The present invention relates to a gateway, a building automation system including the same, and an operation method thereof, and more particularly, to a gateway for controlling power saving operation at a peak time, a building automation system including the same, and an operation method thereof.

In order to produce a product in a factory or to manage various facilities in a building, a controller such as a programmable logic controller (PLC) or a direct digital controller (DDC) is required to control the facility. In addition, in order for each facility to operate normally, various sensors or actuators must be connected to the input / output device.

In the conventional automation system, the sensor installed in the field is transmitted to the central control computer in a point-to-point, and the control signal generated by the control computer is also transmitted to the actuator in a one-to-one manner. In case of large sized system and complicated system, many wires are connected for a long time, so it requires not only the cost of wiring but also a lot of effort and cost to maintain and repair the system when an error occurs. There was a problem that the entire system became inoperable.

Since the introduction of distributed control technology with the development of microprocessor technology, the centralized control function performed by the central computer is composed of a distributed system distributed to several small computers. Tied together as a device, they still had one-to-one connectivity with sensors and actuators installed in the field.

In order to improve this, the field bus, that is, the input / output device is deformed to be installed near the sensor or the actuator, that is, the input / output device is distributed in the field. Fieldbus dramatically simplifies wiring, handles large amounts of data that require rapid processing in process control and building control, and adds flexibility to field devices, providing flexibility in system configuration.

On the other hand, since the AC devices 3a, 3b, 3c, 4a, and 4b have a large amount of electric energy consumption, the electric charge and power consumption at a specific time become sensitive factors. In recent years, as energy consumption increases, more energy sources need to be developed and developed. In addition, the concept of the next-generation power grid, or Smart Grid, is designed to optimize energy efficiency by exchanging real-time information in both directions by integrating IT technology into the existing grid.

2 is a diagram illustrating a configuration of a gateway according to an embodiment of the present invention.

As shown in FIG. 2, the gateway 20 is connected to the first network N1 on one side and connected to the devices 32 and 33 and / or the second network N2 on the other side.

In this case, the first network N1 connected to the gateway 20 uses a first protocol that supports a communication method by binding network variables, and the gateway 20 connects to the first network N1. The devices 32 and 33 and / or the second network N2, which are connected to communicate with each other, use a second protocol different from the first protocol.

The connection between the gateway 20 and the devices 31, 32, 33 is one-to-one with the gateway 20, such as DX-Heat Reclaim Ventilation (DXHRV) 32 and Air-to-Water Heat Pump (AWHP) 33. It may be directly connected to, or via a second network (N2), such as the first and second indoor units (31a, 31b). In this case, the type and number of devices 32 and 33 that may be directly connected to the gateway 20 are not limited, and the connection topology and the number of nodes constituting the second network N2 are also limited. Of course not.

The devices 32, 33 and / or the second network N2 connected to the gateway 20 may each have a different set of network variables to communicate with the first network N1 separately, and thus the gateway 20 ) Stores the set of network variables for each of the devices 32, 33 and / or the second network N2 separately, and selectively changes and applies the set of network variables according to a signal communicating with the first network N1, The first network N1 and the devices 32 and 33 and / or the second network N2 may communicate by binding network variables.

In addition, the devices 32 and 33 and / or the second network N2 connected to the gateway 20 using the second protocol may use two or more different protocols. Thus, it is to be understood that the representation of the second protocol used herein is not intended to be limited to one protocol.

As shown in FIG. 2, the gateway 20 according to an exemplary embodiment of the present invention includes an NV (Network Variable) table 21 and a peak controller 22.

As described above, the NV table 21 is a network referenced for communication according to a communication method by binding network variables between the first network N1 and the devices 32 and 33 and / or the second network N2. Including a set of variables, the peak control section 22 determines the peak time zone, thereby setting or changing network variable values in the NV table 21 for the device 32, 33 and / or the second network N2. In addition, the devices 32 and 33 and / or the devices 31a and 31b connected to the second network N2 perform the power saving operation.

Meanwhile, the power information includes time zone and electricity rate information, and as shown in FIG. 3, the time zone may be divided into a normal time zone and a peak time zone in which an electric charge higher than the normal time zone is charged according to the electricity rate information. .

Electricity providers set high electricity rates based on real-time observed or statistical data for the time when the total power usage increases and the remaining power that can be supplied to each household is below a certain value. Indirectly regulates the use of electricity by imposing high electricity bills at times.

Such power information may be stored in advance in storage means (not shown) connected to the inside or outside of the gateway 20 or the building management system 10, or may be transmitted from a power supplier.

