[0009] Preferably, the fence lengths and the safety warning indexes of the four fences are all calculated and outputted synchronously at the same time, and then the fence lengths and the safety warning indexes of the four fences are averaged, specifically as follows: First, the measured lengths of the first fence WL1, the second fence WL2, the third fence WL3 and the fourth fence WL4 are calculated using WL avg =(WL1+WL2+WL3+WL4) / 4 calculation formula is used to calculate and output the average length to obtain the average length feature of the fence; Secondly, based on the length and height corresponding to the same side and the safety mark quantity QB, obtain the first side safety warning index, the second side safety warning index, the third side safety warning index, and the fourth side safety warning index of the four sides of the fence; Then, using WJ avg =(WJ1+WJ2+WJ3+WJ4) / 4 is used to calculate and output the average safety warning index of the four fences.

When the comprehensive effect evaluation value decreases, it means that the safety warning effect of the fence has decreased, and measures need to be taken to adjust it. Then, according to the fence safety warning indexes on the four sides, the fence surface corresponding to the lowest safety warning index is given priority maintenance, and this circular feedback mechanism ensures the continuous improvement and optimization of the fence safety warning effect.
[0019] Compared to existing technologies, this method not only improves the accuracy and efficiency of assessments, but also, through the introduction of an algorithmic formula and a loop feedback mechanism, dynamically adjusts and optimizes the effectiveness of fence safety warnings. This innovative approach not only addresses the shortcomings of traditional methods but also provides new insights and methods for construction project management. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments.
[0022] Reference Figure 1-4 As shown, the present invention provides a technical solution: a construction project management safety warning method, including a data acquisition module, a warning effect evaluation module and a maintenance and adjustment module, characterized in that the warning effect evaluation module includes a preliminary safety warning effect evaluation unit, a dynamic safety warning effect improvement unit and a safety warning comprehensive evaluation unit. The specific steps are as follows: Step 1: The data collection module is used to regularly collect the length, height, number of safety signs, area of the surrounding area, degree of damage, and density of people of the fence in the current period and summarize them into fence management features; Step 2: Transmit the fence management features to the warning effect evaluation module; Step 3: The warning effect evaluation module obtains the safety warning index, safety warning adjustment coefficient, and comprehensive effect evaluation value based on the fence management characteristics; Step 4: The maintenance and adjustment module receives the comprehensive effect evaluation value and obtains the historical evaluation features including the previous comprehensive effect evaluation value from the data acquisition module; Compare and analyze the previous comprehensive effect evaluation value with the comprehensive effect evaluation value, and output adjustments to the safety warning strategy based on the analysis results; Among them, if the four sides of the fence are of equal length and regular, choose any one of them; If the four fences are of different lengths and irregular, choose the side with the most obvious irregular features.
[0023] Through detailed descriptions of the overall method steps, modules and units, and the equipment used, this embodiment can construct a complete construction project management safety warning method system, achieve regular evaluation and maintenance of the fence safety warning effect, and thus ensure the safe operation of the construction project.
[0024] Reference Figure 2-4 As shown, in this embodiment: the preliminary safety warning effect evaluation unit obtains the actual warning characteristics according to the fence length and the number of safety signs in the fence management characteristics; Obtain visual warning features based on fence height and enclosed area; According to the damage degree of the fence in the current cycle, obtain the damage degree coefficient with a value range of {0-1}; Obtain a safety warning index based on actual warning characteristics, visual warning characteristics, and damage degree coefficient; The calculation formula for the preliminary evaluation of the safety warning effect unit is as follows: ; in: WJ is the safety warning index; WL is the fence length, WL represents the length of one of the four fences; QB is the number of safety signs, which means the number of safety signs installed on one of the four fences; WH is the fence height, which means the height of one of the four fences; WM is the enclosed area, WM represents the total area of the area surrounded by the four fences; SH is the damage degree coefficient, and the value range of SH is {0-1}, 0 means no damage, and 1 means complete damage; Reflects the "visibility" and "presence" of the fence. Specifically, the higher the height and the smaller the area, the more significant the warning effect of the fence. The square root processing takes into account the nonlinear relationship between area and height.
