As an example, the plurality of pipes 111 and 112 may be fire extinguishing pipes having a diameter of 40 mm (or 65 mm) and may be sprinkler fire extinguishing pipes and may be connected to a fire hydrant or the like. Each of the plurality of pipes 111 and 112 may include an iron pipe (not shown) through which fluid (e.g., water) flows in the inner space, and a thermal insulating material (not shown) surrounding the pipe. The plurality of pipes 111 and 112 may be variously changed within a range known to a person skilled in the art. The plurality of pipes 111 and 112 are well known to those skilled in the art, and a detailed description thereof will be omitted.

As shown in FIG. 1, the plurality of heating lines 121 and 122 can be installed in a spiral shape while enclosing the plurality of pipes 111 and 112. When power is supplied through the power line 150 Heat can be generated. The plurality of heating lines 121 and 122 may be formed of a heating element such as a nichrome wire (or a constant temperature wire or a heating cable) that generates heat when power is supplied thereto. The heating elements may be various types of heating elements Lt; / RTI > For example, the plurality of heating wires 121 and 122 can consume 16W / meter, and when the temperature is lowered, the power supply can be increased and the initial power can be supplied more than 16W. The plurality of heating lines 121 and 122 may be changed to a heating line having a power consumption (heating value) of 10 W or 24 W depending on the diameter (diameter) of the plurality of pipes 111 and 112. As is known to those of ordinary skill in the art, as the calorific value of the plurality of heating lines 121 and 122 increases, the time required to raise the temperature of the pipes 111 and 112 provided with the plurality of heating lines 121 and 122 may be further shortened have.

As shown in FIG. 1, the plurality of piping temperature sensors 131 and 132 are attached to the outside of a plurality of pipelines 111 and 112, or installed in a thermal insulation material that surrounds the outside of the steel pipe, . The plurality of piping temperature sensors 131 and 132 can measure the piping temperature of the corresponding piping and output the piping temperature measurement values to the plurality of individual controllers 141 and 142. The plurality of piping temperature sensors 131 and 132 can not accurately measure the piping temperature due to heat emitted from the plurality of heating lines 121 and 122 when the plurality of piping temperature sensors 131 and 132 are installed close to the plurality of heating lines 121 and 122 The plurality of piping temperature sensors 131 and 132 are disposed on opposite sides of the respective heating lines 121 and 122 with reference to the center of each of the pipes 111 and 112 so as not to overlap with the plurality of heating lines 121 and 122 As shown in FIG.

The power line 150 can transmit the power supplied from the integrated controller 180 to the plurality of heating lines 121 and 122 through a plurality of individual controllers 141 and 142. [ 1, a home heating line control system 100 according to an exemplary embodiment of the present invention includes a plurality of heating lines 121, The total amount of power supplied to the plurality of heating lines 121 and 122 can be dispersed under the control of the integrated control device 180.

That is, the reference temperature for power supply to the plurality of heating lines 121 and 122 and the power supply cut-off may be set to the first reference temperature and the second reference temperature, respectively. As an example, the first reference temperature may be set to 0 占 폚, and the second reference temperature may be set to 4 占 폚. The second reference temperature may be set in consideration of safety or an error between the plurality of pipes 111 and 112 and the gap between the plurality of heating lines 121 and 122 or the plurality of pipe temperature sensor units 131 and 132 It may be set to a value within a range of 5 ° C to 10 ° C.

3 is a flow chart illustrating a heating line control method according to an embodiment of the present invention. The heating line control method shown in FIG. 3 can be performed by the integrated control devices 180 and 280, particularly, the heating line control unit 283 of the apartment house heating line control system according to the present invention.

Referring to FIG. 3, the heating line control method may include (S31) monitoring the pipe temperature measurement values of a plurality of pipes. As described above with reference to FIG. 2, the heating line control unit 283 receives the pipe temperature measurement values measured by the plurality of pipe temperature sensor units 231 through a plurality of individual controllers 240, have. The monitoring period may be set according to an external temperature or may be set by an administrator.

Next, the heating line control method shown in Fig. 3 may include a step (S32) of supplying power to a heating line corresponding to the pipe whose pipe temperature measurement value is equal to or lower than the first reference temperature. That is, when there is a pipe temperature measurement value that is equal to or lower than the first reference temperature among the pipe temperature measurement values input from the plurality of individual controllers 240, the heating wire control unit 283 controls the electric power for supplying power to the heating wire corresponding to the pipe Transmission control signals can be generated and transmitted to a plurality of individual controllers 240. [ The plurality of individual controllers 240 can control the power supply to the plurality of heating lines 221 by controlling the power transfer switch unit 243 in accordance with the received power transfer control signal.

Next, the heating line control method shown in FIG. 3 includes a step (S33) of cutting off the power supply to the heating line corresponding to the pipe when the pipe temperature measurement value of the pipe supplied with power reaches the second reference temperature can do. That is, when the pipe temperature measurement value is equal to or higher than the second reference temperature, the heating wire control unit 283 determines that the pipe temperature has become sufficiently high that the water flowing in the pipe is not frozen, and cuts off the power supplied to the heating wire corresponding to the pipe Thereby reducing power consumption.

