Description

[Technical Field]

[0001] The present disclosure relates to a server device, a device control system, a control method, and a program. [Background technology]

[0002] In recent years, lighting devices capable of changing the illuminance and color temperature of the light they emit have become widespread. It is known that the illuminance and color temperature of such lighting devices affect the mental and physical state of a user. For example, bright bluish-white light (light with a high color temperature) such as that of a daylight or coulour-coloured fluorescent lamp will give the user a refreshing feeling if the illuminance is high, but will give the user a gloomy and cold feeling if the illuminance is too low. On the other hand, reddish light (light with a low color temperature), such as that emitted by an incandescent bulb, gives the user a feeling of calmness when the illuminance is low, but gives the user a feeling of heat when the illuminance is too high.

[0003] As an example of lighting equipment technology that utilizes such properties, Patent Document 1 discloses a lighting equipment (lighting device) that automatically controls the illuminance and color temperature of the lighting equipment in accordance with the preferences of the user. [Prior art documents] [Patent documents]

[0005] However, in reality, the illuminance and color temperature of a lighting device desired by a user change depending on the user's physical and mental state, and are not uniquely determined. Therefore, if lighting devices are controlled to achieve a preset illuminance and color temperature, as described in the above-mentioned Patent Document 1, it is not possible to respond to such changes, and in some cases, this may worsen the user's physical and mental state.

[0006] The present disclosure has been made in consideration of the above circumstances, and aims to provide a server device, a device control system, a control method, and a program that can appropriately control control target devices, including lighting devices, in accordance with the physical and mental state of a user.

[0010] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference numerals. The embodiments described below are for illustrative purposes only and do not limit the scope of the present invention. Therefore, those skilled in the art may employ embodiments in which each or all of the elements are replaced with equivalents, and these embodiments are also within the scope of the present invention.

[0011] (Embodiment 1) 1 is a block diagram showing the overall configuration of a device control system 1 according to a first embodiment of the present disclosure. As an example, the device control system 1 includes a server device 10, a lighting device 20, a biosensor 30, and a terminal device 40. The server device 10, the lighting devices 20, the biosensors 30, and the terminal devices 40 are communicably connected via a network NT, such as the Internet.

[0012] The server device 10 is, for example, a server computer, and is installed in a location different from the building in which the lighting devices 20 are installed. As an example, the server device 10 may be a cloud server provided on the network NT. The server device 10 may be installed in the building in which the lighting devices 20 are installed.

[0013] The server device 10 repeatedly acquires the user's biometric information detected by the biometric sensor 30 via the network NT and controls the lighting devices 20 in accordance with the acquired biometric information. The server device 10 then estimates the user's physical and mental state based on the change in the biometric information before and after the control. The server device 10 will be described in detail after the lighting devices 20 to the terminal device 40 have been described.

[0014] The lighting device 20 is an example of a control target device and is installed in a building used by a user (for example, a user's residence). The lighting device 20 includes, for example, multiple types of LED (Light Emitting Diode) modules, and is capable of changing the illuminance and color temperature of the emitted light in response to control from the server device 10. Although FIG. 1 shows a case where the device control system 1 includes two lighting devices 20, this is just an example, and the number of lighting devices 20 may be three or more.

[0015] The biosensor 30 is, for example, a wearable device, a vital sensor, or an infrared sensor, and detects biometric information of a user present in a building in which the lighting device 20 is installed. The biological information detected by the biological sensor 30 includes, for example, any of body temperature, pulse rate, brain waves, number of blinks, and sweating. Note that the biosensor 30 may be a wearable device, a vital sensor, or a biosensor other than an infrared sensor, and the bioinformation detected by the biosensor 30 may be other than body temperature, pulse rate, brain waves, blinking rate, and sweating.

[0016] The terminal device 40 is, for example, a smartphone, a tablet terminal, or the like used by a user, and sets necessary information for the server device 10, and also receives and displays information sent from the server device 10.

[0017] The following describes in detail the server device 10. Note that, although the following describes a case where the lighting devices 20 are controlled from the server device 10 (controller 11), as will be described later, the terminal device 40 may download control content from the server device 10 (controller 11) and control the lighting devices 20 from the terminal device 40.

[0018] The server device 10 includes a control unit 11, which is an example of an equipment control means, a memory unit 12, which is an example of a storage means, a communication unit 13, which is an example of a biometric information acquisition means and a notification means, an estimation unit 14, which is an example of an estimation means, and a learning unit 15, which is an example of a learning means. As mentioned above, the server device 10 is a computer for a server, and includes, for example, a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), auxiliary storage devices such as HDD (Hard Disk Drive) and SSD (Solid State Drive), and communication units such as wired LAN and wireless LAN. The server device 10 realizes a control unit 11, an estimation unit 14, a learning unit 15, etc., by, for example, a CPU using RAM as a working memory and executing a program stored in a ROM or an auxiliary storage device to appropriately control the communication unit.

