Description

Technical Field

[0001] This disclosure relates to the field of monitoring technology, and in particular to a display control method and device, electronic equipment and storage medium for a mine safety monitoring system. Background Technology

[0002] Intelligent safety monitoring systems for coal mines require centralized monitoring of production information through display devices, while integrating multiple signals to meet centralized control needs. However, traditional solutions have significant shortcomings in the harsh environment of coal mines. Traditional display devices often employ packaging methods with inadequate protection, making key components susceptible to dust and moisture corrosion, leading to malfunctions. Poor heat dissipation during high-brightness operation affects equipment lifespan and stability; pursuing better display effects may reduce system reliability. Furthermore, maintenance is cumbersome and difficult to repair quickly. Related heat dissipation designs also suffer from high noise and energy consumption, failing to meet the requirements of green mine construction. Even with some improvements in packaging technology, there are still issues of easy damage and limited improvement in luminous efficiency. Regarding multi-signal source centralized control, traditional solutions rely on complex equipment operation and slow response, lacking flexible signal display. Conflicts easily arise during collaborative operations, emergency scenario switching efficiency is low, and additional intermediate devices are required to connect to different devices, resulting in a complex system architecture, low integration, and inability to meet actual usage needs.

[0011] It should be understood that the description in this section is not intended to identify key or essential features of the embodiments of this disclosure, nor is it intended to limit the scope of this disclosure. Other features of this disclosure will become readily apparent from the following description. Attached Figure Description

Detailed Implementation

[0013] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0014] The following description, with reference to the accompanying drawings, outlines a mine safety monitoring system display control method and apparatus, electronic device, and storage medium according to embodiments of the present disclosure.

[0015] Figure 1 This is a flowchart illustrating a display control method for a mine safety monitoring system provided in an embodiment of this disclosure.

[0016] like Figure 1 As shown, the method includes the following steps: Step 101: Construct a mining display surface composed of multiple high-protection-level display modules spliced ​​together, wherein the display modules adopt flip-chip direct electrical connection with the substrate and form an integrated sealed planar light-emitting structure through encapsulation material.

[0017] In the embodiments of this disclosure, to meet the high protection and high reliability requirements of display devices in harsh industrial environments such as coal mines, multiple high-protection-level display modules are spliced ​​together when constructing the mining display surface. The core design of the display module lies in achieving direct electrical connection between the chip and the substrate through flip-chip bonding, abandoning the traditional vulnerable connection structure. Then, encapsulation materials are used to completely encapsulate the connection area between the chip and the substrate, as well as the light-emitting surface, forming a sealed planar light-emitting structure with no exposed components and an integrated structure. This structurally improves the module's dustproof, moisture-proof, and external corrosion resistance, while ensuring the stability of the electrical connection. This integrated sealed structure can prevent damage to the core light-emitting and connecting components from harsh external environments, optimize heat conduction paths, and balance protection performance with thermal management effects. The splicing design of multiple such modules can flexibly adapt to different display surface size requirements in mining scenarios. As one implementation method, the encapsulation material can be selected from materials with high light transmittance, high thermal conductivity, and environmental corrosion resistance, and the substrate can be made of a high thermal conductivity substrate to further enhance the reliability of the module.

[0018] Through structural optimization, the display module achieves high protection and high stability, effectively solving the problem that traditional display devices are prone to failure due to external corrosion or connection failure in harsh mining environments. The splicing design takes into account size flexibility, enabling the mining display surface to operate stably for a long time and adapt to the continuous working needs of the coal mine intelligent safety monitoring system.

[0019] Step 102: Access the multi-source heterogeneous monitoring signals in the mine through a distributed signal processing system, process the signals in a unified manner, and generate a network data stream that can be visualized and dragged and laid out on the control interface.

