Embodiment Construction
[0031] The artificial smog monitoring system of the present invention includes a front-end box and a background computer, based on the digital camera in the front-end box to collect the image of the target object in a constant light source environment (abbreviated as "target image"), and the data transmission unit transmits the target image through the network Go to the background computer, and get the current haze measurement result by calculating the characteristic change rate of the target image.
[0032] For ease of understanding, the system and method of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0033] The artificial smog monitoring system of the present invention comprises the following hardware:
[0034] (1) Front box
[0035] See Figure 1~2 , the front box is designed as a breathable and opaque cuboid box, which allows the outside air to enter but prevents the outside light from entering through the doub...

Abstract
The invention discloses imitated artificial haze monitoring system and method. The imitated artificial haze monitoring system comprises a breathable and light-tight front-end box body and a background computer, wherein a target object, a constant light source, image collection equipment and a data transmission unit are arranged inside the front-end box body; the target object is a red and black checkerboard array picture; the constant light source is arranged at the top of the inner side of the front-end box body; the image collection equipment and the target object are oppositely arranged; the image collection equipment transmit data to the background computer through the data transmission unit; the background computer is used for computing the color characteristic, the shape characteristic and the texture characteristic of the target image, obtains the change rate of each characteristic relative to the corresponding characteristic of the target image in absence of haze, obtains haze indexes according to each characteristic change rate, and obtains haze concentration through a mapping function according to the haze indexes. Haze monitoring is achieved from a new angle, the imitated artificial haze monitoring system is low in cost, and easy to deploy, and overall haze monitoring of an overall area can be achieved. Thus, abundant information is provided for air pollution prevention and treatment.
Description
technical field [0001] The invention belongs to the technical field of air pollution prevention and control and haze measurement, and in particular relates to an artificial haze monitoring system and method. Background technique [0002] Traditional smog discrimination is done through manual observation and analysis combined with meteorological elements such as relative humidity. At present, there is an air pollution monitoring system based on a weather station, which is equipped with a moisture tester, a smoke turbidity meter, a black carbon monitor, an aerosol monitor, a visibility monitor, an organic carbon monitor, an elemental carbon monitor, a volatile organic Compound monitors, ultraviolet radiation meters, atmospheric stability monitors and other instruments can better realize the detection of PM2.5, PM10, black carbon, ozone, sulfur dioxide, nitrogen oxides, carbon monoxide, sulfate, nitrate, ammonium salt, Volatile organic compounds, particle size distribution, pa...
