Description

Technical Field

[0001] The present invention relates to the technical field of smart home, and in particular to a digital media smart home control system. Background Art

[0002] With the continuous development of science and technology, people's daily life is becoming more and more scientific and intelligent, and modern people are also tending to live a healthy and comfortable life. In addition, people's demand for smart home systems is increasingly inclined to personalized environmental adjustment services, including ventilation, temperature, light, sound, etc. However, due to the different living habits of different residents, the residents' demands for living environment are often different; at the same time, changes in the external environment will also lead to changes in the indoor environment, affecting the residents' living experience, thus bringing new control requirements for the environmental adjustment of smart home systems.

[0003] In the existing technology, smart home systems often meet personalized needs through various media devices, such as smart lighting, smart air conditioning, smart fresh air system, smart curtains and smart sweeping robots for environmental adjustment. As for the health of residents, poor indoor hygiene and poor ventilation can easily lead to bacterial growth in the indoor environment, which in turn affects the health of residents.

[0004] As for indoor hygiene, in daily life, dust not only comes from outdoor dust entering through the gaps of doors and windows, but also comes from dust carried by people when going out, and dust generated in daily life, such as the metabolic tissue of humans or animals falling off, dust adsorbed by home appliances when working, and particles generated by wear and tear of furniture, etc. Even if it can be cleaned by a sweeping robot or manually in daily life, there are still dust accumulations in some corners. The dust accumulation will subsequently affect the indoor air along with the indoor air flow, reducing the living environment quality of the residents. Therefore, the present invention provides a personalized digital media smart home control system for reducing the generation of indoor dust accumulation and ensuring the comfort of the indoor environment. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a digital media smart home control system, which is used to reduce the generation of indoor dust accumulation and ensure the comfort of the indoor environment according to the living habits of the residents.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a digital media smart home control system, comprising a central air conditioning system for adjusting the temperature of an indoor environment, a fresh air system for exchanging air in the indoor environment, a sweeping robot for regularly cleaning indoor floor dust, an image capture module for obtaining corresponding life images of indoor residents, and a processing center for regulating the indoor environment; the processing center is also electrically connected to an infrared dust sensor for measuring the concentration of dust particles in the indoor air;

[0007] The processing center is also used to input and store indoor models, including the vent locations of the central air conditioning system, the outlet locations of the fresh air system, the ventilation channel directions of the fresh air system, the locations of the infrared dust sensors, and the shielding areas corresponding to indoor obstacles. The processing center is also used to identify and establish the activity areas of residents in different time periods based on life images, and then mark the activity areas in the indoor model based on different time periods to establish prediction models for different time periods.

[0008] The processing center is also used to record and store the cleaning route of the sweeping robot; it is also used to obtain the historical dust particle concentration corresponding to each infrared dust sensor before the current time period, and based on the real-time dust particle concentration corresponding to the same infrared dust sensor, compare the historical dust particle concentration with the real-time dust particle concentration for consistency. If they are consistent, the layout position of the infrared dust sensor is marked as a normal point in the indoor model; if they are inconsistent, the layout position of the infrared dust sensor is marked as an abnormal point in the indoor model;

[0009] The processing center is also used to compare the real-time dust particle concentrations corresponding to adjacent abnormal points in the indoor model. If the real-time dust particle concentrations of the abnormal points are greater than the real-time dust particle concentrations of the adjacent abnormal points, the layout location of the infrared dust sensor is marked as a dust accumulation area in the indoor model; if the real-time dust particle concentration of the abnormal point is inconsistent with the real-time dust particle concentration of the adjacent abnormal points, the gas flow trajectory is determined by the direction corresponding to the real-time dust particle concentration of the abnormal point being greater than the real-time dust particle concentration of the adjacent abnormal points, and then the gas flow trajectory is marked in the indoor model.

[0010] The technical principle of the above scheme is as follows: while the fresh air system and the central air-conditioning system continuously exchange gas and adjust the temperature of the indoor environment, the image capture module is used to obtain the occupants' activity area indoors to control the central air-conditioning system and ensure the comfort of the environment; while the indoor environment is cleaned by a sweeping robot, the cleaning route is adjusted by utilizing the change in dust particle concentration after ventilation to reduce dust accumulation in the indoor environment.

