Problems solved by technology
[0006] 1. Both are suitable for online monitoring, but not for offline inspection
The online monitoring system of vibration and strength is still in the research and experiment stage, with high cost and poor reliability, and it has not yet been possible to promote the application of power grids
[0007] 2. The above two patents only cover vibration, not strength
[0008] 3. The above two patented monitors are powered by 220V AC power supply or solar power, and cannot be used for inspection
[0009] 4. The positions of the monitoring points of the above two patents can only be fixed in several positions, and there are few monitoring points

The invention discloses a power transmission tower intensity and vibration off-line intelligent routing inspection system. The power transmission tower intensity and vibration off-line intelligent routing inspection system comprises a power transmission tower intensity and vibration off-line intelligent routing inspection instrument. The power transmission tower intensity and vibration off-line intelligent routing inspection instrument comprises a movable strain sensor, an accelerometer, a two-channel signal conditioning instrument and a two-channel signal acquisition processor. The movable strain sensor and the accelerometer are connected respectively to the two-channel signal conditioning instrument. The two-channel signal conditioning instrument is connected to the two-channel signal acquisition processor. The two-channel signal acquisition processor is connected to a data processing device. The invention also discloses an early warning method of the power transmission tower intensity and vibration off-line intelligent routing inspection system. The power transmission tower intensity and vibration off-line intelligent routing inspection system realizes on-line monitoring, has high accuracy, safety and reliability, can be used for daily detection of a power transmission line, saves manpower and material resources, and solves the problem that the existing routing inspection system adopts a visual inspection method.
Description
technical field [0001] The invention relates to a power monitoring technology, in particular to an off-line intelligent inspection system for the strength and vibration of a power transmission tower and an early warning method thereof. Background technique [0002] The transmission tower system is subject to factors such as strong winds, ice, earthquakes, foundation settlements, landslides, geological changes in goafs, etc., resulting in stress exceeding the limit or vibration fatigue. . At present, it mainly relies on line maintenance personnel to detect changes in the tower through visual inspection, and there is no corresponding database and evaluation method for the reliability of the tower. [0003] Chinese patent ZL200820184986.2 discloses an online monitoring and wireless remote transmission system for the environmental vibration state of a transmission tower, which includes an on-site acquisition station and a master station. The on-site acquisition station includes...
