Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The wavelength of infrared rays is between 0.76 and 100 μm, and can be classified into near infrared, mid infrared, far infrared and far infrared according to the wavelength range, and its position in the electromagnetic spectrum is in the region between radio waves and visible light. Infrared radiation is the most widely-existing electromagnetic wave radiation in nature, and is based on the fact that any object can generate self irregular movement of molecules and atoms under the conventional environment, and continuously radiates thermal infrared energy, the more intense the movement of the molecules and atoms is, the more energy is radiated, and conversely, the less energy is radiated.

Objects with a temperature above absolute zero will radiate infrared rays due to their own molecular motion. After the power signal radiated by the object is converted into an electric signal through the infrared detector, the output signal of the imaging device can simulate and scan the spatial distribution of the surface temperature of the object in a one-to-one correspondence mode, and the spatial distribution is processed by the electronic system and transmitted to the display screen, so that a thermal image corresponding to the thermal distribution of the surface of the object is obtained. By using the method, the remote thermal state image imaging and temperature measurement of the target can be realized, and analysis and judgment can be carried out.

Vital signs are a group of medical parameters of personal health and physical function that can provide clues for disease recovery or timely diagnosis. There are four vital signs that are currently dominant and convenient to acquire: body Temperature (BT), blood Pressure (BP), respiratory rate (BR) and Heart Rate (HR), vital signs vary with age, sex, weight and health level, while at the same time one person's physical or psychological activities may also vary in a specific situation. For example, people engaged in physical activity may exhibit different body temperatures, respiratory rates, and heart rates.

Fig. 1 shows a system schematic diagram of an indoor monitoring system provided by the invention. As shown in fig. 1, the system includes: a monitoring device 101 and a central controller 102; the monitoring device 101 is disposed indoors and connected to the central controller 102, and is configured to transmit user characteristic data acquired indoors to the central controller 102; the central controller 102 adjusts the indoor environment based on the user characteristic data.

The millimeter wave radar is a high-precision sensor for measuring the relative distance, relative speed and azimuth of a measured object. Specifically, any object on the radar path will reflect back a signal and the radar system can determine the distance, speed and angle of the target by capturing and processing the reflected signal.

Millimeter wave radar emits chirps to the chest region of a person, and due to chest movement, the reflected signal is phase modulated, the modulation encompassing all components of movement, including heart beat and respiratory induced movement. The radar transmits a plurality of chirps according to a predetermined time interval. Each pulse performs a distance fast fourier transform and selects a distance bin corresponding to the chest position of the person. Each chirp records the phase of the signal in the selected range bin, thereby calculating the phase change and hence the velocity. The obtained velocity still includes all motion components. By performing a Doppler spectrum analysis of the obtained velocity, various components can be resolved.

The infrared camera is an imaging device integrating a camera, a protective cover, an infrared lamp, a power supply and heat dissipation unit and the like. Because the infrared light emitted by the human body and the heating object is stronger, the red light emitted by other non-heating objects is emitted, the infrared camera is adopted to realize not only night monitoring, but also human body temperature monitoring in the target range.

It can be understood that the indoor monitoring system provided in this embodiment includes a monitoring device 101 and a central controller 102, where the monitoring device 101 is used to monitor user characteristic data of an indoor user in real time.

According to the foregoing description, it is preferable that in a specific embodiment, the monitoring device 101 includes a millimeter wave radar for monitoring heart rate data, respiratory rate data, and position data of the indoor user in real time, and an infrared camera for acquiring body temperature data and image information of the indoor user in real time.

It should be noted that, the heart rate data, the respiratory rate data and the body temperature data can reflect the physical health condition of the indoor user to a certain extent; the position data can know the position of the indoor user in real time, and particularly, the position of the indoor user can be tracked in real time for the situation that some children can be hidden in some places when playing; the image information can assist the heart rate data, the respiratory rate data, the body temperature data and the position data, so that the accurate practical situation of indoor users is obtained.

Fig. 2 shows one of the monitoring schematic diagrams of the indoor monitoring system provided by the invention. As shown in fig. 2, millimeter wave radar can penetrate nonmetallic materials such as wood and textile, can detect whether someone in the room is hidden under the bed, in wardrobe, etc., children can be hidden in places which are difficult to find such as in the cupboard, under the bed, etc. when playing, sometimes enter a sleep state in these places, millimeter wave radar can find the position of the children in time, and remind guardians of the child position in time.

