[0007] [Figure 1] This is a schematic diagram of the control system according to this embodiment. [Figure 2] This figure shows a locking and unlocking device provided in a door or window according to this embodiment. [Figure 3] This is a perspective view of the locking / unlocking device according to this embodiment. [Figure 4] This is a schematic diagram of the locking and unlocking device according to this embodiment. [Figure 5] This is a schematic diagram of the control device according to this embodiment. [Figure 6] This figure shows an example of building information according to this embodiment. [Figure 7] This is a flowchart illustrating the operation of the control system according to this embodiment. [Modes for carrying out the invention]

[0008] As shown in Figure 1, the control system 1 according to this embodiment includes a communication device 10, a plurality of locking / unlocking devices 20 (locking / unlocking devices 20-1 to 20-n), and a control device 30. Based on information received from the plurality of locking / unlocking devices 20, the control system 1 controls a plurality of types of electric devices 200-1 to 200-m installed in the user's building 100 via a communication network NW.

[0009] n and m are integers greater than or equal to 2. The symbols following the hyphen distinguish multiple components of the same type from each other. If multiple components of the same type are not distinguishable from each other, the symbols following the hyphen may be omitted. Building 100 is a residence such as an apartment building or a detached house, a hospital, or a facility. In this embodiment, the case where building 100 is a user's residence will be described. In the following description, multiple types of electric devices 200-1 to 200-m may be referred to as multiple types of electric devices 200.

[0010] The communication device 10 is connected to the control device 30 via a communication network NW. The communication device 10 is connected to the locking / unlocking devices 20-1 to 20-n and several types of electric devices 200-1 to 200-m. The communication device 10 relays information between the control device 30 and the locking / unlocking devices 20-1 to 20-n. The communication device 10 relays information between the control device 30 and several types of electric devices 200-1 to 200-m. The communication device 10 includes, for example, a router and a gateway.

[0011] The communication network NW may be a wireless communication transmission path (e.g., a wireless LAN), or a combination of a wireless communication transmission path and a wired communication transmission path. The communication network NW may be any of the following: a mobile communication network such as a mobile phone network, a wireless packet communication network, the Internet, or a dedicated line, or a combination thereof. For example, the communication network NW may use a Low-power Wide-area Network (LPWAN), or it may use short-range wireless communication standards such as ZigBee®, Wi-Fi®, or BLE.

[0012] Multiple locking / unlocking devices 20-1 to 20-n are installed in the building 100. As shown in Figure 2, the locking / unlocking devices 20 lock and unlock the fixtures 110 installed in the openings of the building 100. For example, the locking / unlocking device 20 is a crescent lock. The fixtures 110 are, for example, sliding windows. However, they are not limited to this, and the fixtures 110 may be interior doors, etc. The locking / unlocking devices 20 are installed in the fixtures 110 of each room, such as the kitchen, living room, children's room, and bedroom. The locking / unlocking devices 20 may also be installed in fixtures 110 installed in the toilet, bathroom, washroom, entrance, etc.

[0013] The locking / unlocking device 20 is connected to the communication network NW via the communication device 10. The locking / unlocking device 20 transmits information to the control device 30 via the communication network NW.

[0014] As shown in FIG. 3, the locking and unlocking device 20 includes a base 21, a handle portion 22, and a crescent fitting 23.

[0015] The base 21 is fixed to one frame of the fitting 110. The handle portion 22 is a lever operated by a user. The handle portion 22 is provided rotatably with respect to the base 21. The crescent fitting 23 rotates in conjunction with the handle portion 22 and engages with a crescent receiving fitting (not shown) fixed to the other frame of the fitting.

[0016] When the handle portion 22 rotates, the crescent fitting 23 engages with the crescent receiving fitting. When the crescent fitting 23 engages with the crescent receiving fitting, the fitting 110 is locked. The state in which the crescent fitting 23 engages with the crescent receiving fitting may be referred to as a locked state. By rotating the handle portion 22 from the locked state, the crescent fitting 23 is disengaged from the crescent receiving fitting, and thus the fitting is unlocked. The state in which the crescent fitting 23 is not engaged with the crescent receiving fitting may be referred to as an unlocked state.

