Environment Noise and dust Video monitoring system in Construction Field
- 1. RJ-20 Construction Field Dust and Noise Monitoring System 1. Component: 1). Perception layer: Pollution Source Online Monitoring Device include Particulate Concentration monitor, Meteorological monitor, Noise Monitor and Monitoring Camera. The device can monitor the particulate concentration, meteorological parameter, noise and live video automatically and continually. 2). Transport Layer: It will transfer kinds of monitoring data by wire or wireless network, 3G, 4G, etc. 3). Platform Layer:
- 2. Data Service Cloud Platform will carry out systemic analysis, dig and compare cross-region, whole-time, multi-level data based on the monitoring data, so as to offer support for fighting haze scientifically. 4). Application Layer: Kinds of terminal platform can visit data by the monitoring system.Online pollution source data, on-spot pictures and videos, beyond index of pollution source warning, Statistic analysis of different management layer will come true by Web. 2. System Functions and Characters Functions: Monitoring kinds of pollution sources: Integrate noise monitor with dust monitor; Video multi-function: Video monitoring pictures will display noise and dust value; All weather and automatic work: 24 hours in whole year, and warn when device is damaged; Optional communication method: wire network, GPRS/CDMA/EDGA/3G/4G, operator exclusive network;
- 3. Extended meteorological parameter: temperature, humidity, wind speed, wind direction, etc can be added to our system, so as to reach comprehensive monitoring; Stainless steel case: Protection grade is IP65(stubborn, anti-dust, rust proof, moisture-proof) so as to adapt to severe industrial environment. System Character: Standard IP65 case, adaptable ability with all weather and complex environment; Work in normal: Relative humidity: 10%-90%, environmental temperature: -40℃-70℃ Monitor can be installed flexibly, permanent or semi-permanent is optional; 220 Volt, others can be OEM; Convenient wireless transfer, it can work once covered by mobile network; We can investigate and record measured data on the network management platform;
- 4. It can record, summarize, statistic, analyze, comment and publish information according to the requirements of the environmental management; It can draw noise time-space distribution graph, kinds of data report; It can calculate perceived noise level and effective perceived noise level(EPNL); It can analyze the dust particle number, convert statistic data: volume/mass; GPS software: it can measure the position of the noise monitoring end accompanied with the GPS unite and deposit the data in the data base; Independent systemic monitor will guarantee the system work stable and reliable. 3. Monitoring method and feature parameter Items Feature Parameter Noise Monitor Measuring Range: 30-130Db； Frequency Range: 20-12.5kHz； Maximum Error: 0.5dB； Frequency Weighting: A；
- 5. All weather outdoor sensor is up to <Environmental noise automatic monitoring system technical requirements>, GB/T 20441.4 measuring sensor Forth part: work calibration sensor specification; Data collection unit can collect and transfer data, which is used to control noise and dust monitoring system, collect and transfer data, etc. Manual Calibration is available; Microphone is installed on the top of the device so as to make sound calibration and daily maintenance easily; Noise signal will enter our system, at the same time, camera monitoring picture will indicate noise value. Dust Monitor Measuring Range: PM10. (PM2.5 and TSP monitoring item can be optional); Range: 0-10mg/m³; Minimum Testing Density: 0.001mg/m3; Flow Deviation of Sample: <±10%/24 hours or ±5%/24 hours; Working Power：DC Power(24V) or AC220V±10%; Collection, Storage and Transfer Module are used in the control of dust monitoring system, data record and transfer; Dust signal will enter our system, at the same time, camera monitoring picture will indicate dust value;
- 6. Relative error on flexibility and accuracy of dust monitor is up to <JJG846-93 Light scattering detector type digital dust verification regulation requirements>. Meteor ological Monitor Temperature: measuring range: -40～60℃; Accuracy: ±0.2℃； Humidity: measuring range: 0～100%; Accuracy: ±3%； Wind Speed: 0~40 m/s:; Accuracy: ±1m/s； Wind Direction: 360 degree; Accuracy: ±5%； Barometric Pressure: 300～1100mbar(namely 30～110Kpa); Accuracy: 15 numbers after dot； Installing bracket, distribution box, etc are included so as to install easily for end users.