Based on the above, the millimeter wave radar can track a plurality of targets at the same time, that is, monitor the activity states of a plurality of children at the same time.

The central controller 102 is connected with the monitoring device 101, namely, is connected with the millimeter wave radar and the infrared camera at the same time, so that the millimeter wave radar and the infrared camera can forward the monitored user characteristic data of the indoor user to the central controller 102.

The central controller 102 may be a CPU, ASIC (Application Specific Integrated Circuit, specific integrated circuit) or DSP (Digital Signal Processing, digital signal processing circuit), the number of which may be one or more. The central controller 102 is interconnected with other devices via a communication bus, each device having a communication interface, the bus being coupled to the communication interface for data communication.

After the central controller 102 receives the heart rate data, the respiratory rate data and the position data of the indoor user monitored by the millimeter wave radar, and the body temperature data and the image information of the indoor user monitored by the infrared camera, if one or more of the data are found to be abnormal, that is, the data exceed the corresponding preset values stored in the central controller 102, the central controller 102 can timely send out an alarm to remind the user.

For example, when the infrared camera monitors that the body temperature of the indoor user is 40 degrees celsius, the body temperature of the indoor user is significantly higher than the normal body temperature value of the human body, and thus, the central controller 102 can send out an alarm.

Fig. 3 shows a second monitoring schematic diagram of the indoor monitoring system provided by the invention. As shown in fig. 3, the collected facial information of the child is transmitted to the central controller 102 by using an infrared camera, the identity of the child is determined through facial recognition, when the camera collects the facial information of the child, the infrared camera instantly measures the body temperature of the child, and when the temperature exceeds the normal temperature, a temperature abnormality alarm can be sent.

The central controller 102 may issue an alarm, which may be a voice alarm or a light alarm, and is not limited herein.

For example, in one particular embodiment, the infrared camera monitors that the indoor user's body temperature is 40 degrees celsius, and the 40 degrees celsius is significantly above the normal human body temperature value, so that the central controller 102 sounds a voice alarm.

In addition to giving an alarm when the physical condition of the indoor user is abnormal, the central controller 102 in this embodiment also adjusts the indoor environment according to the received heart rate data, respiratory rate data, body temperature data, position data, image information and other data, so as to help to improve the experience of the indoor user.

The indoor environment is adjusted, and the indoor environment is adjusted through the linkage of the central controller 102 and other intelligent devices in the room. Specifically, the adjustment of the indoor environment includes the adjustment of the indoor temperature, humidity and sound, and the adjustment of the indoor temperature may be achieved through an intelligent fan or an air conditioner, the adjustment of the indoor humidity may be achieved through an intelligent humidifier, and the adjustment of the indoor sound may be achieved through the control of a sound source.

It should be further noted that the indoor monitoring system provided in this embodiment may be suitable for all people, especially suitable for people such as children and old people who need to be attended to.

In this embodiment, the indoor monitoring system includes a monitoring device 101 and a central controller 102, where the monitoring device 101 includes a millimeter wave radar and an infrared camera, the millimeter wave radar is used to monitor heart rate data, respiratory rate data and position data of an indoor user in real time, the infrared camera is used to acquire body temperature data and image information of the indoor user in real time, and based on a connection relationship between the monitoring device 101 and the central controller 102, the millimeter wave radar and the infrared camera forward the monitored related data to the central controller 102, so that the central controller 102 sends an alarm according to these data when the related data is abnormal, and also adjusts the indoor environment. The system not only can monitor the physical condition of the indoor user in real time and effectively protect the indoor user, but also can adjust the indoor environment according to the actual condition of the indoor user, so that the indoor user can be in a comfortable state at any time, and the experience of the indoor user is effectively improved.

Further, the indoor monitoring system further includes: and the storage device is connected with the central controller 102 and stores the characteristic comparison data of the user characteristic data so as to assist the central controller to adjust the indoor environment.

Specifically, the storage device stores a combination of one or more of face recognition data, body temperature data, heart rate data, respiratory rate data, indoor point cloud data, and image information of an indoor user.

It will be appreciated that the indoor monitoring system includes a monitoring device 101, a central controller 102, and a storage device, where the storage device is connected to the central controller 102, the monitoring device 101 acquires body temperature data and image information of an indoor user in real time through an infrared camera, monitors heart rate data, respiratory rate data and position data of the indoor user in real time through a millimeter wave radar, and forwards the acquired data to the central controller 102, and the central controller 102 further transmits the data to the storage device, where the storage device stores the received data.

