  Exemplary embodiments of an alarm device, a control method for the alarm device, and a control program according to the present invention will be described below in detail with reference to the accompanying drawings. In the following, the alarm system using the alarm device according to the present invention is taken as an example, and after describing the outline and features of the alarm system according to the present example, the configuration of the alarm device (appearance configuration, internal configuration), the present Processing (detection alarm processing, alarm stop processing) by the alarm system of the embodiment will be described, and finally various modifications to the present embodiment will be described.

[1: Outline and features of alarm system]
First, the outline and features of the alarm system according to the present embodiment will be described with reference to FIG. FIG. 1 is a system configuration diagram illustrating an overall configuration of an alarm system according to the present embodiment.

  As illustrated in FIG. 1, the alarm system according to the present embodiment includes alarm devices 10 respectively installed in relatively small monitoring areas such as a kitchen, a bedroom, and a living room of an ordinary house, and a room of an office. The interlocking lead wires 9 are connected so as to be communicable with each other. In such an alarm system, each alarm device 10 generally detects not only a fire or gas that has occurred in the monitoring area and issues an alarm signal to other alarm devices 10 in addition to alarming itself. At the same time, an alarm signal is received from another alarm device 10 to perform a linked alarm.

  That is, as shown in FIG. 1, an alarm system in which alarm devices 10 are installed and wired in the 1F kitchen (address A), 1F living room (address B), and 2F bedroom (address C, address D) of a general house, respectively. For example, when the alarm device 10 in the 1F kitchen detects a fire, the alarm device 10 not only emits an alarm light and an alarm sound, but also transmits an alarm signal to the alarm devices 10 in the 1F living room and 2F bedroom. The alarms 10 in the living room and bedroom (the alarms 10 at addresses B, C, and D) that have received the signal similarly generate an alarm sound.

  The main feature of the alarm system of this outline is that, as briefly listed below, the user at the interlocking destination can take an immediate response to the abnormality at the interlocking source. is there. In this embodiment, the monitoring area (1F kitchen in the above example) where the alarm device 10 that transmits the alarm signal is called “link source”, and the alarm device 10 that receives the alarm signal and issues the link alarm is called A certain monitoring area (in the above example, 1F living room and 2F bedroom) will be referred to as a “link destination”.

  In other words, in this embodiment, each alarm device 10 outputs a voice message that is output as a linked alarm when an alarm signal is received from the other alarm device 10 for each address that uniquely identifies a plurality of other alarm devices 10. Are stored in association with each other. When an alarm signal with an address is received from another alarm device 10, a voice message corresponding to the address is read and output.

  To give a specific example, when the alarm 10 installed in the first floor kitchen is the interlocking source, a voice message such as “Alarm activated in the first floor kitchen” is output at the interlocking destination. When the alarm device 10 installed between the floors is the link source, a voice message such as “Alarm has been activated between the floors 1st floor” is output at the link destination. As a result, the user at the interlocking destination can easily grasp which alarm device 10 issued as the interlocking source, and can take an immediate response to the abnormality of the interlocking source.

  Further, in this embodiment, each alarm device 10 transmits an alarm signal including an abnormality type indicating which abnormality is detected in fire or gas to the other alarm devices 10. Each alarm device 10 stores, for each combination of address and abnormality type, a voice message that is output as a linked alarm when an alarm signal of the combination is received, and stores the address and abnormality from the other alarm devices 10. When an alarm signal including a type is received, a voice message corresponding to the address and the abnormal type is read and output.

  To give a specific example, when the first floor kitchen alarm 10 detects a gas and issues a gas alarm, a voice message such as “The gas alarm has been activated in the first floor kitchen” is output at the link destination. In addition, when the alarm device 10 in the first floor living area detects a fire and issues a fire alarm, a voice message such as “The fire alarm has been activated in the first floor living room” is output at the interlocking destination. As a result, the user at the interlocking destination can easily grasp what kind of abnormality the alarm device 10 has detected and issued.

  Further, in the present embodiment, each alarm device 10 transmits an alarm signal including an alarm level indicating which level of the alarm has occurred in the pre-alarm level or the main alarm level to the other alarm devices 10. To do. Each alarm device 10 stores, for each combination of address and alarm level, a voice message that is output as a linked alarm when an alarm signal of the combination is received, and stores the address and alarm level from other alarm devices. When an alarm signal including is received, a voice message corresponding to the address and alarm level is read and output.

