[0082] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0083] Before explaining the embodiments of the present application, the application scenarios of the present application will be described first. The application scenario of the present application is specifically based on controlling the rotation speed of a heat dissipation unit (such as a fan) in a projector, and then regulating the internal temperature of the projector. Figure 1 Schematic structural diagram of a projector control system provided by an embodiment of the present application, as Figure 1As shown in the figure, the projector control system may include a main controller 101, a light-emitting unit 102, a heat dissipation unit 103, an internal temperature sensor 104, an ambient temperature sensor 105, and a brightness sensor 106. Among them, the light-emitting unit 102, the heat dissipation unit 103, the internal temperature sensor 104, the ambient temperature sensor 105, and the brightness sensor 106 may be respectively connected to the main controller 101. The main controller 101, the light-emitting unit 102, the heat dissipation unit 103, and the internal temperature sensor 104 may all be disposed in the projector 100. The ambient temperature sensor 105 and the brightness sensor 106 may both be disposed in the environment where the projector 100 is located. Specifically, the ambient temperature sensor 105 and the brightness sensor 106 may both be disposed on the outer surface of the projector 100. The main controller 101 may determine the operating parameters of the heat dissipation unit 103 according to the brightness level of the light-emitting unit 102, the internal temperature information of the projector 100 detected by the internal temperature sensor 104, the ambient temperature information of the projector 100 detected by the ambient temperature sensor 105, and the ambient brightness information detected by the brightness sensor 106. The operating parameters may specifically be rotation speed parameters. The main controller 101 controls the heat dissipation unit 103 to dissipate heat based on the operating parameters, so that the temperature in the projector 100 is maintained within a reasonable range.

[0084] It should be noted that the present application can split and combine the above-mentioned content according to the following embodiments, and can control the heat dissipation unit to dissipate heat in various ways.

[0085] The following can explain the projector control method mentioned in the present application through the embodiments of the present application. Figure 2 It is a schematic flowchart of a projector control method provided by an embodiment of the present application. As Figure 2 shown, the method includes:

[0086] S201. Determine the brightness level of the light-emitting unit in the projector.

[0087] Among them, the projector may include at least one light-emitting unit. The light-emitting unit may specifically be composed of light-emitting diodes (LEDs). The main controller may send a current control instruction corresponding to the required brightness level to each light-emitting unit according to the required brightness level sent by the host computer. Each light-emitting diode generates a brightness level corresponding to the required brightness level based on the current control instruction. Optionally, the main controller may directly determine the brightness level of the light-emitting unit according to the required brightness level sent by the host computer, or the main controller may determine the brightness level of the light-emitting unit according to the current information of the light-emitting unit, or the brightness level of the light-emitting unit corresponding to the temperature information in the projector. The present application does not limit it.

[0088] S202. Determine the target operating parameters of the heat dissipation unit in the projector according to the brightness level of the light-emitting unit.

[0089] Among them, the correspondence between the brightness level of the light-emitting unit and the operating parameters of the heat dissipation unit can be stored in advance in the memory associated with the main controller. After the main controller determines the brightness level of the light-emitting unit, the target operating parameters of the heat dissipation unit can be directly obtained according to this correspondence. Further, the target operating parameters of the heat dissipation unit can be determined according to the correspondence between the brightness level of the light-emitting unit in the projector, the number information of the light-emitting units in the projector, and the operating parameters of the heat dissipation unit. Among them, the heat dissipation unit is specifically a fan, and the main controller can determine the rotation speed information of the fan according to the brightness level.

[0090] It can be understood that the correspondence between the brightness level of the light-emitting unit and the target operating parameters of the heat dissipation unit can be described as follows: the higher the brightness level of the light-emitting unit, the greater the target operating parameters required for the heat dissipation unit to perform heat dissipation. Among them, the higher the brightness level indicates that the brightness state displayed by the light-emitting unit is brighter. For example, when the brightness level of the light-emitting unit is higher, the fan, which is the specific form of the heat dissipation unit, needs to operate at a higher rotation speed (target operating parameter) to reduce the internal temperature of the projector.

