Start then central processing unit and starts the continuation countdown of timing trigger module；
Once respective level service life is less than the filter core service life reminder time, it indicates that module corresponds to filter core indicating area
Carry out the instruction of the filter core service life.
Using the above scheme, since the raw water in water bar generally passes through primary filter and secondary filter, apart from supercharging
Pump that nearest filter core service life is most short, with the sequentially connected filter core grade of booster pump according to service life length from low to high
It is ranked up, accomplishes the service life of the actual planning filter core of science；
The service life of respective level filter core is stored in filter core standard operating life data library, filter core remaining life is reminded
The remaining life reminder time corresponding to respective level filter core is stored in temporal database；Once being pressurized pump work, meter
When trigger module countdown is opened to filter core, and once reach the reminder time of corresponding filter core service life, indicating module corresponds to
Filter core indicating area carries out the instruction of the filter core service life, replaces water bar filter core in time convenient for user, and each grade is fallen
Timing and counting-down reminding interfere with each other work independent of one another；
Most depends on the water that is filtered of filter core itself to the service life of filter core, therefore different brackets filter core uses the longevity
Duration of the duration with reference to supercharging pump work is ordered, one makes the timing of the service life of filter core more accurate；Secondly as far as possible most
Bigization reasonably uses filter core.
Preferably, further including：
Water quality probe TDS：It is installed at booster pump and is used to detect at booster pump plasma concentration in water；Respective level defined in it
Filter core standard service life is TMark 1、TMark 2、TMark 3、TMark 4、……TMark n, corresponding to all grade filter core standard service lifes it is equal from
A concentration of A of sonMark, the surveyed plasma concentrations of current water quality probe TDS are Ai；
Computing module：Built-in first discriminant function A (xi)=∣Ai-AMark∣, first compare parameter A (xMark), plasma concentration is to filter core
The interference coefficient η of service life；And computing module interval supercharging pump work expire Δ T and is circulated in water quality probe TDS for one and transfers
Current water quality plasma concentration Ai；
If A (xi) < A (xMark), respective level filter core standard service life is TMark 1、TMark 2、TMark 3、TMark 4、……TMark n；If A (xi) > A
(xMark), respective level filter core standard service life is TMark 1*η、TMark 2*η、TMark 3*η、TMark 4*η、……TMark n* η, and η <1, central processing
Device interval supercharging pump work expires Δ T and is circulated in the mark for transferring all grade filter cores in filter core standard operating life data library for one
Quasi- service life will be simultaneously directed in timing trigger module respective level channel according to corresponding grade.
Using the above scheme, the service life of filter core is in fact one and is determined by several factors, therefore unsuitable
The service life for being simply defined as which kind of filter core is how many, and largely, the service life of filter core will be according to filter medium cleaning
Degree；Water quality probe TDS by the water quality of filter core in real time to will be detected, if the water quality plasma concentration distance mark detected
Quasi- water quality plasma concentration gap is more than A (xMark), then it is T by respective level filter core standard service lifeMark 1*η、TMark 2*η、TMark 3*η、
TMark 4*η、……TMark n* η more reasonably adjusts the service life of filter core.
Preferably, the computing module is also built-in with the second discriminant function：Ai-AMark
If A (xi) > A (xMark), and Ai-AMark< 0, respective level filter core standard service life are TMark 1*γ、TMark 2*γ、TMark 3*γ、
TMark 4*γ、……TMark n* γ, and γ > 1；
If A (xi) > A (xMark), and Ai-AMark> 0, respective level filter core standard service life are TMark 1*η、TMark 2*η、TMark 3*η、TMark 4*
η、……TMark n* η, and η < 1.
Using the above scheme, if the water quality plasma concentration criterion distance water quality plasma concentration gap detected is more than A
(xMark), then it is T by respective level filter core standard service lifeMark 1*η、TMark 2*η、TMark 3*η、TMark 4*η、……TMark n* η, filter medium are clean
Cleanliness considers into the usage time of filter core；But A (xi) > A (xMark) there are A (xi)-AMark< 0 and A (xi)-AMark0 two kinds of situations of <,
Filter core is suitably replaced in advance if the water quality plasma concentration of water bar use environment is more than standard water quality plasma concentration；If water bar
The water quality plasma concentration of use environment is less than standard water quality plasma concentration and then suitably delays to replace filter core, realizes maximized
Use filter core.

The standard service life that all grade filter cores are transferred in filter core standard operating life data library is circulated in for one and will be according to right
Grade is answered to be directed in timing trigger module respective level channel.Fine tuning is made to the standard service life of respective level filter core,
To ensure that filter core plays its good filtration during using water bar.
It avoids user from being in space state to the usage time of water bar, further includes using in water bar filter element life monitoring system
Timing module is used to the water bar of water bar usage time in record user；When booster pump works for the first time, water bar uses timing mould
Block opens timing.What water bar was recorded using timing module is usage time of the user to water bar, and timing trigger module then records
Be the usage time of booster pump namely the usage time of filter core.
Due to the water bar that newly dispatches from the factory once starting, though later stage not actuated booster pump for some time, but the filtering of filter core
The sundries filtered before is stained in film, miscellaneous affair has certain pollution and corrosivity, prolonged pollution meeting pair to filter membrane
The service life of filter core has an impact, thus water bar using be provided in timing module water bar filter core service life cut down threshold value and
