The illumination control unit 102 can be configured using, for example, a microcomputer having a CPU (Central Processing Unit). The lighting control unit 102 can perform a predetermined lighting control operation, for example, by executing a program stored in the memory unit. The memory unit can be configured using, for example, a non-volatile semiconductor memory such as flash memory or EEPROM (Electrically Erasable and Programmable Read Only Memory).

The lighting control unit 102, via the wireless communication device 110, confirms whether or not communication has been established between the lighting device 10 and the access point 30 before pairing is set between one or more lighting devices 10 and the access point 30.

In the present embodiment, lighting device 10 is equipped with wireless communication device 110, but is not limited to this. Wireless communication device 110 and lighting device 10 are separate devices, and wireless communication device 110 is lighting device. 10 and may be communicably connected to the lighting device 10 .

The wireless communication device 110 is a communication module mounted on the lighting device 10, and can wirelessly communicate with the wireless communication device 110 mounted on another lighting device 10 different from the lighting device 10, the access point 30, and the like. . Upon receiving a communication confirmation request from the access point 30 before pairing the lighting device 10 and the access point 30 , the wireless communication device 110 transmits the communication confirmation request to one or more lighting devices 10 .

Also, the wireless communication device 110 performs the following processing in pairing setting between the lighting device 10 and the access point 30 . Wireless communication device 110 has second processing unit 111 , second communication unit 112 , and storage unit 113 .

When the first condition is satisfied, the second processing unit 111 switches frequency channels among a plurality of frequency channels within a predetermined frequency every predetermined time (hereinafter sometimes referred to as switching operation), and performs switching. The second communication unit 112 is put into a receiving state so as to receive the first setting command on the specified frequency channel.

Here, the first condition includes activation of the stopped wireless communication device 110, that is, an activation state in which the power of the wireless communication device 110 is turned on from a stopped state in which the power of the wireless communication device 110 is turned off. . In addition, the first condition is that the wireless communication device 110, which has been in the stopped state after the lapse of a specified time since the communication between the wireless communication device 110 and the access point 30 is interrupted, and the second condition described later, is brought into the active state. including at least one of becoming

That is, when the wireless communication device 110 changes from the stopped state to the activated state, the second processing unit 111 automatically switches the frequency channel among the plurality of frequency channels every predetermined time (that is, periodically switches the frequency channel). (hereinafter referred to as switching period). The wireless communication device 110 enters a receiving state to receive the first setting command on the switched frequency channel. Note that the first condition is not limited to the case where the wireless communication device 110 is switched from the stopped state to the activated state, but the operation of the communication terminal 20 may start the operation of switching the frequency channel every predetermined time.

Here, the first setting command includes information for switching the lighting device 10 and the access point 30 to the pairing setting mode, and identification information specifying the lighting device 10 . The first setting command does not include information based on the lighting signal for illuminating the surroundings with the lighting device 10 . The identification information is a unique word held by the lighting device 10 for specifying the lighting device 10 and is stored in a storage device (not shown) of the lighting device 10 .

When the user operates the communication terminal 20 so that the wireless communication device 110 receives the first setting command, the second processing unit 111 that is switching operates, because the received first setting command shifts to the pairing setting mode. Determines whether it is a setting command for If the received first setting command is a setting command for pairing setting, the second processing unit 111 determines whether the identification information included in the first setting command matches the identification information held by the lighting device 10. judge. In the present embodiment, the first setting command is not a command for directly pairing the lighting device 10 and the access point 30, but is a command for directly pairing them. good too. If the received first setting command is not a setting command for shifting to the pairing setting mode, the second processing unit 111 discards the received setting command from another device and continues the switching operation. The pairing setting mode is a preparatory state before directly setting the pairing between the lighting device 10 and the access point 30 .

When the first setting command is a command for shifting to the pairing setting mode and this identification information matches the identification information held by the lighting device 10, the second condition is satisfied. The second condition is different than the first condition. When the second condition is satisfied, the second processing unit 111 enters a reception state in which the frequency channel is temporarily fixed (for example, temporarily fixed) to a predetermined frequency channel at the time of reception of the first setting command. When the second condition is satisfied in this way, the lighting device 10 is in a state of switching frequency channels among a plurality of frequency channels within a predetermined frequency at predetermined time intervals (hereinafter sometimes referred to as a frequency channel switching state. ) to a receiving state in which a signal is received on the temporarily fixed predetermined frequency channel. More specifically, when the second condition is satisfied, the second communication unit 112 temporarily fixes the frequency channel to be switched among the plurality of frequency channels to a predetermined frequency channel, and temporarily fixes the predetermined frequency channel. , the signal is received (for example, it is also called a temporarily fixed reception state).

