DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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. 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.

[0031] Combine the following Figures 1 to 6 The present invention describes a dust detection device based on a BIM smart construction site.

[0032] In one embodiment, a dust detection device based on a BIM smart construction site includes a sampling detection box 300, a limit frame 400, an air intake switch 500, a sampling detection component 600 and a BIM building information model; the sampling detection box 300 is installed on a fixed seat 100, and can be driven by the fixed seat 100 to lift and rotate; the limit frame 400 is rotatably sleeved on the sampling detection box 300, and the edge of the limit frame 400 is mutually engaged with the limit frame 200 provided on the fixed seat 100, and the limit frame 400 can move vertically along the limit frame 200; the air intake switch 500 is provided with a plurality of , and the air intake switch 500 is installed on the outside of the limit frame 400, which is used to control the air intake in the limit frame 400; the sampling detection component 600 is installed on the sampling detection box 300, which is used to evacuate the sampling detection box 300 so that the air intake switch 500 is opened under the action of negative pressure, and the external air can enter the sampling detection box 300 through the limit frame 400, and is also used to detect the air entering the sampling detection box 300; the BIM-based smart construction site system is communicated with the sampling detection component 600, and is used to process the detection results obtained by the sampling detection component 600 at each position.

[0033] Specifically, the sampling detection component 600 is communicatively connected with the smart construction site system, and the sampling state is selected according to the building position of the sampling detection component 600. For example, the fixing seat 100 is started to lift and lower the sampling detection box 300. When the sampling detection box 300 is lifted and lowered, it will also drive the limit frame 400 to lift and lower, and drive itself to rotate. When it is lifted and lowered to a certain height, according to the required state of sampling detection, the sampling detection component 600 at the corresponding position is controlled to evacuate the inside of the sampling detection box 300, so that the air intake switch 500 at the corresponding position on the limit frame 400 is opened. After the external air flows through the designated space in the sampling detection box 300, the sampling detection component 600 stops evacuating and detects the air inside the space, so as to obtain dust detection data. According to the dust detection data combined with the BIM model in the smart construction site system, the dust state of each area of ​​the building can be judged.

[0034] The above-mentioned dust detection device based on BIM smart construction site connects the sampling detection component 600 to the smart construction site system for communication, and selects the sampling state according to the building position of the sampling detection component 600. For example, the fixing seat 100 is started to lift the sampling detection box 300. When the sampling detection box 300 is lifted or lowered, it will also drive the limit frame 400 to lift or lower, and drive itself to rotate. When it is lifted or lowered to a certain height, according to the required state of sampling detection, the sampling detection component 600 at the corresponding position is controlled to exhaust the inside of the sampling detection box 300, so that the air intake switch 500 at the corresponding position on the limit frame 400 is opened. After the external air flows through the designated space in the sampling detection box 300, the sampling detection component 600 stops exhausting and detects the air inside the space, so as to obtain dust detection data. According to the dust detection data combined with the BIM model in the smart construction site system, the dust state of each area of ​​the building can be judged. The device can detect dust data in different locations and areas such as buildings as needed. The detection data is more accurate, which facilitates subsequent adjustments based on specific detection data.
