| 摘 要： | 建立了用于液位测量的CCD摄像测量系统。在散射照明的条件下,液位图像成像到高分辨力的电荷耦合器件上,然后通过对传感器信号进行分析和处理,可以精确地计算出液位的高低。利用CCD摄像法实现液位精确测量,处理电路采用C8051F060单片机为核心器件对传感器输出信号进行处理,通过单片机串口将采集的数据传输给计算机。系统具有非接触、实时性、高准确度以及自动化的特点。

| Abstract: | Based on the theory of photography, a CCD measurement system with high accuracy was constructed to measure the liquid level in glassy cylinder. The signal from CCD was sampled by a 16-bits Analog-Digital Conventer inside the Single Chip Machine which also processes the signal. The results of measurement experiments show that this system is accurate enough to measure the liquid level, and it is non-contact and on-time. |
