In some application scenarios, multiple display devices need to be integrated together to form a display cluster. Referring to fig. 2, an example of a display cluster is shown. The display cluster 20 comprises 4 display devices 200 and is arranged in a 2 x 2 matrix. That is, 2 display devices are arranged per row (horizontal direction) and 2 display devices are arranged per column (vertical direction).

The display cluster is centrally controlled by a centralized control terminal. Fig. 3 is a schematic diagram of networking a centralized control terminal and a display cluster. In the schematic diagram, the centralized control terminal is connected with the display cluster through a serial port, and display devices (display device 1-display device 4) in the display cluster are connected in series through the serial port. Wherein, the serial port can be an RS485 port.

The centralized control terminal sends a control instruction through a serial port connected with the display cluster, the control instruction comprises a machine number of a display device to be controlled by the centralized control terminal, and the machine number uniquely identifies the display device, namely, each display device has a unique machine number, so that point-to-point control between the centralized control terminal and the display device is realized.

However, the display device usually has only a default machine number at the time of factory shipment, for example, the default machine number is 1. For this reason, each display device needs to be assigned a unique corresponding machine number before control.

In one embodiment, the machine numbers of the display devices in the display cluster can be set one by one through the remote controller. Taking the setting example of one of the display devices, the user may cause the display device to display the GUI shown in fig. 4A on the display in response to the key operation by pressing a setting key on the remote controller.

The GUI includes menu content 41 and a selector 43 for indicating selection of a menu item within the menu content. The user can move the position of the selector 43 in the menu content by operating the remote control to select a different menu item.

The menu content 41 may include menu items such as machine number, horizontal scale, vertical scale, and position. Wherein the machine number is used for uniquely identifying the display device; the horizontal proportion is used for identifying the number of display devices in the display cluster in the horizontal direction; the vertical scale is used for identifying the number of display devices in the vertical direction in the display cluster; the location is used to identify the physical location of the display device in the display cluster.

Taking the top left display device 1 in fig. 2 as an example, when the user presses a set button on the remote controller to make the display device display the GUI shown in fig. 4A, the user can press up and down direction keys on the remote controller to control the selector 43 to select the machine number item. The display device may modify the value of the machine number item in response to a user input adjusting the value of the machine number item. Here, the user assigns a machine number 1 to the 1 st display device in the upper left corner, and thus, the default machine number may not be modified.

The user continues to press the down direction key on the remote controller and controls the selector 43 to select the horizontal scale item. Since the display cluster shown in fig. 2 includes 2 display devices in the horizontal direction, the user needs to operate the remote controller to modify the numerical value of the horizontal scale item in the menu content 41. The display device modifies the value of the horizontal scale item from 1 to 2 in response to a user input adjusting the value of the horizontal scale item.

The user continues to press the down direction key on the remote control and controls the selector 43 to select the vertical scale item. Since the display cluster shown in fig. 2 includes 2 display devices in the vertical direction, the user needs to operate the remote controller to modify the numerical value of the vertical scale item in the menu content 41. The display device modifies the value of the vertical scale item from 1 to 2 in response to a user input adjusting the value of the vertical scale item.

The user continues to press the down direction key on the remote controller and controls the selector 43 to select the position item. The display cluster shown in fig. 2 determines the physical location of the display device in the order from top to bottom and from left to right, and identifies the physical location of the display device by a numerical value. For example, the physical location of the top left corner display device may be identified as 1; the physical location of the top right display device may be identified as 2; the physical location of the lower left corner display device may be identified as 3; the physical location of the lower right hand corner display device may be identified as 4. Since the setting is currently made for the upper left display device, the numerical value of the position item in the menu content 41 is already 1, and therefore, no modification is required.

After the setting of the above-described menu items is completed, the display device displays the GUI shown in fig. 4B. The user continues to operate the remote control and the control selector 43 selects the determined item, and then presses the determined key on the remote control to cause the display device to validate the values of the various menu items in the menu content 41 in response to the user input and to exit the GUI display.

The user needs to perform the above setting process for each display device in fig. 2, and the differences only exist in different set machine numbers and different positions of the display devices, which are not described herein again.

