Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of heat dissipation, and in particular to a projector control method, device, electronic device and computer-readable storage medium. Background Art

[0002] Some optical display devices in a projector may generate heat. To ensure the safe and reliable operation of the devices, a fan can be rotated to drive air flow for heat dissipation. As the temperature rises, if the fan air volume is blindly increased to ensure the heat dissipation effect, the noise generated by the fan will be relatively high. Therefore, related technologies can also achieve heat dissipation by reducing the current of the light source device.

[0003] However, reducing the current of the light source device will cause the brightness of the projector to decrease. Especially in the case where the user can customize the adjustment of the projector brightness, reducing the current of the light source device for heat dissipation and the user's customized brightness adjustment may conflict, resulting in frequent changes in the projector brightness, bringing a bad user experience, and even possible burnout.

[0063] The following will clearly and completely describe the technical solutions in the present application with reference to the drawings in the present application. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present invention.

[0064] In one embodiment, as Figure 1As shown, a projector control method is provided. Although the logical order is shown in the step schematic diagram, in some cases, the steps shown or described can be executed in an order different from that shown in the drawings. Specifically, the projector control method can be applied to a projector. Among them, the projector can include, but is not limited to, one or more of a Digital Light Processing (DLP) projector, a Liquid Crystal Display (LCD) projector, and a Liquid Crystal On Silicon (LCOS) projector.

[0065] The following will be described in detail respectively. It should be noted that the description order of the following embodiments does not limit the priority order of the embodiments.

[0066] According to Figure 1 the projector control method shown, the method at least includes steps S110 to S130, which are introduced in detail as follows:

[0067] In step S110, the temperature of the projector is collected.

[0068] The projector can be built-in with a temperature sensor, and the temperature sensor can collect the temperature of the projector.

[0069] In step S120, when the temperature of the projector is not higher than the first temperature threshold, heat dissipation is performed through a radiator.

[0070] The first temperature threshold is used to determine whether to perform heat dissipation through the light source current. The corresponding first temperature thresholds of different projectors can be different. The first temperature threshold can be obtained through experiments or tests. The first temperature threshold can be written into the projector configuration.

[0071] When it is monitored that the temperature of the projector is too high and heat dissipation treatment is required, it is determined whether the temperature of the projector is higher than the first temperature threshold. Among them, the temperature of the projector being too high can mean that the temperature of the projector is higher than the heat dissipation temperature threshold. Among them, the first upshift temperature can be obtained through experiments or tests.

[0072] When the temperature of the projector is higher than the heat dissipation temperature threshold and not higher than the first temperature threshold, heat dissipation can be performed through the radiator. Among them, performing heat dissipation through the radiator can include starting the radiator, or can include increasing the output power of the radiator. Among them, each time the output power of the radiator is increased, the output power of the radiator can be increased by one gear, and the output power of the radiator corresponding to each gear is preset. Correspondingly, each time the output power of the radiator is decreased, the output power of the radiator can be decreased by one gear. The change in the output power corresponding to each gear can be preset.

[0073] Optionally, the heat dissipation methods corresponding to the radiator may include, but are not limited to, any one or more of the following: air cooling, water cooling, and heat pipe cooling. For the sake of easy understanding, the following description takes the radiator as a fan for air cooling as an example. Among them, increasing the fan speed represents increasing the output power of the radiator.

[0074] In one embodiment, multiple heat dissipation temperature levels can be set between the heat dissipation temperature threshold and the first temperature threshold. When the temperature of the projector is higher than the heat dissipation temperature threshold and not higher than the first temperature threshold, the operating speed of the radiator is determined according to the heat dissipation temperature level at which the temperature of the projector is located.

[0075] For example, the heat dissipation temperature threshold is 35°C, the first temperature threshold is 65°C, and there are also two heat dissipation temperature levels of 45°C and 55°C respectively; when the temperature of the projector reaches 35°C, the fan can be turned on to the first speed for heat dissipation, when the temperature of the projector reaches 45°C, the fan speed can be adjusted to the second speed to improve the heat dissipation effect, and when the temperature of the projector reaches 55°C, the fan speed can be adjusted to the third speed to improve the heat dissipation effect.

