It would be convenient if the above-mentioned transmitter functions could be realized by terminals such as smartphones. However, in this case, it is necessary to enable the terminal to transmit a control signal including an identifier assigned to the transmitter.

An object of the present invention is to enable smooth transmission of a control signal including an identifier by using a terminal different from the transmitter.

In home automation, a repeater that relays a control signal from a transmitter to a receiver may be used. The inventors have found a method for solving the above problems by using a repeater having a novel configuration.

The repeater according to one aspect of the present invention is a repeater that wirelessly relays a control signal for controlling a controlled device to a receiver, and stores an identifier assigned to the repeater and registered in the receiver. A storage unit, an input unit that receives a communication signal for controlling a controlled device from the terminal, and a signal based on the communication signal from the terminal received by the input unit, which are stored in the storage unit. It includes an output unit that wirelessly transmits a signal generated so as to include an identifier to a receiver as a control signal.

In the above repeater, the storage unit stores an identifier assigned to the repeater and registered in the receiver. Then, based on the communication signal for controlling the controlled device from the terminal, the control signal generated so as to include the identifier stored in the storage unit is transmitted to the receiver. By using such a repeater function, a control signal including an identifier can be smoothly transmitted using a terminal.

The communication signal from the terminal includes information for designating the control content, and the repeater is a signal generation unit that generates a control signal based on the communication signal from the terminal and the identifier stored in the storage unit. The output unit may wirelessly transmit the control signal generated by the signal generation unit to the receiver. As a result, the repeater only receives the communication signal including the information for designating the control content, and the repeater generates the control signal and transmits it to the receiver. Therefore, the control signal including the identifier can be smoothly transmitted by using the terminal without acquiring the identifier on the terminal side.

The storage unit stores a plurality of identifiers, the communication signal from the terminal includes index information for designating a desired identifier among the plurality of identifiers, and the signal generation unit is designated by the index information. A control signal may be generated using an identifier. As a result, the repeater only receives the communication signal including the index information, and the repeater generates a control signal using the identifier specified by the index information and transmits the control signal to the receiver. Therefore, the control signal including the identifier can be smoothly transmitted by using the terminal without acquiring the identifier specified by the index information on the terminal side.

The repeater further includes another input unit that receives a control signal for controlling the controlled device from a transmitter different from the terminal, and the transmitter unit wirelessly transmits the control signal received by the other input unit to the receiver. You may send it with. As a result, the signal from the dedicated transmitter capable of transmitting the control signal can be wirelessly relayed to the receiver.

The repeater according to one aspect of the present invention is a repeater that wirelessly relays a control signal for controlling a controlled device to a receiver, and stores an identifier assigned to the repeater and registered in the receiver. The storage unit, the input unit that receives the communication signal for controlling the controlled device from the terminal, and the signal based on the communication signal from the terminal received by the input unit are wirelessly transmitted to the receiver as a control signal. The input unit is a communication unit that performs bidirectional communication with the terminal, and in response to a request from the terminal, transmits an identifier stored in the storage unit to the terminal, and uses the communication signal as a communication signal. Contains the identifier. In this repeater as well, the storage unit stores an identifier assigned to the repeater and registered in the receiver. Here, in this relay device, the identifier stored in the storage unit is transmitted to the terminal in response to the request from the terminal. In addition, the communication signal from the terminal includes an identifier. Since the communication signal for controlling the controlled device from the terminal includes the identifier in this way, the signal based on the communication signal can be transmitted to the receiver as a control signal. Even with such a repeater function, a control signal including an identifier can be smoothly transmitted using a terminal.

The input unit may accept the communication signal from the terminal via the access point. As a result, the repeater can receive the communication signal from the terminal by using the access point regardless of whether it is wired or wireless.

The protocol of the communication signal may be different from the protocol of the control signal. As a result, the control signal including the identifier can be smoothly transmitted by using a terminal that does not support the control signal protocol.

According to the present invention, a control signal including an identifier can be smoothly transmitted by using a terminal different from the transmitter.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same elements are designated by the same reference numerals, and duplicate description will be omitted.

