Description

[Technical Field]

[0001] The present disclosure relates to an equipment control panel that detects and displays a fire outbreak situation based on information from multiple terminal devices, and in particular to an equipment control panel that is suitable for verifying an abnormality history. [Background technology]

[0002] Conventionally, fire receivers used in fire alarm systems that monitor smoke generation, temperature rise, and other factors that can cause fires have been installed in disaster prevention centers, control rooms, etc. Fire receivers determine whether a fire has occurred by receiving signals from one or more terminal devices installed in each fire monitoring area.

[0003] In this way, the fire receiver performs centralized monitoring and control of various terminal devices included in the fire alarm system. Note that such centralized monitoring and control can also be performed by other equipment, such as a general control panel. Therefore, in this disclosure, facility equipment such as the fire receiver and general control panel that perform centralized monitoring and control of various terminal devices will be collectively referred to as an equipment control panel.

[0004] As such an equipment control panel, there is a conventional technology that monitors by measuring the current of terminal equipment installed inside the tunnel and displays disaster occurrence information by receiving a disaster occurrence signal (see, for example, Patent Document 1).

[0005] More specifically, the equipment according to Patent Document 1 stores an abnormality history in a memory unit that associates the measurement results with the measurement date and time and information on whether or not an abnormality occurred, and displays the abnormality history on a touch panel in order of the most recent abnormality occurrence date and time.

[0006] In addition, in the facility disclosed in Patent Document 1, the degree of abnormality is divided into three levels: mild, medium, and severe, and the abnormalities are sorted based on the information on the degree of abnormality, and the abnormality history can be displayed on the screen in order of the most severe abnormality. Furthermore, in the facility disclosed in Patent Document 1, the background of the abnormality history is color-coded according to the degree of abnormality, making it possible to intuitively grasp the occurrence of an abnormality in terminal equipment and improving work efficiency during maintenance. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Publication No. 2019-79366 Summary of the Invention [Problem to be solved by the invention]

[0008] However, the conventional techniques have the following problems. For example, even if a terminal device is installed in accordance with the law, if the environment exceeds the assumptions of the law, it may misidentify a fire even when it is not a fire at various frequencies or intervals, resulting in false alarms. In such cases, there is a demand for the ability to verify the detection results of one or more desired terminal devices on a single screen.

[0009] In particular, for terminal devices that frequently emit false alarms, it is important to identify the cause of the false alarm. A false alarm here refers to a situation in which the terminal device determines that a fire has occurred when there is no fire. More specifically, this could be due to an abnormality in the device or an event caused by the installation location (steam or dust for a smoke detector, a sudden change in temperature for a heat detector, etc.).

[0010] In order to identify the cause of false alarms, it may be necessary to narrow down to a specific terminal device that frequently outputs an activation signal and verify the activation signal output history of the terminal device. However, the prior art disclosed in Patent Document 1 does not have a display function that narrows down to a specific terminal device.

[0011] In the case of fire alarm systems in which terminal equipment is installed in an environment that exceeds the assumptions of the installation standards, the conventional technology described in Patent Document 1 simply displays the abnormality history by sorting it according to the order in which the abnormalities occurred and the severity of the abnormality, and also displays the abnormality using a background color that corresponds to the severity of the abnormality.

[0012] Therefore, in Patent Document 1, it is necessary to verify a specific terminal device while viewing multiple screens, and it is necessary to repeatedly switch between screens in order to quickly identify the cause of the false alarm.

[0013] The present disclosure has been made to solve the above-mentioned problems, and aims to provide an equipment control panel suitable for verifying an abnormality history using a specific terminal device. [Means for solving the problem]

