光纤硅光麦克风声纹传感器

Fiber-Optic Silicon Photonic Microphone Sensor
型号 / Model: BLY-SOACS-1-XXX

产品概述 Product overview

基于硅光反射脉冲编码与光纤传输，采集设备运行声、冲击、摩擦、泄漏及异常声纹，配合分析平台进行特征提取、事件识别和预测性维护。传感头与加速度版本采用相近的外形、安装与尾纤接口平台。
Uses silicon photonic reflective pulse coding and optical transmission to acquire operating sounds, impacts, friction, leakage and abnormal acoustic signatures. An analysis platform provides feature extraction, recognition and predictive maintenance. The head shares a similar mechanical, mounting and pigtail platform with the accelerometer version.

20 Hz–20 kHz声学频率响应，频率分辨率1 Hz；典型信噪比≥65 dB（A计权），声学过载点≥115 dB SPL。指标需结合配套解调、采样和分析窗口实现。
Acoustic response spans 20 Hz–20 kHz, with 1 Hz frequency resolution, typical A-weighted SNR ≥65 dB and acoustic overload point ≥115 dB SPL. These specifications require compatible interrogation, sampling and analysis windows.

典型应用 Typical applications

电力能源：变压器、发电机、风机、升压站与储能；石化：炼化、压缩机、储罐、管线与装卸栈台；矿山：井下设备、皮带机、转载机、泵站与巷道；交通土木：轨道、桥梁、隧道、管廊与边坡。
Power: transformers, generators, wind turbines, substations and storage; petrochemicals: refining, compressors, tanks, pipelines and terminals; mining: underground equipment, conveyors, transfer stations, pumps and galleries; infrastructure: railways, bridges, tunnels, utility corridors and slopes.

技术参数 Technical specifications

接口与安装 Interfaces and installation

配置示例：BLY-SOACS-1-025。尾纤长度及接口按订货配置确定。
Configuration example: BLY-SOACS-1-025. Pigtail length and connector follow the ordered configuration.

使用Ergo1665胶粘安装于清洁、平整表面，按安装要求固定方向并保护尾纤；带保护及不带保护尾纤最小弯曲半径均为50 mm。传感头靠近声源或关键结构布置，避免不必要的松动与冲击。
Bond with Ergo1665 on a clean, flat surface; align and secure the head as required and protect the pigtail. Minimum bend radius is 50 mm for both protected and unprotected versions. Place near the source or structural point and avoid loose mounting or unnecessary impacts.

尾纤超过标准3 m时，可通过匹配的光纤接续延长，连接器处理、熔接与保护由合格人员按光路设计完成；总光损耗与链路长度需满足配套解调仪要求。接口及尾纤长度可定制。
For lengths beyond the standard 3 m pigtail, extend using compatible fiber splicing. Qualified personnel should handle connector removal, splicing and protection in accordance with the optical design. Total loss and length must meet interrogator requirements; connectors and pigtail lengths are configurable.

与BLY硅光解调仪及上位机声纹分析平台配套使用。声纹识别效果取决于传感头布点、声源距离、背景噪声、被测结构及模型训练。
Use with a BLY silicon photonic interrogator and host acoustic-analysis platform. Acoustic recognition depends on sensor placement, source distance, background noise, the monitored structure and model training.

传感头频响、主机扫描频率与接口输出频率分别规定。采集2 kHz或20 kHz原始波形需要足够的采样率与传输带宽；≥50 Hz状态输出不能直接等同于这些原始波形带宽，需选配并确认高速采集模式。
Sensor response, interrogator scan rate and interface output rate are separate specifications. Raw 2 kHz or 20 kHz waveforms require sufficient sampling and transport bandwidth. A ≥50 Hz status output does not establish these raw-waveform capabilities; confirm the required high-speed acquisition mode.

IP、防腐及过载指标按对应配置的试验条件使用。无源光纤的电气隔离不代替整套系统在危险区域所需的适用性验证。
Apply ingress, corrosion and overload ratings under the test conditions for the supplied configuration. Passive-fiber electrical isolation does not replace complete-system suitability verification for hazardous areas.
