Description

Technical Field

[0001] The present invention relates to the technical field of heating control, and in particular to a constant temperature heating control method for a heating device and a related device. Background Art

[0002] Electric heating equipment is a common appliance in household facilities. Cooking by electric heating is a common cooking method used by families at present. In order to prevent the ingredients from being burnt, constant temperature heating is required after the heating equipment is heated to a certain degree. In the current constant temperature heating control method of the heating equipment, the temperature of the cooking pot body is usually detected by a temperature sensor, and the temperature of the heating component is not taken into account. Due to long-term operation, the working temperature of the heating component in the heating device increases, making the working state of the heating component unstable, and the working state of the heating component cannot be adjusted in real time according to its working temperature. When the heating device detects that the current real-time temperature is lower than the set target temperature, the adjustment value of the heating power is usually determined only by calculating the error between the real-time temperature and the target temperature, but this will cause a large deviation in the adjustment value. At the same time, due to changes in the internal performance of the component or external disturbances, the constant temperature heating of the heating component will be affected, so that the constant temperature treatment of the heating device cannot achieve the ideal effect, thereby affecting the taste of the cooked ingredients. Summary of the invention

[0060] S15: adjusting the initial heating power to a preset cooling power;

[0061] During the specific implementation of the present invention, when it is detected that the real-time temperature of the heating component is greater than or equal to the target constant temperature, the initial heating power is adjusted to a preset cooling power. The preset cooling power may be 0W or a power smaller than the initial heating power. After being adjusted to the preset cooling power, the real-time temperature of the heating component begins to gradually decrease.

[0064] S17: Determine whether the real-time temperature at the preset cooling power is greater than or equal to the target constant temperature;

[0065] In the specific implementation process of the present invention, the real-time temperature of the heating component when it is at the preset cooling power is compared with the target constant temperature. When it is detected that the real-time temperature is still greater than or equal to the target constant temperature, step S15 is entered to continue to reduce the temperature of the heating component based on the preset cooling power. When it is detected that the real-time temperature is lower than the target constant temperature, step S18 is entered.

[0066] S18: Calculating the temperature difference between the current real-time temperature and the target constant temperature, and calculating the heating power compensation value based on the temperature difference;

[0067] In the specific implementation process of the present invention, the calculation of the heating power compensation value based on the temperature difference includes: calculating the current temperature deviation change rate based on the temperature difference, and fuzzifying the temperature difference and the temperature deviation change rate based on the membership function to obtain the temperature difference fuzzy quantity and the temperature deviation change rate fuzzy quantity; obtaining the temperature change curve of the heating component under the control of PID parameters, and establishing fuzzy rules based on the temperature change curve; establishing a Cauer thermal network model, calculating the order of magnitude relationship between thermal parameters of each order in the Cauer thermal network model, and establishing a mapping relationship between time constants and thermal parameters of each order based on the order of magnitude relationship between thermal parameters of each order; based on the mapping relationship, the temperature difference fuzzy quantity and the temperature deviation change rate fuzzy quantity, a PID fuzzy controller is used in combination with the fuzzy rules to calculate the heating power compensation value.

[0068] Furthermore, the establishment of the Kaoer thermal network model includes: establishing a temperature utility model based on the heating characteristics and heat load characteristics of the heating component; establishing an equivalent thermal parameter model of the heating component based on the temperature utility model, and establishing an objective function and constraints, and establishing the Kaoer thermal network model based on the objective function and constraints using the equivalent thermal parameter model combined with the physical connection structure of the device.

[0069] Furthermore, the temperature difference and the temperature deviation change rate are fuzzy processed based on the membership function to obtain the temperature difference fuzzy quantity and the temperature deviation change rate fuzzy quantity, including: dividing a number of continuous control intervals based on the overall distribution optimization algorithm using the attribute information of the heating component; defining the membership function of each continuous control interval based on the triangular fuzzy membership function; and allocating the temperature difference and the temperature deviation change rate to each continuous control interval based on the membership function for fuzzy processing to obtain the temperature difference fuzzy quantity and the temperature deviation change rate fuzzy quantity.

