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 control method for a gas water heater according to an embodiment of the present invention. The gas water heater control method provided in the embodiment is used in a scene where a gas water heater performs corresponding actions when a user approaches the gas water heater. The control method of the gas water heater provided by the embodiment can be executed by a main control board and a human body detection sensor of the gas water heater, and the main control board can be realized in a software mode and is integrated in the gas water heater. The control method of the gas water heater provided by the embodiment is automatically executed when the gas water heater is powered on.
The control method of the gas water heater provided by the embodiment specifically comprises the following steps: the gas water heater is provided with a human body detection sensor for detecting a human body, the human body detection sensor is used for detecting that the human body approaches to or leaves the gas water heater, and the gas water heater is controlled to execute corresponding actions according to the detection result.
The method provided by the embodiment can be considered that when the human body detection sensor detects a human body, the controller of the gas water heater can judge whether the human body is close to the gas water heater according to the detection data, and the gas water heater 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 approaches to or leaves from the gas water heater by a human body detection sensor;
and S102, the gas water heater executes corresponding actions.
Example two
The human body detection sensor is defined in this embodiment, and in this embodiment, the human body detection sensor is an infrared sensor, and the infrared sensor can detect a specific area at regular intervals, when a 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 as to determine that a user is close to or far from the gas water heater, and control the gas water heater to perform corresponding actions according to the determination 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 outside the maximum detection area of the infrared sensor when moving near the gas water heater.
The gas water heater control method provided by the embodiment has the following use scenes as an example:
when the gas water heater is in a power-on state, particularly when the gas water heater is in a standby or 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 gas water heater, and controls the gas water heater to execute corresponding actions according to the judgment result.
The control of the gas water heater to execute the corresponding action specifically means that the display screen is turned on or turned off, or the gas water heater is automatically turned on or turned off.
According to the method provided by the embodiment, when the user is located in the detection area of the gas water heater, the gas water heater 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 carried out, so that the fact that the user is close to or far away from the gas water heater is judged, and the gas water heater can execute corresponding actions according to the judgment result.
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, outputting a low-level signal by the infrared sensor according to a certain frequency;
s203, comparing low-level signal durations T1 and T2 obtained at two adjacent times;
and S204, judging whether the human body is close to or far from the gas water heater and controlling the gas water heater to execute corresponding actions.
EXAMPLE III
In this embodiment, the gas water heater control method provided by this embodiment can be automatically executed when the gas water heater 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 detection area of the gas water heater, 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 gas water heater or far away from the gas water heater 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 gas water heater;
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 gas water heater;
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 gas water heater 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 gas water heater.
The infrared sensor adopted in the embodiment has longer time for obtaining the low-level signal when the user is closer to the gas water heater; 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 gas water heater does not respond and the controller continues to obtain a low level signal duration output by the infrared sensor. At the moment, the distance between the human body and the gas water heater is larger than the distance between the user and the gas water heater 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, taking the turning on and off of the display screen as an example, referring to fig. 3, the method specifically includes the following steps:
s301, detecting that a human body is located in a specific area by an infrared sensor;
s302, the controller obtains the low-level signal time length T1 output by the infrared sensor;
s303, after the preset time, the controller obtains the time length T2 of the low-level signal output by the infrared sensor;
s304, judging | T2-T1If | exceeds a preset value T;
s305, if not, judging that the user shakes, and returning to S301;
s306, if yes, T is judged2Whether or not greater than T1；
S307, if yes, judging that the user approaches the gas water heater, lighting a display screen of the gas water heater and returning to S301;
and S308, if not, judging that the user is far away from the gas water heater, and returning to S301.
It should be noted that, when the controller determines that the user is close to the gas water heater, the display screen of the gas water heater is lighted; then, the infrared sensor still regularly carries out human body detection, and when the infrared sensor detected that the human body is kept away from gas heater, gas heater display screen extinguished.
In this embodiment, the corresponding actions executed by the gas water heater specifically include the following forms: the display screen of the gas water heater is lightened, the display screen of the gas water heater is extinguished and/or the gas water heater is turned on and off. In this embodiment, it is preferable that the display screen of the gas water heater is turned on or turned off.
The preset value T and the preset time are empirical values and are obtained according to multiple 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 effectual judgement user be close to or keep away from gas heater to make this gas heater reaction more sensitive, and more intelligent.
The embodiment also provides a gas water heater, wherein an infrared sensor is arranged on the gas water heater and used for detecting whether a user is close to or far away from the gas water heater, and the gas water heater works by using the gas water heater control method provided by the embodiment.
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.
