Description

Heating Control System for Multi-Housing and Heating Control Method using Return Water Temperature

The present invention relates to a heating control system for a multi-family house and a heating control method using a return temperature.

A district heating system and an individual boiler system are largely used for heating systems in apartment houses.

The district heating method is a central heating method in which medium hot water above a specific temperature (for example, about 110 degrees Celsius) is supplied to the machine room provided in the apartment house, and medium hot water from the machine room is supplied to each household. The boiler method is an individual heating method in which a boiler is provided for each household in an apartment house, and the boiler heats the heating water and supplies it to the individual rooms of each household.

Meanwhile, in both the district heating method and the individual boiler method, the temperature of each individual room is controlled through the thermostat provided in each household.

Each room valve controller is wirelessly connected to the main room con and each room con, and unnecessary wiring is removed, thereby increasing the convenience of installation. can be controlled

However, compared with wired communication, wireless communication has a lower quality or transmission speed of data transmission, and there is a high possibility that an error in data transmission occurs due to obstacles provided in each generation. That is, Korean Patent Document No. 10-1448300 discloses that, when a failure occurs in the wireless communication process, it is difficult to control each valve.

In particular, in the case of an apartment house, it is important to control the temperature measured by the temperature sensor provided in the individual room to match the temperature set in the main thermostat for controlling the heating temperature of the individual room. For example, the temperature measured by the temperature sensor is transmitted to a sub temperature controller provided in a private room, the sub temperature controller transmits the measured temperature data to the main temperature controller through wireless communication, and the transmitted temperature data and the main temperature controller A heating system that controls the temperature set to match may be applied.

However, when a failure occurs in wireless communication, the temperature of the individual room cannot be transmitted, so that the heating temperature of the individual room is not controlled to match the temperature set by the main temperature controller.

Accordingly, in the heating system, even if a wireless communication failure occurs, a system in which the heating temperature of an individual room is controlled to match the set temperature is required.

In another example, a heating controller module (not shown) including a communication module 71 , an RF IoT communication module 72 , a learning module 74 , a query input unit 75 and an output unit 76 of the heating controller 70 ) A configuration including a communication module provided on the wall pad and communicating with a heating controller module (not shown) and a heating control unit 73 may be installed in the space where the distribution unit 10 and the water return unit 20 are installed. have. Accordingly, the command input to the wall pad is transmitted to the heating controller module (not shown), and it is also possible to control heating by being transmitted to the heating control unit 73 through the heating controller module (not shown).

Since the information transmitted to the heating controller 70 includes a unique individual room temperature control unit ID, the individual room temperature control unit 50 that has transmitted the information among the plurality of individual room temperature control units 50 is specified. it is possible to do

The heating controller 70 includes a communication module 71 for wired communication with the main temperature control unit 60 , an RF IoT communication module 72 for wired communication with the individual room temperature control unit 50 , and a boiler (2).

It may be a data pair consisting of the temperature of the individual room, which is the level of the second input temperature signal output from the .

The temperature of the individual room is related to the temperature of the hot water passing through the heating line (L), and thus is also directly related to the temperature of the returned water flowing through the heating line (L) and flowing into the water return unit (20). Therefore, if the temperature of the return water is known, it is possible to infer the temperature of the individual room inversely.

The learning module 74 learns a plurality of data consisting of a data pair of the water exchange temperature and the temperature of the individual room accordingly. In an example, the data pair is trained on an artificial neural network (ANN) model, wherein the artificial neural network model is a Deep Neural Network (DNN), a Convolutional Neural Network (CNN), a Deep Convolutional Neural Network (DCNN), or an RNN ( It may be a model based on Recurrent Neural Network), Restricted Boltzmann Machine (RBM), Deep Belief Network (DBN), Single Shot Detector (SSD), Multi-layer Perceptron (MLP), or Attention Mechanism, but this It is not limited and various artificial neural network models can be applied to the present invention.

Even if heating is performed under the same conditions, the actual heating temperature of the individual room may be different depending on the geographic characteristics of individual households, such as drafts and the existence of upper and lower households, and as the geographic characteristics of these individual households are further learned, the output unit 76 ), the prediction accuracy of the information output from the current heating temperature of the private room is improved.

And, in the artificial neural network model, not only the data collected during test driving before moving in to the apartment house, but also the data collected after moving in can be continuously learned, and as the learning is continuously performed, the predictive model becomes more sophisticated, and the Prediction accuracy can be improved by reflecting unique characteristics well.

