First Embodiment
<Overall configuration of network system 1>

First, the overall configuration of the network system 1 according to the present embodiment will be described with reference to FIG. 1. The network system 1 according to the present embodiment mainly includes a first server 100A, a second server 100B, a sensor device 200A, electrical devices 200B and 200C, and a communication terminal 300.

The first server 100A is used in various facilities. It is preferable that the first server 100A is prepared in each of the multiple facilities. Each of the first servers 100A may be installed inside the facility or outside the facility. The first server 100A is connected to various sensor devices 200A such as reclining beds, intercoms, room thermometers, various sensors for acquiring biometric information of patients and guests in the rooms, lights, showers, toilet facilities, and floor heating, which are arranged in each room in the facility. In this embodiment, the first server 100A used in a nursing home for the elderly will be described.

And particularly in this embodiment, the sensor device 200A measures data necessary to detect that a subject in a facility room has woken up or gone to sleep. The sensor device 200A may determine that the subject has woken up or gone to sleep, or the first server 100A may determine that the subject has woken up or gone to sleep based on measurement data such as movement and pressure measured by the sensor device 200A. In the following, for the sake of explanation, it is assumed that the sensor device 200A is a reclining bed having a pressure sensor and a computer, and when the computer detects pressure equal to or greater than a predetermined value, it determines that the subject is asleep if the subject is lying down, and determines that the subject is awake if it does not detect pressure equal to or greater than the predetermined value.

The second server 100B is composed of, for example, multiple databases, computing devices, and communication devices on the cloud. The second server 100B is connected to multiple electrical appliances 200B, 200C, such as air conditioners and refrigerators, via various networks, such as the Internet and a carrier network. In this embodiment, the second server 100B is also connected to the first server 100A.

The electrical devices 200B and 200C may be home appliances such as air conditioners, refrigerators, air purifiers, microwave ovens, washing machines, air purifiers, humidifiers, dehumidifiers, automatic cooking pots, rice cookers, lighting, and vacuum cleaners; AV (audio-visual) devices such as televisions, personal computers, hard disk recorders, projectors, music players, game consoles, and speakers; HEMS equipment such as solar power generation systems, battery systems, hot water supply systems, and underfloor heating; and residential equipment such as built-in lighting, intercoms, electric locks, hot water heaters, and warm water washing toilet seat controllers.

Note that electrical device 200B and electrical device 200C may be the same type of device or different types of devices. Furthermore, sensor device 200A may also be the same type of device as either electrical device 200B or 200C, as long as it can acquire data related to waking up and going to bed.

The communication terminal 300 is connectable to the first server 100A and is realized by a personal computer, a smartphone, a tablet, a game console, a speaker, a wearable device, or the like.
<Overview of Operation of Network System 1>

Next, an overview of the operation of the network system 1 according to the present embodiment will be described with reference to FIG. 1. In the network system 1 according to the present embodiment, the first server 100A periodically acquires various pieces of information from the sensor device 200A. Alternatively, the sensor device 200A pushes information to the first server 100A. The second server 100B also acquires various pieces of information from the electrical device 200B and the electrical device 200C via the Internet or the like. As shown in FIG. 2, the first server 100A acquires various pieces of information on the sensor device 200A in the facility and displays them on the communication terminal 300. The first server 100A also acquires various pieces of information on the electrical device 200B from the second server 100B, and as shown in FIG. 2, displays the information on the electrical device 200B on the communication terminal 300. It is preferable that the first server 100A display on the communication terminal 300 a screen that combines information on the sensor device 200A, information on the electrical device 200B, and information on facility users, etc. This allows the communication terminal 300 to present both information on the sensor device 200A that the first server 100A of the facility can directly obtain, and information on the electrical device 200B from the second server 100B that the first server 100A cannot directly obtain.

In particular, in this embodiment, when it is detected that a subject such as a facility user has woken up based on the measurement data of the sensor device 200A, the electric device 200C in the house of the subject's family who is located away from the facility outputs a voice message to that effect, and the electric device 200B in the subject's room outputs a voice message spoken by the family member. The specific configuration of the network system 1 for realizing such functions will be described in detail below.
<Configuration of First Server 100A>

First, one aspect of the configuration of the first server 100A constituting the network system 1 according to the present embodiment will be described. Referring to FIG. 3, the first server 100A includes, as main components, a CPU (Central Processing Unit) 110, a memory 120, an operation unit 140, and a communication interface 160.

