  Hereinafter, preferred embodiments of a fire receiver according to the present invention will be described with reference to the drawings.

Embodiment 1 FIG.
First, functions of the fire receiver other than the emergency telephone call function will be described.
FIG. 1 is an overall configuration diagram of a fire alarm system according to Embodiment 1 of the present invention. The fire alarm system shown in FIG. 1 includes a fire receiver 10, four terminal devices 20 (1) to 20 (4), and a repeater 30. Here, the two terminal devices 20 (1) and 20 (2) and the repeater 30 are directly connected to the fire receiver 10. The two terminal devices 20 (3) and 20 (4) are directly connected to the repeater 30, and are connected to the fire receiver 10 via the repeater 30. The numbers of the terminal devices 20 and the repeaters 30 are not limited to the example of FIG.

  The fire alarm shown in FIG. 1 is a so-called R-type fire alarm. Therefore, the four terminal devices 20 (1) to 20 (4) output the measurement results, the sensing results, and the like as analog signals, and the fire receiver 10 side performs the fire based on the reception results of these analog signals. Is determined.

Representative examples of the terminal device 20 include the following photoelectric analog sensor and thermal analog sensor.
・ Photoelectric analog sensor In the fire monitoring area, the light emitted from the light emitting part is dimmed under the influence of smoke and is received by the light receiving part, so that the smoke generation can be detected as an analog value. The light receiving unit receives the scattered light obtained by scattering the light emitted from the light emitting unit or the smoke particles by the smoke particles, and thus corresponds to a smoke detector that can detect the generation of smoke as an analog value.
・ Heat analog sensor This is equivalent to a heat sensor that can detect heat as an analog value in a fire monitoring area.

  In addition, as a terminal device that can measure the surrounding situation in the fire monitoring area, a measuring device that measures temperature, pressure, humidity, CO gas, and the like can be used.

Further, the following various sensors can be used as terminal devices.
・ Pressure sensor By connecting a pressure sensor in the piping path of the fire extinguishing system and monitoring the pressure in the piping, it is possible to know the status of sprinkler discharge and the like.

  In addition, by using a repeater for measuring the current of 4 to 20 mA, commercially available sensors that support the current measurement of 4 to 20 mA, which is an industry standard, can be freely connected as the terminal device 20. It becomes possible. Specific examples of the sensors include a gas sensor and a flame sensor.

  In addition, a transmitter that reports that a fire has occurred by pressing a button can be used as the terminal device 20. That is, the terminal device 20 used in the first embodiment transmits, as transmission information, fire-related information used by the fire receiver 10 to determine whether a fire has occurred. Then, the transmission information includes various kinds of sensing result information, measurement result information, operation result information, and the like as described above.

  The detection result by the terminal device 20 may be displayed on the fire receiver not only as a current value obtained in real time, but also as time history data over a certain period as a trend history. By providing such a function of displaying trend data, it is possible to more quickly find the cause of a false alarm.

  For example, if the detection result of the pressure sensor remains as the trend history of the time-series data, it is possible to verify after the fact that the pressure has dropped at once or the pressure has gradually dropped.

  When a gas sensor is used as the terminal device 20, the trend history of the gas concentration obtained as the time-series data of the detection result can be used for subsequent verification. Similarly, when a flame sensor is used as the terminal device 20, the trend history of the flame size obtained as the time-series data of the detection result can be used for subsequent verification.

  Further, when detecting the air pressure by using a differential heat sensor as the terminal device 20, an erroneous alarm may be generated due to a sudden decrease in the air pressure. Even in such a case, the cause of the non-fire alarm of the differential heat sensor can be investigated by referring to the atmospheric pressure trend history obtained as the time series data of the detection result.

  FIG. 2 is a functional block diagram of the fire receiver 10 according to Embodiment 1 of the present invention. Note that the plurality of terminal devices 20 (1) to 20 (4) shown in FIG. 1 are simply illustrated as the plurality of terminal devices 20 in FIG. As the plurality of terminal devices 20, various sensors and measuring devices as described above are conceivable, and can be installed in a desired fire monitoring area.

  The fire receiver 10 shown in FIG. 2 includes a reception unit 11, a storage control unit 12, a fire determination unit 13, a display control unit 14, an operation control unit 15, a storage unit 16, a notification unit 17, a display unit 18, and an operation unit. It comprises 19 mechanisms. Note that the functions of the receiving unit 11, the storage control unit 12, the fire determination unit 13, the display control unit 14, and the operation control unit 15 can be performed collectively by one control unit.

  The receiving unit 11 acquires an analog signal output as transmission information from each terminal device 20 at a predetermined sampling interval, and further performs an analog / digital conversion to generate a digital value. The sampling interval does not need to be a value common to all terminal devices 20, and an appropriate value can be set individually according to a physical quantity to be measured, a fire monitoring area, and the like.

