[0010] The present invention will be described below in accordance with preferred embodiments. It should be noted that the present invention is not limited to the embodiments shown below, and can be modified as appropriate without departing from the spirit of the invention. For example, in the embodiments shown below, a gas alarm is described as an example of an alarm, but it is not limited to a gas alarm; it may also be a fire alarm or a gas and fire integrated alarm capable of detecting and alarming both gas and fire. Furthermore, it may also be a security alarm that detects intruders, etc. Also, in the embodiments shown below, some components are not illustrated or described, but it goes without saying that the details of the omitted technologies are appropriately based on publicly known or well-known technologies, to the extent that they do not contradict the content described below.

[0011] FIG. 1 is a perspective view showing the usage state of the gas alarm according to an embodiment of the present invention, and FIG. 2 is a perspective view showing how the gas alarm according to an embodiment of the present invention is attached. Further, FIG. 3 is a front view showing the gas alarm according to an embodiment of the present invention, and FIG. 4 is a side view showing the gas alarm according to an embodiment of the present invention.

[0012] As shown in FIG. 1, the gas alarm 1 according to the present embodiment is a ceiling-mounted alarm that is attached to a rotary mounting portion A provided on the ceiling. As shown in FIG. 2, this gas alarm 1 has a structure that can be attached to the rotary mounting portion A while being rotated, similar to an existing lighting device.

[0013] As shown in FIG. 4, the gas alarm 1 has a contact C on the back surface on the ceiling side. The contact C is a metal member protruding to the back side. Also, as shown in FIG. 2, the rotary mounting portion A also has an electrical contact B. The electrical contact B is located at the bottom of the first groove G1 provided in the rotary mounting portion A. When the gas alarm 1 is attached to the rotary mounting portion A, the contact C on the gas alarm 1 side contacts the electrical contact B of the rotary mounting portion A. As a result, the power supply of the gas alarm 1 is turned on.

[0014] Furthermore, as shown in FIG. 4, in addition to the contact C, the gas alarm 1 is provided with a signal terminal (voltage-bearing contact) D on the back side. This signal terminal D is configured to fit into the second groove G2 shown in FIG. 2 in the state of being attached to the rotary mounting portion A, and functions to transmit a so-called voltage-bearing signal. The voltage-bearing signal becomes a 0V signal, for example, when the gas alarm 1 is removed from the rotary mounting portion A or when a disconnection occurs, a 6V signal in the normal monitoring state of the gas alarm 1, and a 12V signal in the alarm state of the gas alarm 1. The voltage-bearing signal is transmitted to, for example, an alarm monitoring panel such as a management room of an apartment.

[0015] Such a gas alarm 1 includes at least a housing 2 that houses a speaker 34, a gas sensor 24 (see FIG. 6 described later), etc. The housing 2 has a thin and substantially cylindrical shape in appearance, and as shown in FIGS. 3 and 4, it has a housing main body 2a, a lid body 2b, and a panel 2c. The housing main body 2a is a member that constitutes the back side of the housing 2 and is a bottomed cylindrical member with an open front side. The lid body 2b covers the housing main body 2a from the front side (the lower side in the state of being attached to the rotary attachment portion A) which is the open side. The panel 2c is a plate material that fits into a recess D1 (see FIG. 5 described later) formed on the front side of the lid body 2b. The panel 2c is substantially circular in accordance with the shape of the housing 2.

[0016] Also, as shown in FIG. 4, the gas alarm 1 includes a push-down operation portion 10 on the side surface of the housing 2. The gas alarm 1 according to the present embodiment has a function of communicating with an external server OS (see FIG. 7 described later). The push-down operation portion 10 is an operation portion for performing communication settings so as to be communicatively connected to the external server OS. Further, the gas alarm 1 according to the present embodiment can perform an operation of confirming the detection state of a human presence sensor 26 (see FIG. 6 described later). The push-down operation portion 10 is also an operation portion for causing an operation for confirming the human presence sensor 26 to be performed.

[0017] Furthermore, as shown in FIG. 3, the gas alarm 1 includes a stop operation portion 12 on the front side. The stop operation portion 12 is an operation portion for stopping the alarm operation when the gas alarm 1 is performing an alarm operation (sound output and light emission). This stop operation portion 12 is formed by a part (lower right portion) of the panel 2c, and the recess D2 (see FIG. 5 described later) is provided in the lid body 2b so that it can be elastically deformed in the back direction. A warning stop switch 32 (see FIG. 6 described later) is provided on the back side of the stop operation portion 12.

