Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to an unmanned dynamic monitoring and control system for construction dust. Background Art

[0002] Construction sites, garbage recycling plants, and slag trucks will generate a lot of dust during operation, which will cause air pollution, increase the concentration of PM2.5 and PM10, and affect human respiratory health. Therefore, dust prevention measures need to be taken for places and equipment that are prone to dust generation.

[0003] Due to the characteristics of construction sites, construction sites are mostly divided into blocks. Existing dust removal systems generally include two methods: dust removal based on blocks or overall air quality. When a large amount of dust appears, it is often difficult to further control the dust end. For the overall construction site, dust control is often carried out by setting upper limit values ​​for multiple sensing points for spraying, which has poor controllability. Although there are solutions that simply combine the above two methods on the market, they are less targeted, resulting in poor correlation between the construction end and the overall situation. They can only be used as emergency remedies and lack controllability and immediacy.

[0005] The present invention aims to solve the problem in the prior art that due to the characteristics of the construction site, the construction site is mostly divided into blocks. The existing dust removal system generally includes two methods: dust terminal, that is, block-based dust removal or overall air quality. It is often difficult to further control the dust terminal when a large amount of dust occurs, and the dust control for the construction site as a whole is often carried out by setting upper limit values ​​according to multiple sensing points for spraying, and its controllability is poor; although there is a solution that simply combines the above two methods on the market, it is less targeted, resulting in poor correlation between the construction end and the whole, and can only be used as an emergency remedy, lacking controllability and immediacy.

[0010] The method for using the unmanned dynamic monitoring and control system for construction dust disclosed in the present invention comprises the following steps: S1. Importing a construction site map into the dust suppression control system, and setting positioning marks for the dust sensors of the ground dust sensor cluster and the working condition dust sensor cluster according to the actual location of the construction site; S2. Fitting the coordinate ground dust sensor cluster parameters in the construction road portion of the construction site map into a road dust state map based on the positioning coordinates, and fitting the dust parameters of the working condition dust sensor cluster in each construction block separated by the road in the construction site map into a construction block dust state map based on the positioning coordinates; S3, evenly arranging the mobile compensating dust suppression device on the construction road, starting the dust source auxiliary positioning mechanism to make it move toward the dust center according to the dust concentration collected at the current position; S4, compare the dust volume of the fitted boundary of each construction block with the dust volume of the adjacent road, and determine whether the difference is less than the block dust reduction failure threshold X, if yes, repeat step S4, otherwise proceed to step S5; S5. Arrange the fitted boundary dust amounts of each construction block that exceeds the block dust reduction failure threshold value X from large to small to generate a real-time dust failure sequence; S6, the dust suppression control system sends a real-time dust failure sequence to the mobile compensation dust suppression device at every dust suppression time interval T; S7, the mobile dust suppression compensation device receives the dust failure sequence and obtains the position signal of the ground dust sensor cluster; S8, extracting the corresponding construction blocks in the dust failure sequence according to the position signal of the ground dust sensor cluster to form a mobile dust reduction sequence; S9, the mobile compensation dust reduction device determines whether the maximum dust amount received by the current dust source auxiliary positioning mechanism is greater than the maximum dust amount at the first position in the mobile dust reduction sequence. If yes, the device continues to move toward the dust center, otherwise, it moves toward the road surrounding the construction area at the first position in the mobile dust reduction sequence.

[0011] The method for using the unmanned dynamic monitoring and control system for construction dust of the present invention is, as a preferred mode, the specific method of starting the auxiliary positioning mechanism of the dust source in step S3 to make it move toward the dust center according to the dust concentration collected at the current position is: The dust concentration sensor collects dust concentration in real time. The controller controls the vehicle to move forward while turning in the direction indicated by the sensor with the highest dust concentration. It also judges the distance between the vehicle and the position sensor of the road boundary position sensor cluster in real time. If it is less than the contact threshold, the vehicle will be rotated 90 degrees in the opposite direction of the position sensor.

[0012] The beneficial effects of the present invention are as follows: This system divides the dust area into two parts: the public connection area, i.e. the road, and the dust source, i.e. the block. The actual generation of dust is basically based on the block, and the construction activities are also based on the block. Therefore, in fact, the detection of whether the block is invalid or not and the dynamic supplementation of the invalid block are the fundamental ways to solve the dynamic dust.

[0013] In this method, a dynamic dust reduction crawler vehicle is used as a remedial solution for failed dust, and supplementary spraying is carried out between failed blocks or at dust sources that pre-generate a large amount of dust, so as to achieve the effect of limiting the failure degree of dust blocks, and keep the dust as close to the dust source as possible, so as to achieve a better overall dust control effect.
