The earliest sampling period.
When obtained in S10 be a sampling period air inlet air quality parameters Qitm and air outlet wind speed Ntm, then,
Destination sample period i.e. sampling period thus；When obtained in S10 be multiple sampling periods continuous in time air inlet air
Mass parameter Qitm and air outlet wind speed Ntm, then, destination sample period are to sample earliest one in multiple sampling periods to adopt
The sample period.For example, it is assumed that be followed successively by continuous multiple sampling periods in S10 the first sampling period T1, the second sampling period T2,
Third sampling period T3.Wherein earliest sampling period T1 is the destination sample period.Destination sample collection dust quantity is for characterizing mesh
Before the mark sampling period starts, the collection dust quantity of filter screen born, i.e. destination sample period start time or initial time are missed
At the time of in poor range, filter screen bears collection dust quantity.Since processor is for the filter screen remaining life calculated every time, have
There are storage or writing function, therefore, the historical record that object set dust quantity Wg can be recorded by processor obtains.Certainly, target
Collection dust quantity Wg can also be obtained by other means.
It should be noted that target collection period can be any one sampling period in use.When filter screen for the first time
In use, first sampling period that target collection period as uses for the first time, then destination sample collection dust quantity is filter screen
It can bear always to collect dust quantity, can be obtained by factory parameter.
Processor can be calculated based on the accumulative collection dust quantity and object set dust quantity Wg that get according to preset algorithm
The remaining life of filter screen.The remaining life of filter screen can bear dust scale sign by residue, can also pass through residue
