摘要
液压泵瞬态特性的测量控制直接关系到液压传动系统的控制性能,基于DSP芯片嵌入式系统能够满足对液压泵工作特性参量的实时采集和信号处理的需求。论文分析设计了基于DSP芯片的液压泵(压力、扭矩、转速)的采集硬件模块和外围电路,编制系统各功能模块的测试软件。经实际运行,证明该系统能够对液压试验台的各个参数进行准确的采集。
Measurement and control of transient behavior performance for hydraulic pump is critical to hydraulic control system. Embedded System based on DSP chip can satisfy the demand of real-time collection and signal processing for hydraulic pump operating parameters. The collecting hardware module and peripheral circuit of hydraulic pump based on DSP chip were designed. The function of system was to acquire all kinds of physical quantity including pressure, torque, and rotating speed. And the software of relative function modules was devised and finished. At last, the whole system was operated and tested. The results prove that the system realizes the proposed target, and could acquire all kinds of physical quantity of hydraulic test bed.