[0091] S203. Control the heat dissipation unit to dissipate heat according to the target operating parameters.

[0092] Among them, after the main controller determines the target operating parameters corresponding to the heat dissipation unit, a control instruction can be generated based on the target operating parameters. The main controller sends the control instruction to the heat dissipation unit to control the heat dissipation unit to dissipate heat. The heat dissipation unit is specifically a fan, that is, the main controller makes the fan in the projector work at the target rotation speed (target operating parameter) to keep the temperature in the projector within a reasonable range.

[0093] In summary, for the projector control method provided by the embodiments of the present application, the main controller can directly use the correspondence between the brightness level of the light-emitting unit and the operating parameters of the heat dissipation unit to determine the target operating parameters of the heat dissipation unit, and then use the target operating parameters of the heat dissipation unit corresponding to the brightness level of the light-emitting unit to control the heat dissipation unit to dissipate heat. That is to say, the present application directly uses the brightness level of the light-emitting unit, which has the most direct relationship with the temperature information in the projector, to determine the target operating parameters of the heat dissipation unit, and controls the heat dissipation unit in the projector to perform heat dissipation processing based on the target operating parameters. This can improve the accuracy of the target operating parameters of the heat dissipation unit, and further avoid affecting the heat dissipation effect of the projector.

[0094] Optionally, determining the target operating parameter of the heat dissipation unit in the projector according to the brightness level of the light-emitting unit includes: determining the target operating parameter of the heat dissipation unit in the projector according to the temperature information associated with the projector and the brightness level of the light-emitting unit, where the temperature information includes: the internal temperature in the projector and / or the ambient temperature in the environment where the projector is located.

[0095] In an implementable embodiment, the main controller may receive the internal temperature in the projector and the brightness level of the light-emitting unit. According to the correspondence relationship stored in advance in the memory associated with the main controller between the internal temperature in the projector, the brightness level of the light-emitting unit, and the operating parameter of the heat dissipation unit, the main controller may determine the target operating parameter of the heat dissipation unit in the projector. Specifically, the memory stores the correspondence relationship between the brightness level of the light-emitting unit and the temperature threshold. The main controller may determine the target operating parameter of the heat dissipation unit in the projector according to the comparison result between the received internal temperature in the projector and the temperature threshold corresponding to the brightness level of the light-emitting unit.

[0096] In another implementable embodiment, the main controller may receive the ambient temperature in the environment where the projector is located. According to the correspondence relationship stored in advance in the memory associated with the main controller between the ambient temperature in the environment where the projector is located, the brightness level of the light-emitting unit, and the operating parameter of the heat dissipation unit, the main controller may determine the target operating parameter of the heat dissipation unit in the projector.

[0097] Optionally, the main controller may receive the internal temperature in the projector, the ambient temperature in the environment where the projector is located, and the brightness level of the light-emitting unit. According to the correspondence relationship stored in advance in the memory associated with the main controller between the internal temperature in the projector, the ambient temperature in the environment where the projector is located, the brightness level of the light-emitting unit, and the operating parameter of the heat dissipation unit, the main controller may determine the target operating parameter of the heat dissipation unit in the projector.

[0098] It can be seen that the main controller not only refers to the brightness level of the light-emitting unit in the projector, but also refers to the internal temperature in the projector and / or the ambient temperature in the environment where the projector is located to determine the target operating parameter of the heat dissipation unit in the projector, which can improve the accuracy of determining the target operating parameter of the heat dissipation unit in the projector and further improve the control accuracy of the main controller for heat dissipation of the heat dissipation unit.

[0099] Figure 3 It is a schematic flowchart of another projector control method provided by the embodiment of the present application. As Figure 3 shown, optionally, the above target operating parameter includes multiple sub-operating parameters, and each sub-operating parameter corresponds to attribute information. The above controlling the heat dissipation unit to dissipate heat according to the target operating parameter includes:

[0100] S301. Determine the target sub-job parameter according to the operation information associated with the projector and the attribute information corresponding to each sub-job parameter.

