Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular, to a method, device, equipment and medium for regulating the power of a warm air heater. Background Art

[0002] With the rapid development of technology, the types of vehicles are gradually increasing. A warm air heater can be configured on a vehicle. When the warm air heater is started, it can heat the incoming air of the vehicle to increase the temperature inside the vehicle.

[0003] Currently, during the operation of the vehicle, the air conditioner temperature can be set by controlling the air conditioner knob. According to the air conditioner temperature, it can be determined whether the warm air heater configured in the vehicle is turned on. If the warm air heater is turned on, the warm air heater heats the incoming air of the air conditioner at a constant power until the temperature inside the vehicle reaches the target temperature, and then the warm air heater is turned off.

[0004] However, during the use of the warm air heater, it will frequently switch between the on and off states, reducing the service life of the warm air heater. At the same time, when it is in the on state, heating the incoming air of the air conditioner at a constant power causes the outlet air temperature to keep rising, and the outlet air temperature cannot be controlled, which easily leads to the aging and damage of vehicle components. At the same time, the warm air heater only heats at a constant power, consuming power and resulting in high energy consumption. Summary of the Invention

[0033] Embodiment 1

[0034] Figure 1 The figure is a flowchart of a method for adjusting the outlet air temperature of a warm air heater provided in Embodiment 1 of the present invention. The embodiment of the present invention is applicable to the situation of adjusting the outlet air temperature of a warm air heater. This method can be executed by a device for adjusting the outlet air temperature of a warm air heater, and the device for adjusting the outlet air temperature of a warm air heater can be implemented in the form of hardware and / or software.

[0035] See Figure 1 The method for adjusting the outlet air temperature of a warm air heater shown in the figure includes:

[0036] S101. Obtain the set temperature corresponding to the vehicle where the warm air heater is located, and obtain the real-time outlet air temperature generated when the warm air heater operates according to the current duty cycle.

[0037] Among them, the warm air heater is used to describe a device for heating the air entering the air conditioning system installed in the vehicle. The warm air heater can be a positive temperature coefficient thermistor heater. After the warm air heater heats the air received by the air conditioning system, the outlet air temperature of the air conditioning system can be changed, resulting in different real-time outlet air temperatures of the air blown out of the air conditioning system outlet at different moments during the heating process, so that the real-time outlet air temperature of the air blown out of the air conditioning system outlet reaches the set temperature expected by the user. The current duty cycle can be used to describe the duty cycle of the pulse signal adjustment of the warm air heater at the current time. The real-time outlet air temperature can be used to describe the outlet air temperature of the air conditioner after applying the current duty cycle to the warm air heater.

[0038] Specifically, the duty cycle refers to the ratio of the high-level time to the total cycle time within a pulse cycle. In the control of the air heater, Pulse Width Modulation (PWM) technology is usually adopted. The PWM signal controls the on and off of the switching device in the air heater circuit. When the PWM signal is at a high level, the switching device is turned on, and the power supply supplies power to the air heater, generating heat; when the PWM signal is at a low level, the switching device is turned off, and the air heater stops heating. By changing the duty cycle of the PWM signal, the power-on time of the air heater within a cycle can be controlled, thereby adjusting its average power. The larger the duty cycle, the higher the average voltage or current obtained by the air heater, the greater the power, the more heat is generated, and the higher the outlet air temperature of the air conditioner; conversely, the smaller the duty cycle, the lower the outlet air temperature. Obtain the set temperature corresponding to the vehicle where the air heater is located, and modulate the pulse signal of the air heater according to the current duty cycle to obtain the real-time outlet air temperature generated when the air heater operates according to the current duty cycle.

[0039] S102. Determine whether to adjust the current duty cycle according to the set temperature and the real-time outlet air temperature.

[0040] Specifically, the duty cycle adjustment condition can be preset, and the set temperature and the real-time outlet air temperature are matched with the preset duty cycle adjustment condition to obtain a matching result. The duty cycle adjustment condition can be the threshold of the temperature difference between the preset set temperature and the real-time outlet air temperature, or the preset adjustment duration for adjusting the air heater according to the current duty cycle. It can be determined whether the deviation between the real-time outlet air temperature and the set temperature is less than the preset deviation threshold. If the deviation between the real-time outlet air temperature and the set temperature is less than the preset deviation threshold, it indicates that the deviation between the current real-time outlet air temperature and the set temperature is large, and the current duty cycle needs to be adjusted; otherwise, the current duty cycle does not need to be adjusted. Or when the duration of modulating the pulse signal of the air heater according to the current duty cycle is less than the adjustment duration, it indicates that the current duty cycle of the air heater does not need to be changed, and the pulse signal of the air heater can still be adjusted according to the current duty cycle; when the duration of modulating the pulse signal of the air heater according to the current duty cycle is greater than or equal to the adjustment duration, it indicates that the current duty cycle is no longer suitable for the air heater, and the current duty cycle of the air heater needs to be changed to enable the vehicle interior temperature to quickly and accurately reach the set temperature of the air conditioner, and the pulse signal of the air heater is no longer adjusted according to the current duty cycle.

