Description

In this paper, we propose a new method for image analysis for railway vehicles.

The present invention relates to an oiler, and more particularly, to an oiler using an image analysis method that enables an accurate amount of grease to be discharged through an image analysis, through which an accurate amount of grease is discharged to a rail through image analysis.

Generally, a trolley is used to automatically lubricate a lubricant such as a high-viscosity grease in order to sense trains entering on a rail in a curved section and to prevent wheels and rails of a rail and a train from being worn and noise generated.

That is, in the curved section of the rail, a load acts on the wheel in a direction perpendicular to the direction in which the train is rotated by the centrifugal force, and a severe friction is generated between the wheel and the rail.

Prior art relating to such trowel is disclosed in Korean Patent Application No. 10-2013-0124815 (Filing Date: 2013.10.18), No. 10-2001-0030432 (Filing Date: 2001.05.31), No. 10-2006-0025900 Filed March 22, 2006).

However, such conventional trowelers are difficult to precisely apply the grease because it is difficult to precisely grasp the amount of grease applied to the rail by concentrating only on application of a fixed amount of grease on the basis of sensing the entrance of a train through a sensor.

Further, there is a problem that it is difficult to control the amount of grease discharged in each section of each rail.

It is an object of the present invention to provide a tappet using image analysis in which an accurate amount of grease can be discharged onto a rail by checking the amount of grease discharged onto a rail.

A tandem machine using image analysis according to the present invention is a tandem machine for discharging grease to a side of a rail, the tandem machine being installed adjacent to the rail and photographing a side of the rail, comprising a camera, And a bracket for fixing the rotation unit; An image analyzer for analyzing an image transmitted from the camera unit and analyzing the amount of grease discharged to the rail; A grease supply portion provided adjacent to the rail to supply grease; A distributor installed in a supply line of the grease supply unit; A plurality of discharge portions provided on side surfaces of the rails; A plurality of distribution lines connecting the distributor and the plurality of discharge units; A regulating valve installed on the distributing line for regulating the amount of grease moved to the discharging portion; And a control unit for controlling the grease supply unit and the control valve according to a signal transmitted through the image analysis unit, wherein the image analysis unit is operated through a sensor installed in order to confirm the entry of the train, , Analyzes the still image signal according to the photographed frame unit continuously through the difference in lightness value, analyzes the amount of grease discharged to the rail through each of the discharging units, and transmits the analyzed amount of grease to the control unit together with the image do.

The image analyzer using the image analysis according to the present invention has an advantage that it can provide an image analyzer using an image analysis that enables an accurate amount of grease to be discharged to a rail through an image analysis of a camera unit and a control valve provided in a supply line.

1 is a conceptual diagram illustrating a metering device using image analysis according to a preferred embodiment of the present invention;
2 is a conceptual diagram showing a distributor and a control valve according to a preferred embodiment of the present invention;
3 is a cross-sectional view illustrating that a distributor and a control valve are mounted on a rail according to a preferred embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a conceptual diagram showing a metrology apparatus using image analysis according to a preferred embodiment of the present invention.

1, the calculator using image analysis according to the present invention includes a camera unit 100, an image analysis unit 200, a grease supply unit 300, a distributor 400, a dispensing unit 500, and a distribution line 550 A control valve 600, and a control unit 700. As shown in FIG.

First, the camera unit 100 and the image analysis unit 200 will be described. The camera unit 100 is installed adjacent to the rail, captures an image for monitoring whether the amount of grease discharged onto the rail is discharged in a predetermined amount And transmits it to the image analysis unit 200.

The image analysis unit 200 analyzes the image transmitted from the camera unit 100 and transmits the analyzed image to the control unit 700, which will be described later. This image analysis technique continuously analyzes the discharge amount of the grease through the differences in contrast values of the still image signal by the photographed frame unit, and analyzes the amount of grease discharged to the rail through each discharge part 500. The analysis data is transmitted to the control unit 700 together with the image.

It is preferable that the operation of the image analysis unit 200 is previously set so as to confirm entry of the train by using a separate sensor or to determine whether the operation is performed through the passage time of the inputted train.

In order to accurately photograph the amount of grease discharged onto the side surface of the rail, the camera unit preferably includes a camera, a rotation unit for rotating the camera left and right, a rotation unit for rotating the camera left and right, and a bracket for fixing the rotation unit.

The grease supply unit 300 is provided adjacent to the rail to supply grease. Specifically, the grease supply unit 300 includes a grease reservoir 310 in which grease is loaded, and a grease reservoir 310, (320).

Next, when we look at the discharge process of Greece,

3 is a cross-sectional view showing that a distributor and a control valve according to a preferred embodiment of the present invention are mounted on a rail.

As shown in FIG. 3, a plurality of discharge units 500 are provided adjacent to the side surface of the rail 1, and the grease discharged through the distributor 400 is discharged.

2 is a conceptual diagram showing a distributor and a control valve according to a preferred embodiment of the present invention.

As shown in FIG. 2, a plurality of discharge units 500 are installed on the sides of the rails to discharge grease. The distributor 400 and the distribution line 50 are connected to each other through a supply line 330 When the grease is supplied, the distributor 400 distributes the grease to each discharge portion 500 through the plurality of distribution lines 550 and supplies the grease.

In this distribution line 550, a regulating valve 600 for regulating the amount of grease transferred to the discharging unit 500 is installed, and the regulating valve 600 can regulate the amount of grease transferred through the regulating unit 600 .

The amount of the grease discharged to the side of the rail can be adjusted through the control part for controlling the grease supply part and the control valve according to the signal transmitted through the image analysis part.

However, the operation of the image analysis unit may be such that the controller supplies grease to the discharge unit through the supply pump of the grease supply unit to discharge the grease to the side of the rail through a sensor capable of detecting the movement of the train, The side of the auxiliary rail is photographed and the amount of discharged grease is analyzed by the image analysis unit. Through this process, if the amount of grease is insufficient or insufficient, the control unit controls the amount of grease discharged by controlling the regulating valve so that a desired amount of grease can be discharged to the side of the rail.

As described above, according to the present invention, it is a main technical idea to provide a metrology tool using image analysis, and since the embodiments described above are only one example with reference to the drawings, the true scope of the present invention is not limited to Should be determined.
