Description

  The present invention relates to a control system, a control method, and a control program.

  In recent years, a control system that comfortably controls a space such as an office by controlling lighting or the like is becoming widespread. For example, in such a control system, an optical sensor is attached to the ceiling. In a control system in which an optical sensor is attached to the ceiling, control is performed based on the illuminance measured on the ceiling, so there may be cases where the illuminance is not comfortable on a desk or the like where work is actually performed. Also, in such a control system, control is performed based on the layout of a desk or the like when the lighting device or the optical sensor is designed, so that there may be a case where the illuminance is not comfortable in the environment after the layout is changed. For this reason, it is desired that such a control system controls the illuminance so that the place where work is actually performed becomes a comfortable space.

[Composition of comfortable space control system]
First, the configuration of the comfortable space control system according to the first embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating a configuration example of a comfortable space control system 1 according to the first embodiment. The comfortable space control system 1 is a system that realizes control and monitoring of a lighting device or the like installed in an office or home. For example, the comfortable space control system 1 acquires information on the environment in which the lighting device is installed using a sensor or the like, and controls the lighting device based on the acquired information. In the example of FIG. 1, the comfortable space control system 1 controls the brightness in the office Rm in which the desks De1 to De12 are arranged.

  As shown in FIG. 1, the comfortable space control system 1 includes lighting devices 10A to 10L, optical sensors 100A to 100L, and a control device 200. Hereinafter, when it is not necessary to distinguish the lighting devices 10A to 10L, these may be collectively referred to as “lighting device 10”. In addition, when it is not necessary to distinguish between the optical sensors 100A to 100L, these may be collectively referred to as “optical sensor 100”.

  Lighting devices 10A to 10L, optical sensors 100A to 100L, and control device 200 communicate via a network. As an aspect of the network, there is a communication network such as a LAN (Local Area Network) regardless of wired or wireless.

For example, the control device 200 outputs a control signal for controlling the illuminance of light emitted from the illumination device 10 to the illumination device 10 based on the illuminance measured by the optical sensor 100 and the position of the optical sensor 100. In the example of FIG. 1, the optical sensor 100A is installed in the irradiation direction of light emitted from the lighting device 10A and is closer to the lighting device 10A than other lighting devices. For this reason, as an example, the control device 200 controls the illuminance of light emitted by the illumination device 10A based on the illuminance measured by the optical sensor 100A.

  Thus, in the comfortable space control system 1, the control device 200 controls the illuminance of light emitted from the lighting device 10 based on the illuminance information received from the optical sensor 100 and the position of the optical sensor 100. The illumination can be controlled to be comfortable for the user.

  The measurement unit 121 measures various information on the space controlled by the comfortable space control system 1. Specifically, the measurement unit 121 measures the illuminance of light emitted from the lighting device 10. Moreover, the measurement part 121 measures illuminances, such as external light which enters from the window installed in the space which the comfortable space control system 1 controls.

  The transmission / reception unit 131 transmits various information on the space controlled by the comfortable space control system 1 in accordance with instructions from the control device 200.

For example, the illumination information storage unit 221 stores information related to the illuminance of light emitted from the illumination device 10 and the position where the illumination device 10 is installed in association with the illumination ID of the illumination device 10. Here, FIG. 4 illustrates an example of the illumination information storage unit 221 of the control device 200 according to the first embodiment. As illustrated in FIG. 4, the illumination information storage unit 221 includes items such as “illumination ID”, “position”, and “illuminance”.

  “Lighting ID” indicates a unique identifier for identifying the lighting device 10 installed in the space controlled by the comfortable space control system 1. “Position” indicates a position where the lighting device 10 is installed. For example, in the “position”, an X coordinate and a Y coordinate indicating a position where the lighting device 10 is installed in the space controlled by the comfortable space control system 1 are stored. The “position” may store a Z coordinate indicating the height at which the illumination device 10 is installed. “Illuminance” indicates illuminance, which is an index of the intensity of light emitted from the lighting device 10.

  That is, FIG. 4 shows an example in which the illumination device 10 with the illumination ID “L1” is installed at the position of coordinates (X1, Y1). In addition, the illumination device 10 with the illumination ID “L1” shows an example in which light with an illuminance “500 (lux)” is emitted.