[0018] As described above, the gas alarm 1 according to this embodiment has a separate push operation unit 10 and a stop operation unit 12. If the push operation unit 10 and the stop operation unit 12 were formed in a single operation unit, it would be necessary to differentiate the operations for communication settings and confirmation of the human presence sensor 26 from the operation for stopping the alarm, which would tend to complicate each operation. However, by providing them separately, the complexity of the operations can be suppressed.

[0019] The gas alarm 1 also includes a first lens 14 and a second lens 16. The first lens 14 is a light-transmitting member that is circular when viewed from the front and is located on the upper front side of the gas alarm 1. A human presence sensor 26 (see Figure 6 below) is provided on the back side of the first lens 14. The second lens 16 is a light-transmitting member that is arc-shaped when viewed from the front and is located on the upper front side of the gas alarm 1. A light-emitting part 36 (see Figure 6 below) is provided on the back side of the second lens 16.

[0020] Furthermore, the gas alarm 1 has a speaker hole 18 and a gas hole 20 formed on its front side. The speaker hole 18 is an arc-shaped hole formed approximately to the right of the stop operation unit 12 when viewed from the front. A speaker 34 (see Figure 6 below) is provided on the back side of the speaker hole 18. The gas hole 20 is an arc-shaped hole formed on the lower left side of the gas alarm 1 when viewed from the front. A gas sensor 24 (see Figure 6 below) is provided on the back side of the gas hole 20. These speaker hole 18 and gas hole 20 allow sound from the speaker 34 and the target gas to pass through smoothly.

[0021] Figure 5 is a front view showing the gas alarm 1 shown in Figures 1 to 4 with panel 2c removed, and Figure 6 is a front view showing the gas alarm 1 shown in Figures 1 to 4 with cover 2b and panel 2c removed. Figure 7 is a block diagram showing the software configuration of the gas alarm 1 shown in Figures 1 to 4. For convenience, other components besides the gas alarm 1 are also shown in Figure 7.

[0022] As shown in Figure 6, the gas alarm 1 includes a control board 22 that extends horizontally when mounted on the rotating mounting part A, located within the housing body 2a. Furthermore, as shown in Figures 5 to 7, the gas alarm 1 includes a gas sensor (sensor) 24, a human presence sensor 26, a communication module (communication unit) 28, a communication switch 30, an alarm stop switch 32, a speaker (sound output unit) 34, a light-emitting unit 36, a main microcontroller 38, an audio IC (Integrated Circuit) 40, and an external output unit 42.

[0023] The control board 22 shown in Figure 6 houses the main components of the gas alarm 1. The gas sensor 24 is used to detect abnormalities in the monitoring area. In this embodiment, the gas sensor 24 is a semiconductor gas sensor that reacts to target gases such as city gas and carbon monoxide, and outputs a signal corresponding to the concentration of the target gas to the main microcontroller 38 (see Figure 7). This gas sensor 24 is provided in correspondence with the notch 22a formed in the control board 22. The gas introduction portion 24a of the gas sensor 24 is installed so as to face the gas storage chamber GR formed in correspondence with the gas hole 20.

[0024] The human presence sensor 26 is used to detect the presence of people in the surrounding area and outputs a signal to the main microcontroller 38 (see Figure 7) corresponding to infrared radiation from a living organism, for example. The human presence sensor 26 is not limited to using infrared radiation; it may also be used, for example, to detect moving objects using ultrasound and determine that the moving object is a living organism.

[0025] The communication module 28 shown in Figures 6 and 7 communicates with an external server OS owned by a gas company or the like via a communication line. This communication module 28 communicates with the external server OS by wirelessly connecting to the in-house router R, for example, using the wireless communication standard Wi-Fi (registered trademark), enabling the sending and receiving of information with the external server OS.

[0026] The communication switch 30 shown in Figures 6 and 7 is an operation switch that starts a setting mode for executing communication settings by the main microcontroller 38, and turns on when the push operation unit 10 is pressed. In setting mode, the communication module 28 is wirelessly connected to the in-house router R and communicates with the external server OS. The communication switch 30 is also an operation switch that starts a confirmation mode for checking the detection status by the motion sensor 26. When the confirmation mode is executed, the main microcontroller 38 puts the motion sensor 26 into a standby state and then starts checking the detection status by the motion sensor 26.

