Referring to fig. 5, the temperature control method of the projector includes:

step S10, the projector processor collects the optical machine temperature, the circuit board temperature and the element temperature of the optical machine, the PCB and the DMD in real time and obtains a first rotating speed, a second rotating speed and a third rotating speed of an optical machine fan, a circuit board fan and an element fan;

the projector processor acquires the temperature of the optical machine, the temperature of the circuit board and the temperature of elements of the temperature equalizing plate connected with the optical machine, the PCB and the DMD in real time based on the temperature sensor, and synchronously acquires the first rotating speed, the second rotating speed and the third rotating speed of the fan of the optical machine, the fan of the circuit board and the fan of the elements in real time.

Step S20, the projector processor respectively sends the first tolerance temperature, the second tolerance temperature and the third tolerance temperature of the optical machine, the PCB and the DMD, and the maximum rotating speed of each fan to a mobile phone of a user; the projector establishes communication connection with the mobile phone based on the communication module;

the optical machine fan, the circuit board fan and the element fan can be fans with the same specification generally, and the maximum rotating speeds can be basically the same. The tolerance temperature refers to an extreme temperature range which can be borne by the optical machine, the PCB and the DMD in normal work without damage, the tolerance temperatures of the optical machine, the PCB and the DMD are different due to different materials and different normal working temperature requirements, and the tolerance temperatures of the optical machine, the PCB and the DMD are different, for example, the first tolerance temperature of the optical machine is 70 ℃, the second tolerance temperature of the PCB is 60 ℃, and the third tolerance temperature of the DMD is 50 ℃. The projector establishes wireless communication connection with the mobile phone through a wireless communication technology, and after the projector establishes connection with the mobile phone, the projector withstands the first temperature. The second tolerance temperature, the third tolerance temperature and the maximum rotating speed of the optical machine fan, the circuit board fan and the element fan are transmitted to the mobile phone of the user.

Step S30, the mobile phone establishes and displays a first bar frame, a second bar frame and a third bar frame for adjusting the rotating speed for the optical machine fan, the circuit board fan and the element fan respectively according to the received maximum rotating speed; the mobile phone dynamically adds and displays corresponding progress bars for the first bar frame, the second bar frame and the third bar frame respectively according to the proportional relation between the first rotating speed, the second rotating speed and the third rotating speed and the maximum rotating speed, wherein the larger the rotating speed is, the longer the rotating speed is, and the longer the corresponding progress bar is;

referring to fig. 3, a first real-time rotation speed of the optical machine fan corresponds to a first bar-shaped frame progress bar, a second real-time rotation speed of the circuit board fan (i.e., a PCB fan) corresponds to a second bar-shaped frame progress bar, a third real-time rotation speed of the element fan (i.e., a DMD fan) corresponds to a third bar-shaped frame progress bar, and the longer the percentage of the progress bars is, the larger the real-time wind speed of the corresponding fans is.

Step S40, the mobile phone establishes and displays a fourth bar frame, a fifth bar frame and a sixth bar frame for temperature adjustment for the optical machine, the PCB and the DMD respectively with the received first tolerance temperature, the second tolerance temperature and the third tolerance temperature, wherein the larger the tolerance temperature is, the longer the temperature-dependent bar frame is; the mobile phone dynamically adds and displays corresponding progress bars for the fourth bar-shaped frame, the fifth bar-shaped frame and the sixth bar-shaped frame respectively according to the temperature of the optical machine, the temperature of the circuit board and the temperature of elements, and the temperature is higher and the related progress bars are longer;

referring to fig. 3, in general, fig. 3 is a display interface of a mobile phone screen, where the optical engine has the largest tolerable temperature, the PCB has the second tolerable temperature, and the DMD has the smallest tolerable temperature, so the fourth bar frame of the optical engine has the longest tolerable temperature, the fifth bar frame of the PCB has the second tolerable temperature, the sixth bar frame of the DMD has the shortest tolerable temperature, and the DMD temperature (i.e., the component temperature) progress bar percentage in fig. 3 is the largest, exceeds the preset early warning value (i.e., the progress bar exceeds the preset early warning value mark), the sixth bar frame progress bar mark is the preset highlight color, and since the progress bar percentages of the optical engine temperature and the PCB temperature (i.e., the circuit board temperature) do not exceed the preset early warning value, the progress bars of the fourth bar frame and the fifth bar frame are displayed in the preset soft color.

