(Embodiment 1)
Here, the communication apparatus 10 according to the present embodiment will be described with reference to FIGS. The communication device 10 is, for example, a fire detection device. As shown in FIG. 2, the plurality of communication devices 10 and the management device 100 (external device) constitute a wireless communication system 1. The plurality of communication devices 10 and the management device 100 are installed in the same house. When one communication device 10 detects a fire, it transmits a fire detection signal indicating that a fire has been detected to the management device 100 wirelessly. When receiving the fire detection signal, the management device 100 notifies other devices that a fire has occurred via the Internet or the like.

  The communication device 10 receives power supply from a battery 11 to be described later, and performs a first operation mode for performing a normal operation including an operation for communicating with the management device 100, and a second operation for performing a standby operation with lower power consumption than the first operation mode. It operates in one of the operation modes. The communication device 10 operates in the second operation mode at the time of shipment.

  The communication device 10 receives a power supply from the battery 11 and operates in the second operation mode, accepts a transition instruction from the second operation mode to the first operation mode from the user, and satisfies a predetermined transition condition. When doing so, the mode shifts from the second operation mode to the first operation mode.

  Further, the wireless communication system 1 includes a maintenance apparatus 101 as shown in FIG. The maintenance device 101 is a device possessed by, for example, a maintenance person who is requested to repair the communication device 10 and performs wireless communication with the communication device 10.

  When the communication device 10 is operating in the first operation mode and receives a transition message indicating an instruction to shift from the maintenance device 101 to the second operation mode, the communication device 10 shifts from the first operation mode to the second operation mode. .

  Hereinafter, the configuration of the communication device 10 will be described. As shown in FIG. 1, the communication device 10 includes a main body 10 </ b> A, a battery 11, and an operation unit 12. Main unit 10A receives power supply from battery 11 and operates in one of the first operation mode and the second operation mode. As shown in FIG. 1, the main body unit 10 </ b> A includes a fire detection unit 13, a communication unit 14, and a control unit 15.

  The battery 11 is a power source that supplies power for operating the communication device 10, and is, for example, a lithium battery. The battery 11 is installed so that it cannot be removed from the communication device 10. In the present embodiment, in the first operation mode, the operation unit 12 and the main body unit 10 </ b> A are supplied with power from the battery 11. Specifically, the operation unit 12, the fire detection unit 13, the communication unit 14, and the control unit 15 are supplied with power from the battery 11. In the second operation mode, part of the operation unit 12 and the main body unit 10 </ b> A is supplied with power from the battery 11. Specifically, the operation unit 12 and the control unit 15 are supplied with power from the battery 11. In the present embodiment, the operation state of the communication unit 14 when power is supplied to the communication unit 14 is referred to as a communicable state, and the operation state of the communication unit 14 when power is not supplied (communication unit 14). The state where the operation is stopped) is referred to as a communication disabled state. The operation state of the fire detection unit 13 when power is supplied to the fire detection unit 13 is referred to as a fire-detectable state, and the operation state of the fire detection unit 13 when no power is supplied (fire detection) The state in which the operation of the unit 13 is stopped) is called a fire detection impossible state.

  The operation unit 12 includes operation buttons and accepts an operation from the user. The operation unit 12 is a circuit that receives power supply from the battery 11 and includes a circuit (operation circuit) that outputs a signal to the control unit 15 described later when an operation button is pressed. The operation unit 12 receives a power supply from the battery 11 and receives a transition instruction when the user presses the operation button for a long time while the main body unit 10A is operating in the second operation mode. At this time, the operation circuit of the operation unit 12 outputs a signal to the control unit 15 while the operation button is held down. Here, the long press means that the operation button of the operation unit 12 is pressed for, for example, 1 second or longer. However, this value is an example and is not intended to be limited to this value.

  The fire detector 13 is, for example, a heat detector, a smoke detector, a flame detector, or the like, and detects the presence or absence of a fire. The fire detection unit 13 is in a fire-detectable state in the first operation mode, and is in a fire-detection disabled state in the second operation mode. When the operation mode is shifted from the second operation mode to the first operation mode, the fire detection unit 13 is changed from the fire detection disabled state to the fire detection enabled state by the control of the processing unit 23 described later.

