After the altimeter determines that the specified altitude has been reached, the weather balloon stays in the high altitude and transmits the data back, and the platform lands at high speed through the high-altitude gliding variable structure aircraft. After reaching the predetermined altitude, the tail wing is rotated, and the worm gear is driven to rotate automatically by the steering gear, the flight mode of the aircraft is changed, and the short wing is used as the fuselage for gliding. And in the near-ground gliding interval, small-scale meteorological information is collected to realize multi-scale meteorological information collection.

Especially in harsh environments, communication quality is unstable, resulting in data loss. Insufficient utilization of bandwidth resources: Traditional methods generally use a fixed data transmission cycle, which cannot be dynamically adjusted according to the real-time network bandwidth conditions, resulting in inefficient utilization of bandwidth and affecting the real-time and accuracy of data transmission; Lack of disaster level judgment and emergency data priority transmission mechanism: Most existing technologies use a static feedback mechanism, without automatic judgment and dynamic adjustment of disaster data priority, and cannot meet the demand for rapid feedback of disaster data in emergency situations.

DETAILED DESCRIPTION
[0019] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations on the technical solution of the present invention. The embodiments of the present invention and the technical features in the embodiments may be combined with each other unless there is a conflict.
[0020] The term "and / or" is merely a description of the association relationship between associated objects, indicating that three possible relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone.
[0021] Figure 1 A flowchart of a method for remote data transmission of an automatic weather station in an unmanned area disclosed in this embodiment is shown, and the steps are as follows: S1, collect temperature, humidity, air pressure and wind speed data monitored by the weather station to generate multi-type meteorological data sets; S2. Combining the multiple types of meteorological data sets with a signal quality monitoring strategy to obtain a signal quality score; The signal quality monitoring strategy includes calculating the meteorological environment impact value through the multi-type meteorological data set, and obtaining it by weighted summing the real-time signal strength and signal packet loss rate after standardization with the meteorological environment impact value. The meteorological environment impact value is obtained by weighted summing the humidity impact value, the temperature impact value, the air pressure impact value and the wind speed impact value. The change in temperature will affect the propagation of electromagnetic waves. Usually at higher temperatures, the conductivity of the air increases, resulting in increased signal attenuation. To this end, this embodiment uses a function based on temperature difference to represent the impact of temperature on signal quality. This impact usually decreases with increasing temperature, so we use a function containing the square difference of temperature to represent its negative impact on signal quality.
[0022] In a high humidity environment, the moisture content in the air increases, which will cause attenuation of radio wave propagation, especially in high-frequency signals. The effect of humidity on signal quality is usually negative, and as humidity increases, signal quality gradually decreases. This embodiment uses an exponential decay function to represent the effect of humidity on signal quality.
[0023] Changes in air pressure affect the density of the air, and thus affect the propagation efficiency of radio waves. When the air pressure is low, the air density is low, and the signal propagation effect is also poor. This embodiment uses a function that is linearly related to the change in air pressure to represent the negative impact of air pressure on signal quality.
[0024] Wind speed affects signal quality mainly by affecting the multipath propagation effect of the signal (such as reflection, refraction, etc.). A large wind speed may cause signal instability and signal attenuation. In order to reflect the impact of wind speed on signal quality, this embodiment uses a linear function to represent the negative impact of wind speed.
[0025] Therefore, the temperature influence value calculation formula is: , the calculation formula of humidity impact value is: 、The calculation formula of air pressure influence value is: The calculation formula of wind speed influence value is: ,in, represents the temperature influence coefficient, represents the humidity influence coefficient, represents the air pressure influence coefficient, represents the wind speed influence coefficient, represents the reference temperature, represents standard air pressure, T represents real-time temperature, H represents real-time humidity, P represents real-time air pressure, and W represents real-time wind speed.
[0026] Set a minimum signal quality value, extract meteorological data whose signal quality score is less than or equal to the minimum signal quality value, list them in the meteorological data to be distributed, and send them to step S3; extract meteorological data whose signal quality score is greater than the minimum signal quality value, list them in the meteorological data to be transmitted, and send them to step S5; S3, through the priority evaluation algorithm, obtain the meteorological importance index of all data to be allocated and form a priority queue; The priority evaluation algorithm includes combining all meteorological data with weighted coefficients according to the current disaster level and meteorological data reliability index to obtain the priority level of all meteorological data and list them in the priority data set. , Indicates the Nth meteorological data, N indicates the number of meteorological data, and all meteorological data are listed in the priority queue in descending order of priority.
