DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort fall within the scope of protection of the present application.

[0018] With the rapid development of the field of electronic and electrical appliances, at present, screen modules have been widely applied to various electronic products, especially in the field of line controllers. With the popularization of intelligent screen modules, various screen failure problems have followed. The service life of a line controller mainly depends on a screen module and a controller. The higher the temperature, the worse the performance and service life of the screen module and the controller. Therefore, how to improve the service life of the line controller and handle the temperature rise of the line controller is an urgent problem to be solved.

[0019] To solve the above problems, the present application first proposes a temperature control method. Please refer to Figure 1 , Figure 1 FIG. 1 is a flow schematic diagram of a first embodiment of the temperature control method provided in the present application. In the present embodiment, the temperature control method is applied to a line controller, wherein the line controller comprises a screen module and a controller. As shown in Figure 1 , the temperature control method of the present embodiment can be realized through the following steps, specifically comprising steps S101 to S103: Step S101: Obtain the maximum temperature rise of the controller within a first preset time.

[0020] In the present embodiment, in order to reduce the influence of the temperature rise of the controller on the line controller, the present embodiment first needs to obtain the maximum temperature rise of the controller within a first preset time. Wherein, when obtaining the maximum temperature rise of the controller within the first preset time, a temperature sensor needs to be arranged on the controller, and a temperature sensor needs to be arranged on the upper and lower surfaces of the controller to obtain the temperature of the upper surface and the temperature of the lower surface. In the present embodiment, the controller can be a microcontroller such as a single-chip microcomputer.

[0021] In the present embodiment, within the first preset time, the temperature of the upper surface and the temperature of the lower surface of the controller can be obtained, the difference between the temperature of the upper surface and the temperature of the lower surface of the plurality of groups is calculated and compared, so as to obtain the maximum temperature rise within the first preset time. In the present embodiment, the first preset time can be set to 1 minute, and in other embodiments, it can also be set based on the actual situation, which is not limited here.

[0022] Step S102: in response to the maximum temperature rise being greater than the first temperature preset threshold, the running function corresponding to the maximum temperature rise is recorded into the function set, the controller is controlled to sequentially close the background applications from more to less in terms of unused time, and the brightness of the screen module is reduced to the lowest.

[0023] In the embodiment, the first temperature preset threshold is set as the highest temperature target value of the controller. When the maximum temperature rise obtained within the first preset time is greater than the first temperature preset threshold, it means that the temperature of the controller exceeds the highest temperature target value of the controller. At this time, the controller needs to be cooled, that is, the controller is controlled to sequentially close the background applications from more to less in terms of unused time. In order to ensure the heat dissipation efficiency, the brightness of the screen module of the controller also needs to be reduced to the lowest. In addition, in order to reduce the irreversible influence of temperature impact on the controller in the subsequent process and further ensure the stability of the controller, the running function of the controller corresponding to the maximum temperature rise needs to be recorded into the function set. When the running function in the function set is called subsequently, the controller automatically closes the background applications to cool down as soon as possible.

[0024] Step S103: in response to the maximum temperature rise being less than the second temperature preset threshold, the controller is controlled to sequentially restore the background applications in the reverse order of closing the background applications, and the brightness of the screen module is restored, wherein the second temperature preset threshold is less than the first temperature preset threshold.

[0025] In the embodiment, the second temperature preset threshold is set as the safe temperature value of the controller, that is, the second temperature preset threshold is set to be less than the first temperature preset threshold. As described above, after the controller sequentially closes the background applications from more to less in terms of unused time and reduces the brightness of the screen module to the lowest, the maximum temperature rise within the next first preset time can be continuously obtained. When the maximum temperature rise is less than the second temperature preset threshold, it means that the controller has been reduced to the safe temperature. At this time, the controller can be controlled to sequentially restore the background applications in the reverse order of closing the background applications, and the screen module can be controlled to restore to the previous brightness.

[0026] In the embodiment, the first temperature preset threshold and the second temperature preset threshold described above can be determined in combination with the product use scene and the temperature range of the specification of the controller.

