Detailed Description

The following is a further detailed description of preferred embodiments with reference to the accompanying drawings.

The invention provides a screen menu type adjusting method based on an input and output integrated system, namely an OSD (on screen display) realizing method based on a KVM (keyboard video mouse) integrated system. As shown in fig. 1, the KVM integrated system includes a KVM integrated device 1, a keyboard 3, a display 2, and a mouse 4 electrically connected to the KVM integrated device 1, and at least one computer terminal 5, where the KVM integrated device provides a keyboard interface, a display interface, and a mouse interface for each computer terminal, the keyboard interface, the display interface, and the mouse interface of the computer terminal 5 are respectively and correspondingly electrically connected to the keyboard interface, the display interface, and the mouse interface of the KVM integrated device 1, and input and output information control of each computer terminal 5 is implemented by the KVM integrated device 1. As shown in fig. 2, the KVM integrated apparatus 1 is provided with a KVM control circuit board 11 including an input-output micro control unit, and the display 2 is provided with a display control circuit board 21 including a display micro control unit. The KVM control circuit board 11 is electrically connected to the display control circuit board 21. in the preferred embodiment of the present invention, the KVM control circuit board 11 is electrically connected to the display control circuit board 21 by an RS232 interface.

As shown in fig. 3, the display control circuit board 21 processes OSD data as follows under the control of the display micro-control unit,

A1. as shown in the flow 2101 shown in fig. 3, the display 2 is turned on, and the display control circuit board 21 is powered on for initialization;

A2. as shown in the flow 2102 of fig. 3, send "Ready" signal to the KVM control circuit board 11; the Ready signal corresponds to the flow 1103 to 1104 in fig. 4, the KVM controller 11 is default to send the display data to the monitor controller 21 in the locked state to prevent the OSD data from being sent to the monitor controller 21 until waiting for the "Ready" signal from the monitor controller 21 to release the locked state to allow the OSD data to be sent to the monitor controller 21;

A3. as shown in the flow 2103 of fig. 3, when receiving an OSD request, determining a request initiating end, which is to perform a hierarchical processing on the OSD display and the request thereof at the computer terminal system end, the display control circuit board end and the KVM control circuit board end, in the preferred embodiment of the present invention, the OSD display and the request thereof at the computer terminal system end are taken as the highest priority, and the OSD display and the request thereof at the display control circuit board end and the KVM control circuit board end are taken as the lower priority;

when the OSD request initiating end is determined to be the computer terminal system end, step a4 is performed, i.e., flow 2104 shown in fig. 3;

when the OSD request initiating end is determined to be the display end, the step a5 is performed, that is, the flow 2108 shown in fig. 3;

when the OSD request initiator is determined to be the KVM controller board, go to step a6, i.e., flow 2111 shown in fig. 3;

A4. as shown in the process 2104 of fig. 3, a "Sleep" signal, i.e., a "Sleep" signal, is sent to the KVM control board, and the process is shifted to the process 1110 corresponding to the process 1105 shown in fig. 4, where the KVM control board will process according to the process 1110 to the process 1111, since the step a4 is the OSD process of the computer terminal system with the highest priority, it is necessary to prevent the KVM control board from sending OSD data, and the KVM control board receives the "Sleep" signal and sets the sending of display data to the display control board 21 to be in a locked state to prevent the sending of OSD data to the display control board 21;

as shown in the process 2105 of fig. 3, after the process 1111 of fig. 4 is completed, a "execute sleep" signal fed back from the KVM controller is received, indicating that the KVM controller does not send OSD data;

as shown in the flow 2106 of fig. 3, after the screen clearing is performed, OSD display is performed according to data from the computer terminal system;

as shown in the flow 2107 of fig. 3, after the OSD display is completed, step a2 is performed, i.e., the flow 2102 of fig. 3 is performed, and the process returns to step a2 to unlock the lock state of the KVM controller 11 for sending the display data to the monitor controller 21;

A5. as shown in the process 2108 of fig. 3, a "screen clear" signal, i.e. a "Clr" signal, is sent to the KVM control circuit board, and the process goes to the process 1109 corresponding to the process 1105 shown in fig. 4; because the OSD display priorities of the display end and the KVM control circuit board end are the same and lower than the highest priority of the OSD display of the computer terminal system end, the OSD display of the display end is allowed to be inserted into the OSD display of the KVM control circuit board end, and the OSD display of the KVM control circuit board end is also allowed to be inserted into the OSD display of the display end, therefore, when the OSD request of the display end exists, no matter whether the OSD data display of the KVM control circuit board end exists or not, the OSD display of the display end can be performed by clearing the screen;

as shown in the process 2109 of fig. 3, after the process 1109 of fig. 4 is completed, a "clear screen permission" signal fed back from the KVM control circuit board terminal is received;

as in the flow 2110 illustrated in fig. 3, after the screen is cleared, the OSD is displayed according to the data from the display, and the process returns to step a3, that is, the flow 2104 illustrated in fig. 3; unlike the step a4, the step a5 only needs to perform OSD display and then returns to the step A3, and does not need to return to the step a2 after the OSD display is completed in the step a4, which means that the OSD display priority at the display end is lower than that at the computer terminal system end;

