(First embodiment)
Hereinafter, a remote controller for a water heater according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a data acquisition system 1 that acquires data from a water heater remote control 10 according to the first embodiment. The data acquisition system 1 includes a hot water supply system 2. The hot water supply system 2 heats water and supplies hot water to a predetermined location, and a remote controller for hot water heater that remotely operates the water heater main body 3. 10. The water heater remote control 10 includes an operation unit 12 for remotely operating the water heater main body 3 and a display unit 13 for displaying commands and various information input by the operation unit 12. Below, the structure of the remote controller 10 for hot water heaters is demonstrated in detail, and the method to acquire data from the remote controller 10 for hot water heaters is demonstrated after that.

  2 and 3 schematically show the appearance of the remote controller 10 for a water heater according to the first embodiment. 2 (A) and 3 (A) are schematic front views of the water heater remote control 10, and FIGS. 2 (B) and 3 (B) are schematic left side views of the water heater remote control 10. FIG. The water heater remote control 10 is installed on a wall surface W of a bathroom or kitchen, for example. A remote controller 10 for a water heater according to the present embodiment includes a substantially rectangular parallelepiped casing 11 and a lid 14 that covers a part of a casing main surface portion 11a that is a main surface portion of the casing 11 that is not in contact with the wall surface W. have.

  In the main surface portion upper portion 11b of the main surface portion 11a of the housing that is not covered with the lid body 14, a display unit 13 configured by a display panel or the like and a plurality of operation switches 12a to 12l configuring the operation unit 12 are provided. Main switches 12a to 12e, which are a part of the main switches, are arranged. Of the plurality of operation switches 12a to 12l, additional switches 12f to 12l that are the remaining ones of the plurality of operation switches 12a to 12l are disposed on the main surface portion lower portion 11c that is a portion covered with the lid body 14 in the housing main surface portion 11a (see FIG. 3 (A)). The additional switches 12f to 12l are switches that are used less frequently than the main switches 12a to 12e.

  Usually, the remote controller 10 for water heater is provided with an operation switch (for example, reference numeral 12a). Each time the operation switch 12a is pressed, the operation switch 12a switches between an “operation on state” and an “operation off state”. Here, the “operation on state” means a hot water supply heating operation when various conditions are met, such as when a hot water tap (not shown) is opened and the amount of water flow per unit time of the hot water supply passage exceeds a predetermined amount. The state which becomes possible is said, and the “operation off state” refers to a state where the hot water supply heating operation is not performed even if the above various conditions are met.

  The lid body 14 is rotatably attached to the housing 11 via a hinge portion 15 provided at the lower end of the housing main surface portion 11a of the housing 11. The lid 14 can be rotated with respect to the housing 11 to operate in a closed state covering the additional switches 12f to 12l as shown in FIG. 2 and the additional switches 12f to 12l as shown in FIG. Transition between the open state to make it a proper state. The lid body 14 is provided with a locking portion 16 that locks with the housing 11 so that the closed state is maintained. Note that, in the water heater remote control 10, the lid body 14 is normally closed except in a special case such as when the user operates the additional switches 12f to 12l.

  The casing 11 is provided with an NFC (Near Field Communication) reader / writer 31, while the lid 14 is provided with an NFC tag 32.

  The NFC reader / writer 31 is built in the housing 11, and is disposed between the main surface lower part 11 c covered with the lid body 14 and the wall surface W.

  As shown in FIG. 3A, the NFC tag 32 is disposed so as to be close to the NFC reader / writer 31 when the lid 14 is in the closed state. The NFC tag 32 is attached to one main surface of the two main surfaces of the lid body 14, which faces the main surface portion lower part 11 c when the lid body 14 is in the closed state. Further, a mark 33 is attached to a portion corresponding to the back side of the NFC tag 32 on the other main surface of the two main surfaces of the lid 14 so that the position of the NFC tag 32 can be seen. The mark 33 is a mark indicating a position where an NFC terminal device 60 described later is held.

  When the lid 14 moves between the open state and the closed state, the position of the NFC tag 32 attached to the lid 14 is also changed accordingly. That is, the NFC tag 32 is positioned at the first position close to the NFC reader / writer 31 when the lid 14 is in the closed state as shown in FIG. The NFC tag 32 in the first position is close to the NFC reader / writer 31 within a range where NFC communication is possible. Further, the NFC tag 32 is positioned at a second position that is more distant from the NFC reader / writer 31 than when it is in the first position when the lid 14 is in the open state as shown in FIG. In this embodiment, the NFC tag 32 in the second position is located outside the range where NFC reader / writer 31 can communicate with NFC. However, the NFC tag 32 in the second position does not have to be located outside the range where NFC reader / writer 31 can communicate with NFC. For example, the second position is determined by bringing the NFC terminal device 60 close to one of the NFC tag 32 and the NFC reader / writer 31 in the second position, and the NFC terminal surely intended (the NFC terminal device 60 is moved closer). Any position where communication with the device 60 can be established. In this embodiment, the lid body 14 and the hinge portion 15 constitute a position changing mechanism of the present invention that changes the position of the NFC tag 32 with respect to the NFC reader / writer 31.

