本论文选用Apple-Ⅱ作主机,开发了一套外设接口扩展箱和相应的应用软件,用于实现在钢厂中对六台单轧机的热轧钢板长度在线检测和现场显示,同时对钢板的长度按照合格、超长、超短进行分类统计,打印生产报表。此外还提供随时修改钢板长度(标尺)设定值和随机查询各台轧机产质量状况的功能。在接口扩展箱中,采用了包括光电耦合在内的若干抗干扰措施,保证系统能在钢厂恶劣环境中正常运行。本系统已在工厂轧机上试用成功。
This paper selects Apple-Ⅱ as the host, developed a set of peripheral interface expansion box and the corresponding application software, used in the steel mill to achieve the six single-rolling mill hot-rolled steel length online detection and on-site display, while the steel According to the length of the qualified, long, short classification statistics, print production reports. In addition, it also provides the function of changing the set length of the steel plate (ruler) and randomly querying the quality of each rolling mill at any time. In the interface expansion box, using a number of anti-interference measures, including optoelectronic coupling, to ensure that the system can work in harsh steel mills. The system has been successfully tested on the mill.
