DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, the embodiments will be described in detail with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component arrangement and connection forms, steps, and order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. In addition, among the components in the following embodiments, components that are not described in the independent claims will be described as optional components.

[0010] In addition, each drawing is a schematic diagram and is not necessarily a precise illustration. In each drawing, the same reference numerals are used for substantially the same configurations, and duplicated explanations may be omitted or simplified.

[0011] (Embodiment) [composition] First, an overview of a device control system according to an embodiment will be described. FIG. 1 is a block diagram showing a functional configuration of a device control system according to an embodiment. A device control system 10 according to an embodiment is a PoE system (a system based on PoE) that controls a target device by utilizing a PoE mechanism. The device control system 10 includes a power supply device 20 (PSE: Power Sourcing Equipment), one or more power receiving devices (PD: Powered Devices), and a battery device 90. The power receiving devices are devices having a PD interface, and in FIG. 1, each of a lighting device 30, a disaster prevention device 40, a camera 50, and an air conditioning device 60 corresponds to a power receiving device. The power receiving devices may be audio devices (speakers), video devices, wireless devices, sensors, user interface devices, or the like.

[0012] The battery device 90 is connected to the connection port 21 of the power supply device 20 via the standard cable 70, and is connected to each power receiving device on the opposite side. For example, the battery device 90 is connected to the connection port 21 of the power supply device 20 via the standard cable 70, and is connected to the lighting device 30 on the opposite side. Alternatively, the battery device 90 is connected to the connection port 21 of the power supply device 20 via the standard cable 70, and is connected to the disaster prevention device 40 on the opposite side.

[0013] The power supply device 20 includes a plurality of connection ports 21, a control unit 22, a storage unit 23, a detection unit 24, and a signal transmission unit 25. The plurality of connection ports 21 are connection structures (connectors) to which standard cables 70 conforming to the Ethernet (registered trademark) standard are connected. Specifically, the standard cables 70 are so-called LAN (Local Area Network) cables or the like. The power receiving devices are electrically connected to the connection ports 21 via the standard cables 70. The power receiving devices (lighting devices 30, disaster prevention devices 40, cameras 50, and air conditioning devices 60) can receive power from the power supply device 20 via the standard cables 70 and can communicate with the power supply device 20 via the standard cables 70.

[0014] The control unit 22 supplies power to the power receiving device connected to the connection port 21. The control unit 22 also controls the power receiving device connected to the connection port 21 by transmitting a control signal to the power receiving device via the standard cable 70. The control unit 22 is specifically realized by a microcomputer or a processor, and is built into the power supply device 20. The functions of the control unit 22 are realized, for example, by the microcomputer or processor constituting the control unit 22 executing a computer program stored in the storage unit 23.

[0015] The storage unit 23 is a storage device that stores the computer programs and various information necessary for controlling the power receiving device, etc. The storage unit 23 is realized by, for example, a semiconductor memory.

[0016] The detection unit 24 detects whether or not the power supplied to the power supply device 20 has been interrupted. Specifically, the detection unit 24 may detect the presence or absence of a current supplied to the power supply device 20. Note that the detection unit 24 may detect whether or not the power supplied to the power supply device 20 has been interrupted by a method other than the above-mentioned method.

[0017] The signal transmission unit 25 transmits a signal to the battery device 90. For example, when the detection unit 24 detects that the power supplied to the power supply device 20 has been cut off, the signal transmission unit 25 transmits a battery operation stop signal to the battery device 90 so as to stop the operation of the battery device 90 to supply power to the power receiving device.

[0018] The lighting device 30 operates by receiving power supply from the power supply device 20. The lighting device 30 is, for example, a lighting device that illuminates an indoor space, and more specifically, is a base light, a system ceiling light, a down light, a spot light, or an emergency light. The specific embodiment of the lighting device 30 is not particularly limited. The device control system 10 includes one lighting device 30, but may include two or more lighting devices 30. The lighting device 30 includes a light-emitting element 31 and a light-emission control unit 32.

