[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. 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.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0026] The terms “first”, “second”, “third”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0027] It should be understood that the "system" used in the present invention is a method for distinguishing different components, elements, parts, portions or assemblies at different levels. However, if other words can achieve the same purpose, the words can be replaced by other expressions.

[0028] As shown in this specification and claims, unless the context clearly provides an example, the words "a", "an", "the", etc. do not refer to the singular, but also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0029] The flowcharts used in this specification are used to illustrate the operations performed by the system according to the embodiments of this specification. It is understood that the operations of each step are not necessarily performed precisely in order. On the contrary, the steps can be processed in reverse order or simultaneously. At the same time, other operations can also be added to these processes, or one or more operations can be removed from these processes.

[0030] The inventor of the present application has found that during the construction process, "dust / dust accidentally entering the eyes" is an important factor that increases the risk of objects / people falling. When dust / dust accidentally enters the eyes of construction workers, it is easy to cause construction workers to have a strong stress reaction and discomfort, which can easily cause the objects in the hands of construction workers to fall out of their hands, or touch other objects around them, thereby increasing the risk of objects falling or falling. In severe cases, it may also cause people to fall.

[0031] Although "dust / dust accidentally enters the eyes" is a common phenomenon in daily life, it can easily lead to serious consequences in engineering construction. In engineering construction, in addition to daily reasons that may cause "dust / dust accidentally enters the eyes", due to the particularity of the working environment, when it is windy or rainy, it will directly increase the probability of "dust / dust accidentally enters the eyes". Therefore, it is necessary to control the risk of "dust / dust accidentally enters the eyes" in windy and rainy conditions.

[0032] For details, please refer to Figure 1 This embodiment provides a construction safety management system, which includes: a data center 100 and a receiving end 200. The number of receiving ends 200 can be flexibly set according to actual needs, and this application does not make specific restrictions.

[0033] The receiving end 200 is connected to the data center 100 for communication, and the receiving end 200 is used by construction management personnel.

[0034] The data center 100 is used to execute security control processes, such as Figure 2 As shown in the figure, the security control process includes the following steps: S1. Construct a real-time 3D model of the construction object, which corresponds to the real-time construction progress of the construction object. The real-time 3D model matches the construction progress of the construction object, that is, the real-time 3D model is what the construction progress of the construction object is.

[0035] S2. Determine the dust collection surface of the construction object according to the real-time three-dimensional model, and the dust collection surface includes the outer surface of the construction object. The outer surface is the outer surface of the construction object in the current state. As the construction object is constructed, the degree of perfection of the construction object gradually increases, and its outer surface will also change as the construction progresses. For example, when the outer wall of the construction object has not yet been affixed with exterior wall bricks, its outer surface is the wall surface of the exterior wall. When the exterior wall is affixed with exterior wall bricks, its outer surface is the surface of the exterior wall bricks. For another example, a building needs to build 9 rooms arranged in a nine-square grid style on the same floor, but only the middle room has been built. At this time, the outer surface includes the outer wall surface of the middle room, and when the remaining 8 rooms are completed, the middle room is completely surrounded, and the outer surface no longer includes the outer wall surface of the middle room. And not limited to this.

[0036] S3. Obtain local meteorological data (including but not limited to: rainfall, wind force, wind direction, dust, etc.), and determine the dust collection amount of the dust collecting surface based on the meteorological data, the material of the dust collecting surface, and the exposure time of the dust collecting surface. This is because the amount of dust in the local air, the specific material of the dust collecting surface, and the time the dust collecting surface is exposed to the air will directly affect the amount and rate of dust adhesion on the dust collecting surface. Taking them into consideration comprehensively can more reasonably evaluate the dust adhesion of the dust collecting surface. It should be noted that when determining the amount of dust in the air based on meteorological data, the dust situation at the construction site can be further comprehensively considered to make a reasonable assessment of the amount of dust in the air around the construction object.

[0037] The exposure time is calculated from the time the corresponding dust collection surface is constructed most recently. This is because once an external surface is constructed, such as the exterior wall is tiled, the dust on the original exterior wall will be "eliminated". After the construction, a new external surface (the surface of the exterior wall tiles) will be formed, and the dust collection amount of this new external surface needs to be recalculated. The dust collection surface with a dust collection amount greater than or equal to the critical threshold is regarded as the influencing surface. The critical threshold can be flexibly set according to actual conditions and needs. The unit of measurement for dust collection amount can be thickness (for example: mm) or dust weight per unit area (mg / cm 2 ), but is not limited to this.

[0038] S4. Determine the wind force-direction data for the future period of time at the location of the construction object based on the meteorological data, and judge whether the dust on the dust collecting surface will be lifted up based on the wind force-direction data. When judging whether the dust on the dust collecting surface will be lifted up, only the wind force in the wind force-direction data can be used for judgment. As long as the wind force reaches the intensity that can lift the dust on the dust collecting surface, S5 is executed. Among them, the wind force-direction data refers to: the wind direction for the future period of time at the location of the construction object determined based on the meteorological data, and the corresponding wind force related data.