  The communication unit 14 is a communication circuit that performs wireless communication, for example, a communication circuit that performs wireless communication at a short distance. The communication unit 14 periodically communicates with the management apparatus 100 while operating in the first operation mode. Thereby, the management apparatus 100 can confirm the presence of the communication apparatus 10. In addition, when the fire detection unit 13 detects a fire, the communication unit 14 transmits a fire detection signal to the management device 100. The communication unit 14 is activated under the control of the processing unit 23 described later when the operation unit 12 receives a transition instruction while the main body unit 10A is operating in the second operation mode, and the operation state cannot be communicated. The status is changed to the communication enabled status. And the communication part 14 transmits the communication start signal showing starting communication to the management apparatus 100 by control of the process part 23. FIG. After the communication start signal is transmitted, the communication unit 14 enters a reception wait state for a response signal indicating that the communication start signal has been received.

  The control unit 15 has, for example, a microcomputer (microcontroller) as a main configuration, and realizes a desired function by executing a program stored in a memory. Note that the program may be written in a memory in advance or may be provided by being stored in a recording medium such as a memory card.

  As illustrated in FIG. 1, the control unit 15 includes a first determination unit 21, a second determination unit 22, and a processing unit 23.

  The first determination unit 21 receives power supply from the battery 11 and is in a state where the main unit 10A is operating in the second operation mode, whether or not a transition instruction is received by the operation unit 12 (operation button of the operation unit 12). Whether or not is pressed for a long time. Specifically, the first determination unit 21 operates when the main unit 10A operates in the second operation mode and receives a signal output from the operation circuit of the operation unit 12 for 1 second or longer. The unit 12 determines that the transfer instruction has been accepted.

  When the first determination unit 21 determines that the operation unit 12 has received a transition instruction, the second determination unit 22 determines that there is a transition condition for shifting from the second operation mode to the first operation mode within a predetermined time. It is determined whether or not it is established. Specifically, the second determination unit 22 determines whether the communication unit 14 has received a response signal from the management device 100 within a predetermined time after the communication unit 14 has transmitted a communication start signal to the management device 100. To do. The second determination unit 22 determines that the transition condition is satisfied when the response signal is received within a predetermined time after the communication start signal is transmitted. The second determination unit 22 determines that the transition condition is not satisfied when the response signal is not received within a predetermined time after the communication start signal is transmitted. Here, the predetermined time is, for example, 30 seconds. However, this value is an example and is not intended to be limited to this value.

  The processing unit 23 controls the operation of the main unit 10A in one of the first operation mode and the second operation mode. Specifically, the processing unit 23 controls the operation of the main unit 10A in the second operation mode until a transition instruction is accepted by the operation unit 12 and a predetermined transition condition is satisfied.

  When the first determination unit 21 determines that the operation unit 12 has received the transition instruction, the processing unit 23 changes the operation state of the communication unit 14 from the communication disabled state to the communication enabled state. Specifically, the processing unit 23 starts power supply from the battery 11 to the communication unit 14 and activates the communication unit 14. The processing unit 23 controls the communication unit 14 so that the communication unit 14 transmits a communication start signal to the management apparatus 100. With this control, the communication unit 14 transmits a communication start signal to the management apparatus 100.

  When the second determination unit 22 determines that the predetermined transition condition is satisfied, the processing unit 23 shifts the operation mode of the main body unit 10A from the second operation mode to the first operation mode, and thereafter the first operation mode. Control the operation with. At this time, the processing unit 23 activates the fire detection unit 13. Specifically, the processing unit 23 starts supplying power from the battery 11 to the fire detection unit 13. As a result, the operation unit 12, the fire detection unit 13, the communication unit 14, and the control unit 15 are supplied with power from the battery 11. As a result, the operation state of the fire detection unit 13 is changed from the fire detection disabled state to the fire detection enabled state.

  When the second determination unit 22 determines that the predetermined transition condition is not satisfied, the processing unit 23 sets the operation state of the communication unit 14 to the communication disabled state. Specifically, the processing unit 23 stops the operation of the communication unit 14 by stopping the power supply from the battery 11 to the communication unit 14, and subsequently causes the main body unit 10A to operate in the second operation mode.