The CPU 110 controls each part of the first server 100A by executing a program stored in the memory 120. For example, the CPU 110 executes a program stored in the memory 120 and performs various processes described below by referring to various data.

Memory 120 is realized by various types of RAM (Random Access Memory), various types of ROM (Read-Only Memory), etc., and may be included in first server 100A, may be detachable from various interfaces of first server 100A, or may be a recording medium of another device accessible from first server 100A. Memory 120 stores programs executed by CPU 110, data generated by execution of programs by CPU 110, input data, and other databases used for the services according to this embodiment.

For example, memory 120 stores facility information data as shown in FIG. 4. The facility information data stores a facility ID, sensor information, main unit information, resident information, personal information, information about the facility's own system, information about other sensors, information about other systems, etc.

The facility ID is identification information for identifying the facility or business and is used when accessing the second server 100B.

Sensor information is data stored as history, and is information obtained directly from the sensor device 200A periodically or at any time, or information from various sensors obtained from the second server 100B.

The main unit information is data stored as history, and is information on the operating status and operation details of the electrical device 200B that is periodically obtained from the second server 100B.

The resident's personal information is information to be displayed on the screen of the communication terminal 300. Note that this information is not provided to the second server 100B.

The company's system information includes information for operating the company's own call system managed by the first server 100A.

The information from other sensors includes information read from various sensors made by other companies that are managed by the first server 100A. For example, it includes information about beds, information about people's movements, information about door opening and closing, lighting information, and illuminance information.

The information from other systems includes information obtained from other companies' systems connected to the first server 100A via the Internet. For example, it includes weather information, location information, time of year information, and outside temperature information.

The memory 120 also stores first correspondence data 121 as shown in FIG. 5. The first correspondence data 121 stores, for each subject residing in the facility, the correspondence between the subject's identification information, the subject's name, room identification information, the communication address of a sensor device 200A placed in the subject's room, identification information of an electrical device 200B placed in the subject's room, identification information of the subject's family, and identification information of an electrical device 200C placed in the subject's family's home.

Returning to FIG. 3, the operation unit 140 accepts commands from a service administrator or the like and inputs the commands to the CPU 110.

The communication interface 160 transmits data from the CPU 110 to other devices such as the sensor device 200A, the electrical device 200B, the communication terminal 300, and a server via the Internet, a carrier network, a router, etc. Conversely, the communication interface 160 receives data from other devices via the Internet, a carrier network, a router, etc., and passes the data to the CPU 110.
<Information Processing of the First Server 100A>

Next, information processing in the first server 100A will be described with reference to FIG. 6. The CPU 110 of the first server 100A in this embodiment executes the following processing in accordance with the program in the memory 120.

First, the CPU 110 receives data from the sensor device 200A via the communication interface 160 (step S102).

When the CPU 110 acquires information from the sensor device 200A that the subject has woken up and the time that the subject woke up based on the data (YES in step S104), it refers to the first correspondence data 121 to identify the electrical device 200C of the subject or his/her family that corresponds to the sensor device 200A (step S106).

The CPU 110 transmits information to the second server 100B via the communication interface 160, such as information that the subject has woken up and information for identifying the electrical device 200C (step S108).

When the CPU 110 acquires information from the sensor device 200A that the subject has gone to sleep and the time the subject went to sleep based on the received data (YES in step S110), it refers to the first correspondence data 121 to identify the electrical device 200C of the subject or his/her family that corresponds to the sensor device 200A (step S112).

The CPU 110 transmits information that the subject has gone to sleep, information for identifying the electrical device 200C, and the like to the second server 100B via the communication interface 160 (step S114).

If CPU 110 has received other data (NO in step S110), it executes other processing (step S120).
<Configuration of second server 100B>

Next, one aspect of the configuration of the second server 100B constituting the network system 1 according to the present embodiment will be described. However, since the basic configuration of the second server 100B is similar to that of the first server 100A shown in FIG. 3, the description will not be repeated here. Below, the stored data and information processing that differ from that of the first server 100A will be described.

