Description

Technical Field

[0001] This application relates to the field of engine heat dissipation, and particularly to an oil vehicle cooling control system, method and device. Background Art

[0002] As Figure 1 shown, when the existing oil vehicle dissipates heat from the engine, it usually dissipates heat from the engine through a separate air radiator (electric fan) provided on the engine. When the engine is running, the air radiator will start to work, and the engine and the air radiator are powered by the same generator. This results in that when the engine is at a high speed, the rotation speed of the air radiator will be limited, thus resulting in a low heat dissipation capacity of the air radiator and a low adaptability to various working conditions.

[0021] To make the objectives, technical solutions and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0022] The technical solutions provided by each embodiment of this application will be described in detail below with reference to the drawings.

[0023] Figure 2 The structural schematic diagram of an oil truck cooling control system provided for one or more embodiments of this specification includes a power supply module, a wind radiator module, an in-vehicle temperature monitoring module, and a control module. Among them, the power supply module supplies power to the wind radiator module through an independent generator. The wind radiator module includes a first wind radiator group and a second wind radiator group. Here, the first wind radiator group is connected to the intercooling component and is used for cooling the intercooling component; the second wind radiator group is connected to the water cooling component and is used for cooling the water cooling component; both the first wind radiator group and the second wind radiator group contain at least one wind radiator, and the specific quantity can be set according to the type of the engine. For example Figure 3 In the shown structural diagram of the wind radiator module, the first wind radiator group is the two wind radiators on the left, which are used to cool the intercooling component, and the second wind radiator group is the four wind radiators on the right, which are used to cool the water cooling component. The in-vehicle temperature monitoring module is used to monitor the temperatures of the intercooling component and the water cooling component. The control module is used to control the power supply module to supply power to the wind radiator module according to the temperatures of the intercooling component and the water cooling component. It should be noted that when the control module controls the power supply of the wind radiator module, the power supply amounts of the first wind radiator group and the second wind radiator group may be different, and the power supply amounts of different wind radiators within the wind radiator group may also be different, that is, the rotation speeds of different wind radiators can be different at the same moment. For example, when the intercooling temperature is higher than the water cooling temperature, the power supply amount of the first wind radiator group can be increased to increase the power of the wind radiators within the first wind radiator group.

[0024] In one embodiment, in order to achieve precise control of cooling, the influence of environmental factors also needs to be considered, such as environmental temperature, humidity, natural wind speed, etc. Therefore, the oil truck cooling control system further includes an environmental monitoring module. Here, the environmental monitoring module includes an environmental temperature monitoring module and an environmental wind speed monitoring module, and a humidity module can also be set. Among them, the environmental temperature monitoring module is used to monitor the environmental temperature of the target vehicle, and the environmental wind speed monitoring module is used to monitor the air flow rate flowing through the engine group. The air flow rate can be measured when the wind radiator module of the target oil truck is not working and used as the air flow rate within a short period of time. The environmental wind speed monitoring module can also be set at the air inlet or outlet of the air duct to monitor the air flow volume at the air inlet and outlet in real time, and subtract the air inflow or outflow caused by the operation of the wind radiator module from the power of the wind radiator module to obtain the natural wind speed. If environmental factors are considered, at this time, the control module needs to control the power supply module to supply power to the wind radiator module according to the temperatures of the intercooler component and the water radiator component, the environmental temperature, and the air flow rate.

This method is applied to the above-mentioned oil truck cooling control system, and this process can be executed by the control module in the system. Some input parameters or intermediate results in the process allow manual intervention and adjustment to help improve accuracy.

[0026] The implementation of the analysis method involved in the embodiments of this application can be a terminal device or a server, and this application does not make special restrictions on this. For the convenience of understanding and description, the following embodiments will be described in detail using the server as an example.

[0027] It should be noted that this server can be a single device or a system composed of multiple devices, that is, a distributed server, and this application does not make specific limitations on this.

[0028] As Figure 4 shown, the embodiments of this application provide an oil truck cooling control method, including:

[0029] S401: Obtain the current temperature of the intercooler component and / or the water radiator component.

[0030] First, through the in-vehicle temperature monitoring module in the oil truck cooling control system, obtain the current temperature of the component that needs to be cooled. When monitoring, either the current temperature of the intercooler component can be monitored only, or the current temperature of the water radiator component can be monitored only, or the current temperatures of both the intercooler component and the water radiator component can be monitored simultaneously. Monitor the component that needs to be cooled.

[0031] S402: Determine the ideal rotation speed of the wind radiator module based on the current temperature.

[0032] After obtaining the current temperature of the component to be cooled, based on the current temperature, the ideal temperature range of the engine, and the pre-established cooling strategy, the ideal rotational speeds of different air radiators at each time point can be determined to cool the component to be cooled from the current temperature to the ideal temperature range.

