Description

Technical Field

[0001] The present invention belongs to the technical field of municipal engineering construction safety management, and specifically relates to a municipal engineering construction safety intelligent management system and method. Background Art

[0002] In the field of municipal engineering construction, safety management has always been a crucial link. With the acceleration of urbanization, the number of municipal projects continues to increase, and the scale and complexity of construction are also increasing, which puts higher requirements on construction safety management. At present, there are some relatively complete safety management systems on the market. These systems mainly rely on manual supervision, equipment supervision, and multi-party collaborative supervision to ensure the safety of municipal engineering construction.

[0003] However, with the development of cities and the continuous improvement of infrastructure, municipal facilities such as roads, green belts, and pipelines often need to be expanded, renovated, or repaired. In this process, due to the small amount of work, most of the current construction does not have perfect safety supervision and relies entirely on the construction team's own management capabilities. Moreover, the construction area is usually located in the main roads of the city or busy traffic areas, with dense traffic and pedestrian flow and complex traffic conditions, which aggravates the construction risks. In particular, many of the above-mentioned projects are contracted by small contractors without sound management measures. In this case, if there is a lack of a complete safety management system, it will be difficult to ensure the safety and stability of the construction process if it relies solely on construction supervisors for management.

[0004] Based on this, in order to solve the above problems, the present invention provides a municipal engineering construction safety intelligent management system and method. Summary of the invention

[0059] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0060] Figure 1 This is a principle block diagram of the present invention. DETAILED DESCRIPTION

[0061] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. 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.

[0062] like Figure 1 As shown, a municipal engineering construction safety intelligent management system includes a platform end and a user end;

[0063] The platform end includes a construction analysis module;

[0064] The construction analysis module is used to analyze the construction information uploaded by the user. The platform presets a municipal information map, obtains the user's construction information, and marks the construction supervision area in the municipal information map according to the construction information. The construction supervision area is the area where the municipal construction needs to be supervised for safety, and is generally composed of the construction area and its possible transition area;

[0065] Conduct safety management analysis on construction information to obtain a safety management plan; generate a three-dimensional data model based on the safety management plan and construction supervision area, mark it as a safety deployment model, and mark the purpose, function, effect and other equipment introduction data of each safety device in the safety deployment model; send the safety deployment model and safety management plan to the user end.

[0070] In one embodiment, the method for screening various solutions is to screen based on existing technologies, such as feeding back various solutions to users, and allowing users to select corresponding solutions as target solutions.

[0071] In one embodiment, the method for screening various solutions includes:

It can be set according to the corresponding safety protection effect, accident incidence rate after application, etc. For example, define the value range of the effectiveness value as [60, 100], that is, the lowest standard effectiveness value that can be used as a solution is 60, which is the maximum allowable hazard occurrence probability. If no corresponding safety hazard has occurred after application, the effectiveness value is 100, and other values are reduced accordingly according to the hazard occurrence probability to obtain each effectiveness value; for example, the highest allowable hazard probability incidence rate is marked as A, and then 0 - A corresponds to 100 - 60, such as 0.5A corresponds to 80, and then calculate the effectiveness values of each hazard incidence rate according to the hazard incidence rate.

[0075] Mark the obtained effectiveness value as XGi, where i represents the corresponding safety hazard, i = 1, 2,..., n, and n is a positive integer;

[0076] According to the formula Calculate the method values of each solution;

[0077] In the formula: PA is the method value; b1 and b2 are both proportionality coefficients, and the value range is 0 < b1 ≤ 1, 0 < b2 ≤ 1; CB is the safety cost; βi is the weight coefficient of the corresponding safety hazard, which is set according to the loss proportion of all safety hazards occurring.

[0083] The security equipment models and background models are combined according to the target installation combination method to obtain a security deployment model.

[0084] In one embodiment, the impact change value corresponding to each potential installation combination method adjusted from the target safe combination method is determined according to the screening process of the installation combination method, that is, each impact value is determined and calculated according to the screening process of the installation combination method.

[0088] The safety deployment module is used to set various safety devices, which refer to various safety devices used in the safety management solution, such as cameras, fences, warning signs, etc.; the safety deployment model and safety management solution sent by the receiving platform are adjusted by the user according to the needs, such as replacing different types of safety equipment, adjusting the position of each safety equipment, etc.; the safety deployment model adjusted by the user is marked as a deployment transition model;

[0089] The platform loads and sets the adjustment assessment model at the user end. The adjustment assessment model is used to analyze the layout transition model and determine whether the layout transition model meets the safety requirements of the safety management plan. That is, adjustment operations such as replacement and movement of safety equipment can be performed, but it cannot cause it to fail to meet the corresponding construction safety requirements. The layout transition model is analyzed by the adjustment assessment model to obtain the corresponding adjustment assessment results;

[0090] When the adjustment assessment result is qualified, the deployment transition model is marked as a deployment application model;

[0091] When the adjustment evaluation result is that the adjustment is unqualified, the user is prompted to readjust or return to the original state until the deployment application model is obtained.

[0092] Arrange various safety devices according to the deployment application model.

[0093] In one embodiment, the adjustment evaluation model is established based on the existing technology, as long as the corresponding analysis and judgment can be achieved.

[0096] It means that the layout transition model is checked based on the safety requirements to determine whether it meets the safety requirements. The judgment is made based on the existing verification judgment method and is expressed by the above expression, which does not reflect the corresponding judgment process.

[0097] By adjusting the evaluation model for analysis, the corresponding adjusted evaluation value is obtained;

[0098] When the adjusted assessment value is 1, the assessment adjustment is qualified;

[0103] Where: PBt is the cumulative evaluation value; [t1, t2] are the two time endpoints of the evaluation period, which is set according to user needs, such as one day, three days, one week, one month, etc.; t2 is the current time;

[0104] When the cumulative assessment value is greater than the threshold X1, it indicates that the accumulated risk hazards during the assessment period exceed the user requirements; the assessed safety awareness does not meet the standards; and it is integrated into the safety awareness assessment result.

[0105] Integrate the conditional safety analysis results, operation safety analysis results, comprehensive assessment curves and safety awareness assessment results into safety supervision data, and display the safety supervision data to users.
