[specific embodiment]
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Whole description.
Embodiment: please referring to attached drawing 1 to attached drawing 7, and the present embodiment is a kind of water-free detection method of cup, and detection program is pressed
According to being carried out shown in attached drawing 4, comprising the following steps:
The temperature for the fever tablet 11 for being set to 1 bottom of cup is acquired and recorded every the set time, is located at close to the cup 1
Temperature at the low water level 12 of bottom and the temperature at the high water level 13 above the low water level 12 are cached, described
Set time is 0.5 second, then by temperature current at the fever tablet 11 and the high water level 13, the low water level 12 and in advance
If temperature value one compare, the preset temperature value one is 99 DEG C, judges the fever tablet 11 and the high water level 13, described
Whether the current temperature in any one place is higher than preset temperature value one at low water level 12；If it is judged that be it is yes, then export
Anhydrous result stops anhydrous detection to the display screen 14 being located on the cup 1, and the display screen 14 is located at the cup 1
Side wall, see attached drawing 1.The temperature at one at the fever tablet 11 and the high water level 13, the low water level 12 is higher than
At 99 DEG C, illustrates that anhydrous in cup or water is evaporated, cause temperature excessively high, thus can be by judging the fever tablet 11 and institute
State high water level 13, at the low water level 12 in any one place temperature whether be higher than 99 DEG C may determine that in cup have it is anhydrous.
When detecting anhydrous, the Heat preservation of cup can be stopped, avoiding bottom of cups caused by continuing Heat preservation due to high temperature
It burns out, while also avoiding the complete also unnecessary electric energy loss caused by continuing to keep the temperature of the water evaporation in cup.
If it is determined that the temperature that any one place at the fever tablet 11 and the high water level 13, the low water level 12 is current
Degree is not higher than preset temperature value one, then subtracts temperature current at the low water level 12 using the current temperature of the fever tablet 11
Degree obtains the first temperature difference and compared with setting difference one, judges whether first temperature difference is lower than the setting difference one；
If it is determined that first temperature difference is not less than the setting difference one, the setting difference one is 15 DEG C, then by the fever
Continuously the temperature of the Fixed Time Interval three is divided according to sequencing when piece 11 heats and acquires the fever tablet 11 heating
It is not set as the first, second, third temperature, using the second temperature and the first temperature computation slope value one, utilizes described the
Three temperature and second temperature calculate slope value two, by the slope value one and the slope value two compared with default slope value one,
The default slope value one is 60；Judge whether the slope value one and the slope value two are greater than default slope value one；If
Judging result be it is yes, then export deposit-free and anhydrous result be to the display screen 14, and stop anhydrous detection；If it is determined that knot
Fruit be it is no, then output has sediment and has water to the display screen 14, and stops anhydrous detection.When dropping in cup 1 under water
When at low water level 12, the temperature of the water surface can be higher than the temperature of 1 bottom of cup, by comparing bottom of cups fever tablet 11 and low water level
Whether the difference of the temperature at 12 meets difference to judge whether there is water in cup 1.Cup is judged using the heating slope of fever tablet
Whether sub- bottom has sediment, is according to when bottom of cups has deposit-free, the heating slope of fever tablet is different；Work as cup
When sediment is arranged at bottom, the temperature of fever tablet is slow because the obstruction of sediment rises, therefore slope is smaller；When cup bottom
When portion's deposit-free, the temperature of fever tablet is because the ratio that the obstruction of not no sediment rises is very fast, therefore slope is bigger；So right
Fever tablet, which carries out heating slope detection, can judge that bottom of cups has deposit-free according to slope value.Deposit-free has been carried out to sentence
It is disconnected be in order to prevent cup because leading to the precipitating of appearance for when brewing the food such as soymilk, coffee, tealeaves, oat, continuing heat preservation
It is burnt and there is when sediment heat transfer cause to be mistaken for anhydrous phenomenon slowly.When detecting anhydrous, the heat preservation of cup can be stopped
Heating avoids bottom of cups caused by continuing Heat preservation from burning out because of high temperature, while it is complete to also avoid the water evaporation in cup
The also unnecessary electric energy loss caused by continuing to keep the temperature.
