For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of 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 apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

First, description is made of a video function in a conventional scheme: as shown in fig. 1, fig. 1 is a block diagram of a video function implementation in the related art, specifically, a host transmits video data to a VGA (Video Graphic Array, displaying a drawing array), then a first display end directly displays the video data in the VGA, a compression unit compresses the video data in the VGA, and the compressed video data is stored in a storage module, and a second display end is transmitted through an EMAC (Ethernet Media Access Controller ) to decompress and display the video data.

Secondly, the implementation of the video compression function in the conventional scheme is described: as shown in fig. 2, fig. 2 is a BLOCK diagram of video compression in the related art, the compression unit converts original video data output by the VGA into data in YUV format through a color space conversion module (RGB 2 YUV), then caches Y, U, V data with storage resources in a slice (FIFO (First Input First Output, first-in first-out queue)), and according to the requirement of BLOCK format conversion (supporting YUV444/YUV422/YUV420 compression format), 16 y_fifos, 16 u_fifos and 16 v_fifos are needed, and meanwhile according to project practice experience, for (1920 x 1200) with the maximum resolution, the depth of FIFO is 16384 and the width of 8bits, so that the condition that the FIFO is not full and the condition of no loss can be satisfied. The video_comp_ip in fig. 2 is used to implement a compression function, and YUV format data is obtained from the FIFO queue and compressed to obtain compressed data.

If the current compression mode is YUV422, the data is input to the Y data of 16×16 of the subsequent stage, then the data is input to the U data of 16×8, and then the data is input to the V data of 16×8. And then sequentially circulated. If the current compression mode is YUV444, the data is input to the Y data of the next stage 8×8, then the data of the U of 8×8 is input, and then the data of the V of 8×8 is input.

The traditional scheme has the following defects: the picture that the video display terminal shows is controlled by the host computer end completely, if the host computer end does not power on or does not start after the power on, then the host computer end can not output video data to base plate management control chip to can't transmit the data after handling to the video display terminal, lead to the video display terminal not have picture output, and then lead to human-computer interaction's experience to feel relatively poor. And the required on-chip storage space is very large and is up to 768KB, the area and cost control of a chip are very unfavorable, and meanwhile, the FIFO with very large quantity and capacity is very difficult to the time sequence constraint of the chip, the back-end design, the packaging manufacture and the like.

Referring to fig. 4, fig. 4 is a flow chart of a data processing method provided in the present application, the method is applied to a substrate management device, and preset image data is stored in the substrate management device in advance, and the method includes:

s11: determining whether video data sent by a host computer is received or not;

specifically, when the video display end can display a picture, a video picture corresponding to the video data sent by the host end is generally displayed, and when the host end does not send the video data, the video display end cannot display the picture. The case where the host side does not send video data may be: the application is not limited here, specifically according to the actual situation, because the host side is not powered on, the host side is powered on but the CPU (Central Processing Unit/Processor) is not started, the host side has a fault to cause that video data cannot be transmitted, or a transmission channel between the host side and the host side has a fault, etc.

Therefore, no matter what reason, as long as the video data sent by the host end cannot be received, the following step of obtaining the preset image data is performed, so that the video display end displays the preset image, and the situation that the video display end does not have picture output is avoided.

S12: if not, acquiring pre-stored preset image data;

specifically, after the video data sent by the host end is not received, the pre-stored preset image data is obtained, so that the video display end can display the preset image according to the preset image data.

When the method is applied to the substrate management device, the preset image data are stored in a storage module which can directly interact with the substrate management device. In addition, the preset image data in the present application may be image data (for example, the image data may be a trademark or a server complete machine information image or other images), or may be video data (for example, manufacturer's introduction video or server introduction video or slide show video including a plurality of image data, etc.).

S13: and transmitting the preset image data to the video display end so as to trigger the video display end to display the corresponding preset image according to the preset image data.