[0019] The disaster prevention device 40 includes a sensor 41 and a detection control unit 42. The detection control unit 42 is a processor that operates by receiving power supply from the power supply device 20. The detection control unit 42 may include a communication circuit. The detection control unit 42 receives a signal from the power supply device 20 and operates based on the received signal. In addition, the sensor 41 transmits a detected signal to the detection control unit 42. The detection control unit 42 performs an operation of detecting an object through the sensor 41. The detection control unit 42 may communicate with the power supply device 20.

[0020] The camera 50 includes an imaging element 51 and an imaging control unit 52. The imaging element 51 converts light into an electrical signal by photoelectric conversion due to the photoelectric effect, thereby converting an image into an electrical signal. The imaging control unit 52 is a processor that operates by receiving power supply from the power supply device 20. The imaging control unit 52 may include a communication circuit. The imaging control unit 52 receives a signal from the power supply device 20 and operates based on the received signal. The imaging control unit 52 captures an image of a target through the imaging element 51. The imaging control unit 52 may communicate with the power supply device 20.

[0021] The air conditioning equipment 60 includes an air conditioning control unit 62 and a heat exchanger 61. The heat exchanger 61 removes hot or cold heat from the outside air by bringing the taken-in outside air into contact with a refrigerant, and generates air whose temperature and humidity have been adjusted. The air conditioning control unit 62 is a processor that operates by receiving power supply from the power supply equipment 20. The air conditioning control unit 62 may include a communication circuit. The air conditioning control unit 62 receives a signal from the power supply equipment 20 and operates based on the received signal. The air conditioning control unit 62 generates air whose temperature and humidity have been adjusted through the heat exchanger 61. The air conditioning control unit 62 may communicate with the power supply equipment 20.

[0022] The battery device 90 includes a battery 91, a battery control unit 92, a signal receiving unit 93, and a battery storage unit 94. The battery 91 is a secondary battery that is charged before use. The battery 91 is, for example, a lithium ion battery, but may be a nickel-metal hydride battery. The battery 91 includes an electrode and an active material. The battery 91 may include an electrolyte instead of the active material. The battery control unit 92 performs control so as to supply power to the power supply device 20 when the power supply is cut off. The signal receiving unit 93 receives a signal transmitted from the signal transmitting unit 25 of the power supply device 20. The battery storage unit 94 stores the signal received by the signal receiving unit 93.

[0023] The battery device 90 is normally supplied with AC power from the power supply device 20 that receives AC power from the power supply system during normal operation (when the system power supply is not interrupted). The battery device 90 charges a battery 91 provided in the battery device 90 with the AC power received from the power supply device 20.

[0024] On the other hand, when the power supply is cut off (when the system power supply is cut off), the battery device 90 supplies the DC power that has been charged in the battery 91 to the power receiving device by discharging the battery 91.

[0025] [Control of stopping operation of battery device by signal] Next, a description will be given of the control of stopping the operation of the battery device by the device control system 10. Fig. 2 is a flowchart showing the control of stopping the operation of the battery device by the device control system 10 according to the embodiment.

[0026] First, the detection unit 24 detects whether the power supply to the power supply device 20 has been cut off (step S100). When the detection unit 24 detects that the power supply to the power supply device 20 has been cut off (Yes in step S100), the power supply from the power supply device 20 to the battery device 90 and the power receiving device is stopped. Therefore, the battery device 90 supplies power to the power receiving device instead of the power supply device 20 (S101). Specifically, the battery control unit 92 supplies power to the power receiving device by discharging the battery 91. Note that the battery control unit 92 can regard the cutoff of the power supply to the battery device 90 from the power supply device 20 as the cutoff of the power supply to the power supply device 20.

[0027] On the other hand, when the detection unit 24 does not detect that the power supply to the power supply device 20 has been cut off, that is, when power is being supplied to the power supply device 20 as usual (No in step S100), the control unit 22 determines whether or not to stop the power supply to the battery device 90 and the power receiving device through the connection port 21 (step S102). For example, when an operation to turn off the power receiving device is performed on a user interface device (not shown) connected to another connection port 21, the control unit 22 determines to stop the power supply to the battery device 90 and the power receiving device through the connection port 21 (Yes in step S102).