[0070] Specifically, when it is detected that the second real-time temperature of the heating component is lower than the target constant temperature, the temperature difference between the second real-time temperature and the target constant temperature is calculated at the current moment, and the current temperature deviation change rate is calculated based on the temperature difference, that is, the temperature deviation value is calculated by the temperature difference, and the current temperature deviation change rate is calculated by the temperature deviation value; based on the overall distribution optimization algorithm, the attribute information of the heating component is used to divide a number of continuous control intervals, the attribute information of the heating component is used to divide the bounded domain range, an initial population is randomly generated within the defined domain range, the optimal particle is searched in the population, and a new population is generated within the vicinity of the optimal particle using the Cauchy distribution, the above process is repeated until a preset number of iterations is reached, that is, the convergence condition of the overall distribution optimization algorithm is reached, and the divided several continuous control intervals are obtained, and the boundaries of the interval division are adjusted by the overall distribution optimization algorithm, so that the interval division is more reasonable and the limitations of the mean division are avoided. The membership function of each continuous control interval is defined based on the triangular fuzzy membership function, the fuzzy set of each continuous control interval is listed using the triangular fuzzy membership function, the corresponding semantic variables are described by the fuzzy set of each continuous control interval, and the membership function of the fuzzy set for each continuous control interval is calculated by the corresponding semantic variables. Based on the membership function, the temperature difference and the temperature deviation change rate are allocated to each continuous control interval for fuzzification processing, that is, based on the membership function, the temperature difference and the temperature deviation change rate are allocated to each continuous control interval to create a corresponding sequence of fuzzy relations, and fuzzification processing is performed according to the fuzzy relations of the corresponding sequence to obtain the temperature difference fuzzy quantity and the temperature deviation change rate fuzzy quantity. The temperature change curve of the heating component under the control of proportional-integral-derivative (PID) parameters is obtained, the corresponding data is obtained by simulating the heating component by using PID parameters, the temperature change curve is drawn according to the corresponding data, and then the temperature change curve is stored in a corresponding database, the temperature change curve can be quickly obtained through the corresponding database, fuzzy rules are established based on the temperature change curve, the dynamic characteristics of temperature change are extracted through the temperature change curve, and the adjustment speed rules, static error elimination rules and controller oscillation error elimination rules are set through the dynamic characteristics The adjustment speed rule, static error elimination rule and controller oscillation error elimination rule constitute fuzzy rules. The adjustment speed rule is that when the current real-time temperature is far lower than the target constant temperature, the adjustment speed should be increased to make it reach the target constant temperature as soon as possible. When the current real-time temperature is lower than the target constant temperature, but the difference between it and the target constant temperature is not large, the adjustment speed can be appropriately slowed down. The static error elimination rule is to increase the integral effect in the vicinity of the target constant temperature so that the temperature of the heating equipment can reach the target constant temperature value as soon as possible and stabilize. The controller oscillation error elimination rule is to introduce an early differential control signal to correct the deviation generated by the controller as soon as possible and reduce the possible overshoot.The heating characteristics, heat load characteristics and device physical connection structure of the heating component are obtained from the local database, and a temperature utility model is established according to the heating characteristics and heat load characteristics of the heating component. An equivalent thermal parameter model of the heating component is established according to the temperature utility model, and an objective function and constraint conditions are established. Based on the objective function and constraint conditions, the equivalent thermal parameter model is used to introduce the device physical connection structure to establish a Kaul thermal network model, which is a model that simulates the dynamic coupling of the electrical characteristic model and thermal characteristic description of the electronic device. The order of magnitude relationship between the thermal parameters of each order in the Kaul thermal network model is calculated, and the order of magnitude relationship between the thermal parameters of each order in the Kaul thermal network model is calculated according to the order of magnitude difference between the thermal capacitance and thermal resistance of each order in the Kaul thermal network model; based on the order of magnitude relationship between the thermal parameters of each order, a mapping relationship between the time constant and the thermal parameters of each order is established, that is, a mapping relationship between the time constant and the thermal capacitance and thermal resistance of each order in the Kaul thermal network model is established. Based on the mapping relationship, the temperature difference fuzzy quantity and the temperature deviation change rate fuzzy quantity, the heating power compensation value is calculated using the PID fuzzy controller in combination with the fuzzy rules. The temperature difference fuzzy quantity and the temperature deviation change rate fuzzy quantity are input into the PID fuzzy controller through the fuzzy rules for calculation to obtain the heating power compensation value. The expression of the heating power compensation value is:

[0071]

[0072] Where, u is the heating power compensation value, K P is the proportional value calculated by the PID fuzzy controller, K I is the integral value calculated by the PID fuzzy controller, K D is the integral value calculated by the PID fuzzy controller, is the cumulative error, ec is the temperature deviation change rate fuzzy quantity, ea is the temperature difference fuzzy quantity, σ is the mapping relationship, and the heating power compensation value is the heating power compensation coefficient. The heating power compensation value is calculated using the PID fuzzy controller to control the heating component to perform constant temperature heating treatment and reduce the overshoot of the compensation value. The required heating power compensation value can be obtained with faster efficiency.

