Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and examples.
FIG. 1 is a diagram illustrating an exemplary configuration of a transmitter card for a tiled screen in one embodiment. Fig. 2 is a schematic diagram of the operation of the transmitter card shown in fig. 1. Referring to fig. 1 in conjunction with fig. 2, in one embodiment, a transmitter card 10 for a tiled screen may include a plurality of ports 100, a processor 110 and a logic device 110 coupled to the plurality of ports 100, and a shared storage medium 130 coupled to the processor 110 and the logic device 120. Each of the network ports 100 may be cascaded with a receiving card, the shared storage medium 130 may be a non-transitory computer readable storage medium, and the client 20 connected to the sending card 10 may be an upper computer for implementing a software screen matching function on the mosaic screen 30.
The processor 110 is configured to obtain the loading specification of each network port 100 in response to a screen configuration information display instruction sent by the client 20.
In actual use, only a part of the network ports 100 may carry the receiving card of the spliced screen 30 (in the diagrams of fig. 1 and 2, a part of the network ports 100 are taken as the network ports in use as an example), by obtaining the loading specification of each network port 100, which network ports 100 belong to the network ports in use carried actually can be identified, and the loading specification of each network port 100 (network port in use) of the receiving card in use carried with includes the cascade sequence and the screen attribute of the receiving card carried with the network port 100.
The cascading sequence of the receiving cards may indicate which receiving cards are carried by each portal 100 and the cascading sequence of the receiving cards at the portal, and the screen attribute (or may also be referred to as screen type) of the receiving card may indicate parameters such as the display size and resolution of the display screen connected to the receiving card.
In addition, in actual use, the processor 110 may detect the loading specification at each portal 100 in response to the screen configuration information display instruction sent by the client 20, for example, the processor 110 may detect a receiving card at the portal 100, indicate that the portal 100 is not an active portal if a receiving card is not detected at a certain portal 100, and count the cascade order of the detected receiving cards and obtain the screen attribute supported by the detected receiving card from the feedback information of the receiving card if a receiving card is detected at a certain portal 100. The loading specification of each portal 100 detected by the processor 110 can be reported to the client 20.
Since the transmitting card 10 may have the capability of detecting the loading specification of each portal 100, the processor 110 may also detect the loading specification at each portal 100 and report the loading specification to the client 20 before the client 20 sends the screen configuration information display instruction, in this case, the screen configuration information display instruction sent by the client 20 may carry the loading specification of each portal 100, and accordingly, the processor 110 may also obtain the loading specification of each portal 100 from the screen configuration information display instruction without repeated detection.
For example, the processor 110 may obtain a port serial number of each port and a character pattern of a cascade serial number of each receiving card in a cascade sequence of the receiving cards carried by the port; according to the layout pattern that the serial number of the network port and the cascade serial number of the receiving card are arranged side by side and are spaced by separators, the character patterns of the serial number of the network port and the cascade serial number of the receiving card are rendered in the bottom plate image of Bitmap (BMP) format matching with the screen attribute, and the screen configuration information single-screen image 210 of Bitmap format is obtained.
In actual use, the shared storage medium 130 may store a character library, and the processor 110 may query and call a character pattern of the port serial number and the receiving card cascade serial number from the character library.
In addition to presenting the serial number of the network port and the serial number of the cascade of the receiving cards, other prompt information, the carrying capacity of the network port and/or the color information for distinguishing different network ports by colors can be added to the single screen image 210 of the screen configuration information.
For the requirement of the loadable capability of the additional net port in the single-screen image 210 of the screen configuration information, the processor 110 may further estimate the loadable capability of each net port according to the obtained loaded specification. The loadable capability may be expressed as a maximum number of receivable cards or a maximum number of boxes that can be loaded.
For example, the determination process of the maximum number of loadable receiving cards can be expressed as the following expression (1):
wherein, N card_max B represents the bandwidth of the network port, namely the data volume (for example 125 Mm) which can be transmitted by the network port in unit time, W represents the width of the display size defined by the screen attribute of the receiving card, H represents the height of the display size defined by the screen attribute of the receiving card, a, B and c are all the preset display sizesThe set conversion constant (for example, a may be 3, b may be 70, and c may be 60).
For another example, the determination process of the maximum number of loadable boxes can be expressed as the following expression (2):
wherein N is box_max Representing the maximum number of boxes that can be loaded, N card The number of the receiving cards actually contained in a single box is represented, B represents the bandwidth of the network port, that is, the data volume (for example, 125 megabits) which can be transmitted by the network port in unit time, W represents the width of the display size defined by the screen attribute of the receiving card, H represents the height of the display size defined by the screen attribute of the receiving card, and a, B, and c are all preset conversion constants (for example, a may be 3, B may be 70, and c may be 60).
