JP7770271B2 - Fire alarm system - Google Patents

Description

This disclosure relates to a fire alarm system equipped with a fire receiver and multiple fire detectors, and in particular to a fire alarm system suitable for testing the operation of fire detectors.

During regular inspections of automatic fire alarm systems and fire drills, performance is confirmed by testing the operation of fire detectors using smoke and heat testing equipment. A system has been proposed that allows for more efficient testing of such fire detectors (see, for example, Patent Document 1).

Patent Document 1 discloses a system in which an inspector uses a mobile terminal to select a fire detector for an operation test, and the results of the operation test conducted using a test jig are sent to the mobile terminal. As a result, Patent Document 1 eliminates the need for an inspector to be present on the server and receiver side, allowing detector alarm testing to be carried out efficiently with just one inspector conducting the operation test using the test jig.

Japanese Patent Application Laid-Open No. 2018-112951

However, the conventional techniques have the following problems.
The system disclosed in Patent Document 1 requires a configuration in which fire detectors, receivers, and a server are connected via a network. Furthermore, an inspector must use a mobile terminal with dedicated software installed to select the fire detectors to be tested, conduct the test, and receive the test report results from the server.

Thus, although operation testing can be performed by a single inspector, the system configuration is complex.

Furthermore, in Patent Document 1, when actually conducting an activation test using a test jig, it is not possible to confirm whether the fire detector selected using a mobile terminal matches the fire detector that should actually be tested. As a result, there is a risk that an activation test will be conducted on a fire detector other than the one selected, which may not necessarily improve work efficiency.

This disclosure has been made to solve the above-mentioned problems, and aims to provide a fire alarm system that is configured with a fire receiver and multiple fire detectors and that can efficiently conduct operation tests on selected fire detectors.

Hereinafter, preferred embodiments of the fire alarm system of the present disclosure will be described with reference to the drawings.
The fire alarm system according to the present disclosure has a technical feature in that, for a fire detector selected as a target for an operation test, an indicator provided on the detector body displays an identification mark indicating that the detector is a target for an operation test. As a result, an inspector can easily visually confirm the fire detector that is the target for the operation test based on the identification marking and then perform the operation test.

Embodiment 1.
First, the overall system will be described.
1 is a diagram illustrating the overall configuration of a fire alarm system including a fire receiver and a plurality of fire detectors according to a first embodiment of the present disclosure. The fire receiver 10 is connected to an addressable transmitter 20, fire detectors 31 and 32, a detector repeater 40, and a smoke control repeater 50 via a signal line SG.

Multiple fire detectors are connected to the detector repeater 40. Figure 1 shows four fire detectors 41-44. Furthermore, a fire door 51, a smoke exhaust fan 52, a shutter 53, and a siding wall 54 are connected to the smoke prevention and exhaust control repeater 50.

Here, fire detectors 31, 32, and fire detectors 41-44 correspond to multiple fire detectors that detect the occurrence of a fire in each of the pre-set fire monitoring areas. A detector group is made up of multiple fire detectors.

Furthermore, the fire door 51, smoke exhaust fan 52, shutter 53, and drop wall 54 correspond to multiple terminal equipment that operate in conjunction with the detection results of multiple fire detectors and function to prevent the spread of fire, smoke, etc. The multiple terminal equipment constitute a terminal equipment group.

Each of the multiple fire detectors is assigned address information in advance to identify the individual fire detector. Each of the multiple fire detectors can then transmit fire-related information to the fire receiver 10, including the address information assigned to that detector. Meanwhile, the fire receiver 10 can transmit the necessary information to the desired fire detector by adding address information when transmitting the information.

In addition, each of the multiple terminal devices is assigned address information in advance to identify the individual terminal device. Therefore, the fire control device 10 can send a command to operate the desired terminal device by adding address information and transmitting the information.

With this configuration, the fire receiver 10 collects fire-related information from multiple fire detectors and addressable transmitters 20 installed in various predetermined fire monitoring areas. Based on the collected fire-related information, the fire receiver 10 can then issue a fire alarm and activate a group of terminal equipment.