  The storage control unit 12 causes the storage unit 16 to sequentially store the digital values of the detection results by the terminal devices 20 generated by the reception unit 11. At this time, the storage control unit 12 updates the stored data so that the time-series data for a predetermined period of time remains in the storage unit 16. For example, with respect to time-series data in which ten pieces of data are obtained within a predetermined time, the storage control unit 12 performs update processing of the time-series data so that the latest ten pieces of data are stored in the storage unit 16. Will do. Therefore, the transition state of the latest measurement value in the latest predetermined period is stored in the storage unit 16 by performing the update process sequentially.

  The fire determination unit 13 determines whether a fire has occurred based on the latest time-series data or the latest real-time data stored in the storage unit 16. Further, when it is determined that a fire has occurred, the fire determination unit 13 can notify the fire occurrence status via the notification unit 17. Note that the determination processing by the fire determination unit 13 is the same as that of the conventional technique, and a detailed description is omitted.

  The display control unit 14 performs display control for displaying the detection result of the terminal device on the screen of the display unit 18 based on the time-series data that is the detection history of each terminal device stored in the storage unit 16. .

  When the fire determining unit 13 determines that a fire has occurred, the storage control unit 12 continues the update process, and stores data for a predetermined time immediately before the time at which it is determined that a fire has occurred. You can keep it separately. As a result, a trend history having the latest data at the time when it is determined that a fire has occurred is stored in the storage unit 16 separately from the data subjected to normal update processing. As a result, by performing the display control by the display control unit 14, it is possible to easily display the time-series data having the latest data at the time when it is determined that a fire has occurred, and to quickly determine the cause of the false alarm. Becomes possible.

  When the fire determination unit 13 determines that three or more events have occurred in duplicate, the display control unit 14 uses the background color individually set in accordance with the attribute of the event to display three events. The above events can be displayed on one screen. Details of this function will be described later with reference to FIG.

  The operation control unit 15 reads an operation input input by the operator via the operation unit 19, and executes a process according to the operation input. Here, in the fire alarm system as shown in FIG. 1, the operator is required to execute an appropriate operation in accordance with the event that has occurred, promptly notify the fire information, prompt the fire extinguishing work, and the like. .

  The fire receiver 10 according to Embodiment 1 receives, from a plurality of terminal devices, information that determines that a fire has occurred (hereinafter, such information is referred to as an event) in a certain time period in a redundant manner. In this case, a display function is provided to provide the operator with a plurality of duplicated events, and to allow the operator to reliably recognize any of the plurality of events and to suppress the possibility of oversight.

  More specifically, the fire receiver according to Embodiment 1 allows the operator to recognize all of the duplicated events and overlook any of the duplicated events when there are duplicated events in a certain time period. It has a display function that can reduce the risk. Therefore, specific display functions will be described in detail with reference to screen examples.

<Screen example: Screen display when three events are detected in duplicate>
FIG. 3 is a diagram showing an example of a screen displaying a case where three events are detected in duplicate in the first embodiment of the present invention.

  The screen display area in FIG. 3 is roughly divided into an upper information display area 110 and a lower operation display area 120. The information display area 110 shows a display example when the first event 111, the second event 112, and the third event 113 occur in a certain time period. Specifically, FIG. 3 illustrates a case where the following three events overlap.

First event 111: The fire determination unit 13 receives alarm information from one transmitter, determines that the information is one of fire occurrence information, and displays that a fire has occurred.
Second event 112: The fire determination unit 13 receives information from one fire prevention damper that the fire prevention damper has been closed, and receives information that one fire suppression pump has been started, and determines that the fire occurrence information is one of the fire occurrence information. And that the terminal device has been activated.
Third event 113: The fire determination unit 13 receives the detection information from one gas leak detector, determines the information as one of the fire occurrence information, and displays that a gas leak alarm has occurred.

  The operation display area 120 includes a character display area 120A on the left and an illustration display area 120B on the right.

  In the first screen example illustrated in FIG. 3, the display control unit 14 identifies and displays the first event 111, the second event 112, and the third event 113 that have been duplicated in one screen. In particular, the display control unit 14 causes the display unit 18 to identify and display the specific occurrence contents or operation contents together with the occurrence places using characters. As a result, it is possible to realize a fire receiver that can suppress the possibility of an operator overlooking any event when a plurality of events occur in duplicate.

  Note that the display control unit 14 causes the first event 111, the second event 112, and the third event 113 to have different character colors or background colors when displaying a plurality of overlapping events. Can be identified and displayed. In addition to simply displaying multiple events at the same time, by displaying individual events with color identification, even when multiple events occur, it is possible to further suppress the possibility that the operator will overlook any event. Can be.

