The personal identification information 131 is information that uniquely identifies each of the plurality of employees 202 entering and leaving the office 200. Here, the employee number of the employee 202 is used as an example of the personal identification information 131. The personal occupancy information 132 is information indicating the occupancy status of each employee 202. Here, as an example of the personal occupancy information 132, flag data (hereinafter referred to as “resident occupancy”) that indicates that the value is true when the employee 202 enters the office 200 and the value is false when the employee 202 leaves the office 200. Flag)). The presence flag is stored in the storage device 130 in association with the employee number of each employee 202. The personal lighting information 133 includes at least one lighting fixture 201 that illuminates a work area (for example, a desk) of each employee 202 in the room to have a predetermined illuminance (for example, 750 lux) or more among the plurality of lighting fixtures 201. This is information associated with the employee 202. Here, as an example of the personal lighting information 133, the positional information of one or more lighting fixtures 201 that need to be lit to illuminate one employee 202 to illuminate the desk surface of the employee 202 at 750 lux or more. (Hereinafter, referred to as “illumination setting data”). The predetermined illuminance may be set for each employee 202. In other words, the lighting setting data indicates that one or more lights that need to be lit to illuminate another employee 202 to illuminate the desk surface of the employee 202 with an illuminance different from 750 lux (eg, 500 lux) or more. The position information of the instrument 201 can be indicated. A method for setting the illumination setting data by the setting PC 300 will be described later. Similar to the presence flag, the lighting setting data is also stored in the storage device 130 in association with the employee number of each employee 202.

  The control device 140 of the control unit 120 includes an entrance / exit management unit 141, an illumination specifying unit 142, and an illumination control unit 143.

  The control unit 120 can be mounted by a microcomputer (hereinafter referred to as “microcomputer”) or the like. The storage device 130 includes, for example, a flash memory built in a microcomputer, a random access memory, or the like. The control device 140 includes, for example, a central processing unit (hereinafter referred to as “CPU”) built in the microcomputer and a circuit connected to the microcomputer.

Can do.

  In FIG. 2, the card reader 110 reads a personal identification signal indicating the employee number of the employee 202 from the card 203 of the employee 202, and transmits the personal identification signal to the control device 140 of the control unit 120 (step). S101). That is, in step S101 (input step), the card reader 110 accepts input of personal identification information recorded on the card 203 of the employee 202, and transmits the personal identification information to the control device 140 of the control unit 120.

  The entrance / exit management unit 141 of the control device 140 receives the personal identification signal from the card reader 110 and confirms whether or not the employee number indicated by the personal identification signal is stored in the storage device 130 (step S102). If the employee number is not stored in the storage device 130 (NO in step S102), the entrance / exit management unit 141 does nothing or returns an error signal to the card reader 110. On the other hand, when the employee number indicated by the personal identification signal is stored in the storage device 130 (YES in step S102), the entrance / exit management unit 141 reads the corresponding occupancy flag from the storage device 130 (step S103). The value is confirmed (step S104). When the value of the occupancy flag indicates that the employee 202 has left the office 200, that is, is absent (NO in step S104), the entry / exit management unit 141 determines that the employee 202 has entered the room. (Step S105). When the value of the occupancy flag indicates that the employee 202 has entered the office 200, that is, is in the occupancy (YES in step S104), the entrance / exit management unit 141 leaves the employee 202. Is determined (step S106). In any case, the entrance / exit management unit 141 transmits an entrance / exit signal indicating the determination result to the illumination specifying unit 142 of the control device 140 and changes the value of the occupancy flag. The entrance / exit signal indicates the employee number indicated by the personal identification signal in addition to the determination result.

  As described above, in steps S102 to S106 (entrance / exit management step), the entrance / exit management unit 141 receives the personal identification information received by the card reader 110, and the personal identification information is stored in the storage device 130. The employee 202 is identified by collating with the personal identification information 131, and it is determined that the employee 202 has entered and exited the room. When the entry / exit management unit 141 identifies the employee 202, the entry / exit management unit 141 refers to the personal occupancy information 132 stored in the storage device 130 to determine whether the employee 202 has entered or exited, and the storage device 130. The personal occupancy information 132 stored in is updated.

  The illumination specifying unit 142 of the control device 140 receives the entrance / exit signal from the entrance / exit management unit 141 and reads the illumination setting data corresponding to the employee number indicated by the entrance / exit signal from the storage device 130. And the illumination specific | specification part 142 acquires the positional information on the lighting fixture 201 used in order to illuminate the desk of the employee 202 who entered or exited with 750 lux or more from the lighting setting data (step S107, S108). The illumination specifying unit 142 transmits an illumination position signal indicating the position information, and indicates an illumination position signal indicating command information for performing predetermined control (for example, blinking control) on the lighting fixture 201 to the illumination control unit 143 of the control device 140. Send to. When the entry / exit signal indicates that the employee 202 has entered the room, the instruction information indicated by the illumination position signal instructs, for example, to turn on the luminaire 201. On the other hand, when the entry / exit signal indicates that the employee 202 has left the room, the command information indicated by the lighting position signal instructs, for example, to turn off the lighting fixture 201.