[0076] In step S130, when the temperature of the projector is higher than the first temperature threshold, heat dissipation is performed by adjusting the light source current.

[0077] The light source current is the operating current of heat-generating devices such as optical display devices. Increasing the light source current will increase the brightness of the projector and also increase the heat generated by the heat-generating devices; conversely, decreasing the light source current will decrease the brightness of the projector and also reduce the heat generated by the heat-generating devices, thereby achieving heat dissipation.

[0078] When the temperature of the projector is higher than the first temperature threshold, heat dissipation treatment needs to be performed on the projector. At this time, the temperature of the projector is relatively high, and it may be difficult to achieve an ideal heat dissipation effect only relying on the radiator. Therefore, heat dissipation can also be achieved by decreasing the light source current.

[0079] In one embodiment, when the temperature of the projector is higher than the first temperature threshold and the light source current is decreased for heat dissipation, in order to achieve a better heat dissipation effect, the output power of the radiator can be further increased.

[0080] In another embodiment, when the temperature of the projector is higher than the first temperature threshold, in order to avoid the problem of excessive noise caused by further increasing the output power of the radiator, the output power of the radiator can be kept unchanged and only the light source current can be decreased.

[0081] Optionally, each time the light source current is increased, the light source current can be increased by one level, and the current value corresponding to each level of the light source current is preset. Correspondingly, each time the light source current is decreased, the light source current can be decreased by one level. The change in the light source current corresponding to each level can be preset.

[0082] With the technical solution of the embodiment of the present application, when the temperature of the projector is not higher than the first temperature threshold, heat dissipation is only carried out through the radiator, rather than by adjusting the light source current. Only when the temperature of the projector is higher than the first temperature threshold, it is possible to carry out heat dissipation by adjusting the light source current. In this way, the change of the light source current caused by heat dissipation can be reduced, thereby avoiding frequent changes in the brightness of the projector, improving the user experience, and avoiding serious situations such as burning out the machine.

[0083] Based on the above technical solution, as an embodiment, collecting the temperature of the projector may include collecting the temperature of the projector at regular intervals.

[0084] The period can be preset. The temperature of the projector can be collected at regular intervals to monitor the temperature of the projector, so as to take corresponding heat dissipation measures even if.

[0085] Collecting the temperature of the projector may also include: in response to an adjustment operation of the brightness of the projector, collecting the temperature of the projector.

[0086] It can be that the user adjusts the brightness of the projector. When receiving the adjustment operation of the brightness of the projector, the temperature of the projector can be collected, so as to judge whether to execute the adjustment operation of the brightness according to the temperature of the projector. If it is judged that the light source current should remain unchanged, the adjustment operation of the brightness is not responded to, so as to avoid the contradiction between the adjustment operation of the brightness and the adjustment operation of the light source current in the heat dissipation measure, resulting in frequent changes in the brightness of the projector.

[0087] Based on the above technical solution, as an embodiment, Figure 2 is a schematic diagram of the projector control logic provided by an embodiment of the present application. Refer to Figure 2 , when the temperature of the projector is higher than the first temperature threshold, heat dissipation by adjusting the light source current may include: when the temperature of the projector is higher than the first temperature threshold, determining whether the light source current is greater than the target current; when the light source current is greater than the target current, reducing the light source current for heat dissipation.

[0088] The target current is the maximum current that can satisfy the device under the entire operating environment temperature. The target current can be determined in advance according to experiments or tests. When the light source current is higher than the target current, heat dissipation can be carried out by reducing the light source current; when the light source current is not higher than the target current, the device is not restricted under the entire operating environment temperature, so there is no need to reduce the light source current for heat dissipation.

[0089] When the temperature of the projector is higher than the first temperature threshold, it can be judged whether the light source current is greater than the target current. When the light source current is greater than the target current, the light source current can be reduced for heat dissipation.

[0090] Optionally, when the temperature of the projector is higher than the first temperature threshold and the light source current is greater than the target current, the light source current can be lowered by one level, and the fan speed can be increased by one level to achieve sufficient heat dissipation through the light source current and the fan.

