Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
It should be noted that, if directional indications (such as up, down, left, right, front, and back … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative positional relationship between the components, the movement situation, and the like in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indications are changed accordingly.
The general steps of debugging the LED (light emitting diode) display screen at present are that firstly, an LED display module or an LED display box body is debugged normally, then, a large screen is assembled, and the whole large screen is subjected to image splicing. In the process of assembling the LED large screen, the connection mode of the receiving card is not fixed, and no uniform standard exists. The existing receiving card connection mode is a vertical connection mode (shown in figure 2), a transverse connection mode (shown in figure 3) and a broken line connection mode (shown in figure 4), and due to the fact that the existing receiving card connection modes are various, the receiving card wiring connection mode of the LED large screen is often required to be clarified for a long time in the image debugging and splicing stage after the LED screen is assembled, then modules or boxes are spliced one by one according to the connection mode, time is consumed in the installation, debugging and large screen using processes, labor cost is increased invisibly, and efficiency is low.
In view of the above-mentioned drawbacks of the prior art, the present invention provides a method for determining a receiving card connection topology by obtaining level variation information of a direction indicating device located on a receiving card. And then determining the cascade direction information of the receiving card according to the level change information of the direction indicating device. And finally, acquiring the address coding data of the receiving card, and generating receiving card connection topology image data according to the cascading direction information and the address coding data. According to the invention, the connection structure between the receiving cards does not need to be judged manually, so that the problem that the wiring connection mode of the receiving cards of the LED large screen needs to be judged by a large amount of manpower in the prior art can be effectively solved.
As shown in fig. 1, this embodiment provides that the method includes the following steps:
and step S100, acquiring the level change information of the direction indicating device on the receiving card.
Specifically, as shown in fig. 5, there is no component on the existing receiving card that can indicate the direction. In this embodiment, in order to automatically determine the connection structure between the receiving cards, a direction indicating device is required to be arranged on each receiving card in advance, the direction indicating device can indicate a plurality of directions, when the direction indicating device indicates one of the plurality of directions, the level data of the direction indicating device before and after the indication changes, for example, the level of the direction indicating device before the indication of the direction is low, and the level of the direction indicating device after the indication of the direction is high, so as to generate corresponding level change information.
In one implementation, as shown in fig. 6, the direction indicating device is a jump hat device, and the step S100 is specifically a step of:
s101, obtaining relative position information of the receiving card, and determining a target connecting column in a plurality of secondary connecting columns of the cap jumping device according to the relative position information of the receiving card;
step S102, obtaining level data of the target connecting column to obtain first level data;
step S103, connecting the main connecting column of the cap jumping device with the target connecting column, and then acquiring level data of the target connecting column again to obtain second level data;
and step S104, generating level change information of the cap jumping device according to the first level data and the second level data.
In brief, the jump cap device is a device for realizing different system functions by adopting a simple jump connection mode, and in the embodiment, the jump cap device is used as a direction indicating device, and the cascade direction indicated by the receiving card is determined to be in which direction by judging which binding post the jump cap device jumps to. Specifically, the present embodiment first obtains the relative position information between the receiving cards, and determines the direction information that should be indicated by the cap-jumping device on each receiving card according to the relative position information between the receiving cards. As shown in fig. 7, the cap-jumping device is composed of a main connection column, a plurality of auxiliary connection columns and a jumping cap, the main connection column is connected with a power supply of a receiving card to provide high level, and other auxiliary connection columns are connected with the control chip. When the direction information which should be indicated by the cap jumping device is determined, the auxiliary connecting column in the direction is used as a target connecting column, and the target connecting column is connected with the main connecting column through the cap jumping. After connection, the level of the target connecting column can be increased, and when the control chip detects the numerical value change of the levels of the target connecting column before and after connection, corresponding level change information can be generated. In an implementation manner, in order to more intuitively recognize the cascading direction of each receiving card, in this embodiment, an indicator lamp may be respectively disposed beside each of the sub-connecting columns, when one of the sub-connecting columns is connected to the main connecting column, the indicator lamp corresponding to the sub-connecting column connected to the main connecting column may be turned on, and according to the turned-on indicator lamp on each receiving card, the cascading direction of each receiving card may be intuitively recognized.
In another implementation manner, as shown in fig. 8, the direction indicating device may further adopt a dial switch device, and the step S100 specifically includes the following steps:
s105, obtaining the relative position information of the receiving card, and determining a target dialing bit in a plurality of dialing bits according to the relative position information of the receiving card;
step S106, obtaining level data of the target shift bit to obtain third level data;
step S107, after the target code shifting bit is opened, obtaining the level data of the target code shifting bit again to obtain fourth level data;
and S108, generating level change information of the dial switch device according to the third level data and the fourth level data.