[0041] S103. When it is determined to adjust the current duty cycle, obtain the outlet air temperature difference in the adjacent time period associated with the real-time outlet air temperature.

[0042] Among them, adjacent time periods can be used to describe time periods adjacent to the time point corresponding to the real-time air outlet temperature. The air outlet temperature difference can be used to describe the difference in the air outlet temperatures corresponding to the endpoints of different time periods in adjacent time periods.

[0043] Specifically, when determining to adjust the current duty cycle, obtain the time point corresponding to the real-time air outlet temperature. Obtain a preset duration, which can be 1 second. According to the time point corresponding to the real-time air outlet temperature and the preset duration, at least one time period adjacent to or separated by a finite number of preset durations from the time point of the real-time air outlet temperature can be obtained, and the adjacent time periods associated with the real-time air outlet temperature are determined according to each time period. The duration of each time period in the adjacent time periods is the same as the preset duration.

[0044] S104. Determine the target duty cycle according to the air outlet temperature difference of the adjacent time periods.

[0045] Among them, the target duty cycle can be used to describe the duty cycle for preparing to adjust the pulse signal of the air heater.

[0046] Specifically, according to the air outlet temperature difference of the adjacent time periods, the temperature change trend can be obtained in real time, and then the target duty cycle can be determined to control the operating power of the air heater so that the temperature inside the vehicle is stabilized at the set temperature of the air conditioner. For example, if the air outlet temperature difference of the adjacent time periods is large, it means that the heating capacity of the current air heater does not match the actual demand, and the duty cycle of the air heater needs to be adjusted to make the real-time air outlet temperature closer to the set temperature to meet the actual needs of the user; when the air outlet temperature difference of the adjacent time periods is small, it indicates that the heating capacity of the current air heater is relatively matched with the actual demand, and the heating demand of the air heater is low, and the duty cycle of the device can be reduced, thereby reducing the operating power of the air heater and reducing energy consumption.

[0047] S105. Update the current duty cycle according to the target duty cycle.

[0048] Specifically, during the operation of the air heater, it will be affected by various factors, such as load changes, ambient temperature changes, or power supply voltage fluctuations. These factors may cause the real-time air outlet temperature of the air heater to deviate from the set temperature. By real-time monitoring the air outlet temperature difference of the adjacent time periods of the air heater, calculating the target duty cycle according to the air outlet temperature difference, and updating the current duty cycle by calculating the target duty cycle, with the goal of making the temperature difference between the real-time air outlet temperature and the set temperature smaller, the current duty cycle can be updated, enabling the air heater to adapt to these changes in a timely manner and maintain a stable output. In PWM control, the higher the duty cycle, the higher the average voltage or power of the output signal. By updating the current duty cycle to the target duty cycle, the real-time air outlet temperature of the air heater can accurately reach the set temperature, achieving precise control.

[0049] In the technical solution of the embodiment of the present invention, the set temperature corresponding to the vehicle where the air heater is located is obtained, and the real-time air outlet temperature generated when the air heater operates according to the current duty ratio is obtained; whether to adjust the current duty ratio is judged according to the set temperature and the real-time air outlet temperature; when it is determined to adjust the current duty ratio, the air outlet temperature difference in the adjacent time period associated with the real-time air outlet temperature is obtained; the target duty ratio is determined according to the air outlet temperature difference in the adjacent time period; the current duty ratio is updated according to the target duty ratio, and the target duty ratio can be determined through the air outlet temperature difference in the adjacent time period associated with the real-time air outlet temperature, so that the air heater adjusts the current duty ratio according to the target duty ratio, thereby adjusting the power of the air heater to adjust the air outlet temperature, and realizing fine control of the air outlet temperature, improving the accuracy of adjusting the air outlet temperature of the air heater.

[0050] Embodiment 2

[0051] Figure 2 It is a flowchart of a method for adjusting the air outlet temperature of an air heater provided in Embodiment 2 of the present invention. On the basis of the above embodiment, the present invention optimizes and improves the operation of adjusting the air outlet temperature of the air heater.