When there is more than one receiving card loaded by the portal 100, the processor 110 may obtain a character pattern of the loadable capability of the portal 100 (for example, from a character library stored in the shared storage medium 130), and render the obtained character pattern of the loadable capability in a single-screen image of the screen configuration information of the first receiving card cascaded by the portal 100.
For the requirement of distinguishing color information of different ports by adding colors in the screen configuration information single-screen image 210, the processor 110 may further obtain a corresponding relationship between the screen ports and the interface presentation colors set in the client 20, in order to keep visual consistency between the presentation colors of the screen configuration information single-screen image 210 and the interface presentation colors of the client 20, and according to the obtained corresponding relationship, the processor 110 may convert the screen configuration information single-screen image 210 in the BMP format into the RGB format, where the color converted by the screen configuration information single-screen image 210 of the receiving card of each screen port 100 is the interface presentation color corresponding to the screen port 100 at the client 20.
The processor 100 is further configured to merge the created screen matching information single-screen images 210 into a screen matching information integrated image 220, store the screen matching information integrated image 220 in the shared storage medium 130, and notify the logic device 120 of the acquisition (for example, report an interrupt to the logic device 120).
If color distinction is not introduced, the spliced screen matching information single-screen image 210 can still be in the BMP format, and if color distinction is introduced, the spliced screen matching information single-screen image 210 can be in the RGB format. And, the processor 110 may merge the created screen matching information single-screen images 210 into the screen matching information integrated image 220 according to the sorting rule of the network port number and the cascade number. For example, the created screen matching information single-screen image 210 is merged into the screen matching information integrated image 220 in the order of progression of the portal number and the cascade number.
The logic device 120 is configured to, in response to a notification from the processor 110 (for example, in response to an interrupt reported by the processor 110), acquire the screen configuration information integration image 220 from the shared storage medium 130; the screen matching information single-screen image 210 of the receiving card carried by each network port 100 (the network port in use) is sequentially intercepted from the acquired screen matching information integrated image 220 and is transmitted through the network port 100.
The logic device 120 may sequentially intercept the screen configuration information single-screen image 210 from the screen configuration information integrated image 220 by using the serial number of the network port and the cascade serial number as an ordering rule (the same as the ordering rule used when the processor 100 is spliced), so that the logic device 120 may position the corresponding network port 100 according to the same order of intercepting the screen configuration information single-screen image 210 to transmit the screen configuration information single-screen image 210, so as to ensure that the screen configuration information single-screen image 210 is positioned and presented on the spliced screen 300.
Based on the above embodiment, the processor 110 of the sending card 10 may generate in batch the screen matching information single-screen images 210 of the receiving cards cascaded by the respective portals 100 and combine them into the screen matching information integrated image 220, the screen matching information integrated image 220 may be transferred from the processor 110 to the logic device 120 through the shared storage medium 130, and the logic device 120 may sequentially intercept the screen matching information single-screen image 210 of the receiving card carried by each portal from the screen matching information integrated image 220 and transmit through the portal 10, thereby implementing the screen matching information single-screen image 210 presented on the display screen connected to each receiving card of the combined screen 30 to assist the screen matching operation of the combined screen 30 performed at the client 20.
Moreover, the imaging processing task of the screen matching information is concentrated on the processor 110 of the sending card 10, so that on one hand, the coupling degree between the processor 110 and the logic device 120 and the coupling degree between the sending card 10 and the receiving card can be reduced, and on the other hand, the burden on the logic device 120 and the receiving card of the sending card 10 caused by the screen matching information presentation can be reduced.
In addition, the above embodiment may support the processor 110 of the sending card 10 to set the portal number and the cascade number in a side-by-side arrangement in the presentation content of the single screen image 210 of the screen matching information, and in a simplified form of separating by separators, the screen matching information may be presented more concisely and intuitively. The above embodiment may also support that the processor 110 of the transmitting card 10 adds the loadable capability determined based on the loaded specification to the presentation content of the single-screen image 210 of the screen configuration information, so as to reduce the occurrence probability of the portal overload caused by the manual calculation error or the connection operation error in a visual reminding manner. The above embodiment may also support that the processor 110 of the sending card 10 sets the presentation content of the screen matching information single-screen image 210 to be consistent with the interface presentation colors corresponding to different portals in the client 20, and may generate a visual effect of differentiated presentation of the screen matching information single-screen image 210 by the portals, which is helpful to improve the visual identification.
In addition, after the screen matching operation of the assistant client 20 is completed in combination with the above effects, the client 20 may send a screen matching connection disconnection instruction. Accordingly, the processor 110 may be further configured to release the storage space occupied by the screen matching information integration image 220 in the shared storage medium in response to the screen matching connection disconnection instruction of the client 20, so as to improve the hardware resource utilization rate of the sending card 10.