If it is determined that first temperature difference is lower than the setting difference one, then the temperature for utilizing the fever tablet 11 current
Each at least two temperature computations temperature difference before and after current temperature with the fever tablet 11；
It is obtained using the previous temperature that the current temperature of the fever tablet 11 subtracts the current temperature of the fever tablet 11
Second temperature is poor；The current temperature of the fever tablet 11 is subtracted using the previous temperature of the current temperature of the fever tablet 11
The first two temperature obtains third temperature difference；The fever tablet is subtracted using the latter temperature of the current temperature of the fever tablet 11
11 current temperature obtain the 4th temperature difference；The fever is subtracted using rear two temperature of the current temperature of the fever tablet 11
The current latter temperature of piece 11 obtains the 5th temperature difference；
Utilize each at least two temperature before and after the current temperature of the current temperature of the fever tablet 11 and the fever tablet 11
It is fitted temperature curve, it is described to set then by the second temperature difference and third temperature absolute value of the difference compared with setting difference two
Determining difference two is 5 DEG C, and by the 4th temperature difference and the 5th temperature absolute value of the difference compared with setting difference three, the setting is poor
Value three is 1.5 DEG C, by the fitting temperature curve compared with preset two temperature curves, judges the second temperature difference and the
Whether three temperature absolute value of the difference are greater than whether setting difference two, the 4th temperature difference and the 5th temperature absolute value of the difference are less than
Whether setting difference three, the fitting temperature curve approach any one temperature song in preset two temperature curves
Line；Preset two temperature curves are respectively the cup 1 be added when empty cup cup body temperature is 35 DEG C 50 DEG C water and
The temperature variation curve for the fever tablet 11 that the water of 20 DEG C of addition measures, is shown in attached drawing 5；
If it is determined that the second temperature difference and third temperature absolute value of the difference are greater than setting difference two, the 4th temperature
Difference and the 5th temperature absolute value of the difference are less than setting difference three, the fitting temperature curve approaches preset two articles of temperature songs
A temperature curve in line, then output has water result to the display screen 14, and stops anhydrous detection；Consider water in cup
State can generally allow the temperature of cup if to cup heating, not pouring the variation that the hot water in cup has temperature into
It increases, then the temperature of the water in cup is gradually reduced, by calculating the current temperature of fever tablet and fever tablet Current Temperatures
The difference of at least each two temperature in front and back, is to heat up according to the size of difference and the positive and negative water that can tentatively judge in cup
Or the amplitude of cooling and heating or cooling, if, without water, the temperature in cup is basically unchanged, temperature in cup
Difference also can very little.Then by least each two temperature fohs in front and back of the current temperature of fever tablet and fever tablet Current Temperatures at
It is bent to determine that the temperature curve being fitted to levels off to preset temperature for temperature curve, then compared with the temperature curve set
Heating curve or temperature lowering curve in line, or not forming curves, and then judge whether there is water in cup.
If it is determined that the second temperature difference and third temperature absolute value of the difference are no more than setting difference two or the described 4th
Temperature difference and the 5th temperature absolute value of the difference do not approach described preset not less than setting difference three or the fitting temperature curve
Any one temperature curve in two temperature curves, then adopted by the 3-axis acceleration sensor 15 being located on the cup 1
Collect the current inclination information of the cup 1, the cup 1 current inclination information 3-axis acceleration sensor 15
Current Z axis coordinate value indicates that the current inclination information of the cup 1 is pre- when the cup 1 is just typically located on desk
If inclination information three；When 1 side of cup is poured on desk, the current inclination information of the cup 1 is inclined to be preset
Slope information one；When the rim of a cup of the cup 1 is toppled over downwards, the current inclination information of the cup 1 is preset gradient
Information four；Compare the current inclination information of the cup 1 and preset inclination information one, judges that the cup 1 is current
Whether inclination information is greater than the preset inclination information one, and the preset inclination information one is three axis acceleration
The Z axis coordinate value for spending sensor 15 is equal to zero；If it is judged that be it is yes, then export anhydrous result to the display screen 14, and
Stop anhydrous detection.The preset inclination information three is the Z axis coordinate value of the 3-axis acceleration sensor 15 equal to negative
250, the preset inclination information four is that the Z axis coordinate value of the 3-axis acceleration sensor 15 is greater than zero, is led to here
The meaning of the coordinate value expression of the Z axis of the 3-axis acceleration sensor pre-set is crossed to be judged, when cup is normally put
When on desk, the coordinate value of Z axis is negative 250, and when cup side is poured on desk, the coordinate value of Z axis is zero, works as cup
Rim of a cup downward when, the coordinate value of Z axis is greater than zero.When the current inclination information, that is, Z axis coordinate value of the cup 1 is greater than
When 0, cup is in rim of a cup state directed downwardly, can topple over away if having water in cup, thus may determine that anhydrous in cup.When
When detecting anhydrous, the Heat preservation of cup can be stopped, bottom of cups caused by continuing Heat preservation is avoided to burn because of high temperature
It is bad, while also avoiding the complete also unnecessary electric energy loss caused by continuing to keep the temperature of the water evaporation in cup.
