Keyboard input method of control system display control terminal

Abstract

The invention provides a keyboard input method of a control system display control terminal. According to the method, small keyboard physical keys, user function interface soft keys of the display control terminal and a mapping module are included, and the method comprises the steps that when the small keyboard physical keys are pressed, a key-pressing event is triggered, when the key trigger time at two times is longer than 300ms, the mapping module reads tab information of a main interface, the pressed key value code is scanned, the soft keys corresponding to the pressed key value are analyzed through the mapping module, the key attribute is changed to be true from acquiescent false, a static value change event is triggered, and the corresponding function trigger is achieved. The keyboard input method has the advantages that the defect that due to the facts that the space size is restrained, and the number of the small keyboard physical keys is limited, the multifunctional operation requirement of a user for the control system display control terminal cannot be met is overcome, reuse and expanding of the small keyboard physical keys is achieved, and the real-time man-machine interaction of a complex control system is completed.

Description

technical field [0001] The invention relates to a keyboard input method, in particular to a keyboard input method for a display and control terminal of a control system. Background technique [0002] As the display and control terminal of the horizontal loading vehicle control system, the main control computer of the horizontal loading vehicle is used to realize the functions of propulsion control, centering control, calibration, configuration query, and historical data query of the horizontal loading vehicle. Among them, the propulsion control process includes forward, backward, stop, grabbing, releasing, fast and slow selection; the centering control process includes automatic centering, distributed centering, manual centering, and automatic return to the sub-step selection. Due to the actual control steps and interface switching requirements, the number of physical keys of the small keyboard F1-F6 cannot meet the actual usage requirements. For the above-mentioned control...
