[0002] With the increasing demand for communications in modern society, especially in emergencies or emergencies, emergency communications have become a key technology to ensure the smooth progress of rescue operations. In scenarios such as natural disasters, military operations, and public safety, traditional ground communication networks often fail due to infrastructure damage or excessive network load. At this time, multi-mode converged communication technology based on satellite communications, Beidou short messages, ad hoc networks, and mobile networks can provide strong support for emergency communications.

[0003] However, most of the existing emergency communication switching methods are based on a single communication parameter, such as signal strength or delay, and it is difficult to effectively select the optimal communication method under energy constraints.

In addition, some or all of the modules may be selected according to actual needs to achieve the purpose of the present application.

[0039] Please refer to Figure 1 The data communication transmission method based on Beidou satellite provided by the present invention includes:

[0040] S101: Obtain basic parameter data of the communication network, and obtain the remaining energy of the current Beidou satellite and the transmission demand of the current data to be transmitted;

[0041] In the present invention, the basic parameter data includes information such as signal strength, bandwidth, and delay of the communication network. Generally, Beidou satellites obtain and store electrical energy through solar energy. The present invention requires real-time monitoring of the energy of the remaining power of the entire Beidou satellite at that time.

[0042] S102: Determine the urgency of the data to be transmitted, establish a transmission mode evaluation model, and obtain an evaluation value according to basic parameter data, urgency, remaining energy and transmission demand through the transmission mode evaluation model;

[0043] In this embodiment, the urgency of the data to be transmitted is taken into consideration, and the urgency of the data can significantly improve the transmission efficiency and resource utilization. First, the priority transmission of urgent data can ensure the real-time nature of key services, reduce delays, and avoid losses caused by delayed data processing. It can help relevant parties respond quickly.

[0044] Secondly, giving priority to urgent data helps to reasonably allocate network bandwidth and computing resources and avoid wasting resources. For example, when the network is congested, the priority of urgent data can be sorted to ensure effective distinction between important information and non-urgent information, thereby improving overall transmission efficiency.

[0045] In addition, the consideration of urgency also enhances the intelligence and automation level of data transmission, allowing the system to dynamically adjust strategies and optimize the transmission process, thereby improving user experience. Therefore, considering the urgency of data has important practical significance and application value in the management of data to be transmitted.

[0046] S103: Setting an evaluation value threshold. If the evaluation value is greater than the evaluation value threshold, selecting a first transmission mode to transmit the data to be transmitted. If the evaluation value is not greater than the evaluation value threshold, selecting a second transmission mode to transmit the data to be transmitted. The energy consumption of the second transmission mode is lower than that of the first transmission mode, and the rate of the second transmission mode is lower than that of the first transmission mode.

[0047] The method provided by the present invention mainly includes obtaining basic parameter data of the communication network, obtaining the remaining energy of the current Beidou satellite and the transmission demand of the current data to be transmitted; establishing a transmission mode evaluation model, setting an evaluation value threshold, if the evaluation value is greater than the evaluation value threshold, selecting the first transmission mode to transmit the data to be transmitted, if the evaluation value is not greater than the evaluation value threshold, selecting the second transmission mode to transmit the data to be transmitted, the energy consumption of the second transmission mode is lower than the first transmission mode, and the rate of the second transmission mode is lower than the first transmission mode. Through this method, energy consumption is taken as the core consideration factor of communication switching. In the case of insufficient energy of the device, a low-energy consumption communication mode is preferentially selected to extend the working time of the device. By analyzing the data transmission demand, it is ensured that the appropriate bandwidth is selected when the data volume is small to avoid bandwidth waste; when large-capacity transmission is required, a high-bandwidth network is preferentially selected to ensure communication efficiency. It can adaptively adjust the switching strategy according to the real-time changing network status, equipment resources and task requirements to ensure the provision of stable and efficient communication services in complex emergency scenarios.

[0048] In an exemplary embodiment of the present invention, determining the urgency of the current data to be transmitted includes:

[0049] Obtaining a transmission instruction from the requesting end, wherein the transmission instruction includes ordinary transmission, general emergency, and special emergency;

[0050] If the received transmission instruction is a normal transmission or a general emergency, the transmission demand of the data to be transmitted is obtained, an urgency judgment model is established, and a judgment value is output through the urgency judgment model;

[0051] A judgment value threshold is set. If the judgment value is greater than the judgment value threshold, the current transmission instruction is upgraded by one level. If the judgment value is not greater than the judgment value threshold, the current transmission instruction is maintained.

[0052] In an exemplary embodiment of the present invention, the urgency determination model includes:

[0053]

[0054] In the formula, is the judgment value, The time sent by the requesting end to the BeiDou satellite. is the transmission demand of the data to be transmitted, is the transmission channel size.

[0055] In this embodiment, the transmission channel is taken into consideration. If the transmission channel is larger, more messages can be transmitted at this time, and data with a higher degree of urgency can be sent out faster, so the judgment value is reduced.

[0056] Specifically, setting the judgment value threshold includes:

[0057]

[0058] In the formula, is the judgment value threshold.

[0059] In an exemplary embodiment of the present invention, the transmission mode evaluation model includes:

[0060]

[0061] In the formula, is the signal strength, is the network bandwidth, For network delay, is the remaining energy of BeiDou satellite, is the transmission demand of the data to be transmitted, To calculate the coefficient, Indicates the urgency of the data to be transmitted. is the number of satellites required for the data transmission to be transmitted, The total reserve energy of Beidou satellite.

[0062] Among them, when the urgency is normal transmission, , when the urgency is general, , when the urgency is extremely urgent,

[0063] Specifically, the evaluation value thresholds include:

[0064] In the formula, is the evaluation value threshold.

[0065] For example, if the signal strength is -30dBm, the network bandwidth is 3 Mbps, the network delay is 0.1ms, the remaining energy of the Beidou satellite is 1 kWh, the transmission demand of the data to be transmitted is 0.4 MB, the urgency is normal transmission, the number of satellites required for the data to be transmitted is 2, and the total reserve energy of the Beidou satellite is 2.8 kWh, then we can get , Therefore, the first transmission method can be used for data transmission. Through the above content, there are more choices for communication transmission methods, and through the above content, when choosing which method to transmit, a suitable communication transmission method can be selected more accurately.

[0066] In a second aspect, the present invention further provides a data communication transmission system based on Beidou satellite, comprising:

[0068] A selection module is configured to set an evaluation value threshold, and if the evaluation value is greater than the evaluation value threshold, select a first transmission mode to transmit the data to be transmitted, and if the evaluation value is not greater than the evaluation value threshold, select a second transmission mode to transmit the data to be transmitted, wherein the energy consumption of the second transmission mode is lower than that of the first transmission mode, and the rate of the second transmission mode is lower than that of the first transmission mode;

[0069] The main control module is connected to the acquisition module and the selection module, and is used to execute the above-mentioned Beidou satellite-based data communication transmission method.

The above-mentioned integrated unit may be implemented in the form of hardware or in the form of software functional units.