[0091] Optionally, when the temperature of the projector is higher than the first temperature threshold and the light source current is greater than the target current, the light source current can be lowered by one level while keeping the fan speed unchanged to avoid excessive noise caused by too high a fan speed, thus affecting the user experience.

[0092] Optionally, when the temperature of the projector is collected in response to the user's custom adjustment of the projector brightness, if the temperature of the projector is higher than the first temperature threshold and the light source current is greater than the target current, a high-temperature prompt can also be given to the user so that the user can know that the light source current / projector brightness cannot be increased further under the current conditions.

[0093] When the temperature of the projector is higher than the first temperature threshold but the light source current is not greater than the target current, the light source current cannot be lowered, so the light source current remains unchanged.

[0094] Optionally, when the temperature of the projector is higher than the first temperature threshold but the light source current is not greater than the target current, the light source current remains unchanged, and at the same time, the fan speed is increased by one level to increase heat dissipation.

[0095] Optionally, when the temperature of the projector is higher than the first temperature threshold but the light source current is not greater than the target current, both the light source current and the fan speed remain unchanged, and heat dissipation continues at the original fan speed.

[0096] By adopting the technical solution of the embodiment of the present application, based on the magnitude relationship between the light source current and the target current, it can be determined whether to lower the light source current for heat dissipation, thereby reducing the adjustment of the light source current, reducing the change in the projector brightness, and avoiding the bad user experience brought by the frequent change of the projector brightness.

[0097] On the basis of the above technical solution, as an embodiment, the first temperature threshold includes multiple first sub-temperature thresholds, and the target current includes multiple sub-target currents; the first sub-temperature thresholds and the sub-target currents are in one-to-one correspondence; when the light source current is greater than the target current, heat dissipation by lowering the light source current may include: when the temperature of the projector is higher than the first sub-temperature threshold and the light source current is greater than the sub-target current corresponding to the first sub-temperature threshold, heat dissipation is achieved by lowering the light source current.

[0098] In one embodiment, the first temperature threshold may include multiple different first sub-temperature thresholds. The first sub-temperature threshold is greater than the heat dissipation temperature threshold. The target current includes multiple sub-target currents. The first sub-temperature thresholds and the sub-target currents are in one-to-one correspondence.

[0099] When the temperature of the projector is higher than the first sub-temperature threshold and the light source current is greater than the sub-target current corresponding to the first sub-temperature threshold, lower the light source current by one level to achieve heat dissipation.

[0100] For example, multiple different first sub-temperature thresholds include 65°C and 70°C. The sub-target current corresponding to 65°C is 1A, the sub-target current corresponding to 70°C is 1.5A, and the light source current of one level is 0.2A. Then, when the temperature of the projector is 66°C and the light source current is 1.1A > 1A, the light source current can be lowered to 1.1A - 0.2A = 0.9A; when the temperature of the projector is 71°C and the light source current is 1.6A > 1.5A, the light source current can be lowered to 1.6A - 0.2A = 1.4A.

[0101] Adopting the technical solution of the embodiment of the present application, by distinguishing multiple first sub-temperature thresholds and multiple sub-target currents, the light source current can be regulated more precisely, thereby achieving a more accurate heat dissipation effect.

[0102] On the basis of the above technical solution, as an embodiment, referring to Figure 2 , the projector control method may further include: when the temperature of the projector is lower than the second temperature threshold, determining whether the light source current is greater than the target current; when the light source current is not greater than the target current, increasing the light source current and decreasing the heat dissipation capacity of the radiator.

[0103] The second temperature threshold is used to determine whether to cancel the heat dissipation measure. When the temperature of the projector is lower than the second temperature threshold, the heat dissipation measure can be cancelled (or considered to be cancelled); when the temperature of the projector is not lower than the second temperature threshold, the heat dissipation measure is not cancelled. Among them, cancelling the heat dissipation measure may refer to restoring the gear corresponding to the heat dissipation measure to the first gear, or directly cancelling the heat dissipation measure. For example, cancelling the heat dissipation measure corresponding to the fan may refer to lowering the gear of the fan by one level or turning off the fan.

