  The communication unit 41 is constructed by the wireless communication IC 22 and wirelessly communicates with other wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 or the management device KS. Therefore, the communication unit 41 functions as a communication unit.

  The identification information storage unit 42 is constructed by the nonvolatile memory 23 and stores at least own group identification information for identifying the own group to which the own device belongs, for example, own group ID (Identification). Therefore, the identification information storage unit 42 functions as a device information storage unit. The information storage unit 42 according to the present embodiment stores not only the own group identification information but also own device identification information for identifying the own device, for example, the own device ID.

  The communication type determination unit 43 is constructed by the microcomputer 21. When the communication unit 41 receives wireless communication, the communication type determination unit 43 determines whether the destination of the wireless communication is addressed to the own group. That is, the communication type determination unit 43 checks whether the wireless communication destination group received by the communication unit 41 matches the own group identification information stored in the identification information storage unit 42, and determines the wireless communication destination. Determine if is addressed to its own group. Therefore, the communication type determination unit 43 functions as a communication type determination unit. Further, the communication type determination unit 43 determines whether the wireless communication received by the communication unit 41 is a response wireless communication transmitted by the other wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 of the own group.

  The response transmission unit 44 is constructed by the microcomputer 21, and when the communication type determination unit 43 determines that the wireless communication received by the communication unit 41 is wireless communication addressed to the own group, the response transmission unit 44 sends a response to the wireless communication to the communication unit 41.

It is determined whether the wireless communication is a response. That is, the response determination unit 45 is the own group in which the device identification information of the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 of the wireless communication received by the communication unit 41 is stored in the identification information storage unit 42. It is checked whether it matches with the device identification information belonging to. When the identification information of the source wireless communication devices Ma1 to Ma4, Mc1 to Mc4 matches the device identification information of the identification information storage unit 42, the response determination unit 45 It is determined that the wireless communication is the response wireless communication transmitted by the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4. In this case, the response determination unit 45 confirms that the wireless communication is a response wireless communication by acquiring from the wireless communication data. Note that the response determination unit 45 determines whether the group identification information of the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 that are transmission sources of wireless communication matches the own group identification information stored in the identification information storage unit 42. It may be determined whether or not it belongs to its own group.

  Then, in the response transmission unit 44, the response determination unit 45 determines that the wireless communication received by the communication unit 41 is a response wireless communication, and the communication unit 41 does not receive the wireless communication corresponding to the response. If it is determined that the response is a response to the response, the communication unit 41 is caused to transmit a response wireless communication to which information indicating that the response is added.

  The response control unit 46 is constructed by the microcomputer 21. The response control unit 46 indicates that the wireless communication received by the communication unit 41 is wireless communication of a response transmitted to the wireless communication addressed to the own group by the other wireless communication devices Ma1 to Ma4 to Mc1 to Mc4. When the response determination unit 45 determines, the response transmission unit 44 stops transmitting a response to the wireless communication that is the response target of the wireless communication. Therefore, the response control unit 46 functions as a response control unit.

  The transfer unit 47 is constructed by the microcomputer 21. When the communication unit 41 receives wireless communication of a response to which information indicating that it is a response to the response from other wireless communication devices Ma1 to Ma4, Mc1 to Mc4 of the own group, the communication unit 41 receives the response. The response is transferred to the other wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 or the management device KS. Therefore, the transfer unit 47 functions as a transfer unit.

The identification information adding unit 48 includes device identification information (self device ID or the like) for identifying the own device in a response transmitted from the response transmission unit 44 or the transfer unit 47. Therefore, the identification information adding unit 48 functions as identification information adding means.

  Next, functional blocks of the management device KS will be described. The management device KS is constructed by introducing a normal wireless communication management program into the management device KS. The management communication unit 51 is constructed by the communication I / F 17 and wirelessly communicates with the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4. Therefore, the management communication unit 51 functions as a management communication unit.

  The communication control unit 52 is constructed by the CPU 11 and performs wireless communication including instructions to the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 via the management communication unit 51. Therefore, the communication control unit 52 functions as a communication control unit.

  The management unit 53 is constructed by the CPU 11 and based on responses from the wireless communication devices Ma1 to Ma4, Mc1 to Mc4, which are transmission destinations of wireless communication received by the management communication unit 51, the wireless communication devices Ma1 to Ma1. Ma4,..., Mc1 to Mc4 are managed. Therefore, the management unit 53 functions as a management unit.

  Next, the operation of this embodiment will be described. The wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 of this embodiment reduce the number of wireless communication and suppress radio wave interference. In the wireless communication system 1, the management device KS performs wireless communication with the wireless communication devices Ma1 to Ma4 of the group GrA, for example, as indicated by arrows in FIG. As will be described later, only one wireless communication device Ma1 to Ma4 belonging to the group GrA transmits a response to the management device KS among the wireless communication devices Ma1 to Ma4 of the group GrA. In FIG. 6, the wireless communication device Ma1 transmits a response to the management device KS.

