What is a "smart site"? What is it made of?

With the accelerated application of Internet, Internet of Things and digital technology, promoting the construction of "smart site" has become a breakthrough and focus to promote the transformation and upgrading of building methods, an important path to help the high-quality development of the construction industry, and an important means to realize the modernization of building safety production management system and capacity.

Based on BIM (Building Information Model) +AI (Artificial Intelligence) intelligent big data center and cloud platform, "Smart Site" integrates many management modules such as safety, quality, green construction and real-name labor registration system around the whole life cycle of construction projects, supports the information system of site management, interconnection and cooperation, intelligent decision-making and data sharing to assist supervision and management, comprehensively monitors the construction site, and forms an information, digital and visual system.

The application of information technology is like growing eyes, ears and noses on the construction site, seeing violations, hearing noises and smelling hidden dangers, and controlling the context of the construction site in real time and accurately. The application of the existing "smart site" in construction safety management includes:

? 1, personnel information security control, people are the core of security work and the most dynamic and flexible factor in on-site security management. It is of great significance for the safety management of the construction site to control the construction personnel efficiently and accurately in the "smart construction site".

A face recognition access control system is set up to register and manage the identity information and access of construction workers in smart sites in the real-name registration system, which can not only punch in the cards in real time, protect workers' rights and interests, but also regulate the access of workers and ensure the safety of construction workers. With the help of this system, personal identity information, skill level, salary account, etc. And establish a construction personnel information base to record workers' construction activities and attendance records conveniently and quickly.

2, mechanical equipment safety monitoring

There are hidden dangers of aerial work in tower crane, elevator and hanging basket, and the defects of protective devices or protective articles will lead to safety accidents. With the help of real-time monitoring system, the security risks of smart sites can be solved and facilities and equipment can be managed.

After the smart system is connected to the construction site, real-time monitoring equipment is installed in the operation floor, tower crane, construction elevator and other parts with potential safety hazards in the smart construction site, which can monitor the lifting weight, torque, amplitude, height, wind speed, collision avoidance and the load, number of people, upper and lower limits of the construction elevator in real time. All transmitted videos and collected data are displayed on the "smart site" cloud platform, and managers can also view them in real time through mobile terminals.

? 3, smart wear safety protection

Construction sites are mostly open-air, and construction workers are exposed to high temperature and cold working environment for a long time to carry out high-intensity work, especially aerial work, underground work or night work with poor light. A little relaxation may lead to a safety accident. Smart wearable devices such as smart helmets, smart bracelets and smart glasses can help construction workers to do safety protection.

For example, some face recognition terminals can detect whether workers' helmets and other equipment are wearing specifications, and even have the function of detecting the temperature and fatigue of construction workers, which provides a layer of security for the operation of heavy equipment such as tower cranes and dump trucks.

Although the development of the construction industry is relatively mature at present, compared with other industries, the construction industry is still a "high-risk" industry, and there are hidden dangers at any time and anywhere. Safe production is the untouchable bottom line of the construction industry. All smart construction sites should enhance the awareness of construction safety, standardize safety behaviors, promote safety culture, and always tighten the red line of safety production.

The construction and application of "smart site" can effectively prevent the occurrence of safety accidents caused by illegal operations, standardize construction management, reduce potential safety hazards, save manpower input, reduce operating costs, resolve risks in advance, and escort construction safety production.