  For example, when the first floor kitchen alarm 10 detects a pre-alarm level fire and issues a fire pre-alarm, a voice message such as "Fire pre-alarm activated in the first floor kitchen" When the alarm on the 1st floor kitchen detects a fire of this alarm level and issues a fire main alarm, a voice such as “The fire main alarm has been activated in the 1st floor kitchen” is output. Output the message at the link destination. As a result, the user at the link destination can easily grasp which alarm device has issued at what level.

  Further, in this embodiment, each alarm device 10 is interlocked when an alarm signal is received from a plurality of other alarm devices 10 constituting the combination for each combination of a plurality of addresses related to the other alarm devices 10. A voice message to be output as an alarm is stored in association with it. And when the alarm signal with an address is received from several other alarm devices 10, the voice message corresponding to the combination of the said address is read and output.

  For example, when a fire alarm signal is received from the alarm device 10 on the first floor kitchen and a fire alarm signal is also received from the alarm device 10 on the first floor (in such a case) , It is highly probable that the entire first floor will be a fire without checking the status of each link source.) Will output a voice message such as “The first floor is a fire” at the link destination. . As a result, the user at the link destination can comprehensively grasp the situation of the plurality of link sources. Furthermore, the voice message enables the user at the link destination to take a more appropriate response to the link source abnormality, for example, immediately evacuating without confirming the status of the link source. .

A locking portion 3 having a hole 4 is integrally formed. And the alarm device 10 is installed by inserting the attachment hole 4 of the latching | locking part 3 with respect to the screw 5 attached to the wall surface of the monitoring area | region.

  In addition, a fire detection unit (chamber accommodating unit) 11 protruding in a dish shape is formed on the top of the front cover 1, and a plurality of smoke inlets are provided around the fire detection unit 11. Further, a gas detector 12 for detecting gas (CO) is provided at the upper corner of the front cover. A fire alarm lamp 6, a gas alarm lamp 7 and a speaker 8 for outputting a fire alarm or a gas alarm are formed below the front cover 1.

  An inspection switch 13 used for alarm inspection and alarm stop is formed in the lower part of the alarm device 10 body, and further, alarm signals and the like are transmitted / received to / from other alarm devices 10 from the inside of the alarm device 10. An interlocking lead wire 9 is drawn out. The alarm device 10 is not limited to a battery built-in as a power source, but may be a so-called AC power source, and in the latter case, a plug for receiving power from the power line. Is pulled out from the bottom surface of the housing.

  The interior of the alarm device 10 having such an appearance, as illustrated in FIG. 4, includes a fire detection unit 11, a gas detection unit 12, an inspection switch 13, a display output unit 14, an audio output unit 15, The interlocking transmission / reception unit 16, a storage unit 17, and a control unit (CPU) 20 are provided. The storage unit 17 corresponds to “message storage unit” described in the claims, and the control unit 20 also corresponds to “linked alarm processing unit” and “control unit”.

  Among these, the fire detection unit 11 is a processing unit that detects the occurrence of a fire in the monitoring area. Specifically, the concentration of smoke generated at the time of fire is detected using an infrared LED and a photodiode, and a detection signal composed of the numerical value is output to the control unit 20. Note that the smoke density sensing method is not necessarily limited to photoelectric sensing, and other methods such as so-called ionization sensing may be arbitrarily employed.

  The gas detection unit 12 is a processing unit that detects the generation of CO gas in the monitoring region. Specifically, when gas is detected by the gas detection element, a detection signal composed of the numerical value is output to the control unit 20.

  The inspection switch 13 is a means for accepting alarm inspection or alarm stop. Specifically, when the inspection switch 13 is pulled at the time of monitoring, the control unit 20 outputs a warning for inspection from the fire alarm lamp 6, the gas alarm lamp 7 and the speaker 8, and the inspection switch 13 is pulled at the time of alarm output. When the control is performed, the control unit 20 controls to stop the output of the sound alarm from the speaker 8 and transmits an alarm stop command (signal) to the other alarm devices 10.

  The fire alarm lamp 6 and the gas alarm lamp 7 are indicator lamp means such as a red LED that notifies the surroundings of an abnormality detection state by the alarm device 10 by lighting or blinking based on the control of the display output unit 14. The display output unit 14 is a processing unit that turns on or blinks the fire alarm lamp 6 and the gas alarm lamp 7 in accordance with an instruction from the control unit 20. The specific processing content of the display output unit 14 will be described later as processing content of the control unit 20.

  The speaker 8 is means for notifying the surroundings of the abnormality detection state and the interlocking state by the alarm device 10 by outputting a voice message and a buzzer sound to the monitoring area based on the control of the voice output unit 15. The voice output unit 15 then sends a voice message via the speaker 8 in response to an instruction from the control unit 20 when a fire is detected or when a gas is detected, or when an alarm signal is received from another alarm device 10. And a buzzer sound. The specific processing content of the audio output unit 15 will also be described later as processing content of the control unit 20.

