摘　　要：针对通信光缆对电力系统可靠运行的重要性日益凸显和其与电缆同沟敷设时防火手段匮乏的现状,设计了一种适用于电力沟道通信光缆的智能防火装置。首先设计了该装置具有的功能和整体架构;其次为了解决沟道内设备供电难的问题设计了利用可充电锂离子电池作为电源为该装置和其他防火信息采集设备供电;最后设计了该智能防火装置与前端防火信息采集设备采用有线通信、与后端监控系统采用目前应用最广的4G通信的通信方案,并与已有防火方案进行了对比。设计的智能防火装置不依赖外部电源,可随时随地采集线缆沟道内防火信息,通过边缘计算快速对火灾级别做出研判预警,能够大大提高火灾处理效率,在实际工程中具有较大的应用价值。In view of increasing importance of communication optical cable for reliable operation of power system and lack of fire prevention means when it is laid in the same trench with electric cables,this work designs and realizes an intelligent fire protection device for optical cables laid in power channel.Firstly,function and overall structure of the device are designed.Secondly,in order to solve the problem of difficult power supply for equipment in the channel,a rechargeable lithium ion battery is designed to provide power for the device and other fire protection information collection equipment.Finally,the communication scheme is designed in which the intelligent fire protection device communicates with the front-end fire protection information collection equipment by wire and with the back-end monitoring system by 4G that is the most widely used at present.The comparative analysis is also performed between the designed fire protection scheme and the existing scheme.The intelligent fire protection device designed in this work does not rely on external power supply and can collect the fire prevention information without time and location limit.Moreover,the newly designed device can utilize edge computing to realize fast judgment of the fire level and thus can greatly improve efficiency of fire treatment and has great application potential in practical projects.
