[0003] [Patent Document 1] Patent No. 5536293 Summary of the Invention [Problem to be solved by the invention]

[0004] For example, there are stations like Tokyo Station and Ikebukuro Station that have complex and extensive interiors. People who do not regularly use such stations may get lost in the building and take a long time to reach their destination. In particular, if they have business at a store inside the station, they will have to walk around searching for the complex premises. Also, GPS (Global Positioning System) may not be able to determine the floor level, so there is a risk that GPS maps will not work.

[0005] Patent Document 1 discloses a communication method for transmitting information from lighting. However, when light from multiple lighting overlaps, interference occurs, and there is a risk that appropriate information may not be provided to the user.

[Effects of the Invention]

[0008] According to the control system of the present disclosure, when a communication unit is paired with an information terminal, the communication unit transmits information to the information terminal based on the response speed, radio wave strength, or radio wave direction in wireless communication between the information terminal and the communication unit. The information includes at least one of the following: location information of the communication unit, store information for the area where the communication unit is installed, floor level information for the area where the communication unit is installed, and floor map information for the area where the communication unit is installed.

[0010] The control system according to each embodiment will be described with reference to the drawings. The same or corresponding components are designated by the same reference numerals, and repeated description may be omitted.

[0011] Embodiment 1 FIG. 1 is a diagram illustrating the configuration of a control system 100 according to a first embodiment. Control system 100 includes multiple lighting fixtures 1-1, 2-1, and 3-1. The multiple lighting fixtures 1-1, 2-1, and 3-1, which act as master units, are provided with communication units 20-1, 20-2, and 20-3, respectively. Communication unit 20-1 controls lighting slave units 1-2, 1-3 to 1-n. Communication unit 20-2 controls lighting slave units 2-2, 2-3 to 2-n. Communication unit 20-3 controls lighting slave units 3-2, 3-3 to 3-n.

[0012] A plurality of lighting fixtures 1-1, 2-1, and 3-1 equipped with communication units 20-1, 20-2, and 20-3 are installed along a user's path of movement. The path of movement may be, for example, a passageway within a building or facility. As will be described later, communication units 20-1, 20-2, and 20-3 communicate with an information terminal 40 carried by a user. Lighting slave units 1-2 to 1-n, 2-2 to 2-n, and 3-2 to 3-n are installed in stores adjacent to their corresponding communication units 20-1, 20-2, and 20-3, respectively.

[0013] Server 30 transmits store information for the area in which each communication unit is installed to each communication unit 20-1, 20-2, and 20-3 via communication network 81. Server 30 may transmit store information for store A in which lighting slave units 1-2 to 1-n controlled by communication unit 20-1 are installed to communication unit 20-1. Server 30 may transmit store information for store B in which lighting slave units 2-2 to 2-n controlled by communication unit 20-2 are installed to communication unit 20-2. Server 30 may transmit store information for store C in which lighting slave units 3-2 to 3-n controlled by communication unit 20-3 are installed to communication unit 20-3. Store information may include, for example, the closing time and opening time of the store.

[0014] Communication units 20-1, 20-2, and 20-3 store store information transmitted from server 30. Communication units 20-1, 20-2, and 20-3 respectively control the dimming of lighting slave units 1-2 to 1-n, 2-2 to 2-n, and 3-2 to 3-n in accordance with the store information. For example, each communication unit 20-1, 20-2, and 20-3 changes the illuminance of the corresponding lighting slave units 1-2 to 1-n, 2-2 to 2-n, and 3-2 to 3-n when the corresponding store is closing or opening. Note that communication units 20-1, 20-2, and 20-3 successively acquire the current time from server 30.

[0015] For example, server 30 transmits the closing time of store A, 19:00, to communication unit 20-1, sets the closing time of store B, 20:00, to communication unit 20-2, and transmits the closing time of store C, 20:30, to communication unit 20-3. This allows the illuminance of lighting slave units 1-2 to 1-n, 2-2 to 2-n, and 3-2 to 3-n in the store to be controlled at the appropriate times. Furthermore, communication units 20-1, 20-2, and 20-3 may reduce the illuminance at 19:00, the closing time, and then turn off the lights completely after a predetermined time has passed, for example, at 19:20.

