May 10th "Temperature: 26 ° C, noise: 52 decibels, PM2.5: 73 ug / m3, PM10: 81 ug / m3, which appeared at 2 pm on May 7 at Xianglong Street, Xingcheng Chunxiao Phase II The real-time data on a screen in the construction site of the project site. In the next second, the data changes according to the site conditions. Originally, this is an environmental data monitor that is turned on 24 hours and can reflect PM2 in the construction site in real time. 5, PM10, temperature, humidity and other data. At the same time, there are 6 surveillance cameras distributed in the construction site, and the data and camera monitoring images of this monitor can be built in Changsha County Urban and Rural Planning and Construction Bureau video monitoring room within a few kilometers away. See it in real time.
According to the Changsha County Urban and Rural Planning and Construction Bureau, the county's construction site video surveillance and dust online monitoring system has been launched recently. At present, the dust monitoring data network of 18 construction projects has been integrated into the monitoring platform. In the future, if noise, dust, etc. are exceeded during the construction of the construction site, the supervisors will be able to know for the first time and deal with it promptly.
On the day when the PM2.5 exceeded the standard for the first time, in the remote monitoring room located in the Urban and Rural Planning and Construction Bureau of Changsha County, the reporter saw a large screen consisting of nine 46-inch LED LCD screens on one wall. The supervisors were working on the construction site through video. The construction site is monitored. Through this “Clairvoyanceâ€, 18 new projects and 46 construction sites connected according to the previous standards were scrolled online on the screen, and the site work site was unobstructed.
Tang Zhixing, the head of the Industry Planning Section of the bureau, told reporters that through monitoring, the situation of these sites can be clearly seen. The monitoring equipment installed on the site will be opened 24 hours a day, which can reflect the concentration and temperature of particulate matter in the construction site in real time. "You see, the PM2.5 and PM10 values ​​of this site are in the normal range. If a certain threshold is reached, it will alarm. We will inform the safety supervision station to request the project to be processed." Tang Zhixing pointed to one of the screens. Said the work.
To make up for the lack of manual inspection, the building materials are neatly arranged. Several construction workers are carrying out pile foundation construction in the foundation pit... The situation that the reporter saw at the site of the Xingcheng Chunxiao Phase II construction project was taken by the Industry Management Section of the County Urban and Rural Planning and Construction Bureau. The staff looked at it through monitoring. With this real-time monitoring system with “Clairvoyance†function, supervisors can grasp the situation of each project without having to be present in person.
Winning the blue sky defense war, construction site dust pollution control is one of the key points. In recent years, with the acceleration of economic development in Changsha County, a large number of projects have been settled in succession. These construction sites have also become the key monitoring places for environmental protection work. According to the requirements of the municipal government and the Municipal Housing and Construction Committee, there are more than 100 construction projects in Changsha County that need to establish and implement online monitoring of video surveillance and dust noise.
The construction sites are widely distributed, and the supervisors are limited. How to carry out effective supervision is the key and difficult point in the dust control work. “In the past, monitoring relied mainly on manpower to conduct inspections. Nowadays, there are more and more projects under construction in the county, and the distribution is more and more extensive. The original inspection methods have been difficult to cover and lack timeliness.†Changsha County Urban and Rural Planning and Construction Bureau Director Hu Chaoqin introduced that the online monitoring platform can make up for the shortage of manual inspections and facilitate information collection. At the same time, it can implement remote monitoring 24 hours a day, and the problems can be detected and dealt with in time.
At the same time, 150 reporters under construction can be monitored. It is known that 18 cameras have been installed in 18 networked project sites, which are located at the main entrance and exit of the construction site, the commanding height, the construction work surface, the construction site of major dangerous sources and the online monitoring system of dust. Ground. After being included in the online monitoring system, it can collect real-time particulate matter and noise parameters on the site, and timely control and control on construction quality, safe production, and civilized construction.
The hardware construction of the monitoring system can guarantee the simultaneous monitoring of 150 projects under construction, and the video storage is no less than 365 days. “By sharing big data, realizing municipal platforms, existing monitoring platforms, and public security, environmental protection, and administrative law enforcement departments, the relevant regulatory enforcement personnel can grasp the construction status and dust control of the construction site for the first time. Achieve accurate monitoring, precise management and precise supervision of construction sites."
