As shown in fig. 1-3, a buoy-type dropsonde includes a pod and a sonde disposed in the pod.

The sonde is provided with a positioning system, a parachute 1, a sensing system, a transmitter, an air bag and a control system. The sensing system comprises a plurality of sensors for acquiring air meteorological data and sea surface meteorological data and an impact sensor 5 for detecting the impact force applied to the sonde. The sensors for acquiring the air meteorological data and the sea meteorological data comprise a temperature sensor, a humidity sensor and an air pressure sensor. Parachute 1 is connected with parachute opener, and the gasbag is connected with gasbag igniter 4, and gasbag igniter 4 is connected with impulse sensor 5 electricity. The gasbag is including the symmetry setting first gasbag 2 and the second gasbag 3 in sonde both sides, is connected with gasbag point firearm 4 on first gasbag 2 and the second gasbag 3 respectively. In addition, when the sonde is used on land, the air bag can be opened before the sonde falls to the ground, so that the impact force is reduced when the sonde falls to the ground, the sonde can continue to work after falling to the ground to a certain extent, and the value of the sonde is exerted to the maximum extent. The control system is respectively and electrically connected with the umbrella opener, the sensing system, the transmitter and the air bag igniter 4.

The conventional sonde is unable to transmit data to the aircraft platform before it falls to the surface because of the distance or other factors that cause the data reception to be interrupted. For solving the data transmission problem, the utility model discloses a two sets of signal emission systems of installation in the formula of throwing sounding device under the buoy type, the transmitter is including being used for giving unmanned aerial vehicle's first transmitter with aerial meteorological data transmission and being used for giving the second transmitter of ground basic station with aerial meteorological data and sea meteorological data transmission. And the second transmitter transmits the air meteorological data and the sea surface meteorological data to the ground base station through the Beidou, the buoy or the drop base station. The first transmitter is responsible for transmitting aerial meteorological data to the unmanned aerial vehicle in the falling process of the sonde, and then transmitting the aerial meteorological data to the ground base station from the unmanned aerial vehicle. When the sonde falls to the sea surface, the other set of transmitting system is started, and the second transmitter is responsible for directly transmitting the sea surface meteorological data to the ground base station through the annular antenna after the sonde falls to the sea surface by means of the Beidou, the buoy, the launching base station and the like.

The sonde is also internally provided with an automatic activation module which is electrically connected with the control system. The sonde is also provided with a standby data transmission antenna.

The working principle of the buoy type downward-throwing sounding device is as follows: the sonde is activated by an activation device in the gondola and then ejected out of the gondola, falling to a certain height, triggering the parachute opener to open the parachute 1. In the falling process, the sensor acquires meteorological data, the data are collected to the control system through the collecting circuit and are packaged and encoded, and the aerial meteorological data are sent to the receiver carried by the unmanned aerial vehicle through the first transmitter. When the sonde falls to the sea surface by 50 meters, the locking state of the air bags is released, when the sonde falls to the sea surface and is impacted, the impact sensor 5 receives vibration response, the air bag igniter 4 is started, the air bags are inflated and expanded, the two air bags are respectively unfolded from the two sides of the sonde to provide floating buoyancy on the sea surface for the sonde, the sonde continues to acquire sea surface meteorological data through the sensors after falling to the sea surface, and the second transmitter is used for transmitting the data to the ground base station in a Beidou mode, a buoy mode, a drop-in base station mode and the like.

The air inflation principle of the air bag is as follows: when the sonde impacts the sea surface, impact force is generated, the airbag igniter 4 receives a signal sent by the impact sensor 5, the igniter detonates an ignition agent to generate a large amount of heat, and sodium hydroxide in the airbag is heated and decomposed by utilizing a thermal effect reaction to generate a large amount of nitrogen so that the airbag is inflated and expanded.
