Benefits of technology

The present invention aims to improve versatility by providing a condition monitoring device for a railway that can address various issues, making it more adaptable and useful.

Problems solved by technology

When the rails, the wheels, and the like of the railways are worn out and fail, there is a risk of affecting an operation of the railway vehicle.
In this case, maintenance man-hours and replacement materials are surplus, which is disadvantageous in terms of cost.
On the other hand, if the maintenance intervals are long, there is a high possibility of failure when the rails, the wheels, and the like are worn out faster than expected.

first embodiment

[0047]A railway condition monitoring device 20 (hereinafter, simply referred to as “condition monitoring device 20”) and a railway brake control device 80 (hereinafter, simply referred to as “brake control device 80”) according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG. 1 is a schematic diagram of a front view illustrating a railway vehicle 100. FIG. 2 is a schematic diagram illustrating the railway vehicle 100 as viewed from the side. FIG. 3 is a block diagram schematically illustrating a condition monitoring device 20 and a brake control device 80 according to the present embodiment. The condition monitoring device 20 and the brake control device 80 according to the present embodiment are mounted on the railway vehicle 100. In particular, the condition monitoring device 20 is mounted on the bogie 10 of the railway vehicle 100.

[0048]Each functional block illustrated in each drawing of the present disclosure including FIG. 3...

second embodiment

[0103]A railway condition monitoring device 20 and a railway brake control device 80 according to a second embodiment of the present invention will be described with reference to FIGS. 1, 2, and 6 to 8. The condition monitoring device 20 and the brake control device 80 according to the present embodiment are mounted on the railway vehicle 100. FIG. 6 is a block diagram schematically illustrating a condition monitoring device 20 and a brake control device 80 according to the present embodiment.

[0104]As illustrated in FIG. 6, the condition monitoring device 20 includes an acquirer 30, an information processor 40, a power supplier 70, and a position information acquirer 82. In addition, the brake control device 80 includes the acquirer 30, the information processor 40, and a brake controller 60. The information processor 40 includes a determiner 44, a storage 46, a transmitter 48, and a transmission controller 42. The acquirer 30 includes a vibration sensor 30b and a speed sensor 30c. ...

third embodiment

[0139]A railway condition monitoring device 20 and a railway brake control device 80 according to a third embodiment of the present invention will be described with reference to FIGS. 1, 2, and 9 to 12. The condition monitoring device 20 and the brake control device 80 according to the present embodiment are mounted on the railway vehicle 100. FIG. 9 is a block diagram schematically illustrating a condition monitoring device 20 and a brake control device 80 according to the present embodiment.

[0140]Brake squeal may occur when the contact brake 18d is operated. The brake squeal is an abnormal noise in which vibration from a friction surface caused by a touch of a brake shoe 18b to a braking member 18c during braking is amplified and generated by the brake shoe 18b or the braking member 18c, and is called braking noise. The brake squeal occurs due to the wear or the like of the friction surface of the brake shoe 18b and the braking member 18c. If the brake squeal occurs, the brake sho...
