摘要
针对传统的水深测量方法,以STC11F04单片机为核心,微弱桥式信号经过A/D转换后送到单片机中,由串口调试工具接收当前测量深度值。重点分析了A/D转换部分对整个系统的影响,合适的高精度的A/D芯片极大提高了精度。实验结果表明,系统电路简单,准确性高,稳定性强,适用于多种测量场合。
One method of depth measuring is designed with the STCllF04 which is taken as the core. The value of the pressure sensor can be handled by the microcontroller after A/D conversion, and users can re- ceive the value of water depth through the serial port debug tool. The influence of A/D conversion can be analyzed in the paper. The precision of the system is improved by the appropriate and high-precision A/D chip. Experiments showed that the system can be used in different occasions because of the simple circuits, high pl：ecision and strong stability.
