(Embodiment)
[composition]
First, the configuration of the communication system according to the embodiment will be described. FIG. 1 is a block diagram showing the functional configuration of a communication system according to an embodiment. As shown in FIG. 1, communication system 10 includes a plurality of lighting fixtures 20 and information terminal 30 .

In the communication system 10, each of the multiple lighting fixtures 20 has a wireless communication function, and the multiple lighting fixtures 20 form a mesh network. FIG. 2 is a diagram conceptually showing a mesh network. A circle mark in FIG. 2 corresponds to one lighting fixture 20 (in other words, a communication node). In a mesh network, when transmitting information from one communication node (also referred to as a first communication node) to another communication node (also referred to as a second communication node), the information is transmitted in a bucket brigade manner. be.

Specifically, when the first communication node broadcasts information including the address information (destination information) of the second communication node, other communication belonging to the same mesh network as the first communication node that has received this information Each of the nodes further broadcasts the received information. That is, each of the other communication nodes relays the information. By repeating such relaying of information within the same mesh network, the above information transmitted by the first communication node reaches all communication nodes belonging to the same mesh network as the first communication node. Therefore, the second communication node can receive the information transmitted by the first communication node.

The information transmitted through the mesh network is, for example, control information for controlling the lighting, extinguishing, or dimming of the lighting device 20 . In addition, when the mesh network includes an environmental sensor as described later, the measured value (sensing information) of the environmental sensor may be transmitted.

First, the lighting fixture 20 will be described. The lighting fixture 20 is a base light or the like that is installed on the ceiling of an indoor space to illuminate the indoor space. As described above, each of the multiple lighting fixtures 20 has a wireless communication function, and the multiple lighting fixtures 20 form a mesh network. The form of the lighting device 20 is not particularly limited, and may be a ceiling light, a downlight, a spotlight, or the like. The lighting device 20 specifically includes a wireless communication unit 21 and a light source 22 .

The wireless communication unit 21 is a wireless communication circuit for the lighting fixture 20 to perform wireless communication (more specifically, radio wave communication) with other lighting fixtures 20 and the information terminal 30 . After the lighting device 20 joins the mesh network, the wireless communication unit 21 performs communication through the mesh network described above. In addition, before the lighting device 20 joins the mesh network, the wireless communication unit 21 periodically transmits a beacon signal (sometimes called an advertisement signal, etc.), and wirelessly communicates with the information terminal 30 that has received the beacon signal. communicate. Further, the wireless communication unit 21 specifically performs wireless communication according to a communication standard such as BLE (Bluetooth (registered trademark) Low Energy) or Wi-Fi (registered trademark).

The light source 22 irradiates the indoor space with white light so that the lighting fixture 20 illuminates the indoor space. The light source 22 is realized by, for example, an LED (Light Emitting Diode) element, but may be realized by other light emitting elements such as a semiconductor laser, an organic EL (Electro Luminescence), or an inorganic EL.

Next, the configuration of the information terminal 30 will be described. The information terminal 30 is an information terminal that performs an initial setting operation for allowing a plurality of lighting fixtures 20 to join the mesh network. The information terminal 30 is, for example, a mobile terminal such as a smart phone, a tablet terminal, or a PDA (Personal Digital Assistant). Also, the information terminal 30 may be a dedicated remote controller used in the communication system 10 . The information terminal 30 is used by a user who performs initial setting work. The user here is, for example, an installer who has installed the plurality of lighting fixtures 20 on the ceiling, but may be a user other than the installer. The information terminal 30 specifically includes an operation reception unit 31 , a display unit 32 , a wireless communication unit 33 , a control unit 34 and a storage unit 35 .

The operation accepting unit 31 accepts a user's operation. The operation reception unit 31 is specifically realized by a touch panel or the like.

The display unit 32 displays images necessary for the initial setting work. The display unit 32 is implemented by, for example, a display panel such as a liquid crystal panel or an organic EL panel.

The wireless communication unit 33 is a wireless communication circuit for the information terminal 30 to perform wireless communication (more specifically, radio wave communication) with each of the lighting fixtures 20 . Specifically, the wireless communication unit 33 performs wireless communication according to a communication standard such as BLE or Wi-Fi (registered trademark).

