Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of meteorological sounding, in particular to the technical field of replay ball frequency point dynamic allocation and flat floating double ball frequency point dynamic allocation, and specifically relates to a frequency point dynamic allocation method in a sounding ball operation and a related device. BACKGROUND

[0002] The traditional scheme relies on fixed frequency band division. 400.35-400.95MHz is divided into 24 working channels (also known as frequency points in the meteorological field), each working channel occupies a bandwidth of 25kHz, and according to the spatial isolation of east-west spacing ≥800km and north-south spacing ≥600km, specific working channels are assigned to each Beidou sounding station in the country. Among them, 20 working channels (channels 1-20) are assigned to each Beidou sounding station in the country as main channels for one-time ball sounding operation, and 4 working channels (channels 21-24) are reserved as backup channels.

[0003] When a Beidou sounding station fails in one-time ball sounding operation, backup channels are provided for the station's secondary ball sounding operation. Generally, a static frequency band allocation method is used, that is, each sounding station is fixedly allocated two frequency point ranges, that is, two backup channels, from the four backup channels for the station's secondary ball sounding operation. However, static allocation cannot optimize the frequency points according to real-time needs such as the distance between stations and the current frequency point usage, so that the frequency point resources cannot be maximally utilized, and the frequency point allocation efficiency is low. Secondly, the spatial interference control is insufficient, and the current frequency point allocation scheme does not fully consider the influence of the geographical distance between devices and the spatial factors on frequency point conflicts. For example, if the working areas of two sounding stations are close to each other and use the same frequency point at the same time, it will cause co-frequency interference. Such interference may affect the accuracy of data, and even make some sounding operations unable to proceed smoothly.

[0004] Therefore, the existing frequency point allocation scheme is inefficient and prone to co-frequency interference affecting the accuracy of sounding data. SUMMARY

[0005] The present application provides a frequency point dynamic allocation method in a sounding ball operation and a related device to solve the problem of low efficiency and easy co-frequency interference affecting the accuracy of sounding data of the existing frequency point allocation scheme.

[0060] Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

The display device can include, but is not limited to, a personal computer, a television, and the like.

[0062] In addition, the term "and / or" in this document merely describes an associated relationship between associated objects, which means that there can be three relationships, for example, A and / or B can represent three cases of A alone, A and B together, and B alone. In addition, the character " / " in this document generally represents an "or" relationship between the front and rear associated objects.

[0063] In view of the low efficiency and the problem of easily causing frequency interference to affect the accuracy of sounding data of the existing frequency point allocation scheme, the present application proposes a frequency point dynamic allocation scheme in a sounding ball release service. The invention concept of the scheme is to dynamically and real-timely acquire the occupation state of all frequency points, create a dynamically changing white list for each ball release station; when any target ball release station has a re-ball release operation demand, the target ball release station corresponding white list is searched to find whether there is a backup frequency point, if yes, the target ball release station is allocated as the latest ball release frequency point, otherwise, a main frequency point is searched, if yes, the target ball release station is allocated as the latest ball release frequency point, otherwise, a temporary frequency point is searched, if yes, the target ball release station is allocated as the latest ball release frequency point, otherwise, the re-ball release operation is ended. Thus, through the priority level search and dynamic frequency point generation, the resource allocation rigidity problem in the traditional scheme is solved, and the dynamic allocation efficiency is improved; the adjacent frequency interval constraint and the geographical distance are jointly determined to reduce the spectrum conflict rate and improve the success rate of re-ball release and the reliability and accuracy of sounding data. Further, for double-ball ball release operation, the double-ball sounding information of the flat floating double-ball can be acquired from the connection database, the real-time second data information of the flat floating double-ball is acquired from the Redis, the double-ball receiving channel of the relay receiver closest to the flat floating double-ball within the first distance threshold is determined, and the resource efficient utilization of double-ball data reception is realized.

[0064] Referring to Figure 1 Fig. 1 is a step schematic diagram of a frequency point dynamic allocation method in a sounding ball release service provided by an embodiment of the present application. The execution subject of the method can be a frequency point dynamic allocation device, which can be a computer device, a tablet computer, a smart terminal, a smart wearable device, or the like electronic device with computer functions such as data calculation, processing, and storage, or a software module or component integrated in the electronic device.