The body temperature data is data obtained through detection of an infrared camera or an infrared sensor, and the respiratory frequency data is human body data obtained through monitoring of millimeter wave radar. The image information is data obtained through real-time monitoring by the infrared camera.

Indoor point cloud data refers to a data set of points in a certain coordinate system in the room. The points contain rich information including three-dimensional coordinates X, Y, Z, color, classification values, intensity values, time, etc. The point cloud can be divided into two kinds in terms of composition characteristics, one is an ordered point cloud and one is an unordered point cloud.

The ordered point cloud is generally a depth map restored point cloud, and the ordered point cloud is arranged from the upper left corner to the lower right corner according to a map matrix line by line, and of course, some invalid points exist. Because the ordered point cloud is arranged in order, its neighboring point information can be easily found. Ordered point clouds are convenient in some processes, but in many cases ordered point clouds may not be available.

The unordered point cloud is a set of indoor space points, no sequence exists between the point arrangements, no influence exists after the sequence of the points is exchanged, the unordered point cloud is a common point cloud form, and the ordered point cloud can be treated as an unordered point cloud.

Indoor point cloud data can be obtained in four ways:

(1) The laser three-dimensional scanner uses the principle of laser ranging, and can quickly reconstruct three-dimensional model of the measured object and various drawing data such as lines, planes, bodies and the like by recording the three-dimensional coordinates, reflectivity, textures and the like of a large number of dense points on the surface of the measured object.

(2) And the depth camera projects light rays with structural characteristics onto the object to be detected through the near infrared laser, and depth information is acquired through the infrared camera.

(3) The binocular camera is used for acquiring two images of the measured object from different positions by using the two cameras, and calculating the three-dimensional coordinates of the points by calculating the position deviation of the corresponding points and using the triangle principle.

(4) And (3) reconstructing multiple views of the optical camera, providing a plurality of images and corresponding sets of image characteristic points thereof, and estimating the positions of the 3D points and the gestures of the camera.

It should be noted that, an area which is dangerous for young children in a room may be used as a key area, and point cloud data of the key area may be stored. For example, in one specific embodiment, an in-home door zone, a stove zone, a knife zone, a balcony railing zone, a window sill zone, a desk cabinet height, and the like are set as special zones, and coordinates thereof are stored as point cloud data in a storage device.

The storage device may be a high-speed RAM memory, a nonvolatile memory, a magnetic disk memory, or a solid state disk memory, which is not particularly limited herein.

In this embodiment, the indoor monitoring system further includes a storage device, where the storage device is configured to store face identification data, body temperature data, heart rate data, respiratory rate data, indoor point cloud data, and image information of an indoor user, and the storage device can be invoked at any time when the user needs the data, and at the same time, the storage device can also assist the monitoring device 101 to acquire some indoor user information.

Further, the indoor monitoring system further includes: the audible and visual alarm device is connected with the central controller 102, and sends out an alarm according to an alarm signal sent out by the central controller, namely, sends out one or more alarms of ringing alarms, lamplight flashing alarms and voice alarms when one or more of the received heart rate data, respiratory rate data, body temperature data, position data and image information are determined to be abnormal.

It will be appreciated that the indoor monitoring system includes a monitoring device 101, a central controller 102, and an audible and visual alarm device connected to the central controller 102, which can timely alarm when one or more of the received heart rate data, respiratory rate data, body temperature data, position data, and image information are abnormal.

It should be noted that, the alarm sent by the audible and visual alarm device includes, but is not limited to, a bell alarm, a light flashing alarm, and a voice alarm, which may send only one alarm of the foregoing alarm types, or may send multiple alarms of the foregoing alarm types at the same time, which is not limited herein.

The triggering condition for the audible and visual alarm device to issue an alarm may be one of heart rate data, respiratory rate data, body temperature data, position data, and image information, or may be a plurality of the foregoing data, which is not limited herein.

Taking the heart rate and respiratory rate of children as an example, in general, the normal range of heart rate and respiratory rate of children may fluctuate somewhat with age. The normal range of neonatal respiratory rate may be 40-60 beats/minute and the heart rate range is 110-150 beats/minute. With the age of children, the respiration and the heart rate are properly regulated, and the respiration is generally smoother, for example, the normal respiration rate of children over one year is 30-40 times/minute, and the heart rate may be 100-130 times/minute.