  The sensor information storage unit 222 stores information related to the optical sensor 100 installed in the space controlled by the comfortable space control system 1. For example, the sensor information storage unit 222 stores illuminance information indicating the position where the optical sensor 100 is installed and the illuminance measured by the optical sensor 100 in association with the sensor ID that identifies the optical sensor 100. Here, FIG. 5 illustrates an example of the sensor information storage unit 222 of the control device 200 according to the first embodiment.

  “Sensor ID” indicates a unique identifier for identifying the optical sensor 100 installed in the space controlled by the comfortable space control system 1. “Position” indicates a position where the optical sensor 100 is installed. For example, in the “position”, an X coordinate and a Y coordinate indicating the position where the optical sensor 100 is installed in the space controlled by the comfortable space control system 1 are stored. The “position” may store a Z coordinate indicating the height at which the optical sensor 100 is installed. “Illuminance” indicates the illuminance measured by the optical sensor 100.

  That is, FIG. 5 shows an example in which the optical sensor 100 with the sensor ID “Se1” is installed at the position of coordinates (x1, y1). The optical sensor 100 with the sensor ID “Se1” shows an example in which light with an illuminance “400” is measured.

  Returning to FIG. 3, the control unit 230 is a device that controls the control device 200. As the control unit 230, an electronic circuit such as a CPU (Central Processing Unit) and an MPU (Micro Processing Unit), or an integrated circuit such as an ASIC (Application Specific Integrated Circuit) and an FPGA (Field Programmable Gate Array) can be employed. The control unit 230 has an internal memory for storing programs defining various processing procedures and control data, and executes various processes using these. The control unit 230 functions as various processing units when various programs operate. For example, the control unit 230 includes a reception unit 231, a specification unit 232, an environment control unit 233, a storage unit 234, and a transmission / reception unit 235.

  The receiving unit 231 receives various information related to the space controlled by the comfortable space control system 1. Specifically, the receiving unit 231 receives illuminance information transmitted by the transmitting / receiving unit 131 of the optical sensor 100. For example, the receiving unit 231 receives illuminance information from the optical sensor 100 by wireless communication.

  The specifying unit 232 specifies the position of the optical sensor 100. Specifically, the specifying unit 232 specifies the position of the optical sensor 100 based on the illuminance measured by the measuring unit 121 of the optical sensor 100 with one of the lighting devices 10 sequentially turned on. To do. For example, the specifying process for specifying the position of the optical sensor 100 by the specifying unit 232 receives a time when there is no outside light such as nighttime and there is no office worker, or a position detection instruction in an initial value setting mode for setting the position of the optical sensor 100. It is executed when

  This point will be described in detail with reference to FIGS. 6-9 is explanatory drawing for demonstrating the specific process by the control apparatus 200 which concerns on 1st Embodiment. As shown in FIGS. 6 to 9, the control device 200 uses one lighting device among a plurality of lighting devices installed in an office Rm that is a space controlled by the comfortable space control system 1, for example, another light source such as nighttime. It is controlled so that it lights up sequentially in the absence of light. In addition, as shown in FIG. 6, it is preferable that the several optical sensor 100 is installed previously so that it may not overlap in the same office Rm.

  In the example of FIG. 6, the control device 200 controls the lighting device 10A to turn on among the plurality of lighting devices 10A to 10L installed in the office Rm via the cable Ca. Here, it is assumed that the illumination device 10A emits light whose light distribution curves are curves L1a to L1d, as shown in FIG. The light distribution curve is a curve that schematically represents the direction and intensity of light. For example, the light distribution curve indicates that the illuminance of light is lower as the distance from the light source is longer. For this reason, in the example of FIG. 1, the position of the curve L1a indicates that the illuminance is higher than the position of the curve L1d. It is assumed that the light distribution curve is known in advance for each illumination device and stored in the illumination information storage unit 221 of the storage unit 221. And the control apparatus 200 requests | requires illumination intensity information first with respect to 100 A of optical sensors. Then, the optical sensor 100A transmits illuminance information indicating the measured illuminance to the control device 200. Thereby, the control device 200 stores the illuminance indicated by the illuminance information received from the optical sensor 100A in the sensor information storage unit 222 in association with the sensor ID of the optical sensor 100A. Similarly, the control device 200 requests the illuminance information from the optical sensors 100B to 100L, and associates the illuminance indicated by the received illuminance information with the sensor IDs of the sensors 100B to 100L in the sensor information storage unit 222. Store. Then, the specifying unit 232 determines that the optical sensor 100A is installed between the curve L1a and the curve L1b based on the illuminance measured by the optical sensor 100A.