FIG. 1 is a diagram showing a schematic configuration of a relay system 1. The relay system 1 is used for remote control of the controlled device 70, for example, in home automation. An example of a controlled device 70 is a switch for a shield such as a curtain, a blind, or a shutter.

The relay system 1 includes a transmitter 10, a repeater 20, and a receiver 30. The transmitter 10 wirelessly transmits a control signal for controlling the controlled device 70. The repeater 20 relays the control signal from the transmitter 10 to the receiver 30. The receiver 30 receives the control signal from the repeater 20 and executes the control of the controlled device 70 according to the control signal. The receiver 30 is electrically connected to, for example, a control element such as a motor provided in the controlled device 70, and the controlled device 70 can be controlled by sending a control signal to the control element. .. Details of the functions of the repeater 20 and the receiver 30 will be described later with reference to FIG.

In order to transmit the control signal using the transmitter 10, in the relay system 1, the receiver 30 stores (registers) the ID stored in the transmitter 10 that intends to transmit the control signal to the receiver 30 ( Pairing is done). The ID is an identifier for identifying the transmitter 10 in the relay system 1. The transmitter 10 transmits a signal including the assigned ID and the control command as the above-mentioned control signal to the receiver 30 via the repeater 20. The receiver 30 receives the control signal including the registered ID among the control signals sent from the repeater 20, and executes the control of the controlled device 70 according to the control command included in the control signal. In this way, control of the controlled device using the transmitter 10 is realized.

Further, in the relay system 1, even if an element different from that of the transmitter 10 is used, a control signal including an ID assigned to the repeater in advance can be transmitted to realize control of the controlled device 70. As an element different from the transmitter 10, in the present embodiment, the terminal 40 will be described as an example. An example of the terminal 40 is a mobile terminal such as a smartphone.

In the relay system 1, the repeater 20 is configured to be able to communicate with the terminal 40. In the example shown in FIG. 1, the relay system 1 further includes an AP (access point) 50 and a communication line 60. The AP50 is a wireless access point for performing short-range wireless communication using Wi-Fi (registered trademark), Bluetooth (registered trademark), or the like. The communication line 60 connects the repeater 20 and the AP 50. The communication line 60 connects the repeater 20 and the AP 50 via a LAN (for example, Ethernet®).

The number of repeaters 20 and receivers 30 included in the relay system 1 is not limited to the example shown in FIG. When there are a plurality of repeaters 20, each repeater 20 is connected by a communication line 60. The terminal 40 communicates with each repeater 20 via the AP 50 and the communication line 60. Each repeater 20 has, for example, a serial number (S / N), and the terminal 40 can distinguish each repeater 20 by S / N.

FIG. 2 is a functional block diagram of the repeater 20 and the receiver 30. First, the repeater 20 will be described, and then the receiver 30 will be described.

The repeater 20 includes a first input unit 21, a second input unit 22, a storage unit 23, a signal generation unit 24, and an output unit 25.

The first input unit 21 is a portion that receives a control signal from the transmitter 10. The control signal is, for example, a signal based on a proprietary protocol using the 2.4 GHz band. For example, a low-speed signal using FSK modulation having a bandwidth of about several kHz to several hundred kHz may be used. By using a signal based on such a unique protocol as a control signal, for example, as compared with the case where a signal compliant with the Wif-Fi communication standard or a signal compliant with the Bluetooth communication standard is used as a control signal, the signals can be used as control signals. Coexistence can be enhanced and the communication distance can be lengthened.

The second input unit 22 is a part that receives a communication signal from the terminal 40. More specifically, the communication signal from the terminal 40 is received by the second input unit 22 via the AP 50 and the communication line 60. The communication signal between the terminal 40 and the AP 50 may be a signal conforming to the Wi-Fi communication standard as described above, and is a signal based on a protocol different from the original protocol of the control signal. In this case, the communication signal is a high-speed signal using DSSS, OFDM, etc., whose bandwidth is wider than the bandwidth of the control signal described above. Since the repeater 20 communicates with the terminal 40 via the AP 50 (FIG. 1), the second input unit 22 also functions as a communication unit that performs bidirectional communication with the terminal 40. Regarding the communication between the AP 50 and the second input unit 22 of the repeater 20, the signal on the communication line 60 is, for example, a signal compliant with the LAN communication standard, and is a signal compliant with the above-mentioned Wi-Fi communication standard. Although different, such signals on the communication line 60 may also be included in the communication signals herein.

