Description

Technical Field

[0001] This application relates to the field of shipbuilding technology, and in particular to a mobile gas monitoring and wireless self-organizing network system, method and electronic equipment. Background Technology

[0002] Ro-Ro ships are primarily used for long-distance vehicle transport. They feature multi-level open car decks, dense cabins, and a large amount of confined workspace. The construction process is complex, involving multiple overlapping procedures such as dockside section assembly, outfitting, painting, and mechanical and electrical equipment commissioning. During the core construction phases of dockside outfitting and wharf commissioning, the overall hull structure is not yet fully enclosed and fixed pipelines and equipment are not yet installed. However, various high-risk construction operations are already underway simultaneously in areas such as multi-level car decks, engine rooms, steering gear rooms, and ballast tanks.

[0003] The construction site presents multiple gas safety hazards, including: welding operations continuously generate toxic fumes such as carbon monoxide and nitrogen oxides; paint and thinner volatilize and produce combustible organic gases during painting operations; fuel vapor and refrigerant leaks are likely to occur during the commissioning of fuel pipelines and refrigeration equipment; and various enclosed and semi-enclosed compartments have poor ventilation, which can easily lead to gas accumulation and oxygen deficiency, and may cause safety accidents such as poisoning, explosion, and suffocation.

[0004] Traditional gas monitoring technologies are ill-suited to the unique working conditions of shipbuilding and suffer from numerous technical limitations: Fixed detectors are not suitable: During the construction phase, the cabin structure and work area change frequently, power supply and signal lines cannot be pre-embedded, and fixed equipment is easily damaged by collisions during construction operations, making it completely unsuitable for installation and use. The management and control of portable monitoring devices is lagging behind: manual handheld portable detectors can only achieve local alarms on site and cannot transmit data remotely. Safety management personnel cannot keep track of the gas status at multiple points on the entire ship in real time, making it difficult to supervise the entire area. Poor wireless transmission reliability: During construction, the large number of metal bulkheads and decks created a strong electromagnetic shielding environment. Conventional Wi-Fi and Bluetooth communication technologies suffered severe signal attenuation and weak penetration. There were many signal blind spots deep inside the compartments, and data packet loss and disconnection problems occurred frequently. Unable to meet the needs of temporary dynamic monitoring: The construction of high-risk operation sites is dynamically adjusted daily. Traditional monitoring solutions are rigid in deployment and inconvenient to relocate, and cannot meet the needs of temporary monitoring that can be quickly deployed and flexibly reused. Summary of the Invention

The intelligent self-organizing network repeater is temporarily deployed between deck levels and in signal blind spots in cabins of the ship. It communicates wirelessly with the portable composite gas detector to receive and relay monitoring data and autonomously build a dynamic network transmission network. The monitoring host is located in the dockside monitoring room or the temporary safety area of ​​the ship, and is used to collect all monitoring data transmitted via relay and upload it to the cloud server through the shipyard network or cellular network.

The terms "first," "second," etc., in this application are used to distinguish similar objects and are not used to describe a specific order or sequence.

[0021] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 , Figure 2 As shown, an embodiment of this application provides a mobile gas monitoring and wireless self-organizing network system, including: at least one mobile composite gas detector, at least one intelligent self-organizing network repeater, a monitoring host, and a cloud server. The portable composite gas detector is deployed at temporary high-risk work sites during ship construction to collect monitoring data in real time. The monitoring data includes the concentration of various gases on site, equipment power consumption, and location status data. The back of the portable composite gas detector is equipped with a permanent magnet for adsorbing and fixing onto the surface of the ship's steel structure. The intelligent self-organizing network repeater is temporarily deployed between deck levels and in signal blind spots in cabins of the ship. It communicates wirelessly with the portable composite gas detector to receive and relay monitoring data and autonomously build a dynamic network transmission network. The monitoring host is located in the dockside monitoring room or the temporary safety area of ​​the ship, and is used to collect all monitoring data transmitted via relay and upload it to the cloud server through the shipyard network or cellular network. The cloud server is used to receive, store, and analyze monitoring data throughout the entire cycle, and to push alarm information when there are abnormalities in the monitoring data.

