Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
Example 1
Fig. 1 is a flowchart of a method for controlling a rotational speed of a circulation pump according to an embodiment of the present application.
As shown in fig. 1, the rotation speed control method provided in the embodiment is applied to an electronic device, and is used for controlling the rotation speed of a circulation pump of an internal combustion engine, so that the internal combustion engine obtains a better heat dissipation effect. The electronic device herein may be understood as a computer or an embedded device having data computing and information processing capabilities, such as an MCU or ECU of the internal combustion engine. The circulation pump is generally driven by a motor, and thus the control of the rotation speed of the circulation pump herein substantially controls the rotation speed of the motor driving the circulation pump, and the rotation speed control method of the present embodiment includes the steps of:
s1, calculating a difference value between the current boiling point of the cooling liquid in the current environment and the standard boiling point of the cooling liquid.
The difference in boiling points, which is referred to in this example, is obtained by calculating the difference in the two boiling points. The current boiling point refers to the boiling point of the coolant at the atmospheric pressure in the current environment, the current environment refers to the environment of the current location of the internal combustion engine, and the normal boiling point refers to the boiling point of the coolant at atmospheric pressure, which generally refers to the atmospheric pressure at sea level. The method is realized by the following steps:
first, the atmospheric pressure in the current environment is acquired, and it is generally acquired by a barometer provided on the internal combustion engine.
Then, the atmospheric pressure P is calculated according to the equation An Tuoni to obtain the current boiling point corresponding to the atmospheric pressure. An Tuoni (Antoine) equation is: log p=a-B/t+c, where A, B, C is a constant and is determined by the engine using coolant, T is the current boiling point.
And finally, calculating the difference between the current boiling point and the standard boiling point to obtain a boiling point difference. For a particular coolant, the normal boiling point at normal atmospheric pressure is a fixed value, which can be measured for the coolant at normal atmospheric pressure.
S2, acquiring an initial set temperature of the cooling liquid.
The initial set temperature of the coolant is obtained based on a preset rotation speed-load factor map. The map is essentially a table in which, for the respective rotational speeds and the load factors corresponding to the rotational speeds, there is a corresponding set temperature value which is accumulated by experiments on different configuration parameters of the internal combustion engine. After the current rotation speed and the load factor are determined, a corresponding set temperature value can be found from the current rotation speed and the load factor to serve as the initial set temperature. The specific process is as follows:
first, the current rotational speed and the current load factor of the internal combustion engine are acquired.
Then, searching from the map based on the current rotation speed and the current load factor, thereby obtaining the initial set temperature.
And S3, calculating the current set temperature based on the current set temperature and the boiling point temperature difference.
That is, after the initial set temperature is determined, the current set temperature of the coolant is obtained by subtracting the boiling point difference from the initial set temperature.
And S4, driving the circulating pump to rotate based on the target rotating speed matched with the current set temperature.
Namely, the circulating pump of the internal combustion engine is controlled to rotate at a target rotating speed corresponding to the current set temperature, so that the internal combustion engine achieves a good heat dissipation effect. The specific process is as follows:
first, the current temperature of the cooling liquid is obtained, and the temperature difference between the current set temperature and the current temperature, that is, the difference between the current set temperature and the current temperature is calculated, may be positive or negative, that is, the current temperature may be higher or lower than the current set temperature, may be obtained from a temperature sensor provided in the cooling liquid phase region.
Then, the temperature difference is multiplied by a preset proportionality constant m to obtain a target rotating speed n, namely the ideal rotating speed of the circulating pump. The setting of the proportionality constant m is determined based on the performance of the circulating pump, different circulating pumps correspond to different performances, and the proportionality constant can be obtained through the performance curve of the circulating pump and corresponding actual measurement.
And finally, driving the circulating pump to rotate according to the target rotating speed. In specific implementation, an instruction, such as a frequency converter, can be sent to a corresponding controller based on the target rotation speed, so that the frequency converter drives an electrode connected with the circulating pump to rotate according to the target rotation speed, namely, drives the circulating pump to rotate according to the target rotation speed.
As can be seen from the above technical solution, the present embodiment provides a method for controlling the rotational speed of a circulation pump, which is applied to an electronic device, and is used for controlling the rotational speed of the circulation pump of an internal combustion engine, specifically, calculating a boiling point difference between a current boiling point of a coolant of the internal combustion engine in a current environment and a normal boiling point of the coolant under normal atmospheric pressure; acquiring an initial set temperature of the cooling liquid; subtracting the boiling point difference value from the initial set temperature to obtain the current set temperature of the cooling liquid; the circulation pump is driven to rotate based on a target rotation speed matched with the current set temperature. According to the scheme, the circulating pump can drive the cooling liquid to circulate according to the rotating speed matched with the working condition of the internal combustion engine instead of the constant rotating speed, so that the internal combustion engine can obtain a good heat dissipation effect.

The fourth calculation unit is used for multiplying the temperature difference value by a preset proportionality constant m to obtain a target rotating speed n, namely the ideal rotating speed of the circulating pump. The setting of the proportionality constant m is determined based on the performance of the circulating pump, different circulating pumps correspond to different performances, and the proportionality constant can be obtained through the performance curve of the circulating pump and corresponding actual measurement.
