Anemorumbometer field calibration system and method based on unmanned aerial vehicle technology

Abstract

The invention provides an anemorumbometer field calibration system and method based on an unmanned aerial vehicle technology. The system is mainly composed of a control system, an unmanned aerial vehicle (a second locator is accordingly arranged), a micro straight-flow wind tunnel, a to-be-calibrated anemorumbometer (a first locator is accordingly arranged), an acquisition card and a notebook computer. The anemorumbometer field calibration system is applicable to field calibration on an anemorumbometer of a natural disaster monitoring system along G-series high-speed railways and in use. Before the anemorumbometer field calibration system is provided, the anemorumbometer of the natural disaster monitoring system along the G-series high-speed railways only can be calibrated after being torndown and taken back to a laboratory, the process is complex in operation flow, both time and energy are consumed, efficiency is extremely low, and damage of an instrument can be easily caused in a dismounting process. The anemorumbometer field calibration system provided by the invention solves the problem of field calibration of the anemorumbometer and can be applied to the field calibration ofvarious anemorumbometers in service; and calibration operation of the anemorumbometer can be completed at relatively high efficiency and relatively low economic cost without influencing normal serviceof the instrument, no instrument is dismounted or mounted in the whole process, and security threat faced by an operator and the instrument is avoided.

Description

technical field [0001] The invention relates to the technical field of on-site calibration of anemometers, in particular to an on-site calibration system and method for anemometers based on unmanned aerial vehicle technology. Background technique [0002] In recent years, my country's high-speed railway construction has achieved world-renowned achievements. However, with the further extension of the high-speed railway network, high-speed trains are facing threats from various harsh wind environments. Due to the fast running speed of the train, the requirements for its own stability are extremely high, and the horizontal load generated by the strong wind can easily lead to traffic safety accidents. In order to avoid high-speed rail accidents caused by strong winds, the railway department installed wind speed and direction instruments along the high-speed rail to monitor the wind speed and direction along the line in real time. When the wind speed is greater than a certain lim...
