[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The following describes a control method for an electric control device, a computer-readable storage medium, an electric control device, an electrical appliance, and an air conditioner according to embodiments of the present invention with reference to the accompanying drawings.

[0039] Figure 1 4 is a flow chart of a control method of an electronic control device according to an embodiment of the present invention.

[0040] See also Figure 2As shown, the electric control device 100 includes a plurality of first electric control modules 10, each of which includes a controllable switch. The electric control device 100 may be an intelligent power module.

[0041] Specifically, the first electric control module 10 may be a power factor correction unit, an inverter unit, etc., which is not limited here. The corresponding electric signal conversion function is realized by controlling the on and off of the controllable switches in the first electric control module 10. For example, when the plurality of first electric control modules 10 include an inverter unit, six controllable switches constitute three bridge arms, and the six controllable switches are controlled to be turned on sequentially to realize the conversion of direct current into three-phase alternating current output to drive the load to operate.

[0042] It should be noted that the plurality of first electric control modules 10 are electrically connected in the electric control device 100. Figure 2 It is only used to mark the modules in the electric control device 100, and does not represent the electrical connection. The connection can be made according to the actual situation. For example, when the multiple first electric control modules 10 include a power factor correction unit and an inverter unit, the input end of the inverter unit is connected to the output end of the power factor correction unit.

[0043] like Figure 1 As shown, the control method of the electronic control device according to the embodiment of the present invention may include:

[0044] S1, obtaining the temperature of each first electronic control module;

[0045] S2, when the temperature of any first electric control module is abnormal, adjusting the carrier frequency of at least one first electric control module among the plurality of first electric control modules, and controlling the controllable switch of the corresponding first electric control module according to the adjusted carrier frequency.

[0046] Specifically, continue with Figure 2Taking the electric control device 100 as an example, the temperature of each first electric control module 10 is acquired by the temperature acquisition module 20 arranged corresponding to the first electric control module 10. The temperature acquisition module 20 can be a thermistor temperature sensor, a thermocouple temperature sensor, a thermal resistor temperature sensor, etc., without specific limitation. The temperature acquisition module 20 can be arranged in the high temperature generating part of the corresponding first electric control module 10, and the temperature of the high temperature generating part is used as the current temperature of the corresponding first electric control module 10. For example, when the temperature acquisition module 20 adopts a thermistor temperature sensor, the temperature acquisition module 20 constructs a voltage divider circuit based on the thermistor, and arranges the thermistor in the high temperature generating part of the first electric control module 10. The resistance value of the thermistor is changed according to the temperature of the high temperature generating part. At this time, the voltage signal output by the temperature acquisition module 20 also changes with the change of the resistance value of the thermistor, thereby realizing the temperature detection of the first electric control module 10. Among them, the high temperature generating part of the first electronic control module 10 can be the layout position of high-power electronic components, or the position where the electronic components are arranged with a high density. The high temperature generating part can be determined according to actual conditions. The high-power electronic components can be thyristors, power transistors, power field effect transistors, etc.

[0047] The temperature of each first electric control module 10 is acquired respectively by a plurality of temperature acquisition modules 20, and the acquired temperature detection signal is sent to the controller 30. The controller 30 determines the temperature of each first electric control module 10 according to the received temperature detection signal, and determines whether the first electric control module 10 stores a temperature abnormality according to the temperatures of the plurality of first electric control modules 10. The temperature abnormality may be that the temperature difference between the two first electric control modules 10 is too large, or the temperature of the first electric control module 10 is too high or too low, etc. The preset temperature judgment condition may be determined based on a preset temperature abnormality type. For example, when the temperature abnormality type is that the temperature is too high, a temperature upper limit value may be preset, and the temperature of each first electric control module 10 is compared with the preset temperature upper limit value. When the temperature of the first electric control module 10 exceeds the first preset temperature upper limit value, it is considered that the temperature of the first electric control module 10 is too high. When the temperature abnormality type is that the temperature is too low, a temperature lower limit value may be preset, and the temperature of each first electric control module 10 is compared with the preset temperature lower limit value. When the temperature of the first electric control module 10 exceeds the first preset temperature upper limit value, it is considered that the temperature of the first electric control module 10 is too low.