As can be seen from the above-described setting process, since the display apparatus is set using the remote controller, the display apparatus is required to have an infrared receiving device installed, which undoubtedly increases the cost of the display apparatus. And if the display device mounting position is higher, it is very inconvenient to use the remote controller setting, leads to the whole setting efficiency of the display cluster to be lower.

In order to solve the problems, the application provides a machine number setting method. Referring to fig. 5, a flowchart of a method for setting a machine number according to an embodiment of the present disclosure is shown.

As shown in fig. 5, the process may include the following steps:

and step S51, the centralized control terminal sends a broadcast instruction to the display cluster through the serial port, and the broadcast instruction is used for indicating the display equipment to display the machine identification code.

Here, it should be noted that the centralized control terminal is generally an electronic device, such as a computer, including a display and a user input device. The user input device may be a keyboard, a mouse, a touch screen, or the like.

The centralized control terminal may display the number assignment interface 61 shown in fig. 6 on the display. In this step, the user can select the item of the display number through the user input device of the centralized control terminal, and trigger the centralized control terminal to send a broadcast instruction for instructing the display device to display the machine identification code and the machine number.

Referring to fig. 7, a schematic diagram of the structure of the broadcast command is shown. The broadcast instruction includes a start code, a length field, a command code, a machine number field, a display field, a check code, and an end code.

Wherein the start code is used to identify the start of the instruction; the length field is used for identifying the length of the instruction; the command codes are used for identifying different instructions; the machine number is used for identifying the display equipment for receiving the instruction; the display field is used for indicating whether the display device displays the content specified by the current instruction; the check code is used for checking whether the received instruction is correct or not by the display equipment; the end code is used to identify the end of the current instruction.

For example, in fig. 7, command codes "0 xC1,0x19,0x00,0x 00" are used to instruct the display device to operate the machine identification code; the machine number "0 x 00" is used to indicate that all display devices in the display cluster receive the current instruction, in other words, the machine number "0 x 00" indicates that the current instruction is a broadcast instruction; the display field "0 x 01" indicates that the operation that the display device needs to perform on the machine identification code is to display the machine identification code on the display.

In step S52, the display device displays the own machine identification code and the current machine number.

And each display device in the display cluster can receive the instruction sent by the centralized control terminal through the step S51 through the serial port, and acquire the machine number included in the instruction.

The display device determines that the received instruction is a broadcast instruction, which itself needs to be executed, based on the machine number (0x00) included in the instruction.

The display apparatus acquires a command code (0xC1,0x19,0x00,0x00) included in the broadcast command, and determines that an operation is required for the machine identification code based on the command code. The display device further acquires a display field included in the broadcast instruction, and determines that the operation to be performed on the machine identification code is display according to the value (0x01) of the display field. Accordingly, the display device displays the interface 81 shown in fig. 8 on the display. The interface 81 includes a machine identification code (e.g., b1b43) and a machine number (e.g., 1) of the display device.

The machine identification code may be obtained based on a Media Access Control (MAC) address of the display device, for example, the last 5 bits of the MAC address are selected as the machine identification code. The MAC address of each display device is unique, and the machine identification code obtained based on the MAC address is also unique.

Note that, before the device number is not assigned, the device number displayed by the display device is usually a default number at the time of factory shipment, for example, 1.

By executing the step, each display device in the display cluster displays the respective machine identification code on the display.

In step S53, the centralized control terminal receives the machine identification code of the display device and the machine number assigned to the display device, which are input by the user.

The user can obtain the machine identification codes of the display devices through display on the display devices. Then, the machine identification code of the display device and the machine number to be assigned to the display device are input on the number assignment interface 61 of the centralized control terminal using the user input means of the centralized control terminal.

Taking the display cluster shown in fig. 2 as an example, first, the specification of the display cluster, that is, the horizontal proportion (the number of display devices included in each row) and the vertical proportion (the number of display devices included in each column) of the display cluster are configured in the number assignment interface 61 shown in fig. 6. For example, according to the display cluster shown in fig. 2, the number of display devices included in each row in fig. 6 is configured to be 2, and the number of display devices included in each column is configured to be 2, and then the set button is clicked. The centralized control terminal displays a setting area 62 corresponding to each display device in the number assignment interface 61 in response to the user setting.

