Description
Technical field
The present invention relates to a kind of air fine particles numeric value display method.
Background technology
Existing PM2.5 numerical value display mode is that PM2.5 detectors output signal to high in the clouds, and high in the clouds is real-time detector data
It is pushed to display giant-screen（Such as the display screen of school）Or the mobile terminal of user is sent to by network（Such as the shifting of parents of student
Dynamic terminal）, the PM2.5 numerical value of display is the actually detected numerical value at current detection moment, the deficiency that such a display methods is present
It is in the influence that can not objectively respond the air quality of interior well to health, people's interior incoming call for a period of time
PM2.5 total amounts just have a direct impact to health, such as one room does not have personnel's air quality difference when interior not interfere with human body
Health, personnel carry out air cleaning before entering room, and personnel are to start to have breathed air into room, and air quality is protected always
Hold outstanding, when entering house door is opened in room, instantaneously might have dirty air entrance, but PM2.5 numerical value now can not be true
Ground reflects influence of the IAQ to health, easily causes user to the unnecessary worry of IAQ, especially
It is when being used to monitor classroom's air quality, it is easier to cause parents of student to judge the overall air of school according to instantaneous value
Quality, causes unnecessary worry, and then may interfere with the normal order in education of school.
The content of the invention
, can be more objective, anti-exactly present invention aims at a kind of air fine particles numeric value display method is provided
Reflect influence of the air quality to health.
Realize the technical scheme of the object of the invention：
Real-time detector data is sent to cloud server by a kind of air fine particles numeric value display method, PM2.5 detectors, its
It is characterised by:Real-time detector data is sent to cloud server by PM2.5 detectors by network, and cloud server is according in real time
Detect that data calculate current PM2.5 and show numerical value, current PM2.5 is shown that numerical value is sent to display by cloud server by network
Giant-screen or mobile terminal.
Further, cloud terminal server obtains current PM2.5 and shows numerical value, number by calculating PM2.5 moving averages
It is worth formula as follows,
Dt=(At+At-1+At-2+At-3+ ...+At-n-1)/n,
In formula, Dt represents the PM2.5 numerical value currently shown；N represents number at the time of rolling average；At represents the current detection moment
Actually detected value, At-1 represents the actually detected value of preceding 1 detection moment；At-2 represents the actually detected value of preceding 2 detection moment,
At-3 represents the actually detected value of preceding 3 detection moment；Before At-n-1 is representednThe actually detected value of -1 detection moment.
Further, when in At, At-1, At-2, At-3 ... in At-n-1, when At values are minimum, then Dt=At, while by At
It is worth and calculates starting point as new moving average, i.e., next detection moment PM2.5 shows that numerical value is
Dt i+1=（At i+1+At i+1-1）/ 2, in formula, Dt i+1For the PM2.5 show values of next detection moment, At i+1For next detection
The actually detected value at moment, At i+1-1=At；
Further, the time interval of each detection moment is identical.
The device have the advantages that：
PM2.5 detectors of the present invention will detect that signal is sent to cloud server by network, and cloud server is according to detection number
Numerical value is shown according to current PM2.5 is calculated, current PM2.5 is shown that numerical value is sent to display giant-screen by cloud server by network
Or mobile terminal；Cloud terminal server obtains current PM2.5 and shows numerical value, due to display by calculating PM2.5 moving averages
Be PM2.5 moving averages, can more objective, influence of the reflection air quality to health exactly because really
Influence healthy is that the total amount of thing is stained in incoming call in a period of time, and then avoids the unnecessary worry of user.
The present invention is when in At, At-1, At-2, At-3 ... in At-n-1, when At values are minimum, then Dt=At, while At values are made
Starting point is calculated for new moving average, i.e., the present invention further takes minimum starting point rolling average value-based algorithm, carried out
The display of PM2.5 numerical value, can more objectively reflect influence of the air quality to health, it is to avoid user is to air quality
Produce unnecessary worry.