  The casing 11 is provided with a position detection unit 17 that detects whether or not the NFC tag 32 is in the first position, and a signal detected by the position detection unit 17 is sent to a remote control unit 40 described later. It is done. The position detection unit 17 is a known open / close detection switch that detects the open / close state of the lid body 14, for example.

  Returning to FIG. 1, the NFC reader / writer 31 is configured to perform P2P communication with the NFC terminal device 60 brought close to the NFC communicable range. The NFC reader / writer 31 transmits / receives data to / from the NFC terminal device 60 at, for example, 38400 bps by P2P communication.

  The NFC reader / writer 31 has a function of performing NFC communication with the NFC tag 32 within the NFC communicable range. In this embodiment, the NFC reader / writer 31 is configured to write abnormality information to the NFC tag 32 when, for example, an abnormality such as a failure occurs in the water heater body 3.

  The NFC reader / writer 31 has a memory function for storing operation information of the water heater body 3 and abnormality information relating to failures that have occurred so far. A part of the information stored in the NFC reader / writer 31 is sent to the NFC terminal device 60 or written to the NFC tag 32 as described above.

  The NFC reader / writer 31 becomes communicable when power is supplied from the remote controller 10 for hot water heater. As will be described later, the NFC reader / writer 31 can be switched between a “power-on state” and a “power-off state” under the control of the hot water heater remote controller 10 that is energized. Here, the “power-on state” refers to a state where power is supplied, and the “power-off state” refers to a state where power is not supplied. In addition, the NFC reader / writer 31 of this embodiment can communicate only when the power is supplied to the hot water supply remote controller 10. That is, the NFC reader / writer 31 is configured so that it cannot communicate with the NFC terminal device 60 when the water heater remote control 10 itself fails, for example, when the water heater remote control 10 is not energized.

  The NFC tag 32 has a function of communicating with the NFC terminal device 60 that is brought close to the NFC communicable range. The NFC tag 32 can be accessed regardless of whether or not power is supplied to the hot water heater remote control 10. That is, even if the hot water supply remote controller 10 breaks down and the power is turned off, data can be acquired from the NFC tag 32 using the NFC terminal device 60 or the like. Since the memory size of the NFC tag 32 is small, the NFC tag 32 stores only recent abnormality information having a high priority, for example.

  As described above, the water heater remote control 10 includes two NFC reader / writers (corresponding to the “first memory” of the present invention) 31 and NFC tags (corresponding to the “second memory” of the present invention) 32 having a memory function. Has memory. In this embodiment, these two memories are configured such that data acquired by the NFC terminal device 60 when they are accessed by the NFC terminal device 60 are different from each other. For example, when the NFC terminal device 60 is communicatively connected to the NFC reader / writer 31, the NFC terminal device 60 acquires data having a relatively large capacity such as operation information of the water heater main body 3. Further, when the NFC terminal apparatus 60 is connected to the NFC tag 32 for communication, the NFC terminal apparatus 60 acquires data having a high priority and a relatively small capacity related to a failure that has recently occurred. In FIG. 1, the NFC terminal device 60 is shown to communicate with both the NFC reader / writer 31 and the NFC tag 32. However, as will be described later, in actual data acquisition work, the NFC terminal device 60 communicates with either one of them. To do.

  FIG. 1 schematically shows functional blocks of a remote control unit 40 of the hot water supply remote controller 10. The remote control unit 40 includes a calculation unit such as a CPU that executes various calculation processes and a storage unit (not shown) such as a ROM and a RAM that store various programs or data. The remote control unit 40 includes a water heater control unit 41, a display control unit 42, and an access enable / disable switching unit 43. These functional units are constructed by combining hardware such as the CPU and software stored in the ROM and the like. Has been.

  The water heater controller 41 controls the water heater main body 3 by sending a command to the water heater main body 3 so as to perform an operation according to the operation of the operation unit 12. Further, the display control unit 42 controls the display unit 13 so that information according to the operation on the operation unit 12 is displayed.

  The access permission switching unit 43 (corresponding to the “switching unit” of the present invention) determines whether or not the NFC tag 32 is in the first position based on the signal sent from the position detection unit 17. The access permission switching unit 43 switches whether the NFC terminal device 60 can access the NFC reader / writer 31 according to the position of the NFC tag 32. Specifically, the access enable / disable switching unit 43 controls power supply to the NFC reader / writer 31 to switch between the power-on state and the power-off state of the NFC reader / writer 31. Thereby, as described above, the NFC reader / writer 31 is switched between a state where communication is possible and a state where communication is not possible.