  The interlocking lead wire 9 is a connection means for connecting the alarm device 10 and another alarm device 10 so that they can communicate with each other. The interlocking transmission / reception unit 16 transmits an alarm signal or an alarm stop signal to the other alarm device 10 via the interlocking lead wire 9 in response to an instruction from the control unit 20, while the alarm signal is output from the other alarm device 10. It is a processing unit that receives a signal and an alarm stop signal. The alarm signal includes an “address” of the alarm device 10 that is a source (link source) of the alarm signal, an “abnormality type” that indicates which type of abnormality is detected in fire or gas, and It is configured to include an “alarm level” that indicates which level of alarm has occurred in the pre-alarm level or the main alarm level.

  The storage unit 17 is a storage unit (storage unit) that stores data and programs necessary for various processes performed by the control unit 20, and particularly those closely related to the present invention include those shown in FIGS. As illustrated in FIG. 8, a detection processing table 17a, an alarm processing table 17b, and an interlocking processing table 17c are provided.

  Among these, the detection processing table 17 a is a means for storing information used for detection processing by the control unit 20. Specifically, as illustrated in FIG. 5, it is classified into a plurality of abnormality types such as fire and gas, and a plurality of alarm levels such as a pre-alarm level and a main alarm level, and is used for determining the occurrence of an abnormality at each alarm level. A threshold value (threshold value) is stored.

  The alarm processing table 17b is means for storing information used for alarm processing by the control unit 20. Specifically, as illustrated in FIG. 6, it is divided into a plurality of abnormality types such as fire and gas, and a plurality of alarm levels such as a pre-alarm level and a main alarm level (and a pre-alarm level at the time of interlocking). The contents of the alarm processing to be executed when an abnormality occurs at each alarm level are stored. In this figure, “single detection” defines the conditions when either fire or gas is detected, and “combined detection” refers to the conditions when both fire and gas are detected. It is specified.

  Furthermore, the interlocking process table 17c is a means for storing information used for interlocking processing (processing when an alarm signal is received from another alarm device 10) by the control unit 20. Specifically, as illustrated in FIG. 7 and FIG. 8, the alarm is classified into a plurality of alarm types such as an address of another alarm device 10, a plurality of abnormality types such as fire and gas, and a pre-alarm level and a main alarm level. Thus, a voice message output when an alarm signal corresponding to each address, abnormality type and alarm level is received is stored.

  The interlocking processing table 17c illustrated in FIG. 8 defines a voice message that is output when an alarm signal is received from a plurality of other alarm devices 10 at the same time. When the alarm signal is received at the same time, the interlocking process table 17c has priority over the interlocking process table 17c illustrated in FIG.

  Returning to FIG. 4, the control unit 20 has a control program such as an OS (Operating System), a program defining various processing procedures, and an internal memory for storing necessary data. The processing unit to be executed, particularly those closely related to the present invention, includes a detection processing unit 20a, an alarm processing unit 20b, and an interlocking processing unit 20c. The interlocking processing unit 20c corresponds to “interlocking alarm processing means” described in the claims.

  Among these, the detection processing unit 20a is a processing unit that determines the occurrence of fire and gas generation based on detection signals (smoke concentration and gas concentration) input from the fire detection unit 11 and the gas detection unit 12. Specifically, when a detection value is input from the fire detection unit 11 or the gas detection unit 12, it is compared with a threshold value stored in the detection processing table 17a, and if the pre-alarm level threshold value is exceeded. If a pre-alarm signal (fire or gas pre-alarm signal) is output to the alarm processing unit 20b and the interlock processing unit 20c and the alarm level threshold is exceeded, the alarm processing unit 20b and the interlock processing unit 20c are pre-alarmed. Outputs a signal (fire or gas alarm signal).

  More specifically, as illustrated in FIG. 5, when a detection signal (smoke density) is input from the fire detection unit 11, first, the ambient smoke density has reached 5 (% / m) or more. After exceeding this, it is determined whether the surrounding smoke density has reached 10 (% / m) or more. When a detection signal (gas concentration) is input from the gas detection unit 12, first, it is determined whether or not the surrounding gas concentration has reached 150 (ppm) or more. Then, it is determined whether or not the surrounding gas concentration has reached 300 (ppm) or more.

