Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The core of the application is to provide a server VGA display system, a control method, a device and a medium thereof.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
Fig. 2 is a structural diagram of a server VGA display system according to an embodiment of the present application, and as shown in fig. 2, the system includes, in addition to a BMC1, a front VGA interface 2, and a rear VGA interface 3: SWITCH chip 4, controller 5.
The first end of the SWITCH chip 4 is connected to the BMC1 and is configured to receive a VGA signal output by the BMC 1; the second end of the SWITCH chip 4 is connected with the front VGA interface 2 and the rear VGA interface 3 through a first line and a second line respectively, and is used for sending VGA signals to the front VGA interface 2 or the rear VGA interface 3 through corresponding lines; the third end of the SWITCH chip 4 is connected with the controller 5;
the controller 5 is connected with the front VGA interface 2 and the rear VGA interface 3, and is configured to receive the feedback signals sent by the front VGA interface 2 and the rear VGA interface 3, and control the SWITCH chip 4 to SWITCH on the corresponding line according to the feedback signals.
It should be noted that in the specific implementation, there are many Complex Programmable Logic Devices (CPLDs) on the server motherboard, and the controller 5 in this embodiment may use the CPLDs existing on the motherboard.
The feedback signal sent by the VGA interface represents whether the VGA interface is connected with a display device or not. By default, if the VGA interface is connected to the display device, its feedback signal is high level, and if the VGA interface is not connected to the display device, its feedback signal is low level. The CPLD controls the SWITCH chip 4 to conduct the corresponding line by receiving the feedback signal. The SWITCH chip 4 obtains the VGA signal from the BMC 1. The SWITCH chip 4 has two outputs respectively connected with the front VGA interface 2 and the rear VGA interface 3, and each line is controlled to be opened or closed by the CPLD. For example, if the feedback signal output by the front VGA interface 2 is at a high level and the feedback signal output by the rear VGA interface 3 is at a low level, the CPLD turns on the first line of the SWITCH chip 4 according to the feedback signal and turns off the second line, so that the VGA signal is transmitted to the front VGA interface 2 through the first line.
The server VGA display system that this application embodiment provided, including BMC, leading VGA, rear VGA still includes: SWITCH chip and controller. The first end of the SWITCH chip is connected with the BMC and is used for receiving VGA signals output by the BMC; the second end of the SWITCH chip is respectively connected with the front VGA interface and the rear VGA interface through a first line and a second line, and is used for sending VGA signals to the front VGA interface or the rear VGA interface through corresponding lines; the third end of the SWITCH chip is connected with the controller; the controller is connected with the front VGA interface and the rear VGA interface and used for receiving feedback signals sent by the front VGA interface and the rear VGA interface and controlling the SWITCH chip to conduct corresponding lines according to the feedback signals. Compared with the prior art, the BMC transmits the VGA signal to the two VGA interfaces, the display equipment is connected with one VGA interface to display a picture, and the other VGA interface is vacant to cause abnormal resolution of the displayed picture. By adopting the technical scheme, the BMC transmits the VGA signal to the SWITCH chip, the controller controls the SWITCH chip to only conduct the corresponding line according to the feedback signal sent by the front VGA interface and the rear VGA interface, so that the VGA signal is only transmitted to the corresponding VGA interface through the corresponding line, and no VGA signal exists on the other VGA interfaces, thereby avoiding the attenuation or interference of the VGA signal caused by the vacant position of another VGA interface, and further improving the display resolution.
In specific implementation, due to the limitations of the environment, the site and the like of the server, operation and maintenance personnel sometimes need to use the front VGA interface 2 and sometimes need to use the rear VGA interface 3 to meet the operation and maintenance requirements under different conditions. Therefore, in order to facilitate the operation of the operation and maintenance staff, on the basis of the foregoing embodiment, in this embodiment, the server VGA display system further includes:
UID button 6;
the UID button 6 is connected with the controller 5, and the controller 5 is used for controlling the SWITCH chip 4 to conduct the corresponding line according to the feedback signal and the duration time of the key signal output by the UID button 6.
Note that the UID button 6 in this embodiment is an existing button on the server motherboard, and this button is generally used to locate a server. In the present embodiment, the user can output a key signal by controlling the UID button 6. The UID button 6 is connected with the controller 5, so that the controller 5 can control the SWITCH chip 4 to conduct the corresponding line according to the feedback signal and the duration of the UID button 6 controlled by a user. It will be appreciated that the control logic required by the controller 5 to combine the feedback signal with the duration of the key signal output by the UID button 6 should be active when both the front VGA interface 2 and the rear VGA interface 3 are connected to a display device, i.e. the outputs of the front VGA interface 2 and the rear VGA interface 3 are high. For example, the front VGA interface 2 and the rear VGA interface 3 are both at low level, which indicates that neither the front VGA interface 2 nor the rear VGA interface 3 is connected to a display device, VGA signals cannot be output, and at this time, the key signal output by the UID button 6 is invalid. Or the feedback signals of the front VGA interface 2 and the rear VGA interface 3 are high and low, which indicates that only one of the front VGA interface 2 and the rear VGA interface 3 is connected with the display device, the VGA signals can only be transmitted to the display device, and the key signal output by the UID button 6 at this time is invalid. When the front VGA interface 2 and the rear VGA interface 3 both output high levels, the fact that the front VGA interface 2 and the rear VGA interface 3 are both connected with the display device is shown, and at the moment, the front VGA interface 2 or the rear VGA interface 3 can be selected to be used according to the duration of the key signal output by the UID button 6.
