Description

Technical Field

[0001] This utility model belongs to the field of fire-fighting equipment, specifically a dedicated data transmission line for AIot bottle group status detection. Background Technology

[0002] Gas fire extinguishing equipment (such as heptafluoropropane, IG541, and carbon dioxide fire extinguishing systems) is a core device for ensuring fire safety in high-risk locations such as power facilities, data centers, and chemical plants. The cylinder assembly, as the core component storing the extinguishing medium, needs to be kept under high pressure and sealed conditions for extended periods. If leakage, abnormal pressure, or environmental factors cause performance degradation, it may lead to fire extinguishing failure or safety accidents.

[0003] AIoT, or Artificial Intelligence of Things, combines AI (Artificial Intelligence) and IoT (Internet of Things). AIoT integrates AI and IoT technologies, generating and collecting massive amounts of data from various dimensions through the Internet of Things, storing it in the cloud and at the edge, and then using big data analytics and more advanced forms of artificial intelligence to achieve the digitization and intelligent interconnection of everything. The ultimate goal of integrating IoT and AI technologies is to form an intelligent ecosystem within which interoperability and convergence are achieved between different intelligent terminal devices, different system platforms, and different application scenarios—a true integration of everything.

[0004] Currently, the industry's monitoring of gas fire extinguishing cylinder assemblies mainly relies on regular manual inspections and static testing of single parameters (such as pressure gauge readings), which has the following shortcomings:

[0005] Poor real-time performance: Manual inspections have long cycles, making it difficult to detect sudden leaks or pressure drops in a timely manner;

[0006] Insufficient intelligence: Lacks data fusion analysis and remote early warning capabilities, making it impossible to predict potential faults;

[0007] High maintenance costs: It relies on manual recording and periodic replacement, and lacks a precise maintenance strategy based on status.

[0008] Therefore, there is an urgent need for a terminal device that integrates dynamic monitoring, intelligent analysis, and remote control to achieve efficient management of the entire life cycle of gas fire extinguishing cylinder groups and facilitate the optimization and upgrading of fire protection systems.

[0009] Currently, the status detection of fire-fighting gas extinguishing equipment cylinder groups does not have the function of real-time detection and judgment. Pressure data needs to be fed back to the main system for judgment, which will lead to a slow response of the main system and may cause data delay. Moreover, the detection data may be distorted during transmission without processing. Utility Model Content

[0010] The purpose of this utility model is to address the above-mentioned problems by providing a dedicated data transmission line for AIot bottle group status detection, which facilitates the need for real-time detection and judgment, enables data transmission, reduces the pressure on the main system, avoids data generation and distortion of detection data, and facilitates dynamic monitoring and intelligent management of fire protection systems.

[0011] To achieve the above objectives, the technical solution adopted by this utility model is: a dedicated data transmission line for AIot bottle group status detection, including a main line using the RS485 protocol, and a round hole-shaped main line connector at the front end of the main line for plugging into the chassis. Multiple nodes are spaced apart on the main line, and each node is connected in parallel on the main line. Each node is arranged in series on the main line and protrudes from the main line in a T-shape. The tail end of the T-shape is connected to the status detection terminal for detecting gas cylinder groups through a connection cable interface for quick plugging.

[0012] Furthermore, the main line 2 consists of a multi-strand wire harness, with two wires being power lines and two being data transmission lines.

[0013] Furthermore, the nodes of the main line are electrically connected to the status detection terminal via a connection cable interface. The status detection terminal is equipped with a digital display screen and terminal buttons for setting and calling programs.

[0014] Furthermore, the status detection terminal is equipped with a pressure sensor for real-time gas detection, a detection board for reading pressure sensor data, and a processor board for judging the detection data. The final judged value is transmitted to the chassis system through data transmission.

[0015] Furthermore, the pressure sensor at the end of the status detection terminal is directly connected to the nozzle of the fire extinguishing gas cylinder to be detected via a threaded connection.

[0016] Furthermore, a branch line is separated perpendicularly from the main line at the node on the main line. The end of the branch line is provided with a connection wire pair interface, which is electrically quick-connected to the connection wire plug of the status detection terminal. The connection point also uses a 4-strand wire harness, of which 2 are power wires and 2 are data wires.

[0017] Furthermore, the main line is composed of multiple quick-connect segments, wherein a main line interface is provided at the right end of the T-shaped junction at the end of the main line, and a main line plug is provided at the front end of the corresponding segment for connection.

[0018] Furthermore, segments on the main line can be formed by a single node or by multiple nodes forming a segment for connection.

[0019] The beneficial effects of this utility model are as follows: A dedicated data transmission line for AIot bottle group status detection facilitates the need for real-time detection and judgment, enabling data transmission; reduces the pressure on the main system, avoids data generation, and prevents data distortion; and facilitates dynamic monitoring and intelligent management of the fire protection system.

[0020] It achieves real-time data acquisition and local judgment through modular design and edge computing; quick plug-and-play maintenance; and parallel monitoring of multiple bottle groups.

[0021] The main issues to be addressed are as follows:

[0022] Data transmission latency: Existing technologies mostly employ centralized data processing, resulting in slow system response;

[0023] Inconvenient connection: Traditional wired connections are fixed and difficult to maintain;

[0024] Insufficient intelligence: It lacks edge computing capabilities and relies on backend processing;

[0025] This enables intelligent management and facilitates dynamic monitoring of the fire protection system.

[0026] The system uses a detection board to read and display pressure sensor data. Then, a program on the connection board directly judges the pressure value, displaying or triggering an alarm. The judged value is transmitted to the fire protection system's backend via a transmission line. This allows for direct on-site confirmation of gas cylinders with abnormal pressure, while the fire protection system also detects the anomaly and facilitates management investigation. Furthermore, because the pressure judgment process occurs directly at the gas cylinder end, the pressure judgment requirement for the fire protection system is reduced, allowing for more efficient and streamlined operation of the backend system, thus achieving optimization and upgrades to the fire protection system.