[0104] The second temperature thresholds corresponding to different projectors may be different. The second temperature threshold can be obtained through experiments or tests. The second temperature threshold can be written into the projector configuration.

[0105] When the temperature of the projector is not lower than the second temperature threshold and not higher than the heat dissipation temperature threshold, maintain the original heat dissipation measure and do not adjust the radiator and the light source current.

[0106] When the temperature of the projector is lower than the second temperature threshold, it can be determined whether the light source current is greater than the target current. When the light source current is not greater than the target current, it proves that the heat dissipation measure of lowering the light source current was taken before. Therefore, this heat dissipation measure can be cancelled and the light source current can be increased.

[0107] Before dissipating heat through the light source current, the heat sink is preferentially used for heat dissipation. Therefore, when canceling the heat dissipation measure of reducing the light source current (increasing the light source current), the heat dissipation measure based on the heat sink can also be canceled, and the fan speed can be reduced. Herein, increasing the light source current may refer to increasing the light source current by one level, and reducing the fan speed may refer to reducing the fan speed by one level.

[0108] When the temperature of the projector is lower than the second temperature threshold and the light source current is greater than the target current, it proves that the heat dissipation measure of reducing the light source current has not been taken, or it means that the heat dissipation measure of reducing the light source current has been canceled. Therefore, the light source current is not adjusted.

[0109] By adopting the technical solution of the embodiment of the present application, when the temperature of the projector is lower than the second temperature threshold, the magnitude relationship between the light source current and the target current can be further judged, so as to determine whether the heat dissipation measure of reducing the light source current has been taken before, so as to determine whether the heat dissipation measure to be canceled currently includes the heat dissipation measure of reducing the light source current, and when it is determined that the heat dissipation measure is to be canceled, the light source current is increased to cancel the heat dissipation measure, so as to restore the projector to the brightness defined by the user.

[0110] On the basis of the above technical solution, as an embodiment, referring to Figure 2 , the projector control method may further include: when the light source current is greater than the target current, determining whether the temperature of the projector is lower than the third temperature threshold; when the temperature of the projector is lower than the third temperature threshold, reducing the heat dissipation capacity of the heat sink.

[0111] When the temperature of the projector is lower than the second temperature threshold and the light source current is greater than the target current, it proves that the heat dissipation measure of reducing the light source current has not been taken before, or it means that the heat dissipation measure of reducing the light source current has been canceled, but it is still necessary to judge whether to cancel the heat dissipation measure through the heat sink.

[0112] The third temperature threshold is used to determine whether to dissipate heat through the heat sink. The third temperature threshold is less than the second temperature threshold. The third temperature thresholds corresponding to different projectors may be different. The third temperature threshold can be obtained through experiments or tests. The third temperature threshold can be written into the projector configuration. When the temperature of the projector is lower than the third temperature threshold, it proves that one or more heat dissipation measures have been taken, and the temperature of the projector will be so low. Therefore, the corresponding heat dissipation measure can be canceled.

[0113] When the temperature of the projector is lower than the second temperature threshold and the light source current is greater than the target current, it is possible to judge whether the temperature of the projector is lower than the third temperature threshold.

[0114] When the light source current of the projector is greater than the target current, it proves that no heat dissipation measure of reducing the light source current has been taken, or it means that the heat dissipation measure of reducing the light source current has been cancelled. When the temperature of the projector is lower than the third temperature threshold and the light source current is greater than the target current, since no heat dissipation measure of reducing the light source current has been taken, it can be inferred that a heat dissipation measure using a radiator has been taken. Therefore, the heat dissipation measure corresponding to the radiator can be cancelled.

[0115] When the temperature of the projector is lower than the third temperature threshold and the light source current is greater than the target current, the heat dissipation capacity of the radiator can be reduced. For example, the fan speed can be increased.

[0116] By adopting the technical solution of the embodiment of the present application, when the light source current of the projector is greater than the target current, it can be determined whether heat dissipation is performed through a radiator by judging whether the temperature of the projector is lower than the third temperature threshold. Thus, when the temperature of the projector is lower than the third temperature threshold, the heat dissipation capacity of the radiator is reduced.

