Description

Technical Field

[0001] This application relates to the field of fire protection technology, and in particular to a method for displaying fire alarm information, a fire display panel, and a fire alarm system. Background Technology

[0002] A fire alarm display panel is a fire alarm display device that can be installed on a floor or in an independent fire compartment. When a fire occurs in a corresponding fire compartment or floor, the fire alarm controller receives the alarm information and sends the alarm signal to the fire alarm display panel in the area where the fire occurred. The fire alarm display panel then displays the fire alarm information and simultaneously issues an audible and visual alarm signal.

[0003] Normally, each fire compartment is equipped with a fire alarm display panel. In existing technology, when a fire alarm occurs, the display panel only shows the fire alarm information for its own compartment and issues an alarm to notify personnel in that compartment to evacuate. Because the fire alarm display panel only shows fire alarm information for its own compartment and cannot display fire alarm information for other compartments, the display range is limited. If a project has multiple fire compartments, personnel in that compartment cannot promptly obtain fire alarm information from other compartments, limiting early warning and timely evacuation, and potentially causing personal injury and property damage.

[0004] In the relevant technologies, the fire alarm display panel only displays fire alarm information for the current zone and cannot display fire alarm information across zones or circuits, resulting in a limited range of fire alarm information display. Currently, no effective solution has been proposed. Summary of the Invention

[0005] Therefore, it is necessary to provide a fire alarm information display method, a fire display panel, and a fire alarm system to address the aforementioned technical problems.

[0006] In a first aspect, embodiments of this application provide a method for displaying fire alarm information, the method comprising:

[0007] Upon receiving a fire alarm message, retrieve the configuration parameters;

[0008] Based on the configuration parameters, the corresponding display strategy is determined;

[0009] The fire alarm information is filtered based on the display strategy, and it is determined whether to display the fire alarm information.

[0010] In one embodiment, the configuration parameters include policy matching parameters, and determining the corresponding display policy based on the configuration parameters includes:

[0011] Based on the strategy matching parameters in the configuration parameters, the corresponding display strategy is determined.

[0012] In one embodiment, the fire alarm information includes first device information corresponding to the fire alarm device, the configuration parameters include second device information of the fire display panel, and the step of filtering the fire alarm information based on the display strategy and determining whether to display the fire alarm information includes:

[0013] Based on the display strategy and the second device information of the fire display panel, at least one corresponding matching information is determined;

[0014] Based on the matching result of the at least one matching information and the first device information, it is determined whether to display the fire alarm information.

[0015] In one embodiment, the matching information includes first address information, the first device information includes second address information, and the fire alarm information is displayed when the first address information matches the second address information.

[0016] In one embodiment, the fire alarm information includes first device information corresponding to the fire alarm device, and the configuration parameters include third address information of at least one target area; the step of filtering the fire alarm information based on the display strategy and determining whether to display the fire alarm information includes:

[0017] Based on the display strategy, at least one third address information for a target region is determined;

[0018] Based on the matching result of the third address information and the first device information, it is determined whether to display the fire alarm information.

[0019] In one embodiment, the first device information includes second address information, and if a third address information matching the second address information exists, the fire alarm information is displayed.

[0020] Secondly, embodiments of this application also provide a fire display panel, the fire display panel comprising:

[0021] The acquisition module retrieves configuration parameters upon receiving a fire alarm message;

[0022] The first determining module is used to determine the corresponding display strategy based on the configuration parameters;

[0023] The second determining module is used to filter the fire alarm information based on the display strategy and determine whether to display the fire alarm information.

[0024] In one embodiment, the fire display panel further includes:

[0025] The two-bus communication module is used to receive the fire alarm information.

[0026] In one embodiment, the fire display panel further includes:

[0027] The storage module is used to store configuration parameters;

[0028] The display module is used to display the fire alarm information.

[0029] Thirdly, embodiments of this application also provide a fire alarm system, including a main alarm device and at least one slave alarm device, wherein the main alarm device and at least one slave alarm device include a controller and a fire display panel as described in the second aspect above, which is connected to the controller, and the controller is used to configure the configuration parameters;

[0030] The slave alarm device is used to receive the fire alarm information and transmit the fire alarm information to the master alarm device;

[0031] The main alarm device is used to transmit the fire alarm information to each of the slave alarm devices.