Here, the second condition includes receiving a second setting command for a frequency channel among the plurality of frequency channels and temporarily fixing the frequency channel of the received second setting command as a predetermined frequency channel. Also, the second condition includes having predetermined identification information in the first setting command.

If the identification information included in the first setting command does not match the identification information held by the lighting device 10, the received first setting command is a command from another device other than the transition to the pairing setting mode. . In this case, the second processing unit 111 does not switch to the pairing setting mode, discards the received command of the other device, and continues the switching operation.

In addition, the second processing unit 111 transmits a signal of device information to the access point 30 when the temporarily fixed reception state is reached. The device information includes, for example, identification information held by the lighting device 10 .

When one or more lighting devices 10 and an access point 30 are paired and set to be in a reception state, the access point 30 transmits a signal to one or more lighting devices 10 at predetermined time intervals to access the lighting device 10. Communication between point 30 and one or more lighting devices 10 is maintained continuously or intermittently. If the lighting device 10 and the access point 30 are not paired, communication between the access point 30 and the lighting device 10 for which pairing is not set is lost. The second processing unit 111 determines whether or not the second setting command is received before a specified time elapses after communication between the lighting device 10 and the access point 30, which have not been paired, is interrupted. If the second setting command is received before the specified time elapses, it means that the lighting device 10 and the access point 30 have been paired. information indicating the frequency channel of is stored in the storage unit 113 . Information indicating a predetermined frequency channel is stored in the storage unit 113, and the lighting device 10 and the access point 30 are fixed (for example, also referred to as permanent fixation) to the stored predetermined frequency channel.

Here, the second setting command is a command for directly setting the pairing between the lighting device 10 and the access point 30, and is information indicating a list of lighting devices 10 received from one or more lighting devices 10 (described later). and information indicating the presence or absence of pairing settings corresponding to each of the one or more lighting devices 10 .

The second communication unit 112 is configured by a radio module such as an antenna. The second communication unit 112 receives the first setting command and the second setting command from the access point 30 and transmits a signal of device information to the access point 30 . The second communication unit 112 wirelessly communicates with the access point 30, other lighting devices 10, and the like by optical wireless communication such as infrared rays, NFC (Near Field Communication), or the like. Note that the second communication unit 112 may communicate directly with the communication terminal 20 by radio.

The second communication unit 112 uses specific low-power radio, Zigbee (registered trademark), Bluetooth (registered trademark), Wi-Fi, etc., using frequencies such as the 920 MHz band or the 2.4 GHz band, as a method for wirelessly communicating with the access point 30. (registered trademark) and other methods are used.

Next, the operation of the access point 30, the wireless communication device 110, the lighting device 10, the lighting system 1, the communication method, and the program will be described.

FIG. 3 is a schematic diagram illustrating an operation screen displayed on the operation display unit 121 when making a communication confirmation request using a communication terminal in the lighting system 1 according to the embodiment. FIG. 4 is a flow chart illustrating the operation of the lighting system 1 according to the embodiment.

Here, in an environment where one or more lighting devices 10 and access points 30 are installed on a construction material, it is assumed that one or more lighting devices 10 and access points 30 are not paired.

As shown in FIG. 4, first, the user operates the operation display unit of the communication terminal 20 shown in FIG. 121 (S1), and transmits a communication confirmation request to the access point 30 (S1a). In the operation display unit 121 shown in FIG. 3, the communication confirmation request includes information for lighting the lighting device 10 at a dimming rate of 5%. This dimming rate can be arbitrarily set by a user's operation. Also, in the operation display unit 121, one or more lighting devices 10 can be selected in order to confirm whether or not communication has been established between one or more lighting devices 10 and the access point 30. FIG.

Next, upon receiving the communication confirmation request from the communication terminal 20, the access point 30 transmits the communication confirmation request to one or more lighting devices 10 (S1b).

Next, when the wireless communication device 110 that is wirelessly communicably connected to one or more lighting devices 10 receives the communication confirmation request, the lighting control unit 102 of the one or more lighting devices 10 receives the communication confirmation request from the wireless communication device 110. to get The lighting control unit 102 outputs a lighting signal based on the acquired communication confirmation request to the light emitting module 101 to light it in a predetermined state (S3).

Thus, the user can recognize that communication with the access point 30 has been established for one or more lighting devices 10 that are lit in a predetermined state.