[0027] More specifically, when a predetermined operation is performed, the gas alarm 1 first starts a confirmation mode, and after the confirmation mode ends, it starts a setting mode. Here, the predetermined operation is, for example, when the gas alarm 1 is in a normal monitoring state and the push operation unit 10 (communication switch 30) is pressed and held for a predetermined time (e.g., 3 seconds). Alternatively, the predetermined operation may be when the power is turned on while the push operation unit 10 (communication switch 30) is pressed and the pressed state continues for a predetermined time (e.g., 3 seconds). In particular, in this embodiment, since the push operation unit 10 is provided on the side of the housing 2, the gas alarm 1 is configured to be easier to attach to the rotating mounting unit A while pressing the push operation unit 10, as shown in Figure 2, compared to the case where the push operation unit 10 is provided on the front side of the housing 2.

[0028] The alarm stop switch 32 shown in Figures 6 and 7 is located on the back of the stop operation unit 12 (see Figure 3) and is turned on via a first lever member L1 (see Figure 5) provided in the recess D2 (see Figure 5) of the cover 2b when the stop operation unit 12 is pushed toward the back. When the alarm stop switch 32 is turned on, it sends a signal to the main microcontroller 38 to that effect. When the main microcontroller 38 receives a signal indicating that the alarm stop switch 32 has been turned on while an alarm operation is in progress, it stops the alarm operation.

[0029] Speaker 34 outputs sound when the main microcontroller 38 detects an abnormal condition (high concentration abnormality of the target gas) in the monitoring area based on the signal from the gas sensor 24. In this case, speaker 34 outputs an alarm sound and an alarm voice (alarm message). These alarm voices and other messages are stored in voice IC 40.

[0030] The light-emitting section 36 shown in Figure 6 emits light to notify the various states of the gas alarm 1 and is composed of eight LEDs (Light Emitting Diodes). These light-emitting sections 36 consist of a blue light-emitting section 36a that indicates the communication status, an orange light-emitting section 36b that indicates that an audio message or the like is being output (notification in progress), a yellow light-emitting section 36c that indicates an abnormal carbon monoxide concentration, a green light-emitting section 36d that indicates the power-on state, and a red light-emitting section 36e that indicates a gas leak in city gas. The light from these light-emitting sections 36 is output to the outside via a light guide plate (not shown) and a second lens 16 (see Figure 5).

[0031] The main microcontroller 38 shown in Figure 7 controls the entire gas alarm 1 and, in this embodiment, includes a communication setting unit 38a. In setting mode, the communication setting unit 38a configures the communication so that the communication module 28 is connected to an external server OS via a communication line. The external output unit 42 is an output unit for outputting a voltage signal, for example, via signal terminal D (see Figure 4).

[0032] Figure 8 is a partially enlarged cross-sectional view showing the internal configuration of the gas alarm 1 shown in Figures 1 to 7. As shown in Figure 8, the gas alarm 1 is equipped with a second lever member L2 connected to the back side of the lid 2b. The second lever member L2 is a cantilevered member extending toward the control board 22, and its tip is interposed between the push-button 10 and the communication switch 30. In particular, the second lever member L2 is positioned so as not to press the communication switch 30 when no external force is applied. The role of this second lever member L2 is to provide a click sensation when the push-button 10 is operated, and to prevent the push-button 10 from remaining pressed down (i.e., stuck down).

[0033] Next, an overview of the operation of the gas alarm 1 according to this embodiment will be described. Figure 9 is a first timing chart showing the operation of the gas alarm 1 according to this embodiment. First, as described above, the gas alarm 1 starts the confirmation mode when the push operation unit 10 (communication switch 30) is pressed for a specified time (for example, 3 seconds) while in a normal monitoring state, and starts the setting mode after the confirmation mode is completed. The gas alarm 1 also starts the confirmation mode when the power is turned on while the push operation unit 10 (communication switch 30) is pressed and the pressed state of the push operation unit 10 continues for a specified time (for example, 3 seconds), and starts the setting mode after the confirmation mode is completed. The setting mode has an automatic setting mode in which communication settings are performed automatically and a manual setting mode in which communication settings are performed manually. The communication setting unit 38a prioritizes starting the automatic setting mode when the setting mode is started. In other words, the communication setting unit 38a does not start the manual setting mode when the setting mode is started.