[0065] As Figure 1 shown, the frequency point dynamic allocation method in the sounding ball release service can include the following steps:

[0066] Step 102: dynamically and real-timely acquire the occupation states of all frequency points, and create a dynamically changed white list for each ball release station according to the occupation states; wherein, the available frequency points stored in the white list satisfy the following interference constraint condition: the distance between all ball release stations using the same frequency point is not less than a first distance threshold, and the interval between the frequency points used by the ball release stations within the first distance threshold range is greater than a first frequency threshold.

[0067] In the scheme of the present application, the sounding ball release service can be single ball release or double ball release. All frequency points include: 24 frequency points and a preset frequency range; here, the preset frequency range can be 400.15 MHz ~ 406.00 MHz. It should be understood that, under the condition that the technical requirements are allowed and do not violate public morals, the preset frequency range can be adjusted according to the service demand. Therefore, all frequency points here can be frequency points that can provide reasonable allocation services for ball release stations or relay receivers in the sounding ball release service.

[0068] Wherein, the occupation state of the frequency point can include: which ball release station occupies it, the occupation time, etc. In specific implementation, the occupation state of each frequency point can be dynamically monitored, and whether the frequency point of a ball release station can be released is judged according to the frequency point usage time, distance, signal strength, etc., that is, the dynamic release of the frequency point can be realized, so as to update the white list in real time. It should be understood that the white list involved here can be understood as an available frequency point data storage table, and each ball release station can create an available frequency point data storage table through dynamic monitoring and statistics, and dynamically release the corresponding frequency point according to the frequency point usage condition, so as to update the corresponding available frequency point data table. The white list of each ball release station uses Redis database for distributed storage and update.

[0069] In each white list, the available frequency points need to satisfy the set interference constraint condition, that is, within the first distance threshold range centered on the ball release station: the available frequency point cannot be shared by other ball release stations, and the interval between the available frequency point and other frequency points within the first distance threshold range is greater than the first frequency threshold. In other words, the available frequency point not only avoids co-frequency interference, but also reduces adjacent frequency interference, so as to reduce the overall frequency point interference influence and improve the detection data accuracy.

[0070] It should be noted that a white list is created for each ball release station in the present application, and the white list contains only available frequency points and is dynamically updated. At the same time, a black list can also be created for each ball release station in the same group as the white list, and the black list records the unusable frequency points of the ball release station and is dynamically updated. The data format of the black list and the white list is the same.

[0071] The backup frequency point, the main frequency point and the temporary frequency point can be contained in the white list, and the frequency points satisfy the interference constraint condition of the available frequency point. Meanwhile, the allocation priority of the available frequency points can be set, wherein the allocation priority of the backup frequency point is the highest, the allocation priority of the main frequency point is the second, and the allocation priority of the temporary frequency point is the lowest.

[0072] Optionally, the first distance threshold value is 600km-650km; and the first frequency threshold value is 0.05MHz. Preferably, the first distance threshold value can be 600km. It should be understood that the first distance threshold value in the application is only an example, which can be flexibly adjusted according to the demand of the ball releasing service.

[0073] Step 104: When any target ball releasing station has a ball releasing operation demand, whether there is a backup frequency point in the white list corresponding to the target ball releasing station is searched.

[0074] If yes, step 106 is executed, otherwise, step 108 is executed.

[0075] Step 106: One backup frequency point found is allocated to the target ball releasing station as the latest ball releasing frequency point, and the white list of the corresponding ball releasing station is updated.

[0076] In this step, as long as one backup frequency point is found, the backup frequency point is allocated to the target ball releasing station as the latest ball releasing frequency point. Meanwhile, the white list of the corresponding ball releasing station is updated, that is, the occupation state of the backup frequency point is updated. Specifically, the following two aspects can be considered:

[0077] The white list containing the latest ball releasing frequency point is searched, and the ball releasing station with a distance less than a first distance threshold value from the target ball releasing station is screened out; the latest ball releasing frequency point is moved from the white list of the screened ball releasing station to the black list; and / or;

[0078] The ball releasing station with a distance less than a first distance threshold value from the target ball releasing station is searched, and the ball releasing station with an interval less than a first frequency threshold value between the ball releasing frequency point and the latest ball releasing frequency point of the target ball releasing station is screened out; the ball releasing frequency point of the screened ball releasing station is moved from the white list of the target ball releasing station to the black list, and the latest ball releasing frequency point of the target ball releasing station is moved from the white list of the screened ball releasing station to the black list.

