Background and challenges
The construction industry is an important material production sector and one of the pillar industries of China's national economy. It plays an important role in improving living conditions, improving infrastructure, absorbing labor employment, and promoting economic growth. At the same time, the construction industry is also a high-risk industry with frequent accidents. In recent years, with the high attention and joint efforts of the competent authorities of the state, local governments and industry bodies at all levels, safety accidents in construction and construction have decreased year by year, and the quality level has been greatly improved. With the continuous advancement of urbanization, the scale of construction projects will also continue to expand, and the quality and safety of building construction cannot be taken lightly.
How to strengthen construction site safety management, reduce the frequency of accidents, eliminate various illegal operations and uncivilized construction, and improve the quality of construction projects will still be an important research topic before government departments at all levels, industry professionals and scholars.
In view of the current backwardness of safety supervision and preventive measures, the level of informatization of construction enterprises in the country is still low, and informatization has not yet been deeply integrated into the core business of production safety. It is urgent to use information technology to conduct "intelligent" supervision of construction production safety Through the construction of a comprehensive intelligent construction site safety management system, the company will further implement the responsibility for corporate safety supervision, improve the remote management level of the government and enterprises on the project site, and speed up the processing of potential safety hazards at the project site. The government has promoted enterprises to improve the construction of the Internet of Things through the introduction of corresponding regulatory documents, and further improved the level of security supervision through this system. Through the government's overall planning, coordinate the various business management departments, center on the safety supervision system, take the Internet of Things technology as the technical means, closely integrate the scientific and technological strength and the safety supervision system, and establish a comprehensive provincial-prefecture-level emergency management agency to achieve Institutional innovation can deal with all kinds of incidents in the field of production safety in a unified manner.
建筑工程安全质量物联网系统主要由信息采集层、网络接入层、网络传输层、信息存储与处理层组成，采用先进的物联网技术，将移动执法终端、施工升降机、塔式起重机作业产生的动态情况、工地周围的视频数据、混凝土和渣土车位置、速度信息及时上传给综合管理平台。 Pilot Guard's construction engineering safety and quality Internet of Things system is mainly composed of information acquisition layer, network access layer, network transmission layer, information storage and processing layer. Using advanced Internet of Things technology, mobile law enforcement terminals, construction elevators, and tower cranes are operated. The generated dynamic situation, video data around the construction site, the position of concrete and muck trucks, and speed information are uploaded to the integrated management platform in time. The integrated management platform integrates various subsystems and performs alarm linkage and other processing. Management departments at all levels can timely and accurately understand the status of the construction site, which will effectively improve the efficiency of project management and site management.
The system will construct comprehensive intelligent management measures for the safety of construction sites covering three levels of linkages of provinces, cities, counties, and project sites. According to the principle of authority setting and hierarchical management, the Provincial Construction Department, Municipal Construction Bureau, Construction Engineering Safety Supervision Station, and District and County Construction Bureaus, security supervision sub-stations, enterprises, and supervision departments can share information within their own authority.
Aiming at massive data, the system adopts the core idea of cloud computing, uniformly manages and dispatches a large number of computing resources connected by the network, and forms a computing resource pool to serve users on demand.
Digital Quality Safety Supervision Integrated Management System This system takes engineering as the core, tracks and records the entire project's basic information, personnel distribution, law enforcement records, etc., and finally outputs various demand reports.
The system can meet the internal office requirements of the competent government department, gradually realize the requirements of paperless office, and realize business applications such as comprehensive business management of construction sites, mobile law enforcement, remote supervision of site construction, management decision-making, external network information services, and inspection management.
Construction site visualized remote management system
工地可视化远程管理系统可实现以下系统价值： The visualized remote management system of the Pilot Guards site can realize the following system values:
Ø Know the real-time situation of the construction site in time, ensure the quality of project implementation and personnel safety, and eliminate the hidden dangers in time;
Ø Real-time check whether the safety precautions at the construction site are in place, such as the safety net setting of the building, the front-line protection of the construction worker's work surface, the wearing of construction workers' hard hats, the installation of external scaffolding and floor bamboo scaffolding, cable wind rope fixing and Use, installation and use of hanging baskets, protection of the inlet of the hanging plate and the floor unloading platform, installation and operation of tower cranes and hoists;
Ø Can remotely manage regional or national subordinate construction sites in a unified manner, avoiding frequent on-site supervision and inspection by manpower, and saving management costs;
Ø When abnormal conditions and emergencies occur, you can report the alarm in time to remind management personnel to deal with it in a timely manner;
Ø For the places where safety precautions are not in place during the construction process, the construction unit can be notified immediately to make on-site rectification, and the rectification effect can be checked in time;
Ø Strengthen the civilized construction management of construction sites, mainly aimed at construction site enclosures, stacking of building materials, temporary construction sites, fire protection, anti-theft, construction signage, etc.
在塔式起重机安全监控管理系统中，通过高精度传感器采集塔机的风速、载荷、回转、幅度和高度信息，控制器根据实时采集的信息做出安全报警和规避危险的措施，同时把相关的安全信息发送给服务器，塔机的监管部门可通过客户端查看到网络中每个塔机的运行情况。 Tower crane safety monitoring and management system In the tower crane safety monitoring and management system, the wind speed, load, rotation, amplitude and height information of the tower crane is collected through high-precision sensors, and the controller makes safety alarms and avoids dangers based on the real-time collected information. At the same time, the relevant safety information is sent to the server, and the tower crane supervision department can view the operation of each tower crane in the network through the client.
In the group tower solution, the tower crane and the tower crane use WSN for real-time communication, so that based on the single tower solution, the position information between the tower cranes can be obtained, and the problem of collision between the towers .