[0032] The aforementioned fire alarm information display method, fire display panel, and fire alarm system, upon receiving fire alarm information, acquire configuration parameters, then determine a corresponding display strategy based on these parameters, further filter the fire alarm information based on the display strategy, and determine whether to display the fire alarm information. This solves the problem in related technologies where fire display panels only display fire alarm information from their own zone and cannot display fire alarm information from other zones, resulting in a limited display range. This application determines the corresponding display strategy through configuration parameters. Based on this strategy, the fire display panel can display fire alarm information from both its own zone and other zones simultaneously. For example, it can simultaneously display fire alarm information from the current floor, adjacent floors, or other address floors. Because different zones may belong to different circuits, this enables the display of cross-zone and cross-circuit fire alarm information, expanding the warning range. Simultaneously, the fire display panel emits audible and visual alarms, facilitating timely evacuation and minimizing losses in the event of a fire.

[0048] This embodiment provides a method for displaying fire alarm information, such as... Figure 1 As shown, the method includes:

[0049] Step S101: Upon receiving a fire alarm message, obtain the configuration parameters.

[0050] When a fire occurs, the fire alarm system reports the fire alarm information to other alarm devices, such as point-type photoelectric smoke detectors, point-type heat detectors, and manual alarm buttons. If the alarm device is a slave device, it then forwards the fire alarm information to the master alarm device. The master alarm device then distributes the fire alarm information to the fire display panels of all zones under each slave device. When the fire display panel receives the fire alarm information, it retrieves the configuration parameters.

[0051] Step S102: Determine the corresponding display strategy based on the configuration parameters.

[0052] The display strategy in this embodiment is determined based on configuration parameters. Multiple configuration parameters can be set to provide a variety of display strategy options.

[0053] Step S103: Filter the fire alarm information based on the display strategy and determine whether to display the fire alarm information.

[0054] Fire alarm information is filtered according to the display strategy and then displayed on the fire display panel. The specific address where the fire occurred can be located through the fire alarm information.

[0055] Through steps S101 to S103, upon receiving fire alarm information, configuration parameters are obtained, and a corresponding display strategy is determined based on these parameters. The fire alarm information is then filtered based on the display strategy to determine whether to display it. This solves the problem in related technologies where fire alarm display panels only display fire alarm information from the current zone and cannot display fire alarm information from other zones, resulting in a limited display range. This application, by configuring parameters to determine the corresponding display strategy, allows for setting the area range where fire alarm information needs to be displayed. Therefore, the fire alarm display panel can display not only fire alarm information from the current zone but also fire alarm information from other zones, such as simultaneously displaying fire alarm information from the current floor, adjacent floors, or other address floors. This enables cross-zone and cross-circuit fire alarm information display, expanding the warning range. Simultaneously, the fire alarm display panel emits audible and visual alarms, facilitating timely evacuation and minimizing losses in the event of a fire.

[0056] In one embodiment, the configuration parameters include policy matching parameters, and determining the corresponding display policy based on the configuration parameters includes: determining the corresponding display policy based on the policy matching parameters in the configuration parameters, the process of which is as follows: Figure 2 As shown:

[0057] Step S201: Receive fire alarm information and obtain configuration parameters.

[0058] Step S202: Obtain the strategy matching parameters from the configuration parameters.

[0059] Upon receiving a fire alarm message, the policy matching parameter is retrieved from the configuration parameters. The policy matching parameter is represented by Para, which can be set to a natural number. The number and value of Para can be customized.

[0060] Step S203: Determine the corresponding display strategy based on the strategy matching parameter in the configuration parameters.

[0061] For example, when Para=0, the corresponding display strategy is to display fire alarm information for all zones;

[0062] When Para=1, the corresponding display strategy is to display fire alarm information for this partition;

[0063] When Para=2, the corresponding display strategy is to display fire alarm information of adjacent partition devices;

[0064] When Para=3, the corresponding display strategy is to display fire alarm information from adjacent partitions and the current partition;

[0065] When Para=4, the corresponding display strategy is to display the fire alarm information of the target partition;

[0066] When Para=5, the corresponding display strategy is to display the fire alarm information of the target partition and the current partition;

[0067] When Para=6, the corresponding display strategy is to display fire alarm information for the three target zones;

[0068] When Para=7, the corresponding display strategy is to display the fire alarm information of the three target partitions and the current partition;

[0069] When Para>=8, the default behavior is Para=1, and only fire alarm information for this partition is displayed.

[0070] Each floor can be set up as a zone, and each zone is equipped with a fire display panel to receive and display fire alarm information, issue alarm signals, and notify personnel in the zone to evacuate.