[0020] In the embodiments of this disclosure, to meet the need for centralized visualization of multiple types of monitoring data in intelligent safety monitoring scenarios in coal mines, this solution adopts a distributed signal processing system (i.e., a distributed architecture signal processing unit based on network interconnection and composed of multiple functionally related nodes). Its core lies in achieving unified access and standardized processing of multi-source heterogeneous monitoring signals in the mine. This system is compatible with different types and transmission protocols of signals, and can uniformly convert, encode, and format various monitoring signals, transforming dispersed heterogeneous signals into network data streams with a unified data format. Furthermore, this network data stream supports visual layout configuration on the control interface, allowing for flexible adjustment of the signal display layout through intuitive operation. As one implementation method, the distributed signal processing system may include signal acquisition nodes and data distribution nodes, supporting access to various signals such as video surveillance and production data. The network data stream generated after unified processing can realize layout operations such as windowing, scaling, and cross-region display of signals on the display surface.

[0021] Therefore, it can solve the problems of complex access to traditional multi-source signals, rigid processing architecture, and inconvenient layout adjustment, improve the integration and flexibility of mine monitoring signal processing, reduce the difficulty of unified management of multiple heterogeneous signals, ensure that signal display can quickly adapt to different display needs in safety supervision scenarios, and enhance the signal processing efficiency and ease of operation of coal mine intelligent safety supervision system.

[0022] Step 103: Perform regional timing power-on management on the mining display surface, and adaptively adjust the driving parameters of the corresponding display areas based on the operating status information collected by the sensors integrated in the display module.

[0023] In the embodiments of this disclosure, to ensure the stable startup and continuous reliable operation of the mining display surface, this solution implements regional sequential power-on management. By setting a reasonable power-on sequence, different display areas are started sequentially, avoiding the risk of power surges caused by concentrated power-on. Simultaneously, sensors are integrated into each display module to collect its operational status information in real time. Based on this status information, the driving parameters of the corresponding display area are adaptively and dynamically adjusted to match the real-time operating conditions of the module, ensuring that the display surface maintains stable performance even in complex environments. As one implementation method, the regional sequential power-on logic can be executed through a programmable control module. Sensors can collect operational status data such as temperature and current, and driving parameters can include brightness and power. When an abnormality is detected in a certain area, the parameters are automatically adjusted to optimize the operating effect.

[0024] Therefore, it can solve the problem of surge impact caused by traditional centralized power supply and the defect that fixed drive parameters cannot adapt to changes in working conditions, significantly improving the start-up stability and long-term operational reliability of mining display panels. At the same time, it achieves energy-saving optimization through adaptive parameter adjustment, further adapting to the operating requirements of the harsh industrial environment of coal mines.

[0025] Step 104: When the distributed signal processing system or the mining display surface detects a pixel-level anomaly, a pixel compensation mechanism is triggered to maintain the integrity of the image, and an anomaly report containing a precise location identifier is generated simultaneously.

[0026] In the embodiments of this disclosure, to ensure the display continuity and ease of operation and maintenance of the mining display system, this solution endows the distributed signal processing system and the mining display surface with pixel-level anomaly detection capabilities. When either module detects a pixel-level anomaly, the system will automatically trigger a preset pixel compensation mechanism. By adjusting the signals or adapting the functions of the surrounding display resources of the anomaly pixel, the display loss caused by the anomaly pixel is compensated, ensuring the integrity of the overall image and the accuracy of information transmission. Simultaneously, the system will generate an anomaly report, which includes the precise location identifier of the anomaly pixel, providing a clear location basis for operation and maintenance work. As one implementation method, pixel-level anomalies may include the loss of control of a single pixel. The pixel compensation mechanism may employ a surrounding pixel parameter correction algorithm. The anomaly report may be simultaneously pushed to the control platform and the anomaly location may be marked to assist in quickly carrying out maintenance operations.

[0027] Therefore, it can solve the problems of easy image damage and low maintenance efficiency caused by unclear fault location when traditional display devices have abnormal pixels. It not only ensures the complete presentation of key monitoring information in coal mine safety supervision scenarios, but also greatly improves the accuracy and efficiency of fault diagnosis and maintenance, and further enhances the convenience of operation and maintenance and the reliability of mining display systems.