[0011] The above scheme has the following beneficial effects:

[0012] 1. This solution adjusts the position of the vents between the activity area and the central air-conditioning system to reduce the overlap of dust with the activity area where the residents are located, thereby reducing the impact of dust on the residents' home life.

[0013] 2. This solution uses the change in dust particle concentration of an infrared dust sensor to determine the direction of indoor air flow at the current time and the dust accumulation area to improve the cleaning efficiency of the sweeping robot and reduce the accumulation of indoor dust.

[0014] 3. This solution, by adjusting the cleaning route of the sweeping robot, can not only reduce the power consumption of the sweeping robot, but also ensure the cleaning effect.

[0015] Furthermore, the cleaning routes are divided into daytime cleaning routes, temporary cleaning routes and nighttime cleaning routes based on the prediction models of different time periods, wherein the daytime cleaning routes and nighttime cleaning routes are established based on the activity areas in the corresponding time periods, and the temporary cleaning routes are established based on the activity areas in the current time period as a reference.

[0016] Beneficial effects: The working and home time of residents are divided through prediction models of different time periods to reduce the impact of the sweeping robot on the residents and ensure the cleanliness of the indoor environment.

[0017] Furthermore, the control center is also used to pre-establish a cleaning route based on the gas flow trajectory, and then calculate the minimum distance between the gas flow trajectory and the active area and dust accumulation area based on the active area and dust accumulation area before each time period in the gas flow trajectory, establish a circular cleaning branch for the cleaning route based on the minimum distance, and then send the cleaning route to the sweeping robot.

[0018] Beneficial effect: The sweeping robot cleans along the gas flow trajectory, so that the dust driven by the indoor air flow direction can be cleaned in sequence, and a circulating cleaning branch is established through the minimum spacing to reduce the energy consumption of the sweeping robot.

[0019] Furthermore, the central air conditioning system is also used to measure the indoor ambient temperature and send the indoor ambient temperature to the processing center;

[0020] The processing center is used to compare the indoor ambient temperature with the set human body temperature. If the indoor ambient temperature is higher than the human body temperature, a cooling start instruction is sent to the central air conditioning system; if the indoor ambient temperature is equal to the human body temperature, a standby instruction is sent to the central air conditioning system; if the indoor ambient temperature is lower than the human body temperature, a heating start instruction is sent to the central air conditioning system.

[0021] The processing center is also used to adjust the cleaning route based on the sending of cooling start instructions and heating start instructions. When the central air-conditioning system executes the heating start instruction, the processing center will increase the lateral movement width of the cleaning route; when the central air-conditioning system executes the cooling start instruction, the processing center will reduce the lateral movement width of the cleaning route.

[0022] Beneficial effects: By comparing with the indoor ambient temperature, the central air-conditioning system is started up to intelligently control the stability of the indoor ambient temperature; due to the difference between the central air-conditioning system and the indoor temperature environment, the cold air sprayed by the central air-conditioning system will sink while the hot air will float, and the working conditions of the automatic sweeping robot can be adjusted to improve the cleaning effect.

[0023] Furthermore, the air outlet of the central air conditioning system is connected to a plurality of vents, and the vents are provided with fan blade mechanisms for changing the direction of air flow;

[0024] The processing center is also used to calculate the real-time distance between the activity area and each vent position based on the activity area in the current time period, and compare the real-time distance corresponding to a vent position with the set influence distance. If the real-time distance is greater than the influence distance, a sinking instruction is sent to the fan blade mechanism of the vent; if the real-time distance is less than the influence distance, a horizontal flow instruction is sent to the fan blade mechanism of the vent;

[0025] At the same time, the processing center is used to calculate the first interval distance between the dust gathering area and the active area in the current time period, and compare the first interval distance with the set first threshold value. If the first interval distance is greater than the first threshold value, a standby command is sent to the fan blade mechanism; if the first interval distance is less than the first threshold value, the second interval distance between the dust gathering area and each vent position is calculated, and the second interval distance corresponding to a vent position is compared with the set impact distance. If the second interval distance is greater than the impact distance, a reversing command is sent to the fan blade mechanism based on the direction of the vent position pointing to the dust gathering area; if the second interval distance is less than the impact distance, an interval wind speed increase command is sent to the central air-conditioning system.