  In this case, for example, the management device KS transmits wireless communication (transmission data) having a data configuration as illustrated in FIG. 7A by multicast with the wireless communication devices Ma1 to Ma4 of the group GrA as transmission destinations. As shown in FIG. 7A, the data structure of wireless communication transmitted by the management apparatus KS includes a sequence number, a destination (individual / group), a transmission source, a command, and data. The sequence number is information for specifying transmission data, and is “01”, for example. The destination (individual / group) is information for specifying the transmission destination of the transmission data. Individually, information for specifying the wireless communication devices Ma1 to Ma4,..., Mc1 to Mc4 (Ma1 etc.), and for the group, the group is specified. Information (for example, group GrA). The transmission source is information indicating a transmission source of transmission data, and is, for example, a management device ID, wireless communication devices Ma1 to Ma4, IDs of Mc1 to Mc4, and the like. The command is the content (command) requested by the transmission data, such as “lights out”, “response”, and the like. The data is the detailed contents of the command, but is not set in FIG.

  When the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 receive wireless communication (transmission data) from the management device KS that designates the groups GrA to GrC, one wireless communication device Ma1 to Ma4 of the group GrA to GrC is received. , ~, Only Mc1-Mc4 send responses.

  The wireless communication (transmission data) of this response has a data configuration as shown in FIG. That is, the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 manage response wireless communication (response data) having a data structure including a sequence number, a destination (individual / group), a transmission source, a command, and a transmission source group. Send to KS.

  The sequence number is the same as the sequence number of the received command (for example, the wireless communication sequence number of the command in FIG. 7A). As will be described later, when other wireless communication devices Ma1 to Ma4,..., Mc1 to Mc4 of the same group GrA to GrC receive the response wireless communication, this is a response to the command of the sequence number. Like that. That is, it is possible to determine whether or not the other wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 of the same group GrA to GrC have received the wireless communication of the command corresponding to the wireless communication of the response by the sequence number. It is to make it. Note that the relationship between the response and the command is not limited to the case of judging by the sequence number. For example, the command and the response are linked by giving a unique ID to the wireless communication of the command and the response. May be.

  The destination is the management device, and the transmission source is the device ID of the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 that transmitted the response, for example, Ma1. The command is the content (response) requested of the transmission data. The transmission source group is identification information of the groups GrA to GrC to which the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 that transmitted the transmission data belong, such as Gra.

  And the radio | wireless communications system 1 transmits radio | wireless communication to the radio | wireless communication apparatuses Ma1-Ma4 of a group GrA-GrC to which operation | movement is performed from the management apparatus KS, and Mc1-Mc4. In this case, only one wireless communication device Ma1 to Ma4 to Mc1 to Mc4 of the group GrA to GrC performs wireless communication in response to the management device KS.

  For example, as illustrated in FIG. 1, when the management apparatus KS performs wireless communication of a command destined for the group GrB, normally, as illustrated in FIG. 1 as “reception”, all the wireless communication apparatuses Mb1 of the group GrB. -Mb4 receives wireless communication.

  Now, of the wireless communication devices Mb1 to Mb4 in the group GrB, when the wireless communication device Mb4 receives the wireless communication earliest, as shown in FIG. 8, the wireless communication device Mb4 responds with a response addressed to the management device KS. Send wireless communication. This response wireless communication is received not only by the management device KS, but also by the other wireless communication devices Mb1 to Mb3 of the same group GrB as shown as “reception” in FIG.

  When the other wireless communication devices Mb1 to Mb3 receive the wireless communication in response to the command, the wireless communication devices Mb1 to Mb3 determine that the response is unnecessary as shown in FIG. Therefore, the radio communication system 1 can reduce the total number of radio communications, and can suppress radio wave interference.

  Then, the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 execute wireless communication processing as shown in FIG. That is, when the communication unit 41 receives a wireless communication, the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 check whether the wireless communication destination is the management device KS (step S101). ).

  If the destination of wireless communication is not the management device KS in step S101 (NO in step S101), the communication type determination unit 43 checks whether it is addressed to the own device (step S102). That is, the communication type determination unit 43 checks whether or not its own device ID (for example, Ma1) is set as the destination of the wireless communication. In this case, for example, the management device KS selects the individual wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 among the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4, or the groups GrA to GrC. Then, the wireless communication as shown in FIG.

  In step S102, if the destination of wireless communication is the device itself (YES in step S102), the response transmitter 44 transmits a response via the communication unit 41 as shown in FIG. 8 (step S103). ). This response is, for example, response data as shown in FIG.