On the other hand, when the peak control section 22 determines the peak time zone, it is possible to directly determine whether the peak time zone based on the power information, or the peak variable of the NV table 21 reflecting the result determined by the other configuration. (nviPeak) may also be determined whether it is a peak time zone.

If it is determined that the peak control unit 22 corresponds to the current peak time zone, the devices 32 and 33 connected to the gateway 20 by changing network variable values such as nviOnOff, nviFanSpeedCmd, nviSpaceTemp, etc. of the NV table 21 and / or Alternatively, the controllers 31a and 31b connected to the second network N2 may operate to save power, thereby reducing power consumption.

At this time, the power saving operation is controlled by the gateway 20 to reduce the power consumption for the device (32, 33) and / or the device (31a, 31b) connected to the second network (N2) at a time so that the target power is set at the time of power saving. However, as shown in FIG. 3, it is preferable to reduce step by step according to time, current power consumption, or difference between the current power consumption and the target power consumption.

For example, when the device connected to the gateway 20 is an air conditioner, even in a peak time period, the user may perform a power saving operation by eliminating the discomfort of the user, which may be caused by stopping the cooling / heating at a time, and the peak time elapses. This is because the power consumption increase due to a sudden temperature change can be reduced even when switching to normal operation later.

Specifically, in order to reduce power consumption step by step, the indoor control temperature is controlled to increase or decrease the temperature every predetermined time, or the air flow is gradually lowered every predetermined time, or the cooling / heating operation is blown. It is possible to control such as switching to, but it is not limited to the air conditioner, it is a matter of course that can be appropriately controlled according to the characteristics of the device.

If there are a plurality of devices 32 and 33 connected to the gateway 20 and / or a plurality of devices 31a and 31b connected to the second network N2, the power saving operation may be performed individually or sequentially in a preset order. It is also possible to change and set the network variable value of the NV table 21.

As described above, the peak control unit 22 may determine whether the peak time is the peak time using a storage means (not shown) including the power information. It is desirable to determine whether or not. This is because by using the power information updated periodically or in real time, it is possible to have power information suitable for the current situation.

Accordingly, the gateway 20 according to an embodiment of the present invention may further include a first communication unit 23 and / or a first peak determination unit 24.

The first communication unit 23 is a means for receiving power information including electricity price information according to a time zone from the outside, and receives the power information periodically or in real time to the peak control unit 22 or the first peak determination unit 24. Can provide.

The peak control unit 22 may directly receive power information through the first communication unit 23 to determine whether the peak control time is the current peak time. Alternatively, the peak control unit 22 reflects the result of determining whether the peak control time is the current peak time. You may also refer to the values of certain network variables in 21).

That is, the first peak determination unit 24 receives the power information through the first communication unit 23, determines the peak time zone based on the received power information, and outputs the peak variable nviPeak of the NV table 21. ), The peak control unit 22 can indirectly determine whether the current peak time zone is indirect by reading the value of the peak variable, and if the gateway 20 does not include the first communication unit 23, By setting the peak variable value of the NV table 21 according to the data received through the first network N1, the peak control unit 22 may determine whether the current peak time zone is present by reading the peak variable value.

As described above, the gateway 20 according to an embodiment of the present invention may control the devices connected to the gateway 20 to perform power saving operation at peak times so as to enable efficient power consumption.

However, the peak control unit 22 according to the present embodiment reads the peak variable nviPeak value of the NV table 21 to recognize the peak time zone, and determines the peak time zone. Follow the data received through (N1).

Accordingly, the building management system 10 according to the present embodiment may include a second communication unit 11 and a second peak determination unit 12.

The second communication unit 11 is a means for receiving power information including electricity rate information according to a time zone from the outside, and receives the power information periodically or in real time and provides it to the second peak determination unit 12.

In this case, the second peak determination unit 12 determines whether the current peak time zone corresponds to the current peak time based on the power information received through the second communication unit 11, and the result is determined by the gateway (eg, through the first network N1). 20), the peak variable nviPeak value of the NV table 21 is set.

As a result, the peak control unit 22 of the gateway 20 may recognize the determination of the peak time zone by reading the value of the peak variable with reference to the NV table 21, and thus determine the peak time zone to the gateway 20 at the peak time zone. By changing the values of the NV table 21 corresponding to the connected devices 32 and 33 and / or the devices 31a and 31b connected to the second network N2, the corresponding device may be controlled to save power.
