collecting operation control unit in real time; the data collecting operation control unit is used for determining the time difference between a first received switching value signal and a second received same-time switching value signal to be the displayer picture switching response time when the second received same-time switching value signal and the second received last-time switching value signal are different. Compared with a manual method adopted for testing displayer picture switching response time in the prior art, the displayer picture switching response time test method has the advantages of improving test efficiency and test precision.

Description

technical field [0001] The invention relates to the field of computer testing, in particular to a display screen switching response time testing system and method. Background technique [0002] The distributed control system (Distributed Control Systems, DCS) has become the core system of the power plant, and whether the performance of the distributed control system is stable has become a key factor to measure whether the power plant can operate safely and stably. With the increasing scale and capacity of power plants, and the goal of digital and remote construction, a large number of smart devices and test points are connected to the DCS system for centralized control. At the same time, the integrated development idea of ​​power plant control incorporates the auxiliary control system into the control ring network of the entire DCS system, and even integrates the design and configuration of the electrical control system, DCS and fieldbus control systems. So many network dev...

AI Technical Summary

Problems solved by technology

[0007] 1) Both the start time of screen switching and the end time of screen switching need to be judged manually, and then reflected on the operation of the hand-held stopwatch. Compared with the minimum index of screen switching time, human reaction time is also delayed, so it is difficult to do accurate testing , so that the measured data cannot truly and accurately show the fast response performance of the DCS system operation interface

[0008] 2) The test efficiency is relatively low, and two people are required to coordinate and cooperate to complete the test operation