[0014] The device operation panel according to the present disclosure includes a receiving unit that receives an actuation signal output from each of a plurality of terminal devices in response to a state change; a storage control unit that stores in a storage unit reception history information generated by associating each actuation signal received by the receiving unit with a reception time; a display control unit that displays on a display unit the reception history information stored in the storage unit; and a display condition input unit that sets display conditions for selectively displaying a desired period and a desired terminal device for the reception history information stored in the storage unit, and the display control unit receives information regarding the desired period and the desired terminal device as display conditions set by the display condition input unit, and has an identification display function that extracts and displays reception history information related to the desired terminal device within the desired period when displaying the reception history information. The display control unit identifies the same terminal device that has output an activation signal a predetermined number of times or more within a desired period based on the results of the reception history information generated by the storage control unit, and displays the identified same terminal device in a color on the display unit. It is something. In addition, the device control panel of the present disclosure includes a receiving unit that receives activation signals output from each of a plurality of terminal devices in response to a change in state; a memory control unit that stores in a memory unit reception history information generated by associating each activation signal received by the receiving unit with the time of reception; a display control unit that displays the reception history information stored in the memory unit on a display unit; and a display condition input unit that sets display conditions for selectively displaying a desired period and a desired terminal device for the reception history information stored in the memory unit.The display control unit receives information related to the desired period and the desired terminal device as display conditions set in the display condition input unit, and has an identification display function that, when displaying the reception history information, extracts and displays reception history information related to the desired terminal device within the desired period.The display control unit is connectable to an external display unit that has display capabilities that enable it to display on a single screen a number of expanded display data items that exceeds the number of screen display data items of reception history information that can be displayed on a single screen on the display unit.The display control unit edits the reception history information consisting of the number of expanded display data items to match the display capabilities of the external display unit, and displays the edited result on the external display unit. In addition, the device control panel of the present disclosure includes a receiving unit that receives activation signals output from each of a plurality of terminal devices in response to a change in state; a memory control unit that stores in a memory unit reception history information generated by associating each activation signal received by the receiving unit with the time of reception; a display control unit that displays the reception history information stored in the memory unit on a display unit; and a display condition input unit that sets display conditions for selectively displaying a desired period and a desired terminal device for the reception history information stored in the memory unit.The display control unit receives information regarding the desired period and the desired terminal device as display conditions set in the display condition input unit, and has an identification display function that extracts and displays reception history information regarding the desired terminal device within the desired period when displaying the reception history information.The display control unit, based on the performance of the reception history information generated by the memory control unit, colors the information on the display unit using at least one of the following methods to make it easier to see the transition state over time: a first display control that groups the information by alarm and recovery pair and displays it in a color-coded manner, a second display control that groups the information by date and displays it in a color-coded manner, and a third display control that groups the information by identical terminal device and displays it in a color-coded manner.

DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, preferred embodiments of the equipment control panel of the present disclosure will be described with reference to the drawings. The equipment control panel disclosed herein has a technical feature in that it has a function for appropriately displaying reception history information generated based on activation signals output from each of multiple terminal devices in response to state changes, according to the display conditions, thereby making it easy to verify the abnormality history of a specific terminal device.

[0018] Embodiment 1 First, an overview of a fire alarm system including an equipment control panel according to the present disclosure will be described. In this first embodiment, a detailed description will be given using a specific example of a case where a fire alarm receiver is used as the equipment control panel. Furthermore, the term "multiple terminal devices" in the present disclosure refers to disaster prevention devices such as sensors, terminal equipment, and transmitters, and is a general term for devices that output signals indicating operation information to the equipment control panel based on a change in state.

[0019] Fig. 1 is an overall configuration diagram of a fire alarm system including a fire receiver and multiple terminal devices according to the first embodiment of the present disclosure. Note that Fig. 1 shows the specific equipment configuration on the first floor, and the second to fifth floors are omitted because they have the same equipment configuration as the first floor.

[0020] Furthermore, the building to be monitored by the device control panel according to the present disclosure is not limited to one building, but may include cases where multiple buildings, such as Building A and Building B, are monitored.

[0021] A fire receiver 10, which corresponds to an equipment control panel, is connected to an addressable transmitter 20, fire detectors 31, 32, a detector repeater 40, and a smoke control repeater 50 via a signal line SG on each floor.

[0022] A plurality of fire detectors are connected to the detector repeater 40. Two fire detectors 41 and 42 are shown in Fig. 1. A fire door 51, a smoke exhaust machine 52, a shutter 53, and a hanging wall 54 are connected to the smoke prevention and exhaust control repeater 50.

