Description

Technical Field

[0001] The present invention relates to the technical field of video monitoring, and in particular to a video monitoring system and method. Background Art

[0002] Due to the small and closed space of confined space working environments such as underground cable wells, closed pipelines, underground ditches, etc., the signal attenuation is serious. It is difficult for traditional video surveillance equipment to achieve effective video signal transmission, and it is easy to form monitoring blind spots in complex structures, especially at the bottom of deep wells and corners with poor ventilation. The operators and key operating steps cannot be fully covered, which poses a great safety risk. Secondly, confined spaces are often accompanied by flammable, explosive, toxic and harmful gases (such as methane, hydrogen sulfide, carbon monoxide, etc.), and the natural ventilation conditions are poor. Once the gas concentration in the environment suddenly changes or the oxygen content decreases, it is very easy to cause poisoning, suffocation or fire and explosion accidents. Traditional monitoring equipment lacks real-time environmental information collection and early warning capabilities, and cannot provide effective early warning and emergency treatment before the danger occurs, resulting in the inability of operators to respond in time, posing serious safety hazards.

[0003] In addition, the existing monitoring system and environmental monitoring equipment data are relatively independent, making it difficult to achieve comprehensive monitoring and intelligent analysis of the working site environment and the behavior of operators, resulting in an inability to effectively identify the source of danger when an abnormal situation occurs. Furthermore, there may be explosive gases in a confined space working environment, and if conventional equipment does not adopt an explosion-proof design, it is easy to cause sparks due to static electricity or equipment failure during use, thereby causing secondary disasters such as fire or explosion, and lacks adaptability to dangerous environments.

The Mesh network has a high degree of self-organizing network function through direct communication between nodes. It does not require the intervention of a central controller.

When a node fails or the signal quality decreases, the self-healing mechanism of the Mesh network will be activated immediately to automatically find the best communication path to ensure that the signal transmission in the operating area is not affected. This dynamic adaptive capability effectively solves the problem of signal blind spots caused by obstacles or complex terrain in limited space working environments, and greatly improves the signal coverage and transmission quality.

[0050] Furthermore, when the data collection and warning unit 200 detects dangerous parameters, it automatically starts an audible and visual alarm, and transmits the alarm information to the remote monitoring platform, thereby achieving early warning and rapid response.

[0051] The rest of the structure is the same as that of Example 2.

[0052] Operation process: This project integrates wireless AP and Mesh network technology to form a stable and efficient wireless local area network (WLAN), solving the problems of separate wiring of power supply and power supply, complex networking, and difficult construction in limited space operations. Wireless AP uses PoE (Power over Ethernet) technology, integrating power and data transmission functions, so that the power supply and data cables are combined in the same cable, avoiding the trouble of separate wiring of power and data in traditional equipment, greatly simplifying the construction process, and improving installation efficiency and safety. In a limited space, in order to improve wireless signal coverage and transmission stability, a Mesh network architecture is adopted. This architecture forms a self-organizing network between each AP node to ensure that each operation area can obtain stable signal coverage, and solves the problem of congestion and unstable signal in traditional wireless network relay amplification by automatically optimizing the signal transmission path.

[0053] From a technical point of view, the AP module 402 is the basic unit for building a wireless network. Each AP module 402 covers a radius of about 30 meters and can provide high-quality wireless signals for operators. The core of the system lies in the application of Mesh network. The traditional repeater amplification method often simply extends the signal coverage distance, but it will lead to reduced transmission bandwidth and increased delay. Especially in limited space operations with multiple obstacles, this method is prone to cause network congestion and reduced signal transmission quality. The Mesh network has a high degree of self-organizing network function through direct communication between nodes. It does not require the intervention of a central controller. Each AP module 402 can directly form a network connection with neighboring nodes. When a node fails or the signal quality decreases, the self-healing mechanism of the Mesh network will start immediately, automatically find the best communication path, and ensure that the signal transmission in the operating area is not affected. This dynamic adaptive capability effectively solves the problem of signal blind spots caused by obstacles or complex terrain in limited space working environments, and greatly improves the coverage and transmission quality of signals.

[0054] In terms of specific design methods, the characteristics of limited space are first considered, such as the closedness of underground space, tunnel or underground working environment, the density of obstacles and signal attenuation characteristics. In order to ensure that each working area can receive a stable signal, the layout of AP module 402 follows the principles of uniform distribution, optimal signal coverage and minimum signal interference. Each AP module 402 not only serves as a signal transmitting node, but also as a routing node in the Mesh network, and can play the role of data forwarding in the network. Therefore, multiple AP modules 402 are automatically connected wirelessly to form a highly flexible network structure. By superimposing multiple AP modules 402, the network coverage can be expanded to adapt to more complex working scenarios. The installation process of each AP module 402 is simple and can be installed only through a PoE power supply cable. There is no need to lay additional power cables, which effectively reduces the workload and cost of complex construction.

[0055] In order to ensure the reliability and stability of the Mesh network in limited space operations, special attention is paid to the redundancy and self-healing ability of the network during design. In actual applications, the operating environment may change dynamically, such as the movement of operating equipment, the flow of personnel or changes in environmental conditions, which will affect the network signal. The Mesh network can automatically adjust the communication links between nodes according to these changes, select the optimal path for data transmission in real time, and ensure the continuity and stability of the signal transmission process. Even if an AP node is disconnected due to environmental changes, other AP nodes can quickly reroute data through the self-healing function, thereby avoiding failures in the entire network system or local signal blind spots. In addition, when adding AP module 402 to expand the network, the new module only needs to join the network to automatically integrate into the existing Mesh structure without rewiring or configuration, which greatly improves the scalability and operability of the system.

[0056] The design is also particularly suitable for complex limited space scenarios, such as underground mines, tunnel construction or closed underground facilities. Traditional monitoring equipment often faces problems such as insufficient signal coverage, signal attenuation or increased delay in these environments, while the Mesh network can ensure stable signal transmission in environments with dense obstacles and complex paths through the collaborative work of multiple AP modules 402. Through the signal superposition of multiple nodes and self-organizing network technology, the signal can effectively bypass obstacles and maintain high transmission efficiency and quality.

[0057] The design takes into account the high security and monitoring requirements in confined space operation scenarios. Therefore, this system can achieve efficient monitoring and real-time data transmission of on-site operations. Operators can transmit video monitoring signals, environmental monitoring data, etc. to the monitoring center in real time through the AP+Mesh network. Guardians can conduct all-round visual monitoring of the operating environment to ensure operational safety. When abnormal situations occur, the high stability of the Mesh network ensures the continuity of data transmission, allowing the monitoring system to issue early warnings in a timely manner to avoid potential safety hazards.

[0058] During the implementation of the entire system, the number and layout of AP modules 402 are designed according to the complexity of the on-site environment. Through early environmental simulation and signal testing, the best AP distribution plan is determined to ensure the uniformity of signal coverage and the optimization of network paths. During specific operations, technicians use professional signal analysis tools to detect the signal strength and transmission quality of each node in real time, adjust the location of AP nodes or increase the number of nodes for possible interference sources or coverage blind spots, and finally form a complete wireless network coverage.
