Description

Technical Field

[0001] This invention belongs to the field of fire safety technology, and relates to building fire safety assessment technology, specifically to a building fire safety assessment system. Background Technology

[0002] With the increasing number of urban buildings, the risk of fire and fire hazards in urban buildings remain high. Once a fire occurs, it can cause irreparable losses, imposing a heavy economic and psychological burden on those affected. Therefore, regular fire safety assessments of all types of buildings are imperative. A fire safety assessment refers to the analysis and evaluation of the fire safety status of buildings, structures, activity areas, and other objects subject to fire safety regulations. It is a process of comprehensively measuring the potential unsafe factors and their possible consequences. Based on the assessment results, it is a service activity that proposes solutions in accordance with fire safety laws, regulations, and technical standards.

[0003] Conventional fire safety assessments are primarily conducted manually. Assessors use assessment forms and conduct on-site inspections to score each building parameter and fire safety equipment parameter listed in the forms. This method is extremely labor-intensive, especially for large buildings, and is very time-consuming and labor-intensive; it is difficult for one person to complete the assessment in a day. Furthermore, because it relies on on-site data collection, the data obtained is static at that moment and cannot fully reflect the building's inherent risk resistance capabilities. Summary of the Invention

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figures 1-4 As shown, the specific embodiments provided by the present invention are as follows:

[0044] Example 1:

[0045] like Figures 1-2 As shown, a building fire safety assessment system is characterized by comprising a user input module, a storage module, an external interface module, a processing module, and a display module;

[0046] The user input module is used to receive the building name entered by the user;

[0047] The storage module stores building models and building operation and maintenance information. The building models include building layout information and building fire protection equipment layout information.

[0048] The external interface module connects to external IoT fire protection equipment and receives operational data transmitted by the external IoT fire protection equipment.

[0049] The processing module includes a data extraction unit and a calculation unit;

[0050] The data extraction unit is used to extract the corresponding building model and building operation and maintenance information from the storage unit based on the building name input by the user, and to extract the building layout information and building fire protection equipment layout information from the building model.

[0051] The computing unit assesses the fire safety of the building based on the extracted building operation and maintenance information, building layout information, building fire protection equipment layout information, and the operation data transmitted from the external IoT fire protection equipment, using a preset evaluation model.

[0052] The display module is used to show the results of building safety assessments. Generally, buildings have design drawings, construction drawings, and fire protection equipment installation drawings, such as the locations of fire doors and fire extinguishers. Therefore, based on these drawings, a 3D building model can be constructed and stored in the storage module. When a building safety assessment is needed, the building layout information and fire protection equipment layout information can be directly extracted from this 3D building model. The building layout information includes the building's floor height, total number of floors, number of underground floors, fire separation distance, total area, single-floor area, fire escape route locations, number of fire escape routes, and fire escape route width. The fire protection equipment layout includes the installation locations and quantities of fire extinguishers, fire doors, emergency lights, and fire hydrants.

[0053] Many existing buildings have integrated IoT-based fire protection equipment to establish smart fire protection systems. Buildings with smart fire protection systems have a higher risk resistance capability than those without. IoT-based fire protection equipment can transmit its operational status information to a safety assessment system in real time. Based on the received IoT data, the safety assessment system can analyze the equipment's operational status, such as failure rate and replacement frequency. If the probability of failure for a piece of operating fire protection equipment is high, even if the equipment appears to be operating normally at the time of assessment, its corresponding safety factor is also low. Therefore, incorporating IoT-based fire protection equipment data into the safety assessment improves accuracy. This IoT-based fire protection equipment includes, but is not limited to, fire detectors, automatic sprinkler systems, fire pumps, and gas extinguishing cylinders. The fire protection data collected by the IoT mainly includes data from fire alarm systems, fire door monitoring systems, electrical fire monitoring systems, residual pressure monitoring systems, and combustible gas alarm systems.

