钢水温度、含碳量、含氧量是控制冶炼生产,保证钢的质量的关键指标,因此这方面的测量仪表对于冶炼生产非常重要。目前国内各钢厂主要以长图或圆图记录仪作为这三个参数的测量仪表,精度低,并且测量时指针随信号不断晃动,常常出现很大的人工读数误差。因此,迫切需要研制一种高精度的智能仪表,自动选择最佳测量时机,消除人为误差和信号中干扰成分的影响,稳定地显示和保持测量结果。 微处理机的广泛应用,为研制这样一种 Molten steel temperature, carbon content, oxygen content is to control the production of smelting, the key indicators to ensure the quality of steel, so measuring instruments in this regard is very important for smelting production. At present, the domestic steel mills mainly use the long graph or the circular graph recorder as the measuring instrument of these three parameters, which has low precision and the pointer constantly fluctuates with the signal when measuring, and often has a great manual reading error. Therefore, there is an urgent need to develop a high-precision smart meter that automatically selects the best measurement timing, eliminates human error and the influence of interfering components in the signal, and displays and maintains the measurement results stably. Microprocessor widely used to develop such a