[0071] In one embodiment, the fire alarm information includes first device information corresponding to the fire alarm device, and the configuration parameters include second device information of the fire display panel.

[0072] The first device information of a fire alarm device is the UC code. For example, the UC code of a certain fire alarm device is 0x0360519901, where x represents any number. The parsing result of this UC code is 03 6 05 19901, where 03 represents building 3, 6 represents unit 6, 05 represents floor 5, 199 represents the address code, and 01 represents the type of fire alarm device. Through this first device information, we can know the installation configuration of the fire alarm device, that is, the fire alarm device is installed in unit 6, floor 5 of building 3, the address code is 199, and the device type is 1.

[0073] The second device information of the fire display panel is also a UC code. For example, the UC code of the second device information of a certain fire display panel is 0x0280720006, where x represents any number. The parsing result of this UC code is 02 8 07 20006, where 02 represents building 02, 8 represents unit 8, 07 represents floor 07, 200 represents the address code, and 06 represents the device type of the fire display panel. Through this second device information, we can know the installation configuration of the fire display panel, that is, the fire display panel is installed in unit 8, floor 7 of building 02, the address code is 200, and the device type is 6.

[0074] The process of filtering the fire alarm information based on the display strategy and determining whether to display the fire alarm information includes the following steps: Figure 3 As shown:

[0075] Step S301: Based on the display strategy and the second device information of the fire display panel, determine at least one corresponding matching information;

[0076] Step S302: Based on the matching result of the at least one matching information and the first device information, determine whether to display the fire alarm information.

[0077] In one example embodiment, the second device information UC code of the fire display panel is 0x51606xxx06, where x represents any number. When Para = 3, the corresponding display strategy is determined to be that the fire display panel displays fire alarm information from adjacent zones and the current zone. Based on the above display strategy and the second device information 0x51606xxx06 of the fire display panel, three matching information is determined: 0x51605xxxxx, 0x51606xxxxx, and 0x51607xxxxx, where x represents any number. Then, based on the matching result of these three matching information and the first device information, it is determined whether to display the fire alarm information. That is, it is determined whether the first device information corresponding to the fire alarm device is 0x51605xxxxx, 0x51606xxxxx, or 0x51607xxxxx. If so, the corresponding fire alarm information is displayed on the fire display panel; otherwise, the corresponding fire alarm information is not displayed on the fire display panel.

[0078] In one embodiment, the matching information includes first address information, the first device information includes second address information, and the fire alarm information is displayed when the first address information matches the second address information.

[0079] The first address information is the specific address where the fire display panel is installed, which is obtained from the first 5 digits of the UC code parsing result of the fire display panel, representing the building number, unit number, and floor number where the fire display panel is installed. The second address information is the specific address where the fire alarm equipment is installed, which is obtained from the first 5 digits of the UC code parsing result of the fire alarm equipment.

[0080] In one example embodiment, the second device information UC code of the fire display panel is 0x51606xxx06. When Para=1, the corresponding display strategy is that the fire display panel only displays the fire alarm information of this zone, and the corresponding matching information can be determined to be 0x51606xxxxx. The first 5 bits of the UC code parsing result of this matching information are 51606, that is, the first address information is 51606. It is determined whether the second address information corresponding to the fire alarm device is 51606. If it is, the corresponding fire alarm information is displayed on the fire display panel; if not, the corresponding fire alarm information is not displayed on the fire display panel. When Para=2, the corresponding display strategy is that the fire display panel displays the fire alarm information of adjacent zones, and the corresponding matching information can be determined to be 0x51605xxxxx and 0x51607xxxxx. The first 5 bits of the UC code parsing result of the matching information are 51605 and 51607, respectively, that is, the first address information is 51605 and 51607, respectively. The system checks if the second address information corresponding to the fire alarm device is 51605 or 51607. If so, the corresponding fire alarm information is displayed on the fire display panel; otherwise, it is not displayed. When Para = 3, the corresponding display strategy can be to display the fire alarm information of the fire alarm devices in this zone and adjacent zones on the fire display panel. The corresponding matching information can be determined to be 0x51605xxxxx, 0x51606xxxxx, and 0x51607xxxxx. The first 5 bits of the UC code parsing result of this matching information are 51605, 51606, and 51607, which means the first address information is 51605, 51606, and 51607 respectively. The system then checks if the second address information corresponding to the fire alarm device is 51605, 51606, or 51607. If so, the corresponding fire alarm information is displayed on the fire display panel; otherwise, it is not displayed. The strategy matching parameter can also be set to Para=0, which means the display strategy will not filter fire alarm information and will display all fire alarm information.