Specifically, the dial switch is a switch adopting binary coding of 0/1, and the present embodiment adopts the dial switch device as the direction indicating device, and determines which direction the cascade direction indicated by the receiving card is in by judging which dial bit in the dial switch device is in the on state. Specifically, after the relative position relationship between the receiving cards is acquired, the direction information which should be indicated by the dial switch device on each receiving card is determined according to the relative position information between the receiving cards. The dial switch device is composed of a plurality of dial bits, the state of all the dial bits is closed state at the beginning, when the direction information which should be indicated by the dial switch device on the receiving card is determined, the dial bit indicating the direction is used as the target dial bit, and the target dial bit is opened. Because all the shift bits all are connected with control chip, after the target shift bit was opened, the level numerical value of the pin that this target shift bit and control chip are connected can rise, and after control chip detected this level change, will generate corresponding level change information. For example, it is assumed that the toggle switch device has four paths of toggle bits respectively used for indicating four directions, i.e., up, down, left, and right, and the four toggle bits are all connected to the control chip through the pins. If the current receiving card needs to take the upper direction as the self cascade direction, the dialing bit indicating the upper direction is opened, and after the dialing bit is opened, the level state of a pin connected with the control chip can be changed, so that level change information is generated. In an implementation manner, in order to more intuitively recognize the cascade direction of each receiving card, in this embodiment, an indicator lamp may be further disposed beside each of the dialing positions, when one of the dialing positions is turned on, the indicator lamp corresponding to the turned-on dialing position is turned on, and according to the turned-on indicator lamps on each receiving card, the cascade direction of each receiving card can be intuitively recognized.
As shown in fig. 1, the method further comprises the steps of:
and step S200, determining the cascade direction information of the receiving card according to the level change information of the direction indicating device.
Specifically, after the control chip detects the level change information of the direction indicating device, the control chip analyzes the level change information to determine the direction indicated by the direction indicating device, where the direction is the cascade direction of the receiving card where the direction indicating device is located.
In an implementation manner, when the direction indicating device is a cap jumping device, the step S200 specifically includes:
step S201, acquiring direction information corresponding to the target connecting column according to the level change information of the cap jumping device;
and step S202, taking the direction information corresponding to the target connecting column as the cascading direction information of the receiving card.
After the control chip acquires the level change information of the cap jumping device, an auxiliary connecting column (namely a target connecting column) connected with the main connecting column is determined according to the level change information, direction information indicated by the auxiliary connecting column is acquired, and the direction information is used as the cascading direction of a receiving card where the cap jumping device is located. For example, as shown in fig. 9, 4 receiving cards are placed in a 2 × 2 manner, in fig. 9, the receiving card at the lower left corner is set as the 1 st receiving card connected to the sending card, the cascaded 2 nd receiving card is above the 1 st receiving card, the cascaded 3 rd receiving card is at the left side of the 2 nd receiving card, and the cascaded 4 th receiving card is below the 3 rd receiving card. Because 2 the card is on 1 st card, so the jumper cap of 1 st receiving card links the spliced pole that leads to, shows 2 nd card at the upside position of 1 st card, 3 rd card is on the right side of 2 nd card, so the jumper cap of 2 nd card links the spliced pole that leads to right, shows 3 rd card at the right side position of 2 nd card, 4 th card is under 3 rd card, so the jumper cap of 3 rd card links the spliced pole that leads to down, shows 4 th card at the downside position of 3 rd card. Since there is no cascaded receiving card behind the last 1 receiving card, there is no need to determine the cascading direction of the last 1 card. As shown in fig. 11, after the cascade direction of the 1 st, 2 nd, and 3 rd cards is determined, the connection structure between the 1 st, 2 nd, 3 th, and 4 th cards can be obtained.
In an implementation manner, when the direction indicating device is a dial switch device, the step S200 specifically includes:
step S203, acquiring direction information corresponding to the target dial bit according to the level change information of the dial switch device;
and step S204, taking the direction information corresponding to the target dialing bit as the cascade direction information of the receiving card.