[0028] At this time, if the power supply to the battery device and the power receiving device is simply stopped, the battery device 90 will supply power to the power receiving device as in step S101, and the power receiving device will not be turned off. Therefore, the signal transmission unit 25 transmits a battery operation stop signal to the battery device 90 (step S103). When the battery operation stop signal is received by the signal reception unit 93 of the battery device 90, the battery control unit 92 stores the received battery operation stop signal in the battery storage unit 94 (step S104). In a state in which the battery operation stop signal is stored in the battery storage unit 94, the battery control unit 92 stops the operation described in the above step S101, that is, the operation of discharging the battery 91 and supplying power to the power receiving device (step S105). Therefore, the power receiving device is appropriately turned off in accordance with the operation to turn off the power receiving device.

[0029] On the other hand, if the control unit 22 determines not to stop (continue) the power supply to the battery device 90 and the power receiving device through the connection port 21 (No in step S102), the control unit 22 maintains the power supply to the battery device and the power receiving device through the connection port 21 (step S106).

[0030] [Controlling restart of battery device operation by signal] Next, a description will be given of control of restarting the operation of the battery device 90 that has stopped operating based on the battery operation stop signal. Fig. 3 is a flowchart showing control of restarting the operation of the battery device 90 that has stopped operating based on the battery operation stop signal according to the embodiment.

[0031] The control unit 22 of the power supply device 20 determines whether or not to resume power supply to the battery device 90 and the power receiving device through the connection port 21 (step S200). For example, when an operation to turn on the power receiving device is performed on a user interface device (not shown) connected to another connection port 21, the control unit 22 determines to resume power supply to the battery device 90 and the power receiving device through the connection port 21 (Yes in step S200).

[0032] At this time, the control unit 22 resumes the power supply to the battery device 90 and the power receiving device through the connection port 21 (step S201). Next, the signal transmission unit 25 transmits a battery operation stop release signal to the battery device 90 (step S202). When the battery operation stop release signal is received by the signal reception unit 93 of the battery device 90, the battery control unit 92 erases (invalidates) the battery operation stop signal stored in the battery storage unit 94 (step S203). In a state in which the battery operation stop signal is not stored in the battery storage unit 94, the battery control unit 92 performs the operation described in the above step S101, that is, the operation of discharging the battery 91 and supplying power to the power receiving device. Therefore, even if the power supply to the power supply device 20 is interrupted for some reason, the power receiving device can continue to operate by receiving power from the battery device 90.

[0033] On the other hand, if no operation to turn on the power receiving device is performed on the user interface device (not shown), the control unit 22 determines not to resume power supply to the battery device 90 and the power receiving device through the connection port 21 (No in step S200), and the operation ends.

[0034] [Power consumption of battery equipment and power receiving devices] The battery device 90 may include an interface unit such as a PD interface as described below. The interface unit such as a PD interface included in the battery device 90 is realized by, for example, a battery control unit 92. The power supply device 20 acquires information about the power receiving device from the battery control unit 92. The information about the power receiving device is a power consumption value that is greater than the sum of the power consumption required for charging the battery device 90 and the power consumption of the power receiving device. The power supply device 20 supplies power to the battery device 90 and the power receiving device based on the information about the power receiving device acquired from the battery control unit 92, which also functions as an interface unit. In this way, the power supply device 20 can acquire information about the power receiving device from the battery control unit 92, which also functions as an interface unit, and supply power sufficient to cover both the power consumption required for charging the battery device 90 and the power consumption of the power receiving device.

[0035] [Adjusting the power used for charging based on the power consumption of the receiving device] Next, adjustment of power used for charging depending on the power consumption of the power receiving device of the device control system 10 will be described. Fig. 4 is a flowchart showing the operation of adjusting power used for charging depending on the power consumption of the power receiving device of the device control system 10 according to the embodiment. The power supply device 20 performs the following operation while supplying power to the power receiving device.