According to the VGA display system of the server, the UID button is additionally arranged, so that the output line of the SWITCH chip can be switched according to the current requirements of a user.
Fig. 3 is a flowchart of a control method of a server VGA display system according to an embodiment of the present application, and the control method is applied to a SWITCH chip, where the SWITCH chip is connected to a BMC, a controller, a front VGA interface, and a rear VGA interface, as shown in fig. 3, the method includes:
s10: and receiving the VGA signal output by the BMC.
S11: the corresponding lines are conducted through the controller according to signals output by feedback signals of the front VGA interface and the rear VGA interface; wherein the lines include a first line and a second line.
S12: and transmitting the VGA signal to a front VGA interface or a rear VGA interface through a corresponding line.
Since the above embodiment describes the interaction between the SWITCH chip and other devices in detail, this embodiment is not described again.
The control method of the server VGA display system provided by the embodiment of the application is applied to the SWITCH chip, wherein the SWITCH chip is connected with the BMC, the controller, the front VGA interface and the rear VGA interface. In the method, a first end of a SWITCH chip is connected with a BMC and is used for receiving VGA signals output by the BMC; the second end of the SWITCH chip is respectively connected with the front VGA interface and the rear VGA interface through a first line and a second line, and is used for sending VGA signals to the front VGA interface or the rear VGA interface through corresponding lines; the third end of the SWITCH chip is connected with the controller; the controller is connected with the front VGA interface and the rear VGA interface and used for receiving feedback signals sent by the front VGA interface and the rear VGA interface and controlling the SWITCH chip to conduct corresponding lines according to the feedback signals. Compared with the prior art, the BMC transmits the VGA signal to the two VGA interfaces, the display equipment is connected with one VGA interface to display a picture, and the other VGA interface is vacant to cause abnormal resolution of the displayed picture. By adopting the technical scheme, the BMC transmits the VGA signal to the SWITCH chip, the controller controls the SWITCH chip to only conduct the corresponding line according to the feedback signal sent by the front VGA interface and the rear VGA interface, so that the VGA signal is only transmitted to the corresponding VGA interface through the corresponding line, and no VGA signal exists on the other VGA interfaces, thereby avoiding the attenuation or interference of the VGA signal caused by the vacant position of another VGA interface, and further improving the display resolution.
Fig. 4 is a flowchart of another control method for a VGA display system of a server according to an embodiment of the present application, and the control method is applied to a controller, where the controller is connected to a front VGA interface, a rear VGA interface, and a SWITCH chip, as shown in fig. 4, the method includes:
s20: and acquiring feedback signals of the front VGA interface and the rear VGA interface.
S21: controlling the SWITCH chip to conduct the corresponding line according to the feedback signal so as to transmit the VGA signal output by the BMC to the front VGA interface or the rear VGA interface through the line; wherein the lines include a first line and a second line.
Since the above embodiments describe the interaction between the controller and other devices in detail, the description of the embodiments is omitted.
The control method of the VGA display system of the server is applied to the controller, wherein the controller is connected with the front VGA interface, the rear VGA interface and the SWITCH chip. In the method, a first end of a SWITCH chip is connected with a BMC and is used for receiving VGA signals output by the BMC; the second end of the SWITCH chip is respectively connected with the front VGA interface and the rear VGA interface through a first line and a second line, and is used for sending VGA signals to the front VGA interface or the rear VGA interface through corresponding lines; the third end of the SWITCH chip is connected with the controller; the controller is connected with the front VGA interface and the rear VGA interface and used for receiving feedback signals sent by the front VGA interface and the rear VGA interface and controlling the SWITCH chip to conduct corresponding lines according to the feedback signals. Compared with the prior art, the BMC transmits the VGA signal to the two VGA interfaces, the display equipment is connected with one VGA interface to display a picture, and the other VGA interface is vacant to cause abnormal resolution of the displayed picture. By adopting the technical scheme, the BMC transmits the VGA signal to the SWITCH chip, the controller controls the SWITCH chip to only conduct the corresponding line according to the feedback signal sent by the front VGA interface and the rear VGA interface, so that the VGA signal is only transmitted to the corresponding VGA interface through the corresponding line, and no VGA signal exists on the other VGA interfaces, thereby avoiding the attenuation or interference of the VGA signal caused by the vacant position of another VGA interface, and further improving the display resolution.
