The invention provides a testing method of a vibration response test for a high-tower structure of transmission line of transmission of vibration signals and stimulation by taking wind load as external environment in a wireless mode. The method has the characteristics of simple and convenient operation and analysis and higher precision compared with the traditional vibration response testing means in a wired transmission and hammer method. Therefore, relational environment parameters motivated by environment are confirmed through a meteorological environment monitoring device, the vibration response of an iron tower is tested by the selected accelerating sensor, the test data of the vibration response of the high-tower structure of transmission line is transmitted by applying the wireless sensor, and finally modal mode parameters of the high-tower structure of transmission line is confirmed through the back-end process of the monitoring system.