  Subsequently, as illustrated in FIG. 7, the control device 200 controls the lighting device 10 </ b> A to be turned off and the lighting device 10 </ b> B to be turned on via the cable Ca. Here, it is assumed that the illumination device 10B emits light whose light distribution curves are curved lines L2a to L2d as shown in FIG. The control device 200 sequentially requests illuminance information from the optical sensors 100A to 100L, and associates the illuminance indicated by the received illuminance information with the sensor IDs of the optical sensors 100A to 100L. To store. Thereafter, the specifying unit 232 determines that the optical sensor 100A is installed between the curve L2c and the curve L2d based on the illuminance measured by the optical sensor 100A.

  Thereafter, as illustrated in FIG. 8, the control device 200 controls the lighting device 10 </ b> B to be turned off and the lighting device 10 </ b> C to be turned on via the cable Ca. Here, it is assumed that the illumination device 10C emits light whose light distribution curves are curved lines L3a to L3d, as shown in FIG. The control device 200 sequentially requests illuminance information from the optical sensors 100A to 100L, and associates the illuminance indicated by the received illuminance information with the sensor IDs of the optical sensors 100A to 100L. To store. Thereafter, the specifying unit 232 determines that the optical sensor 100A is installed between the curve L3c and the curve L3d based on the illuminance measured by 100A.

  Then, as illustrated in FIG. 9, the specifying unit 232 determines that the position of the optical sensor 100A is between the curves L1a and L1b, between the curves L2c and L2d, and between the curves L3c and L3d. Identify. Similarly, the specifying unit 232 specifies the positions of the other optical sensors 100B to 100L for each optical sensor. As an example, the specifying unit 232 specifies the position of the optical sensor 100B as being between the curves L1b and L1c, between the curves L2b and L2c, and between the outside of the curve L3d.

  Returning to FIG. 3, the environment control unit 233 controls the environment of the space controlled by the comfortable space control system 1. Specifically, the environment control unit 233 controls the illuminance of light emitted from the lighting device 10 based on the illuminance received by the receiving unit 231 and the position of the optical sensor 100. For example, the environment control unit 233 controls the illuminance of light emitted from the lighting device 10 based on the illuminance information received by the receiving unit 231 and the position of the optical sensor 100 specified by the specifying unit 232. As an example, the environment control unit 233 acquires the illuminance and position measured by the optical sensor 100 from the sensor information storage unit 222, and acquires the illuminance and position of the lighting device 10 from the illumination information storage unit 221. A control signal for controlling the illuminance of the light emitted from the lighting device 10 is generated based on the information on the illuminance and the position. In the example of FIG. 1, the optical sensor 100A is installed in the irradiation direction of light emitted from the lighting device 10A, and is closer to the lighting device 10A than other lighting devices. For this reason, the environment control part 233 controls the illumination intensity of the light which 10 A of illuminating devices emit based on the illumination intensity measured by the optical sensor 100A. Thereby, the environment control part 233 can control to illumination intensity comfortable for the office worker of desk De1.

  In another example, the environment control unit 233 controls the illuminance of light emitted from the lighting device 10 so that the illuminance in the space controlled by the comfortable space control system 1 is uniform. In the example of FIG. 5, since the illuminance is “400” at the position (x1, y1) where the optical sensor 100 with the sensor ID “Se1” is installed, the optical sensor 100 with the sensor ID “Se2” with the illuminance “500”. Is darker than the position (x2, y2) where is installed. For this reason, the environment control unit 233 controls the illuminance of the light at (x1, y1) to be “500” by increasing the light emitted by the illumination device 10 located near (x1, y1). Further, in the example of FIG. 5, since the illuminance is “600” at the position (x3, y3) where the optical sensor 100 with the sensor ID “Se3” is installed, the light with the sensor ID “Se2” with the illuminance “500”. Brighter than the position (x2, y2) where the sensor 100 is installed. For this reason, the environment control unit 233 controls the illuminance of the light at (x3, y3) to be “500” by weakening the light emitted by the illumination device 10 located near (x3, y3). As a result, the environment control unit 233 can control the lighting to a predetermined brightness even in a dark seat away from the lighting device 10, for example, and can provide a comfortable environment for the office worker regardless of location. . Moreover, since the environment control part 233 can control illumination weakly in the bright seat where external light enters from a window, it can suppress a utility bill.

