Description

Wheel Scratch Automatic Inspection Device

The present invention relates to an apparatus for accurately inspecting the wheel scratch condition, which is a phenomenon in which the wheels are rubbed with the road surface during braking of an electric vehicle such as a subway or a train, and wears in detail. The train number of the train and the wheel scratch information of the train can be automatically transferred to the main computer in the Depot for inspection repair (hereinafter referred to as the inspection base) for inspection and repair. If the wheel scratch information is suspected, the inspection station can inspect the wheels of the train more accurately, thereby precisely analyzing the inspection of the wheel scratches and storing and outputting the data. Rapid reshaping can improve the precision of wheel inspection and the efficiency of work computerization. It relates to a wheel scratch automatic inspection device.

At present, the wheel scratches generated as a result of friction between the wheels and the road surface when operating in electric vehicles such as subways and trains, especially during braking, are not only deteriorating ride comfort, but also becoming a major factor in generating loud noise. Therefore, the scratches of such wheels must be inspected quickly so that the inspection station can replace or trim the wheels of the train. An example of an apparatus for inspecting the scratch state of such wheels is disclosed in Korean Patent Application Publication No. 94-11274. There is.

The wheel scratch inspection apparatus inputs a combination data of the vehicle to be inspected (for example, train number, train passing time, train speed, data of wheel scratch inspection apparatus operation and measuring instrument operation) on a keyboard, The vibration sensor was installed to check the vibration state of the wheel once and to collect information on the imaging of the wheel.

However, the conventional wheel scratch inspection apparatus as described above has a hassle to manually input the number, train passing time, train speed, etc. of the train operated by the attendant at the time of detection, and also when the vehicle is inspected at the inspection station. There is a problem in that it is impossible to quickly check the wheel scratches because the data is output only when the number is manually input.

In addition, in order to accurately detect the wheels at the inspection station, trains must be operated at a specified speed (for example, 25 km / h or more) to accurately detect wheel scratches by a vibration sensor, and a conventional wheel scratch inspection device can confirm this. Since the train speed limiter is not provided, there is a problem that a delay of inspection occurs due to the train repeatedly running several times.

In addition, since the conventional wheel scratch inspection device has no linkage with the wheel cutting device, it takes a long time from grasping the wheel scratch to reshaping (cutting) the wheel, thus making it impossible to quickly repair the wheel.

The present invention is to solve the problems of the prior art, instead of manually inputting the train number to inspect the wheel scratches of the train on the ground side, by automatically inspecting the train number and the scratch state information of the wheels to determine the It is possible to quickly analyze and store the wheel information of the train by sending it to the main computer, and it is equipped with a train speed limiting device to know whether the train is operating at a specified speed for accurate inspection of the wheel at the inspection station. It is possible to eliminate the delay of inspection by several repetitive operation of trains such as the train, and by linking the wheel information analyzed by the main computer with the wheel cutting device, it is possible to quickly cut the scratched wheels and to quickly introduce the train to the sales line. The purpose of the present invention is to provide an automatic wheel scratch inspection device.

An embodiment of the present invention configured as described above will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, the main computer 21 of the data analysis processing unit 20 examines the data transmitted from the ground inspection unit 10 and analyzes the transmitted data. The number is notified to the controller 34 of the inspection base side inspection unit 30 to instruct the controller 34 of the inspection base side inspection unit 30 to recheck the reported train precisely.

The controller 34 of the inspection vehicle base inspection unit 30, which has received the name and wheel number of the train from the main computer 21, causes the train speed limiting means 35 to set the speed of the train 25 km / h when the vehicle is received. Instructed to operate as described above, the wheel passage detection means 32 and the scratch detection means 33 are used to check the scratches on the wheel and transmit the result to the main computer 21.

And the wheel cutting controller 42 to control the wheel cutting device 41 to cut the scratched wheel.

First, the ground side inspection unit 10 shown in FIG. 1 will be described in detail.

