Description
Technical field
The present invention relates to smoking set the field of test technology, the pumping of cigarette smoking set in particular to a kind of low temperature does not burn
Inhale process detection method.
Background technique
Since the low temperature cigarette that do not burn is significantly less than traditional cigarette to the harm of human body, meet the World Health Organization and various countries
Associated mechanisms are about subtracting advocating for burnt drop evil, therefore the do not burn application of cigarette of low temperature gradually increases.It does not burn cigarette in low temperature
Smoking set be designed, manufacture during, in order to be accurately controlled aspiration procedure, smoking set must have suction detection function,
Suction detection becomes the more crucial technology of smoking set.
Suction detection is built upon on the basis of the control system of smoking set.It is in cigarette in existing suction detection process
Have and increase air pressure detection sensor in control system, and the air pressure detection sensor is arranged in suction air flue, passes through detection
Suction air flue in air pressure change come analyze and determine out aspiration procedure (including suction start, aspirate in, suction complete and aspirate
Mouth number calculating etc.).
But since existing smoking set is small in size, increased air pressure detection sensor be also required to volume it is small and detect
Precision is high, and this kind of air pressure detection sensor is expensive, and the hardware cost that suction detection method is realized is high, can be only applied to height
In shelves product, it not can be carried out universal.
In addition, the air pressure change aspirated in air flue all may during air pressure change is judged in through air flue
It is identified as aspiration procedure.However during routine use, the motion state of smoking set is changed, collides, falls, is moved suddenly
Make etc. to also result in the change of air pressure in suction air flue thus is considered aspiration procedure.False Rate is higher in entire deterministic process,
Precision is poor.
Drawbacks described above is worth solving.
Summary of the invention
In order to overcome the shortcomings of that existing technology, the present invention provide a kind of aspiration procedure detection method of smoking set.
Technical solution of the present invention is as described below:
A kind of aspiration procedure detection method of smoking set, in the heating system of smoking set, IC internal control unit passes through output power

Specific embodiment
With reference to the accompanying drawing and the present invention is further described in embodiment:
As shown in Figure 1, a kind of aspiration procedure detection method of smoking set, in existing smoking set heating system, including control inside IC
Unit and system control unit processed.
Wherein IC internal control unit by output power module drive heat generating device to heating do not burn cigarette into
Row heating.Specifically, carrying out goal-setting in IC internal control unit, and output power is controlled by PID computing module
Module, output power module carry out the driving device in drive system control unit, and then to heat generating device (fever tablet, hair
Heated filament etc.) it is heated.During heating, the temperature of temperature detecting module real-time detection heat generating device, and feed back to PID and count
It calculates in module and carries out adjustment.
The suction of smoking set can also take away a large amount of flue gas, Jin Erhui in addition to will lead to the air pressure change in suction air flue
Leading to the temperature of heating device reduces；Smoking set system is transported to heating device in order to maintain the temperature in heating device, by increase
Power；Since system output power increase also just has load current increases and cell voltage drops etc..Therefore smoking set is being taken out
Inhale the variation, load current variation and electricity of the temperature change, smoking set system output power that are will lead in heating device in the process
Cell voltage variation etc..
And the present invention is counted by the output energy to output power module, to determine the suction of smoking set
Journey, it is more accurate compared to the variation of temperature change, load current to heating device and the delta data of cell voltage,
It is not easily susceptible to ambient enviroment and the influence of its own, does not also need to increase any hardware resource.It is specific:
(1) it is influenced due to the temperature change of heating device by smoking set system temperature persistance, the good smoking set of temperature persistance adds
Hot device temperature variation is small；And aspiration procedure dynamics is light and grows, therefore temperature change is unobvious.Above-mentioned two o'clock causes only to detect
The temperature change of heating device is difficult to judge aspiration procedure.
(2) variation of cell voltage and battery capacity size, the new and old situation of battery have compared with Important Relations, and bring influences very
It extremely can be more than suction bring variation, therefore only judge aspiration procedure by the variation of cell voltage, judge that reliability is low.
(3) detection of the variation of load current needs to increase the ADC resources such as additional load current sample circuit, MCU, into
And increases the hardware cost entirely detected and hardware volume, corresponding overall cost and also will increase.
The present invention does careful refined analysis to the control process of smoking set and every pilot process parameter, is included in various rings
Data monitoring and the analysis of overall process are aspirated under border, various puffing regimens and Smoking regime, having found can be most quasi- in aspiration procedure
The element really analyzed and determined, and then carry out the specific deterministic process of aspiration procedure.
As shown in Figure 2 and Figure 3, establish respectively power FIFO array and output energy FIFO array, by statistical method into
The data statistics of row output energy.
To the output power of output power module, in first time period, (specific time span will be according to specific smoking set
Heating device and functional requirement adjust) in carry out continuing statistics, and the power FIFO is saved in the form of first in first out
In array (the power FIFO array in such as Fig. 2).
Power data in the length of every second time period in the statistics power FIFO array, then the data of statistics are asked
With/average, and then the output energy of output power module in length this period is obtained, and with the shape of first in first out
Formula is saved in the output energy FIFO array (the output energy FIFO array in such as Fig. 3).

3, using newly into it is old go out by the way of, the output power FIFO array data of output power module that statistics is obtained moves
It is one dynamic, and current performance number is saved in FIFO array；
4, the second timer adds 2；
5, judge that the second timer whether to the time, empties the second timer, the second timer if the second timer time if
It has not timed out, then gos to step 9；
6, output power FIFO array is summed/is averaged, obtain new output energy FIFO array,
7, using newly into it is old go out by the way of, will mobile one of output energy FIFO array data, and new energy value is saved in defeated
Out in energy FIFO array；
8, suction detection is carried out to smoking set；
9, it exits.
During output power module carries out power output, the judgment method of each aspiration procedure are as follows:
(1) in the case where not aspirating after the completion of preheating, the energy of output is used only for the heat that supplement nature distributes, this portion
It is smaller for dividing energy value, and relatively more steady, and fluctuation is little；
(2) it after suction starts, since a large amount of high-temperature flue gas is taken away in suction, is supplemented in and carrys out the lower air of temperature, this is resulted in
Temperature in heating device is lower rapidly, and system supplements the energy of consumption with regard to increasing output power at once for equilibrium temperature,
Therefore output energy persistently becomes larger as the mark of " suction starts "；
(3) with " suction starts " process on the contrary, output energy persistently becomes smaller as the mark of " suction terminates "；
(4) " suction starts " between " suction terminates " be " in suction "；
(5) the state number that " in the suction " of the cigarette that do not burn is heated by calculating, records its puff count.