[0052] Further, "determining the target duty ratio according to the air outlet temperature difference in the adjacent time period" is refined to "the adjacent time period includes: the first time period, the second time period and the third time period; obtaining the first air outlet temperature difference in the first time period, the second air outlet temperature difference in the second time period and the third air outlet temperature difference in the third time period; the first time period is before the second time period, and the second time period is before the third time period; calculating the target duty ratio according to the first air outlet temperature difference in the first time period, the second air outlet temperature difference in the second time period and the third air outlet temperature difference in the third time period", so as to improve the operation of adjusting the air outlet temperature of the air heater.

[0053] It should be noted that for the parts not detailed in the embodiments of the present invention, reference may be made to the descriptions of other embodiments.

[0054] See Figure 2 The method for adjusting the air outlet temperature of the air heater shown includes:

[0055] S201. Obtain the set temperature corresponding to the vehicle where the air heater is located, and obtain the real-time air outlet temperature generated when the air heater operates according to the current duty ratio.

[0056] S202. Judge whether to adjust the current duty ratio according to the set temperature and the real-time air outlet temperature.

[0057] S203. When it is determined to adjust the current duty ratio, obtain the air outlet temperature difference in the adjacent time period associated with the real-time air outlet temperature.

[0058] S204. The adjacent time periods include: a first time period, a second time period, and a third time period. Obtain the first air outlet temperature difference in the first time period, the second air outlet temperature difference in the second time period, and the third air outlet temperature difference in the third time period. The first time period is before the second time period, and the second time period is before the third time period.

[0059] Specifically, obtain the time point corresponding to the real-time air outlet temperature and a preset duration. Subtract the preset duration from the real-time time point corresponding to the real-time air outlet temperature to obtain a third time point. Determine the third time period based on the real-time time point and the third time point. Subtract the preset duration from the third time point to obtain a second time point. Determine the second time period based on the third time point and the second time point. Subtract the preset duration from the second time point to obtain a first time point. Determine the first time period based on the second time point and the first time point. Among them, the first time period is before the second time period, and the second time period is before the third time period.

[0060] S205. Calculate a target duty ratio based on the first air outlet temperature difference in the first time period, the second air outlet temperature difference in the second time period, and the third air outlet temperature difference in the third time period.

[0061] Specifically, obtain a set of items to be processed corresponding to the target duty ratio. The set of items to be processed includes: a first processing item, a second processing item, and a third processing item. The first processing item is the difference between the product of a first coefficient and the air outlet temperature difference corresponding to the third time period and the air outlet temperature difference corresponding to the second time period. The second processing item is the product of a second coefficient and the air outlet temperature difference corresponding to the third time period. The third processing item is the product of the sum of the difference between the air outlet temperature difference corresponding to the third time period and twice the air outlet temperature difference corresponding to the second time period and the air outlet temperature difference corresponding to the first time period and a third coefficient. Among them, the first coefficient, the second coefficient, and the third coefficient are set according to experimental data.

[0062] S206. Update the current duty ratio according to the target duty ratio.

[0063] In the embodiment of the present invention, by obtaining the first air outlet temperature difference in the first time period, the second air outlet temperature difference in the second time period, and the third air outlet temperature difference in the third time period; the first time period is before the second time period, and the second time period is before the third time period; calculating the target duty ratio according to the first air outlet temperature difference in the first time period, the second air outlet temperature difference in the second time period, and the third air outlet temperature difference in the third time period, determining the deviation degree between the real-time air outlet temperature and the set temperature through the temperature change trend, and calculating the target duty ratio, the calculation method of the target duty ratio is refined, and the accuracy of calculating the target duty ratio is improved.

[0064] Optionally, obtaining the air outlet temperature difference in adjacent time periods associated with the real-time air outlet temperature includes: obtaining two time period endpoints corresponding to the first time period, the second time period, and the third time period in the adjacent time periods; and determining the air outlet temperature difference in the adjacent time periods associated with the real-time air outlet temperature according to the air outlet temperatures at the time points generated by each time period endpoint in the adjacent time periods.

[0065] Among them, the time period endpoint can be the start time point or the end time point of a time period. The air outlet temperature at the time point can be used to describe the air outlet temperature of the air conditioner at the time period endpoint.

[0066] Specifically, one time period corresponds to one start time point and one end time point. The third time point corresponding to the first time period is the start time point of the first time period, and the second time point corresponding to the first time period is the end time point of the first time period. The second time point corresponding to the second time period is the start time point of the second time period, and the first time point corresponding to the second time period is the end time point of the second time period. The second time point corresponding to the third time period is the start time point of the third time period, and the real-time time point corresponding to the real-time air outlet temperature of the third time period is the end time point of the third time period. Obtain the air outlet temperatures at the first time point, the second time point, the third time point, and the real-time time point. The air outlet temperature difference of the first time period is the difference between the air outlet temperature at the second time point and the air outlet temperature at the second time point. The air outlet temperature difference of the second time period is the difference between the air outlet temperature at the second time point and the air outlet temperature at the first time point. The air outlet temperature difference of the third time period is the difference between the air outlet temperature at the first time point and the air outlet temperature at the real-time time point.