[0034] First, let's assume that the confirmation mode ended before time 0 as shown in Figure 9, and that the communication setting unit 38a started the setting mode at time 0. In this case, the main microcontroller 38 outputs an audio message from the speaker 34 indicating that the setting mode (automatic setting mode) has started. Specifically, the speaker 34 outputs the audio message, "Registration will begin. This is automatic setting mode." When the setting mode starts, the main microcontroller 38 starts the blue light-emitting unit 36a and the green light-emitting unit 36d to blink.

[0035] When the automatic setup mode is running, if the WPS (Wi-Fi Protected Setup) button (not shown) on the router R is pressed by a user or other person, the communication setting unit 38a automatically configures the communication between the router R and the communication module 28. At this time, the communication setting unit 38a registers the router R's SSID (Service Set Identifier) ​​and encryption key.

[0036] Assume that the communication setup is not complete at time t11, which is a first predetermined time (for example, 30 seconds) after time 0. In this case, the main microcontroller 38 outputs an audio message from speaker 34 indicating that it is in automatic setup mode. Specifically, speaker 34 outputs the message, "Automatic setup mode is active."

[0037] Next, let's assume that the communication setup is not complete at time t12, which is a first predetermined time (for example, 30 seconds) after time t11. In this case as well, the speaker 34 will output a voice message indicating that it is in automatic setup mode. Thus, the gas alarm 1 according to this embodiment periodically outputs a voice message indicating that it is in setup mode. This prevents users from becoming anxious when the communication setup is taking time, and clearly indicates that the communication setup is in progress.

[0038] Subsequently, at time t13, the communication setting unit 38a completes the communication setting. At this time, the main microcontroller 38 outputs an audio message from speaker 34 indicating that the communication setting is complete and an audio message indicating the communication strength. Specifically, speaker 34 outputs an audio message such as, "Registration complete. Communication strength is strong." Furthermore, prior to this audio output, the main microcontroller 38 outputs a notification sound (for example, a beep) from speaker 34. This prevents it from becoming difficult to understand that the communication setting is complete.

[0039] To explain in detail, in the example shown in Figure 9, at time t12, the voice message "Automatic setup mode in progress." is output. At time t13, when this voice output ends, the communication setup is complete. Therefore, if no notification sound is output, the user will hear the periodically outputted voice message "Automatic setup mode in progress." and the voice message "Registration complete. Communication strength is strong." output when the communication setup is complete, in succession. In other words, the user will hear the voice messages "Automatic setup mode in progress. Registration complete. Communication strength is strong." in succession, which may make it difficult for the user to hear. Therefore, by interposing a notification sound, speaker 34 will output "Automatic setup mode in progress. Beep. Registration complete. Communication strength is strong." In other words, the notification sound acts as a separator between the periodic voice message and the voice message when the communication setup is complete, making both voices easier to hear.

[0040] Next, at time t14, which is a second predetermined time (for example, 5 seconds) after time t13, the gas alarm 1 transitions to normal operation. The blue light-emitting part 36a is illuminated from time t13 to time t14.

[0041] Figure 10 is a second timing chart showing the operation of the gas alarm 1 according to this embodiment. Assume that at time 0 shown in Figure 10, the communication setting unit 38a starts setting mode. In this case, the main microcontroller 38 outputs an audio message from the speaker 34 indicating that setting mode (automatic setting mode) has started. Specifically, the speaker 34 outputs the audio message, "Registration will begin. This is automatic setting mode." When setting mode starts, the main microcontroller 38 starts flashing the blue light-emitting unit 36a and the green light-emitting unit 36d.

[0042] Next, let's assume that the communication settings are not complete at time t21, which is three predetermined times (for example, 2 minutes) after time 0. In this case, the main microcontroller 38 terminates the automatic setting mode and switches to manual setting mode. Then, the main microcontroller 38 outputs an alert sound from speaker 34, and then outputs a voice message from speaker 34 indicating that it is in manual setting mode. Specifically, speaker 34 outputs a "beep" alert sound, followed by the voice message, "In manual setting mode." From then on, as long as it is in manual setting mode, the main microcontroller 38 periodically outputs the voice message, "In manual setting mode."