  Thus, when the NFC tag 32 determines that the NFC tag 32 is in the first position, the access permission switching unit 43 switches the NFC reader / writer 31 so that the NFC terminal device 60 cannot access it, and the NFC tag 32 is in the second position. When it is determined, the NFC reader / writer 31 is switched so that the NFC terminal device 60 can access it.

  When the NFC tag 32 is in the first position, in principle, the NFC reader / writer 31 is not supplied with power and cannot communicate. However, when an abnormality such as a failure occurs in the water heater main body 3 or the like, the NFC reader / writer 31 is exceptionally supplied with power, and the NFC reader / writer 31 writes the generated abnormality information in the NFC tag 32. It is configured. When the writing of the abnormality information to the NFC tag 32 is completed, the NFC reader / writer 31 stops supplying power and returns to a state where communication is not possible.

  Next, with reference to FIG.1 and FIG.4, the method to acquire data with the NFC terminal device 60 from the NFC tag 32 of the remote controller 10 for hot water heaters is demonstrated. FIG. 4 is a diagram illustrating a state in which the NFC terminal device 60 communicates with the NFC tag 32 of the hot water supply remote controller 10. The NFC terminal device 60 illustrated in FIG. 1 and the like is, for example, a smartphone and includes an NFC communication unit 61 and a LAN communication unit 62. In addition, a dedicated application that enables communication with the NFC reader / writer 31 and the NFC tag 32 is installed in the NFC terminal device 60.

  The water heater remote control 10 is normally in a state where the lid 14 is closed. Acquisition of data from the NFC tag 32 is performed by holding the NFC terminal device 60 in front of the mark 33 as shown in FIG. When the lid 14 is in the closed state, the NFC tag 32 is in the first position, and therefore the NFC terminal device 60 cannot access the NFC reader / writer 31. Therefore, even if the NFC terminal device 60 is held in front of the mark 33 as shown in FIG. 4, the NFC terminal device 60 does not access the NFC reader / writer 31, and reliably communicates with the NFC tag 32. Data can be acquired from 32.

  The above-described operation of acquiring data from the NFC tag 32 is merely an example, but is performed by the user when a failure occurs in the water heater main body 3, for example. The abnormality information acquired by the user in the NFC terminal device 60 is sent in advance to the repair worker's server 64 via the network 63 (see FIG. 1). The information sent to the repair worker is used for inferring the cause of failure and preparing replacement parts and confirming the repair process.

  Next, with reference to FIG.1 and FIG.5, the method to acquire data with the NFC terminal device 60 from the NFC reader / writer 31 of the remote controller 10 for hot water heaters is demonstrated. FIG. 5 is a diagram illustrating a state in which the NFC terminal device 60 communicates with the NFC reader / writer 31 of the water heater remote control 10.

  In order to acquire data from the NFC reader / writer 31, it is necessary to change the position of the second memory before the NFC terminal device 60 is held over the water heater remote controller 10. First, the lid 14 in the closed state is opened, and the NFC reader / writer 31 is made accessible by the NFC terminal device 60. Thereafter, as shown in FIG. 5, the NFC terminal device 60 is held over a place where the NFC reader / writer 31 is built. Thereby, the NFC terminal device 60 can communicate with the NFC reader / writer 31 and acquire internal information from the NFC reader / writer 31. Moreover, the distance between the NFC reader / writer 31 and the NFC tag 32 is increased by opening the lid 14. Therefore, the NFC terminal device 60 can be brought close to the NFC reader / writer 31 so as not to access the NFC tag 32 and can be securely connected to the NFC reader / writer 31.

  The operation of acquiring data from the NFC reader / writer 31 is merely an example, but is performed for the purpose of bringing the NFC terminal device 60 together with the data to the center for failure cause analysis, for example, by a repair worker.

  In this embodiment, when the lid 14 is in the closed state, the NFC terminal device 60 cannot access the NFC reader / writer 31. For this reason, it is possible to make the NFC terminal device 60 accessible only to the NFC tag 32. As a result, even if the NFC reader / writer 31 and the NFC tag 32 are close to each other, the NFC tag can be surely handled without error with the information of the NFC reader / writer 31 by a simple operation of holding the NFC terminal device 60 over the water heater remote controller 10. 32 pieces of information can be acquired.

  Further, by shifting the lid 14 from the closed state to the open state, the NFC tag 32 is moved from the first position to the second position, and the NFC reader / writer 31 is changed to an accessible state. Can be acquired by the NFC terminal device 60.

  Thus, the NFC terminal device 60 can acquire appropriate data according to the situation by a simple operation.