Train number recognition means 11 of the ground side inspection unit 10 shown in Figure 1, as can be seen in Figure 2, each train (T) has a unique number as a magnet on the right or left side of the front vehicle An indexed license plate 110 is attached, and the license plate 110 has a structure that can be simply plugged into the side of the vehicle. When the train with the license plate 110 is operated, the sensor 111A, 111B) reads the binary code depending on the presence or absence of the magnet of the license plate 110.

For example, in the license plate shown in Fig. 2, since all are 1, the binary code is converted into decimal number and the value is 2047 (2 ¹⁰ +2 ⁹ +2 ⁸ +2 ⁷ +2 ⁶ +2 ⁵ +2 ⁴ +2 ³ +2 ² +2 ¹ +2 ⁰ ), and the train number is 2047. Herein, the magnet in the license plate 110 is illustrated as 11 bytes. However, the present invention is not limited thereto, and 12 to 16 bytes may be preferable in consideration of a route number and other unique numbers.

The train numbers entangled by the sensors 111A and 111B are amplified by the respective amplifiers 112A and 112B and input to the controller 14 in the ground side inspection unit 10. The sensors 111A and 111B and the amplifier Since (112A, 112B) is used twice, only data that is read repeatedly is recognized as official data.

When the train number is detected in this state, the train proceeds in the direction of the arrow in FIG. 3, and when the approach of the first wheel W1 is detected by the wheel passing sensor 121, the controller 14 detects the impact sound sensor 131 from the moment. And analyzes and stores the impact sound of the wheel W1 received from the vehicle. When the wheel W1 is detected by the first wheel pass sensor 121 and the second wheel pass sensor 122 installed at a distance of 1/2 of the circumferential length of the wheel wheel, the controller 14 detects the second impact sound. The impact sound at sensor 132 is analyzed and stored. This continues until the third wheel pass detection sensor 123 detects the wheel W1. Here, two impact sound detection sensors 131 and 132 are respectively installed between the wheel passage detection sensor 121 and the wheel passage detection sensor 122 and between the wheel passage detection sensor 122 and the wheel passage detection sensor 123, respectively. Data is collected, and the collected two data become the data of the first wheel W1.

At this time, the controller 14 analyzes two data, that is, whether the first wheel W1 is scratched and transmits the data to the main computer 21 through the modem MODEM1, and then transmits the data of the second wheel W2. Begin to analyze. Here, the data analysis method of the controller 14 is illustrated in FIG. 4, which will be described.

The waveform shown in FIG. 4 shows a wheel passing sensor 321, 322 as an example of a part of the first wheel W1 (when the wheel is divided into two and there are scratches in the first half, and there are no scratches in the second half). A1, C1, and E1 of the waveforms A, C, and E of 323 and 323 are related to the first wheel W1, and A2 of the waveforms of the wheel passing sensor 321, 322, and 323. , C2 is for the second wheel (W2) (here, the vibration of the waveform due to noise is omitted), as shown in the figure is a simple on / off waveform.

On the other hand, in the figure shown in Fig. 4, the waveforms B and D of the impact sound detection sensors 331 and 322 are waveforms which appear by scratches in the first half of the first wheel W1, and the waveform B1 is the first. This is because it is closest to the scratch detection sensor 331. The waveform B2 is the impact sound of the scratches caught in the waveform B1 by being rotated one turn. It is small in size because it is far from the scratch detection sensor 331.

However, the reason why the waveforms D1 and D2 of the scratch detection sensor 332 are very small compared to the waveform B1 is that only the first half of the first wheel W1 has scratches, and the first wheel W1. In the latter part of), it is assumed that there is no scratch, so there is almost no impact sound.

