Abstract

The invention relates to a high-precision deformation monitoring method of a wide-area electric iron tower based on a Beidou system. The high-precision deformation monitoring method comprises the following steps: judging whether real-time dynamic centimeter-grade monitoring requirements are met or not according to monitoring precision of a Beidou foundation CORS network; if so, obtaining iron tower monitoring data through a network RTK virtual reference station method; otherwise, obtaining the iron tower monitoring data through a double-monitoring-point base line attitude measurement method; processing and analyzing the monitoring data, and calculating an inclined angle and a sedimentation value of the iron tower; if the inclined angle and the sedimentation value of the iron tower exceed limit requirements of operating regulations of a power transmission line, determining a tower position coordinate and issuing a field inspection and maintenance instruction; if the inclined angle and the sedimentation value of the iron tower do not exceed the requirements of the operating regulations of the power transmission line, judging an inclining trend of the iron tower. The monitoring method provided by the invention can be used for carrying out all-weather, all-time and automatic monitoring on the wide-area electric iron tower; potential safety hazards are found and warned in time, and the manual inspection cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of power equipment monitoring, in particular to a high-precision deformation monitoring method for power towers in a wide area based on the Beidou system. Background technique [0002] The transmission line is the main artery of the power grid. The safety of the power tower is in an important position in the power grid. Due to the influence of human factors such as geological environment, natural disasters, and engineering construction, the tower will be tilted and unevenly settled, which will cause the transmission line to be damaged. The tower collapsed. At present, the traditional tower monitoring method is mainly carried out by combining manual inspection and sensor monitoring. These two methods not only consume a lot of manpower and financial resources and are inefficient, but also the measurement accuracy cannot meet the requirements of DL-741 regulations. In addition, in actual operation, due to the...