[0079] Step 108: Whether there is a main frequency point in the white list corresponding to the target ball releasing station is searched.

[0080] If yes, step 110 is executed, otherwise, step 112 is executed.

[0081] When the backup frequency point does not meet the allocation, whether the main frequency point is recorded in the white list is searched.

[0082] Step 110: Assign the found one main frequency point to the target ball-putting station as the latest ball-putting frequency point, and update the white list of the corresponding ball-putting station.

[0083] In this step, as long as one main frequency point is found, the main frequency point is assigned to the target ball-putting station as the latest ball-putting frequency point of the target ball-putting station. At the same time, the white list of the corresponding ball-putting station is updated, that is, the occupation state of the backup frequency point is updated. Specifically, the following two aspects can be considered:

[0084] find the white list containing the latest ball-putting frequency point, and filter out the ball-putting stations with a distance less than a first distance threshold from the target ball-putting station; move the latest ball-putting frequency point from the white list of the filtered ball-putting stations to the black list; and / or;

[0085] find the ball-putting stations with a distance less than a first distance threshold from the target ball-putting station, and filter out the ball-putting stations with an interval less than a first frequency threshold between the ball-putting frequency point and the latest ball-putting frequency point of the target ball-putting station, move the ball-putting frequency point of the filtered ball-putting stations from the white list of the target ball-putting station to the black list, and move the latest ball-putting frequency point of the target ball-putting station from the white list of the filtered ball-putting stations to the black list.

[0086] Step 112: Find whether there is a temporary frequency point in the white list corresponding to the target ball-putting station.

[0087] The temporary frequency point is a frequency point generated based on a preset frequency range with a second frequency threshold as an interval. If there is, step 114 is performed, otherwise, step 116 is performed.

[0088] When the 24 frequency points of the backup frequency point and the main frequency point cannot meet the assignment, it is found whether there is a temporary frequency point recorded in the white list. The temporary frequency point is a frequency point generated with an interval of 0.025 MHz within 400.15 MHz ~ 406.00 MHz. It should be understood that any frequency point that can be written into the white list must be a usable frequency point, that is, it meets the interference constraint condition of the usable frequency point.

[0089] Step 114: Assign the found one temporary frequency point to the target ball-putting station as the latest ball-putting frequency point, and update the white list of the corresponding ball-putting station.

[0090] In this step, as long as one temporary frequency point is found, the temporary frequency point is assigned to the target ball-putting station as the latest ball-putting frequency point of the target ball-putting station. At the same time, the white list of the corresponding ball-putting station is updated, that is, the occupation state of the backup frequency point is updated. Specifically, the following two aspects can be considered:

[0091] finding a whitelist containing the latest ball release frequency point, and screening out ball release stations with a distance less than a first distance threshold from the target ball release station; moving the latest ball release frequency point from the whitelist of the screened out ball release stations to a blacklist; and / or;

[0092] finding ball release stations with a distance less than a first distance threshold from the target ball release station, and screening out ball release stations with an interval less than a first frequency threshold between the latest ball release frequency point of the target ball release station and the ball release frequency point of the screened out ball release stations, moving the ball release frequency point of the screened out ball release stations from the whitelist of the target ball release station to a blacklist, and moving the latest ball release frequency point of the target ball release station from the whitelist of the screened out ball release stations to the blacklist.

[0093] Step 116: end the current ball release operation of the target ball release station.

[0094] Generally, through the above-mentioned dynamic allocation frequency point scheme, a latest ball release frequency point can be allocated for the target ball release station of the ball release operation, and unless special circumstances, it will not be able to find and allocate.

[0095] Optionally, after the target ball release station completes the ball release operation based on the latest ball release frequency point, the whitelist of the corresponding ball release station can also be updated, and the initial ball release frequency point of the target ball release station can be restored. That is, after the ball release operation is completed, the target ball release station releases the occupation of the current ball release frequency point and restores the initial ball release frequency point.

[0096] Optionally, the preset frequency range is 400.15MHz-406.00MHz; and the second frequency threshold is 0.025MHz.