[0016] The communications between the communication units 20-1, 20-2, and 20-3 and the lighting slave units 1-2 to 1-n, 2-2 to 2-n, and 3-2 to 3-n are, for example, serial communications 82.

[0017] 2 is a block diagram showing the configuration of the control system 100 according to the first embodiment. The server 30 stores, for example, location information of the communication units 20-1, 20-2, and 20-3, and the above-mentioned store information. Furthermore, the server 30 may store hierarchical information of the area in which the communication units 20-1, 20-2, and 20-3 are installed, and floor map information of the area in which the communication units 20-1, 20-2, and 20-3 are installed. The hierarchical information is, for example, information indicating on which floor the communication units 20-1, 20-2, and 20-3 are installed.

[0018] The server 30 transmits location information, store information, floor level information, and floor map information to each of the communication units 20-1, 20-2, and 20-3 via the communication network 81. The server 30 only needs to transmit at least one of these pieces of information to each of the communication units 20-1, 20-2, and 20-3.

[0019] 1 and 2, the location information of communication unit 20-1, store information of store A, hierarchical information of the area where communication unit 20-1 is installed, and floor map information of the area where communication unit 20-1 is installed are transmitted to communication unit 20-1. Also, the location information of communication unit 20-2, store information of store B, hierarchical information of the area where communication unit 20-2 is installed, and floor map information of the area where communication unit 20-2 is installed are transmitted to communication unit 20-2.

[0020] Furthermore, when the communication unit 20 is paired with the information terminal 40, it transmits information such as location information, store information, floor information, and floor map information acquired from the server 30 to the information terminal 40. The information terminal 40 is, for example, a smartphone or a tablet terminal.

[0021] There are three methods for pairing a communication unit 20 with an information terminal 40. The first method is to send a command from the information terminal 40 and communicate with the communication unit 20 that responds the fastest. The second method is to communicate with a communication unit 20 with strong radio wave intensity. The third method is to communicate using beamforming. In this embodiment, the first method will be described below.

[0022] Fig. 3 is a flowchart showing the operation of control system 100 pertaining to embodiment 1. Communication between communication unit 20-1 of lighting fixture 1-1, which is the master unit, and lighting slave units 1-2 to 1-n will be described using Fig. 3. The same applies to communication between communication unit 20-2 and lighting slave units 2-2 to 2-n, and communication between communication unit 20-3 and lighting slave units 3-2 to 3-n.

[0023] Under normal circumstances, lighting fixture 1-1 sends a lighting instruction to lighting slave units 1-2 to 1-n (step 1). At this time, communication unit 20-1 determines whether communication with user information terminal 40 is possible (step 10). Step 10 will be described later.

[0024] Next, the communication unit 20-1 determines whether it is closing time based on the store information acquired from the server 30 (step 2). When it is closing time, the communication unit 20-1 transmits a dimming instruction to the address of the lighting slave units 1-2 to 1-n of the closed store (step 3). The current time can be acquired from the server 30. This dimming instruction is, for example, an instruction to turn off the lights. The dimming instruction from the communication unit 20-1 to the lighting slave units 1-2 to 1-n is executed by serial communication (step 4).

[0025] Even when the communication unit 20-1 of the parent device is instructed to turn off the lights, it can communicate with the user's information terminal 40. In step 3, detailed control may be performed, for example, by reducing the illuminance to 50% at closing time of 19:00 and setting the illuminance to 0% at 19:20.

[0026] Thereafter, the communication unit 20-1 determines whether it is opening time or not based on the store information acquired from the server 30 (step 5). The lighting slave units 1-2 to 1-n are kept turned off until opening time (step 6). When opening time arrives, the communication unit 20-1 instructs the lighting slave units 1-2 to 1-n to turn on (step 1).

[0027] 4 and 5 are diagrams illustrating the pairing method according to the first embodiment. FIG. 4 shows an example in which command CM1 is transmitted from information terminal 40 to communication units 20-1 and 20-2. This command CM1 is composed of "lighting communication CM," "CM," and "information terminal identification address." As an example, let's say "lighting communication CM" is 99, "CM" for the pairing request is 01, and "CM" for canceling pairing is 02. If the "information terminal identification address" is, for example, A12345, then the pairing request command CM1 will be 9901A12345.

