Problems solved by technology

The existing construction dust monitoring system is mainly composed of a video acquisition terminal, a dust concentration monitoring module, a controller, a communication module and a remote monitoring platform. The dust concentration monitoring module mainly uses the principle of light scattering to detect the dust in the air of the construction site. Concentration, in the process of detecting the dust concentration of the building construction site, the detection signal is greatly affected by environmental factors such as temperature, wind speed and wind direction, which may easily cause the detection signal to be out of balance, and the clutter frequency generated by the external light source will also affect the dust concentration. The signal processing of the sensor brings interference, causing deviations in the detection results and affecting the accuracy of system monitoring

Abstract

The invention discloses a building construction flying dust monitoring system based on big data. The system comprises a video acquisition terminal, a dust concentration monitoring module, a controller, a communication module and a remote monitoring platform. The dust concentration monitoring module comprises a dust concentration detection circuit, a temperature drift suppression circuit and an operational amplifier filtering adjustment circuit, and the dust concentration detection circuit comprises a dust concentration sensor used for detecting the dust concentration of a building constructionsite. A detection signal is primarily enhanced by an operational amplifier AR1, and then noise reduction is carried out on the amplified signal by using RC filtering, so that the interference of external high-frequency disturbance on a detection signal is reduced. The temperature drift suppression circuit and the operational amplifier filtering adjustment circuit are designed to perform analog circuit adjustment on an output signal of the dust concentration detection circuit, so that the detection signal imbalance caused by the external temperature is effectively avoided, the clutter frequency generated by an external light source is prevented from interfering the accuracy of a detection result, and the recognition capability and sensitivity of the system to the detection signal are greatly improved.

Description

technical field [0001] The invention relates to the technical field of dust monitoring, in particular to a building construction dust monitoring system based on big data. Background technique [0002] my country is in a period of rapid urban infrastructure development, and the dust generated by construction sites is one of the main sources of air pollution. Due to the limited number of personnel in the supervision department, it is impossible to go to various construction sites to inspect every day. Therefore, for many scattered It is undoubtedly an effective way to supervise the dust pollution of engineering construction to carry out remote online monitoring on the construction site, timely discover the construction site that violates the dust prevention requirements and has dust pollution and deal with it in time. The existing construction dust monitoring system is mainly composed of a video acquisition terminal, a dust concentration monitoring module, a controller, a commu...