The storage unit 23 is a portion that stores the ID registered in the receiver 30. Specifically, the storage unit 23 stores an ID assigned in advance in the manufacturing process of the repeater 20. A plurality of IDs may be stored in one repeater 20. The storage unit 23 can store the ID in the form of a list.

FIG. 3 is an example of a list stored in the storage unit 23. In this example, the list 23a stores 21 types of "IDs" (ID1 to ID21). In the list 23a, the "index" and the "ID" are associated with each other. The indexes are represented by numbers 1 to 21 in order from the top of the list 23a, and are used to specify the ID of the repeater 20 stored in the receiver 30.

Returning to FIG. 2 again, the signal generation unit 24 is a part that generates a control signal for transmission (relay) from the repeater 20 to the receiver 30. The signal generation unit 24 generates the control signal when the first input unit 21 receives the control signal from the transmitter 10 and when the second input unit 22 controls the controlled device 70 from the terminal 40. It is different from the case where the signal is received. When the first input unit 21 receives the control signal from the transmitter 10, the signal generation unit 24 reproduces the control signal by performing demodulation processing and modulation processing on the control signal. On the other hand, when the second input unit 22 receives the communication signal from the terminal 40, the signal generation unit 24 generates a control signal based on the communication signal. The latter case will be described in detail below.

The communication signal for controlling the controlled device from the terminal 40 includes the control content (for example, opening or closing the shield) of the controlled device 70. Further, as described above, a plurality of IDs may be stored in the storage unit 23. In that case, the control signal may also include index information for designating a desired ID among the plurality of IDs. The index information may be any of the numerical values 1 to 21 as shown in FIG. The signal generation unit 24 generates a control signal so as to include an ID stored in the storage unit 23 and a control command (described later with reference to FIG. 4) corresponding to the control content included in the above-mentioned communication signal. To do. When the communication signal includes index information, the control signal is generated so as to include the ID (FIG. 3) corresponding to the index information among the IDs stored in the storage unit 23.

FIG. 4 is a diagram showing a configuration example of a communication signal and a control signal. The communication signal for controlling the controlled device from the terminal 40 includes an "address", an "index", and a "control content" as shown in FIG. 4A. The address is the address of the repeater 20 (for example, the IP address in the case of LAN or WiFi) in the network configured by the communication line 60. On the other hand, the control signal generated by the signal generation unit 24 includes an "ID" and a "control command" as shown in FIG. 4B. The control command is a command for causing the receiver 30 to execute control related to the control content. For example, a command list in which control contents and control commands are associated with each other is stored in advance in the storage unit 23, and the signal generation unit 24 generates a control signal including a control command by referring to the command list. Can be done. The control content may be the control command itself, in which case the above command list is unnecessary. The control signal from the transmitter 10 received by the first input unit 21 (FIG. 2) may have the same configuration as that of FIG. 4 (b).

Returning to FIG. 2 again, the output unit 25 is a portion that wirelessly transmits the control signal generated by the signal generation unit 24 to the receiver 30. The control signal to be transmitted is a signal based on the same protocol as the control signal from the transmitter 10.

Next, the receiver 30 will be described. The receiver 30 includes a receiving unit 31, a storage unit 32, a collating unit 33, and a device control unit 34. The receiving unit 31 is a portion that receives a control signal from the repeater 20. The storage unit 32 is a part that stores the ID registered in the receiver 30 described above. The storage unit 32 is, for example, a non-volatile memory. The storage unit 32 may store a plurality of IDs. The procedure for storing the ID in the storage unit 32 will be described later with reference to FIG. The collating unit 33 is a portion that collates the ID included in the control signal received by the receiving unit 31 with the ID stored in the storage unit 32. When the ID included in the control signal matches the ID stored in the storage unit 32 (when a plurality of IDs exist in the storage unit 32, it matches any of the IDs), the device control unit 34 sends the control signal. Control of the controlled device 70 (for example, opening / closing control of a shield) is executed according to the control command included in.