  Further, when the main unit 10A is operating in the first operation mode and the communication unit 14 receives the transition message from the maintenance device 101, the processing unit 23 changes the operation mode of the main unit 10A from the first operation mode. Transition to the second operation mode. In this case, the processing unit 23 stops the power supply from the battery 11 to the fire detection unit 13 and the communication unit 14 in the main body unit 10A. Thereby, the operation state of the communication unit 14 is changed from the communicable state to the communicable state.

  When the fire detection unit 13 detects a fire, the processing unit 23 controls the communication unit 14 to transmit a fire detection signal to the management apparatus 100.

  For example, the communication device 10 operates in the second operation mode at the time of shipment, and when the purchaser (user) of the communication device 10 wants the communication device 10 to start fire detection, the operation mode is changed from the second operation mode. Transition to the first operation mode.

  Next, the operation of the communication apparatus 10 relating to the transition from the second operation mode to the first operation mode will be described using the flowchart shown in FIG.

  The first determination unit 21 determines whether or not the operation unit 12 has received a transition instruction in a state where the main body unit 10A is operating in the second operation mode upon receiving power supply from the battery 11 (step S1). Specifically, the first determination unit 21 determines whether or not the operation button of the operation unit 12 has been pressed for a long time.

  If the first determination unit 21 determines that the operation unit 12 has not received a shift instruction (“No” in step S1), the process waits for a shift instruction.

  When the first determination unit 21 determines that the operation unit 12 has accepted the transition instruction (“Yes” in step S1), the second determination unit 22 determines whether the communication has been successful within a predetermined time ( Step S2). Specifically, the second determination unit 22 determines whether or not the communication unit 14 has received a response signal within a predetermined time after the communication unit 14 transmits a communication start signal to the management apparatus 100. At this time, the processing unit 23 changes the operation state of the communication unit 14 from the communication disabled state to the communication enabled state, and controls the communication unit 14 to transmit a communication start signal to the management apparatus 100.

  When the second determination unit 22 determines that the communication is successful (“Yes” in step S2), the processing unit 23 shifts the operation mode from the second operation mode to the first operation mode (step S3). Specifically, the second determination unit 22 determines that the communication is successful (the transition condition is satisfied) when the communication unit 14 receives the response signal within a predetermined time after transmitting the communication start signal. .

  When the second determination unit 22 determines that the communication is unsuccessful (“No” in step S2), the processing unit 23 maintains the second operation mode (step S4). Specifically, the second determination unit 22 is unsuccessful in communication when the communication unit 14 does not receive a response signal within a predetermined time after the communication start signal is transmitted (the transition condition is not satisfied). ). In this case, the processing unit 23 changes the operation state of the communication unit 14 from the communicable state to the communicable state. Specifically, the processing unit 23 stops the power supply from the battery 11 to the communication unit 14 and stops the operation of the communication device 10. Also, the process waits for acceptance of a migration instruction.

  Next, the operation of the communication apparatus 10 relating to the transition from the first operation mode to the second operation mode will be described using the flowchart shown in FIG.

  When the main unit 10A is operating in the first operation mode, the processing unit 23 determines whether the communication unit 14 has received a migration message from the maintenance device 101 (step S10). When it is determined that the communication unit 14 has received the transition message (“Yes” in step S10), the processing unit 23 transitions the operation mode from the first operation mode to the second operation mode (step S11). If it is determined that the communication message 14 is not received by the communication unit 14 (“No” in step S10), the processing unit 23 continues to operate the main unit 10A in the first operation mode and waits for reception of the transfer message.

  In the present embodiment, the communication device 10 is a fire detection device, but is not limited thereto. The communication device 10 may be a device that detects an intruder when the house is absent, or may be a device that reports an abnormality in the house to a device outside the house via the management device 100. That is, the communication device 10 may be a security device that is driven by the battery 11 and performs wireless communication with the management device 100.

  In the present embodiment, the battery 11 may be included in the components of the communication device 10 or may not be included in the components of the communication device 10. Further, the battery 11 may be configured to be removable, or may be configured to be externally attached to the communication device 10.

