Abstract: Provided is a method for multi-supplying gas, the method comprising: installing a control valve and an flow meter on each of a plurality of branch lines branched from a main supply line, in which one or more gases are supplied, and supplying the gas; and providing the gas by adjusting flow of the gas by a controller connected to each of the control valve and the flow meter, wherein the controller has a first control manner, which controls each of the control valves based on a rate of flow measured by the flow meter to required portion flow for each branch line, and the first control manner adjusts an open rate of the control valve if the rate of the measured flow to the required portion flow is not within a predetermined range, and a unit of adjusting the control valve increases or decreases according to a difference between the measured flow and the required portion flow.

Abstract: Disclosed is a brake HILS system for a railway vehicle, comprising: a user terminal that receives values relating to braking conditions of a railway vehicle through a user interface and monitors simulation results; a pneumatic brake that includes an electronic control unit, a brake operation unit, a wheelset, a brake caliper, and a wheel slide protection valve and produces pneumatic pressure and transmits a braking force to the wheelset in accordance with the braking conditions from the user terminal; a load cell that is disposed on a wheel or a disc and measures a braking force from the pneumatic pressure; and a modeling unit that simulates the running and braking dynamic characteristics of a railway vehicle in real-time using mathematical models.
