Among them, VGA is a computer display standard proposed by IBM in 1987 using analog signals. The server outputs display information through VGA interface, which is the special interface for computer to output data with VGA standard. The VGA interface is divided into 3 rows of 5 holes, the most widely used interface type is on the display card, and most of the display cards are provided with the interface. It transmits red, green, blue analog signals (horizontal and vertical signals).
In order to solve the above problems, a server display system is designed in an embodiment of the present invention, which is used to solve the problems of low display quality and no backup display in the current server architecture, optimize display quality, and improve system stability and reliability, and as shown in fig. 1, for example, the server display system includes a display control module, a front-back dual display module, a switching control module, and a display backup module, where the display control module includes: the dual display module includes DP Switch (DisplayPort Switch, display interface exchange) chip, and the switching control module includes: CP LD (Complex Programmable Logic Device ) chip, display back-up module includes: PCIE (Peripheral Component Interconnect Express, high-speed serial computer expansion bus standard) to DP chip; the display control module is used for converting display information transmitted by the central processing unit and the platform control center into DP signals to be output through the baseboard management controller; the front-back dual display module is used for dividing a DP signal output by the substrate management controller into two paths through the DP Switch chip and transmitting the two paths to the front window and the back window respectively; the switching control module is used for judging the state of the baseboard management controller through the complex programmable logic device, and transmitting the display information transmitted by the platform control center to the display backup module under the condition that the state of the baseboard management controller is abnormal; the display backup module is used for converting display information transmitted by the platform control center into DP signals through a PCIE-DP conversion chip, wherein DP is a digital video interface standard standardized by the Consortium of PC and chip manufacturers, VESA (Video Electronics Standards Association ). The interface is free of authentication and authorization, is mainly used for connecting a video source with devices such as a display and the like, and also supports carrying audio, USB and other forms of data. The interface is designed to replace the conventional VGA, DVI and FPD-Link (LVDS) interfaces. The interface is backward compatible with legacy interfaces (e.g., HDMI and DVI) through active or passive adapters.
According to the server display system provided by the embodiment of the invention, through the arrangement of the display backup module and the switching control module, when the problem of the substrate management controller is detected, the PCIE of the display backup module is converted into the DP chip to realize front and rear dual display of the server, so that the common problems of incapability of displaying and the like caused by the abnormality of the substrate management controller are avoided, the dependence on the substrate management controller is reduced, and the stability and the reliability of the system are improved. In addition, the embodiment of the invention does not use the traditional VGA as a system display scheme, uses the DP supported by the current baseboard management controller, compared with VGA signals, the DP signals can improve the resolution of system display, and simultaneously do not use VGA buffer as a front-back dual-display implementation scheme, and uses a DP Switch chip scheme, thereby avoiding the problems of unclear dual-display images, ghost images and other display image quality which are currently encountered.
Referring to fig. 2, one of the step flowcharts of the server display method provided by the embodiment of the present invention is shown, where the method may include:
Step 101, receiving a watchdog signal of a baseboard management controller through a complex programmable logic device.
In the embodiment of the invention, the baseboard management controller converts the received display information into DP signal transmission under the normal state, but in order to reduce the dependence on the baseboard management controller, a display backup module is arranged, and the effect of converting the display information into DP signal transmission can be realized, but the conversion is executed when the baseboard management controller has a problem, so that a complex programmable logic device is arranged to receive the watchdog signal of the baseboard management controller, thereby determining the state of the baseboard management controller.
Step 102, analyzing the watchdog signal to obtain the state of the baseboard management controller.
The watchdog signal in the embodiment of the invention carries information about the state of the baseboard management controller, so that after the watchdog signal of the baseboard management controller is received by the complex programmable logic device, the signal is analyzed to determine the state of the baseboard management controller.
The Watchdog, also called a watch, is essentially a timer circuit, and generally has an input and an output, wherein the input is called a feed dog, and the output is generally connected to the reset terminal of the other part, and is generally connected to the singlechip. The function of the watchdog is to periodically check the internal condition of the chip and send a restart signal to the chip once an error occurs. For example, in the embodiment of the present invention, if the baseboard management controller is abnormal, for example, if the chip is dead, a restart signal is sent to the complex programmable logic device chip, and whether the baseboard management controller is abnormal is determined by whether the restart signal is received.