[0025] In this unit algorithm The calculation part is used to evaluate the combined impact of the fence length WL and the number of safety signs QB. The longer the fence length WL, the larger the protection area that needs to be covered. Therefore, more safety signs are needed to ensure the warning effect. Multiplying the fence length WL by the number of safety signs QB can quantify this combined impact. This calculation part, as an important part of the calculation of the safety warning index WJ, reflects the basic safety warning capability of the fence.
[0026] The calculation part is used to evaluate the impact of the proportional relationship between the fence height WH and the area of the area it surrounds on the safety warning effect. The proportional relationship between the fence height WH and the area A it surrounds is that when the fence height WH increases, its visual "visibility" and "presence" will also increase accordingly, which means that people are more likely to notice the existence of the fence, thereby playing a more effective warning role. At the same time, if the area WM surrounded by the fence is small, then the height of the fence relative to the area will be more prominent, further enhancing its warning effect.
[0027] The negative impact of the degree of damage to the fence on the safety warning effect is taken into account, and the higher the damage coefficient SH of the fence, the worse its safety warning effect. Therefore, subtracting the damage coefficient SH in the calculation of the safety warning index WJ can reflect this negative impact.
[0028] In this algorithm unit, the two parameters of fence length WL and fence height WH directly reflect the physical dimensions of the fence. They are the basis for evaluating whether the fence can effectively isolate dangerous areas and prevent people from accidentally entering. By quantifying these two parameters, the protective capabilities of the fence can be more accurately judged.
[0029] Safety signs are an important means of reminding people to pay attention to safety and comply with regulations. By increasing the number of safety signs QB, the safety warning effect of the fence can be significantly improved. The preliminary evaluation of the safety warning effect unit uses the number of safety signs as an important indicator to evaluate the safety warning effect of the fence, which helps to guide attention to the improvement of signs in the setting of fences.
[0030] In addition, the preliminary safety warning effect assessment unit takes into account the area, making the safety warning effect assessment of the fence more realistic. Then, by introducing the damage degree coefficient SH, the preliminary safety warning effect assessment unit can accurately reflect the current status of the fence, providing strong support for timely maintenance and repair. In summary, the preliminary safety warning effect evaluation unit provides a comprehensive and quantitative evaluation standard for the safety warning effect of the fence by comprehensively considering the above parameters, which helps to intuitively understand the safety status of the fence and guide subsequent maintenance and optimization work.
[0031] Reference Figure 2-4 As shown, in this embodiment: the fence length WL and the safety warning index WJ of the four fences need to be synchronously calculated and output at the same time, and then the fence length WL and the safety warning index WJ of the four fences are averaged, as follows: First, the measured lengths of the first fence WL1, the second fence WL2, the third fence WL3 and the fourth fence WL4 are calculated using WL avg =(WL1+WL2+WL3+WL4) / 4 calculation formula is used to calculate and output the average length; Secondly, according to the length, height and safety mark quantity QB corresponding to the same side, enter In the calculation formula, the safety warning index WJ of the four fences is output in sequence; Then, using WJ avg =(WJ1+WJ2+WJ3+WJ4) / 4 calculation formula is used to calculate and output the average safety warning; Among them, WL avg is the average length of the fence, WJ avg is the average safety warning index, WJ1 is the average safety warning index of the first fence, WJ2 is the average safety warning index of the second fence, WJ3 is the average safety warning index of the third fence, and WJ4 is the average safety warning index of the fourth fence.
[0032] In this embodiment, averaging the fence lengths WL and safety warning indexes WJ of the four fences helps to comprehensively evaluate the fence as a whole and to subsequently dynamically improve the comparative evaluation of the averaging calculations of the safety warning action unit and the safety warning comprehensive evaluation unit.
