Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
In the related art, a fixed single cycle is usually adopted for compensation heating, and fig. 1 is a schematic diagram of cycle heating in the prior art provided by an embodiment of the present invention, where a is a heating cycle, P is a heating duty ratio, T0 is a target temperature value, and T is a real-time temperature. When the system reaches the heater on condition, the heater is periodically operated at a heating duty cycle P (where on for X seconds and off for Y seconds). According to the heat transfer principle, the larger the temperature difference, the faster the heat transfer, and the temperature difference between the temperature of the compensation heating device and the target temperature is dynamically changed, and the heating is carried out when the temperature value is reduced to be lower than the target temperature value, so that the heating efficiency in part of time is lower.
The first embodiment is as follows:
in order to at least solve the technical problem proposed in the present invention, an embodiment of the present invention provides a method for determining a temperature control parameter.
Fig. 2 is a schematic flow chart of a method for determining a temperature control parameter according to an embodiment of the present invention, and referring to fig. 2, the method for determining a temperature control parameter according to an embodiment of the present invention may include the following steps:
s21, heating and operating at a preset duty ratio, acquiring a first temperature value of the target object, determining the heating and operating time length as a first heating time length if the first temperature value reaches a temperature threshold value, and stopping heating for the first cooling time length;
s22, acquiring a second temperature value of the target object, judging whether the second temperature value is lower than the target temperature value, and if the second temperature value is lower than the target temperature value, continuing to heat and operate at a preset duty ratio; the temperature threshold is higher than the target temperature value;
and S23, taking the first heating time period and the first cooling time period as temperature control parameters.
Specifically, the temperature control parameter may be determined, and when the temperature control parameter is determined, a preset duty cycle may be determined, for example, the preset duty cycle may be X: y, namely the heating time length X, stopping the heating time length Y, controlling the heater to heat and operate at the preset duty ratio after the preset duty ratio is determined, collecting a first temperature value of the target object, and stopping the heating of the heater after the time length of the heating operation of the heater in the period is determined to be the first heating time length X1 when the first temperature value reaches the temperature threshold value, and stopping the first cooling time length Y1. When the heater is operated above the target temperature, the time for decreasing the heater to the target temperature is fixed, and at this time, the heater temperature can be effectively maintained above the target temperature by increasing the heater operation time X1.
The temperature threshold is set to be higher than the target temperature value, and under an ideal condition, the smaller the temperature difference between the temperature threshold and the target temperature value is, the smaller the heat loss is.
According to the temperature control parameter determining method provided by the embodiment of the invention, the heater is controlled to heat and operate at the preset duty ratio, when the acquired first temperature value of the target object reaches the temperature threshold value, the first heating time length is determined, and the first cooling time length is stopped being heated, so that when the heater operates above the target temperature, the time for reducing the temperature to the target temperature is fixed, and at the moment, the temperature of the heater can be effectively maintained above the target temperature by increasing the first heating time length for operating the heater.
In some embodiments, optionally, the method further includes: if the second temperature value is not lower than the target temperature value, determining the time length shorter than the first heating time length as a second heating time length, and stopping heating for the second cooling time length after heating and operating the second heating time length at the preset duty ratio;
acquiring a third temperature value of the target object, and judging whether the third temperature value is lower than the target temperature value or not;
if the third temperature value is not lower than the target temperature value, taking the shortened second heating time as the next second heating time, heating and operating the second heating time again at the preset duty ratio, and determining each second heating time; each second heating period and each second cooling period are used as temperature control parameters.
Specifically, a time period less than the first heating time period X1 may be determined as the second heating time period X2, and after the heater continues to operate for X2 time period at the preset duty ratio, the heater is stopped to heat, and the second cooling time period Y2 is stopped to heat. And acquiring the temperature of the target object at the moment as a third temperature value, if the third temperature value is still higher than or equal to the target temperature value, performing heat compensation on the heater, taking the shortened second heating time period as a second heating time period, and heating again until the third temperature value is lower than the target temperature value, so that the operation time of the heater is as short as possible, and the time for keeping the temperature value above the target temperature value is as long as possible.
Recording the first heating duration, the first cooling duration, each second heating duration and each second cooling duration as temperature control parameters.
According to the temperature control parameter determining method provided by the embodiment of the invention, the temperature control parameters are determined through multi-cycle heating, so that the operation time of the heater is as short as possible, and the time for keeping the temperature value above the target temperature value is as long as possible, the heating operation efficiency is improved, and the heating operation energy consumption is reduced.
In some embodiments, the second heating time period after the shortening is optionally used as the next second heating time period, and the method includes: determining a shortening interval; shortening the second heating period according to the shortened interval; the second heating time after the shortening is taken as the next second heating time.
For example, the corresponding shortening interval may be set as desired.
In some embodiments, optionally, the method further includes:
prolonging the first heating time according to the required temperature rise rate of the target object;
the rate of temperature rise required is proportional to the extended first heating period.
For example, when the required temperature rise rate is high, the first heating time period can be correspondingly prolonged, and the heater can quickly reach the temperature threshold value through intensive heating.

based on a general inventive concept, an embodiment of the present invention also provides a temperature control method.

and S31, heating and running for a first heating time period at a preset duty ratio, and stopping heating for a first cooling time period.

In a specific temperature control process, heating may be controlled according to the temperature control parameters such as the first heating period, the first cooling period, each second heating period, and each second cooling period determined in the above embodiments. When only the first heating period and the first cooling period temperature control parameters are included, only the heating is controlled in step S31 alone. The heating is controlled through step S31 and step S32, including the first heating period, the first cooling period, each second heating period, and each second cooling period.

When the requirement on the heating efficiency is higher, three or more heating cycles can be set, the temperature is quickly increased to be higher than the target temperature through intensive heating in the X1 stage, the heating is stopped, the temperature is slowly reduced, and the heating enters the X2 and X3 stages for heat compensation along with the change of the temperature difference between the heater and the target temperature, so that the purposes that the operation time of the heater is as short as possible, and the temperature is maintained to be higher than the target temperature for a longer time are achieved.
