Description

Technical Field

[0001] The present invention relates to the field of building fire safety, and in particular to an intelligent point arrangement and linkage programming algorithm based on evacuation control. Background Art

[0002] With the continuous expansion of the scale of modern buildings and the increasing complexity of their functions, traditional fire protection systems have gradually exposed many limitations in terms of the accuracy of fire alarms, the refinement of linkage control, and the efficiency of emergency evacuation. For example, it is often difficult for traditional systems to perform differentiated linkage programming triggers based on the combined status of conditional equipment set on different floors, and in complex building structures, it is impossible to ensure the precise response of evacuation action equipment and the effective isolation between areas, which may lead to serious problems such as evacuation confusion, waste of resources, and rescue delays when a fire occurs. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an intelligent point layout and automated linkage programming method based on evacuation control, which realizes intelligent point layout on the building plan, and accurately controls the emergency response of the host, power supply and lamps by receiving real-time input signals, so as to provide a fast and safe evacuation route for personnel in emergency situations.

[0004] In order to solve the above technical problems, the present invention provides an intelligent point arrangement and automatic linkage programming method based on evacuation control, comprising the following steps: S1: Arrange firefighting equipment or evacuation route equipment on the firefighting building plan. The equipment is anchored at the center, with the positive direction of the Y axis pointing downward and the positive direction of the X axis pointing rightward. When the firefighting equipment is selected for arrangement, the icon is a square, and the icon size is equal to the current zoom factor multiplied by the icon base value. When the evacuation route equipment is selected for arrangement, the equipment icon is a rectangle, and the aspect ratio needs to be considered. If the width is longer than the height, the width is equal to the current zoom factor multiplied by the icon base value multiplied by the width divided by the height, and the height is equal to the current zoom factor multiplied by the icon base value, the mouse coordinate x minus half of the difference between the width and the height, and the mouse coordinate y plus half of the height. If the height is longer than the width, the height is equal to the current zoom factor multiplied by the icon base value multiplied by the height divided by the width, and the width is equal to the current zoom factor multiplied by the icon base value, the mouse coordinate y minus half of the difference between the height and the width, and the mouse coordinate x plus half of the width. Set the rotation angle, determine the position of the equipment icon in the firefighting building plan, and display it by dotting. After scaling the firefighting building plan, recalculate the position and size of the equipment icon and offset it. S4: After receiving the fire alarm signal, the evacuation controller runs the signal analysis and conditional device identification interface, analyzes the signal source according to the set communication protocol format and data analysis algorithm, and analyzes the detailed identification information of the smoke detector according to the set communication protocol format and data analysis algorithm; S5: query the relational database to determine whether the conditional device to which the smoke detector belongs exists in the set linkage programming. If so, extract the relevant information of the linkage programming from the database and load the information into the linkage programming execution engine data structure in the memory; S6: Start the condition judgment and linkage programming verification module, check the conditional devices in the linkage programming one by one, and make judgments based on the preset alarm status judgment standards. If the number of devices in the alarm state reaches or exceeds the set count value, the system enters the linkage programming compliance judgment and trigger decision process; if it is found in the condition judgment process that the number of devices in the alarm state does not reach the count value, or if it is found in the linkage programming compliance judgment process that the linkage programming has been triggered, the system will process it based on the corresponding exception handling logic and fault diagnosis program.

[0005] Furthermore, after step S6, the following steps are also included: for the triggered linkage programming, the system performs status recording and log update operations, and records the detailed information of the triggering event.

[0006] Furthermore, the detailed information includes trigger time, trigger source and linkage programming execution status.

[0007] Furthermore, the linkage programming compliance judgment and trigger decision process includes: the system first checks the trigger status mark of the linkage programming. If the mark shows that it has not been triggered, the system generates a detailed startup instruction list based on the action device sequence and trigger order in the linkage programming.

[0008] Further, in step S1, the fire fighting equipment includes fire fighting equipment, emergency lighting and / or centralized power supply.

