Description

Technical Field

[0001] The present invention relates to the technical field of fire control systems, in particular to a fire linkage logic verification method based on simulation and a fire linkage logic verification system based on simulation. Background Art

[0002] In the existing technology, the testing of the fire linkage host mainly relies on the actual operation and linkage verification of the physical equipment on site. The testing process usually includes the following steps:

[0003] On-site triggering of alarm signals: Manually or automatically triggering smoke detectors, temperature detectors and other equipment to simulate fire alarm scenarios.

[0004] Observe the response of the fire host: After receiving the alarm signal, the fire host will link the relevant fire-fighting equipment according to the preset logic.

[0005] Verify the working status of linkage equipment: Check whether the linkage equipment (such as cutting off non-fire power supply, starting fire fans, opening smoke exhaust valves, etc.) is working as expected.

[0006] Although traditional on-site verification methods can test fire linkage hosts, they rely entirely on the actual operation of physical equipment on site, resulting in a complex and inefficient testing process and an inability to meet the needs of complex scenarios. Specifically, they have the following problems and limitations:

[0007] (1) Time-consuming and labor-intensive

[0008] Complex operation: The testing process requires technicians to manually operate the equipment on site, especially in large buildings involving multiple areas and equipment. The operation is cumbersome and time-consuming.

[0009] Repeated testing: Complex linkage logic may require multiple tests, further increasing time and labor costs.

[0010] Reason: Reliance on manual operations and lack of automation means make it impossible to quickly complete multiple rounds of testing.

[0011] Linkage test problems: If problems occur during linkage testing (such as logical errors, abnormal device responses, etc.), modifications must be made before retesting, which will extend the test cycle.

[0012] Reason: The linkage test relies on the response of the on-site equipment. Once a problem is found, the equipment needs to be reconfigured or debugged, which is a cumbersome and time-consuming process.

[0013] (2) Safety hazards

[0014] False triggering of equipment: During the test, real firefighting equipment may be falsely triggered (such as lighting going out, fire shutter doors lowering, etc.). Frequent testing may cause equipment damage or personnel panic.

[0015] Test environment limitations: Testing needs to be conducted in high-risk areas (such as high-rise buildings, underground spaces, etc.), which increases safety risks.

[0016] Reason: Testing needs to be carried out in a real environment, and the impact on the on-site environment and equipment cannot be avoided.

[0017] (3) High cost

[0018] Equipment loss: Testing relies on physical equipment. Frequent operation may cause equipment loss and increase maintenance costs.

[0019] Demand for professional and technical personnel: The testing process requires the participation of professional and technical personnel, which further increases labor costs.

[0020] Reason: It relies on physical equipment and professional personnel to operate, and cannot reduce costs through technical means. Summary of the Invention

[0078] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0079] Reference Figure 1, shows a flowchart of a fire linkage logic verification method based on simulation provided in an embodiment of the present invention, which may specifically include the following steps:

[0080] Step 101: Obtain a fire host project file to be tested selected by a user; the fire host project file to be tested includes basic information of at least one fire host, linkage logic rules, and a fire equipment point table;

[0081] Step 102: read and parse the fire host engineering file to be tested, and display the basic information of the fire host;

[0082] Step 103: Enter the fire host simulation test interface, respond to the target fire host and test mode selected by the user, perform linkage operation on the fire equipment connected to the target fire host according to the linkage logic rules, and output the linkage operation result and linkage instruction; the linkage operation result includes the target output device;

[0083] Step 104: simulate the actual firefighting action of the target output device according to the linkage instruction, and output and display the linkage execution result.

[0084] In an optional embodiment of the present invention, the test mode includes a manual test mode, which enters the fire host simulation test interface, responds to the target fire host and test mode selected by the user, performs linkage calculations on the fire equipment connected to the target fire host according to linkage logic rules, and outputs linkage calculation results and linkage instructions, including:

[0085] Enter the fire host simulation test interface, respond to the target fire host and the target simulated alarm device selected by the user, and simulate the target simulated alarm device to trigger the alarm signal;

[0086] Perform linkage operation according to the alarm signal of the target simulated alarm device and the linkage logic rule, and output the linkage operation result and linkage instruction of the target simulated alarm device.

[0087] In an optional embodiment of the present invention, the test mode includes a single-point traversal test mode, which enters the fire host simulation test interface, responds to the target fire host and test mode selected by the user, performs linkage operations on the fire equipment connected to the target fire host according to the linkage logic rules, and outputs linkage operation results and linkage instructions, including:

[0088] Enter the fire host simulation test interface, respond to the single-point traversal test mode selected by the user, and simulate each simulated alarm device to trigger an alarm signal;

[0089] The linkage operation is performed according to the alarm signal and linkage logic rules of each analog alarm device, and the linkage operation result and linkage instruction of each analog alarm device are output.