  In the present embodiment, the communication apparatus 10 has received the transition instruction by long pressing the operation button of the operation unit 12, but is not limited thereto. The communication device 10 may accept the transition instruction by continuously pressing the operation button of the operation unit 12 a predetermined number of times. Further, when the operation unit 12 includes a plurality of operation buttons, the transition instruction may be received by pressing at least two operation buttons simultaneously.

  In the present embodiment, the communication device 10 shifts the operation mode from the first operation mode to the second operation mode when receiving the shift message from the maintenance device 101 while operating in the first operation mode. However, the present invention is not limited to this. When the communication device 10 is operating in the first operation mode and receives a transition message from the maintenance device 101 while receiving a predetermined operation, the communication device 10 changes the operation mode from the first operation mode to the second operation mode. You may enter mode. Here, the predetermined operation is, for example, that an operation button of the operation unit 12 is pressed. Further, when the operation unit 12 includes a plurality of operation buttons, the predetermined operation may be that at least two operation buttons are pressed simultaneously.

  In the present embodiment, the communication apparatus 10 receives the migration message from the maintenance apparatus 101. However, the present invention is not limited to this. The communication device 10 may receive the migration message from the management device 100.

  As described above, the communication device 10 according to the present embodiment includes the communication unit 14, the main body unit 10 </ b> A that operates by receiving power supply from the battery 11, the operation unit 12, the processing unit 23, and the first determination unit. 21 and a second determination unit 22. The processing unit 23 controls the operation of the main unit 10A in any one of the first operation mode in which the normal operation is performed and the second operation mode in which the standby operation with lower power consumption than the first operation mode is performed. The first determination unit 21 determines whether or not the operation unit 12 has received an instruction to shift to the first operation mode when the operation mode is the second operation mode. The second determination unit 22 determines whether or not a transition condition for shifting the operation mode from the second operation mode to the first operation mode is satisfied when the first determination unit 21 determines that the transition instruction has been received. to decide. When the second determination unit 22 determines that the transition condition is satisfied, the processing unit 23 shifts the operation mode from the second operation mode to the first operation mode.

  According to this configuration, since the communication device 10 operates in the second operation mode until the transition instruction is accepted and the transition condition is satisfied, the battery life is longer than that in the case of operating in the first operation mode. Can be achieved. In addition, the communication device 10 shifts the operation mode from the second operation mode to the first operation mode through the determination by the first determination unit 21 and the determination by the second determination unit 22, in other words, through two-stage determination. . Therefore, for example, it is possible to prevent the operation mode from being shifted due to an erroneous operation such that the user erroneously operates the operation unit 12 and inputs a shift instruction. In addition, it is not an essential requirement that the battery 11 cannot be removed. Even when the battery 11 can be removed, the communication device 10 can extend the life of the battery 11 by providing the above-described configuration requirements, and further prevent the operation mode from being shifted due to an erroneous operation. be able to. However, when the battery 11 cannot be removed, the power of the battery 11 is consumed from the time of shipment. Thus, providing the above-described components provides a more effective effect than when the battery 11 can be removed. Remarkably can be obtained.

  Here, when the first determination unit determines that the operation unit 12 has accepted the transition instruction, the processing unit 23 sets the operation state of the communication unit to the communicable state, and the communication unit 14 sends a signal ( The communication unit 14 is controlled to transmit a communication start signal. The second determination unit 22 determines that the transition condition is satisfied when the communication unit 14 receives a response signal to the communication start signal from the management device 100 within a predetermined time after the communication start signal is transmitted. The second determination unit 22 determines that the transition condition is not satisfied when the communication unit 14 does not receive a response signal from the external device within a predetermined time. The processing unit 23 preferably stops the operation of the communication unit 14 when the second determination unit 22 determines that the transition condition is not satisfied.

  Even if a transition instruction is accepted in a situation where communication with the management apparatus 100 is not possible and the operation mode is shifted from the second operation mode to the first operation mode, communication with the management apparatus 100 is not performed. Battery consumption is wasted consumption. Therefore, according to this configuration, the communication device 10 determines that the transition condition is satisfied when the response signal is received within a predetermined time after the communication start signal is transmitted. Therefore, even if a transition instruction is accepted in a situation where communication with the management apparatus 100 is not possible, the operation mode does not shift from the second operation mode to the first operation mode. Thereby, the communication apparatus 10 can prevent the transition from the second operation mode to the first operation mode due to an erroneous operation, and can extend the life of the battery.