  It is also possible to specify the character color or the background color in advance according to the type of the event. For example, an event indicating that a fire has occurred, such as a first event, has a background color of red, and an event indicating that a terminal device has actuated, such as a second event, has a background color of blue. An event indicating that a gas leak alarm has occurred, such as three events, may have a background color pattern specified in accordance with the attribute of each event, such as setting the background color to yellow. As a result, even when a plurality of events occur at the same time, it is possible to prevent the operator from overlooking any of the events, and the operator can easily identify the attribute of the event based on the background color pattern. It is possible to do.

Next, a method of incorporating the function of the emergency telephone panel 300 into the fire receiver 10 will be described.
FIG. 4 is an overall configuration diagram of a conventional fire alarm system that includes an emergency telephone board 300 and a conventional fire receiver 200 and performs an emergency telephone call. As shown in FIG. 4, in the conventional fire alarm system, in order to make a call with an emergency telephone handset 400a provided in, for example, a fire hydrant BOX 400 corresponding to an external device, an emergency telephone board operation provided with an emergency telephone 310a is performed. The emergency telephone panel 300 having the unit 310 has to be installed separately from the fire receiver 200. Therefore, the provision of the emergency telephone panel 300 has caused an increase in cost and an increase in installation space.

  Therefore, the first embodiment implements a configuration in which a call function using an emergency telephone by the emergency telephone board 300 is incorporated into the fire receiver 10 shown in FIGS. 1 and 2, and will be described in detail below. .

  FIG. 5 is a first explanatory diagram showing a configuration in which a call function using an emergency telephone is added to fire receiver 10 according to Embodiment 1 of the present invention. As shown in FIG. 5, the fire receiver 10 is newly provided with an emergency telephone base unit 10a. Furthermore, the fire receiver 10 and the fire hydrant BOX 400 are used for emergency calls in order to enable voice communication between the emergency telephone master unit 10a on the fire receiver 10 side and the emergency telephone handset 400a on the fire hydrant BOX 400 side. They are interconnected via a repeater 50.

  FIG. 6 is a second explanatory diagram showing a configuration in which a call function using an emergency telephone is added to fire receiver 10 according to Embodiment 1 of the present invention. The operation of the fire receiver 10 when an incoming call is received from the emergency telephone handset 400a will be described in detail with reference to FIG.

  The transmission signal from the emergency telephone handset 400a is received by the communication unit 11a in the fire receiver 10 via the emergency telephone repeater 50. The communication unit 11a will be described later with reference to FIG. Then, when the communication unit 11a receives the transmission signal, it notifies the display control unit 14 in the fire receiver 10 as incoming information from the emergency telephone handset 400a. As a result, the display control unit 14 performs a display as shown on the left side of FIG. 6 in the screen display area of the fire receiver 10.

  Specifically, incoming information indicating that there is an incoming call from the emergency telephone handset 400a is displayed in the upper information display area 110, and a call with the emergency phone handset 400a is displayed in the lower operation display area 120. , Specific operation guidance of the emergency telephone master device 10a is displayed.

  Accordingly, the operator can easily make a voice call with the emergency telephone handset 400a via the emergency telephone repeater 50 using the emergency telephone base unit 10a provided in the fire receiver 10. it can. In this way, it is possible to realize the fire receiver 10 which also has the function of the emergency telephone board 300 and can suppress the increase in cost and installation space.

  FIG. 7 is a functional block diagram of a fire receiver 10 having a telephone call function using an emergency telephone according to Embodiment 1 of the present invention. As compared with the functional block diagram shown in FIG. 2, the fire receiver 10 shown in FIG. 7 includes a communication unit 11 a instead of the reception unit 11. Here, the communication unit 11a has a receiving function of receiving fire-related information from each of the plurality of terminal devices 20, and a communication control function of realizing a call between the emergency telephone base unit 10a and the emergency telephone slave unit 400a. It has both.

  The fire receiver 10 is also configured so that a maintenance telephone used by a worker during construction and maintenance can be connected. As for the maintenance telephone, when the telephone plug of the receiver for the maintenance telephone is inserted into a telephone jack provided on the site side such as a transmitter, the fire receiver 10 outputs a ringing tone. Here, when the operator inserts the telephone plug of the receiver for the maintenance telephone into the telephone jack provided in the fire receiver 10, it is possible to talk with the site. Therefore, when incorporating the function of the emergency telephone board 300 into the fire receiver 10, it is important to distinguish between a ringing tone when a maintenance telephone arrives and a ringing tone when an emergency telephone arrives.

  Further, it is conceivable that fire occurrence information from the terminal device 20 or the like arrives at the fire receiver 10 in addition to the incoming call from the emergency telephone handset 400a. Therefore, it is also important how to identify and report a plurality of pieces of information that are repeatedly received by the fire receiver 10. Therefore, a notification process when information is duplicated will be described in detail below based on a specific example.

