Description

  Embodiments described herein relate generally to an electronic apparatus.

  In recent years, home network systems that allow remote control of electronic devices such as electrical appliances installed in the home are known. In such a home network system, the operation state and power consumption of the electronic device are monitored via the network, and the operation state of the electronic device is controlled by transmitting a control signal to the electronic device via the network. For this reason, the electronic device corresponding to the home network system has a communication function for performing communication via the network. For example, the electronic device is provided with a communication adapter for communicating with an access point or the like installed in a home.

  The electronic device described above is configured to store the control state and reproduce the control state before turning off when the device is turned from the off state to the on state. In general, an electronic device having a communication function consumes more power than an electronic device having no communication function. Therefore, it is necessary to design the power source of the electronic device in consideration of the power consumed by the communication function. However, when the communication function is expanded, the electronic device corresponding to the home network system has a power source. When turned off, it is not always possible to complete processing to be executed when the power is turned off. Furthermore, in preparation for the expansion of the communication function later, when considering a configuration in which the communication function can be installed later on the electronic device, even if it is used as an electronic device having no communication function It is necessary to prepare a power supply with an excessive specification, which leads to an increase in cost. This point will be described using an example in which the electronic device is a lighting device. For example, recent lighting devices may have a function of adjusting the illuminance and color of illumination light in accordance with a user operation. Also, this type of lighting device may have a function of storing the current illuminance and color when the power is turned off and illuminating by restoring the previous illuminance and color when the power is turned on. However, when a lighting device having such a restoration function is applied to a home network system, power is also consumed for the communication function when the power is turned off, so that the process of storing illuminance and color is not completed. As a result, the illuminance and color of the illumination light may not be restored.

[Configuration of home appliance control system]
Drawing 1 is a figure showing the example of composition of household appliances control system 1 concerning an embodiment. A home appliance control system 1 shown in FIG. 1 is a system that realizes control and monitoring of home appliances installed in a home, for example, and is called a HEMS (Home Energy Management System) or the like.

The home network system 2 is constructed in, for example, a user's home or a store, and includes a gateway device 10, a user terminal 20, an access point 30, electronic devices 100 _{1 to} 100 _{3, and the} like. The number of electronic devices 100 _{1 to} 100 ₃ illustrated in FIG. 1 is merely an example, and can be changed as appropriate according to the configuration of the home network system 2.

  The gateway device 10 is a communication device that is connected to the access point 30 and connects the home network system 2 to the external network 5. In the example of FIG. 1, the gateway device 10 connects the access point 30 in the home network system 2 to the user terminal 3 and the management server 4 outside the home network system 2 via the network 5.

The user terminal 20 is, for example, a tablet terminal, a PC (Personal Computer), a mobile phone, a PDA (Personal Data Assistance), and the like, and is connected to the access point 30 via a wireless LAN (Local Area Network), a wired LAN, or the like. . The user terminal 20 transmits a control command for the electronic devices 100 _{1 to} 100 ₃ to the access point 30 according to a user operation, and displays various information regarding the electronic devices 100 _{1 to} 100 ₃ received from the access point 30.

The access point 30 communicates with the gateway device 10, the user terminal 20, and the electronic devices 100 _{1 to} 100 ₃ using a short-range wireless technology such as Bluetooth (registered trademark) or a home LAN. The access point 30 transmits various control commands input from the user terminal 20 to the electronic devices 100 _{1 to} 100 _3, and transmits various information received from the electronic devices 100 _{1 to} 100 ₃ to the user terminal 20. . The access point 30 may be formed integrally with the gateway device 10.

The electronic devices 100 _{1 to} 100 ₃ are lighting fixtures provided on, for example, a ceiling in a user's house. The electronic device 100 ₁ includes a lighting device 110 ₁ that is an electronic device and a communication adapter 120 ₁ that is a communication device. The electronic apparatus 100 ₁ is formed by attaching the communication adapter 120 ₁ to the lighting device 110 ₁ . Similarly, the electronic device 100 _2, the lighting device 110 ₂ communication adapter 120 ₂ is attached to the electronic device 100 _3, communication adapter 120 ₃ is attached to the illumination device 110 _3.

