介绍MCS—51系列单片机在球墨铸铁熔炼配料监控系统中的具体应用,包括系统硬件组成和软件结构,它能完成:(1)自动秤量和打印每次加入的三种原料的重量;(2)自动打印这三种原料的每日累积值;(3)自动记录和打印每两次加料的间隔时间;讨论了在动态情况下,处理所采集的拉力信号的方法。系统所采用的各种抗干扰措施,经实践证明是有效的和必要的。该系统保证了球黑铸铁熔炼的质量,提高了产品的合格率,并为产品性能的分析提供了依据。
This paper introduces the application of MCS-51 MCU in ductile iron smelting ingredients monitoring system, including system hardware composition and software structure. It can accomplish the following tasks: (1) automatically weigh and print the weight of three raw materials added each time; (2) Automatically print the daily accumulated values of the three raw materials; (3) automatically record and print the interval between two feeding times; and discuss the method of processing the collected tensile force signal under dynamic conditions. Various anti-jamming measures adopted by the system have proved to be effective and necessary in practice. The system ensures the quality of the ball black cast iron smelting, improve the pass rate of the product, and provide a basis for the analysis of product performance.
