Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a flow chart of a first embodiment of a control method of an air conditioner with a monitoring function according to the present invention is shown. As shown in fig. 1, the method comprises the following steps:
s101, acquiring facial image information of all users in the air-conditioned room and grouping the users according to the facial image information of the users, wherein the user grouping at least comprises an old age group and a child group.
Specifically, after the air conditioner is powered on, at least one camera arranged on the air conditioner scans and collects facial image information of all users in an air-conditioned room. Because users in the air-conditioning room can change, in the operation process of the air conditioner, the camera periodically scans and collects facial image information of all users in the air-conditioning room. The air conditioner identifies the ages of all users in the face image information collected each time, and groups the users according to the ages. Algorithms for identifying age are well known to those skilled in the art and are widely used in the field of digital photography, are not important to the protection of the present invention, and will not be described in detail herein. The air conditioner control method provided by the invention has a monitoring function, and the user groups at least comprise an old age group and a child group, and other groups can be set according to the requirements of the user for some special occasions such as welfare houses and the like. The elderly group is preferably over 70 years of age and the children group is preferably under 10 years of age.
S102, collecting detection signals of the acceleration sensors worn by the aged group users and the children group users, and sampling and recording the detection signals of the acceleration sensors which are larger than a set value.
In particular, users entering an air-conditioned room wear acceleration sensors through wearable devices or similar smart devices. The air conditioner collects detection signals of acceleration sensors worn by the aged group users and the children group users. If the detection signal of the acceleration sensor is less than or equal to the set value, the air conditioner does not process the detection signal, and the user is judged to be in a normal activity state. If the detection value of the acceleration sensor is larger than the set value, the user is indicated to have a large-amplitude action. The air conditioner samples and records the detection signal of the acceleration sensor which is larger than a set value to further judge, and meanwhile, the user wearing the acceleration sensor is used as a sampling object.
S103, when at least one sampling signal from the acceleration sensor is received, the human body sign sensor arranged on the air conditioner continuously detects the sign signal of the sampling object according to the same frequency, and judges whether the sign signal is abnormal or not.
Specifically, when the air conditioner receives at least one sampling signal from the acceleration sensor, the user who outputs the sampling signal is determined as the sampling object, and whether the body is abnormal or not is further intelligently determined. The human body sign sensor arranged on the air conditioner starts to continuously detect the sign signals of the sampling object at the set same frequency. The human body sign sensor can be an infrared sensor for detecting the body surface temperature of a human body, and can also be a radar sensor for detecting the heart rate of the human body by sampling low-frequency waves fed back by the fluctuation of the thoracic cavity of the human body. The human body sign sensor may also be a combination of an infrared sensor and a radar sensor. According to medical data, the body surface temperature of the human body is relatively low and the heart rate is relatively low for the aged group. For the children group, the body surface temperature is relatively high, and the heart rate is relatively fast. After the air conditioner receives at least one sampling signal, the air conditioner continuously detects and samples the body surface temperature or the heart rate signal of a human body according to the same frequency, and preferably continuously detects three body surface temperatures and three heart rate signals as physical sign signals. If one of the sign signals belongs to a normal value, the sign signals are judged to be normal. And if the sign signals do not belong to the normal value, judging that the sign signals are abnormal.
And S104, if the continuously detected sign signals are abnormal, sending an alarm signal, and controlling the air conditioner to operate according to the sign signals.
Specifically, if all the sign signals are abnormal, for example, the body surface temperature of the human body is high, and the heart rate is also high, it is determined that the user may fall down. The falling down may be caused by emergency, such as hypertension, heart disease, etc., and the air conditioner prompts the family to confirm through the buzzer arranged on the air conditioner or through APP outputting alarm signals outwards. And simultaneously controlling the operation of the air conditioner. If the sign signal is abnormal, if the air conditioner is in the on state, the running state of the current air conditioner can be maintained. If the air conditioner is in the off state, the air conditioner is automatically started to keep the temperature of the air-conditioned room between 22 ℃ and 26 ℃, and the risk is reduced. If the body surface temperature of the human body is low, but the heart rate is high, the bleeding phenomenon of the user is probably high, and the blood loss is more than 10%, the air conditioner is controlled to be moderately heated, so that the time of the shock phenomenon of the user is delayed.