Hereinafter, when it is not necessary to distinguish between the electronic devices 100 _{1 to} 100 ₃ , they may be simply referred to as “electronic device 100”. Moreover, when it is not necessary to distinguish the illuminating devices 110 _{1 to} 110 ₃ , the illuminating devices 110 _{1 to} 110 ₃ may be simply referred to as “illuminating device 110”. When there is no need to distinguish between the communication adapters 120 _{1 to} 120 ₃ , the communication adapters 120 _{1 to} 120 ₃ may be simply expressed as “communication adapter 120”.

  The illumination device 110 has a function capable of adjusting the illuminance and color of illumination light in accordance with a user operation. The illumination device 110 has a function of storing the current illuminance and color when the power is turned off and illuminating by restoring the previous illuminance and color when the power is turned on. In addition, when the lighting device 110 receives a control command via the communication adapter 120, the lighting device 110 executes a predetermined process according to the control command. For example, when the control command is “turn on the lighting device”, the lighting device 110 turns on the power of the lighting device 110 that is the own device. When the control command is “set the illuminance of the lighting device to 80%”, the lighting device 110 sets the illuminance of the light emitted from the light source of the own device to 80%. And the illuminating device 110 transmits the execution result of various processes to the access point 30 via the communication adapter 120 as a response.

  The communication adapter 120 relays control commands and responses transmitted / received between the lighting device 110 and the access point 30. The communication adapter 120 is attached to the lighting device 110 by a contractor or user of the home network system 2.

For example, when the user terminal 20 is a mobile phone, the user can control the operation of the electronic device 100 or monitor the operation status of the electronic device 100 simply by operating the mobile phone at home.

  In FIG. 1, the user terminal 3 shown outside the home network system 2 is, for example, a mobile phone, a PDA, a tablet terminal, a PC, and the like, and is connected to the network 5 via a wireless LAN, a wired LAN, or the like. . Similar to the user terminal 20, the user terminal 3 transmits a control command for the electronic device 100 to the management server 4 according to a user operation, and displays various information regarding the electronic device 100 received from the management server 4.

  The management server 4 transmits various control commands received from the user terminal 3 to the access point 30 via the network 5. Thereby, the access point 30 transmits the control command transmitted from the user terminal 3 located outside the home network system 2 to the electronic device 100. Further, the management server 4 transmits various types of information regarding the electronic device 100 received from the access point 30 via the network 5 to the user terminal 3. As a result, the user terminal 3 displays various information related to the electronic device 100 installed in the home network system 2. As described above, even when the user of the user terminal 3 is not located in the home network system 2, the user can control the electronic device 100 and monitor the operation status of the electronic device 100.

  In such a home appliance control system 1, the electronic device 100 is provided with a dedicated power supply circuit, and the communication adapter 120 is also provided with a dedicated power supply circuit, so that the processing that the electronic device 100 should execute when the power is turned off. Allows you to complete. Hereinafter, the electronic device 100 according to the embodiment will be described in detail.

[Configuration of electronic equipment]
FIG. 2 is a diagram schematically illustrating a configuration example of the electronic device 100 according to the embodiment. As shown in FIG. 2, the electronic device 100 is connected to a commercial power supply 41. A switch 42 is provided between the electronic device 100 and the commercial power supply 41. The commercial power supply 41 is managed by, for example, an electric power company and supplies power to a general household. The switch 42 is provided on a home wall or the like, and switches whether to supply power from the commercial power supply 41 to the electronic device 100.

  For example, when the user performs an operation to turn on the switch 42, power is supplied from the commercial power supply 41 to the electronic device 100. Thereby, the illuminating device 110 in the electronic device 100 is turned on. On the other hand, when the user performs an operation to turn off the switch 42, the power supply from the commercial power supply 41 to the electronic device 100 is stopped. Thereby, the illumination device 110 in the electronic device 100 is turned off.

  2, the illumination device 110 of the electronic device 100 includes a power supply circuit 111, an illumination unit 112, a communication circuit 113, a RAM 114, a nonvolatile memory 115, a power supply monitoring circuit 116, and a control unit. 117. Although not illustrated in FIG. 2, the illumination device 110 may include a receiver that receives a signal transmitted from the remote controller. Such a receiver receives, for example, a signal indicating that the illuminance or color of illumination light in the illumination device 110 is changed.

