Description

[0001] The present invention relates to an individual control type heating system for a railway vehicle,

More particularly, the present invention relates to an individual controlled heating system for a railway vehicle, and more particularly, to a system for heating a whole interior of a vehicle from a floor to keep the interior in a comfortable state and minimizing energy lost during regenerative braking or operation To an individual controlled heating system for a railway vehicle, which can reduce energy waste and quickly compensate for a temperature imbalance inside a vehicle when a door is opened.

Unlike ordinary chairs, chairs for electric trains installed on urban railways and wide railway vehicles are characterized by long chairs of about 3 to 7 people installed parallel to the direction of the vehicle. Chairs for electric trains are an important part of customer satisfaction because they directly affect the comfort of passengers.

In addition, a conventional heating apparatus for a train is generally an electric heater installed in a lower portion of a chair for a train, and generally takes the form of a tubular heater using a heat wire. Maintaining a proper heating temperature has a direct effect on the comfort and temperature maintenance of the passengers during the winter season, and the energy used for heating is up to one-fifth of the power consumption of the winter train, saving energy and ensuring the comfort of passengers. There is a high need for heating.

However, since conventional railway heating apparatuses generate heat intensively at the heater under the chairs on both sides of the electric train, the generated heat is not directly transmitted to the passengers but rises on the side of the electric train through the convection, The temperature in the central bottom of the room is relatively low, so that the temperature distribution in which the human body feels a thermal comfort feeling as much as the temperature of the head side is up to 5 degrees Which is uncomfortable to passengers. This is solved when the heating device is turned on for a long time after the heating operation is started. However, in the case of the train operation, the temperature inside the vehicle is lowered as the door is opened and the above phenomenon is repeated. Accordingly, increasing the output of the heater to quickly supply heat to the center of the vehicle increases the power consumption and gives the passengers who are seated in the seat discomfort due to the heat.

In view of such problems, there is a need for a heating device for a train that not only supplies heat while reducing power consumption, but also provides a passenger with a sense of thermal comfort.

Meanwhile, the control method of the conventional railway heating system includes a manual mode in which one of 350W, 700W and 1050W is selected through TCMS or a switch or an automatic mode in which heating and cooling is operated in accordance with a temperature range, Respectively.

Such a heating device operates as set up regardless of the operating state of the train, such as whether it is operating or regenerative braking power available, so that there is a problem that the energy that is not used is wasted.

FIG. 4 is a view showing a state in which each heat generation module of the floor heating unit is controlled according to the calculation result of FIG.

The present invention relates to an individual controlled heating system for a railway car. As shown in FIGS. 1 to 6, the present invention includes a chair heating unit 100 for heating a chair portion of a railway vehicle, a floor heating unit A controller 300 for controlling the chair heating unit 100 and the floor heating unit 200 and a train control system 300 for controlling the controller 300, , 400).

2, the chair heating unit 100 includes a heat generating module 110 provided inside a seat, a back, and a side portion of a chair, and the heat generating module 110 as a seat, a back, And a bracket 120 for fixing the inside thereof.

3, the heat generating module 110 includes a heat insulating layer 112 for preventing the heat from leaking in a direction opposite to a passenger in the seat, the back, or the side surface, and a heat insulating layer 112 And a heat radiating layer 116 provided on the other side of the heat generating layer 114 to radiate heat in a passenger direction.

Here, the heating layer 114 is formed of a carbon fiber surface heating element or a heat-generating woven fabric including carbon heating wire, and is resistant to impact and deformation, has a small heat capacity and can quickly reach a target temperature and is excellent in high temperature durability.

In addition, the heat insulating layer 112 allows the heat generated in the heat generating layer 114 to be diverted only toward the passenger. The material of the heat insulating layer 112 uses inorganic heat insulating material such as glass wool to improve the incombustibility.

Since the body of the passenger directly contacts the heat dissipation layer 116, the heat generated from the heat dissipation layer 114 is uniformly diffused toward the passenger using a heat dissipation material such as graphite which is not too hard.

4, the heat generating module 110 may be provided on both the seat, the back, and the side portion of the chair, and may be installed only on the seat, .

In this case, when the heat generating module 110 is installed on the side portion, since the doors and the side portions of the respective vehicles are adjacent to each other, the external cold air introduced through the doors is prevented by the heat generating module 110 So that the passenger can move to a more comfortable state.

Although the heat generating modules 110 may be connected in series in the drawing, the heat generating modules 110 may be connected in parallel so as to control the heat generating modules 110 through the controller 300, instead of being connected in series.

As shown in FIGS. 5 and 6, the bottom heating unit 200 includes a plurality of heating modules 210 installed inside the bottom of the vehicle. As shown in FIG.

The heat generating module 210 includes a heat insulating layer 212 for preventing the heat from leaking toward the bottom of the vehicle where the passenger is not located and a heat insulating layer 212 provided on one side And a heat-radiating layer 216 provided on the other side (i.e., upper side) of the heat-generating layer 214 to radiate heat in a passenger direction.

At this time, the heat generating module 210 is fixed to the upper part of the vehicle structure 220 constituting the vehicle, and the skin layer 230 is provided on the heat generating module 210, Which prevents the inflow of water flowing into the vehicle into the heat generating module when rain or snow comes in.

Since the heat insulating layer 212 and the heat generating layer 214 are made of the same material as the material of the chair heating part 100 and the heat dissipating layer 216 must withstand the load of many passengers, And the heat is transferred evenly to the upper part where the passenger is located.

