Power transmission line iron tower inclination monitoring system based on space attitude sensor, and control method

Abstract

The invention provides a power transmission line iron tower inclination monitoring system based on a space attitude sensor, and a control method. An inclination angle of the power transmission line iron tower can be collected in real time, when the inclination state of the power transmission line iron tower changes, inclination angle data are remotely sent to a user. The power transmission line iron tower inclination monitoring system has the advantages of being high in reliability, high in response speed, low in cost and the like by combining the space attitude sensor with the wireless ad hocnetwork communication technology.

Description

technical field [0001] The invention belongs to the technical field of state monitoring of electric power transmission lines, and in particular relates to a power transmission line iron tower inclination monitoring system and control method based on a space attitude sensor. Background technique [0002] Affected by the natural environment and external conditions, earthquakes, lightning strikes, landslides, severe weather, aging and oxidation, as well as potential man-made theft and damage will bring some safety hazards to the tower, causing the tower foundation to slip, tilt and crack. Eventually, the tower body will be deformed, tilted or even collapsed, posing a greater threat to the safe operation of the power grid. [0003] At present, the tilting state of transmission line towers is mainly monitored by manual regular inspections and high-precision positioning technology based on Beidou navigation satellites.

Problems solved by technology

[0002] Affected by the natural environment and external conditions, earthquakes, lightning strikes, landslides, severe weather, aging and oxidation, as well as potential man-made theft and damage will bring some safety hazards to the tower, causing the tower foundation to slip, tilt and crack. Eventually, the tower body will be deformed, tilted or even collapsed, posing a greater threat to the safe operation of the power grid

[0003] At present, the tilting state of transmission line towers is mainly monitored by manual regular inspections and high-precision positioning technology based on Beidou navigation satellites. Among them, manual periodic inspections cannot effectively monitor the status of iron towers during operation in real time, and at the same time have certain Subjectivity, some parameters are difficult to measure manually, and it is not easy to find problems in time; the high-precision positioning monitoring system based on Beidou navigation satellites has good stability, and can dynamically and effectively monitor the tilt of the iron tower caused by the external environment, and the angle change resolution is better than 0.1 °, can replace the manual inspection method for dynamic monitoring of the tower, but the initial cost and post-operation and maintenance costs are high, which is not conducive to large-scale promotion and application
