(A) the practical application of remote safety monitoring system in construction sites
As we all know, the safety of foundation pit and slope support, formwork engineering safety, "three treasures" and "four mouths" protection, scaffolding safety and civilized construction are the basic requirements of safe production. However, in quite a number of construction sites, some construction units unilaterally pursue high profits, regardless of the requirements of design specifications, and problems of lowering safety standards occur from time to time, leaving security risks. In order to ensure the construction safety of construction projects, the traditional supervision method relies on on on-site inspection by safety management personnel, but it has been unable to adapt to the new situation of increasing urban construction in recent years due to limited manpower and low efficiency. Therefore, it has become the primary and urgent task of the construction safety supervision department to strengthen the means of safety supervision on the construction site and improve the level of safety production supervision.
Based on the above understanding, Xiamen Construction Engineering Quality and Safety Supervision Station began to establish a remote safety monitoring system for construction sites in 2000. Using video remote monitoring and real-time monitoring of many construction sites distributed all over the city through computer screens, not only reduces the work intensity of supervisors, but also strengthens the supervision and supervision of construction administrative departments and regulatory agencies, and improves work efficiency.
In recent years, the system has widely listened to the opinions and suggestions of construction administrators, site construction managers and supervisors, and continuously improved the system performance, so that it can effectively monitor the construction site with different monitoring methods according to the characteristics of video monitoring and different construction stages.
1. Foundation stage: Since the mid-1980s, there have been more and more high-rise buildings in cities, and how to solve the safety problems in deep foundation pit construction has become more and more prominent, especially the collapse accidents caused by foundation pit excavation and manual digging pile construction have been included in the special treatment content of the Ministry of Construction. According to the characteristics of foundation construction stage, the system sets the monitoring focus of safety precautions.
2. Ground construction stage: When entering the ground construction stage, the buildings are open around, the operation area is wide, there are many construction workers, and various sub-projects often cross-operate, so all kinds of safety precautions must be considered comprehensively and put in place. For this reason, the remote safety monitoring system has set up various monitoring points, including "three treasures", "four ports" and template support operations. When working on main working faces such as floors, the remote safety monitoring system automatically detects and identifies the wearing conditions of construction workers' helmets (the recognition rate is over 90%), and provides all kinds of safety information to relevant units in time.
3. Working at heights: According to the characteristics of working at heights, the remote safety monitoring system has set up various monitoring points, especially safety nets, helmets, scaffolding, cable ropes, hanging baskets, hanging basket entrances, landing unloading platforms, tower cranes, etc. , so as to strengthen the safety monitoring of high-rise buildings, nip in the bud.
4. Civilized construction inspection: Whether civilized construction measures are put in place not only affects the working environment and city appearance, but also indirectly and directly affects the safety of the construction site and construction personnel. Therefore, the remote safety monitoring system also set up civilized construction monitoring points in the construction site in a targeted manner, with the aim of implementing safety work.
(B) the significance of the application of remote safety monitoring system in construction sites
Remote safety monitoring system integrates computer network and communication technology, video compression technology, decision support system and other modern high-tech, which is of great significance to strengthen the safety production management of construction sites.
First of all, all kinds of data information obtained by the system through remote monitoring are processed and analyzed, so that the working mode of safety supervision departments and supervision units changes from traditional on-site supervision to remote video supervision; Through the remote video automatic identification and monitoring alarm system, it can be further transformed into mobile supervision. Really realize supervision and management at any time (at any time) anywhere (anywhere). It has achieved a revolutionary leap in the construction project supervision mode. So as to greatly improve the supervision level and work efficiency of construction safety production. In the past, the safety of construction projects could only be controlled by functional departments on-site inspection, which was random and uncertain. In order to catch up with the construction period or reduce the cost, the construction unit often ignores the safety in production. After realizing remote video automatic identification and monitoring alarm, it is equivalent to having an "electronic police" in safety production and a pair of "clairvoyant eyes-smart eyes" for safety supervisors, so that safety supervision departments can grasp the safety situation of the construction site at any time and find it in time.
Secondly, the system adopts data encryption technology, firewall technology, disk sharing technology, key component redundancy technology and other related authentication technologies, and its security and reliability are fully guaranteed.
Third, the system should fully consider the reality of the construction site and the current situation of computer applications in various departments, and strive to improve the practicability, adaptability and flexibility of the system in implementing remote monitoring while ensuring the realization of various functions of the system, so as to meet the different needs of safety supervision work to the greatest extent.
To sum up, the application of remote safety monitoring system in construction site has many advantages, such as multifunction, high efficiency, good safety and reliability, practicality, adaptability and flexibility. Therefore, since Xiamen Construction Engineering Quality and Safety Supervision Station established the remote safety monitoring system, it has been praised by leaders, experts and peers of the Ministry of Construction and the Provincial Construction Department for many times. However, because the application of remote safety monitoring system in the construction site is still a new thing, especially the development and establishment funds of the system, there is no stable source of funds for monitoring the construction site, which affects the wide promotion of remote safety monitoring system; On the other hand, the system itself needs to be further improved and optimized. The main objectives are as follows:
1, realize the standardization of safety supervision information and management, and make information exchange faster and more accurate. Including information coding, business process standardization, scientific decision-making informationization, etc. In order to reduce the misunderstanding caused by the uncertainty and fuzziness of information and reduce the information lag caused by disorderly management;
2. Use advanced means such as multimedia, call center and Internet to provide efficient, convenient and high-quality services and establish a good image of functional departments;
3. Establish a building safety data center to realize the intelligence of safety supervision. Including on-site real-time data automatic processing, enjoying all kinds of data, using computers to automatically count all kinds of reports, displaying all kinds of indicators, and providing timely and accurate information for management.
