The present invention relates to a passenger room lamp control system of a railroad car through an illumination sensor and an Ethernet and, more particularly, to a control system capable of brightness of an indoor lamp of various railroad cars automatically, semi-automatically, or manually by applying an illumination sensor and Ethernet communication scheme. The passenger room control system of a railroad car through an illumination sensor and an Ethernet comprises a plurality of passenger room lamps including a plurality of units formed of a plurality of light emitting diode (LED) modules installed in a room of a railroad car and adjusting brightness of the units formed of the LED modules according to an illumination control command, an illumination sensor installed in a front head section of the railroad vehicle to measure an illumination value of outside of the railroad vehicle, a train control management system (TCMS) transmitting a passenger room lamp brightness value set using a touchscreen of a monitor in a semi-automatic mode to a dimming controller through Ethernet communication, the dimming controller determining a passenger room lamp brightness value as an illumination value measured by the illumination sensor, generating an illumination control command, and transferring the generated illumination control command to a passenger room lamp in an automatic mode, generating an illumination control command with a passenger room lamp brightness value set in the TCMS and transferring the generated illumination control command to a passenger room lamp through Ethernet communication in a semi-automatic mode, and controlling a brightness value of a passenger room lamp through a knob switch provided therein in a manual mode, and an Ethernet hub provided between the dimming controller and the passenger room lamp to perform Ethernet communication. |
