实时监测环境温度变化，及时发现火灾隐患 Real-time monitoring of environmental temperature changes, timely detection of fire hazards
火灾隐患的滋生往往始于细微的温度异常，从局部过热、阴燃到明火蔓延，短短几分钟即可造成不可挽回的人员伤亡与财产损失。对于工业厂区、仓储物流、电力设施、市政管廊等各类场景而言，传统火灾监测手段要么存在监测盲区，要么响应滞后，难以实现“防患于未然”的核心需求。安电安通（无锡）技术有限公司立足安全监测领域，依托自身在电气设备、智能监测领域的技术积淀，推出基于DTS分布式光纤测温技术的火灾监测解决方案，以实时、精准、全面的温度监测能力，捕捉每一处温度异常，提前预警火灾隐患，为各类场景筑牢安全防线。 The fire hazards often begins with subtle temperature anomalies, from local overheating and smoldering to open flame spread, which can cause irreparable casualties and property losses in just a few minutes. For various scenarios such as industrial plants, warehousing and logistics, power facilities, and municipal utility tunnels, traditional fire monitoring methods either have monitoring blind spots or lag in response, making it difficult to achieve the core requirement of "prevention before occurrence." ADAT Power (Wuxi) Technology Co., Ltd., based in the safety monitoring field, leverages its technical accumulation in electrical equipment and intelligent monitoring to launch a fire detection solution based on DTS distributed fiber optic temperature measurement technology. With real-time, precise, and comprehensive temperature monitoring capabilities, it captures every temperature anomaly, provides early warning of fire hazards, and builds a solid safety defense line for various scenarios.
核心技术：DTS分布式光纤测温原理，解锁精准监测新方式 Core Technology: DTS Distributed Fiber Optic Temperature Sensing Principle, Unlocking New Ways of Precise Monitoring
安电安通火灾监测产品的核心竞争力，源于DTS（Distributed Temperature Sensing）分布式光纤测温技术的深度应用。与传统点式测温、红外测温等方式不同，DTS分布式光纤测温系统以光纤为传感介质，兼具“传感+传输”双重功能，无需额外部署传感器，即可实现全区域无盲区温度监测，其核心原理基于光纤中的自发拉曼散射效应与光时域反射（OTDR）技术，实现温度与位置的同步精准解调。 The core competitiveness of ADAT Power's fire detection products stems from the in-depth application of DTS (Distributed Temperature Sensing) distributed fiber optic temperature measurement technology. Different from traditional point temperature measurement and infrared temperature measurement methods, the DTS distributed fiber optic temperature measurement system uses optical fiber as the sensing medium, with both "sensing + transmission" functions, eliminating the need for additional sensors and enabling full-area blind-spot-free temperature monitoring. Its core principle is based on the spontaneous Raman scattering effect in optical fibers and optical time domain reflectometry (OTDR) technology, achieving synchronous and precise demodulation of temperature and position.
当系统发射的激光脉冲在光纤中传输时，会与光纤分子发生非弹性碰撞，产生拉曼散射光，这种散射光包含两种关键成分：斯托克斯光与反斯托克斯光。其中，斯托克斯光的强度对温度变化不敏感，可作为稳定的参考基准；反斯托克斯光的强度则与环境温度呈显著的指数关系，温度越高，反斯托克斯光强度越强，反之则急剧衰减。通过精准检测两种散射光的强度比值，结合预设的标定公式，即可精确解调出光纤沿线各点的绝对温度，有效规避光源功率波动、光纤损耗等因素对测温精度的干扰。 When the system emits laser pulses that travel through the optical fiber, they collide inelastically with fiber molecules, producing Raman scattered light. This scattered light contains two key components: Stokes light and anti-Stokes light. Stokes light intensity is insensitive to temperature changes and can serve as a stable reference baseline, while anti-Stokes light intensity has a significant exponential relationship with ambient temperature—higher temperatures result in stronger anti-Stokes light intensity, and vice versa. By precisely detecting the intensity ratio of these two scattered lights and combining it with preset calibration formulas, the absolute temperature at each point along the fiber can be accurately demodulated, effectively avoiding interference from factors such as light source power fluctuations and fiber loss on temperature measurement accuracy.