By the control method of the air conditioner with the monitoring function disclosed by the embodiment of the invention, whether old people, children and similar users needing special monitoring exist in an air conditioning room can be automatically judged, whether the users have the conditions of falling, injury and the like can be accurately judged, help-seeking information can be timely sent out, an environment beneficial to rescue is provided, and compared with a control mode of setting priority, the control method of the air conditioner with the monitoring function can automatically adjust the running state of the air conditioner according to different specific conditions, can respond to emergency situations and has the advantage of high intelligent degree.
Fig. 2 is a flowchart illustrating a control method of an air conditioner with a monitoring function according to a second embodiment of the present invention. As shown in the figure, while the above steps S101 to S104 are performed, in the present embodiment, a more humanized control method is provided.
In this embodiment, the air conditioner is operated to coordinate the operation of the various components of the refrigeration cycle with the objective of eliminating the deviation in user comfort. In this embodiment, specifically, as in step S2041, if the continuously sampled vital sign signals are normal, the air conditioner operates according to the comfort control mode. Since there may be multiple users in the air-conditioned room, as in steps S2051 and S2061, according to the principle of caring for the weak, one user with the largest deviation of comfort levels in the air-conditioned room is used as the control object, and the air conditioner is controlled to operate, so that the real-time human comfort level of the control object is equal to the standard human comfort level. When the acceleration sensor detection signal meeting the trigger condition is not received, the air conditioner can also work in a comfort control mode. And one user with the largest comfort deviation is taken as a control object.
In steps S2042, S2052, and S2062, if the continuously sampled sign signal is abnormal, the air conditioner operates according to the monitoring control mode. And the air conditioner automatically takes the sampling object as a correction control object according to the principle of the weak, and controls the action of the air conditioner, so that the real-time human body comfort level of the correction control object is equal to the standard human body comfort level. Because the real-time human body comfort level is obtained based on the real-time clothes wearing surface temperature under the specific environment of the user, the current state of the control object can be accurately reflected, and misjudgment can not occur. For example, when the heart rate of a sampling object with abnormal sign signals is too high (100 times/min-120 times/min) and the body surface temperature is low (such as the blood loss condition shown above), the air conditioner can automatically judge that the human body state of a user is cold, automatically adjust the frequency of the compressor, improve the indoor environment temperature, and not aggravate the symptoms of the user.
In addition, the control of human comfort in this embodiment does not depend on the SSD data model. No matter the air conditioner works in a heating state or a refrigerating state, the humidity of an air conditioning room can be kept within the range of 20% -60% within a period of time after the air conditioner is started, and in the range, human bodies basically cannot easily feel the influence of the humidity on the human bodies, and rescue measures (standard humidity of a ward, an emergency room and an ICU) are favorably taken. Particularly, for the functional requirements of the air conditioner with the monitoring function, the embodiment discloses a brand-new human body comfort degree calculation model which does not relate to indoor humidity.
Specifically, as shown in fig. 3, calculating the human comfort level includes the following steps.
S301, collecting the real-time clothing surface temperature Ts of the control object or the corrected control object.
Specifically, the real-time garment surface temperature Ts may be detected by an infrared sensor provided on the air conditioner.
S302, collecting the real-time building inner surface temperature Tq in the air-conditioned room.
Specifically, the building interior surface temperature Tq may be detected by a temperature sensor directly contacting a wall surface, a ceiling surface, or a floor surface, or may be detected by an infrared sensor or a thermal imager. The inner surface temperature Tq may be a surface temperature of a wall surface to which the air conditioner is mounted, a surface temperature of a wall surface facing the air outlet of the air conditioner, a temperature of a ceiling wall, or a temperature of the ground. For home users, other factors such as room temperature in the upper, lower, left and right neighborhoods, sunshine duration change caused by building orientation and the like can also influence the inner surface temperature of the air-conditioned room. Therefore, the real-time building interior surface temperature Tq is preferably an average value of the interior surface temperatures of all the interior walls of the air-conditioned room.