The query input unit 75 queries the learned model for the level of the first input temperature signal output from the first temperature sensor 30, and the output unit 76 determines the level of the queried first input temperature signal. According to the current heating temperature of the private room (that is, the level of the second input temperature signal) is output.

In another embodiment, in addition to the level of the signal of the first input temperature output from the first temperature sensing unit 30, data on the geographic characteristics of the corresponding household (direction, height, and location of individual households in one floor) are also included. It can be further queried, and since the computational model may be a model that has already learned the geographic characteristics of individual households, it predicts and outputs the heating temperature of the current private room reflecting the geographic characteristics as well.

In another example, the data learned in the learning module 74 is supplied to the heating line L through the return temperature, the flow rate of the return water flowing into the return unit 20 through the heating line L, and the distribution unit 10 . The temperature and flow rate of hot water, the time required from the time the heating temperature is set in the individual room temperature control unit 50 or the main temperature control unit 60 to the time when the current heating temperature of the individual room reaches the set heating temperature, It may be a data pair consisting of data consisting of the return water temperature and the heating temperature of the individual room accordingly. Further, in another embodiment, in addition to the above data pair, the direction of individual households (east, west, south, north, etc.), the height of individual households (lowest floor, middle floor, top floor, etc.), and the Multiple data pairs consisting of data pairs of positions (sidewall positions, intermediate positions, etc.) can be further learned, thereby improving prediction accuracy.

The data learned by the artificial neural network model may be a data pair collected during a test drive before moving into an apartment house, and unlike the embodiment in which only the water exchange temperature and the heating temperature of the individual room are learned, the accuracy of prediction as various data pairs are learned is improved In addition, the data collected after moving in can be continuously learned, and as the learning is continuously performed, the prediction model becomes more sophisticated, and the prediction accuracy can be improved by reflecting the unique characteristics of the corresponding generation.

The query input unit 75 queries the learned model for the level of the first input temperature signal output from the first temperature sensor 30, and the output unit 76 determines the level of the queried first input temperature signal. According to the current heating temperature of the private room (that is, the level of the second input temperature signal) is output. In addition, the query input unit 75 inquires about the current heating temperature of the private room and the heating temperature set in the main temperature control unit 60 to the model for which learning is completed, and the output unit 76 queries the current individual room according to the query. The time required until the heating temperature reaches the heating temperature set in the main temperature control unit 60 is output.

It can be further queried, and since the computational model may be a model that has already learned the geographic characteristics of individual households, it predicts and outputs the heating temperature of the current private room reflecting the geographic characteristics as well. In addition, the query input unit 75 queries the calculation model for the current heating temperature of the individual room and the heating temperature set in the main temperature control unit 60 , and the output unit 76 queries the current heating temperature of the individual room according to the query.

The lighting unit 80 is installed for each individual room, and is configured to provide light to the individual room. The lighting unit 80 may be turned on or off according to a user command input through the input units 55 and 65 of the individual room temperature control unit 50 or the main temperature control unit 60 , preferably the lighting unit 80 . It may be configured to sequentially change the intensity of .

How to control the heating system

With reference to FIG. 4 , the control method of the above-described heating system will be described in detail.

The heating temperature set in the individual room temperature control unit 50 and the second input temperature signal output from the second temperature sensing unit 40 provided in each individual room perform wireless communication from the individual room temperature control unit 50 . It is transmitted to the main temperature control unit 60 through the transmission, and the transmitted information is transmitted from the main temperature control unit 60 to the heating controller 70 through wired communication.

The heating controller 70 controls the heating system by controlling the opening/closing operation of the valve unit V so that the level of the transmitted second input temperature signal matches the heating temperature set in the individual room temperature control unit 50 .

Here, since the information transmitted to the heating controller 70 includes a unique individual room temperature control unit ID of each individual room temperature control unit 50 , a valve unit requiring opening/closing control among a plurality of valve units V It is possible to specify (V), and the opening and closing of the valve unit V is controlled so that the temperature of all individual rooms provided in each household matches the heating temperature set in each individual room temperature control unit 50 .

However, in the heating system control process, there may be a case in which a failure occurs in wireless communication between the individual room temperature control unit 50 and the main temperature control unit 60 .

In this case, it is impossible to transmit the level of the second input temperature signal output from the second temperature sensing unit 40 , that is, the current heating temperature of the individual room to the heating controller 70 .

