Description

Technical Field

[0001] The present disclosure relates to the field of safety technology, and in particular to a coal yard safety monitoring system and method. Background Art

[0002] With the continuous development of the coal industry, coal yards are expanding in size, and the movement of personnel and equipment is increasing. This poses numerous challenges to coal yard safety management. In this complex coal yard environment, accurately understanding the location of personnel and equipment, as well as the actual situation on site, is crucial to ensuring production safety and improving management efficiency. Therefore, the development of an efficient and accurate coal yard safety monitoring system has become an urgent need in the industry.

[0003] Currently, some coal yard safety monitoring solutions primarily employ a single technical approach. For example, some rely solely on positioning systems, deploying base stations and tags carried by personnel and equipment within the yard. The base stations receive identification codes and location data from the tags, determining their corresponding coordinates. Alternatively, some yards employ only video surveillance systems, using cameras to capture real-time video images of various areas of the yard. These single systems can capture some information to a certain extent, but they cannot fully and comprehensively reflect the actual conditions of the yard. Summary of the Invention

[0029] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0030] The coal yard safety monitoring system, method, device, electronic device, and storage medium according to embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0031] Figure 1 A schematic diagram of a coal yard safety monitoring system provided by an embodiment of the present disclosure.

[0032] like Figure 1 As shown, the system includes:

[0033] Positioning system 1, video surveillance system 2, and security management platform 3;

[0034] The positioning system 1 includes a positioning base station and a positioning tag located in the coal yard. The positioning base station is used to receive the identity identification code and location data sent by the positioning tag in real time, determine the positioning coordinates corresponding to the positioning tag based on the identity identification code and location data, and send the positioning coordinates to the security management platform and video surveillance system;

[0035] The video surveillance system 2 is used to collect the surrounding video images of the positioning coordinates in real time and send the surrounding video images to the security management platform;

[0036] The safety management platform 3 is used to generate a dynamic location map of the coal yard based on the positioning coordinates and surrounding video images, combined with a preset coal yard model, so as to perform safety monitoring based on the dynamic location map of the coal yard.

[0037] The disclosed coal yard safety monitoring system consists of three main components: a positioning system, a video surveillance system, and a safety management platform. The positioning system acquires the location information of personnel and vehicles, the video surveillance system captures on-site video images, and the safety management platform integrates location and video information, generates dynamic location maps, and implements safety monitoring. These three components work together to provide comprehensive protection for coal yard safety.

[0038] The positioning system consists of a positioning base station and positioning tags located within the coal yard. The positioning base station, acting as an information receiving node, receives the identification code and location data from the positioning tags in real time. Based on this information, the positioning base station determines the corresponding coordinates of the positioning tags and transmits these coordinates to the security management platform and video surveillance system, providing accurate location information for subsequent security monitoring and video surveillance.

[0039] In some embodiments, the positioning tag includes a personnel positioning tag disposed in a helmet of an operator and a vehicle-mounted positioning tag disposed on a vehicle.

[0040] In some embodiments, the positioning base station is deployed at a fixed position on the top of the coal yard or on the wall to form a cellular coverage network.

[0041] In some embodiments, the positioning base station is used to continuously transmit pulse signals and receive response signals fed back by the positioning tag based on the pulse signals to record the arrival time and arrival time difference of the response signals; based on the arrival time and arrival time difference of the response signals, the positioning coordinates corresponding to the positioning tag are calculated.

[0042] Specifically, the positioning base station is installed in a cellular network layout on the top of the coal yard or at a fixed position on the wall, using ultra-wideband (UWB) or radio frequency identification (RFID) technology. The base station continuously transmits pulse signals. The positioning tag (personnel helmet type or vehicle-mounted type) receives the signal and feeds back a response signal. The base station records the arrival time (TOA) and arrival time difference (TDOA) of the signal and calculates the three-dimensional coordinates of the tag through a positioning algorithm. For example, by calculating the time difference of at least three base stations, the system can accurately lock the tag position to sub-meter accuracy.

[0043] UWB technology uses high-frequency pulse signals to measure the signal's time of flight (TOF) between the base station and the tag, and combines the spherical intersection method of at least three base stations to calculate three-dimensional coordinates with sub-meter accuracy.

[0044] RFID technology uses a receiver to emit a high-frequency electromagnetic field to locate the tag feedback information. The system determines the three-dimensional coordinates based on the signal strength or time difference, and is suitable for large-scale tag management.