[0009] Furthermore, the linkage program determines whether the linkage trigger conditions are met based on pre-configured conditional equipment, specified alarm conditions, operators, and dynamic calculations, including dynamic matching of multiple conditional equipment information, and configuring operators to implement multi-dimensional conditional judgments. Operators include logical operators and advanced operators. Users can flexibly set conditional equipment, alarm conditions, and action logic at runtime. Users can customize linkage logic based on the granularity of buildings, floors, and partitions.

[0010] Further, the operators include "and" and "or", and advanced operators include "count" and "every several".

[0011] Furthermore, when the number of devices in the alarm state reaches or exceeds the set count value, it is determined that the evacuation equipment on this floor needs to be switched to the emergency working mode, triggering the action devices predefined in the linkage programming. Different conditional devices are assigned unique trigger weights and priority sequences in the linkage programming logic.

[0012] Furthermore, the action devices include routes, outputs, hosts, building partitions, hosts, power supplies, and lamps.

[0013] Furthermore, the conditional equipment includes a fire host, a fire circuit, a fire device and / or a passive input.

[0014] The technical effect of the present invention is that the intelligent point distribution method of the present invention maintains the consistency of the scaling factor during continuous point distribution, avoiding the confusion of point distribution positions due to different scaling ratios. In addition, the scaling operation is performed based on the center point, ensuring that the device can still accurately reflect its actual installation position on the scaled plan, avoiding the accuracy of the evacuation plan affected by position offset.

[0015] The automated linkage programming method of the present invention is based on an intuitive page operation mode, allowing users to complete the configuration of linkage logic by dragging condition devices and action devices. The algorithm significantly simplifies the programming process, avoiding the tedious steps and misremembering problems of debuggers manually entering device address numbers. Through an intuitive operation interface, complex linkage logic is quickly generated, the efficiency of device linkage processing is improved, and the human error rate is reduced.

DETAILED DESCRIPTION

[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a set position, be constructed and operated in a set position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figure 1-Figure 12 As shown in the figure, the intelligent point arrangement and automatic linkage programming method based on evacuation control of the present invention includes the following steps: The present invention can intelligently arrange the icons of fire equipment, emergency lighting, centralized power supply and other fire equipment on the fire building plan. First, click and select the equipment to be arranged from the equipment list, then move the mouse to the fire building plan and click, and the equipment arrangement is completed. If there are other unarranged equipment in the equipment list, the user can continue to arrange the equipment until the last equipment in the list is arranged, and then the arrangement is automatically exited. If the user wants to exit the arrangement midway, move the mouse out of the fire building plan area.

[0022] The point distribution function covers the reasonable layout and positioning of power supplies, lamps, routes and fire equipment. The information of each point distribution, including structured data such as buildings, floors, and partitions, is stored in the corresponding annotation table. At the same time, the location information of the point distribution is represented by the x and y coordinates of the coordinate system with the upper left corner as the origin, and the relevant scaling factor and icon rotation angle are attached to ensure the accurate management and display of the point distribution information.

[0023] like Figure 1-Figure 2 As shown, the present invention can intelligently arrange evacuation routes on the fire building plan, specify the evacuation route direction (up, down, left, right), fill in a certain number and then move the mouse onto the fire building plan and click, and complete the arrangement of the specified number of route icons from the click position to the specified direction at intervals of 10 pixels, and the arrangement is completed.

[0024] The present invention performs a wall detection on the evacuation route point arrangement. When a position is clicked to create a specified number of route icons in a specified direction and the distance to the edge of the fire building plan is insufficient, the user is prompted that the distance is insufficient and the point cannot be arranged.

[0025] After the fire-fighting equipment and evacuation routes of the present invention are intelligently arranged based on evacuation control, when the fire-fighting building plan is scaled, the equipment icons will not be offset from the original positions.

[0026] The embodiment of the intelligent point distribution of the present invention is as follows: the point distribution device takes the center as the anchor point, the downward direction is the positive direction of the Y axis, and the right direction is the positive direction of the X axis, so that when the fire building plan is scaled, the icon will not be offset. However, it must be compatible with the coordinates of the graphic display system of the fire control room (with the upper left corner as the anchor point), so coordinate conversion is required.