Step S50, the mobile phone synchronously adjusts the percentage of the progress bars of the first bar frame, the second bar frame and the third bar frame based on the rotating speed adjusting instruction input by the user based on the percentage of the progress bars of the fourth bar frame, the fifth bar frame and the sixth bar frame; the mobile phone synchronously sends the adjusted progress bar percentages of the first bar frame, the second bar frame and the third bar frame to the projector;

step S60, the projector processor adjusts the first rotation speed, the second rotation speed, and the third rotation speed of the optical machine fan, the circuit board fan, and the element fan, respectively, according to the received adjusted percentage of the progress bar.

The user sees the fourth bar frame, the fifth bar frame and the sixth bar frame about the temperature display of the three heat sources of the optical machine, the PCB and the DMD, and the user can input rotating speed adjusting instructions of the percentage of the progress bars of the fourth bar frame, the fifth bar frame and the sixth bar frame to the mobile machine.

In addition, in order to guide the more efficient adjustment ray apparatus of user, three big heat source fan rotational speeds of PCB and DMD projecting apparatus and ambient temperature, this application shadow appearance temperature control method still includes:

step A, when the mobile phone detects that one or more of the percentage of the progress bars of the fourth bar frame, the fifth bar frame and the sixth bar frame are larger than a preset early warning value, the mobile phone outputs high-temperature early warning information to prompt a user to adjust the rotating speed of each fan of the projector until the percentage of the progress bars of the fourth bar frame, the fifth bar frame and the sixth bar frame is smaller than the preset early warning value, and the mobile phone stops outputting the high-temperature early warning information.

Therefore, when the temperature of the temperature-related bar frames (namely the fourth bar frame, the fifth bar frame and the sixth bar frame) exceeds the standard and the percentage of the progress bars exceeds the preset early warning value, the mobile phone outputs high-temperature early warning information to prompt a user to preferentially adjust the rotation speed-related bar frames (namely the first bar frame, the second bar frame and the third bar frame) corresponding to the exceeding standard until the percentage of the progress bars of the temperature-related bar frames is smaller than the preset early warning value.

Specifically, the step of outputting the high-temperature early warning information by the mobile phone in the step a includes:

step A1, when the percentage of the progress bar of the fourth bar is larger than a preset early warning value, the mobile phone marks the progress bar of the fourth bar as a preset highlight color, and marks a rotation speed increasing label on the first bar;

step A2, when the percentage of the progress bar of the fifth bar-shaped frame is larger than a preset early warning value, the mobile phone marks the progress bar of the fifth bar-shaped frame as a preset highlight color, and marks a tag for increasing the rotating speed on the second bar-shaped frame;

step A3, when the percentage of the progress bar of the sixth bar frame is larger than a preset early warning value, the mobile phone marks the progress bar of the sixth bar frame as a preset highlight color, and marks a tag for increasing the rotating speed on the third bar frame.

The bar-shaped frame progress bar percentage that the temperature is relevant exceeds and presets the early warning value, then correspond progress bar mark and be preset high bright colour, and increase the rotational speed label in step mark, for example, DMD temperature (being component temperature) progress bar percentage is the biggest in FIG. 3, exceed and preset the early warning value (being the progress bar and exceed and preset the early warning value mark), sixth bar-shaped frame progress bar mark is preset high bright colour, because ray apparatus temperature and PCB temperature (being circuit board temperature) progress bar percentage does not exceed and preset the early warning value, so the progress bar of fourth bar-shaped frame and fifth bar-shaped frame is shown with presetting soft colour. Therefore, the progress bar related to the fan rotating speed needing to be adjusted preferentially can be rapidly determined by the user through the differential display of the preset highlight color, the preset highlight color progress bar can be adjusted timely, and the corresponding projector heat source piece can be cooled timely.