The heart rate of the school-age children may be 80-120 times/minute, and the breathing may fluctuate from 20-30 times/minute, all within the normal range. With further age, adolescent children may have a normal range of heart rates ranging from 60 to 100 beats per minute and breathing rates ranging from 15 to 25 beats per minute. The normal heart rate and respiratory range of children are all the former, and the smaller the age, the faster the respiratory frequency, the faster the heart rate. With age, heart rate and respiration both decrease.

If the monitored heart rate data and respiratory rate data are not in the normal fluctuation range, the audible and visual alarm device can send out an alarm.

Taking position data as an example, children often prefer to climb at will, and often climb to relatively dangerous areas, such as an indoor entrance door area, a stove area, a cutter area, a balcony railing area, a windowsill area and a desk and cabinet high position, when the millimeter wave radar monitors that the children enter the areas, a camera is called to aim at the areas to judge whether the children are in a dangerous state through images, and the central controller 102 is informed, so that the audible and visual alarm device is controlled to timely send out audible and visual alarms to inform the children of the danger.

In this embodiment, the indoor monitoring system further includes an audible and visual alarm device, where in the event of an abnormality in one or more of heart rate data, respiratory rate data, body temperature data, position data, and image information of the indoor user, one or more of a bell alarm, a light flashing alarm, and a voice alarm may be issued to inform that there is a possibility of danger.

Further, the indoor monitoring system further includes: the intelligent device is connected with the central controller 102, receives the real-time situation of the indoor user, and gives an alarm when the real-time situation is abnormal.

It will be appreciated that the indoor monitoring system includes a monitoring device 101, a central controller 102, and an intelligent device connected to the central controller 102, for receiving real-time situations of indoor users, and in case of anomalies in the received real-time situations, performing alarm processing.

Smart devices include all devices that can communicate, such as tablets, cell phones, smart watches, and applications software in tablets and cell phones. The real-time situation is the heart rate data, the respiratory rate data, the body temperature data, the position data and the image information of the indoor user mentioned in the above embodiment.

In a specific embodiment, when the millimeter wave radar monitors that a child enters a dangerous area, the camera is called to aim at the area to judge whether the child is in a dangerous state through images, and the central controller 102 is informed, so that the audible and visual alarm device is controlled to timely send out audible and visual alarms to inform the child of the danger, and relevant data are transmitted to the mobile phone application, so that a guardian can timely check the images, and timely take measures to protect personal safety of the child.

Fig. 4 shows a third monitoring schematic diagram of the indoor monitoring system provided by the invention. Still take the child as an example, as shown in fig. 4, the millimeter wave radar can monitor the position data of the indoor user in real time, when the millimeter wave radar monitors that the child falls down, climbs to a windowsill or other high place, is on a railing, approaches a kitchen range and opens a door for entering a house, the millimeter wave radar can call a camera to determine whether the child is in a dangerous state, the data monitored by the millimeter wave radar and the camera are transmitted to the central controller 102, and in the case of determining that the child is in danger, an audible and visual alarm device is controlled to send an alarm, and the real-time condition of the child is sent to an intelligent device (namely a mobile phone APP in fig. 4) for a guardian to remotely check, and alarm is given when necessary.

In this embodiment, the indoor monitoring system includes an intelligent device, where the intelligent device is connected to the central controller 102, and is configured to receive a real-time situation of an indoor user, and alarm when an abnormality occurs in the received real-time situation, and timely take relevant security measures to avoid unnecessary danger.

Further, the indoor monitoring system further includes: the temperature control device is connected with the central controller 102 and is used for adjusting the indoor temperature according to a first signal transmitted by the central controller, specifically, the first signal is generated by determining that the heart rate data reaches a first preset heart rate threshold value and the respiratory rate data reaches the first preset respiratory rate threshold value, so that the control device adjusts the indoor temperature according to the first signal.

Specifically, if the monitored heart rate data reaches a first preset heart rate threshold value, and the monitored respiratory rate data reaches the first preset respiratory rate threshold value, the temperature control device is controlled to adjust the indoor temperature.

It should be noted that if the monitored heart rate data does not reach the first preset heart rate threshold, or the respiratory rate data does not reach the first preset respiratory rate threshold, or both the heart rate data and the respiratory rate data do not reach the corresponding preset thresholds, the current indoor temperature is maintained, and the indoor temperature is not regulated.

The temperature control device is an intelligent device which can adjust indoor environment, such as an air conditioner, an intelligent fan and a dehumidifier. The first preset heart rate threshold and the first preset respiratory rate threshold are set according to the normal heart rate data and respiratory rate data of the human body.

