Research On Tower Defense Overturn Monitoring Technology In Coal Mine Subsidence Area

Move forward,with the pace of industrialization and the rapid development of the society,the development and utilization of coal resources is on the fast track,for our country's economic growth and social development made great contribution.But,with the excessive exploitation of coal resources exploitation,an expansion of the mined-out area,cause a lot of ground subsidence,and set up above the mined-out area of transmission lines especially affected by the goaf collapse,seriously affected the normal production and life of the people's power,and the rising of social contradictions.Mined-out area within the transmission tower vulnerable to the threat of goaf collapse.When the goaf collapse occurs,due to different subsidence situation,the transmission tower foundation in horizontal,vertical and longitudinal move on three directions,often happen tower displacement of tower building deformation,tearing,forming line to ground distance,discharge distance smaller,guide,ground wire spacing is not enough,insulator string tilting,factors affecting the operation of power grid is not safe.Aiming at the existence of mined-out area power grid in these unsafe factors,at present,the traditional manual patrol is the main means to find these factors,however,due to the limitations of the naked eye,it is very easy to overlook some dangerous omens,when patrol researchers found that the transmission line has been in danger,power is likely to have accidents.In order to avoid power accident,timely,accurately find tower real-time state,you need a reliable,stable,proactive monitoring system,the timely detection of evil omen events,predict risk events,helps the power sector in risk control,to ensure the safe and stable operation of power grid.Goaf tower Angle tension real-time online monitoring system on the Windows operating system platform to develop a set of user monitoring tower data management system,based on predict risk events,helps the power sector in risk control,to ensure the safe and stable operation of power grid.Goaf tower Angle tension real-time online monitoring system on the Windows operating system platform to develop a set of user monitoring tower data management system,based on the tower in longitudinal and lateral tilt tilted and thread tension data of online monitoring,at the same time using quadratic exponential smoothing forecast forecast data processing,combined with the design parameters given tower tilted early warning information,to monitor personnel provide short-term forecasting data,to carry out the tower tilted online monitoring,early warning capability.Tower Angle tension real-time online monitoring system is related to mechanics,computer,communications,and other professional complex system engineering,need to find out the poles distribution area distribution and characteristics of mined-out area,reveals the influence law of tower tilted,collect data of ground surface deformation,and the mined-out area of distribution of transmission lines,realize the tower slope deformation forecast.Selecting typical tower tilting monitoring research of monitoring the installation position of the system hardware,ommunication mode,software development,such as selecting the best monitoring program,through the analysis and study of monitoring data,designed to give tower tilted early warning information,achieve early discovery,early correct,to run the department in a timely manner to master tower safety operation to provide technical support of coal mining subsidence of transmission line safe operation.