[0048] The controller 30 can determine the first electric control module 10 with abnormal temperature according to the temperature of the first electric control module 10, so as to locate the first electric control module 10 with abnormal temperature, and further determine the first electric control module 10 that needs to adjust the carrier frequency according to the first electric control module 10 with abnormal temperature, and control the controllable switch of the corresponding first electric control module 10 with the adjusted carrier frequency. Among them, the electric control module adjustment rule can be set in advance, and the first electric control module 10 that needs to adjust the carrier frequency is determined according to the preset electric control module adjustment rule. For example, the carrier frequency of the first electric control module 10 with abnormal temperature is directly adjusted, or the corresponding target first electric control module is determined by looking up the table according to the first electric control module 10 with abnormal temperature, and the carrier frequency is adjusted for the corresponding target first electric control module. The adjustment strategy of the carrier frequency can be determined according to the type of temperature anomaly. For example, when the temperature of any first electric control module 10 is too high, the carrier frequency is reduced, thereby reducing the on-off frequency of the controllable switch of the corresponding first electric control module 10, so as to reduce the heat generated during the operation of the module, so as to achieve a cooling effect on the first electric control module 10 with too high temperature; when the temperature of any first electric control module 10 is too low, the carrier frequency is increased, thereby reducing the on-off frequency of the controllable switch of the corresponding first electric control module 10, so as to increase the heat generated during the operation of the module, so as to achieve a heating effect on the first electric control module 10 with too low temperature.

[0049] Therefore, this embodiment realizes the positioning of the first electric control module with abnormal temperature based on the temperature of each first electric control module and on the premise of whether the first electric control module has abnormal temperature, thereby determining the first electric control module that needs to perform carrier frequency adjustment according to the first electric control module with abnormal temperature, and further controlling the corresponding first electric control module with the adjusted carrier frequency, thereby adjusting the on-off frequency of the controllable switch of the first electric control module to achieve temperature adjustment of the electric control device. Based on the positioning of the first electric control module with abnormal temperature, this embodiment can achieve precise temperature control, and it is easy to achieve coordinated control of multiple first electric control modules, ensuring the reliable operation of the electric control device.

[0050] It should be noted that, in addition to implementing the above control method through a controller in the electronic control device, it can also be implemented based on an external control device, a host computer, etc. of the electronic control device, which is not limited here.

[0051] In one embodiment of the present invention, adjusting the carrier frequency of at least one first electronic control module among a plurality of first electronic control modules includes: adjusting the carrier frequency of at least one first electronic control module among any first electronic control module and a first adjacent electronic control module, wherein the first adjacent electronic control module is a first electronic control module adjacent to a position of any first electronic control module.

[0052] Specifically, Figure 3 For example, assuming that the plurality of first electric control modules include a first electric control module A, a first electric control module B and a first electric control module C, and the first electric control module A, the first electric control module B and the first electric control module C are sequentially arranged in the electric control device 100 from left to right along the horizontal direction. Assuming that the temperature of the first electric control module A is abnormal according to the acquired temperature of the first electric control module A, the temperature of the first electric control module B and the temperature of the first electric control module C, and based on the arrangement positions of the first electric control module A, the first electric control module B and the first electric control module C, it can be determined that the first electric control module B is the first adjacent electric control module of the first electric control module A. Then, after determining that the temperature of the first electric control module A is abnormal, the carrier frequency of the first electric control module A can be adjusted, and the carrier frequency of the first electric control module B can also be adjusted.

[0053] Assuming that the temperature of the first electric control module A is too high and the carrier frequency needs to be reduced, the on-off frequency of the controllable switch of the first electric control module A can be directly reduced by reducing the carrier frequency of the first electric control module A, so as to reduce the heat generated by the first electric control module A and reduce the temperature of the first electric control module A, so as to achieve a cooling effect on the first electric control module A; by reducing the carrier frequency of the first electric control module B, the on-off frequency of the controllable switch of the first electric control module B can be reduced to reduce the heat generated by the first electric control module B and reduce the temperature of the first electric control module B. Since the first electric control module B is adjacent to the first electric control module A, based on heat exchange, the adjacent first electric control module A can also be cooled to achieve a cooling effect on the first electric control module A.