The control unit 34 performs information processing regarding the initial setting operation according to the user's operation received by the operation receiving unit 31 . The control unit 34 is implemented by, for example, a microcomputer, but may be implemented by a processor or a dedicated circuit. The functions of the control unit 34 are realized by executing a computer program (software) stored in the storage unit 35 by hardware such as a microcomputer or a processor that constitutes the control unit 34 .

The storage unit 35 is a storage device that stores information necessary for information processing related to initial setting operations such as computer programs executed by the control unit 34 . The storage unit 35 is implemented by, for example, a semiconductor memory.

[First initial setting operation]
Next, an initial setting operation for constructing a mesh network will be described. The initial setting operation includes a first initial setting operation that associates the installation position of the lighting device 20 with the identification information of the lighting device 20, and information for allowing each of the plurality of lighting devices 20 to participate in the mesh network. and a second initialization operation (also referred to as provisioning) that stores the .

First, the first initialization operation will be described. FIG. 3 is a sequence diagram of the first initialization operation. The initial setting operation in FIG. 3 is performed, for example, after the plurality of lighting fixtures 20 are installed on the ceiling by the installer.

First, the operation accepting unit 31 of the information terminal 30 accepts from the user a start operation instructing the start of the first initial setting operation (S11).

The control unit 34 displays an initial setting screen including a map image on the display unit 32 based on the start operation accepted by the operation accepting unit 31 (S12). FIG. 4 is a diagram showing an example of an initial setting screen. The map image 32m is a top view of an area in which a plurality of lighting fixtures 20 are installed, and in the example of FIG. 4, installation positions P1 to P6 of the lighting fixtures are indicated by circles. In other words, the map image 32m is an image indicating the installation positions of the plurality of lighting fixtures 20 . The map image is stored in the storage unit 35 in advance.

At the time of step S12, it is known how the plurality of lighting fixtures 20 are arranged, but it is unknown which lighting fixture 20 is located at which place. That is, at the time of step S12, the installation position of the lighting fixture 20 and the identification information of the lighting fixture 20 are not associated.

Here, each of the plurality of lighting fixtures 20 periodically transmits a beacon signal (also called an advertisement signal or the like) before joining the mesh network. A beacon signal emitted by each of the plurality of lighting fixtures 20 includes identification information (such as a MAC address) of the lighting fixture 20 .

In this situation, the operation accepting unit 31 accepts a scan range setting operation and a scan start operation from the user (S13, S14). The scan range setting operation is, for example, a drag operation (slide operation) to the slider bar 32a on the initial setting screen of FIG. The scan range setting operation is, in other words, an operation for changing the threshold value of received signal strength, which will be described later. Also, the scan start operation is, for example, a tap operation on the scan start icon 32b on the initial setting screen of FIG.

Triggered by acceptance of the scan start operation, the wireless communication unit 33 receives a beacon signal from each of the plurality of lighting fixtures 20 (S15). Here, for convenience of explanation, it is assumed that all of the plurality of lighting fixtures 20 are located within a communicable range with the wireless communication unit 33 .

The control unit 34 measures the received signal strength of each received beacon signal, and selects a beacon signal having a received signal strength equal to or greater than a threshold among the received beacon signals (S16). The received signal strength here may be the maximum value of the received signal strength in a certain period, the average value of the received signal strength in the certain period, or the minimum value of the received signal strength in the certain period. There may be. The threshold is changed by the scan range setting operation accepted in step S13, and the wider the scan range is set, the lower (smaller) the threshold becomes.

Next, the control unit 34 displays on the display unit 32 the icon 32c of the lighting fixture 20 that is the transmission source of the selected beacon signal. In other words, the control unit 34 displays on the display unit 32 a plurality of icons 32c of a plurality of lighting fixtures 20 that are considered to be positioned within a predetermined range with respect to the information terminal 30 (S17). FIG. 5 is a diagram showing an example of an initial setting screen displaying a plurality of icons 32c of the lighting device 20. The plurality of icons 32c are displayed in a horizontal row. The plurality of icons 32c can also be considered as icons (indicating identification information) corresponding to identification information included in the beacon signal selected in step S16.

Next, the operation receiving unit 31 receives from the installer an operation for selecting a plurality of icons 32c (S18). The selection operation is, for example, a tap operation on any one of the plurality of icons 32c. The control unit 34 causes the wireless communication unit 33 to transmit a flashing command based on the selection operation accepted by the operation accepting unit 31 (S19). The flashing command is transmitted, for example, when a tap operation on the flashing icon 32d is accepted after the selection operation.