  When the inspection switch 13 is pulled during monitoring, the detection processing unit 20a generates a test signal (a signal similar to the detection signal of the fire detection unit 11 or the gas detection unit 12), and a fire occurs based on the test signal. In the case where the presence or absence of gas is determined in a pseudo manner and it is determined that a fire or gas has occurred, an alarm signal is output to the alarm processing unit 20b in the sense that it can operate normally. The alarm processing unit 20b to which the alarm signal is input outputs an inspection alarm from the fire alarm lamp 6, the gas alarm lamp 7, and the speaker 8.

  The alarm processing unit 20b is a processing unit that issues a fire or gas generation alarm based on an alarm signal from the detection processing unit 20a. Specifically, when an alarm signal (fire pre-alarm signal, CO pre-alarm signal, fire main alarm signal or CO main alarm signal) is input from the detection processing unit 20a, the alarm stored in the alarm processing table 17b is stored. By controlling the display output unit 14 and the audio output unit 15 so as to execute the processing contents, a predetermined audio message and buzzer sound are output from the speaker 8 and the fire alarm lamp 6 and the gas alarm lamp 7 are turned on or Blink.

  More specifically, as illustrated in FIG. 6, when only the fire pre-alarm signal is input from the detection processing unit 20 a, the alarm processing unit 20 b blinks the fire alarm lamp 6 and “Pupe A warning sound with a voice message saying “Please confirm” is output from the speaker 8 at 65 db. In addition, when only the fire main alarm signal is input from the detection processing unit 20a, the fire alarm lamp 6 is turned on and an alarm with a voice message “Please confirm that the fire alarm device has been activated” is issued. Sound is output from the speaker 8 at 80 db.

  Furthermore, even when a fire pre-alarm signal is input from the detection processing unit 20a in a situation where an alarm signal is received from another alarm device 10, the fire alarm lamp 6 is turned on without waiting for this alarm. The speaker 8 outputs an alarm sound with a voice message “Please confirm that the fire alarm has been activated (80 db)”. In other words, in such a case, it is highly likely that a fire at this alarm level will be detected directly, so the same alarm processing is performed without waiting for this alarm to ensure safety (fail safe). This is the purpose.

  In addition, as illustrated in the figure, when only the CO pre-alarm signal is input from the detection processing unit 20a, the gas alarm lamp 7 is blinked and a voice message “Poopup air is dirty” is attached. Is output from the speaker 8 at 65 db. If only the CO main alarm signal is input from the detection processing unit 20a, the gas alarm lamp 7 is turned on, and a voice message “Open the window and ventilate because the air is dirty and dangerous” is displayed. The attached alarm sound is output from the speaker 8 at 80 db.

  Further, even when the alarm signal is received from another alarm device 10 and the CO pre-alarm signal is input from the detection processing unit 20a, the gas alarm lamp 7 is turned on without waiting for this alarm. The speaker 8 outputs an alarm sound with a voice message “Open the window and ventilate (80 db)”. In other words, as in the case of the fire pre-alarm at the time of interlocking described above, in this case, it is considered that there is a high possibility that the gas at this alarm level will be detected directly. Therefore, the same alarm processing is performed without waiting for this alarm. To ensure safety (fail-safe).

  Further, as illustrated in the figure, when the fire pre-alarm signal and the CO pre-alarm signal are input from the detection processing unit 20a, the fire alarm lamp 6 and the gas alarm lamp 7 are turned on, and “PP fire An alarm sound with a voice message “It is a fire” is output from the speaker 8 at 80 db. In other words, if a fire pre-alarm signal and a CO pre-alarm signal are input, it is considered that there is a high possibility of a fire occurring, so fire alarm processing should be performed without waiting for the fire main alarm signal. The purpose is to ensure safety (fail-safe).

  When the alarm processing unit 20b receives an alarm stop command (pressing the inspection switch 13 or receiving an alarm stop signal from another alarm device 10) after the alarm output by the alarm process is started, In the alarm process, only the voice alarm is stopped. That is, the alarm sound with the voice message output from the speaker 24 is stopped while the lighting or blinking of the fire alarm lamp 6 and the gas alarm lamp 7 is maintained.

  The interlocking processing unit 20c is a processing unit that transmits an alarm signal to another alarm device 10 based on the alarm signal from the detection processing unit 20a. Specifically, when an alarm signal (fire pre-alarm signal, CO pre-alarm signal, fire main alarm signal, or CO main alarm signal) is input from the detection processing unit 20a, its own address (for example, FIG. By adding the address A and the like illustrated in (1), an “address” indicating a source (interlocking source) of an alarm signal, an “abnormality type” indicating a fire or gas, and a pre-alarm level or a main alarm level “ An alarm signal consisting of “alarm level” is generated and transmitted from the interlocking transmission / reception unit 16 to another alarm device 10.