  The power supply circuit 111 generates power required for the operation of the lighting device 110 from the power supplied from the commercial power supply 41, and generates the generated power for each unit (the lighting unit 112, the communication circuit 113, the RAM 114, and the nonvolatile memory in the lighting device 110). 115, a power supply monitoring circuit 116, and a control unit 117). The illumination unit 112 is an LED (Light Emitting Diode), a light bulb, or the like, and illuminates a room or the like. The communication circuit 113 is connected to the communication adapter 120 (a communication circuit 123 described later) and communicates with the communication adapter 120.

  The RAM 114 is a volatile storage device and stores, for example, state information regarding the state of the lighting device 110. That is, the RAM 114 can store state information when power is supplied from the power supply circuit 111, but loses the stored state information when power supply is stopped. In addition, RAM114 which concerns on embodiment shall memorize | store the illumination setting information regarding the illumination intensity and color of the light illuminated by the illumination part 112 as an example of state information.

  The nonvolatile memory 115 is a nonvolatile storage device and stores various types of information. In other words, the nonvolatile memory 115 can store various information regardless of whether or not power is supplied from the power supply circuit 111. As will be described later, the non-volatile memory 115 stores the illumination setting information stored in the RAM 114 by the save unit 119.

  The power supply monitoring circuit 116 monitors whether the switch 42 is on or off. In other words, the power supply monitoring circuit 116 monitors whether power is supplied from the commercial power supply 41 to the lighting device 110. The power supply monitoring circuit 116 notifies the control unit 117 of the detection result when it is detected that the switch 42 has been turned off from on or when the switch 42 has been turned on from off.

  The control unit 117 controls the entire illumination device 110. For example, the control unit 117 is realized by a CPU (Central Processing Unit). Then, the control unit 117 uses the RAM 114 as a work area and executes a program stored in a storage device (for example, a non-volatile memory 115 or a ROM (Read Only Memory)) inside the lighting device 110, so that the lighting device 110. Control the whole. 2 illustrates an example in which the control unit 117 is realized by the CPU, the control unit 117 may be realized by, for example, an MPU (Micro Processing Unit) or the like, or an ASIC (Application Specific Integrated Circuit). And an integrated circuit such as an FPGA (Field Programmable Gate Array).

  Here, when the power supply from the commercial power supply 41 to the electronic device 100 is stopped, the control unit 117 according to the embodiment executes and controls predetermined processing that is determined in advance. Specifically, when the switch 42 is turned off, the control unit 117 saves the illumination setting information regarding the illuminance and color of the illumination light from the RAM 114 to the nonvolatile memory 115. As a result, when the switch 42 is subsequently turned on, the control unit 117 restores the illuminance and the color before the switch 42 is turned off and causes the illumination unit 112 to illuminate.

  This point will be described with reference to FIG. FIG. 3 is a diagram illustrating a configuration example of the control unit 117 included in the illumination device 110 according to the embodiment. As illustrated in FIG. 3, the control unit 117 includes an illumination control unit 118 and a retracting unit 119.

  The illumination control unit 118 controls the illumination unit 112. Specifically, the illumination control unit 118 reads the illumination setting information from the nonvolatile memory 115 when notified from the power supply monitoring circuit 116 that the switch 42 is turned on, and the illuminance indicated by the read illumination setting information The illumination unit 112 is illuminated by the color.

  Moreover, the illumination control part 118 illuminates the illumination part 112 with the illumination intensity and color after a change, when operation which changes the illumination intensity and color of the illumination light in the illumination part 112 by a user is performed. At this time, the illumination control unit 118 writes the illumination setting information indicating the changed illuminance and color in the RAM 114. That is, the illumination control unit 118 holds the illumination setting information regarding the illuminance and color of the light currently illuminated by the illumination unit 112 in the RAM 114.

