Monitor console scheduling KVM switch system

Abstract

The invention provides a monitor console scheduling KVM switch system. The system is characterized by comprising a system host unit, a signal sending unit, a signal receiving unit and a KVM unit, wherein the system host unit edits and sends a display signal and keyboard and mouse signals; the signal sending unit sends the display signal and the keyboard and mouse signals to outside through an IP network; the signal receiving unit receives the display signal and the keyboard and mouse signals from the signal sending unit through the IP network; the KVM unit comprises a display, a keyboard and a mouse; the display receives the display signal and realizes corresponding control operation; and the keyboard and the mouse receive the keyboard and mouse signals and realize the corresponding control operation. According to the system, the purpose of enabling a scheduler to control all monitor hosts by use of a set of keyboard and mouse device when monitoring a plurality of display screens at the same time is achieved.

Description

technical field [0001] The invention relates to a KVM signal transmission technology, in particular to a KVM switch system of a dispatching and monitoring station. Background technique [0002] With the continuous deepening of the construction of the "big operation" system, the power grid dispatching monitors need to simultaneously monitor multiple systems such as the energy management system (EMS), dispatching error prevention system, video monitoring system, reactive power optimization system, and OMS system. control. The servers and workstations of each system are centrally installed in the automation room, and the monitor, keyboard, and mouse are extended to the dispatching and monitoring hall for remote use through KVM equipment. At present, the KVM method adopted by the company's dispatching and monitoring hall is a point-to-point method, that is, a server and a desktop device of a workstation extend from the computer room to each fixed seat in the dispatching and mon...

AI Technical Summary

Problems solved by technology

[0003] The existing problems of the current KVM system mainly lie in: 1) the KVM wiring is fixed, which is not easy to expand; 2) multiple sets of keyboards and mouse devices coexist, and there is a lack of economical, effective and reliable operation control methods; 3) each dispatcher monitor monitors The number of display screens is limited, which is difficult to meet the monitoring and use of all on-duty auxiliary systems; 4) There are too many KVM controllers, and the maintenance workload is heavy