  The storage unit 234 stores various types of information related to the space controlled by the comfortable space control system 1 in the storage unit 220. Specifically, the storage unit 234 stores the illuminance information received by the receiving unit 231 in the sensor information storage unit 222 in association with the sensor ID of the optical sensor 100. Further, the storage unit 234 stores the coordinates indicating the position of the optical sensor 100 specified by the specifying unit 232 in the sensor information storage unit 222 in association with the sensor ID of the optical sensor 100. The storage unit 234 stores the illuminance indicated by the control signal generated by the environment control unit 233 in the illumination information storage unit 221 in association with the illumination ID that identifies the illumination device 10.

  The transmission / reception unit 235 transmits the control signal generated by the environment control unit 233 to the lighting device 10. For example, every time a control signal is generated by the environment control unit 233, the transmission / reception unit 235 transmits the control signal to the lighting device 10 by wired communication via a cable.

[Processing procedure of comfortable space control system]
Next, the flow of control processing by the comfortable space control system 1 according to the first embodiment will be described with reference to FIG. FIG. 10 is a sequence diagram illustrating a processing procedure performed by the comfortable space control system according to the first embodiment.

  In the example of FIG. 10, the comfortable space control system 1 starts the control process when, for example, a preset time, a predetermined interval, or the lighting device 10 is turned on.

  Specifically, first, the illumination device 10 turns on the illumination (step S101). For example, the lighting device 10 is turned on when a predetermined time is reached, turned on when a person is detected, or an operator operates a switch installed on a wall or the like to turn on the lighting. For example, a method of turning on the illumination when turned “ON” can be adopted.

  Thereafter, the optical sensor 100 measures the illuminance of the light emitted from the illumination device 10 (step S102). Here, it is assumed that the optical sensor 100 is installed around a fixture in the irradiation direction of light emitted from the lighting device 10, for example. For this reason, the optical sensor 100 measures the illuminance of light around the installed fixture.

  And the optical sensor 100 transmits the illumination intensity information which shows the measured illumination intensity to the control apparatus 200 (step S103). For example, the optical sensor 100 transmits illuminance information to the control device 200 by wireless communication. Thereby, the control apparatus 200 receives the illuminance information transmitted by the optical sensor 100 from the optical sensor 100.

  Subsequently, the control device 200 stores the received illuminance information in the sensor information storage unit 222 in association with the sensor ID of the optical sensor 100 (step S104). For example, every time the illuminance information is received from the optical sensor 100, the control device 200 stores the illuminance in the sensor information storage unit 222 in association with the sensor ID.

  Thereafter, the control device 200 controls the illuminance of light emitted from the illumination device 10 based on the received illuminance information and the position of the optical sensor 100 (step S105). For example, the control device 200 generates a control signal for controlling the illuminance of light emitted from the illumination device 10 based on the illuminance stored in the sensor information storage unit 222 and the position of the optical sensor 100 and transmits the control signal to the illumination device 10. To do. Note that the position of the optical sensor 100 is specified based on, for example, the illuminance measured by the optical sensor 100 in a state where one of the plurality of lighting devices 10 is sequentially turned on.

  Thereby, the lighting device 10 receives the control signal from the control device 200. And the illuminating device 10 lights illumination with the illumination intensity based on the received control signal (step S106). In addition, the control device 200 stores the illuminance indicated by the generated control signal in the illumination information storage unit 221 in association with the illumination ID of the illumination device 10.

[Effect of the first embodiment]

Thereby, since the control apparatus 200 can manage the health condition of the worker, it is possible to detect a poor physical condition at an early stage and provide a safe working environment that does not make the worker unreasonable.

  In another example, the measurement unit 121 captures a face image in which the face of the occupant is captured by the image sensor and transmits the captured face image to the control device 200. Then, based on the face image photographed by the measurement unit 121, the environment control unit 233, for example, if the face depicted in the face image is different from the pre-registered worker's face, a warning notification and an operation history Acquire. As a result, the control device 200 can warn when a person different from a pre-registered office worker gets on the seat, so that security can be improved.