[0028] Upon receiving command CM1, communication units 20-1 and 20-2 send command CM2 back to the information terminal 40 that sent command CM1. This command CM2 is composed of an "information terminal communication CM," a "CM," and a "lighting identification address." As an example, let's say the "information terminal communication CM" is 98, the "CM" for pairing is 01, and the "CM" for data information is 02, 03, etc. Let's say the "lighting identification address" of communication unit 20-1 is A101, and the "lighting identification address" of communication unit 20-2 is A102, for example. In this case, the command CM2 from lighting fixture 1-1 is 9801A101, and the command CM2 from lighting fixture 2-1 is 9801A102.

[0029] Here, it is assumed that communication unit 20-2 responded first. Information terminal 40 determines that communication unit 20-2, which responded first, is the closest communication unit 20, and starts pairing with lighting fixture 2-1. In other words, of the multiple communication units 20-1, 20-2, and 20-3, the communication unit 20 with the fastest response speed is paired with information terminal 40. The paired communication unit 20 transmits information such as location information, store information, floor information, and floor map information to information terminal 40.

[0030] As shown in Fig. 5, lighting fixture 1-1 has an LED 1a as a light source, a transmitter 1b, and a receiver 1c. For example, transmitter 1b controls LED 1a in response to a signal received by receiver 1c from communication unit 20. The other lighting fixtures 2-1 and 3-1 have similar configurations. Furthermore, communication unit 20-1 has a signal receiver 20a, a data storage unit 20b, a data transmitter 20c, and a receiver 20d. The other communication units 20-2 and 20-3 have similar configurations.

[0031] The information terminal 40 transmits a command CM1 to the signal receiving unit 20a of the communication unit 20-1 via communication 83. The data transmitting unit 20c of the communication unit 20-1 responds with a command CM2 to the information terminal 40 via communication 84. The communications 83 and 84 are wireless communications such as Bluetooth (registered trademark). The communications 83 and 84 may be P2P (Peer to Peer) communications. If the communication unit 20-1 responds first among the multiple communication units 20-1, 20-2, and 20-3, the information terminal 40 and the communication unit 20-1 are paired.

[0032] The server 30 transmits information such as location information, store information, floor information, and floor map information via the communication network 81. The data storage unit 20b of the communication unit 20-1 stores the received information. The data storage unit 20b can be configured with a memory such as a nonvolatile memory. The data transmission unit 20c transmits the above information to the paired information terminal 40 via communication 84.

[0033] The data transmission unit 20c and the reception unit 20d communicate with the lighting slave units 1-2 to 1-n via serial communication .

[0034] Fig. 6 is a flowchart showing the operation of the control system according to the first embodiment. The operation during pairing will be described using Fig. 6. The operation described here corresponds to the operation in step 10 of Fig. 3. First, the user starts an app on information terminal 40 (step 11), and transmits command CM1 from information terminal 40 (step 12). If there is a lighting device with which communication is possible (Yes in step 13, No in step 16), the lighting device transmits command CM2 to information terminal 40 (step 17). This causes the lighting device and information terminal 40 to be paired (step 19).

[0035] If there are multiple lighting fixtures that can communicate (Yes in step 16), the lighting fixture that responded first (step 18) is paired with the information terminal 40 (step 19). If there are no lighting fixtures that can communicate (No in step 13), communication becomes impossible (step 14) and the pairing operation ends (step 15).

[0036] The paired lighting fixture transmits information such as location information, floor information, and floor map information to the information terminal 40 (step 20). If the cookie is valid (step 22), store information suitable for the user is selected, and the store information is transmitted from the lighting fixture to the information terminal 40 (step 24). That is, the lighting fixture extracts stores recommended for the user from the information acquired from the server 30 and transmits the extracted stores to the information terminal 40. The information transmitted to the information terminal 40 is displayed on the information terminal 40. The selection of store information suitable for the user may be performed by the server 30 or the like. The pairing is then canceled (step 25). If the cookie is not valid, the pairing is canceled at that point (step 23).