The memory 120 of the second server 100B stores device information data as shown in FIG. 7. The device information data stores a list of facility IDs, the correspondence between facility IDs and device IDs, sensor information, main unit information, etc.

The list of facility IDs includes a list of information for identifying the facility as a user of the first server 100A when the first server 100A accesses it.

The correspondence between facility IDs and device IDs includes information for identifying the electrical device 200B associated with each facility. The second server 100B identifies the target electrical device 200B for each facility based on this correspondence.

The sensor information is cache data that temporarily stores the measurement values of each sensor acquired from the multiple electrical devices 200B periodically or at an instruction from the system of the first server 100A. More specifically, the sensor information is information that the second server 100B periodically or at an arbitrary timing provides the acquired sensor values of the electrical devices 200B to the first server 100A periodically or at an arbitrary timing.

The main body information is cache data that temporarily stores operating states and operation commands obtained from multiple electrical devices 200B periodically or at the command of the first server 100A system.

Furthermore, memory 120 stores second correspondence data 122 as shown in Fig. 8. First correspondence data 121 stores the correspondence between identification information of electric device 200B placed in the subject's room, its communication address, and identification information of electric device 200C placed in the subject's family's house, its communication address.
<Information Processing of the Second Server 100B>

Next, information processing in the second server 100B will be described with reference to FIG. 9. The CPU 110 of the second server 100B in this embodiment executes the following processing in accordance with the program in the memory 120.

First, the CPU 110 receives data via the communication interface 160 (step S152).

When the CPU 110 receives information from the first server 100A based on the data indicating that the subject has woken up (YES in step S154), it turns on the message exchange flag in the memory 156 (step S156).

The CPU 110 calculates the time limit for prompting the user to input a message, a predetermined time after the user wakes up, for example, one hour, and stores the time limit in the memory 120 in association with the identification information of the electrical device 200C (step S158).

The CPU 110 refers to the second correspondence data 122 and identifies the communication address of the electrical device 200C based on the identification information of the electrical device 200C of the subject family member obtained from the first server 100A (step S160).

The CPU 110 transmits, via the communication interface 160, to the electrical device 200C of the family of the subject, information indicating that the subject has woken up, an instruction to output a voice prompting the subject to input a message, and a deadline for the period during which the message should be prompted to be input (step S162).

On the other hand, if the CPU 110 obtains information based on the received data that the target person has gone to sleep (YES in step S164), it turns off the message exchange flag (step S166).

The CPU 110 refers to the second correspondence data 122 and identifies the communication address of the electrical device 200C based on the identification information of the electrical device 200C of the subject family member (step S168).

The CPU 110 transmits, via the communication interface 160, to the electrical device 200C of the family member of the subject, information indicating that the subject has gone to bed and an instruction to output a voice to end the message exchange (step S170).

When the CPU 110 acquires voice data of a message from an electric device 200C of the target person's family based on the received data (YES in step S172), the CPU 110 refers to the second correspondence data 122 to identify the communication address of the corresponding electric device 200B of the target person (step S174). The CPU 110 transmits the voice data of the message to the corresponding electric device 200B of the target person via the communication interface 160 (step S176).

When the CPU 110 acquires voice data of a message from the target person's electric device 200B based on the received data (YES in step S182), it refers to the second correspondence data 122 to identify the communication address of the target person's family member's electric device 200C (step S184). The CPU 110 transmits the voice data of the message to the target person's family member's electric device 200C via the communication interface 160 (step S186).

If CPU 110 has received other data (NO in step S182), it executes other processes (step S190).
<Configuration of the sensor device 200A>

Next, referring to FIG. 10, we will explain one aspect of the configuration of the sensor device 200A placed in the facility.

The main components of the sensor device 200A in this embodiment are a CPU 210, a memory 220, an operation unit 240, a communication interface 260, and a sensor 295.

The CPU 210 controls each part of the sensor device 200A by executing programs stored in the memory 220 or an external storage medium.