[0027] When the user selects fire equipment, emergency lighting, centralized power supply and other equipment for deployment, the equipment icon is a square. The size of the equipment icon is equal to the current zoom factor multiplied by the icon base value. The mouse coordinate x needs to be added with half of the width, and the mouse coordinate y needs to be added with half of the height. Set the rotation angle, and finally determine the position of the equipment icon in the fire building plan, and display it with dots.

[0028] When the user selects the evacuation route equipment for deployment, the equipment icon is a rectangle, and the aspect ratio needs to be considered. If the width is longer than the height, the width is equal to the current zoom factor multiplied by the icon base value multiplied by the width divided by the height. The height is equal to the current zoom factor multiplied by the icon base value, the mouse coordinate x minus half of the difference between the width and the height, and the mouse coordinate y plus half of the height. If the height is longer than the width, the height is equal to the current zoom factor multiplied by the icon base value multiplied by the height divided by the width, the mouse coordinate y minus half of the difference between the height and the width, and the mouse coordinate x plus half of the width. Set the rotation angle, and finally determine the position of the equipment icon in the fire building plan, and display it with dots. As shown below Figure 4 shown.

[0029] After scaling the fire building plan, this algorithm needs to recalculate the position and size of the equipment icon and then offset it without changing its relative position to the fire building plan. The scaling ratio is ratio, the zoom ratio is 1.1, and the zoom ratio is 0.9. The mouse coordinates are offsetX and offsetY. The size of the equipment icon before scaling is recorded as scaleBeginWidth and scaleBeginHeight. After scaling, the size of the equipment icon is width and height. According to half of the width / height scaling factor, the coordinates of the center point of the equipment icon origin.x and origin.y are calculated. Then, according to the scaling factor of the distance between the mouse coordinates and the equipment icon coordinates, the coordinates of the center point of the equipment icon are subtracted to calculate the offset x and y of the upper left corner of the equipment icon. Finally, the coordinate X is equal to the original coordinate X minus the x offset minus half of the width increment during scaling, and the coordinate Y is equal to the original coordinate Y minus the y offset minus half of the height increment during scaling. After the new coordinates of the equipment icon are known, reset them. Figure 5 shown.

[0030] When a fire occurs on site, the fire equipment is marked with red dots on the plan view. When a fault occurs, the fire equipment, evacuation power supply and evacuation lamps are marked with yellow dots on the plan view. If the linkage programming is triggered at this time, the evacuation power supply, evacuation lamps and evacuation routes flash on the plan view according to the linkage programming rules, providing users with a safe escape route.

[0031] The automatic linkage programming method of the present invention comprises the following steps: The present invention can use professional fire protection system design software (such as AutoCAD Fire Protection or SprinkCAD) to accurately configure parameters and comprehensively calibrate the status of conditional equipment (fire host, fire circuit, fire equipment and passive input) according to the detailed architectural drawings, functional zoning planning and fire protection code requirements of the building during the system deployment and initialization stage. At the same time, according to the fire risk assessment report and evacuation plan of the building, the automatic linkage programming method is used to construct a complex linkage programming logic, and each conditional equipment and the corresponding action equipment are associated and configured according to the predetermined evacuation strategy and safety rules, and the linkage programming information is stored in a high-reliability storage system to establish a complete version management and data backup mechanism.

[0032] When the system is running, the smoke detector continuously monitors the smoke concentration in the surrounding environment in real time based on its internal high-precision smoke sensor element. Once any two smoke detectors detect abnormal smoke concentration, they will report a fire alarm signal according to the predetermined communication protocol.

[0033] like Figure 3 As shown in the figure, after obtaining the digital fire alarm signal, the evacuation controller runs the signal analysis and device identification interface, and analyzes the detailed identification information of the signal source (i.e., smoke detector) according to the set communication protocol format and data analysis algorithm, including device number, alarm time, alarm type, and alarm event. Then, the relational database is queried to determine whether the conditional device to which the smoke detector belongs exists in the set linkage programming. If so, the relevant information of the linkage programming is extracted from the database, including all conditional device lists, operators, count value settings, corresponding action device information, and detailed descriptions of linkage rules involved, and this information is loaded into the linkage programming execution engine data structure in the memory for subsequent rapid processing.