[0101] S302. Control the heat dissipation unit to dissipate heat according to the target sub-job parameter.

[0102] Wherein, the operation information includes operation duration information and / or temperature information, the temperature information includes: the internal temperature of the projector and / or the ambient temperature in the environment where the projector is located, the attribute information includes preset operation duration information and preset temperature information, and the preset temperature information includes: preset internal temperature and / or preset ambient temperature. The main controller can record in real time the current operation duration information of the projector and / or the internal temperature of the projector, and / or the ambient temperature in the environment where the projector is located.

[0103] In an implementable embodiment, each sub-job parameter is related to the target job parameter. For example, each sub-job parameter has a certain proportional relationship with the target job parameter. The attribute information corresponding to each sub-job parameter includes preset operation duration information and preset temperature information, and the preset temperature information includes: preset internal temperature and / or preset ambient temperature. After the main controller determines the target job parameter of the heat dissipation unit, it can determine the sub-job parameter matching the operation duration information from the sub-job parameters associated with the target job parameter according to the recorded current operation duration information of the projector and the preset operation duration information, and use the sub-job parameter as the target sub-job parameter to control the heat dissipation unit to dissipate heat.

[0104] In another implementable embodiment, it can be understood that when the heat dissipation unit in the projector is performing a heat dissipation operation, the internal temperature of the projector changes. Optionally, the ambient temperature in the environment where the projector is located may also change. Therefore, after the main controller determines the target job parameter of the heat dissipation unit according to the brightness level of the light emitting unit, it can determine the sub-job parameter matching the internal temperature of the projector and / or the ambient temperature in the environment where the projector is located from the sub-job parameters associated with the target job parameter according to the real-time recorded internal temperature of the projector and / or the ambient temperature in the environment where the projector is located and the preset internal temperature and / or preset ambient temperature, and use the sub-job parameter as the target sub-job parameter to control the heat dissipation unit to dissipate heat.

[0105] It can be seen that the main controller considers smaller granularity factors during the process of adjusting the job parameters of the heat dissipation unit in the projector, so that the heat dissipation unit can be controlled to dissipate heat more precisely.

[0106] Optionally, the determining the target sub-job parameter according to the operation information associated with the projector and the attribute information corresponding to each sub-job parameter includes:

[0107] Determine target attribute information from the attribute information corresponding to each sub-job parameter according to the operation information associated with the projector; use the sub-job parameter corresponding to the target attribute information as the target sub-job parameter.

[0108] Here, the operation information is taken as an example of operation duration information for illustration. Each sub-job parameter under the target job parameter corresponds to attribute information, and the attribute information can be stored in association with the target job parameter. The main controller can determine, according to the operation duration (such as t1) of the current projector, the attribute information with a preset operation duration information of t1 from the attribute information associated with the target job parameter, and use this attribute information as the target attribute information. The sub-job parameter corresponding to the target attribute information is the target sub-job parameter.

[0109] Figure 4 It is a schematic flowchart of another projector control method provided by an embodiment of the present application. As Figure 4 shown, optionally, the determining the target job parameter of the heat dissipation unit in the projector according to the temperature information associated with the projector and the brightness level of the light-emitting unit includes:

[0110] S401. Obtain the internal temperature detected by the internal temperature sensor in the projector.

[0111] S402. Determine the initial job parameter of the heat dissipation unit according to the corresponding relationship between the brightness level of the light-emitting unit and the job parameter of the heat dissipation unit.

[0112] S403. Determine the target job parameter of the heat dissipation unit according to the internal temperature, the temperature threshold corresponding to the brightness level of the light-emitting unit, and the initial job parameter.