Step 103, if it is determined that the state of the baseboard management controller is normal, transmitting a PCIE signal carrying the target display information to the baseboard management controller, so that the baseboard management controller realizes front and rear dual display of the server.
In the embodiment of the invention, when the normal operation of the baseboard management controller is detected, the switching chip transmits PCIE signals carrying target display information to the baseboard management controller, and then the signals are transmitted to the front and rear dual display modules of the server after being processed by the baseboard management controller to realize front and rear dual display of the server.
It should be noted that, in order to avoid poor transmission resolution and unstable signal transmission of VGA signals, in the embodiment of the present invention, DP signal transmission is used, that is, a PCIE signal carrying target display information is converted into a DP signal by the baseboard management controller and then sent to a front-back dual display module, because only one path of DP signal is used at this time, in order to realize normal display of a front window and a rear window, one path of DP signal output by the baseboard management controller needs to be divided into two paths by a DP switch chip in the front-back dual display module, and according to a specific system scheme, the two paths of signals are respectively connected to corresponding connectors and then connected to corresponding front/back corresponding sub-cards, or directly connected to a DP connector on a motherboard, so as to realize front-back dual display of the server, where the specific implementation steps include:
If the state of the baseboard management controller is normal, transmitting PCIE signals to the baseboard management controller;
converting target display information carried by the PCIE signal into a first DP signal through the baseboard management controller;
transmitting the first DP signal to the DP switch chip;
expanding the first DP signal into a first sub DP signal and a second sub DP signal through a DP switch chip;
the first sub DP signal and the second sub DP signal are respectively sent to a front window and a rear window of the server, so that front and rear double display of the server is realized, and the method comprises the following steps:
the front and rear double display of the server is realized by respectively connecting the first sub-DP signal and the second sub-DP signal to the DP connector of the main board, or respectively connecting the first sub-DP signal and the second sub-DP signal to the DP connector of the main board and then respectively receiving the front/rear sub-card, and respectively transmitting the first sub-DP signal and the second sub-DP signal to the front window and the rear window of the server.
The target display information is converted into the DP signal by using the substrate management controller, compared with the VGA signal, the resolution of system display is improved, and meanwhile, the expansion of the DP signal is realized by using the DP switch chip, so that the display image quality problems of unclear double-display images, ghost images and the like in the prior art are avoided.
Step 104, if it is determined that the status of the baseboard management controller is abnormal, transmitting the PCIE signal carrying the target display information to the PCIE to DP chip, so that the PCIE to DP chip realizes front and back dual display of the server.
In the embodiment of the invention, when the abnormal condition of the baseboard management controller is detected, and the baseboard management controller cannot work normally, the switching chip transmits PCIE signals carrying target display information to the PCIE-DP conversion chip, at the moment, the PCIE-DP conversion chip analyzes the signals and then sends the signals to the front and rear dual-display module, and one path of DP signals output by the PCIE-DP conversion chip is divided into two paths by the DP switch chip in the front and rear dual-display module and is respectively transmitted to the front window and the rear window of the server, so that front and rear dual-display of the server is realized.
It should be noted that, after determining that the state of the baseboard management controller is abnormal, transmitting the PCIE signal carrying the target display information to the PCIE to DP chip to output the DP signal, before inputting the DP signal into the DP switch, a switching chip is further required to switch the current DP signal, because there may be a case that the baseboard management controller has no problem when converting the DP signal, but when transmitting the DP signal to the DP switch chip of the front and rear dual display module, an abnormality occurs, if at this time, the DP switch chip still transmits the DP signal through the baseboard management controller according to the determination result of the previous step, the DP signal cannot be received at this time, and therefore cannot be displayed, so after each transmitted node needs to set a switching chip for determining and switching, after converting the target display information into the DP signal, a switching chip is still set when transmitting the DP signal to the DP switch chip, and when determining that the baseboard management controller is abnormal, the output DP signal is continuously transmitted to the DP switch chip through the PCIE to implement the following steps:
Converting target display information carried by the PCIE signal into a second DP signal through the PCIE-to-DP chip;
and transmitting the second DP signal to a second switching chip.