<Specific example 1: Identification of incoming call between emergency phone and maintenance phone>
The fire receiver 10 can distinguish between the incoming call from the emergency telephone handset 400a and the incoming call from the maintenance phone as different sounds from the notifying unit 17 as different sounds. For example, when an incoming call is received from the maintenance phone, an alarm sound such as “Plurul” is output, and when an incoming call is received from the emergency telephone handset 400a, an alarm sound such as “Pirillo” is output. .

<Specific Example 2: When Three or More Events Occur Simultaneously, Notification Processing is Performed Considering Priority>
When three or more events occur at the same time, a notification using an alarm sound + a notification using a voice is performed for the top two events in accordance with a predetermined priority, and a voice is used for other events. It is conceivable that only the notification using is performed. By performing such a notification process, it is possible to avoid a state in which three or more notifications using the alarm sound are duplicated, and the notification using the sound and the display of the character information are performed for all events. It is possible to do.

For example, consider a case where the following three events 1 to 3 are duplicated in the descending order of priority.
Event 1: Fire confirmed
Notification using alarm sound "P"
Notification using sound "A fire has occurred. Check the site."
Event 2: Emergency call
Notification using alarm sound "Pirillo"
Notification using voice "An emergency call has arrived."
Event 3: Gas leak
Notification using alarm sound "pipipipi"
Information using sound "Gas leak occurred. Check the site."

  When these three events 1 to 3 are duplicated, regarding the notification using the alarm sound, “Pi” of event 1 and “Pirorilo” of event 2 are executed, and “pipipipi” of event 3 is executed. The notification using the alarm sound is omitted.

  On the other hand, in the notification using sound, all of event 1 to event 3 are performed, and character information is displayed in the information display area 110. In addition, the notification using the alarm sound of the event 1 and the event 2 is stopped, so that the notification regarding the event 3 using the alarm sound “pipipipi” can be executed. In this case, "P", "A fire has occurred. Check the site.", "Pirillo", "An emergency call has been received.", "A gas leak has occurred. Check the site. Please. ”, The alarm sound and the sound are repeated in this order.

<Specific example 3: About events of lower importance, such as the operation of terminal devices or the operation of fire prevention equipment>
Consider a case where the following events 4 to 6 occur in addition to the events 1 to 3 shown in the specific example 2.
Event 4: Fire door activation
Notification using alarm sound "Boo"
Notification using sound "The fire door has been activated. Please check the site."
Event 5: Fire protection shutter operation
Notification using alarm sound "Boo"
Notification using sound "The fire shutter has been activated. Check the site."
Event 6: Terminal device activation
Notification using alarm sound "Boo"
Notification using sound "Terminal device has been activated. Check the site."

  Assume that these three events 4 to 6 are determined in advance as events having lower priority and lower importance than events 1 to 3. In this case, regarding the events 4 to 6, neither the notification using the alarm sound nor the notification using the voice can be executed.

  In this case as well, "P", "A fire has occurred. Check the site.", "Pirillo", "An emergency call has been received.", "A gas leak has occurred. Check the site. Please repeat the alarm sound and voice in this order. At this time, the event 4 to the event 6 may be displayed in the information display area 110 together with the event 1 to the event 3, or may be displayed by an operator performing a screen feed operation.

  In addition, by stopping the notification using the alarm sound of the event 1 to the event 3, it is possible to execute the notification regarding the event 4 to the event 6 using the alarm sound of “boo”.

  By performing the notification processing as shown in the specific examples 1 to 3 described above, the fire receiver 10 having the function of the emergency telephone panel 300 identifies the incoming of the emergency telephone and the maintenance telephone, and has the priority. According to the order, the fire-related information and the incoming call information that have occurred repeatedly can be appropriately identified and notified.

  In addition, the number of events to be notified using both the alarm sound and the voice preset for each event is a predetermined number of events from the top according to a predetermined priority, and a desired number according to the usage environment and the like. Can be set.

  As described above, according to the first embodiment, it is possible to realize a fire receiver that also has the function of an emergency telephone board, and that can suppress an increase in cost and an increase in installation space. Further, by performing the notification processing in accordance with the priority order, it is possible to realize the incoming call identification of the emergency telephone and the maintenance telephone and the appropriate notification of the fire-related information generated repeatedly.

  Reference Signs List 10 fire receiver, 10a emergency telephone base unit, 11a communication unit, 12 storage control unit, 13 fire determination unit, 14 display control unit, 15 operation control unit, 16 storage unit, 17 notification unit, 18 display unit, 19 operation unit , 20 terminal equipment, 30 repeaters, 50 emergency telephone repeaters, 400a emergency telephone handset.