It is predefined that each piece of terminal equipment included in the group of terminal equipment should operate in conjunction with the detection results of a fire detector. For example, by pre-setting the correspondence between the interlocking operations of multiple fire detectors and multiple terminal equipment as an interlocking table, the fire receiver 10 can identify the appropriate terminal equipment from the interlocking table based on the detection results of each of the multiple fire detectors and perform interlocking operations.

In addition, although not shown in the figure, the fire receiver 10 can output an alarm signal based on the collected fire-related information, activate fire extinguishing equipment to begin fire-fighting operations, issue a fire alarm or provide evacuation guidance via an emergency broadcast device, and transmit fire-related information to a higher-level device via a network.

Next, we will explain the technical features of the fire alarm system according to this embodiment 1. The fire alarm system according to this embodiment 1 is technically characterized in that the fire receiver has a mode setting function and a first selection function, and each of the multiple fire detectors has an identification display function. Each function will now be explained in detail.

<About the mode setting function>
The fire control panel 10, which centrally controls the detectors and terminal equipment, has a mode setting function that controls switching between a fire monitoring mode for monitoring fires and an operation test mode for testing the operation of multiple fire detectors. This mode setting function can be realized, for example, by a touch panel provided on the fire control panel 10.

When using a touch panel, the inspector will switch from fire monitoring mode to operation test mode by operating the touch panel on the fire receiver 10 before conducting the fire detector operation test.

<Regarding the first selection function>
When performing an operation test in the operation test mode, the fire receiver 10 is capable of selecting one or more fire detectors from a plurality of fire detectors to be the subject of the operation test, and further has a first selection function of transmitting an operation test subject signal to the one or more fire detectors selected as the subject of the operation test, indicating that they are the subject of the operation test.

Figure 2 shows an example screen displayed on a touch panel in embodiment 1 of the present disclosure, allowing a user to select one or more fire detectors to be tested for operation from among multiple fire detectors.

Figure 2 illustrates an example in which six fire detectors 31, 32, 41-44 are displayed as corresponding windows W11-W16, corresponding to the configuration in Figure 1. Furthermore, a "Start Unit Test" button for starting a unit test on the fire detector selected for the operation test is displayed as window W31.

Therefore, inspectors can select the desired fire detector to be tested for operation by touching the touch panel, and can begin the individual test after selection.

Figure 3 shows an example screen displayed after one fire detector to be tested for operation has been selected from among multiple fire detectors in embodiment 1 of the present disclosure. Figure 3 illustrates a state in which "fire detector 41" is selected from among a group of detectors, causing "fire detector 41" to be highlighted. If "Start unit test" is pressed after such a selection operation, the fire receiver 10 transmits an operation test target signal including the address information of fire detector 41 via signal line SG.

<About the identification display function>
Each of the plurality of fire detectors has an identification display function that, when it receives an operation test target signal from the fire receiver 10, displays an identification display indicating that the fire detector is a target for operation test.

For example, when fire detector 41 transmits an operation test target signal containing its own address information, it uses a display attached to the detector body to display an identification indication that the detector is a target for operation test using a predetermined lighting pattern, color, etc. Therefore, inspectors at the fire detector installation site can easily visually identify which fire detectors are targeting operation test. The display may be a fire confirmation light that lights up when the fire detector detects a fire.

When the operation test mode is set, the fire receiver 10 only allows operation tests on the fire detector itself, and can prohibit linked operation that activates related terminal equipment based on the detection results. In other words, when the fire receiver 10 receives a detection result from a fire detector that transmitted an operation test target signal, it will perform control not to perform linked operation. It will also perform control not to output an alarm signal to fire extinguishing equipment or emergency broadcast devices.

As described above, according to embodiment 1, fire detectors selected for operation testing can be marked with an identification mark indicating that they are being tested. As a result, inspectors can easily visually identify fire detectors that are being tested based on the identification markings and then conduct the test, improving work efficiency.

Note that Figure 3 illustrates the case where one fire detector is selected as the target for an operation test, but it is also possible to select two or more fire detectors as the target for an operation test.

Embodiment 2.
In the first embodiment, a method for improving work efficiency when an operation test is performed on a single fire detector was described. In contrast, in the second embodiment, a method for improving work efficiency when an interlocking operation test is performed in which terminal equipment is interlocked based on the detection result of the fire detector is described, while utilizing the identification display function.