In specific implementation, due to the limitations of the environment, the site and the like of the server, operation and maintenance personnel sometimes need to use a front VGA interface and sometimes need to use a rear VGA interface to meet the operation and maintenance requirements under different conditions. Therefore, in order to facilitate the operation of the operation and maintenance staff, on the basis of the above embodiment, in this embodiment, the controller is further connected to the UID button, and before the step of controlling the SWITCH chip to turn on the corresponding line according to the feedback signal, the method further includes:
if the feedback signals are all high level signals, acquiring the duration of a key signal output by the UID button;
further, controlling the SWITCH chip to conduct the corresponding line according to the feedback signal includes:
and controlling the SWITCH chip to conduct the corresponding line according to the duration of the key signal.
It can be understood that, in the specific implementation, if the front VGA interface and the rear VGA interface are both low level, it indicates that neither the front VGA interface nor the rear VGA interface is connected to the display device, the VGA signals cannot be output, and the key signal output by the UID button is invalid at this time. When the feedback signals of the front VGA interface and the rear VGA interface are high, the feedback signals of the front VGA interface and the rear VGA interface are low, that is, only one interface of the front VGA interface and the rear VGA interface is connected with the display equipment is indicated, the VGA signals can only be transmitted to the display equipment, and the key signals output by the UID button at the moment are invalid. When the front VGA interface and the rear VGA interface output high levels, the front VGA interface and the rear VGA interface are connected with the display equipment, and at the moment, the front VGA interface or the rear VGA interface can be selected to be used according to the duration of the key signal output by the UID button.
According to the control method of the VGA display system of the server, when the feedback signals are all high-level signals, the duration time of the key signals output by the UID button is obtained, so that the output lines of the SWITCH chip are switched according to the current requirements of a user, and the SWITCH chip is controlled to be connected with the corresponding lines.
On the basis of the foregoing embodiment, this embodiment further provides a specific control method for controlling the SWITCH chip to turn on the corresponding line according to the duration of the key signal, where the method includes:
and if the duration time of the key signal is less than or equal to the first preset time, controlling the circuits of the SWITCH chip to be all turned off.
It can be understood that when the duration of the key signal output by the maintenance personnel controlling the UID button is less than or equal to the first preset time, which indicates that it is not desirable to display the VGA signal through the display device, the controller turns the signal inside at this time, so that the VGA signal is not output.
According to the control method of the VGA display system of the server, when operation and maintenance personnel do not need to obtain VGA signals through display equipment, the duration time of the UID button is controlled, signals inside the controller are turned over, two output lines of the SWITCH chip are turned off, and non-output of the VGA signals is achieved.
On the basis of the above embodiment, in this embodiment, controlling the SWITCH chip to turn on the corresponding line according to the duration of the key signal includes:
and if the duration time of the key signal is longer than the first preset time and shorter than the second preset time, controlling the SWITCH chip to conduct the first line so as to transmit the VGA signal output by the BMC to the front VGA interface through the first line.
According to the control method of the server VGA display system, when the controller detects that the duration time of the key signal is longer than the first preset time and shorter than the second preset time, the SWITCH chip is controlled to be connected with the first line, the VGA signal is transmitted to the display equipment through the front VGA interface, and therefore the situation that the rear VGA interface of the server is jammed and operation and maintenance personnel need to use the front VGA interface is met.
On the basis of the above embodiment, in this embodiment, controlling the SWITCH chip to turn on the corresponding line according to the duration of the key signal includes:
and if the duration time of the key signal is greater than or equal to a second preset time, controlling the SWITCH chip to conduct a second line so as to transmit the VGA signal output by the BMC to the rear VGA interface through the second line.
According to the control method of the server VGA display system, when the controller detects that the duration time of the key signal is longer than or equal to the second preset time, the SWITCH chip is controlled to be connected with the second line, the VGA signal is transmitted to the display equipment through the rear VGA interface, and therefore the conditions that the front VGA interface of the server is jammed and operation and maintenance personnel need to use the rear VGA interface are met.
It is understood that, in the above embodiments, the front VGA interface or the rear VGA interface may be interchangeably selected according to the duration of the key signal, except for the above mentioned cases, in other embodiments, the SWITCH chip may be controlled to conduct the second line when the duration of the key signal is greater than the first preset time and less than the second preset time, and the SWITCH chip may be controlled to conduct the first line when the duration of the key signal is greater than or equal to the second preset time.
The first preset time and the second preset time in the above embodiments may be set by a technician, and both the values and the difference between the values should be avoided to be too large or too small when the first preset time and the second preset time are set. For example, the first preset time is set to 4s, the second preset time is set to 10s, in the above embodiment, when the duration of the key signal is less than or equal to 4s, none of the VGA interfaces outputs, the VGA signal is output by the front VGA interface between 4s and 10s, and the VGA signal is output by the rear VGA interface when greater than or equal to 10 s. It can be understood that if the first preset time and the second preset time are set too small or too large, a technician cannot clearly judge the key pressing time, and misoperation is easily caused.
In the foregoing embodiments, detailed descriptions are given to a server VGA display system and a control method thereof, and the application also provides embodiments corresponding to a control device of the server VGA display system. It should be noted that the present application describes the embodiments of the apparatus portion from two perspectives, one from the perspective of the function module and the other from the perspective of the hardware.
