After the resistance value of the critesistor detected when resistance deviation value is to boiling point is modified, obtain revising resistance, foundation
Revise resistance and determine the temperature value of described boiling point.
For the temperature sensing device being conventionally used to collecting temperature, its generally by temperature sensor with
Single-chip microcomputer detection voltage and then judgement Current Temperatures after divider resistance series connection dividing potential drop.But, temperature sensor itself may
There is error, and under condition of different temperatures, error amount is different.Such as, if using R25=100K ± 2%
Sensor, its temperature is the highest, deviation is the biggest, and this sensor itself has overgauge and minus deviation, this deviation with
Machine, it is impossible to correct so that the height above sea level error drawn of retrodicting is bigger.
To this, the data sampled, by arranging a temperature reference point, are calibrated by the present invention, eliminate and pass
The error of sensor own, reaches the purpose of sampling with high precision temperature.
Concrete, forward Fig. 2 a and Fig. 2 b to, wherein Fig. 2 a shows an embodiment of temperature sampling circuit
Circuit diagram, and Fig. 2 b shows the circuit diagram of an embodiment of temperature jump signal generating circuit.
This temperature sampling circuit 200 mainly includes fixed resistance 201 and the temperature-sensitive being series between power supply and ground connection

Temperature jump signal generating circuit 204 shown in Fig. 2 b mainly includes that be series between power supply and ground connection consolidates
Determine resistance 205 and high accuracy Kick type temperature switch 206.This high accuracy Kick type temperature switch 206 further with
One electric capacity 207 is in parallel.(such as, this temperature jump signal generating circuit 204 can reach preset temperature value in water temperature
This preset temperature value preferably between 80 to 90 DEG C, more preferably 85 DEG C) time occur high accuracy Kick type temperature open
Close 206 disconnections.So, single-chip microcomputer will receive cut-off signal, now carries out temperature sampling and temperature curve school
Accurate.
Based on said structure, the food cooking machine plateau self-adapting method of the present invention can be entered before step 101
One step includes the step that temperature curve is calibrated, and specifically includes:
First, the thermistor voltage (AD under single-chip microcomputer detection preset temperature value (85 DEG C as escribed above)
Magnitude of voltage VAD)；Then, the current resistance of this critesistor, such as basis are calculated according to this thermistor voltage
VAD=VCC*R1/ (R1+R), R1 are the resistance (i.e. divider resistance resistance) of fixed resistance 201, VCC
For fixed value (chip power supply voltage, generally 5V), V is the magnitude of voltage sampled, then can calculate and work as
Resistance R of front critesistor；Finally, by the resistance table of this current resistance and this critesistor and preset temperature
The reference resistance (the reference resistance being in this example at 85 DEG C) of value correspondence compares, to determine and record this
The deviation value of critesistor, can show that this critesistor is positively biased or negative bias and deviation value T thereof；By this deviation value T
Record.Owing to the change in resistance between 85 DEG C to 100 DEG C is less, the deviation value that can be similar to critesistor is fixed.
When follow-up calibration, after heating the water to boiling, anti-flow electrode detects signal, and single-chip microcomputer is sampled
Current voltage value VAD, and then calculate current critesistor resistance R；If T is positively biased, calculates and revise resistance R '=
R* (1-T), if T is negative bias, calculates R '=R* (1+T)；Correction resistance R that will calculate ' at this temperature-sensitive electricity
The resistance table of resistance is inquired about, then can draw and corresponding revise resistance R ' temperature spot, this temperature spot is currently practical
Temperature spot, this temperature spot can be set to the boiling point of current altitude by such single-chip microcomputer.Draw according to this boiling point and work as front ring
The height above sea level in border.Additionally, based on said temperature sample circuit 200, steps discussed above 101 can enter one
Step expands into: when the water in this food cooking machine is heated to boiling point, this thermistor voltage of sampling；According to this
Thermistor voltage calculates the current resistance of this critesistor；Eliminate this deviation value from this current resistance, work as to obtain
Front correction resistance；The temperature value during boiling point of this food cooking machine is obtained according to this correction resistance.
Steps discussed above 103 can further spread out for: height above sea level determined by Jiang and memorizer are deposited
The height above sea level of storage compares；If both are different, then with determined by height above sea level update this memorizer internal memory
The height above sea level of storage.Additionally, this step 103 can also include: this food cooking machine stores according in this memorizer
Height above sea level call corresponding processing routine.Such as, this processing routine can include corresponding to less than or equal to sea
Pull out first for the processing routine of 2000 meters and corresponding to the second processing routine more than height above sea level 2000 meters, or at this
Reason program can also segment the more processing program corresponding to more height above sea level sections further.
To sum up, the present invention, by being accurately detected boiling temperature, can learn current altitude.Food cooking
In the course of the work, single-chip microcomputer, by calling different pulping program under Different Altitude, can reach in Different Altitude machine
Under, by abundant infusion, make the purpose of harmful substance abundant decomposes volatilization in bean milk.
The flow process of the refinement further of food cooking machine plateau self-adapting method is shown turning now to Fig. 3, Fig. 3
Figure.As it can be seen, the method 300 includes:
First, single-chip microcomputer first reads altitude parameters 301 in EEPROM after the power-up；After entered function 302,
Different pulping program 303-304 is called according to altitude parameters.In pulping process, after water seethes with excitement, monolithic
The temperature of machine record boiling water, according to the temperature of boiling water, can calculate current height above sea level 305.If current sea
Degree of lifting and the altitude parameters inconsistent 306 read in EEPROM when powering on, then by height above sea level in EEPROM
Parameter updates, and deposits into current altitude parameters 307, and calls the pulping program 308 of current altitude；If working as
Front height above sea level is consistent with the altitude parameters read in EEPROM when powering on, then continue according to current system
Slurry program performs.In this embodiment, altitude parameters can have two kinds of representations: 1, arranges a marginal value,
Such as height above sea level 2000 meters, the height above sea level more than 2000 meters calls a kind of pulping program, less than or equal to 2000
The height above sea level of rice calls another kind of pulping program；It is interval that 2, height above sea level is set, such as height above sea level 0-1000 rice, adjusts
With pulping program 1, height above sea level 1000-2000 rice, call pulping program 2, by that analogy.This plateau is adaptive
The induction method 300 plateau self-adapting method 100 that compares adds the altitude parameters step updated in EEPROM,
More intelligent.Wherein correct step about temperature sensor deviation value identical with plateau self-adapting method 100, no
Repeat again.
Those skilled in the art can be obvious, the above-mentioned exemplary embodiment of the present invention can be carried out various amendment and
Modification is without departing from the spirit and scope of the present invention.Will in appended right accordingly, it is intended to make the present invention cover
Ask the modifications of the present invention in the range of book and equivalent arrangements thereof and modification.