[0026] Beneficial effect: Since indoor dust will change with the flow of air, the direction of the fan blade mechanism of the vent is changed to change the direction of the air blown out by the central air-conditioning system to directly contact the residents in the activity area, thereby improving the physical comfort of the residents.

[0027] Furthermore, the processing center is also used to obtain the real-time dust particle concentration of the infrared dust sensor corresponding to the dust gathering area marked as dust gathering area, and compare the real-time dust particle concentration with the set limit value. If the real-time dust particle concentration is greater than the limit value, a timely cleaning instruction is sent to the sweeping robot based on the position of the dust gathering area in the indoor model; if the real-time dust particle concentration is less than the limit value, a standby instruction is sent to the sweeping robot.

[0028] Beneficial effect: By focusing on monitoring the real-time dust particle concentration in dust accumulation areas, the excessive accumulation of dust in dust accumulation areas can be reduced, and the subsequent spread due to the activities of residents can be reduced, thereby reducing the difficulty of subsequent cleaning to maintain the cleanliness of the indoor environment.

[0029] Furthermore, infrared dust sensors are respectively arranged at the corners of the indoor rooms.

[0030] Beneficial effect: Since indoor air cannot directly blow the dust in the corners, the dust in the corners is prone to rotation and accumulation. Therefore, the infrared dust sensor can accurately determine the dust accumulation situation in the indoor environment to provide accuracy in the subsequent determination of dust accumulation areas.

[0031] Furthermore, the air outlet of the fresh air system is connected to a plurality of air outlets, and the fan mechanism is also located at the air outlet and the air inlet of the fresh air system; a ventilation channel is connected between adjacent air outlets, and the ventilation channel of the fresh air system is connected to the central air conditioning system; the fresh air system is also used to measure the real-time wind speed value in the ventilation channel, and send the real-time wind speed value to the processing center;

[0032] The processing center is also used to compare the real-time wind speed value with the set cleaning value. If the real-time wind speed value is greater than the cleaning value, a closing command is sent to the fan blade mechanism at the air outlet and the vent; if the real-time wind speed value is less than the cleaning value, a maintenance command is sent to the fan blade mechanism at the air outlet and the vent.

[0033] Beneficial effect: During the air connection between the fresh air system and the external environment, the external wind force generated by weather changes in the natural environment is used to clean and scrape away the dust accumulated in the ventilation duct, thereby reducing manual cleaning and keeping the fresh air duct clean.

[0034] Furthermore, the processing center is also used to adjust the connection status of the ventilation channel based on the working status of the central air-conditioning system when the real-time wind speed value is greater than the cleaning value; if the central air-conditioning system is in the startup state, it first sends a closing command to the fan blade mechanism at the air inlet, and then sends an intermittent closing command to the fan blade mechanism at the air outlet and the vent, and sends an intermittent starting command to the fan blade mechanism at the air inlet; if the central air-conditioning system is in the shutdown state, it sends a closing command to the fan blade mechanism at the air inlet and the vent.

[0035] Beneficial effect: When using external wind to clean the ventilation duct, the working state of the central air-conditioning system is adjusted to reduce the interference of external wind on the indoor environment during the cleaning of the ventilation duct, thereby ensuring the comfort of the indoor environment.

[0036] Furthermore, the processing center is also used to identify whether the current resident is in the activity area based on the life image. If so, a maintenance instruction is sent to the central air-conditioning system and the fresh air system; if not, a reversing instruction is sent to the fan blade mechanism at the air outlet and the vent, and a wind speed increase instruction is sent to the central air-conditioning system.

