If the user would like to watch one of KVM switch PCs' monitor display data only, to click mouse on the chosen PC display or to use hot key control gets this chosen PC monitor full screen display data back from PCs' multi-screen display data and display the chosen PC full screen data on KVM console monitor.

Description

Computer automatic switch device capable of centrally managing and controlling power of multiple computers and simultaneously displaying screens of multiple computers to console screen and method thereof

The invention utilizes a computer automatic switch device with a screen display setting function to centrally manage the characteristics of a plurality of computers (screen/keyboard/mouse), and a USB interface is provided in the computer automatic switch device. The control unit or a plurality of USB ports control the power supply of the computer, and the power supply plugs the power supply to the computer connected to the automatic switch device of the computer. In the On Screen Display Menu, add the function that allows the computer to turn on the power, turn off the power, turn the power on and turn off the power periodically, and the user can display the screen by On Screen Display Menu. In the menu, directly switch the power supply command, select those computers to turn on the power, turn off the power, and when to turn the power on or off. The command controls the switching power supply of the computer through the USB interface added by the computer automatic switcher system management architecture to solve the problem that when the computer is down or the console is abnormal, the computer automatic switch device cannot use the console to make the machine or abnormal. The computer is back to normal operation. At this point, you can use the USB port of the computer's automatic switcher device to control the computer power strip to turn off the abnormal computer power, then turn on the power to restore the computer, or use the timing. Turn on the power and time off the power to reduce the computer's long-term idling power consumption and reduce the life of the computer equipment itself to achieve energy saving and carbon reduction and truly centralized management of multiple computers.

The screen display of the automatic switch device of the computer can not only display the computer screen corresponding to a single computer, but also display multiple computer screens connected to the automatic switch device of the computer at the same time on the screen of the console. In this way, you can see the operation status of all the computers at the same time. Once you want to control a computer separately, just use the keyboard hotkey of the computer automatic switch device to select the computer to be controlled or the mouse with the computer automatic switch device. To select one of the multiple screen displays, the selected screen will be enlarged to replace the existing screen displaying multiple computer screens, and then switch to a computer like the computer automatic switcher device. The general mode of operation.

The general skill is that the On Screen Display computer automatic switch device only shares the console (keyboard, mouse, display) of the connected computer, so that it does not need to be separate for each computer. The console saves space and time, solves the problem of using multiple console power supplies and reducing peripheral equipment to save money. However, this is limited to the basic operation and management of the control computer connected to the console connected to the automatic switch computer device. If the computer connected to the switch has a crash or an abnormality, causing the console of the automatic switch device to be inoperable, or when the computer is idling during non-use time, the best way to do this is to use the computer. The power is turned off or set to turn off its power at regular intervals. However, the automatic switch computer device in the workshop does not have the control function of turning on and off the power of the managed computer. In order to control the power on and off of the managed computer, it is necessary to operate independently of the computer switcher, for example, to use the network remote control power strip (PDU-Power). Distribution Unit) equipment to achieve the purpose of turning on and off the computer power, not only can not save the cost of the equipment, but also need to provide a centralized management software to operate and can not be integrated into the computer switch itself is used to control multiple computers. The basic characteristics of the console to make the convenience of true centralized management.

Because the console of the automatic switcher computer device only displays a single computer, when the connected computer has abnormal conditions and sometimes it is not displayed on the screen of its console, the user will not be able to immediately perform the appropriate Disposal will delay the optimal time to handle the abnormal condition. How to make the screen of the automatic switch computer device can simultaneously display the status of all the computers on the same console display, which will be the desired demand of the current automatic switch computer device users.

In order to solve the conventional equipment, the inventor needs to perform the action of restarting the computer when the computer is down or working abnormally, or the computer needs to be temporarily turned off when the computer is idle to save power; and at the same time in the console screen At a glance, you can see the purpose of all connected computers. Therefore, based on years of experience, world trends and time-consuming research and development, the On Screen Display computer automatic switcher will be further improved. At this time, only the power control of the connected computer is placed on the computer automatic switch device. The display itself and the screen of the multiple computers are displayed on the console display at the same time, so that the user can know the operation status of all the computers at a glance, and the newly added functions are built into the automatic switch device of the computer.

The main purpose of the invention is to make the function of the computer switcher more complete and perfect, and conform to the trend of the times. It makes the user's centralized management of the computer more convenient, simpler, more time-saving, more efficient, and solves the problem of unnecessary power consumption.

On Screen Display The automatic switch device itself is used to centrally manage the console features of all connected computers. In the On Screen Display menu, add control computer power command options - -- Turn on the computer, turn off the computer, and turn the computer power on or off periodically, and send control power or energy-saving commands to the computer connected to the automatic switch, so that the control of the computer does not need to be controlled except the basic console control. Rely on the extra equipment to manage the computer power separately, to achieve a true centralized management of the computer, saving unnecessary costs.

The design of the computer automatic switch device can display the screen display of the console not only to display the computer screen corresponding to a single computer, but also to simultaneously display the multiple computer screens connected to the automatic switch device of the computer on the display of the console. On the screen, use the multi-split screen to display all or part of the computer screen connected to the computer's automatic switcher, so that you can see all the computer's operating status at the same time. By displaying the screen information of all the computers or some computers of the controlled computer at the same time in the console, it can effectively solve the abnormality of the computer and can be processed immediately. It does not need to use the traditional scanning method to monitor or use one computer. Screen switching to handle, once you want to control a computer separately, just use the keyboard hot key of the computer automatic switch device to select the computer to be controlled or use the mouse of the computer automatic switch device to point Selecting multiple screen displays to control a certain computer screen, the selected screen will be enlarged to replace the existing screen of multiple monitors, and return to the computer automatic switch device. Operation method. .