[0054] In addition, the operation and maintenance of a building also significantly impacts its resilience. For a building's fire safety assessment, besides the building's parameters and the compliance of its fire equipment, even if the building currently meets relevant laws and regulations, a lack of maintenance and management over a long period can create significant safety hazards. The building's fire safety management and operation are closely related to the fire safety assessment. For example, the safety coefficient differs between inspections every 10 days and every 5 days, and between quality inspections every six months and every year. Different operation and maintenance models result in different probabilities and timeliness of hazard detection. Therefore, the fire management and operation and maintenance model (i.e., operation and maintenance data) must also be input into the fire safety assessment model. Building operation and maintenance parameters include, but are not limited to: whether a mini fire station is equipped, whether a volunteer fire brigade has been established, whether regular maintenance has been conducted, the qualifications of the maintenance unit, the timeliness of maintenance, the quality of maintenance, the timeliness of repairs, fire management systems, whether fire drills have been conducted, and whether fire duty personnel are certified. Some building operation and maintenance parameters can be directly entered, while others can be extracted from inspection task lists received from the system.

[0055] This embodiment comprehensively assesses fire safety by integrating fire protection data and operation and maintenance data collected from buildings and the Internet of Things. The fire safety assessment model outputs fire safety assessment results and rectification suggestions, which can provide fire safety management personnel with directions for improvement and promote the improvement of the building's fire safety index.

[0056] Existing building fire safety assessments rely on manual data collection, summarizing the data before evaluating the fire safety index. This method is labor-intensive and inefficient, as each assessment depends on manual data collection and is static, making real-time and dynamic assessments difficult. With time and environmental changes, staff cannot collect data continuously, and changes in the fire safety index are not reflected in real time. Low fire safety indices or precarious fire safety conditions are often undetected, posing significant safety hazards. Therefore, this invention proposes a building fire safety assessment system. This system, through a computing unit, uses extracted building operation and maintenance information, building layout information, building fire equipment layout information, and operational data transmitted from external IoT fire equipment. It employs a pre-set assessment model to evaluate the building's fire safety, providing real-time results. This invention allows for online monitoring, significantly reducing the building's risk factor.

[0057] Example 2:

[0058] The processing module also has an element extraction unit. The operation and maintenance input unit can be used to receive the inspection task list. The element extraction unit is used to extract the number of inspectors, the qualification status of the inspectors, and the inspection frequency of different types of fire protection data from the inspection task list.

[0059] Fire safety inspections of most buildings are highly flexible, leading to significant fluctuations in data such as the number of inspectors, inspection frequency, inspector qualifications, quality inspection cycle of fire equipment, fire equipment replacement cycle, and compliance of IoT system settings. This makes it difficult to obtain accurate data, resulting in inaccurate operation and maintenance data and reducing the reliability of fire safety assessments.

[0060] In this embodiment, since the operation and maintenance input unit has difficulty obtaining operation and maintenance data, the task list for each inspection is input into the operation and maintenance input unit. The element extraction unit is used to extract the number of inspectors, the qualification status of the inspectors, and the inspection frequency of different types of fire protection data from the task list. This invention can improve the accuracy of operation and maintenance data and ensure the accurate evaluation of the fire safety scoring model.

[0061] Example 3:

[0062] For newly constructed buildings, building drawings are readily available, and building models can be built directly. However, there are still a large number of older buildings that require fire safety assessments. Due to the passage of time and changes in management personnel, design drawings and other data for older buildings have been lost, making it very difficult to establish a fire safety assessment system for older buildings.

[0063] Therefore, in this embodiment, as Figures 3-4 As shown, it also includes a modeling module; the modeling module includes a prefabricated model unit, a guidance unit, and a model generation unit; the prefabricated model unit stores N prefabricated models; the user input module is also used to receive the prefabricated model selected by the user and input model information according to the guidance information generated by the guidance unit; the guidance unit is used to generate guidance information according to the prefabricated model selected by the user; the model generation unit is used to generate a model according to the selected prefabricated model and the input information.

[0064] The modeling module also includes a prediction unit, which is used to predict the building layout and the layout of the building's fire protection facilities based on the prefabricated model selected by the user, the partially entered model information, and the preset prediction model.

[0065] The visualization display unit is used to visualize the predicted building layout and the layout of the building's fire protection facilities.

[0066] When modeling an older building, the user first selects one of N prefabricated models stored in the prefabricated model unit that most closely resembles the structure of the building. For example, if the building is a tower structure, the corresponding tower prefabricated model is selected. After selecting the model, the system generates guidance information, leading the user step-by-step to input information such as the building type, total number of floors, number of underground floors, total building length, and total building width—easily obtainable parameters. Then, based on the user-input parameters, the selected prefabricated model, and a preset prediction model, the system predicts the building layout and the layout of its fire protection facilities. Because buildings of the same type meet the same fire safety standards, and developers tend to use similar layouts for fire protection equipment, predictions can be made based on the building type and known parameters to determine the building layout and the layout of its fire protection facilities.

