Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings.
Example one
Fig. 1 is a flowchart of a method for controlling a household appliance according to an embodiment of the present invention. The household appliance control method provided by the embodiment is used for a scene that the household appliance performs corresponding actions when a user approaches. The household appliance control method provided by the embodiment can be executed by a main control board and an infrared sensor of the household appliance, and the main control board can be realized in a software mode and is integrated in the household appliance. The household appliance control method provided by the embodiment is automatically executed when the household appliance is powered on.
The method for controlling the household appliance provided by the embodiment specifically comprises the following steps: the household appliance is provided with an infrared sensor for detecting a human body, and is characterized in that the infrared sensor detects a specific area at regular intervals, when the human body is detected, the infrared sensor outputs a low-level signal according to a certain frequency, the time length of the low-level signal output last time is T1, the time length of the low-level signal output next time is T2, and the time lengths T1 and T2 are compared, so that the fact that a user is close to or far away from the household appliance is judged, and the household appliance is controlled to execute corresponding actions according to the judgment result.
The specific area refers to an area where the infrared sensor can detect the activity of a human body, and the specific area needs to be limited because the detection range of the infrared sensor is limited and the human body cannot be detected at any time when the human body moves near the household appliance.
The household appliance control method provided by the embodiment uses the following scenes for example:
when the household appliance is in a power-on state, particularly when the household appliance is in a standby state or a working state, the infrared sensor detects a specific area at regular intervals, when a human body is detected, the infrared sensor outputs low-level signals according to a certain frequency, the controller compares the duration of the two adjacent low-level signals, judges whether the human body is close to or away from the household appliance, and controls the household appliance to execute corresponding actions according to the judgment result.
The control of the household appliance to execute the corresponding action specifically means that the display screen is turned on or turned off, or the household appliance is automatically turned on or turned off.
According to the method provided by the embodiment, when the user is located in the household appliance detection area, the household appliance can obtain the low level signal and the low level signal duration according to a certain frequency, the duration of the two low level signals before and after comparison is used for judging that the user is close to or far away from the household appliance, and the household appliance can execute corresponding actions according to the judgment result.
Specifically, referring to fig. 1, the method specifically comprises the following steps:
s101, detecting that a human body is located in a specific area by an infrared sensor;
s102, outputting a low-level signal by the infrared sensor according to a certain frequency;
s103, comparing low-level signal durations T1 and T2 obtained at two adjacent times;
and S104, judging whether the human body is close to or far away from the household appliance and controlling the household appliance to execute corresponding actions.
Example two
In this embodiment, the method for controlling a home appliance provided by this embodiment can be automatically executed when the home appliance is powered on. Meanwhile, the electrical signal provided in this embodiment is a low level, and in this embodiment, the electrical signal is obtained by an infrared sensor, and the infrared sensor outputs a high level in a standby state, and outputs a low level signal when detecting a human body signal. Of course, in other embodiments, the low level signal may be obtained by an ultrasonic sensor.
Specifically, the low-level signal duration is linear with the distance between the infrared sensor and the user. Specifically, the closer the infrared sensor is to the user, the longer the low-level signal duration is, and the farther the infrared sensor is from the user, the shorter the low-level signal duration is.
When the infrared sensor detects that the user is located in the household appliance detection area, the infrared sensor outputs a low-level signal according to a certain frequency, and the time duration T1 and the time duration T2 of the low-level signal obtained before and after the low-level signal are compared, so that whether the user is close to the household appliance or far away from the household appliance is judged.
The comparison durations T1 and T2 specifically include:
if the T2 is larger than the T1 and the absolute value of the difference value between the T2 and the T1 exceeds a preset value, judging that the human body approaches the household appliance;
if the T2 is smaller than the T1 and the absolute value of the difference value between the T2 and the T1 exceeds a preset value, judging that the human body is far away from the household appliance;
and if the absolute value of the difference value between the T2 and the T1 does not exceed the preset value, judging that the human body is not in place.
It should be noted that, if the absolute value of the difference does not exceed the preset value, the controller determines that the human body shakes, and the household appliance does not respond and continues to compare the durations of the two adjacent low-level signals obtained again. The absolute value of the difference value is compared with the preset value because the human body may move forwards or move backwards for a certain distance when shaking, but the distance is small and is not enough to judge that the human body is close to or far away from the household appliance.
The infrared sensor adopted in the embodiment has longer time for obtaining the low-level signal when the user is closer to the household appliance; otherwise, the smaller the size is; the magnitude comparison between the comparisons T1 and T2 described above therefore typically includes determining whether T1 is greater than T2. When T1 is greater than T2, the household appliance does not respond, and the controller continues to obtain the low level signal output by the infrared sensor and the low level signal duration. At this time, the distance between the human body and the household appliance is larger than the distance between the user and the household appliance when the controller detects T2. It is understood that the controller periodically detects whether a low level signal is obtained and records the duration of the low level signal.
Specifically, referring to fig. 2, the method specifically includes the following steps:
s201, detecting that a human body is located in a specific area by an infrared sensor;
s202, the controller obtains the low-level signal time length T1 output by the infrared sensor;
s203, after the preset time, the controller obtains the time length T2 of the low-level signal output by the infrared sensor;
s204, judging | T2-T1If | exceeds a preset value T;
s205, if not, judging that the user shakes, and returning to S201;
s206, if yes, judging T2Whether or not greater than T1；
S207, if yes, judging that the user approaches the household appliance, and executing corresponding actions by the household appliance;
and S208, if not, judging that the user is far away from the household appliance, and returning to S201.
In this embodiment, the corresponding actions performed by the household appliance specifically include the following forms: the display screen of the household appliance is lightened, the display screen of the household appliance is extinguished and/or the household appliance is turned on and off. In this embodiment, it is preferable that the display screen of the home appliance is turned on or turned off.
The preset value T and the preset time are empirical values, which are obtained from a plurality of tests.
Because what compare in this embodiment is that two adjacent low level signal are long, this embodiment compares with prior art, and the data that obtain are more accurate, and then can effectually judge whether the user is close to or keep away from domestic appliance to make this domestic appliance response more sensitive.
The embodiment also provides a household appliance, wherein an infrared sensor is arranged on the household appliance and used for detecting whether a user is close to or far away from the household appliance, and the household appliance works by using the household appliance control method provided by the embodiment. The household appliance may be one of an electric water heater, a washing machine, a dishwasher or an air conditioner.
It is noted that the foregoing shows and describes the general principles and features of the present invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the present invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined by the appended claims and their equivalents.