[0043] In manual setup mode, the user connects a PC (Personal Computer), smartphone, tablet, or other device to the gas alarm 1 wirelessly or via a wired connection, and registers the SSID and encryption key by operating the control device. This manual setup mode continues for, for example, the fourth predetermined time (e.g., 15 minutes).

[0044] In manual setting mode, once the communication settings are complete, the same operations as those shown in Figure 9 from time t13 onwards are performed. On the other hand, suppose that the fourth predetermined time has elapsed and it is now time t22 without the communication settings being completed in manual setting mode. In this case, the main microcontroller 38 determines that a timeout has occurred and automatically terminates manual setting mode. When manual setting mode terminates, the main microcontroller 38 outputs a "beep beep beep" notification sound from the speaker 34, and then outputs an audio message indicating that the communication settings could not be completed, saying "Registration failed."

[0045] Next, at time t23, when the voice message indicating that communication settings could not be completed is finished, the gas alarm 1 switches to normal operation. From time t22 to time t23, the blue light-emitting part 36a flashes at a shorter interval than when in setting mode.

[0046] Thus, according to the gas alarm 1 and its control method as described in this embodiment, the speaker 34 outputs an audio message when the setting mode is started, and also periodically outputs an audio message indicating that the setting mode is in progress. This allows the user to be notified not only when the setting mode starts, but also when the setting mode is continuing. As a result, even if the communication setup takes time, the user will be periodically notified that the setting mode is in progress, making it less likely for them to become anxious, and it will also be easier to understand that the communication setup is in progress. Therefore, it is possible to reduce the possibility of causing anxiety to the user and make it easier for them to understand that the communication setup is in progress.

[0047] Furthermore, when communication settings are completed in setting mode, an audio message confirming completion is output, and a notification sound is output prior to the completion message. If the system periodically outputs an audio message indicating that it is in setting mode, depending on the timing of the completion of the settings, the audio message indicating that it is in setting mode and the audio message confirming completion may be output consecutively, making it difficult for the user to hear. However, by adding a notification sound, the distinction between the two audio messages becomes clearer, reducing the possibility of missing an important message. Therefore, the possibility of causing anxiety to the user due to missing an important message can be reduced.

[0048] Furthermore, if the setting is not completed even after the automatic setting mode has continued for a third predetermined time, the system automatically switches from the automatic setting mode to the manual setting mode. Therefore, for example, if the automatic setting mode was initially executed but the setting was not completed, there is no need to operate the gas alarm 1 to switch to the manual setting mode. In particular, the gas alarm 1 according to this embodiment is installed on the ceiling, and switching to manual mode would require considerable effort, such as using a stepladder. However, by switching automatically, the above effort is eliminated when switching to manual setting mode, thereby simplifying the setting process.

[0049] Although the present invention has been described above based on embodiments, the present invention is not limited to the above embodiments, and modifications may be made without departing from the spirit of the invention, and other technologies may be combined as appropriate to the extent possible.

[0050] For example, although the gas alarm 1 according to this embodiment has been described as an alarm for city gas where the reducing gas to be detected is methane gas, it is not limited to this, and may also be an alarm for LP gas where the gas to be detected is propane gas or butane gas, etc. Furthermore, the gas alarm 1 may be configured as a gas fire alarm that also has a fire alarm function. In addition, the gas alarm 1 according to this embodiment is not limited to a ceiling-mounted type, but may also be a stationary alarm installed in other locations such as near the ceiling or on the wall at floor level.

[0051] Furthermore, the gas alarm 1 according to this embodiment periodically outputs a voice message indicating that it is in setting mode, but this is not limited to outputting the voice message at a single time interval. That is, although the above describes outputting a voice message indicating that it is in automatic setting mode every first predetermined time (for example, 30 seconds), it is not limited to this, and for example, the voice message indicating that it is in automatic setting mode may be output every 10 seconds (first time interval) for the first minute (within a specific time from the start of setting mode), and then every 20 seconds (second time interval) thereafter (after a specific time from the start of setting mode). Alternatively, the first voice message may be set to the first time interval, the second voice message to the second time interval, and so on, with the time intervals alternating. In addition, the voice message indicating that it is in setting mode may be output completely randomly or irregularly, such as with gradually shortening time intervals. [Explanation of Symbols]
