Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
The processing side of PPG signal in the electromagnetic heating system proposed according to embodiments of the present invention described with reference to the accompanying drawings
Method, computer readable storage medium, the processing unit of PPG signal and the electromagnetism with the processing unit in electromagnetic heating system
Heating system.
In an embodiment of the present invention, electromagnetic heating system can be the electricity such as electromagnetic oven, electromagnetic rice cooker, prevention electromagnetic pressure cooker
Magnetic heats product.
Fig. 1 is the main circuit diagram of electromagnetic heating system according to an embodiment of the invention.As shown in Figure 1, the electromagnetism adds
The main circuit of hot systems may include protective tube F1, rectifier bridge D1, filter inductance L1, filter capacitor C1, heating coil L2, resonance electricity
Hold C2, power switch tube IGBT, main control chip IC1, IGBT drive module U2 and other circuit module U3.
After electromagnetic heating system works on power, electric main after protective tube F1, by rectifier bridge D1 rectified with
The direct current of output ripple exports stable direct current after being then filtered by filter inductance L1 and filter capacitor C1
The resonant tank that electricity is extremely made of heating coil L2 and resonant capacitance C2.The port the PPG output control pulse of main control chip IC1 is extremely
IGBT drive module U2, converts IGBT driving signal for PPG signal to control the turn-on and turn-off of power switch tube IGBT,
And then realize computer heating control.
During heating, when using invariable power heating, main control chip IC1 is according to actual power P1 and target power P
Between difference adjust target PPG value, for example, increasing target PPG value as P1 < P;As P1 > P, reduce target PPG
Value.It is needed sometimes for control, target PPG value is often adjusted in the heating process of single half-wave.Conventional main control chip IC1
Generally 8 single-chip microcontrollers, register is 8, thus the count maximum of register (binary system: 1,111 1111), is for 255
Control precision and pulse width need, general objectives PPG value be greater than 8 (such as 11, maximum value 4095, binary system:
111 1,111 1111), when frequently adjustment target PPG value, it is easy to the carry of height interdigit occur or borrow.
Specifically, 11 targets can be met using two registers (high register and low register)
PPG value demand, when target PPG value is assigned to target PPG register, first assignment low-value, then assignment high-value, it is main simultaneously
The port the PPG output control pulse of chip IC 1 is controlled, and one secondary control pulse of every output, PPG counter add 1 automatically, work as PPG
The value of counter be equal to target PPG register value (high-value and low-value of i.e. current PPG value respectively with target PPG value
High-value and low-value are equal) when, stop output control signal.
Under normal circumstances, during being adjusted to target PPG value, if carry does not occur or borrows for target PPG value
Position, for example, target PPG value by 508 (binary system: 001 1,111 1100) be adjusted to 511 (binary system: 001 1,111 1111),
Main control chip IC1 will export normal control pulse according to target PPG value 511, as shown in Figure 2.
When carry occurs for target PPG value, for example, target PPG value by 511 (binary system: 001 1,111 1111, low-value
Be 1,111 1111, high-value 001) be adjusted to 515 (binary system: 010 0,000 0011, low-value is 0,000 0011, high-order
010) value is.Due to being first assignment low level, then an assignment high position in assignment procedure, and assignment needs the regular hour, so
During high-value updates (practical high-value does not update also), PPG counter and target PPG register carry out matching ratio
Compared with when the low-value of PPG counter is equal with the matching of the low-value of target PPG register, i.e. the value of PPG counter is equal to
259 (binary system: 001 0,000 0011), stop output control signal.The PPG value that will result in reality output in this way is much smaller than
Target PPG value, as shown in figure 3, PPG output waveform is caused to be distorted, PPG pulse width become smaller suddenly (in Fig. 3, T1 and T3
For normal width, T2 distortion width), IGBT conducting electric current becomes smaller suddenly, and resonance potential becomes smaller, and shows as the collector of IGBT
(pole C) voltage becomes smaller.
When target PPG value borrows, for example, target PPG value by 258 (binary system: 001 0,000 0010, low-value
Be 0,000 0010, high-value 001) be adjusted to 255 (binary system: 000 1,111 1111, low-value is 1,111 1111, high-order
000) value is.Likewise, PPG counter is posted with target PPG during high-value updates (practical high-value does not update also)
Storage carries out matching comparison, when the low-value of PPG counter is equal with the matching of the low-value of target PPG register, i.e. PPG meter
The value of number device is equal to 511 and (binary system: 001 1,111 1111), stops output control signal.It will result in reality output in this way
PPG value be much larger than target PPG value, as shown in figure 4, cause PPG output waveform distort, PPG pulse width become larger suddenly (in Fig. 4,
T1 and T3 is normal width, T2 distortion width), IGBT conducting electric current becomes larger suddenly, causes the C pole tension of IGBT excessively high, out
Existing electromagnetic noise, in some instances it may even be possible to burn IGBT.
In order to solve during electromagnetic heating system heats, because height interdigit occurs in target PPG value adjusted
It borrows or the problem of the PPG waveform of reality output is caused to be distorted for carry, the invention proposes in a kind of electromagnetic heating system
The processing method of PPG signal.
Fig. 5 is the flow chart of the processing method of PPG signal in electromagnetic heating system according to an embodiment of the present invention.Such as Fig. 5
Shown, the processing method of PPG signal can comprise the following steps that in the electromagnetic heating system of the embodiment of the present invention
S1 judges whether current goal PPG value needs to adjust during electromagnetic heating system heating.