[0039] S5, if the judgment result of S4 is that it will be lifted up, the windward surface of the construction object (i.e., the surface that will be directly blown by the wind, the angle between the wind direction and the windward surface can be 90° or an acute angle less than 90°) is determined according to the wind force-wind direction data. If there is an influence surface in the windward surface, the airflow field around the construction object is determined according to the windward surface and the wind force-wind direction data, and the risk area is determined according to the airflow field. The risk area includes the influence surface in the windward surface and the downstream area of ​​the influence surface in the airflow field.

[0040] S6. Send the risk area and the corresponding time to the receiving end 200.

[0041] Through the above design, the risk of "dust / dust accidentally entering the eyes" of the construction object in the future can be evaluated according to meteorological data, and the risk areas where "dust / dust accidentally enters the eyes" may occur can be prompted to the construction management personnel, so that the construction management personnel can reasonably allocate construction work according to the actual situation of the project site, so as to facilitate the corresponding construction personnel to leave the corresponding risk area before the dust may occur, reducing the risk of "dust / dust accidentally entering the eyes" at the construction site, and further reducing the risk of objects / personnel falling.

[0042] In general, the engineering construction safety management system provided in this embodiment can further reduce the risk of objects / people falling due to external stimulation of construction workers, which has positive significance for improving the construction safety management system.

[0043] Furthermore, in S5, it also includes: determining dust intensity.

[0044] Dust intensity = a*D+b*Y+c*F. Among them, a is the first correction coefficient and a>0, D is the dust collection amount, b is the second correction coefficient and b>0, Y is the rainfall per unit time, c is the third correction coefficient and c>0, and F is the wind force.

[0045] When determining the risk area, the influence surface within the windward surface where the dust intensity is greater than or equal to the intensity threshold and the downstream area of ​​the influence surface in the airflow field are taken as the risk area.

[0046] It should be noted that the specific values ​​of a, b, c and the intensity threshold can be flexibly set according to actual needs, and this application does not impose any specific restrictions.

[0047] The greater the amount of dust collected, the greater the rainfall per unit time, and the stronger the wind force, the greater the intensity of dust stirred up in an instant (dust intensity) will be.

[0048] Through this design, the dust intensity can be evaluated and the risk areas corresponding to the dust intensity that may cause "dust / dust accidentally entering the eyes" can be prompted, thereby improving the accuracy of risk prompts and avoiding unnecessary prompt information.

[0049] Furthermore, the security control process also includes the following steps: S7. Determine the dust emission duration. Dust emission duration = (1 + d*De*Yf*F)*t. Wherein, d is the fourth correction coefficient, e is the fifth correction coefficient, f is the sixth correction coefficient and f>0. t is the reference duration.

[0050] S8. Send the dust emission duration to the receiving end 200.

[0051] It should be noted that the specific values ​​of d, e, f and t can be flexibly set according to actual needs, and this application does not impose any specific restrictions.

[0052] Among them, t can be used as the time that the dust raised stays suspended at the corresponding position under a certain dust collection amount (abbreviated as: standard dust amount) and a certain rainfall per unit time (abbreviated as: standard rainfall) in a windless state. At this time, when the actual dust collection amount is lower than the standard dust amount, d is a negative number; when the actual dust collection amount is equal to the standard dust amount, d is 0; when the actual dust collection amount is higher than the standard dust amount, d is a positive number; when the actual rainfall per unit time is lower than the standard rainfall, e is a negative number; when the actual rainfall per unit time is equal to the standard rainfall, e is 0; when the actual rainfall per unit time is higher than the standard rainfall, e is a positive number.

[0053] Through the above design, the duration of dust can be reasonably evaluated, which makes it easier for management personnel to plan the evacuation time for construction workers, thereby minimizing the impact on normal construction in terms of time.

[0054] Furthermore, the dust collection surface also includes the inner surface of the construction object, and the conditions that the inner surface needs to meet include: (1) the inner space has at least two channels connected to the outside of the construction object; (2) the channels are distributed on different sides of the inner space.

[0055] For inner surfaces that meet the above conditions, the above method can also be used to conduct risk assessment, so that the dust situation in the passages of the corresponding internal spaces can be more reasonably assessed.

[0056] The engineering construction safety management system provided by the embodiment of the present invention can effectively evaluate the dust conditions near the outer surface of the construction object and in the passages connecting certain internal spaces with the outside, helping to reduce the probability of "dust / dust accidentally entering the eyes" of construction workers.

[0057] In summary, the engineering construction safety management system provided by the embodiment of the present invention can further reduce the risk of objects / personnel falling due to external stimulation of construction workers, which has positive significance for improving the construction safety management system.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