If the heat generating module 210 is installed on the entire inner bottom of the vehicle as in the present invention, the heat is evenly distributed to the upper part of the floor as shown in FIG. 7 (b) .

That is, as shown in FIG. 7 (a), a heating device is provided only on a chair portion provided on both sides of the vehicle, so that the heat is moved to the upper portion of the wall surface, So that the passengers feel uncomfortable. However, in the present invention, since the heat generating module 210 is provided on the entire floor, heat is uniformly distributed throughout the room, thereby minimizing the temperature unbalance.

On the other hand, the train control management system (TCMS) 400 judges whether the train is operated for business operation or non-business operation according to a train number pattern assigned to the train.

Here, since the train number is different from the train number for business operation and the train number for non-business operation, it is possible to determine the purpose of train operation according to the pattern.

At this time, the train control system (TCMS) 400 controls the operation of the chair heating unit 100 and the floor heating unit 200 so that the passenger can move in a warm condition The controller 300 controls the chair heating unit 100 and the floor heating unit 200 not to operate because the passenger is not boarded when the controller 300 determines that the vehicle is in the non-business operation mode.

That is, when the train control system (TCMS) 400 is in the operating mode, the room heating interrupter auxiliary relay (RHeCOAR) is turned off and the room heating interception relay (RHeCOR) is turned on in the circuit shown in FIG. The room heater contactor RHeK is energized to supply electric power to the chair heating unit 100 and the floor heating unit 200. In the case of non-business operation, the room heater interrupting auxiliary relay RHeCOAR is energized, (RHeCOR) to block the room heater contactor (RHeK), thereby cutting off power supply to the chair heating unit 100 and the floor heating unit 200.

Accordingly, in the present invention, it is determined whether the driving purpose of the railway vehicle is a business operation or a non-business operation, so that the chair heating part 100 and the floor heating part 200 are not operated when there is no passenger, thereby reducing energy consumption.

Meanwhile, the train control system (TCMS) 400 senses the state of the railway vehicle and operates the chair heating unit 100 and the floor heating unit 200 at a maximum output power in a regenerative braking state .

Here, the railway vehicle is provided with a regenerative current sensing relay (CDR) that operates when the regenerative current is equal to or higher than a constant current in order to normally determine regenerative braking during regenerative braking. The Train Control Management System (TCMS) When the regenerative current sensing relay (CDR) constituting the circuit shown in FIG. 1 operates, it is determined that the regenerative braking is performed.

At this time, the railway car is provided with a switch (CHCgS) 410 for controlling the output for heating the room according to the external temperature. The switch (CHCgS) 410 includes two switches (CHCgS, 410 And controls the opening and closing of the switches CHCgS and 410 to adjust the output in three steps of 350W, 700W and 1050W.

Accordingly, when the TCMS 400 senses the regenerative braking state, the TCMS 400 controls both of the switches CHCgS and 410 to operate at 1050 W, (RHeK1, RHeK2) to the first and second room heater contacts (SIV) so that both the first and second room heater relays (RHeR1, RHeR2) are operated and the maximum output (1050W) .

The controller 300 is also supplied with information on the regenerative braking state so that the chair heating unit 100 and the floor heating unit 200 can be operated at the maximum output even if the temperature rises above the set temperature Respectively.

However, when the temperature of the controller 300 rises above the set temperature, a limit value for the difference from the set temperature is set, so that even though the control is performed in the train control management system (TCMS) 400 When the temperature rises above the threshold value, the current supplied to the chair heating section 100 and the floor heating section 200 is limited to reduce the heat generation amount, thereby allowing the passengers to move in a comfortable state.

At this time, a temperature sensor (not shown) is provided in each of the heat generating modules 110 and 210 constituting the chair heating part 100 and the floor heating part 200, so that each temperature can be sensed.

The train control system (TCMS) 400 measures the heat loss in the vehicle interior due to the external cold air when the doors of the railway vehicle are opened, through the heat loss compensation function (Equation 1) The degree of compensation is calculated.

Equation 1:

{W _adj: the output of the compensation heaters, W: prior to compensate heating output, T: train-car temperature, T _amb: train outside temperature, t _close: the door after the closed elapsed time, t _open: opened the door _Dxn is the x coordinate of the center point of the door d _yn is the y coordinate of the center point of the door c is the width of the door x is the x coordinate of the heating device y is the y coordinate of the heating device k is the compensation coefficient}

The controller 300 controls the number of the heating modules 210 constituting the bottom heating unit according to the degree of compensation calculated through the heat loss compensation function (Equation 1) in the train control management system (TCMS) Respectively.

That is, when the railway vehicle is stopped and the door is opened, the cold air of the outside flows into the interior of the vehicle through the door, thereby generating heat loss as shown in FIG. 8. The TCMS System 400 calculates the heat loss and the degree of compensation according to the heat loss compensation function, and an example thereof is shown in FIG.

The controller 300 controls each of the heat generating modules 210 provided on the floor of the vehicle as shown in FIG. 10 according to the degree of compensation, so that a portion close to the door operates at a high temperature, And operate at a low temperature to compensate the heat loss as much as possible, so that the temperature imbalance inside the vehicle can be quickly resolved.

While the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the scope of the present invention is not limited to the disclosed embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.

More particularly, the present invention relates to an individual controlled heating system for a railway vehicle, and more particularly, to a system for heating a whole interior of a vehicle from a floor to keep the interior in a comfortable state and minimizing energy lost during regenerative braking or operation To an individual controlled heating system for a railway vehicle, which can reduce energy waste and quickly compensate for a temperature imbalance inside a vehicle when a door is opened.