Next, an example of the processing executed in the relay system 1 will be described with reference to FIGS. 5 to 7.

FIG. 5 is a sequence diagram showing an example of processing executed when the terminal 40 searches for the repeater 20 and confirms its existence.

At the terminal 40, a repeater search instruction is given (step S1). The repeater search instruction may be given by a user operation, or may be given periodically at a predetermined cycle. When the repeater search instruction is given at the terminal 40, the repeater search signal is transmitted to the repeater 20 (step S2). The transmission of the repeater search signal may be performed by transmitting a broadcast signal. The repeater search signal may be a signal having the same protocol as the communication signal described above.

The repeater 20 that has received the repeater search signal from the terminal 40 responds to the terminal 40 with the information of its own station (step S3). The reception of the repeater search signal and the response of the information of the own station are executed, for example, by the second input unit 22 transmitting the response signal to the terminal 40. When there are a plurality of repeaters 20 capable of communicating with the terminal 40, each of the plurality of repeaters 20 responds to the terminal 40 with the information of its own station. In the example shown in FIG. 5, the S / N and address of the repeater 20 are transmitted to the terminal 40 as information of the own station (solid arrow in step S3). When a plurality of repeaters 20 are present, the other repeaters 20 similarly respond to the terminal 40 with the information of their own station (dashed line arrow in step S3).

The terminal 40 acquires the S / N and the address from the repeater 20 (step S4), and creates a list of repeaters capable of communicating with the terminal 40 (step S5). The list is created, for example, by associating the S / N and address of each repeater.

As described above, the terminal 40 can acquire the S / N for distinguishing the repeaters 20 capable of communicating and the addresses required for communication with the repeaters 20. The terminal 40 may be configured to perform the above processing at any time or on a regular basis. As a result, the power of the repeater 20 is cut off, a failure occurs, the network between the terminal 40 and the repeater 20 is unstable, the connection is disconnected, and the address (IP address, etc.) of the repeater 20 in the LAN is changed. It is possible to respond to various environmental changes.

FIG. 6 is a sequence diagram showing an example of processing executed when pairing the terminal 40 and the receiver 30.

A pairing instruction is given at the receiver 30 (step S11). For example, the receiver 30 is set to the pairing mode by the user operating an operation button provided on the receiver 30. Further, the terminal 40 is also instructed to pair by a user operation or the like, and the terminal 40 is also set to the pairing mode (step S12).

When the pairing instruction is given at the terminal 40, the pairing command is transmitted from the terminal 40 to the repeater 20 (step S13). The pairing command from the terminal 40 to the repeater 20 may be transmitted using a signal having the same protocol as the communication signal described above. The pairing command includes information indicating an ID. In the example shown in FIG. 7, the pairing command includes an index (FIG. 3). When the storage unit 23 of the repeater 20 stores a plurality of IDs, the pairing command includes, for example, an index indicating a desired ID selected by a user operation of the terminal 40.

The repeater 20 replaces the index included in the pairing command transmitted from the terminal 40 with the ID corresponding to the index, and transmits (transfers) to the receiver 30 (step S14). The replacement process is executed, for example, by the signal generation unit 24. The pairing command transmitted from the repeater 20 to the receiver 30 may be transmitted as a kind of control command.

When the receiver 30 receives the pairing command from the repeater 20, the receiver 30 stores and holds the ID included in the pairing command in the storage unit 32, and completes the pairing mode (step S15). In this way, the ID is registered in the receiver 30.

After the transmission of the pairing command to the receiver 30 is completed, the repeater 20 responds (ACK) that the command from the terminal 40 has been accepted (step S16). The response of ACK is executed by, for example, the second input unit 22.

