Description

Multi-beam satellite transmission method, electronic equipment and storage medium Technical Field The disclosure relates to the technical field of satellite communication, and in particular relates to a multi-beam satellite transmission method, electronic equipment and a storage medium. Background The high-throughput satellite (HTS) greatly improves the bandwidth capacity through technologies such as multi-point beam, frequency multiplexing and the like, the total capacity is developed from less than 10Gbps in the first generation to more than 200Gbps in the fourth generation of all-digital beam technology, and basic support is provided for remote transmission of high-definition video streams and other large-bandwidth services. Along with the development of phased array technology, the Ka/Ku frequency band satellite portable station realizes miniaturization, the antenna caliber can be reduced to 0.5m, the satellite portable station also has a one-key automatic satellite finding function, and the portable requirement of scenes such as emergency communication can be met. But is limited by the hardware transmission capability of a single terminal, the uplink rate of the Ka frequency band portable station is only 15Mbps, the downlink rate is only 60Mbps, and the stable transmission requirement of the ultra-high definition video stream is difficult to support. In order to break through the constraint of the upper limit of the single-terminal bandwidth, the prior art tries to improve the total throughput by adopting a multi-beam parallel transmission mode, but the actual application effect is still not ideal, and the core problem is concentrated in the following two aspects: (1) The bandwidth utilization rate is low, the dynamic aggregation capability is insufficient, the prior art mostly adopts a mode of fixed frequency band multiplexing or single beam independent transmission, and the capability of aggregating multi-beam resources in real time is lacking. The scheme allocates the frequency band, the time slot and the transmission load proportion of each wave beam in advance in the link planning stage, and the allocation strategy cannot be dynamically adjusted in the transmission process. In a high dynamic satellite communication environment, factors such as rain fade, atmospheric turbulence and the like can cause random fluctuation of beam signal quality. The traditional load balancing algorithm relies on post-monitoring data for adjustment, response lag is obvious, and resource allocation cannot be optimized in advance according to link state change. This directly results in a bandwidth fluctuation rate as high as 30%, part of the beams are in a high-load congestion state, and the other part of the beams are in a low-load idle state, so that the waste of spectrum resources is serious. The situation is difficult to meet the stable transmission requirements of high-bandwidth services such as high-definition video streaming, large file transmission and the like. (2) The transmission protocol has poor adaptability to satellite multi-beam scenes, and the problems of data packet loss and timing sequence disorder are extremely easy to be caused by the lack of an effective error control and congestion management mechanism in an unreliable network environment with high time delay and high jitter of a satellite link by the traditional transmission protocol (such as UDP). Disclosure of Invention The disclosure provides a multi-beam satellite transmission method, electronic equipment and a storage medium, which are used for solving the problems of low bandwidth utilization rate, insufficient dynamic aggregation capability and poor suitability of a transmission protocol to satellite multi-beam scenes in the existing multi-beam satellite transmission method. In a first aspect, the present disclosure provides a multi-beam satellite transmission method applied to a satellite portable station, the method comprising: Acquiring a link state key index and environment data; Inputting the link state key index and the environment data into an embedded artificial intelligence AI module, and outputting a link score of N seconds in the future, wherein N is more than or equal to 1; And determining the availability judgment result of the link according to the link score, and transmitting the link availability judgment result and the link score to an aggregation router, so that when the aggregation router receives the target service signal coded by the safe and reliable transmission protocol SRT coder, determining the load weight corresponding to each available satellite portable station according to the link availability judgment result and the link score of at least 2 satellite portable stations, and carrying out link aggregation based on the load weights so as to transmit the target service signal. Further, before the obtaining the link state key indicator and the environmental data, the method further includes: when a satellite portab