Specifically, after the preset image data is obtained, the preset image data is transmitted to the video display end, wherein the video display end may include at least one first display end and at least one second display end, the preset image data may be directly transmitted to the first display end, and at this time, the corresponding first display end may directly display the preset image based on the preset image data. When the preset image data is transmitted to the second display end, the preset image data is required to be compressed, the compressed data is transmitted to the second display end in a remote mode through a network, the second display end is triggered to decompress the compressed data, and the preset image is displayed according to the decompressed data.

In summary, the method in the application can obtain the pre-stored pre-set image data when the host end does not interact with the video data, so that the pre-set image is displayed on the video display end, no picture output of the video display end is avoided, and man-machine interaction experience is enhanced.

Based on the above embodiments:

as a preferred embodiment, triggering the video display terminal to display a corresponding preset image according to the preset image data includes:

Specifically, when the video display end displays the preset image, firstly, the resolution information corresponding to the preset image data is obtained, and then the preset image is displayed based on the obtained resolution information and the received preset image data. Specifically, but not limited to, the preset image DATA may be converted into a DVI (Digital Visual Interface, digital video interface) timing sequence (the DVI timing sequence at least includes signals such as HS/VS/data_en) according to the resolution information, and then the DVI timing sequence is digital-to-analog converted and then connected to a VGA interface of the video display end to display the corresponding preset image.

As a preferred embodiment, the pre-stored preset image data is acquired; transmitting the preset image data to the video display end to trigger the video display end to display the corresponding preset image according to the preset image data, comprising:

when the preset image data is image data, circularly acquiring the image data, and sending the acquired image data to a video display end so as to trigger the video display end to continuously display images corresponding to the image data.

Specifically, when the preset image data is image data, the preset image data is stored in the storage module and is only one frame of image data, so that if the corresponding image is to be continuously displayed, the image data needs to be circularly acquired from the storage module, and after the image data is acquired each time, the image data is transmitted to the video display end, so that the video display end can continuously display the image corresponding to the image data.

Therefore, the mode in the embodiment can enable the video display end to continuously output pictures, enhances man-machine interaction experience, and is simple and reliable in implementation mode.

when the preset image data is preset video data, circularly acquiring a plurality of frames of video data in the preset video data, and sending the acquired frames of video data to a video display end so as to trigger the video display end to continuously display videos corresponding to the frames of video data.

Specifically, when the preset image data is video data, the preset image data is video data composed of multiple-needle image data when stored in the storage module, and at this time, when a picture is displayed on the video display end, the complete video can be selected to be displayed or a part of the fragments in the complete video can be selected to be displayed. Depending on the configuration of the user.

Specifically, if the user configures to circularly play the complete video, the video data corresponding to the complete video needs to be circularly acquired and sent to the video display end, so that the video display end circularly plays the complete video. If the user is configured to circularly play a certain segment in the complete video, the video data corresponding to the segment can be circularly acquired, so that the video display end circularly plays the video corresponding to the segment. The configuration of the user can also be that the complete video is played once at preset time intervals, and the video is frozen in a certain image after being played, correspondingly, the video data are acquired at preset time intervals, and the image data corresponding to the image to be displayed are acquired circularly after the video data are acquired. Of course, the foregoing embodiments are merely specific examples of the present embodiments, and other implementations are possible, which are not limited herein.

In summary, in the manner of this embodiment, not only can the video display end continuously output the picture, but also the video display end can display different pictures according to the configuration of the user, and the configuration manner is flexible, so as to improve the human-computer interaction experience.

As a preferred embodiment, the baseboard management device is configured to monitor an operation state of a host, and the method further includes:

and acquiring working parameters of the host end, and determining whether to trigger the video display end to display alarm information according to the working parameters and a preset parameter threshold value.

Furthermore, in consideration of the alarm condition occurring at the local server main board end in the related art, such as the conditions of over-high CPU temperature and abnormal main board voltage at the host end, abnormal power of PSU (Power supply unit ) and the like, the video display end is not actively controlled to display alarm information, only an alarm log is given, and the user can know the alarm condition when actively viewing the alarm log. That is, the user also needs to actively acquire the alarm information, which may cause the user to miss the alarm information, so that related processing measures cannot be timely taken, and the server motherboard may be damaged.

