[0048] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail in conjunction with the drawings.

[0049] The display module control method provided by the present application can achieve the communication of the combination of display boards and improve the user experience.

[0050] Embodiment 1

[0051] Figure 1 Shows the implementation process schematic diagram of a display module control method provided by an embodiment of the present invention.

[0052] See Figure 1 , the display module control method provided by the embodiment of the present invention may include steps 101 to step 103.

[0053] Step 101: Obtain the positions of each display board in the display module, and the display module includes at least 2 display boards.

[0054] In the embodiment of the present invention, multiple display boards in a certain system can be connected to form a display module for common display and unified control.

[0055] In some embodiments, step 101 includes:

[0056] Obtain the connection relationship between each display board, and the connection relationship includes the relative positions between each display board;

[0057] Taking the main display board as the origin, determine the positions of each display board in the display module based on the connection relationship.

[0058] Based on the position coordinates of each display board, the relative positions of each display board can be determined, providing a basis for communication between each display board.

[0059] Step 102: Based on the positions of each display board, determine the communication paths between the main display board and each display board, and the main display board is any display board in the display module.

[0060] In some embodiments, step 102 includes:

[0061] Based on the positions of each display board, determine the shortest communication paths between the main display board and each display board;

[0062] Select the communication paths between the main display board and each display board from each shortest communication path according to a preset path selection rule.

[0063] In a specific example, the preset path selection rule includes that the sum of each shortest communication path is the shortest.

[0064] In a specific example, the preset path selection rule includes that the length of the overlap between each shortest communication path is the shortest.

[0065] By determining the optimal communication path, the total communication duration can be reduced, avoiding redundancy or waste.

[0066] Step 103: Communicate between the main display board and each display board based on the communication path.

[0067] In some embodiments, Step 103 includes:

[0068] Transfer data through adjacent display boards by means of named communication, and communicate between the main display board and each display board based on the communication path.

[0069] In some embodiments, named communication means that the main display board communicates with a certain target display board, and only sends 0 data to the named target display board, without sending data to the display boards that do not need to communicate currently.

[0070] In some embodiments, the method further includes:

[0071] Obtain the display content of each display board before the display boards are combined into the display module.

[0072] Adjust the position of the display content based on a pre-stored display template and display it on the display module.

[0073] In some embodiments, the display boards before combination respectively display various types of information. For example, the first display board displays multiple data of the first device, the second display board displays multiple data of the second device, and the third display board displays multiple data of the third device. In the combined display module, the first display board displays the first item of data of the three devices, the second display board displays the second item of data of the three devices, and so on.

[0074] Optionally, the display board combination can perform energy-saving display. When a certain condensing unit is not refrigerating or is shut down, the corresponding display board can be turned off to save energy.

[0075] The display module control method provided by the embodiments of the present invention can avoid confusion when multiple devices correspond to multiple display boards, network based on the reserved interfaces of the display boards, and achieve modular control. Thus, multiple units can be controlled through the main display board or some display boards, and functions such as effective adjustment of various parameters, display of various data, and monitoring of fault parameters can be realized. Further, through the connection of the display boards, data synchronization can be achieved. Through the above integrated control, the control frequency of the display board by the user can be effectively reduced, the operation complexity of the display board can be lowered, one-to-many control and data synchronization can be achieved, and the convenience and efficiency of user use can be improved.

[0076] Embodiment 2:

[0077] A specific example is used to further illustrate the display module control method provided by the present invention.

[0078] See Figure 2, in a specific example, this method is applied to a cold storage system, which has multiple condensing units, and each condensing unit is equipped with a display board to display the setting information and various real-time parameters of the corresponding unit, such as temperature data and fault alarm information. When the scale of the cold storage is large and the number of condensing units is large, multiple corresponding display boards will be set on the console of the cold storage for display and interactive control. At this time, the corresponding relationship between the display board and the condensing unit is easy to be confused, and multiple operations are required when setting the unit, resulting in low efficiency.

[0079] See Figure 3 , in the method provided by the embodiment of the present invention, multiple display boards are combined and modularly installed. Specifically, the edge of each display board has power supply and communication contacts for communication and positioning during combination. Each display board can be connected through the contacts, and they are collectively called an integrated display group. The connected display boards can perform data interaction and data synchronization, so there is no need for repeated settings.

[0080] Optionally, each contact is a four-point interface, which are 12V power supply interface, ground interface and two full-duplex communication interfaces respectively. Optionally, 20 contacts are provided on each side of the display board.

[0081] Optionally, the contacts are connected by means of snap and magnetic attraction. The snap is used for precise positioning and provides support for the display board, and the magnetic attraction is used to achieve the attraction between the display boards and control the direction of attraction.

[0082] In a specific example, there are a total of four display boards. After the display boards are combined through the contacts, the positions of each display board are judged according to the contacts connected to each display board.

[0083] For example, the upper side of each display board is marked as A, the right side is marked as B, the lower side is marked as C, and the left side is marked as D. If the BC side contacts of the No. 1 display board are connected, the CD side contacts of the No. 2 display board are connected, the AB side contacts of the No. 3 display board are connected, and the AD contacts of the No. 4 display board are connected, the connection method of the display boards can be determined through the connection of the contacts as Figure 3 .

[0084] For another example, the position of the display board is determined according to the contact communication situation of the display board. When the contacts on a certain side of the display board are connected, it means that this side is connected to other display boards. For example, display board 1 can communicate directly with display boards 2 and 3, so it is determined that display board 1 is directly connected to 2 and 3. Similarly, the arrangement of the display boards is determined according to the communication situation between other display boards. Optionally, the coordinate of any display board is set as the origin, and the arrangement is determined based on the relative positions of each display board and this display board. The display board connected to the right side B of the display board at the origin has the position of (1, 0), and the display board connected to the lower side C of the display board at the origin has the position of (0, -1)

[0085] Identifying the number and positions of display boards can better arrange the display content reasonably on the display group.

[0086] In some embodiments, the combined display boards can form a group control group to achieve group control and perform mesh communication. Each display board can communicate directly with adjacent display boards, reducing communication links. There is no need for a one-to-one hand-in-hand connection between display boards, improving communication efficiency.

[0087] In some embodiments, name calling communication is performed between the combined display boards. Specifically, any one display board is selected as the main display board, and the main display board exchanges data with other display boards. Among them, the display boards adjacent to the main display board can receive the data first and then transmit the name calling data to other adjacent display boards. Coordinate data within the display board combination is pre-stored in each display board to determine the optimal data transmission path. The display board that has already received the name calling data will not receive the name calling transmission data from other display boards to avoid invalid data transmission or data redundancy.

[0088] In a specific example, addresses are set for each display board, and the display board with the smallest address is used as the main display board to synchronously control the temperature adjustment and operating state control of multiple units in the control group. For example, the library temperature is displayed on the main display board, and information such as pressure values, data curves, and fault alarms are displayed on other display boards respectively to improve the utilization rate of the display boards and facilitate user viewing.

[0089] In summary, the display module control method provided by the embodiments of the present invention can achieve modular integrated switching of display boards, realize individual control and group control of cold storage units, improve the efficiency of parameter setting through data synchronization between display boards, display more data content, and improve the utilization rate of display boards and user experience.

[0102] Select the communication path between the main display board and each display board from each shortest communication path according to a preset path selection rule.