[0113] Among them, the main controller is connected to the internal sensor preset in the projector, and is used to receive the internal temperature of the projector detected by the internal temperature sensor and store the internal temperature in the memory. After the main controller determines the initial job parameter of the heat dissipation unit according to the brightness level of the light-emitting unit, the initial job parameter can be processed accordingly according to the comparison result between the internal temperature and the temperature threshold corresponding to the brightness level of the light-emitting unit to obtain the target job parameter of the heat dissipation unit.

[0114] Specifically, there is a corresponding relationship between the brightness level of the light-emitting unit and the temperature threshold, and the corresponding relationship between the brightness level and the temperature threshold can be stored in the memory in advance. For example, when the brightness level of the light-emitting unit is brightness level 1, the corresponding temperature threshold is T1; when the brightness level of the light-emitting unit is brightness level 2, the corresponding temperature threshold is T2, and so on. When the brightness level of the light-emitting unit is brightness level n, the corresponding temperature threshold is Tn. Assume that the brightness level of the light-emitting unit is brightness level 1. Then, the internal temperature TR detected by the internal temperature sensor can be compared with the temperature threshold T1. When the internal temperature TR is greater than or equal to the temperature threshold T1, the initial operating parameter can be directly used as the target operating parameter of the heat dissipation unit. If the initial operating parameter is the duty cycle duty1, then duty1 is the target operating parameter of the heat dissipation unit. When the internal temperature TR is less than or equal to the deviation between the temperature threshold T1 and the preset value, the result after reducing the initial operating parameter (such as the rotation speed) by a preset degree (such as 15%) is used as the target operating parameter of the heat dissipation unit. Then, (duty1 - 15%) is the target operating parameter of the heat dissipation unit.

[0115] Among them, the preset values corresponding to different brightness levels can be the same, such as 4. Of course, they can also be different. The present application does not limit this. The preset degrees corresponding to different brightness levels can be the same or different. For example, as the brightness level increases, the specific value of the preset degree shows a decreasing trend. The present application does not limit this. For example, the preset degree corresponding to brightness level 1 is 15%, the preset degree corresponding to brightness level 2 is 14%, and the preset degree corresponding to brightness level 3 is 13%.

[0116] It can be seen that the main controller will compare the internal temperature of the received projector with the temperature threshold corresponding to the brightness level in real time, and dynamically determine the target operating parameter of the heat dissipation unit. This can improve the accuracy of the main controller to control the heat dissipation unit for heat dissipation. When the internal temperature of the projector is relatively low, on the basis of ensuring the heat dissipation effect, it can avoid excessive noise caused by too high a rotation speed of the heat dissipation unit.

[0117] Figure 5 It is a schematic flowchart of another projector control method provided by an embodiment of the present application. As Figure 5 shown, optionally, determining the target operating parameter of the heat dissipation unit in the projector according to the temperature information associated with the projector and the brightness level of the light-emitting unit includes:

[0118] S501. Obtain the ambient temperature detected by the ambient temperature sensor in the environment where the projector is located.

[0119] S502. Determine the target operating parameter of the heat dissipation unit according to the ambient temperature and the brightness level of the light-emitting unit.

[0120] Among them, the main controller is connected to an ambient temperature sensor pre-set in the environment where the projector is located, and is used to receive the ambient temperature detected by the ambient temperature sensor. The corresponding relationship between the ambient temperature, the brightness level of the light-emitting unit, and the operating parameters of the heat dissipation unit is pre-stored in the memory. When the main controller receives the ambient temperature of the environment where the projector is located and the brightness level of the light-emitting unit, the target operating parameters of the heat dissipation unit can be determined according to the pre-stored corresponding relationship.

[0121] It can be seen that the main controller can determine the target operating parameters of the heat dissipation unit based on the ambient temperature, which can avoid the influence of the ambient temperature on the operating parameters of the heat dissipation unit.

[0122] Figure 6 The flow diagram of another projector control method provided by the embodiment of the present application is as follows Figure 6 As shown, optionally, determining the target operating parameters of the heat dissipation unit in the projector according to the temperature information associated with the projector and the brightness level of the light-emitting unit includes:

[0123] S601. Obtain the internal temperature detected by the internal temperature sensor of the projector and the ambient temperature detected by the ambient temperature sensor in the environment where the projector is located respectively.