[0033] In one embodiment, since the cooling principle of the air radiator is to drive air flow through the rotation of the fan blades, and conduct heat exchange with the component to be cooled, thereby reducing the temperature of the component to be cooled. Therefore, when determining different ideal rotational speeds, it is necessary to determine the required air flow rate of the component to be cooled. The required air flow rate here refers to the air flow rate required to cool the component to be cooled from the current temperature to the ideal temperature range. Additionally, when determining the ideal rotational speed, the reserved adjustment time for reducing the current temperature of the target component to be cooled to the ideal temperature range also needs to be considered. If the reserved adjustment time is short, even if the required air flow rate is the same, the rotational speed will be different.

[0034] In summary, when determining the ideal rotational speed, first, the temperature change value of the target component to be cooled within a unit time period is determined; and based on the temperature change value, the temperature value to be adjusted of the target component to be cooled is determined; then, based on the temperature value to be adjusted, the reserved adjustment time of the target component to be cooled is determined; according to the temperature value to be adjusted and the reserved adjustment time, the required air flow rate of the target component to be cooled within the reserved adjustment time is determined; finally, based on the required air flow rate and the reserved adjustment time, the ideal rotational speed of the air radiator module is determined.

[0035] In one embodiment, to avoid frequent calculation and generation of control instructions, the temperature can be monitored and adjusted at preset time intervals. To increase the accuracy, the temperature change within a certain future time period can be predicted based on the current temperature at different time nodes and the driving conditions of the vehicle. Then, according to the predicted value, a control strategy for the future time period can be generated, thereby reducing the adjustment frequency of the control strategy and preventing equipment damage caused by sudden power changes. At this time, the temperature change value of the target component to be cooled within a unit time period can be determined, such as the temperature change value per second. If the temperature change value is relatively low, less computing resources can be used for prediction and the prediction accuracy is relatively high. If the temperature change value is relatively high, the prediction accuracy is relatively low when making a prediction, and only the current temperature of the equipment to be cooled is compared with the ideal temperature range to calculate the temperature to be adjusted at the current time node. Further, when determining the temperature to be adjusted based on the temperature change value within a unit time, if the temperature change value is higher than the preset threshold, the temperature value to be adjusted at the current time is determined based on the current temperature and the ideal temperature range of the target component to be cooled; if the temperature change value is lower than the preset threshold, the predicted temperature value of the target component to be cooled within a future time period is determined according to the temperature change value within the unit time period; based on the predicted temperature value and the ideal temperature range, the temperature adjustment curve of the target component to be cooled within the future time period is determined. When making a prediction, it can be achieved through models such as a neural network model or a support vector machine model. The constructed resource prediction model is pre-trained with a training data set. When the set training accuracy and accuracy are reached, it is determined that the resource prediction model for the current training is completed and can be used for prediction processing.

[0036] In one embodiment, when determining the reserved adjustment time of the target component to be cooled according to the temperature value to be adjusted, the reserved adjustment time of the target component to be cooled at the current time can be determined based on the preset emergency level where the temperature value to be adjusted is located. For example, when the temperature is 50°C higher than the ideal temperature range, to adjust the temperature as soon as possible, the reserved adjustment time can be set to 2s. When the temperature is 10°C higher than the ideal temperature range, although it is not within the ideal temperature range, the slightly exceeded temperature will not affect the operation of the equipment, and the reserved adjustment time can be set slightly longer, such as 4s.

[0037] In one embodiment, since the air radiator is decoupled from the engine, the situation where the air radiator operates as soon as the engine starts will no longer occur, and better effects can be achieved under special working conditions. For example, when the engine is just started and is in the warm-up state, it is necessary for the engine to reach the ideal temperature range as soon as possible to shorten the warm-up time and fuel consumption. Therefore, when it is determined that the temperature is lower than the ideal temperature range, the predicted time point when the temperature of the target component to be cooled reaches the ideal temperature range can be determined based on the temperature change value of the target component to be cooled within a time period, and the air radiator module can be turned off during the period from the current moment to the predicted time point. Finally, at the predicted time point, the temperature data of the target component to be cooled is collected again to achieve the effect of rapid warm-up.

[0038] In one embodiment, when determining the required air flow rate, since the heat exchange value of a unit of air with an engine at the same temperature is different at different temperatures and humidities, the influence of environmental factors needs to be considered. Specifically, first, based on the environmental temperature, the heat exchange value of each unit volume of air is determined, and then based on the temperature value to be adjusted and the reserved adjustment time, the required heat exchange value of the target component to be cooled within the reserved adjustment time is determined; finally, based on the air flow rate of natural wind, the heat exchange of each unit volume of air, and the required heat exchange value, the required air flow rate of the target component to be cooled within the reserved adjustment time can be determined. Among them, when determining the heat exchange value of a unit volume of air based on the environmental temperature, the heat that can be carried away by a unit, such as 1L of air, when it exchanges heat with engines at different temperatures under different environmental temperatures, different humidities, and different flow rates can be determined in advance through experiments, and the specific heat value can be calculated by comparing the temperature difference of the air before and after. When determining the required heat exchange value of the target engine within the reserved adjustment time, it can be calculated through the temperature difference to be adjusted and the specific heat capacity of the component to be cooled. Here, the required heat exchange value of the component to be cooled is equal to the air flow rate corresponding to the newly added power of the air radiator within the reserved adjustment time. Therefore, the required air flow rate within the reserved adjustment time can be calculated.