The terminal 40 receives the ACK from the repeater 20 and completes the pairing instruction (step S17). In this way, the ID is assigned to the terminal 40.

As described above, the ID can be assigned to the terminal 40 (step S17), the ID can be registered in the receiver 30 (step S15), and pairing can be performed. The pairing may be performed at least once before the terminal 40 controls the controlled device 70 (at the time of device installation). In the example of FIG. 6, it is assumed that the communication between the repeater 20 and the receiver 30 is unidirectional communication (repeater 20 → receiver 30), and in the above processing, the terminal 40 is reached. The transmission of ACK is performed by the repeater 20 instead of the receiver 30 (step S16). When the communication between the repeater 20 and the receiver 30 is bidirectional communication, the ACK to the terminal 40 may be transmitted from the receiver 30.

FIG. 7 is a sequence diagram showing an example of processing executed when the terminal 40 controls the controlled device 70.

A control instruction is given at the terminal 40 (step S21). For example, a controlled device 70 to be controlled and a control content are specified by a user operation. The method of designating the controlled device 70 and the control content by user operation is not particularly limited. For example, in the terminal 40, the name of each controlled device 70 and the type of control (opening or closing the shield, etc.) are selected by the user. It is advisable to display a screen for displaying. The name of each controlled device 70 is associated with an index for designating the ID selected at the time of pairing. When a control instruction is given at the terminal 40, a communication signal for controlling the controlled device 70 is transmitted to the repeater 20 (step S22). This communication signal includes an address for specifying the address of the repeater 20, an index for designating an ID, and control contents, as described above with reference to FIG.

In the repeater 20, a control signal is generated based on the communication signal from the terminal 40 and transmitted to the receiver 30 (step S23). The communication signal is received by the second input unit 22. The control signal is generated by the signal generation unit 24. This control signal includes an ID and a control command, as previously described with reference to FIG.

In the receiver 30, when the ID included in the control signal matches the ID stored in the storage unit 32 in the previous step S15 (FIG. 6), the controlled device 70 is controlled according to the control signal from the repeater 20. Is executed (step S24). Whether or not the IDs match is executed by the collating unit 33. The control of the controlled device 70 is executed by the device control unit 34.

After the transmission of the control signal is completed, the repeater 20 responds (ACK) that the communication signal from the terminal 40 has been received (step S25). The ACK is transmitted by the second input unit 22.

The terminal 40 receives the ACK from the repeater 20 and completes the control instruction (step S26).

As described above, the control of the controlled device using the terminal 40 is realized.

In the relay system 1 (FIG. 1) described above, the repeater 20 can also relay the control signal from the transmitter 10 to the receiver 30, but such a configuration is provided. A non-relay system is also conceivable. For example, the relay system 1A shown in FIG. 8 is different from the relay system 1 (FIG. 1) in that the transmitter 10 is not included and the repeater 20A is included instead of the repeater 20 (FIG. 1). To do. Since the other parts of the relay system 1A are the same as the corresponding parts of the relay system 1, the description thereof will be omitted. As shown in FIG. 9, the repeater 20A differs from the repeater 20 (FIG. 2) in that it does not include the first input unit 21 (FIG. 2). Since the other parts of the repeater 20A are the same as the corresponding parts of the repeater 20, the description thereof will be omitted. Since the repeater 20A does not include the first input unit 21, the repeater 20A does not need to relay the control signal from the transmitter 10 to the receiver 30 unlike the repeater 20.

Conversely, the repeater 20 can also be described as follows. That is, the repeater 20 further includes a first input unit 21 that receives a control signal for controlling the controlled device 70 from a transmitter 10 different from the terminal 40 as compared with the repeater 20A. The first input unit 21 corresponds to an additional input unit (additional input unit) different from the second input unit 22. The output unit 25 of the repeater 20A wirelessly transmits (relays) the control signal received by the first input unit 21 to the receiver 30.