[0027] The priority evaluation algorithm also includes judging the disaster level of the current meteorological data through a disaster level prediction model based on the current multi-type meteorological data set, wherein the disaster level prediction model collects historical meteorological data and corresponding ratings as model training data, inputs the current multi-type meteorological data set, and obtains the current disaster level; and evaluating the reliability index of the current meteorological data based on the deviation between the historical meteorological data and the actual observation value, wherein the reliability index of the current meteorological data is expressed as: ,in, represents the adjustment coefficient, Represents the root mean square error between current meteorological data and historical meteorological data.
[0028] S4, setting a hierarchical return strategy for meteorological data, and allocating a transmission period for all data to be allocated according to the priority queue; Figure 2 A flowchart of a meteorological data hierarchical return strategy for a remote data return method of an automatic weather station in an unmanned area disclosed in this embodiment is shown. The specific steps of the meteorological data hierarchical return strategy include: S41, divide the priority queue into three return levels, including high priority data, medium priority data and low priority data, and allocate an initial return cycle for each level; S42. In order to improve bandwidth utilization and reduce communication costs, an incremental backhaul strategy is set. During each transmission, a new priority level is calculated based on incremental data, and the backhaul level is reallocated. S43, allocating the number of broadbands according to the priority ratio of each meteorological data; S44. After each return transmission, the receiving platform generates a feedback report based on the actual transmission value and updates the return transmission period through a period dynamic adjustment algorithm.
[0029] During the transmission process, the priority queue changes dynamically. According to the real-time meteorological data changes, the disaster level changes or the actual bandwidth situation, the system should continuously adjust the priority queue. After each data transmission, the priority of all meteorological data is re-evaluated and the priority queue is updated.
[0030] The incremental return strategy tracks the absolute value of meteorological data changes within the time TT, sets a change threshold, extracts meteorological data whose absolute value of meteorological data changes is greater than the change threshold, and combines the disaster level, meteorological data reliability index and the weighted average of the absolute value of meteorological data changes after standardization to obtain a new priority level; adds it to the allocation result of step S41, for example, there is a new priority level greater than the intermediate priority level data. , the data will be changed to high priority data.
[0031] The period dynamic adjustment algorithm includes calculating the transmission evaluation value of meteorological data, and the transmission evaluation value is obtained by extracting the actual transmission value to generate the transmission success rate tsr, transmission delay trd and bandwidth utilization bau in the feedback report. The transmission evaluation value calculation formula of the i-th data is: ,in , and represents the weight coefficient; then the update formula for the i-th data return period is: ,in, Indicates the initial return cycle, which is the basic cycle set according to the data priority (for example, 1 hour for high priority data and 2 hours for low priority data). and represents the adjustment coefficient, .
[0032] because Reflects the data transmission quality. The higher the value, the better the transmission quality. The smaller it is, the longer the return cycle will be; conversely, if the transmission quality is poor, the return cycle will be shortened to increase the frequency of data transmission and avoid data loss.
[0033] For high priority data, The larger the value, the shorter the return cycle. For low priority data, The smaller the value, the longer the return cycle. The value is in the range of [0, 1], and data with higher priority corresponds to larger values.
[0034] Meteorological data with higher priority (such as disaster data) will be assigned a shorter return cycle to ensure that they are returned as soon as possible. Meteorological data with lower priority (such as ordinary weather data) can have a longer return cycle to avoid occupying too much bandwidth resources.
[0035] Priority data is transmitted first: This formula ensures that high-priority data (such as disaster warning data) can be transmitted quickly, while the transmission cycle of low-priority data will be dynamically adjusted according to bandwidth utilization to avoid wasting bandwidth resources.
[0036] Strong adaptability: Combining the impact of transmission quality assessment and data priority, the system can flexibly adjust the return cycle according to different network environments and bandwidth conditions to improve overall transmission efficiency.
[0037] Improve system reliability: Automatically shorten or extend the return cycle according to the data transmission quality, and increase the data transmission frequency when the transmission quality is poor, ensuring the timely transmission and integrity of the data.
[0038] S5. Upload the received data to the receiving platform.
[0039] The threshold and weight can be set by operators in this field.