  When the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 perform response transmission, the wireless communication devices execute the command of the wireless communication command and end the wireless communication process (step S104).

  In step S102, if it is not addressed to its own device (NO in step S102), the communication type determination unit 43 checks whether it is addressed to its own group GrA to GrC (step S105).

  In step S105, if it is not addressed to its own group GrA to GrC (NO in step S105), the response determination unit 45 discards the wireless communication as irrelevant to its own device or its own group GrA to GrC. The wireless communication process is terminated (step S106).

  In step S105, if it is addressed to its own group GrA to GrC (YES in step S105), the response control unit 46 checks whether a response unnecessary flag for the same sequence number is set (step S107). That is, as will be described later, the response control unit 46 determines whether or not the other wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 belonging to the same group GrA to GrC have transmitted a response to the wireless communication.

  If a response unnecessary flag is set for the same sequence number in step S107 (YES in step S107), the response control unit 46 causes the response transmission unit 44 to stop transmitting the response. The wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 execute the command of the wireless communication command and end the wireless communication process (step S104).

  If a response unnecessary flag is not set for the same sequence number in step S107 (NO in step S107), the response control unit 46 transmits a response wireless communication to the response transmission unit 44 via the communication unit 41. Transmit (step S108). Then, the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 execute the command of the wireless communication command. Then, the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 end the wireless communication process (step S104).

  In step S101, when the destination of wireless communication is the management device KS (when YES in step S101), the response determination unit 45 determines that the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 of the transmission source are their own devices. It is checked whether it is the same group GrA to GrC (step S109).

  In step S109, if the wireless communication devices Ma1 to Ma4 of the transmission source are groups GrA to GrC in which Mc1 to Mc4 and their own devices are different (NO in step S109), the response control unit 46 The communication device is discarded and the process is terminated (step S110).

  In step S109, if the wireless communication devices Ma1 to Ma4,..., Mc1 to Mc4 of the transmission source are the same group GrA to GrC as the own device (when YES in step S109), the response control unit 46 has the same sequence number. It is checked whether the wireless communication of the command has been received from the management device KS (step S111).

  If the wireless communication of the command of the same sequence number has been received in step S111 (when YES in step S111), the response control unit 46 sets a response unnecessary flag for the same sequence number and ends the processing ( Step S112).

  If the wireless communication of the command having the same sequence number has not been received in step S111 (NO in step S111), the response control unit 46 discards the wireless communication device and ends the process (step S110). ).

Accordingly, the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 can prevent performing unnecessary wireless communication, reduce the number of wireless communication, and suppress radio wave interference.
<When sending a response that includes a command included in wireless communication>
When the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 receive the unresponsive wireless communication addressed to the own device or the own group GrA to GrC, the wireless communication devices transmit the response wireless communication. Information related to wireless communication instructions may be incorporated.

  That is, as shown in FIG. 11, the management device KS performs a command wireless communication to the group GrA, and the wireless communication reaches at least the wireless communication device Ma4 but reaches the wireless communication device Ma1. Suppose that it was not. This command wireless communication is, for example, wireless communication with the group Gra as the destination, as shown in FIG.

  In this case, the wireless communication device Ma4 that has received the command wireless communication transmits the response wireless communication if the other wireless communication devices Ma1 to Ma3 of the group GrA have not transmitted the response wireless communication to the command. .

  At this time, as shown in FIG. 12B, the wireless communication device Ma4 transmits wireless communication (response data) of the response with the content of the wireless communication of the command from the management device KS added (embedded) as it is. To do. In FIG. 12B, the command wireless communication sequence number (“01”) is different from the response wireless communication sequence number (“02”). In this case, the response sequence number is The sequence numbers may be different or the same. This is because the instruction sequence number is included in the contents of the incorporated instruction.

  As shown in FIG. 11, the wireless communication device Ma1 that has not received the wireless communication of the command from the management device KS receives the wireless communication of the response transmitted by the wireless communication device Ma4.

  Upon receiving the response wireless communication transmitted from the wireless communication device Ma4, the wireless communication device Ma1 acquires the command incorporated in the response wireless communication and executes the command.

  That is, when the wireless communication device Ma1 receives the wireless communication of the response transmitted by the wireless communication device Ma4, the wireless communication device Ma1 executes the wireless communication process as shown in FIG. In FIG. 13, the same processing steps as those in FIG. 10 are given the same step numbers, and the description thereof is omitted or simplified.

  When receiving the wireless communication, the wireless communication device Ma1 checks whether it is addressed to the management device KS (step S101), and when not addressed to the management device KS, performs the same processing as above (steps S102 to S108).