In the repeaters 20 and 20A described above, the storage unit 23 stores the IDs assigned to the repeaters 20 and 20A and registered in the receiver 30. Then, based on the communication signal from the terminal 40, the control signal generated so as to include the ID stored in the storage unit 23 is transmitted to the receiver 30 (step S23). By using the functions of the repeaters 20 and 20A, the control signal including the ID assigned to the repeaters 20 and 20A can be smoothly transmitted by using the terminal 40. Further, in the repeater 20A, it is not necessary to perform a process for relaying the control signal from the transmitter 10 to the receiver 30, so that the processing load is reduced accordingly. Since the element related to the relay process (first input unit 21) is not required, the size and cost can be reduced.

The communication signal from the terminal 40 includes information for designating the control content ((b) in FIG. 4), and the repeaters 20 and 20A are stored in the storage unit 23 together with the communication signal from the terminal 40. A signal generation unit 24 that generates a control signal based on the ID may be further provided, and the output unit 25 may wirelessly transmit the control signal generated by the signal generation unit 24 to the receiver 30. As a result, only the repeaters 20 and 20A receive the communication signal including the information for designating the control contents, and the repeaters 20 and 20A generate the control signal and transmit it to the receiver 30. Therefore, the control signal including the ID can be smoothly transmitted by using the terminal 40 without acquiring the ID on the terminal 40 side.

The storage unit 23 stores a plurality of IDs (FIG. 5), and the communication signal from the terminal 40 includes index information for designating a desired ID among the plurality of IDs (FIG. 4 (a). )), The signal generation unit 24 may generate a control signal using the ID specified by the index information. As a result, the repeaters 20 and 20A only receive the communication signal including the index information, and the repeaters 20 and 20A generate a control signal using the ID specified by the index information and transmit the control signal to the receiver 30. .. Therefore, the control signal including the ID can be smoothly transmitted by using the terminal 40 without acquiring the ID specified by the index information on the terminal 40 side.

The repeater 20 (FIG. 2) further includes a first input unit 21 that receives a control signal for controlling the controlled device 70 from a transmitter 10 different from the terminal 40 as compared with the repeater 20A (FIG. 9). The output unit 25 may transmit the control signal received by the first input unit 21 to the receiver 30. As a result, the signal from the dedicated transmitter 10 capable of transmitting the control signal can be wirelessly relayed to the receiver 30.

The second input unit 22 can receive the communication signal from the terminal 40 via the AP50. As a result, the repeater 20 can receive the communication signal from the terminal 40 by using the AP 50 regardless of whether it is wireless or wired.

The protocol (or modulation method) of the communication signal may be different from the protocol (or modulation method) of the control signal. Thereby, the control signal including the ID can be smoothly transmitted by using the terminal 40 which does not correspond to the protocol (or modulation method) of the control signal.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

In the above embodiment, an example has been described in which the communication signal transmitted from the terminal 40 to the repeaters 20 and 20A (hereinafter collectively referred to as the repeater 20) includes an index for designating an ID. On the other hand, the communication signal transmitted from the terminal 40 to the repeater 20 may be configured to include an ID instead of the index. In such a modification, for example, in step S3 (FIG. 5) described above, the repeater 20 also has an ID (for example, list 23a) stored in the storage unit 23 in response to a request from the terminal 40. Send to terminal 40. In step S13 (FIG. 6), the pairing command transmitted from the terminal 40 to the repeater 20 is configured to include an ID instead of an index. In step S22 (FIG. 7), the communication signal transmitted from the terminal 40 to the repeater 20 is configured to include an ID instead of the index. By having the terminal 40 acquire the ID in this way, it is possible to generate a signal including the ID on the terminal 40 side as a communication signal. In this case, since the ID is already included in the communication signal for controlling the controlled device 70 sent from the terminal 40 to the repeater 20, the repeater 20 as described above with reference to FIG. It is not necessary for the signal generation unit 24 to read the ID corresponding to the index information from the storage unit 23, and the processing load on the repeater 20 can be reduced accordingly. Further, when a plurality of repeaters 20 exist on the communication line 60, the ID of one repeater 20 can be transmitted via another repeater 20. Even if there are receivers 30 in the communication range of one repeater 20 that exceeds the number of IDs stored in the storage unit 23, they can be individually controlled.