[0037] Beneficial effect: By monitoring the current activities of residents in the activity area, corresponding environmental control can be carried out to reduce dust accumulation in the activity area, thereby improving the overall cleanliness of the indoor environment.

[0038] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] The following is further described in detail through specific implementation methods:

[0044] Embodiment 1:

[0045] As attached Figure 1 and Figure 2 As shown: a digital media smart home control system, including a central air-conditioning system for adjusting the indoor environment temperature, a fresh air system for air exchange in the indoor environment, a sweeping robot for regularly cleaning indoor floor dust, an image capture module 4 for obtaining corresponding life images of indoor residents, and a processing center for regulating the indoor environment; the processing center is also electrically connected to an infrared dust sensor 5 for measuring the concentration of dust particles in the indoor air, and the infrared dust sensors 5 are respectively arranged at the corners of the indoor rooms; the central air-conditioning system is also used to measure the indoor environment temperature and send the indoor environment temperature to the processing center; the air outlet of the fresh air system is connected to a plurality of air outlets 2, and the fan blade mechanism is also located at the air outlet 2 and the air inlet of the fresh air system; a ventilation channel 1 is connected between adjacent air outlets 2, and the ventilation channel 1 of the fresh air system is connected to the central air-conditioning system.

[0046] In this embodiment, the image capture module 4 is used under the premise of complying with laws and regulations. The central air conditioning system, the fresh air system, the sweeping robot, the image capture module 4, the processing center and the infrared dust sensor 5 are all existing technologies and will not be described in detail in this embodiment.

[0047] The processing center is also used to input and store indoor models, which include the location of the vents 3 of the central air conditioning system, the location of the air outlets 2 of the fresh air system, the direction of the ventilation channel 1 of the fresh air system, the layout of the infrared dust sensor 5, and the shielding area corresponding to the indoor obstacles; the processing center is also used to identify and establish the activity areas of the residents in different time periods based on the life images, and then mark the activity areas into the indoor model based on different time periods to establish prediction models for different time periods;

[0048] The processing center is also used to input and store the cleaning routes of the sweeping robot. The cleaning routes are divided into daytime cleaning routes, temporary cleaning routes and nighttime cleaning routes based on the prediction models of different time periods. The daytime cleaning routes and nighttime cleaning routes are established based on the activity areas in the corresponding time periods, and the temporary cleaning routes are established based on the activity areas in the current time period as a reference.

[0049] The control center is also used to obtain the historical dust particle concentration corresponding to each infrared dust sensor 5 before the current time period, and compare the historical dust particle concentration with the real-time dust particle concentration based on the real-time dust particle concentration corresponding to the same infrared dust sensor 5. If they are consistent, the arrangement position of the infrared dust sensor 5 is marked as a normal point in the indoor model; if they are inconsistent, the arrangement position of the infrared dust sensor 5 is marked as an abnormal point in the indoor model;

[0050] The processing center is also used to compare the real-time dust particle concentrations corresponding to adjacent abnormal points in the indoor model. If the real-time dust particle concentrations of the abnormal points are greater than the real-time dust particle concentrations of the adjacent abnormal points, the arrangement position of the infrared dust sensor 5 is marked as a dust accumulation area in the indoor model; if the real-time dust particle concentrations of the abnormal points are inconsistent with the real-time dust particle concentrations of the adjacent abnormal points, the gas flow trajectory is determined by the direction corresponding to the real-time dust particle concentration of the abnormal point being greater than the real-time dust particle concentration of the adjacent abnormal points, and the gas flow trajectory is then marked in the indoor model. For example, after the change, the current dust particle concentration of the infrared dust sensor 5 is 5 particles / m 3 , the dust particle concentration of the adjacent infrared dust sensor 5 is 10 particles / m 3 , then 5 grains / m 3 Infrared dust sensor 5 points 10 particles / m 3 The infrared sensor 5 is the gas flow trajectory.