[0037] After the lighting fixture transmits command CM2 to information terminal 40 in step 18, the lighting fixture may create a list of nearby store information (step 21). This store information may be transmitted to information terminal 40.

[0038] 7 is a flowchart showing the overall operation of the control system 100 according to embodiment 1. In FIG. 7, an overall flowchart is shown that combines the operations of FIGS.

[0039] Next, the effects of this embodiment will be described. According to the control system 100 of this embodiment, when the communication unit 20 is paired with the information terminal 40, it transmits information including at least one of location information, store information, floor information, and floor map information to the information terminal 40. This makes it possible to provide the user with information corresponding to the location, area, or floor of the communication unit 20, even in a building with multiple floors and a complex structure, such as a large train station. In other words, the lighting fixture to be paired can be switched depending on the user's current location, and location information, etc., can be updated in real time. Therefore, appropriate information can be provided to the user. It can also be said that this embodiment provides a mapping system that can appropriately identify the user's location, even in a building with a complex structure.

[0040] Furthermore, the communication unit 20 is paired with the information terminal 40 based on the response speed in wireless communication between the communication unit 20 and the information terminal 40. This makes it possible to pair the appropriate communication unit 20 with the information terminal 40 even when there are multiple lighting fixtures. This prevents interference and ensures that information is provided to the user reliably.

[0041] Furthermore, since the information terminal 40 directly communicates with the lighting fixtures to obtain information, users can obtain information even in underground malls where radio waves are difficult to reach. Furthermore, since lighting fixtures are generally installed at short intervals, users can obtain highly accurate location information. Furthermore, since the control system 100 can be configured by adding a communication unit 20 to the lighting fixtures, the control system 100 can be easily realized without adding additional space. Note that the information terminal 40 and lighting fixtures may communicate via another device.

[0042] The control system 100 of this embodiment may be installed not only in train stations but also in shopping centers, supermarkets, etc. This allows users to check the sales areas. In addition, providing store information can also have an advertising effect.

[0043] The numbers of lighting fixtures 1-1, 2-1, 3-1 and lighting slave units 1-2 to 1-n, 2-2 to 2-n, 3-2 to 3-n are not limited to those described above. The number of lighting fixtures and lighting slave units provided in control system 100 may be one or more. Furthermore, lighting slave units may not be provided depending on the application. Furthermore, control system 100 may be provided with at least server 30 and communication unit 20. Communication unit 20 does not have to be installed in the lighting fixture.

[0044] Furthermore, the control device that transmits information including at least one of location information, store information, hierarchical information, and floor map information to the communication unit 20 is not limited to the server 30, but may be any device that can communicate with the communication unit 20.

[0045] The above-described modifications can be applied as appropriate to the control systems according to the following embodiments. Note that the control systems according to the following embodiments have many points in common with the first embodiment, so the following description will focus on the differences from the first embodiment.

[0046] Embodiment 2 In this embodiment, a method of communicating with a communication unit 20 with strong radio wave intensity will be described. FIG. 8 is an image diagram showing radio wave intensity according to the second embodiment. The radio wave intensity of lighting fixtures 1-1, 2-1, and 3-1, i.e., the radio wave intensity emitted by communication units 20-1, 20-2, and 20-3, varies depending on the location. In the example of FIG. 8, the radio wave intensity increases in the order of solid line, dotted line, dashed line, and dashed-dotted line. In this embodiment, the communication unit with the strongest radio wave intensity among the multiple communication units 20-1, 20-2, and 20-3 is paired with information terminal 40 and transmits information to information terminal 40. As a result, the lighting fixture with which information terminal 40 is paired changes depending on the location from which information terminal 40 starts communication.

[0047] FIG. 9 is a diagram illustrating a pairing method according to the second embodiment. Information terminal 40 initiates communication with communication units 20-1, 20-2, and 20-3 via communication 83. Communication 83 is, for example, wireless communication such as Bluetooth. Communication 83 may also be P2P communication. Information terminal 40 measures the radio wave intensity of communication 83 and pairs with the lighting fixture with the strongest radio wave intensity. When lighting fixture 1-1 is paired with information terminal 40, information is transmitted from data transmitter 20c of communication unit 20-1 to the information terminal via communication 83.