  In step S101, if it is destined for the management device KS, the response determination unit 45 of the wireless communication device Ma1 has the wireless communication devices Ma1 to Ma4,... Is checked (step S109).

  In step S109, if the wireless communication devices Ma1 to Ma4, that is, the transmission source wireless communication devices Ma1 to Ma4 are different groups GrA to GrC, the response control unit 46 discards the wireless communication device and performs processing. The process ends (step S110).

  In step S109, if the source wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 are in the same group GrA to GrC, the response control unit 46 manages the wireless communication of the command with the same sequence number as the management device KS. It is checked whether it has been received from (step S201).

  Here, the content of the check process in step S201 is the same as in FIG. 10, but the processing method based on the check result is different.

  That is, if the wireless communication of the command with the same sequence number has been received in step S201 (when YES in step S201), the response control unit 46 sets a response unnecessary flag for the same sequence number and ends the processing. (Step S112). The processing in step S112 is the same as that in FIG.

  In step S201, if the wireless communication of the command with the same sequence number is not received (NO in step S201), the response control unit 46 sends the command incorporated in the wireless communication of the response to the wireless communication device Ma1. The wireless communication process is terminated (step S104).

  11 to 13, the transmission of the command from the management apparatus KS to the group GrA has been described, but the same applies to the transmission of commands to the other groups GrB and GrC.

Accordingly, the wireless communication devices Ma1 to Ma4,..., Mc1 to Mc4 that have not received the command can execute the command based on the command incorporated in the response. As a result, the operability and operational efficiency of the wireless communication system 1 can be improved while reducing the number of wireless communications and suppressing radio wave interference.
<When sending a response to an embedded response and executing the command>
When the command is incorporated in the response, the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 that have executed the command based on the response send a response to the response to the management device KS as illustrated in FIGS. May be.

  That is, as shown in FIGS. 14 and 15, the management device KS performs command wireless communication to the group GrB, and the wireless communication reaches at least the wireless communication device Mb4. However, the wireless communication device Mb1 Suppose that it has not arrived. The wireless communication of this command is, for example, wireless communication with the group GrB as the destination as shown in FIG.

  In this case, as shown in FIGS. 14 and 17, the wireless communication device Mb4 that has received the command wireless communication has transmitted other wireless communication devices Mb1 to Mb3 of the group GrB that are responding to the command. Otherwise, a response wireless communication is transmitted.

  At this time, as shown in FIG. 16B, the wireless communication device Mb4 transmits the wireless communication (response data) of the response with the content of the wireless communication of the command from the management device KS added (embedded) as it is. To do. In FIG. 16B, the command wireless communication sequence number (“01”) is different from the response wireless communication sequence number (“02”). In this case, the response sequence number is It may be different from or the same as the sequence number because the sequence number of the instruction is included in the contents of the embedded instruction.

  As shown in FIGS. 14 and 18, the wireless communication device Mb1 that has not received the command wireless communication from the management device KS receives the wireless communication of the response transmitted by the wireless communication device Mb4 and manages the response to the response. Send to device KS. At this time, the wireless communication devices Mb2 to Mb4 discard the response wireless communication from the wireless communication device Mb1, as shown in FIG.

  When the wireless communication device Mb1 receives the wireless communication of the response transmitted by the wireless communication device Mb4, the wireless communication device Mb1 acquires a command embedded in the wireless communication of the response and transmits a response to the response. Execute.

  That is, when the wireless communication device Mb1 receives the wireless communication of the response transmitted by the wireless communication device Mb4, the wireless communication device Mb1 executes the wireless communication process as shown in FIG. In FIG. 19, the same processing steps as those in FIG. 10 are given the same step numbers, and the description thereof is omitted or simplified.

  When receiving the wireless communication, the wireless communication device Mb1 checks whether it is addressed to the management device KS (step S101), and when not addressed to the management device KS, performs the same processing as above (steps S102 to S108).

  In step S101, if it is addressed to the management device KS, the response determination unit 45 of the wireless communication device Mb1 indicates that the wireless communication devices Ma1 to Ma4 to Mc4 of the transmission source are the same groups GrA to GrC as the own device. Is checked (step S109).

  In step S109, if the wireless communication devices Ma1 to Ma4, that is, the transmission source wireless communication devices Ma1 to Ma4 are different groups GrA to GrC, the response control unit 46 discards the wireless communication device and performs processing. The process ends (step S110).

  In step S109, if the source wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 are in the same group GrA to GrC, the response control unit 46 manages the wireless communication of the command with the same sequence number as the management device KS. It is checked whether it has been received from (step S211).

  Here, the content of the check processing in step S211 is the same as that in FIG. 10, but the processing method according to the check result is different.

