Description

Technical Field

[0001] This application relates to the field of LED display technology, and in particular to an automatic positioning device for LED display cabinets. Background Technology

[0002] Currently, LED displays are generally composed of multiple LED cabinets spliced ​​together. Each LED cabinet is equipped with a receiver card, and upon power-on, the receiver cards can display images on the LED cabinets. However, when many LED cabinets are spliced ​​together, the LED display control system must be able to display a unified image or video from all the LED cabinets. Each LED cabinet is equipped with a receiver card, and these receiver cards are cascaded to a transmitting card, which in turn connects to a host computer such as a PC.

[0003] There are two existing methods for positioning LED cabinets: (1) Configuring the display position of the receiving card in each LED cabinet through host computer software or the human-machine interface of the controller to achieve the requirement of displaying a complete image by splicing all the receiving cards together; (2) Obtaining the display start X and Y coordinates of each receiving card and the width and height of each receiving card, and fixing these parameters into the receiving card. Powering on the receiving card, the information stored in the receiving card is read to complete the splicing of all the cabinets into a complete image. However, the above methods have a major drawback: the physical position of each LED cabinet needs to be recorded. During on-site installation, the installation must be carried out exactly according to the physical position of each LED cabinet. It is not possible to place any cabinet in any position, making it very inflexible. Summary of the Invention

[0004] Therefore, it is necessary to provide an automatic LED display cabinet positioning device to address the above-mentioned technical problems. This device can detect the LED cabinet ID through hardware connection, and flexibly replace the LED cabinet by placing any cabinet in any position, thereby improving maintenance and work efficiency.

[0005] In a first aspect, the present invention provides an automatic positioning device for an LED display cabinet, comprising a DIP switch module, a microcontroller control module, and a main control module, and further comprising a detection module. The DIP switch module is connected to the detection module, the microcontroller control module is connected to the detection module, and the main control module is connected to the microcontroller control module. After receiving the analog signal from the DIP switch module, the detection module communicates with the main control module via serial port through the microcontroller control module. The main control module transmits signals to the LED cabinet.

[0006] In some embodiments, the DIP switch module includes row DIP switches and column DIP switches.

[0007] In some embodiments, the detection module includes an ID module functional circuit and a detection circuit.

[0008] Compared with the prior art, the beneficial effects of this application are as follows: Unlike the prior art, the automatic positioning device for LED display cabinets provided in this application embodiment is equipped with a hardware detection circuit, which realizes the detection of LED cabinet ID through hardware connection. Unlike the previous method of identifying LED cabinet ID through photoelectric transceiver devices, when replacing the cabinet, only the ID module needs to remain unchanged to maintain the original display effect. It allows for flexible replacement of LED cabinets, that is, placing any cabinet in any position, thus improving maintenance and work efficiency. Attached Figure Description

[0011] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0012] It should be noted that, unless there is a conflict, the various features in the embodiments of this application can be combined with each other, all of which are within the protection scope of this application. Furthermore, although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than the module division in the device or the order in the flowchart. Moreover, the terms "first," "second," and "third" used in this application do not limit the data or execution order, but only distinguish identical or similar items with essentially the same function and effect.

[0013] like Figure 1As shown in the figure, this application embodiment provides an automatic positioning device for LED display cabinets, including a DIP switch module 100, a microcontroller control module 300, and a main control module 400, and also includes a detection module 200. The DIP switch module 100 is connected to the detection module 200, the microcontroller control module 300 is connected to the detection module 200, and the main control module 400 is connected to the microcontroller control module 300. After receiving the analog signal from the DIP switch module 100, the detection module 200 communicates with the main control module 400 through the serial port of the microcontroller control module 300. The main control module 400 transmits signals to the LED cabinet.

[0014] In some embodiments, the DIP switch module includes row DIP switches and column DIP switches. The detection module includes an ID module functional circuit and a detection circuit.

[0015] Specifically, the hardware design circuit of the ID module mainly involves transmitting the XY axis coordinate information of the LED cabinet (which can be, but is not limited to, analog signals) to the ID detection module (AD conversion) of the cabinet via a connected device. The ID detection section stores the collected information and sends it to the main controller, which then positions the LED cabinets and sends image signals. The functional circuits of the ID module and the detection circuitry use DIP switches to adjust the row and column coordinates of the cabinet. These DIP switches are divided into row and column switches. The microcontroller queries the status of the I / O ports to determine the row and column coordinates of the cabinet, encodes the coordinate information, and sends it to the main controller via an interface.

[0016] The above embodiment uses a hardware detection circuit to detect the LED cabinet ID via hardware connection. This allows for easy maintenance or replacement of the LED cabinet by simply keeping the ID module unchanged to maintain the original display effect, thus improving work efficiency.