In order to solve the technical problems, the method and the device for displaying the alarm information in the video display terminal further acquire working parameters of the host terminal, and determine whether to trigger the video display terminal to display the alarm information according to the working parameters and preset parameter thresholds, wherein the preset parameter thresholds are configured in a register in advance, and after the working parameters are acquired, the acquired working parameter values are compared with the preset parameter thresholds in the register to determine whether to send the alarm information.

In the embodiment, the alarm is not performed in an alarm log mode, but the alarm information is directly displayed through the video display end, so that a user can see the alarm information in time, and relevant processing measures are taken according to the displayed alarm information, and the damage of a server main board is avoided.

As a preferred embodiment, the hardware interface of the baseboard management device is connected with the acquisition device, and the method for acquiring the working parameters of the host includes:

the control acquisition device acquires working parameters of the host end acquired by the substrate management device through a hardware interface.

Specifically, the present embodiment is intended to define the manner in which the operating parameters are obtained as follows: the acquisition device is arranged in the substrate management device and is connected with a hardware interface used for acquiring the working parameters in the substrate management device, so that the working parameters can be acquired through the hardware interface. It should be noted that the number of the hardware interfaces in the present application may be, but is not limited to, a plurality of the hardware interfaces, and each hardware interface user obtains different types of working parameters.

Therefore, in the method, the alarm information can be directly displayed through the video display end in a mode that the acquisition device with the hardware structure is connected with the hardware interface, and the alarm mode is obvious.

As a preferred embodiment, if a preset parameter threshold is preset in the acquisition device, determining whether to trigger the video display end to display the alarm information according to the working parameter and the preset parameter threshold includes:

determining whether the working parameter reaches a preset parameter threshold;

when the preset parameter threshold is reached, triggering the video display end to display alarm information.

Specifically, the mode of judging whether to trigger the video display end to display the alarm information is as follows: judging whether the acquired working parameters reach a preset parameter threshold, if so, judging that an alarm is required, and at the moment, triggering a video display end to display alarm information.

As a preferred embodiment, after determining to trigger the video display end to display the alarm information, the method further includes:

and transmitting the alarm data to the video display end to trigger the video display end to display alarm information.

When the alarm information is an alarm image or a video, the alarm information may be, but not limited to, acquired and stored alarm data in advance, and the alarm data is transmitted to the video display end, so as to trigger the video display end to display the corresponding alarm data.

As a preferred embodiment, at least two preset parameter thresholds are preset in the acquisition device, and the values of the preset parameter thresholds are different, when the working parameter reaches the preset parameter threshold, the video display terminal is triggered to display alarm information, including:

when the working parameter reaches any preset parameter threshold, triggering the video display end to display alarm information corresponding to the preset parameter threshold reached by the working parameter.

Specifically, a plurality of preset parameter thresholds can be set in the acquisition device, and the different preset parameter thresholds have different values, so that when the working parameter and the preset parameter threshold are judged, the working parameter can be classified according to the preset parameter threshold reached by the working parameter, and further, the video display end is triggered to display alarm information corresponding to the reached preset parameter threshold. Specifically, if at least a first preset parameter threshold value and a second preset parameter threshold value are set in the acquisition device, and the first preset parameter threshold value is smaller than the second preset parameter threshold value, when the working parameter is smaller than the first preset parameter threshold value, judging that the working parameter is a safety level, and not triggering to display alarm information at the moment; if the working parameter reaches a first preset parameter threshold but does not reach a second preset parameter threshold, judging that the working parameter is a dangerous level of a first degree, and triggering first alarm information corresponding to the first preset parameter threshold at the moment; if the working parameter reaches a second preset parameter threshold, judging that the working parameter is a dangerous grade of a second degree, and triggering second alarm information corresponding to the second preset parameter threshold at the moment.

The mode in the embodiment can carry out different alarms on the working parameters of different grades so as to facilitate the user to distinguish the alarm conditions of the working parameters, thereby facilitating the selection of a proper processing strategy and ensuring the safety of the main board.

As a preferred embodiment, determining whether the operating parameter reaches a preset parameter threshold comprises:

acquiring a judging signal output by the acquisition device, wherein the judging signal comprises comparison results of working parameters and preset parameter thresholds;

and determining whether the working parameter reaches a preset parameter threshold according to the judging signal.