  The interlocking processing unit 20 c is also a processing unit that performs an interlocking alarm based on an alarm signal received from another alarm device 10 via the interlocking transmission / reception unit 16. Specifically, when an alarm signal with an address (fire pre-alarm signal, CO pre-alarm signal, fire main alarm signal or CO main alarm signal) is input from the interlocking transmission / reception unit 16, the audio output unit 15 is controlled. Thus, the corresponding voice message stored in the interlocking processing table 17c is output from the speaker 8.

  More specifically, the alarm device 10 at the address C (second-floor bedroom) illustrated in FIG. 1 will be described as an example. The interlock processing unit 20c of the alarm device 10 includes an address A as illustrated in FIG. If only the fire pre-alarm signal is received, a voice message “fire pre-alarm has been activated in the first floor kitchen” is output from the speaker 8 at 65 db. When only the fire main alarm signal of address A is received, a voice message “Please confirm that the fire main alarm has been activated in the kitchen on the first floor” is output from the speaker 8 at 80 db.

  On the other hand, as illustrated in the figure, when only the fire pre-alarm signal of address B is received, a voice message “fire pre-alarm has been activated in the first floor living room” is output from the speaker 8 at 65 db. If it is output, and only the fire main alarm signal of address B is received, a voice message “Please confirm that the fire main alarm has been activated in the first floor living room” is output from the speaker 8 at 80 db. . In other words, the user at the interlocking destination can easily understand which alarm device 10 has issued the alarm as the interlocking source.

  Also, as illustrated in the figure, when only the CO pre alarm signal of address A is received, a voice message “CO pre alarm has been activated in the first floor kitchen” is output from the speaker 8 at 65 db. If only the CO main alarm signal of address A is received, a voice message “Please confirm that the CO main alarm has been activated in the kitchen on the first floor” is output from the speaker 8 at 80 db. In other words, it is intended to make it easy for the user at the interlocking destination to know which abnormality is detected and which alarm device 10 has issued.

  Furthermore, as illustrated in the figure, when the fire pre-alarm signal and the CO pre-alarm signal of address A are received at the same time, the voice message “It is a fire in the first floor kitchen” is 80 db. Output from the speaker 8. In other words, if a fire pre-alarm signal and a CO pre-alarm signal with the same address are received, it is considered that there is a high possibility of a fire occurrence. The purpose is to ensure safety (fail-safe) by outputting a voice message immediately.

  In addition, as illustrated in FIG. 8, when the fire pre-alarm signal or CO pre-alarm signal at address A and the fire pre-alarm signal or CO pre-alarm signal at address B are received at the same time, A voice message “The first floor is a fire is a fire” is output from the speaker 8 at 80 db. In other words, in such a case, it is considered that there is a high possibility that the entire first floor is a fire, without checking the status of each link source (monitoring area of address A and address B). By outputting a voice message such as “The first floor is a fire” instead of a voice message that prompts the original confirmation, it is possible for the users at the linkage destination to comprehensively understand the status of multiple linkage sources. This is the purpose.

[3: Detection alarm processing]
Next, detection alarm processing by the alarm system of the present embodiment will be described. FIG. 9 is a flowchart showing the flow of detection alarm processing according to the present embodiment.

  In FIG. 9, the alarm device 10 at the address A detects an abnormality and transmits an alarm signal to the alarm devices 10 at the addresses B, C, and D, but the address B, C, or A similar process is executed when the D alarm device 10 detects an abnormality. In addition, in the same figure, among the alarm devices 10 at the addresses B, C, and D that have received the alarm signal, the processing of the alarm device 10 at the address C is given as an example. A similar process is executed.

  As illustrated in FIG. 9, when the detection value (smoke concentration or gas concentration) is input from the fire detection unit 11 or the gas detection unit 12 to the alarm device A (the alarm device 10 at the address A) (Yes in step S901). Then, it is determined whether or not the detected value exceeds the threshold concentration stored in the detection processing table 17a (step S902).

  Specifically, as illustrated in FIG. 5, when a detection signal (smoke concentration) is input from the fire detection unit 11, first, it is determined whether or not the smoke concentration at the pre-alarm level has been reached. After this is exceeded, it is determined whether or not the smoke concentration at this alarm level has been reached. Also, when a detection signal (gas concentration) is input from the gas detection unit 12, it is first determined whether or not the gas concentration of the pre-alarm level has been reached. It is determined whether or not the gas concentration is reached.