S303, collecting the real-time environment temperature Th in the air-conditioning room, wherein the real-time environment temperature Th is preferably the air inlet temperature of an air-conditioning air return inlet. The real-time clothing surface temperature Ts of the human body, the real-time building inner surface temperature Tq and the real-time environment temperature Th in the air-conditioning room are consistent in sampling frequency.
S304, calculating real-time human body comfort level C ', C' = hr (Ts-Tq) + hc (Ts-Th) by using real-time dressing surface temperature Ts, real-time environment temperature Th and real-time building inner surface temperature Tq, wherein hr and hc are constants, hr is radiation heat conductivity, and hc is convection heat conductivity. Generally, hr is 4W/m2From 5W/m DEG C2The value of hc is between 3W/m DEG C2From 4W/m DEG C2The temperature is between the DEG C. The radiative and convective thermal conductivities are typically fixed and stored in the controller of the air conditioner for ready deployment. Under normal conditions, the real-time clothing surface temperature Ts, the difference between the real-time environment temperature Th and the real-time building inner surface temperature Tq is not more than 1 ℃.
After the human body comfort level is obtained, the air conditioner is controlled to act, so that the human body comfort level C' of the control object or the corrected control object is equal to the standard human body comfort level C which is comfortable for the human body in the air-conditioned room. The standard human comfort level C is generally in the range of (-0.5, 0.5). The basic principle of the control is to timely meet the requirement of eliminating the deviation between the real-time human body comfort degree C' and the standard human body comfort degree C by controlling the refrigerant circulation quantity of the compressor and the refrigerant flow entering the indoor heat exchanger.
Specifically, the air conditioner stores the correlation between the human comfort degree deviation and the human state. Taking the standard human comfort level as an example of 0, when the deviation is within the range of (2.5, 3), the real-time human comfort level deviation is high, and the human state is uncomfortable. When the deviation is within the range of (1.5, 2.5), the real-time human comfort degree deviation is high, and the human state is relatively uncomfortable. When the deviation is within the range of (0.5, 1.5), the real-time human comfort degree deviation is lower, and the human state is more comfortable. The corresponding human body state is uncomfortable, uncomfortable and comfortable deviation value intervals, namely a first interval, a second interval and a third interval which are in one-to-one correspondence, and the threshold values of the first interval, the second interval and the third interval are sequentially decreased progressively and are not overlapped with each other, so that disorder in follow-up control is avoided. The deviation value of the first interval, the second interval and the third interval can be adjusted according to the type of the user in the air-conditioned room, for example, for the user with a sensitive physique, the length of each interval range can be reduced, and the upper limit threshold of the first interval is reduced, so that the comfort level of the user is improved. When the deviation is within the range of (0, 0.5), the human body feels comfortable and the air conditioner does not operate.
In order to effectively eliminate the deviation between the real-time human body comfort level C' and the standard human body comfort level C, an operation control strategy is allocated to each human body state in the air conditioner. And if the human body state is not comfortable, correspondingly allocating a first operation control strategy. And if the human body state is relatively uncomfortable, correspondingly allocating a second operation control strategy. And if the human body state is more comfortable, correspondingly allocating a third operation control strategy. And sequentially decreasing the upper limit of the target operation frequency of the compressor in the first operation control strategy, the second operation control strategy and the third operation control strategy.
The air conditioner samples a control object in an air-conditioning room or corrects the real-time clothes-wearing surface temperature Ts, the real-time building inner surface temperature Tq and the real-time environment temperature Th according to a set sampling frequency, calculates the real-time human body comfort level C ', further calculates the difference value between the real-time human body comfort level C ' and the standard human body comfort level C, judges the numerical value interval to which the difference value belongs, obtains the real-time human body state of a user according to the incidence relation between the deviation numerical value interval and the human body state, calls a corresponding operation control strategy according to the human body state, and controls the air conditioner to operate according to the operation control strategy, so that the deviation between the real-time human body comfort level C ' and the standard human body comfort level C is gradually reduced until the real-time human body comfort.
