wherein the weight coefficient KiAnd N represents the quantity value of the measured parameter, wherein the ratio of the efficiency factor corresponding to any one parameter i in the monitored parameters 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 IPEI may be obtained accordinglyiAs in formula (3):
IPEIi＝Hi×Ki (3)
wherein HiAnd (4) representing the influence index corresponding to the parameter i. According to weighted index IPEI of each parameter in environment informationiThe system 100 utilizes a working environment quality evaluation model, as shown in the following formula (4), to obtain a comprehensive working efficiency environment index IPEI of the current environment,
and then determining the corresponding working efficiency grade according to the table 1.
In some cases, H of one or more of the monitored environmental parametersiThe corresponding score number may be smaller than a predetermined fail threshold, for example, when the score is smaller than 60 minutes, it is determined that there is a fail item, which is obtained by calculating the environmental impact factor PF of each environmental index by equation (5)iAnd finding out the corresponding environmental influence factor according to the formula (6)Maximum value of (PF)maxMixing PFmaxThe corresponding environmental parameter is determined as the most adverse environmental impact factor in the room.
PFi＝(100-Hi)×Ki (5)
PFmax＝{PF1,PF2,…,PFi,…,PFN} (6)
The operating efficiency environmental index IPEI calculated from the above model, the corresponding suitable operating environment quality level in table 1, and the corresponding parameters of the worst possible environmental impact factors are output by the system 100 to the display device 106 in real time to characterize whether the monitored environment is suitable for operation during the full monitoring period.
