Embodiment 1

[0023] Example 1: see Figure 1 to 3 As shown, an elevator gauge deviation analysis method based on displacement sensor ranging, adopting displacement sensor for elevator gauge measurement, includes the following steps:

[0024] (1) Installation of measuring equipment: install two displacement sensors on the fixed structures on the left and right sides of the top of the elevator car respectively. The two displacement sensors are electrically connected to the host computer with built-in A / D chip and single-chip microcomputer. And a digital filter, the analog signal measured by the displacement sensor reaches the single-chip microcomputer through the A / D chip, and the output terminal of the single-chip microcomputer is connected to the digital filter;

[0025] (2) Establish the analysis function of the elevator gauge deviation: the elevator gauge error includes the error of the ranging tool itself , Fixed error between probes And the error caused by the car tilt , Then the elevato...

Embodiment 2

[0035] Embodiment 2: Measuring the gauge deviation of an elevator, the specific implementation method is as follows:

[0036] ① Error e1: Using two miniature linear displacement sensors with a measuring range of 25mm, with a linear accuracy of 0.2%, the resulting measurement error of the instrument is e1=50×0.2%=0.1mm.

[0037] ②Error e2: Use a tape measure to measure the fixed distance between the two probes installed, and the measurement accuracy can reach e2=0.4mm (subjective factors of the surveyor are greatly affected, but it can be controlled within 0.5mm). If you measure multiple times and take the average, you can significantly reduce this error.

[0038] ③Error e3: When the gap between the guide shoes and the track on both sides reaches 4mm, the measurement error caused by the tilt of the car is about e3=4×1%=0.04mm.

[0039] In summary, the gauge deviation of the elevator designed by the present invention is e=e1+e2+e3=0.54mm.

Description

Technical field [0001] The invention relates to an analysis method, in particular to an elevator gauge deviation analysis method based on displacement sensor distance measurement. Background technique [0002] The elevator car runs up and down along the guide rails. The quality of the installation of the elevator guide rails, especially the gauge and deviation, directly affects the smoothness of elevator operation and the comfort of passengers. At present, the common measurement methods specified in "Content Requirements and Methods of Elevator Supervision and Inspection" are: control the elevator to run up and down, and measure the gauge with a steel tape at the rail support near the jitter position. This method of measuring the elevator gauge and deviation with a steel tape on the top of the elevator car has the disadvantages of difficult operation, low efficiency, poor accuracy, and obvious influence of subjective factors. In order to overcome the shortcomings of very large d...
