Detailed Implementation

[0018] like Figure 1 As shown, the digital monitoring system for safety during the construction of an exploration tunnel for a pumped storage power station of this utility model includes a digital monitoring system platform 10 and its connected modules: a personnel positioning system module 20, a video monitoring system module 40, an environmental monitoring system module 50, an information dissemination system module 60, and a blasting early warning system module 30. Among these,

[0019] The digital monitoring system platform displays information on workers, vehicles, equipment, blasting operations, environmental data, and images of the construction site. The platform includes a processing unit and a display unit. The processing unit receives worker information, equipment information, environmental data, and images of the pumped-storage power station exploration tunnel construction scene from the personnel positioning system module, blasting early warning system module, environmental monitoring system module, and video monitoring system module, respectively. The display unit then shows these information.

[0020] The personnel positioning system module collects real-time information on workers, visitors, and personnel within the tunnel, and transmits this information to the digital monitoring system platform. Worker information includes name, employee ID, contact number, facial image, attendance records, location information, and work trajectory information. The module primarily consists of a positioning base station 21 and a positioning unit 22, both connected to the digital monitoring system platform. The positioning base station can be a 2.4G regional positioning device, a UWB high-precision positioning device, or a device combining both. The positioning base station also communicates with the positioning unit to calculate worker location information and transmit it to the digital monitoring system platform. The positioning unit is embedded in a safety helmet or wearable device (such as a smart bracelet) to collect personnel positioning information and transmit it to the digital monitoring system platform.

[0021] The positioning unit communicates wirelessly with the positioning base station, which in turn communicates wirelessly with the digital monitoring system platform. The positioning base station and positioning unit communicate in real-time or at preset intervals. Based on the communication, the distance and direction of the positioning unit relative to the positioning base station can be calculated. The positioning base station, by adding its own position to the distance and direction of the positioning unit relative to the base station, can determine the location information of the positioning unit, which is the location information of the workers. The positioning base station sends the location information of all workers to the digital monitoring system platform. The digital monitoring system platform updates the worker positions displayed on its display unit based on the worker location information sent by the positioning base station and generates the workers' work trajectories based on the worker location information received multiple times.

[0022] The personnel positioning system module may also include a hazard warning unit (not shown) that is wirelessly connected to the digital monitoring system platform. This hazard warning unit can be built into a safety helmet or wearable device. After receiving the location information of the workers, the digital monitoring system platform will calculate the distance from the dangerous area of ​​the construction site. When the distance is less than the preset distance, the digital monitoring system platform will send a warning command to the hazard warning unit to control the hazard warning unit to issue a warning. The alarm can be issued through one or more of the following forms: vibration, sound, or flashing lights.

[0023] The video surveillance system module collects real-time images of the construction site and sends them to the digital monitoring system platform. This module consists of multiple cameras installed within the construction site. These cameras capture real-time images of the pumped storage power station's exploration tunnel construction scene and transmit them to the digital monitoring system platform. The platform uses a built-in image recognition model to detect and identify any abnormal or illegal behavior by workers in the images, such as not wearing safety helmets. It also identifies any abnormalities in the equipment used in the images. If any abnormalities are found, the platform marks the abnormal locations in the images and activates an alarm.

[0024] The environmental monitoring system module collects environmental data within a preset range and sends it to the digital monitoring system platform. The platform then generates and sends environmental processing instructions and / or alarm commands to the module, which responds accordingly. The module primarily consists of an environmental monitoring unit, an environmental processing unit, and an environmental early warning unit, all connected to the digital monitoring system platform. The environmental monitoring unit collects environmental data and sends it to the platform. The environmental processing unit includes dust removal devices, hazardous gas sensors, and wastewater treatment stations. It receives and responds to environmental processing instructions from the platform and issues warnings. Specifically, the environmental early warning unit receives warning commands from the platform and issues warnings.

