For easy understanding, a specific flow of an embodiment of the present invention is described below, referring to fig. 1, and in an embodiment of a method for automatically reducing power consumption of an intelligent display according to the embodiment of the present invention, the method includes the following implementation steps:
step 101, when an intelligent display is started, acquiring the temperature detected by a preset temperature sensor aiming at the intelligent display, and acquiring an image frame rate, wherein the image frame rate is the frame rate of image data transmitted to the intelligent display;
in this step, the acquiring the image frame rate includes:
acquiring image data transmitted to the intelligent display;
the frame rate of the image data is determined as an image frame rate.
In practical application, image data transmitted to the intelligent display can be obtained through a data transmission interface connected to the intelligent display; for example, the data transmission interface of the smart display may be set as an HDMI2.1 interface.
In practical application, the process of acquiring the image frame rate can also be realized through a preset intelligent display automatic power consumption reduction system (simply referred to as a system):
the system acquires the value in the first memory, when the value in the first memory is 1, the intelligent display is proved to be started, the system acquires the content which is transmitted by data and displayed on the display through a data transmission interface HDMI2.1 connected to the intelligent display, the system acquires the content which is displayed by the intelligent display every 3 minutes, and the system classifies the identified content into three grades according to the frame rate.
Grade one: still picture data; the system acquires the data content transmitted by the HDMI2.1 interface of the intelligent display data transmission interface, when the system recognizes that the frame rate of the data content is 0, the system judges the still picture data, and the system records the judged frame rate data result into the second memory;
grade two: low frame rate data; the system acquires the data content transmitted by the HDMI2.1 interface of the intelligent display data transmission interface, when the system identifies that the frame rate of the data content is more than 0 and less than 60 frames, the system judges that the data is low-frame-rate data, and the system records the judged frame-rate data result into the second memory.
Grade three: high frame rate data; the system acquires the data content transmitted by the HDMI2.1 interface of the intelligent display data transmission interface, when the system recognizes that the frame rate of the data content is more than 60 frames, the system judges that the data is high-frame-rate data, and the system records the judged frame-rate data result into the second memory.
In this step, before the acquiring the temperature detected by the preset temperature sensor for the smart display, the method further includes:
judging whether the intelligent display is connected with the same network with equipment of a user or not based on a network detection module;
if the intelligent display and the user equipment are connected with the same network, determining that the user state is a manned state, and outputting the user state through a preset output end, wherein the user state at least comprises a manned state and an unmanned state, the manned state is a state that the user is in a preset range of the intelligent display, and the unmanned state is a state that the user is not in the preset range of the intelligent display;
if the intelligent display is not connected with the same network with the equipment of the user, detecting the user state based on a preset human body induction sensor, and outputting the user state through a preset output end; and closing the intelligent display when the user state is an unmanned state.
In practical application, the network detection module may be set as a WiFi detection module;
the process of judging whether the intelligent display is connected with the same network with the equipment of the user based on the network detection module can be realized by the following steps:
when the intelligent display is started to be used, wiFi is automatically connected, the system acquires the WiFi connection condition of the intelligent display from the router information every 5 minutes, the WiFi connection condition is recorded into the memory A, the initial value of a variable l in the memory A is set to be 0, and when the intelligent display is started, the value of l becomes 1. The system obtains the connection condition of the personnel mobile phone equipment from the router information every 5 minutes, records the connection condition into a memory B, sets the initial value of a variable a in the memory B as 0, sets the initial value of the variable B in the memory B as 0, assigns a value of 1 when the mobile phone equipment is connected with WiFi, assigns a value of 0 and adds a value of 1 to the value of the variable B when the mobile phone equipment is disconnected with WiFi. (the variable a in the memory B records the condition that the mobile phone device is connected with the WiFi, the variable B in the memory B records the frequency of disconnecting the WiFi of the mobile phone device, and the meaning of the number of times of disconnecting is that the system acquires the connection condition of the mobile phone device every five minutes, and when the frequency of disconnecting the WiFi is more than 2 times, the system judges that the mobile phone device is disconnected for a long time, and possibly people leave the display).
Further, the detecting the user state based on the preset human body induction sensor includes:
detecting a preset range of the intelligent display based on a preset human body induction sensor to obtain a human body detection result;
if the human body detection result is that a person exists, determining that the user state is a person state;
and if the human body detection result is unmanned, determining that the user state is unmanned.
