With the improvement of China's economic and social development level, the construction industry has developed rapidly. However, safety issues in construction operations have always been severe, and the frequency of accidents in the construction industry has ranked among the top in various industries in the country. Therefore, safety management is a very important factor in ensuring construction safety during the construction process.

In recent years, with the rapid development of the intelligent industry, large screen monitoring systems have broken the simulation structure of the past "closed-circuit television system", achieving real-time, vivid, and realistic reflection of the monitored object's image, becoming an extremely effective tool for people to monitor and control in modern management. Its application has gradually spread to various industries and has a unique role in modern architecture. Specifically, it can improve the level of information management for safety production, strengthen the management of safety protection on construction sites, monitor the implementation of safety production measures in real time, ensure that the entire construction process is under control, and thus eliminate safety hazards in a timely manner.

The role of large screen monitoring system in ensuring construction safety

1、 The necessity of applying large screen monitoring systems to construction sites. In some construction sites, some construction units often neglect safety production in order to meet deadlines or reduce costs, leaving safety hazards. In order to ensure the construction safety of construction projects, traditional supervision methods are inefficient and can no longer adapt to the new situation of increasing urban construction efforts in recent years. Strengthening the safety supervision measures of construction sites has become the primary and urgent task facing the construction safety supervision department. By adopting a large screen monitoring system, the construction site is monitored in real-time through the large screen, which not only reduces the workload of regulatory personnel, but also strengthens the regulation and supervision efforts, and improves work efficiency.

2、 The inevitability of applying the principle of large screen monitoring system to construction safety management. Through the large screen monitoring system, construction enterprises can remotely control and view the construction sites where the monitoring system is installed in their own enterprises in real time; The construction site project department, project construction unit, and supervision unit can operate and use large screen monitoring equipment for real-time on-site supervision. It is a beneficial supplement to the traditional management mode of current security work.

3、 Strengthening the installation technology requirements of large screen monitoring systems to enhance the effectiveness of safety supervision. Through the reasonable layout of construction sites, efforts are made to improve the practicality, adaptability, and flexibility of the system in implementing remote monitoring, in order to meet the different needs of safety supervision work to the maximum extent possible

1、 The fierce price competition in the LCD splicing market

Since entering the security application field in 2009, LCD splicing large screen products have been quickly favored by the explosive demand in the security market. Due to the low threshold for product entry into the market, all monitor manufacturers have rushed forward, and even a large number of LCD panel traders have joined in; In addition, splicing large screen products are mainly applied by government administrative institutions and large industrial and mining enterprises, and generally adopt open bidding methods. For a time, price seems to be the only "variable" in the competition. These two reasons have led to the fierce situation of the "price war" of LCD splicing screens. It is reported that in 2013, over 90% of LCD splicing screen manufacturers generally had a factory gross profit margin of less than 20%.

IILCD splicing large screenThe product has a serious situation of extensive operation, and the quality is uneven:

1. DID LCD panel: The core component of the LCD splicing large screen is the DID LCD panel. At present, the DID LCD panels used for splicing in China are mainly produced by Samsung in South Korea, accounting for about 80% of the market share, followed by LG, SHARP, AU and other brand manufacturers. Due to the extremely high production process and technical requirements of DID industrial LCD panels, it is impossible to produce and assemble them domestically. Therefore, all LCD splicing manufacturers publicly claim that the DID LCD panels used are Samsung's original products; The using units and users also accept based on their trust in the Samsung brand. In fact, this is not the case: due to the physical properties of liquid crystal atoms, it is inevitable for individual crystal atoms to form blind spots (i.e. bright spots, dark spots, or color spots) during the production process; Edge light leakage is also prone to occur during the assembly process. The quality standards for DID splicing LCD panels are generally divided into A, A, A -, and B specifications, collectively referred to as A specifications in the market. A standard screen shall comply with the international standard 3-3-5 (i.e. 10 pieces per package, with 3 pieces allowed to have dots, a maximum of 3 dots allowed for monochrome fields, and a maximum of 5 dots allowed for RGB full-color fields); B standard screen refers to panels with severe quality defects such as mild light leakage and wood pulling. In fact, screens of different specifications have different factory sales prices, usually with a difference of about 10%.
