Abstract
Provided are a brake system, a brake device, and a method of controlling brakes for railroad cars in which control can be multiplexed with a simple configuration. In a brake system 1 for railroad cars includes brake control devices 11, 12, 13 provided in railroad cars 101, 102 103 respectively that form a unit 104. Each brake control device 10 (11, 12, 13) is capable of outputting information of the corresponding car (101, 102, 103) to the other brake control devices 10 through a transmission device 20. The brake control device 10 can calculate a total necessary braking force value BRA required for braking all of the cars 101, 102 103 using the information output from the other brake control devices 10 to the transmission device 20.
Claims21
A brake system for railroad cars that form a unit, comprising:
- brake control devices, each brake control device being provided in a corresponding one of the railroad cars,
- wherein each of the brake control devices is configured to output information about the corresponding railroad car in which the brake control device is provided to the other brake control devices through a transmission device,
- wherein each of the brake control devices is also configured to calculate a total necessary braking force value by using the information output from the other brake control device(s) to the transmission device, the total necessary braking force value being required for braking all of the railroad cars forming the unit,
- wherein each of the brake control devices is configured to, upon receiving a deceleration command signal, calculate a necessary braking force that is required for braking the corresponding car and output the necessary braking force value as the information to the transmission device, and
- wherein each of the brake control devices is configured to calculate the total necessary braking force value by adding the necessary braking force values calculated by the other brake control devices to the necessary braking force value that is required for braking the corresponding car.
A method of controlling brakes on railroad cars forming a unit, comprising:
- outputting, by each of brake control devices provided in a corresponding one of the railroad cars, information about the corresponding railroad car in which the brake control device is provided through a transmission device to the other brake control devices;
- calculating, by each of the brake control devices, a total necessary braking force value by using the information output from the other brake control devices to the transmission device, the total necessary braking force value being required to put for braking all of the railroad cars forming the unit;
- calculating, upon receipt of a deceleration command signal by each of the brake control devices, a necessary braking force that is required for braking the corresponding railroad car and outputting the necessary braking force value as the information to the transmission device;
- and
- calculating, by each of the brake control devices, the total necessary braking force value by adding the necessary braking force values calculated by the other brake control devices to the necessary braking force value that is required for braking the corresponding railroad car.
