Meanwhile, the video monitoring module monitors the display pictures of each test point in real time through the cameras installed on each test point and the displays connected with the cameras, extracts the display pictures appearing in the time periods corresponding to the test points where the reporting information is received by the reporting module and stores the extracted display pictures in the display pictures to be processed, and is convenient for tracing and recording the working conditions of the test points which send the credible reporting information in time after artificial determination. The reported information in this embodiment not only includes the reported information of the illegal operation transmitted by the tower crane collision avoidance control unit, but also includes the abnormal information transmitted by each unit of other modules.
Meanwhile, the environment monitoring module monitors PM2.5, PM10, noise, environment temperature, wind speed and other environment factors in real time through environment sensors arranged at various positions, when PM2.5 is found to exceed a preset value, various spraying devices arranged in a construction site are started to work through a spraying control unit in the on-site production management module, dust emission is reduced through sprayed liquid, and the spraying devices are stopped to work until PM2.5 is detected to be smaller than the preset value. Therefore, the construction environment can be effectively ensured to be always in a proper environment, and energy can be saved as much as possible.
PM2.5 is fine particles, also called fine particles and fine particles, and refers to particles with the aerodynamic equivalent diameter of less than or equal to 2.5 microns in ambient air. It can suspend for a long timeIn air, the higher the content concentration in air, the more serious the air pollution. Although PM2.5 is only a component of earth's atmospheric composition in small amounts, it has a significant effect on air quality and visibility, among other things. Compared with the thicker atmospheric particulate matters, the PM2.5 has small particle size, large area, strong activity, easy attachment of toxic and harmful substances (such as heavy metals, microorganisms and the like), long retention time in the atmosphere and long conveying distance, thereby having larger influence on human health and atmospheric environmental quality. The PM2.5 preset value in the embodiment adopts the daily average value of 75 mu g/m in the air quality standard3On the basis of the construction method, the method is obtained by combining the particularity of the geographical environment of the construction site. The PM2.5 preset value of the implementation is 69-75 mu g/m3. Except triggering the start spray set through reaching the default, environmental monitoring module still monitors prestoring historical data in the appointed fine particles of while section, appointed fine particles for the great fine particles of job site place region environmental impact, for example in Kunming, pollen can monitor as appointed fine particles as the fine particles of conventional PM2.5 monitoring like this, avoids its influence to staff's production. More importantly, except for real-time monitoring, the environment monitoring module predicts all fine particulate matters and specified fine particulate matters in PM2.5 as well as monitoring and predicting the wind speed by the tower crane anti-collision control unit, and if the prediction result is that the PM2.5 can rise to a preset value in a certain time period, the spraying device is started in advance for spraying and dedusting half an hour to 40 minutes in advance.
Meanwhile, the environment monitoring module monitors the environmental factors such as PM10, noise, environmental temperature and the like in real time through various existing environment sensors, when the actual measurement parameters of various environmental factors exceed preset values, the environment monitoring module forms corresponding description information as report information and sends the report information to the reporting module, and the reporting module reminds that the corresponding environmental factors are in abnormal conditions through a display device, a display, a portable terminal of constructors and a network platform of a field production management module which are connected with the reporting module.
Meanwhile, the access control unit compares the personnel information according to a preset access control passing mode by identifying various access control authorization levels, opens access control release if the comparison is successful, forms report information and sends the report information to the report module if the comparison is failed, and simultaneously displays the picture information through a network platform of the field production management module. Can effectively avoid irrelevant personnel to enter into the job site.
In addition, when underground construction operation is performed, the underground control unit monitors the underground construction operation environment in real time by controlling the monitoring equipment connected thereto.
In this embodiment, a construction management system is constructed on the basis of the existing BIM model, and intelligent management is performed on a construction site. The method solves the problem that the existing construction site management can not fully utilize the existing system to carry out intelligent management, and can fully combine the site environment of the construction site by utilizing the existing system to carry out intelligent management.