  That is, if the wireless communication of the command with the same sequence number has been received in step S211 (YES in step S211), the response control unit 46 sets a response unnecessary flag for the same sequence number and ends the processing. (Step S112). The processing in step S112 is the same as that in FIG.

  If the wireless communication of the command with the same sequence number is not received in step S211 (NO in step S211), the response control unit 46 sends the command incorporated in the wireless communication of the response to the wireless communication device Mb1. The wireless communication process is terminated (step S104).

  14 to 19, the transmission of the command from the management apparatus KS to the group GrB has been described, but the same applies to the transmission of commands to the other groups GrA and GrC.

Accordingly, the wireless communication devices Ma1 to Ma4,..., Mc1 to Mc4 that have not received the command can execute the command based on the command embedded in the response and transmit wireless communication in response to the response. can do. As a result, the operability and operational efficiency of the wireless communication system 1 can be improved while reducing the number of wireless communications and suppressing radio wave interference.
<For transferring a response with an embedded command>
In each of the above explanations, a response for which the device has already received a command is not sent, but may be transferred.

  That is, as shown in FIG. 20, the command wireless communication is transmitted from the management device KS to the group GrB (S1). The wireless communication of this command is data as shown in FIG. 21 (S1), for example. In FIG. 20, in order to simplify and clarify the description, it is assumed that the group GrB includes three wireless communication devices Mb1 to Mb3. In FIG. 20, S1 to S6 are wireless communication devices. Showing the order.

  Now, when only the wireless communication device Mb3 among the wireless communication devices Mb1 to Mb3 of the group GrB receives wireless communication from the management device KS, the wireless communication device Mb3 transmits a response incorporating a command to the management device KS. (S2). The response wireless communication incorporating this command is data as shown in FIG. 21 (S2). In other words, all of the wireless communication data (sequence number, destination, transmission source, command, data) of the command transmitted by the management device KS is incorporated. In addition, although the wireless communication of the response which each wireless communication apparatus Mb1-Mb3 transmits reaches to the adjacent wireless communication apparatuses Mb1-Mb3, the wireless communication apparatuses Mb1-Mb3 across the other wireless communication apparatuses Mb1-Mb3 Shall not reach.

  The wireless communication device Mb2 that has received the response wireless communication from the wireless communication device Mb3 transmits the response wireless communication incorporating the command (S3). The wireless communication of this response is data as shown in FIG. 21 (S3), for example.

  The wireless communication device Mb1 that has received the response wireless communication from the wireless communication device Mb2 transmits the response wireless communication incorporating the command (S4). The wireless communication of this response is data as shown in FIG. 21 (S4), and the data of the repeater is further incorporated, but the repeater data may not be incorporated. The wireless communication device Mb2 that has received the response wireless communication from the wireless communication device Mb1 transfers the response wireless communication to the wireless communication device Mb1 (S5). As shown in FIG. 21 (S5), this response transfer wireless communication does not include the command content, but the “sequence of transmission”, the “relay device”, and the command “sequence” transmitted by the management device KS. Number "is added. The wireless communication device Mb1 that has received the transferred wireless communication for response transfers the wireless communication for response to the management device KS (S6). The transferred wireless communication of the transferred wireless communication is data as shown in FIG. 21 (S6), and is different from the transferred wireless communication by the wireless communication device Mb2 only in the destination, and other data contents are as follows. The same.

  In the transfer of the wireless communication, if large size data is transmitted, the large size wireless communication is transmitted a plurality of times, which causes radio wave interference. Therefore, when performing the transfer, the wireless communication devices Mb1 to Mb3 transmit only the data defined by the communication protocol such as the sequence number and the command, and the value is determined by the protocol included in the data item described in FIG. General-purpose data for which is not defined may be excluded from transfer targets. In this way, it is possible to reduce the data volume of transfer and suppress radio wave interference.

  Further, in the transfer of wireless communication, for example, as shown in FIGS. 22 to 25, the wireless communication devices Ma1 to Ma4,..., Mc1 to Mc4 that have received the responses send responses to the responses to the source of the response. You may transmit to radio | wireless communication apparatus Ma1-Ma4, ..., Mc1-Mc4.

  That is, as shown in FIG. 22, the wireless communication devices Mb2 to Mb4 have received the wireless communication of the command transmitted from the management device KS to the group GrB, but the wireless communication device Mb1 has not been able to receive it. To do. As shown in FIG. 23, the wireless communication device Mb4 is assumed to have transmitted the wireless communication of the response incorporating the command to the management device KS the earliest among the wireless communication devices Mb2 to Mb4 that have been successfully received. In this case, the wireless communication devices Mb2 and Mb3 that have received the command wireless communication determine that the response to the command embedded wireless communication is unnecessary, and perform the command wireless communication without performing the response wireless communication. Execute. As shown in FIG. 24, the wireless communication device Mb1 that has not received the command wireless communication sends a response to the wireless communication of the response in which the command is embedded as a transmission source of the response in which the command is embedded. Send to Mb4. In this case, even if the wireless communication devices Mb2 and Mb3 receive the wireless communication of the response addressed to the wireless communication device Mb4, they are not addressed to the own device, and thus are discarded as shown in FIG.

