Description

FIELD

The disclosure relates to illumination control and management technology in a building.

BACKGROUND

There have been technologies for automatically controlling lights in a building by sensing surrounding brightness through various sensors. Other automatic building illumination control facilities are installed and operated in such a manner that lights are turned on/off through central control according to a set relay for each lighting circuit group installed in each floor of a building and schedule control and pattern control are automatically performed according to a CCMS.

The inventors have noted that, in accordance with the current technologies, lights in a building are turned on/off according to previously set schedule irrespective of presence or absence of a user in the building, and thus the lights may be turned on in a vacant space, resulting in energy waste. Furthermore, since there are many lighting switches in the building, the inventors have noted that it is difficult for a user in the building to check switches in a corresponding area and to turn off unused lights when exiting from the building, causing further energy waste.

FIG. 3 is a flowchart of a method for automatically controlling illumination in a building in accordance with at least one embodiment.

Referring to FIG. 3, in the method for automatically controlling illumination in a building, the ID recognition unit 20 recognizes a user ID (or each user ID of a plurality of users) in step S11. The ID recognition unit 20 can recognize the user ID through a recognition means such as RF card recognition, fingerprint recognition, iris recognition and number recognition using a keypad.

Upon recognition of the user ID, the ID recognition unit 20 transmits information about the recognized user ID to the user access information collection unit 33 in step S13. The user access information collection unit 33 transmits the received information about the user ID to the access information management unit 32 in step S15.

Upon receipt of the information about the user ID, the access information management unit 32 checks the user ID in step S17. Here, the access information management unit 32 searches the user access DB 34 for data corresponding to the user ID and confirms (or analyzes and finally determines) an illumination data associated with the searched data.

The access information management unit 32 transmits the illumination list associated with the user ID to the building control unit 31 to request lighting control in step S19. The building control unit 31 delivers the received illumination list associated with the user ID to the main lighting control unit 35 in step S21.

The main lighting control unit 35 checks the received illumination list in step S23. Here, the main lighting control unit 35 can check (or search) the lighting circuit DB 36 to detect locations of lights associated with the user ID. Then, the main lighting control unit 35 requests lighting control to the mid-level lighting control unit 50 in order to control lights included in the illumination list in step S25. The mid-level lighting control unit 50, acting as switches, controls corresponding lights included in the illumination list to be turned on or off.

The mid-level lighting control unit 50 controls corresponding lights to be turned on or off according to the received lighting control signal at the lighting control request from the main lighting control unit 35 in step S27.

The building management server 30 can control illumination of a remote building. That is, the building management server 30 can control a remote building that is not equipped with an automatic illumination control system to control illumination in the remote building. Specifically, the building management server 30 may check whether a recognized user ID (or one or more recognized user IDs) corresponds to a user (or users) belonging to the remote building and control illumination of the remote building if the user ID corresponds to the user of the remote building. In this case, the building management server 30 checks whether the user enters the remote building, searches an illumination list in association with the user ID if the user enters the remote building, and transmits a signal for controlling all or some of the lights included in the searched illumination list to the mid-level lighting control unit 50 to turn all or some of the lights on or off. If the user corresponding to the checked user ID exits the remote building, the building management server 30 searches the illumination list in association with the user ID, checks (or determines) whether the illumination list includes at least one light included in another illumination list associated with another user. And if the illumination list includes the least one light included in the another illumination according to the determination, the building management server 30 transmits to the mid-level lighting control unit 50 a signal for controlling one or more remaining lights other than the at least one light included in the another illumination list associated with the another user to turn off.

In addition, the building management server 30 may calculate the number of people currently staying inside the building on the basis of user IDs to thereby check how may people is currently staying in the building, and store the calculated number at a memory or a storage equipped therewith or separately therefrom. Alternatively, the building management server 30 may check (or recognize and calculate) the number of people in the building by interworking with a so-called building heating ventilation and cooling system installed in the building. The number of people inside the building may be also used to check people existing in the building at the event of fire outbreaks or crime occurrence in the building.