[0054] It should be noted that the selection rule of the first adjacent electric control module can set the first electric control module directly adjacent to the first electric control module with temperature abnormality as the first adjacent module of the first electric control module with temperature abnormality; or a selection radius threshold can be preset, and after locating the first electric control module with temperature abnormality, the first electric control module with temperature abnormality is taken as the center of the circle, and all the first electric control modules within the preset selection radius threshold are regarded as the first adjacent electric control modules of the first electric control module with temperature abnormality. In other words, when it is determined that the first electric control module A has temperature abnormality, the carrier of the first electric control module C can be adjusted after the carrier frequency of the first electric control module A and the first electric control module B is adjusted, so as to achieve the temperature control effect of the first electric control module A.

[0055] In one embodiment of the present invention, the priority of adjusting the carrier frequency of any first electric control module is higher than the priority of adjusting the carrier frequency of a first adjacent electric control module.

[0056] Continue with Figure 3For example, if the temperature of the first electric control module A in the example is abnormal, and the first electric control module B is the first adjacent electric control module of the first electric control module A, since the temperature control effect achieved by directly adjusting the carrier frequency of the first electric control module A is better than the temperature control effect achieved by adjusting the carrier frequency of the second electric control module A, when it is determined that the temperature of the first electric control module A is abnormal, the carrier frequency of the first electric control module A is adjusted first. When the carrier frequency of the first electric control module A is adjusted to the preset upper frequency limit or the preset lower frequency limit, if the first electric control module A is still in the abnormal temperature state, the carrier frequency of the second electric control module B is further adjusted. In other words,

[0057] When a first electric control module has a temperature anomaly, the carrier frequency of the first electric control module is adjusted first, and the temperature of the first electric control module is adjusted directly. When the carrier frequency of the first electric control module is adjusted to a preset limit value, if the first electric control module still has a temperature anomaly, the first adjacent electric control module of the first electric control module is further adjusted, so as to achieve the purpose of adjusting the temperature of the first electric control module by adjusting the temperature of the first adjacent electric control module.

[0058] In one embodiment of the present invention, the control method of the electronic control device also includes: after adjusting the carrier frequency of at least one first electronic control module among the multiple first electronic control modules for multiple times, if the temperature of any first electronic control module is still abnormal, adjusting the load corresponding to any first electronic control module.

[0059] That is to say, continue with Figure 3 For example, if the temperature of the first electric control module A in the example is abnormal, and the first electric control module B is the first adjacent electric control module of the first electric control module A, if the temperature of the first electric control module A is still abnormal after adjusting the carrier frequencies of the first electric control module A and the second electric control module B, the load corresponding to the first electric control module A is adjusted. For example, when the temperature of the first electric control module A is too high, the load frequency corresponding to the first electric control module A is reduced to reduce the current flowing through the first electric control module A to achieve a cooling effect; when the temperature of the first electric control module A is too low, the load frequency corresponding to the first electric control module A is increased to increase the current flowing through the first electric control module A to achieve a heating effect.

[0060] In one embodiment of the present invention, the control method of the electronic control device also includes: when the temperature of any first electronic control module is greater than a first preset temperature t1, lowering the carrier frequency of at least one first electronic control module among the multiple first electronic control modules and the load corresponding to any first electronic control module; when the temperature of any first electronic control module is less than a second preset temperature t2, increasing the carrier frequency of at least one first electronic control module among the multiple first electronic control modules and the load corresponding to any first electronic control module, wherein the second preset temperature t2 is lower than the first preset temperature t1.

[0061] Continue with Figure 3 For example, assuming that when the temperature of the first electric control module A is abnormal, the temperature control effect of the first electric control module A is achieved by adjusting the first electric control module A and the load corresponding to the first electric control module A.