[0017] As shown in FIG. 4, the locking and unlocking device 20 includes a power supply unit 24, a locking and unlocking detection unit 25, a living environment detection unit 26, an output unit 27, and a light emitting diode 28.

[0018] The power supply unit 24 supplies power to each of the locking and unlocking detection unit 25, the living environment detection unit 26, the output unit 27, and the light emitting diode 28. The power supply unit 24 includes, for example, a primary battery or a secondary battery. The power supply unit 24 may generate power by sunlight. The power supply unit 24 may have a secondary battery and store the power generated by sunlight in the secondary battery.

[0019] The locking / unlocking detection unit 25 detects information (hereinafter referred to as "state information") that can distinguish whether the locking / unlocking device 20, which is a lock for locking the fitting 110, is in the locked state or the unlocked state. As an example, the locking / unlocking detection unit 25 includes an acceleration sensor. The locking / unlocking detection unit 25 can detect the rotation angle of the handle portion 22 by the acceleration sensor. The locking / unlocking detection unit 25 can detect whether the locking / unlocking device 20 is in the locked state or the unlocked state based on the rotation angle of the handle portion 22. The state information may be information indicating whether the locking / unlocking device 20 is in the locked state or the unlocked state. The state information may be the detection result of the acceleration sensor.

[0020] The locking / unlocking detection unit 25 is not limited to the acceleration sensor, and other sensors may be used to detect the state information. The locking / unlocking detection unit 25 has a magnetic field sensor and may detect whether the locking / unlocking device 20 is in the locked state or the unlocked state by detecting the magnetic field of a magnet attached to the fitting 110 with the magnetic field sensor. The locking / unlocking detection unit 25 only needs to be able to detect the state information using known techniques, and the method is not particularly limited. The locking / unlocking detection unit 25 is, for example, housed in the handle portion 22.

[0021] The living environment detection unit 26 detects living environment information indicating the living environment inside the building 100. The living environment information is, for example, at least any one of temperature, humidity, illuminance, carbon dioxide concentration, and odor concentration. The odor concentration, for example, refers to the dilution multiple when the odor is diluted with odorless clean air until the odor disappears. The odor concentration may be an odor index, which is a value obtained by multiplying the common logarithm of the dilution multiple by ten. The living environment detection unit 26 may have a plurality of sensors or only one sensor among a temperature / humidity sensor, an illuminance sensor, a carbon dioxide sensor, and an odor sensor. When the living environment detection unit 26 has a plurality of sensors, the plurality of sensors may be mounted on one substrate. The living environment detection unit 26 is, for example, housed in the handle portion 22.

[0022] The output unit 27 outputs the living environment information detected by the living environment detection unit 26. The output unit 27 may, for example, output the living environment information detected by the living environment detection unit 26 to an external device, which is an externally installed device, via wired or wireless connection. For example, the output unit 27 may have a wireless communication function and communicate with the external device via a wireless communication network. The output unit 27 is housed, for example, in the handle unit 22.

[0023] As an example, the output unit 27 outputs living environment information to a control device 30, which is an example of an external device, via the communication device 10. However, it is not limited to this, and the output unit 27 may also wirelessly output living environment information to a communication terminal 300 held by the user, which is another example of an external device. When transmitting living environment information to an external device, the output unit 27 may add identification information of the locking / unlocking device 20 to the living environment information. The output unit 27 may also output living environment information to a display device. This display device may be provided on the locking / unlocking device 20, or it may be provided on a device other than the locking / unlocking device 20.

[0024] The output unit 27 may further output the status information detected by the lock / unlock detection unit 25. The output unit 27 may also output the status information to an external device via wired or wireless connection, similar to the living environment information. The output unit 27 may also notify the user of the status information detected by the lock / unlock detection unit 25 by using the light emission of the light-emitting diode 28.

[0025] For example, if the output unit 27 detects that the locking / unlocking device 20 is in a locked state, it lights up the light-emitting diode 28 in a first color (for example, green). For example, if the output unit 27 detects that the locking / unlocking device 20 is in an unlocked state, it lights up the light-emitting diode 28 in a second color (for example, red) that is different from the first color.