The blinking command specifies the identification information of the lighting device 20 corresponding to the selected icon 32c. The flashing command is a signal for selectively flashing the target lighting fixture 20 having the identification information among the plurality of lighting fixtures 20 . The target lighting fixture 20 among the plurality of lighting fixtures 20 blinks when receiving the blinking command (S20).

The user operating the information terminal 30 visually confirms the actual installation position of the target lighting fixture 20 that is blinking (S21), and locates the target lighting fixture 20 that is blinking on the map image 32m. Specify the installation position (for example, one of the installation positions P1 to P6). The operation reception unit 31 receives from the user an operation for specifying the installation position of the lighting device 20 in the map image 32m (S22). Then, the control unit 34 associates the identification information indicated by the icon 32c selected in step S18 with the installation position specified in step S22 and stores them in the storage unit 35 (S23). Also, the control unit 34 cancels the display of the icon 32c for which the association has been completed (S24). That is, the number of icons 32c displayed in step S15 is decreased by one.

The processing of steps S16 to S24 is repeated until all the icons 32c (identification information) displayed in step S17 are associated with the installation positions. Further, when the beacon signals of all the lighting fixtures 20 cannot be received in step S15, the user holding the information terminal 30 moves to another location, and after the communicable range of the wireless communication unit 33 is changed, , the processing of steps S13 to S22 is performed again. As a result, the storage unit 35 stores correspondence information indicating correspondence between the identification information of the plurality of lighting fixtures 20 and their installation positions. FIG. 6 is a diagram showing an example of correspondence information.

As described in step S21 above, the actual installation position of the lighting device 20 and the position on the map image 32m are checked visually by the user. Then, if no threshold is set for the received signal strength, in step S17, many icons 32c including the icon 32c of the lighting device 20 far away from the user will be displayed. FIG. 7 is a diagram for explaining the number of icons 32c of the lighting fixtures 20 displayed on the information terminal 30 when no threshold is set for the received signal strength.

When the icon 32c of the lighting fixture 20 far away from the user is selected, the lighting fixture 20 far away from the user blinks, and the user cannot grasp the exact installation position of the lighting fixture 20 that is blinking. You need to move to know your position. In other words, there is a problem that work is delayed.

To address such a problem, the information terminal 30 sets a threshold for the received signal strength, and selectively displays only the icon 32c of the lighting device 20 that is the source of the beacon signal whose received signal strength is equal to or greater than the threshold on the display unit 32. (See steps S16 and S17 above). If the threshold is set high, only the icons 32c of the lighting fixtures 20 located near the information terminal 30 are displayed, as shown in FIG. FIG. 8 is a diagram for explaining the number of icons 32c of lighting fixtures 20 displayed on the information terminal 30 when thresholds are provided for received signal strength.

If only the icon 32c of the lighting fixture 20 positioned near the information terminal 30 is selectively displayed in this manner, it is less likely that the user will not be able to grasp the correct installation position of the lighting fixture 20 that is blinking. . That is, work efficiency can be improved.

Note that it is not essential that the information terminal 30 has a configuration that allows the threshold to be changed, and the threshold may be a predetermined fixed value. The threshold in this case may be appropriately determined empirically or experimentally so that only the icon 32c of the lighting device 20 located near the information terminal 30 is displayed.

[Second initial setting operation]
Next, a second initialization operation (also referred to as provisioning) will be described. FIG. 9 is a sequence diagram of the second initialization operation.

First, the operation accepting unit 31 of the information terminal 30 accepts from the user a start operation instructing the start of the second initial setting operation (S31). The start operation includes an operation of specifying identification information of the lighting device 20 and the like. The control section 34 performs unicast communication with the lighting fixture 20 having the identification information designated by the start operation, and causes the wireless communication section 33 to transmit the setting information to the lighting fixture 20 (S32). The lighting fixture 20 receives the setting information and stores it in a storage unit (not shown) provided in the lighting fixture 20 (S33).

The setting information is information for the lighting device 20 to join the mesh network. The setting information includes the network ID of the mesh network to which the lighting device 20 belongs, and the address information (unicast address) of the lighting device 20 used for communication within the mesh network. The setting information may include a security passcode used for communication within the mesh network, information on the information terminal 30 (information on the device that manages the mesh network), and the like, if necessary. If the lighting fixture 20 is a higher node that can communicate with lighting fixtures 20 belonging to other meshwork, the setting information may include information necessary for the lighting fixture 20 to function as a higher node. .