[0081] This embodiment obtains strategy matching parameters upon receiving a fire alarm, then determines a corresponding display strategy based on these parameters. Based on the display strategy and the second device information of the fire alarm display panel, it determines at least one matching piece of information. Based on the matching result of the at least one matching piece of information and the first device information, it determines whether to display the fire alarm information. This allows for the display of fire alarm information from both the current floor and adjacent floors. For example, in this embodiment, when a fire alarm occurs on the 7th floor of Unit 6, Building 51, or on the 5th floor of Unit 6, Building 51, the fire alarm display panel installed on the 6th floor of Unit 6, Building 51 can issue an alarm, promptly notifying personnel in the affected area to take evacuation measures and minimize losses.

[0082] In one embodiment, the fire alarm information includes first device information corresponding to the fire alarm device, and the configuration parameters include third address information of at least one target area; the step of filtering the fire alarm information based on the display strategy and determining whether to display the fire alarm information includes the following steps, such as... Figure 4 The following is stated:

[0083] Step S401: Based on the display strategy, determine the third address information of at least one target area;

[0084] The third address information of the target area can be represented by three parameters: AreaN_1, AreaN_2, and AreaN_3, where N is a natural number greater than 0. These three parameters represent the building number, unit number, and floor number of the target area, respectively. For example, Area1_1 = 04, Area1_2 = 04, Area1_3 = 04, representing the 4th floor of unit 4 in building 04; Area1_1 = 04, Area1_2 = 0, Area1_3 = 04, representing the 4th floor of all units in building 04; Area1_1 = 04, Area1_2 = 04, Area1_3 = 0, representing all floors of unit 4 in building 04. If Area1_2 = 0, the target area is a specific building, all units, and a specific floor; if Area1_3 = 0, the target area is a specific building, a specific unit, and all floors. The configuration parameters can set the third address information of one or more target areas, and the third address information of one or more target areas is determined based on the display strategy.

[0085] Step S402: Based on the matching result of the third address information and the first device information, determine whether to display the fire alarm information.

[0086] In one embodiment, the first device information includes second address information, and if a third address information matching the second address information exists, the fire alarm information is displayed.

[0087] For example, when Para = 4, the corresponding display strategy is to display fire alarm information for the target zone. Based on this strategy, the third address information of the target area is determined to be Area1_1 = 07, Area1_2 = 04, and Area1_3 = 05, indicating that the specific address of the target zone is Unit 4, Building 07, Floor 05. Then, it is determined whether the second address information of the fire alarm device is 070405. If yes, it means that the third address information matches the second address information of the fire alarm device, and the corresponding fire alarm information is displayed. If not, it means that the third address information does not match the second address information of the fire alarm device, and the corresponding fire alarm information is not displayed.

[0088] When Para = 5, the corresponding display strategy is to display the fire alarm information of the target zone and the current zone. Based on this display strategy, the third address information of the target area is determined to be Area1_1 = 07, Area1_2 = 04, Area1_3 = 05, indicating that the specific address of the target zone is Unit 4, 5th floor of Building 07. Then, it is determined whether the second address information of the fire alarm device is 070405. If yes, it means that the third address information matches the second address information of the fire alarm device, and the corresponding fire alarm information is displayed. If not, it means that the third address information does not match the second address information of the fire alarm device, and the corresponding fire alarm information is not displayed. According to the display strategy, the fire display panel also displays the fire alarm information of the current zone. Assuming that the UC code of the fire display panel of the current zone is 0x04206xxx06, where x represents any number, it can be seen that when the second address information of the fire alarm device is 04206, it means that there is a match, and the fire display panel displays the corresponding fire alarm information.

[0089] When Para = 6, the corresponding display strategy is to display fire alarm information for three target zones. Based on this strategy, the third address information for these three target zones is determined as Area1_1 = 04, Area1_2 = 04, Area1_3 = 04; Area2_1 = 05, Area2_2 = 05, Area2_3 = 05; Area3_1 = 06, Area3_2 = 06, Area3_3 = 06, representing the addresses of these three target zones as Unit 4, Floor 4 of Building 04, Unit 5, Floor 5 of Building 05, and Unit 6, Floor 6 of Building 06, respectively. Then, it is determined whether the second address information of the fire alarm device is 04404, 05505, or 06606. If yes, it indicates that the third address information matches the second address information of the fire alarm device, and the corresponding fire alarm information is displayed. If not, it indicates that the third address information does not match the second address information of the fire alarm device, and the corresponding fire alarm information is not displayed.