[0023] In this embodiment, the housing of the portable composite gas detector is made of explosion-proof and flameproof material. The portable composite gas detector is equipped with a battery module and a wireless data transmission module. The battery module includes a rechargeable lithium battery and a power monitoring module. The wireless data transmission module includes a long-range (LoRa) wireless transmission module, which has the ability to penetrate metal obstacles and diffract in space, and is suitable for the shielded environment of metal cabins on ships.

[0024] The rechargeable lithium battery, combined with an ultra-low power consumption circuit design, provides a continuous standby time of ≥10 days, covering long-cycle construction processes such as segmented construction and batch painting, solving the problem of inconvenient on-site power supply. The power monitoring module features real-time power display and remote low-power alarm functions, actively uploading alarm signals to the monitoring host when the power is insufficient, prompting staff to perform timely maintenance. The long-range (LoRa) wireless transmission module possesses excellent metal penetration and spatial diffraction capabilities, effectively reducing signal attenuation caused by steel structure shielding, and is suitable for complex cabin transmission environments.

[0025] In this embodiment, the portable composite gas detector integrates a displacement sensing module, which is used to trigger local and remote anti-theft alarms when the device is moved abnormally. When the device is moved or disassembled abnormally, a local audible and visual alarm and a remote alarm are triggered simultaneously to prevent the device from being lost during construction.

[0026] In this embodiment, the intelligent self-organizing network repeater adopts a magnetic installation structure and is equipped with a power supply battery. Multiple intelligent self-organizing network repeaters can automatically handshake to form a network and establish a transmission route. When a single intelligent self-organizing network repeater goes offline, the network is automatically reconstructed to ensure uninterrupted data transmission.

[0027] In this embodiment, the monitoring host is an industrial-grade tablet structure equipped with a high-definition touch screen and a built-in 4G / 5G and Wi-Fi dual-mode communication module, which supports synchronous monitoring and management of data from multiple workstations and multiple areas of detectors.

[0028] The aforementioned portable gas monitoring and wireless self-organizing network system consists of a magnetically attached portable composite gas detector, a magnetically attached intelligent self-organizing network repeater, a shore-based monitoring host, and a cloud server. The detector is attached to temporary high-risk locations on the ship to collect gas, electricity, and location monitoring data. The repeater is deployed in signal blind spots to autonomously build a dynamic network to relay data, solving the signal disconnection and packet loss problems caused by the ship's metal shielding. The monitoring host aggregates the data and uploads it to the cloud via the shipyard or cellular network. The cloud stores and analyzes the full-cycle data and pushes alarms for anomalies. The equipment requires no wiring, can be quickly moved and reused, adapts to dynamic operation points during ship construction, and achieves remote real-time centralized monitoring of multiple points, eliminating the shortcomings of traditional equipment such as rigid deployment, unstable transmission, local alarm only, and lagging overall control.

[0029] like Figure 2 , Figure 3 , Figure 4 As shown, this application also provides a mobile gas monitoring and wireless self-organizing network method, including: Step S1: Based on the ship construction plan, the painting section, welding station, and equipment debugging room are selected as high-risk work areas with gas risks. Step S2: Deploy the portable composite gas detector to the monitoring points in each high-risk work area using a magnetic attraction method; Step S3: Based on the ship's steel structure layout and signal test results, identify weak signal areas between deck levels and deep within cabins, and deploy intelligent self-organizing network repeaters in the weak signal areas; Step S4: The detector collects monitoring data in real time and transmits it to the nearest intelligent self-organizing network repeater via long-distance wireless transmission. The monitoring data includes the concentration of various gases on site, equipment power and location status data. Step S5: Each repeater relays the monitoring data by autonomously building a dynamic networking transmission network, and aggregates all the monitoring data to the monitoring host on the shore or in the temporary safe zone. Step S6: The monitoring host uploads the monitoring data to the cloud server in real time via a cellular network or the shipyard's local area network. Step S7: The cloud server analyzes and compares the monitoring data, and pushes alarm information when there is data anomaly in the monitoring data.