In a specific embodiment, the first preset heart rate threshold is 88 times/min, the first preset respiratory rate threshold is 22 times/min, when the heart rate data and the respiratory rate data monitored in real time reach the relevant thresholds respectively, the heart rate and the respiratory rate of the user are both higher, and it can be inferred that the user is in a severe exercise state, so that the central controller 102 can control the temperature control device to adjust the indoor temperature in time, i.e. to reduce the indoor temperature and increase the air volume appropriately, so that the indoor user feels more comfortable in the exercise state.

In another specific embodiment, the first preset heart rate threshold is 62 times/minute, the first preset respiratory rate threshold is 16 times/minute, when the heart rate data and the respiratory rate data monitored in real time respectively reach the relevant thresholds, the heart rate and the respiratory rate of the user are lower, and the user can be inferred to be in a rest or sleep state, so that the central controller 102 can control the temperature control device to timely adjust the indoor temperature, namely, the indoor temperature is properly adjusted to be high, and the air supply quantity is properly reduced, so that the user is in a quiet and comfortable rest or sleep environment.

It should be noted that, the embodiment is particularly suitable for a scene where an indoor user is in a rest or sleep state, and reduces the volume of the indoor audio device to be turned off, so as to create a sound environment for the indoor user to fall asleep gradually.

In general, when an indoor user is in a resting or sleeping state, the corresponding heart rate data and respiratory rate data are relatively smooth.

For example, in a specific embodiment, the heart rate data of the indoor user is monitored to be 60 times/minute, the respiratory rate data of the indoor user is monitored to be 15 times/minute, and at this time, the heart rate and respiratory rate of the indoor user are low, so as to determine that the indoor user may be in a rest or sleep state, and if the indoor audio device is still detected to be in an on state at this time, the central controller 102 controls the sound control device to gradually reduce the volume of the indoor audio device in time until the sound control device is turned off.

It is to be understood that the user characteristic data of the indoor user may be obtained, where the user characteristic data may be one or more of the body temperature, heart rate, respiratory rate, blood pressure, etc. of the indoor user, and is not limited herein.

In a specific embodiment, the user characteristic data is heart rate data and respiratory rate data of the indoor user, that is, heart rate data and respiratory rate data of the indoor user are acquired, and the regulation mode of the air conditioner is determined according to the acquired heart rate data and respiratory rate data. Specifically, heart rate data and respiratory rate data of the indoor user are acquired, and the heart rate data and the respiratory rate data can be acquired through millimeter wave radar.

The heart rate data and the respiratory rate data of the indoor user can be obtained in real time or according to a preset time period. The preset time period may be set according to the actual requirement of the user, and is not particularly limited herein.

According to the obtained heart rate data and the respiratory rate data of the indoor user, the current state of the indoor user can be judged, and specifically, if the obtained heart rate data and respiratory rate data are both higher, the current possible motion state of the user is indicated; if the acquired heart rate data and respiratory rate data are both low, it is indicated that the user may be in a resting or sleep state.

In order to enable the obtained current state of the indoor user to be more accurate, the position data of the indoor user can be obtained through the millimeter wave radar, and whether the indoor user is in a motion state can be accurately judged according to real-time change of the position data.

Under the condition of determining the current state of the indoor user, determining a regulation mode of the air conditioner corresponding to heart rate data and respiratory frequency data of the indoor user, namely determining the air temperature, the air supply air quantity, the air speed and the air direction which are suitable for the regulation mode, and controlling the air conditioner to execute the regulation mode.

In another specific embodiment, the user characteristic data is body temperature data of the indoor user, that is, body temperature data of the indoor user is acquired, and the regulation mode of the air conditioner is determined according to the acquired body temperature data. Specifically, the body temperature data of the indoor user is acquired, and the body temperature data can be acquired through an infrared sensor or an infrared camera.

Similarly, based on the acquired body temperature data of the indoor user, the current state of the user can be deduced to a certain extent, and then the adaptive regulation and control mode is determined according to the current state, so that the user is in a comfortable environment.

In yet another specific embodiment, the user characteristic data are heart rate data, respiratory rate data and body temperature data of the indoor user, and after acquiring the user characteristic data, a corresponding regulation mode is determined according to the user characteristic data, and the regulation mode is executed.

In this embodiment, by acquiring user feature data of an indoor user, a regulation mode of the air conditioner is determined according to the acquired user feature data, and the air conditioner is controlled to execute the regulation mode. According to the method, the current state of the indoor user is determined through the user characteristic data of the indoor user, so that the indoor environment is adjusted, the comfort of the indoor user is improved, and the experience of the indoor user is improved.