When the approach of the first wheel (W1) of the train is detected as described above, the impact sound of the wheel received from the impact sound sensor 331 is analyzed and stored from the moment, and then the circumference of the first wheel pass sensor 321 and the standard wheels. When the first wheel W1 is detected by the second wheel passing sensor 322 installed at a distance of 1/2 the length, the controller 14 analyzes and stores the impact sound from the second scratch detection sensor 332. To start. This continues until the third wheel pass detection sensor 323 detects the first wheel W1. Here, the two scratch detection sensors 331 and 332 are installed in the middle of each of the wheel pass detection sensors 321 and 322 and the wheel pass detection sensors 322 and 323 to collect data. Becomes the data of the first wheel W1.

The wheel data of the train No. 2047 to be examined is stored in the controller 14 and then, under the control of the main computer 21, via the modem MODEM1 via the modem MODEM2 at the inspection station. Can be sent to.

Therefore, the ground side inspection unit 10 installed on the ground side can transmit data on the wheels of all the trains to the main computer 21 about the real time or about once a day during the time when the train is running.

As shown in FIG. 1, the scratch data transmitted to the main computer 21 of the data analysis processing unit 20 is accurately analyzed and processed by the main computer 21, and is transmitted to the controller 34 of the vehicle inspection base inspection unit 30. If necessary, it is output by the monitor 23 or the printer 24 as graphics, characters, or the like.

On the other hand, the controller 14 of the inspection vehicle side inspection unit 30 selects the vehicle to be precisely analyzed based on the data received from the main computer 21, and then monitors it with the train number recognition unit 31 and wears the vehicle. When the train speed limit means 35 is instructed to drive the speed of the train to more than 25km / h, as shown in Figure 6, the wheel passage detection sensor (351, 352) of the train speed limit means 35 ) Is installed at a predetermined interval near the rail (R) in the inspection station to detect the passing of the wheel to detect the passing time between the two points to detect the speed of the train.

Accordingly, the wheel detection signals detected by these wheel passage detection sensors 351 and 352 are amplified by the amplifiers 353 and 354, respectively, and then input to the central processing unit 356 so that the speed of the train can be calculated. .

At this time, the central processing unit 356 checks whether the train speed is most suitable for the performance of the impact sound detection sensors 331 and 332 shown in FIG. 5 and checks the current train speed for wheel inspection of the train stored in the train speed memory 355. If the current train speed is out of the allowable range, the alarm signal is output. At this time, the speed command transmitter 358 provides the train speed control signal from the train speed calculation and control unit 356 to the train so that the engineer can maintain the speed of the train at the speed required by the wheel inspection apparatus.

Therefore, even if the engineer does not detect the allowable speed indication (for example, keep more than 25 km / h) for the section of the wheel inspection apparatus recorded on the allowable speed advance warning sign 359 shown in Fig. 6, the speed command transmitter By detecting the speed correction signal transmitted from 358 and maintaining the train at the above speed, it is possible to accurately inspect the scratches on the wheels.

Meanwhile, the inspection vehicle side inspection unit 30 shown in FIG. 5 is the same as the operation of the ground inspection unit 10 shown in FIG. 3 except for the train speed limiting means 35, and thus will be omitted.

If there is a scratch on the wheel, the main computer 21 compares the data received from the controller 14 of the ground inspection unit 10 and the data received from the inspection vehicle side inspection unit 30 to analyze the wheel cutting controller ( 42) to cause the wheel cutting device 41 to cut the scratched wheel.

As described above, the automatic wheel scratch inspection device according to the present invention, instead of manually inputting the train number to inspect the wheel scratches of the train on the ground side, it automatically checks the train number and the scratch state information of the wheels, It is possible to quickly analyze and store the wheel information of the train by sending the main computer, and train speed limit device is provided to know whether the train is operating at the specified speed for accurate inspection of the wheel at the inspection station. It is possible to eliminate the delay of inspection due to the repeated operation of the same train, and by linking the wheel information analyzed by the main computer with the wheel cutting device, it is possible to quickly cut the scratched wheels and to quickly introduce the train to the sales line. It works.