[0051] For example, as the air flow direction of the central air-conditioning system changes, the indoor air flow direction will be driven, so that the indoor dust will change with the flow of the indoor air, thereby causing the dust particle concentration of each infrared dust sensor 5 to change. The indoor air flow direction at the current time can be determined by the change in dust particle concentration. The air flow direction of the indoor environment at the current time can be determined by marking, so as to determine the dust accumulation area, and further adjust the cleaning route of the sweeping robot, thereby improving the cleaning efficiency of the sweeping robot and reducing the accumulation of indoor dust.

[0052] The control center is also used to pre-establish a cleaning route based on the gas flow trajectory, and then calculate the minimum distance between the gas flow trajectory and the active area and dust accumulation area based on the active area and dust accumulation area before each time period in the gas flow trajectory, establish a circular cleaning branch for the cleaning route based on the minimum distance, and then send the cleaning route to the sweeping robot.

[0053] For example, in the process of establishing a cleaning route, the sweeping robot cleans along the gas flow trajectory so that the dust driven by the indoor air flow direction can be cleaned in sequence, and a circulating cleaning branch is established through the minimum spacing to reduce the moving distance of the sweeping robot, reduce the energy consumption of the sweeping robot, and ensure the cleaning effect.

[0054] The processing center is used to compare the indoor ambient temperature with the set human body suitable temperature. If the indoor ambient temperature is higher than the human body suitable temperature, a cooling start command is sent to the central air-conditioning system; if the indoor ambient temperature is equal to the human body suitable temperature, a standby command is sent to the central air-conditioning system; if the indoor ambient temperature is lower than the human body suitable temperature, a heating start command is sent to the central air-conditioning system; the processing center is also used to adjust the cleaning route based on the sending of the cooling start command and the heating start command. When the central air-conditioning system executes the heating start command, the processing center increases the lateral movement width of the cleaning route; when the central air-conditioning system executes the cooling start command, the processing center reduces the lateral movement width of the cleaning route.

[0055] For example, when the indoor ambient temperature changes, the air delivered by the central air-conditioning system often has a large temperature difference with the indoor air; by comparing the indoor ambient temperature, the central air-conditioning system is started up to intelligently control the stability of the indoor ambient temperature; due to the gap between the central air-conditioning system and the indoor temperature environment, the cold air sprayed by the central air-conditioning system will sink while the hot air will float, making the dust flowing with the air easier to settle to the floor surface under the influence of the sinking of the cold air, so as to reduce the floating distance of the dust, so as to reduce the lateral movement distance of the sweeping robot; and the dust flowing with the air will increase the floating distance of the dust under the influence of the rising hot air, so as to increase the lateral movement distance of the sweeping robot, and then adjust the working conditions of the sweeping robot to improve the cleaning effect.

[0056] Embodiment 2:

[0057] The difference from Example 1 is that the air outlet of the central air-conditioning system is connected to a plurality of vents 3 , and the vents 3 are provided with fan blade mechanisms for changing the direction of air flow.

[0058] The processing center is also used to calculate the real-time distance between the activity area and each vent 3 position based on the activity area of ​​the current time period, and compare the real-time distance corresponding to a vent 3 position with the set influence distance. If the real-time distance is greater than the influence distance, a sinking instruction is sent to the fan blade mechanism of the vent 3; if the real-time distance is less than the influence distance, a horizontal flow instruction is sent to the fan blade mechanism of the vent 3; at the same time, the processing center is used to calculate the first interval distance between the dust accumulation area and the activity area of ​​the current time period, and compare the first interval distance with the set first threshold value. If the first interval distance is greater than the first threshold value, a standby instruction is sent to the fan blade mechanism; if the first interval distance is less than the first threshold value, a second interval distance between the dust accumulation area and each vent 3 position is calculated, and the second interval distance corresponding to a vent 3 position is compared with the set influence distance. If the second interval distance is greater than the influence distance, a reversing instruction is sent to the fan blade mechanism based on the direction of the vent 3 position pointing to the dust accumulation area; if the second interval distance is less than the influence distance, an interval wind speed increase instruction is sent to the central air-conditioning system.

