Description

Technical Field

[0001] The present invention relates to the technical field of infrastructure construction, and in particular to an infrastructure construction site safety management system. Background Art

[0002] In the rapidly developing modern society, infrastructure construction is an important means to promote economic growth and improve people's livelihood. However, infrastructure projects often have the characteristics of large investment, long cycle, complex technology and high labor intensity. Construction site safety management has become a key factor in ensuring project quality and construction efficiency. Safety management of infrastructure construction sites can not only protect the lives of workers, but also effectively reduce economic losses and enhance corporate image. Therefore, it is extremely necessary to carry out safety management of infrastructure construction sites.

[0003] Prior art, such as the invention application patent with announcement number: CN116934099A discloses a safety management system for infrastructure construction sites. The invention includes a safety management platform, which is connected to a site traffic safety monitoring unit, a traffic environment analysis monitoring unit, a construction equipment analysis monitoring unit, and an equipment operation safety risk unit. The site traffic safety monitoring unit performs traffic safety monitoring on the infrastructure construction site and monitors traffic around the construction area in the infrastructure construction site. The traffic environment analysis monitoring unit performs traffic environment analysis monitoring on the safety supervision area. The construction equipment analysis monitoring unit analyzes the real-time construction equipment in the safety supervision area, performs real-time safety monitoring on the safety supervision area through the analysis of real-time construction completion volume, monitors common features and makes targeted rectifications, and after the rectification is completed, the equipment operation safety risk unit performs operation safety risk analysis on the construction equipment in the safety supervision area. The invention avoids hidden dangers in the traffic locations around the construction area in the infrastructure construction site. Improve the safety of traffic in the safety supervision area, and avoid the abnormal traffic environment causing pedestrians or vehicles in the traffic area to be unable to effectively receive instructions, causing unnecessary safety accidents. The invention improves the safety of real-time completed buildings in the safety supervision area, minimizes the impact of building abnormalities, and ensures the safety performance of the safety supervision area. It ensures the equipment operation efficiency in the safety supervision area and avoids equipment operation abnormalities or equipment monitoring abnormalities, which will reduce the safety efficiency of the safety supervision area.

[0004] In view of the above scheme, it is found that: there is little analysis on the layout of emergency equipment at construction sites in the existing technology. The number of emergency equipment deployed to a certain extent reflects the demand for emergency equipment at the construction site, and the layout location of the emergency equipment is closely related to the convenience of use and construction for construction workers. At the same time, when analyzing the health status of construction workers, most of the health status thresholds of construction workers are compared. Due to the different number of emergency equipment in the area where the construction workers are located and the interference around the layout location, there is a certain impact on the health status threshold of construction workers. The existing technology ignores these aspects. On the one hand, it is difficult to ensure the rationality of the layout of emergency equipment at the construction site, and thus it is difficult to ensure the subsequent monitoring safety of the emergency equipment and the convenience of use for construction workers, reducing the value of the deployment of emergency equipment. On the other hand, when the emergency equipment is difficult to use in time, it is difficult to ensure the health of construction workers, resulting in casualties. Summary of the invention

[0015] 4. The present invention performs emergency equipment monitoring on the internal building area and the external building area in the equipment monitoring module, and generates an internal building sub-area risk set and an external building sub-area risk set taking into account the number of emergency equipment in the area where the construction personnel are located and the interference around the layout location.

[0016] 5. The present invention uses the health status index of each worker currently in construction and the adjusted health status threshold in the early warning processing terminal to judge the risk workers currently in construction, thereby overcoming the defect of neglecting this aspect in the prior art. When emergency equipment is difficult to use in time, the health of construction workers is protected and casualties are avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The simulated construction characteristic parameters of each internal building sub-area are imported into the safety level evaluation model, and the safety level of each internal building sub-area is obtained by output. The safety level of each external building sub-area is obtained by similar processing. The specific safety level evaluation model is: i =m,α i ∈α′ m , where ε i is the safety level of the i-th internal building sub-area, α i is the simulated construction characteristic parameter of the i-th internal building sub-area, α′ m is the simulated construction characteristic parameter interval corresponding to the mth security level stored in the web database, i is the number of each internal building sub-area, i=1,2,...,n, n is an arbitrary integer greater than 2, m is the number of each security level, m=1,2,...,l, l is an arbitrary integer greater than 2.