The DP is a digital video interface standard standardized by the video electronics standards institute (VES a) developed by the PC and chip manufacturer association. The interface is free of authentication and authorization, is mainly used for connecting a video source with devices such as a display and the like, and also supports carrying audio, USB and other forms of data. The interface is designed to replace the conventional VGA, DVI and FPD-Link (LVDS) interfaces. The interface is backward compatible with legacy interfaces (e.g., HDMI and DVI) through active or passive adapters. According to the invention, the switching chip is arranged at each node for transmitting signals, so that no matter which transmission node has a problem, the transmission line can be switched in time by switching the PCIE from the PCIE to the DP of the display backup module, the display work of the system is taken over, the common problems that the display cannot be performed due to the abnormality of the substrate management controller and the like are avoided, the normal transmission of target display information is ensured, and the stability and the reliability of the system are improved.
To sum up, as shown in fig. 3, a second step flowchart of the server display method provided by the embodiment of the present invention is shown, the complex programmable logic device monitors the baseboard management controller by receiving the watchdog signal of the baseboard management controller, and when the baseboard management controller is determined to be normal, outputs a display interface (DP) signal to a display interface switching chip (DP Switch chip) through the baseboard management controller, and when the baseboard management controller is determined to be abnormal, switches the channel of the display signal, and uses a high-speed serial computer expansion bus standard-to-display interface (PCIE-to-DP) chip to output a display interface (DP) signal to the DP Switch chip.
The server display method provided by the embodiment of the invention comprises the following steps: the method and the device have the advantages that the watchdog signal of the baseboard management controller is received through the complex programmable logic device, the watchdog signal is analyzed, the state of the baseboard management controller is obtained, if the state of the baseboard management controller is determined to be normal, the PCIE signal carrying the target display information is transmitted to the baseboard management controller, so that the baseboard management controller can realize front and rear double display of the server, if the state of the baseboard management controller is determined to be abnormal, the PCIE signal carrying the target display information is transmitted to the PCIE-DP chip, so that the PCIE-DP chip can realize front and rear double display of the server.
Referring to fig. 4, a third step flowchart of a server display method according to an embodiment of the present invention is shown, and specifically includes:

And 203, acquiring PCIE signals carrying target display information, which are generated by interaction of the central processing unit and the platform control center.
After the central processor and the platform control center interact, the platform control center outputs a group of PCIE signals, the platform control center interconnects with the baseboard management controller through the PCIE signals, and meanwhile, display information to be transmitted is transmitted to the baseboard management controller through the PCIE signals, so that the PCIE signals generated by the interaction of the central processor and the platform control center carry target display information.
In step 204, the PCIE signal carrying the target display information is transmitted to the first switching chip, where the first switching chip supports the high-speed signal.
In the embodiment of the invention, the display backup module can be switched to in time when the substrate management controller is abnormal, so that a switching chip is arranged at each transmission node, namely, when the platform control center transmits PCIE signals carrying target display information to the substrate management controller, the PCIE signals carrying target display information are transmitted to a switching chip capable of supporting high-speed signals.
Step 205, the control signal of the first switching chip is connected to the complex programmable logic device.
The first switching chip in the embodiment of the invention is used for timely switching the transmission line when the abnormality of the baseboard management controller is detected, wherein the abnormality of the baseboard management controller is detected by the complex programmable logic device, so that the control signal of the first switching chip is connected to the complex programmable logic device.
In step 206, the PCIE signal is split into two paths by the first switching chip and is transmitted to the baseboard management controller and the PCIE-DP chip respectively.
In the embodiment of the invention, the first switching chip timely switches the transmission line when detecting that the substrate management controller is abnormal, wherein the lines capable of carrying out signal transmission are the substrate management controller and the PCIE-to-DP chip, so PCIE signals are divided into two paths and are respectively transmitted to the substrate management controller and the PCI E-to-DP chip.
Step 207, if it is determined that the status of the baseboard management controller is normal, transmitting a PCIE signal carrying the target display information to the baseboard management controller, so that the baseboard management controller realizes front and rear dual display of the server.
In the embodiment of the invention, when detecting that the substrate management controller is abnormal and can not work normally, the transmission path of the PCIE signal carrying the target display information is switched through the first switching chip, namely the PCIE signal carrying the target display information is transmitted to the PCIE-to-DP chip, and the specific implementation steps comprise:
If the state of the baseboard management controller is determined to be abnormal, the complex programmable logic device controls the first switching chip to switch the transmission path of the PCIE signal carrying the target display information through the accessed control signal;
and transmitting PCIE signals carrying target display information to the PCIE-DP chip so that the PCIE-DP chip realizes front and back double display of the server.
