Manufacture and Application of a New Kind of Track Static Parameter Measurer

从智能化仪器仪表的角度描述了一种新型的轨道静态几何参数检测仪的设计过程,给出了轨距、高低、轨向、水平、里程参数测量的数学模型以及硬件电路的设计思路,并在控制系统误差处理中采用实时自校准方法修正由于各种漂移、增益不稳定等因素引起的系统误差,提高仪器的测量精度;最后文中给出了应用该仪器的实际检测案例,结果表明该设计完全可以达到精度的要求,具有很好地推广应用前景和重大的经济效益。

Based on the view of intelligent instrument and apparatus, the designing process of a new kind of track static parameter meas urer is presented, and the mathematics model of gauge, height, orientation, level and mileage are put forward, the design thought of hard ware circuit is introduced. The real-time self-calibration is adopted to modify various kinds of system tolerance caused by drift, gain and other unsteady effects, resulting in a good improvement on measurement precision of apparatus. A practical case is also presented, the result indicated that its design can achieve the precision demand completely, and it has a wide application foreground and good economic profit.
