Based on the Internet of Things and mobile Internet technology, the smart construction site app uses various sensors and terminal equipment to provide environmental monitoring, real-name labor management, material management, inspection records, and equipment management for construction site managers through real-time data interaction with cloud servers. and a series of high-quality and efficient industry solutions.
1. Application value of smart construction sites
The smart construction site has built a universal management platform for intelligent data sensors based on the Internet of Things. Utilize computers, artificial intelligence, and wireless communications to provide all-weather on-site monitoring, construction inspection, quality management, and services to improve on-site management capabilities such as digital management, safety, green, and construction, marking the entry of on-site management into the information age.
First, macroscopic analysis of the application value of smart sites from the perspective of industrial construction
Support industrial digital upgrade
The construction industry-related projects are numerous and widely distributed, making centralized supervision difficult. This is an important problem in the field of engineering technology.
The promotion of intelligent on-site applications will enable the visualization of construction elements such as humans, machines, materials, methods, and environments, which will be of greater help in completing the digital upgrade of the engineering technology industry.
Increase industry profit margins
Smart construction site application projects can be carried out in previous generations of Pearl institutions, using information technology to strictly transition and follow construction. Therefore, secondary handling and materials are reduced, waste is eliminated, and all costs and expenditures are well-founded, reasonable and reliable.
Improve labor utilization
As age increases, the production of each worker gradually decreases. Not only will there be on-site applications, but in order to improve the work efficiency of workers to a certain extent, they can also replace part of the workers' work. For example, use software to replace commuting, conduct signature approval online, and use manual monitoring to replace AI hazard identification, etc., to fully release the labor force and increase the per capita output rate.
Strengthen industry supervision capabilities
The three-stage cooperation of "construction authorities, enterprises, and projects" includes the establishment of a "smart construction site" information management platform. Through data cooperation in all aspects, the content and data related to on-site safety and quality supervision are presented through an intelligent integrated platform to achieve digitization. Supervision and management. Comprehensive use of big data analysis to achieve intelligent monitoring of regional projects and effectively prevent risks. Strengthen prior surveillance to reduce accidents.
Improve the quality of the construction environment
The person in charge of intelligent engineering said that the Internet of Things and cloud computing technology use real-time and remote automatic monitoring of particulate matter concentration, noise decibels and civilized construction conditions at construction sites to reduce environmental pollution throughout the city and improve citizens' healthy living index.

3. Introduction to smart construction site system functions
【Project Personnel Management】
1. Project management: project name, name of construction unit, project address, total cost, total area, construction permit, start date, planned completion date, project status, etc.
2. Personnel information management: Supports the collection of ID cards and face information; maintains basic information, certificate information, contract information, training information and other data.
3. Attendance management: Supports multiple check-in methods such as safety helmets and mobile phones, records entry and exit times, and counts working hours; partition management, attendance records, and salary payment.
4. Access control management: Establish labels for special personnel and management personnel to facilitate personnel inquiry and unified management.
5. Safety education: Wireless WIFI is provided at the construction site. Workers need to be certified and answer built-in questions before accessing the Internet. After passing the certification, they can access the Internet. The system pushes different types of questions or video content according to the type of logged-in personnel. Questions or videos are set differently according to their importance. The weight is pushed randomly.
【Video Surveillance Management】
Video surveillance viewing, video surveillance playback, AI hazard source identification, and AI application overview.
Through video surveillance + intelligent analysis, it can be determined whether safety helmets are worn at main entrances and exits or in specific places. When it is detected that a safety helmet is not worn, the alarm will be reported immediately to reduce safety accidents. The loitering monitoring function can be deployed in key areas to proactively trigger an alarm when abnormal loitering people are found.
[Crisis and major project management]
1. Machinery, equipment and driver identification:
All tower cranes and lifts are equipped with biometric authentication functions such as face or fingerprint to ensure that personnel are certified to work; driver information is uploaded to the smart construction site platform in real time.
2. Tower crane monitoring:
It can monitor important operating parameters in real time, including weight, torque, height, amplitude, rotation angle, operating speed, and wind speed; when the tower crane operates dangerously, real-time alarm data will be pushed to the smart construction site platform.
3. Hook visualization:
The visual video screen supports real-time viewing and remote browsing in the cab, computer, and mobile phone;
4. Lift operation monitoring:
Real-time monitoring of load, car inclination, lifting height, running speed and other parameters; when an abnormality occurs, an audible and visual alarm will be issued immediately in the car, and the alarm data will be pushed to the smart construction site platform.
5. High support mold monitoring system:
Real-time monitoring of high-support formwork poles, tilt angles and loads, as well as horizontal displacement of the frame and settlement of the formwork; when the detection data exceeds the warning value, a real-time alarm is sent to the cloud platform.
6. Deep foundation pit monitoring system:
Real-time monitoring of the horizontal displacement of the top of the supporting structure, horizontal displacement of the deep layer, horizontal displacement of the column top, settlement, internal force of the support structure and anchor cable stress of the deep foundation pit, and alarming for excessive warning data.
【Green Construction Management】
Real-time environmental monitoring, historical environmental monitoring data, spray task management, automatic spray painting records, intelligent analysis of muck trucks, and vehicle entry and exit records
1. Environmental monitoring:
Real-time display of PM2.5, PM10, temperature, humidity, wind speed, wind direction, and noise data; the smart construction site platform can set alarm values and early warning values, and can push early warning information in time when an alarm occurs.
2. Dust monitoring:
The smart construction site platform can set early warning values for particulate matter indicators. When it detects that the concentration of particulate matter exceeds the standard, the system automatically starts the spray equipment to achieve autonomous dust reduction; the mobile APP has a remote control function.
3. Vehicle washing AI recognition:
By installing a muck truck vehicle flushing identification device at the entrance and exit of the construction site, it can automatically identify whether the muck trucks have been fully flushed in accordance with regulations before going out on the road, and alarm the muck trucks that are detoured, not flushed, or insufficiently flushed. Report information and video evidence.
4. Water and electricity monitoring:
A new water and electricity metering model based on Internet of Things technology that automatically remotely reads water and electricity meter data, sets thresholds, and automatically determines abnormal conditions.