[0019] The control unit 11 controls the communication unit 13 to repeatedly acquire biometric information from the biometric sensor 30 via the network NT. Then, the control unit 11 controls the lighting device 20 in accordance with the acquired biometric information. 2 is stored in the storage unit 12, the control unit 11 controls the lighting device 20 in accordance with the control content defined for the corresponding operation mode when the value of the acquired biological information (e.g., pulse rate) exceeds a threshold value. That is, the control unit 11 changes the illuminance and color temperature of the lighting device 20.

[0020] Returning to FIG. 1, the storage unit 12 stores the control table as shown in FIG. 2 described above, and also accumulates and stores the biometric information acquired from the biometric sensor 30. The control table shown in FIG. 2 can be set by the user from the terminal device 40, for example.

[0021] The communication unit 13 is, for example, a wired or wireless communication unit, and is connected to the network NT. The communication unit 13 acquires biometric information from the biometric sensor 30 under the control of the control unit 11. Furthermore, the communication unit 13 sends commands from the control unit 11 to the lighting devices 20. In addition, the communication unit 13, under the control of the control unit 11, notifies the terminal device 40 of a message addressed to the user. For example, before the control unit 11 starts controlling the lighting device 20, the communication unit 13 notifies the terminal device 40 of a message MS1 as shown in FIG. This message MS1 includes a request for the user to approve the control of the lighting device 20. If the user does not approve, the user presses the cancel button BT1, and if the user approves, the user presses the start button BT2. Furthermore, when the control unit 11 controls the lighting device 20, the communication unit 13 notifies the terminal device 40 of a message MS2 as shown in FIG. 3(b).

[0022] Returning to FIG. 1, the estimation unit 14 estimates the mental and physical state of the user based on changes in the biological information before and after the control performed by the control unit 11. More specifically, the estimation unit 14 estimates whether or not there is an effect on the user's physical and mental state based on whether or not the difference between the value of the biometric information before control by the control unit 11 and the value of the biometric information after control by the equipment control means exceeds a reference value. That is, the estimation unit 14 estimates that there was an effect on the user's mental and physical state when the difference in the biometric information before and after the control exceeds a reference value, and estimates that there was no effect on the user's mental and physical state when the difference in the biometric information before and after the control is within the reference value.

[0023] The learning unit 15 learns an operation mode suitable for the user according to the presence or absence of the effect estimated by the estimation unit 14.

[0024] The operation of the device control system 1 according to the first embodiment will be described below with reference to FIG. 4 is a flowchart illustrating the device control process executed by the server device 10. This device control process is repeatedly executed, for example, every time a certain period of time has elapsed. That is, when the process returns to the first step S101, the process is restarted from step S101 after the certain period of time has elapsed.

[0025] First, the server device 10 acquires biometric information (step S101). That is, the control unit 11 controls the communication unit 13 to acquire, from the biosensor 30, the current biometric information detected by the biosensor 30. Such step S101 is an example of a biometric information acquisition step.

[0026] The server device 10 determines whether the value of the biometric information exceeds a threshold value (step S102). That is, the control unit 11 refers to the control table shown in FIG. 2 stored in the storage unit 12 and determines whether the value of the biological information (for example, pulse rate) acquired in step S101 above exceeds a threshold value.

[0027] If the server device 10 determines that the value of the biometric information does not exceed the threshold value (step S102; No), the process returns to step S101 described above.

[0028] On the other hand, if it is determined that the value of the biological information exceeds the threshold value (step S102; Yes), the server device 10 determines whether or not to request the user for approval of device control (step S103). It should be noted that whether or not the user is requested to approve the device control can be set by the user at his / her discretion, and the setting contents are registered in the storage unit 12.

[0029] When the server device 10 determines that it does not request the user to approve the device control (step S103; No), the server device 10 proceeds to step S106, which will be described later.

[0030] On the other hand, if it is determined that approval for device control is to be requested from the user (step S103; Yes), the server device 10 requests approval for device control from the user (step 104). For example, the control unit 11 controls the communication unit 13 to notify the terminal device 40 of the message MS1 shown in FIG.

