Hereinafter, the structure and operation of the present invention will be described in more detail with reference to the accompanying drawings. In describing the present invention, terms and words used in the present specification and claims are to be construed in accordance with the principles of the present invention, on the basis that the inventor can properly define the concept of a term in order to best explain his invention It should be construed as meaning and concept consistent with the technical idea of.

The fault monitoring system using the railroad car illumination lamp of the present invention is a system for deriving a wheel portion deficiency of a railway car through an illumination lamp 1 of a railway car as shown in FIG. 1, (2) configured to detect sound or vibration from a railway vehicle wheel, A control unit (3) which is constituted by an illumination lamp of a railway vehicle and receives a sensing value from the sensing sensor (2) and applies an output signal when the sensing value exceeds a set value; And an alarm unit 4, which is formed in the illumination lamp 1 of the railway vehicle and includes an LED warning lamp that is turned on by receiving the output signal.

That is, according to the present invention, when an abnormality is detected by detecting sound or vibration of an abnormality of a bearing or the like in a railway vehicle, the LED warning light 41 formed in the illumination lamp 1 of the railway vehicle is automatically turned on, Economic, and accuracy. 1, the illumination lamp 1 is installed for illuminating a room of a railway car, and the present invention is applied to a known structure of a conventional illumination lamp 1, in which the detection sensor 2, the control unit 3, And the warning part 4 is further included.

Therefore, the known configuration of the conventional illumination lamp 1 is omitted and the configuration of the detection sensor 2, the control unit 3 and the warning unit 4 is not limited to the known configuration of the conventional illumination lamp 1 will be. For example, FIG. 1 shows an example in which the warning unit 4 is configured adjacent to a known configuration of an existing illumination lamp 1. In FIG.

The detection unit 2 and the control unit 3 may be included in a known configuration of the conventional illumination lamp 1 but the warning unit 4 may be configured in a known configuration of the existing illumination lamp 1, It is appropriate that the irradiation by the LED warning lamp 41 of the warning unit 4 is exposed and the irradiation is detected by the manager or the like.

This configuration eliminates the need to mount a separate structure for defects such as the wheel portion of the railway vehicle, and it is possible to monitor the defects such as the wheel portion of the railway car by simply installing the illumination light 1 of the railway vehicle on the railway vehicle It is advantageous in terms of the economy of the facility.

Here, "railway vehicle" is a broad concept including subway, electric train, monorail train, and the like.

The sensing sensor 2 is a sensor for sensing sound or vibration, and various known technologies exist, and a description thereof will be omitted.

The control unit 3 receives the sensing value from the sensing sensor 2 and transmits an output signal to the warning unit 4 when the sensed value exceeds the set value. For example, a constant acoustic value or a vibration value may be set in a predetermined period.

That is, when the sensing value from the sensing sensor 2 exceeds a predetermined acoustic value or vibration value over a predetermined period, the control unit 3 transmits an output signal to the warning unit 4, The LED warning lamp 41 is turned on.

The controller 3 includes an A / D converter for converting an analog signal of the sensing sensor 2 into a digital signal, which is not shown in the drawing, and a digital-to- A controller for determining an abnormality of the bearing based on the amplitude and the frequency component of the received digital signal using a diagnostic program and generating an output signal when an abnormality occurs, And a transmitter for wirelessly transmitting the output signal to the warning unit 4 according to a control signal of the controller.

The warning unit 4 includes an LED warning lamp 41 that is turned on by receiving the output signal. The manager determines whether or not to check the bearing of the corresponding wheel according to whether the LED warning lamp 41 is turned on will be.

As shown in FIG. 2, the illumination unit 1 of the railway vehicle includes a communication unit 6 to transmit a lighting signal when the LED warning lamp 41 of the warning unit 4 is lit, And an administrator terminal 5 for receiving an administrator terminal 5.

That is, instead of determining whether or not the LED warning lamp 41 is lit only by the naked eye of the manager, the communication unit 6 automatically transmits a lighting signal when the LED warning lamp 41 is lit, The manager terminal 5 located within the short-distance communication distance automatically receives the lighting signal, and the manager can identify whether the corresponding LED warning lamp 41 is lit or not. Here, since various known technologies can be applied to the short-range communication between the communication unit 6 and the administrator terminal 5, the description thereof will be omitted.

On the other hand, another embodiment is shown in Fig. 3 and Fig.

In the present embodiment, the LED warning light 41 is irradiated with visible light having a wavelength of a specific region, for example, blue light may be irradiated at a wavelength of 500 to 450 nm with a wavelength of a specific region.

The manager terminal 5 is provided with a sensing unit 51 for sensing only visible light having a wavelength of a specific region illuminated by the LED warning lamp 41, The LED 51 is automatically turned on when the LED warning lamp 41 is turned on.

The reason for irradiating and detecting only the visible light having the wavelength of the specific region is to exclude the light irradiated from other lights other than the LED warning lamp 41 such as the illumination lamp 1 of the railway vehicle. Since the sensing unit 51 can be realized by a known technology such as a photo-sensing sensor, a description thereof will be omitted.

