LMA-1型低频力学谱仪(LFMS)控制系统硬件布局复杂且调试不方便,由上位机对各部件实现集中控制,系统实时性差.文中结合CAN总线特点,将低频力学谱仪的各部件设计成CAN总线节点,重新构建了低频力学谱仪的控制系统,并提出了硬件设计方案及上位机、下位机软件的设计流程.改进后的系统中,上位机主要完成数据采集与分析任务,各部件由CAN总线节点上的微处理器控制,改善了系统的实时性并节省了计算机硬件资源,使系统今后的优化更为灵活.

The hardware layout of LMA-1 low frequency mechanical spectroscopy (LFMS) control system is very complex and it is difficult to debug the system.The upper computer controls all the parts of the system.So the real time performance is not so good.The control system was rebuilt with CAN bus and all the parts of the original system were transformed into CAN bus nodes.The hardware design and software design flows of the upper computer and the lower computer were given.The upper computer was responsible for DAQ and analysis in the new system and the entire CAN bus nodes were controlled by the respected MCU.With the new design,the real time performance is improved and the hardware resources of the computer are saved and the further optimization becomes much easier.