  Here, 10 A of main-body parts contain the fire detection part 13 which detects a fire. When the second determination unit 22 determines that the transition condition is satisfied, the processing unit 23 preferably sets the operation state of the fire detection unit 13 to a fire detectable state.

  According to this configuration, since the communication device 10 makes the operation state of the fire detection unit 13 detectable after two stages of determination, the possibility of making the operation state of the fire detection unit 13 detectable by an erroneous operation is low. can do.

  Here, when the operation mode is the first operation mode, the communication unit 14 receives a transition message indicating an instruction to shift to the second operation mode. In this case, it is preferable that the processing unit 23 shifts the operation mode from the first operation mode to the second operation mode.

  According to this configuration, the communication device 10 can shift the operation mode from the first operation mode to the second operation mode. Thus, for example, when the communication device 10 is not temporarily used due to moving or the like, the battery consumption during that time can be suppressed, so that the life of the battery can be extended.

  Here, it is preferable that the processing unit 23 shifts the operation mode from the first operation mode to the second operation mode when the communication unit 14 receives the transition message while the operation unit 12 accepts a specific operation. .

  According to this configuration, the communication device 10 does not shift the operation mode from the first operation mode to the second operation mode even if a message is received from a specific device unless a specific operation is being received. As a result, even if the transition message is transmitted by mistake, the operation mode is not shifted from the first operation mode to the second operation mode. Therefore, the communication device 10 can prevent the operation mode from being shifted due to an erroneous operation.

In the second operation mode, part of the operation unit 12 and the main body unit 10 </ b> A is supplied with power from the battery 11. Specifically, the operation unit 12 and the control unit 15 are supplied with power from the battery 11. In this embodiment, the operation state of the installation detection unit 16 when power is supplied to the installation detection unit 16 is referred to as an installation detection possible state, and the operation state of the installation detection unit 16 when power is not supplied. (A state where the operation of the installation detection unit 16 is stopped) is referred to as an installation detection impossible state.

  The installation detection unit 16 is, for example, a magnetic detection circuit, and detects whether or not the housing of the communication device 10 that houses at least the main body unit 10A and the processing unit 23 is installed on a wall of a house. The installation detection unit 16 detects whether or not the casing of the communication device 10 is installed depending on whether or not the magnetism of a mounting base (base) provided with a magnet provided at an installation location such as a wall is detected. . The installation detection unit 16 is activated by the control of the processing unit 23 when the operation unit 12 receives a transition instruction while operating in the second operation mode, and the operation state changes from the installation detection disabled state to the installation detection enabled state. Is changed to

  When the first determination unit 21 determines that the transition instruction has been received, the second determination unit 22 of the present embodiment satisfies a transition condition for shifting from the second operation mode to the first operation mode within a predetermined time. Judge whether to do. Specifically, the second determination unit 22 determines whether the installation of the casing of the communication device 10 has been detected within a predetermined time after the installation detection unit 16 becomes in a state where installation detection is possible by the control of the processing unit 23. to decide. The second determination unit 22 determines that the transition condition is satisfied when the installation detection unit 16 detects the installation of the housing of the communication device 10 within a predetermined time after the detection becomes possible. The second determination unit 22 determines that the transition condition is not satisfied when the installation detection unit 16 does not detect that the casing of the communication device 10 has been installed within a predetermined time after the installation detection unit 16 becomes in a detectable state. To do. Here, the predetermined time is, for example, 60 seconds. However, this value is an example and is not intended to be limited to this value.

  When the first determination unit 21 determines that the transfer instruction has been received by the operation unit 12, the processing unit 23 changes the operation state of the installation detection unit 16 from the installation detection disabled state to the installation detection enabled state. Specifically, the processing unit 23 starts power supply from the battery 11 to the installation detection unit 16 and activates the installation detection unit 16.