[0045] The personnel location tag can be embedded in a helmet, addressing the safety requirements of industrial scenarios and addressing the issue of handheld devices being easily lost. The vehicle location tag can be mounted on the top of a vehicle, featuring a metal-resistant design to ensure stable tracking of moving targets.

[0046] The video surveillance system captures real-time video images of the surrounding area based on the coordinates provided by the positioning system. These images are promptly transmitted to the security management platform, enabling it to intuitively understand the actual situation on site and verify them with the positioning information, improving the accuracy and reliability of security monitoring.

[0047] In some embodiments, the video monitoring system is used to adjust the monitoring angle in real time according to the positioning coordinates, so as to capture surrounding video images of the positioning coordinates according to the monitoring angle.

[0048] Specifically, the video surveillance system integrates a pan / tilt control module. After receiving positioning coordinates from the security management platform, it uses stepper motors to drive the pan / tilt rotation, adjusting the camera's pitch and horizontal angles. The system uses PresetPosition technology to pre-store coordinate and angle mappings for key areas of the coal yard, enabling millisecond-level alignment.

[0049] At the same time, in the low-light environment of the coal yard, the cameras in the video surveillance system can automatically enable infrared thermal imaging mode, combined with digital noise reduction algorithms, to ensure that the image clarity meets safety monitoring requirements.

[0050] The safety management platform is the core of the entire coal yard safety monitoring system. It generates a dynamic coal yard location map based on received positioning coordinates and surrounding video images, combined with a pre-set coal yard model. By integrating location and video information with the coal yard model, it can reflect the dynamic distribution of personnel and equipment within the coal yard in real time, providing intuitive and comprehensive information support for safety monitoring.

[0051] When generating a dynamic coal yard location map, the safety management platform first spatially and temporally aligns the location coordinates and surrounding video images with the static structure of the pre-set coal yard model to create a three-dimensional coal yard model. Then, pre-set layers are layered and overlaid on the 3D coal yard model to create a dynamic coal yard location map. This layered display clearly displays different types of information within the coal yard, allowing managers to quickly understand the on-site situation.

[0052] Preset layer types include static structure layer, dynamic positioning layer, and risk visualization layer. The static structure layer displays the fixed facilities and layout of the coal yard, providing context for dynamic information. The dynamic positioning layer displays the real-time location of personnel and vehicles, reflecting the dynamic changes within the coal yard. The risk visualization layer highlights potential safety risk areas, prompting managers to take timely measures.

[0053] Specifically, the safety management platform imports the coal yard BIM model or laser scanning point cloud data and spatially matches the positioning coordinates with static structures in the model (such as coal retaining walls and conveyor belts). Through a timestamp synchronization mechanism, the real-time video stream is aligned with the positioning data to generate a three-dimensional dynamic map of the coal yard. The static structure layer displays the fixed facilities in the coal yard (rendered in gray and translucent); the dynamic positioning layer marks the real-time location of personnel and vehicles with different colors (red warns of high-risk areas); and the risk visualization layer overlays gas concentration heat maps and high-temperature area warning boxes.

[0054] In some embodiments, the safety management platform monitors safety-related parameters in real time on the coal yard's dynamic location map, including distances between people and vehicles, density of people in an area, and time spent in restricted areas. When these parameters exceed preset safety limits, the safety management platform issues a timely safety warning, allowing management personnel to take appropriate measures to prevent accidents.

[0055] When the distance between people and vehicles is less than or equal to the preset safety distance, the security management platform controls the positioning tag to vibrate and issue a safety warning pop-up to remind people to pay attention to the safe distance; when the population density in the area is less than the preset safety density, the vehicle speed is controlled to the preset safety speed, and the video surveillance system is controlled to monitor people or vehicles in the area in real time to ensure the safety of people and vehicles; when the stay time in the restricted area is greater than or equal to the preset safety period, the equipment in the restricted area is controlled to stop, and a restricted area intrusion information is sent to the responsible person to deal with the violation in a timely manner.

[0056] Specifically, the real-time distance between people and vehicles is calculated through positioning coordinates. If the distance between people and vehicles is less than or equal to 5 meters (preset safety distance), a dual warning is triggered, namely the vibration reminder of the positioning tag and the platform pop-up alarm. The number of people in the unit area is counted. If the number of people in the area exceeds the safety density threshold, a speed limit instruction is sent to the vehicle (such as reducing from 15km / h to 5km / h), and the camera is linked to lock the dense area. Combined with electronic fence technology, if the positioning tag stays in the restricted area for more than 3 minutes (preset safety period), the power supply of the equipment in the area is automatically cut off, and a text message alarm with geo-fence is pushed to the responsible person.