[0036] The control unit 22 determines whether the power consumption of the power receiving device is greater than a predetermined value (step S300). The control unit 22 may obtain the value of the power consumption of the power receiving device from an interface unit provided in the battery device 90, or may obtain the value of the power consumption of the power receiving device from an interface unit provided in the power receiving device.

[0037] When the control unit 22 determines that the power consumption of the power receiving device is greater than a predetermined value (Yes in step S300), the control unit 22 reduces the power used to charge the battery device 90 (step S301). For example, the control unit 22 transmits a signal to the battery device 90 to instruct the battery device 90 to reduce the power used to charge the battery device 90. Then, the signal receiving unit 93 of the battery device 90 receives the signal, and performs control so that the battery control unit 92 reduces the power used to charge the battery 91.

[0038] When the control unit 22 determines that the power consumption of the power receiving device is not greater than the predetermined value (No in step S300), the control unit 22 maintains the power used to charge the battery device 90 (step S302).

[0039] [Change the number of receiving devices depending on remaining charge] Next, an operation of changing the number of power receiving devices depending on the remaining charge of the battery device 90 of the device control system 10 will be described. Fig. 5 is a flowchart showing an operation of changing the number of power receiving devices depending on the remaining charge of the battery device 90 of the device control system according to the embodiment. The power supply device 20 performs the following operation while the battery device 90 is supplying power to the power receiving devices.

[0040] The control unit 22 determines whether the remaining charge of the battery device 90 is equal to or less than a predetermined value (step S400). The control unit 22 may receive a signal from the battery control unit 92 of the battery device 90 to determine whether the remaining charge of the battery 91 is equal to or less than a predetermined value. The battery control unit 92 may transmit a signal indicating the value of the remaining charge of the battery 91 to the control unit 22.

[0041] When the control unit 22 determines that the remaining charge of the battery device 90 is equal to or less than a predetermined value (Yes in step S400), the control unit 22 reduces the number of power receiving devices to which power from the battery 91 of the battery device 90 is supplied (step S401). At this time, the control unit 22 may transmit a battery operation stop signal to the battery device 90 to reduce the number of power receiving devices to which power is supplied from the battery device 90.

[0042] When the control unit 22 determines that the remaining charge of the battery device 90 is not equal to or less than a predetermined value (No in step S400), the control unit 22 maintains the number of power receiving devices to which power from the battery 91 of the battery device 90 is supplied (step S402). At this time, the control unit 22 may maintain the number of power receiving devices to which power is supplied from the battery device 90 without transmitting a battery operation stop signal to the battery device 90.

[0043] [Change dimming ratio based on remaining battery charge] Next, an operation of changing the dimming level of the lighting device 30 depending on the remaining charge of the battery device 90 in the device control system 10 will be described. Fig. 6 is a flowchart showing an operation of changing the dimming level of the lighting device 30 depending on the remaining charge of the device control system according to the embodiment. The power supply device 20 performs the following operation while the battery device 90 is supplying power to the power receiving device.

[0044] The control unit 22 determines whether the remaining charge of the battery device 90 is equal to or lower than a predetermined value (step S500). The control unit 22 may receive a signal from the battery control unit 92 of the battery device 90 to determine whether the remaining charge of the battery 91 is equal to or lower than a predetermined value.

[0045] When the control unit 22 determines that the remaining charge of the battery device 90 is equal to or less than a predetermined value (Yes in step S500), the control unit 22 dims the light of the lighting device 30, which is a power receiving device (step S501). That is, the control unit 22 reduces the dimming level of the lighting device 30, which is a power receiving device. At this time, the signal transmission unit 25 may transmit a signal related to the dimming level to the lighting device 30, which is a power receiving device.

[0046] When the control unit 22 determines that the remaining charge of the battery device 90 is not equal to or less than the predetermined value (No in step S500), the control unit 22 maintains the dimming of the lighting device 30, which is the power receiving device (step S502). In other words, the control unit 22 maintains the dimming level of the lighting device 30, which is the power receiving device.