[0033] Reference Figure 2-4 As shown, in this embodiment: the dynamic safety warning function improving unit obtains the adjusted safety warning feature according to the safety warning index, the average length feature of the fence, and the fence length; Obtain the population density adjustment feature based on population density and fence height; Obtain a safety warning adjustment coefficient based on the adjusted safety warning characteristics and personnel density adjustment characteristics; The calculation formula for dynamically improving the safety warning function unit is as follows: ; RM=RL / WM; in: AT is the safety warning adjustment coefficient, which is used to adjust the safety warning effect of the fence according to the density of people; RM is the population density; RL is the average flow rate; Reflects the safety warning capability of one of the four fences relative to the other fences. If the result value is not equal to 1, it means that the length of the current fence is different from the length of other fences, thereby quantifying the fence length WL and the average fence length WL avg differences; The higher the middle RM, the more likely the warning effect of the fence will be blocked and ignored.
[0034] In this unit algorithm The calculation section evaluates the proportional relationship between the current fence's safety warning index WJ and its length relative to the average length. Specifically, the proportional relationship between the current fence's safety warning index WJ and its length relative to the average length of all fences in the same area is calculated. This reflects the fence's safety warning capability relative to other fences. Multiplying this proportional relationship adjusts the safety warning adjustment coefficient AT to account for differences in fence length. This provides an important adjustment factor for the safety warning adjustment coefficient AT, helping to more accurately assess the safety warning effectiveness of fences in crowded environments.
[0035] In the calculation part, the higher the population density RM, the more likely the fence's warning effect is to be blocked and ignored. Therefore, dividing the fence height WH by the square root of the population density RM can quantify this negative impact and subtract this value from the safety warning adjustment coefficient AT. This part also introduces a population density adjustment factor to enable the safety warning adjustment coefficient AT to more accurately reflect the actual safety warning effect of the fence in a densely populated environment.
[0036] In this algorithm unit, the higher the population density, the greater the safety warning responsibility of the fence. The dynamic improvement of the safety warning effect unit takes the population density into consideration, so that the safety warning effect of the fence can be flexibly adjusted according to different scenarios, which is more in line with the actual situation.
[0037] The safety warning adjustment coefficient AT in the dynamic improvement of safety warning effect unit is adjusted based on the safety warning index WJ calculated by the preliminary evaluation of safety warning effect unit. This synergistic effect makes the safety warning effect evaluation of the fence more comprehensive and accurate, taking into account both the physical size and status of the fence itself and the dynamic factor of personnel density.
[0038] Reference Figure 2-4 As shown, in this embodiment: the safety warning comprehensive evaluation unit obtains the safety effect feature according to the safety warning average index, the repair rate, the damage degree coefficient, and the maximum damage degree coefficient in the historical evaluation feature; Obtain the safety-affecting features based on the safety warning index, safety warning adjustment coefficient, and the maximum safety warning adjustment coefficient in the historical assessment features; Subtract the safety-affecting feature from the safety-effect feature to obtain a comprehensive effect evaluation value; The calculation formula for the safety warning comprehensive evaluation unit is as follows: ; in: is value; AX is the comprehensive effect evaluation value; F is the repair rate, and the value range of F is {0-1}, 1 means complete repair, and 0 means no repair; SH max is the maximum damage coefficient, and its value is 1; AT max It is the maximum adjustment factor for safety warning; It reflects the comprehensive effect of the fence's overall safety warning capability and repair rate F, and WJ avg Reflects the overall safety warning capabilities of the four-sided fence, The square root processing is performed to quantify the nonlinear effect of F on the safety warning effect. The higher F is, the more efficient the fence damage is in being repaired in time. Reflects the degree of gap between the current security warning capability of one of the four fences and its potential maximum security warning capability.
