[Abstract]Based on the research and implementation of the problems in the intelligent master control system for blast furnace main hoisting car travel detection， a method and means for rapid correction after the code value error occurs in the blast furnace main hoisting car travel control encoder is proposed. It solves the problem of quickly correcting the encoder when the main coil material car travel control encoder is caused by the loss of control parameters， abnormal power failure， loose mechanical receiver， main coil motor wire rope replacement， encoder replacement， etc.， when the material car travel detection error occurs. The implementation of this topic has realized the one-key correction of the encoder， reduced troubleshooting time， improved maintenance efficiency， and provided a strong guarantee for the continuous production of the blast furnace， and at the same time reduced the safety risks for the operators.

1 概述

主卷揚料车上料系统是目前国内大多炼铁高炉采取的上料方式。作为料车行程检测的重要组成部分，智能主令控制器因其运行可靠、响应速度快、精度高等优点代替老式凸轮主令控制器广泛应用于高炉主卷扬料车行程检测系统中。

该系统虽然优势明显，但是存在致命的缺点，即编码器由于异常断电、机械接手松动、主卷电机钢丝绳更换、编码器更换等都会引起车行程检测错误，此时需要电气维护人员拆开编码器与电机轴连接端盖，通过手动旋转编码器进行校正，处理时间较长，对高炉的连续生产造成了严重的影响，并且存在很大的安全风险。

本文以酒钢2#高炉主卷扬料车行程控制系统为例，介绍针对上述存在的问题的具体解决方案，从控制程序着手，优化编码器码值计算算法，最终实现编码器的“一键校正”。……