[0025] The environmental monitoring unit utilizes methods such as advanced detection, emission, ventilation, protection, grouting for gas containment, and airtight concrete sealing for monitoring. Advanced geological forecasting is used to conduct advance detection of the area from the excavation face to the front, understanding its geological structure and gas content. For detected gas-bearing layers with well-developed fractures and good connectivity, or large gas pockets, advance drilling is performed to identify harmful gases and release them through boreholes. Before each excavation operation, local drilling is intensified to detect the area in front of the excavation face and determine if any harmful gases are escaping. The digital monitoring system platform analyzes the received environmental data, identifies environmental data that does not meet preset standards, and issues corresponding processing instructions to the environmental processing unit and / or early warning instructions to the environmental early warning unit. After receiving environmental processing instructions from the digital monitoring system platform, the environmental processing unit will respond by using preset methods to reduce non-compliant environmental data until it meets the preset standards. For example, if the digital monitoring system platform determines that the concentration of toxic and harmful gases and dust, such as methane, carbon monoxide, hydrogen sulfide, PM, etc., exceeds the national standard, it will issue a dust suppression instruction to the dust removal device. Upon receiving the instruction, the dust removal device will activate its dust removal function to reduce the dust concentration at the construction site. Similarly, if the digital monitoring system platform determines that the carbon monoxide concentration emitted after a dump truck passes by exceeds the standard, it will issue a carbon monoxide reduction instruction to the processing workstation. Upon receiving this instruction, the processing workstation will activate its ventilation system to reduce the carbon monoxide concentration. Ventilation is the most effective means of reducing the concentration of toxic and harmful gases and preventing their accumulation. Ventilation continuously introduces fresh air into the tunnel, removes harmful gases, and reduces dust concentration, thereby improving the construction environment inside the tunnel, ensuring construction safety and human health, and increasing production efficiency. After receiving the warning instruction sent by the digital monitoring system platform, the environmental early warning unit can issue an alarm in the form of a buzzer to remind workers to wear gas masks when entering or leaving the cave.

[0026] The information publishing system module is used to display in real time the following information about construction workers inside the tunnel: team information, personnel details, entry and exit times, toxic and harmful gas data, safe step distance monitoring values, construction procedures, safety notices, project information, welcome messages, dates and times, safety education and training, group promotional videos, on-site meetings, etc. Users can adjust the displayed content as needed. The information publishing system module mainly consists of a media controller 61 and its connected LED display screen 62, LED processor 63, and display controller 64. The media controller communicates with the digital monitoring system platform to publish and display the above information in real time.

[0027] The blasting early warning system module collects blasting information and sends it to the digital monitoring system platform. This module also communicates with the blasting equipment and vehicles on the construction site to collect their information in real time, which is then transmitted to the digital monitoring system platform. The equipment information can include the location and operating status of the equipment, such as dump trucks, concrete mixer pump trucks, bulldozers, excavators, and road rollers.

[0028] The blasting early warning system module mainly consists of a blasting early warning monitoring platform 31 and its connected blasting early warning components 32 and audible and visual alarms 33. The blasting early warning components and audible and visual alarms are installed on the tunnel wall. The blasting early warning components provide blasting early warnings during construction operations and send the blasting early warning data to the audible and visual alarms. The audible and visual alarms receive the blasting early warning data from the blasting early warning components. Upon receiving instructions from the early warning platform and the blasting early warning components, the audible and visual alarms emit a high-volume alarm sound and a strong flashing LED light to quickly alert on-site personnel to take shelter or evacuation measures. The blasting early warning monitoring platform is communicatively connected to the digital monitoring system platform, which sends early warning data to the blasting early warning components and audible and visual alarms.

[0029] The blasting early warning system module is designed to address potential emergencies during the construction of exploration tunnels for pumped-storage power stations. It provides rapid and effective alarm and preventative measures to ensure the safety of construction personnel and reduce losses caused by emergencies. The blasting early warning system consists of a central control unit and distributed sub-units. The main unit is typically installed in the monitoring center or duty room, while the sub-units are deployed at key locations on the construction site, such as the work face, construction vehicles, and wellhead. In case of an emergency, staff at the monitoring center or on-site workers can immediately trigger the nearest one-button alarm device. Once triggered, the alarm devices in the relevant area will immediately activate, emitting a high-volume alarm sound and flashing LED lights to quickly alert personnel to take evacuation or shelter measures. The system supports point-to-point and point-to-many precise control area alarm modes, ensuring that information can be transmitted to all relevant personnel in the shortest possible time, improving the accuracy and efficiency of the response. The equipment features a simple design, easy operation, clear alarm signals, and a low failure rate and long-term durability. This makes it an ideal choice for the safety protection of underground engineering projects, effectively improving the safety management level of underground engineering projects, strengthening the safety protection capabilities of underground engineering projects in my country, and providing strong guarantees for the safe operation of similar projects.
