Abstract

The invention relates to a digital display circuit in a dual-machine KVM sharer, belonging to the field of KVM sharer display and self-adaptive control circuits used in traffic management systems in civil aviation. The system includes a processor MCU, a first multiplexer, a second multiplexer, a display and a host graphics card connected to the second multiplexer, the first multiplexer, the second multiplexer The multiplexer, display and host graphics card are all connected to the output interface of the processor MCU, the first multiplexer is connected to the second multiplexer, and the display is connected to the first multiplexer and the second multiplexer device. The invention realizes the self-adaptive output of the display resolution of the dual-machine KVM sharer in the case of "opening", realizes the compatible display of various DVI interface displays, and satisfies the needs of civil aviation control for KVM display self-adaptation. The problem in the prior art that KVM sharers cannot be compatible with different types of displays is solved.

Description

technical field [0001] The invention relates to the field of KVM sharer display and self-adaptive control circuit applied in the traffic management system of civil aviation, in particular to a digital DVI "squeeze open" display circuit in a dual-machine KVM sharer. Background technique [0002] KVM is an acronym for the words Keyboard (keyboard), Mouse (mouse), and Video (video). A KVM sharer is a computer peripheral device that enables multiple computer hosts to share a set of keyboards, mice, and monitors. It switches between each computer host by pressing a hot key on the keyboard. Because there are many interfaces for computer keyboards, mice, and monitors, there are various forms of KVM sharers. The common keyboard and mouse interfaces are: PS / 2 interface and USB interface; the display interface is also divided into analog and digital. Common Common analog signal display interfaces include VGA interface and 5BNC interface. Common digital signal display interfaces inclu...