The fire alarm system according to the second embodiment is technically characterized in that the fire alarm receiver further has a first extraction function, a second selection function, and a first interlocking operation test function, and also has a mode setting function that allows switching between a standalone test mode and an interlocking test mode. Each function will now be described in detail.

<Improvements to the mode setting function>
In the second embodiment, an interlocking operation test can be performed to interlock terminal equipment based on the detection result of the fire detector. Therefore, when the operation test mode is selected in the mode setting function, the fire control panel 10 according to the second embodiment further performs setting switching control between a unit test mode in which an operation test of the fire detector alone is performed, and an interlocking test mode in which an operation test involving interlocking operation of the fire detector and terminal equipment is performed.

Therefore, before conducting a fire detector operation test, an inspector can easily switch the settings by operating the touch panel on the fire receiver 10 to either conduct an operation test of the fire detector alone or an operation test involving linked operation of the fire detector and terminal equipment.

<Regarding the first extraction function>
When the interlocking test mode is selected, the fire receiver 10 allows selection of one terminal equipment to be the subject of the interlocking test from among a plurality of terminal equipment that operate in conjunction with the respective detection results of a plurality of fire detectors, and has a first extraction function that extracts the fire detector that is the source of the interlocking test for the one terminal equipment selected as the subject of the interlocking test.

<Regarding the second selection function>
When performing an operation test involving the operation of a fire detector linked to a terminal device during the linkage test mode, the fire receiver 10 has a second selection function that enables selection of one fire detector to be the subject of the operation test from among the fire detectors that are the source of the linkage extracted by the extraction function, and transmits an operation test subject signal to the one fire detector selected as the subject of the operation test.

Figure 4 shows an example screen displayed on a touch panel when the interlocking test mode is selected in embodiment 2 of the present disclosure. Corresponding to the configuration of Figure 1, Figure 4 illustrates an example in which six fire detectors 31, 32, 41-44 are displayed as corresponding windows W11-W16, and four terminal equipment units, fire door 51, smoke exhaust fan 52, shutter 53, and siding wall 54, are displayed as corresponding windows W21-W24.

Furthermore, in Figure 4, a "Start Interlocking Test" button is displayed as window W32 to start an interlocking test between the terminal equipment selected as the interlocking test target and the fire detector selected as the interlocking source, that is, the operation test target.

Note that windows W11 to W16 each have sub-windows W111 to W116, and windows W21 to W24 each have sub-windows W121 to W124. The role of the sub-windows will be explained later using Figures 5A and 5B.

By touching the screen on the touch panel shown in Figure 4, the inspector can select the desired fire detectors to be tested for operation and the terminal equipment to be tested for interlocking, and can then start the interlocking test after making the selection.

Figure 5A shows an example screen after one terminal device is selected from multiple terminal devices to be the target of an interlocking test in embodiment 2 of the present disclosure. In embodiment 2 of the present disclosure, when interlocking between a fire detector and terminal device is performed, the terminal device to be interlocked is first selected.

In Figure 5A, when "Fire Door 51" is selected from the group of terminal equipment, "Fire Door 51" is displayed in inverted, and the state in which the link sources of "Fire Door 51" are "Fire Detector 31" and "Fire Detector 41" is illustrated.

Specifically, the fire receiver 10 refers to an interlocking table in which the correspondence between the interlocking operations of multiple fire detectors and multiple terminal devices is preset, and if it determines that the interlocking sources of "fire door 51" are "fire detector 31" and "fire detector 41," it identifiably displays sub-window W111 corresponding to "fire detector 31" and sub-window W113 corresponding to "fire detector 41."

Therefore, inspectors can easily determine which fire detector is the interlocking source for the selected "fire door 51" by visually checking the identification markings on the touch panel, without having to check the interlocking table.

Figure 5B is a diagram showing an example screen in which one terminal device to be the subject of an interlocking test has been selected, and then one fire detector to be the interlocking source has been selected, in embodiment 2 of the present disclosure. Specifically, Figure 5B shows an example screen in which "fire door 51" has been selected as one terminal device to be the subject of an interlocking test, and then "fire detector 41" has been selected from "fire detector 31" and "fire detector 41" to be the interlocking source, causing "fire detector 41" to be highlighted.

