摘要
为解决某型卫星信息采集系统中陀螺组合数据等的实时通讯问题,提出了利用CAN总线实现整个信息采集系统设计。与一般信息采集系统相比,该系统下位机采用TMS320F2812型DSP,利用其eCAN模块作为数据发送模块,上位机采用工控机,其中ADLINK PCI/cPCI-7841 CAN总线接口卡作为数据接收模块,并在工控机中实时处理接收到的数据,更可靠地完成了信息采集及实时监测。实验结果表明,该系统信息采集实时性强、准确稳定。
In order to solve the real-time communication problem of a certain type satellite＇s information acquisition system, an information acquisition system design was achieved by using CAN bus. Comparing with other information acquisition systems, in this system the eCAN module which was on the wpper machine the TMS320F2812DSP was used as data sending module, and ADLINK PCI/cPCI-7841CAN interface card which was on the upper machine industrial personal computer was used as data receiving module. And the receiving data were handled in the industrial personal computer. It is more reliable to accomplish the information acquisition and real-time monitoring. The information acquisition system is stable and real-time by experiment verification.