  If the detected value does not exceed any alarm level threshold (No at Step S902), the alarm device A returns to the process at Step S901 and waits for the input of the next detected value (Step S901). ). On the other hand, when the detected value exceeds the threshold value of one of the alarm levels (Yes at step S902), the alarm device A executes an alarm process (step S903).

  Specifically, as illustrated in FIG. 6, corresponding alarm processing is performed depending on which abnormality type exceeds which alarm level threshold. For example, a pre-alarm level threshold is set only for a fire. If it exceeds, the fire alarm lamp 6 blinks and an alarm sound with a voice message “Please check the origin of the fire” is output from the speaker 8 at 65 db.

  As an example, as illustrated in the figure, when a warning signal is received from another alarm device 10 and the pre-alarm level threshold is exceeded only for a fire, the fire alarm lamp 6 is turned on. Turns on the light and outputs an alarm sound with a voice message “Check that the fire alarm has been activated (80 db)” from the speaker 8.

  For example, as illustrated in the figure, when the pre-alarm level threshold is exceeded for the fire and the pre-alarm level threshold is also exceeded for the gas, the fire alarm lamp 6 and the gas alarm lamp 7 are used. Is turned on, and an alarm sound with a voice message “Pip is a fire” is output from the speaker 8 at 80 db.

  The alarm device A executes such alarm processing and transmits an alarm signal to the other alarm devices 10 (the alarm devices 10 at addresses B, C, and D) (step S904). Specifically, depending on which abnormality type exceeds which alarm level threshold, “abnormality type” indicating fire or gas, “alarm level” indicating pre-alarm level or main alarm level, and alarm signal For example, when a pre-alarm level threshold value is exceeded for a fire, a fire pre-alarm signal is transmitted with an address A.

  Then, the other alarm device 10 that has received the alarm signal performs an interlocking alarm based on the received alarm signal (step S905). Specifically, as illustrated in FIG. 7 and FIG. 8, each corresponding alarm processing is performed according to which alarm level is received for which abnormality type from which address, When only the fire pre-alarm signal at address A is received, the alarm C outputs a voice message from the speaker 8 at 65 db that “the fire pre-alarm has been activated in the kitchen on the first floor”.

  As an example, if the alarm device C receives only the fire pre-alarm signal at address B, as illustrated in the figure, the fire pre-alarm has been activated in the first floor living room. A voice message is output from the speaker 8 at 65 db. For example, when the alarm device C receives the fire pre-alarm signal at address A and the fire pre-alarm signal at address B at the same time as illustrated in FIG. A voice message “The floor is a fire” is output from the speaker 8 at 80 db.

  Thereafter, each alarm device 10 (each alarm device 10 at addresses A, B, C, and D) returns to the process of step S901 and waits for the input of the next detection value (step S901). That is, if the alarm process executed in S903 is a pre-alarm level process, it waits for the input of a further detected value, and determines whether the detected value has reached the threshold of this alarm level. To do.

[4: Alarm stop processing]
Next, alarm stop processing by the alarm system of this embodiment will be described. FIG. 10 is a flowchart showing the flow of alarm stop processing according to this embodiment.

  In FIG. 10, in a situation where each alarm device 10 at addresses A, B, C, and D performs an alarm or a linked alarm, the alarm device 10 at address C accepts an alarm stop command, and addresses A, B, and D Although the case where an alarm stop signal is transmitted to the alarm device 10 is taken as an example, the same processing is executed when the alarm device 10 at the address A, B or D receives an alarm stop command. In the same figure, among the alarm devices 10 at addresses A, B, and D that have received the alarm stop signal, the processing of the alarm device 10 at address A is given as an example. The same processing is executed in step.

  As illustrated in FIG. 10, the alarm device C (the alarm device 10 at the address C), when the inspection switch 13 is pulled at the time of alarm output (Yes in step S1001), indicates that an alarm stop command has been received, Only the voice alarm is stopped (step S1002). That is, the alarm sound with the voice message output from the speaker 8 is stopped while the fire alarm lamp 6 and the gas alarm lamp 7 are kept on or blinking.

  The alarm device C not only stops its own voice alarm, but also issues an alarm stop command (signal) to another alarm device 10 (the alarm device 10 at the address A, B or D) via the interlocking lead wire 9. Is transmitted (step S1003). And the other alarm device 10 which received this alarm stop command also stops only an audio | voice alarm among alarm processes (step S1005).

  Thereafter, in each alarm device 10 (alarm devices 10 at addresses A, B, C, and D), the voice alarm stop is held for a predetermined time, and when the predetermined time elapses (Yes in Step S1004, Yes in Step S1006), the above-described diagram. The process returns to step S901 in FIG. 9 to wait for input of the next detection value (step S901 in FIG. 9). That is, the voice alarm stop is not maintained permanently, but monitoring is resumed after a predetermined time, and if a fire or gas is detected again, alarm processing is similarly performed.