[0073] S19: generating a constant temperature heating power based on the heating power compensation value, and controlling the heating component to perform a constant temperature heating process based on the constant temperature heating power.

[0074] In the specific implementation process of the present invention, the constant temperature heating treatment of the heating component is controlled based on the constant temperature heating power, including: in the process of controlling the heating component to perform the constant temperature heating treatment, obtaining the target duty cycle corresponding to the constant temperature heating power, and adjusting the constant temperature heating treatment process of the heating component based on the target duty cycle.

[0075] Furthermore, the method of obtaining a target duty cycle corresponding to the constant temperature heating power and adjusting the constant temperature heating process of the heating component based on the target duty cycle includes: obtaining a correspondence between the analog voltage signal and the duty cycle of each constant temperature heating power value based on a correspondence table; establishing an indirect correspondence between the digital analog signal and the duty cycle; determining the target duty cycle corresponding to the constant temperature heating power of the heating component based on the correspondence and the indirect correspondence; sending a pulse signal to the heating component based on the target duty cycle, and adjusting the constant temperature heating process of the heating component based on the pulse signal.

[0076] Specifically, the heating component is controlled to perform constant temperature heating treatment using feedback parameters based on the heating power compensation value, and the final target output power is calculated by the heating power compensation value and the rated heating power. The heating component is controlled to perform constant temperature heating treatment by the target output power to achieve rapid and reasonable temperature rise. In the process of controlling the heating component to perform constant temperature heating treatment, the correspondence between the analog voltage signal and the duty cycle of each constant temperature heating power value is obtained based on the correspondence table, and the correspondence with the duty cycle can be obtained from the correspondence table of the local database. An indirect correspondence between the digital analog signal and the duty cycle is established, and the digital voltage signal corresponding to the analog voltage signal is determined according to the correspondence, and a brief correspondence between the digital voltage signal and the duty cycle is obtained from the local database. Based on the corresponding relationship and the indirect corresponding relationship, the target duty cycle corresponding to the constant temperature heating power of the heating component is determined. The corresponding relationship between the voltage signal and the digital signal of the constant temperature heating power and the duty cycle can determine the target duty cycle corresponding to the constant temperature heating power. The duty cycle refers to the pulse width modulation duty cycle, and there is no need to monitor the voltage and current in real time to ensure power stability. This not only simplifies the hardware structure of the heating control circuit and reduces the cost, but also improves the reliability of power control. Based on the target duty cycle, a pulse signal is sent to the heating component. The pulse signal is used for pulse width modulation to quickly transmit adjustment data in a very short time. The constant temperature heating treatment process of the heating component is adjusted based on the pulse signal. The constant temperature heating treatment process of the heating component is adjusted using the target duty cycle, which greatly reduces the impact of changes in the internal performance of the component or external disturbances. The error of the constant temperature heating treatment process can be effectively corrected through the target duty cycle, so that the constant temperature heating control of the heating equipment can achieve a more ideal effect.

[0077] S20: When the heating component is in a constant temperature heating process, detecting the real-time temperature of the heating component in the constant temperature heating process based on a temperature sensor;

[0078] In a specific implementation of the present invention, when the heating component is in a constant temperature heating process, the real-time temperature of the heating component in the constant temperature heating process is continuously detected based on a temperature sensor built into the heating component.

[0079] S21: Determine whether the real-time temperature of the heating component during the constant temperature heating process is greater than or equal to the target constant temperature.

