The invention discloses a satellite control method and device based on distributed data acquisition, and belongs to the technical field of satellite control. The method comprises the steps that four computers are used for constructing a control system, each computer is connected to a corresponding lower computer through a bus, the multiple lower computers are dispersed to achieve data collection and control through different computers, and in the control system, each computer collects local data responsible for the computer, and the local data are stored in the control system; the method comprises the following steps of: performing data exchange on local data and other computers to obtain local input data, further performing fusion processing on the local input data, performing control calculation to obtain local output data, and performing exchange comparison on the local output data and the output data of other computers to ensure the reliability of the output data. Therefore, local output control data is obtained, and the lower computer is controlled by using the local output control data. According to the invention, through combination of distributed data acquisition and four-machine hot backup, the real-time performance of data processing can be improved.
本发明公开了一种基于分布式数据采集的卫星控制方法及装置,属于卫星控制技术领域。方法包括:利用四个计算机来构建控制系统,每一个计算机通过总线连接至对应下位机,多个下位机分散开由不同计算机实现数据采集和控制,在控制系统内,每一个计算机均采集自身负责的本机数据,然后将本机数据与其它计算机进行数据交换以得到本机输入数据,进一步对本机输入数据进行融合处理后,以进行控制计算得到本机输出数据,为保证输出数据的可靠性,对本机输出数据与它机输出数据进行交换比对,从而得到本机输出控制数据,利用本机输出控制数据对下位机进行控制。本发明通过分布式数据采集与四机热备份相结合,能够提高数据处理的实时性。