[0030] Data anomalies include excessive gas levels, equipment power levels below preset limits, and equipment theft or relocation. Alarm information can be sent via on-site audio and visual alerts, SMS messages, and mobile app notifications.

[0031] In this embodiment, the mobile gas monitoring and wireless self-organizing network method further includes: The cloud server stores monitoring data and alarm records throughout the entire construction cycle.

[0032] In this embodiment, the mobile gas monitoring and wireless self-organizing network method further includes: According to the construction progress, when the current construction process is completed or the next construction process is started, the signal transmission strength of the portable composite gas detectors set at the monitoring points in each risk operation area is detected, and the deployment position of the portable composite gas detectors and / or the intelligent self-organizing network repeaters is adjusted according to the signal transmission strength of the portable composite gas detectors.

[0033] In this embodiment, the mobile gas monitoring and wireless self-organizing network method further includes: After deploying intelligent self-organizing network repeaters in the signal-weak areas, the signal transmission strength of the portable composite gas detectors at the monitoring points set up in each risk operation area is detected, and the deployment positions of the portable composite gas detectors and / or the intelligent self-organizing network repeaters are adjusted according to the signal transmission strength of the portable composite gas detectors.

[0034] In the aforementioned mobile gas monitoring and wireless self-organizing network method, high-risk work areas such as painting, welding, and equipment debugging are first delineated according to the shipbuilding construction plan. Mobile composite gas detectors are deployed using magnetic attraction to collect monitoring data on gas concentration, equipment power, and location status. Then, combined with the signal test results of the ship's steel structure, intelligent self-organizing network repeaters are deployed in areas with weak signals. The repeaters autonomously construct a dynamic network to complete data relay transmission. All data is uniformly aggregated to the monitoring host and then uploaded to the cloud server via the shipyard's local area network or cellular network. The cloud stores and analyzes the data throughout the entire lifecycle and pushes alarms when data is abnormal. The detector signal strength is detected before and after construction, and the deployment positions of the detectors and repeaters are flexibly adjusted to adapt to the dynamic changes in ship construction processes. The self-organizing network repeaters overcome the signal blind spots and data interruption problems caused by the metal shielding of the ship's hull. The magnetic deployment enables rapid and flexible adjustment of monitoring points. The cloud enables traceability of monitoring data for the entire process and remote unified alarm supervision. This solves the technical defects of traditional monitoring, such as fixed deployment, unstable transmission, inability to remotely control the entire area in real time, and insufficient monitoring coverage after process changes.

[0035] The beneficial effects of this invention are as follows: Rapid deployment, high mobility, and high reusability: All equipment can be installed without tools using magnetic suction, and can be deployed and moved in minutes. It perfectly adapts to the temporary monitoring needs of dynamic changes in the construction work surface. The equipment can be reused across processes and regions, greatly reducing monitoring costs. Overcoming transmission bottlenecks in complex environments: By adopting LoRa communication + self-organizing network relay technology, the electromagnetic shielding problem of multi-layered metal bulkheads on ships is specifically solved, completely eliminating signal blind spots deep in the compartments and achieving stable and continuous transmission of monitoring data; Highly adaptable to special construction conditions: Ultra-low power consumption and long battery life design to adapt to insufficient power supply on site, dual explosion-proof structure to meet the safety requirements of high-risk operations, anti-theft alarm function to eliminate the risk of loss of open construction equipment, and extremely strong scene adaptability. Enhance safety management efficiency: Enable remote centralized monitoring of all dispersed locations on the ship, reduce the frequency of personnel inspections in confined spaces, reduce the risk of personal exposure, and significantly improve the intelligence and precision of shipbuilding safety management; Full lifecycle data traceability: The cloud automatically stores monitoring data and alarm records throughout the entire construction lifecycle, providing reliable data support for accident tracing, work approval, and safety system optimization.

