Internet plus Internet plus has been a hot trend with the development of Internet technology, communication technology, sensor technology and Internet of things. In this upsurge, what smart building, intelligent engineering, intelligent construction site and so on emerge as the times require.

From the perspective of smart engineering (construction site), smart construction site refers to the accurate design and construction simulation (BIM Technology, etc.) of engineering projects through three-dimensional design platform by using information means, establishing an information ecosystem of construction projects with interconnection, collaboration, intelligent production and scientific management around construction process management, and collecting this data with the Internet of things in the virtual reality environment (sensors, instruments, etc.) to carry out data mining and analysis of the project information, provide process trend prediction and expert plan, and realize visual and intelligent management of project construction, so as to improve the informatization level of project management, so as to gradually realize green construction and ecological construction.

Smart construction site embeds more high-tech technologies such as artificial intelligence, sensing technology and virtual reality into various objects such as buildings, machinery, personnel wearing facilities and site entrances and exits, which are generally interconnected to form a "Internet of things", and then integrated with the "Internet" to realize the integration of project management stakeholders and project construction site. The core of the smart project site is to improve the way of interaction between various stakeholder organizations and post personnel in a "smarter" method, so as to improve the clarity, efficiency, flexibility and response speed of the interaction.

From a technical point of view, from modules to system platforms, their establishment is mainly divided into:

1. Data acquisition: it is mainly the source of real-time data from various sensors, data interface retrieval, manual upload and input, etc

2. Communication layer: at present, data transmission is divided into wired transmission and wireless transmission. Wired transmission is only in the form of bus, video fiber, etc. wireless transmission includes GPRS, 3G, 4G transmission, etc

3. Application layer: database management, platform construction, etc

4. Display layer: Web page display, BI data large screen, mobile app, etc

At present, across the country, some enterprises and projects have been slowly building smart engineering platforms. Due to many types of work, complex processes, more equipment applications and labor-intensive personnel, the risk has increased. For a project, if you want to do a good job in the smart engineering site, instead of blindly following the trend, you should not be all but fine. The first thing to be solved is to effectively understand the risk sources of the project. Of course, the project has some specific risk sources, as well as some risk sources with their own characteristics. The risks are determined according to risk identification, such as personnel safety management risk, tower crane equipment safety risk, power consumption risk in living area, fire safety risk and foundation pit risk, The risk of falling objects from height is divided into corresponding modules according to the determined risks. After building and supporting corresponding intelligent modules, such as real name management system, tower crane intelligent monitoring system, video monitoring system, power safety monitoring system, dormitory smoke sensing system, foundation pit detection system, environmental monitoring system, etc., these module systems are integrated into the platform end, It has completed its own and practical intelligent management platform system.