[0023] Here, the fire detectors 31, 32 and the fire detectors 41, 42 correspond to a plurality of fire detectors that detect the occurrence of a fire in the fire monitoring area installed based on laws and regulations. A plurality of fire detectors constitutes a detector group.

[0024] In addition, the fire door 51, smoke exhauster 52, shutter 53, and hanging wall 54 operate in conjunction with the activation signals of the respective fire detectors, and function to prevent the spread of fire, smoke, etc. These multiple terminal equipments make up a terminal equipment group.

[0025] Each of the multiple fire detectors can constantly communicate with the fire control panel 10, either directly or via a detector repeater. Address information for identifying each individual fire detector is assigned to each of the multiple fire detectors in advance. Each of the multiple fire detectors can transmit an activation signal, including the address information assigned to it, to the fire control panel 10, either directly or via a detector repeater. Meanwhile, the fire control panel 10 can transmit required information to desired fire detectors, either directly or via a detector repeater, by adding address information and transmitting the information.

[0026] Furthermore, each of the multiple terminal equipment is assigned address information in advance to identify the individual terminal equipment connected to the secondary side of the smoke prevention and exhaust control repeater. Therefore, when a terminal equipment is activated, the fire control signal receiver 10 can transmit a command to activate the desired terminal equipment by adding the address information and transmitting the information. Furthermore, each terminal equipment included in the terminal equipment group can transmit an activation signal to the fire control signal receiver 10 via the smoke prevention and exhaust control repeater.

[0027] With this configuration, the fire receiver 10 receives activation signals indicating fire-related information that are output in response to status changes from a plurality of fire detectors installed in accordance with laws and regulations and from the addressable transmitters 20. Then, the fire receiver 10 issues a fire alarm or the like based on the collected activation signals, and can perform interlocked control of each piece of terminal equipment in the terminal equipment group.

[0028] Each terminal device included in the terminal device group is preset with respect to which fire detector activation signal it should operate in conjunction with. For example, by setting in advance an interlocking table that defines the correspondence between the interlocking operations of multiple fire detectors and multiple terminal devices, the fire receiver 10 can control the interlocking operations of the terminal devices based on the interlocking table in accordance with the activation signals of each of the multiple fire detectors.

[0029] Also, although not shown in the figure, the fire receiver 10 can output an alarm signal based on the received terminal device activation signal, and by linking it to an emergency broadcast device, can make detector activation broadcasts and fire broadcasts, or transmit terminal device activation information to a higher-level device via a network.

[0030] Next, the technical features of the device control panel according to the first embodiment will be described in detail. Note that each device included in the group of sensors and the group of terminal equipment shown in Fig. 1 corresponds to a terminal device that outputs an activation signal indicating fire-related information in response to a change in state in this disclosure. Furthermore, the group of transmitters made up of addressable transmitters 20 installed on each floor also corresponds to a terminal device that outputs a terminal device activation signal in response to a change in state in this disclosure.

[0031] Also, although not shown in the figure, disaster prevention equipment other than a group of sensors, a group of terminal equipment, or a group of transmitters that outputs a signal indicating terminal equipment operation information in response to a change in state is included in the terminal equipment of this disclosure.

[0032] 2 is a functional block diagram of the device control panel according to the first embodiment of the present disclosure. The device control panel according to the present disclosure has a function of receiving activation signals from a plurality of terminal devices, creating reception history information, editing the reception history information based on the display conditions set by the display condition input unit 18, and displaying information suitable for verifying the abnormality history of a specific terminal device.

[0033] In Figure 2, corresponding to Figure 1, the equipment control panel is shown as a fire receiver 10, and the multiple terminal devices 100 are shown as including a group of sensors 101, a group of terminal equipment 102, and a group of transmitters 103 installed on each floor.

[0034] The fire receiver 10, which corresponds to an equipment control panel, is configured to include a receiving unit 11, a memory control unit 12, a memory unit 13, a fire detection unit 14, an alarm unit 15, a display control unit 16, a display unit 17, and a display condition input unit 18. The equipment control panel according to the present disclosure is characterized by the display functions possessed by the display control unit 16, the display unit 17, and the display condition input unit 18, and after explaining an overview of each component, the characteristics of the display functions will be explained in detail.