同时，借助OTDR技术，系统可记录激光脉冲发射至接收背向散射光的时间差，结合光在光纤中的传播速度与光纤有效折射率，精准计算出温度异常点的具体位置，定位精度可达≤1m，实现“哪里温度异常，就精准定位哪里”的效果。这种“分布式”监测模式，打破了传统测温技术的空间局限，单根光纤即可覆盖数公里监测范围，完美适配大型工业场景、长距离管廊等复杂监测需求，这也是安电安通火灾监测产品区别于传统设备的核心优势所在。 Simultaneously, using OTDR technology, the system records the time difference between laser pulse emission and backscattered light reception. Combined with the speed of light in the fiber and the fiber's effective refractive index, it precisely calculates the specific location of temperature anomalies, with a positioning accuracy of ≤1m, achieving the effect of "precisely locating where temperature anomalies occur." This "distributed" monitoring mode breaks the spatial limitations of traditional temperature measurement technology—a single fiber can cover monitoring ranges of several kilometers, perfectly adapting to complex monitoring needs in large industrial scenarios, long-distance utility tunnels, and other settings. This is the core advantage that differentiates ADAT Power's fire detection products from traditional equipment.
此外，DTS分布式光纤测温技术具备本质防爆、抗强电磁干扰、防雷击、耐高低温的特性，可在潮湿、高温、高干扰、易燃易爆等恶劣环境中稳定运行，使用寿命长达数十年，大幅降低后期运维成本，这与安电安通“可靠、高效、节能”的产品研发理念高度契合，也使其产品能够广泛适配电力、石化、仓储、市政等多领域的安全监测需求。 Furthermore, DTS distributed fiber optic temperature measurement technology features intrinsic explosion protection, strong electromagnetic interference resistance, lightning protection, and high and low temperature resistance. It can operate stably in harsh environments such as humidity, high temperatures, high interference, and易燃易爆 areas, with a service life of decades, significantly reducing long-term operation and maintenance costs. This highly aligns with ADAT Power's product development philosophy of "reliable, efficient, and energy-saving," enabling its products to be widely applicable to safety monitoring needs in multiple fields such as power, petrochemical, warehousing, and municipal utilities.

This truly实现 the goal of "early detection, early warning, early disposal," curbing fire accidents at their source.
1.工业厂区监测 1. Industrial Plant Monitoring
工业厂区内的生产设备、电缆线路、易燃易爆物料存储区等，是火灾隐患的高发区域。安电安通火灾监测系统可将感温光纤沿设备管线、电缆桥架、物料仓库墙面及地面敷设，实时监测沿线温度变化。当设备运行过载、电缆接头老化过热，或物料堆积发生阴燃，导致局部温度超出预设阈值时，系统会立即发出声光报警，同步在监控终端显示异常点的精准位置、实时温度及温度变化曲线，提醒工作人员及时排查隐患，避免设备损坏、火灾蔓延等事故。尤其适用于石化储罐区、化工生产车间等高危场景，其本质防爆特性可有效规避监测设备自身引发的安全风险，保障生产安全。 Production equipment, cable lines, and flammable and explosive material storage areas in industrial plants are high-risk areas for fire hazards. The ADAT Power fire detection system can lay temperature-sensitive optical fibers along equipment pipelines, cable trays, warehouse walls, and floors to real-time monitor temperature changes along the route. When equipment is overloaded, cable joints overheat due to aging, or materials smolder due to accumulation, causing local temperatures to exceed preset thresholds, the system immediately issues声光 alarms, simultaneously displaying the precise location of anomalies, real-time temperatures, and temperature change curves on monitoring terminals, reminding staff to promptly investigate hidden dangers and avoid accidents such as equipment damage and fire spread. It is particularly suitable for high-risk scenarios such as petrochemical storage tank areas and chemical production workshops, where its intrinsic explosion-proof properties can effectively avoid safety risks caused by the monitoring equipment itself, ensuring production safety.