[0028] Based on the security level of each internal building sub-area, generate the internal building sub-area security level set A = {ε 1 ,ε 2 ,ε 3 ,,,ε n}, where ε 1 , ε 2 , ε 3 , ε n They are the safety levels of the first inner building sub-area, the second inner building sub-area, the third inner building sub-area and the nth inner building sub-area respectively.

[0029] Based on the safety level η of each external building sub-area p , p is the number of each external building sub-area, p = 1, 2, ..., q, q is any integer greater than 2, and generates a set of external building sub-area security levels B = {η 1 ,η 2 ,η 3 ,,,η q}, where η 1 , η 2 , η 3 , η q They are the safety levels of the first external building sub-area, the second external building sub-area, the third external building sub-area and the qth external building sub-area respectively.

[0030] In a specific embodiment of the present invention, the simulated construction characteristic parameters of each internal building sub-area are specifically analyzed in the following manner: based on the number of personnel in the simulated construction drill parameters of each internal building sub-area, combined with the spatial volume of each internal building sub-area, the personnel distribution density of each internal building sub-area is calculated.

[0031] It should be noted that the calculation obtains the population distribution density of each internal building sub-area, and the specific calculation formula is: divide the number of people in each internal building sub-area by the space volume to obtain the population distribution density of each internal building sub-area.

[0032] Based on the temperature fluctuation graph, humidity fluctuation graph, dust fluctuation graph, wind speed average Q in the simulated construction drill parameters of each internal building sub-area i , and the environmental safety characteristic values ​​of each internal building sub-area are obtained through numerical processing.

[0033] It should be noted that the environmental safety characteristic value of each internal building sub-area is specifically analyzed by: obtaining the temperature fluctuation value W based on the temperature fluctuation map, humidity fluctuation map and dust fluctuation map of each internal building sub-area i ″、Temperature mean W i , humidity fluctuation value S i ″、Humidity mean S i , dust content average F i , and calculated by the formula Calculate the environmental safety characteristic value of each internal building sub-area, where e is a natural constant, Where W i ′、S i ′、F i ′, Q i ′ respectively represent the suitable construction temperature, suitable construction humidity, suitable construction dust content, and suitable construction wind speed stored in the web database.

[0034] In a specific embodiment, the temperature fluctuation value is obtained based on the temperature fluctuation diagram of each internal building sub-area, and the specific method is: construct Y based on the temperature mean WI of each internal building sub-area i = WI, and obtain each wave point of the temperature fluctuation diagram of each internal building sub-area, and obtain the characteristic distance T between each wave point of the temperature fluctuation diagram of each internal building sub-area and the straight line ih , and then evaluate the temperature fluctuation value of each internal building sub-area h is the number of each wave point, h=1, 2, ..., g, and g is any integer greater than 2.

[0035] In another specific embodiment, the temperature fluctuation value obtained based on the temperature fluctuation diagram of each internal building sub-area can also be achieved in the following way: each wave point of the temperature fluctuation diagram of each internal building sub-area is obtained, and a straight line is formed by adjacent wave points, and the slope of the straight line of adjacent wave points is obtained to obtain each slope of the temperature fluctuation diagram of each internal building sub-area, and the slope fluctuation value of the temperature fluctuation diagram of each internal building sub-area is used as the temperature fluctuation value of each internal building sub-area.

[0036] The wave points mentioned above are specifically wave crest points or wave trough points.

[0037] Based on the height in the simulated construction drill parameters of each internal building sub-area, the risk factor corresponding to each internal building sub-area is obtained by multiplying it with the risk factor corresponding to the unit height stored in the web database.

[0038] The population distribution density, environmental safety characteristic values ​​and risk factors of each internal building sub-area are imported into the simulated construction characteristic parameter model, and the simulated construction characteristic parameters of each internal building sub-area are output.

[0039] Based on the simulated construction drill parameters of each external building sub-area, the simulated construction characteristic parameters of each external building sub-area are obtained through similar processing.

[0040] In a specific embodiment of the present invention, the simulation construction characteristic parameter model is specifically: Where M i , H i 、F i are the personnel distribution density, environmental safety characteristic value, and risk factor of the i-th internal building sub-area, respectively.

[0041] The present invention divides the infrastructure construction site into internal building areas and external building areas in the infrastructure area safety level division module, obtains simulated construction drill parameters of each internal building sub-area and simulated construction drill parameters of each external building sub-area, generates an internal building sub-area safety level set and an external building sub-area safety level set, and provides support for the subsequent deployment of emergency equipment in the internal building areas and the external building areas.