[0090] like Figure 5As shown, when Para = 7, the corresponding display strategy is to display the fire alarm information of the three target zones and the current zone. Based on this display strategy, the third address information of the three target zones is determined to be Area1_1 = 04, Area1_2 = 04, Area1_3 = 04; Area2_1 = 05, Area2_2 = 05, Area2_3 = 05; Area3_1 = 06, Area3_2 = 06, Area3_3 = 06, which respectively represent the addresses of the three target zones as Unit 4, Floor 4 of Building 04, Unit 5, Floor 5 of Building 05, and Unit 6, Floor 6 of Building 06. Then, it is determined whether the second address information of the fire alarm device is 04404, 05505, or 06606. If yes, it means that the third address information matches the second address information of the fire alarm device, and the corresponding fire alarm information is displayed; if not, it means that the third address information does not match the second address information of the fire alarm device, and the corresponding fire alarm information is not displayed. In this embodiment, according to the display strategy, the fire display panel also displays the fire alarm information of this partition. Assuming that the UC code of the fire display panel of this partition is 0x04206xxx06, where x represents any number, it can be seen that when the second address information of the fire alarm device is 04206, it means that there is a match, and the fire display panel displays the corresponding fire alarm information.

[0091] In this embodiment, the fire alarm display panel is installed at Unit 2, Floor 6, Building 04. By configuring at least one third address information of the target area in the parameter values, when a fire alarm occurs, the fire alarm display panel of this zone can not only display the fire alarm information of this zone, i.e., Unit 2, Floor 6, Building 04, but also the fire alarm information of Unit 4, Floor 4, Building 04, Unit 5, Floor 5, Building 05, and Unit 6, Floor 6, Building 06. This realizes that it can display the fire alarm information of both this zone and other zones, and at the same time issue an audible and visual alarm, expanding the warning range and making it easier to warn people to evacuate in time and reduce losses when a fire occurs. In other words, if a user's address is Unit 2, Floor 6 of Building 04, and this user is also concerned about fire alarm information on Unit 4, Floor 4 of Building 04, Unit 5, Floor 5 of Building 05, and Unit 6, Floor 6 of Building 06, then by configuring parameters and display strategies, when a fire alarm occurs on Unit 4, Floor 4 of Building 04, Unit 5, Floor 5 of Building 05, or Unit 6, Floor 6 of Building 06 in the target area, the corresponding fire alarm information will be displayed on the fire alarm display panel installed on Unit 2, Floor 6 of Building 04 in this zone, and the user will receive an alarm message. The user can then immediately know the fire alarm and its specific address, and take appropriate measures as early as possible, such as evacuating to a safe area and reporting the fire in a timely manner.

[0092] like Figure 6The diagram shows a flowchart of a fire alarm information display method according to another embodiment of this application. First, it is determined whether the fire display panel has received fire alarm information. If not, the fire display panel operates normally. If fire alarm information is received, a Para value is obtained. Then, based on the obtained Para value, a corresponding display strategy is determined. When Para = 0, the corresponding display strategy is to display fire alarm information for all zones; when Para = 1, the corresponding display strategy is to display fire alarm information for the current zone; when Para = 2, the corresponding display strategy is to display fire alarm information for adjacent zone devices; when Para = 3, the corresponding display strategy is to display fire alarm information for both adjacent zones and the current zone. That is, when Para = 1, Para = 2, or Para = 3, based on the display strategy and the second device information of the fire display panel, at least one matching information is determined. It is then determined whether the at least one matching information matches the first device information. If they match, the fire alarm information is displayed; otherwise, the fire alarm information is not displayed. When Para=4, the corresponding display strategy is to display the fire alarm information of the target partition; when Para=5, the corresponding display strategy is to display the fire alarm information of the target partition and the current partition; when Para=6, the corresponding display strategy is to display the fire alarm information of three target partitions; when Para=7, the corresponding display strategy is to display the fire alarm information of three target partitions and the current partition. That is, when Para=4, Para=5, Para=6, or Para=7, based on the display strategy, the third address information of at least one target area is determined, and it is determined whether the third address information matches the first device information. If they match, the fire alarm information is displayed; if they do not match, the fire alarm information is not displayed.