[0117] Based on the above technical solution, as an embodiment, referring to Figure 2 , the projector control method may further include: when the temperature of the projector is not lower than the third temperature threshold, keeping the light source current and the heat dissipation capacity of the radiator unchanged.

[0118] When the light source current of the projector is greater than the target current, it proves that no heat dissipation measure of reducing the light source current has been taken, or it means that the heat dissipation measure of reducing the light source current has been cancelled. When the temperature of the projector is lower than the second temperature threshold but not lower than the third temperature threshold, it proves that the current temperature is not too low. Therefore, the radiator and the light source current are kept unchanged.

[0119] By adopting the technical solution of the embodiment of the present application, when the light source current of the projector is greater than the target current and the temperature of the projector is lower than the second temperature threshold but not lower than the third temperature threshold, the radiator and the light source current can be kept unchanged, so as to maintain the original heat dissipation capacity.

[0120] Based on the above technical solution, as an embodiment, Figure 3 is a schematic diagram of the control logic corresponding to multiple second sub-temperature thresholds provided by an embodiment of the present application. Referring to Figure 3 , the second temperature threshold includes multiple second sub-temperature thresholds, and the target current includes multiple sub-target currents; the second sub-temperature thresholds and the sub-target currents are in one-to-one correspondence.

[0121] When the light source current is not greater than the target current, increasing the light source current and reducing the heat dissipation capacity of the radiator may include: when the temperature of the projector is lower than the second sub-temperature threshold and the light source current is not greater than the sub-target current corresponding to the second sub-temperature threshold, increasing the light source current and reducing the heat dissipation capacity of the radiator.

[0122] Figure 3 Each dashed box includes a second sub-temperature threshold and a sub-target current corresponding to the second sub-temperature threshold. According to actual requirements, there can be more dashed boxes (the second sub-temperature threshold and the sub-target current corresponding to the second sub-temperature threshold).

[0123] Figure 3 The multiple second sub-temperature thresholds in it include 30°C and 25°C. The sub-target current corresponding to 30°C is 1A, and the sub-target current corresponding to 25°C is 1.5A. When the temperature of the projector is lower than 30°C and the light source current is not greater than the sub-target current 1A corresponding to 30°C, the light source current can be increased and the heat dissipation capacity of the radiator can be decreased; when the temperature of the projector is lower than 30°C and the light source current is greater than the sub-target current 1A corresponding to 30°C, it can be further determined whether the temperature of the projector is lower than 25°C and whether the light source current is greater than the sub-target current 1.5A corresponding to 25°C; when the temperature of the projector is lower than 25°C and the light source current is not greater than the sub-target current 1.5A corresponding to 25°C, the light source current can be increased and the heat dissipation capacity of the radiator can be decreased.

[0124] By adopting the technical solution of the embodiment of the present application, multiple second sub-temperature thresholds and sub-target currents corresponding to the second sub-temperature thresholds are set, so that the light source current can be controlled more precisely, and thus more accurate heat dissipation control can be achieved.

[0132] A current heat dissipation unit, configured to dissipate heat by reducing the light source current when the light source current is greater than the target current.

[0133] In one embodiment, the first temperature threshold includes a plurality of first sub-temperature thresholds, and the target current includes a plurality of sub-target currents; the first sub-temperature thresholds and the sub-target currents are in one-to-one correspondence; the current heat dissipation module 403 includes:

[0135] In one embodiment, the device further includes:

[0136] A first determination module, configured to determine whether the light source current is greater than a target current when the temperature of the projector is lower than a second temperature threshold;

[0137] An adjustment module, configured to increase the light source current and reduce the heat dissipation capacity of the radiator when the light source current is not greater than the target current.

[0138] In one embodiment, the device further includes:

[0139] A second determination module, configured to determine whether the temperature of the projector is lower than a third temperature threshold when the light source current is greater than the target current;

[0144] The adjustment module includes:

[0149] By adopting the technical solution of the embodiment of the present application, when the temperature of the projector is not higher than the first temperature threshold, heat dissipation is only performed through the radiator, and the light source current is not adjusted for heat dissipation.