FIG. 5 is a sequence diagram illustrating the operation of the lighting system 1 according to the embodiment.

As shown in FIG. 5, first, when the user turns on the lighting device 10 having the wireless communication device 110 mounted thereon, the lighting device 10 changes from the stopped state to the activated state. At this time, the lighting device 10 satisfies the first condition (S11).

Next, when the first condition is satisfied, the illumination device 10 enters a frequency channel switching state, and enters a reception state for receiving the first setting command on a predetermined frequency channel. That is, the lighting device 10 switches the frequency channel among the plurality of frequency channels at predetermined time intervals, and enters a reception state in which the switched frequency channel receives the first setting command (S12).

For example, when the predetermined frequency that can be received by the lighting device 10 is the 920 MHz band, there are a plurality of frequency channels in the 920 MHz band, such as 923.8 MHz for 1ch, 924 MHz for 2ch, and 925.6 MHz for 10ch. assigned. When the second processing unit 111 of the wireless communication device 110 mounted in the lighting device 10 switches the frequency channel among odd-numbered frequency channels, the second processing unit 111 can receive the first setting command on channel 1 for a predetermined period of time. 1ch is switched to 3ch, and 3ch becomes ready to receive the first setting command for a predetermined time. Then, the second processing unit 111 periodically repeats switching from 3ch to 5ch, switching from 5ch to 7ch, switching from 7ch to 9ch, and switching from 9ch to 1ch at predetermined time intervals.

Next, as in step S12, when the lighting device 10 enters the frequency channel switching state and enters the reception state of the first setting command at a predetermined cycle, the user operates the communication terminal 20 to switch the lighting device 10 and the access point 30. to the pairing setting mode. When the user operates the communication terminal 20 to switch to the pairing setting mode, the communication terminal 20 transmits the first setting command to the access point 30 (S31a).

Upon receiving the first setting command from the communication terminal 20, the access point 30 broadcasts the first setting command to one or more lighting devices 10 (S31b). It should be noted that instead of broadcasting, multicast or unicast may be used.

Next, when each of the lighting devices 10 receives the first setting command, the second processing unit 111 in the switching operation determines whether the received first setting command is a setting command for shifting to the pairing setting mode. It is determined whether (S13). If the received first setting command is not a setting command for shifting to the pairing setting mode (NO in S13), the process returns to step S12, and the second processing unit 111 performs similar processing.

If the received first setting command is a setting command for shifting to the pairing setting mode (YES in S13), the second processing unit 111 determines that the identification information included in the first setting command is the It is determined whether or not the identification information matches (S14).

If the identification information included in the first setting command does not match the identification information held by the lighting device 10 (NO in S14), the process returns to step S12, and the second processing unit 111 performs similar processing.

On the other hand, if the identification information included in the first setting command matches the identification information held by the lighting device 10 (YES in S14), the second processing unit 111 receives the predetermined setting command when the first setting command is received. The frequency channel is temporarily fixed, and the second communication unit 112 is brought into the temporarily fixed receiving state (S15). Thus, if YES in step S13 and YES in step S14, the second condition is established.

In order for the second condition to be established, it is necessary to satisfy YES at least in step S13, and step S14 may be omitted. In this manner, the lighting device 10 changes from the frequency channel switching state to the temporarily fixed receiving state.

Next, the second communication unit 112 of the wireless communication device 110 mounted on the lighting device 10 transmits the identification information of its own device (the lighting device 10) to the access point 30 (S15a).

Next, when the access point 30 receives the device information signal from the lighting device 10 , the access point 30 creates a list of the lighting devices 10 . Based on the one or more pieces of device information, the access point 30 excludes lighting devices 10 whose radio wave intensity with respect to the wireless communication device 110 is less than a predetermined value. A list of lighting devices 10 is created (S21). Then, the access point 30 transmits to the communication terminal 20 information indicating a list of lighting devices 10 whose radio wave intensity is equal to or greater than a predetermined value (S21a). Note that step S21 will be described in detail in the next figure.

When receiving the information indicating the list of the lighting devices 10 , the communication terminal 20 displays the list on the operation display unit 121 of the communication terminal 20 . The list displays information about the lighting device 10, such as identification information for specifying the lighting device 10 and whether or not the lighting device 10 is paired with another access point. The user selects the lighting device 10 that can be paired with the access point 30 based on the list displayed on the operation display unit 121 (S32).

Next, the wireless communication device 110 transmits to the access point 30 a second setting command including information indicating one or more lighting devices 10 selected by the user (S32a).