  When the second determination unit 22 determines that the predetermined transition condition is satisfied, the processing unit 23 shifts the operation mode of the main body unit 10A from the second operation mode to the first operation mode, and thereafter in the first operation mode. Control the behavior. Specifically, the processing unit 23 starts the fire detection unit 13 and the communication unit 14 by starting power supply from the battery 11 to the fire detection unit 13 and the communication unit 14. The operation unit 12, the fire detection unit 13, the communication unit 14, the control unit 15, and the installation detection unit 16 are supplied with power from the battery 11. As a result, the operation state of the fire detection unit 13 is changed from the fire detection disabled state to the fire detection enabled state.

  When the second determination unit 22 determines that the predetermined transition condition is not satisfied, the processing unit 23 stops the operation of the installation detection unit 16 by stopping the power supply from the battery 11 to the installation detection unit 16. Subsequently, the main body 10A is operated in the second operation mode.

  Next, the operation of the communication apparatus 10 according to the present embodiment relating to the transition from the second operation mode to the first operation mode will be described with reference to the flowchart shown in FIG.

  The first determination unit 21 determines whether the operation unit 12 has received a transition instruction in a state where the main body unit 10A is operating in the second operation mode upon receiving power supply from the battery 11 (step S20). Specifically, the first determination unit 21 determines whether or not the operation button of the operation unit 12 has been pressed for a long time.

  When the first determination unit 21 determines that the operation unit 12 has not received the transition instruction (“No” in step S20), the main body unit 10A is continuously operated in the second operation mode, and the process waits for the transition instruction to be received. It becomes.

  When the first determination unit 21 determines that the operation unit 12 has received the transition instruction (“Yes” in step S20), the second determination unit 22 detects the installation of the casing of the communication device 10 within a predetermined time. Whether or not (step S21). Specifically, the second determination unit 22 determines whether the magnetism of the magnet included in the base is detected within a predetermined time after the detection function of the installation detection unit 16 is activated. At this time, the processing unit 23 changes the operation state of the installation detection unit 16 from the installation detection disabled state to the installation detection enabled state.

  When the second determination unit 22 determines that the housing of the communication device 10 has been installed (“Yes” in step S21), the processing unit 23 changes the operation mode from the second operation mode to the first operation. The mode is changed (step S22). Specifically, the second determination unit 22 installs the casing of the communication device 10 when the installation detection unit 16 detects the magnetism of the magnet included in the base within a predetermined time after the installation detection unit 16 becomes ready for installation detection. It is determined that the transition condition is satisfied.

  When the second determination unit 22 determines that it is not detected that the housing of the communication device 10 has been installed (“No” in step S21), the processing unit 23 maintains the second operation mode (step S23). . Specifically, the second determination unit 22 installs the casing of the communication device 10 when the installation detection unit 16 does not detect the magnetism of the magnet included in the base within a predetermined time after the installation detection unit 16 becomes ready for installation detection. That it is not detected (the transition condition is not satisfied). In this case, the processing unit 23 changes the operation state of the installation detection unit 16 from the installation detection enabled state to the installation detection disabled state. Specifically, the processing unit 23 stops power supply from the battery 11 to the installation detection unit 16. Also, the process waits for acceptance of a migration instruction.

  As described above, in the communication device 10 of the present embodiment, the main body unit 10A includes the installation detection unit 16 that detects whether or not a housing that houses at least the main body unit 10A and the processing unit 23 is installed. When the first determination unit 21 determines that the operation unit 12 has received a transition instruction, the processing unit 23 sets the operation state of the installation detection unit 16 to a state where detection is possible. The second determination unit 22 determines that the transition condition is satisfied when the installation detection unit 16 detects the installation of the casing within a predetermined time after the installation detection unit 16 becomes in the installation-detectable state. The second determination unit 22 determines that the transition condition is not satisfied when the installation detection unit 16 does not detect the installation of the housing within a predetermined time. The processing unit 23 preferably stops the operation of the installation detection unit 16 when the second determination unit 22 determines that the transition condition is not satisfied.

  The communication device 10 is used in a state of being fixed (installed) on a wall or the like in a house. Therefore, according to this configuration, the communication apparatus 10 determines that the transition condition is satisfied when the installation detection unit 16 detects the completion of the installation within a predetermined time after the installation detection enabled state. Therefore, even if a transition instruction is accepted in a state where there is no intention to use the communication device 10 (a state where there is no intention to install the communication device 10), the operation mode is not shifted from the second operation mode to the first operation mode. Absent. Thereby, the communication apparatus 10 can prevent the operation mode from being shifted due to an erroneous operation, and can extend the life of the battery.

