行业：仓储物流

Integrated solution for gas safety monitoring in warehousing and logistics

行业痛点

仓储物流是"危险品集中 + 货物种类多变 + 人员频繁进出"的复合风险场所：① **危化品仓库**：易燃液体（LEL）+ 有毒（H2S / HCN）+ 腐蚀（HCl / Cl2）+ 易爆（硝酸盐 / 氯酸盐）按 GB 17914-2013 分库存放，但多家化工企业共用园区仓库时管理失控；② **冷链物流**：氨制冷剂泄漏（爆炸 + 中毒）+ 干冰 CO2 缺氧 + 冷藏车厢密闭氧气消耗；③ **AGV / 锂电充电区**：动力电池热失控（H2 + CO + 烟雾，火灾迅速失控）；④ **危险品装卸**：码头 / 内河港 / 公路 / 铁路场站，频繁倒装风险高；⑤ **保税区 + 跨境物流**：海关监管 + 危化品申报 + 应急联动复杂。2015 年天津港爆炸的本质就是危化品仓储管理 + 气体监测缺位。监管层面 GB 17914 危化品仓库 + GB 50016 建筑防火 + 园区双控 + 应急管理局年度审查极严。

## Key Monitoring Nodes

### Hazardous Chemicals Warehouse (Classified According to GB 17914)

– **Class A warehouse** (flash point < 28℃, strong combustion): acetone / ether / methanol / benzene, etc. → LEL + PID (VOC PPB level) + infrared imaging - **Class B storage** (flash point: 28-60℃): diesel / heavy oil / alcohols → LEL + smoke detection - **Class C warehouse** (above 60℃ + flammable solids): sulfur / nitrates → LEL + temperature (preventing spontaneous combustion) - **Corrosive Chamber** (Acid and Alkali): HCl / sulfuric acid mist + Cl2 (bleach) + NH3 (ammonia) - **Highly Toxic Substance Warehouse** (double-person double-lock): dedicated probe for highly toxic substance leakage + video linkage + intrusion alarm ### Cold Chain Cold Storage - **Ammonia refrigeration room**: NH3 (range 0-1000 ppm, 10 ppm warning + 30 ppm emergency exhaust activation) + O2 + LEL - **Inside cold storage (-18℃ to -25℃)**: Probe specifically designed for low-temperature environments (regular probes become ineffective at -10℃) - **Refrigerated vehicle loading and unloading port**: CO2 + oxygen deficiency (dry ice transportation) ### AGV / Lithium Battery Charging Area (Emerging Risk) - **H2 (hydrogen)**: H2 will be released during the early stages of thermal runaway in power batteries (lithium iron phosphate / ternary), and the sensor sensitivity is set at 0.01 ppm to trigger an alarm - **CO**: By-product of battery electrolyte decomposition - **Smoke**: Early indication of a fire hazard - **Infrared thermal imaging**: Battery temperature field inversion, with normal temperature < 35℃ and hot spots > 50℃ automatically triggering an alarm, initiating directional measures, and isolating the area
– **Emergency linkage**: Detection of thermal runaway symptoms → Initiation of targeted fire suppression + emergency ventilation + area isolation + notification to operators

### Hazardous Materials Loading and Unloading Station (Road / Rail / Wharf)

– Fixed LEL + H2S + Grounding Wire Status
– Crew portable 4-in-1
– Flow rate / concentration measurement (oil and gas recovery efficiency ≥ 95%)
– Video linkage violation recognition (no PPE handling / no electrostatic discharge wristband worn)

## Key Technical Indicators

– Explosion-proof: Ex d IIB T4 (Class A warehouse) / Ex d IIC T6 (H2-containing lithium battery charging area)
– Protection: IP65 (IP66 in cold storage + low temperature tolerance)
– Range: H2 0.01-100% LEL (ppb sensitivity required for lithium battery scenarios)
– Operating temperature: -30℃ ~ +60℃ (cold storage + outdoor warehouse)
– Communication: 4G + LoRa (warehouses usually lack WiFi coverage)
– Battery life: Remote hazardous chemical warehouses require a battery-powered version with a 5-year lifespan

## Implementation Key Points

1. **Hazardous Chemicals Warehouse Level Response**: Low alarm → warehouse manager checks; high alarm → initiates spraying/ventilation + notifies supervisor; ultra-high alarm → emergency response + evacuation + 119 linkage
2. **AGV Charging Thermal Runaway**: Detection of H2 + abnormal temperature → immediate shut-off of the charging station + isolation + initiation of targeted fire suppression
3. **Cold chain ammonia leakage**: NH3 is easily soluble in water. In emergency situations, use water spray for dilution, initiate emergency ventilation, and shut down the compressor
4. **Customs + Emergency Management Bureau Compliance**: All gas monitoring data in cross-border logistics scenarios can be integrated with the customs declaration system + Emergency Management Bureau
5. **Multi-customer shared warehouse**: Each shipper has an independent account + data isolation to prevent the leakage of trade secrets
