Description

Technical Field

[0001] This invention belongs to the field of fire accident investigation technology, and in particular relates to an auxiliary method for determining the location of a socket fire hole. Background Technology

[0002] In various electrical fire accidents, sockets and power strips are among the most common sources of fire due to their high frequency of use and large load fluctuations. Accurately determining the location of the fire hole in the socket is a crucial step in clarifying the fire's spread path and assigning responsibility for the accident.

[0003] In current fire investigation practices, determining the location of a fire originating outlet relies primarily on the investigator's personal experience. This involves visually observing the burn pattern on the outlet panel, combined with on-site statements, electrical load records, and the status of the power distribution system to make a subjective judgment. This method has significant drawbacks: it is highly subjective, with different investigators easily interpreting the same burn marks differently, leading to inconsistent results; it has poor repeatability, as the same investigator may make different judgments about the same evidence at different times, making it difficult to establish a unified standard; and it demands a high level of experience from frontline investigators, which is difficult for novices to master quickly.

[0004] From the perspective of electrical fault mechanisms, the root causes of socket fires are mostly overload, short circuit, or poor contact. The initial physical traces of the fault are first manifested on the plug, prongs, or internal metal contacts of the socket. Their erosion morphology, molten bead distribution, and arcing marks are core evidence reflecting the source of the fire. However, in actual fire scenes, these key pieces of evidence are often difficult to utilize effectively: on the one hand, during the development of a fire, the room may undergo a full development or even a flashover stage. The socket panel and surrounding walls are eroded by high-temperature flames and smoke, resulting in large-area deep carbonization, dripping, and overall blackening, which can obscure the initial fault traces and even create the illusion that the fire damage is more severe than the fault traces; on the other hand, metal contacts are easily melted, deformed, or detached at high temperatures, or lost during the subsequent cleanup of the fire, leading to the loss of key traces; in addition, grassroots fire investigation work is limited by time, manpower, and technical conditions, lacking the foundation for conducting complex experiments and precise tests, and urgently needs a simple, standardized, and easily promoted judgment method.

[0005] Currently, there is no standardized judgment system that takes into account panel appearance marks, metal contact marks, and the influence of the fire environment. This results in insufficient accuracy and reliability in determining the location of socket fire ignition points, affecting the impartiality and efficiency of fire accident investigations. Therefore, designing an auxiliary judgment method that does not require complex instruments, is simple to operate, can integrate multi-dimensional trace information, and avoids interference from the fire environment has become an urgent need for grassroots fire investigation work. Summary of the Invention

[0008] As an optional solution of the present invention, the establishment of the standard partition template in step S1 includes: taking the center of each socket as a reference, dividing the area around the socket into four near-zone ablation scoring areas: upper, lower, left, and right; dividing the panel frame and edge into edge ablation scoring areas; and using a planar diagram to record the spatial position of each area and its correspondence with the socket.

[0009] As an optional aspect of this invention, the ablation degree rating B i The degree of surface discoloration, carbonization, and material loss is scored from 0 to 3; the degree of deformation is scored as D. i The degree of bulging, collapse, and warping is scored from 0 to 3; the melt flow score is M. i The clarity and quantity of droplets, wire-like patterns, and flow marks are scored from 0 to 3 points; the overall score is S. i =a·B i +b·D i +c·M i, where a, b, and c are weighting coefficients.

[0010] As an optional solution of the present invention, in step S4, the panel fire suspicion index I oj The calculation method is as follows: I oj =ΣS i (i∈Ω) j ), where Ω j This is the set of ablation scoring regions associated with the j-th orifice.

[0011] As an optional aspect of the present invention, in step S5, the contact trace scoring C j The acquisition includes: observing and recording the erosion range, number and size of molten beads, and clarity of arcing marks of the metal contacts; and scoring them on a scale of 0 to 5 according to the degree of erosion concentration, molten bead distribution characteristics, and typicality of arcing marks to obtain a C rating. j .

