And a concentration value n when P is 2 (good health grade, score 90 points)2The concentration was determined using the upper limit of the standard. And n is to be0,n2And P2 is substituted for formula 1 to obtain PM2.5Corresponding constant C.
Similarly, referring to tables 3-9, the system utilizes N, respectivelyi、HCHOi、Oi、RHi、Ii、TiAnd CBiModel, noise, formaldehyde, TVOC, relative humidity in air, light, temperature and CO obtained2The respective impact index of the environmental parameter.
In some embodiments, the system 100 obtains the influence weight coefficient for each parameter according to the influence weight coefficient model for each parameter. The model is that the model is as follows,
Figure BDA0002214423990000101
wherein the weight coefficient KPAnd N represents the quantity value of the measured parameter, wherein the ratio of the efficiency factor corresponding to any one of the monitored parameters P to the sum of the efficiency factors of all the monitored parameters is shown.
After obtaining the weighting coefficients of the respective parameters, their respective weighting indices IEI-SE can be obtained accordinglyPAs in formula (3):
IEI-SEP=HP×KP (3)
wherein HPIndicating the corresponding impact index of the parameter P. Weighted index IEI-SE according to each parameter in environment informationPThe system 100 obtains the comprehensive learning efficiency environmental index IEI-SE of the current environment by using a learning environment quality evaluation model as shown in the following formula (4),
Figure BDA0002214423990000102
the corresponding learning efficiency level is then determined according to table 1 above.
The learning efficiency environmental index IEI-SE calculated by the above model and the corresponding quality grade of the suitable learning environment in table 1 are output by the system 100 to the display device 106 in real time to characterize whether the monitoring environment is suitable for learning within the full monitoring period.
According to the implementation mode of the application, the learning environment quality evaluation system represents whether the current environment is suitable for learning in real time on the basis of the monitored environment information through the online monitoring equipment, so that the simple identifiability of the learning environment quality is realized, and an effective technical support is provided for students to improve the learning efficiency environment.
