[文章/文档] CPLD

针对超声波应用系统易受噪声干扰以及超声波信号的空间衰减现象影响, 从而要求 超声波传感器工作在其最佳特性的特点, 论证了驱动脉冲信号的控制精度对传感器工作特 性的影响, 给出了传感器驱动信号脉冲宽度与传感器频率之间的最佳关系式, 提出了采用复 杂可编程逻辑器件(CPLD) 产生传感器驱动控制信号的方法, 将该方法应用于一超声波流 量计测量系统中, 得到了比传统型单片机控制电路更好的控制精度和控制效果。
For ultrasonic applications vulnerable to noise interference and attenuation of ultrasonic signals in the effects of space and thus require ultrasonic sensors work best features in its characteristics, demonstrated that the drive pulse signal of the control accuracy of the sensor characteristics of the work, given the sensor-driven signal pulse width and frequency sensors of the best relationship between the proposed use of complex programmable logic device (CPLD) have a sensor-driven control signal approach, the method is applied to one ultrasonic flowmeter measurement system has been more than traditional single-chip control circuit better control precision and control.