[0124] S602. Determine the initial operating parameters of the heat dissipation unit according to the corresponding relationship between the operating parameters of the heat dissipation unit, the ambient temperature, and the brightness level of the light-emitting unit.

[0125] Among them, the main controller is respectively connected to the internal sensor pre-set in the projector and the ambient temperature sensor in the environment where the projector is located, and is used to receive the internal temperature of the projector detected by the internal temperature sensor and the ambient temperature detected by the ambient temperature sensor. Based on this, the main controller can first determine the initial operating parameters of the heat dissipation unit according to the corresponding relationship between the ambient temperature pre-stored in the memory, the brightness level of the light-emitting unit, and the operating parameters of the heat dissipation unit.

[0126] S603. Determine the target operating parameters of the heat dissipation unit according to the internal temperature, the temperature threshold corresponding to the brightness level of the light-emitting unit, and the initial operating parameters.

[0127] Among them, after the master controller determines the initial operating parameters of the heat dissipation unit, the initial operating parameters can be updated according to the comparison result between the received internal temperature and the temperature threshold corresponding to the brightness level of the light-emitting unit. Specifically, assume that the brightness level of the light-emitting unit is brightness level 1, the ambient temperature is T0, the temperature threshold corresponding to brightness level 1 is T1, and the initial operating parameter determined according to brightness level 1 and ambient temperature T0 is duty ratio duty0. Then when the internal temperature TR is greater than or equal to the temperature threshold T1, duty0 can be directly used as the target operating parameter of the heat dissipation unit; when the internal temperature TR is less than or equal to the deviation between the temperature threshold T1 and the preset value, the result after reducing duty0 by a preset degree (such as 15%) is used as the target operating parameter of the heat dissipation unit, so (duty0 - 15%) is the target operating parameter of the heat dissipation unit.

[0128] It can be seen that the target operating parameter of the heat dissipation unit is jointly determined by the internal temperature of the projector, the ambient temperature of the environment where the projector is located, the brightness level of the light-emitting unit, and the temperature threshold corresponding to the brightness level of the light-emitting unit, which can improve the accuracy of the target operating parameter.

[0129] Figure 7 This is a schematic flowchart of another projector control method provided by an embodiment of the present application. As Figure 7 shown, the above-mentioned determination of the brightness level of the light-emitting unit in the projector includes:

[0130] S701. Obtain the ambient brightness detected by the brightness sensor in the environment where the projector is located.

[0131] S702. Determine the brightness level of the light-emitting unit according to the relationship between the ambient brightness and the brightness level of the light-emitting unit.

[0132] Among them, the master controller is connected to the brightness sensor pre-set in the environment where the projector is located for receiving the ambient brightness detected by the brightness sensor. The master controller can determine the light intensity level of the environment where the projector is located according to the ambient brightness. Specifically, the master controller can determine whether the environment where the projector is located is a strong light environment or a weak light environment according to the comparison result between the ambient brightness and the light intensity threshold. After determining the light intensity level of the environment where the projector is located, the brightness level of the light-emitting unit can be obtained according to the relationship between the ambient brightness and the brightness level of the light-emitting unit.

[0133] Specifically, when the environment where the projector is located is a weak light environment, the brightness level less than the ambient brightness can be determined as the brightness level of the light-emitting unit according to the preset difference in the relationship. The master controller can control the brightness state presented by the light-emitting unit according to the brightness level of the light-emitting unit, which can enable users to have a better viewing experience in a weak light environment.

[0134] When the environment where the projector is located is a strong light environment, the brightness level greater than the ambient brightness can be determined as the brightness level of the light-emitting unit according to the preset difference in this relationship. The main controller can control the brightness state presented by the light-emitting unit according to the brightness level of the light-emitting unit, so that users can have a better viewing experience in a strong light environment.

