The minimum personnel setting sections 300-1, ..., 300 based on the entry / exit signal received from the sensor detection unit, each of the compartment lighting server units has an algorithm that lights up when the number of the personnel signals is greater than the minimum number of persons, and turns off when the number is less. Referring to the drawings, an example in which a predetermined region A is divided into four zones is shown, but this is merely an example for explanation, and the present invention is not limited thereto. On the other hand, an illumination lamp corresponding to each of the m number of divisional areas is provided, and the illumination control server unit 200 is included in each of the divisional areas. At this time, at least one illumination light corresponding to one partition area may be provided, and further subdivision may be possible based on the minimum number of persons recorded in the internal database.

The illumination control server unit 200 transmits the entry signal to the illumination control server unit 200 based on the number of incoming and outgoing signals sent from the sensor unit, , ..., and 300-m, respectively. The minimum personnel setting unit 300 stores the sensor information (for example, the number of staff members, the sensor ID, the sensor location information), the illumination information (e.g., the illumination ID, the illumination position information, The number and arrangement information of the illumination lamps per division area, etc.), and the illumination lamp blinking control algorithm information, and the like. The minimum number setting unit 300 may include a minimum number setting unit 300 and a minimum number setting unit 300. The minimum number setting unit 300 may include a minimum number setting unit 300, As shown in FIG.

3, a detailed configuration of the sensor unit 100 constituting the illumination control system 1 according to the present invention will be described with reference to the above description. The sensor unit 100 senses a moving body entering or advancing into a predetermined area based on the moving direction of the moving body entering or leaving a predetermined area. The sensor unit 100 can detect the direction of a moving body entering or advancing into a predetermined area by detecting a moving body entering or exiting from a predetermined area. To this end, the sensor unit 100 includes a detection sensor 110. In addition, the initial setting control unit 130 is set according to the attachment position of the sensor. For example, the initial setting control unit 130 may have an initial setting value that allows entry and entry to be opposite to each other depending on the attachment position.

The sensor unit 100 further includes a sensor communication unit 120 that communicates with the illumination control server unit 200. The sensor communication unit 120 can perform communication with the illumination control server unit 200 through a wired communication method or a wireless communication method. The communication method performed by the sensor communication unit 120 may be any one selected from the group including Bluetooth, wifi, Modem, RFID, IrDA, UWB, But is not limited to these communication methods, and other possible communication methods not mentioned can be used. According to an embodiment of the present invention, it is preferable that the sensor unit 100 and the illumination control server unit 200 perform communication using an RF communication method. In this case, the sensor communication unit 120 may be an RF transmission / .

The RF wireless module sensor communication unit 120 further includes a sensor control unit. The sensor control unit controls the overall operation of the sensor unit 100.

In particular, when the movement of the human body is detected in the standby state (only the sensing sensor unit), the sensor control unit 110 operates the sensor communication unit to determine whether the sensor is entering or exiting from the sensor, To the lighting control server unit (200).

In particular, the sensor control unit 110 operates in a power down mode in which power down mode and wake-up mode are repeated to minimize power consumption when the transmission is completed.

Here, the power-down mode is a concept including a sleep state and a low-power state consuming minimum power. Specifically, the sensor control unit of the sensor unit 100 controls the detection sensor 110 and the sensor communication unit 120 to maintain the power down mode at normal times (when no human body detection signal is detected), and the detection sensor 110 A wake-up signal is issued to control the sensor control unit and the sensor communication unit 120 to switch to the wake-up mode. The sensor communication unit 120 can perform communication with the illumination control server unit 200 when in the wakeup mode. On the other hand, when the processing of the human body detection signal is completed, the sensor control unit can control the sensor communication unit 120 to switch to the power down mode again. Therefore, it is possible to operate the standby power consumption to be less than 2V 80uA by minimizing the consumed power. In this case, the AAA size battery can be operated for at least 2 years.