[0067] By obtaining two time period endpoints corresponding to the first time period, the second time period, and the third time period in the adjacent time periods; and determining the air outlet temperature difference in the adjacent time periods associated with the real-time air outlet temperature according to the air outlet temperatures at the time points generated by each time period endpoint in the adjacent time periods, by calculating the air outlet temperature difference between the time period endpoints corresponding to each time period, the amount of data of the temperatures corresponding to each time point in the time periods to be processed can be reduced, and the data processing efficiency can be improved.

[0068] Optionally, the initial duty ratio is obtained according to the following steps: obtaining the vehicle circulation mode, the air volume gear, and the temperature information, where the temperature information includes: the indoor temperature and the outdoor temperature; screening the inlet air temperature from the temperature information according to the vehicle circulation mode; and determining the current duty ratio of the air heater according to the inlet air temperature and the air volume gear.

[0069] Among them, the vehicle circulation mode can be used to describe the air intake mode of the air conditioner on the vehicle. The air volume gear can be used to describe the air volume level of the air outlet of the air conditioner on the vehicle. The temperature information can be used to describe the set of temperatures collected by the temperature sensors on the vehicle. The indoor temperature can be used to describe the internal temperature of the vehicle collected by the temperature sensor. The outdoor temperature can be used to describe the external temperature of the vehicle collected by the temperature sensor. The intake air temperature can be used to describe the temperature of the air to enter the interior of the air conditioner.

[0070] Specifically, the vehicle circulation mode mainly refers to the internal circulation and external circulation modes of the vehicle air conditioner. There is a controller, which is connected to the indoor temperature sensor through a wire harness and is used to receive the indoor temperature of the cab. The controller can also receive the outdoor temperature sent by the outdoor temperature sensor through a Controller Area Network (CAN) or Local Interconnect Network (LIN) signal. Obtain the vehicle circulation mode. When the vehicle circulation mode is the internal circulation, the intake air temperature is determined to be the indoor temperature. When the vehicle circulation mode is the external circulation, the intake air temperature is determined to be the outdoor temperature. According to the intake air temperature and the air volume gear, determine the current duty ratio of the air heater.

[0071] By obtaining the vehicle circulation mode, air volume gear and temperature information, the temperature information includes: indoor temperature and outdoor temperature; according to the vehicle circulation mode, screen out the intake air temperature from the temperature information; according to the intake air temperature and the air volume gear, determine the current duty ratio of the air heater. For different intake air temperatures, different current duty ratio determination methods are executed, which refines the current duty ratio determination method and improves the accuracy of the current duty ratio calculation.

[0072] Optionally, obtaining the real-time outlet air temperature generated by the air heater operating at the current duty ratio includes: obtaining at least one temperature group, where the temperature group includes a set temperature, an outdoor sensor temperature, and an outlet air temperature calculation relationship; the outlet air temperature calculation relationship is used to calculate the real-time outlet air temperature according to the set temperature, and the outlet air temperature calculation relationship corresponds to the set temperature and the outdoor sensor temperature; obtain the set temperature and the real-time outdoor temperature; screen in each temperature group according to the set temperature and the real-time outdoor temperature to determine the target group; calculate the real-time outlet air temperature according to the set temperature and the outdoor sensor temperature and the outlet air temperature calculation relationship in the target group.

[0073] Among them, the outlet air temperature calculation relationship can be used to describe the calculation method for calculating the outlet air temperature. The temperature group can be used to describe the set of the set temperature, the outdoor sensor temperature, and the outlet air temperature calculation relationship. The target group can be used to describe the temperature group to which the set temperature and the real-time outlet air temperature belong.

