Embodiment 1

[0043] This embodiment provides a satellite stand-alone simulation system 30, such as figure 1 As shown, the satellite stand-alone or satellite stand-alone simulation system 30 is connected with the on-board software 10 through the peripheral interface 20, so that the on-board software 10 reads the data of the satellite stand-alone and sends instructions to it, and the satellite stand-alone and the power subsystem 40 is connected with the energy subsystem 50 and collects the data of the subsystem and sends data to it. The satellite stand-alone simulation system 30 simulates a satellite stand-alone for modeling, and the satellite stand-alone includes a sensor 31 and an actuator 32. The satellite stand-alone simulation The system 30 models the satellite stand-alone as a data read operation or write data operation, and performs corresponding data processing according to the algorithm set by the instruction; figure 2 As shown, the satellite stand-alone simulation system 30 includ...

Embodiment 2

[0049] This embodiment provides a satellite stand-alone simulation method based on the satellite stand-alone simulation system 30 described in the previous embodiment, which separates the command action of the satellite stand-alone machine from the command value, and stores the command value in the configuration file 33 Among them, because the same functional command of the same satellite stand-alone machine, its command value is often different, so it is necessary to make all the command values ​​of the satellite stand-alone machine into a configuration file that can be configured, and the command action is solidified into a specific code and stored in the encoding unit 35. The configuration file 33 initializes the configurable unit 34 . If the same stand-alone has different implementation methods for the same command, multiple stand-alone models should be built correspondingly, and the corresponding stand-alone model should be selected according to the actual situation of the...

Abstract

The invention provides a satellite stand-alone simulation system and method. The satellite stand-alone simulation system is disclosed. The satellite stand-alone simulation system is connected with on-satellite software, a power subsystem and an energy subsystem. The satellite stand-alone simulation system simulates a satellite stand-alone for modeling. The satellite stand-alone comprises a sensorand an actuator. The satellite stand-alone simulation system models the satellite stand-alone as data reading operation or data writing operation. And corresponding data processing is performed according to an algorithm set by an instruction. The satellite stand-alone simulation system comprises a configurable unit, a coding unit and a configuration file. A design parameter and generated data in the configurable unit are initialized according to the configuration file. An instruction action in the coding unit is fixed as a function through a code, and the function sends, receives or processesthe generated data.

Description

technical field [0001] The invention relates to the technical field of satellite simulation, in particular to a satellite stand-alone simulation system and method. Background technique [0002] With the rapid development of information technology and space technology, the complexity and new technology content of satellites continue to increase, the development cycle is further shortened, and the requirements for on-orbit life and reliability are higher, making satellite development more and more difficult. Both national economic construction and national defense construction have put forward higher requirements for the research and development of satellites. In order to meet the needs of the country and users for space technology, support the construction of the national economy, and support the accelerated transformation of national defense to informatization, my country's aerospace industry sector is facing the challenges of tight schedules, heavy tasks, and complex techno...
