Description

A general method for optimizing information transmission Technical Field

[0001] This invention belongs to the field of information sharing technology, and in particular relates to a general information transmission optimization method. Background Technology

[0002] In emergency rescue missions, supplies need to be airdropped. Ground weather factors need to be considered during the rescue process. In order to obtain more accurate and complete ground weather observation information, meteorological teams are usually dispatched to important target points in the mission area to obtain real-time weather data and transmit the data through satellite communication, thereby ensuring the smooth completion of the rescue mission.

[0003] The speed of meteorological satellite message transmission is a key factor affecting the dispatch of meteorological satellite rescue teams. Even with negligible time spent sending and receiving messages at each observation station, information sharing of meteorological messages via satellite communication equipment ensures that meteorological information collected by any one observation station is successfully forwarded to all other observation stations. This information sharing plays a crucial role in emergency rescue. Meteorological information sharing can provide a more efficient basis for meteorological monitoring, early warning, and decision-making. Currently, information sharing mainly relies on network transmission models and intelligent algorithm simulations to demonstrate transmission methods. While these methods offer good transmission results for specific problems, their scalability is insufficient. Research on general information sharing optimization algorithms supported by mathematical theory is limited; therefore, a general information transmission optimization method based on rigorous logical reasoning is urgently needed. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides a general information transmission optimization method, comprising the following steps:

[0007] Within the first minute of message transmission, from minute 0 to minute (N / 2)-1 or ((N-1) / 2)-1, N satellite communication stations shall perform forward transmission;

[0008] During the (N / 2)-1 or ((N-1) / 2)-1 minute to the (N / 2)+[(N / 2)-1] or ((N-1) / 2)+[(N-1) / 2)-1] minute of message transmission, the N satellite communication stations perform reverse transmission in reverse order;

[0009] Under the cyclical recursion of the forward information transmission and the reverse reverse transmission, a signal transmission model is obtained, and information transmission is optimized based on the signal transmission model.

[0010] Optionally, during the forward transmission process of the N satellite communication stations, the transmission direction of the message is:

[0011] During the transmission from the 1st station to the Nth station, the data is sent from the (i-1)th station to the 1st station; the next station after the Nth station is taken as the 1st station; where i is an integer greater than 1 and less than N.

[0012] Optionally, the process of enabling the N satellite communication stations to perform forward transmission includes:

[0013] During the process from minute 0 to minute (N / 2)-1 or (N-1) / 2-1, starting from minute x, the iy-th station transmits its own message content to the i-th station; where x is greater than or equal to 0 and less than or equal to (N / 2)-1 or (N-1) / 2-1, and x = y-1.

[0014] Optionally, during the reverse transmission process among the N satellite communication stations, the transmission direction of the messages is:

[0015] During the transmission from the 1st station to the Nth station, the data is sent from the (i-1)th station to the 1st station; the station preceding the Nth station is taken as the 1st station.

[0034] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0035] Example 1

[0036] As shown in Figure 1-10, this embodiment provides a general information transmission optimization method to study the information sharing of meteorological reports among the main stations of N detachments. The main focus is on minimizing the time K required for this information sharing. This problem is commonly referred to as the signal transmission optimization problem. In this information transmission optimization problem, each satellite communication device can only send one message at a time, and the time interval between sending two messages cannot be less than one minute. The sending and receiving channels are independent, and multiple messages can be received simultaneously while a message is being sent. The time for sending and receiving messages is very short; here, we assume the time interval between two messages is one minute, and the time for sending and receiving messages is not counted.

[0037] A general information transmission optimization algorithm is presented, providing a general mathematical model for the minimum value K required for information sharing of meteorological reports among N branch stations, an algorithm for implementing information sharing, and a graphical representation of the information sharing process. A general mathematical model for information transmission and sharing is provided, which can be applied to information transmission and sharing in other fields.

[0038] During satellite information transmission, the station (master station) is numbered 1, 2, 3, 4, ... i ... N, (N>=5).

