Programmable virtual keyboard detection device and method

Abstract

The invention relates to a programmable virtual keyboard detection device. The device comprises a control module, a relay module, a download communication module, a keyboard output module, a computerfor programming, a touch screen display module and a power module; the control module is used for achieving storing and reading of downloaded operation instructions and controlling corresponding keyboard output and relay output according to an operation of a tester on a touch screen; the relay module conducts connection and disconnection according to the operation instructions and is used for conducting starting up and shutdown operations on to-be-tested equipment; the download communication module is responsible for a series operation instructions sent by the computer for programming; the keyboard output module is responsible for sending a keyboard instruction according to PS2 and USB protocols; the touch screen display module is used for displaying currently downloaded operation instructions, currently executed instructions, keyboard equipment output modes and the like and an operation of the tester on the touch screen is read; the power module provides working voltage.

Description

technical field [0001] The invention relates to an instrument equipment testing technology, in particular to a programmable virtual keyboard testing device and method. Background technique [0002] In large instruments and weapon systems, most of the general-purpose computer keyboards are used as user input devices. During the research and development of equipment, long-term continuous work is usually used to test the working effect or verify the reliability of the current equipment. During this test, the work of the device under test is usually controlled by manual input or setting input commands from within the program. [0003] Using manual input means that multiple testers need to repeat the work for a long time, and the long-term repeated operation of the testers may cause the equipment under test to face the hidden danger of unsafe wrong operation. For more sophisticated instruments or equipment An unsafe operation may mean huge losses. However, using the method of ...

AI Technical Summary

Problems solved by technology

However, it may be inconvenient to change the work order to be tested in real time by using the method of setting the input command inside the program, and sometimes it may not be convenient to set the work order in advance for the device under test

On the other hand, loading input from inside the program means that the communication program and hardware structure of the keyboard input part of the device under test have not participated in the current long-term repetitive work, and it is impossible to test whether there are hidden dangers in this part, nor can it be better simulating actual working conditions