A6. referring to the process 2111 of FIG. 3, a signal "permission to show" is sent to the KVM control board, the process flow is shifted 1106 to the process 1105 of FIG. 4, and after the process 2111 of FIG. 3, the process 1107 is performed at the KVM control board 11; because the OSD display priorities of the display end and the KVM control circuit board end are the same and lower than the highest priority of the OSD display of the computer terminal system end, when the OSD request of the KVM control circuit board end exists, no matter whether the OSD data of the display end is displayed or not, the OSD display of the KVM control circuit board end can be performed by clearing the screen;

as shown in the process 2112 of fig. 3, after the KVM controller 11 performs the process 1108 of fig. 4, and the monitor controller 21 performs screen clearing, the OSD display is performed according to the display data from the KVM controller, and the process returns to step a3, that is, the process 2104 of fig. 3; similarly, unlike step a4, step a6 only needs to perform OSD display and then returns to step A3, and does not need to return to step a2 after the OSD display is completed in step a4, which means that the priority of OSD display at the KVM control circuit board end is lower than that at the computer terminal system end;

on the KVM control board 11, as shown in FIG. 4, the KVM control board 11 processes the OSD data under the control of the input/output MCU as follows,

B1. as shown in the flow 1101 of fig. 4, the KVM integrated device 1 is powered on, and the KVM control circuit board 11 is powered on for initialization;

B2. as shown in the flow 1102 in fig. 4, it is configured to send display data to the display control circuit board end to enter a locked state, and wait for the "Ready" signal sent in the flow 2102 in fig. 3;

B3. as shown in the process 1103 in fig. 4, detecting the signal from the display control circuit board 21, and when receiving the "Ready" signal from the display control circuit board, as shown in the process 1104 in fig. 4, setting the display data to be sent to the display control circuit board to enter an on state, so as to enable the KVM integrated device to perform OSD display; when the "Ready" signal is not received from the display control circuit board, the process returns to the process 1103 until the "Ready" signal is received and the subsequent processes are performed;

B4. as shown in fig. 4, the KVM controller may process the received signals related to OSD display separately, to implement prioritized OSD display in cooperation with the display controller 21,

when there is an OSD command input, such as an OSD hot key input from the KVM integrated apparatus 1, step B5 is executed, i.e., the process 1105 shown in fig. 4 branches to a process 1106;

when receiving the "clear" signal, i.e., "Clr" signal, from the panel terminal of the display control circuit, indicating that there is an OSD display of the panel terminal of the KVM control circuit having the same priority as the OSD display of the panel terminal of the KVM control circuit, go to step B6, i.e., the flow 1105 shown in fig. 4 goes to the flow 1109;

when receiving the "Sleep" signal, i.e., the "Sleep" signal from the monitor control circuit board, indicating that the OSD display at the computer terminal system side with the highest priority needs to be prevented from sending OSD display data at the KVM control circuit board side to the monitor control circuit board 21, performing step B7, i.e., the process 1105 shown in fig. 4 turns to a process 1110;

b5; as shown in the flow 1106 of fig. 4, when there is an OSD command input, an OSD request is sent to the panel terminal of the display control circuit;

as shown in the flow 1107 in fig. 4, when a "display permission" signal fed back from the display control circuit board end is received after the flow 2111 in fig. 3, as shown in the flow 1108 in fig. 4, OSD display data is sent to the display control circuit board end, and OSD display is performed through the flow 2112 in fig. 3;

thereafter, return to step B4, i.e., flow 1105 of fig. 4;

B6. as shown in a flow 1109 in fig. 4, after an OSD request is sent from the display terminal, and after a flow 2108 in fig. 3, that is, after the display control circuit board 21 sends a "Clr" signal, a "clear screen permission" signal is fed back to the display control circuit board terminal, so that OSD display of the display terminals with the same priority can be performed;

thereafter, return to step B4, i.e., flow 1105 of fig. 4;

B7. as shown in the flow 1110 in fig. 4, after the flow 2104 in fig. 3, it is set to send display data to the display control circuit board end to enter a locked state, so as to prevent sending of OSD display data of itself;

the flow 1111 of fig. 4 feeds back the "execute sleep" signal to the panel side of the display control circuit;

returning to step B3, i.e. the flow 1103 in fig. 4, the "Ready" signal is sent after the display control circuit board 21 finishes processing the OSD display at the end of the computer terminal system with the highest priority.

The invention saves the hardware structure special for OSD display, coordinates the OSD display of the computer terminal system end, the display end and the KVM integrated equipment end, saves the cost and improves the data processing efficiency. The invention makes the OSD display of the display end and the OSD display of the KVM integrated equipment end as the same priority, the OSD display of the display end and the OSD display of the KVM integrated equipment end can be switched and displayed at any time, and the OSD display of the computer terminal system end and the OSD display of the KVM integrated terminal end are taken as the highest priority, thereby preventing the OSD display of the computer terminal system end and the OSD display of the KVM integrated terminal end from being mixed, being convenient for use and improving the operation efficiency of the OSD display.
