Description

Electric wheel digital wheel gauge {Digital whill gauge of electric rail car}

The present invention relates to an electric vehicle digital wheel gauge, and more specifically, a digital wheel gauge is configured as a digital wheel gauge so that the gauge can be easily found and measured at two points at a time by measuring the exact center of the axle, which is a measuring point, for accurate wheel management. The present invention relates to an electric vehicle digital wheel gauge that enables accurate speed control and precise stop operation of a train by providing accurate information.

In general, electric vehicles are based on automatic operation by a computer system (hereinafter referred to as ATO). Therefore, the wheel values of the wheels must be precisely managed for automatic driving and safe driving, so that the wheel values are managed by the same axis, the same truck, the same vehicle, and the same unit. The wheel wheel value of electric train is the most basic value for the automatic operation of the train, and by inputting the correct wheel value to the train control device (hereinafter referred to as TCMS) and the train automatic control device (hereinafter referred to as ATC), the train speed and Precise stop is controlled.

Hurenji height and thickness of electric car wheels prevent derailment of seriously handicapped trains, so errors in Hurenji measurement can affect safety driving and wheel diameter of 4mm to restore 1mm Hurenji circle during wheel processing. This was an important factor in reducing the wheel life. The above-mentioned corrections are made in the case of the wheel hard car and the Hurenji abnormal abrasion, the other scratches and grooving.

Wheel wheel value of electric vehicle is used to calculate train speed and exact stop point during automatic driving, and input method is slightly different for each line. The wheel value of the wheel of the electric vehicle is used to stop the train speed and the exact position, and when calculating the speed of the ATO, calculating the actual ATC speed and manifesting the ADU, generating the distance pulse every 25m of the automatic broadcasting device, generating the distance pulse of the passenger guidance device. It is used to detect wheel slip slides at train speeds and train speeds, for anti-skid operation, and to calculate distance information (TDB) in the ATO.

The C-type gauge is composed of the height-shaped bar height measuring bar 530, but the C-type gauge is made of stainless steel with a thickness of 1 mm, and the measurement scale is 2 mm units. An error occurred and the scale Since the upper part is 2mm, it has a big influence on the occurrence of the error, and the measurement time is consumed by measuring and using the average of three points of one wheel to reduce the error range. There was a lot of problems, such as excessive input, consumption of a large amount of measurement costs, and the possibility of safety accidents due to the narrow measurement site.