[0067] The building layout includes, but is not limited to, the layout of each floor's corridors, rooms, fire exits, etc.; the building's fire protection facilities layout includes, but is not limited to, the locations of fire hydrants, fire extinguishers, and fire doors. The predicted building layout and the building's fire protection facilities layout will be highlighted or flashed in the building's 3D model.

[0068] In addition, the system includes a list generation unit, which generates a list to be confirmed based on the predicted building layout and fire protection facility layout. This is because the predicted building layout and fire protection facility layout are not precise and require verification.

[0069] It also includes a task dispatch unit, which generates tasks to be confirmed based on the list of items to be confirmed. The dispatch methods include, but are not limited to, generating tasks based on the type of fire-fighting equipment or building layout to be confirmed, or based on the location of the fire-fighting equipment or building layout to be confirmed, and then dispatching these tasks to the inspection personnel. For example, tasks can be divided according to the area to be confirmed; all fire-fighting equipment and building parameters to be confirmed in area A can be assigned as a single task to one person, improving the inspection efficiency of the personnel and eliminating the need for them to travel back and forth. Alternatively, tasks can be divided according to the type of equipment to be confirmed, such as assigning the inspection of all fire extinguishers as a single task. The purpose of this is that different inspectors have varying levels of familiarity with the equipment, leading to higher accuracy and efficiency in inspecting specific types of fire-fighting equipment.

[0070] In this embodiment, when collecting building information, if conventional direct on-site detection methods are used, it requires a professional with certain fire protection knowledge to conduct the inspection, as they are more likely to know where fire protection equipment is located, thus reducing the chance of missing any detections. However, in this embodiment, because a preset model predicts and visualizes the building layout and fire protection facility layout based on a selected preset base model and some input building parameters, the inspection personnel can hold a terminal in one hand while looking at the visualized 3D model during the inspection. This guides the inspection personnel to be more targeted in their confirmation, reduces the chance of missing any detections, and can be operated by general personnel.

[0071] In addition, when confirming the layout of buildings and their fire protection facilities, tasks should be assigned to allow multiple people to confirm simultaneously, thus increasing efficiency. Task assignment can also be conducted through a combination of order placement and paid order acceptance. This allows security personnel to perform the confirmation work incidentally while conducting building patrols.

[0072] Example 4

[0073] The evaluation system also includes a positioning module, which is used to acquire the location information of the inspectors and display the location information synchronously in the three-dimensional visualization model of the building; and a confirmation module, which is used to allow the inspectors to input confirmation information when the location information of the inspectors located by the positioning module is the same as the location information of the equipment to be confirmed. The confirmation information includes "yes" or "no".

[0074] In this embodiment, the inspector holds a handheld positioning module, which can be a GPS positioning module built into the mobile phone or other modules with positioning functions. When displaying the 3D model of the building, the display module also synchronously displays the inspector's position within the building. Specifically, when the user's walking position within the building changes, such as moving from area A to area B, a corresponding marker in the 3D model changes from area A to area B. This setup aims to ensure that the inspector always clearly knows their location within the building and their distance from the fire-fighting equipment to be inspected. This feature is particularly important for large buildings, improving the inspector's efficiency and preventing them from getting lost.

[0075] When the inspector arrives at the predicted inspection location, that is, when the location information of the inspector located by the positioning module matches the location information of the device to be inspected, the inspector inputs the confirmation information "Yes" or "No". When the inspector inputs "No", the system will recommend another inspection location and display guidance to the inspector to conduct further inspection.

[0076] In this embodiment, there is also a new addition unit, which is used to input the type and model of the fire-fighting equipment when the inspector detects fire-fighting equipment that is not on the list to be confirmed; and a visualization display unit, which synchronously displays the newly added fire-fighting equipment at the location of the inspector in the three-dimensional model.

[0077] Once all the pending confirmations have been confirmed, a building model will be generated based on the confirmed and newly added information and saved to the storage module.

[0078] In addition, if the assessment results of the building's fire safety are not up to standard, recommendations are generated, including improving operation, adding new fire-fighting equipment, and establishing an intelligent fire protection system.
