Description

[0001] The present invention relates to a passenger room lamp control system,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control system such as an illuminance sensor and a railway car cabin via Ethernet. More particularly, the present invention relates to a control system that can automatically, semiautomatically or manually adjust the brightness of various railway car interior lamps using an illuminance sensor and an Ethernet communication system .

Conventional railway vehicles operate all fluorescent lights in the room during day / night driving.

Although it is not possible to change the brightness of a fluorescent lamp in a room where a railway car mainly operates in the underground section, in the case of a daytime, in the case of a weekday, all of the rooms are turned on at full brightness, and even if there is no great inconvenience to passengers, Because it is turned on and running, power consumption is wasted due to excessive use of the room, etc., and its life is shortened, so frequent replacement is required.

Also, in the case of a railway vehicle such as a train or an electric train, the lighting such as a room is controlled so as to be turned on / off at a time in the cab.

However, in the conventional control system such as a room, there is no method other than ON / OFF method of power supply for controlling lighting of a room or the like collectively in the cab.

In the case of a train in which a plurality of vehicles are connected, only all the rooms are turned on and off at the same time.

In order to prevent the waste of the power source when the power is turned off by the control method such as another room, a selective lighting method is used.

In this method, all the power is used through the battery when the power is cut off. In order to conserve the charge amount of the battery, the room lighting is turned on without lighting all of the rooms.

However, this method was also uncomfortable, and there were many inconveniences because there was no means to control the illuminance according to the operating conditions (ground or underground), weather, climate or surrounding conditions.

In the prior art patent document No. 10-1143533, when the driver of a train rotates a volume switch provided in the cab, the controller generates a control signal in order to match the illuminance of the cabin with the reference value set according to the amount of displacement of the rotation, There is disclosed a technique in which one or a plurality of converters mounted in respective rooms adjust the illuminance of a room or the like in accordance with the control signal, that is, the illuminance of the guest room can be controlled autonomously in the cab.

However, this prior art also has a problem that the driver of the train has to adjust the illuminance of the room by artificially rotating the volume switch in the cab.

Brightness control of guest rooms and the like through Ethernet is excellent in scalability of a device than a brightness using a conventional serial communication, and a communication speed is fast.

That is, the serial communication is relatively slow in the communication speed compared with the Ethernet, and is unidirectional communication, so that the speed of the brightness adjustment is not made simultaneously for each vehicle.

For example, when using the serial communication, when the brightness of the front car and the rear car is adjusted to be dark or bright, the time difference may be large depending on the size of the combination, and it may act as an obstacle to the passenger's sensitivity quality. It is possible to dramatically improve the communication speed.

Generally, the illuminance sensor 10 is installed at the front of the vehicle, detects the amount of light when the vehicle is traveling, measures the illuminance value outside the vehicle, and outputs the illuminance value to the dimming controller 20 connected to the illuminance sensor 10.

At this time, one or more reference illuminance values are previously set in the dimming controller 20, so that it is possible to compare the measured illuminance values measured by the illuminance sensor 10 and determine the brightness value of a room or the like according to the comparison result.

For example, when the first reference illuminance value and the second reference illuminance value are set as the reference illuminance value in the dimming controller 20 (the first reference illuminance value <the second reference illuminance value) The dimming controller 20 determines the brightness value of the room or the like to be the maximum brightness value (100%). If the measured illuminance value is less than the first reference illuminance value and the second reference illuminance value The dimming controller 20 determines the brightness value of the room or the like to be 1/2 (50%) of the maximum brightness value. If the measured illuminance value is larger than the second reference illuminance value ( The dimming controller 20 can determine the brightness value of the room or the like to be 1/5 (20%) of the maximum brightness value.

In the case of semi-automatic mode, the dimming controller 20 sets the room brightness value through the touch screen of the TCMS monitor unit in consideration of the external environment and the operating conditions of the ground / underground section in the case of the semi-automatic mode, , The brightness of the room is adjusted by the brightness value such as the room set through the Ethernet communication with the guest room and the like.
