Described curve map can see in the 5th to the 8th time in sampling period, and when vehicle takies road time showed increased, and PM2.5 content and content of sulfur dioxide remain unchanged substantially in the air.So can judge motor-vehicle tail-gas is not the source of causing atmospheric pollution herein, this moment, the related management personnel need may cause the pollution source of atmospheric pollution to investigate to other.This place wind speed scale is lower simultaneously, belongs to the light air rank, and the degree of polluting by the wind-force diffusion can be very not big, in time this ground contamination administered, just the effectively aggravation of contamination containment degree.

Be analyzed in conjunction with Fig. 5 b, the corresponding concrete data of Fig. 5 b are as shown in the table:

Described curve map can see in the 5th to the 8th time in sampling period, and when vehicle takies road time showed increased, PM2.5 content and content of sulfur dioxide are also grown simultaneously in the air, and the amplification large percentage.So can judge motor-vehicle tail-gas is the source of causing atmospheric pollution herein.Consider in conjunction with wind speed and direction simultaneously that this moment, wind direction was by north, and wind speed scale is higher, belongs to the strong gale grade, the pollution meeting is comparatively fast propagated by wind-force.Need the security personnel to hurry to the scene this moment, evacuates vehicle, reduces the pollution level of pollution source.Direction security personnel by north at this surveyed area should take to pollute the precautionary measures in advance simultaneously.

The present invention can detect the content of PM2.5 in the air in real time, the content of sulphuric dioxide, calculate current wind speed and direction, can also detect vehicle occupation number amount on the current time road accurately, and these are analyzed the output time history plot, thereby tail gas in the time of can quantitatively drawing the motor vehicle operation, wind speed, wind direction is to the atmosphere environment impact degree, improve the decision maker for urban traffic environment and take the corresponding measure foundation that offers precise data, and then can be accurately by the air-polluting degree is come Vehicular behavior is effectively supervised.

Simultaneously, the present invention also is provided with warning function, the PM2.5 content alarm threshold value that also comprises storage in the PM2.5 content QPj that sends by the more described PM2.5 sampling processing modules 31 of comparing unit 102 and the storage unit 101 among the described step S3, alarm unit 103 warnings when described PM2.5 content QPj surpasses described PM2.5 content alarm threshold value; Content of sulfur dioxide QE by comparing unit 102 more described sulfur dioxide treatment modules 32 transmissions _jWith the content of sulfur dioxide alarm threshold value of storage in the storage unit 101, as described content of sulfur dioxide QE _jAlarm unit 103 is reported to the police when surpassing described content of sulfur dioxide alarm threshold value.

The standard of domestic current is that the air quality index of the PM2.5 correspondence of 75 micrograms/cubic meter concentration is 100, namely is higher than 75 for not up to standard.It is 75 microgram/cubic meters that the present invention preferably arranges PM2.5 pollution index threshold value.The National Environmental quality standard is stipulated simultaneously, and residential district sulphuric dioxide daily mean of concentration is lower than 0.15 milligram/cubic metre, and mean annual concentration is lower than 0.06 milligram/cubic metre.Preferred sulphuric dioxide alarm threshold value is 0.15 milligram/cubic metre among the present invention.

Adopt the above embodiment of the present invention can draw the content of PM2.5 in a certain area and content of sulfur dioxide and vehicle and take time, the wind speed of road, the relation of wind direction, whether the pollution source that can obtain this area intuitively are the tail gas of motor vehicle emission.If it is very little to the content influence of the content of PM2.5 and sulphuric dioxide according to the monitoring of above-mentioned data being found vehicle takies time of road and wind speed and direction, then the decision maker can go to search other possible pollution sources, and finally formulates the scheme of polluting of administering according to pollution cause.

Obviously, above-described embodiment only is for example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being extended out thus or change still are among the protection domain of the invention.