[0035] The receiving unit 11 receives an activation signal output in response to a state change from each of the plurality of terminal devices 100. As an example, the following activation signals are output from the sensor group 101, terminal equipment group 102, and transmitter group 103 included in the plurality of terminal devices 100.

[0036] Each device included in the sensor group 101 outputs an activation signal in response to a change in state when it enters an activated state, indicating that it has detected a situation equivalent to a fire, or a restored state, indicating that it has recovered from an activated state.

[0037] In reality, when recovery control is performed in the fire control panel 10, all of the sensors included in the sensor group 101 are reset and placed in a recovery state. However, even if a sensor is reset, if the installation environment is in the same state as when it was activated, the sensor will immediately transmit an activation signal to the fire control panel 10.

[0038] Each device included in the terminal equipment group 102 is activated by a command from the fire control receiver 10 or by being operated by someone at the installation site, and outputs an activation signal in response to a change in state.

[0039] Each device included in the transmitter group 103 outputs an activation signal in response to a change in state when a person who discovers a fire presses a push button on the transmitter, thereby reporting the fire.

[0040] The memory control unit 12 generates data relating the activation signals sequentially received by the receiving unit 11 to the reception time, and stores the data as reception history information in the memory unit 13. At this time, the memory control unit 12 updates the reception history information so that a predetermined number of the latest data items remain in the memory unit 13.

[0041] For example, if 1000 is set as the latest fixed number, the storage control unit 12 performs an update process so that reception history information consisting of the latest 1000 pieces of data in which activation signals are associated with reception times is stored in the storage unit 13. Therefore, by performing the update process sequentially, the reception statuses of the latest fixed number of activation signals are stored in the storage unit 13 as reception history information.

[0042] The fire detection unit 14 determines whether or not a fire has occurred based on the activation signal received in real time. Furthermore, if the fire detection unit 14 determines that a fire has occurred, it can notify the fire state via the notification unit 15. Note that the determination process by this fire detection unit 14 is the same as that of the prior art, and a detailed description thereof will be omitted.

[0043] The display control unit 16, the display unit 17, and the display condition input unit 18 are the main components of the device operation panel according to the present disclosure, and will be described in detail below. The display control unit 16 has the following functions to perform a display suitable for verifying the abnormality history of a specific terminal device based on the reception history information stored in the memory unit 13.

[0044] Function 1: A function of receiving, via the display condition input unit 18, a desired period for extracting reception history information and display conditions for selecting and displaying a desired terminal device.

[0045] The desired period and the setting values ​​for the desired terminal device can be set, for example, by the operator of the fire control receiver 10 via the display condition input unit 18. The desired period can be set by setting the most recent time period, or by setting the start date and time and the end date and time. For example, the period can be set as the most recent week, or as a day with a set date.

[0046] Function 2: When displaying reception history information, if a desired period is set using the display conditions set in Function 1, the reception history information is displayed only within the desired period, and if a desired terminal device is set, the display is limited to the desired terminal device.

[0047] For example, if the desired terminal device is set as a display condition for "fire detector 42 on the 5th floor," display control unit 16 extracts history information related to "fire detector 42 on the 5th floor" from the received history information stored in storage unit 13. Then, display control unit 16 causes display unit 17 to display the extracted history information.

[0048] If the extracted history information cannot be displayed on one screen, the display control unit 16 displays it across multiple screens. However, the most recent history information is displayed on the first screen. The display control unit 16 can also vary the density, saturation, brightness, etc. of the characters or background to be displayed for each display condition, allowing the information to be distinguished according to the display conditions.

[0049] When displaying the extracted reception history information, the display control unit 16 can change the density, saturation, brightness, etc. of the characters or background by using display methods such as changing the character color, changing the background color, or displaying a specific mark, and display the information in different colors according to the passage of time.

[0050] The desired terminal device to be selected is not limited to one, and the operator can select multiple terminal devices. For example, by selecting two devices, "Fire detector 42 on the 5th floor" and "Fire detector 41 on the 5th floor" located nearby, the operator can display the reception history information of the two selected devices on the display unit 17, making it easy to compare the histories of both devices.