[0090] In an optional embodiment of the present invention, the fire host engineering file to be tested is read and parsed, and basic information of the fire host is displayed, including:

[0091] Read and parse the fire host engineering file to be tested to obtain the basic information of the fire host, linkage logic rules, and fire equipment point table;

[0092] The basic information of the fire host is checked for accuracy. After confirming that the key configuration parameters in the basic information of the fire host are correct, the basic information of the fire host is displayed.

[0093] In an optional embodiment of the present invention, the method further includes:

[0094] In response to the user triggering the host reset function, the data and status of the fire host simulation test are restored to the initial values.

[0095] The present invention develops a fire host simulator based on a fire linkage logic verification method of simulation, which can simulate the behavior and linkage logic of a real fire host, including equipment alarm, linkage equipment startup, etc.

[0096] Reference Figure 2 The fire host simulator based on the fire linkage logic verification method of simulation is composed of multiple functional modules. Each module works closely together to realize the various functions of the simulated fire host. The specific functions of each module are as follows:

[0097] The Host Information Module reads fire host data and parses the device point table and logic table for all hosts in the project. The device point table contains detailed information on the various firefighting devices connected to the host, including the device name, number, type, and installation location. The logic table records the logic rules for the linkage between firefighting devices, such as which devices are triggered to activate under what conditions. The module systematically organizes and categorizes this data, preparing it for subsequent analysis and presentation.

[0098] The simulation host module consists of multiple sub-functional units. The host selection and simulated alarm device selection unit, which can be interactively linked to virtual input devices using drop-down menus or button groups, allows users to select devices for simulated alarms. The alarm list is a data storage area that records information about simulated alarms in tabular form. It is connected to the simulated alarm device selection unit and the linkage logic processing unit to provide data support for subsequent processing. The activation output list is also a data storage area that stores information about output devices to be activated after linkage logic operations. It is connected to the linkage logic processing unit and virtual output module devices to control the operation of these virtual output modules. The host reset button is a separate control button connected to the core processing unit of the simulation host module. Pressing it restores the simulation host to its initial state. The single-point traversal test unit is used to test each input device individually. It is connected to the virtual input device and the linkage logic processing unit to ensure that each input device can be independently verified. The linkage logic processing unit is the core processing unit of the simulation host module. It receives alarm signals from the virtual input devices, performs operations based on the preset fire linkage logic, and initiates updates to the output list and the operation of the virtual output modules.

[0099] Virtual input devices, including fire detectors (such as smoke detectors and temperature detectors), manual alarms, and input modules (which detect fire alarm input signals), are connected to the simulated alarm device selection unit and the linkage logic processing unit. These virtual input devices simulate the alarm trigger sources in real fire scenarios and provide a variety of test signals for fire linkage logic testing.

[0100] These simulated alarm devices can realistically simulate normal operating conditions and various alarm situations, and can accurately present scenes such as detector alarms, manual button triggering alarms, and input modules receiving and transmitting signals.

[0101] Virtual output module equipment: including sound and light alarms, fire shutter doors, fire broadcasts, etc. These virtual output module devices simulate the actions of real fire equipment according to the instructions of the simulation host module, realizing the simulation of fire linkage effects.

[0102] Once the virtual input device triggers an alarm, the associated output module device can respond quickly, realizing a series of linkage operations in actual scenarios such as activating the sound and light alarm, closing the fire shutter door, and opening the fire fan damper, providing a more realistic and comprehensive simulation environment for fire simulation testing.

[0103] Reference Figure 3 The specific process of the fire host simulator to conduct fire linkage logic testing is as follows:

[0104] Reference Figure 4 、 Figure 5Select the host project: On the Fire Host Simulator interface, select the host project file to be tested through a drop-down menu or file selection dialog box. This project file contains relevant configuration information for the corresponding fire host, such as the host model, linkage logic rules, and device point table. This step is critical to ensure that the selected host project file is accurate. If the incorrect selection is made, subsequent test results will not truly reflect the performance of the target fire host.

[0105] Reference Figure 6 , read host data and display basic host information: The simulator reads the data in the selected host project file and transfers basic information such as the host number and host description to the host information module for display. At the same time, the host information module should also have the function of analyzing abnormalities in key host configuration information, performing preliminary analysis of the read host basic information, such as determining whether the key configuration information in the host basic information is correct.

[0106] Reference Figure 7 , enter the simulation host: After completing data reading and display, the system enters the simulation host operation interface, providing the user with an operating environment for simulation testing. This interface should be simple and easy to operate to ensure that users can quickly become familiar with and perform various operations.