  Further, since the NFC tag 32 can communicate with the NFC terminal device 60 regardless of whether or not the hot water heater remote controller 10 is energized, the hot water heater remote controller 10 itself is not energized due to, for example, failure of the hot water heater remote controller 10 itself. Even at times, it is possible to acquire the internal data of the remote controller 10 for the water heater.

  In this embodiment, when the NFC tag 32 is in the first position, a positional relationship in which the NFC reader / writer 31 and the NFC tag 32 can communicate with each other can be ensured. Further, when the NFC tag 32 is in the second position, the NFC reader / writer 31 and the NFC tag 32 are separated from each other than when the NFC tag 32 is in the first position, and it is desired to obtain the information of the NFC reader / writer 31 and the NFC tag 32. Data can be appropriately acquired by bringing the NFC terminal device closer to the person who has the information.

  Further, in this embodiment, by providing the NFC tag 32 on the lid 14, the change of the position of the NFC tag 32 with respect to the NFC reader / writer 31 provided on the housing 11 is realized with a simple configuration and a simple operation. be able to.

(Second Embodiment)
Next, with reference to FIGS. 6-9, the water heater remote control 70 which concerns on 2nd Embodiment of this invention is demonstrated. In addition, since the remote controller for hot water heater 70 of the present embodiment is similar to the remote controller for hot water heater 10 of the first embodiment except for a position changing mechanism that changes the position of the NFC tag 32 with respect to the NFC reader / writer 31, The position changing mechanism will be mainly described. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  The remote controller 70 for the hot water heater of the present embodiment is a protruding piece provided as a component whose position can be changed with respect to the casing 11 so as to protrude from the inside of the casing 11 to the outside instead of the lid 14. 71 is provided. FIG. 6 shows a state where the entire protruding piece 71 is accommodated inside the housing 11 (accommodating state), and FIG. 7 shows a state where a part of the protruding piece 71 protrudes outside the housing 11 (projecting state). ). An insertion hole 74 for inserting the protruding piece 71 is formed on the right side surface of the housing 11. As shown by the broken lines in FIGS. 6A and 6B, the protruding piece 71 is normally disposed in a state where the entire protruding piece 71 is accommodated in the insertion hole 74. Further, an eject switch 72 is provided on the right side surface of the casing 11, and the protruding piece 71 is configured such that a part of the protruding piece 71 protrudes from the right side surface of the casing 11 when the eject switch 72 is pressed. It is configured.

  An NFC tag 32 is provided at the protruding portion of the protruding piece 71 in the protruding state. The NFC tag 32 is disposed at the first position when the protruding piece 71 is in the accommodated state, and is disposed at the second position when the protruding piece 71 is in the protruded state. The housing 11 is provided with a position detection unit 73 that detects whether or not the NFC tag 32 is in the first position.

  Further, the NFC reader / writer 31 provided in the housing 11 is disposed so as to be close to the NFC tag 32 when the protruding piece 71 is in the accommodated state (see FIG. 6). In addition, a mark 33 indicating a position where the NFC terminal device 60 is held is attached to the housing main surface portion 11a of the housing 11 so that the position of the NFC tag 32 when the protruding piece 71 is in the accommodated state can be seen.

  FIG. 8 is a diagram illustrating a state in which the NFC terminal device 60 communicates with the NFC tag 32 of the remote controller 70 for hot water heater. Also in this embodiment, when the NFC tag 32 is in the first position, the NFC terminal device 60 cannot access the NFC reader / writer 31. For this reason, even if the NFC terminal device 60 is held in front of the mark 33 as shown in FIG. 8, the NFC terminal device 60 does not access the NFC reader / writer 31, but communicates with the NFC tag 32 reliably. Internal information can be acquired from 32.

  FIG. 9 is a diagram illustrating a state in which the NFC terminal device 60 communicates with the NFC reader / writer 31 of the remote controller for water heater 70. Also in this embodiment, in order to acquire data from the NFC reader / writer 31, first, by pushing the eject switch 72, the position of the NFC tag 32 is moved from the first position to the second position. 31 is made accessible by the NFC terminal device 60. Thereafter, as shown in FIG. 9, the NFC terminal device 60 is held over a place where the NFC reader / writer 31 is built. Thereby, the NFC terminal device 60 can communicate with the NFC reader / writer 31 and acquire internal information from the NFC reader / writer 31. Further, since the distance between the NFC reader / writer 31 and the NFC tag 32 is increased, the NFC terminal device 60 is brought close to the NFC reader / writer 31 so as not to access the NFC tag 32 and is securely connected to the NFC reader / writer 31. It becomes possible.

  Also in this embodiment, the same effect as the first embodiment can be obtained. Also in this embodiment, the change of the position of the NFC tag 32 with respect to the NFC reader / writer 31 provided in the housing 11 can be realized with a simple configuration and a simple operation.