Accordingly, all or some of lights in a building as well as remote buildings can be controlled to be tuned on/off by adaptively considering each recognized user ID of users entering to or exit from a building or a remote building regardless of whether or not people are inside a building, such that it is expected to reduce energy waste resulting from lighting of vacant space, to reduce the costs of changing lighting lamps, and to reduce the costs of energy for illumination. Furthermore, according to the various embodiments of this disclosure it can expect to get rid of the inconvenience of turning lights on/off using switches for a user and automatically turn lights on/off according to entry and exit information for people inside a building, thereby enhancing user convenience. In addition, it is possible to check how many people exist inside a building in real time, provide information about illumination energy consumption for each floor and each section of a building in real time to offer a power rate charging scheme in response to energy consumption, and thereby voluntarily reduce energy consumption in the building.

FIGS. 4 and 5 are flowcharts of a method for automatically controlling illumination in a building in accordance with at least one embodiment.

Referring to FIGS. 4 and 5, in the method of automatically controlling illumination in a building according to at least one embodiment, the building management server 30 is in a standby mode in step S31. Before being in the standby mode, the building management server 30 may check locations of offices (rooms, spaces, floors, sections and so on) in a building corresponding to a plurality of users staying in the building by detecting user IDs entering into or exit from the building, search a plurality of illumination lists associated with routes (or paths) through which the users move to or from the offices, match the searched illumination lists to user IDs and register the matched illumination list and user IDs.

The building management server 30 in the standby mode is configured to check (or detect) whether a specific user ID is recognized in step S33. Here, the building management server 30 can confirm (or analyze and/or determine) user information about the location(s) of an office(s) and a user name (or each user name) corresponding to the recognized user ID (or the recognized user IDs) in step S35. The building management server 30 recognizes the user ID (or each of the user IDs) through a recognition means such as RF card recognition, fingerprint recognition, iris recognition and number recognition using a keypad.

The building management server 30 detects whether the user (or each user) corresponding to the checked user ID (each of the checked user IDs) enters into or exit from the building in step S37. According to step S37, when the user enters into the building, the building management server 30 searches an illumination list (or each corresponding illumination list) associated with the recognized user ID (or each of the checked user IDs) in step S39. Then, the building management server 30 transmits a signal for controlling one or more lights included in the searched illumination list to the mid-level lighting control unit 50 to turn all or some of the lights on in step S41.

On the other hand, the user (or each user) corresponding to the user ID (each user ID) is detected to exit from the building in step S37, the building management server 30 searches then illumination list associated with the user ID (or each of the user IDs) in step S51. The building management server 30 checks (or determines) whether the searched illumination list includes at least one light included in another illumination list associated together with another user ID corresponding to another user who is currently in the building in step S53. If the illumination list includes the at least one light included in the another illumination list associated with the another user ID, the building management server 30 transmits a signal for controlling one or more remaining lights other than the at least one light included in the another illumination list associated together with the another user ID to the mid-level lighting control unit 50 to turn off in step S55. When the illumination list does not include the at least one light included in the another illumination list associated with the another user ID, the building management server 30 transmits to the mid-level lighting control unit 50 a signal for controlling all the lights (or some of the lights) included in the illumination list to turn off.

FIG. 6 is a flowchart of a method for automatically controlling illumination when a user moves in accordance with at least one embodiment.

Referring to FIG. 6, in the method for automatically controlling illumination when a user (or users) moves, the building management server 30 checks whether a user (or users) requests an illumination list while lights associated with a user ID of the user (or each user ID of the users) are turned on, in step S61. Alternatively, the user (each user of the users) may directly communicate with the building management server 30 through a web server for data transmission/reception in order to re-set (or register or establish) the illumination list according to the user's location change or user's route (or path). That is, the building management server 30 is configured to manage illumination lists even when many people in the building move simultaneously or sequentially, by allowing the user (each of the users) to directly re-set the illumination list associated with the user (or each user) itself.

When the user (or each of the users) requests the illumination list, the building management server 30 is configured to provide the screen for selecting a plurality of lights in step S63. The building management server 30 is configured to detect an input signal for selecting the illumination list requested by the user (or each of the users) in step S65. Then, the building management server 30 can receive and confirm (or analyze or determine) the illumination list input by the user (or each of the users).

