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.
