Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-altitude meteorological data detection, and in particular to a method for identifying a launch site number of a dropsonde. BACKGROUND

[0002] High-altitude meteorological data detection is an important branch of meteorological data, and detection methods include traditional ball-borne sounding instruments, dropsondes, airborne weather radars, etc. Compared with traditional ball-borne sounding instruments, dropsondes have the advantages of not relying on launch sites, strong mobility, and being able to be launched in designated areas. Compared with airborne weather radars, dropsondes have the advantages of long action distance and low equipment cost. Dropsondes will continue to be an important detection method in the field of meteorology and play an important role in weather forecasting, environmental monitoring, disaster warning and rescue, aerospace, scientific research and education, etc.

[0003] Dropsondes are generally combined with unmanned aerial vehicles (UAVs) in the form of being embedded or suspended in the UAVs. To collect high-altitude meteorological data more finely, multiple dropsondes are usually launched in one detection task, and each dropsonde is independently filled and launched by a launch device. Meanwhile, considering that dropsondes are powered by built-in lithium batteries, the lithium batteries are in a disconnected state before launch to ensure the endurance of the dropsondes during meteorological detection. When the dropsondes perform meteorological detection tasks, the lithium batteries of the dropsondes need to be powered on and filled into the launch device. Before the dropsondes are launched, they need to be activated and positioned. When the launch device launches the dropsondes, the gas source needs to be turned on to provide power for launching the dropsondes. In view of this requirement, it is necessary to establish a one-to-one correspondence table between the launch devices and the dropsondes. The activation of the dropsondes can be distinguished by their ID numbers, and the launch devices are determined by their physical positions. However, after the dropsondes are launched, they need to be separated from the launch devices, and a one-to-one correspondence cannot be established between the dropsondes and the launch devices through a conventional communication interface. After the dropsondes are filled into the launch devices, the corresponding launch devices cannot obtain the ID numbers of the filled dropsondes through a conventional communication interface. SUMMARY

[0004] The present application aims to provide a method for identifying a launch site number of a dropsonde to solve the technical problem that, in the prior art, after a dropsonde is filled into a launch device, the corresponding launch device cannot obtain the ID number of the filled dropsonde through a conventional communication interface.

[0023] S25, determining whether a reply to the in-place query is received, if a reply is received, recording the dropsonde ID number and the RF switch selection channel to form a corresponding table, otherwise determining the number of in-place queries for the current channel;

[0024] S26. Switch channels and determine the number of switched channels. If the number of switched channels is ≥ N, the traversal ends. Otherwise, the process returns to step S22, where N is the total number of channels of the RF switch.

[0025] Optionally or preferably, if the onboard control device does not receive a reply indicating successful switching within 500 ms in S23, the traversal ends.