The memory 220 is realized by various RAMs, various ROMs, etc., and stores information necessary to use various services, such as programs executed by the CPU 210, data generated by execution of the programs by the CPU 210, data input via the operation unit 240, data received from the remote control, and data received from the first server 100A via a router or the Internet.

The operation unit 240 is realized by buttons, a touch panel, etc., and receives commands from the user and inputs the commands to the CPU 210.

The communication interface 260 is realized by an antenna for wireless communication, a connector for wired communication, and the like. By using the communication interface 260, the CPU 210 exchanges various data with the first server 100A, other electrical devices 200B, and communication terminals 300 via a router, the Internet, and the like. For example, the CPU 210 provides operation details and environmental information to the first server 100A, and receives operation commands from the first server 100A, via the communication interface 260.

The sensor 295 measures data for detecting that the subject has woken up or gone to sleep, such as pressure values, temperature, posture, acceleration, and movement, and inputs the data to the CPU 210. This allows the CPU 210 of the sensor device 200A or the CPU 110 of the first server 100A to determine that the subject in the room of the sensor device 200A has woken up or gone to sleep.
<Configuration of Electric Devices 200B and 200C>

Next, referring to FIG. 11, one embodiment of the configuration of electrical device 200B and electrical device 200C arranged in the facility will be described. Note that, since electrical device 200B and electrical device 200C have the same main configuration, the following description will focus on electrical device 200, which includes both of them.

The electrical device 200 in this embodiment includes, as main components, a CPU 210, a memory 220, a display 230, an operation unit 240, a communication interface 260, a speaker 270, a microphone 280, a device drive unit 290, and a human presence sensor 291.

The CPU 210 controls each part of the electrical device 200 by executing programs stored in the memory 220 or an external storage medium.

The memory 220 is realized by various RAMs, various ROMs, etc., and stores information necessary for using various services, such as programs executed by the CPU 210, data generated by execution of the programs by the CPU 210, data input via the operation unit 240, data received from the remote control, data received from the first server 100A and the second server 100B via a router or the Internet, and addresses of management servers corresponding to the electrical devices 200B and 200C.

The display 230 outputs characters, images, etc. based on signals from the CPU 210. Note that the display 230 may simply be an LED light, etc.

The operation unit 240 is realized by a button, a touch panel, etc., and receives commands from a user and inputs the commands to the CPU 210. The display 230 and the operation unit 240 may form a touch panel 250.

The communication interface 260 is realized by an antenna for wireless communication, a connector for wired communication, and the like. By using the communication interface 260, the CPU 210 exchanges various data with the first server 100A, the second server 100B, other electrical devices 200B, 200C, and the communication terminal 300 via a router, the Internet, or the like. For example, the CPU 210 provides operation details and environmental information to the first server 100A and the second server 100B, and receives operation commands from the first server 100A and the second server 100B, via the communication interface 260.

The speaker 270 outputs voice messages and the like based on voice data from the CPU 210. The microphone 280 acquires the user's voice and inputs the voice data to the CPU 210.

The device driving unit 290 controls each part (motor, heater, sensor, antenna, etc.) of the electrical devices 200B, 200C based on signals from the CPU 210. The device driving unit 290 may be, for example, a compressor, fan, or damper in a refrigerator, a compressor or fan in an air conditioner, a reclining motor or heater in a bed, an antenna or rotating table for cooking in a microwave oven, or a receiving antenna or tuner in a television. Note that there are electrical devices that do not particularly require a device driving unit 290, such as an intercom or nurse call system.

The human presence sensor 291 detects people in the vicinity and inputs the detection results to the CPU 210.

In this embodiment, the CPU 210 receives information indicating that the subject has woken up, an instruction to output a sound prompting the subject to input a message, and a deadline for the period during which the subject is to be prompted to input a message from the second server 100B via the communication interface 260. When the human presence sensor 291 detects a person or when various operations are accepted, the CPU 210 causes the speaker 270 to output a message indicating that the subject has woken up and also outputs a message prompting the subject to input a message. For example, a sound saying "It looks like Mommy has woken up. Please leave a message for Mommy." In this embodiment, when the CPU 210 outputs wake-up information after the deadline for the message prompt has passed, it outputs only the wake-up information and does not output a message prompting the subject to input a message.