[0059] For example, since indoor dust will change with the flow of air, the direction of the fan blade mechanism of the vent 3 is changed to change the direction of the air blown by the central air-conditioning system to directly contact the residents in the activity area, thereby improving the physical comfort of the residents. At the same time, by comparing the overlap between the dust accumulation area and the activity area, the central air-conditioning system is controlled to adjust the wind speed or the wind direction mechanism is controlled to perform reversal adjustment to reduce the overlap between the dust accumulation area and the activity area, thereby reducing the inhalation of dust by the residents when breathing, thereby ensuring the respiratory health of the residents, and providing a suitable indoor environment for the residents.

[0060] Embodiment 3:

[0061] The difference from Example 2 is that the processing center is also used to obtain the real-time dust particle concentration of the infrared dust sensor 5 corresponding to the dust gathering area marked, and compare the real-time dust particle concentration with the set limit value. If the real-time dust particle concentration is greater than the limit value, a timely cleaning instruction is sent to the sweeping robot based on the position of the dust gathering area in the indoor model; if the real-time dust particle concentration is less than the limit value, a standby instruction is sent to the sweeping robot.

[0062] For example, in dust-collecting areas, there is already a lot of dust, which is easily affected by external factors. By focusing on monitoring the real-time dust particle concentration in the dust-collecting areas, we can reduce excessive accumulation of dust in the dust-collecting areas and the subsequent spread due to the activities of residents, thereby reducing the difficulty of subsequent cleaning and maintaining the cleanliness of the indoor environment.

[0063] Embodiment 4:

[0064] The difference from Example 3 is that the fresh air system is also used to measure the real-time wind speed value in the ventilation channel 1, and send the real-time wind speed value to the processing center; the processing center is also used to compare the real-time wind speed value with the set cleaning value. If the real-time wind speed value is greater than the cleaning value, a closing command is sent to the fan blade mechanism at the air outlet 2 and the vent 3; if the real-time wind speed value is less than the cleaning value, a maintenance command is sent to the fan blade mechanism at the air outlet 2 and the vent 3.

[0065] For example, in the process of air connection between the fresh air system and the external environment, due to weather changes in the natural environment, the air entering the ventilation duct 1 will often have different flow rates. By comparing the real-time wind speed value with the cleaning value, the fan mechanism at the air outlet 2 and the vent 3 is controlled to be closed, so that the ventilation duct 1 is in a relatively sealed space, and the dust accumulated in the ventilation duct 1 can be cleaned and scraped away by the external wind force, so as to reduce manual cleaning and keep the fresh air duct clean.

[0066] The processing center is also used to adjust the connection status of the ventilation channel 1 based on the working status of the central air-conditioning system when the real-time wind speed value is greater than the cleaning value; if the central air-conditioning system is in the startup state, a closing command is first sent to the fan blade mechanism at the air inlet, and then an intermittent closing command is sent to the fan blade mechanism at the air outlet 2 and the vent 3, and an intermittent starting command is sent to the fan blade mechanism at the air inlet; if the central air-conditioning system is in the shutdown state, a closing command is sent to the fan blade mechanism at the air inlet and the vent 3.

[0067] In the process of using external wind to clean the ventilation duct 1, the working state of the central air-conditioning system is adjusted to control the external wind from entering the ventilation duct 1, thereby reducing the interference of the external wind on the indoor environment during the cleaning process of the ventilation duct 1 and ensuring the comfort of the indoor environment.

[0068] Embodiment 5:

[0069] The difference from Example 4 is that the processing center is also used to identify whether the current occupant is in the activity area based on the life image. If so, a maintenance instruction is sent to the central air conditioning system and the fresh air system; if not, a reversing instruction is sent to the fan blade mechanism at the air outlet 2 and the air vent 3, and a wind speed increase instruction is sent to the central air conditioning system.

[0070] For example, based on the current activities of the residents in the activity area, a reversing instruction is sent in time through the fan blade mechanism at outlet 2 and vent 3, and a wind speed increase instruction is sent to the central air-conditioning system to blow away the dust (from the residents' dandruff, hair, etc.) and bacteria generated by the residents in the activity area, reduce dust accumulation in the activity area, and thereby improve the overall cleanliness of the indoor environment.

[0071] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
