中文摘要：受"三高"环境客观因素的影响,终端运行状态的监测效果往往难以得到保障,为此提出面向热带海岛"三高"环境的配电网智能终端运行状态全天候监测研究.部署了由耐候型传感器与集成化边缘计算设备组成的采集模块,利用先进的红外热成像技术,结合定制化的API接口,实时捕获智能终端热图像视频流,并根据环境特性动态,利用VideoCapture()函数调整视频分帧处理的策略;采用基于TCP协议的面向连接套接字技术,实现边缘设备与远程监控中心(即云平台)间的高效、可靠数据传输;引入数据降维-因子分析算法,对配电网智能终端热图像视频流数据进行分析,提取异常状态信息.在测试结果中,该方法对不同终端设备的监测效果始终表现良好,且对应输出结果与实际状态数据间的拟合系数均在0.96以上;与对照组相比,其稳定性和可靠性均具有明显优势.

外文标题：All-weather Monitoring of Operating Status of Distribution Network Intelligent Terminal in"Three High"Environment of Tropical Islands

外文摘要：Affected by the factors of"three-high"environment,the monitoring utility of terminal operating status is often difficult to be guaranteed.Therefore an all-weather monitoring study of distribution network intelligent terminal operating status for"three-high"environment on tropical islands is proposed.The acquisition module composed of weather-resistant sensor and integrated edge computing device is deployed.The advanced infrared thermal imaging technology and custom-ized API interface are used to capture the thermal image video stream of intelligent terminal in real time,and the Video-Capture()function is used to adjust the video frame processing strategy according to the dynamic characteristics of the en-vironment.The connection-oriented socket technology based on TCP protocol is adopted to realize efficient and reliable da-ta transmission between edge devices and remote monitoring centers(i.e.,cloud platforms).The data dimensionality re-duction-factor analysis algorithm is introduced to analyze the thermal image video stream data of intelligent terminals and extract abnormal status information.In the test verification,the proposed method achieves stably satisfactory monitoring effect for various terminal devices,and fitting coefficients with actual state data of above 0.96,which demonstrates its po-tential superiorities in stability and reliability.