If it is determined that the current inclination information of the cup 1 is not more than the preset inclination information one, then acquire
The current status information of current temperature, the display screen 14 at the low water level 12, it is current at the low water level 12
The temperature inclination information and preset inclination information two current with preset temperature value two, the cup 1, it is described preset
Temperature value two is 40 DEG C, and the preset inclination information two is that the Z axis coordinate value of the 3-axis acceleration sensor 15 is negative
One eight zero, it is current to judge whether temperature current at the low water level 12 is less than the preset temperature value two, the cup 1
Whether whether inclination information is less than the preset inclination information two, the display screen 14 current in bright state；Such as
Fruit judges that temperature current at the low water level 12 is less than the current gradient letter of the preset temperature value two, the cup 1
Breath is less than the preset inclination information two, the display screen 14 is in bright state, then is added the fever tablet 11
Heat heating or Temperature fall slope detection, cup, which is in, at this time just puts or has certain gradient, but the direction of cup and water
Less than 45 °, water will not pour the angle of plane, cup be placed on desk or it is hand held can be carried out heating heating
Slope detection calculates the slope value three of temperature change during heat temperature raising or Temperature fall of fever tablet 11, judges institute
Slope value three is stated whether in preset slope range, slope<0 or slope>40, have when the preset slope range is anhydrous
Slope > 40 when water；If it is judged that be it is yes, then export anhydrous result to the display screen 14, and stop anhydrous detection；If
Judging result be it is no, then exporting judging result is to have water to the display screen 14, and stops anhydrous detection.
The preset temperature value judges the temperature at the low water level second is that determine that a human body can endure the temperature of scald
Whether degree is lower than preset temperature value second is that making a decision for operation in next step i.e. heating heating detection, in order to avoid because can in cup
Can have water heat detection when water overflow or pour out the scald that may cause, first judge herein fever tablet temperature whether
Higher than the temperature that human body can endure scald, because the temperature difference of the water in the temperature and cup of fever tablet is little.Only cup
For interior water when being lower than 40 DEG C, it is oblique that cup can just will do it heating heating in the state of picking up or having certain tilt angle
Rate detection.Certainly, when the water in cup is lower than 40 DEG C, cup, which is just being placed on desk, can also carry out heating heating slope detection.
When there is water in cup, heating detection is carried out, the temperature of fever tablet can quickly pass to the water in cup, in the temperature of fever tablet
What is risen is slow, and corresponding slope is also just smaller；And Temperature fall detection is carried out, due to the heat and air of the water in cup
Rate of heat exchange is slow, and the temperature of fever tablet declines also just slow, and corresponding slope is also just smaller.When nothing in cup
When water, heating detection is carried out, the ratio that the temperature of fever tablet rises is very fast, and corresponding slope is also just bigger；Cooling detection is carried out,
The temperature of fever tablet is higher than the temperature of air, and the heat of fever tablet passes to rapidly air, the comparison of the temperature decline of fever tablet
Fastly, corresponding temperature drop is also just bigger.It therefore can be by comparing fever tablet in heating heating or Temperature fall slope detection
Whether the slope variation range of temperature within the scope of preset temperature slope judges whether to have water in cup, sees attached drawing 6 and attached
Fig. 7, when there is water in cup, the curve of heat temperature raising or Temperature fall is different, can be calculated according to temperature change tiltedly
Whether rate value in preset slope range judges that whether there is water or not in cup；Similarly, when anhydrous in cup, heat temperature raising or
The curve of person's Temperature fall is also different, can be calculated according to temperature change slope value whether in preset slope range come
Judge that whether there is water or not in cup.