[0026] The control device 30 is connected to a communication network NW. The control device 30 may be a computer. The control device 30 may be a server device. The control device 30 may be located on the internet or in the cloud. The control device 30 may include at least one physical server. Multiple physical servers configured as the control device 30 are connected to each other via a communication network NW and are therefore able to communicate with each other. The physical server may include at least one virtual server. The virtual server may be a server on a cloud system (cloud server).

[0027] The communication terminal 300 is, for example, a mobile phone, smartphone, tablet, or laptop computer that is portable to the user. The communication terminal 300 may also be a wearable device. The communication terminal 300 is not particularly limited to whether or not it is portable to the user. For example, the communication terminal 300 may be a computer.

[0028] The communication terminal 300 is connected to the control device 30 via a communication network NW. The communication terminal 300 can send and receive information with the control device 30 via the communication network NW. For example, the communication terminal 300 can receive living environment information by communicating with the control device 30 and display the received living environment information on a display screen.

[0029] As shown in Figure 5, the control device 30 includes a storage unit 31 and a control unit 32. These components are realized, for example, by a hardware processor such as a CPU (Central Processing Unit) executing a program (software). Some or all of these components may be realized by hardware (including circuitry) such as an LSI (Large Scale Integrated Circuit), ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), or GPU (Graphics Processing Unit), or by the cooperation of software and hardware. The program may be stored in advance in a storage device such as an HDD (Hard Disk Drive) or flash memory (a storage device with a non-transient storage medium), or it may be stored in a removable storage medium such as a DVD or CD-ROM (a non-transient storage medium) and installed in the storage device when the storage medium is mounted in a drive device. The storage device is composed of, for example, an HDD, flash memory, EEPROM (Electrically Erasable Programmable Read Only Memory), ROM (Read Only Memory), or RAM (Random Access Memory).

[0030] The storage unit 31 stores information indicating, for example, which living space within the building 100 each of the multiple locking / unlocking devices 20 is installed in, as shown in Figure 6. For example, the storage unit 31 stores information (hereinafter referred to as "building information") that associates living space information, which indicates each living space in the building 100, with identification information of the locking / unlocking device 20 installed in that living space, as shown in Figure 6.

[0031] The control unit 32 can control multiple types of electric devices 200 via a communication network NW. The multiple types of electric devices 200 can perform operations that improve the living environment inside the building 100 (hereinafter referred to as "improvement operations"). For example, the multiple types of electric devices 200 include electric window openers, electric shutters, air conditioners, ventilation systems, shielding devices, humidifiers, etc. The shielding devices block light that shines into the building 100 from openings in the building 100. For example, shielding devices include curtains, blinds, roller blinds, etc. By closing the shielding devices, light that shines into the building 100 is blocked.

[0032] The control unit 32 receives living environment information from one or more locking / unlocking devices 20 via a communication network NW. Based on the received living environment information, the control unit 32 performs a determination process to determine whether or not improvements to the living environment are necessary. For example, as part of the determination process, the control unit 32 determines whether or not the received living environment information is within a standard range. If the received living environment information is outside the standard range, the control unit 32 determines that improvements to the living environment are necessary. If the control unit 32 determines that improvements to the living environment are necessary, it controls one or more electric devices 200 from among several types of electric devices 200.

[0033] The control unit 32 can identify living spaces where the living environment information exceeds a standard value, based on the building information illustrated in Figure 6. The storage unit 31 stores information (hereinafter referred to as "electric device information") on which electric devices 200 are installed in each living space within the building 100. The control unit 32 identifies living spaces where the living environment information exceeds a standard value and selects an electric device 200 from among the electric devices 200 installed in the identified living space to bring the living environment information below the standard value. The control unit 32 improves the living environment of the living space by operating the selected electric device 200.

[0034] For example, if the control unit 32 detects that at least one of the carbon dioxide concentration and odor concentration within the building 100 is above a set value as part of the living environment information, it will drive a ventilation device from among the multiple types of electric devices 200 that ventilates the building 100. The ventilation device may be an exhaust fan, an opening / closing device that opens an electric window, or both. If at least one of the carbon dioxide concentration and odor concentration in a certain living space is above a set value, the control unit 32 may control the electric window in that living space to be open, or it may drive a ventilation device installed in that living space, or both.