After the control chip acquires the level change information of the dial switch device, the control chip determines the opened dialing bit (namely the target dialing bit) according to the level change information, acquires the direction information indicated by the opened dialing bit, and takes the direction information as the cascade direction of the receiving card where the dial switch device is located. For example, fig. 10 illustrates the cascade direction of 4 receiving cards in the manner of a dial switch. The 4 receiving cards are placed in a 2x2 manner, in fig. 10, the receiving card at the lower left corner is set as the 1 st receiving card connected with the sending card, the cascaded 2 nd receiving card is above the 1 st receiving card, the cascaded 3 rd receiving card is at the left side of the 2 nd receiving card, and the cascaded 4 th receiving card is below the 3 rd receiving card. Each receiving card is provided with 4-bit dialing bits, and the dialing bits 1, 2, 3 and 4 respectively correspond to 4 directions of indicating the upper right, the lower right and the left. In fig. 10, since the 2 nd card is on the 1 st card, the shift bit 1 of the 1 st receiving card is set to the open state, which indicates that the 2 nd card is on the upper side of the 1 st card, and the 3 rd card is on the right side of the 2 nd card, so the shift bit 2 of the 2 nd card is set to the open state, which indicates that the 3 rd card is on the right side of the 2 nd card, and the 4 th card is under the 3 rd card, which indicates that the shift bit 3 of the 3 rd card is set to the open state, which indicates that the 4 th card is on the lower side of the 3 rd card. Since there is no cascaded receiving card behind the last 1 receiving card, there is no need to determine the cascading direction of the last 1 card. As shown in fig. 11, after the cascade direction of the 1 st, 2 nd, and 3 rd cards is determined, the connection structure between the 1 st, 2 nd, 3 rd, and 4 th cards can be obtained.
As shown in fig. 1, the method further comprises the steps of:
step S300, acquiring the address coding data of the receiving card, and generating receiving card connection topology image data according to the cascading direction information and the address coding data.
Specifically, in this embodiment, after the cascade direction of each receiving card is obtained, the address coding data of each receiving card needs to be obtained. Since the address code data of each receiving card is unique, the address code data can be used as the identity of each receiving card. In addition, the address encoding data can also be used to reflect the location of the respective receiving card in the LED display screen. After the positions and the cascading directions of all the receiving cards are determined, the physical layout of all the receiving cards forming the LED display screen can be determined, and then a receiving card connection topological image is obtained.
In one implementation, the step S300 specifically includes the following steps:
s301, acquiring coordinate data corresponding to the receiving card; the coordinate data is used for reflecting the position information of the receiving card in the complete display screen;
step S302, carrying out address coding on the receiving card according to the coordinate data to obtain address coding data of the receiving card;
step S303, generating receiving card connection topology image data according to the cascade direction information and the address coding data.
Specifically, since the coordinate data may be used to reflect the position information of each receiving card in the complete display screen, the present embodiment may use the coordinate data to perform address coding on each receiving card. For example, as shown in fig. 2, in this embodiment, the receiving card connected to the sending card 0 is used as the first receiving card, the coordinate data of the first receiving card is set to (0, 0), and the coordinate data of the receiving card located above the first receiving card is set to (0, 1), that is, the ordinate +1 in the coordinate data of the first receiving card, so that the coordinate data of the receiving card located above the first receiving card can be obtained. Similarly, the coordinate data (1, 0) of the receiving card positioned at the right side of the first receiving card can be obtained by using the abscissa +1 in the coordinate data of the first receiving card, and the coordinate data of all the receiving cards can be calculated according to the method. And then, respectively carrying out address coding on each receiving card according to the coordinate data of each receiving card to obtain the address code of each receiving card. For example, if the coordinate data of the first receiving card is (0, 0), the corresponding address code is 00; if the coordinate data of the receiving card above the first receiving card is (0, 1), the corresponding address code is 01; and if the coordinate data of the receiving card positioned at the right side of the first receiving card is (1, 0), the corresponding address code is 10. After the control system software acquires the cascade direction and the address coding information of each receiving card, the relative direction of each receiving card and the next corresponding receiving card is judged according to the cascade direction of each receiving card, the position of each receiving card in the LED display screen is judged according to the address coding information of each receiving card, the connection structure among all the receiving cards is further determined, and a receiving card connection topological graph is automatically generated.
In one implementation, the method further comprises: and acquiring height information and width information corresponding to the receiving card, and determining size data of the intercepted image. And then determining the position data of the intercepted image according to the receiving card connection topology image data. And finally, acquiring video image data, and intercepting the video image data according to the size data and the position data to obtain display image data corresponding to the receiving card.
Specifically, the present embodiment determines the connection structure between the receiving cards, mainly for determining the display image data corresponding to each receiving card. As shown in fig. 2, a complete LED display screen is composed of a plurality of display modules, each of which is configured with a receiving card. The function of the receiving card is to receive a local image of a certain frame in the video image, and then to send the local image to the corresponding display module to be displayed. Because each display module group displays a local area image in a frame of video image, when the images displayed by all the display module groups are spliced, a complete frame of video image can be displayed, namely, the automatic screen connection of the LED large screen is completed. In order to accurately determine which area of the video image the respective receiving cards should capture the image data, the present embodiment needs to determine the size data of the captured image, that is, the image data of how large area of the video image should be captured, according to the height information and the width information corresponding to each receiving card. And then determining the position data of the intercepted image according to the receiving card connection topological image data, namely, image data of which area in the video image should be intercepted, finally intercepting the video image data according to the obtained size data and the position data, so that display image data corresponding to each receiving card can be obtained, and finally, automatic screen connection of the LED display screen is realized.
