R&D Of Base Station Edge Type Intelligent Monitoring And Antenna Monitoring Terminal Height Measurement Technology

In the mobile communication area,base station engineering parameters are the important basis for network construction and optimization.This subject relies on the project of Base Station Antenna Engineering Parameter Acquisition and Analysis System which is supported by the Enterprise Innovation Fund of the Ministry of Science and Technology.The handheld base station engineering parameters acquisition terminal has problems on complex calibration,limited accuracy and measurement difficulty.The remote antenna monitoring system lacks the functions of visual interaction and antenna height monitoring.To solve the issues,this thesis proposes the antenna hanging height monitoring scheme and an intelligent base station edge monitoring system.Main works are as follows:1.Combined with the idea of power environment monitoring system and edge computing,an intelligent base station edge monitoring system is designed to complete the edge system structure,data acquisition modes,transmission processes,Web presentation and storage.The system builds a B/S small edge server,combining TCP/IP and Web Socket protocol,to complete data communication middleware.Final to present terminal monitoring data on the web page in real time,and realize the integration of base station construction measurement and remote monitoring.2.The research of antenna hanging height monitoring scheme is divided into four stages: introducing real-time differential datum points to eliminate atmospheric environmental interference;designing filtering algorithm to reduce the reverse error of differential barometric noise;designing an inertial sensor and barometer fusion altimetry algorithm to improve measurement accuracy;and introducing edge computing equipment to centralize all antenna hanging height data for distinguishing scenes and simplifying calibration.3.Collect data in real scenes,test the proposed dynamic correction and displacement authentication fusion algorithm,compare and analyze its performance.Make environmental monitoring terminal to test the real-time communication function of the system.Test the data presentation function of the front-end Web of the system.The system has the ability of internal and external monitoring coverage of base station,which can be used for long-time monitoring and base-station construction measurement.It makes up for the blank of monitoring function of the existing remote monitoring system,and has a less-than 0.15 meters monitoring average error.Error range of antenna hanging height construction survey is ?0.3 meters,which is 70% lower than the error range of the existing handheld acquisition terminal ?1 meter.