[0035] The control unit 32 may drive a shielding device from among the multiple types of electric devices 200 if the illuminance inside the building 100 is above a set value as part of the living environment information. For example, if the illuminance in a certain living space is above a set value, the control unit 32 may control the curtains, blinds, roller blinds, etc. of the window on which the locking / unlocking device 20 that measured the illuminance is installed to a closed state.

[0036] For example, if the temperature and humidity inside the building 100 are both above a set value as part of the living environment information, the control unit 32 may control an electric window from among the multiple types of electric devices 200. As an example, if the temperature inside a certain living space is above a set value as part of the living environment information, the control unit 32 may control the electric window installed in that living space to the closed state, and then operate the air conditioner installed in that living space in cooling mode.

[0037] For example, if the humidity in the living space is lower than a first set value according to the living environment information, the control unit 32 may operate a humidifier installed in the living space from among the multiple types of electric devices 200. For example, if the humidity in the living space is higher than a first set value according to the living environment information, the control unit 32 may operate a dehumidifier installed in the living space from among the multiple types of electric devices 200.

[0038] For example, the control unit 32 may determine the heat index (WBGT) based on temperature and humidity information obtained from the living environment detection unit 26. In this case, the control unit 32 determines whether or not the heat index is outside the range of a standard value. If the heat index is outside the range of a standard value, the control unit 32 may operate the air conditioner in cooling mode. When the heat index is outside the range of a standard value, for example, it may be at the warning level or the severe warning level.

[0039] For example, when the control unit 32 receives living environment information from the locking / unlocking device 20-k (1≦k≦n), it performs a determination process. The timing of the determination process may be when the living environment information is received from the locking / unlocking device 20-k, or it may be at a preset time. If the timing of the determination process is a preset time, the control unit 32 performs the determination process based on the latest living environment information.

[0040] If the control unit 32 determines, as a result of the determination process, that improvement of the living environment is necessary, it may extract the identification information of the locking / unlocking device 20-k attached to the living environment information used in the determination process. The control unit 32 reads the living space information associated with the extracted identification information of the locking / unlocking device 20-k from the building information stored in the storage unit 31. The control unit 32 improves the living environment of the living space by controlling the electric device 200 installed in the living space indicated by the read living space information.

[0041] For example, if the room space indicated by the room space information read by the control unit 32 is a living room, and the illuminance is above a set value as part of the determination process, the control unit 32 may reduce the illuminance in the living room by driving the shielding device installed in the living room. Furthermore, if the control unit 32 receives living environment information from the locking / unlocking device 20-k (1≦k≦n), it may identify the room space in which the locking / unlocking device 20-k is installed based on the building information, and then perform the determination process after identification.

[0042] For example, if the control unit 32 determines in the judgment process that improvement of the living environment is necessary, it selects an electric motor 200 capable of improving the living environment (hereinafter referred to as the "control target") from among the multiple electric motors 200 and sends a control command to the selected control target. When the electric motor 200 receives the control command, it performs an operation corresponding to that control command.

[0043] For example, the storage unit 31 stores information about the controlled object (hereinafter referred to as "controlled object information") corresponding to the type of living environment for each living space. If the control unit 32 determines in the judgment process that improvement of the living environment is necessary, it identifies which living space in the building 100 has a living environment that needs improvement, based on the building information. In the identified living space, the control unit 32 selects a controlled object corresponding to the living environment that needs improvement, based on the controlled object information. The control unit 32 then transmits a control command to the selected controlled object.

[0044] The control device 30 provides the communication terminals 300 of the users of the building 100 with living environment information and status information received from each locking / unlocking device 20. The control device 30 also provides the communication terminals 300 of the users of the building 100 with the results of the determination process performed based on the living environment information received from each locking / unlocking device 20. When the control device 30 provides the results of the determination process to the communication terminals 300, it may provide the results of the determination process in association with the living space information. This allows users to understand which living spaces require improvement of the living environment.

[0045] In the following, the operation flow of the control system 1 will be explained using Figure 7. The locking / unlocking device 20 detects living environment information at regular intervals and transmits the detected living environment information to the control device 30. When the control device 30 receives the living environment information (step S101), it determines whether the living environment information is within the range of a standard value (step S102).