The setting area 62 includes position information of the display device in the display cluster, which is represented by a numerical value in the lower left corner of the setting area 62. For example, a value of 1 indicates that the corresponding display device is the 1 st display device in the upper left corner of the display cluster; a value of 2 indicates a 2 nd display device horizontally adjacent to the 1 st display device, and so on.

The setting area 62 further includes two input boxes located at the upper right corner of the area, which are used to input the machine identification code of the display device and the machine number assigned to the display device, respectively.

Taking the example that the 1 st display device at the upper left corner in fig. 2 displays the machine identification code b1b43 shown in fig. 8, the user can operate the corresponding setting area 62 of the display device in the number assignment interface 61, that is, the setting area 62 with the position value of 1, through the user input device of the centralized control terminal, and sequentially input the machine identification code b1b43 and the machine number (for example, the machine number of 5) assigned to the display device into two input boxes of the setting area 62. After entry, the number assignment interface 61 is shown in FIG. 9.

And step S54, the centralized control terminal sends a broadcast instruction to the display cluster through the serial port, wherein the broadcast instruction comprises the machine identification code and the machine number input by the user.

After the user inputs the machine id and the machine number in step S54, the user can click the OK button on the lower right corner of the setting area 62. And the centralized control terminal responds to the user input and sends a broadcast instruction to the display cluster, wherein the broadcast instruction comprises the machine identification code and the machine number input by the user.

Referring to fig. 10, a schematic diagram of the structure of the broadcast command is shown. Wherein the command code "0 xC1,0x19,0x01,0x 00" is used to indicate that the display device updates the machine number; the machine number 1 "0 x 00" is used to identify the current instruction as a broadcast instruction; the machine identification code "0 x0B,0x01,0x0B,0x04,0x 03" is the machine identification code of the display device to be set; the horizontal scale "0 x 02" indicates that the display cluster to which the display device belongs includes 2 display devices in the horizontal direction; the vertical scale "0 x 02" indicates that the display cluster to which the display device belongs includes 2 display devices in the vertical direction; the machine number 2 "0 x 05" is the machine number assigned by the user to the display device; location "0 x 01" is used to identify the physical location of the display device in the display cluster.

And step S55, the display device receives the broadcast instruction sent by the centralized control terminal, and if the machine identification code included in the broadcast instruction is the same as the own machine identification code, the own machine number is updated to be the machine number included in the broadcast instruction.

The display device receives an instruction sent by the centralized control terminal through a serial port, and determines the instruction to be a broadcast instruction based on the machine number 1(0x00) included in the instruction. All display devices need to execute the broadcast instructions.

To this end, the display device acquires a command code (0xC1,0x19,0x01,0x00) included in the broadcast command, and determines the command for setting the machine number of the display device according to the command code.

The display device further acquires the machine id (0x0B,0x01,0x0B,0x04,0x03) included in the broadcast command, and determines whether the machine id is the same as the own machine id.

If the instruction is not the same as the instruction sent to the equipment by the centralized control terminal, the instruction is discarded.

If the instruction is the instruction issued by the centralized control terminal aiming at the equipment, the horizontal proportion, the vertical proportion, the machine number 2 and the position information included in the instruction are continuously acquired, and the machine number of the centralized control terminal is updated to the machine number 2 included in the broadcast instruction, so that the machine number setting of the current display equipment is completed.

By repeatedly executing the steps S53-S55, the application sets different machine numbers for each display device in the display cluster.

The flow shown in fig. 5 is completed.

As can be seen from the flow shown in FIG. 5, the serial port connection between the centralized control terminal and the display cluster can be directly utilized, and the instruction for setting the machine number is issued to the display equipment in the display cluster, so that the infrared receiving device does not need to be installed on the display equipment, the equipment cost is saved, the setting mode is not limited by the installation position, and the setting efficiency can be effectively improved.