[0027] Differently from the prior art, the temperature control method provided in the application comprises: acquiring a maximum temperature rise of the controller within a first preset time; in response to the maximum temperature rise being greater than a first temperature preset threshold, recording a running function corresponding to the maximum temperature rise into a function set, controlling the controller to sequentially close background applications from more to less in terms of unused time, and reducing the brightness of the screen module to the lowest; and in response to the maximum temperature rise being less than a second temperature preset threshold, controlling the controller to sequentially restore the background applications in reverse order of the closed background applications, and restoring the brightness of the screen module, wherein the second temperature preset threshold is less than the first temperature preset threshold. In this way, the temperature control method provided in the application can reduce the influence of high temperature on the performance of the controller, thereby prolonging the service life of the controller.

[0028] Optionally, referring to Figure 2 , Figure 2 is a flowchart of a second embodiment of the temperature control method provided in the application. As shown in Figure 2 , the temperature control method provided in the embodiment can be implemented through the following steps, specifically comprising steps S201 to S206: Step S201: acquiring a maximum temperature rise of the controller within a first preset time.

[0029] Step S201 is the same as step S101, and will not be described herein again.

[0030] Step S202: in response to the maximum temperature rise being greater than a first temperature preset threshold, recording a running function corresponding to the maximum temperature rise into a function set, controlling the controller to sequentially close background applications from more to less in terms of unused time, and reducing the brightness of the screen module to the lowest.

[0031] Step S202 is the same as step S102, and will not be described herein again.

[0032] Step S203: in response to the maximum temperature rise being less than a second temperature preset threshold, controlling the controller to sequentially restore the background applications in reverse order of the closed background applications, and restoring the brightness of the screen module, wherein the second temperature preset threshold is less than the first temperature preset threshold.

[0033] Step S203 is the same as step S103, and will not be described herein again.

[0034] Step S204: judging whether a running function in the function set is called in subsequent running of the controller.

[0035] As described above, in order to reduce the irreversible influence of temperature impact on the controller and further ensure the stability of the controller, the embodiment needs to record a running function corresponding to the maximum temperature rise of the controller into a function set, and judge whether the running function in the function set is called in subsequent running of the controller.

[0036] If the controller subsequently runs the running function in the function set, go to step S205; if the controller does not subsequently run the running function in the function set, work normally.

[0037] Step S205: automatically control the controller to sequentially close the background application from more to less in terms of the unused time.

[0038] In the subsequent running of the controller, if the controller needs to continue to run the running function in the function set, at the beginning of any running function in the function set, the controller can be automatically controlled to sequentially close the background application from more to less in terms of the unused time to prevent the temperature rise of the running function in the function set from causing an impact on the controller.

[0039] Step S206: in response to the end of the running function in the function set called by the controller, control the controller to sequentially restore the background application in the reverse order of closing the background application.

[0040] In the subsequent running of the controller, at the end of any running function in the function set, that is, in the subsequent running of the controller, none of the running functions in the function set is called, at this time, the controller can be controlled to sequentially restore the background application in the reverse order of closing the background application.

[0041] The embodiment can reduce the irreversible impact of the temperature shock of the running function with a large temperature rise on the controller, thereby further ensuring the stability of the drive-by-wire controller.

[0042] Optionally, based on the above embodiment, please refer to Figure 3 , Figure 3 is Figure 1 the flowchart of a specific embodiment of step S101. In the embodiment, the embodiment can implement step S101 through steps as shown in Figure 3 , and specifically includes steps S301 to S303: Step S301: within the first preset time, simultaneously collect the first temperature of the upper surface of the controller and the second temperature of the lower surface of the controller every fixed preset time.

[0043] In the embodiment, within the first preset time, the first temperature of the upper surface of the controller and the second temperature of the lower surface of the controller can be simultaneously collected every fixed preset time through the temperature sensor described above.

[0044] Exemplarily, as described above, the first preset time can be set as 1 minute. In the embodiment, the first preset time is taken as an example for introduction with 1 minute. The fixed preset time can be set as 5s. That is, in 1 minute, the first temperature of the upper surface of the controller and the second temperature of the lower surface of the controller can be collected simultaneously every 5s. At this time, 12 groups of the first temperature of the upper surface of the controller and the second temperature of the lower surface of the controller can be obtained.

[0045] Step S302: calculating the temperature difference between the first temperature and the second temperature collected each time.

