Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an energy management system using a room sensor according to an embodiment of the present invention.

Referring to FIG. 1, an energy management system 100 (hereinafter, referred to as an 'energy management system') using a room sensor according to an embodiment of the present invention includes a room sensor 110, an on / ), A repeater 130, and a server 140. [

The energy management system 100 can detect the presence of a person using the room sensor 110 and remotely operate the lighting equipment 200 and the heating and cooling equipment 300 using the relay 130. In addition, the server 140 collects data of the occupant detection sensor 110 through the repeater 130 and monitors the amount of power and the like according to the operation of the on / off controller 120, thereby enabling efficient energy management.

By providing a plurality of occupant detection sensors 110 in parallel in one space, it is possible to increase the probability of occupant detection and reduce the malfunction rate of the energy management. In addition, the server 140 can remotely monitor whether or not the occupant detection sensor 110 is operating normally, so that errors in the occupant detection sensor 110 can be easily identified.

In particular, energy efficiency can be improved by varying the control of the lighting equipment 200 or the heating / cooling equipment 300 according to night or nighttime.

The occupant detection sensor 110 and the on / off controller 120 are configured to receive the power of the server 140 rather than the commercial power in the building through the repeater 130 and the RS485 cable, And the on / off controller 120 in the building. And facilities for supplying commercial power can be reduced.

Hereinafter, the detailed configuration will be described.

A plurality of the occupancy detection sensors 110 may be provided, and they may be connected to each other in parallel to detect whether there is a person in the room. For example, when three occupant detection sensors 110 are dispersed in various places in one office, it is possible to more accurately detect whether or not there is a person. At this time, if only one of the occupant detection sensors 110 detects the occupant detection sensor 110, it can be determined that there is a person.

The occupant detection sensor 110 can be configured to detect various methods such as motion detection and infrared detection.

The occupant detection sensor 110 may further include an LED indicator (not shown) indicating whether the occupant detection sensor 110 operates normally. The user can visually confirm whether the LED indicator is on so that the user can immediately check which room sensor 110 is in trouble. At this time, it is preferable that the LED indicator is turned on or off through the pre-installed ammeter and the detected value is provided to the server 140. That is, the server 140 can determine whether the occupant detection sensor 110 has failed according to the detection value. It is impossible for a user to individually detect whether a large number of occupant detection sensors 110 fail in a large building. Accordingly, it is preferable that the server 140 can be visually confirmed through the LED indicator and that the normal operation or the normal operation is provided to the server 140 so that the server 140 can recognize the operation. The occupant detection sensor 110 may be provided with a predetermined ID, and it is preferable that the ID of the failed occupant detection sensor 110 is informed to the smart terminal of the user.

The on / off controller 120 turns on the lighting equipment 200 or the heating / cooling equipment 300 when detecting that there is a person in at least one of the plurality of the room detection sensors 110 . This is possible because the occupant detection sensors 110 are connected in parallel with each other.

The on / off controller 120 may be configured to turn off the lighting fixture 200 or the heating / cooling facility 300 when the plurality of occupant detection sensors 110 detect that the person is not present.

The on / off controller 120 may be operated by such an automatic mode, but may be configured to be operated in a manual mode in which a person directly switches on / off. The server 140 can also be configured to remotely control the conversion of the automatic mode / manual mode.

Meanwhile, the on / off controller 120 transmits the sensing value of the room sensor 110 and the on / off values of the lighting equipment 200 and the heating / cooling equipment 300 to the server 140 via the repeater 130 Lt; / RTI > These sensing values and on / off values are used for remote control and power monitoring.

The relay 130 may be configured to receive the sensing value and the on / off value from the on / off controller 120 via the RS485 communication cable and transmit it to the server 140. In the case of a large building, a number of occupancy detection sensors 110 may be connected to the repeater 130 and relayed to the server 140. The repeater 130 may relay to the server 140 provided in the external network. At this time, the server 140 is preferably a dedicated energy management server configured to manage a plurality of buildings or business facilities in an integrated manner.

Meanwhile, the repeater 130 may be configured to supply power from the server 140 to the on / off controller 120 and the room sensor 110 through an RS485 cable. In this case, since the on / off controller 120 and the occupant detection sensor 110 do not need to use the commercial power provided in the building, it is advantageous to install the on / off controller 120 in the building.

The server 140 receives the sensing value and the ON / OFF value from the relay 130 via the RS485 communication cable and monitors the operation status of the room sensor 110, the lighting equipment 200, and the heating / . At this time, the on / off value can be used to calculate the actual amount of power of the lighting equipment 200 or the heating / cooling equipment 300.

The server 140 may be configured to remotely control the occupant detection sensor 110 and the on / off controller 120. In the automatic mode, the on / off controller 120 may be configured to automatically control the operation of the on / off controller 110 according to the sensed value of the occupant detection sensor 110. In the manual mode, The on / off controller 120 may be configured to operate according to the switch.

The server 140 controls the on / off controller 120 to operate in an auto mode in which the on / off controller 120 operates in conjunction with the room sensor 110 during a day, 6), the on / off controller 120 may be controlled to operate in a manual mode operated by manual control of the user. In other words, it operates in the automatic mode during the week in which many people move or move, and operates only in the passive mode at the late night or at the sleep time when there is no person.

The server 140 may be configured to automatically calculate the power consumption of the lighting equipment 200 and the heating / cooling equipment 300 according to the operation control of the on / off controller 120. Therefore, it is possible to calculate and utilize the trends of power consumption per hour, day, month, year, and season. The server 140 may estimate the power demand by time, day, month, year, and season, and may request the user's smart terminal to wait for the standby power. In particular, it is desirable to calculate the power demand by calculating the trend of the power consumption in the building by temperature / humidity and obtaining the statistics.

Meanwhile, the server 140 may be configured to receive a signal indicating whether the corresponding LED indicator (not shown) is turned on from the occupant sensor 110 to determine whether the occupant sensor 110 is normal or malfunctioned. That is, although the user can visually check whether the LED indicator is turned on, the LED indicator may further include an ammeter to receive the current value of the occupant sensor 110 from the server 140, It is possible to judge whether or not it is normal operation.

2 is a flowchart illustrating an energy management method using a room sensor according to an embodiment of the present invention.

Referring to FIG. 2, a plurality of occupant detection sensors 110 connected in parallel to each other detects whether there is a person in the room (S101).