Specifically, the specific manner in which the present embodiment aims to define the comparison of the operating parameter and the preset parameter threshold is: the working parameter and the preset parameter threshold values are compared in the acquisition device, a judging signal containing the comparison results of the working parameter and the preset parameter threshold values is output, whether the working parameter reaches the preset parameter threshold value or not is determined based on the judging signal, and when the preset parameter threshold value is determined to be reached, which preset parameter threshold value is reached is determined according to the judging signal.

For example: after the user/developer configures the preset parameter threshold of the relevant interface, for example, the hardware interface IIC0 obtains a certain key interface voltage of the main board, the standard voltage is 3.3V, the highest upper limit (the second preset parameter threshold) is 5V, the dangerous upper limit (the first preset parameter threshold) is 4.2V, the user sets the relevant register in the acquisition device to be 5V and 4.2V respectively, then compares the obtained value of the IIC0 interface with the value of the register, and if the obtained value exceeds the value of the relevant register, the relevant signal iic0_error is pulled up [1:0]. Such as: IIC0_ERROR [1:0] = 2' b0, indicating that the voltage does not exceed 4.2V; iic0_error [1:0] =2' b1, representing voltages exceeding 4.2V but less than 5V; IIC0_ERROR [1:0] = 2' b2, indicating a voltage exceeding 5V. The same method processes interfaces of the hardware interface IIC 1-ICC_N-1 and the like to obtain IIC 1-ERROR-IIC_N-1-ERROR related signals.

As a preferred embodiment, the alarm information at least comprises background color alarm information and text alarm information.

Specifically, the alarm information may be configured to include a combination of background color alarm information and text alarm information, at this time, the visual impact of the background color alarm information is large, so that the user can find the alarm information in time, and the backgrounds with different colors may be configured to alarm with different degrees, so that the user can select a proper processing strategy according to the degree of the alarm information. In addition, the working condition of the alarm can be described through the text alarm information, so that a user can quickly and accurately position the alarm position according to the text alarm information.

For example, relevant alarm images are stored in a storage module in advance, for example, image 0 is stored for iic0_error [1:0] =2' b1, the image size is 64 x 64, the background color is yellow, the content is that certain interface voltage is higher, and words such as fast processing are processed. For another example, for iic0_error [1:0] =2' b2, image 1 is stored, the image size is 64×64, the background color is red, the content is that some interface voltage is very high, and the words must be processed. That is, if the value of IIC0_ERROR [1:0] is 0, no processing is performed (i.e., no alarm is performed), if the value is 1 or 2, it is determined that an alarm is required, and a relevant memory address is read, which is preconfigured into the hardware, so as to obtain corresponding alarm information according to the memory address. Similarly, the processing manner of the determination signal output by the other hardware interfaces is the same as the above manner, and the disclosure is not repeated here.

As a preferred embodiment, when the types of the working parameters at least include two types, and the working parameters reach a preset parameter threshold, triggering the video display end to display alarm information includes:

when the working parameters reach a preset parameter threshold, determining the type of the working parameters reaching the preset parameter threshold;

and determining corresponding alarm information according to the type of the working parameter reaching the preset parameter threshold and the preset parameter threshold, and triggering the video display end to display the determined alarm information.

Specifically, when the acquisition device is considered to be connected with a plurality of hardware interfaces of the substrate management device and each hardware interface is used for outputting one type of working parameter, if the working parameter reaches a preset parameter threshold, the type of the working parameter needs to be determined, at the moment, alarm information corresponding to the type of the working parameter and corresponding to the reached preset parameter threshold is acquired, so that a video display end is triggered to display the corresponding alarm information, and a user can conveniently determine the type of the alarm according to the alarm information.

It should be noted that the type of the operation parameter may be determined by a hardware interface that acquires the operation parameter, for example, a first hardware interface is configured as an interface that transmits a voltage parameter, a second hardware interface is configured as an interface that transmits a current parameter, or the like.