[0051] Furthermore, when multiple terminal devices are selected as desired terminal devices via the display condition input unit 18, the display control unit 16 can display the terminal devices in different colors according to their respective configurations, and can also select color coding in chronological order.

[0052] Next, specific examples of display by the display control unit 16 will be described with reference to Fig. 3 to Fig. 7. In order to more clearly explain the display function according to the present disclosure, a detailed description will be given below using a specific example in which the buildings to be monitored are two buildings, Building A and Building B, each of which has one to five floors.

[0053] Fig. 3 is an explanatory diagram showing a first display example by the display control unit 16 according to the first embodiment of the present disclosure. Fig. 3 illustrates the latest reception history information stored in the storage unit 13. The reception history information shown in Fig. 3 is stored in the storage unit 13 after each item of terminal device, reception / control content, and reception date / time is updated sequentially with the latest data as No. 1.

[0054] If a desired period and a desired terminal device are not set as display conditions, the most recent 10 pieces of data from the reception history information stored in the storage unit 13 will be displayed as one screen of data on the display unit 17 as a first display example. Data from No. 11 onwards will be scrolled by switching to the second screen or later.

[0055] 4 is an explanatory diagram showing a second display example by the display control unit 16 according to the first embodiment of the present disclosure. In FIG. 4, the desired terminal device selected to be displayed on the display unit 17 is set as the display condition to be "fire detector 42 on the fifth floor of building A," and a desired period is not set. In this state, the reception history information extracted in accordance with this display condition is illustrated.

[0056] Then, the most recent 10 data items among the reception history information are extracted according to the display conditions and displayed as one screen of data on the display unit 17. If there is data No. 11 or later, the data items are scrolled by switching to the second screen or later.

[0057] In the first display example shown in Figure 3 above, among the received history information displayed as the most recent 10 data, data No. 6 corresponds to the desired terminal device, "Fire detector 42 on the 5th floor of building A." However, the status of data No. 11 and onward exists in the history, but cannot be seen on the first screen.

[0058] In contrast, in the second display example shown in Figure 4, the desired terminal device is set as the display condition to "fire detector 42 on the 5th floor of building A," so the most recent 10 pieces of data related to "fire detector 42 on the 5th floor of building A" are displayed and are identified and displayed as reception history information on the first screen.

[0059] Therefore, an operator who has set the desired terminal device as the display condition can visually check the second display example shown in Figure 4, limiting it to "fire detector 42 on the 5th floor of building A," and compare the transition states of the most recent 10 pieces of data on one screen, thereby verifying whether there is any reason why false alarms are occurring frequently.

[0060] 4, in order to make it easier to visually recognize the transition state over time, pairs of alarm and recovery are grouped and color-coded. In this way, when displaying the extracted reception history information, the display control unit 16 can change the density, saturation, brightness, etc. of the characters or background by using display methods such as changing the character color, changing the background color, or displaying a specific mark, thereby displaying the information in different colors according to the passage of time.

[0061] Fig. 5 is an explanatory diagram showing a third display example by the display control unit 16 according to the first embodiment of the present disclosure. While Fig. 4 above illustrates a case where pairs of alarm and recovery are grouped and displayed in different colors, Fig. 5 illustrates a case where pairs of alarm and recovery are grouped and displayed in different colors according to date.

[0062] An operator viewing the third display example shown in Figure 5 can easily infer that, since "Fire detector 42 on the 5th floor of Building A" tends to be activated consecutively on October 7, 2022 and July 3, 2022, they should investigate whether there are any events related to the dates, times, or installation locations of those events.

[0063] When the display control unit 16 determines based on the reception history information stored in the memory unit 13 that an activation signal has been input from the same terminal device to the fire control device 10 a predetermined number of times or more, the terminal device may be automatically displayed in a color that makes it easy to recognize on the display unit 17. In this way, the operator of the fire control device 10 can easily recognize which terminal device is not in a steady state but is in an abnormal state, rather than checking on the display unit 17 a list of terminal devices that have issued activation signals in chronological order.

