Abstract

The invention provides a drop-down detector and a detection system, and relates to the field of high-altitude meteorological detection. The detector comprises a first umbrella cover, a main body part,and a plurality of communication antennas, wherein the main body part is cylindrical, and a meteorological information acquisition and processing device is arranged in the main body part; the plurality of communication antennas are electrically connected with the meteorological information acquisition and processing device, a first end of each of the plurality of communication antennas is movablyconnected with a periphery of the main body part at the same interval, and the second ends of the plurality of communication antennas are connected to an inner edge of the first umbrella cover at thesame interval; and after the detector is put in, the plurality of communication antennas are unfolded towards the periphery by taking the main body part as a center and are fixed at positions forminga first angle with an axis of the main body part so as to support the first umbrella cover. According to the drop-down detector provided by the invention, wind resistance of the detector can be improved, and a data transmission distance of the detector is increased.

Description

technical field [0001] The invention relates to the field of high-altitude meteorological detection, in particular to a drop-down detector and a detection system. Background technique [0002] The drop detector is a one-time use high-altitude meteorological instrument, which is brought to a designated area by an aircraft (for example, a drone or an airship) and dropped at high altitude. After the launch, the radiosonde is driven by a parachute to float freely to the ground to collect weather information at different altitudes. [0003] figure 1 It is a drop-type detector in the prior art. Such as figure 1 As shown, the existing drop-type detector is composed of a parachute 1, a vibration-damping rope 2, a detector body 3 and a casing 4. After being dropped, the parachute 1 is ejected from the casing 4 and opened, and the vibration-damping rope 2 is connected to the inside of the casing. The set detector main body 3 is connected, thereby driving the detector to float down...
