Technical Field

[0001] This utility model provides a smart encapsulation and intrinsically safe display screen for mining, belonging to the technical field of mining display equipment. Background Technology

[0002] The underground environment of coal mines is complex, characterized by high humidity, high dust levels, and flammability and explosiveness. To improve production safety, mining display screens, as crucial information transmission equipment, must meet intrinsically safe or explosion-proof requirements. However, existing mining display screens still have the following problems:

[0003] Limited display effect: Traditional mining displays mostly use low-resolution or monochrome display technology, which results in poor visibility in strong light or harsh environments and low information transmission efficiency.

[0004] Insufficient safety: Some equipment does not employ effective sealing and protection measures, making it susceptible to moisture and dust, which can lead to short circuits or equipment failure, posing safety hazards.

[0005] Limited functionality and lack of intelligence: Most mining displays currently only support static or simple scrolling information display, and cannot be remotely controlled or dynamically adjusted, resulting in low flexibility of use.

[0006] Poor structural sealing: Some mining display equipment has a low protection level, and is prone to water ingress, dust ingress or aging problems during long-term use, which affects its service life. Utility Model Content

[0007] To address the problems of poor display quality, poor safety, and poor sealing in existing mining displays, this invention proposes a mining-grade intelligent encapsulated and intrinsically safe display screen. It employs a 1.53mm high-brightness, high-saturation COB full-color screen, supports remote software control of program content, and utilizes a foam-sealed structure, effectively improving the equipment's display quality, safety, and durability.

[0010] Furthermore, the image display module adopts a COB full-color LED module, and the image display module is divided into multiple LED modules.

[0011] Furthermore, the image receiving card consists of multiple image receiving sub-cards connected in series via network cables, and each image receiving sub-card is connected to at least one LED module to receive data from the LED module. The first and last image receiving sub-cards are each equipped with a data network port for receiving control card data, and the last image receiving sub-card is connected to the image control card through the data network port for receiving control card data.
