Background
The method of controlling the temperature by driving the heater based on the dc voltage generally includes fixing a voltage value of a dc power supply, starting heating when a temperature measurement value is lower than a temperature setting value, and stopping heating when the temperature measurement value is higher than the temperature setting value. The method is simple and is commonly used in the field with low requirement on temperature control and temperature stability. The second method is also a method for fixing the voltage value of a direct current power supply, but the average heating power is adjusted by adjusting the duty ratio of the on time of the direct current power supply in unit time (commonly known as a PWM method), and temperature control is realized by matching with a certain temperature control algorithm, so that the method has the advantages that the resolution and the stability of the adjustment of the heating power are higher compared with those of the first method, and the defects that more peak electromagnetic interference can be generated due to the fact that the direct current power supply is continuously switched on and off in a short time, and the method cannot be used in the field sensitive to the electromagnetic interference; the third method is to adopt a program-controlled direct-current power supply, change the magnitude of heating power by adjusting the magnitude of output voltage, and realize temperature control by matching with a certain temperature control algorithm, and the method has the advantages that electromagnetic interference is much smaller than that of the former two methods, and has the defect that when the heating current is larger, the method is limited by limited voltage resolution (generally 0.01V-0.1V), so that the temperature is difficult to be stabilized to a temperature set value, and larger jitter is generated near the temperature set value.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flow chart of an embodiment of the method of the present application.
Step 11, measuring an object to be controlled in temperature to obtain a temperature measurement value, and obtaining an ideal value of the driving voltage of the heater through a temperature control algorithm according to the difference between the temperature measurement value and a temperature set value;
preferably, the temperature control algorithm is a PID algorithm. The algorithm in the prior art is generally realized in a temperature control algorithm, the output voltage is gradually adjusted by observing the change of the target temperature, so that the period is longer, the balance is not easy to adjust, and the disturbance is larger even if the balance is adjusted.
Step 12, setting a discrete sequence of driving voltage values, and directly setting the driving voltage values as discrete values closest to the ideal values when the difference between the temperature set value and the temperature measured value is greater than a first set threshold value;
here, when the difference is greater than the first set threshold, the distance is long, and if it is higher than the target temperature, heating is not performed, and if it is lower than the target temperature, heating is performed at full power. Even with the above adjustments, the results are the same.
The first set threshold here generally means a setting of ± 2K or more.
For example, a commonly used temperature control algorithm (e.g., PID algorithm) is first used to calculate a required temperature control voltage, and when the temperature measurement value is far from the temperature setting value, the voltage value that the program-controlled dc power supply can output is set according to a rounding method regardless of whether the program-controlled dc power supply can output the accuracy required for meeting the temperature control voltage.
Step 13, according to the set discrete sequence of the driving voltage values, when the temperature set value and the temperature measured value are smaller than a second set threshold value, two discrete values adjacent to the ideal value are taken, and the driving voltage values are changed in a PWM mode;
the PWM method is to control the on-time of a plurality of dc power supplies according to a set duty ratio, and the generated average voltage and current meet the target requirements. When the PWM method is used, two adjacent dc voltages are switched, and since the voltage variation is small, the electromagnetic interference introduced by the voltage variation is much smaller than that of the conventional method. In addition, because the difference value between the temperature set value and the temperature measured value is smaller than the second set threshold value, the difference between the two adjacent direct current voltages is smaller.
When the required temperature control voltage calculated by the temperature control algorithm is between two adjacent voltages which can be output by the program-controlled direct-current power supply, the percentage of the two adjacent voltages in unit time is controlled by referring to a PWM method, so that the average voltage in unit time is equal to the required temperature control voltage.
In a special case, when the temperature measurement value is close to the temperature set value, the voltage is set directly if the required voltage value calculated by the temperature controller can be output on the programmable dc power supply.
And step 14, controlling a heating or refrigerating device by using the driving voltage, and adjusting the temperature of the temperature-controlled object to enable the temperature measured value to approach the temperature set value.
It should be noted that the above steps 11 to 14 can be executed circularly.
Preferably, when the driving voltage value is changed by the PWM method, the duty ratio of the two discrete values is changed so that the temperature measurement value approaches the temperature set value.
Fig. 2 is a schematic view of an embodiment of the apparatus of the present application.
The present embodiment further provides a device for improving stability of temperature control, which is used to implement the method according to any embodiment of the present application, and the device includes a dc power supply, a temperature controller, a heater, and a temperature sensor.
In the application, an object needing temperature control is called as a temperature-controlled object;
the temperature sensor is used for cooperating with the temperature controller to obtain the temperature measurement value. For example, the temperature sensor is used for measuring the actual temperature of the temperature-controlled object in cooperation with the temperature controller and transmitting the measurement result to the temperature controller.