[0074] Specifically, at least one temperature group is obtained. The temperature group includes a set temperature, an outdoor sensor temperature, and a calculation relationship for the outlet air temperature. The calculation relationship for the outlet air temperature can be obtained through experiments or preset according to user requirements. The calculation relationship for the outlet air temperature is used to calculate the real-time outlet air temperature based on the set temperature, and the calculation relationship for the outlet air temperature corresponds to the set temperature and the outdoor sensor temperature; the set temperature and the real-time outdoor temperature are obtained; screening is performed among the temperature groups according to the set temperature and the real-time outdoor temperature to determine the target group. The screening methods include, but are not limited to: sequential search algorithm, block search algorithm, hash search algorithm, and tree table search algorithm. The embodiments of the present invention do not limit this; the real-time outlet air temperature is calculated according to the set temperature and the outdoor sensor temperature and the calculation relationship for the outlet air temperature in the target group. By way of example, the real-time outlet air temperature can be represented by Ta, and the set temperature benefit can be represented by Ts. When the outdoor sensor temperature is less than -15°C and the temperature range of the set temperature is [18°C, 32°C], Ta = K1Ts 2 + K2Ts – K3, where K1, K2, and K3 are preset coefficients that can be obtained through experiments or preset; when the temperature range of the outdoor sensor temperature is [-15°C, -10°C] and the temperature range of the set temperature is [18°C, 31°C], Ta = K1Ts 2 + K2Ts – K3 - 2; when the temperature range of the outdoor sensor temperature is [-10°C, -5°C] and the temperature range of the set temperature is [18°C, 31°C], Ta = K1Ts 2 + K2Ts – K3 - 4.

[0075] By obtaining at least one temperature group, the temperature group includes a set temperature, an outdoor sensor temperature, and a calculation relationship for the outlet air temperature; the calculation relationship for the outlet air temperature is used to calculate the real-time outlet air temperature based on the set temperature, and the calculation relationship for the outlet air temperature corresponds to the set temperature and the outdoor sensor temperature; the set temperature and the real-time outdoor temperature are obtained; screening is performed among the temperature groups according to the set temperature and the real-time outdoor temperature to determine the target group; the real-time outlet air temperature is calculated according to the set temperature and the outdoor sensor temperature and the calculation relationship for the outlet air temperature in the target group. The calculation relationship for the outlet air temperature can be obtained according to the set temperature and the temperature of the outdoor sensor, and the real-time outlet air temperature is determined according to the calculation relationship for the outlet air temperature, and the numerical value of the accurate real-time outlet air temperature can be obtained, improving the accuracy of the outlet air temperature adjustment of the air heater.

[0076] Optionally, the calculation relationship for the outlet air temperature includes: a standard calculation relationship and / or adjustment data.

[0077] Among them, the standard calculation relationship can be used to describe the calculation method for calculating the real-time outlet air temperature through the set temperature and the outdoor sensor temperature. The adjustment data can be used to describe the data for adjusting the calculation method of the standard calculation relationship.

[0078] Specifically, due to reasons such as the excessively high temperature of the outdoor sensor or the aging of the outdoor sensor device, the temperature detected by the outdoor sensor may not be accurate enough. Therefore, the real-time outlet air temperature determined according to the set temperature, the outdoor sensor temperature, and the calculation relationship of the outlet air temperature is not accurate enough, and the temperature difference from the actual outlet air temperature exceeds the allowable deviation data range. Then, for different outdoor sensor temperature intervals, adjustment data corresponding to different outdoor temperature intervals can be set, and the real-time outlet air temperature calculated by the standard calculation relationship can be adjusted according to the adjustment data to obtain an accurate real-time outlet air temperature.

[0079] The calculation relationship of the outlet air temperature includes: the standard calculation relationship and / or the adjustment data, and the real-time outlet air temperature calculated by the standard calculation relationship can be adjusted to make the calculated real-time outlet air temperature closer to the value of the actual outlet air temperature, improving the accuracy of the outlet air temperature adjustment.

[0080] Optionally, after obtaining the real-time outlet air temperature generated when the air heater operates according to the current duty cycle, it further includes: obtaining a first temperature threshold and a second temperature threshold, where the first temperature threshold is greater than the second temperature threshold; if the real-time outlet air temperature is greater than the first temperature threshold, the air heater stops operating; if the real-time outlet air temperature is less than the second temperature threshold, a preset time is obtained, and the air heater operates at the current duty cycle for the preset time.

[0081] Specifically, a first temperature threshold and a second temperature threshold are obtained, where the first temperature threshold is greater than the second temperature threshold; if the real-time outlet air temperature is greater than the first temperature threshold, it indicates that the real-time outlet air temperature at the current time is too high, which may cause equipment aging or component damage, and then the controller is used to control the air heater to stop operating; if the real-time outlet air temperature is less than the second temperature threshold, it indicates that the current real-time outlet air temperature is too low. Then, instead of adjusting the current duty cycle according to the real-time outlet air temperature and the set temperature, a preset time is obtained, and the air heater operates at the current duty cycle for the preset time. After the air heater operates at the current duty cycle for the preset time, the current duty cycle is adjusted according to the real-time outlet air temperature and the set temperature.
