Abstract

The invention provides a resource receiving conflict processing method and system of a satellite ground station. The method comprises following steps of searching a corresponding antenna priority list according to the satellite numbers contained in tasks; sequentially searching idle antennas according to the antenna priority list; adding the tasks in the task lists of the idle antennas; searching a corresponding recording device priority list according to the satellite numbers contained in tasks; sequentially searching idle recording devices according to the recording device priority list; and adding the tasks in the task lists of the idle recording devices. According to the scheme, the combination of the resource allocation and the priority strategy is realized through the set priorities of the antenna devices and the recording devices and a device resource conflict detection mode; the priority strategy is applied in the satellite ground system with multiple receiving antennas and multiple recording devices; the satellite ground system with multiple receiving antennas and multiple recording devices can execute multiple satellite data receiving tasks at the same time; and the satellite data receiving capacity and efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of satellite planning and dispatching, and in particular relates to a method and system for processing conflicts of receiving resources of a satellite ground station. Background technique [0002] The satellite ground station mainly includes the antenna feed subsystem, the channel subsystem, the recording subsystem, the monitoring subsystem, the transmission subsystem and the technical support subsystem, etc. In the process of satellite receiving data, the above-mentioned subsystems need to cooperate together to complete tasks such as satellite capture, satellite data reception, recording and transmission. [0003] In the satellite ground system, the operation and control system generally formulates the receiving plan according to the ground station resources, and formulates the receiving antenna and recording equipment. However, the functions of the operation and control system in some satellite ground syst...