Specifically, the inspector identifies "Fire Detector 31," whose sub-window W111 is illuminated, and "Fire Detector 41," whose sub-window W113 is illuminated, as the fire detectors that will be interlocked with "Fire Door 51." The inspector can then select "Fire Detector 41" as the desired target for the operation test, and after selection, can start the interlock test by pressing the "Start Interlock Test" button.

When this series of selection and start operations is performed, the fire receiver 10 transmits an operation test target signal containing the address information of the fire detector 41 via the signal line SG. Meanwhile, when the fire detector 41 receives the operation test target signal from the fire receiver 10, it displays an identification display on the display provided on the detector body to indicate that the detector is a target for operation test, and executes the identification display function.

<Regarding the first interlocking operation test function>
During the interlocking test mode, the fire receiver 10 has an interlocking operation test function that receives detection results from the fire detector 41 that has received the operation test target signal, and outputs an interlocking operation command to perform an interlocking operation on the fire door 51, which is one of the terminal equipment that is the target of the interlocking test.

As a result, the fire control receiver 10 can perform an operation test that involves linking one fire detector to be tested and one piece of terminal equipment to be tested, based on the inspector's selection. In other words, even if there is terminal equipment other than the fire door 51 that links with the fire detector 41, the fire control receiver 10 can link only the fire door 51 and perform a one-to-one linkage test between the fire detector 41 and the fire door 51.

As described above, according to the second embodiment, fire detectors selected for operation testing can be identified as being subject to operation testing, just as in the first embodiment.

Furthermore, according to embodiment 2, an interlocking test between the terminal equipment selected as the interlocking test target and the fire detector selected as the interlocking source operation test target can be easily performed by selecting and starting using the touch panel, without having to check the interlocking table.

Embodiment 3.
In the previous embodiment 2, a method for improving work efficiency when an operation test is performed on a single fire detector was described. In contrast, in this embodiment 3, a method for improving work efficiency when an interlocking operation test is performed in which terminal equipment is interlocked based on the detection result of a fire detector, utilizing the identification display function, will be described, which is different from the method in the previous embodiment 2.

The fire alarm system according to the third embodiment is technically characterized in that the fire alarm receiver further has a second extraction function, a third selection function, and a second interlocking operation test function, and also has a mode setting function that allows switching between a standalone test mode and an interlocking test mode. Each function will now be described in detail.

In the previous second embodiment, when conducting an interlocking test, the terminal device was selected, and then the fire detector that will be the interlocking source was selected. In contrast, in this third embodiment, when conducting an interlocking test, the fire detector is selected, and then the terminal device that will be the interlocking destination is selected, which is a different selection order.

<Improvements to the mode setting function>
In this embodiment 3, similar to the previous embodiment 2, it is possible to perform an interlocking operation test that interlocks terminal equipment based on the detection result of a fire detector. Therefore, similar to the previous embodiment 2, when the operation test mode is selected in the mode setting function, the fire control panel 10 according to this embodiment 3 further performs setting switching control between a unit test mode that performs an operation test of the fire detector alone and an interlocking test mode that performs an operation test involving interlocking operation between the fire detector and terminal equipment.

Therefore, before conducting a fire detector operation test, an inspector can easily switch the settings by operating the touch panel on the fire receiver 10 to either conduct an operation test of the fire detector alone or an operation test involving linked operation of the fire detector and terminal equipment.

<Regarding the second extraction function>
When the interlocking test mode is selected, the fire receiver 10 allows the user to select one fire detector from among multiple fire detectors to be the subject of an operation test as the source of the interlocking, and has a second extraction function that extracts the terminal equipment to be interlocked with the one fire detector selected as the subject of the operation test.

<About the third selection function>
When performing an operation test involving the operation of a fire detector and a terminal device during the interlocking test mode, the fire receiver 10 has a third selection function that allows selection of one terminal device to be the subject of the interlocking test from the terminal devices to be linked that are extracted by the extraction function, and transmits an operation test subject signal to the one fire detector selected as the subject of the operation test.