[0039] The first stage: Forward sequential information transmission

[0040] Forward transmission: station i-1 (i>1) transmits information to station i, and station 1 receives the message from station N. Forward sequential information transmission is shown in Figure 1.

[0041] The transmission begins at minute 0.

[0042] In the initial state (minute 0), station i-1 transmits its own message content. (Message transmission direction: from the previous station (i-1) (i>1) to this station (i), and station 1 receives the message from station N.)

[0043] In the first minute, the message content i-2 is transmitted, containing the message content of its own station (in the direction of message transmission).

[0044] In the second minute, the message content i-3, belonging to its own site, is transmitted (in the direction of message transmission).

[0045] Until the (N / 2)-1 or ((N-1) / 2)-1 minute (when N is even, choose (N / 2)-1 for calculation, when N is odd, choose (N-1) / 2)-1 for calculation), transmit the message content i-(N / 2 or (N-1) / 2) of its own site's message content.

[0046] Phase Two: Reverse Information Transmission

[0047] Starting at minute (N / 2) or ((N-1) / 2), the transmission direction changes, and information is transmitted in reverse.

[0048] Station i+1 (i>1) transmits information to station i, and station 1 sends a message to station N. The reverse information transmission is shown in Figure 2.

[0049] At the (N / 2) or ((N-1) / 2) minute, the message content i+1 (i>1) of the station's own message content is transmitted.

[0050] At the (N / 2)+1 or ((N-1) / 2)+1 minute, the message content i+2 (i>1) of the station's own message content is transmitted.

[0051] At (N / 2)+2 or ((N-1) / 2)+2 minutes, the message content of station i+3 (i>1) is transmitted, and the message content of station i+3 (i>1) is transmitted in a recursive loop.

[0052] Until the (N / 2)+[(N / 2)-1] or ((N-1) / 2)+[(N-1) / 2)-1] minute (when N is even, choose (N / 2)+[(N / 2)-1] for calculation; when N is odd, choose ((N-1) / 2)+[(N-1) / 2)-1] for calculation), transmit the message content i+(N / 2 or (N-1) / 2) of its own site's message content.

[0053] Under this recursive propagation method, the following general signal transmission model is derived:

[0054]

[0055] Based on the model, with N=9, the minimum value of K is calculated to be 7 minutes. The specific transmission process is then described using this model and illustrated with a process diagram.

[0056] As shown in Figure 3, at t = 0 minutes (since the time for sending and receiving messages is negligible), the message content of station i-1 is transmitted in the forward order: the message transmission direction is from the previous station (i-1) (i>1) to this station (i), and station 1 receives the message message from station 9.

[0057] As shown in Figure 4, at t = 1 minute, the message content of station i-2 is transmitted in the forward sequential direction.

[0058] As shown in Figure 5, at t = 2 minutes, the message content of its own site owned by the transmitted message content i-3 is transmitted in a forward sequential manner.

[0059] As shown in Figure 6, at t = 3 minutes, the message content of its own site owned by the transmitted message content i-4 is transmitted in a forward sequential manner.

[0060] As shown in Figure 7, at t = 4 minutes, the message content of its own site owned by the transmitted message content i+1 site. The message transmission direction is reverse sequential transmission: from the next site (i+1) ((0 <= i <= 8)) to the current site (i), and the 9th site receives the message from the 1st site.

[0061] As shown in Figure 8, at t = 5 minutes, the message content of its own site owned by the transmitted message content i+2 site is transmitted in a reverse sequential manner.

[0062] As shown in Figure 9, at t = 6 minutes, the message content of its own site owned by the transmitted message content i+3 site is transmitted to the i-th site, and the transmission method is reverse sequential transmission.

[0063] As shown in Figure 10, at t = 7 minutes, the message content of its own site owned by the transmitted message content i+4 site is transmitted to the i-th site, and the transmission method is reverse sequential transmission.

[0064] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