[0080] In the specific implementation process of the present invention, it is determined whether the real-time temperature of the heating component during the constant temperature heating process is greater than or equal to the target constant temperature, the real-time temperature of the heating component during the constant temperature heating process is used as the third real-time temperature, the third real-time temperature of the heating component is detected based on a temperature sensor, and before the third real-time temperature is less than the target constant temperature, the temperature difference between the third real-time temperature and the target constant temperature at each moment is calculated based on the third real-time temperature; the heating power compensation value and the target duty cycle at each moment are updated based on the temperature difference between the third real-time temperature and the target constant temperature; the heating component is subjected to constant temperature heating based on the heating power compensation value and the target duty cycle at each moment; After the third real-time temperature is greater than or equal to the target constant temperature, the constant temperature heating power generated by the heating power compensation value at the current moment is adjusted to the preset cooling power. When the heating component is at the preset cooling power again, the fourth real-time temperature of the heating component is detected based on the temperature sensor. When it is detected that the fourth real-time temperature is lower than the target constant temperature, the temperature difference between the fourth real-time temperature and the target constant temperature is calculated, and a new constant temperature heating power is regenerated based on the temperature difference between the fourth real-time temperature and the target constant temperature. Based on the new constant temperature heating power, the heating component is controlled to perform constant temperature heating treatment until the temperature sensor detects that the real-time temperature of the heating component is greater than or equal to the target constant temperature.

[0081] Specifically, it is determined whether the real-time temperature of the heating component during the constant temperature heating process is greater than or equal to the target constant temperature. If the real-time temperature during the constant temperature heating process is greater than or equal to the target constant temperature, the process proceeds to step S15, and the heating power is adjusted to a preset cooling power to reduce the temperature of the heating component. If the real-time temperature during the constant temperature heating process is still less than the target constant temperature, the process proceeds to step S18, and the temperature difference between the real-time temperature at each moment and the target constant temperature is calculated. Based on the temperature difference between the real-time temperature at each moment and the target constant temperature, the heating power compensation value and the target duty cycle at each moment are updated. The heating component is subjected to constant temperature heating based on the heating power compensation value and the target duty cycle. That is, in this process, the third real-time temperature of the heating component is detected based on the temperature sensor. When the third real-time temperature is less than the target constant temperature, the heating power compensation value and the target duty cycle are updated. Before the constant temperature is set, the temperature difference between the third real-time temperature at each moment and the target constant temperature is calculated based on the third real-time temperature; the heating power compensation value and the target duty cycle at each moment are updated based on the temperature difference between the third real-time temperature and the target constant temperature; the heating component is subjected to constant temperature heating treatment based on the heating power compensation value and the target duty cycle at each moment, and the constant temperature heating power in the process is continuously updated by the heating power compensation value at each moment, and then the target duty cycle is continuously updated, and constant temperature heating treatment is performed at different moments based on the continuously updated constant temperature heating power and the target duty cycle. Because the temperature difference changes at all times, the constant temperature heating power is continuously adjusted by continuously updating the temperature difference, so that when the temperature difference is large, the adjusted constant temperature heating power is large, and when the temperature difference begins to become smaller, the adjusted constant temperature heating power is small, so as to achieve rapid heating and ensure that the actual temperature is easier to stabilize. The above processing is repeated to realize the constant temperature heating control of the heating equipment until the user cancels the heating.

[0082] In the embodiment of the present invention, the real-time temperature of the heating component is directly detected by the temperature sensor, so that the working state of the heating component can be adjusted according to the obtained real-time temperature. When it is detected that the real-time temperature of the heating component is lower than the target constant temperature, the PID fuzzy controller is used to calculate the heating power compensation value to control the heating component to perform constant temperature heating treatment, reduce the overshoot of the compensation value, and obtain the required heating power compensation value with faster efficiency. At the same time, the heating power adjusted by the heating power compensation value can be closer to the ideal value, improve the stability of constant temperature control, and effectively reduce temperature fluctuations. At the same time, the constant temperature heating process of the heating component is adjusted by the target duty cycle, which greatly reduces the changes in the internal performance of the component or the influence of external disturbances. Constant temperature control is achieved according to the detected real-time temperature of the heating component, so that the constant temperature heating control of the heating equipment achieves a more ideal effect.

[0094] Furthermore, the establishment of the Kaoer thermal network model includes: establishing a temperature utility model based on the heating characteristics and heat load characteristics of the heating component; establishing an equivalent thermal parameter model of the heating component based on the temperature utility model, and establishing an objective function and constraints, and establishing the Kaoer thermal network model based on the objective function and constraints using the equivalent thermal parameter model combined with the physical connection structure of the device.