(Embodiment 3)
In the second embodiment, the second determination unit 22 determines whether the transition condition is satisfied based on the detection result of the installation detection unit 16. In the present embodiment, the second determination unit 22 determines whether the transition condition is in accordance with the result of whether the communication described in the first embodiment is successful and the detection result of the installation detection unit 16 described in the second embodiment. It is determined whether or not it is established. In the following description, differences from the second embodiment will be mainly described. In addition, the same components as those in the second embodiment are denoted by the same reference numerals, and description thereof is omitted as appropriate. In the following description, as in the first embodiment, the operation state of the communication unit 14 when power is supplied to the communication unit 14 is referred to as a communicable state, and communication is performed when power is not supplied. The operation state of the unit 14 is referred to as a communication disabled state.

  When the first determination unit 21 determines that the transition instruction has been received, the processing unit 23 of the present embodiment changes the operation state of the communication unit 14 from the communication disabled state to the communication enabled state, and changes the operation state of the installation detection unit 16. Change from the undetectable state to the detectable state. Specifically, the processing unit 23 starts power supply from the battery 11 to the communication unit 14 and the installation detection unit 16 and activates the communication unit 14 and the installation detection unit 16.

  The second determination unit 22 determines whether or not the communication with the management apparatus 100 is successful within a predetermined time (first predetermined time), and the communication apparatus 10 is installed within the predetermined time (second predetermined time). It is determined whether or not it has been done. Here, the first predetermined time is, for example, 30 seconds, and the second predetermined time is, for example, 60 seconds. However, these values are merely examples, and are not intended to limit these values.

  If the communication is successful within the first predetermined time and the installation of the communication device 10 is detected within the second predetermined time, the processing unit 23 shifts from the second operation mode to the first operation mode. Thereafter, the operation is controlled in the first operation mode. Specifically, the processing unit 23 starts the fire detection unit 13 by starting power supply from the battery 11 to the fire detection unit 13. In the fire detection unit 13, the operation unit 12, the communication unit 14, the control unit 15, and the installation detection unit 16, power from the battery 11 is supplied. As a result, the operation state of the fire detection unit 13 is changed from the fire detection disabled state to the fire detection enabled state.

  If the communication is not successful within the first predetermined time, or if the installation of the communication device 10 is not detected within the second predetermined time, the processing unit 23 stops the operations of the communication unit 14 and the installation detection unit 16. Then, the main body 10A is continuously operated in the second operation mode. Specifically, the processing unit 23 stops the operation of the communication unit 14 and the installation detection unit 16 by stopping the power supply from the battery 11 to the communication unit 14 and the installation detection unit 16.

  The operation of the communication device 10 in this case will be described with reference to FIG.

  The first determination unit 21 determines whether or not the operation unit 12 has received a transition instruction in a state in which power is supplied from the battery 11 and is operating in the second operation mode (step S30). Specifically, the first determination unit 21 determines whether or not the operation button of the operation unit 12 has been pressed for a long time.

  When it is determined by the first determination unit 21 that the operation unit 12 has not received the shift instruction (“No” in step S30), the processing unit 23 continues to operate the main body unit 10A in the second operation mode, and the process is shifted. Waiting to receive instructions.

  When the first determination unit 21 determines that the operation unit 12 has accepted the transition instruction (“Yes” in step S30), the second determination unit 22 determines whether the communication has been successful within the first predetermined time. Judgment is made (step S31). Specifically, the second determination unit 22 determines whether the communication unit 14 has received a response signal within a first predetermined time after the communication unit 14 transmits a communication start signal to the management apparatus 100. . At this time, the processing unit 23 changes the operation state of the communication unit 14 from the communication disabled state to the communication enabled state, and controls the communication unit 14 to transmit a communication start signal to the management apparatus 100.