In this embodiment, by detecting and displaying real-time temperatures of three heat source elements, namely, the projector optical machine, the PCB and the DMD, in real time in the mobile phone by the bar frame, and synchronously detecting and displaying real-time rotation speeds of fans near the three heat source elements, namely, the optical machine fan, the circuit board fan and the element fan, in real time in the mobile phone by the bar frame, a user can dynamically adjust the real-time rotation speeds of the fans of the three heat source elements based on the relationship between the real-time temperatures of the three heat source elements and the tolerance temperature, because the three heat source elements are arranged in the same heat dissipation channel and are all connected with the heat pipes passing through the heat dissipation channel, the increase of the rotation speeds of the fans of the three heat source elements can increase the airflow velocity in the heat dissipation channel, the increase of the rotation speed of the fan of one heat source element can increase the heat dissipation efficiency of the other two heat source elements, and the heat dissipation efficiency of the three heat source elements is correlated with the rotation speeds of the fans of the three heat source elements, the user dynamically and comprehensively adjusts the fan rotating speeds of the three heat source parts to adjust the temperatures of the three heat source parts, the phenomenon that the rotating speed of a single fan is too high and the noise is too high is avoided, the phenomenon that the three heat source parts are damaged due to too low rotating speed of the fan is also avoided, the fan rotating speeds of the three heat source parts are not required to be simultaneously increased or simultaneously decreased due to too high temperature or too high noise of the three heat source parts, the heat dissipation influence of the three fan rotating speeds on the three heat source parts in the whole heat dissipation channel is considered, and the user can conveniently and quickly control the temperature of the projector based on collection and adjust the noise to be within an acceptable range.

Further, in another embodiment of the method for controlling the temperature of the projector according to the present application, a first sound sensor for detecting fan noise is disposed inside the projector, a second sound sensor for detecting environmental noise is disposed on a surface of the projector, both the first sound sensor and the second sound sensor are in communication connection with the processor, the projector sends the fan noise and the environmental noise to the mobile phone in real time, and the method for controlling the temperature of the projector further includes:

step B1, when the mobile phone detects that the decibel difference value between the fan noise and the environmental noise is greater than the preset decibel value, the mobile phone selects a normal-temperature strip frame which is not marked as the preset highlight color from the fourth strip frame, the fifth strip frame and the sixth strip frame;

the decibel difference value of the fan noise and the environmental noise is larger than a preset decibel value, the fact that the fan noise is larger than the environmental noise of a scene where the projector is located is shown, the influence of the fan noise on a user is larger, the fan noise is larger, at the moment, the normal-temperature strip-shaped frame which is not marked as a preset highlight color is selected from the fourth strip-shaped frame, the fifth strip-shaped frame and the sixth strip-shaped frame by the mobile phone, and the strip-shaped frame corresponding to the normal heat source temperature is selected to serve as the normal-temperature strip-shaped frame.

The decibel difference value of the fan noise and the environmental noise is smaller than or equal to a preset decibel value, the fact that the fan noise is smaller than the environmental noise indicates that the fan noise is smaller than the environmental noise, the influence of the fan noise on a user is smaller, the user can accept the fan noise at the moment, the fans of the three heat source parts are not adjusted, and all parts of the projector heat dissipation channel can normally run.

And step B2, marking the progress bar of the normal-temperature bar frame as a preset soft color by the mobile phone, marking a rotation speed reduction label on the target rotation speed bar frame corresponding to the normal-temperature bar frame and used for rotation speed adjustment, and continuously detecting the percentage of the progress bar of the fourth bar frame, the fifth bar frame and the sixth bar frame.