[0031] The server device 10 determines whether the user has approved the device control (step 105). For example, when the cancel button BT1 is pressed on the terminal device 40 that notified the message MS1 shown in FIG. 3(a), the control unit 11 determines that the user has not approved, and when the start button BT2 is pressed, the control unit 11 determines that the user has approved. If neither button BT1 nor BT2 is pressed after a certain period of time has elapsed, the control unit 11 may determine that the user has not approved.

[0032] If the server device 10 determines that the user has not approved the device control (step 105; No), the process returns to step S101 described above.

[0033] On the other hand, if it is determined that the user has approved the device control (step S105; Yes), the server device 10 implements the device control (step S106). For example, the control unit 11 determines the operation mode by referring to the control table shown in FIG. 2 stored in the storage unit 12, and controls the lighting devices 20 in accordance with the control content corresponding to the determined operation mode.

[0034] The server device 10 determines whether to notify the user of the implementation of device control (step S107). It should be noted that whether or not to notify the user of the implementation of device control can be set by the user at will, and the setting contents are registered in the storage unit 12.

[0035] When the server device 10 determines that the user will not be notified of the implementation of device control (step S107; No), the server device 10 proceeds to step S109, which will be described later.

[0036] On the other hand, if it is determined that the user should be notified of the implementation of device control (step S107; Yes), the server device 10 notifies the user of the implementation of device control (step 108). For example, the control unit 11 controls the communication unit 13 to notify the terminal device 40 of the message MS2 shown in FIG.

[0037] The server device 10 determines whether or not the device control has been effective (step S109). For example, the estimation unit 14 acquires current biometric information from the biometric sensor 30 via the communication unit 13 within a predetermined time after the control, compares the value of the biometric information before the control with the value of the biometric information after the device control, and determines that the device control was effective if the difference exceeds a reference value.Furthermore, the estimation unit 14 determines that the device control was ineffective if the difference between the value of the biometric information before the control and the value of the biometric information after the control is within a reference value.

[0038] When the server device 10 determines that the device control has been effective (step S109; Yes), the server device 10 returns the process to the above-mentioned step S101.

[0039] On the other hand, if it is determined that the device control has not been effective (step S109; No), the server device 10 changes the operation mode (step S110). For example, the control unit 11 changes the operation mode to one that is expected to be more effective, in accordance with the learning result of the learning unit 15. Then, the server device 10 returns the process to step S101 described above.

[0040] In the above-described first embodiment, the case where the messages MS1 and MS2 shown in FIGS. 3(a) and 3(b) are transmitted to the terminal device 40 has been described, but it is also possible to allow the user to visually confirm changes in the biological information. For example, the control unit 11 may cause the terminal device 40 to display a monitor screen as shown in Fig. 5. On this monitor screen, for example, the changes in body temperature and heart rate are shown in graphs. The graphs also indicate the periods of each operation mode in a distinguishable manner.

[0041] In the first embodiment described above, the estimation unit 14 determines whether or not there is an effect. However, the user may manually reply to the server device 10 from the terminal device 40 whether or not there is an effect.

[0042] As described above, the device control system 1 according to the first embodiment automatically estimates the user's physical and mental state and controls the devices according to the estimation result, eliminating the need for the user to determine their own physical and mental state and make complicated changes to the device control. Note that when control of the lighting devices 20 is not required, the user can easily turn the lighting devices 20 on and off using the terminal device 40.

[0043] As a result, it is possible to appropriately control the control target devices, including lighting devices, in accordance with the mental and physical state of the user.

[0044] (Embodiment 2) In the first embodiment described above, the case where the lighting devices 20 are controlled has been described. However, other types of control target devices may also be controlled in cooperation with each other, in addition to the lighting devices 20. Hereinafter, a device control system 2 according to a second embodiment will be described, which is characterized by controlling a plurality of types of control target devices in cooperation with each other.

[0045] 6 is a block diagram showing an overall configuration of a device control system 2 according to a second embodiment of the present disclosure. As an example, the device control system 2 includes a server device 10, lighting devices 20, air conditioners 50, a biosensor 30, and a terminal device 40. The server device 10, the lighting devices 20, the air conditioners 50, the biosensors 30, and the terminal devices 40 are communicably connected via a network NT, such as the Internet.

[0046] That is, the device control system 2 has a configuration in which an air conditioning device 50 is added to the device control system 1 shown in Fig. 1 described above. Note that the air conditioning device 50 is an example of a device to be controlled, and other devices may be electric fans, audio equipment, etc. Furthermore, although FIG. 6 shows a case where the device control system 2 includes one air conditioning device 50, this is just an example, and the number of air conditioning devices 50 may be two or more.