When the CPU 210 receives a message from a family member via the microphone 280, it transmits the voice to the second server 100B via the communication interface 260. When the target person's electric device 200B detects the target person or is operated based on the data from the second server 100B, it outputs the message as voice and notifies the second server 100B that the voice has been output. Upon receiving the notification, the second server 100B transmits to the family member's electric device 200C that a message has been output on the other party's electric device 200B. The CPU 210 of the electric device 200C outputs from the display 230 or speaker 270 that a message has been output on the target person's electric device 200B based on the information from the second server 100B.

Then, when the CPU 210 of the target person's electric device 200B receives a message from the second server 100B, it outputs the message from the speaker 270, accepts a new message via the microphone 280, and transmits the voice data or text data of the new message to the second server 100B. Then, when the CPU 210 of the family member's electric device 200C receives a message from the second server 100B, it outputs the message from the speaker 270, accepts a new message via the microphone 280, and transmits the voice data or text data of the new message to the second server 100B. In this way, the second server 100B alternates between transmitting messages from the target person and messages from the family member.

Then, when the CPU 210 receives information from the second server 100B via the communication interface 260 indicating that the other party has gone to sleep or an instruction to output a sound to end the message exchange, the CPU 210 outputs the information from the speaker 270 and ends the acceptance and transmission of the message.
<Configuration of communication terminal 300>

The display 330 displays images and text based on data from the CPU 310. The operation unit 340 is composed of a pointing device, switches, etc., and inputs various commands from the user to the CPU 310. The communication terminal 300 may also have a touch panel 350 that includes the display 330 and the operation unit 340.

The communication interface 360 transmits and receives data to and from other devices such as the first server 100A and the electrical device 200 via the Internet, a carrier network, a router, etc. For example, the CPU 310 exchanges various pieces of information about the user with the first server 100A via the communication interface 360 in accordance with a program. The CPU 310 can receive various services by providing the various pieces of information to other application programs.

The speaker 370 outputs voice messages and the like based on the voice data from the CPU 310. The microphone 380 acquires the user's voice and inputs the voice data to the CPU 310.

In this embodiment, the CPU 310 exchanges data with the first server 100A via the communication interface 360 based on instructions from the facility manager or the subject, in accordance with the program in the memory 320. For example, the CPU 310 acquires information on the sensor device 200A and information on the electric device 200B via the first server 100A by using the communication interface 360, and displays a viewing screen or an operation screen on the display 330. The CPU 310 also accepts an operation command for the sensor device 200A or the electric device 200B from the facility manager via the operation unit 340, and transmits the operation command to the first server 100A via the communication interface 360.

When the second server acquires information that a person has woken up via the first server, the second server causes the second home appliance to output the information by voice, and causes the first home appliance to output a message input to the second home appliance by voice without going through the first server.

Preferably, the second home appliance outputs information when it detects a person or receives an operation, and outputs a voice prompting the user to enter a message.

Preferably, the second server does not output audio prompting the user to enter a message after a predetermined time has elapsed since waking up.

Preferably, the first home appliance outputs a message input to the first home appliance by voice when a person is detected or an operation is received. The second server causes the second home appliance to output information that the first home appliance has output a message.

Preferably, the second server repeats a step of causing the second home appliance to output a message input to the first home appliance by voice without going through the first server, and a step of causing the first home appliance to output a message input to the second home appliance by voice without going through the first server.

Preferably, when the second server detects via the first server information that a person has gone to bed, it causes the second home appliance to output the information as audio and terminates the acceptance of messages by the second home appliance and the first home appliance.

In the above embodiment, a server is provided that includes a communication interface for communicating with a first server, a first home appliance, and a second home appliance, and a processor that, when information that a person has woken up is acquired via the first server by using the communication interface, causes the second home appliance to output the information by voice, and causes the first home appliance to output a message input to the second home appliance by voice without going through the first server.

The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is indicated by the claims, not by the above description, and is intended to include all modifications within the meaning and scope of the claims.