2.电力设施监测 2. Power Facility Monitoring
变电站、电缆沟、输电线路等电力设施，长期处于高负荷运行状态，电缆老化、接头松动等问题易引发局部过热，进而诱发火灾，造成大面积停电。安电安通火灾监测产品可针对电力场景定制部署，将感温光纤紧贴电缆敷设，或在电缆沟、变电站机房内分布式布置，实时监测电缆及设备的温度分布。系统可预设多级温度阈值，当温度达到预警阈值时，发出初级报警，提醒运维人员排查；当温度接近危险阈值时，立即触发高级报警，并联动应急处置设备，切断相关线路电源，最大限度降低火灾损失。实践证明，该系统可实现测温精度<±1℃，稳定运行时长超6年，为电力设施安全运维提供可靠保障。 Power facilities such as substations, cable trenches, and transmission lines operate under high load for long periods. Issues such as cable aging and loose joints can easily cause local overheating, leading to fires and large-scale power outages. ADAT Power's fire detection products can be custom-deployed for power scenarios, laying temperature-sensitive optical fibers close to cables or distributed in cable trenches and substation equipment rooms to real-time monitor temperature distribution of cables and equipment. The system can preset multiple temperature thresholds: when the temperature reaches the warning threshold, it issues a primary alarm to remind operation and maintenance personnel to investigate; when the temperature approaches the danger threshold, it immediately triggers a high-level alarm and links to emergency disposal equipment to cut off power to relevant lines, minimizing fire damage. Practice has proven that the system can achieve temperature measurement accuracy <±1℃ and stable operation for over 6 years, providing reliable保障 for the safe operation and maintenance of power facilities.
3.仓储物流监测 3. Warehousing and Logistics Monitoring
仓储物流中心存储的货物种类繁多，部分货物（如纺织品、化工原料、纸质品）属于易燃物品，一旦发生阴燃，隐蔽性强、蔓延速度快，传统监测手段难以及时发现。安电安通火灾监测系统可将感温光纤沿仓储货架、通道、货物堆放区域敷设，实现全域无盲区监测。当货物因堆放过密、通风不良或外部热源影响导致温度异常升高时，系统可快速捕捉到温度变化，及时发出预警，同时精准定位异常区域，方便工作人员快速找到隐患点，采取通风、转移货物等处置措施，避免火灾事故发生。 Warehousing and logistics centers store a wide variety of goods, some of which (such as textiles, chemical raw materials, and paper products) are flammable. Once smoldering occurs, it is highly concealed and spreads quickly, making it difficult for traditional monitoring methods to detect in time. The ADAT Power fire detection system can lay temperature-sensitive optical fibers along storage shelves, aisles, and goods stacking areas to achieve full-area blind-spot-free monitoring. When goods experience abnormal temperature rises due to overcrowding, poor ventilation, or external heat sources, the system can quickly capture temperature changes, issue timely warnings, and precisely locate abnormal areas, making it easy for staff to quickly find hidden danger points and take disposal measures such as ventilation and goods transfer to avoid fire accidents.
4.市政管廊监测 4. Municipal Utility Tunnel Monitoring
城市地下综合管廊内铺设着电力、通信、燃气、给排水等各类管线，空间密闭、环境复杂，一旦某类管线发生泄漏、过热，极易引发火灾或爆炸事故，且救援难度大。安电安通火灾监测系统可将感温光纤沿管廊内壁、管线表面敷设，实时监测管廊内及各管线的温度变化，尤其针对燃气管道、电力电缆等高危管线，可实现24小时不间断监测。当管线出现温度异常或泄漏引发的温度波动时，系统立即报警，精准定位隐患位置，为管廊运维人员提供及时的预警信息，保障城市基础设施安全运行。 Urban underground integrated utility tunnels house various pipelines such as power, communication, gas, and water supply and drainage. The enclosed space and complex environment mean that once a pipeline leaks or overheats, it can easily trigger fires or explosions, with high rescue difficulty. The ADAT Power fire detection system can lay temperature-sensitive optical fibers along tunnel inner walls and pipeline surfaces to real-time monitor temperature changes in the tunnel and along each pipeline. Particularly for high-risk pipelines such as gas pipelines and power cables, it can achieve 24-hour uninterrupted monitoring. When pipelines experience temperature anomalies or temperature fluctuations caused by leaks, the system immediately alarms, precisely locates hidden danger positions, and provides timely warning information for tunnel operation and maintenance personnel, ensuring the safe operation of urban infrastructure.