[0046] As described above, after obtaining a plurality of groups of the first temperature of the upper surface of the controller and the second temperature of the lower surface of the controller, the temperature difference between the first temperature and the second temperature collected each time can be calculated respectively. The calculation of the temperature difference is shown in formula (1): (1) Wherein, T1 represents the first temperature of the upper surface of the controller, T2 represents the second temperature of the lower surface of the controller, and ΔT represents the temperature difference.

[0047] As described above, if the first preset time is taken as an example with 1 minute and the fixed preset time is taken as an example with 5s, 12 temperature differences can be obtained, which are , , .

[0048] Step S303: comparing all the temperature differences in the first preset time, and taking the maximum temperature difference as the maximum temperature rise.

[0049] In the embodiment, when all the temperature differences in the preset time are obtained, all the temperature differences can be compared, and the maximum temperature difference is taken as the maximum temperature rise in the first preset time.

[0050] As described above, if the first preset time is taken as an example with 1 minute and the fixed preset time is taken as an example with 5s, the maximum value of the temperature differences , , can be compared, and taken as the maximum temperature rise in the first preset time.

[0051] Optionally, based on the embodiment of Figure 3 , please refer to Figure 4 , Figure 4 is a flowchart of a temperature control method provided by the third embodiment of the application. As shown in Figure 4 , the temperature control method further includes steps S401 to S405: Step S401: Calculate the standard deviation of the temperature difference value within the first preset time, and determine whether the standard deviation is less than a preset threshold.

[0052] In the embodiment, based on the embodiment of Figure 3 In the process of obtaining the maximum temperature rise within the first preset time, the embodiment can also calculate the standard deviation of the temperature difference value within the first preset time, and determine whether the standard deviation is less than a preset threshold.

[0053] As described above, if the first preset time is 1 minute and the fixed preset time is 5 seconds, 12 temperature difference values can be obtained, respectively, , , .

[0054] At this time, based on the above 12 temperature difference values, the mean of the temperature difference value within the first preset time can be calculated, and the calculation formula of the mean is shown in formula (2): (2) Wherein, represents the mean of the temperature difference value within the first preset time, , , respectively represent the temperature difference value collected each time within the first preset time.

[0055] After obtaining the mean of the temperature difference value within the first preset time, the standard deviation of the temperature difference value can be calculated based on formula (3), and formula (3) is as follows: (3) Wherein, represents the standard deviation of the temperature difference value within the first preset time, represents the total number of collected temperatures within the first preset time, in the embodiment, i.e. 12; represents the temperature difference value obtained each time, represents the mean of the temperature difference value within the first preset time.

[0056] The standard deviation of the temperature difference value within the first preset time can be obtained by the above calculation, and then it can be determined whether the standard deviation is less than a preset threshold.

[0057] Step S402: If the standard deviation is less than the preset threshold, and the maximum temperature rise is less than the second temperature preset threshold and the temperature difference value is greater than the third temperature preset threshold, record the running function corresponding to the temperature difference value greater than the third temperature preset threshold to the function set.

[0058] When the calculated standard deviation is less than the preset threshold, it represents that the dispersion degree between the acquired temperature difference values collected within the first preset time is small. At this time, if the maximum temperature rise is less than the second temperature preset threshold described above, but the acquired temperature difference values described above 、 、…、 There is a case where the temperature difference value is greater than the third temperature threshold, which represents that the high-temperature duration of the controller is long. At this time, the running function corresponding to the case where the temperature difference value is greater than the third temperature preset threshold is recorded in the function set described above.

[0059] In the embodiment, the third temperature preset threshold can be set to 30℃, and in other embodiments, the third temperature preset threshold can also be set based on actual conditions, which is not limited here.

[0060] Step S403: Determine whether the running function in the function set is called in the subsequent running of the controller.

[0061] Similarly, in order to reduce the irreversible impact of temperature shock on the controller in the subsequent running and further ensure the stability of the controller, the running function corresponding to the case where the temperature difference value is greater than the third temperature preset threshold is also recorded in the function set described above, and it is determined whether the running function in the function set is called in the subsequent running of the controller.

[0062] If the running function in the function set is called in the subsequent running of the controller, go to step S404; if the running function in the function set is not called in the subsequent running of the controller, work normally.