[0095] Furthermore, the temperature difference and the temperature deviation change rate are fuzzy processed based on the membership function to obtain the temperature difference fuzzy quantity and the temperature deviation change rate fuzzy quantity, including: dividing a number of continuous control intervals based on the overall distribution optimization algorithm using the attribute information of the heating component; defining the membership function of each continuous control interval based on the triangular fuzzy membership function; and allocating the temperature difference and the temperature deviation change rate to each continuous control interval based on the membership function for fuzzy processing to obtain the temperature difference fuzzy quantity and the temperature deviation change rate fuzzy quantity.

[0096] Specifically, when it is detected that the second real-time temperature of the heating component is lower than the target constant temperature, the temperature difference between the second real-time temperature and the target constant temperature is calculated at this moment, and the current temperature deviation change rate is calculated based on the temperature difference, that is, the temperature deviation value is calculated by the temperature difference, and the current temperature deviation change rate is calculated by the temperature deviation value; based on the overall distribution optimization algorithm, the attribute information of the heating component is used to divide a number of continuous control intervals, the attribute information of the heating component is used to divide the bounded domain range, an initial population is randomly generated within the defined domain range, the optimal particle is searched in the population, and a new population is generated within the vicinity of the optimal particle using the Cauchy distribution, the above process is repeated until a preset number of iterations is reached, that is, the convergence condition of the overall distribution optimization algorithm is reached, and the divided several continuous control intervals are obtained, and the boundaries of the interval division are adjusted by the overall distribution optimization algorithm, so that the interval division is more reasonable and the limitations of the mean division are avoided. The membership function of each continuous control interval is defined based on the triangular fuzzy membership function, the fuzzy set of each continuous control interval is listed using the triangular fuzzy membership function, the corresponding semantic variables are described by the fuzzy set of each continuous control interval, and the membership function of the fuzzy set for each continuous control interval is calculated by the corresponding semantic variables. Based on the membership function, the temperature difference and the temperature deviation change rate are allocated to each continuous control interval for fuzzification processing, that is, based on the membership function, the temperature difference and the temperature deviation change rate are allocated to each continuous control interval to create a corresponding sequence of fuzzy relations, and fuzzification processing is performed according to the fuzzy relations of the corresponding sequence to obtain the temperature difference fuzzy quantity and the temperature deviation change rate fuzzy quantity. The temperature change curve of the heating component under the control of proportional-integral-derivative (PID) parameters is obtained, the corresponding data is obtained by simulating the heating component by using PID parameters, the temperature change curve is drawn according to the corresponding data, and then the temperature change curve is stored in a corresponding database, the temperature change curve can be quickly obtained through the corresponding database, fuzzy rules are established based on the temperature change curve, the dynamic characteristics of temperature change are extracted through the temperature change curve, and the adjustment speed rules, static error elimination rules and controller oscillation error elimination rules are set through the dynamic characteristics The adjustment speed rule, static error elimination rule and controller oscillation error elimination rule constitute fuzzy rules. The adjustment speed rule is that when the current real-time temperature is far lower than the target constant temperature, the adjustment speed should be increased to make it reach the target constant temperature as soon as possible. When the current real-time temperature is lower than the target constant temperature, but the difference between it and the target constant temperature is not large, the adjustment speed can be appropriately slowed down. The static error elimination rule is to increase the integral effect in the vicinity of the target constant temperature so that the temperature of the heating equipment can reach the target constant temperature value as soon as possible and stabilize. The controller oscillation error elimination rule is to introduce an early differential control signal to correct the deviation generated by the controller as soon as possible and reduce the possible overshoot.The heating characteristics, heat load characteristics and device physical connection structure of the heating component are obtained from the local database, and a temperature utility model is established according to the heating characteristics and heat load characteristics of the heating component. An equivalent thermal parameter model of the heating component is established according to the temperature utility model, and an objective function and constraint conditions are established. Based on the objective function and constraint conditions, the equivalent thermal parameter model is used to introduce the device physical connection structure to establish a Kaul thermal network model, which is a model that simulates the dynamic coupling of the electrical characteristic model and thermal characteristic description of the electronic device. The order of magnitude relationship between the thermal parameters of each order in the Kaul thermal network model is calculated, and the order of magnitude relationship between the thermal parameters of each order in the Kaul thermal network model is calculated according to the order of magnitude difference between the thermal capacitance and thermal resistance of each order in the Kaul thermal network model; based on the order of magnitude relationship between the thermal parameters of each order, a mapping relationship between the time constant and the thermal parameters of each order is established, that is, a mapping relationship between the time constant and the thermal capacitance and thermal resistance of each order in the Kaul thermal network model is established. Based on the mapping relationship, the temperature difference fuzzy quantity and the temperature deviation change rate fuzzy quantity, the heating power compensation value is calculated using the PID fuzzy controller in combination with the fuzzy rules. The temperature difference fuzzy quantity and the temperature deviation change rate fuzzy quantity are input into the PID fuzzy controller through the fuzzy rules for calculation to obtain the heating power compensation value. The expression of the heating power compensation value is:

[0097]

[0098] Where, u is the heating power compensation value, K P is the proportional value calculated by the PID fuzzy controller, K I is the integral value calculated by the PID fuzzy controller, K D is the integral value calculated by the PID fuzzy controller, is the cumulative error, ec is the temperature deviation change rate fuzzy quantity, ea is the temperature difference fuzzy quantity, σ is the mapping relationship, and the heating power compensation value is the heating power compensation coefficient. The heating power compensation value is calculated using the PID fuzzy controller to control the heating component to perform constant temperature heating treatment and reduce the overshoot of the compensation value. The required heating power compensation value can be obtained with faster efficiency.

[0099] The constant temperature heating module 25 is used to generate a constant temperature heating power based on the heating power compensation value, and control the heating component to perform a constant temperature heating process based on the constant temperature heating power.

[0100] In the specific implementation process of the present invention, the constant temperature heating treatment of the heating component is controlled based on the constant temperature heating power, and also includes: in the process of controlling the heating component to perform the constant temperature heating treatment, obtaining a target duty cycle corresponding to the constant temperature heating power, and adjusting the constant temperature heating treatment process of the heating component based on the target duty cycle.

[0101] Furthermore, in the process of controlling the heating component to perform constant temperature heating treatment, a target duty cycle corresponding to the constant temperature heating power is obtained, and the constant temperature heating treatment process of the heating component is adjusted based on the target duty cycle, and the process also includes: detecting a third real-time temperature of the heating component based on a temperature sensor, and before the third real-time temperature is less than the target constant temperature temperature, calculating a temperature difference between the third real-time temperature and the target constant temperature at each moment based on the third real-time temperature; updating a heating power compensation value and a target duty cycle at each moment based on the temperature difference between the third real-time temperature and the target constant temperature; performing constant temperature heating treatment on the heating component based on the heating power compensation value and the target duty cycle at each moment; After the third real-time temperature is greater than or equal to the target constant temperature, the constant temperature heating power generated by the heating power compensation value at the current moment is adjusted to the preset cooling power. When the heating component is at the preset cooling power again, the fourth real-time temperature of the heating component is detected based on the temperature sensor; when it is detected that the fourth real-time temperature is lower than the target constant temperature, the temperature difference between the fourth real-time temperature and the target constant temperature is calculated, and a new constant temperature heating power is regenerated based on the temperature difference between the fourth real-time temperature and the target constant temperature. Based on the new constant temperature heating power, the heating component is controlled to perform constant temperature heating treatment until the temperature sensor detects that the real-time temperature of the heating component is greater than or equal to the target constant temperature.

[0102] Furthermore, the method of obtaining a target duty cycle corresponding to the constant temperature heating power and adjusting the constant temperature heating process of the heating component based on the target duty cycle includes: obtaining a correspondence between the analog voltage signal and the duty cycle of each constant temperature heating power value based on a correspondence table; establishing an indirect correspondence between the digital analog signal and the duty cycle; determining the target duty cycle corresponding to the constant temperature heating power of the heating component based on the correspondence and the indirect correspondence; sending a pulse signal to the heating component based on the target duty cycle, and adjusting the constant temperature heating process of the heating component based on the pulse signal.