[0064] To realize such a display function, the display control unit 16 identifies the same terminal device that has output an activation signal a predetermined number of times or more within a desired period based on the performance of the reception history information generated by the storage control unit 16. Then, the display control unit 16 automatically displays the identified same terminal device in a color that makes it easy to recognize on the display unit 17.

[0065] 6 is an explanatory diagram showing a fourth display example by the display control unit 16 according to the first embodiment of the present disclosure. The fourth display example shown in FIG. 6 illustrates a state in which the most recent 10 data items of reception history information are displayed when the desired period selected to be displayed on the display unit 17 is set as the display condition to "July 3, 2022, 1st" and the desired terminal device is not set.

[0066] In the first display example shown in Figure 3 above, the reception history information displayed as the most recent 10 data does not include data for the desired period, "July 3, 2022, 1st," and the status on "July 3, 2022" cannot be seen on the first screen.

[0067] In addition, in the second display example shown in Figure 4 above and the third display example shown in Figure 5 above, since "Fire detector 42 on the 5th floor of building A" is set as the desired terminal device, two records related to "Fire detector 42 on the 5th floor of building A" are displayed on July 3, 2022, but other terminal devices and the third and subsequent records cannot be seen on the first screen.

[0068] In contrast, in the fourth display example shown in Figure 6, the desired period is set as the display condition to "July 3, 2022, 1st," so the most recent 10 pieces of data for all terminal devices on "July 3, 2022, 1st" are extracted and displayed as reception history information on the first screen.

[0069] Therefore, an operator who has set a desired period as a display condition can visually check the fourth display example shown in Figure 6, limiting it to "July 3, 2022, 1 day" and compare the transition states of the most recent 10 data points on one screen, and verify whether there is any cause for frequent false alarms.

[0070] 6, in order to make it easier to visually recognize the transition state of each terminal device over time, the terminal devices are grouped into groups and color-coded. In this way, when displaying the extracted reception history information, the display control unit 16 can change the density, saturation, brightness, etc. of the characters or background by using a display method such as changing the character color, changing the background color, or displaying a specific mark, thereby displaying the information in different colors according to the terminal device.

[0071] An operator viewing the fourth display example shown in Figure 6 can easily infer that, since "fire detector 42 on the 5th floor of building A" tended to activate consecutively on July 3, 2022, and "fire detector 41 on the 5th floor of building A" also activated on the same day, they should investigate whether there are any incidents caused by the locations of these detectors.

[0072] When multiple activation signals are received from a certain terminal device (detector) and a terminal device (detector) installed nearby, the display unit 17 may automatically extract only those terminal devices from the reception history information and display them. This type of display is effective in the event of a fire, but also makes it easier to recognize when there is a source of a false alarm in the monitored area.

[0073] 7 is an explanatory diagram showing a fifth example of display by the display control unit 16 according to the first embodiment of the present disclosure. The fifth example of display shown in FIG. 7 illustrates a state in which the most recent 10 data items of reception history information are displayed when the desired period selected to be displayed on the display unit 17 is set as the display conditions to "July 3, 2022, 1st" and the desired terminal device is set as "fire detector 42 on the 5th floor of building A."

[0074] In the second display example shown in Figure 4 above and the third display example shown in Figure 5 above, although "fire detector 42 on the 5th floor of building A" is set as the desired terminal device, the desired period has not been set, so all history related to "fire detector 42 on the 5th floor of building A" is displayed.

[0075] In addition, in the fourth display example shown in Figure 6 above, although the desired period is set to "1st July 3rd, 2022," the desired terminal device has not been set, so all history related to "1st July 3rd, 2022" is displayed.

[0076] In contrast, in the fifth display example shown in Figure 7, the display conditions are such that the desired period is set to "July 3, 2022, 1st" and the desired terminal device is set to "Fire detector 42 on the 5th floor of Building A," so the most recent 10 pieces of data related to "Fire detector 42 on the 5th floor of Building A" on "July 3, 2022, 1st" are extracted and displayed as reception history information on the first screen.

[0077] Therefore, an operator who has set the desired period and desired terminal device as the display conditions can visually check the fifth display example shown in Figure 7, and compare the transition states of the most recent 10 pieces of data on one screen, limited to "July 3, 2022, 1st day" and "Fire detector 42 on the 5th floor of Building A," to verify whether there is any reason why false alarms are occurring frequently.