The lighting fixture 20 whose setting information is stored in the storage unit can participate in the mesh network. The processing of steps S31 to S33 is repeated until all lighting fixtures 20 enter the mesh network. A lighting fixture 20 that joins the mesh network stops the periodic transmission of beacon signals that it did before joining.

Note that the processing of steps S31 to S33 may be included in the first initialization operation (FIG. 4). For example, the processing of steps S31 to S33 may be performed on the target lighting device 20 after step S23 of the first initialization operation.

[Modification]
In step S17 of the first initial setting operation, the icon 32c of the lighting fixture 20 (hereinafter also referred to as the first lighting fixture) that is the source of the beacon signal whose received signal strength is equal to or greater than the threshold is displayed. The icon 32c of the lighting device 20 (hereinafter, also referred to as the second lighting device) that is the source of the beacon signal whose V is less than the threshold was not displayed. However, the icon 32c for the second lighting fixture may be displayed in a different manner than the icon for the first lighting fixture. For example, the icon for the first lighting fixture may be displayed in color, and the icon for the second lighting fixture may be washed out (grayscale display).

If the icon 32c of the lighting fixture 20 positioned near the information terminal 30 and the icon 32c of the lighting fixture 20 positioned far from the information terminal 30 are displayed separately in this manner, the user can visually identify the position. By selecting only the icon of the lighting fixture 20 located near the information terminal 30, which is suitable for confirmation, it is possible to associate the identification information with the installation position. That is, the user can improve the efficiency of the work of associating with the identification information.

Further, in step S17 of the first initial setting operation, the blinking command was transmitted from the information terminal 30 to the target lighting fixture 20 . Here, the flashing command is an example of a control command for causing the target lighting fixture 20 to transition to a state different from that of the other lighting fixtures 20, and the control unit 34 sends a control command other than the flashing command to the wireless communication unit 33. You may make it transmit to the lighting fixture 20 of object.

For example, when the target lighting device 20 and the other lighting devices 20 are in the off state, the control unit 34 issues a lighting command (another example of a control command) for transitioning the target lighting device 20 to the lighting state. may be transmitted to the target lighting device 20 by the wireless communication unit 33 . When the target lighting fixture 20 and the other lighting fixtures 20 are in a lighting state, the control unit 34 wirelessly transmits a turn-off command (another example of a control command) for transitioning the target lighting fixture 20 to a turned-off state. You may make the communication part 33 transmit to the lighting fixture 20 of object. In this way, the control command may be a command for causing the light source 22 provided in the target lighting device 20 to emit light or extinguish in a manner different from that of the light sources 22 provided in other lighting devices 20 .

In addition, in the above embodiment, the mesh network is configured by the information terminal 30 and the plurality of lighting fixtures 20, but the mesh network consists of the information terminal 30 and a plurality of other devices (devices other than the lighting fixtures 20). may be configured. Also, the mesh network may include other devices in addition to the information terminal 30 and the plurality of lighting fixtures 20 .

Examples of the other devices include a lighting remote controller operated by the user to control the lighting fixture 20, an AC relay, and the like. An AC relay is, for example, a device that is attached to a wiring duct and can turn on and off a lighting fixture attached to the wiring duct by turning on and off the supply of AC power to the wiring duct. is.

Also, the other devices may be devices that are not directly related to lighting, such as air conditioners, ventilators, cameras, motion sensors, or environment sensors. Environmental sensors include temperature sensors, humidity sensors, carbon dioxide concentration sensors, PM (Particle Matter) sensors, and the like.

In the above-described embodiment, the light source 22 included in the lighting fixture 20 is used as the state presentation unit for the user to visually confirm the installation position of the lighting fixture 20 . However, since the devices that make up the mesh network are not limited to the lighting fixtures 20, various modes are conceivable for the state presentation unit provided in each device.

For example, each device may include a light source (such as an LED indicator if the device is not lighting fixture 20) as a status indicator. Each device may include a speaker as a state presenting unit and present the state by outputting sound. Each device may use a dedicated function of the device (such as a fan function when the device is an air conditioner) as a state presentation unit. In addition, based on the control command transmitted from the information terminal 30, the state presentation unit may present a state different from that of the state presentation units provided in other devices.