[0028] The mine safety monitoring system display control method disclosed herein constructs a display module splicing mine display surface, utilizes a distributed signal processing system to uniformly process multi-source heterogeneous monitoring signals in the mine and generate a network data stream that can be visualized and dragged for layout, performs regional time-sequential power-on management of the mine display surface and adaptively adjusts the corresponding display area driving parameters based on the operating status information collected by sensors, and triggers a pixel compensation mechanism when a pixel-level anomaly is detected and simultaneously generates an anomaly report with precise location identification. Therefore, it can solve the problems of poor protection performance of display devices, complex and rigid multi-source signal processing, inconvenient layout operation, loss of image integrity when pixels are abnormal and difficulty in fault location and maintenance in the prior art, and achieves the technical effect of mine display system with high protection and reliability, flexible and intuitive multi-source signal processing, accurate fault location and convenient maintenance, and adaptability to the intelligent safety monitoring display and control needs of the harsh industrial environment of coal mines.

[0029] As a specific embodiment of this disclosure, based on the basic scheme, the construction of a mining display surface composed of multiple high-protection-level display modules is further defined as follows: using a metal-based composite material as a circuit substrate, bonding flip-chip LEDs to the circuit on the substrate through bumps; using an insulating encapsulation material with high thermal conductivity and high light transmittance to encapsulate the bonded structure as a whole, forming a sealed light-emitting unit with no uneven surface and no exposed conductive parts; wherein, multiple sealed light-emitting units are mechanically spliced ​​to form a large-size display surface, and the overall display surface after splicing meets the dustproof and water-sprayproof requirements in mines.

[0030] Specifically, when constructing a mining display surface, a metal-based composite material with high thermal conductivity (such as aluminum-based composite material) is selected as the circuit substrate. This substrate can provide a stable carrier for subsequent signal transmission and heat dissipation. The electrodes of the flip-chip are precisely and directly bonded to the circuit pattern preset on the substrate surface through a bump structure, abandoning the traditional wire bonding method and reducing the risk of connection failure. Subsequently, an insulating encapsulation material with both high thermal conductivity and high light transmittance (such as transparent resin with high light transmittance and high refractive index) is used to perform overall molding and potting treatment on the chip, bumps, and substrate bonding area. The potting process ensures that the material completely covers the core functional area, ultimately forming a sealed light-emitting unit with a smooth and flat surface, without any uneven structure and no exposed conductive parts. Multiple such sealed light-emitting units are spliced ​​and assembled through a standardized mechanical structure. During splicing, the fitting accuracy of adjacent units is ensured, ultimately forming a large-size display surface that meets the needs of mining scenarios. After overall encapsulation and splicing design, the protective performance of this display surface meets the dustproof and water-spray-proof standards required by the harsh environment of underground mines.

[0031] The heat dissipation capacity is enhanced by using a metal matrix composite substrate. The direct bonding of bumps and the fully sealed potting design completely eliminate the possibility of exposed components being corroded by the environment. The mechanical splicing scheme takes into account both the large size requirements and the protective integrity, effectively improving the reliability and environmental adaptability of the mining display surface, and ensuring its stable operation for a long time in the high dust and high humidity mining environment.

[0032] As a specific implementation of this disclosure, based on the basic scheme, the access to multi-source heterogeneous monitoring signals in the mine via a distributed signal processing system is further defined as follows: acquiring raw signals from video surveillance, sensor networks, and production control systems through multiple input nodes deployed both above and below ground, and encoding and compressing the raw signals into low-latency network streams; receiving specified network streams through multiple output nodes according to control instructions, performing decoding and image overlay processing, and then driving the corresponding area of ​​the mine display surface to display; wherein, in the control interface, using the virtual mapping map of the mine display surface as the operation background, cross-screen roaming, scaling, and layer management of the signal window are achieved by dragging the signal source icon to any position on the virtual mapping map.