  The wireless communication device Mb4 that has received the wireless communication in response to the response transfers the wireless communication in response to the management device KS as it is, as shown in FIG. In this case, even if the wireless communication devices Mb2 and Mb3 receive the forwarded wireless communication, they are not destined for the own device, and discard them as shown in FIG.

  Therefore, wireless communication in response to the response can be reduced, the number of wireless communications can be reduced, and radio wave interference can be suppressed.

  Then, the management device KS manages the response wireless communication paths as shown in FIG. 26, for example, in the management of the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4. That is, as shown in FIG. 26A, when the wireless communication devices Ma1 to Ma3 and Mb1 to Mb3 are managed separately in two groups GrA and GrB, the management device KS is shown in FIG. Such a route table Tb is generated and route management is performed. The route table Tb has items of a device ID, a group, and a route. When wireless communication in response is received from the wireless communication devices Ma1 to Ma3 and Mb1 to Mb3, necessary item values are registered in the route table Tb from the contents. . Now, as shown in FIG. 25 (a), when a direct response is received from the wireless communication devices Ma3 and Ma2, the device IDs (Ma3 and Ma2) and group GrA of the wireless communication devices Ma3 and Ma2 are registered and received directly. (In FIG. 26B, “direct”) is registered.

  When receiving a response from the wireless communication device Ma1 via the wireless communication device Ma2, the management device KS, as shown in FIG. 25 (b), the device ID, Ma1, group, GrA, route Then, Ma2 is registered. Further, for the wireless communication devices Mb1 to Mb3 of the group GrB, when receiving a direct response from the wireless communication device Mb3 as shown in FIG. 26 (a), the management device KS sets the device ID of the route table Tb to “Mb3” is registered in the group, GrB is registered in the route, and “Direct” is registered in the route. When the response from the wireless communication device Mb2 is received via the wireless communication device Mb3 as shown in FIG. 26 (a), the management device KS sets Mb2 for the device ID of the route table Tb, GrB for the group. , Mb3 is registered in the route. When the response from the wireless communication device Mb1 is received via the wireless communication devices Mb2 and Mb3 as shown in FIG. 26A, the management device KS assigns Mb1 to the device ID of the route table Tb as a group. And GrB and Mb2 → Mb3 are registered in the route.

  Therefore, the administrator of the wireless communication system 1 can know the radio wave conditions of wireless communication between the wireless communication devices Ma1 to Ma4, Mc1 to Mc4 and the management device KS by looking at the route table Tb. it can. As a result, the radio wave condition can be improved by changing the management device KS one by one, and the operation efficiency of the wireless communication system 1 can be improved.

  In each of the above explanations, the management device KS manages the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 by dividing them into three groups GrA to GrC in a row as shown in FIG. Explained the case. Management of the wireless communication devices Ma1 to Ma4,..., Mc1 to Mc4 is not limited to the method based on the above three groupings.

  For example, the management device KS may manage the wireless communication devices (reference numerals omitted) by grouping them as shown in FIG. Note that in FIG. 27, the provision of codes to the wireless communication device is omitted. That is, as shown in FIG. 27A, the management device KS associates two wireless communication devices arranged in the vertical direction with the groups GrA and GrB, respectively, and the vertical and horizontal directions with the groups GrC and GrD, respectively. Two wireless communication devices lined up in the direction may belong. As shown in FIG. 27B, the management device KS causes the management device KS to attach two wireless communication devices arranged in the vertical direction to the groups GrA and GrB, respectively, and to the group GrC in the vertical direction. And two wireless communication devices arranged in the horizontal direction. Then, the management device KS sets other wireless communication devices to have no affiliated group. Further, as shown in FIG. 27C, the management device KS includes four wireless communication devices arranged in the vertical direction as a group GrA, one upper right wireless communication device as a group GrB, and a lower right horizontal direction. The four wireless communication devices arranged in a group are defined as a group GrC. The management device KS leaves the other wireless communication devices as belonging groups. The grouping is not limited to the grouping method shown in FIGS.