  As described above, in steps S107 and S108 (illumination specifying step), the illumination specifying unit 142 is determined by the entrance / exit management unit 141 by referring to the personal lighting information 133 stored in the storage device 130. The lighting fixture 201 corresponding to the employee 202 is identified.

  The lighting control unit 143 of the control device 140 receives the lighting position signal from the lighting specifying unit 142 and performs predetermined control on the lighting fixture 201 based on the position information and the command information indicated by the lighting position signal. For example, if the command information instructs to turn on the lighting fixture 201, lighting control is performed on the lighting fixture 201 specified by the position information (step S109). For example, if the command information instructs to turn off the luminaire 201, the luminaire 201 specified by the position information is controlled to be turned off (step S110).

  Thus, in steps S109 and S110 (lighting control step), the lighting control unit 143 performs predetermined control on the lighting fixture 201 specified by the lighting specifying unit 142. When the entrance / exit management unit 141 determines that the employee 202 has entered the lighting control unit 143, the lighting control unit 143 turns on the lighting fixture 201 specified by the lighting specifying unit 142. On the other hand, when the entrance / exit management unit 141 determines that the employee 202 has left the room, the lighting control unit 143 turns off the lighting fixture 201 specified by the lighting specifying unit 142.

  According to the present embodiment, when the employee 202 enters the room, lighting control is automatically performed on a part of the plurality of lighting fixtures 201 that illuminate the room, and the work area of the employee 202 is set to an appropriate brightness. It becomes possible to adjust. Further, according to the present embodiment, when the employee 202 leaves the room, it is possible to automatically perform a turn-off control on the lighting fixture 201 that illuminates the work area of the employee 202.

  As described above, in the present embodiment, the lighting control system 100 reads a personal identification card (card 203) of an individual (employee 202) employed by an individual who uses the building or a company in the building. Positional relationship between a functional unit (entrance / exit management unit 141 of the control device 140) that is read by the (card reader 110) and manages exit / exit, and the luminaire 201 that affects each individual and the object (desk or document) in advance Between the function unit (illumination specifying unit 142 of the control device 140) that acquires information (personal lighting information 133) associated with the illuminating device 201 and the function unit (light control unit 143 of the control device 140) that controls the lighting fixture 201. By transmitting / receiving (entrance / exit signal, illumination position signal), the result of detection of the presence / absence of an individual is used for brightness control of the luminaire 201.

  According to the present embodiment, by receiving the absence signal, it is possible to turn off the luminaire 201 at the absentee position and reduce power consumption. Further, according to the present embodiment, malfunction does not easily occur because it does not depend on the human sensor. In addition, in the case where a human sensor is used, when a region corresponding to one human sensor is divided into two or more regions by a partition, it is necessary to install a human sensor in each region. According to the form, such a wiring replacement work at the time of changing the partition across the range of the human sensor is not required.

  Below, the setting method of the illumination setting data by setting PC300 (information processing apparatus) is demonstrated.

  First, the configuration of the setting PC 300 is shown in FIG.

  In FIG. 5, the setting PC 300 includes an illuminance calculation unit 301 and an information generation unit 302. The setting PC 300 includes hardware such as a recording medium 351, a CPU 352, an input device 353, an output device 354, and a communication device 355.

  The recording medium 351 is, for example, a flash memory or a magnetic disk of a magnetic disk device, and stores an operating system (hereinafter referred to as “OS”), a program group, and a file group. The program group includes programs that execute the functions of the illuminance calculation unit 301 and the information generation unit 302. The file group includes personal position data indicating the position of the work area of each employee 202 in the office 200, lighting position data indicating the position of each lighting fixture 201 in the office 200, and distribution indicating the light distribution characteristics of each lighting fixture 201. Includes optical data.

  For example, the CPU 352 operates an OS stored in the recording medium 351, reads a program group from the recording medium 351, and executes the program group.

  The input device 353 is, for example, a keyboard, a mouse, a touch panel, and a communication board, and accepts data input from a user for a program executed by the CPU 352.

  The output device 354 is, for example, a display device having a display screen of a CRT monitor or an LCD monitor, a printer device, and a communication board, and outputs a result of execution of a program by the CPU 352.

  The communication device 355 is, for example, a communication board, and is connected to the control unit 120 of the lighting control system 100 and transmits data to the control unit 120 or receives data from the control unit 120.