If current temperature is not less than the preset temperature value two or the cup 1 current at the low water level 12
Inclination information is not currently in bright state not less than the preset inclination information two or the display screen, then judges institute
State whether the current inclination information of cup 1 is equal to whether preset inclination information three, the display screen 14 are current is in bright
State, the preset inclination information three is that the Z axis coordinate value of the 3-axis acceleration sensor 15 is negative 250；Such as
It is bright that fruit judges that the current inclination information of the cup 1 is not at not equal to preset inclination information three or the display screen 14
State, then directly terminate anhydrous detection；It can make the water in cup when temperature is relatively high, if the gradient of cup is bigger
It overflows or pours and iron user, therefore when condition is not complyed with without anhydrous judgement；
If it is determined that the current inclination information of the cup 1 is equal to preset inclination information three, the display screen 14
It is currently at bright state, then the fever tablet 11 is subjected to heat temperature raising or Temperature fall slope detection, calculates the fever
Whether the slope value four of temperature change during heat temperature raising or Temperature fall of piece 11 judges the slope value four described pre-
If slope range in, slope<0 or slope>40 when the preset slope range is anhydrous, slope>40 when having water；If sentenced
Disconnected result be it is yes, then export anhydrous result to the display screen 14, and stop anhydrous detection；If it is judged that be it is no, then it is defeated
Judging result is to have water to the display screen 14, and stop anhydrous detection out.When the temperature of the water in cup is greater than or equal to 40
DEG C when, in order to avoid scald cup need to be placed on desk or other objects just put standing three seconds after, cup is just putting i.e. institute
When the coordinate value for stating 3-axis acceleration sensor Z axis is -250, heating heating or Temperature fall slope detection can be just carried out.
Then by comparing the slope value of fever tablet temperature in heating heating or Temperature fall slope detection whether in preset temperature
Judge whether there is water in cup in slope range, sees attached drawing 6 and attached drawing 7, when there is water in cup, heat temperature raising or nature
The curve of cooling is different, can calculate whether slope value in preset slope range judges cup according to temperature change
It is interior that whether there is water or not；Similarly, when anhydrous in cup, the curve of heat temperature raising or Temperature fall is also different, can be according to temperature
Degree variation calculates whether slope value in preset slope range judges that whether there is water or not in cup.
The method of anhydrous detection of the invention, according to cup in different states existing different information, phase is provided
The method of corresponding detection cup state.Such as detect the temperature of cup different location；Judge the temperature of the current different location of cup
It is compared with the temperature of each position of cup when anhydrous and judges whether there is water in cup；Or the cup fever tablet that will be obtained
Temperature data be fitted to temperature curve, according to temperature change (difference and change curve) of the water in cup judge in cup whether
There is water, a kind of situation is that curve of the water in temperature-rise period in cup levels off to 50 DEG C of water when being added to 35 DEG C of empty cup cup bodies
Curve, another situation is that curve of the water in cup in temperature-fall period levels off to 25 DEG C of water and is added to 35 DEG C of empty cup cups
Curve when body.Empty 35 DEG C of cup cup body temperature, 50 DEG C of water are added, since the temperature of the water of addition is high compared with the temperature of cup body, fever
The temperature that piece detects first should be increased quickly, be uniformly dispersed then as heat, and temperature rising no longer rises to a certain extent,
Curve becomes gentle；And the water of 25 DEG C of addition, since cup body temperature is high compared with the temperature of the water of addition, the temperature that fever tablet detects
Should first fast cooling, then temperature drops to no longer declines to a certain degree, and temperature curve becomes flat；When the temperature of cup fever tablet
Spend the temperature curve that is fitted to level off to one in this two temperature curves when, it can be determined that there is water.
When there is water in cup, heating detection is carried out, the temperature of fever tablet can quickly pass to the water in cup, in temperature
What is risen is slow, and corresponding slope is also just smaller；And cooling detection is carried out, since the heat and air heat of the water in cup are handed over
Throw-over degree is slow, and the temperature of fever tablet declines also just slow, and corresponding slope is also just smaller.When anhydrous in cup
When, heating detection is carried out, the ratio that the temperature of fever tablet rises is very fast, and corresponding slope is also just bigger；Cooling detection is carried out, is sent out
The temperature of backing is higher than the temperature of air, and the heat of fever tablet passes to rapidly air, and the ratio of the temperature decline of fever tablet is very fast,
Corresponding temperature drop is also just bigger.Heat temperature raising slope detection or Temperature fall detection are carried out, is risen according to heating sheet in heating
Whether slope value within the scope of preset temperature slope determines whether water in the slope detection process of mild Temperature fall；From this
The characteristic of a little temperature changes may determine that whether there is water or not in cup.When detecting anhydrous, the heat preservation that can stop cup adding
Heat avoids bottom of cups caused by continuing Heat preservation from burning out because of high temperature, while it is complete also to also avoid the water evaporation in cup
The unnecessary electric energy loss caused by continuing to keep the temperature.It is convenient and practical.