[0033] Specifically, the distributed signal processing system consists of multiple input and output nodes deployed underground in the mine and in the surface centralized control area. All nodes are interconnected through network switches. The input nodes are equipped with interfaces compatible with multiple signal types, enabling them to comprehensively acquire raw signals from underground video monitoring equipment, sensor networks (such as environmental monitoring and equipment status sensors), and production control systems (such as SCADA systems). After acquisition, low-latency encoding and compression algorithms (such as H.264 / H.265) are used to convert the raw signals into standardized network streams, ensuring efficient and real-time signal transmission. The multiple output nodes correspond to the various display areas of the mine's display surface. They can accurately acquire the specified network stream according to the received control commands, decode it, perform image overlay operations to adapt to the simultaneous display requirements of multiple signals, and then drive the corresponding display areas to complete the signal presentation. In the control interface, the system constructs a virtual mapping map that is consistent with the actual layout of the mine display surface as the operation background. Users can directly grab the signal source icon in the interface and drag it to any position in the virtual mapping map. This operation will be synchronously converted into control commands and sent to the output node, thereby realizing cross-screen roaming of the signal window, free scaling, and hierarchical adjustment and management of different signal layers.

[0034] The distributed node architecture enables efficient access and flexible distribution of multi-source heterogeneous signals. Combined with intuitive drag-and-drop operation, it simplifies the signal layout adjustment process and effectively solves the problems of complex signal access, rigid layout, and slow response in traditional solutions. It significantly improves the flexibility and ease of operation of centralized display of multiple signals in the coal mine safety monitoring system and ensures rapid scheduling and accurate presentation of monitoring information.

[0035] As a specific implementation of this disclosure, based on the basic scheme, the implementation of regional time-sequential power-on management for the mining display surface is further defined as follows: according to the preset power-on logic, the power distribution system is controlled to supply power to the core functional area and the edge extension area of ​​the display surface in millisecond-level time differences; the adaptive adjustment of the driving parameters of the corresponding display areas includes: real-time monitoring of the junction temperature of each display area, and when the junction temperature of a certain area exceeds a first safety threshold, automatically reducing the driving current or brightness of that area, and activating the corresponding backup heat dissipation strategy for that area.

[0036] Specifically, when implementing zoned sequential power-on management for mining display surfaces, the system first uses preset power-on logic to clearly define the division and power supply sequence between the core functional area (such as the main monitoring data display area) and the edge extension area of ​​the display surface. The power distribution system (i.e., the intelligent power distribution unit with embedded PLC control module) then supplies power to the core functional area and the edge extension area sequentially at millisecond intervals according to this logic, ensuring a smooth and orderly power supply process and avoiding surge current impacts caused by concentrated power-on. In the adaptive adjustment stage of drive parameters, temperature sensors integrated into each display area collect the junction temperature data of the display module in real time and feed it back to the control module. The system presets a first safety threshold for junction temperature. When the control module detects that the junction temperature of a certain display area exceeds this threshold, it immediately triggers the adaptive adjustment mechanism, automatically reducing the drive current or display brightness of that area to reduce heat generation. At the same time, it activates the corresponding backup heat dissipation strategy for that area. This backup heat dissipation strategy is based on a fanless passive heat dissipation architecture optimization, which further suppresses the continuous rise in junction temperature by enhancing the heat conduction efficiency of the high thermal conductivity substrate and heat dissipation structure.

[0037] Through millisecond-level timing-based regional power-on design, the impact damage of surge current to the power distribution system and display module is effectively avoided. Combined with real-time junction temperature monitoring and graded control strategies, the risk of local overheating can be accurately controlled. The linkage of backup heat dissipation strategies further improves the reliability of system thermal management, ensuring that the mining display surface maintains stable performance during long-term continuous operation, and fully adapts to the harsh industrial power supply environment and operating requirements of coal mines.

