Obviously, the embodiments described below 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 making creative work are within the scope of protection of the present invention.

[0031] The present invention provides an adaptive control method for construction dust treatment, which is used to solve the problems of poor effect and low efficiency of construction dust treatment methods in the prior art.

[0032] See also Figure 1 , Figure 1 This is a first flow chart of an adaptive control method for construction dust treatment provided by an embodiment of the present invention.

[0033] S100, obtaining historical construction records and dust concentration data, and constructing a relationship between the construction scale of each type of project and the concentration of each type of dust based on the construction time of each type of project and the change time of the dust concentration data in the construction records;

[0034] It should be noted that the construction time of each type of project will be recorded during the construction process, and the construction scale of different construction types will be recorded in the construction plan, such as the amount of excavation, vehicle transportation scale, material hoisting and transfer volume, blasting construction scale, etc. These construction scales directly affect the dust concentration generated; dust detection sensors will be installed at the construction site to detect the concentration data of dust of various particle sizes during the construction process, and obtain the dust concentration of various particle sizes at sensor monitoring points at different heights;

[0035] The construction records will contain the start and end times of various types of projects, and the dust concentration data will contain the relationship between dust concentration changes over time. Based on the corresponding time relationship, various types of projects can be associated with dust concentration changes, and based on the corresponding dust concentration changes under different project scales of the same type of project, the relationship between the construction scale of various types of projects and the concentration of various types of dust can be constructed. For example, operations such as earth excavation, vehicle rolling and transportation, and slag loading and unloading will produce dust mainly with larger particles of PM10, and the dust height is relatively low; while operations such as material lifting and transfer, high-altitude welding, and concrete spraying will produce PM2.5 fine particles of dust, which are more susceptible to airflow and wind force, suspended and diffused, and the dust height is about 10 meters; blasting and large machinery such as rotary drilling operations will also produce dust with smaller particles, and the dust height of these operations is relatively high, reaching more than 15 meters. In fact, all types of construction will produce dust of various particle sizes, but the concentration relationship of different particle sizes is different.

[0036] S200: Obtain the current construction plan and obtain dust forecast data based on the relationship between the construction scale of each type of project and the concentration of each type of dust generated; obtain meteorological forecast data, associate the meteorological forecast data with the dust forecast data based on the forecast time, and obtain the diffusion characteristics of each type of dust based on a preset dust diffusion model;

[0037] It should be noted that during the construction process, a construction plan will be planned in advance to ensure that the construction progress can meet the construction period. The daily construction content must be carried out according to the construction plan. Therefore, the construction plan of the current construction site can be obtained to obtain the current construction content to be carried out. The construction plan also includes the scale of construction. Therefore, based on the current construction plan and the relationship between the scale of construction of various types of projects and the concentration of various types of dust obtained in the above steps, it is possible to predict what concentration of dust will be generated by the construction to be carried out; meteorological forecast data can be obtained at the local meteorological station through the Internet to obtain the wind direction and wind speed changes during the future construction period, or wind sensors can be set up at the construction site to monitor wind direction and wind speed, and the monitoring data can be combined with the regional forecast data of the meteorological station to obtain wind speed and direction forecast data for the construction site. The obtained meteorological forecast data changes with time; and the dust forecast data also changes with time. Based on the time of meteorological forecast data and the time of dust prediction data, it can be obtained that each dust concentration will be affected by the wind speed and direction of meteorological changes at the corresponding time. Combined with the wind speed and direction, the diffusion of dust of different particle sizes with the wind can be predicted. For example, a dust diffusion model can be preset based on fluid mechanics to simulate the turbulent characteristics of the wind field in the construction area. After substituting the wind speed and direction in the weather data and the dust density of each particle size in the dust data into the model, the diffusion characteristics of dust of different particle sizes affected by wind speed and direction can be obtained; larger PM10 dust particles are easy to settle and diffuse slowly with the wind but are the most harmful, while smaller PM2.5 dust particles are easy to suspend and are more easily affected by rising air currents. In the dust diffusion model, the speed characteristics, concentration characteristics, height characteristics and direction characteristics of dust of different particle sizes when diffused with the wind can be obtained, which constitute the diffusion characteristics of various types of dust.

[0038] S300: Identify the first and second spraying devices according to the diffusion characteristics of various types of dust, and construct a spraying plan for the spraying devices; select the plan with the best dust suppression effect based on the spraying height and direction of the spraying devices of different spraying plans, and control the spraying devices.

