In order to solve the above problem, in the present embodiment, a display control method is provided, and fig. 2 is a flowchart of the display control method according to the embodiment of the present invention, where the flowchart includes the following steps:
step S202, obtaining image information to be transmitted to display equipment for display through an input interface, and sending the image information to a signal output control unit;
in an exemplary embodiment, the image information includes, but is not limited to, pictures and videos.
Step S204, under the condition that the signal output control unit is in a human body induction control mode, detecting whether a target object exists in a preset range for multiple times through a human body sensor to obtain a target detection result;
it should be noted that the target object is a person, and a controller of the display device may determine a mode of the signal output control unit through the control switch, specifically, the mode of the signal output control unit includes, but is not limited to, a human body sensing control mode and a timing mode.
In an exemplary embodiment, in a case where the signal output control unit is in a timing mode, a target time period is acquired, where the display device displays a content corresponding to the display information in the target time period; under the condition that the current time is in the target time period, outputting the image information to the display equipment through an output interface by the signal output control unit for displaying; and in the case that the current time is not in the target time period, the image information is stopped to be output to the display device for display through an output interface by the signal output control unit.
In an exemplary embodiment, before detecting whether a target object exists in a preset range for multiple times by using a human body sensor and obtaining a target detection result, the detection range of the human body sensor needs to be adjusted from a first detection range to a second detection range in response to a target setting instruction, where the preset range is the second detection range, and the second detection range matches with a space where the display device is located. That is, it is necessary to match the detection range of the human body sensor with the space of the display device.
Step S206, when the target detection result indicates that the target object has left the preset range and the time length of the target object leaving the preset range is greater than or equal to a first preset time length, terminating, by the signal output control unit, outputting the image information to the display device through an output interface for displaying.
It should be noted that the target time period may be preset, or may be set by a user or a controller, and specifically, the user or the controller may set the target time period and the first preset time period at the mobile terminal, so as to obtain the target time period and the first preset time period sent by the mobile terminal.
Through the steps, whether the image information acquired from the input interface is output to the display device through the output interface for displaying is determined through the signal output control unit according to the target detection result detected by the human body sensor, and the image information is output to the display device through the output interface for displaying through the signal output control unit under the condition that the target detection result shows that the target object leaves the preset range and the time length of the target object leaving the preset range is greater than or equal to the first preset time length. And then through the intelligent realization equipment automatic triggering standby of signal output control unit and human body sensor, solved when the equipment self does not support the intelligence to get into the condition of standby mode, can't realize the problem of automatic triggering standby.
In an exemplary embodiment, after the step S204, the following steps are further included:
step S1: under the condition that the target detection result comprises N detection results obtained by N times of detection of the human body sensor, judging whether the N detection results comprise a current departure detection result, wherein N is a positive integer greater than or equal to 2, and the current departure detection result represents that the target object departs from the preset range;
step S2: and under the condition that the N detection results comprise the current departure detection result, the detection results after the current departure detection result are all first-type detection results, the first detection time of the current departure detection result is earlier than the second detection time of the last detection result in the N detection results, and the time interval between the first detection time and the second detection time is greater than or equal to the first preset time length, determining that the target detection result indicates that the target object leaves the preset range, and the time length of the target object leaving the preset range is greater than or equal to the first preset time length, wherein the first-type detection result indicates that the target object does not exist in the preset range.
That is, if the target detection result includes a detection result of the current leaving of the target object, and all detection results within a first preset time period after the current leaving detection result indicate that the target object does not exist within the preset range, it may be determined that the target object has left the preset range, and the time period during which the target object leaves the preset range is greater than or equal to the first preset time period.
Specifically, in an exemplary embodiment, the determining whether the N detection results include the current departure detection result may be implemented by: and when the N detection results are arranged according to the detection time sequence, the N detection results comprise a first type detection result appearing after M continuous second type detection results, and P continuous first type detection results appear after the first type detection result, the first type detection result is determined as the current leaving detection result, M and P are positive integers greater than or equal to 2, the first type detection result indicates that the target object does not exist in the preset range, and the second type detection result indicates that the target object exists in the preset range.
For better understanding, the following specific description is made, assuming that the first preset time period is 1 minute, the human body sensor performs human body detection every 10 seconds, and in the detection process, the following detection results are obtained according to the detection time sequence: (A, A, A, A, B, B, B, B), wherein A is the second type detection result, B is the first type detection result, that is, after the second type detection result appears for a plurality of times continuously, the first type detection result appears for the first time, and under the condition that a plurality of continuous first type detection results appear after the first type detection result, the first type detection result is determined as the current leaving detection result. And if the time for continuously generating the first type detection result is greater than or equal to a first preset time length, determining that the target object leaves the preset range and the time length for the target object to leave the preset range is greater than or equal to the first preset time length.
In an exemplary embodiment, when the N detection results are arranged according to the detection time sequence, a first detection result and a last detection result of T consecutive detection results of the N detection results are first-type detection results, and a proportion of the first-type detection result of the T detection results is greater than or equal to a preset first proportion threshold, determining a second type detection result of the T detection results as a misjudged detection result, and modifying the second type detection result in the T detection results into the first type detection result, wherein the first type detection result indicates that the target object exists within the preset range, the second type detection result indicates that the target object does not exist in the preset range, and T is a positive integer greater than or equal to 2; and/or the presence of a gas in the gas,
and under the condition that the N detection results are arranged according to the detection time sequence, the first detection result and the last detection result in the U detection results are the second type detection result, and the occupation ratio of the second type detection result in the U detection results is greater than or equal to a preset second ratio threshold, determining the first type detection result in the U detection results as a misjudged detection result, and modifying the first type detection result in the U detection results into the second type detection result, wherein U is a positive integer greater than or equal to 2.
Specifically, assuming that T consecutive detection results are (a, B, a), wherein the percentage of the second detection result a is greater than or equal to a preset first proportional threshold (80%), it can be determined that the first detection result B may be an abnormality in the human body sensor detection, and the first detection result B is modified into the second detection result a. By adopting the technical scheme, the detection result of the human body sensor can be revised, and misjudgment is avoided.
In an exemplary embodiment, in a case that the target detection result indicates that the target object has left the preset range and a leaving direction indicated by a movement trajectory of the target object is a preset direction range, the signal output control unit terminates outputting the image information to the display device through an output interface for display; and/or under the condition that the target detection result shows that the target object leaves the preset range and the sound of the target object is not detected within a second preset time after the target object leaves the preset range, the signal output control unit stops outputting the image information to the display equipment through the output interface for displaying.

And assuming that the second preset time period is 5 minutes, and the target detection result indicates that the target object has left the preset range and the sound of the target object is not detected within 5 minutes after the target object leaves the preset range, it indicates that the target object may be due to other reasons and is not watching the television, and further the television needs to be in a standby state, that is, the signal output control unit terminates outputting the image information to the television through the output interface for displaying.
In an exemplary embodiment, the human body sensor may determine whether the target object exists within a preset range by: generating a first magnetic field within the preset range; determining that a target object exists in the preset range under the condition that a second magnetic field is detected; determining that the target object does not exist within the preset range under the condition that the second magnetic field is not detected; wherein the target object generates an eddy current in the case of the first magnetic field, the eddy current generating the second magnetic field, the first magnetic field being opposite in direction to the second magnetic field.
Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (such as ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (such as a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.
