The invention relates to a water surface flow velocity detection system under a high water condition and a detection method thereof, and belongs to the hydrology data measuring field; the detection system comprises a Beidou high precision difference positioning unit, a laser sensor, a radar flow velocity instrument, a wireless data transmission module, a host computer, a servo positioning module and a data acquisition module; the Beidou high precision difference positioning unit, the radar flow velocity instrument, the laser sensor and the servo positioning module are arranged in one piece toform a sensor device. The method can solve an inclination angle of the radar flow velocity instrument when the electromagnetic wave of the radar flow velocity instrument emits to an assigned section according to the accurate distance from the radar flow velocity instrument to the water surface and the horizontal distance from the sensor device to the to the section, thus effectively solving the measuring errors caused by cable vibrations, realizing accurate current measurement of the assigned section under the high water condition, preventing flow velocity instrument damages caused by fish lead diving flow measurement under the high water condition, and effectively ensuring the implementation of the hydrology flow measurement under the high water condition.
Description
technical field [0001] The invention relates to a water surface velocity detection system and a detection method thereof under high water conditions, and belongs to the field of hydrological data measurement. Background technique [0002] my country's vast land area and complex terrain lead to numerous rivers in our country. Coupled with climate change differences, our country's hydrological conditions are complex and diverse. Doing a good job in collecting and processing hydrological data is of great significance to production and disaster prevention. The traditional flow measurement method is to determine the position of the sensor device according to the upper and lower positions of the cable, which is inaccurate, has a large influence on the external environment, and has a large error; the traditional method measures the distance from the sensor device to the water surface inaccurately; the traditional lead fish measures the current water surface The flow rate detection ...