When the acceleration sensor detection signal meeting the trigger condition is not received, in order to achieve the purpose of energy saving, if the air conditioner is controlled to operate according to the third operation control strategy according to the real-time comfort level C' of the control object in the first detection and control process after the air conditioner is started, under the operation control strategy, the target frequency of the compressor is low, the deviation is small, the energy consumption is small, the deviation can be eliminated, the air conditioner can stably operate, and the load of the whole air conditioning room is stable. Under stable conditions, the real-time comfort level C' of the control object is sampled again after the first detection period after the target operating frequency of the third operating control strategy is reached. If the air conditioner is controlled to operate according to the second operation control strategy according to the real-time comfort degree C' of the control object in the first detection and control process after starting up, under the operation control strategy, the target frequency of the compressor is high, the deviation is large, the deviation can be eliminated by medium energy consumption, the air conditioner is controlled to operate stably, and the load of the whole air conditioning room fluctuates but the fluctuation is not large. Under such conditions, the human comfort level C' is sampled again after a second detection period after the target operating frequency of the second operation control strategy is reached. If the air conditioner is controlled to operate according to the first operation control strategy according to the real-time comfort degree C' of the control object in the first detection and control process after starting up, under the operation control strategy, the target frequency of the compressor is high, the deviation is large, the deviation can be eliminated to control the air conditioner to operate stably only with large energy consumption, and the load fluctuation of the whole air conditioner room is large. And under the condition of large fluctuation, sampling the real-time comfort degree C' of the control object again after a third detection period after the target operation frequency of the first operation control strategy is reached. The duration of the first detection period, the duration of the second detection period and the duration of the third detection period are gradually decreased, so that when the condition of the air-conditioned room is stable, the detection and control frequency is reduced, the lower-level control is kept, when the load of the air-conditioned room fluctuates but the fluctuation is not large, the detection action frequency and the control action frequency are ensured to a certain degree, the middle-level control is kept, and when the load fluctuation of the air-conditioned room is large, the high-frequency detection action and the control action are kept, and the high-level control is kept. It should be noted that the above-mentioned "lower", "higher" and "high" of the target frequency of the compressor do not mean that the absolute value of the target frequency is lower, higher or high, but rather the result of comparing the first upshifting of the target frequency in the three operation modes. The control process is also executed when the compressor is restarted after being stopped.
It should be further noted that, when calculating the deviation, the sign of the data may be reserved, and a separate storage unit may be reserved in the controller of the air conditioner to store the sign bit. The symbol represents the cold and heat of the user, and the four-way reversing valve is directly controlled to control the air conditioner to be in the running mode under the refrigeration or refrigeration working condition. Taking the standard human comfort level as 0 for example, when the deviation is within the range of (-3, -2.5), the human condition is very cold. When the deviation is within the range of (-2.5, -1.5), the human body state is cold. When the deviation is within the range of (-1.5, -0.5), the human body state is slightly cold, and the three value intervals correspond to a first operation control strategy, a second operation control strategy and a third operation control strategy under the heating working condition. Correspondingly, when the deviation is within the range of (2.5, 3), the human body state is very hot. When the deviation is within the range of (1.5, 2.5), the human body state is heat. When the deviation is within the range of (0.5, 1.5), the human body state is slightly hot, and the three value intervals correspond to a first operation control strategy, a second operation control strategy and a third operation control strategy under the refrigeration working condition. It is also possible to determine the cooling or heating mode first and use the absolute value of the deviation in calculating the deviation.

The specific steps of the control method are described in detail in the above embodiments, and are not described herein again, and the air conditioner using the air conditioner with the monitoring function has the same technical effect.
