Description

Technical Field

[0001] The invention relates to the technical field of high-altitude meteorological data detection, and in particular to a method for identifying a dropsonde placement position number. Background Art

[0002] High-altitude meteorological data detection technology is an important branch of meteorological data. The detection methods include traditional balloon-borne sondes, dropsondes, airborne meteorological radars, etc. Compared with traditional balloon-borne sondes, dropsondes have the advantages of being independent of the launch site, being highly maneuverable, and being able to be dropped in designated areas. Compared with airborne meteorological radars, dropsondes have the advantages of being far away and having low equipment costs. Dropsondes will continue to be an important detection method in the meteorological field, playing an important role in weather forecasting, environmental monitoring, disaster warning and rescue, aerospace, scientific research, and education.

[0003] Dropsondes are generally combined with drones in the form of embedded or pods with drones with the help of drone platforms. In order to collect high-altitude meteorological data more finely, a detection mission usually requires the release of multiple dropsondes, and each dropsonde is independently loaded and released through a launcher. At the same time, considering that the dropsonde is powered by a built-in lithium battery, in order to ensure the product endurance during meteorological detection, the lithium battery is disconnected before release, and the dropsonde is not powered. When the dropsonde performs meteorological detection tasks, the dropsonde lithium battery needs to be powered on and loaded into the sonde launcher. The dropsonde needs to be activated and searched for stars before being released. When the launcher releases the dropsonde, the gas source needs to be turned on to provide a power source for the dropsonde. In view of this requirement, a one-to-one correspondence table must be established between the launcher and the dropsonde. The activation of the dropsonde can be distinguished by its own ID number, and the launcher is determined by its physical location. However, the dropsonde needs to be separated from the launcher after being released, and it is not possible to directly establish a one-to-one correspondence between the dropsonde and the launcher using a conventional communication interface. After the dropsonde is loaded into the launcher, the corresponding launcher cannot obtain the ID number of the loaded dropsonde through the conventional communication interface. Summary of the invention

[0004] The purpose of the present invention is to provide a method for identifying a dropsonde delivery station number, so as to solve the technical problem in the prior art that after the dropsonde is loaded into the launching device, the corresponding launching device cannot obtain the ID number of the loaded dropsonde through a conventional communication interface.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The present invention provides a method for identifying a dropsonde placement position number, which is based on a dropsonde system for identifying a dropsonde placement position number. The dropsonde system includes an airborne control device, a radio frequency switch, a plurality of transmitting devices, and a plurality of corresponding dropsondes;

[0007] The method for identifying the sonde placement station number comprises the following steps:

[0008] S1. After the airborne control device is powered on, each channel of the RF switch is tested in place one by one;

[0009] S2. The airborne control device records the presence of the dropsonde in each channel of the RF switch and the corresponding dropsonde ID number;

[0010] S3, connecting a plurality of launching devices to corresponding dropsondes;

[0011] S4, making the transmitter station number correspond to the RF switch channel number;

[0012] S5. Make the dropsonde ID number correspond to the launcher station number to complete station number identification.

[0013] Optionally or preferably, the onboard control device controls the RF switch via an RS422 bus and establishes a RF path with an input end of the RF switch.

[0014] Optionally or preferably, the dropsonde system further comprises an airborne satellite signal;

[0015] The airborne satellite signal provides the dropsonde with the satellite signal required for star search and positioning through the radio frequency switch;

[0016] The dropsonde is arranged in the launching device.

[0017] Optionally or preferably, the method in S1 for the on-site detection of each channel of the RF switch by the airborne control device is as follows: the airborne control device detects whether there is a dropsonde online on each channel of the RF switch, and if the dropsonde is online, it is recorded as being in place, otherwise it is recorded as not being in place.

[0018] Optionally or preferably, the method in S2 for the airborne control device to record the presence of the dropsonde in each channel of the radio frequency switch and the corresponding dropsonde ID number is:

[0019] S21, the onboard control device is powered on and starts traversing the delivery stations;

[0020] S22, the airborne control device sends a channel control instruction to the RF switch, and the initial channel is 1;

[0021] S23, determine whether a reply is received that the channel switching is successful, if so, the switching is successful, otherwise the traversal ends;

[0022] S24, the airborne control device sends a presence query command to the radio frequency switch;

[0023] S25, determining whether a reply to the in-place query is received, if a reply is received, recording the ID number of the dropsonde and the channel selected by the radio frequency switch to form a corresponding table, otherwise determining the number of in-place queries of 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, return to step S22, where N is the total number of channels of the RF switch.

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

[0026] Optionally or preferably, in S25, the onboard control device determines whether a presence query reply is received within 100ms. If no reply is received, it determines whether the number of presence queries for the current channel is greater than or equal to three times. If so, it enters S26, otherwise repeats step S24.

[0027] Based on the above technical solution, the present invention can at least produce the following technical effects:

[0028] The method for identifying the work station number of a dropsonde provided by the present invention adopts a wired method to realize the activation and placement of a radio frequency control device and a dropsonde, and adopts a channel switching method to realize the work station number identification of a launching device, thereby avoiding the manual identification method of the dropsonde ID number and the work station number, improving the identification efficiency of the work station number, and avoiding the identification errors that may be caused by manual identification of the work station number.