  As described above, even when a plurality of alarm devices 10 each output a sound alarm due to the interlocking alarm, if the user performs an alarm stop operation on any of the alarm devices 10, the sound alarms of all the alarm devices 10 are displayed. Therefore, the user does not need to perform an alarm stop operation on each of the alarm devices 10 and can easily stop the sound alarms of all the alarm devices 10.

  In addition, although the example which stops the audio | voice alarm of all the alarm devices 10 here was demonstrated easily, when abnormality is detected in the self-monitoring area | region, an alarm output is continued, without stopping an audio | voice alarm. May be. As a result, at least in the monitoring area where the abnormality is detected by itself, the alarm is continuously output, so that it is possible to secure further safety.

[5: Other embodiments]
Although the embodiments of the present invention have been described so far, the present invention may be implemented in various different forms other than the embodiments described above. Therefore, as shown below, (1) Other processing contents, (2) Other abnormalities, (3) Other detection methods, (4) Other interlocking alarm methods, (5) Other configurations, etc. Another embodiment will be described by dividing.

(1) Other process contents The contents of the detection process, the alarm process, and the interlocking alarm process (see FIGS. 5 to 8) described in the above embodiment are merely examples, and the present invention is not limited to this. The present invention can be similarly applied even when other processing different from this is performed.

  For example, in the above embodiment, location information (first floor kitchen, first floor living room, second floor bedroom, etc.) for specifying a monitoring area where another alarm device 10 is installed is included as the contents of the linked alarm processing. However, the present invention is not limited to this, for example, “the alarm device at address 1 is activated”, “the alarm device at address 2”. For example, a voice message including information that can uniquely identify an alarm device among a plurality of alarm devices may be stored and output.

  In the above embodiment, the case where different threshold values are used for the pre-alarm level and the main alarm level is described as the content of the detection process (see FIG. 5), but the present invention is not limited to this. For example, at the pre-alarm level of a fire, it is determined whether or not the ambient smoke density has reached 10 (% / m) or more over an accumulation time of 30 seconds. For example, it may be determined whether or not the value has reached 10 (% / m) or more over a second accumulation time, and the detection process may be performed by changing the accumulation time instead of the threshold value.

  In the above embodiment, the case where two alarm levels, the pre-alarm level and the main alarm level, are used has been described. However, the present invention is not limited to this, and of course, when more alarm levels are used. Even when only a single alarm level is employed, the present invention can be similarly applied.

  Further, in the above-described embodiment, the case where an alarm that clarifies the abnormal type of fire or gas has been described as the contents of the alarm process and the interlock alarm process (see FIGS. 6 to 8), but the present invention is based on this. For example, after identifying the type of fire and outputting a voice message such as “This is a flame fire” or “This is a fire that burns” Different alarm processing may be performed depending on the detailed type.

  In the above embodiment, the contents of the detection process, the alarm process, and the interlocking alarm process are not necessarily the same for each alarm device 10 (each alarm device 10 illustrated in FIG. 1), and each alarm device 10 is installed. Each alarm device 10 may perform different detection processing, alarm processing, and interlocking alarm processing in consideration of the monitored area and the characteristics of the user in the monitoring area. For example, it is considered that the distance between the monitoring areas is different between when the alarm device 10 at the address B receives an alarm signal from the address A and when the alarm device 10 at the address C receives an alarm signal from the address A. Then, different voice messages may be output.

  The contents of the detection processing table 17a, the alarm processing table 17b, and the interlocking alarm processing table 17c are used in the monitoring area via a setting button (not shown) provided in each alarm device 10. It is memorized through the setting operation by the person who installs the person or the alarm device 10.

(2) Other abnormalities In the above embodiment, the case where the present invention is applied to the alarm device 10 that detects abnormalities such as fire (smoke) and gas (CO) has been described. However, the present invention is not limited thereto. Rather than an alarm 10 that detects fire and gas leaks (hydrocarbon gas), an alarm 10 that detects fire, CO gas and hydrocarbon gas, an alarm 10 that detects only fire, an alarm that detects only gas The same can be applied to the vessel 10 and the like.

  Further, the present invention is not limited to the case where the present invention is applied to the alarm device 10 that detects an abnormality such as a fire or gas, but an abnormality signal (for example, intrusion) in the monitoring area is detected and an alarm signal is sent to another alarm device 10. The present invention can be similarly applied to any alarm device 10 that transmits.