[0034] The linkage programming module includes the configuration of conditional devices, operators, alarm types and action devices. In this module, several special tables are designed first: linkage programming table, conditional device table and action device table. The linkage programming table stores annotation information, operators, number of trigger conditions and their status related to linkage conditions; the conditional device table records the detailed information of all configured conditional devices, including device type, status and its association with linkage programming; and the action device table stores action device information related to linkage programming, including device type, device information, etc.

[0035] The system starts the condition judgment and linkage programming verification module, checks the conditional devices in the linkage programming one by one, and makes judgments based on the preset alarm status judgment criteria. If the number of alarm devices reaches or exceeds the set count value, the system enters the linkage programming compliance judgment and trigger decision process.

[0036] In the linkage programming compliance judgment process, the system first checks the trigger status mark of the linkage programming. If the mark shows that it has not been triggered, the system generates a detailed startup instruction list based on the action device sequence and trigger order in the linkage programming.

[0037] If the number of alarm devices is found to have not reached the count value during the condition judgment process, or if the linkage programming is found to have been triggered during the linkage programming compliance judgment process, the system will process it according to the corresponding exception handling logic and fault diagnosis program, and it is considered that the action device does not need to be triggered this time. For the triggered linkage programming, the system will record the status and update the log, and record the detailed information of the triggering event (including trigger time, trigger source, linkage programming execution status, etc.) in the log for subsequent accident analysis and system optimization.

[0038] The evacuation controller monitors multiple types of signals from conditional devices such as fire controllers and passive inputs in real time through the external CAN port. The signal types include alarm conditions (such as fire alarms, start signals) and status signals. Receiving information is the first step in linkage programming. Regarding the analysis of alarm conditions, the analysis data content includes: information type, alarm event, alarm type, etc. According to the pre-configured conditional devices, specified alarm conditions, operators and dynamic calculations, whether the linkage trigger conditions are met: Signal linkage analysis algorithm: supports dynamic matching of information of various conditional devices (such as fire controllers, fire points, passive inputs, etc.), and realizes multi-dimensional condition judgment through flexible configuration of operators.

[0039] Operator design: supports basic logical operators (AND, OR) and advanced operators (count, every few).

[0040] Dynamic configuration mechanism: allows users to flexibly set conditional devices, alarm conditions and action logic at runtime without hard coding.

[0041] Partitioned linkage programming mechanism: A linkage programming method that supports partitioned configuration is proposed, and users can customize the linkage logic based on the granularity of buildings, floors, and partitions.

[0042] The present invention can configure linkage programming when deploying points, which is mainly divided into two ways: 1. deploying points first and then configuring programming; 2. deploying points and configuring linkage programming at the same time.

[0043] Method 1: The main application scenario is that users configure linkage programming for deployed devices. Select the linkage programming to be configured on the homepage, open the building plan to display the device icons, click the linkage programming condition device or action device selection button, move the mouse into the building plan, click to select the configured device, and add a new device record to the condition device or action device list in the corresponding linkage programming to complete the linkage programming configuration.

[0044] Method 2: The main application scenario is that users configure linkage programming for undeployed devices and complete deployment at the same time. Select the linkage programming to be configured on the homepage, open the building plan to display the device icon, click the linkage programming condition device or action device to start deployment button, click to select the device in the device list, move the mouse to the building plan and click it, the device is successfully deployed and the linkage programming configuration is completed.

[0045] like Figure 6 As shown, this linkage programming scheme is designed to start the emergency mode of the whole machine through passive input signals.

[0046] like Figure 7 As shown, this linkage programming scheme is designed to trigger the power supply to enter emergency mode through the synergy of "smoke detection and hand alarm" events.

[0047] like Figure 8 As shown, this linkage programming scheme triggers the circuit to enter the emergency mode after any two smoke detectors in the set condition device meet the set counting conditions.

[0048] like Fig. 9 As shown, this linkage programming scheme is designed to trigger the lamps and routes in a partition to enter emergency mode after any two smoke detectors in the partition meet the counting conditions.

[0049] The following is a specific embodiment of the present invention: for example, when any two smoke detectors on a certain floor meet the counting conditions, the power supply, lamps and routes on the floor are triggered to enter the emergency mode.