[0042] The equipment deployment assessment module is used to deploy emergency equipment in the internal building area and the external building area in sequence according to the internal building sub-area safety level set and the external building sub-area safety level set.

[0043] In a specific embodiment of the present invention, the emergency equipment deployment in the internal building area and the external building area is carried out, and the specific deployment process is: extracting the safety level of each internal building sub-area from the internal building sub-area safety level set, and obtaining the emergency equipment parameters corresponding to each safety level from the web database, and screening the appropriate emergency equipment parameters for each internal building sub-area.

[0044] It should be noted that the emergency equipment parameters include a required number of emergency equipment combinations, and the first aid equipment combination includes a first aid kit, a first aid bed, and first aid medicines.

[0045] Based on the appropriate emergency equipment layout parameters of each internal building sub-area, the unit layout volume of each internal building sub-area is constructed.

[0046] It should be noted that the volumes of the equipment in a group of emergency equipment combinations are integrated to obtain the unit layout volume of each internal building sub-area.

[0047] The bottom surface of each internal building sub-area is divided into regions according to the unit layout volume to obtain each sub-area of ​​each internal building sub-area, and each suitable layout sub-area of ​​each internal building sub-area is screened.

[0048] Through similar processing, suitable emergency equipment layout parameters for each external building sub-area and each suitable layout sub-area are obtained.

[0049] Emergency equipment is deployed in the internal building area according to the appropriate emergency equipment deployment parameters of each internal building sub-area and each suitable deployment sub-area, and emergency equipment is deployed in the external building area according to the appropriate emergency equipment deployment parameters of each external building sub-area and each suitable deployment sub-area.

[0050] In a specific embodiment of the present invention, the specific analysis method for screening the suitable layout sub-areas of each internal building sub-area is as follows: extracting the number of personnel and the number of equipment passing through from the simulated construction drill parameters of each internal building sub-area, and locating the number of personnel involved and the number of equipment passing through each sub-area corresponding to each internal building sub-area.

[0051] It should be noted that, based on the simulated construction drills conducted at the infrastructure construction site, the number of people involved and the number of equipment passing through each internal building sub-area corresponding to each sub-area were located.

[0052] Based on the installation points of the monitoring equipment reserved in each internal building sub-area, the monitoring volume of each sub-area of ​​each internal building sub-area is obtained.

[0053] Based on the number of people involved in each sub-area corresponding to each internal building sub-area R if , the number of equipment involved SL if and monitoring volume Vif , after numerical processing, the layout characteristic parameters of each sub-area of ​​each internal building sub-area are obtained.

[0054] It should be noted that the specific analysis method of the layout characteristic parameters of each sub-area of ​​each internal building sub-area is as follows: f is the number of each sub-area, f=1, 2, ..., t, and t is any integer greater than 2.

[0055] It should be noted that the mobility of personnel, the mobility of vehicles and the convenience of subsequent monitoring all affect the choice of the deployment area of ​​emergency equipment. If the mobility of personnel in a deployment area is higher, the mobility of vehicles is higher, and the convenience of monitoring is lower, it will affect the construction work of personnel, the passage of vehicles and normal monitoring, which is not conducive to subsequent construction and monitoring.

[0056] The sub-areas of each internal building sub-area are arranged in order from top to bottom according to the layout characteristic parameters, and the suitable layout sub-areas are selected based on the emergency equipment parameters of each internal building sub-area to obtain the suitable layout sub-areas of each internal building sub-area.

[0057] It should be noted that the specific method for selecting suitable sub-areas for layout based on the emergency equipment parameters of each internal building sub-area is as follows: based on the sub-areas of the sorted internal building sub-areas, in order from top to bottom, the sub-areas corresponding to the number of demand groups of each internal building sub-area are selected from the sorted sub-areas of the internal building sub-areas in turn, as the suitable sub-areas for layout of each internal building sub-area.

[0058] The present invention first evaluates the suitable emergency equipment parameters of each internal building sub-area in the equipment layout evaluation module, and then analyzes each suitable layout sub-area of ​​each internal building sub-area, which makes up for the deficiency of neglecting this aspect in the prior art, and ensures the rationality of the layout of emergency equipment at the construction site, thereby ensuring the subsequent monitoring safety of the emergency equipment and the convenience of use for construction personnel, and improving the value of the emergency equipment layout.

[0059] The equipment monitoring module is used to monitor the emergency equipment in the internal building area and the external building area, and generate an internal building sub-area risk set and an external building sub-area risk set.

