摘　　要：A system for measuring the quality parameters of elevator guide rails is developed. The quality parameters the system can measure include straightness, flatness, squareness, width and height of the rail. The system consists of six parts：main guideway, auxiliary guideway, reference rail, saddle, control casing and measured rail. The guide rail to be measured is mounted on a bed. The straightness errors of surfaces are checked by five linear displacement sensors mounted on the saddle. The deviation of readings from the sensor, which is in contact with top guiding surface, gives the straightness error of the surface and height of the rail. The other four sensors are used to measure side guiding surfaces respectively and give other parameters including flatness on the surfaces, squareness, width and height of the rail. A novel calibration method is also developed to calibrate the straightness motion error of the system in horizontal and vertical directions. The deflection deformation of the measured rail is fitted by using a fourth-order polynomial. Experimental results show that the uncertainty of the system on the side surfaces after compensating the straightness motion error is less than 0. 01 mm, and the uncertainty of the system on the top surface after compensating the straightness motion error and the deflection deformation of the rail is less than 0. 03 mm.为测量电梯指南栏杆的优秀参数的一个系统被开发。系统能测量的优秀参数包括栏杆的笔直，平坦，方形，宽度和高度。系统由六部分组成：主要指南方法，辅助指南方法，参考栏杆，僵绳，控制套和测量栏杆。要测量的指南栏杆在一张床上被装。表面的笔直错误被传感器在僵绳上装了的五线性排水量检查。从传感器的读物的偏差，它在与最高的指导联系表面，给栏杆的表面和高度的笔直错误。另外的四个传感器被用来测量分别地指导表面的方面并且在栏杆的表面，方形，宽度和高度上包括平坦给另外的参数。一个新奇刻度方法也被开发在水平、垂直的方向校准系统的笔直运动错误。测量栏杆的偏转变丑被使用 fourth-orderpolynomial 适合。在补偿笔直运动错误是不到 0 以后，试验性的结果证明方面上的系统的不确定性出现。在补偿笔直运动错误和栏杆的偏转变丑是不到 0.03 公里以后，顶上的系统的 01 公里，和不确定性出现。