The manager terminal 5 is further provided with a display unit 52 for displaying the sensing signal of the sensing unit 51. The manager can easily light the LED warning light 41 through the display contents of the display unit 52 .

The warning unit 4 includes an RF chip 43 having unique identification information embedded therein as shown in FIG. 4 and an RF reader 53 for reading the RF chip 43, Is further included.

The RF chip 43 having the unique identification information of the warning unit 4 is configured in the warning unit 4 as the information about the position of the warning unit 4, It corresponds to the information about a few wheels of a railway car.

When the LED warning lamp 41 is turned on in the warning part 4 and the manager goes to the adjacent part of the warning part 4 with the manager terminal 5, The lighting of the LED warning lamp 41 is detected in the control unit 4 and at the same time the RF reader 53 reads the RF chip 43 of the warning unit 4. [

Thus, the information read by the RF reader 53 is displayed on the display unit 52 so that the manager can accurately recognize the number of the wheels of the railroad car. Naturally, the administrator terminal 5 should include a database unit for notifying the administrator terminal 5 that the information transmitted from each warning unit 4 is data.

As shown in FIG. 5, the warning unit 4 includes an LED warning lamp 51 and at least one irradiation hole 421 through which the LED warning light 51 is enclosed, The housing 42 to which the absorbent coating layer 422 is applied may be included.

5 shows an example in which the LED warning lamp 41 is configured inside the housing 42 and the housing 42 adjacent to the existing known configuration of the railway car illumination lamp 1, but the position thereof is not particularly limited.

The reason for constructing the housing 42 for controlling the direct exposure of the LED warning lamp 51 by enclosing the LED warning light 51 in the outside is that when the LED warning lamp 51 is lit, To detect the facts easily and to control anxiety about the abnormality of the railway vehicle.

That is, the housing 42 is configured to surround the LED warning light 51 so as to control the direct exposure of the LED warning light 51, while detecting the lighting of the LED warning light 51 by the manager terminal 5 The irradiation hole 421 is formed so that only a minimum visible ray is radiated to the outside of the housing 42 so that visual detection by the passenger is not easy.

The visible light absorbing coating layer 422 is applied to the inner and outer surfaces of the housing 42 so that the light emitted from the LED warning lamp 51 does not generate afterglow on the housing 42, So that only investigation can be done. That is, visibility by the passenger is almost impossible to be detected, and only the detection by the manager terminal 5 is made possible, thereby blocking the recognition of the passenger.

In addition, the present invention provides an example of the composition of the visible light absorbing coating layer 422.

The visible light absorbing coating layer 422 of the present embodiment contains 10 to 20 parts by weight of cellulose acetate, 1 to 5 parts by weight of aluminum hydroxide, 1 to 5 parts by weight of iron oxide iron and 1 to 3 parts by weight of zinc stearate with respect to 100 parts by weight of carbon black The visible light shielding powder is dispersed in a solvent and is formed by thermosetting.

The carbon black is added as a visible light blocking material because the visible light absorption coefficient is significantly higher than the infrared absorption coefficient.

However, carbon black has a problem causing generation of haze, and there is a problem that the generation of condensation on the surface may occur due to the occurrence of such haze. Such condensation can act as a point for diffusing the irradiated and reflected light, so that the condensation generated in the housing 42 due to a temperature difference within the railway car must be controlled to the maximum. Therefore, in the present invention, cellulose acetate is added together with carbon black to hydrophilize the surface of the coating layer to control the generation of condensation.

The aluminum hydroxide absorbs heat generated in the heat curing process and is decomposed into aluminum trioxide and water. That is, it is possible to control the temperature crack by reducing the hardening heat.

In addition, when water is used as a solvent, water evaporates in the course of thermosetting and cracks are generated by the evaporation of the water. In addition to absorbing heat by adding aluminum hydroxide, water is decomposed into aluminum trioxide and water, Function.

In addition, it is necessary to control the autogenous shrinkage by preventing the surplus water from being rapidly evaporated and dried in the thermosetting process, and it is necessary to control the crack due to plastic shrinkage due to drying of the surface of the coating layer by such evaporation. Accordingly, in the present invention, sulfur oxide is further added, and sulfur iron oxide is used to control the autogenous shrinkage of the paste by delaying the reaction rate to induce the continuous reaction.

That is, the addition of the sulfur iron oxide added for the purpose of delaying the reaction can significantly suppress the shrinkage of the paste. This is because sulfur iron oxide generates acicular crystals in the heat curing process and induces the paste to a dense structure by the growth pressure of the acicular crystals. That is, as many fine needle crystals are developed, the expansion pressure can be obtained, thereby reducing the effect of shrinkage, thereby controlling microcracks due to self-shrinkage. Such microcracks may also act as a point of occurrence of condensation, and therefore control of microcracks is required as much as possible.

The zinc stearate is prepared by synthesizing zinc oxide and stearic acid at a high temperature. The zinc stearate is mixed with the hydrophilic solution to form an emulsion, which functions as a dispersant and performs a release function.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