[0039] It should be noted that, according to the diffusion direction in the dust diffusion characteristics, the spraying equipment around the construction area can be divided into the first spraying equipment through which the dust will directly pass, and the second spraying equipment through which the dust will not directly pass. The dust suppression angle that can be achieved by the first spraying equipment through which the dust directly passes is different from that of the second spraying equipment; then, a spraying scheme is constructed based on the dust suppression angle that can be achieved by the spraying equipment, and generally the spraying equipment is set up around the construction area. In the second spraying equipment through which the dust does not diffuse, part of the second spraying equipment can be closed according to the diffusion situation to reduce resource consumption and improve dust suppression efficiency, thereby obtaining multiple schemes. The spraying height and angle of the first and second spraying equipment are determined. Based on the spraying height and angle under the spraying scheme and the meteorological forecast data, the actual water curtain situation can be obtained. For example, under the weather data of a certain wind force and direction, the water curtain originally sprayed vertically at an angle of 90° by the first spraying equipment will be blown into a spraying water curtain at an angle of 100°, and the height of the water curtain will drop. The angle between the water curtain and the direction of dust diffusion will change, and the effect of intercepting the dust melt water will change. The spraying scheme with the best dust interception effect for different dust particle sizes is selected; different dust particle sizes can be preset to correspond to the best spraying angle, such as dust For large dust particles with low source concentration, 180° reverse spraying is the best, while for fine dust particles, 60-90° cross spraying is the best. When the wind speed is high and the diffusion speed of dust is also high, 120-150° tilted spraying can be used along the wind. Since there are multiple types of dust particles spreading from the first spraying device, it is necessary to set up a second spraying device to spray on the dust diffusion path of the first spraying device. The concentration of dust of different particle sizes is different. Based on the water curtain formed by each spraying scheme and the preset optimal spraying scheme for dust of each particle size, the water curtain height is proportional to the dust height. The system is used to judge the height ratio of dust that can be affected by the spray water curtain. When the height of the water curtain is greater than the dust height, the dust can be completely suppressed by the water curtain. The proportion of dust that can be suppressed and intercepted in the processed dust is judged according to the proportional relationship between the water curtain angle and the best dust suppression angle of the dust. The degree of dust suppression is calculated in combination with the concentration to obtain the dust suppression effect of each spraying scheme. In the spraying scheme selection, the scheme with the most suitable height of the spray water curtain can also be selected to increase the dust suppression efficiency and reduce water waste. The spraying scheme with the best dust suppression effect and efficiency is selected to control the first spraying equipment and the second spraying equipment.

[0040] In this embodiment, the relationship between construction scale and dust generation concentration is constructed by obtaining historical construction records and dust concentration data. In the current construction, the concentration of dust of various concentrations is predicted based on this relationship and the construction plan, and the diffusion of dust is obtained in combination with meteorological forecast data. The corresponding spraying scheme is adaptively constructed according to the diffusion situation, and the scheme with the best dust suppression effect on multi-particle size dust is selected to control the spraying dust suppression, thereby improving the treatment efficiency of construction dust, reducing resource waste, and improving the dust treatment effect.

[0041] The above is a detailed description of the first embodiment of an adaptive control method for construction dust treatment provided by the present application. The following is a detailed description of the second embodiment of an adaptive control method for construction dust treatment provided by the present application.

[0042] In this embodiment, an adaptive control method for construction dust treatment is further provided. In the aforementioned step S100, the relationship between the construction scale of each type of project and the concentration of each type of dust is specifically constructed as follows:

[0043] ;

[0044] in, is the concentration of dust of the nth type of particle size, is the dust emission coefficient of the mth type of project for the nth type of dust particle size, is the construction scale of the mth type of project, is the disturbed area of ​​the mth type of project, is the number of types of construction projects; different construction types mainly generate different dust particles. The dust coefficient of the mth type of project to the nth type of dust particle size can be constructed according to the proportional relationship between the dust generation concentrations of each particle size. The more dust of corresponding particle sizes generated by the construction, the larger the dust coefficient. The construction scale is also positively correlated with the dust concentration. Under the same construction scale, for example, if 100 cubic meters of earth needs to be excavated, the smaller the disturbance area, the smaller the space confined to the generated dust, and the corresponding dust concentration is greater. The dust concentrations of various particle sizes generated by various types of construction occurring in the same time period are accumulated to predict the dust forecast data under the construction plan.

[0045] Furthermore, obtaining the diffusion characteristics of various types of dust based on the preset dust diffusion model specifically includes: constructing a building model of the construction area and updating the building model of the construction area in real time according to the construction process; obtaining obstruction characteristics in the construction area based on meteorological forecast data and the building model of the construction area, and adjusting the preset dust diffusion model based on the obstruction characteristics to obtain the diffusion characteristics of various types of dust;

[0046] It should be noted that during the construction process, in order to monitor the construction status and obtain real-time construction site data, the building will set up a corresponding digital twin, which will be updated in real time with the construction progress. Therefore, the regional building model can directly call the real-time three-dimensional model of the digital twin, or a separate model can be built for the construction area. According to the meteorological forecast data, the wind direction can be obtained and the direction of dust diffusion can be determined. The situation in which the dust in the construction area will be blocked by the building model can be obtained in this direction; the preset dust diffusion model is based on fluid mechanics to simulate the turbulent characteristics of the wind field in the construction area. By updating the data of building obstructions in the wind field, the dust diffusion model is adjusted to make the diffusion characteristics of various types of dust more accurate.