[0047] The configuration of the server device 10 is the same as that of the first embodiment. Nevertheless, the storage unit 12 stores a control table as shown in Fig. 7 instead of the control table shown in Fig. 2. The control table as shown in Fig. 7 can also be set by the user from the terminal device 40, for example.

[0048] When the value of the acquired biological information (for example, pulse rate) exceeds a threshold, the control unit 11 controls the lighting devices 20 and the air conditioners 50 in accordance with the control content defined for the corresponding operation mode. That is, the server device 10 according to the second embodiment also executes the device control process shown in FIG.

[0049] Therefore, the device control system 2 according to the second embodiment automatically estimates the user's physical and mental state and controls the devices according to the estimation result, so that the user does not need to judge his or her own physical and mental state and make complicated changes to the device control. Note that when control of the lighting devices 20 and air conditioning devices 50 is not required, the user can easily turn them on / off from the terminal device 40.

[0050] As a result, it is possible to appropriately control the control target devices, including lighting devices, in accordance with the mental and physical state of the user.

[0051] (Other embodiments) Although the first and second embodiments of the present disclosure have been described above, various modifications and applications are possible in implementing the present disclosure.

[0052] In the above-described first and second embodiments, the server device 10 controls the control target devices (lighting devices 20, air conditioning devices 50, etc.). However, the server device 10 may determine the control content, and the determined control content may be downloaded by the terminal device 40, and the control target devices may be controlled from the terminal device 40.

[0053] In the above-described first and second embodiments, threshold values ​​are set in the control tables as shown in FIGS. 2 and 7, and the control target devices (such as the lighting devices 20 and the air conditioning devices 50) are controlled according to the control content. However, target values ​​may be set instead of threshold values. When the target value is set, for example, the control unit 11 controls the control target devices (lighting devices 20, air conditioners 50, etc.) so that the value of the biological information approaches the target value. Note that when a threshold value is set as in the first and second embodiments, the frequency of device control decreases and the control range increases. For example, when the value of the acquired biological information exceeds the threshold value, the control unit 11 controls the lighting device 20 and the like, and at that time, changes the illuminance and color temperature by a relatively large amount. On the other hand, when a target value is set, the frequency of device control increases and the control range becomes narrower. For example, the control unit 11 controls the lighting device 20 etc. so that the value of the acquired biological information approaches the target value, and at that time, changes the illuminance and color temperature by a relatively small amount.

[0054] In the above-described first and second embodiments, the control unit 11 controls the communication unit 13 to acquire biometric information from the biometric sensor 30 every time a certain period of time has elapsed, but the timing of acquiring the biometric information may be changed as appropriate. For example, the control unit 11 changes the frequency of acquiring biometric information depending on the mental and physical state of the user estimated by the estimation unit 14. Specifically, when the estimation unit 14 determines that the device control has been effective, the control unit 11 decreases the frequency of acquiring biometric information. That is, the control unit 11 acquires biometric information at longer time intervals than specified. On the other hand, when the estimation unit 14 determines that the device control has not been effective, the control unit 11 increases the frequency of acquiring biometric information. That is, the control unit 11 acquires biometric information at shorter time intervals than specified. When controlling the lighting device 20, the control unit 11 controls the illuminance and the color temperature within a specified range of change and at a time interval equal to or greater than a specified value so as not to change the illuminance and the color temperature suddenly.

[0055] In the above-described first and second embodiments, the control unit 11, the estimation unit 14, the learning unit 15, etc. are realized by the CPU using the RAM as a work memory and executing a program stored in the ROM or an auxiliary storage device. However, each of these functions may be realized by dedicated hardware. The dedicated hardware may be, for example, a single circuit, a composite circuit, a programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a combination thereof.

[0056] In addition, by applying a program that defines the operation of the server device 10 according to the above-mentioned first and second embodiments to an existing personal computer or information terminal device, it is possible to make the personal computer or information terminal device function as the server device 10 according to the first and second embodiments.

[0057] Furthermore, the method of distribution of such a program is arbitrary; for example, it may be stored on a computer-readable recording medium such as a CD-ROM (Compact Disk Read-Only Memory), a DVD (Digital Versatile Disk), or a memory card and distributed, or it may be distributed via a communication network such as the Internet.

[0058] The present disclosure allows various embodiments and modifications without departing from the broad spirit and scope of the present disclosure. Furthermore, the above-described embodiments are intended to explain the present disclosure and do not limit the scope of the present disclosure. That is, the scope of the present disclosure is defined by the claims, not the embodiments. Various modifications made within the scope of the claims and the meaning of equivalent disclosures are considered to be within the scope of the present disclosure.