[0012] As an optional aspect of the present invention, in step S5, the comprehensive fire suspicion index H j The calculation method is as follows: H j =α·I oj +β·C j Where α and β are weighting coefficients and α+β=1; when contact traces are missing, β is set to 0, and only I is used. oj As H j .

[0013] As an optional embodiment of the present invention, it further includes step S0: assessing the fire load and fire severity of the area where the socket is located, including at least the extent of smoke and charring on the ceiling and walls, deep charring and drip marks around the socket, and the types and quantities of nearby combustibles, to determine the fire severity classification; and applying an environmental correction factor E according to the classification. j Obtain the adjusted H' j The confidence levels were then categorized, with large-scale fires being the dominant scenario marked as low confidence.

[0014] As an optional solution of the present invention, the environmental correction factor E j The value ranges from 0.3 to 1.0; the more severe the overheating, the higher the value of E. j The smaller the value.

[0017] The above-mentioned technical solutions in the socket fire hole location auxiliary determination method provided in the embodiments of the present invention have at least one of the following technical effects:

[0018] 1. Standardized quantitative analysis to reduce subjective differences: By establishing panel standard partition templates and unified scoring rules, the traditional experience-based "visual observation" is transformed into a standardized partition scoring and calculation process, which greatly reduces the subjective judgment bias of different investigators and improves the consistency and repeatability of the judgment results.

[0019] 2. Multi-dimensional trace fusion to improve judgment accuracy: By comprehensively utilizing the traces on the socket panel and the core traces of the metal contact parts, a dual scoring system is constructed. This system not only retains the thermal distribution characteristics reflected by the panel traces, but also makes full use of the metal contact traces that are close to the source of the fault, making the judgment basis more comprehensive and accurate.

[0020] 3. Avoid interference from the fire scene environment and reduce the risk of misjudgment: A fire load and fire severity assessment mechanism is specially introduced. Through environmental correction coefficients and confidence level classification, the influence of "fire traces covering initial fault traces" is effectively offset, making the judgment process more in line with the fire development law and reducing the probability of misjudgment.

[0021] 4. Traceable and verifiable, suitable for judicial applications: The standardized investigation record form fully records the analysis process and all data, enabling full traceability of the judgment process, facilitating subsequent review, expert consultation, and evidence presentation in judicial proceedings, and improving the standardization of investigation work;

[0022] 5. Easy to operate and suitable for grassroots promotion: The implementation only requires photographic equipment, tape measure and paper record form. No complicated instruments and advanced calculations are required. Grassroots investigators can master it after short-term training and it can be quickly applied to a large number of daily fire investigations, significantly improving investigation efficiency.

[0023] 6. Adaptable to various socket types, highly versatile: The standard partition template can be adapted to the structural characteristics of two-hole, three-hole, multi-group combination sockets and power strips, covering the vast majority of common socket types and with a wide range of applications.

[0030] Example 1: Auxiliary determination of the fire hole position in a single set of three-hole sockets

[0031] This embodiment is directed to a single-group three-hole socket commonly used in residential houses, with a panel size of 86mm×86mm and the jacks distributed in a "pin" shape. The specific judgment steps are as follows:

[0032] S0. Fire load and fire severity assessment: After the investigators arrive at the fire scene, first observe the overall damage situation of the room where the socket is located: The smoked and carbonized range of the ceiling and walls covers the entire room. There are obvious deep carbonization and molten flow marks on the wall above the socket. There are remains of wooden furniture (completely carbonized) within 1m near the socket. It is determined that the fire load in this area is relatively high and the fire severity is "severely burned". Set the environmental correction factor E j =0.5, and the confidence level of the judgment result is "low confidence level".

[0033] S1. Establish a standard zoning template: Take the centers of the three jacks of the three-hole socket as reference points respectively, and divide four near-area ablation scoring areas (a total of 12 near-area areas) above, below, left, and right around each jack; Divide the upper, lower, left, and right four side frames of the panel into 1 edge ablation scoring area each (a total of 4 edge areas), with a total of 16 ablation scoring areas numbered 1-16 in sequence; Use a floor plan to draw the spatial positions of each area, and clarify that numbers 1-4 correspond to the upper left jack, 5-8 correspond to the upper right jack, 9-12 correspond to the lower jack, and 13-16 are edge areas and have an associated relationship with all three jacks.