[0039] In this unit algorithm The calculation part is used to evaluate the comprehensive impact of the average safety warning index WJ of all fences in the same area and the fence repair rate F, among which the average safety warning index WJ of the fence is avgIt reflects the overall safety warning capability of the fences in the area. The higher the fence repair rate F, the more likely it is that the fence damage will be repaired in a timely manner, which helps to improve the safety warning effect. The square root of the repair rate is taken and multiplied by an adjustment factor related to the proportional relationship between the current damage level and the maximum value. This combined impact can be quantified, thereby reflecting the combined effect of the overall safety warning capability of the fences in the area and the repair rate F.
[0040] The calculation part considers the negative impact of the current fence's safety warning index WJ and the proportional relationship between its adjustment coefficient and the maximum adjustment coefficient on the comprehensive effect evaluation value AX; Among them, the current fence's safety warning index WJ and its safety warning adjustment coefficient AT relative to the maximum safety warning adjustment coefficient AT max The proportional relationship can reflect the gap between the fence and its potential maximum safety warning capability. Multiplying the proportional relationship of this gap and subtracting this value from the comprehensive effect evaluation value AX can reflect this negative impact, so that the comprehensive effect evaluation value AX can more accurately reflect the actual safety warning effect of the fence in a comprehensive environment and provide guidance for further adjustment and optimization.
[0041] By comprehensively considering multiple factors, this algorithm unit enables the safety warning comprehensive evaluation unit to more accurately reflect the safety warning effect of the fence, thereby providing a more comprehensive and reliable evaluation result. The calculation results of the safety warning comprehensive evaluation unit not only reflect the safety warning effect of the fence, but also guide specific maintenance measures. The calculation results of the safety warning comprehensive evaluation unit can be used as the benchmark value for the next evaluation, forming a closed-loop feedback system. By constantly comparing and analyzing the changing trends of the comprehensive effect evaluation value AX, the safety warning effect of the fence can be continuously optimized to ensure the safety of the construction site. To sum up, the preliminary evaluation of the safety warning effect unit, the dynamic improvement of the safety warning effect unit, and the safety warning comprehensive evaluation unit and their parameters together constitute a scientific, comprehensive and dynamic fence safety warning effect evaluation system. This system not only helps to intuitively understand the safety status of the fence, but also can guide specific maintenance and optimization work, providing strong protection for the safety of the construction site.
[0042] Reference Figure 2-4 As shown, in this embodiment: based on the comprehensive effect evaluation value AX and the previous comprehensive effect evaluation value AX prev The comparative analysis and warning adjustments are as follows: If the comprehensive effect evaluation value AX is higher than the previous comprehensive effect evaluation value AX prev, it reflects that the safety warning effect of the fence has improved during this period, and the current safety warning strategy should be maintained; If the comprehensive effect evaluation value AX is lower than the previous comprehensive effect evaluation value AX prev , it reflects that the safety warning effect of the fence has declined during the period, so the safety sign quantity QB should be increased and damage repair should be carried out; The comprehensive effect evaluation value AX is higher / lower than the previous comprehensive effect evaluation value AX prev , all damages must be repaired in a timely manner, and when the comprehensive effect evaluation value AX is lower than the previous comprehensive effect evaluation value AX prev In this case, the safety warning strategy of increasing the safety sign quantity QB shall be implemented based on the size of the safety warning average index WJ1 of the first fence, the safety warning average index WJ2 of the second fence, the safety warning average index WJ3 of the third fence, and the safety warning average index WJ4 of the fourth fence, and the fence with the smallest value shall be prioritized.