  The saving unit 119 saves the illumination setting information stored in the RAM 114 in the nonvolatile memory 115 when notified from the power monitoring circuit 116 that the switch 42 is turned off. Specifically, when the switch 42 is turned off, the power supply from the commercial power supply 41 to the lighting device 110 is stopped. However, even if the supply power from the commercial power supply 41 is stopped at the moment when the switch 42 is turned off, the power supply circuit 111 supplies power to each unit such as the control unit 117 for a predetermined time. Therefore, the saving unit 119 performs a saving process of the illumination setting information at a predetermined time when power is supplied from the power supply circuit 111 when the switch 42 is turned off. At this time, if the lighting setting information is already stored in the nonvolatile memory 115, the saving unit 119 overwrites the lighting setting information with the lighting setting information stored in the RAM 114. Thereby, the saving unit 119 can save the illumination setting information in the RAM 114 that disappears when the power supply from the power supply circuit 111 is stopped to the nonvolatile memory 115. As described above, when the power supply circuit 111 is turned off, the control state is stored in the nonvolatile memory 115. Therefore, it is not necessary to sequentially store the control state, and the control is not complicated at the time of control. That is, since it is not necessary to store in the non-volatile memory 115 at the time of control, the power supply and control can be used for lighting control. Furthermore, the final control state can be reliably stored.

  Returning to the description of FIG. 2, the communication adapter 120 of the electronic device 100 relays a control command and a response transmitted and received between the lighting device 110 and the access point 30 as described above. As illustrated in FIG. 2, the communication adapter 120 includes a power supply circuit 121, a wireless communication circuit 122, a communication circuit 123, and a control unit 124.

  The power supply circuit 121 generates power required for the operation of the communication adapter 120 from the power supplied from the commercial power supply 41, and generates the generated power for each unit (wireless communication circuit 122, communication circuit 123, control unit 124) in the communication adapter 120. It is the electric power supply part supplied to. The wireless communication circuit 122 performs short-range wireless communication with the access point 30 such as Bluetooth (registered trademark). The communication circuit 123 is connected to the communication circuit 113 of the lighting device 110 and performs communication with the lighting device 110. The wireless communication circuit 122 and the communication circuit 123 as described above function as a communication unit that relays data transmitted and received between the lighting device 110 and the network including the access point 30 and the like. In addition, as illustrated in FIG. 2, the communication adapter 120 according to the embodiment is configured such that power is not supplied to the wireless communication circuit 122 and the communication circuit 123 from the power supply circuit 111 provided in the lighting device 110.

As in the electronic device 100 ₃ shown in FIG. 1, the communication adapter 120 may also be an access point and a wired connection. In this case, the communication adapter 120 includes a wired communication circuit that performs wired communication with the access point instead of the wireless communication circuit 122.

  The control unit 124 controls the entire communication adapter 120. Specifically, the control unit 124 performs a relay process of a control command and a response. The control unit 124 is realized by a CPU, for example. And the control part 124 controls the communication adapter 120 whole by running the program memorize | stored in ROM etc. inside the communication adapter 120 by making RAM etc. which are not shown into a work area. 2 shows an example in which the control unit 124 is realized by the CPU, the control unit 124 may be realized by an MPU or the like, or may be realized by an integrated circuit such as an ASIC or FPGA. Good.

  As described above, in the electronic device 100 according to the embodiment, the power supply circuit 111 is provided in the illumination device 110 and the power supply circuit 121 is also provided in the communication adapter 120. For this reason, in the electronic device 100 according to the embodiment, even when the switch 42 is turned off, the power supplied from the power supply circuit 111 is not consumed by the communication adapter 120, so that sufficient power is supplied to the save unit 119. As a result, it can be prevented that the saving process by the saving unit 119 is not completed.

  This point will be described with reference to FIG. FIG. 4 is a diagram illustrating a time variation example of the power supplied from the power supply circuit 111 according to the embodiment. Note that the power fluctuation W10 indicated by the one-dot chain line in FIG. A power fluctuation W20 indicated by a solid line in FIG. 4 indicates an example of power supplied from the power supply circuit 111 according to the embodiment.

  First, a case where the power supply circuit 121 is not provided in the communication adapter 120 will be described. In this case, the wireless communication circuit 122, the communication circuit 123, and the control unit 124 inside the communication adapter 120 are connected to the power supply circuit 111 provided in the lighting device 110 and operate by the power supplied from the power supply circuit 111. That is, when the power supply circuit 121 is not provided in the communication adapter 120, the power supply circuit 111 is connected to each part (control unit 124, etc.) in the communication adapter 120 in addition to each part (control unit 117, etc.) in the lighting device 110. Even power will be supplied.