[0039] Further, after determining the required air flow rate, since the air radiator module includes multiple air radiator groups, and each air radiator group includes multiple air radiators. Therefore, the required air flow rate can be achieved by distributing different powers to different air radiators. At this time, multiple heat dissipation schemes can be generated based on the required air flow rate, and in each heat dissipation scheme, the rotation speeds of the air radiators are different;

[0040] The reward functions corresponding to the multiple heat dissipation schemes are determined through the following formula:

[0041]

[0042] Among them, is the reward function; Denote the i-th air radiator group; j denotes the j-th air radiator within the air radiator group; n is the number of air radiator groups; m is the number of air radiators within the air radiator group; is the heat dissipation coefficient corresponding to the j-th air radiator in the i-th air radiator group, which is used to correct the heat dissipation efficiency of different air radiators at the same rotational speed and reflect the heat dissipation weight of different air radiators; L and b are preset constants; is the rotational speed of the j-th air radiator in the i-th air radiator group; its constraint function is:

[0043]

[0044] where, is the air duct area corresponding to the j-th air radiator in the i-th air radiator group, and P is the required air flow rate. Through the above method, the reward function corresponding to each heat dissipation scheme can be calculated, and finally heat dissipation can be performed based on the heat dissipation scheme with the highest reward function value.

[0045] In one embodiment, when determining the heat dissipation coefficients corresponding to different air radiators, it is necessary to consider the weight of the air radiator group where the air radiator is located, as well as the influence of the installation position and the rotational speeds of other air radiators on this air radiator.

[0046] Specifically, when considering the weight of the air radiator group, it is necessary to consider which component needs to be cooled down under the current working conditions. For example: when the ambient temperature is too high, the cooling of the intercooler component should be considered first, and at this time, the power supply of the air radiators within the first air radiator group corresponding to the intercooler component should be considered first. When the ambient temperature is low, the heat dissipation of the water radiator component is considered first. In addition to the above ambient temperature, the load of the target vehicle and the current temperature of the water radiator component should also be considered. Among them, the higher the current load and the current temperature of the water radiator component, the higher the weight corresponding to the second air radiator group. For example, the first heat dissipation weight of the first air radiator group can be determined by the following formula:

[0047]

[0048] where, is the first heat dissipation weight of the first air radiator group, is a preset coefficient, is the ambient temperature, G is the current load, R is the temperature of the water radiator component, and d is a preset correction constant. After determining the first heat dissipation weight of the first air radiator group, the first heat dissipation weight of the second air radiator group can be determined through .

[0049] Then, according to the installation positions of different air radiators in the air radiator group, the second heat dissipation weight of different air radiators can be determined. The second heat dissipation weight is used to reflect the influence of different installation positions on the heat dissipation efficiency. Then, in the target heat dissipation scheme, the corresponding rotation speeds of different air radiators are determined, and through the rotation speed comparison weight form, the third heat dissipation weight corresponding to the target air radiator is determined. The third heat dissipation weight here is used to show the influence of the rotation speeds of other air radiators on the target air radiator, which can be pre-measured by the staff under experimental conditions and stored in the rotation speed comparison weight form. Finally, based on the first heat dissipation weight corresponding to different air radiator groups, the second heat dissipation weight corresponding to different air radiators, and the third heat dissipation weight, the heat dissipation coefficients corresponding to different air radiators can be determined.

[0050] In addition to the above confirmation method for reserving the adjustment time, it is also possible to determine the latest adjustment deadline corresponding to different temperature values to be adjusted without determining the reserved adjustment time, and use the latest adjustment deadline and the actual adjustment time as part of the reward function. For example, the reward function can be improved through the following formula:

[0051]

[0052] where t is the actual adjustment time, is the latest adjustment deadline. During the adjustment, we hope that the actual adjustment time is as small as possible, but in the case of a short time, we hope that the rotation speed is also relatively small, so as to achieve the effect of energy saving.

[0053] S403: Adjust the power supply of the power supply module according to the ideal rotation speed.

[0054] After determining the ideal rotation speeds of different air radiators at each time point, the power of different air radiators can be adjusted by controlling the power supply of the power supply module or the power generation power of the independent generator, so as to regulate the rotation speed of the air radiator, and then adjust the cooling speed of different regions of the corresponding component to be cooled.

[0055] By decoupling the air radiator from the engine and using another generator to supply power to the air radiator module separately, the influence of the rotation speed of the air radiator on the engine speed can be avoided. At the same time, by monitoring the temperature of the engine to control the rotation speed of the air radiator, the temperature of the engine can be better controlled, and the temperature of the engine can be regulated in zones to reduce the pressure of the engine, so that the air radiator can adapt to changing working conditions.