As shown in fig. 4, the fourth bar-shaped frame and the fifth bar-shaped frame are normal temperature bar-shaped frames, and the progress bar is a preset soft color, the sixth bar-shaped frame is a bar-shaped frame with a higher temperature, the progress bar of the sixth bar-shaped frame is a preset highlight color, the first bar-shaped frame corresponding to the fourth bar-shaped frame in fig. 4 and used for rotating speed adjustment is taken as a target rotating speed bar-shaped frame, the fifth bar-shaped frame corresponding to the second bar-shaped frame used for rotating speed adjustment is taken as a target rotating speed bar-shaped frame, so that a rotating speed reduction label is marked on the progress bars of the first bar-shaped frame and the second bar-shaped frame, the user is prompted to reduce the progress bars of the first bar-shaped frame and the second bar-shaped frame, and the progress bar percentages of the fourth bar-shaped frame, the fifth bar-shaped frame and the sixth bar-shaped frame are synchronously continuously detected.

In this embodiment, in the process of reducing the percentage of the progress bar of the target rotation speed bar frame by the user, the rotation speed of the corresponding fan decreases, and the user can simultaneously monitor and display the temperature change of the three heat source devices through the fourth bar frame, the fifth bar frame and the sixth bar frame, while reducing the rotation speed and the noise of the fan corresponding to the target rotation speed bar frame, the temperature bar progress bar of the three heat source devices of the projector does not exceed the preset early warning value mark, so that the mobile phone guides the user to adjust the rotation speed and the noise of the fan, and also controls the temperature of the three heat source devices within the normal range, and the mobile phone increases and decreases the rotation speed label to guide, and displays the mobile phone temperature and the rotation speed progress bar in real time The noise is minimized.

In addition, in another embodiment of the projector temperature control method, after the mobile phone outputs the high-temperature warning information, the projector temperature control method further includes:

step C, when the duration of the high-temperature early warning information output by the mobile phone is longer than the preset duration, the mobile phone controls the projector to reduce the use power of the components; when the mobile phone detects that any one of the percentage of the progress bars of the fourth bar frame, the fifth bar frame and the sixth bar frame is equal to 100%, the mobile phone controls the projector to be powered off and outputs high-temperature danger information.

After the mobile phone outputs the high-temperature early warning information, the mobile phone can count the duration of continuously outputting the high-temperature early warning information, that is, the mobile phone counts the duration of one or more of the three heat source elements with over-high temperature, if the duration of the high-temperature early warning information output by the mobile phone is longer than the preset duration, it indicates that the user does not adjust the fan speed of the three heat source elements in time or adjust the fan speed to achieve the expected cooling effect, and at this time, the mobile phone controls the projector to reduce the use power of the components in order to avoid the damage of the optical machine, the PCB or the DMD due to over-high temperature, such as reducing the power consumption of one or more of the optical machine, the PCB and the DMD, or directly reducing the power consumption of the heat source part corresponding to the bar-shaped frame outputting the high-temperature early warning information and corresponding to the temperature adjustment, as shown in fig. 3, the sixth bar-shaped frame triggers the high temperature early warning information, and the second bar-shaped frame corresponds to the DMD, so that the power consumption of the DMD is reduced. When the mobile phone detects that the percentage of the progress bar of the fourth bar frame, the fifth bar frame and the sixth bar frame is equal to 100%, the fact that the temperature of one or more heat source pieces reaches the tolerance temperature is shown, the heat source pieces are easily damaged at the moment, the situation is urgent, the mobile phone directly controls the projector to be powered off, high-temperature dangerous information is output, a user is prompted to pay attention to checking the heat dissipation situation of the projector, and therefore the projector is guaranteed not to be directly damaged due to overhigh temperature or untimely adjustment of the user.