On the other hand, in configuring the illumination system of the present invention, the number of the sensor units 100 may be two or more. For example, a sensor unit 100 may be provided for each entrance and exit of a predetermined space having a plurality of outlets, and each sensor unit 100 may acquire a detection signal and transmit the detection signal to the illumination control server unit 200 have. In this case, it is preferable to set the detection sensor ID for each of the plurality of sensor units 100. When a plurality of sensor units 100 are installed and operated, the illumination control server unit 200 receives sensing signals (for example, incoming and outgoing signals) from the respective sensor units 100, It is possible to calculate the total number of staff members in the predetermined space by summing all the number of staff members received from the unit 100. [

The sensor unit 100 according to an embodiment of the present invention includes an infrared sensor. The infrared sensor includes a first sensing element, a second sensing element outputting a signal having a phase opposite to that of the first sensing element, and a second sensing element outputting a sensing signal SEN according to an output signal of the first sensing element and the second sensing element A body having a field effect transistor mounted therein, and an infrared cutoff portion surrounding the body and having a hollow portion extended downward from the body. Here, the length of the infrared ray blocking part can be adjusted according to the width of the infrared ray sensing area detected from the moving body. The infrared ray radiated from the moving body is not incident on the outside of the infrared ray blocking portion but the infrared ray radiated from the moving body is incident only through the hollow portion so that the directivity of the sensor can be enhanced. By using the infrared ray sensor having the high directivity as described above, it is possible to accurately determine whether or not the moving body enters or exits into the target space, and can accurately determine the number of moving bodies even if the moving body enters or advances into the target space have.

Next, referring to FIG. 4, a detailed configuration of the illumination control server unit 200 constituting the illumination control system 1 according to the present invention will be described.

As shown in the figure, the illumination control server unit 200 for controlling illumination includes a server communication unit 210 for receiving data from the sensor unit 100, a data processing unit 210 for processing data received through the server communication unit 210, A server control unit 230 for controlling the blinking of the illumination based on the information provided from the data processing unit 220, the information stored in the database unit 300, and a predetermined control algorithm, And a power supplier 250 for supplying power supplied from the outside according to a control signal to at least one or more illumination lamps. Here, the power providing unit 250 may be included as an internal configuration of the lighting control server unit 200 as shown in the figure, or may be separately configured separately from each other in the separate configuration.

Specifically, the server communication unit 210 is configured to perform communication with the sensor unit 100, and can communicate with the sensor unit 100 using a wire communication method or a wireless communication method as described above. For example, the server communication unit 210 may be implemented in any one or more ways selected from the group including Bluetooth, wifi, Modem, RFID, IrDA, UWB (Ultra Wideband), and Zigbee But not limited to, these communication schemes as well as other possible communication schemes not mentioned. According to an embodiment of the present invention, it is preferable that the sensor unit 100 and the illumination control server unit 200 perform communication using an RF communication method. In this case, the server communication unit 210 may be an RF transmission / .

The data processing unit 220 may process the data received from the sensor unit 100 by the server communication unit 210 and provide the processed data to the server control unit 230. For example, the data processing unit 220 may sum up the data received from the sensor unit 100 by the server communication unit 210 to grasp the room occupancy and control the power supply unit 250 to blink the lighting lamp. Further, as described above, when the illumination system 1 includes a plurality of sensor units 100, data transmitted from the plurality of sensor units 100 by the same ID can be summed and processed. For example, when a plurality of sensor units 100 are installed and operated, the illumination control server unit 200 receives incoming and outgoing signals sent from the respective sensor units 100, The total number of redundant rooms in the predetermined space can be calculated by summing all the signals of the same ID received from the mobile terminal.

In addition, through the user setting, the minimum personnel setting units 300-1, ..., and 300-m of FIG. 2 can be separately controlled by the illumination control server unit 200, It also includes functions. Therefore, the power supply unit 250 also includes a function of separately supplying power to two or more illumination lamps. For example, the minimum illumination power setting 300 is stored in the data processing unit 220, Can be separated and controlled again.

The server control unit 230 controls the overall operation of the illumination control server unit 200. Although not shown, the server control unit 230 may include a central control unit (CPU) that interprets a signal transmitted from the sensor unit 100 and issues a command to control blinking of the corresponding light according to a predetermined lighting control algorithm input by an administrator A central processing unit (CPU), a memory for storing data to be processed by a program, a program, and a control algorithm, and an input / output port for transmitting signals input and output by the server control unit 230.

