Description

A kind of method that locomotive whole-vehicle illuminance is measured using 9 methods
Technical field
The invention belongs to locomotive whole-vehicle illuminance measurement technical field, and in particular to one kind is whole using 9 methods measurement locomotives The method of car illuminance.
Background technology
The design considerations of existing locomotive headlamp is TB/T2325.1-2013《Locomotive, headlamp of motor train unit, auxiliary illuminator and Identification light part 1：Headlamp》, the standard in 2013 promulgate issue.The standard is equally defined in locomotive whole-vehicle experiment The test method of illuminance required value and outdoor illuminance.
The measurement distance and measurement height required in the current beasurement base TB/T2325.1-2013 for vehicle illuminance Using the method manually measured with illumination photometer.This method needs the hot spot of headlamp most bright spot being aligned at the 300m of front Orbit centre, an illuminance is tested every 100m using manual method, illumination photometer probe hangs down at 0.5m above rail level Directly in the direction of headlamp incident light.This method at least needs 4 points between measurement 200m-500m of illuminance value, at most needs 5 points of illuminance value between measurement 200m-600m.Measuring point is excessive in actually measuring, measuring distance farther out, and waste of manpower and Material resources.In addition, this method is only limited to carry out the vehicle illuminance detection of type approval test, the party is used for the light fixture of normal entrucking Method measurement is quite cumbersome.

It is an object of the invention to provide a kind of method that locomotive whole-vehicle illuminance is measured using 9 methods, solves existing skill The measuring method of vehicle illuminance present in art is cumbersome, waste of manpower and the problem of material resources.
The technical solution adopted in the present invention is a kind of method that locomotive whole-vehicle illuminance is measured using 9 methods, specifically to press Implement according to following steps：
Step 1, the distance popped one's head according to the setting height(from bottom) of current vehicle light fixture and light fixture range measurement, calculate measuring probe Need the theoretical center position H0 moved；
Step 2, measuring probe are respectively moved to each test point of 9 methods of the position centered on H0 and measure record；
Step 3, judge the distribution of current light degree maximum position whether in H0 positions.
The features of the present invention also resides in,
Step 1 is specially：
Step 1.1, the distance of light fixture range measurement probe is set as 60m, if currently the setting height(from bottom) of vehicle light fixture is H；
Step 1.2, according to TB/T2325.1-2013 requirement the hot spot of headlamp most bright spot is aligned at the 300m of front The focal position of orbit centre, calculates the theoretical center position H0 that measuring probe needs to move, and calculation formula is as follows：
H0=240*H/300 (1).
Step 2 is specially：
Step 2.1, the motor anglec of rotation according to corresponding to umber of pulse obtains individual pulse, in conjunction with " the speed of reductor Than ", displacement stroke corresponding to corresponding rotating mechanism is obtained, so as to obtain displacement corresponding to individual pulse or rotating distance, finally H4, H5 and H0 that control measuring probe is automatically moved into the left and right each 300mm opening positions of theoretical position H0, H0 are upper and lower each H1, H2, H3, H6, H7, H8 of 300mm opening positions, altogether 9 points measurement position；
Step 2.2, the brightness value for measuring H1~H9 each position are simultaneously recorded.
Step 3 is specially：
Whether the distribution of current light degree maximum position is judged in H0 positions, if directly determining whether to meet as requested Normal luminance requirement；, will if maximum point in H0 positions, the adjustment of light fixture angle is not instructed according to the distributing position of current maximum point Illumination maximum point is adjusted at H0.
Whether the distribution of current light degree maximum position is judged in H0 positions, it is specific as follows：
H0 meets the brightness value more than remaining measurement position simultaneously when, the focal position of current headlamp is correct, is hitting exactly The heart focuses on, and without adjustment angle, if now H0 points test value is unqualified, illustrates that headlamp illumination itself is inadequate；
H1 meets the brightness value more than remaining measurement position simultaneously when, headlamp focusing angle is located at upper left, it is necessary to will be poly- Burnt position is turned right lower adjustment；
H2 meets the brightness value more than remaining measurement position simultaneously when, headlamp focal position is positioned at just upper, it is necessary to will be poly- Burnt position adjusts toward lower section；
H3 meets the brightness value more than remaining measurement position simultaneously when, headlamp focal position is located at upper right, it is necessary to will be poly- Burnt position adjusts toward lower left；
H4 meets the brightness value more than remaining measurement position simultaneously when, headlamp focal position is located at left side, it is necessary to will be poly- Burnt position is turned right adjustment；
H5 meets the brightness value more than remaining measurement position simultaneously when, headlamp focal position is located at right side, it is necessary to will be poly- Burnt position adjusts toward left side；
H6 meets the brightness value more than remaining measurement position simultaneously when, headlamp focal position is located at lower-left, it is necessary to will be poly- Burnt position is turned right upper adjustment；
H7 meets the brightness value more than remaining measurement position simultaneously when, headlamp focal position is positioned at just lower, it is necessary to will be poly- Burnt position adjusts toward top；
H8 meets the brightness value more than remaining measurement position simultaneously when, headlamp focal position is located at bottom right, it is necessary to will be poly- Burnt position adjusts toward upper left side.
The invention has the advantages that the automatic measurement of locomotive whole-vehicle illuminance, pin can be quickly realized using this method The adjustment that the headlamp of standard requirement is unsatisfactory for illuminance provides guidance, and current vehicle illumination is enormously simplify using this method Degree uses the problem of cumbersome measuring method in manpower detection, waste of manpower and material resources, while can realize that institute of locomotive depot is organic The timely detection and adjustment of car vehicle illuminance, it is ensured that traffic safety.