Example two
In this embodiment, a monitoring position adjustment table is preset in the underground control unit. When the construction site is loose in soil and needs to be tamped and backfilled, the underground control unit dynamically moves the monitoring position of the monitoring equipment according to the backfilling progress through the monitoring equipment connected with the underground control unit, can transmit the underground construction condition to the on-site production management module through the underground control unit in real time, and displays the underground construction condition through the network platform. In the embodiment, in order to better control the accurate movement of the monitoring equipment installed underground, the track which can be wound is timely arranged along the tunneling direction in the process of tunneling along with underground excavation, scales are arranged on the track, and the bottom end of the monitoring equipment is connected with a rail car which can travel on the track. The monitoring position of the monitoring device is moved by controlling the movement of the rail car on the track. When soil is backfilled, the rail car drives the rail to wind in the process of moving outwards, so that the rail car also drives the wound rail to wind and complete the winding after the excavation pit is completely backfilled. This embodiment not only can be accurate the control position of adjusting supervisory equipment, can also retrieve track and railcar automatically.
EXAMPLE III
In this embodiment, a mode of identifying a worker who is present in a construction site for seven days or less by an IC Card (Integrated Circuit Card, also referred to as a smart Card) is used as an access control passing mode. Workers who appear on a construction site for more than seven days are used as an access control passing mode through an NFC (Near Field Communication) identification mode. And for workers with less than or equal to seven days but inconvenient operation, an NFC identification mode is adopted as an access control passing mode. For the access control of a particularly important position, a face recognition mode is adopted as an access control passing mode. The biggest difference from the prior art is that the face recognition mode in the embodiment needs to assist in height detection, namely, a height calculation rule is preset on the face recognition device, other components do not need to be additionally added, and only two or more pictures of the whole body image of a worker need to be taken when the worker approaches the face recognition device, and the height of the recognized person can be calculated while face recognition calculation is carried out according to the distance between the worker and the face recognition lens. Therefore, the accuracy of face recognition can be properly reduced, and the operator can also finish comparison operation through face recognition and height recognition when the operator is a local face polluted by dust. Therefore, the system is more suitable for being used in a construction site, can reduce the setting cost by reducing the face recognition precision, and can achieve the purpose of authorized management of entrance guard.
In this embodiment, start to take a candid photograph whole body image to the staff when the staff is 5 meters away from face recognition device, take a candid photograph many whole body images in succession with speed one per second, when the staff walks to face recognition device's distance within a meter and carry out face recognition. Because the positions where the workers stand during the face recognition process are arranged in advance, the distances between the workers are determined, and the distances between the workers from far to near to the face recognition device are also determined in advance. Therefore, when the worker performs face recognition, the distance between the positions of the worker when two adjacent whole-body images are shot can be recognized through three selected whole-body images, the body length of the worker in the corresponding whole-body image can be recognized through the existing image recognition technology, and the actual height of the worker can be calculated through a triangular side length calculation formula. Because such calculated amount is very little, can carry out height discernment in face identification, compare this staff's face information and height information with preset personnel's information, can pass through verification on the contrast, open entrance guard. Just because of the assistance of height detection, the scanning point of the face recognition at the stage can be reduced to sixty percent to seventy-five percent of the original scanning point, the precision requirement on the face recognition device is slightly reduced, and the input cost is greatly reduced.
Example four

When the temperature is abnormal, the air conditioner is started to reduce or increase the temperature. When the noise exceeds the standard, the noise reduction cloth is opened to carry out noise reduction treatment on the space where the operator is located. When the humidity is too high or too low, the dehumidifier or the humidifier is started to work respectively. Therefore, the construction site can meet the construction requirements and can meet the comfort level of the human body as much as possible. Can effectively reduce the possibility of occupational diseases. More importantly, in this embodiment, dehumidifier and humidifier all set up on the amortization encloses cloth, simple to operate, and do not occupy additional space, the emergency equipment of being convenient for place and install, be convenient for in time launch emergency equipment.
