摘要
为了解决复杂电缆隧道内部监测装置和设备的无线数据传输问题,文章通过分析电缆隧道复杂环境下的电磁波传输特征,结合现场实际测试,分析了电缆隧道弯道结构无线通信的难点。采用Mist Mesh低功耗无线自组网传感技术,通过自适应组网等方式解决电缆隧道弯道、多层竖井等复杂环境下的无线传感难题,并通过现场实验验证了该无线自组网的可靠性,为后续电力隧道的无人巡检、在线监测、故障点定位、应急通信等研究工作提供了技术基础。
In order to solve the problem of wireless data transmission of monitoring devices and equipment in complex cable tunnels,this paper analyzes the characteristics of electromagnetic wave transmission in the complex environment of cable tunnels,and the difficulties of wireless communication in cable tunnel bend structures through actual field tests.Then,Mist Mesh low-power wireless ad hoc network sensing technology is used to solve the problem of wireless sensing in complex environments such as cable tunnel bends and multi-layer shafts through adaptive networking and other methods.Finally,the reliability of the wireless ad hoc network is verified through field experiments,which provides a technical basis for the subsequent unmanned inspection,online monitoring,fault location,and emergency communications of power tunnels.