[0047] [Change in the number of power receiving devices depending on the time when the power supply was interrupted] Next, an operation of changing the number of power receiving devices depending on the length of time that the power supply to the power supply device 20 of the device control system 10 is interrupted will be described. Fig. 7 is a flowchart showing an operation of changing the number of power receiving devices depending on the length of time that the power supply interruption occurred in the device control system 10 according to the embodiment. The power supply device 20 performs the following operation while the battery device 90 is supplying power to the power receiving devices.

[0048] The control unit 22 determines whether the length of time during which the power supply to the power supply device 20 was interrupted is equal to or longer than a predetermined time (step S600). For example, the detection unit 24 detects whether power is being supplied to the power supply device 20, and the control unit 22 acquires the result of detection by the detection unit 24. Then, the control unit 22 determines whether the length of time during which the power supply to the power supply device 20 was interrupted is equal to or longer than a predetermined time based on the acquired result.

[0049] When the control unit 22 determines that the length of time during which the power supply to the power supply device 20 has been cut off is equal to or longer than a predetermined time (Yes in step S600), the power supply device 20 reduces the number of power receiving devices to which it supplies power (step S601). At this time, the control unit 22 may transmit a battery operation stop signal to the battery device 90 to reduce the number of power receiving devices to which power is supplied from the battery device 90.

[0050] When the control unit 22 determines that the length of time during which the power supply to the power supply device 20 has been cut off is not equal to or longer than a predetermined time (No in step S600), the power supply device 20 maintains the number of power receiving devices to which it supplies power (step S602). At this time, the control unit 22 may maintain the number of power receiving devices to which power is supplied from the battery device 90 without transmitting a battery operation stop signal to the battery device 90.

[0051] [Change in dimming ratio depending on the time when the power supply was interrupted] Next, an operation of changing the dimming level of the lighting device 30 depending on the length of time that the power supply to the power supply device 20 of the device control system 10 is interrupted will be described. Fig. 8 is a flowchart showing an operation of changing the dimming level of the lighting device 30 depending on the length of time that the power supply to the device control system 10 is interrupted according to the embodiment. The power supply device 20 performs the following operation while the battery device 90 is supplying power to the power receiving device.

[0052] The control unit 22 determines whether the length of time during which the power supply to the power supply device 20 was interrupted is equal to or longer than a predetermined time (step S700). The detection unit 24 may detect the presence or absence of power supply to the power supply device 20 from a power grid or the like, and the control unit 22 may obtain the result of the detection by the detection unit 24 and determine the length of time during which the power supply from the power grid to the power supply device 20 was interrupted.

[0053] When the control unit 22 determines that the length of time during which the power supply to the power supply device 20 has been interrupted is equal to or longer than the predetermined time (Yes in step S700), the control unit 22 dims the light of the lighting device 30, which is a power receiving device (step S701). That is, the control unit 22 reduces the dimming level of the lighting device 30, which is a power receiving device. At this time, the signal transmission unit 25 may transmit a signal related to the dimming level to the lighting device 30, which is a power receiving device.

[0054] When the control unit 22 determines that the length of time during which the power supply to the power supply device 20 has been interrupted is not equal to or longer than the predetermined time (No in step S700), the control unit 22 maintains the dimming of the lighting device 30, which is a power receiving device (step S702). In other words, the control unit 22 maintains the dimming level of the lighting device 30, which is a power receiving device.

[0055] [Effects, etc.] The device control system 10 of the present disclosure comprises a power supply device 20 having a connection port 21, a power receiving device, and a battery device 90 having a battery 91, charging the battery 91 using a portion of the power supplied from the power supply device 20 through the connection port 21, and supplying another portion of the power supplied from the power supply device 20 through the connection port 21 to the power receiving device, wherein when the power supply to the power supply device 20 is cut off, the battery device 90 supplies power to the power receiving device by discharging the battery 91, and when the power supply to the power supply device 20 is not cut off and the power supply through the connection port 21 is to be stopped, the power supply device 20 instructs the battery device 90 to stop operating.

