In order to speed up the construction of Shenzhen’s smart city, promote the scientific and standardized management of construction projects, and improve the quality and safety of projects and the level of civilized construction, according to the "Notice of Shenzhen Municipal Housing and Construction Bureau on Strengthening the Management of Video Surveillance of Construction Projects in the City" (Shenzhen Construction Quality and Safety) [2011] No. 57) and "Shenzhen Construction Engineering Safety and Civilized Construction Standards" (SJG-46-2018) document spirit, our bureau decided to start the implementation of the video surveillance system for the city’s municipal management projects under construction on September 1, 2018 The special inspection work requires that all projects must be strictly followed and executed, including projects that have not been installed with video surveillance, projects that have been installed with video surveillance but do not meet the requirements of the standard, and new projects.
Shenzhen Aosen construction site dust online monitoring system complies with the relevant regulations of GB3096-2008 "Acoustic Environmental Quality Standard" and GB3095-2012 "Ambient Air Quality Standard", and has the China Environmental Protection Product Certification (CCEP), provincial (city) level Metrology Institute The issued measuring instrument form approval certificate (CPA), equipped with high and low dual monitoring heads, multi-directional monitoring of construction site dust conditions, real-time online monitoring of construction site TSP, PM2.5, PM10 parameters, while supporting wired, wireless broadband, 3G mode transmission High-performance, high-bandwidth, multi-function, outdoor professional-grade monitoring equipment. The equipment uses light scattering method for dust particle analysis technology, and is integrated with a mature noise monitoring module. The data curve is stable, easy to install, safe and stable. At the same time, the cloud is equipped with a dust pollution monitoring cloud platform, mobile phone APP, WeChat application terminal, and remote host computer client, which can seamlessly access the construction committee platform in real time.
1. Perception layer: pollution source online monitoring instrument, including particulate matter concentration monitor, meteorological five-parameter monitor, noise monitor and video monitoring machine, continuous and automatic online monitoring of particulate matter concentration, meteorological parameters, noise and live video; OSEN-YZ The particulate matter monitor can realize the real-time monitoring of the dust, and the data can be reported wirelessly.
2. Transmission layer: use wired, wireless, 3G/4G and other methods to transmit various monitoring data;
3. Platform layer: Data service cloud platform, relying on the data of the dust and noise monitoring platform of the construction site, conducts system analysis, provides cross-regional, full-time, multi-level data mining and comparison, and provides data support for scientific smog management;
4. Application layer: Client systems for different environmental protection bureaus and construction sites to realize real-time Web-based online monitoring of pollution source data, on-site image and video monitoring, pollution source exceeding alarms, and various management and statistical analysis for different management levels .
There are web-based real-time online monitoring of pollution source data, on-site image and video monitoring (including real-time control of front-end PTZ and monitoring machines), pollution source exceeding alarms, and various management and statistical analysis for different management levels.
Technical characteristics and advantages of the prevention and control plan for dust pollution in the construction of municipal foundation engineeringThe system is designed based on the demand for monitoring and management of dust pollution in urban construction sites. The technical characteristics and advantages are mainly reflected in the following four points:
(1) With CCEP and CPA dual certification, equipped with high and low dual monitoring heads, the monitoring terminal system system integrates TSP, PM10, PM2.5, temperature, humidity, wind direction and wind speed, atmospheric pressure, rainfall and other environmental parameters, 24 hours a day, 24 hours a day online continuous monitoring, providing air quality data of the construction site around the clock, and can automatically start monitoring equipment when the alarm value is exceeded, with multi-parameter, real-time, intelligent and other characteristics;
(2) Transmit and transmit data through the three major networks of sensor networks, wireless networks, and the Internet, and update real-time monitoring data quickly and conveniently;
(3) The cloud computing-based data center platform gathers monitoring data from different regions and at different periods of time. It has a large amount of storage space and can perform multi-directional and multi-temporal data statistical analysis, which is convenient for the management part to carry out work in an orderly manner. The construction site environmental pollution control standards accumulate data to promote long-term management of air pollution.
(4) The whole system adopts free modular combination, according to the need of unorganized pollution monitoring, different monitoring items can be flexibly added or reduced. At the same time, the free modular combination can be used at any time if the core sensor fails and does not need to be repaired. The sensor is replaced without affecting the normal operation of the whole equipment, which solves the problem of time-consuming and cost-consuming return of the whole machine to the factory when the traditional equipment fails
The advantages of the networkable dust video monitoring system:Shenzhen Aosen is a national high-tech enterprise, Shenzhen high-tech enterprise, and Shenzhen double soft enterprise. The products independently developed and produced by Aosen have been recognized by many national authorities, China Environmental Protection Product Certification (CEP), the People’s Republic of China Type Approval Certificate for Measuring Instruments (referred to as CPA), Quality Management System Certification, Provincial Quality and Technical Supervision Bureau Test report, municipal metrology institute calibration report, utility model patent certificate, computer software copyright registration certificate, etc. The self-developed OSEN-YZ dust and noise online monitoring system meets national standards, and the cloud is equipped with a dust pollution monitoring cloud platform. The mobile phone APP, WeChat application terminal, and remote host computer client can seamlessly access the construction committee platform in real time. Aosen looks forward to cooperating with you, the national hotline is transferred to 3752
