Embodiment Construction

[0030] The present invention will be described in detail below in combination with specific embodiments.

[0031] A method of measuring the illuminance of a locomotive vehicle using the 9-point method of the present invention is specifically implemented according to the following steps:

[0032] Step 1. According to the installation height of the current vehicle lamps and the distance between the lamps and the measuring probe, calculate the theoretical center position H0 where the measuring probe needs to move, specifically:

[0033] Step 1.1. Set the distance between the lamp and the measuring probe as 60m, and set the installation height of the current vehicle lamp as H;

[0034] Step 1.2. According to the requirements of TB / T2325.1-2013, align the brightest point of the light spot of the headlight with the focus position of the track center 300m ahead, and calculate the theoretical center position H0 where the measuring probe needs to move. The calculation formula is as fol...

Abstract

The invention discloses a method for measuring complete vehicle illuminance of a locomotive through a nine-point method. Firstly the distance of a probe is measured according to the installing heightof the current complete vehicle lamps and the lamp distance, and the theoretical center position H0 required to be moved by the measurement probe is calculated; then the measurement probe moves to allthe detection points of the nine-point method with H0 acting as the center position and performs measurement recording; and finally whether the distribution of the maximum current illuminance position is the position of H0 is judged, whether the standard illumination requirements are met is directly judged according to the requirements if the judgment result is yes, and adjustment of the lamp angle is guided according to the distribution position of the current maximum point if the maximum point is not the position of H0 and the maximum point of illuminance is adjusted to the position of H0.The problems of tedious measurement method of complete vehicle illuminance and waste of manpower and material resources in the prior art can be solved.

Description

technical field [0001] The invention belongs to the technical field of illumination measurement of locomotives, and in particular relates to a method for measuring the illumination of an entire locomotive using a 9-point method. Background technique [0002] The design basis of the existing locomotive headlights is TB / T2325.1-2013 "Locomotive, EMU Headlights, Auxiliary Lights and Sign Lights Part 1: Headlights", which was issued in 2013. This standard also stipulates the required value of illuminance in the locomotive vehicle test and the test method of outdoor illuminance. [0003] The current measurement of vehicle illuminance is based on the measurement distance and measurement height required in TB / T2325.1-2013, using the method of manual measurement with an illuminance meter. This method needs to align the brightest spot of the headlight spot with the center of the track 300m ahead, and use manual methods to test the illuminance every 100m. direction. This method nee...
