智能称重仪表的原理与设计

PRINCIPLE AND DESIGN OF INTELLIGENT WEIGHING INSTRUMENT

运用单片机技术设计而成的智能称重仪表，具有结构简单、性能可靠、称重准确、功能齐全等特点，所采用的模拟输入接口电路仅用一个电阻就能对增益进行准确校正，大大优越于传统的三片运放电路。称重系统的硬件结构合理，软件设计先进，为计算机在电子衡器中的应用提供了良好的范例。

The intelligent weighing instrument designed by use of the single chip computer is characterized by simple structune,reliable performance,accurate weighing and allround functions.What only one resistor was usde for the simulating input interface circuit can make accurate correction for increment,which has great advantage over the conventional three-chip operation amplifying circuit.The hardware of weighing system is reasonable in structure,and the software is advanced in design,which provides a good example for application of computer in the electronic balancer.