[0107] Selecting a test mode: Users can choose between manual test or single-point traversal test mode on the interface. In manual test mode, users can manually trigger the alarm status of virtual input devices as needed; in single-point traversal test mode, the system automatically tests each virtual input device in sequence. When selecting a test mode, users should make an appropriate choice based on the test objectives and requirements. For example, when conducting a comprehensive test of a newly installed fire protection system, single-point traversal test mode is preferred to ensure that every device is verified. Manual test mode is more appropriate for targeted testing of specific devices or linkage logic.

[0108] Reference Figure 8 、 Figure 9 Selecting an alarm device (in manual test mode): If manual test mode is selected, the user uses the simulated alarm device selection unit on the simulated host module to select the virtual input device to trigger the alarm, such as clicking a fire detector or manual alarm. This step requires the user interface to be interactive, allowing the user to accurately select the target device and avoid misoperation.

[0109] Reference Figure 10Single-point traversal test (in single-point traversal test mode): In single-point traversal test mode, the system automatically selects each virtual input device for testing in a preset order. The system records the start and end time of each test for subsequent analysis. During the traversal process, ensure that the test is complete and no virtual input device is missed.

[0110] Reference Figure 11 The fire alarm linkage logic is then activated and the output list is activated. Whether testing manually or with a single-point traversal test, when a virtual input device triggers an alarm, the simulation host module's linkage logic processing unit performs operations based on the preset fire alarm linkage logic rules. For example, if the smoke detector and the manual alarm also sound, the linkage logic should activate the audible and visual alarms, start the fire alarm announcement, and lower the fire shutters. The linkage logic processing unit then sends the calculation results to the activation output list. The key to this process lies in the accuracy and completeness of the linkage logic rules, which must be appropriately set based on actual fire protection needs.

[0111] Output list displays linked devices: Activating the output list transmits information about enabled virtual output module devices to the user interface for display, allowing users to intuitively see which devices are linked and enabled. The display interface should clearly display information such as device name and startup status for easy observation and recording.

[0112] Reference Figure 12 After a single-point traversal test, a test table can be generated and saved as an Excel file. During the test, the simulator records detailed information for each test, including the device that triggered the alarm, the device that initiated the linkage, and the test linkage logic location, generating a test list. After the test, the user can save the test list as an Excel file for subsequent analysis.

[0113] Host Reset: After each test is completed, the user can click the Host Reset button to restore the simulated host to its initial state and prepare for the next test. The host reset operation should ensure that all data and status of the simulated host module are restored to their initial values ​​to avoid interference with subsequent tests.

[0114] The following are two examples provided by the present invention:

[0115] Example 1: Fire detector triggering linkage in manual test mode

[0116] Scene Setting

[0117] The fire protection system at a subway station required targeted testing. The focus was on verifying the coordinated operation of the firefighting equipment when two fire detectors within the same fire zone sounded. Manual test mode was selected to simulate a real-world fire alarm in a specific area.

[0118] Steps

[0119] Reference Figure 13 , select the host project: In the fire host simulator operation interface, select the "Subway Station Host Project" file through the drop-down menu. This file contains the detailed configuration and linkage logic rules of each fire equipment in the subway station.

[0120] Reference Figure 14 , read host data and display information: the simulator reads the selected project file, displays two fire hosts in the host information module, and displays information such as network online status and detection grounding status.

[0121] Enter the simulated host: After completing the data reading, the system enters the simulated host operation interface.

[0122] Reference Figure 15 、 16 , select test mode: After selecting the host in the operation interface, click to select the device to simulate the alarm and enter the device list.

[0123] Select alarm equipment: In the simulation alarm equipment selection unit, select one smoke detector each in the women's locker room and the men's locker room as the equipment to trigger the alarm.

[0124] Triggering alarms and linkage logic operations: Clicking the simulated alarm confirmation button simulates the smoke detector sending an alarm signal. Upon receiving the signal, the linkage logic processing unit in the simulated host module performs operations based on pre-set linkage logic rules. These rules specify that when a smoke detector in a specific area sounds, 18 firefighting devices in that area are activated, including access control release, elevator to the safe floor, and EPS forced activation.

[0125] Reference Figure 17 , the output list shows the linkage devices: the startup output list shows that 18 fire protection devices including access control release, elevator to safe floor, EPS forced start, etc. have been started.

[0126] Host reset: Click the host reset button to restore the simulated host to its initial state.

[0127] Example 2: Comprehensive testing of fire protection equipment in the entire building in single-point traversal test mode

[0128] Scene Setting

[0129] A subway depot has 10 fire protection system hosts installed. A comprehensive inspection of the fire protection equipment in the entire depot is required to ensure that each device is functioning properly and that the linkage logic is accurate. In this case, the single-point traversal test mode is used.

[0130] Steps

[0131] Reference Figure 18, Select the host project: Select the "Vehicle Depot Fire Host Project" file in the operation interface. This file covers the detailed information and linkage rules of all fire-fighting equipment in the vehicle depot.

