[0031] like Figure 1 As shown, in a preferred embodiment, an AR-based visualization-based confined space gas distribution monitoring system is provided. In terms of composition, it includes multiple sensors, a positioning module, a human motion detection module, a communication module, an AR interactive terminal, an alarm device, and a monitoring platform server. In terms of connection or installation location, the multiple sensors are respectively arranged within the confined space, with their detection data output terminals connected to the first data input terminal of the communication module. The positioning module collects the three-dimensional position information of the worker, and its positioning data output terminal is connected to the second data input terminal of the communication module. The human motion detection module detects the worker's movement state, and its movement state data output terminal is connected to the third data input terminal of the communication module. The data output terminal of the communication module is connected to the first data input terminal of the monitoring platform server, the data output terminal of the alarm device is connected to the second data input terminal of the monitoring platform server, and the data output terminal of the monitoring platform server is connected to the data input terminal of the AR interactive terminal. The navigation path information data output by the monitoring platform server is displayed through the AR interactive terminal.

[0032] The working principle of the above embodiments is as follows:

[0033] This system integrates a high-precision positioning module, multiple gas sensors, a wireless communication module, and an AR interactive terminal, enabling comprehensive safety monitoring of construction workers in confined spaces and displaying escape routes in dangerous situations. The high-precision positioning module employs advanced positioning technologies such as ultra-wideband (UWB) positioning, inertial navigation, and map-matching positioning, combined with satellite positioning systems (GPS, BeiDou) to achieve precise positioning within confined spaces. This module can acquire the wearer's three-dimensional location information in real time and transmit it to the monitoring platform via the wireless communication module. The multi-modal sensor design utilizes a multi-mode sensor array; specifically, the system incorporates sensors for toxic and harmful gases such as carbon monoxide, hydrogen sulfide, and sulfur dioxide, enabling real-time detection of gas composition and concentration in the surrounding environment. These sensors are characterized by high sensitivity and rapid response, accurately reflecting the gas conditions in the environment. For communication, the wireless communication module supports multiple communication protocols, including LoRa, Bluetooth, and 4G / 5G, ensuring stable data transmission even in complex environments. When an anomaly is detected, a corresponding alarm device can be triggered, which quickly transmits the alarm information to the monitoring platform for immediate alerts. AR interactive terminals, such as AR glasses, can use UWB to locate node coordinates and combine sensor data with existing 3D modeling engines to generate spatial gas concentration heat maps. The results are then displayed on the display module of the AR interactive terminal through a 3D mapping engine, and the navigation path can also be displayed.

[0034] The working process of the above embodiments is as follows:

[0035] Based on this system, the gas concentration and location information in the environment can be read cyclically, and the data can be transmitted back to the monitoring platform via wireless communication, thus providing intuitive data support for the personnel wearing the device and for environmental monitoring. Please refer to [link / reference]. Figure 1 The following is a detailed description of the work process using an oil pipeline maintenance scenario as an example:

[0036] Within the oil pipeline, corresponding sensor nodes (including CO / H2S / CH4 sensors + UWB positioning) are deployed every 10 meters. Before entering the confined space, staff wearing AR interactive terminals turn on the power switch. The system performs a self-test, including the positioning module, gas sensors, and communication module. After passing the self-test, it enters standby mode, and the screen displays that the equipment is ready. It can cyclically read the gas concentration and equipment positioning information in the environment at 1-second intervals. The gas sensors monitor the concentration of toxic and harmful gases such as carbon monoxide and hydrogen sulfide in real time, and the positioning module uses UWB, GPS, and Beidou technologies to obtain the real-time location information of the staff. The human motion detection module uses accelerometers and gyroscopes to monitor the staff's movement status in real time.

[0037] After data collection, the collected gas concentration data, location information, and human movement status data can be transmitted to the monitoring platform server via 4G / 5G networks. The monitoring platform server receives the data, displays and stores it in real time for management personnel to monitor and analyze. When AR functionality is required, the AR interactive terminal receives data pushed by the server and uses the existing AR 3D modeling engine to render gas concentrations and display navigation paths. For example, it can plan paths and overlay arrow guidance (avoiding areas with concentrations >100ppm). When emergency response and rescue are needed, the AR interface can be set to flash red when the concentration is abnormal, and the navigation path can switch to the nearest ventilation vent.

[0038] In summary, this utility model provides an AR-based visualization-based confined space gas distribution monitoring system that can monitor the concentration of toxic and harmful gases and the status of personnel in confined spaces in real time, providing accurate location information and timely alarm functions. This not only improves the safety of personnel but also provides crucial support for emergency rescue, effectively reducing the risks of confined space operations. Furthermore, this utility model overcomes the passive response limitations of traditional alarm devices, significantly improving the safety and emergency response efficiency of confined space operations through gas distribution visualization and navigation, making it particularly suitable for high-risk scenarios such as petrochemical plants and municipal pipeline networks.

[0039] The remaining technical features in this embodiment can be flexibly selected by those skilled in the art to meet different specific practical needs. However, it is obvious to those skilled in the art that these specific details are not necessary to implement this utility model. In other instances, to avoid obscuring this utility model, well-known components, structures, or parts are not specifically described, and all are within the scope of technical protection defined by the claims of this utility model.

That is, the expression of the written language can flexibly correspond to the implementation of the actual technology. The expression of the written language (including the drawings) in the specification of this utility model does not constitute any single limiting interpretation of the claims.
