Online monitoring method of transmission tower inclination angle

Abstract

The invention discloses an online monitoring method of a transmission tower inclination angle, and solves the economical, practical and limited use range problems in the existing method. The online monitoring method comprises the following steps: acquiring monitoring signals of a transmission tower to generate monitoring data, transmitting the monitoring data to an online monitoring server in real time, processing the monitoring data by a tower-line system mathematical model to obtain calculating data, transmitting the calculating data to a remote data server to be stored, and browsing and analyzing the data by a user. Through full utilization of an advanced database management technology, a graphical display technology and an internet communication technology of the computer, and through monitoring of several measured values which are sensitive to inclination of the transmission tower, the inclination angle of the transmission tower can be reliably monitored at high precision for a long time. The variation trend of the monitoring data can be conveniently operated, retrieved and browsed; the daily work can be done; and the inclination angle can be centrally managed and monitored with other systems on the same platform.

Description

technical field [0001] The invention relates to the monitoring technology of the transmission line, more specifically, relates to an on-line monitoring method of the transmission line, which can be used for monitoring the inclination state of the transmission tower in the coal mining subsidence area. Background technique [0002] After the underground coal seam in the mining area is mined, the overlying rock layer will lose its support, and the original balance condition will be broken, causing the overlying rock layer to deform, collapse and damage, and finally lead to large-scale subsidence and depression of the surface. my country is a big coal mining country. With the increase of mining volume, the subsidence area caused by coal mining is expanding day by day, and more and more high-voltage transmission lines have to pass through the goaf of coal mines. Since most transmission towers use split foundations, due to the influence of surface deformation, uneven settlement, i...

Problems solved by technology

If the inclination sensor is used to accurately monitor such a small angle value, there are many problems in terms of economy and practicability; and the method of using the strain sensor to measure the strain of the tower body can only be applied to structural forms such as electric poles and steel pipe poles. However, for the widely used lattice angle steel tower, it is difficult to establish a direct relationship between the tower body strain and the inclination angle, and its application range is also limited.

From the above analysis, it can be seen that the existing transmission tower tilt monitoring methods have limitations in economy, practicability and scope of use in actual application, and have not completely solved the problem of transmission tower tilt monitoring.
