Hereinafter, it may be referred to as a switching cycle). The wireless communication device 110 is in a reception state for receiving the first setting command on the switched frequency channel. On the other hand, the first condition may start an operation of switching the frequency channel every predetermined time by the operation of the communication terminal 20, as well as when the wireless communication device 110 goes from a stop state to a start state.

Here, the first setting command includes information for transitioning the lighting device 10 and the access point 30 to the pairing setting mode, and identification information for specifying the lighting device 10. The first setting command does not include information based on the lighting signal for illuminating the surroundings by the lighting device 10. Further, 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 in the lighting device 10.

When the wireless communication device 110 receives the first setting command by operating the communication terminal 20 by the user, the second processing unit 111 operating in the switching operation may receive the first setting command in the pairing setting mode. It is determined whether or not it is a setting command for transition. If the received first setting command is a setting command for pairing, 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. do. On the other hand, in the present embodiment, the first setting command is not a command for directly setting the lighting device 10 and the access point 30, but may be a command for directly setting them. If the received first setting command is not the setting command for shifting to the pairing setting mode, the second processing unit 111 discards the setting command from the other received device and continues the switching operation. The pairing setting mode is a preparation state before directly setting the pairing of the lighting device 10 and the access point 30.

If the first setting command is a command for transitioning to the pairing setting mode, and the identification information matches the identification information held by the lighting device 10, the second condition is established. The second condition is different from the first condition. When the second condition is satisfied, the second processing unit 111 temporarily receives (for example, temporarily fixed) a predetermined frequency channel upon reception of the first setting command.

As described above, when the second condition is satisfied, the lighting device 10 switches a frequency channel every predetermined time among a plurality of frequency channels within a predetermined frequency (hereinafter sometimes referred to as a switching state of the frequency channel). ), A reception state for receiving a signal on a predetermined fixed frequency channel. More specifically, when the second condition is satisfied, the second communication unit 112 temporarily fixes the frequency channel switched among the plurality of frequency channels to a predetermined frequency channel, and receives a signal on the predetermined frequency channel. It becomes a reception state (for example, it is also called a reception state of temporary fixation).

Here, the second condition includes receiving a second setting command of the 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. Further, the second condition includes having predetermined identification information in the first setting command.

When 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 a device other than the transition to the pairing setting mode. In this case, the second processing unit 111 does not perform the transition to the pairing setting mode, discards the command of the other device received, and continues the switching operation.

Further, the second processing unit 111 transmits a signal of device information to the access point 30 when the temporary fixation is received. The device information includes, for example, identification information held by the lighting device 10.

When the reception state is reached when pairing the one or more lighting devices 10 and the access point 30, the access point 30 transmits a signal to the one or more lighting devices 10 every predetermined time, and the access point The state in which the 30 and one or more lighting devices 10 are communicating continuously or intermittently. If the lighting device 10 and the access point 30 are not paired, communication with the lighting device 10 that has not been paired with the access point 30 is disconnected. The second processing unit 111 determines whether a second setting command has been received before the specified time elapses after communication between the lighting device 10 that has not been paired and the access point 30 is cut off. When the second setting command is received before the specified time has elapsed, since it means that the lighting device 10 and the access point 30 are paired, the second processing unit 111 is set to the reception state. Information indicating the frequency channel 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 to a predetermined frequency channel stored (for example, also referred to as fixed). )do.

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

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 stored in the storage medium will be described.

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

Here, in an environment in which one or more lighting devices 10 and access points 30 are installed in a contrast medium, it is assumed that a state where one or more lighting devices 10 and access points 30 are not paired is assumed.

As shown in Fig. 4, first, the user operates the communication terminal 20 shown in Fig. 3 in order to confirm whether or not the one or more lighting devices 10 and the access point 30 have been established. The display unit 121 is operated (S1), and a communication confirmation request is transmitted to the access point 30 (S1a). In the operation display unit 121 shown in Fig. 3, information for lighting the lighting device 10 at an illumination rate of 5% is included in the communication confirmation request. This dimming rate can be arbitrarily set by the user's operation. In addition, the operation display unit 121 may select one or more lighting devices 10 in order to check whether or not the one or more lighting devices 10 and the access point 30 are established.

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

Next, when the wireless communication device 110, which is wirelessly connected to one or more lighting devices 10, receives a communication confirmation request, the lighting control unit 102 of the one or more lighting devices 10, the wireless communication device ( 110) to obtain a communication confirmation request. The lighting control unit 102 outputs a lighting signal based on the obtained communication confirmation request to the light emitting module 101, and lights it up in a predetermined state (S3).

In this way, the user can recognize that in one or more lighting devices 10, the lighting device 10 lit in a predetermined state is established in communication with the access point 30.

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 power of the lighting device 10 equipped with the wireless communication device 110, the lighting device 10 is brought into a starting state from a stopped state. At this time, the first condition is satisfied in the lighting device 10 (S11).

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

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

Next, as in step S12, when the lighting device 10 is switched to the frequency channel, and when the first setting command is received at a predetermined cycle, the user operates the communication terminal 20, and the lighting device ( 10) and the access point 30 are shifted to the pairing setting mode. The communication terminal 20 transmits the first setting command to the access point 30 by the user performing the operation of the transition to the pairing setting mode by the communication terminal 20 (S31a).

When the access point 30 receives 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). Meanwhile, multicast or unicast may be used instead of broadcast.

Next, when each lighting device 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 transitioning to the pairing setting mode. It is judged (S13). If the received first setting command is not the setting command for transitioning to the pairing setting mode (NO in S13), the process returns to step S12, and the second processing unit 111 performs the same processing.

When the received first setting command is a setting command for transitioning to the pairing setting mode (YES in S13), the second processing unit 111 has the identification information included in the first setting command, the lighting device 10 It is determined whether or not it matches the identification information (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 is the same. The processing of the.

On the other hand, when 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 first setting command. Is temporarily fixed to a predetermined frequency channel, and the second communication unit 112 is placed in a temporarily fixed reception state (S15). Thus, if it is YES in step S13 and YES in step S14, the second condition will be satisfied.

On the other hand, the establishment of the second condition needs to satisfy YES at least in step S13, and step S14 may be omitted. In this way, the lighting device 10 is in a receive state of temporarily fixed from the switching state of the frequency channel.

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

Next, when the access point 30 receives the signal of device information from the lighting device 10, the access point 30 creates a list of the lighting device 10. Based on this one or more device information, the access point 30 has a radio wave intensity other than the excluded lighting device 10 except for the lighting device 10 whose radio wave intensity with the wireless communication device 110 is less than a predetermined value. A list of lighting devices 10 having a predetermined value or more is created (S21). Then, the access point 30 transmits information indicating the list of the lighting devices 10 whose radio wave intensity is equal to or greater than a predetermined value to the communication terminal 20 (S21a). Meanwhile, step S21 will be described in detail in the following drawings.

When the communication terminal 20 receives information indicating the list of the lighting device 10, the communication terminal 20 displays the list on the operation display unit 121 of the communication terminal 20. In the list, information about the lighting device 10, such as identification information specifying the lighting device 10 and whether the lighting device 10 is paired with another access point, is displayed. 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).