  Further, the present invention is not limited to the alarm device 10 that transmits an alarm signal to another alarm device 10 to perform an interlocking alarm, and an abnormal signal related to an inspection abnormality is also transmitted to the other alarm device 10 and the abnormality is detected. The alarm device 10 that has received the signal may output a voice message indicating that an inspection abnormality has occurred in the other alarm device 10.

  In other words, for example, even when an abnormality is found in the contamination inspection of the sensor of the fire detection unit 12, by transmitting an abnormality signal to the other alarm devices 10, However, a voice message indicating an abnormal inspection may be output. As a result, the user at the linkage destination can also grasp the inspection abnormality that has occurred in the alarm device 10 at the linkage source. Such inspection abnormalities are less urgent than fire and gas warning signals, so it is not always necessary to output a voice message in real time. It may be output after waiting for the user's operation (pressing a predetermined button).

(3) Other detection methods In the above-described embodiment, the case where a fire is detected from smoke generated by a fire has been described. However, the present invention is not limited to this. A fire may be detected using a factor other than smoke instead (or together) such as detecting the presence or absence.

  That is, for example, in the fire pre-alarm level, it is determined whether or not the ambient temperature has reached 50 ° C. or higher. In the fire main alarm level, it is determined whether or not the ambient temperature has reached 60 ° C. or higher. A fire occurrence detection process may be executed using a different threshold temperature in each mode, such as determination.

  For example, at the fire pre-alarm level, a constant temperature type determination (determines whether the ambient temperature has reached a predetermined temperature or more) is performed, and at the fire main alarm level, a differential type determination ( It is also possible to determine whether or not the ambient temperature increase rate has become equal to or greater than a predetermined temperature increase rate, and execute the fire detection process.

  Furthermore, for example, in a fire pre-alarm level, in a certain fire mode 1, a constant temperature type determination is performed, and in a fire main alarm level, a compensation type determination (whether the ambient temperature has reached a predetermined temperature or more, Alternatively, it may be determined whether or not the ambient temperature increase rate is equal to or higher than a predetermined temperature increase rate, and the fire occurrence detection process may be executed.

(4) Other interlocking alarm methods In the above embodiment, the case where the interlocking alarm is performed by outputting a voice message from the speaker 8 in the interlocking destination alarm device 10 has been described, but the present invention is limited to this. Instead, for example, an interlocking alarm may be performed together with a voice message by turning on or blinking a predetermined alarm lamp (interlocking fire alarm lamp or interlocking gas alarm lamp).

  Further, a display unit such as a liquid crystal screen may be provided in the alarm device 10 and a display message may be displayed on the display unit in addition to (or instead of) the voice message. Further, for a hearing impaired person, a flash light may be provided, and lighting or blinking of the flash light may be combined with output of a display message by the display unit. Moreover, you may make it output combining an audio | voice message and a display message suitably with the alarm device 10. FIG.

  Note that it is not always necessary to output a voice message in conjunction with the interlocking alarm. For example, by providing a plurality of interlocking fire alarm lamps or interlocking gas alarm lamps for each address of the other alarm devices 10, The interlocking alarm may be performed only by blinking.

(5) Other Configurations The components of the alarm device 10 shown in FIGS. 2 to 4 are functionally conceptual, and need not be physically configured as illustrated. In other words, the specific form of distribution / integration of each part is not limited to the one shown in the figure, and all or a part thereof may be functionally or physically distributed / integrated in arbitrary units according to various loads and usage conditions. Can be configured.

  For example, in the above embodiment, the case where each alarm device 10 is communicably connected using the interlocking lead wire 9 has been described, but the present invention is not limited to this, and for example, radio waves, weak radio waves Alternatively, each alarm device 10 may be connected to be communicable wirelessly by using infrared rays, ultrasonic waves, or the like.

  In the above embodiment, the case where the present invention is applied to a wall-mounted fire alarm device has been described. However, the present invention is not limited to this, and the ceiling-mounted alarm device other than the wall-mounted alarm device is also used. The present invention can be similarly applied.

  Furthermore, each processing function performed by the alarm device 10 does not necessarily have to be realized by a CPU and a program that is analyzed and executed by the CPU. It may be realized as.

  In addition, among the processes described in the above embodiments, all or part of the processes described as being performed automatically can be manually performed, or the processes described as being performed manually. All or a part of the above can be automatically performed by a known method. In addition, the processing procedure, control procedure, specific name, and information including various data and parameters (especially information specified in each table) shown in the above documents and drawings are optional unless otherwise specified. Can be changed.