[0060] In a specific embodiment of the present invention, the specific method for generating the internal building sub-area risk set and the external building sub-area risk set is: based on the video of emergency equipment monitoring of the internal building area and the external building area, the use frequency CI of the emergency equipment corresponding to each suitable sub-area of ​​each internal building sub-area is obtained. if , the volume of the obstacle areaVI if, after data processing, the constraint characteristic values ​​of each building sub-area corresponding to each suitable layout sub-area are obtained.

[0061] It should be noted that each building sub-area corresponds to a constraint characteristic value of each suitable layout sub-area, and the specific analysis method is as follows: Where CI′ is the estimated usage frequency of a group of emergency equipment combinations, VI i ' f The volume of each building sub-area corresponding to each suitable sub-area layout.

[0062] It is necessary to add that the frequency of use of emergency equipment in the deployment area and the volume of the obstacle area affect the adequacy, ease of use and ease of replenishment of emergency equipment in the deployment area. By using the constraint characteristic values ​​of each building sub-area corresponding to each suitable deployment sub-area, risky deployment sub-areas are screened, and important attention is paid to construction personnel in subsequent risky deployment sub-areas to prevent accidents and protect the health of construction personnel.

[0063] Through the risk judgment model, the risk layout sub-areas corresponding to each building sub-area are obtained, and the risk layout sub-areas are numbered as 1, 2, ..., j, ..., k, and then the internal building sub-area risk set C = {u1i, u2i, u3i,,,uki} is generated based on this, where u1 i 、u2 i 、u3 i ,uk i They are respectively represented as the first risk layout sub-area, the second risk layout sub-area, the third risk layout sub-area, and the kth risk layout sub-area corresponding to the i-th building sub-area.

[0064] It should be noted that the risk judgment model is specifically: Output the risk value θ of each building sub-area corresponding to each layout sub-area if , and record each layout sub-area with a risk value of 1 as each risk layout sub-area, and obtain each risk layout sub-area corresponding to each building sub-area, where σ′ is the preset constraint feature threshold.

[0065] After similar analysis and processing, a risk set of external building sub-areas is generated.

[0066] The present invention performs emergency equipment monitoring on internal building areas and external building areas in the equipment monitoring module, and generates an internal building sub-area risk set and an external building sub-area risk set, taking into account the number of emergency equipment in the area where construction workers are located and the interference around the layout location.

[0069] It should be noted that the risk affected areas of each current construction building sub-area of ​​the infrastructure construction site are specifically: the surrounding sub-areas of each risk layout sub-area of ​​each current construction building sub-area of ​​the infrastructure construction site, and they are summarized to obtain the risk affected areas of each current construction building sub-area of ​​the infrastructure construction site.

[0071] It should be noted that when carrying out infrastructure construction, construction workers usually wear technology bracelets, head-mounted helmets, safety vests or safety glasses to check their health status, so that timely warnings can be issued when the construction workers have physical abnormalities. The existing technology is relatively mature and will not be elaborated here.

[0072] It should also be noted that each construction worker with a health safety value of -1 is recorded as a risky construction worker, and the risky construction workers in each risk-affected area of ​​each current construction sub-area of ​​the infrastructure construction site are obtained.

[0073] In a specific embodiment of the present invention, the health status evaluation model is specifically:

[0074]

[0075] Where ξ ixb is the health safety value of the bth construction worker in the xth risk affected area of ​​the current i-th construction sub-area of ​​the infrastructure construction site, σix is the constraint characteristic value of the risk layout sub-area belonging to the x-th risk affected area of ​​the current ith construction sub-area of ​​the infrastructure construction site, K′ is the preset health status index threshold, and τ is the health status index reduction value corresponding to the preset unit constraint characteristic increase value.

[0076] The present invention judges the risky workers of the current construction according to the health status index of each worker currently under construction in combination with the adjusted health status threshold in the early warning processing terminal, thereby overcoming the defect of neglecting this aspect in the prior art. When emergency equipment is difficult to use in time, the health of the construction workers is protected and casualties are avoided.

[0077] The display terminal is used to display the internal building sub-area risk set and the external building sub-area risk set.

[0078] It should be noted that the present invention also includes a web database for storing simulated construction characteristic parameter intervals corresponding to each safety level, emergency equipment parameters and the volume of each equipment, suitable construction temperature, suitable construction humidity, suitable construction dust content, suitable construction wind speed, and risk factors corresponding to unit height.
