Problems solved by technology

[0003] At present, the monitoring of transmission towers is mostly carried out manually. If the monitoring personnel are not on the job, when there is a problem with the transmission tower, emergency treatment cannot be carried out, causing unnecessary losses.
In addition, manual monitoring is a heavy workload, high cost, and low reliability. Some transmission towers are distributed in places with poor environments, and it is difficult for monitoring personnel to reach them. As a result, many transmission towers are in a non-monitoring state, which is very prone to problems. in danger
[0004] Therefore, it is necessary to propose an online monitoring system and monitoring method for transmission towers to realize real-time monitoring of transmission towers, ensure the normal operation and maintenance of transmission towers, and avoid rapid aging and collapse of transmission towers due to vibration and other problems.

Embodiment 1

[0062] Such as figure 1 Shown is the transmission tower online monitoring system disclosed in this embodiment. Overall, the monitoring system is divided into three major parts, namely the signal acquisition device 1, the signal processing station 2 and the signal storage and processing center 3.

[0063] Wherein, the signal acquisition device 1 is arranged on the transmission tower, and the signal acquisition device 1 collects the vibration information of the transmission tower and the wind speed information of the location of the transmission tower and transmits the collected information to the signal processing station 2 . Since the monitoring system in this embodiment is on-line monitoring, technical personnel are not required to conduct on-site monitoring on the transmission tower, thereby solving the problem of inability to monitor due to poor geographical location of the area where the transmission tower is located. However, the monitoring system needs to set up a signal...

Embodiment 2

[0079] Such as figure 2 Shown is the transmission tower online monitoring method proposed in this embodiment, and the monitoring method is applied to the transmission tower online monitoring system as in the first embodiment. The monitoring method mainly includes two major steps. The first step is to conduct pre-acquisition monitoring on the transmission tower; the second step is to perform routine acquisition and monitoring on the transmission tower. After the transmission tower undergoes maintenance that causes structural changes, the pre-acquisition monitoring and routine acquisition monitoring will be performed on the transmission tower again.

[0080] When the transmission tower is monitored online for the first time, the transmission tower is pre-collected and monitored, and the sensor unit in the signal acquisition device collects the vibration displacement and wind speed of the transmission tower respectively, and then the various data collected by the sensor unit Th...

Abstract

The invention discloses a power transmission tower online monitoring system and monitoring method. The power transmission tower online monitoring system comprises a signal acquisition device, a signal processing station and a signal storage and processing center; the signal acquisition device is arranged on a power transmission tower; the signal acquisition device acquires the vibration information of the power transmission tower and the meteorological information of a location where the power transmission tower is located and transfers the acquired information to the signal processing station; the signal processing station is arranged in a range which adopts the power transmission tower as the center and a predetermined distance as the radius; the signal processing station collects the information acquired by the signal acquisition device, pre-processes the information and transmits the pre-processed information to the signal storage and processing center; and the signal storage and processing center receives the information pre-processed by the signal processing station, analyzes and stores the information. The power transmission tower online monitoring system and the power transmission tower online monitoring method are used cooperatively, and the abnormal situations of the power transmission tower can be discovered in time. The power transmission tower online monitoring system and monitoring method are simple and efficient in monitoring process and are excellent in monitoring effect, and can actually realize unmanned monitoring.

Description

technical field [0001] The invention relates to the field of remote state monitoring, in particular to an online monitoring system and a monitoring method for transmission towers. Background technique [0002] The transmission tower is one of the important equipment of the power transmission system, and the safety of the transmission tower is of great significance to ensure the reliability of the power supply of the power grid. A transmission tower is a towering structure that is slender, tall and soft. When there is strong wind, earthquake or vibration around the transmission tower, the transmission tower will vibrate violently, which can easily lead to structural damage, and even more serious collapse of the transmission tower. In addition, if the transmission tower is in a small vibration environment for a long time, although it will not cause damage to the transmission tower immediately, it will easily cause fatigue damage to the transmission tower, which will lead to t...