[0034] S2. On-site information collection: S2-1, Use a digital camera to take multiple-angle photos of the front of the remaining socket panel to ensure that the ablation situation of each scoring area is clearly presented, and record the surface state of each area through visual observation; S2-2, Find the corresponding plug in the on-site debris. The metal inserts are not completely melted and there are some corrosion marks left. Take photos and make written records of the corrosion positions, the number of molten beads, and the arcing marks of the inserts.

[0035] S3. Appearance ablation scoring: Score the 16 areas respectively according to the preset scoring rules. The weight coefficients in the scoring rules are set as a = 0.4, b = 0.3, c = 0.3:

[0036] Area 1 (near the upper left jack): The surface is severely carbonized, with local material loss (B i =3 points), obvious collapse and deformation (D i =3 points), visible clear molten droplet flow marks (M i =3 points), and the comprehensive score S1 = 0.4×3 + 0.3×3 + 0.3×3 = 3.0 points;

[0037] Area 5 (near the upper right jack): The surface is slightly carbonized (B i =1 point), without obvious deformation (D i =0 point), without molten flow marks (Mi =0 points), the overall score S5 = 0.4 × 1 + 0.3 × 0 + 0.3 × 0 = 0.4 points;

[0038] Area 9 (near the lower socket): Moderate surface carbonization (B) i =2 points), slight bulge (D) i =1 point), a small amount of molten droplet traces (M) i =1 point), the overall score S9 = 0.4×2 + 0.3×1 + 0.3×1 = 1.4 points;

[0039] Edge regions 13-16: Moderate surface carbonization (B i =2 points), slight warping (D) i =1 point), no obvious traces of melting and flow (M) i =0 points), the comprehensive score for each edge region is S=0.4×2+0.3×1+0.3×0=1.1 points;

[0040] The remaining areas are scored using the same rules, resulting in a combined score S for all 16 areas. i .

[0041] S4, Calculate the fire suspicion index of the panel. oj Based on the relationship between the region and the socket, calculate the I of each of the three sockets. oj :

[0042] Top left jack (j=1): Associated regions are 1-4 and 13-16, I o1 =S1+S2+S3+S4+S 13 +S 14 +S 15 +S 16 =3.0+2.8+2.9+2.7+1.1+1.1+1.1+1.1=15.8 points;

[0043] Top right jack (j=2): Associated areas are 5-8 and 13-16, I o2 =S5+S6+S7+S8+S 13 +S 14 +S 15 +S 16 =0.4+0.5+0.3+0.6+1.1+1.1+1.1+1.1=5.1 points;

[0044] The lower socket (j=3): the associated areas are 9-12 and 13-16, I o3 =S9+S 10 +S 11 +S 12 +S 13 +S 14 +S15 +S 16 =1.4+1.2+1.3+1.5+1.1+1.1+1.1+1.1=9.8 points.

[0045] S5. Contact Trace Score and Comprehensive Fire Suspicion Index Calculation: Observe the collected plug metal prongs. The prong corresponding to the upper left socket has a large erosion range, many molten beads (3 beads, 0.8-1.2mm in diameter), and clear arcing marks, with a contact trace score of C1=5 points; the prong corresponding to the upper right socket has slight erosion, no obvious molten beads, and blurry arcing marks, with a C2=1 point; the prong corresponding to the lower socket has moderate erosion, 1 molten bead, and relatively clear arcing marks. Clearly defined, C3 = 3 points; setting weighting coefficients α = 0.6 and β = 0.4 (α + β = 1), the comprehensive fire suspicion index is calculated as follows: H1 = 0.6 × 15.8 + 0.4 × 5 = 9.48 + 2.0 = 11.48 points; H2 = 0.6 × 5.1 + 0.4 × 1 = 3.06 + 0.4 = 3.46 points; H3 = 0.6 × 9.8 + 0.4 × 3 = 5.88 + 1.2 = 7.08 points; combined with the environmental correction coefficient E j =0.5, calculate the adjusted comprehensive fire suspicion index: H'1=0.5×11.48=5.74 points; H'2=0.5×3.46=1.73 points; H'3=0.5×7.08=3.54 points.