[0056] As a result, the device control system 10 of the present disclosure can prevent the battery from erroneously supplying power to the power receiving device when the power supply from the power supply device 20 is intentionally cut off.

[0057] Also, for example, in the device control system 10 of the present disclosure, the power supply device 20 issues an instruction by transmitting a battery operation stop signal to the battery device 90, and the battery device 90 stops its operation based on the received battery operation stop signal, and when the power supply device 20 resumes power supply through the connection port 21, it transmits a battery operation stop release signal to the battery device 90, and the battery device 90 releases the stop of its operation based on the received battery operation stop release signal.

[0058] As a result, the device control system 10 of the present disclosure can prevent the battery device 90 from supplying power to the power receiving device when the power supply device 20 does not supply power through the connection port 21 by transmitting a signal related to the operation of the battery device 90 to the battery device 90. Therefore, the device control system 10 of the present disclosure can prevent the battery device 90 from erroneously supplying power to the power receiving device when the power supply device 20 intentionally cuts off the power supply from the power supply device 20.

[0059] Also, for example, in the device control system 10 of the present disclosure, the power receiving device is the lighting device 30.

[0060] As a result, the device control system 10 of the present disclosure can prevent the battery from erroneously supplying power to the lighting device 30 when the power supply from the power supply device 20 is intentionally cut off.

[0061] Furthermore, for example, in the device control system 10 of the present disclosure, the lighting device 30 is a base light, a system ceiling light, a downlight, or a spotlight.

[0062] This allows the device control system 10 of the present disclosure to supply power to various lighting devices 30 appropriately.

[0063] Also, for example, in the device control system 10 of the present disclosure, the battery device 90 further includes an interface unit through which the power supply device 20 reads information about the power receiving device, and the interface unit stores, as the information about the power receiving device, a power consumption value that is greater than the sum of the power consumption required to charge the battery device 90 and the power consumption of the power receiving device.

[0064] As a result, the device control system 10 of the present disclosure can read information about the power receiving device from the battery memory unit 94, which also functions as an interface unit, and supply sufficient power to cover both the power consumption required to charge the battery device 90 and the power consumption of the power receiving device.

[0065] Furthermore, in the device control system 10 of the present disclosure, the power supply device 20 reduces the power used to charge the battery device 90 when the power consumption of the power receiving device is greater than a predetermined value.

[0066] This enables the device control system 10 to ensure the power consumption required for the power receiving device.

[0067] Also, for example, in the device control system 10 of the present disclosure, the power supply device 20 changes the number of power receiving devices to which it supplies power in accordance with the remaining charge of the battery device 90.

[0068] This allows the device control system 10 to supply power preferentially to a power receiving device that has a high need for power.

[0069] Furthermore, for example, in the device control system 10 of the present disclosure, the power supply device 20 changes the dimming level of the lighting device 30 in accordance with the remaining charge level of the battery device 90.

[0070] This allows the device control system 10 to adjust the power consumption of the power receiving device according to the remaining charge of the battery device 90.

[0071] Also, for example, in the device control system 10 of the present disclosure, the power supply device 20 changes the number of power receiving devices to which it supplies power depending on the time during which the power supply to the power supply device 20 was cut off.

[0072] This allows the device control system 10 to supply power preferentially to a power receiving device that has a high need for power.

[0073] Also, for example, in the device control system 10 of the present disclosure, the power supply device 20 changes the dimming level of the lighting device 30 depending on the time during which the power supply device 20 is turned off.

[0074] This allows the device control system 10 of the present disclosure to adjust the power consumption of the power receiving device according to the remaining charge of the battery device 90.

[0075] Furthermore, for example, in the device control system 10 of the present disclosure, the power receiving device is an air conditioner, a camera, a speaker, a disaster prevention device, a sensor, a wireless device, or a user interface device.

[0076] This allows the device control system 10 of the present disclosure to be equipped with a variety of devices.
