At present, many construction sites still use monitoring methods that rely on manual inspection of each location; Due to limited manpower, this type of inspection is not only difficult to fully cover, but also lacks timeliness; In addition, traditional manual inspections still have shortcomings such as relying mainly on estimation of inspection results, which are difficult to quantify and analyze, resulting in insufficient scientific basis for corresponding penalties, and are no longer suitable for the new situation and requirements of dust control work in Chengdu.
If a construction site establishes a dust and noise monitoring system, it can track and monitor the dust emissions of the construction site in real-time 24 hours a day, which is equivalent to installing a monitoring "sky eye" on the construction site; And the system can quickly process the returned data, provide real-time alarms for construction sites that exceed the predetermined emission values, and automatically send text messages to inform the sites in a timely manner, so that the responsible person can carry out corresponding rectification work.
Construction site dust and noise monitoring systemSeveral details to pay attention to when choosing:
（1） Equipped with CCEP and CPA dual certifications, and equipped with high and low position dual monitoring heads, the monitoring terminal system integrates multiple environmental parameters such as TSP, PM10, PM2.5, temperature, humidity, wind direction and speed, atmospheric pressure, rainfall, etc. It is continuously monitored online 24 hours a day, providing air quality data of the construction site 24 hours a day. When the alarm value is exceeded, the monitoring equipment can be automatically activated, with multi parameter, real-time, intelligent and other characteristics;
（2） Transmit and transmit data quickly and conveniently through the three major networks of sensor networks, wireless networks, and the Internet to update real-time monitoring data;
（3） The cloud computing based data center platform gathers monitoring data from different regions and time periods, with massive storage space for multi-dimensional and multi temporal data statistical analysis. This facilitates the orderly development of management work and also accumulates data for establishing environmental pollution control standards for construction sites, promoting long-term management of air pollution.
（4） The entire system adopts a free modular combination, which flexibly adds or reduces different monitoring items according to the requirements of unorganized pollution monitoring. At the same time, the free modular combination can replace the sensors at any time without the need for repair in the event of a core sensor failure, without affecting the normal operation of the entire equipment, solving the problem of time-consuming and costly return of traditional equipment to the factory.