In practical application, the human body sensing sensor detects the preset range of the intelligent display based on the preset human body sensing sensor to obtain a human body detection result, as shown in fig. 4, the human body sensing sensor may be disposed near the preset range of the intelligent display, and a dashed arrow in the figure indicates the propagation direction of infrared rays.
In practical applications, the human body sensing sensor may be configured as a human body infrared sensor. The basic principle of the human body infrared sensor is that the infrared energy emitted by the surface of a human body is utilized and received by an infrared receiver arranged in the sensor receiver, so that the detection of the human body is realized, specifically, the human body induction sensor is provided with an infrared receiver arranged in the sensor receiver, and the infrared energy emitted by the surface of the human body can be perceived by the receiver. The human body has a constant body temperature, generally about 37 degrees, so that the infrared probe emits infrared rays with a specific wavelength of about 10UM, and the passive infrared probe works by detecting the infrared rays with the wavelength of about 10UM emitted by the human body. The infrared rays about 10UM emitted by the human body are enhanced by the Fei-mud filter and then gathered on the infrared induction source. The infrared induction source usually adopts a pyroelectric element, the element loses charge balance when receiving the change of the infrared radiation temperature of a human body, charges are released outwards, and a subsequent circuit can generate an alarm signal after detection processing.
Step 102, determining a refresh rate range based on an image frame rate and a preset refresh rate range table, and adjusting the refresh rate of the intelligent display to the refresh rate range;
in this step, the refresh rate range table has at least a frame rate threshold, and the refresh rate range includes at least a low refresh rate and a high refresh rate;
in practical applications, the low refresh rate may be set to a refresh rate range of 1hz to 60 hz, and the high refresh rate may be set to a refresh rate range of 60 hz to 120 hz;
the determining the refresh rate range based on the image frame rate and a preset refresh rate range table includes:
determining that the refresh rate range is a low refresh rate when the image frame rate is less than the frame rate threshold;
and when the image frame rate is not less than the frame rate threshold, determining the refresh rate range as a high refresh rate.
In practical applications, the frame rate threshold may be set to 60 hz or 30 hz or 10 hz.
In the step, the refresh rate of the intelligent display is adjusted to a refresh rate range, and the refresh rate of the intelligent display can be adjusted by setting a graphic driver of the display; for example, if the image frame rate is 1Hz, the refresh rate of the display may be adjusted to 1Hz and the backlight brightness reduced;
for another example, if the image frame rate is 0Hz, the refresh rate of the display may be adjusted to 0Hz and the backlight brightness reduced.
The traditional display technology refreshes the display at a constant rate, namely the refresh rate is fixed, and the content frame rate under different application scenes is not adapted, on one hand, the system power consumption can be automatically increased and the influence of battery life and the like can be undoubtedly caused under the application scenes with still pictures or low frame rate, and on the other hand, in the game scenes with high frame rate animation or heavy load, the output frame rate is not matched with the constant display refresh rate, and bad visual experience such as picture blocking and delay can be caused, so that the invention collects the frame rate requirements of different contents to regulate the refresh rate of the display.
Step 103, determining a temperature state based on the temperature and a preset temperature state table, and outputting the temperature state through a preset output end;
in this step, the temperature state table has at least a temperature threshold; for example, the temperature threshold may be set to 30 degrees or 40 degrees or 50 degrees;
in practical application, the temperature threshold value can be adjusted through the normal working temperature of the intelligent display;
the determining the temperature state based on the temperature and a preset temperature state table comprises the following steps:
when the temperature is greater than the temperature threshold, determining that the temperature state is a high temperature state;
and when the temperature is not greater than the temperature threshold value, determining that the temperature state is a low temperature state.
In this step, the preset output terminal may be set as a display, a speaker, or an output data interface;
the outputting the temperature state through a preset output end comprises the following steps: the temperature state is displayed through the display, broadcasted through the loudspeaker or output through the output data interface.
104, when the temperature state is a low-temperature state, determining adaptive power based on the refresh rate range, adjusting the power of a backlight source in the intelligent display to the adaptive power, and closing a heat dissipation module of the intelligent display; and when the temperature state is a high temperature state, starting a heat radiation module of the intelligent display.
In this step, said determining an adaptive power based on said refresh rate range includes:
acquiring the preset normal power of the backlight source;
when the refresh rate range is a high refresh rate, determining that the adaptive power is the normal power;
when the refresh rate is a low refresh rate, determining that the adaptive power is the product of the normal power and a preset power coefficient; for example, the power coefficient may be set to 0.9 or 0.8 or 0.7.