[0093] This embodiment provides a fire display panel, such as Figure 7 As shown, the device includes:

[0094] The acquisition module 610 acquires configuration parameters upon receiving a fire alarm message;

[0095] The first determining module 620 is used to determine the corresponding display strategy based on the configuration parameters;

[0096] The second determining module 630 is used to filter the fire alarm information based on the display strategy and determine whether to display the fire alarm information.

[0097] The fire alarm display panel provided in this embodiment obtains configuration parameters upon receiving fire alarm information, determines a corresponding display strategy based on these parameters, further filters the fire alarm information based on the display strategy, and determines whether to display the fire alarm information. This solves the problem in related technologies where fire alarm display panels only display fire alarm information from the current zone and cannot display fire alarm information from other zones, resulting in a limited display range. This application determines the corresponding display strategy through configuration parameters, allowing the fire alarm display panel to display fire alarm information using multiple strategies. Therefore, the fire alarm display panel can display not only fire alarm information from the current zone but also fire alarm information from other zones, such as simultaneously displaying fire alarm information from the current floor, adjacent floors, or other address floors. This enables the display of cross-zone and cross-circuit fire alarm information, while simultaneously issuing audible and visual alarms to expand the warning range, facilitating timely evacuation and minimizing losses in the event of a fire.

[0098] In some embodiments, the fire display panel further includes a two-bus communication module for receiving the fire alarm information. For example... Figure 8 As shown, the two-bus communication module includes:

[0099] Bus 1 (710) and Bus 2 (720) are used to connect to the fire alarm controller. Fuse 730 prevents current consumption when a hardware malfunction generates a large current, limiting the current draw and preventing a drop in the bus voltage that could affect other devices on the two buses. TVS 740 primarily provides electrostatic discharge and lightning surge protection. The rectifier bridge 750 is non-polarized, meaning the positive and negative lines of the two buses can be arbitrarily connected to the terminals of Bus 1 (710) and Bus 2 (720) without polarity distinction. The anti-reverse diode 760 primarily provides reverse protection. The energy storage capacitor 770 stores some energy; when the equipment requires current, the energy in the energy storage capacitor 770 is consumed first to prevent multiple devices on the bus from drawing energy and lowering the bus voltage. Voltage divider resistors R1 (780) and R2 (790) mainly divide the bus signals, converting them into an RXD signal with a voltage of V. RXD The bus voltage is V bus V RXD = (R2 / (R1+R2))*V bus Assuming the bus signal voltage is 24V and the voltage division ratio is 7:1, the RXD voltage is approximately 3.4V, which is a high level, and the bus signal is interpreted as 1. If the bus signal voltage is 2V, the RXD voltage is approximately 0.3V, which is a low level, and the bus signal is interpreted as 0. The fire display panel includes a microcontroller. In this embodiment, the microcontroller used is the Huada HC32L170 chip, which communicates with the two-bus communication module via the UART0 serial port.

[0100] In some embodiments, the fire display panel further includes:

[0101] The storage module is used to store configuration parameters;

[0102] Configuration parameters can be stored in a Flash memory chip and are retained even after power failure. The configuration parameters can be directly retrieved after power-on or reset. The Flash memory chip communicates with the microcontroller using the common SPI communication protocol.

[0103] The display module is used to display the fire alarm information.

[0104] The screen module can be a display screen used to display filtered fire alarm information. The display screen communicates with the microcontroller using the common IIC protocol.

[0105] In some embodiments, the first determining module 620 is further configured to determine the corresponding display strategy based on the strategy matching parameters in the configuration parameters.

[0106] In some embodiments, the second determining module 630 is further configured to: determine at least one matching information based on the display strategy and the second device information of the fire display panel, wherein the fire alarm information includes first device information of the corresponding fire alarm device and the configuration parameters include second device information of the fire display panel; and determine whether to display the fire alarm information based on the matching result of the at least one matching information and the first device information.

[0107] In some embodiments, the second determining module 630 is further configured to display the fire alarm information when the matching information includes first address information and the first device information includes second address information, provided that the first address information matches the second address information.

[0108] In some embodiments, the second determining module 630 is further configured to: determine the third address information of at least one target area based on the display strategy; and determine whether to display the fire alarm information based on the matching result of the third address information and the first device information.

[0109] In some embodiments, the second determining module 630 is further configured to display the fire alarm information if the first device information includes second address information and a third address information matching the second address information exists.