As a preferred embodiment, after acquiring the alarm data corresponding to the alarm information in the storage address according to the storage address, the method further includes:

transmitting the alarm data to the video display end to trigger the video display end to display the alarm information, comprising:

and transmitting the combined data to a video display end so as to trigger the video display end to display at least alarm information.

Specifically, after the alarm is determined to be needed, the alarm data and the video data transmitted by the host end can be combined to obtain combined data, and the combined mode can completely replace the video data by the alarm data so as to only display the alarm information, or can replace part of the video data by the alarm data so as to display a combined picture of the alarm data and the video data.

As a preferred embodiment, combining the alarm data and the video data transmitted by the host end to obtain combined data includes:

and replacing the pixel value of the preset configuration position of the video data with the pixel value of the alarm data according to the preset configuration position, the video data and the alarm data to obtain the combined data so as to display the synthesized picture of the alarm data and the video data on the video display terminal.

Specifically, in order to realize the function of displaying the alarm information, normal display of the video data sent by the host is not affected as much as possible, the alarm information may be displayed at a preset configuration position of a video picture corresponding to the video data, where the preset configuration position is the configuration information issued by the user, when the video data and the alarm data are combined, the pixel value at the preset configuration position of the video data is replaced by the pixel value of the alarm data according to the preset configuration position, the video data and the alarm data, so as to obtain the combined data, so that a composite picture of the alarm data and the video data is displayed at the video display, the alarm information is displayed at the preset configuration position, and the video information corresponding to the video data is generated at the rest positions.

Such as the user being configured to: and displaying the alarm information at the left upper corner of the original video, calculating the value of an HS/VS signal at the left upper corner according to the current resolution information at a DVI interface of a VGA of a detection video display end, and correspondingly replacing the pixel value of the original video with the pixel value corresponding to the alarm information when the value of the HS/VS signal is the left upper corner information of the original video, so that the relevant coverage of the alarm data to the video data is completed.

As a preferred embodiment, replacing the pixel value at the preset configuration position of the video data with the pixel value of the alarm data according to the preset configuration position, the video data and the alarm data to obtain the combined data, including:

if yes, the pixel value of the video data is replaced by the pixel value of the alarm data, and the combined data is obtained.

In the process of transmitting data to a video display end, when the data needs to be compressed, the process of transmitting the data to a later stage compression unit is divided into two types: one is a mode of a DVI interface, and the other is a BUFFER mode in which video data transmitted from a host side is stored in a storage module and then compressed by a compression unit. The merging of the DVI interface mode is the same as the merging process described above, and will not be described in detail herein, if the merging of the BUFFER mode is required, according to the head address, resolution, and address of the read interface (of AXI (Advanced eXtensible Interface, bus protocol) bus) in the storage module of the video data sent by the configured host end, whether the address of the read interface reaches the position to be merged configured by the user, if so, the video data sent by the host end is covered by the alarm data. And then the combined data is formed and then sent to a compression unit for video compression, and then the combined data is transmitted to a remote video display end, so that a user of the remote video display end can receive alarm information when the user opens the monitoring management interface.

As a preferred embodiment, replacing the pixel value of the video data with the pixel value of the alarm data, and after obtaining the combined data, further includes:

compressing the combined data, transmitting the compressed data to a video display end, and triggering the video display end to decompress the compressed data so as to display a synthesized picture of the alarm information and the video data.

Further, the remote video display receives the combined data in a compressed mode, so that after the compressed data is received, the compressed data is decompressed to display a synthesized picture of the alarm information and the video data. In the data transmission process, the data transmission quantity can be reduced by means of compression and decompression, and the transmission efficiency is further improved.