[0057] In summary, this disclosure achieves an upgrade in coal yard safety from "passive response" to "active prevention" through a closed-loop approach involving positioning, video, and platform data. Core technologies include UWB high-precision positioning, pan-tilt dynamic tracking, and 3D GIS mapping. Combined with IoT control logic, this creates an intelligent solution covering the entire chain of "monitoring, early warning, and disposal." This solution comprehensively and accurately captures the location of personnel and equipment within the coal yard, as well as the actual situation on site. This enables comprehensive, real-time monitoring of coal yard safety, significantly improving the efficiency and accuracy of coal yard safety management and providing a strong guarantee for safe production.

[0058] Figure 2 A flow chart of a coal yard safety monitoring method provided in an embodiment of the present disclosure.

[0059] like Figure 2 As shown, the method comprises the following steps:

[0060] Step 101: Determine the positioning coordinates corresponding to the positioning tag based on the identification code and position data corresponding to the positioning tag.

[0061] In the embodiments of the present disclosure, the positioning system of the present disclosure uses ultra-wideband (UWB) or radio frequency identification (RFID) technology to receive in real time the identification code and location data sent by the positioning tag (personnel helmet type or vehicle-mounted type) through a positioning base station deployed in the coal yard. The positioning base station records the arrival time (TOA) and arrival time difference (TDOA) of the signal, and combines it with a triangulation positioning algorithm to calculate the three-dimensional coordinates of the positioning tag, i.e., the positioning coordinates, to achieve sub-meter precision positioning. This ensures the accurate acquisition of the location of personnel and equipment, providing basic data for subsequent monitoring and early warning.

[0062] Step 102: collect surrounding video images of the positioning coordinates in real time.

[0063] In the disclosed embodiments, the video surveillance system uses a pan / tilt control module to adjust the camera angle based on the positioning coordinates, capturing real-time video images around the positioning coordinates. Specifically, the system uses Preset Position technology to pre-store coordinate and angle mapping tables for key areas of the coal yard, enabling millisecond-level rapid alignment.

[0064] Furthermore, in low-light environments, the cameras in the video surveillance system can automatically activate infrared thermal imaging mode, combined with a digital noise reduction algorithm to ensure image clarity that meets security monitoring requirements, providing intuitive visual information for security monitoring.

[0065] Step 103 : Generate a dynamic location map of the coal yard based on the positioning coordinates and the surrounding video images in combination with a preset coal yard model, so as to perform safety monitoring based on the dynamic location map of the coal yard.

[0066] In the disclosed embodiments, the safety management platform spatially and temporally aligns location coordinates, surrounding video images, and a pre-set coal yard model (such as a BIM model or laser scanning point cloud data) to generate a three-dimensional dynamic map of the coal yard. The platform displays a layered overlay of static structure, dynamic positioning, and risk visualization layers, supporting real-time monitoring and early warning of safety parameters. By integrating multi-source data, it enables visual management and intelligent decision-making for coal yard safety.

[0067] At the same time, the present disclosure can also monitor safety-related parameters such as the distance between people and vehicles, the density of people in the area, and the time spent in restricted areas in real time based on dynamic location maps. Once the parameters exceed the preset threshold, the early warning mechanism will be triggered immediately:

[0068] The details are as follows:

[0069] When the distance between the person and the vehicle is too close, that is, when the distance between the person and the vehicle is less than or equal to the preset safety distance, the positioning tag is controlled to vibrate and a safety warning pop-up window is displayed;

[0070] When the density of people in the area exceeds the standard, that is, when the density of people in the area is lower than the preset safe density, the vehicle speed is controlled and people or vehicles in the area are monitored in real time;

[0071] The restricted area stay timeout, that is, when the restricted area stay time is greater than or equal to the preset safety period, the equipment in the restricted area is controlled to stop and a restricted area intrusion information is sent to the responsible person.

[0072] This disclosure achieves active prevention and efficient response to coal yard safety through intelligent algorithms and automated control.

[0073] In summary, the coal yard safety monitoring method provided by the disclosed embodiments determines the location coordinates corresponding to the location tag based on its corresponding identification code and location data; captures surrounding video images of the location coordinates in real time; and generates a dynamic location map of the coal yard based on the location coordinates and surrounding video images, combined with a preset coal yard model, for safety monitoring based on the dynamic location map. This method achieves comprehensive, real-time monitoring of coal yard safety, significantly improving the efficiency and accuracy of coal yard safety management and providing a strong guarantee for safe production in the coal yard.