[0132] Reference Figure 19 , read the host data and display information: After the simulator reads the file, 10 fire hosts are displayed in the host information module, and information such as network online status and detection grounding status is displayed.

[0133] Enter the simulated host: enter the simulated host operation interface.

[0134] Reference Figure 20 、 21 , select the test mode: click the "Single Point Traversal Test" button to start a comprehensive test. During the test, the button displays the current host test progress percentage. After completion, the results are saved to the project directory "Single Point Traversal Test.xlsx" file.

[0135] Single-point traversal testing process: The system simulates all detectors, manual alarms, and input modules individually triggering alarm signals according to the device order in the point table. The linkage logic processing unit performs calculations based on the linkage rules. According to "4.1.6 of the Design Specification for Automatic Fire Alarm Systems GB50116-2013, fire protection equipment requiring linkage control by the automatic fire alarm system shall have its linkage trigger signal comprised of an 'AND' logical combination of the alarm signals from two independent alarm triggering devices." If a single detector or manual alarm triggers an alarm, activating the audible and visual alarms, cutting off the fire power supply, or starting the fire fan, the linkage conditions for the devices are not met, resulting in an erroneous linkage.

[0136] Reference Figure 22 Exception handling: When testing the smoke sensor at 4-1-T08 on the second-floor stairwell, it was found that the smoke sensor triggered an alarm, which then triggered multiple sound and light alarms. At this time, the record table displays this information and indicates the logic location. The tester can further check for any logic problems based on the logic location number and make corrections.

[0137] Technical effects of the present invention:

[0138] This invention builds a logic verification environment for a virtual fire control unit based on simulation. The simulator simulates the triggering state of each independent input device, thereby verifying the fire control unit's response. Given the logical relationship between the linkages within the fire protection system, this verification of individual device alarms is crucial. This approach effectively prevents situations where a single device could erroneously trigger a linkage or cause a fire shutter door to operate, thus avoiding unnecessary panic and effectively ensuring the integrity and reliability of the linkage logic.

[0139] By building a virtual fire control unit logic verification environment based on simulation, rapid testing is achieved without relying on on-site equipment, significantly shortening testing cycles, reducing manual operations, and improving testing efficiency. Testing is conducted entirely within the simulation verification environment, avoiding false device triggering and high-risk operations, eliminating safety hazards associated with on-site testing, and ensuring the safety of personnel and equipment. This reduces reliance on physical equipment, reduces equipment wear and maintenance costs, and reduces the frequency of on-site testing, thereby lowering testing costs.

[0140] Taking the 30 linkage mode test scenarios at a subway station as an example, the specific effects are as follows:

[0141] The traditional method tests 30 modes and a total of 60 linkages (including the linkage of two detectors and the linkage of detectors and manual alarms). A single scenario (the linkage of two detectors) requires 2 minutes to trigger the device, 3 minutes for the host to check the results, and 1 minute for reset confirmation, with a total time of 6 minutes per time. The 60 tests total 360 minutes (6 hours).

[0142] By using the simulator test of the present invention, the manual full-process test is compressed to 1 minute per test, and the total time consumed for 60 tests is only 60 minutes (1 hour), which is 83% shorter than the test cycle of the traditional method.

[0143] The present invention also supports traversal testing of all host input devices (such as fire detectors, manual alarms, input modules, etc.) to ensure the integrity and reliability of the linkage logic. (Assuming that the station has 200 detectors and 20 manual alarms):

[0144] The traditional method takes 1 minute to test one detector, 1 minute to confirm whether there is a false trigger and reset it, and the total time is 2 minutes per time. The test of 200 fire detectors accumulates to 400 minutes. One manual alarm takes 10 seconds, and 1 minute to confirm whether there is a false trigger and reset it, and the total time is 70 seconds per time. The test of 20 manual alarms accumulates to 23 minutes. Testing all fire detectors and manual alarms takes a total of 423 minutes.

[0145] When the simulator test is adopted by the present invention, the traversal test of all devices is completed in less than 1 minute. Compared with the traditional method, the simulator test efficiency is improved by about 99.8%, that is, the test time is only 0.24% of the traditional method, achieving a nearly 100-fold efficiency leap.

[0146] In terms of cost, the traditional method of testing mode linkage, as described above, requires three people working together, with a labor cost of 18 man-hours. However, the simulator testing method of the present invention only requires one person, saving 17 man-hours compared to the traditional method, a labor cost reduction of 94.4%. Virtual testing replaces physical device triggering (such as smoke detectors and fire shutters), eliminating the need to build a test platform and eliminating equipment testing costs.

[0147] It should be noted that for the sake of simplicity, the method embodiments are described as a series of actions. However, those skilled in the art should be aware that the embodiments of the present invention are not limited by the order of the actions described, because according to the embodiments of the present invention, certain steps can be performed in other orders or simultaneously.
