基于PIC单片机的谷物容重测量系统设计

Design of Cereal Bulk Density Measurement System Based on PIC

介绍了由PIC单片机控制的谷物容重测量系统,此系统通过称重传感器将谷物的质量信号转化为电压模拟信号,经同相放大电路和A/D转换接入单片机,然后读出相应的质量值,进行计算即可得到相应的容重值。其中的关键技术包括A/D转换、单片机主控程序等。

This text introduces the cereal bulk density measurement system controlled by the PIC, the system turn the quality signal of the grain into the analog signal of the voltage with the weigh sensor, through with enlarge circuit and A/D change and insert the single chip, then read corresponding quality value, can receive corresponding unit weight value to calculate while going on. The key technologies include： A/D change, single chip control procedure and so on.
