Sequence, including according to involved function by it is basic simultaneously in the way of or in the opposite order, carry out perform function, this should be of the invention
Embodiment person of ordinary skill in the field understood.
Fig. 1 is the flow chart of the replacing reminding method of the air conditioner filter screen of one embodiment of the invention.
As shown in figure 1, changing reminding method includes：
S101, obtain work information of the air-conditioning under each operating mode.
Specifically, for air-conditioning in the state of difference, it changes airspeed difference, and therefore, the operating mode of current air-conditioning is entered
Row inductive statistics, inductive statistics mainly include, air inlet endless form, air blower gear, changes in temperature pattern and air-out mode.Wherein,
Air inlet endless form includes interior circulation and outer circulation, and air blower gear is depending on different vehicles, for example, air blower gear can
To be 1-7 shelves, changes in temperature pattern includes refrigeration mode and heating pattern, air-out mode include blowing surface model, blow pin pattern, blow face and
Pin pattern, blow pin and defrosting mode and defrosting mode.Therefore, by permutation and combination, we can calculate work existing for air-conditioning
Condition quantity.For example, 2 kinds of air inlet endless form, 7 kinds of air blower gear, 2 kinds of changes in temperature pattern, 5 kinds of air-out mode, then the work of air-conditioning
Condition quantity is 2*7*2*5=140 kinds.And then pass through experiment of divulging information, it can be deduced that air blower under each operating mode changes airspeed
V1-V140, so as to which the airspeed that changes of air blower corresponding to different operating modes is stored into air-conditioner controller.
On vehicle after electricity, air-conditioner controller starts to judge the current working of air-conditioning, and gathers air-conditioning under current working
Work information, wherein, work information include air-conditioning under current working air blower change airspeed and current working it is lasting when
Between and surrounding air in the existing concentration of fine particle and the adsorption efficiency of anion generator.That is, airconditioning control
Device can judge air inlet endless form, air blower gear, changes in temperature pattern and air-out mode, so as to according to air inlet endless form, air blast
Gear, changes in temperature pattern and the air-out mode of machine determine the current working of air-conditioning.
And then the corresponding relation for changing airspeed of the operating mode that can be obtained from the experiment of storage of air-conditioner controller and air blower,
Airspeed V is changed according to the current working of air-conditioning acquisition air blowern.Also, air-conditioner controller obtains air-conditioning under current working
Duration Tn, in other words, air-conditioner controller carries out timing to working time of the air-conditioning under operating mode n, when operating mode changes
When, timing terminates, so as to obtain the duration of air-conditioning work under the operating mode.
In addition, air-conditioner controller can also gather the existing concentration P of fine particle in surrounding air by sensornWith it is negative
The adsorption efficiency η of ion generator.

PnRepresent under operating mode n, the concentration (for example, PM2.5) of the outer fine particle of the car that sensor detects, unit is ug/m3, TnTable
Show under operating mode n, the timing time by timer to the air-conditioning work time, unit is s, and η represents anion generator absorption
The efficiency of fine particle, such as 70% can be made.
S102, determine that air conditioner filter screen adsorbs the adsorbance of fine particle under each operating mode according to work information.
Specifically, by air-conditioning, air blower changes airspeed V under current workingn, current working duration Tn, environment
The existing concentration P of fine particle in airnMultiplying is carried out with the adsorption efficiency η of anion generator, is drawn under the operating mode
Air conditioner filter screen adsorbs the adsorbance of fine particle.
S103, the adsorbance for adsorbing fine particle under each operating mode according to air conditioner filter screen calculate the history suction of air conditioner filter screen
Attached total amount.
Specifically, when air-conditioning works under new operating mode, the airspeed that changes of air blower of the air-conditioning under new operating mode is obtained, and
The existing concentration of fine particle in surrounding air under new operating mode is detected, so as to calculate air-conditioning in new work by above-mentioned identical principle
The adsorbance of air conditioner filter screen under condition for fine particle.And then to air conditioner filter screen of the air-conditioning under different operating modes to fine grained
The adsorbance of thing is added up, and obtains the history absorption total amount Max of air conditioner filter screen.Wherein,
Wherein, in order to avoid the overabundance of data preserved in air-conditioner controller, only preserve in air-conditioner controller and obtained after adding up
The history absorption total amount Max of the air conditioner filter screen arrived, and median can all be replaced by follow-up data.
S104, when history absorption total amount reaches predetermined threshold value, the prompt message of air conditioner filter screen is changed in generation.
Specifically, when the history absorption total amount Max of air conditioner filter screen reaches default adsorbance threshold value, air-conditioner controller generation
Prompt user to change the prompt message of air conditioner filter screen, and vehicle mounted multimedia is sent to according to prompt message generation message data and set
It is standby, for example, display screen, is that user is prompted by vehicle-mounted multimedia equipment.Wherein, prompt message includes but is not limited to word and carried
Awake, sound prompting and indicator lamp prompting etc..
It should be appreciated that air conditioner filter screen can be PM2.5 filter screens in the present embodiment, fine particle is PM2.5 particulate matters.
Certainly, air conditioner filter screen can also be common air filter screen, and the fine particle of detection can also be others, for example, dust,
PM10, pollen etc..
In one embodiment of the invention, after the prompt message that air conditioner filter screen is changed in generation, by air conditioner filter screen
History absorption total amount is reset, so that in air-conditioning work room, fine grained is adsorbed to the air conditioner filter screen newly installed according to the operating mode of air-conditioning
The adsorbance of thing re-starts statistics.
The replacing reminding method of the embodiment of the present invention, by being determined to the operating mode of air-conditioning, using air-conditioning in different works
The existing concentration and anion that change fine particle in airspeed, the surrounding air outside car of duration, air blower under condition
The adsorption efficiency of generator determine air-conditioning under different operating modes air conditioner filter screen absorption fine particle adsorbance, and then pass through by
The adsorbance of air conditioner filter screen absorption fine particle under different operating modes is added up, when cumulative history absorption total amount reaches early warning
Alarmed during value, remind user to change air conditioner filter screen, on the one hand may remind the user that and change filter screen in time, avoid health
It is compromised, on the other hand improves the accuracy of testing result, reduces the cost that user frequently changes filter screen.