  For this reason, as shown in the power fluctuation W10 in FIG. 4, when the power supplied from the commercial power supply 41 is stopped by turning off the switch 42, the power supplied from the power supply circuit 111 is supplied to the communication adapter 120. Since it is also consumed, it drops rapidly. This may lead to a situation where the power supply from the power supply circuit 111 to the control unit 117 is stopped before the above-described saving process by the saving unit 119 of the control unit 117 is completed. When such a situation occurs, the illumination setting information is not saved in the nonvolatile memory 115, and thus the illumination control unit 118 cannot restore the illuminance and color to illuminate the illumination unit 112. As described above, since a general electronic device corresponding to a home network system has a communication function, when the power is turned off, the processing to be executed when the power is turned off is not always completed. .

  On the other hand, the communication adapter 120 according to the embodiment is provided with a dedicated power supply circuit 121. In this case, the power supply circuit 111 does not supply power to each unit (such as the control unit 124) in the communication adapter 120, and supplies power only to each unit (such as the control unit 117) in the illumination device 110. For this reason, as shown in the power fluctuation W20 of FIG. 4, when the power supplied from the commercial power supply 41 is stopped by turning off the switch 42, the power supplied from the power supply circuit 111 is supplied to the communication adapter 120. Since it is not consumed, it falls more slowly than the power fluctuation W10. That is, in the electronic device 100 according to the embodiment, it is possible to prevent a situation where the power supply from the power supply circuit 111 to the control unit 117 is stopped before the saving process by the saving unit 119 of the control unit 117 is completed. As a result, the illumination control unit 118 according to the embodiment can restore the illuminance and color to illuminate the illumination unit 112. Moreover, in this embodiment, you may make it comprise the communication adapter 120 retrofit with respect to the illuminating device 110. FIG. In this case, the power supply of the illumination device 110 can be optimized regardless of the power consumption of the communication adapter 120. That is, even when the communication adapter 120 is not attached to the lighting device 110 or when it is attached later, it can be stably operated. For this reason, when the power supply to the illumination device 110 is turned off, the control state can be reliably stored.

[Processing procedure of home appliance control system]
Next, a processing procedure by the home appliance control system 1 will be described with reference to FIG. FIG. 5 is a flowchart illustrating a processing procedure performed by the home appliance control system 1 according to the embodiment. In the example of FIG. 5, it is assumed that the initial state of the electronic device 100 is power off.

  As shown in FIG. 5, the power supply monitoring circuit 116 of the lighting device 110 monitors whether or not the switch 42 is turned on (step S101). When the power supply monitoring circuit 116 does not detect that the switch 42 is turned on (No in step S101), the power supply monitoring circuit 116 monitors until the switch 42 is turned on.

  On the other hand, when the power supply monitoring circuit 116 detects that the switch 42 is turned on (step S101 Yes), the illumination control unit 118 reads the illumination setting information from the nonvolatile memory 115 (step S102). And the illumination control part 118 makes the illumination part 112 illuminate with the illumination intensity and color which the illumination setting information read from the non-volatile memory 115 shows (step S103).

  Subsequently, the illumination control unit 118 determines whether or not an operation for changing the illumination setting information has been received (step S104). For example, the illumination control unit 118 determines whether or not an illuminance or color change operation has been performed by the user using a remote controller or the like. And when the illumination control part 118 receives the change operation of illumination setting information (step S104 Yes), the illumination part 112 is made to illuminate with the illumination intensity and color which the illumination setting information after a change shows (step S105). Moreover, the illumination control part 118 writes the illumination setting information after a change in RAM114 (step S106). In addition, the illumination control part 118 does not perform the process in step S105 and S106, when the change operation of illumination setting information is not received (step S104 No).

  Subsequently, the power monitoring circuit 116 monitors whether or not the switch 42 is turned off (step S107). When the power supply monitoring circuit 116 detects that the switch 42 is turned off (Yes at Step S107), the saving unit 119 saves the illumination setting information stored in the RAM 114 in the nonvolatile memory 115 (Step S107). S108). And when predetermined time passes, since the electric power supply from the power supply circuit 111 stops, the illumination part 112 turns off.

  Note that while the power supply monitoring circuit 116 does not detect that the switch 42 is turned off (No in step S107), the electronic device 100 repeatedly performs the processes in steps S104 to S107.