[0046] S6. Determination of fire ignition hole location: For H' j The holes were sorted, H'1 > H'3 > H'2, and the upper left hole was identified as a suspected first-level fire ignition hole. Because the area was severely burned, the result was marked as low confidence.

[0047] S7. Auxiliary Conclusion Output: Reviewing the power distribution record for this circuit reveals that the circuit breaker did not trip during the fire. Combined with the power load data, the power of the device connected to the upper left socket was 1500W (within the normal load range); (H') j Based on the circuit breaker's failure to trip and the electrical load conditions, the auxiliary conclusion is that the upper left socket of the three-hole socket is the most likely location for the fire. It is recommended to further analyze the situation by combining the cross-sectional shape of the conductors and other physical evidence at the scene.

Generate a standardized record sheet: This sheet includes a panel layout diagram of the three-hole socket and scores for each of the 16 areas (B). i D i M i S i ), three sockets I oj C j H j H' jThe environmental correction factor, confidence level, and final auxiliary judgment conclusion should be uniformly filled in the "Electrical Fire Socket Ignition Hole Location Investigation Record Form," signed, and filed for future review.

[0049] Example 2: Auxiliary determination of fire ignition hole location in multiple sets of combination sockets (2 sets of two-hole sockets + 1 set of three-hole sockets)

[0050] S0. Fire Load and Fire Severity Assessment: The office space where the socket is located experienced only localized fire damage. The smoke on the ceiling and walls was limited to within 0.5m of the socket, with no obvious dripping marks. There were no flammable or combustible materials nearby. The fire severity is determined to be "minor fire damage," with an environmental correction factor E. j =0.9, confidence level is "high confidence".

[0051] S1. Establish a standard zoning template: Divide the near zone according to the center of each socket (each socket corresponds to 4 near zones), and divide the edge zone (4) according to the panel frame. A total of 2 groups of two-hole sockets × 4 + 1 group of three-hole sockets × 4 + 4 edge zones = 24 ablation scoring areas. Clarify the relationship between each area and 5 sockets (2 groups of two-hole sockets are sockets 1-2, and three-hole sockets are sockets 3-5).

[0052] S2. On-site information collection: The panel was photographed and visually observed. No complete plug or metal contact parts were found (contact traces were missing).

[0053] S3. Appearance Ablation Scoring: 24 areas are scored according to the rules, with weighting coefficients a=0.5, b=0.3, and c=0.2. The overall score S for each area is calculated. i .

[0055] S5. Calculation of Comprehensive Fire Suspicion Index: Due to missing contact traces, β=0, H j =I oj After adjustment H' j =0.9×I oj H'2 of socket 2 is 16.74 points.

[0056] S6. Ignition hole location determination: H' of socket 2 j If the maximum value exceeds the preset threshold (10 points), it is designated as a Level 1 suspected hole location with a high confidence level.

[0057] S7. Auxiliary conclusion output: The circuit breaker tripped during the fire. The device connected to socket 2 was a printer (300W). Based on the overall assessment, socket 2 is the socket with the highest suspicion of fire.

[0058] S8. Generate standardized record forms: Fill out the survey record forms completely as required and archive them.

[0059] It should be noted that the analysis results of this invention are only used as an auxiliary basis for determining the location of electrical fire ignition holes. In practical applications, they should be comprehensively evaluated in conjunction with conductor cross-sectional morphology, protection device operation records, electrical load data, other physical evidence at the scene, and expert opinions. They should not be used as the sole evidence.
