Unmanned aerial vehicle (UAV) dropsonde and method for releasing and controlling same

Abstract

The invention relates to an unmanned aerial vehicle (UAV) dropsonde and a method for releasing and controlling the same. A global positioning system (GPS) antennal, a GPS receiving unit, a battery, a sounding acquisition control circuit, a wireless transmission unit, a parachute, an air pressure sensor, a temperature sensor and a humidity sensor are arranged in a dropsonde shell; a transmission antenna is installed on the shell; the upper part of the shell is connected with a hanger; the upper surface of the shell is fixedly provided with contacts; the battery is connected with the GPS receiving unit, the wireless transmission unit and the sounding acquisition control circuit through a relay to form a control loop; two contact reeds connected with the contacts are parallelly connected to the control loop; the air pressure sensor, the temperature sensor and the humidity sensor are fixed outside a cabin; guide lines of the air pressure sensor, the temperature sensor and the humidity sensor are respectively connected with control contacts of a load control circuit. Electromagnet can be selected to lock or release the UAV dropsonde, and the method for releasing and controlling the UAVdropsonde has a simple principle and effective protection measurements, and can be used for effectively and directly acquiring the temperature data, the humidity data and the air pressure data of a vertical atmospheric section and sending the data back to a ground center in real time.

Description

technical field [0001] The invention relates to a dropsonde installed on an unmanned aircraft and a release control method thereof. Background technique [0002] Since the collection of meteorological sounding data, the release of radiosondes still adopts the method of manually releasing sounding balloons in many more developed countries. This traditional method of releasing balloons has continued for nearly a hundred years, and it is very difficult to operate. , the accuracy is small, and it is necessary to closely track the released balloon and radiosonde through the radar. If it encounters strong winds, heavy fog, or due to manual tracking for a long time, it is easy to mistakenly receive the radar. The wrong signal is used as the main signal, thereby shortening the tracking time and losing the weather detection data. In order to avoid the error caused by the time of launching the ball and the signal reception, and to track the balloon in the shortest time and collect th...