And the temperature controller is used for obtaining an ideal value of the driving voltage of the heater through a temperature control algorithm according to the difference between the temperature measured value and the temperature set value. For example, the temperature controller is used for calculating the required programmed direct current power supply set voltage according to the temperature set by the user and the temperature measured value. And when the temperature set value and the temperature measured value are smaller than a second set threshold value, the temperature controller sets the output voltage of the program-controlled direct-current voltage source in a PWM mode.
And the direct current power supply is used for outputting the driving voltage according to the discrete sequence of the driving voltage values. For example, in this embodiment, the dc power supply is a programmable dc power supply. Using a program-controlled direct-current power supply for outputting a direct-current voltage signal according to a voltage setting command of a temperature controller for driving a heater;
the heater is used for converting the electric energy provided by the program-controlled direct-current power supply into heat energy;
the embodiment aims at the current problem and establishes a system for improving the stability of temperature control. The temperature controller calculates the output voltage required by the program-controlled direct-current power supply according to the temperature set value and the temperature measured value, and when the temperature measured value is far away from the temperature set value, the voltage value which can be output by the program-controlled direct-current power supply is set according to a rounding method no matter whether the program-controlled direct-current power supply can output the voltage value with the required precision or not. When the temperature measured value is close to the temperature set value, if the required voltage value calculated by the temperature controller can be output on the program-controlled DC power supply, the voltage is directly set, and when the required voltage calculated by the temperature controller is between two adjacent voltages which can be output by the program-controlled DC power supply, the percentage of the two adjacent voltages in unit time is controlled by referring to a PWM method, so that the average voltage in unit time is equal to the required voltage. When the so-called PWM method is used at the same time, switching is performed between two adjacent dc voltages, because the voltage variation is small and the electromagnetic interference introduced by the voltage variation is much smaller than in the conventional method.
Fig. 3 is a schematic view of another embodiment of the apparatus of the present application.
The embodiment provides a system for improving the stability of temperature control aiming at the current problem. The device for improving the stability of temperature control provided by this embodiment is used to implement the method described in any one of the embodiments of this application, and the device includes a dc power supply, a temperature controller, a heater, and a temperature sensor. The temperature sensor is used for matching with the temperature controller to obtain the temperature measurement value. And the temperature controller is used for obtaining an ideal value of the driving voltage of the heater through a temperature control algorithm according to the difference between the temperature measured value and the temperature set value. And the direct current power supply is used for outputting the driving voltage according to the discrete sequence of the driving voltage values.
Different from the previous embodiment, in this embodiment, the dc power supply is a plurality of dc voltage source modules, and each dc voltage source module outputs one of the voltage values according to the discrete sequence of driving voltage values. And the temperature controller controls the multi-path selection switch in a PWM mode, respectively conducts the two direct-current voltage source modules and respectively outputs two discrete values adjacent to the ideal value.
For example, the system comprises a temperature controller, a first direct current power supply module 1, a second direct current power supply module 2, a multi-way selection switch, a heater, a temperature-controlled object and a temperature sensor, wherein,
and the temperature sensor is used for measuring the actual temperature of the temperature-controlled object in cooperation with the temperature controller and transmitting the measurement result to the temperature controller.

the temperature controller calculates a required heater driving voltage value according to the temperature set value and the temperature measured value, and controls the multi-way selection switch to gate the channel 1 when the required heater driving voltage value is higher than the voltage of the direct-current power supply module 1; when the voltage of the direct current power supply module 2 is lower than the voltage of the direct current power supply module, the temperature controller controls the multi-path selection switch to gate the 3 channel; when the voltage value of the direct current power supply module 1 is between the voltage value of the direct current power supply module 2, the percentage of the two voltages in unit time is controlled by referring to a PWM wave method, so that the average voltage of the two voltages in unit time is equal to the required voltage, and the higher temperature control stability is convenient to realize. When the so-called PWM method is used at the same time, switching is performed between two adjacent dc voltages, because the voltage variation is small and the electromagnetic interference introduced by the voltage variation is much smaller than in the conventional method.

According to the method, by combining the direct-current power supply and the PWM control mode, the problem of large electromagnetic interference of the traditional PWM is solved, and meanwhile, the resolution of power control is improved by adjusting the time ratio of large voltage to small voltage in unit time, so that temperature control oscillation caused by insufficient voltage resolution of the program-controlled direct-current power supply is reduced. The invention not only utilizes the advantage of small interference of the programmed DC power supply in heating temperature control, but also overcomes the defect of temperature control oscillation under certain conditions caused by low voltage resolution of the programmed DC power supply.
