用于智能巡检的可见光通信系统设计

摘要

为了解决电网业务环境中许多无线电信号深度衰落及电磁敏感等场景的通信问题，提出了一种基于可见光通信与电力线通信深度融合的网络架构，该架构克服了传统架构网络改造工程规模大、成本高的缺点，成本低并且容易实现。并对基于该架构系统业务流程、功能与主站平台设计进行了分析，进一步介绍了将可见光通信与电力线通信深度融合技术应用于典型的电网业务场景—变电站和电缆隧道智能巡检，可以为现场巡检人员与后台管理人员提供双向语音通信，并对现场巡检人员进行定位服务，以保障巡检人员的人身安全和电网生产安全。%In order to solve the communication problem of many radio signals fading or electromagnetic sensitive in power grid business scene,a kind of integrated network architecture visible light communication(VLC) and power line communication (PLC) is put forward. This architecture is low cost and easy to implement which overcomes the shortcoming of the traditional network architecture. And the business process,function and design of master station platform are analyzed. This paper introduces the application of deep integrated technology of visible light communication and power line communication to the typical grid service scenario— intelligent inspection of substation and cable tunnel. The VLC-PLC system could provide voice communication service between on-site inspectors and backstage management personnel,and positioning service for on-site inspectors,ensuring the safety on-site inspectors and security of power production.