[0103] Specifically, the heating component is controlled to perform constant temperature heating treatment using feedback parameters based on the heating power compensation value, and the final target output power is calculated by the heating power compensation value and the rated heating power. The heating component is controlled to perform constant temperature heating treatment by the target output power to achieve rapid and reasonable temperature rise. In the process of controlling the heating component to perform constant temperature heating treatment, the correspondence between the analog voltage signal and the duty cycle of each constant temperature heating power value is obtained based on the correspondence table, and the correspondence with the duty cycle can be obtained from the correspondence table of the local database. An indirect correspondence between the digital analog signal and the duty cycle is established, and the digital voltage signal corresponding to the analog voltage signal is determined according to the correspondence, and a brief correspondence between the digital voltage signal and the duty cycle is obtained from the local database. Based on the corresponding relationship and the indirect corresponding relationship, the target duty cycle corresponding to the constant temperature heating power of the heating component is determined. The corresponding relationship between the voltage signal and the digital signal of the constant temperature heating power and the duty cycle can determine the target duty cycle corresponding to the constant temperature heating power. The duty cycle refers to the pulse width modulation duty cycle, and there is no need to monitor the voltage and current in real time to ensure power stability. This not only simplifies the hardware structure of the heating control circuit and reduces the cost, but also improves the reliability of power control. Based on the target duty cycle, a pulse signal is sent to the heating component. The pulse signal is used for pulse width modulation to quickly transmit adjustment data in a very short time. The constant temperature heating treatment process of the heating component is adjusted based on the pulse signal. The constant temperature heating treatment process of the heating component is adjusted using the target duty cycle, which greatly reduces the impact of changes in the internal performance of the component or external disturbances. The error of the constant temperature heating treatment process can be effectively corrected through the target duty cycle, so that the constant temperature heating control of the heating equipment can achieve a more ideal effect.

[0104] In this process, the third real-time temperature of the heating component is detected based on the temperature sensor. Before the third real-time temperature is lower than the target constant temperature, the temperature difference between the third real-time temperature and the target constant temperature at each moment is calculated based on the third real-time temperature; the heating power compensation value and the target duty cycle at each moment are updated based on the temperature difference between the third real-time temperature and the target constant temperature; the heating component is subjected to constant temperature heating treatment based on the heating power compensation value and the target duty cycle at each moment, the constant temperature heating power in the process is continuously updated by the heating power compensation value at each moment, and then the target duty cycle is continuously updated, and constant temperature heating treatment is performed at different moments based on the continuously updated constant temperature heating power and target duty cycle. Since the temperature difference changes at all times, the constant temperature heating power is continuously adjusted by continuously updating the temperature difference, so that when the temperature difference is large, the adjusted constant temperature heating power is large, and when the temperature difference begins to become smaller, the adjusted constant temperature heating power is small, so as to achieve rapid heating and ensure that the actual temperature is more easily stabilized. After the third real-time temperature is greater than or equal to the target constant temperature, the constant temperature heating power generated by the heating power compensation value at the current moment is adjusted to the preset cooling power. When the heating component is at the preset cooling power again, the fourth real-time temperature of the heating component is detected based on the temperature sensor; when the fourth real-time temperature is detected to be less than the target constant temperature, the temperature difference between the fourth real-time temperature and the target constant temperature is calculated, and a new constant temperature heating power is regenerated based on the temperature difference between the fourth real-time temperature and the target constant temperature. Based on the new constant temperature heating power, the heating component is controlled to perform constant temperature heating until the temperature sensor detects that the real-time temperature of the heating component is greater than or equal to the target constant temperature. When the real-time temperature of the heating component is detected to be greater than or equal to the target constant temperature again, the heating power is adjusted again, and the real-time temperature of the heating component is detected. When the real-time temperature of the heating component is detected to be less than the target constant temperature again, the heating power compensation value is calculated again to adjust the heating power to perform constant temperature heating until the temperature of the heating component is greater than or equal to the target constant temperature again. The above process is repeated to realize the constant temperature heating control of the heating device.

[0105] In the embodiment of the present invention, the real-time temperature of the heating component is directly detected by the temperature sensor, so that the working state of the heating component can be adjusted according to the obtained real-time temperature. When it is detected that the real-time temperature of the heating component is lower than the target constant temperature, the PID fuzzy controller is used to calculate the heating power compensation value to control the heating component to perform constant temperature heating treatment, reduce the overshoot of the compensation value, and obtain the required heating power compensation value with faster efficiency. At the same time, the heating power adjusted by the heating power compensation value can be closer to the ideal value, improve the stability of constant temperature control, and effectively reduce temperature fluctuations. At the same time, the constant temperature heating process of the heating component is adjusted by the target duty cycle, which greatly reduces the changes in the internal performance of the component or the influence of external disturbances. Constant temperature control is achieved according to the detected real-time temperature of the heating component, so that the constant temperature heating control of the heating equipment achieves a more ideal effect.
