With the development of modern construction technology, a large number of high-altitude tower cranes are needed in real estate development. As the most important and iconic figure on construction sites, the concept of safe production of tower cranes has been deeply rooted in people's minds, and people's requirements for safe production are getting higher and higher. In the construction industry where accidents are frequent, how to ensure the personal safety of construction workers and the preservation of construction materials, equipment and other property on the construction site are the top priorities of construction units.

Due to the limitations of the construction environment, the imperfect safety management of equipment and materials and the weak self-protection awareness of some employees, criminals have been provided with opportunities to take advantage of. In order to further improve the safety management of construction sites, the introduction of monitoring technology into construction sites has become the first choice for many construction units. Due to the particularity of the monitoring environment, it is difficult to wire construction sites. Wireless monitoring has its own advantages of high flexibility, strong scalability, and simple maintenance, and is widely adopted by many construction engineering companies.

Driven by the macro-economy, construction companies are now rethinking the way of communication and management with the site with an unprecedented attitude. The emergence of wireless video communication products has brought people a brand new video communication experience, which truly transcends time and space and makes people feel as if they are in a certain place. Our wireless video communication products are positioned for small and medium-sized enterprises related to outdoor construction, such as architectural design institutes, Party A, civil construction parties, road and bridge construction, supervision units, etc. These types of companies will gain huge commercial and personal value by using wireless video communication.

Why choose wireless video communicationThe most convincing reason is the basic demand of construction companies for face-to-face on-site communication. Other types of methods (such as telephones, cameras, intercoms, etc.) cannot reproduce the process of real on-site communication and communication management. The need for communication management must be combined with other real-time video communication transmission tools to fully understand each other's meaning and make projects and decisions go smoothly. The problem now is: in today's fast-paced environment that requires timely decision-making, sometimes it is inefficient to go to the site in person or even impossible to come to the site, but if you can't come, the risk is too great.

At the same time, strengthening remote communication and management on site is also necessary to improve the competitiveness of enterprises. The main reason for competition is that construction units need to surpass their core competitiveness and achieve efficient operation. The innovation ability and refined management level of enterprises are the main aspects of core competitiveness. The use of wireless remote video communication products can make better decisions in time and track the progress of projects more closely. The ability of enterprises to reduce risks caused by wrong decisions, inadequate management or lack of communication is greatly improved.

System design points

As we all know, the safety of foundation pits and slope support, formwork engineering safety, "three treasures" and "four mouths" protection, scaffolding safety and civilized construction at construction sites are the basic requirements for safe production. However, in quite a few construction sites, some construction units unilaterally pursue high profits, disregard the requirements of design specifications, and reduce safety standards from time to time, leaving safety hazards. In order to ensure the construction safety of construction projects, the traditional supervision method relies on safety management personnel to conduct in-depth inspections on the construction site, but due to limited manpower and low efficiency, it can no longer adapt to the new situation of increasing urban construction efforts in recent years. Therefore, strengthening the safety supervision means of construction sites and improving the level of safety production supervision have become the primary and urgent tasks facing the construction safety supervision department. The use of wireless video monitoring system, real-time supervision of multiple construction sites distributed throughout the city through computer screens, not only reduces the work intensity of supervisors, but also strengthens the regulation and supervision of construction administrative departments and regulatory agencies, and improves work efficiency. According to different construction stages, effective monitoring is implemented on the construction site of the construction site.

1. Foundation stage: Since the mid-1980s, the number of high-rise buildings in cities has increased, and how to solve the safety problems in foundation construction has become increasingly prominent, especially the collapse accidents caused by foundation pit excavation and manual bored pile construction, which have been included in the special governance content of the Ministry of Construction. In view of the characteristics of the foundation construction stage, the system has set up monitoring points for safety precautions.

2. Ground construction stage: During the ground construction stage, the building is open all around, the working surface is wide, there are many construction workers, and the sub-projects are often cross-operated. All kinds of safety precautions must be carefully considered and implemented. To this end, the remote safety monitoring system has set up various monitoring points, including "three treasures", "four openings" and formwork support operations. On the main working surface, such as floor operations, the wireless video monitoring system automatically detects and identifies the wearing of safety helmets by construction workers (the recognition rate is over 90%), and provides various safety information to relevant units in a timely manner.

3. High-rise operations: The wireless video surveillance system is designed to focus on the characteristics of high-rise operations, especially safety nets, safety helmets, scaffolding, guy ropes, hanging baskets, hoisting tray feed ports, floor unloading platforms, tower cranes, etc., to strengthen safety monitoring of high-rise construction and take precautions before it happens.

4. Civilized construction inspection: Whether the civilized construction measures are implemented in place not only affects the working environment and the appearance of the city, but also indirectly and directly involves the safety of the construction site and construction workers. For this reason, the wireless video monitoring system also has targeted monitoring points for civilized construction on the construction site, all with the aim of implementing safety work.

System features:

According to user needs, the system fully considers the actual application situation on site. The front end of the monitoring adopts digital wireless video transmission equipment ( SF-2414CH ) which can directly connect to the digital high-definition camera. The wireless transmission method will greatly improve the flexibility and speed of the on-site layout, avoiding the problem of large-scale mechanical equipment crushing the traditional monitoring line. At the same time, the transmission between the monitoring point and the receiving point is relatively straight, avoiding the problem of winding construction.