[0135] Optionally, the method may further include: if the brightness level of the light-emitting unit is greater than a preset brightness level threshold, controlling the air door adjusting device to open.

[0136] Specifically, when the main controller determines that the brightness level of the light-emitting unit is greater than the preset brightness level threshold, an opening control instruction can be sent to the air door adjusting device connected to it, so that the air door adjusting device opens for ventilation. Among them, the preset brightness level threshold can be the brightness level of level 8, that is, brightness level 8.

[0137] Figure 8 It is a schematic flowchart of another projector control method provided by an embodiment of this application. Optionally, as Figure 8 shown, the above determination of the brightness level of the light-emitting unit in the projector includes:

[0138] S801. Respectively obtain the internal temperature of the projector detected by the internal temperature sensor in the projector and the ambient temperature detected by the ambient temperature sensor in the environment where the projector is located.

[0139] S802. According to the temperature threshold corresponding to the brightness level of the light-emitting unit, determine the target temperature threshold as the temperature threshold with the smallest difference from the internal temperature.

[0140] After the air door adjusting device is opened, the internal temperature sensor preset in the projector can detect the internal temperature of the projector, and the ambient temperature sensor preset in the environment where the projector is located can detect the ambient temperature. Each brightness level corresponds to a temperature threshold. Compare each temperature threshold with the internal temperature, determine the temperature threshold with the smallest difference from the internal temperature, and use this temperature threshold as the target temperature threshold.

[0141] S803. Determine the brightness level of the light-emitting unit corresponding to the target temperature threshold as the brightness level.

[0142] After the target temperature threshold is determined, the brightness level corresponding to the target temperature threshold can be determined according to the correspondence between the temperature threshold and the brightness level. It should be noted that the brightness level corresponding to the target temperature threshold is actually not the brightness state actually presented by the light-emitting unit, but a virtual brightness level, or a brightness level corresponding to the internal temperature of the projector.

[0143] Optionally, determining the target operating parameters of the heat dissipation unit in the projector according to the brightness level of the light-emitting unit includes: determining the target operating parameters of the heat dissipation unit in the projector according to the corresponding relationship between the operating parameters of the heat dissipation unit, the ambient temperature, and the brightness level.

[0144] Among them, the corresponding relationship between the operating parameters of the heat dissipation unit, the ambient temperature, and the brightness level is pre-stored in the memory. The main controller can obtain the target operating parameters of the heat dissipation unit in the projector according to this corresponding relationship, the brightness level determined according to the above-mentioned target temperature threshold, and the ambient temperature.

[0145] It can be seen that when the brightness level is greater than the preset brightness level threshold, the air damper adjustment device can be controlled to open for ventilation. In this way, when the internal temperature decreases, the matching operating parameters of the heat dissipation unit can be automatically adjusted, that is, when the light-emitting unit has a high brightness level, the heat dissipation noise can be reduced, thereby improving the user's viewing experience.

[0168] Figure 10 FIG. is a schematic structural diagram of another projector control system provided by an embodiment of the present application. As Figure 10 shown, the projector 100 is further provided with a damper adjusting device 1000; the main controller 101 is connected to the damper adjusting device 1000 and is used to control the damper adjusting device 1000 to open when the target brightness level of the light emitting unit 102 is greater than a preset brightness level threshold.

[0169] Among them, when the main controller 101 determines that the brightness level of the light emitting unit 102 is greater than a preset brightness level threshold (such as brightness level 8), it can send an opening control instruction to the damper adjusting device 1000 connected thereto, so that the damper adjusting device 1000 opens for ventilation.

[0170] Figure 11 FIG. is a schematic structural diagram of a damper adjusting device provided by an embodiment of the present application. As Figure 11 shown, the damper adjusting device 1000 includes a switch component 1101 and a damper 1102; the main controller 101 is connected to the switch component 1101 and is specifically used to control the switch component 1101 to open the damper 1102 when the target brightness level of the light emitting unit 102 is greater than a preset brightness level threshold.