[0048] Fig. 10 is a flowchart showing the operation of the control system 100 according to the second embodiment. The operation during pairing will be described using Fig. 10. The operation described here corresponds to the operation in step 10 in Fig. 3. First, the user launches an app on the information terminal 40 (step 111) and starts Bluetooth communication (step 112). This causes the information terminal 40 to determine whether there is a lighting fixture that can be paired (step 113). If there is one lighting fixture that can be paired (No in step 116), that lighting fixture and the information terminal 40 are paired (step 117).

[0049] If there are multiple lighting devices that can be paired (Yes in step 116), the information terminal 40 acquires the average value of radio wave strength dBm over a predetermined period, such as two seconds (step 118), and pairs with the lighting device with the strongest radio wave strength (step 120). If the average values are the same (Yes in step 119), the information terminal 40 pairs with the lighting device with the highest peak value of radio wave strength (step 122). If the average value and the peak value are the same (Yes in step 121), the information terminal 40 pairs with a lighting device randomly (step 123). If there are no lighting devices that can communicate (No in step 113), communication is disabled (step 114), and the pairing operation ends (step 115).

[0050] The paired lighting fixture transmits information such as location information, floor information, and floor map information to the information terminal 40 (step 20). Steps 21 to 25 are the same as those in the first embodiment.

[0051] 11 is a flowchart showing the overall operation of the control system 100 according to embodiment 2. In this embodiment as well, the operations in FIGS. 3 and 10 can be combined.

[0052] Embodiment 3 In this embodiment, a method of communication using beamforming will be described. FIG. 12 is an image diagram illustrating beamforming according to a second embodiment. In this embodiment, multiple communication units 20-1, 20-2, and 20-3 provided in lighting fixtures 1-1, 2-1, and 3-1 are capable of wireless communication with information terminal 40 using directional radio waves. At this time, the radio waves received are switched depending on the position of information terminal 40. In this embodiment, a communication unit from among multiple communication units 20-1, 20-2, and 20-3 whose radio waves are received by information terminal 40 is paired with information terminal 40 and transmits information to information terminal 40. Therefore, the lighting fixture to be paired is switched depending on the position from which information terminal 40 starts communication. In other words, communication unit 20 is paired with information terminal 40 based on the direction of radio waves in wireless communication with information terminal 40.

[0053] 13 is a diagram illustrating a pairing method according to the third embodiment. Information terminal 40 initiates communication 83 such as Bluetooth. When information terminal 40 receives directional radio waves, it pairs with the lighting fixture that emitted the radio waves. When lighting fixture 1-1 is paired with information terminal 40, information is transmitted from data transmitter 20c of communication unit 20-1 to information terminal 40 via communication 83.

[0054] Fig. 14 is a flowchart showing the operation of the control system 100 according to the second embodiment. The operation during pairing will be described using Fig. 14. The operation described here corresponds to the operation in step 10 of Fig. 3. First, the user starts an app on the information terminal 40 (step 211), and switches to a reception mode for Bluetooth communication or the like (step 212). This causes the information terminal 40 to determine whether or not a radio wave has been received (step 213). If a radio wave has been received (Yes in step 213), the lighting fixture that is the source of the radio wave and the information terminal 40 are paired (step 215).

[0055] If no radio wave is received (No in step 213), communication is disabled (step 214), and the reception mode (S212) continues.

[0056] The paired lighting fixture transmits information such as location information, floor information, and floor map information to the information terminal 40 (step 20). Steps 22 to 25 are the same as those in the first embodiment.

[0057] 15 is a flowchart showing the overall operation of the control system 100 according to embodiment 2. In this embodiment as well, the operations in FIGS. 3 and 14 can be combined.

[0058] As described above, the communication unit 20 may be paired with the information terminal 40 based on the response speed, radio wave strength, or radio wave direction in wireless communication with the information terminal 40. Either method can be used to pair the communication unit 20 and the information terminal 40 appropriately when there are multiple lighting fixtures. This prevents interference and ensures that appropriate information is provided to the user. The control system 100 may be able to switch between the pairing methods.

[0059] The technical features described in this embodiment may be used in appropriate combination.