In particular, the server control unit 230 controls the blinking of at least one or more illumination lights based on the information provided from the sensor unit 100 and the data processing unit 220 and the predetermined illumination control algorithm information stored in the database unit 300 . An exemplary illumination control algorithm is as follows. Specifically, when the illumination system according to the present invention provides dimming for a predetermined area partitioned into m zones, and m partition areas are respectively referred to as a first zone to an m zone, If the number of moving bodies counted by the incoming and outgoing signals received through the communication unit 210 is one or more, the lighting of the first zone can be controlled to be turned on. The server control unit 230 calculates an entry advance signal received through the server communication unit 210 through the minimum personnel setting unit set in the data processing unit 220 or the personnel setting unit dataized in the data processing unit 220, 220), the lighting unit is turned on in the power supply unit 250 if the number of redundant rooms is greater than the minimum number of persons in the power supply unit 250, and the lighting unit is turned off when the redundant number is less than the minimum number. In addition, the lighting control server unit 200 sets the minimum number of persons data set therein and judges whether it is turned on or off by comparing with the number of redundant rooms. If the data of the minimum number set in the inside or outside is set to the outside minimum (N1 &lt; N2 < N3, where N1, N2 and N3 are set to a predetermined value by user setting, An integer.)

In summary, the server control unit 230 compares the minimum personnel setting value with the minimum personnel setting value during internal minimum setting, and compares the minimum personnel setting value with the internally set personnel setting value during internal setting.

If the number of moving bodies received by the sensor unit 100 is equal to or greater than Nm-1, the server control unit 230 can control the illumination lamps in the m-th zone to additionally light up, in addition to the illumination lights in the first to m- (Where m is an integer of 2 or more and N1 < Nm-1 < Nm).

In the case where the illumination system according to the present invention includes a plurality of sensor units 100, the sensor control unit 230 compares the detection sensor ID with the illumination light ID set in the data processing unit 220, The power supply unit 250 supplies electric power only when the detection signal is received and the occupant count is calculated and compared with the set external minimum number or internal minimum number when it is greater than the set minimum number, Turn off the lights. When the normal communication is performed between the sensor unit 100 and the illumination control server unit 200, the signal transmitted from the sensor unit 100 to the illumination control server unit 200 is transmitted to the illumination control server unit 200 Transmits a response signal Ack to the sensor unit 100 and receives a response signal Ack for the signal transmitted from the sensor unit 100 to the illumination control server unit 200 due to a communication collision or the like The sensor communication unit 120 of the sensor unit 100 may transmit power to the sensor unit 100 in response to the power of the sensor unit 100. The sensor unit 100 may be configured to retransmit the transmission signal n times (for example, n = 3) Down mode and waits for the detection signal. If the sensor communication unit 120 of the sensor unit 100 does not receive the Ack signal, the sensor communication unit 120 waits for the retransmission in the standby state for a predetermined time and enters the power down mode after a predetermined time.

The power providing unit 250 performs switching ON / OFF for blinking of the corresponding illumination lamp according to the control signal received from the server control unit 230. [ Although not shown, the power supplier 250 may be configured to include a drive for driving a current required for flashing a light, and an FET (or a relay switch) for supplying or blocking electricity. For example, when a person enters a predetermined space in which the sensor unit 100 is installed, if the sensor unit 100 senses the presence of the user and transmits the detection result to the server communication unit 210, the central control unit of the server control unit 230 The lighting signal is transmitted to the electric power supplier 250 through the input / output port so that the drive of the electric power supplier 250 drives the FET (or relay switch) so that the lighting lamp in the zone area in the corresponding compartment or compartment is lighted. The power supply unit 250 may be controlled by the server control unit 230. The power supply unit 250 may be controlled by the server control unit 230, (For example, AC 220V) supplied from the outside in accordance with a signal. The power supply 250 may be a switched mode power supply (SMPS). The lighting control unit 200 may be provided with an illumination light ID for each of a plurality of illumination lights for switching. In addition, the LED lighting SMPS is always powered and can be kept in the standby state.

FIG. 5 shows an example in which a lighting system according to an embodiment of the present invention is applied to a predetermined space (for example, a library reading room). Referring to the drawings, in the present embodiment, a predetermined region provided with dimming by the illumination system according to the present invention is divided into four zone regions (A Zone, B Zone, C Zone, and D Zone) But the present invention is not limited thereto. Here, at least one illumination light providing dimming is provided for each of the divided areas. For example, four illumination lights 1b, 1d, 1f and 1h are provided in the A zone, four illumination lights 1a, 1c, 1e and 1g are provided in the B zone, two illumination lights 2a And 2b, and two illumination lights 2c and 2d may be provided in the D Zone. It is obvious that the number of the illumination lamps provided in each of the divisional areas can be set appropriately differently depending on the size of the divisional area, the position in which the divisional area is arranged in the predetermined space, etc., since this is only an example.

