Description

An automatic abnormality Detectingy system of Railroad Cars}

The present invention relates to an automatic daily inspection device for trains, and more particularly, trains that enable integrated management of information on abnormalities of the entire vehicle, including wheels, pantographs, braking units, and air conditioning equipment. It relates to an automatic routine inspection device.

Trains such as subways and trains use electric energy as a power source, and in order to supply such electric energy, electricity flowing through the electric supply line is installed by installing an electric supply line on the railway and installing a pantograph in contact with the electric supply line. To be supplied to the electric car.

Since the electric vehicle runs at high speed, friction between the pantograph and the electric supply line occurs, and the friction causes wear of the current collector plate, which is the contact portion between the pantograph and the electric supply line.

As the train continues to run, the current collector plate will continue to wear out, and eventually the current collector plate will wear out and the train will not be able to receive electricity.

Therefore, the current collector plate of the train must be replaced after a certain running time. For this replacement work, the train manager must go up the roof of the train at any time to check the wear level of the current collector plate, and when and which trains are checked continuously. You must manage it.

However, it is very cumbersome and inconvenient for the manager to climb on the roof of the train and check the wear state of the current collector plate. Since the wear level is different for each train, it also takes a lot of time and manpower to manage which train and when to check. Shall be.

In addition, in electric cars such as subways and trains, scratches on wheels generated as a result of friction between the wheels and the road surface during driving, especially during braking, are not only deteriorating ride comfort, but also becoming a major factor in generating loud noise. Therefore, it is necessary to quickly inspect the scratches on these wheels and replace the wheels of the train or upgrade the previously recorded information.

After recognizing and discriminating only from the obtained image, the image is transmitted to the fourth appearance decision controller 154. The heat generation recognition unit 149 determines the image photographed by the heat sensing camera and transmits the image to the fifth appearance determination controller 155.

As described above, the first to fifth appearance determination controllers 151, 152, 153, 154, and 155 analyze the transmitted and stored image data to determine whether there is an abnormality (breakage, crack occurrence, contamination, etc.), abnormal lighting, abnormal door, abnormal display. It is determined whether or not, overheating, etc., and the determined and processed information is transmitted to the integrated management unit 200 through the third data transmission unit 156.

Next, when the train vehicle approaches the braking unit abnormality detecting unit 160, the train is recognized by the train number recognition unit 141.

Next, when the wheel passage is recognized by the wheel passage recognizing unit 162, the wheeled vehicle abnormality determination control unit 171 and the disc abnormality determination control unit 172 are initialized, and at least one of the determination control units 171 and 172 is a digital image detection unit. In operation 163, the wheel part is photographed to photograph the wheelbarrow and the disc lining part to obtain an image. The digital image detector 163 receives the command to obtain the image. The captured images are transmitted to and stored in each of the wheeler abnormality determination controller 171 and the disk abnormality determination controller 172. At this time, the image transmitted to and stored in each of the wheel failure problem determination controller 171 and the disc failure determination controller 172 may be the same image. That is, by acquiring images by capturing both the wheelbarrow and the disc lining part, it is possible to reduce the equipment and data processing speed by classifying or separating and classifying the video of the wheelbarrow part and the disc lining part. .

When it is recognized that all of the trains have passed, the wheeled wheel abnormality determination control unit 171 determines whether or not the wheeled wheel abnormality and transmits to the integrated management unit 200 through the fourth data transmission unit (173). The disk abnormality determination control unit 172 also determines whether the disk lining is abnormal and transmits it to the integrated management unit 200 through the fourth data transmission unit 173.

In addition, when the vehicle is close to the air conditioner abnormality detection unit 180, the vehicle number is recognized by the train number recognition unit 181.
