Application field of environment monitor for dust monitoring system The dust TSP automatic online monitoring system is a standard version of dust monitoring system focusing on dust and noise monitoring. It is suitable for office buildings, residential buildings, factories, warehouses, shopping malls, parks, museums and other buildings, as well as urban streets, Both sides of highways and other roads. It is expected that in the future, it will be used in some modern projects such as digital*, smart cities, wireless cities, and smart construction sites, and assume the important task of "environmental monitoring" in these projects. Application areas: Mainly applicable to construction sites, demolition sites, coal mines, industrial parks, communities, urban environments, residential quarters, etc. Sensor specifications: (1) PM2.5/PM10/TSP Measuring range: 0.001-10mg/m3 Accuracy: ±10% (2) Noise Measuring range: 30-130dB accuracy: ±0.3dB (3) Air temperature Measuring range: -40～60℃ Accuracy: ±0.2 (4) Air humidity Measuring range: 0～100% accuracy: 3% (5) Wind speed sensor accuracy: ±1m/s Starting wind: 0.2-0.4m/s Measuring range: 0-60 m/s (6) Wind direction sensor Measuring range: 0--360 degrees (0.4V, or 4MA corresponds to 0 degrees, north direction) Load capacity: less than 600 ohms, 250 ohms are generally recommended (7) Atmospheric pressure sensor Unit: mbar Measuring range: 500～1100mbar (ie 50～110Kpa) Working environment: -20 ～85℃ Measurement accuracy: 15 bits Features: Realize real-time online monitoring 24 hours a day. In order to provide accurate particle concentration information, multiple sensors can be connected and remotely transmitted to the large LED display. The alarm management is set, and when the limit is exceeded, a short message will be sent to the designated mobile phone to provide timely warning and improve the effectiveness of real-time monitoring. Temporary failures in the external power supply and communication system do not affect data collection. After the communication is restored, the delayed transmission can be automatically downloaded; permanent power failure will not lose the collected and stored data. Support real-time display data such as multi-size color LCD and LED outdoor display. (The outdoor display can be customized according to customer needs) Realize data storage management, graphical display of data at monitoring points, curve analysis, alarm statistics for over-limit and over-standard, etc., to provide a basis for decision-making by regulatory authorities. Data can be queried in real time through mobile phones, computers, and tablet clients. Dust from construction sites is sporadic and sudden. To achieve the effect of controlling pollution sources, what kind of monitoring methods are used is extremely important. "Currently, the monitoring methods we use still rely on manpower to conduct inspections in one place. This type of inspection is not only difficult to cover due to limited manpower, but also lacks timeliness. In addition, traditional human inspections still have inspection results that are mainly based on estimation, which is difficult Quantification and analysis have led to shortcomings such as insufficient scientific basis for corresponding punishments, which are no longer suitable for the new situation and new requirements of the current dust remediation work in Chengdu." Through the establishment of an online dust monitoring system, it is possible to track and monitor the dust emission status of construction sites in real time 24 hours a day, which is equivalent to installing a monitoring "eye" on the construction site; and the system can quickly process the returned data and monitor the excess The construction site with the scheduled emission value will give a real-time alarm and automatically send text messages to inform the site in time so that the person in charge can do the corresponding rectification work.
