In today's era of booming global trade, the vast oceans have become vital links connecting the world, with ocean-going cargo ships traversing them like steel behemoths, shouldering the heavy responsibility of transporting goods. However, the potential risk of ammonia leaks looms constantly during vessel operations. As a highly irritating and corrosive gas, ammonia leaks not only pose severe threats to crew safety but can also trigger major incidents like fires and explosions. These incidents inflict immeasurable damage on navigation safety and marine ecosystems.

　　Particularly as international maritime safety regulations grow increasingly stringent, shipping companies face ever-stricter demands for vessel safety management. Against this backdrop, a prominent shipping enterprise in the industry deeply recognized the critical importance of ammonia monitoring for safe vessel operations. To equip its ocean-going cargo ships with an advanced and reliable ammonia monitoring system, the company initiated comprehensive market research and technical evaluations. After rigorous screening and comparison, Yiyuntian Eranntex online low-power ammonia monitoring system stood out due to its unique advantages, ultimately emerging as the unparalleled choice for ensuring vessel safety.

　　I. Solution Background

　　Requirement: Deployment of a 24/7 uninterrupted ammonia safety monitoring system for large vessels

　　Client Profile: A shipping company requiring a wireless, self-organizing, online ammonia concentration monitoring system for its ocean-going cargo vessels. The system must be wiring-free, feature extended battery life, and comply with international maritime safety regulations while meeting practical operational demands.

　　Core Challenges:

　　(1) No charging facilities available onboard except in the bridge. Equipment must have extended battery life, lasting ≥10 days.

　　(2) Complex vessel structure requires signal penetration through multiple deck layers to achieve seamless coverage throughout the ship.

　　(3) 24/7 uninterrupted monitoring and data transmission demand exceptional device endurance and network stability.

　　(4) Installation and maintenance must be straightforward, without impacting the vessel's structural integrity or operational functions.

　　II. Solution: Customized Low-Power Magnetic Self-Organizing Mesh System

　　III. System Configuration List (Core Equipment)

　　(1) Smart Self-Organizing Network Slave (Detector) × N units

　　Model: MIC-600-L

　　Key Features: Magnetic mounting, low-power motherboard, rechargeable battery, 255 LORA MESH terminal modules.

　　Function: Responsible for ammonia concentration detection and data upload, also serves as a network repeater.

　　Battery Life: ≥10 days (tested at approximately 13 days).

　　(2) Monitoring Host (Master Station) × 1 unit

　　Model: BTYQ-PTM600-S-YP-NH3

　　Key Features: Capacitive touchscreen, ≥45 detector interfaces, 255 LORA MESH gateway module, built-in battery.

　　Function: Data aggregation, real-time display, alarm triggering upon threshold exceedance. Installed in the cab, requires periodic charging (15-20 hours standby).

　　(3) Monitoring Host (Receiving End) × 1 unit

　　Model: BTYQ-PTM600-S-YP-NH3-2

　　Key Features: Receives host data, built-in battery.

　　Function: Provides redundant display in locations such as the engine room control center to enhance system reliability.

　　IV. Project Value and Customer Benefits

　　Safety Compliance: Enables 24/7 real-time online monitoring and alarm for ammonia concentrations in critical ship areas, significantly enhancing vessel safety standards while meeting and exceeding regulatory requirements.

　　Rapid Deployment: Magnetic mounting and wireless networking allow full system deployment during port layovers without disrupting schedules, with minimal installation costs.

　　Simple Operation & Maintenance: Local display with automatic startup upon power-on. Automatically displays gas concentration data and triggers alarms when concentrations exceed thresholds, requiring no routine maintenance.

　　Charging Duration: Fully charges in 8-10 hours, utilizing overnight downtime for charging.

　　Flexible & Reliable: Self-organizing network features strong anti-interference capabilities and self-healing properties. Detector quantity and placement can be flexibly adjusted based on actual vessel types, ensuring strong system scalability.

　　V. Experience Summary and Recommendations for Future Projects

　　(1) Defining requirements is critical: Clearly distinguish between “continuous monitoring” and “intermittent detection” regarding significant differences in power consumption and battery life. Communicate this distinction to clients (in this case, the client required 24/7 continuous monitoring mode with approximately 13 days of battery life).

　　(2) Host Monitoring with Zero Blind Spots: The host device displays real-time battery levels for each ammonia detector, enabling timely charging arrangements. Sleep mode conserves daily power consumption. Functions include checking device online status and viewing real-time gas concentration data, ensuring comprehensive monitoring coverage.

　　(3) On-site commissioning is essential: Wireless signals are significantly affected by vessel structures. Post-boarding signal testing is mandatory to determine the final number and placement of repeaters, ensuring full coverage. The solution must be flexible and adjustable.

　　(4) Training and System Safeguards: Prior to formal deployment, all field personnel must undergo mandatory training. An emergency response mechanism must be established to ensure personnel and site safety. In emergencies, the contingency plan must be activated immediately to promptly eliminate safety hazards, safeguarding personnel and property.

　　Conclusion: This project successfully validated the high feasibility of the innovative model—“low-power sensors + LORA MESH self-organizing network + magnetic installation + long endurance”—in complex marine environments. It provides a reliable, economical, and easily scalable standardized solution for similar shipboard gas monitoring projects.