Therefore, in the present invention, the control is performed by estimating the current temperature of the private room using the level of the first input temperature signal output from the first temperature sensing unit 30 , which is the return temperature.

That is, when a failure occurs in the wireless communication between the individual room temperature control unit 50 and the main temperature control unit 60 for more than a preset time, the heating controller 70 outputs the first The level of the input temperature signal is queried to the model that has been trained by the learning module 74 through the query input unit 75 . Since the first temperature sensing unit 30 is connected to the heating controller 70 by wire, it is possible to completely transmit the first input temperature signal to the heating controller 70 even if a wireless communication failure occurs. In response to the query of the query input unit 75 , the current heating temperature of the private room is output from the output unit 76 , and the heating control unit 73 sets the current heating temperature of the individual room output from the output unit 76 to the main temperature. The operation of the boiler 2 or the valve unit V is controlled to match the heating temperature of each individual room set in the control unit 60 . Accordingly, even if a wireless communication failure occurs, it is possible to control the heating of the private room by accurately predicting the current temperature of the private room using the temperature of the return water output from the first temperature sensing unit 30 .

In another example, the query input unit 75 receives the current heating temperature of the individual room output from the output unit 76 and the heating temperature of the individual room set in the main temperature control unit 60 after the learning of the learning module 74 is completed. The model can be queried, and accordingly, the time required until the current heating temperature of the individual room reaches the heating temperature of the individual room set in the main temperature control unit 60 is output from the output unit 76 . The heating control unit 73 controls the heating of the individual room by controlling the operation of the valve unit V according to the output required time.

On the other hand, when a failure occurs in wireless communication between the individual room temperature control unit 50 and the main temperature control unit 60, a communication failure message is displayed on the display 51 of the individual room temperature control unit 50, for example, " The message “Please proceed with setting the temperature of the individual room from the main temperature control unit or the wall pad” may be output. Accordingly, the user can set the heating temperature of each individual room through the main temperature control unit 60 , and since the main temperature control unit 60 communicates with the heating controller 70 by wire, the main temperature control unit 60 ), the heating temperature of each individual room may be completely transmitted to the heating controller 70 .

Thereafter, when the wireless communication between the individual room temperature control unit 50 and the main temperature control unit 60 is normalized, the heating controller 70 controls the main temperature control unit 60 from the individual room temperature control unit 50 . through the second input temperature signal and the heating temperature of each individual room set in the individual room temperature control unit 50 , so that the level of the second input temperature signal matches the heating temperature set in the individual room temperature control unit 50 . It controls the opening and closing operation of the boiler (2) or the valve part (V).

In addition, the heating controller 70 may control the heating temperature of each individual room according to a signal output from the Doppler sensor S configured to detect the presence of an object in an individual household or a movement of the object.

That is, in a state in which heating start is set in the main temperature control unit 60 or in a state in which the lighting unit 80 is turned on, there may be cases where a resident goes out, and performs heating control even when no one occupies an individual household, When the lighting unit 80 is turned on, unnecessary energy consumption may occur.

Therefore, when the presence or movement of an object of an individual household is not detected for more than a preset time by the Doppler sensor S, it is considered that there is no person occupant in the individual household, and the heating controller 70 controls the valve unit V By controlling the opening/closing operation, it is possible to control that heating is no longer performed.

In addition, when the presence or movement of an object of an individual household is not detected for more than a preset time, the main temperature control unit 60 controls the lighting unit 80 to turn off as there is no person occupant in the individual household. It is also possible to minimize consumption.

A method of controlling the lighting unit 80 may be performed by any one of a wired control method and a wireless control method.

In order for the lighting unit 80 to operate, power must be supplied to the lighting unit 80. In the case of a wired control method, the power supply line for supplying power to the lighting unit 80 may be configured to pass through the individual room temperature control unit 50. have. In the case of the embodiment to which the wired control method is applied, a separate battery may not be required for the individual room temperature control unit 50 (power may be supplied to the individual room temperature control unit through a power supply line).

In the case of the wireless control method, it can be used in the case of the embodiment in which the battery 54 is included in the individual room temperature control unit 50 , and in this case, a low-light solar cell is attached to the individual room temperature control unit 50 . Thus, the power produced by the solar cell may be supplied to the individual room temperature control unit 50 .

In the above, the present specification has been described with reference to the embodiments shown in the drawings so that those skilled in the art can easily understand and reproduce the present invention, but these are merely exemplary, and those skilled in the art can make various modifications and equivalents from the embodiments of the present application.