[0063] Step S404: Automatically control the controller to sequentially close the background applications from more to less in terms of unused time.

[0064] Similarly, in the subsequent running of the controller, if the controller needs to continue to call the running function in the function set, when starting any running function in the function set, the controller can be automatically controlled to sequentially close the background applications from more to less in terms of unused time to prevent the temperature rise of the running function in the function set from impacting the controller.

[0065] Step S405: In response to the end of the running function in the function set called by the controller, control the controller to sequentially restore the background applications in the reverse order of closing the background applications.

[0066] Similarly, in the subsequent running of the controller, when any running function in the function set ends, i.e., when none of the running functions in the function set is called in the subsequent running of the controller, the controller can be controlled to sequentially restore the background applications in the reverse order of closing the background applications.

[0067] The embodiment can better prevent the controller from malfunctioning, thereby guaranteeing the performance of the controller, and further guaranteeing the performance and service life of the drive-by-wire controller.

[0068] Optionally, referring to Figure 5 , Figure 5 is a flowchart of a temperature control method provided in the fourth embodiment of the present application. In the embodiment, the temperature control method is applied to a screen module. As shown in Figure 5 , the temperature control method of the embodiment can be implemented through the following steps, specifically including steps S501 to S503. Step S501: Obtain the average temperature of the screen module at multiple positions within a second preset time.

[0069] As described above, the service life of the drive-by-wire controller depends not only on the controller but also on the screen module. Therefore, in order to improve the service life of the drive-by-wire controller, the screen module needs to be temperature-controlled in the embodiment.

[0070] In the process of using the drive-by-wire controller, the temperature gradient of the entire screen module is large, and the larger the screen module is, the more obvious the temperature difference is. If only one temperature collection point is set, it is too one-sided and cannot represent the heating condition of the entire screen module. Therefore, in the embodiment, at least five positions can be selected as temperature collection points when the screen temperature of the screen module is collected, and temperature sensors are arranged on the temperature collection points, so that the screen temperature of the entire screen module can be more comprehensively collected, which is helpful for accurate feedback and control of the temperature subsequently. The five collection points can be arranged at the periphery and the central region of the screen module.

[0071] In the embodiment, when the screen temperature of the screen module is collected, multiple sets of screen temperatures at multiple positions of the screen module within a second preset time are obtained, and the average temperature of the screen module at multiple positions within the second preset time is calculated.

[0072] Step S502: In response to the average temperature being greater than a third temperature preset threshold, the brightness of the screen module is reduced to the lowest.

[0073] In the embodiment, the third temperature preset threshold is set as the highest temperature target value of the screen module. When the average temperature obtained within the second preset time is greater than the third temperature preset threshold, it means that the temperature of the screen module exceeds the highest temperature target value of the screen module. At this time, the screen module needs to be cooled, that is, the brightness of the screen module is reduced to the lowest. In other embodiments, the brightness of the screen module can also be appropriately reduced based on the demand, which is not limited herein.

[0074] Step S503: In response to the average temperature being less than a fourth temperature preset threshold, the brightness of the screen module is restored, wherein the fourth temperature preset threshold is less than the third temperature preset threshold.

[0075] In the embodiment, the fourth temperature preset threshold is set as a safe temperature value of the screen module, i.e., the fourth temperature preset threshold is set to be less than the third temperature preset threshold. As described above, after the brightness of the screen module is reduced, the average temperature of the screen module in the next second preset time can be continuously acquired in a cycle, and when the average temperature is less than the fourth temperature preset threshold, it means that the screen module has been reduced to a safe temperature, at which time the screen module can be controlled to return to the previous brightness.

[0076] In the embodiment, the third temperature preset threshold and the fourth temperature preset threshold described above can be determined in combination with the product use scenario and the specification temperature range of the screen module.

[0077] Optionally, based on the above embodiment, please refer to Figure 6 , Figure 6 is Figure 5 a flowchart of a specific embodiment of step S501. In the embodiment, step S501 can be implemented by steps as shown in Figure 6 , and specifically includes steps S601 to S602: Step S601: screen temperatures at different positions of the screen module are cyclically collected in a second preset time according to a preset order, wherein each collection interval is fixedly preset time.