[0050] To deploy points, you need to upload the building plan in advance and select images of different resolutions to upload. The supported resolutions are (800, 2410, 4229, 7076, 10800). Before deploying points, select the floor to obtain the corresponding building plan. When loading, the default display resolution is dynamically set according to the current browser window size. When the mouse is used to zoom in on the plan, if the current image width exceeds the next resolution threshold, the current resolution image is destroyed, the image of the resolution is loaded, and its size and position are kept consistent with the destroyed image. The user does not perceive the switch and the display effect is enhanced. When the mouse is used to zoom out on the plan, if the current image width is lower than the previous resolution threshold, the current resolution image is destroyed, the image of the resolution is loaded, and its size and position are kept consistent with the destroyed image. The user does not perceive the switch and the display effect is weakened.

[0051] When any two smoke detectors on the 1st floor of Building 1 and the 1st floor of Building 2 detect that the smoke concentration exceeds the preset threshold, a fire alarm signal will be immediately generated and uploaded according to the set controller local area network protocol. As the core control hub of the system, the evacuation controller first executes the parsing algorithm to perform complex decoding and feature extraction operations on the signal after receiving the fire alarm signal, so as to eliminate useless messages in the signal transmission process and parse out the key information in the signal, such as the precise address of the alarm device, the alarm timestamp, and the alarm type. Subsequently, based on the pre-built large-scale equipment relationship database (using the relational database management system MySQL for storage and management, the database covers the physical connection relationship of the equipment, the logical association rules, and the role definition in different linkage programming), it is accurately determined whether the equipment that generates the fire alarm signal is included as a key condition equipment in the set linkage programming logic sequence, such as Fig.10 The analysis of the alarm situation is shown.

[0052] In the conditional equipment cluster on Floor 1 of Building 1, when the number of devices in alarm state reaches or exceeds the preset count value, the system relies on the built-in automated linkage programming method to determine that the evacuation equipment (evacuation host, evacuation power supply, evacuation circuit, evacuation lamps, evacuation route) on this floor needs to switch to emergency working mode, thereby accurately triggering the action devices pre-defined in the linkage programming.

[0053] Different conditional devices are given unique trigger weights and priority sequences in a complex linkage programming logic network, ensuring that when a fire occurs, evacuation actions can be taken according to the actual situation of the building (such as the direction of fire spread and the distribution of personnel gathering areas), achieving isolation and functional independence between evacuation areas, and effectively avoiding system-level chain reactions caused by local failures or misoperations.

[0054] The action equipment mainly focuses on the evacuation equipment clusters on the 1st floor of Building 1 and the 1st floor of Building 2, covering evacuation hosts with intelligent power management and load balancing functions, evacuation power supplies with high energy density storage technology and redundant backup design, evacuation circuits that build a reliable power transmission network, evacuation lamps with high brightness and long life characteristics and support intelligent dimming and guidance functions, and an evacuation route identification system that dynamically generates evacuation route instructions based on the building's spatial layout and personnel evacuation path planning algorithm.

[0055] like Fig.11 The alarm is shown as follows. Once the trigger conditions of the linkage programming are confirmed to be met, the system will locate the action device in the programming and take corresponding emergency measures according to the type of action device. The specific implementation is as follows: If the action device is the host: the system will instruct the host to enter the emergency state, and at the same time trigger all the reversible lamps under the host to enter the emergency mode to ensure the normal operation of the lighting equipment.

[0056] If the actuating device is a power supply: the system will instruct the power supply to enter emergency mode, and at the same time trigger all the reversible lamps under the power supply to enter emergency state, to ensure the continuous operation of power supply and lighting equipment.

[0057] If the actuating device is a loop: the system will instruct all lamps in the loop to enter the emergency state to ensure that the lighting functions of all lamps in the loop can operate normally in an emergency situation.

[0058] If the actuated device is a separate lamp: the system will directly instruct the lamp to enter the emergency state to provide the necessary emergency lighting.

[0059] If the actuated device is a building, floor or partition: the system will instruct all relevant power supplies, lamps and routes in the building, floor or partition to enter emergency mode to ensure that in the event of a fire or other emergency, the safe evacuation and lighting needs of the entire area can be effectively met.

[0060] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