[0062] When the temperature of the first electric control module A is greater than the first preset temperature t1, it is considered that the temperature of the first electric control module A is too high, so the carrier frequency of the first electric control module A is reduced, and the load corresponding to the first electric control module A is lowered. On the one hand, by reducing the on-off frequency of the controllable switch of the first electric control module A, the heat generated by the first electric control module A is reduced, so as to achieve a cooling effect on the first electric control module A. On the other hand, by reducing the current flowing through the first electric control module A, the heat generated by the first electric control module A is reduced, so as to achieve a cooling effect on the first electric control module A.

[0063] When the temperature of the first electric control module A is lower than the second preset temperature t2, it is considered that the temperature of the first electric control module A is too low, and the carrier frequency of the first electric control module A is increased, and the load corresponding to the first electric control module A is increased. On the one hand, the heating value of the first electric control module A is increased by increasing the on-off frequency of the controllable switch of the first electric control module A, so as to achieve the heating effect of the first electric control module A. On the other hand, the heating value of the first electric control module A is increased by increasing the current flowing through the first electric control module A, so as to achieve the heating effect of the first electric control module A.

[0064] In one embodiment of the present invention, the electronic control device also includes at least one second electronic control module, each second electronic control module does not include a controllable switch, and the control method of the electronic control device also includes: when the temperature of any second electronic control module is abnormal, adjusting the carrier frequency of the second adjacent electronic control module, wherein the second adjacent electronic control module is a first electronic control module adjacent to the position of any second electronic control module.

[0065] The second electric control module may be an AC-DC (Alternating Current-Direct Current) conversion unit or a DC-DC (Direct Current-Direct Current) conversion unit, wherein the DC-DC conversion unit may be a boost unit or a buck unit. No controllable switch is provided in the second electric control module. When the second electric control module has a temperature abnormality, since no controllable switch is provided in the second electric control module, the carrier frequency of the first electric control module adjacent to the second electric control module is adjusted. By adjusting the temperature of the adjacent first electric control module, the temperature control effect of the second electric control module with the temperature abnormality is achieved.

[0066] Specifically, refer to Figure 4As shown, the temperature of each second electric control module 40 is acquired by the temperature acquisition module 20 arranged corresponding to each second electric control module 40, and sent to the controller 30. When the controller 30 determines that the temperature of the second electric control module 40 is abnormal, the carrier frequency of the corresponding first electric control module 10 is adjusted. Figure 5 For example, assuming that the plurality of first electric control devices are respectively the first electric control module A, the first electric control module B, and the first electric control module C, the second electric control module 40, the first electric control module A, the first electric control module B, and the first electric control module C are arranged in sequence from left to right in the horizontal direction, and the first electric control module A is adjacent to the second electric control module 40, and is the second adjacent electric control module of the second electric control module 40. When it is determined according to the acquired temperature that the second electric control module 40 has a temperature abnormality, the carrier frequency of the first electric control module A is adjusted. For example, when the temperature of the second electric control module 40 is too high, the carrier frequency of the first electric control module A is lowered to reduce the on-off frequency of the controllable switch of the first electric control module A, reduce the heat generated by the first electric control module A during operation, and reduce the temperature of the first electric control module A. Based on heat exchange, the adjacent second electric control module 40 can also achieve a cooling effect.

[0067] In one embodiment of the present invention, the multiple first electronic control modules include a power factor correction module, a compressor drive module for driving a compressor, and a fan drive module for driving a fan. The power factor correction module is electrically connected to the compressor drive module and the fan drive module, respectively, and the compressor drive module is located between the power factor correction module and the fan drive module.

[0068] The control method of the electric control device includes: when the temperature of the power factor correction module is abnormal, adjusting the carrier frequency of the power factor correction module, the carrier frequency of the compressor drive module, the compressor frequency and the fan frequency, wherein the priority of adjusting the carrier frequency is higher than the priority of adjusting the frequency, and the priority of adjusting the carrier frequency of the power factor correction module is the highest; when the temperature of the compressor drive module is abnormal, adjusting the carrier frequency of the compressor drive module, the carrier frequency of the power factor correction module, the carrier frequency of the fan drive module and the compressor frequency, wherein the priority of adjusting the carrier frequency is higher than the priority of adjusting the frequency, and the priority of adjusting the carrier frequency of the compressor drive module is the highest; when the temperature of the fan drive module is abnormal, adjusting the carrier frequency of the fan drive module, the carrier frequency of the compressor drive module and the fan frequency, wherein the priority of adjusting the carrier frequency is higher than the priority of adjusting the frequency, and the priority of adjusting the carrier frequency of the fan drive module is the highest.