  When it is determined that the communication is successful (“Yes” in step S31), the second determination unit 22 determines whether the installation detection unit 16 has detected the installation of the casing of the communication device 10 within the second predetermined time. Is determined (step S32). Specifically, the second determination unit 22 determines whether or not the magnetism of the magnet included in the base has been detected within the second predetermined time after the installation detection unit 16 becomes in a state where installation detection is possible. When the second determination unit determines that the communication is successful, the processing unit 23 changes the operation state of the installation detection unit 16 from the undetectable state to the detectable state.

  When the second determination unit 22 determines that the installation detection unit 16 has detected the installation of the housing of the communication device 10 (“Yes” in step S32), the processing unit 23 changes the operation mode from the second operation mode to the second operation mode. The operation mode is shifted to one operation mode (step S33).

  When the second determination unit 22 determines that the communication is not successful (“No” in step S31), the processing unit 23 maintains the second operation mode (step S34). In addition, when the second determination unit 22 determines that installation of the communication device 10 is not detected (“No” in step S32), the processing unit 23 maintains the second operation mode (step S34). In this case, the processing unit 23 changes the operating state of the communication unit 14 from the communicable state to the incommunicable state, and changes the operating state of the installation detection unit 16 from the detectable state to the undetectable state. Specifically, the processing unit 23 stops power supply from the battery 11 to the communication unit 14 and the installation detection unit 16. Also, the process waits for acceptance of a migration instruction.

  In the operation of the communication device 10 illustrated in FIG. 7, the second determination unit 22 determines the installation completion after determining whether or not the communication is successful. However, the present invention is not limited to this. The order of determination may be reversed.

  Further, in the present embodiment, when the communication is successful, the installation detection unit 16 is set in the installation detectable state. However, the present invention is not limited to this. The timing at which the installation detection unit 16 is set in the installation-detectable state is after the first determination unit 21 determines that the transfer instruction has been received, and before the second determination unit 22 makes a determination, the timing does not matter.

  As described above, in the communication device 10 of the present embodiment, the main body unit 10A includes the installation detection unit 16 that detects whether or not a housing that houses at least the main body unit 10A and the processing unit 23 is installed. When the first determination unit 21 determines that the operation unit 12 has received the transition instruction, the processing unit 23 sets the operation state of the communication unit 14 to the communicable state, and the communication unit 14 transfers to the management device 100 (external device). The communication unit 14 is controlled to transmit a signal (communication start signal). Further, the processing unit 23 sets the operation state of the installation detection unit 16 to a state where installation detection is possible. In the second determination unit 22, the communication unit 14 receives a response signal for the signal from the management device 100 within a first predetermined time after the signal is transmitted, and the installation detection unit 16 is in a state in which installation detection is possible. When the installation detection unit 16 detects the installation of the housing within the second predetermined time, it is determined that the transition condition is satisfied. In the second determination unit 22, the communication unit 14 does not receive a response signal from the management apparatus 100 within the first predetermined time, or the installation detection unit 16 does not detect the installation of the housing within the second predetermined time. In this case, it is determined that the transition condition is not satisfied. When the second determination unit 22 determines that the transition condition is not satisfied, the processing unit 23 preferably stops the operation of the communication unit 14 and the operation of the installation detection unit 16.

  The communication device 10 is used in a state of being fixed (installed) on a wall or the like in a house. Further, even if a transition instruction is accepted in a situation where communication with the management apparatus 100 is not possible and the operation mode is shifted from the second operation mode to the first operation mode, communication with the management apparatus 100 can be performed. As a result, battery consumption is wasted. Therefore, according to this configuration, the communication device 10 receives the response signal within the first predetermined time after the communication start signal is transmitted, and after the installation detection unit 16 becomes in a detectable state, the communication device 10 performs the second predetermined time. When the completion of installation is detected, it is determined that the transition condition is satisfied. Therefore, even if a transition instruction is accepted in a situation where communication with the management apparatus 100 is not possible, the operation mode does not shift from the second operation mode to the first operation mode. Furthermore, even if a transition instruction is received in a state where there is no intention to use the communication device 10 (a state where there is no intention to install the communication device 10), the operation mode is not shifted from the second operation mode to the first operation mode. Absent. Therefore, the communication device 10 can prevent the operation mode from being shifted due to an erroneous operation, and can extend the battery life.