[0046] If the living environment information is within the range of the standard values, the control device 30 returns to the process of step S101. If the living environment information is outside the range of the standard values, the control device 30 controls an electric device 200 capable of improving the living environment indicated by that living environment information (step S103). For example, if the carbon dioxide concentration or odor concentration exceeds a set value indicating the range of the standard values, the control device 30 operates a range hood or ventilation fan.

[0047] The control device 30 may determine whether or not there is a person inside the building 100. For example, the control device 30 may determine whether or not there is a person inside the building 100 before executing step S103. For example, the control unit 32 may receive location information of a user in the building 100 from a communication terminal 300 carried by that user via a communication network NW. The control unit 32 may determine whether or not there is a person inside the building 100 based on the user's location information. However, it is not limited to this, and the control unit 32 may determine whether or not there is a person inside the building 100 based on information from sensors installed in the building 100.

[0048] The control device 30 may control the electric windows to the open state if it determines that there are people inside the building 100. For example, if there are people inside the building 100 and the carbon dioxide concentration or odor concentration exceeds a set value indicating a standard range, the control device 30 may operate the range hood or ventilation fan and control the electric windows to the open state. For example, if there are no people inside the building 100 and the carbon dioxide concentration or odor concentration exceeds a set value indicating a standard range, the control device 30 may operate the range hood or ventilation fan and control the electric windows to remain closed.

[0049] The control unit 32 may, if the heat index is outside the range of the standard value, control the electric windows to the open state, provided that there are people inside the building 100. When the control unit 32 controls the electric windows to the open state, it may also control the electric windows in the living space where the locking / unlocking device 20, which measures the temperature and humidity used to calculate the heat index, is installed, to the open state. If the heat index remains outside the range of the standard value even after the electric windows are controlled to the open state, the control unit 32 may control the electric windows to the closed state and then operate the air conditioner in cooling mode.

[0050] The control device 30 may also control the curtains, blinds, roller blinds, etc. in the living room to be closed if the illuminance in the living room exceeds a set value that indicates a range of reference values.

[0051] The locking / unlocking device 20 locks and unlocks the fixtures 110 installed in the openings of the building 100. The locking / unlocking device 20 includes a living environment detection unit 26 and an output unit 27. The living environment detection unit 26 detects living environment information indicating the living environment inside the building 100. The output unit 27 outputs the living environment information detected by the living environment detection unit 26. Since the living environment detection unit 26 is housed within the locking / unlocking device 20, the living environment inside the building can be checked while minimizing any deterioration in the building's aesthetic design.

[0052] The living environment information may consist of at least one of the following: temperature, humidity, illuminance, carbon dioxide concentration, and odor concentration. For example, by providing the locking / unlocking device 20 with an illuminance sensor that detects illuminance as living environment information, the illuminance inside the building 100 can be detected more effectively.

[0053] The output unit 27 may transmit the living environment information detected by the living environment detection unit 26 to an external device such as a control device 30 located outside the building, either by wire or wireless connection. With this configuration, the external device such as the control device 30 can centrally manage the living environment within the building 100.

[0054] The locking / unlocking device 20 may further include a locking / unlocking detection unit 25 that detects status information, which is information that can determine whether the lock used to lock and unlock the door / window 110 is in a locked state or an unlocked state. The control device 30 can manage status information of the locking / unlocking device 20 within the building 100, in addition to the living environment information.

[0055] The control device 30 may receive living environment information from the locking / unlocking device 20 via wired or wireless connection, and control one or more of the electric devices 200 from among several types of electric devices 200 based on the received living environment information. If the living environment information exceeds a standard value range, the control device 30 can improve the living environment within the building 100 by controlling the electric devices 200.

[0056] The control device 30 may, if the residential environment information indicates that at least one of the carbon dioxide concentration and odor concentration inside the building 100 is above a set value, drive a ventilation device from among the multiple types of electric devices 200 that ventilates the building 100. The control device 30 may, if the residential environment information indicates that the illuminance inside the building 100 is above a set value, drive a shielding device from among the multiple types of electric devices 200.

[0057] The locking / unlocking device 20 is not limited to a crescent lock, but may also be a thumbturn, a cremone handle, or a cam latch. [Explanation of Symbols]