The minimum number of persons for the area partitioned by m as described above will be described. The first zone (A zone) is a basic illumination lamp. The server control unit 230 lights up according to an entrance signal sent by the sensor unit 100, and the server control unit 230 is turned off only when the occupancy is less than one person. Then, the lighting control server unit 200-2 having the minimum number of persons set in the second zone in the second zone lights up only when it is larger than the set minimum number of guests and turns off when it is smaller than the minimum number of guests. In the present embodiment, it is assumed that the minimum number of persons is set to A Zone = 1, B Zone = 49, C Zone = 77, and D Zone = 102. Therefore, when the number of occupants is less than 1, all the lights are turned off. In other words, A Zone <A minimum number, B Zone <B minimum number, C Zone <C minimum number, D Zone <D minimum number.

In addition, it also includes a function to control 1b, 1d, 1f, and 1h according to the personnel setting in the data set in the first zone (A Zone). At this time, it is desirable that the minimum outside personnel setting is set to be at least larger than a set maximum of the minimum inside staff of the first area. As described above, the server control unit 230 receives the entry signal and the advance signal received by the sensor unit 100 for the area divided by m, and when the external minimum number is set, the server control unit 230 compares the entry signal and the advance signal received by the sensor unit 100, Is turned on or off, and when the internal personnel is set, the lamp is turned on or off in comparison with the internal personnel setting. This can also be combined with the two functions described above. If the number of times of receiving the incoming and outgoing signals by the sensor unit 100 is Nm-1 or more, it is possible to additionally turn on the illumination lamps of the m-th zone in addition to the lighting of the first to m-1 zones , m is an integer greater than or equal to 2 and N1 < Nm-1 < Nm.) In this embodiment, m = 14, N1 = 49, N2 = 77, N3 = 102, .

If the number of occupants received by the sensor unit is zero, the lighting control server of each zone is smaller than the set number of personnel, so that all the lights are turned off. If the occupant is larger than the set minimum number Nm, The lights are turned on. Each of the m zones is turned on when the number of occupants is larger than the minimum number of occupants set by the illumination server unit, and turned off when the occupancy is less.

(Case 1), the entire illumination lamp is turned off. In case 2 (case 2), the illumination lights 1b and 1d corresponding to the first zone (A zone) 1f, and 1h). If there is an internal personnel setting, the staff numbers are compared with the internal personnel setting data, and the lamps 1b, 1d, 1f, and 1h are classified to control the lamps.

Next, in the case where the external minimum personnel set value is N1 or more (case 3), the illumination lamps 1a, 1c, 1e and 1g corresponding to the second zone B are additionally provided in addition to the illumination lamps corresponding to the first zone It lights up. Further, in the case where the occupant number is N2 or more (case 4), the illumination lamps 2a and 2b corresponding to the third zone (C Zone) are additionally turned on in addition to the illumination lamps corresponding to the first zone and the second zone. Finally, in the case where the occupant number is N3 or more (case 5), the illumination lamps 2c and 2d corresponding to the fourth zone (D zone) are additionally turned on in addition to lighting of the illumination lamps corresponding to the first to third zones . Conversely, when the number of occupants is less than N3, only the illumination lamps 2c and 2d corresponding to the fourth zone (D Zone) are extinguished, and when the number is less than N2, the illumination lamps 2a and 2b corresponding to the third zone (C zone) 1d, 1f, and 1g corresponding to the first zone (A zone) when the illumination lights 1a, 1c, 1e, and 1g corresponding to the second zone (B zone) 1h) is turned off, the entire system is turned off by sequential turn-off. Therefore, sequential illumination according to the number of people becomes possible. In addition, it is possible to control the lighting lamps according to each zone and to control each lamp separately from each other in detail.

When the above setting is made, the energy saving amount calculation result is shown in FIG. 6 according to the present invention (in the case of sequential lighting by zone). The numerical values in Fig. 6 are based on the reading room of a general university library, assuming that the consumed electric power per one illumination lamp is 80W, and that 40 or fewer persons occupy 16 hours per day in the reading room. As can be seen in the table, the annual power consumption when using the total illumination (prior art) is 28,032 kW, and the annual power consumption when using sequential lighting (the present invention) is 7,475 kW. Therefore, in this case, the power saving rate of the present invention is about 73.3% per year compared to the prior art. In other words, annual power consumption is only 26.6% of the conventional technology. As described above, according to the sequential automatic control lighting system using the count sensor according to the present invention, it is possible to accurately grasp the number of staff members in the target space, And can be individually turned on.