Next, upon receiving the second setting command from the wireless communication device 110, the access point 30 transmits the second setting command to one or more lighting devices 10 selected by the user (S32b).

Next, when the lighting device 10 receives the second setting command, the wireless communication device 110 of the lighting device 10 causes the storage unit 113 to store information indicating the temporarily fixed predetermined frequency channel (S16). In this way, the communication between the lighting device 10 and the access point 30 is permanently fixed to the predetermined frequency channel, and the fixed reception state is established. Thus, the lighting device 10 and the access point 30 are paired, and the lighting system 1 ends the processing of this flow.

As a result, for example, even when the lighting device 10 is in a stopped state, the lighting device 10 reads out the information indicating the predetermined frequency channel stored in the storage unit 113, thereby wirelessly communicating with the paired wireless communication device 110. It can be performed.

Next, the processing from step S15a to step S21 and step S21a in FIG. 5 will be described in detail with reference to FIG.

FIG. 6 is a flow diagram illustrating processing based on radio wave intensity between access point 30 and lighting device 10 in the pairing setting mode according to the embodiment.

As shown in FIG. 6, when the access point 30 receives a signal of device information from one or more lighting devices 10 in step S15a, the first processing unit 131 generates radio waves between the one or more lighting devices 10 and the access point 30. It is determined whether or not the intensity is less than a predetermined value, that is, whether or not there is a lighting device 10 whose radio field intensity is less than a predetermined value (S121).

If there is a lighting device 10 whose radio wave intensity is less than the predetermined value (YES in S121), the first processing unit 131 excludes the lighting device 10 whose radio wave strength is less than the predetermined value, and is other than the excluded lighting device 10. , a list of lighting devices 10 whose radio wave intensity is equal to or greater than a predetermined value is created (S21). The first processing unit 131 transmits, to the communication terminal 20, information indicating a list of lighting devices 10 whose radio wave intensity is equal to or greater than a predetermined value (S122). The access point 30 then advances the process to step S21a.

If there is no lighting device 10 whose radio wave intensity is less than the predetermined value (NO in S121), a list of lighting devices 10 is created based on all the received device information (S123), and the process proceeds to step S122.

Further, in the access point 30 according to the present embodiment, the first communication unit 132 transmits the first setting command to one or more lighting devices 10 among the lighting devices 10 that are lit in a predetermined state in response to the communication confirmation request. and a second setting command (an example of a signal for setting pairing).

According to this, the user selects the lighting device 10 from among the one or more lighting devices 10 with which communication has been established with the access point 30, thereby pairing the one or more lighting devices 10 desired by the user with the access point 30. Ring can be set.

Also, wireless communication apparatus 110 according to the present embodiment communicates with access point 30 . Wireless communication device 110 receives the transmitted lighting signal or communication confirmation request (an example of a signal), and transmits lighting signal or communication confirmation request for lighting lighting device 10 in a predetermined state based on the received lighting signal or communication confirmation request. A communication confirmation request is transmitted to the lighting device 10 .

According to this, the wireless communication device 110 can receive from the access point 30 a communication confirmation request for lighting in a predetermined state before pairing setting, and the wireless communication device 110 can light in a predetermined state after pairing setting. A lighting signal for this purpose can be received from the access point 30 . Thereby, the illumination device 10 can be lit in a predetermined state.

In addition, wireless communication apparatus 110 according to the present embodiment controls lighting apparatus 10 based on a device information signal received with a predetermined radio wave intensity or higher among received device information signals (an example of signals). A lighting signal is sent to turn on the LED in the state.

Further, lighting device 10 according to the present embodiment lights in a predetermined state based on the communication confirmation request received by wireless communication device 110 .

According to these, the lighting device 10 can be lit in a predetermined state.

Moreover, lighting device 10 according to the present embodiment lights in a predetermined state based on a device information signal received by wireless communication device 110 with a predetermined radio wave intensity or higher.

For example, even if the lighting device 10 and the access point 30 can communicate, the lighting device 10 and the access point 30 may not communicate with each other due to changes in the environment of the facility where the lighting device 10 and the access point 30 are installed. sometimes it becomes impossible.

However, according to this lighting device 10, if the threshold of the reception intensity at which communication between the lighting device 10 and the access point 30 is possible is equal to or greater than the predetermined radio wave intensity, the facility environment in which the lighting device 10 is installed changes. Also, it is possible to suppress the problem that the illumination device 10 and the access point 30 cannot communicate with each other.
