All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 shows a schematic structural diagram of a construction environment monitoring and management system according to an embodiment of the present invention, where the construction environment monitoring and management system includes an air monitoring device, a spraying device, a camera device, and a control center;
the air monitoring equipment, the spraying device and the camera shooting equipment are electrically connected with the control center, and a plurality of spraying devices are arranged around the construction site. The guard bands such as baffle or guardrail can be set up around the building site generally, evenly install a plurality of sprinkler on the guard band, sprinkler sprays water smoke around to, forms the dust adsorption scope, and the dust adsorption scope that two adjacent sprinkler formed exists the cross region, will form the absorption barrier that links up between a plurality of sprinkler like this, avoids letting the dust dissipation in the building site to the resident living area around the building site.
The air monitoring equipment is used for uploading the monitored air quality data to the control center; the camera equipment is used for uploading the video data collected by monitoring to the control center. The air monitoring equipment can only carry out closely monitoring, only can be monitored when the dust escapes to the vicinity of the air monitoring equipment, and the camera equipment can monitor the environment at a distance, can analyze through the image shot, can monitor whether dust exists in the air, and especially obvious dust air mass is yellow or gray, can monitor through the video.
The control center is used for comprehensively analyzing and processing the air quality data and the video data, and sending a starting instruction to the spraying device when the dust content in the air exceeds the standard through analysis and judgment.
The spraying device is used for receiving the starting instruction and carrying out adsorption treatment on dust in the air so that the dust content in the air is smaller than a preset threshold value.
The air monitoring device and the image pickup device may be provided in plurality along the periphery inside the site, for example, the air monitoring device 1 (1 st air monitoring device), the air monitoring device 2 (2 nd air monitoring device),. The air monitoring device n (n-th air monitoring device) in fig. 1; image pickup apparatus 1 (1 st image pickup apparatus), image pickup apparatus 2 (2 nd image pickup apparatus), image pickup apparatus n (n-th image pickup apparatus); the air monitoring equipment is larger than the camera equipment in distance from the protective zone and is closer to the inside of the construction site, so that the air monitoring equipment can monitor dust in advance, and the spraying device is opened in advance to form an adsorption barrier.
In the embodiment, the air environment in the construction site is monitored through the air monitoring equipment and the camera equipment, so that not only can the air quality in the near site be accurately monitored, but also the air environment in the remote site can be roughly monitored, the monitoring force on the construction environment is enhanced, then the control center comprehensively analyzes the air quality data and the video data, and controls the spraying device to form an adsorption barrier in advance, so that dust in the air is adsorbed, the dust dissipation to a residential living area is reduced, the treatment intensity is improved, and the air pollution is reduced.
In one embodiment of the present invention, the control center is configured to perform comprehensive analysis processing on the air quality data and the video data, and issue a start command to the spraying device when the analysis determines that the dust content in the air exceeds the standard, where the method includes:
intercepting a picture in the video data, and analyzing the definition of a reference object in the picture and whether dust air clusters appear in the picture;
judging whether the definition is smaller than a preset definition;

judging whether the air quality data is larger than a preset threshold value or not;
and when the air quality data is larger than a preset threshold value, the control center issues a second starting instruction to the spraying device so as to control the water pump in the spraying device to start.
And when the air quality data fall back to be smaller than the preset threshold value, sending a second stop instruction to the water pump. When the air quality data monitored by the air monitoring equipment is smaller than a preset threshold value, the air in the construction site is temporarily clean, the air can be not treated, and the water pump is turned off at the moment, so that the spraying device is thoroughly stopped.
In this embodiment, air monitoring equipment sets up in the construction site apart from the guard band certain distance, and when air pollution is not obvious but air pollution degree exceeds standard again, can be through the accurate content of dust in the monitoring of air monitoring equipment, strengthen the monitoring dynamics to the environment. Because the dust density in the air is not very big at this moment, diffusion rate is slower, so can not need not open sprinkler too much time in advance, avoid spraying useless water, cause the wasting of resources.
It should be noted that, the image capturing device and the air monitoring device may be set to a plurality of spraying devices for controlling the positions of different areas, because the image capturing device observes the remote air quality condition, when the dust air mass appears, the image capturing device in a plurality of directions may all shoot, at this time, the control center analyzes the video data and controls the spraying devices in a plurality of directions to start working, but in practice, the dust air mass may not escape in all directions, only escapes in one or a plurality of directions, so a countdown function is added in the control center, the control center issues a start command to the spraying device corresponding to the direction in which the image capturing device for monitoring the dust air mass is located, and when the spraying device is controlled to work, the countdown function is automatically started, the working time of the spraying device is started to be countdown, at this time, the spraying device is in a short-time working state; during the countdown period, the control center analyzes the air quality data uploaded by the air monitoring equipment in the direction of the started spraying device, and when the control center analyzes that the air quality data in a certain direction exceeds the standard before the countdown period is finished, the control center continuously maintains the spraying device in the certain direction to work, and the spraying device is in a normal working state; however, before the countdown is finished, if the air quality data in a certain direction is analyzed by the control center and is not out of standard, the control center issues a pause instruction to the spraying device in the direction, and the spraying device in the direction is controlled to stop working.