  As described above, in the wireless communication system 1 according to the present embodiment, the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 perform wireless communication with each other, and are group-managed by the management device KS via the wireless communication. A wireless communication device, a communication unit (communication means) 41 that wirelessly communicates with the wireless communication devices Ma1 to Ma4, Mc1 to Mc4 or the management device KS, and a self group that identifies at least a self group to which the self device belongs When the identification information storage unit (identification information storage unit) 42 that stores identification information and the communication unit 41 receive wireless communication, it determines whether the wireless communication is addressed to the own group based on the own group identification information. If the wireless communication received by the communication type determination unit (communication type determination unit) 43 and the communication unit 41 is a wireless communication addressed to the own group, a response to the wireless communication is returned. Response transmission unit (response transmission means) 44 for transmitting the line communication to the communication unit 41, and the wireless communication received by the communication unit 41 are other wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 belonging to the own group. The response determination unit (response determination unit) 45 that determines whether the response is the transmitted wireless communication, and the wireless communication received by the communication unit 41 are performed by the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 of the own group. The response wireless communication includes a response control unit (response control unit) 46 that stops transmission of a response by the response transmission unit 44 to the wireless communication that is a response target of the wireless communication.

  Therefore, if other wireless communication devices Ma1 to Ma4,..., Mc1 to Mc4 of the same group are transmitting responses, even if the wireless communication that is the response target is received, the response wireless to the wireless communication is received. Transmission of communication can be stopped. As a result, the number of wireless communications can be reduced and radio wave interference can be suppressed.

  Further, in the wireless communication system 1 according to the present embodiment, the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 perform wireless communication with each other, and group management is performed by the management device KS via the wireless communication. A wireless communication method executed by a device, comprising: a communication processing step of wirelessly communicating with the wireless communication devices Ma1 to Ma4, Mc1 to Mc4 or the management device KS; and a self group that identifies at least a self group to which the self device belongs When the wireless communication is received in the identification information storage processing step for storing the identification information in the identification information storage unit 42 and the communication processing step, whether the wireless communication is addressed to the local group based on the local group identification information A communication type determination processing step to be determined, and the wireless communication received in the communication processing step is a wireless communication addressed to the own group. Response transmission processing step for transmitting wireless communication in response to communication in the communication processing step, and the wireless communication received in the communication processing step are other wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 belonging to the own group. The response determination processing step for determining whether the response is the wireless communication of the transmitted response, and the wireless communication received in the communication processing step are the wireless of the response by the wireless communication devices Ma1 to Ma4, Mc1 to Mc4 of the own group If it is communication, a wireless communication method including a response control processing step of stopping transmission of a response in the response transmission processing step with respect to the wireless communication that is a response target of the wireless communication is executed.

  Therefore, if other wireless communication devices Ma1 to Ma4,..., Mc1 to Mc4 of the same group are transmitting responses, even if the wireless communication that is the response target is received, the response wireless to the wireless communication is received. Transmission of communication can be stopped. As a result, the number of wireless communications can be reduced and radio wave interference can be suppressed.

  Furthermore, the wireless communication system 1 according to the present embodiment includes wireless communication devices Ma1 to Ma4,..., Mc1 to Mc4 that perform wireless communication with each other and are group-managed by the management device via the wireless communication. A self-group identification for identifying, in a computer, communication processing for wireless communication with the wireless communication devices Ma1 to Ma4, Mc1 to Mc4 or the management device KS, and at least the own group to which the own device belongs An identification information storage process for storing information in the identification information storage unit 42, and a communication for determining whether the wireless communication is addressed to the own group based on the own group identification information when the wireless communication is received in the communication process If the wireless communication received in the type determination processing and the communication processing is wireless communication addressed to the own group, wireless communication in response to the wireless communication is performed. Whether the response transmission process to be transmitted in the communication process and the wireless communication received in the communication process are wireless communications of responses transmitted by other wireless communication devices Ma1 to Ma4, Mc1 to Mc4 belonging to the own group Response determination processing to be determined and the wireless communication received in the communication processing are the wireless communication of the response by the wireless communication devices Ma1 to Ma4, Mc1 to Mc4 of the own group, the response target of the wireless communication And a response control process for stopping transmission of a response in the response transmission process for the wireless communication.

  Therefore, if other wireless communication devices Ma1 to Ma4,..., Mc1 to Mc4 of the same group are transmitting responses, even if the wireless communication that is the response target is received, the response wireless to the wireless communication is received. Transmission of communication can be stopped. As a result, the number of wireless communications can be reduced and radio wave interference can be suppressed.

