Description

Technical Field

[0001] The present application relates to the technical field of sounding balloons, and in particular to a sounding balloon detection compensation control system and method. Background Art

[0002] Sounding balloons are mainly used to bring radiosondes to high altitudes in order to detect meteorological elements such as temperature, pressure, humidity and wind. At present, it is the main method of high-altitude detection in my country. With the development of intelligent meteorological detection and accurate prediction in my country, the accuracy requirements for the net lifting force of sounding balloons are becoming more and more stringent. The traditional method (suspending a balance valve under the balloon, and when the balance valve is pulled up by the buoyancy of the balloon, the staff closes the valve) can no longer meet the accuracy requirements. At present, many researchers have studied automated sounding balloon filling to achieve the purpose of replacing manual filling. Some researchers proposed to use a differential pressure transmitter for regulation, but the pressure difference is greatly affected by temperature, and the final result will have a large deviation. Some researchers proposed to use a gravity sensor for regulation, but because the gas is fluid, when the valve is closed when the control target is reached, there is already a delay in the entire system, and the actual value has exceeded the target value. Some researchers use flow controllers for regulation, but during the sounding balloon filling process, the gas will have an unstable flow rate and cannot achieve high-precision control. Therefore, how to achieve the accuracy control of the net lifting force of the filling during the sounding balloon filling process is of great research significance. At present, the precision control methods for sounding balloons are mainly concentrated on flow control, gravity control, and pressure difference control. There is currently no simple, effective, and reasonable and complete detection and compensation control system for the accuracy of the net lifting force during the filling process of sounding balloons.
