With the support of digital and intelligent technology, it pays attention to personnel behavior, safety, efficiency and health, and ensures the normal and orderly construction process.
10. The value of smart construction sites
1. Digitalization of the construction site
The construction process, safety management, personnel management, green construction and other key links of the construction site are collected in real time through intelligent hardware to realize the digitalization of construction site business.
2. Data networking
The construction of a smart construction site is a process of highly integrated data. Based on the collection of data from the front-end subsystems, the applications of each subsystem are integrated, and finally the integration is completed on the cloud platform and conveniently accessed through the Internet.
3. Intelligent management
The cloud platform and terminal integrate advanced computer intelligent judgment and analysis strategies, which effectively help managers focus on key issues, actively avoid risks, and optimize execution operations, thereby raising the management level to a new level of wisdom.
11. Labor real-name system management
In the past, the real-name system was difficult to operate, and there was a lack of certification of labor personnel. The project department had no way of understanding the background and work skills of the personnel present. The potential risks of employment were high and the cost of trial and error was high. The turnover of workers is large, and the management of traditional access cards is cumbersome and inefficient. Labor contracts, tertiary education, migrant workers’ insurance, and workers leaving the factory are often missing information, which is often a blank area of management, and there are no effective preventive measures.
Labor real-name system management has the following advantages: 1. Risk prevention: labor dispute risk, malicious salary demand risk, regional overage risk, wage payment supervision; 2. Promoting production: labor number monitoring, labor type matching, personnel flow monitoring, and personnel attendance; 3. Efficiency improvement: automatic generation of rosters, quick sign-in for training, quick counting of people, and quick submission of reports; 4. Cost control: monitoring of subcontracts, monitoring of contract performance and settlement, monitoring of labor costs, and monitoring of labor efficiency.
Labor real-name system management is the product of the combination of machine learning and multi-layer neural network. Using biometric identification technology, it has many advantages such as fast recognition speed, high accuracy, convenient information entry, strong cross-platform, simple hardware configuration requirements, and low cost. . Support ID, IC, RFID, ID card, fingerprint, face, iris, palm print multiple identity authentication methods, mobile phone mobile management, fast and convenient entry.
12. Tower Crane Monitoring and Management
With the extensive use of tower cranes in the construction industry this year, various tower crane operation safety accidents have occurred frequently due to violations of regulations and overruns of tower cranes and interference and collisions of tower crane groups, resulting in huge losses of life and property. The experience and lessons of safety accidents show that it is necessary to carry out timely and effective supervision on the use process and behavior of tower cranes in order to effectively control the risk factors and potential safety hazards in the operation of equipment, and to prevent and reduce the occurrence of safety production accidents of tower cranes.
Tower crane monitoring uses information sensing, microelectronics and instant communication technologies to monitor the main safety devices of tower cranes, including moment limiters, lifting weight limiters, amplitude limiters, slewing limiters and height limiters. Acquisition, recording, transmission and storage. When the tower crane is working, it needs to change the working conditions frequently according to the actual situation on the site for lifting operations, such as changing the lifting angle, the length of the boom, etc., and the maximum rated lifting capacity that can be lifted under different working conditions and the maximum working, The minimum variable amplitude is correspondingly different, so a set of devices is required to comprehensively monitor and judge the above parameters, make instructions on the working status of the crane, such as normal operation, full load, overload, variable amplitude exceeding the upper limit, and variable amplitude exceeding the lower limit, and correspondingly alarm, prompt, Control to ensure the normal operation of the tower crane.
Tower crane monitoring can automatically detect various signals of tower crane equipment and input them into the instrument for microcomputer processing, such as: weight signal, height signal, angle signal between the boom and the level, etc. The instrument can display various preset working condition parameters. Such as arm length, actual lifting capacity, working range, boom angle, wind speed, etc. The system can automatically continuously sample the performance parameters of the tower crane equipment and track them in real time. The microcomputer performs calculations, comparisons, and judgments, and sends out sound and light alarms at any time. Run in the safe direction, so as to realize automatic control.
Summary: "Smart construction site" uses the Internet of Things and cloud computing technology to combine construction site personnel, machinery, materials, methods, and environment organically, efficiently, and scientifically to realize the effective integration of engineering project business flow and various on-site monitoring source data flows. Combination and deep fit.