[0078] 7, in order to make it easier to visually recognize the transition state over time, pairs of alarm and recovery are grouped and displayed in different colors. In this way, when displaying the extracted reception history information, the display control unit 16 can change the density, saturation, brightness, etc. of the characters or background by using display methods such as changing the character color, changing the background color, or displaying a specific mark, thereby displaying the information in different colors according to the passage of time.

[0079] An operator who views the fifth display example shown in Figure 7 can understand the transitional state in which "fire detector 42 on the 5th floor of building A" was activated on July 3, 2022, and can easily infer that they should verify whether there is any incident caused by the installation location of "fire detector 42 on the 5th floor of building A."

[0080] 7 illustrates an example in which the desired period is set to "July 3, 2022, 1st" and the desired terminal device is set to "fire detector 42 on the 5th floor of building A" as a display condition, but the setting of display conditions in the present disclosure is not limited to this. For example, it is also possible to set multiple time periods as the desired period, or to set multiple terminal devices as the desired device.

[0081] Specifically, it is conceivable to limit the desired period to 10:00 to 12:00 and set a time period spanning three days as the desired period, or to set five "fire detectors 42" installed in the same locations on the first to fifth floors of Building A as the desired terminal devices. By making such settings, it becomes possible to infer the cause of false alarms from the perspective of trends in time periods and installation locations, etc.

[0082] As described above, according to the first embodiment, the distinguishable display function based on the display conditions makes it possible to easily identify terminal devices that frequently output activation signals. As a result, it becomes easier to visually recognize terminal devices that may be repeatedly outputting activation signals, and it is possible to easily identify abnormality histories caused by false alarms without repeatedly switching screens.

[0083] In particular, the device operation panel according to the first embodiment has a technical feature in that it is equipped with a display control unit that appropriately displays reception history information according to the display conditions, the reception history information being generated based on the activation signals output from each of the multiple terminal devices in response to a change in state, and the following effects 1 and 2 are obtained.

[0084] Effect 1: By setting the desired period and desired terminal device as the display conditions, it is possible to extract and display reception history information related to the desired terminal device for the desired period. The desired period is not limited to the most recent time period, but can also be set to a past time period, making it easy to verify terminal devices that are repeatedly operating based on the identification display results.

[0085] Effect 2: When displaying history information according to the display conditions, it is possible to display it in a color-coded manner according to the passage of time or the type of terminal device. As a result, it is possible to easily understand the transition state of the activation signal from the terminal device that is repeatedly operating, and to easily verify the tendency and frequency of the activation signal output.

[0086] A supplementary explanation will be given below of a method other than switching to the next screen to check when there are more than 10 history items. Fig. 8 is a functional block diagram of the device operation panel according to the first embodiment of the present disclosure, which is different from Fig. 2. Compared with the functional block diagram shown in Fig. 2, the functional block diagram shown in Fig. 8 further includes a display expansion unit 19 to which an external display unit 17a can be connected.

[0087] The display expansion unit 19 has a function of editing the most recent history information consisting of more than 10 pieces of data in accordance with the display performance of the external display unit 17a so that more than 10 pieces of data can be viewed on one screen, and displaying the edited results on the external display unit 17a.

[0088] For example, if the external display unit 17a has the display capability to display 20 items on one screen, the display expansion unit 19 can display the 14 items of data shown in Figures 4 and 5 on the external display unit 17a as one screen.

[0089] In other words, the display expansion unit 19 can be connected to an external display unit 17a having display capabilities capable of displaying on one screen a number of extended display data items that exceeds the number of screen display data items of reception history information that can be displayed on one screen on the display unit 17, and has the function of editing reception history information consisting of the number of extended display data items to match the display capabilities of the external display unit 17a and displaying the edited results on the external display unit 17a.

[0090] As a result, by visually checking the display contents of the external display unit 17a, the operator can compare the transition states of the most recent data consisting of more than 10 expanded display data items displayed on one screen, and more efficiently verify whether there is any cause for the frequent occurrence of false alarms.