[0069] Specifically, combined Figure 6 and Figure 7As shown, the second electric control module includes a rectifier module 41, and the plurality of first electric control modules include a power factor correction module 11, a compressor drive module 12, and a fan drive module 13, wherein the input end of the power factor correction module 11 is connected to the output end of the rectifier module 41, and the output end of the power factor correction module 11 is connected to the input end of the compressor drive module 12 and the input end of the fan drive module 13. The power factor correction module 11, the compressor drive module 12, and the fan drive module 13 are sequentially arranged in the electric control device 100 from left to right along the horizontal direction.

[0070] When the temperature of the power factor correction module 11 is abnormal, the carrier frequency of the power factor correction module 11 is first adjusted. If the power factor correction module 11 still has a temperature abnormality when the carrier frequency of the power factor correction module 11 is adjusted to the preset limit, the carrier frequency of the adjacent compressor drive module 12 is adjusted. If the power factor correction module 11 still has a temperature abnormality when the carrier frequency of the compressor drive module 12 is adjusted to the preset limit, since the compressor and the fan are both loads of the power factor correction module 11, the compressor frequency and the fan frequency are further adjusted.

[0071] When the temperature of the compressor driving module 12 is abnormal, the carrier frequency of the compressor driving module 12 is first adjusted. If the compressor driving module 12 still has abnormal temperature when the carrier frequency of the compressor driving module 12 is adjusted to the preset limit, because the power factor correction module 11 and the fan inverter module 13 are both adjacent to the compressor driving module 12, the carrier frequencies of the power factor correction module 11 and the fan inverter module 13 are further adjusted. If the compressor driving module 12 still has abnormal temperature when the carrier frequencies of the power factor correction module 11 and the fan inverter module 13 are both adjusted to the preset limit, the compressor frequency is further adjusted because the load of the compressor driving module 12 is the compressor.

[0072] When the temperature of the fan drive module 13 is abnormal, the carrier frequency of the fan drive module 13 is first adjusted. If the fan drive module 13 still has a temperature abnormality when the carrier frequency of the fan drive module 13 is adjusted to the preset limit, the carrier frequency of the adjacent compressor drive module 12 is adjusted. If the fan drive module 13 still has a temperature abnormality when the carrier frequency of the compressor drive module 12 is adjusted to the preset limit, the fan frequency is further adjusted because the load of the fan drive module 13 is a fan.

[0073] In one embodiment of the present invention, the control method of the electric control device further includes: when there is an abnormality in the temperature of the power factor correction module, the compressor drive module and the fan drive module, the carrier frequency of the power factor correction module, the carrier frequency of the compressor drive module, the carrier frequency of the fan drive module, the compressor frequency and the fan frequency are adjusted, wherein the priority of adjusting the carrier frequency is higher than the priority of adjusting the frequency; when there is an abnormality in the temperature of the power factor correction module and the compressor drive module, the carrier frequency of the power factor correction module, the carrier frequency of the compressor drive module, the carrier frequency of the fan drive module, the compressor frequency and the fan frequency are adjusted, wherein the priority of adjusting the carrier frequency is higher than the priority of adjusting the frequency, and when adjusting the carrier frequency, the priority of adjusting the carrier frequency of the fan drive module is the lowest; When there is an abnormality in the temperature of the power factor correction module and the fan drive module, the carrier frequency of the power factor correction module, the carrier frequency of the fan drive module, the carrier frequency of the compressor drive module, the compressor frequency and the fan frequency are adjusted, wherein the priority of adjusting the carrier frequency is greater than the priority of adjusting the frequency, and when adjusting the carrier frequency, the priority of adjusting the carrier frequency of the compressor drive module is the lowest; when there is an abnormality in the temperature of the compressor drive module and the fan drive module, the carrier frequency of the compressor drive module, the carrier frequency of the fan drive module, the carrier frequency of the power factor correction module, the compressor frequency and the fan frequency are adjusted, wherein the priority of adjusting the carrier frequency is greater than the priority of adjusting the frequency, and when adjusting the carrier frequency, the priority of adjusting the carrier frequency of the power factor correction module is the lowest.