[0043] This embodiment performs a preliminary evaluation of the safety warning effect unit, dynamically improves the comprehensive calculation of the safety warning action unit, and the safety warning comprehensive evaluation unit, and can obtain a comprehensive effect evaluation value AX and a safety warning index WJ for each of the four fences. These values can accurately reflect the safety status of the fence. Once the comprehensive effect evaluation value AX decreases or the safety warning index WJ of a fence is low, it means that there is a safety hazard and immediate maintenance is required. This precise positioning capability facilitates rapid response and timely elimination of safety hazards. The loop feedback mechanism allows the fence maintenance strategy to be dynamically adjusted according to the changes in the comprehensive effect evaluation value AX and the safety warning index WJ. Specifically: When the comprehensive effect evaluation value AX is higher than the previous one, it means that the safety warning effect of the fence has been improved, so the current maintenance and management strategy can be maintained; When the comprehensive effect evaluation value AX is lower than the previous one, it is necessary to take immediate measures to make corrections, including increasing the number of safety signs QB, repairing damaged fence parts, and increasing the repair rate F; This dynamic adjustment capability helps ensure that the fence always remains in good working condition, thereby effectively serving as a safety warning.
[0044] Through the circular feedback mechanism, resource allocation can also be optimized. Specifically, when increasing the number of safety signs QB, it can be reasonably set according to the actual situation and safety needs of the fence, ensuring both the improvement of the warning effect and the avoidance of excessive cost waste. At the same time, fences with a lower safety warning index WJ can be given priority for maintenance to maximize the overall safety warning effect of the fence. This ability to optimize resource allocation helps to improve maintenance efficiency and reduce costs.
[0045] The implementation of a circular feedback mechanism can also help improve the safety management level of construction project management. Through regular evaluation and maintenance, dynamic adjustment of maintenance strategies, and optimization of resource allocation measures, the safety warning system of the fence can be continuously improved, and the safety and reliability of the fence can be improved. This ability to continuously improve can help build a safer and more reliable construction project management environment and ensure the safety of personnel and property.
[0046] To sum up, the beneficial effects of the circular feedback combined with the preliminary evaluation of the safety warning effect unit, the dynamic improvement of the safety warning function unit and the safety warning comprehensive evaluation unit are mainly reflected in the precise positioning of safety hazards, dynamic adjustment of maintenance strategies, optimization of resource allocation and improvement of safety management levels. This circular feedback mechanism helps to ensure that the safety warning effect of the fence is always maintained at a high level, providing a strong safety guarantee for construction project management.
[0047] Reference Figure 1-4 As shown, in this embodiment: the equipment used in the warning effect evaluation module includes a computer and an intelligent computing device, which is used to run the preliminary evaluation of the safety warning effect unit, the dynamic improvement of the safety warning effect unit, and the operation and calculation of the calculation formula of the safety warning comprehensive evaluation unit; The equipment used in the data acquisition module includes measuring equipment, sensors and data loggers; The equipment used in the maintenance and adjustment module includes data analysis and maintenance plan formulation equipment, and display screens.
[0048] To better understand the present invention, the specific implementation process is given below: Through the data acquisition module, the fence length WL, safety mark quantity QB, fence height WH and damage degree coefficient SH of each of the four sides, as well as the enclosed area WM, personnel density RM and repair rate F are collected; Then, the preliminary safety warning effect evaluation unit can generate a numerical fence safety warning index WJ by comprehensively considering the five key factors of fence length WL, safety sign quantity QB, fence height WH, damage degree coefficient SH, and enclosed area WM. This index can intuitively reflect the safety warning capability of the fence in its current state. The higher the value, the better the warning effect of the fence.
[0049] Subsequently, the dynamic safety warning enhancement unit takes into account the population density to calculate and output the safety warning adjustment coefficient AT. The higher the population density, the greater the safety warning responsibility assumed by the fence. Therefore, the dynamic safety warning enhancement unit closely links the safety warning effect of the fence with the population density by introducing the safety warning adjustment coefficient AT. In this way, the safety warning strategy of the fence can be flexibly adjusted according to the population density in different areas, ensuring that the fence can play the greatest safety warning role under any circumstances.
[0050] Finally, the safety warning comprehensive evaluation unit conducts a comprehensive evaluation of the comprehensive safety warning effect of the fence, and based on this, uses the maintenance and adjustment module to guide further adjustment measures.
[0051] It should be noted that any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present invention should also be within the scope of protection of the present invention.
