Alternative embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Example 1
Fig. 1 is a flowchart of a control method of an air detection device according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S101, acquiring air parameter concentration in a room where an air detection device is located, and determining whether people exist in the room or not at the current time interval;
specifically, canDetecting the air parameter concentration in the room by an air detection sensor based on an air detection device; based on the light intensity collected by the light sensor, determining the current time period according to the light intensity; the presence of a person in a room is detected based on a human detection sensor. It should be noted that there are many air parameters, so the air detecting sensors include but are not limited to formaldehyde sensor, PM2.5 sensor, CO sensor2One or more of sensors, etc.
Step S102, adjusting the detection interval time of the air detection device according to the current time interval, whether people exist in the room and the air parameter concentration;
specifically, the corresponding first influence factor a may be determined according to whether a person is in the room, the corresponding second influence factor B may be determined according to the current time period, and the corresponding third influence factor C may be determined according to the air parameter concentration. Then, the preset interval time T is subjected to the first influence factor A, the second influence factor B and the third influence factor C0And adjusting to obtain the adjusted detection interval time T, and executing the detection operation of the next time or the next period according to the adjusted detection interval time T. The formula that can be referred to is as follows: t ═ T0+(T1*A)+(T2*B)+(T3C); wherein A is a first influence factor, B is a second influence factor, C is a third influence factor, T0Is a preset interval time which can be set as the minimum detection interval time, T, of the sensor1、T2、T3The values of the three can be the same or different, and T is the adjusted detection interval time.
It should be noted that the values of the first influence factor a, the second influence factor B, and the third influence factor C are not fixed values, and the value range is 0-1.
The value of the first impact factor a depends on whether a person is present in the room. If a person is in the room, the change of the air parameter is influenced, the air detection device needs to normally detect even more frequently, A is 0 or negative number, and T is1A is then 0 or a negative number. If no person is in the room, the detection interval of the air detection device can be slightly longerThe air parameter detection device has the advantages that the air parameter detection device is slightly increased, when no human activities exist in a room, the indoor air parameter changes slowly, the detection interval time can be properly increased, and the user cannot see the air parameters detected by the air detection device when no human activities exist, so that the user cannot be influenced to timely obtain the air parameters. Therefore, a is 1 or a value close to 1. The fact that a person is present in the room means that a moving object, such as a person, a dog, or a cat, is present in the room.
The value of the second influencing factor B depends on the current time period. When time division is carried out, the time division can be divided into a daytime time period with more people moving and a night time period with less people moving. If it is a day time period, B is 0, and if it is a night time period, B is 1 or a numerical value close to 1. That is, at night, the detection interval of the air detection device can be increased by T2Time, because the people has fallen asleep at night, indoor air parameter change also can be relatively slow, can suitably increase the detection interval time, and after the people fell asleep, the user can not see the air parameter that air detection device detected, so do not influence the user and in time obtain air parameter yet.
When the time interval is divided, different time interval division modes can be adopted according to different types of rooms, if the room type is a home, the time interval of the home, the rest time interval and the outgoing time interval can be divided in addition to the time interval of the day and the time interval of the night, for example, for office workers, the time interval from eight points earlier to six points later is the outgoing time interval, no person is in the home, the change of air parameters in the room is small, the influence of human activities is hardly caused, and B can be 0; from six nights to early morning, the time period of family is, the air parameters in the room can be influenced by the activity of people in the room, and B can be 1 or a value close to 1; the rest period is from early morning to eight morning, the person is basically asleep, the air parameters in the room are not changed greatly, and B can be 0.3. If the room type is an office place, the time period of day and the time period of night can be divided, the time period of day is more in personnel activity, the flow is larger, the air parameter change is more, and B can be 0; in the night period, people generally leave off work, no people exist in a room, great influence on the change of air parameters is avoided, and B can take a value of 1 or a value close to 1.
The value of the third influencing factor C depends on the air parameter concentration. Air parameters are divided into various categories, e.g. formaldehyde, PM2.5, CO2And the like, for different types of air parameters, a plurality of concentration ranges can be divided for different third influencing factors. For example, when PM2.5 detected by the PM2.5 sensor is in the range of 0-35ug/m3, C is 0; when PM2.5 is in the range of 36-75ug/m3, C is 0.3; when PM2.5 is in the range of 76-115ug/m3, C is 0.6; when PM2.5 is above 116ug/m3, C is 1. That is, when the PM2.5 is smaller, it is required to detect whether the PM2.5 is larger or not, so as to quickly find that the PM2.5 is larger and take measures to reduce the PM2.5 (such as turning on a fresh air fan, turning on a purifier, etc.), and when the PM2.5 is larger, it is required to reduce the PM2.5 for a longer time, so the detection interval time of the PM2.5 sensor can be slightly increased by T3C time without affecting the real-time nature of PM2.5 detection. Likewise, for CO2And other air parameters such as formaldehyde, and the like, and can also be set into a plurality of concentration ranges corresponding to different values of C.
T above1、T2、T3The values of the three parameters can be the same or different, and the specific values can be determined by referring to the influence of the three reference quantities (whether people exist in the room, the current time period and the detected air parameter concentration) on the detection interval time. For example, if the air parameters in the room are influenced a lot by someone in the room, T1Can be set in comparison with T2And T3Slightly larger.
This embodiment is according to whether someone in current period, the room to and the air parameter concentration that detects, the detection interval of the adjustment sensor of intelligence, under the normal detection of guaranteeing air parameter, and guarantee that the product uses the prerequisite of experiencing, increases the life of sensor, reduces the consumption. It should be noted that the timing of executing the present embodiment may be after each air detection operation by the air detection device, or may be periodically executed, that is, after the air detection device performs multiple air detection operations.
Example 2
The air detection device comprises an air detection sensor, a display screen, a human body detection sensor and a light sensor, wherein the air detection sensor at least comprises a formaldehyde sensor, a PM2.5 sensor and a CO sensor2One or more sensors capable of detecting at least temperature, humidity, formaldehyde, PM2.5, and CO2And displaying the detected values on a display screen for reference by a user. The human body detection sensor can detect whether people exist in a room where the air detection device is located, the light sensor can detect the light intensity of the current environment, and the current time period can be calculated according to the light intensity.
In order to ensure that the air detection device updates the air parameters in time when needed, and increase the service life of the air detection sensor and reduce the power consumption as much as possible, the embodiment provides an intelligent sensor detection interval control method. Fig. 2 is a flowchart of a sensor detection interval control method according to an embodiment of the present invention, as shown in fig. 2, the method including the steps of:
in step S201, the air detection device detects whether there is a person in the room, and if there is a person, a is 0, and if there is no person, a is 1. I.e. when the room is empty, the detection interval will be increased by T1Time.
In step S202, the air detection device detects whether the current time is day or night, and if it is day, B is 0, and if it is night, B is 1. That is, at night, the sensor detection interval time is increased by T2Time.
Step S203, the air detection device determines the value of C (the value of C is 0-1) according to the air parameter concentration detected by the corresponding sensor, and the detection interval time of the sensor is increased by T according to the current air parameter concentration3C time.
In step S204, the detection interval T of the air detection sensor of the air detection device is T ═ T0+(T1*A)+(T2*B)+(T3C). Wherein T is0The minimum detection interval time for the sensor.
The problem that the air detection device continuously detects to lead to life to shorten and the consumption increase has been solved to this embodiment, can guarantee air detection device's normal detection according to the adjustment of reference quantity self-adaptation next time or the detection interval time of next cycle, can increase sensor life again, reduces the consumption and avoids frequent detection.