Specifically, an air duct fan and a temperature sensor for detecting the outlet temperature at the heat dissipation outlet in real time are arranged at the heat dissipation outlet of the projector, the temperature sensor is in communication connection with the processor, and the projector sends the outlet temperature to the mobile phone in real time; the projector temperature control method further includes:

and D, when the mobile phone detects that the percentage of the progress bars of the first bar frame, the second bar frame and the third bar frame is greater than a preset early warning value, judging the temperature difference between the outlet temperature and the environment temperature of the projector, and if the temperature difference is less than a preset temperature difference value, outputting abnormal prompt of the heat dissipation outlet by the mobile phone to prompt a user to check the heat dissipation outlet of the projector.

An air duct fan is arranged at the heat dissipation outlet, airflow in a heat dissipation channel inside the projector is further guided to rapidly flow out from the heat dissipation outlet, a temperature sensor for detecting the temperature of the outlet is arranged at the heat dissipation outlet, when the mobile phone detects that the percentage of progress bars of the first bar-shaped frame, the second bar-shaped frame and the third bar-shaped frame is larger than a preset early warning value, the temperature of the three heat source pieces is still in a high-temperature early warning state after a user adjusts the fan rotating speed of an optical machine fan, a circuit board fan and an element fan of the three heat source pieces, at the moment, the temperature difference between the outlet temperature and the environment temperature of the projector is further judged, if the temperature difference is smaller than a preset temperature difference value, the outlet temperature is not much different from the environment temperature, the outlet temperature of the heat dissipation outlet is not much different from the room temperature, the heat inside of the projector is not effectively discharged through the heat dissipation channel, and the heat dissipation outlet is probably blocked, the mobile phone outputs a prompt for abnormity of the heat dissipation outlet to prompt a user to check the heat dissipation outlet of the projector. Meanwhile, the judgment process of the previous embodiment is continued, when the mobile phone detects that any one of the percentage of the progress bars of the fourth bar frame, the fifth bar frame and the sixth bar frame is equal to 100%, the mobile phone controls the projector to be powered off and outputs high-temperature danger information.

Furthermore, the projector temperature control method further includes:

step E1, the mobile phone detects the increasing speed of the percentage of the progress bars of the fourth bar frame, the fifth bar frame and the sixth bar frame in unit time;

step E2, if the increasing speed of the progress bar percentage of the fourth bar-shaped frame in unit time is greater than the preset speed value, the mobile phone increases the progress bar percentage of the first bar-shaped frame and synchronously and correspondingly increases the first rotating speed of the optical machine fan;

step E3, if the increasing speed of the percentage of the progress bar of the fifth bar-shaped frame in unit time is greater than the preset speed value, the mobile phone increases the percentage of the progress bar of the second bar-shaped frame and synchronously and correspondingly increases the second rotating speed of the circuit board fan;

step E4, if the rate of increase of the progress bar percentage of the sixth bar frame in unit time is greater than the preset speed value, the mobile phone increases the progress bar percentage of the third bar frame and synchronously increases the third rotation speed of the element fan correspondingly.

In order to avoid the situation that the temperature rising speed of the three heat source pieces is too high due to structural failure or heat dissipation failure and avoid the situation that a user cannot adjust the temperature too fast, when the mobile phone detects that the increase speed of the progress bar percentage of any one of the fourth bar frame, the fifth bar frame and the sixth bar frame in unit time is greater than a preset speed value, the mobile phone does not wait for user operation, the mobile phone directly increases the progress bar percentage of the bar frame corresponding to the adjusted rotating speed and synchronously increases the rotating speed of the heat element fan of the bar frame corresponding to the adjusted rotating speed correspondingly, a bottom-pocket temperature control protection process is provided, the three heat source pieces of the projector are ensured not to be burnt out by high temperature, the user can fully participate in the temperature control process of the projector, and an optimal scheme for controlling the rotating speed, noise and temperature of the projector under the current heat dissipation structure is gradually formed.