On the basis of the above embodiment, further, the method further includes: acquiring the current state of an indoor user; and determining a preset heart rate threshold corresponding to the heart rate data and a preset respiratory rate threshold corresponding to the respiratory rate data according to the current state.

It can be understood that the indoor user is in different states, and the heart rate data and the respiratory rate data corresponding to the indoor user have great differences, that is, even if the same heart rate data and respiratory rate data are obtained through monitoring, different regulation and control modes can be determined according to the different states of the indoor user.

Here, the current state in the present embodiment is different from the current state in the first embodiment of the control method of the air conditioner in the acquisition manner. In the above embodiment, the current state of the indoor user is inferred by monitoring heart rate data and respiratory rate data, and in the present embodiment, the current state of the indoor user is manually input or voice interactive input by the user or captured by a camera.

After the current state of the indoor user is obtained in the mode, a preset heart rate threshold value and a preset respiratory rate threshold value which respectively correspond to the monitored heart rate data and respiratory rate data are determined according to the current state.

It should be noted that the heart rate data and the respiratory rate data can represent the activity of the indoor user to some extent, and thus, in a specific embodiment, the current state includes at least a sleep state and a movement state.

For example, in a sleep state, the preset heart rate threshold and the preset respiratory rate threshold, respectively, corresponding to heart rate data and respiratory rate data are both low, while in an exercise state, the preset heart rate threshold and the preset respiratory rate threshold, respectively, corresponding to heart rate data and respiratory rate data are both high.

In a specific embodiment, a first preset heart rate threshold value and a first preset respiratory rate threshold value are determined according to the current state of the indoor user, and if the monitored heart rate data reach the first preset heart rate threshold value and the respiratory rate data reach the first preset respiratory rate threshold value, the indoor temperature is adjusted.

In another specific embodiment, a second threshold heart rate threshold and a second preset respiratory rate threshold are determined according to the current state of the indoor user, and if the monitored heart rate data reach the second preset heart rate threshold or the respiratory rate data reach the second preset respiratory rate threshold, image information of the indoor user is obtained, and an alarm is given.

It should be noted that, the first preset heart rate threshold value and the first preset respiratory rate threshold value are both within the range of normal vital signs of the human body, and the second preset heart rate threshold value and the second respiratory rate threshold value are limit values of normal vital signs of the human body, so when the heart rate data or the respiratory rate data reach the limit values of the normal vital signs of the human body, the user may have a potential life hazard and needs to be warned to prevent unnecessary injuries.

In this particular embodiment, particularly suitable for use in elderly and child scenarios, the elderly should normally have a respiratory rate of between 16-20 beats/minute, a heart rate of between 60-100 beats/minute, a school-age child should have a heart rate of between 80-120 beats/minute, and a respiratory rate of between 20-30 beats/minute.

Therefore, if the respiratory rate data of the old is lower than 16 times/minute, or higher than 20 times/minute, the respiratory rate data of the child is lower than 20 times/minute, or higher than 30 times/minute, or the heart rate data of the old is lower than 60 times/minute, or higher than 100 times/minute, and the heart rate data of the child is lower than 80 times/minute, or higher than 120 times/minute, the image information of the corresponding user is acquired, and an alarm is given.

In still another specific embodiment, a third preset heart rate threshold value and a third respiratory rate threshold value are determined according to the current state of the indoor user, if the monitored heart rate data reaches the third preset heart rate threshold value and the respiratory rate data reaches the third respiratory rate threshold value, the indoor environmental volume is acquired, and if the indoor environmental volume is detected to be larger than the preset volume value, the volume value of the corresponding sound source is adjusted to the preset volume threshold value.

It should be noted that the third specific embodiment herein is particularly applicable to a case where the user is in a sleep state, and thus, in a normal case, the third preset heart rate threshold is smaller than the first preset heart rate threshold, and the third respiratory rate threshold is smaller than the first respiratory rate threshold. And the second preset heart rate threshold and the second preset respiratory rate threshold are the largest or smallest of the respective preset thresholds.

In this embodiment, by acquiring the current state of the indoor user, determining different preset heart rate thresholds and preset respiratory rate thresholds according to the current state, and then adjusting and increasing the indoor temperature and volume by combining the monitored heart rate data and respiratory rate data, the comfort of the indoor user is increased.