[0038] As a specific implementation of this disclosure, the trigger pixel compensation mechanism is further defined on the basis of the basic scheme, including: determining the physical coordinates and logical address of the abnormal pixel on the display surface; calling the grayscale and color data of the normal pixel adjacent to the abnormal pixel, calculating the simulated data used to fill the abnormal pixel through a preset image compensation algorithm, and outputting it to the corresponding driving circuit.

[0039] Specifically, when the pixel compensation mechanism is triggered, the distributed signal processing system first works in conjunction with the built-in detection unit of the mining display surface. Based on the pixel drive signal feedback and the layout mapping relationship of the display surface, the physical coordinates (i.e., actual spatial position) and corresponding logical address (i.e., signal control address in the drive circuit) of the abnormal pixel on the display surface are accurately determined, ensuring the accurate positioning of the abnormal pixel. Then, the system automatically retrieves the grayscale and color data of the adjacent normal pixels within a preset range around the abnormal pixel. The adjacent normal pixels can include the effective display pixels in the vertical, horizontal, and diagonal directions of the abnormal pixel. Next, a preset image compensation algorithm (such as an interpolation compensation algorithm or a neighborhood mean compensation algorithm) is started. The grayscale and color data of the adjacent normal pixels are used as input parameters. The algorithm calculates and generates simulated data that is visually consistent with the surrounding image. This simulated data can match the display style of the area where the abnormal pixel is located. Finally, the calculated simulated data is output to the drive circuit corresponding to the abnormal pixel. The drive circuit controls the pixel position to be displayed according to the simulated data, realizing the visual filling of the abnormal pixel.

[0040] By accurately locating the physical coordinates and logical addresses of abnormal pixels, and combining adjacent normal pixel data with a dedicated compensation algorithm to generate simulated data, the display gaps of abnormal pixels can be quickly and naturally filled. This effectively avoids the impact of a single pixel failure on the integrity of the overall image, ensuring the continuity and clarity of the monitoring screen in coal mine safety supervision scenarios. At the same time, it eliminates the need for immediate shutdown maintenance, further enhancing the continuous operation capability of the display system.

[0041] As a specific implementation of this disclosure, based on the basic solution, the embodiments of this disclosure further include: assigning differentiated signal operation permission sets and display area operation permission sets to monitoring agents with different responsibilities.

[0042] Specifically, the system's intelligent permission management module enables differentiated permission allocation. Administrators can configure dedicated signal operation permission sets and display area operation permission sets for each monitoring agent based on their responsibilities (such as daily inspection agents, emergency command agents, and system maintenance agents). The signal operation permission set is further subdivided by functional level into permissions for signal viewing, signal switching, signal parameter adjustment, and KVM reverse control. The display area operation permission set corresponds to the physical or logical partitions of the mine's display surface, clearly defining the specific display area that an agent can operate (such as the core monitoring area and the edge auxiliary display area). Permission configuration information is stored in the system's intelligent management layer node. When an agent initiates an operation command, the distributed signal processing system and display control module will verify in real time whether the signal source and display area corresponding to the command are within its permission set. Only valid commands are allowed to execute; operations exceeding permissions will be automatically intercepted, and a permission deficiency warning will be displayed, ensuring that the operation behavior accurately matches the agent's responsibilities.

[0043] By assigning refined and differentiated permissions, the system effectively solves the problems of permission confusion and operational conflicts in traditional multi-seat collaborative operations. It not only ensures the operational security of key signals and core display areas, but also enables each seat to focus on operations within its own scope of responsibility. This improves the operational standardization and work efficiency of the coal mine intelligent safety monitoring system and adapts to the multi-role collaborative management and control needs in industrial centralized control scenarios.

[0044] It should be noted that the embodiments of this disclosure may include multiple steps. For ease of description, these steps are numbered, but these numbers are not a limitation on the execution time slots or execution order between the steps; these steps can be implemented in any order, and the embodiments of this disclosure do not limit this.