[0036] The following explanation uses the gas monitoring application during the construction phase of a large PCTC roll-on / roll-off ship as an example.

[0037] Construction Scenario Background: A shipyard is constructing a 6200-vehicle PCTC roll-on / roll-off (Ro-Ro) vessel. The hull sections have been assembled, and the ship is currently in the dockside outfitting, painting, and electromechanical equipment commissioning phase. The key construction areas are the lower car decks of decks 5 and 7, and the engine room area. Epoxy painting is being carried out on decks 5 and 7, posing a risk of flammable organic gas volatilization. Simultaneously, pipeline welding, fuel and refrigeration equipment commissioning are being conducted in the engine room, posing a risk of toxic fumes and media leaks. These areas are highly enclosed, poorly ventilated, and the multi-layered steel structure creates severe signal shielding, rendering conventional monitoring solutions inadequate for construction safety requirements.

[0038] The on-site deployment of the system includes: detector deployment, repeater deployment, and monitoring host deployment.

[0039] Detector Deployment: Composite gas detectors are selected, supporting the detection of combustible gases (EX) and carbon monoxide (CO). One unit is deployed at each end of the painting area on deck 5, one unit is deployed in the poorly ventilated area on the bottom of deck 7, and one unit is deployed at the welding and commissioning station in the engine room. All devices are attached to the steel bulkhead via permanent magnets on their backs, allowing for tool-free installation with a total deployment time of 10 minutes.

[0040] Repeater Deployment: To address the severe signal shielding issue on the lower deck of Deck 7, one intelligent self-organizing repeater was deployed at the stairwell entrance on Deck 5 and the mid-passage on Deck 3. After magnetic attachment, the devices automatically power on and form a network, completing route optimization within 2 minutes and establishing a transmission channel connecting the lower deck compartments to the shore base.

[0041] Monitoring host deployment: The industrial-grade monitoring host is deployed in the dock-based monitoring room and connected to the shipyard's fiber optic local area network to realize real-time data display, storage and cloud upload.

[0042] The on-site test results include: transmission performance test, gas alarm test, shift multiplexing test, and long-term operation test.

[0043] Transmission performance test: Without repeaters, the data packet loss rate of the bottom detector on deck 7 was 35%, and the signal was frequently interrupted; after enabling the self-organizing network repeaters, the data from all points on the ship was uploaded stably, the packet loss rate dropped to 0%, the alarm transmission delay was ≤3 seconds, and the transmission reliability was greatly improved.

[0044] Gas alarm test: Using standard gas to simulate the scenario of excessive gas in the coating area, the T90 detector has a response time of ≤20 seconds, and simultaneously triggers local audible and visual alarms, monitoring room pop-up alarms, and mobile phone SMS alarms, with timely and accurate alarm response.

[0045] Relocation and reuse test: After moving the nacelle detector to the new work point in the steering gear room and reattaching and fixing it, the system automatically recognizes the device and resumes data upload within 1 minute. No manual configuration is required, which is suitable for dynamic operation requirements.

[0046] Long-term operation test: The system ran continuously and stably for 15 days, covering the entire process of painting, welding, and equipment debugging. The equipment can last up to 12 days on a single charge, and the low battery alarm is timely and effective; the equipment was accidentally moved during construction, triggering one anti-theft alarm, which promptly avoided the risk of equipment loss; the system accurately detected two instances of short-term gas exceeding the standard in the painting area, promptly alerting and guiding on-site ventilation, successfully avoiding safety accidents.

[0047] This embodiment fully verifies that the system of the present invention can be perfectly adapted to the working conditions of multiple overlapping processes, complex environment, and variable locations in the construction of ro-ro ships. It effectively solves the technical problems of rigid deployment, unstable transmission, and lagging control of traditional monitoring solutions. The system has extremely high stability and practicality, and can realize intelligent monitoring of gas safety throughout the entire construction cycle of ro-ro ships. It has extremely high engineering application and industry promotion value.