[0078] In the embodiment, in the second preset time, the screen temperatures at different positions of the screen module can be cyclically collected by the temperature sensor according to the preset order, and each collection interval is fixedly preset time.

[0079] For example, the second preset time is 1 minute, and the fixed preset time is 1 second. As described above, it is assumed that there are 5 temperature collection points on the screen module. At this time, the screen temperature of each temperature collection point can be cyclically collected every 1 second according to the preset order of the 5 temperature collection points. And in the collection process, the screen temperature of all temperature collection points needs to be collected before the cyclic collection is repeated. This design not only ensures that multiple positions of the screen module are fully collected, but also ensures that the temperature is collected every second, further ensuring the accuracy of the temperature collection of the screen module.

[0080] Step S602: calculate an average temperature based on the multiple screen temperatures in the second preset time.

[0081] After the multiple screen temperatures in the second preset time are acquired, the average temperature can be calculated based on the multiple screen temperatures.

[0082] Exemplarily, the second preset time is taken as 1 minute, the fixed preset time is taken as 1s, and it is assumed that 5 temperature collection points are arranged on the screen module as described above. At this time, when calculating the average temperature, the average temperature can be calculated once after collecting the screen temperatures of the 5 temperature collection points each time, and the average of the 12 average temperatures can be calculated when the second preset time ends, so as to obtain the average temperature of the screen module in the second preset time, wherein the specific calculation formula is shown in formula (5) and formula (6): (5) (6) wherein, represents the average temperature after collecting the temperatures of the 5 temperature collection points, respectively represent the screen temperatures collected by the 5 temperature collection points, represents the average temperature of the screen module in the second preset time, respectively represent the 12 average temperatures.

[0083] Optionally, based on the above embodiment, in the present embodiment, the step S502 can be implemented by the following steps, specifically including: In response to the fact that the plurality of average temperatures in the third preset time are all greater than the third temperature preset threshold, the brightness of the screen module is reduced to the lowest, wherein the third preset time is greater than the second preset time.

[0084] In the present embodiment, the third preset time is set to be greater than the second preset time. For example, the third preset time is taken as 3 minutes, and the second preset time is taken as 1 minute. At this time, the average temperatures of the 3 screen modules in the third preset time can be obtained, and when the average temperatures of the 3 screen modules in the third preset time are all greater than the third temperature preset threshold, it means that the temperature of the screen module exceeds the highest temperature target value of the screen module in the third preset time. At this time, the brightness of the screen module is reduced to the lowest.

[0085] If the plurality of average temperatures in the third preset time are all less than the third temperature preset threshold, the average temperature of the screen module can be obtained and the subsequent judgment can be performed based on the method described above.

[0086] Optionally, based on all the above embodiments, in the present application, the steps of turning off the background application, reducing the screen brightness or reducing the screen brightness to the lowest described above can also be distinguished according to whether there is a user operation. If there is no user operation at this time, the background program is closed or the screen brightness is reduced. If there is a user operation at this time, the screen module can pop up the "controller temperature is too high" or "screen temperature is too high prompt" and recommend the user operation guide, thereby further enhancing the user experience. However, the direct processing method described above is more conducive to reducing the influence of high temperature on the drive-by-wire controller.

[0087] Optionally, based on all the above embodiments, in this embodiment, please refer to Figure 7 , Figure 7 This is a flowchart illustrating the fifth embodiment of the temperature control method provided in this application. Figure 7 As shown, the temperature control method in this embodiment further includes steps S701 to S702: Step S701: Obtain the heat generated by each circuit module connected to the controller.

[0088] That is, in this embodiment, the heat generated by each circuit module connected to the controller can be obtained.

[0089] Step S702: When the controller controls the operation of a circuit module whose heat exceeds a preset heat threshold, other non-essential modules are stopped from operating.

[0091] For example, the temperature control method of this embodiment can also prevent temperature rise at the hardware level, specifically as follows: It mainly determines which circuit modules generate more heat by measuring the current of each circuit module connected to the controller, i.e., using Q=I... 2 The Rt formula is used to calculate and sort the circuit modules according to the amount of heat generated. When a circuit module that generates more heat is running, the operation of other non-essential modules can be automatically stopped. In this way, the amount of heat generated by the hardware circuit can be directly monitored and controlled.