By performing touch inputs on the touch panel screen shown in Figure 4, which was previously described in the second embodiment, the inspector can select the desired fire detectors to be tested for operation and the terminal equipment to be tested for interlocking, and can then start the interlocking test after making the selections.

Figure 6A shows an example screen after one fire detector to be tested as the source of interlocking has been selected from among multiple fire detectors in embodiment 3 of the present disclosure. In embodiment 3, when performing interlocking between a fire detector and terminal equipment, the fire detector to be the source of interlocking is first selected.

In Figure 6A, when "Fire detector 41" is selected from the group of fire detectors, "Fire detector 41" is displayed in inverted, and the state in which "Fire detector 41" is linked to "Fire door 51" and "Shutter 53" is illustrated.

Specifically, the fire receiver 10 refers to an interlocking table in which the correspondence between the interlocking operations of multiple fire detectors and multiple terminal devices is preset, and if it determines that the interlocking destinations of "fire detector 41" are "fire door 51" and "shutter 53," it distinguishably displays sub-window W121 corresponding to "fire door 51" and sub-window W123 corresponding to "shutter 53."

Therefore, inspectors can easily determine which terminal equipment the selected "fire detector 41" is linked to by visually checking the identification display on the touch panel, without having to check the linkage table.

Figure 6B is a diagram showing an example screen in which, after a fire detector to be tested for operation has been selected, one terminal device is selected from among the linked terminal devices in embodiment 3 of the present disclosure. Specifically, Figure 6B illustrates an example screen in which, after "fire detector 41" has been selected as the fire detector to be tested for operation, "shutter 53" is selected from among the linked fire doors "fire door 51" and "shutter 53," causing "shutter 53" to be highlighted.

Specifically, the inspector identifies that "fire door 51," whose sub-window W121 is lit, and "shutter 53," whose sub-window W123 is lit, are the terminal equipment to be linked with "fire detector 41." The inspector can then select "shutter 53" as the desired interlocking test target, and after selection, can start the interlocking test by pressing the "Start interlocking test" button.

When this series of selection and start operations is performed, the fire receiver 10 transmits an operation test target signal containing the address information of the fire detector 41 via the signal line SG. Meanwhile, when the fire detector 41 receives the operation test target signal from the fire receiver 10, it displays an identification display on the display provided on the detector body to indicate that the detector is a target for operation test, and executes the identification display function.

<Regarding the second interlocking operation test function>
During the interlocking test mode, the fire receiver 10 has an interlocking operation test function that receives detection results from the fire detector 41 that has received the operation test target signal, and outputs an interlocking operation command to perform an interlocking operation on the shutter 53, which is one of the terminal equipment that is the target of the interlocking test.

As a result, the fire control device 10 can perform an operation test that involves linking one fire detector to be tested and one terminal device to be tested, based on the inspector's selection. In other words, even if there is terminal device other than the shutter 53 that links with the fire detector 41, the fire control device 10 can link only the shutter 53 and perform a one-to-one linkage test between the fire detector 41 and the shutter 53.

As described above, according to embodiment 3, fire detectors selected for operation testing can be identified as being subject to operation testing, as in embodiments 1 and 2 above.

Furthermore, according to this third embodiment, an interlocking test between a fire detector selected as the target for an operation test and a terminal device selected as the target for the interlocking test can be easily performed by selecting and starting the test using a touch panel, without having to check the interlocking table.

Note that the screen examples shown in Figures 2 to 6B in the above-described first to third embodiments are merely examples, and other screens may be used as long as they can realize the functions of the fire alarm system of the present disclosure.

Furthermore, the fire receiver can transmit different signals for the operation test target signal in the individual test mode and the operation test target signal in the linked test mode, so that they can be distinguished on the fire detector side. In this case, the fire detector can use different lighting patterns, lighting colors, etc. for the identification marking indicating that the fire detector is a target for operation test in the individual test mode and the identification marking indicating that the fire detector is a target for operation test in the linked test mode.