[0074] Specifically, continue with Figure 7 For example, when the temperature of the power factor correction module 11, the compressor drive module 12 and the fan drive module 13 is abnormal, the carrier frequencies of the power factor correction module 11, the compressor drive module 12 and the fan drive module 13 are first adjusted. If the power factor correction module 11, the compressor drive module 12 and the fan drive module 13 still have temperature abnormalities when the carrier frequencies of the power factor correction module 11, the compressor drive module 12 and the fan drive module 13 are adjusted to the preset limit, the compressor frequency and the fan frequency are further adjusted. It can be understood that the subsequent load adjustment corresponds to the first electronic control module with temperature abnormality. For example, if the carrier frequencies of the power factor correction module 11, the compressor drive module 12 and the fan drive module 13 are adjusted to the preset limit, only the compressor drive module 12 has temperature abnormalities, then only the compressor frequency is adjusted.

[0075] When the temperature of the power factor correction module 11 and the compressor driving module 12 is abnormal, the carrier frequency of the power factor correction module 11 and the carrier frequency of the compressor driving module 12 are first adjusted. If the power factor correction module 11 and the compressor driving module 12 still have abnormal temperatures when the carrier frequency of the power factor correction module 11 and the carrier frequency of the compressor driving module 12 are adjusted to the preset limit, the carrier frequency of the adjacent fan driving module 13 is further adjusted. If the power factor correction module 11 and the compressor driving module 12 still have abnormal temperatures when the carrier frequency of the fan driving module 13 is adjusted to the preset limit, the compressor frequency and the fan frequency are further adjusted. Since the load of the compressor driving module 12 is a compressor, the compressor frequency can be adjusted in advance. When the compressor frequency is adjusted to the preset frequency limit, if there is still abnormal temperature, the fan frequency is further adjusted.

[0076] When the temperature of the power factor correction module 11 and the fan drive module 13 is abnormal, the carrier frequency of the power factor correction module 11 and the carrier frequency of the fan drive module 13 are first adjusted. If the power factor correction module 11 and the fan drive module 13 still have temperature abnormalities when the carrier frequencies of the power factor correction module 11 and the fan drive module 13 are adjusted to the preset limit, the carrier frequency of the adjacent compressor drive module 12 is further adjusted. If the power factor correction module 11 and the fan drive module 13 still have temperature abnormalities when the carrier frequency of the compressor drive module 12 is adjusted to the preset limit, the compressor frequency and the fan frequency are further adjusted. Since the load of the fan drive module 13 is a compressor, the fan frequency can be adjusted in advance. When the fan frequency is adjusted to the preset frequency limit, if there is still temperature abnormality, the compressor frequency is further adjusted.

[0077] When the temperature of the compressor drive module 12 and the fan drive module 13 is abnormal, the carrier frequency of the compressor drive module 12 and the carrier frequency of the fan drive module 13 are adjusted first. If the compressor drive module 12 and the fan drive module 13 still have temperature abnormalities when the carrier frequencies of the compressor drive module 12 and the fan drive module 13 are adjusted to the preset limit, the carrier frequency of the adjacent power factor correction module 11 is further adjusted. If the compressor drive module 12 and the fan drive module 13 still have temperature abnormalities when the carrier frequency of the power factor correction module 11 reaches the preset limit, the compressor frequency and the fan frequency are further adjusted, wherein the load adjustment is determined according to the first electronic control module with temperature abnormality. For example, if only the compressor drive module 12 has temperature abnormalities when the carrier frequency of the power factor correction module 11 reaches the preset limit, the compressor frequency can be adjusted first.
