Problems solved by technology

At present, it is all done by sending indirect commands multiple times on the ground. The existing indirect commands are injected one by one, which takes a long time and requires a lot of manpower and channel resources, which brings certain risks to the normal execution of tasks.

Embodiment Construction

[0012] The specific implementation of a multi-task-based satellite command sequence processing method and device provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] see figure 1 As shown, a multi-task-based satellite command sequence processing method includes the following steps: S11: Obtain all indirect commands required for remote command tasks; S12: Pack all indirect commands into corresponding A number of injected data forms an instruction sequence, wherein the instruction sequence includes at least one instruction task; S13: Send all the injected data in the instruction sequence. The following is a detailed description of the above steps.

[0014] S11: Obtain all indirect commands required by the remote control command task.

[0015] After analysis, the commands required for satellite remote control command tasks are all indirect commands. If the indirect commands are encapsulated into the format o...

Abstract

A method and device for processing satellite command sequences based on multitasking, the method includes the following steps: (1) acquiring all indirect commands required for remote control command tasks; (2) converting all indirect commands according to the maximum package value of each piece of injected data Instructions are encapsulated into a corresponding number of injected data formats to form an instruction sequence, wherein the instruction sequence includes at least one instruction task; (3) sending all the injected data in the instruction sequence. The invention greatly reduces the number of ground operations, simplifies the operation process, reduces human error in operation, and effectively improves the reliability, safety and ease of use of remote control operations; at the same time, it reduces the ground operation time and reduces the resource occupancy rate of remote control. Improved remote control efficiency.

Description

technical field [0001] The invention relates to the technical field of aerospace measurement and control, in particular to a high-efficiency ground-to-spacecraft program control method and device based on multi-task satellite command sequence processing. Background technique [0002] There are generally two ways of ground-to-spacecraft program control: indirect command mode and data injection mode. The length of the indirect instruction is relatively short, and the length of its data field is dozens of bytes. It is mainly some control instructions such as stand-alone or software state switching, parameter setting, etc.; the processing of indirect instructions includes: generation, application for sending, sending, and judging the execution status. Multiple people are required to participate in multiple operations, and the processing of each indirect instruction takes at least 6 seconds. The length of the injected data is relatively long, and the length of the data field is ...
