消防储能行业如何利用CAN转光纤？
1.BMS与消防控制器高压隔离通信：储能电池簇为高压直流环境，BMS与消防控制器直接CAN连接易产生地环路、电磁干扰，引发信号失真或短路。CAN转光纤实现2500V电气隔离，阻断高低压电位差，免疫EMI干扰，确保BMS电芯温度、电压数据与消防报警指令稳定传输，避免误报漏报。
1. High voltage isolation communication between BMS and fire controller: The energy storage battery cluster is in a high-voltage DC environment, and direct CAN connection between BMS and fire controller can easily generate ground loops and electromagnetic interference, causing signal distortion or short circuits. CAN to fiber optic achieves 2500V electrical isolation, blocking high and low voltage potential differences, immune to EMI interference, ensuring stable transmission of BMS cell temperature and voltage data and fire alarm commands, and avoiding false alarms and omissions.
2.大型储能电站跨舱消防组网：百兆瓦级电站由数十个电池舱组成，舱间距常超500米，传统CAN总线信号衰减严重。CAN转光纤将通信距离延伸至单模20km+，以星型/手拉手拓扑连接各舱消防分机与站级消防主机，实现全电站火情数据实时汇聚，保障灭火装置远程触发指令毫秒级送达。
2. Cross compartment fire protection network for large-scale energy storage power stations: A 100MW power station consists of dozens of battery compartments, with a spacing of over 500 meters between compartments, and traditional CAN bus signals suffer from severe attenuation. CAN to fiber optic extends the communication distance to single-mode 20km+, connecting each cabin fire extension and station level fire host in a star/hand in hand topology, achieving real-time aggregation of fire data for the entire power station and ensuring remote triggering instructions for fire extinguishing devices are delivered in milliseconds.
3.防爆区域消防信号传输：储能电站电池舱、电解液存储区属防爆场景，金属电缆易产生电火花。CAN转光纤采用无金属光纤介质，无电火花风险，适配防爆认证要求；同时耐腐蚀、抗潮湿，可在含VOC、H₂等可燃气体的恶劣环境中，稳定传输烟雾、气体浓度探测器的CAN数据，实现早期火情预警。
3. Fire signal transmission in explosion-proof areas: The battery compartment and electrolyte storage area of the energy storage power station belong to explosion-proof scenarios, and metal cables are prone to generating electrical sparks. CAN to fiber optic adopts non-metallic fiber optic medium, with no risk of electrical sparks, and is compatible with explosion-proof certification requirements; Simultaneously corrosion-resistant and moisture resistant, it can stably transmit CAN data of smoke and gas concentration detectors in harsh environments containing flammable gases such as VOCs and H ₂, achieving early fire warning.
4.消防系统环网冗余备份：采用“CAN+光纤”双通道冗余设计，构建光纤环网。正常工况下CAN总线传输数据，光纤作为备用链路；当火灾熔断电缆或单点链路故障时，光纤环网自动绕行，确保消防主机与灭火装置、应急排风系统的通信零中断，满足储能消防“零误动、零漏动”的高可靠要求。
4. Redundant backup of fire protection system ring network: Adopting a dual channel redundancy design of "CAN+fiber optic" to construct a fiber optic ring network. Under normal operating conditions, the CAN bus transmits data, with fiber optic cables serving as backup links; When a fire breaks the cable or a single point link fails, the fiber optic ring network automatically bypasses to ensure zero interruption of communication between the fire control host, fire extinguishing device, and emergency exhaust system, meeting the high reliability requirements of "zero misoperation and zero leakage" for energy storage fire protection.
5.储能消防与EMS系统联动控制：消防系统需与能源管理系统（EMS）协同，火情时快速切断故障电池簇电源。CAN转光纤打通消防CAN网络与EMS通信链路，实现微秒级数据交互：消防主机检测到热失控时，通过光纤下发指令，EMS立即执行断电、隔离操作，同时启动对应舱室灭火装置，形成“监测-预警-断电-灭火”闭环控制。
5. Energy storage fire protection and EMS system linkage control: The fire protection system needs to cooperate with the energy management system (EMS) to quickly cut off the power supply of the faulty battery cluster in case of a fire. CAN to fiber optic connects the fire CAN network and EMS communication link, achieving microsecond level data exchange: when the fire host detects thermal runaway, it sends instructions through fiber optic, and EMS immediately performs power-off and isolation operations, while starting the corresponding cabin fire extinguishing device, forming a "monitoring warning power-off fire extinguishing" closed-loop control.