Fig. 5 is a block diagram of an optimized video function process provided in the present application. During normal operation, the host transmits video data to the VGA, and the first picture processing unit acquires the video data from the VGA and transmits the video data to the first display end to display a video picture. The VGA stores the video data into the storage module, the compression unit reads the video data from the storage module and compresses the video data, then the compressed video data is stored into the storage module and transmitted to the second display end through the EMAC, and the second display end decompresses the data and displays the video picture. When the host end does not transmit video data, the acquisition unit acquires preset image data stored in the storage module in advance, and the acquisition unit transmits the preset image data to the first display end through the first picture processing unit so as to display a picture corresponding to the preset image data (wherein when the working parameters acquired by the acquisition device are abnormal, the acquired preset image data is alarm data, and the information correspondingly displayed is alarm information). When the host end has video data transmission and needs to display alarm information, the second picture processing unit performs merging processing on the alarm data and the original video data according to whether the first address, the resolution and the address of the reading interface in the video data storage module reach the position to be merged or not, if so, the compression unit reads the merged data, compresses the merged data and then writes the merged data into the storage module, and the merged data is sent to the second display end through the EAMC to display a synthesized picture corresponding to the alarm information and the video data.

The VGA stores the video data into the storage module, the compression unit reads the video data from the storage module and compresses the video data, then the compressed video data is stored into the storage module and transmitted to the second display end through the EMAC, and the second display end decompresses the data and displays the video picture.

As a preferred embodiment, before transmitting the data to the video display end, the method further comprises:

performing color space conversion on the data to obtain converted data;

and reading each data from the first-in first-out queue and/or the public storage space according to the storage position of each recorded data, compressing each data, and transmitting the compressed data to the video display end.

Specifically, in the related art, when processing video output, the color space conversion module is firstly performed on original video data output by the VGA to convert the original video data in RGB format into data in YUV format, then the Y, U, V data is buffered (i.e. first in first out queue FIFO) by using storage resources in a chip, and according to the requirement of BLOCK format conversion (such as YUV444/YUV422/YUV420 compression format), 16 y_fifos, 16 u_fifos and 16 v_fifos are required, and meanwhile according to project practice experience, for the condition that the FIFO is full and no loss occurs under the condition that the FIFO is not full (1920×1200) and the FIFO has a depth of 16384 and a width of 8bits can be satisfied. In practice, the FIFO depth actually required is directly from 8192 to 16384, because the FIFO depth can only be power of 2, and therefore, large FIFO resources are wasted. The required on-chip storage space is up to 768KB, which is very unfavorable for the area and cost control of the chip, and simultaneously, the FIFO with large quantity and capacity is a great difficult problem for the time sequence constraint of the chip, the back-end design, the packaging manufacture and the like.

Therefore, in this application, a common storage space (a common RAM (random access memory, random access memory)) is provided, and when data is stored, a part of the data is stored in the FIFO queue, and the other part of the data is stored in the common storage space, and the position of each data storage is recorded, so that the later stage compression unit reads the corresponding data according to the recorded position of each data storage, performs compression processing on the corresponding data, and transmits the compressed data to the video display terminal to display the corresponding data.

As shown in fig. 6, fig. 6 is a block diagram of an optimized video function provided in the present application, in this embodiment, the depths of y_fifo_0, y_fifo_15, u_fifo_0, u_fifo_15, v_fifo_0, v_fifo_15 are set to 8192, and the ram_public (common memory space) is added, where the depth of the RAM may be set to 49152, the RAM is with address information, then y_fifo_0 writes to the 0-1023 addresses of the ram_public after being full, and y_fifo_1 writes to the 1024-2047 addresses … … v_fifo_15 of the ram_public after being full, that is, each FIFO only needs an extra 1024 address space to satisfy the scene of maximum resolution of 1920 by 1200. Meanwhile, the fifo_ctrl_new needs to be modified correspondingly, the logic on the writing side is as described above, and the logic on the reading side is not repeated, so that the FIFO needs to be optimized correspondingly, and the statistics of which data is written into the FIFO is needed, and then the corresponding reading is performed. Thus, in this embodiment, the on-chip memory space required for the video compression function is 48×8192+49152=432 KB, whereas the conventional scheme requires 48×16384=768 KB. Compared with the traditional scheme, the method reduces (768-432)/768=43.75% of on-chip resources, greatly reduces the space of the on-chip resources occupied by the video compression function, greatly saves project cost, reduces chip area and also increases the reliability and stability of the chip. The video_comp_ip in fig. 6 functions the same as the video_comp_ip in fig. 2, and is not described here again.