  Based on the personal position data, the illumination position data, and the light distribution data stored in the recording medium 351, the illuminance calculation unit 301 sets each of the illumination apparatuses 201 from the state where all the plurality of illumination apparatuses 201 in the office 200 are turned off. The CPU 352 calculates the illuminance of the work area of each employee 202 when the lights are turned on one by one in the order from the center of the work area of the employee 202.

  The information generation unit 302 sets the lighting setting that associates each employee 202 with the lighting device that is turned on when the illuminance calculated by the illuminance calculation unit 301 is equal to or greater than a predetermined illuminance (for example, 750 lux) as the personal illumination information 133. Data is generated by the CPU 352. Then, the information generation unit 302 transmits the illumination setting data to the control unit 120 of the illumination control system 100 through the communication device 355, and updates the illumination setting data stored in the storage device 130 of the control unit 120.

  Next, the operation of the setting PC 300 is shown in FIG.

  Here, it is assumed that the setting PC 300 automatically specifies the lighting fixture 201 necessary for each employee 202 from the seating chart shown in FIG. 7 and the lighting fixture arrangement plan shown in FIG. The seating chart corresponds to position data, and indicates the work area of each of the individuals A to F who are employees 202. Moreover, the said lighting fixture arrangement | positioning top view is equivalent to lighting position data and light distribution data, and shows the illumination distribution by each output light beam of each fixture 1-8 which is the lighting fixture 201, and each fixture 1-8. It is. In FIG. 8, the dashed ellipse indicates a region where the illuminance is 750 lux or more when only one of the appliances 1 to 8 is turned on. The shaded area indicates a region where the illuminance is 750 lux or more when only two of the appliances 5 and 6 are turned on.

  In FIG. 6, as an example, an operation of registering the lighting fixture 201 that is turned on in order to ensure an illuminance of 750 lux or more in Mr. E's work area is illustrated. The operation of registering the lighting fixture 201 that is lit to ensure the above illuminance is the same.

  In FIG. 6, the illuminance calculation unit 301 executes the following simulation processing by the CPU 352 (illuminance calculation step).

  The illuminance calculation unit 301 turns off the luminaires 1 to 8 in the office 200 in order to identify the luminaire 201 that secures Mr. E's work illuminance (step S151). Then, the illuminance calculation unit 301 turns on the fixture 6 that is the lighting fixture 201 located closest to the center of Mr. E's work area (step S152), and the lowest illuminance of Mr. E's work area becomes 750 lux or more. It is determined whether or not (step S153). As shown in FIG. 8, in the state where only the appliance 6 is lit, the minimum illuminance is less than 750 lux in a part of Mr. E's work area (NO in step S153). The lighting device 7 that is the lighting device closest to the center of Mr. E's work area is turned on (step S152), and it is determined again whether the minimum illuminance of Mr. E's work area is 750 lux or more (step S152). Step S153). As shown in FIG. 8, in the state where the appliance 6 and the appliance 7 are turned on, the minimum illuminance is 750 lux or more in the entire work area of Mr. E (YES in step S153). 6 and 7 can be specified as the lighting fixture 201 that secures Mr. E's working illuminance. Thereby, the simulation process of the illumination intensity calculation part 301 is complete | finished.

  As described above, when the appliance 6 and the appliance 7 are specified by the simulation processing of the illuminance calculation unit 301, the information generation unit 302 illuminates the appliance 6 and the appliance 7 as the illumination fixture 201 that secures Mr. E's working illuminance. Registration in the setting data (step S154: information generation step).

  Steps S151 to 153 in FIG. 6 are not simulation processing, and can be performed by actually turning on or off the lighting fixture 201 by a human or an automatic control device. Moreover, when there is no light distribution data of each lighting fixture 201, you may implement, measuring the illumination intensity when actually lighting the lighting fixture 201 with an illumination sensor.

  In step S153 in FIG. 6, when the illuminance calculation unit 301 determines that the minimum illuminance exceeds 750 lux, which is the set illuminance, in the entire work area of Mr. E, the information generation unit 302 performs the instrument 6 and / or the instrument 7. A setting of dimming to maintain 750 lux may be registered in the illumination setting data. When this illumination setting data is used, the illumination specifying unit 142 of the control device 140 provides the illumination control unit 143 with an illumination position signal indicating command information for instructing to perform dimming control as predetermined control for the lighting fixture 201. Will be sent.

  Before step S151 in FIG. 6, the setting PC 300 displays the seating chart and the lighting equipment arrangement plan on the screen of the display device so that each employee 202 can refer to the seating chart and the lighting equipment arrangement plan in advance. Also good. Then, each employee 202 may select and register the lighting fixture 201 that the employee 202 wants to use by manual operation. In this case, the information generation unit 302 of the setting PC 300 receives a designation input of the lighting fixture 201 from the employee 202 with a mouse or a touch panel. Then, the information generation unit 302 of the setting PC 300 registers the lighting fixture 201 related to the designated input in the lighting setting data as the working lighting fixture 201 of the employee 202.