The building management server 30 is configured to check (or determine or analyze) whether the number of lights included in the illumination list exceeds a predetermined number in step S67. If the number of lights included in the illumination list does not exceed the predetermined number, the building management server 30 sets the illumination list in step S69. The building management server 30 can turn on all or some of the lights corresponding to the set illumination list. That is, the building management server 30 may be configured to limit the authority to re-set the illumination list because the user (each of the users) directly sets the illumination list as much as needed when he moves. Accordingly, the building management server 30 is configured to control all or some of lights turned on in a wide range in the building.

If the number of lights included in the illumination list exceeds the predetermined number, the building management server 30 is configured to generate a warning message in step S71 and provide a screen for re-setting the illumination list. The warning message may represent that the number of lights included in the illumination list exceeds the predetermined number.

FIG. 7 a table of user information on entry into or exit from a building in accordance with at least one embodiment.

Referring to FIG. 7, user information stored in the user access DB 34 of the building management server 30 may include user IDs, locations of offices, illumination lists, and data corresponding to entry time and exit time. Each user ID may be updated for each entry into or exit from a building. For example, the illumination list is data about illumination necessary for a user (each of users) to move from an entrance of the building to his office and may be data for controlling lighting when the user (each of the users) enters into or exits from the building. Here, the user access DB 34 may is configured to store user information about occupants of the building. For example of user ID “1234” in FIG. 7, the user assigned as user ID 1234 is detected (or checked) in 5^th Floor section D by the management server 30. Illumination list of user ID 1234 as shown on the table of FIG. & includes at least one lights such as 1-G, 1-I, 5-I, 5-J, 5-K, and 5-D. Entry time (i.e., entrance time to enter into a building) of user ID 1234 indicates “2010. 08. 02 09:05.” Further, the user of user ID 1234 is detected to still stay in the building, because Exit time corresponding to user ID 1234 has not been detected and recorded on the table, yet. Accordingly, when he moves along his route in office location (e.g., 5^th Floor section D), all or some of lights associated with the illumination list of user ID 1234 may be controlled by the management server 30 to be turned all or some of the lights on/off.

FIG. 8 a view of a lighting circuit in accordance with at least one embodiment.

Referring to FIG. 8, locations of lights, stored in the lighting circuit DB 36 of the building management server 30 include data about an illumination list corresponding to each floor of the building. For example, if a user is now detected to be in the location of an office corresponding to section D 701 on the fifth floor of a building, the building management server 30 is configured to transmit a signal for controlling lights corresponding to 1-G and 1-I installed onto the way from an entrance gate to an elevator on the first floor, and 5-I, 5-J, 5-K and 5-D, which are installed from an elevator to the user's office (i.e., section D 701) to be turned on to the mid-level lighting control unit 50 to turn all or some of the lights on/off upon determining that the user enters the building by checking the user ID. Conversely, the building management server 30 is configured to control all or some of the lights corresponding to 1-G, 1-I, 5-1, 5-J, 5-K and 5-D to be entirely or partially turned off upon determining that the user exits the building by checking the user ID. In this case, the building management server 30 checks whether the illumination list corresponding to the user (or each of the users) includes at least one light associated with an illumination list of another user and, if the at least one light associated with the illumination list of the another user is not present, transmits a signal for controlling all the lights included in the illumination list corresponding to the user (or each of the users) to the mid-level lighting control unit 50 to turn the lights off. On the other hand, if the illumination list corresponding to the user (each of the users) includes the at least one light associated with the illumination list of the another user, the building management server 30 is configured to transmit a signal for controlling the rest of lights other than the at least one light associated with the another user to the mid-level lighting control unit 50 to entirely or partially turn the corresponding lights off.

In various embodiments as discussed above, all or some of lights can be entirely or partially tuned on/off regardless of whether or not people are inside a building, thereby reducing energy waste resulting from lighting of vacant space, reducing the costs of changing lighting lamps, and reducing the costs of energy for illumination.

Furthermore, various embodiments as discussed above can reduce the inconvenience subject to turning lights on/off using switches for a user and automatically turn lights on/off according to entry and exit information for people inside a building, thereby enhancing user convenience.

In addition, it is possible to detect or check the number of people inside a building in real time, provide information about illumination energy consumption for each floor and each section in real time to offer a power rate charging scheme in response to energy consumption, thereby inducing a user (each of users) in the building to voluntarily reduce energy consumption.