  Further, in the wireless communication system 1 according to the present embodiment, the management device KS and the plurality of wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 communicate with each other wirelessly, and the management device KS transmits the wireless communication devices Ma1 to Ma4. A wireless communication system for managing Mc1 to Mc4 in groups, wherein the wireless communication devices Ma1 to Ma4, Mc1 to Mc4 are the wireless communication devices Ma1 to Ma4, to Mc1 to Mc4, or A communication unit (communication means) 41 that wirelessly communicates with the management device KS, an identification information storage unit (identification information storage unit) 42 that stores at least own group identification information that identifies the own group to which the own device belongs, and the communication unit 41 When receiving wireless communication, based on the own group identification information, a communication type determining unit (communication type determining unit) determines whether the destination of the wireless communication is addressed to the own group. Means) 43 and a response transmission unit (response transmission means) 44 for transmitting the wireless communication in response to the wireless communication to the communication unit 41 when the wireless communication received by the communication unit 41 is wireless communication addressed to the own group. And a response determination unit (response determination unit) that determines whether the wireless communication received by the communication unit 41 is the wireless communication of the response transmitted by the other wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 belonging to the own group 45) If the wireless communication received by the communication unit 41 is the wireless communication of the response by the wireless communication devices Ma1 to Ma4, Mc1 to Mc4 of the own group, the wireless communication is the response target. A response control unit (response control means) 46 that stops transmission of a response by the response transmission unit 44 for wireless communication, and the management device KS includes the wireless communication devices Ma1 to Ma4. Management communication unit (management communication means) 51 that performs wireless communication with Mc1 to Mc4, and communication control that causes the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 to transmit wireless communication including instructions to the management communication unit 51 Unit (communication control means) 52 and the wireless communication devices Ma1 to Ma4 based on responses from the wireless communication devices Ma1 to Ma4 and Mc1 to Mc4 that are transmission destinations of the wireless communication received by the management communication unit 51 And a management unit (management means) 53 for managing Ma4,..., Mc1 to Mc4.

  Therefore, if other wireless communication devices Ma1 to Ma4,..., Mc1 to Mc4 of the same group are transmitting responses, even if the wireless communication that is the response target is received, the response wireless to the wireless communication is received. Transmission of communication can be stopped. Further, based on this response, the management device KS can perform group management of the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4. As a result, the number of wireless communications can be reduced and radio wave interference can be suppressed. As a result, the number of wireless communications can be reduced to suppress radio wave interference, and the appropriateness of management of the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 by the management device KS can be improved.

  Furthermore, in the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 of the wireless communication system 1 of the present embodiment, the response transmission unit 44 transmits a response incorporating a command included in the wireless communication.

  Therefore, even if there are wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 that have not received the command wireless communication among the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 in the same group, the instruction is incorporated. An instruction can be executed based on the received response. As a result, it is possible to appropriately perform operation control of the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 while reducing the number of wireless communication and suppressing radio wave interference.

  In addition, the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 of the wireless communication system 1 of the present embodiment are configured such that the response transmission unit 44 receives the wireless communication received by the communication unit 41 in the response wireless communication. Yes, if the communication unit 41 has not received the wireless communication that is the object of the response, the wireless communication of a response to which information indicating that the response is a response to the response is added.

  Therefore, the management device KS can grasp how wireless communication is transmitted to the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 by receiving the response to which the information is added. As a result, it is possible to appropriately perform group management of the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 while reducing the number of wireless communication and suppressing radio wave interference.

  Furthermore, the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 of the wireless communication system 1 according to the present embodiment perform wireless communication of a response to which information indicating that it is a response to the response is added. Upon receiving from the other wireless communication devices Ma1 to Ma4, Mc1 to Mc4 of the own group, the wireless communication in response is sent to the other wireless communication devices Ma1 to Ma4, to Mc1 to Mc4 or the management device KS. Further, a transfer unit (transfer means) 47 for transferring the data to 41 is further provided.

  Therefore, the responses of the wireless communication devices Ma1 to Ma4,..., Mc1 to Mc4 that could not directly receive the commanded wireless communication can be reliably transferred to the management device KS, and the wireless communication devices Ma1 to Ma4,. It is possible to reliably grasp how wireless communication is transmitted to Mc4. As a result, it is possible to appropriately perform group management of the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 while reducing the number of wireless communication and suppressing radio wave interference.

The apparatus further includes an identification information adding unit (identification information adding means) 48 for adding the device identification information to the wireless communication of the response transmitted by the response transmission unit 44 or the transfer unit 47.

  Therefore, the management device KS can more reliably grasp how the wireless communication is transmitted to the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 and how the response is transmitted. As a result, it is possible to appropriately perform group management of the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 while reducing the number of wireless communication and suppressing radio wave interference.

  Further, the wireless communication devices Ma1 to Ma4 to Mc1 to Mc4 of the wireless communication system 1 of the present embodiment are defined by the protocol that the response transmission unit 44 uses for the wireless communication, the command to be incorporated in the response. Express using only information.

  Therefore, the data capacity of wireless communication can be reduced, and radio wave interference can be further suppressed.