As a result, inspectors can easily visually confirm the fire detectors that are the subject of an operation test based on the identification display results, and can easily visually confirm whether an interlocking test will be conducted in which the terminal equipment operates in conjunction with the fire detector, improving the work efficiency of the interlocking test.

Furthermore, in the above-mentioned second and third embodiments, we have described the case where a one-to-one interlocking test is performed between a fire detector and terminal equipment, but it is also possible to perform an interlocking test in a one-to-N (N is an integer of 2 or greater) relationship where multiple terminal equipment are interlocked with one fire detector.

Furthermore, in the above-mentioned embodiment 1, we have described a case where interlocking control and signal transmission output are not performed when the operation test mode is set. However, these controls can be set manually, and when the operation test mode is selected and Figure 2 or Figure 3 is displayed, it is also possible to provide new windows with a "All interlocking operation cutoff" button for prohibiting all interlocking operations at once, a "All signal transmission signal cutoff" button for prohibiting all signal transmission output at once, and a "All cutoff" button for prohibiting both interlocking operation and signal transmission output at once.

Each time the inspector touches the "All Interlocking Operation Cutoff" button, "All Announcement Signal Cutoff" button, or "All Cutoff" button, the "All Interlocking Operation Cutoff," "All Announcement Signal Cutoff," and "All Cutoff" lights alternate between on and off. This allows you to control whether or not interlocking operations or Announcement signal output will occur.

Furthermore, in the above-mentioned embodiments 2 and 3, a one-to-one interlocking test is performed between a fire detector and terminal equipment. However, when the interlocking mode is selected and Figures 4 to 6B are displayed, it is also possible to provide a new window with a "Bulk Interlocking Operation Block" button to prohibit all interlocking operations at once.

Each time the inspector touches the "Interlocking Operation All Shutdown" button, the "Interlocking Operation All Shutdown" indicator alternates between on and off. Even when interlocking mode is selected, the inspector can disable all interlocking operations at once by turning on the "Interlocking Operation All Shutdown" indicator, allowing them to test the operation of only the selected fire detectors, just like the "unit test mode" described in the first embodiment.

In addition, although not shown in the screen examples of Figures 2 to 6B in Embodiments 1 to 3, a return button for returning from operation test mode to fire monitoring mode can be provided on the screen. By touching this return button, the inspector can return from operation test mode to fire monitoring mode.

Furthermore, when the return button is selected to return to fire monitoring mode, the fire receiver 10 can reset all of the states selected in embodiments 1 to 3. In other words, by automatically performing this reset process when returning to fire monitoring mode, the fire receiver 10 can return to the initial state in accordance with the interlocking table during fire monitoring.

As a result, even if the system returns to fire monitoring mode without switching the "all-linked operation cutoff," "all-transmission signal cutoff," or "all-linked cutoff" to the off state, it is possible to reliably prevent human error, such as cutting off the all-linked operation when a fire is detected in fire monitoring mode.

Furthermore, in the first to third embodiments, we have described the case where various functions are realized using a touch panel provided on the fire control receiver 10, but this configuration is not limited to this. The same effect can be achieved even if a configuration is adopted in which the various functions realized on the touch panel in the first to third embodiments are implemented on an integrated control panel or external device that can communicate with the fire control receiver 10. Here, external devices include terminal devices such as mobile devices carried by inspectors.

Furthermore, in embodiments 1 to 3, fire detectors selected for operation testing are identified by a display on the detector body to indicate that they are the subject of an operation test, but it is conceivable that an inspector may perform an operation test on a fire detector that does not have an identification display.

Even when such an erroneous operation occurs, if the fire receiver 10 according to the present disclosure receives a detection result from a fire detector that has not been selected for an operation test while the operation test mode is selected, it can determine that an erroneous operation has occurred and control the receiver so that the interlocking operation according to the interlocking table is not performed.

Furthermore, if the fire receiver 10 determines that an erroneous operation has occurred, it can use a display provided on the main body of the fire detector in which the erroneous operation occurred to display an identification display indicating that the fire detector has not been selected for an operation test.

As a result, even if an inspector mistakenly performs an operation test on a fire detector that is not the subject of the operation test, linked operation can be reliably prevented and the inspector can be quickly and visually notified that an incorrect operation has occurred.