As described above with reference to FIG. 1, the heating line control method performed in the apartment building heating line control system according to the present invention determines the power supply priority order of a plurality of pipes according to the order of low pipe temperature measurement values, Power can be supplied to the plurality of heating lines according to the power supply priority order.

4 is a flowchart illustrating a heating line control method according to another embodiment of the present invention. The heating line control method shown in FIG. 4 can be performed by the integrated control devices 180 and 280, particularly, the heating line control unit 283 of the apartment house heating line control system according to the present invention.

Referring to FIG. 4, the heating line control method may include a step (S41) of monitoring a pipe temperature measurement value of a plurality of pipes. As described above with reference to FIG. 2, the heating line control unit 283 receives the pipe temperature measurement values measured by the plurality of pipe temperature sensor units 231 through a plurality of individual controllers 240, have. The monitoring period may be set according to an external temperature or may be set by an administrator.

Next, the heating line control method shown in Fig. 4 may include a step (S42) of cutting off the power supply to the heating line corresponding to the pipe whose pipe temperature measurement value is equal to or higher than the second reference temperature. That is, when the measured value of the pipe temperature is equal to or higher than the second reference temperature, the heating line control unit 283 determines that the heating is not necessary any more and the power supplied to the heating line corresponding to the pipe is cut off, can do.

Next, the heating line control method shown in Fig. 4 includes a step (S43) in which the heating line control unit 283 determines whether the number of pipes whose pipe temperature measurement values are equal to or less than the first reference temperature is equal to or less than the maximum simultaneous heatable number . Here, the maximum simultaneous heatable number may be determined according to the maximum transmission capacity of the main power line 250 as the maximum number of heating lines through which the power supply unit 281 can simultaneously supply power through the main power line 250. For example, when the power consumption of each of the plurality of heating lines included in the heating system of the apartment heating line control system according to the present invention is 10 kw and the maximum transmission capacity of the main power line 250 is 50 kw, the maximum number of simultaneous heat generations can be 5 . On the other hand, the administrator may set the maximum number of simultaneous heat generations to a value smaller than 5 through the management terminal 290. [

Next, in the heating line control method shown in FIG. 4, when the number of pipes whose pipe temperature measurement value is equal to or less than the first reference temperature is equal to or less than the maximum simultaneous heatable maximum number (S43 -> YES) (S44) of supplying power to the heating line corresponding to the piping.

That is, when the number of pipes whose pipe temperature measurement value is less than or equal to the first reference temperature is less than or equal to the maximum simultaneous heatable maximum number, power can be supplied to all the heating lines corresponding to the pipes whose pipe temperature measurement value is equal to or less than the first reference temperature Therefore, the heating wire control unit 283 can supply power to the heating wire corresponding to the pipes whose pipe temperature measurement value is equal to or less than the first reference temperature. Meanwhile, as shown in FIG. 4, the heating line control method according to another embodiment of the present invention may perform step S41 after performing step S44.

Next, in the heating line control method shown in FIG. 4, when the number of pipes whose pipe temperature measurement values are equal to or less than the first reference temperature is greater than the maximum simultaneous heatable maximum number (S43 -> NO) And supplying power to the heating line corresponding to the selected pipes according to the maximum number of simultaneous heat generations (S45).

That is, when the number of pipes whose pipe temperature measurement value is equal to or less than the first reference temperature is greater than the maximum simultaneous heatable maximum number, the pipe temperature measurement value corresponds to the pipes that are below the first reference temperature due to the limitation of the maximum transmission capacity of the main power line Since it is not possible to supply power to all of the heating lines, it is possible to select the maximum number of pipes that can be simultaneously heated according to the order of lower piping temperature measurement values, and supply power to the heating lines corresponding to the selected piping.

For example, if the first reference temperature is 0 ° C and the maximum number of simultaneous heatable temperatures is 3, and the piping temperature measurements for pipes A, B, C, D, and E are -2 ° C, -1.5 ° C, B, C, and D, the piping temperature measurement value is less than the first reference temperature. However, since the maximum number of simultaneous heat generation is three, the piping A, B, C, and D It is not possible to supply power to all the heating lines, and power can be supplied only to the heating lines of three pipes, that is, the pipes A, B, and C, in the order of lower piping temperature measurement values. Of course, in this case, power is not supplied to the heating line even though the piping temperature measurement value is below the first reference temperature. However, when power is supplied to the heating lines of the pipes A, B and C, The pipe temperature measurement value of the pipe D becomes lower than the pipe temperature measurement values of the pipes A, B and C when the pipe temperature measurement values are monitored in the step S41 to be performed again after performing the step S45, Power can be supplied to the heating wire.

Therefore, the heating control system for the apartment house according to the present invention can reduce the number of heating lines supplied at the same time by the heating line control method as described above, thereby reducing the maximum instantaneous power consumption (peak power) .

2, the first reference temperature and the second reference temperature may be changed by the management terminal 290, and the external temperature measurement value and the plurality of It can be changed automatically according to the number of piping. Further, the heating wire control method according to the present invention can be terminated by an administrator's control at any time performed by the heating wire control unit 283.

Meanwhile, the heating line control method described above with reference to FIGS. 3 to 4 may be performed by a computer-readable recording medium on which a program for performing the heating line control method is recorded.