It specifically, can be according to the difference between actual power P1 and target power P to determine whether needing to adjust target PPG
Value, for example, reducing target PPG value as P1 > P;As P1 < P, increase target PPG value.
S2 judges target PPG value adjusted with the presence or absence of carry/borrow if current goal PPG value needs to adjust
Position.
Wherein, when increasing target PPG value, target PPG value adjusted is likely to occur carry phenomenon;To mesh
When mark PPG value is reduced, in fact it could happen that the phenomenon that borrowing.
For example, current goal PPG value is 508 (binary systems: 001 1,111 1100), at this time if P1 < P, needs to increase
Big target PPG value, it is assumed that target PPG value increases by 4, then the target PPG value after increasing is 512 (binary systems: 010
00000000), occurs low-value at this time to high-value carry;Assuming that target PPG value increases by 2, then the target PPG value after increasing
(binary system: 001 1,111 1110), do not occur low-value at this time to high-value carry for 510.
Current target value be 258 (binary system: 001 0,000 0010), if P1 > P, needing to reduce target PPG value,
Assuming that target PPG value reduces 3, then the target PPG value after reducing (binary system: 000 1,111 1111), occurs at this time for 255
Low-value is borrowed to high-value;Assuming that target PPG value reduces 1, then the target PPG value after reducing is 257 (binary systems: 001
0000 0001), does not occur low-value at this time and borrows to high-value.
S3 will be stored with target PPG value adjusted if target PPG value adjusted does not have carry/borrow
First register is exported as destination register control PPG signal, and according to the value of the first register to the value of the second register
It is updated.
S4, if there are carries/borrow for target PPG value adjusted, using the second register as destination register control
PPG signal output processed.
According to one embodiment of present invention, it is updated, is wrapped according to value of the value of the first register to the second register
It includes: the value of the first register is subtracted into the first preset value to obtain the value of the second register.Wherein, the first preset value can be 1
It can be 0.1us~1us, the digit and mesh of the first register and the second register that any value in~20, i.e. PPG, which adjust width,
The digit for marking PPG value is identical.
Specifically, first judging whether target PPG value adjusted will appear carry when needing to adjust target PPG value
Or it borrows, then determine that destination register is the first register or the second register.If PPG value adjusted do not occur into
Position borrows, then using the first register as destination register, and target PPG value adjusted is assigned to the first register.
The value of the second register is updated simultaneously, i.e. target PPG value of every adjustment, updates the value of second register, make
The value in the second register is obtained always close to the value of the target PPG of last time adjustment, for example, the value of the first register is subtracted
Value of first preset value (such as 4) as the second register.
When needing to adjust target PPG value again, if PPG value adjusted carry occurs or borrows, second is posted
Storage is assigned to the second register as destination register, and by target PPG value adjusted.Since the value of the second register is
The target PPG value that the last time updates according to the value of the first register, and not adjusting, while the value is close to actually required mesh
Mark PPG value, it is possible to effectively prevent target PPG value to issue mutation, so that PPG waveform be effectively prevent to be distorted, cause to collect
Electrode voltage is too high or too low, and then leads to problems such as electromagnetic noise occur, IGBT is caused to damage.
Further, Fig. 6 is the processing method of PPG signal in electromagnetic heating system according to an embodiment of the invention
Flow chart, as shown in fig. 6, the processing method of PPG signal can comprise the following steps that in the electromagnetic heating system
The first register P2EA is arranged as destination register in S101.
S102, judge current goal register ± i whether occur into/borrow.If so, executing step S105;If not,
Execute step S103.
S103, P2EA=P2EA ± i adjusted, the first preset value of value P2EB=P2EA- (such as 4) of the second register.
S104, the first register P2EA are destination register.
S105, the second register P2EB are destination register.
S106, P2EA=P2EA ± i adjusted.
In addition, it is necessary to explanation, in other embodiments of the invention, when there is carry phenomenon, the second register
Value can also be the maximum value for not generating carry confirmed according to the value of the first register, for example, the first current register
Value be that 508 (binary system: 001 1,111 1100), the value of the first register adjusted is 515 (binary systems: 010
00000011), i.e., when target PPG value is adjusted to 515 by 508, then the value of the second register can for 511 (binary system:
0011111 1111)。
When occurring borrowing phenomenon, the value of the second register can also be not generating according to the confirmation of the value of the first register
The minimum value of carry, for example, the value of the first current register be 258 (binary system: 001 0,000 0010), adjusted the
The value of one register is 255 (binary systems: 000 1,111 1111), i.e., when target PPG value is adjusted to 255 by 258, then second
The value of register can be 256 (binary systems: 001 0,000 0000).It is prominent that the sending of target PPG value also can be effectively prevented as a result,
Become, so that PPG waveform be effectively prevent to be distorted, cause collector voltage too high or too low, so cause to occur electromagnetic noise,
The problems such as causing IGBT to damage.
In conclusion in electromagnetic heating system according to an embodiment of the present invention PPG signal processing method, in electromagnetic heating
During system heats, judges whether current goal PPG value needs to adjust, if current goal PPG value needs to adjust, sentence
Target PPG value adjusted of breaking is with the presence or absence of carry/borrow.If there is no carry/borrow in target PPG value adjusted,
It is exported the first register for being stored with target PPG value adjusted as destination register control PPG signal, and according to first
The value of register is updated the value of the second register;If there are carries/borrow for target PPG value adjusted, by
Two registers are as destination register control PPG signal output.Thus, it is possible to effectively prevent the process adjusted in target PPG value
The PPG value of middle reality output is distorted, and avoids the occurrence of electromagnetic noise, while reducing the risk that IGBT is burnt.