[0097] Compared with the single ball service mode (ascending section), the double ball service mode (ascending-plateau-descending section data) has a long time and space span, and the balloon may float out of the original receiving range, resulting in that the original relay receiver cannot receive the sounding data of the double balloon (i.e. the sonde). In order to solve this potential problem and ensure stable and effective reception of data, the frequency point of the double ball receiving channel of the nearest relay receiver within the second distance threshold is modified as the receiving frequency point of the plateau double balloon after the ball release, and a stable data reception is performed. Here, the relay receiver can be understood as a satellite navigation sounding receiver. The receiving frequency point of the plateau double balloon can be the real-time frequency point of the sonde.

[0098] Referring to Figure 2 Fig. 1 shows a step schematic diagram of the frequency point dynamic allocation method of the double ball ball release service provided by the present application. When the ball release station has a double ball plateau sounding observation operation requirement, the method mainly includes the following steps:

[0099] Step 202: Determine the flat float double balloon sounding information of all target ball launching stations performing flat float sounding observation operation.

[0100] In the scheme of the present application, the double balloon sounding instrument ID and all relay receiver information can be stored through MySQL, so that the flat float double balloon sounding information can be obtained through the connected MySQL database.

[0101] Step 204: Obtain real-time second data information of each flat float double balloon sounding information according to the corresponding double balloon flat float, wherein the real-time second data information includes time, latitude and longitude, and receiving frequency point.

[0102] Specifically, based on the flat float double balloon sounding information, Redis operation and API request can be used to capture the real-time second data information of the double balloon flat float, i.e. sounding data, through try-except. The real-time second data information is updated in a distributed manner using Redis database.

[0103] Step 206: Based on the time and latitude and longitude in the real-time second data information of each flat float double balloon, periodically find the closest relay receiver within a second distance threshold value radius centered on the flat float double balloon.

[0104] In specific implementation, the position of the flat float double balloon can be determined according to the time and latitude and longitude in the real-time second data information of the flat float double balloon, and then every 10 minutes, the closest two available relay receivers within a 200km radius centered on the flat float double balloon can be found. It should be understood that the period of 10 minutes here is only an optimal example, and the second distance threshold value of 200 is also only an optimal example, which can be flexibly adjusted according to business requirements.

[0105] Optionally, if the relay receivers found for different flat float double balloons are repeated, for each flat float double balloon: all relay receivers within a second distance threshold value radius centered on each flat float double balloon can be periodically found; the closest relay receiver for each flat float double balloon can be re-determined in order from fewest to most of the number of relay receivers found for each flat float double balloon to achieve allocation; wherein each double balloon receiving channel of each relay receiver can only be allocated one receiving frequency point. Thus, it can be ensured that the double balloon with fewer relay receivers occupies the nearest available relay receiver first.

[0106] Step 208: Assign the receiving frequency point to the double balloon receiving channel of the found relay receiver, so that each flat float double balloon can still send sounding data to the re-allocated relay receiver after floating out of the predetermined receiving range.

[0107] In the scheme, the dual-ball receiving channel of the relay receiver can be a 7-channel or an 8-channel. When the 7-channel of any relay receiver is occupied, the corresponding receiving frequency point can also be allocated to the 8-channel of the relay receiver. Therefore, through the above manner, the position and frequency point data of the sounding ball can be acquired in real time, the state information of the relay receiver is combined, the nearest available relay receiver channel is dynamically allocated, and the frequency point matching of the dual-ball sounding ball is ensured.

[0108] From the above scheme, the frequency point dynamic allocation scheme in the ball release service can mainly include three aspects, as shown in Figure 3a and Figure 3b , which are frequency point monitoring, frequency point dynamic allocation of the ball release operation, and frequency point dynamic allocation of the flat floating dual-ball operation (i.e., the above dual-ball flat floating sounding observation operation). As shown in the flowchart of Figure 3a , first, the frequency point monitoring of all frequency points is started, then the frequency point dynamic allocation of the ball release operation is performed in the case of the ball release operation, and finally the frequency point dynamic allocation of the flat floating dual-ball operation is performed. Alternatively, as shown in the flowchart of Figure 3b , first, the frequency point monitoring of all frequency points is started, then the frequency point dynamic allocation of the flat floating dual-ball operation is performed, and finally the frequency point dynamic allocation of the ball release operation is performed.
