Embodiment 2
Fig. 2 is the method flow diagram provided by the embodiment of the utility model for searching the source of atmospheric pollution.As shown in Fig. 2, described
Method the following steps are included:
Step 210, according to first time interval, point is controlled in state, the monitoring modular sample gas response value, and to described
Gas reaction value is handled, and AD value is generated.
The monitoring modular is monitoring modular described in above-described embodiment 1, and specific structure is in above-described embodiment
In be described, details are not described herein again.
First time interval can be set as needed, and first time interval is smaller, and in certain time, the data of sampling are got over
More, the accuracy of subsequent corresponding diagram is also higher.
Sensor in monitoring modular is available to gas reaction value, which is voltage value, AD converter
The voltage value is handled, AD value is generated.For example, first time interval can be 1 second, then in one minute, it is collected
Gas, for example the response value of CO is just 60, correspondingly, other gases, such as SO2、NO2、O3, PM2.5, PM10 etc., also for
60.Multiple response values of each gas are converted to digital signal by AD converter.
The precision of AD converter is 16 in this monitoring modular, i.e., the response value (current value) of gas is by low noise
Amplifying circuit is converted into voltage value, and the AD value of 0-65536, (0-65536 corresponding voltage are then converted into through 16 AD conversion chips
0-4.096V), the reference voltage that AD converts chip is 4.096V.For example, it is 0.1/4.096*65536 that 0.1V, which is converted into AD value,
=1600, every 1 AD value corresponding voltage value of variation changes 1/65536*4.096V=0.0000625V, i.e. biography in monitoring modular
Sensor voltage has faint variation, this AD converter also can detecte out.
Step 220, the AD value is sent to server by the monitoring modular, wherein is also stored in the server
The gas concentration value that first equipment of moment state control point uploads.
By communication module, AD value is sent to server.Meanwhile also to sample gas dense for the first equipment in state's control point
Angle value, the gas concentration value and AD value are one-to-one on a timeline.
First equipment is the atmospheric monitoring equipment of state's control point.The sample frequency and monitoring mould of first equipment of state's control point
The sample frequency of block is in principle, it should be set as synchronous, if asynchronous, can be calibrated in time.
Gas concentration value, such as CO, SO2、NO2、O3Etc. every kind gas all has 60 concentration values.
Step 230, the server gives birth to the multiple AD values and the corresponding gas concentration value in certain time
At corresponding diagram.
By taking the deep learning of CO sensor as an example, it is assumed that known a certain moment T0, the gas concentration value that point CO is controlled in state are
The AD value of N0, the CO of monitoring modular upload server are AD0.
The gas concentration value that point CO is controlled in T1 moment state is N1, and the AD value of CO is AD1；
The gas concentration value that point CO is controlled in T3 moment state is N3, and the AD value of CO is AD3；
The gas concentration value that point CO is controlled in Tn moment state is Nn, and the AD value of CO is ADn；
At this point, server according to above-mentioned gas concentration value and AD value Software on Drawing at table, and forming curves, the AD of record
Value and gas concentration value are more, and monitoring modular learns deeper.
Step 240, the monitoring modular obtains the address information of first position, and the first gas for sampling first position is anti-
It should be worth, and the first gas response value is handled, generate the first AD value.
GPS chip in monitoring modular obtains the address information of first position.
Step 250, the address information of the first AD value and the first position is sent to described by the monitoring modular
Server, the server determine the first gas concentration value of the first position by searching for the corresponding diagram.
The position for needing to detect, for example be to arrange that small-sized atmosphere environment supervision equipment (contains this Shen in city multiple regions
Please in monitoring modular), for example, gridding can be taken to layout, pass through every kind of gas concentration of the upload of every equipment of analysis
The height of data, in conjunction with wind speed and direction, passes through the host computer in server to carry out judging the height of corresponding region gas concentration
Drawing of the software to data judges pollution sources from which place to judge which regional pollution object concentration is higher.
Monitoring modular is first placed on state's control point as a result, and carries out a deep learning, i.e. the server gas that uploads monitoring modular
AD value and current gas concentration corresponding record are got up, and by Software on Drawing at table or curve, are learnt 1-2 days, it will are obtained big
The corresponding data of amount.Monitoring modular is placed on to the position for needing to detect, then the anti-gas for looking into monitoring modular upload of server
AD value may know that current location is tested the corresponding gas concentration value of gas.
After learning to complete, after sensor takes other places aging 24 hours, it is still uploaded to server A D value, is taken at this time
Business device can calculate concentration corresponding to current AD value, similarly, in monitoring modular according to the table or curve learned before
SO2、NO2、O3Sensor is also the same.
The monitoring modular of the lookup source of atmospheric pollution in the application, using the method for deep learning, than declaring out on the market
Factory is the module of concentration value, and stability, reliability, the accuracy of measured value want high.Because of such mould mostly
2-3 point is only demarcated before block factory, and monitoring modular passes through after deep learning, server has recorded a large amount of data of module,
Reach several hundred or even thousands of a points, the monitoring modular of deep learning is undoubtedly more accurate.After having the application of the method, it is possible to reduce
Operation cost is saved in capital investment of the enterprise to optical device.
Study by each module Jing Guo depth and then module in a manner of gridding cloth to each position, as
Neural contact one by one equally forms neural network, after server receives big data, to every kind of each position gas
Concentration data is analyzed, not only can be to the monitoring of every kind of each position gas concentration, but also can find pollutant sources
Position, the method are also called neural network algorithm.
The method in the lookup atmosphere pollution source, input cost is low, provides more acurrate and stable data, solves dirt
Dye source is difficult to the problem of searching.
It should be noted that the server in the application, for the server with computing capability, accordingly it is also possible to be referred to as
For terminal.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, these modifications or improvements on the basis of without departing from the spirit of the present invention, belong to the utility model and want
Seek the range of protection.
