[0044] (2) Overall protection process

[0045] The large screen as a whole is subjected to waterproof, corrosion-resistant and drop-resistant process treatment, and the specific measures are as follows:

[0046] 1. Waterproof process: the large screen housing adopts a sealed structure design, and the housing joint is sealed with a waterproof sealing ring that is resistant to high temperature and aging, which can effectively prevent underground water and moisture from entering the equipment interior;

[0047] 2. Anti-corrosion process: The shell is made of 304 stainless steel material, and a special anti-corrosion coating (such as polytetrafluoroethylene coating) is applied on the surface, which can effectively resist the corrosion of coal slurry and corrosive gases in the mine;

[0048] 3. Anti-drop process: A buffer and shock absorption structure is set inside the large screen shell, which can withstand a certain degree of impact and vibration, meeting the anti-drop requirements during transportation and use in the coal mine.

[0049] (3) Intelligent function module

[0050] Intelligent display unit recognition and splicing function

[0052] 2. The large screen controller automatically reads the identity information of each display unit through bus communication, achieving automatic recognition of the display units;

[0053] 3. Based on the recognized display unit information, the controller uses image splicing algorithms to automatically splice and fuse the display content of each display unit, forming a complete high-definition display picture, while supporting manual adjustment of splicing parameters to meet different display requirements.

[0054] (4) AI access and application function

[0055] 1. The large screen controller reserves an AI interface, which can access the AI system in the coal mine (such as coal mine safety monitoring AI analysis system, equipment fault diagnosis AI system);

[0056] 2. Through the AI interface, various data processed by the AI system (such as gas concentration anomaly analysis data, equipment fault warning data, personnel positioning analysis data, etc.) are obtained and displayed in a visual manner (such as charts, animations) on the large screen;

[0057] 3. Support intelligent decision-making assistance function based on AI data, such as when the AI system detects that the gas concentration exceeds the standard, the large screen automatically pops up a warning prompt and displays the emergency treatment scheme suggestion.

[0058] (5) Broadcast intercom function

[0059] 1. The large screen is equipped with a voice processing module, a microphone and a loudspeaker, and can be connected with the broadcast system and intercom system in the coal mine;

[0060] 2. The operator can broadcast voice through the microphone, and the broadcast content can be transmitted to each work area through the underground broadcast system;

[0061] 3. Support point-to-point intercom function, operators can make voice calls to the selected designated large screen through the ground or other terminals to realize real-time communication.

[0062] (6) Human-computer voice intelligent interaction function

[0074] 3.5G transmission: built-in 5G communication module, supports coal mine underground special 5G network, with the characteristics of wide coverage, high speed and low latency. When the underground Ethernet or WIFI7 network fails, it can automatically switch to 5G transmission mode to ensure uninterrupted data transmission, and at the same time realize high-speed data interaction between the large screen and the ground remote monitoring center.

[0075] (9) Display brightness intelligent adjustment function

[0076] The large screen is equipped with an ambient light sensor that detects the light intensity of the underground display environment in real time and transmits the detection data to the large screen controller. The controller has a built-in brightness adjustment algorithm that automatically adjusts the display screen brightness based on the light intensity detected by the ambient light sensor:

[0077] 1. When the underground light intensity is strong (such as when the working face lighting is on), automatically increase the display screen brightness to ensure that the display picture is clear and visible;

[0078] 2. When the underground light intensity is weak (such as during non-working hours, lighting is off), automatically reduce the display screen brightness to avoid strong light stimulating the operator's eyes and reduce device power consumption.

[0079] (10) Industrial multi-protocol interface adaptation function

[0080] The large screen is equipped with multiple industrial standard interfaces on the back, supporting multiple industrial communication protocols, including:

[0081] 1. Supports Modbus RTU / TCP protocol, can connect with underground PLC (Programmable Logic Controller), sensors (such as gas sensor, temperature sensor, pressure sensor) and other devices to obtain device running data and sensor detection data;

[0082] 2. Supports Profinet protocol, can communicate with Siemens series industrial devices in coal mine;

[0085] (11) Remote networking management function

[0086] The large screen is equipped with a remote management module that supports communication with the ground remote management platform through Ethernet and 5G network;

[0087] 1. The remote management platform can obtain real-time operating status information of the large screen (such as display brightness, temperature, voltage, current, working status of each functional module, etc.) and remotely monitor the large screen;

[0088] 2. Supports remote parameter configuration. Administrators can remotely set and modify the display parameters (such as brightness, contrast, and resolution), alarm parameters (such as alarm threshold and alarm method), and transmission parameters (such as transmission rate and transmission protocol) of the large screen through the remote management platform.

[0089] 3. It has remote fault diagnosis and maintenance functions. When the large screen malfunctions, the remote management platform can automatically detect the fault type and location and send fault prompt information to the management personnel. For some simple faults (such as software faults), remote repair can be performed through the remote management platform, reducing the workload of on-site maintenance in the well.

[0090] (12) High-definition display with timer and loop playback function

[0091] 1. The large screen adopts a full-color small-pitch display screen and a small-pitch intrinsically safe high-definition display screen. The pixel pitch is small (such as 1.2mm, 1.5mm), the display resolution is high (supports 4K and 8K high-definition display), the color reproduction is good, and it can clearly display various information such as underground monitoring videos, equipment operation data, and production reports;

[0092] 2. Supports high-definition display and timed playback function. Operators can set the playback schedule through the local operation interface of the large screen or the remote management platform, and preset the display content for different time periods (such as displaying production scheduling information during working hours and displaying safety training videos during off-hours). After the preset time, the large screen will automatically switch to the corresponding display content.

[0093] 3. Supports loop playback function. Multiple contents that need to be displayed repeatedly (such as safety operating procedures, equipment maintenance knowledge, underground escape route map) can be set as a playlist. The large screen will play the contents of the playlist in a preset order. The playback interval and playback duration can be flexibly set.
