Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
An indoor ventilation detection method, an indoor ventilation detection device and a heating device with the ventilation detection device according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of an indoor ventilation detecting method according to an embodiment of the present invention. As shown in fig. 1, the indoor ventilation detection method according to an embodiment of the present invention may include the following steps:
and S1, collecting the indoor temperature in a preset time period when the heating device is started and starts heating work. The preset time period may be calibrated according to an actual condition, for example, the preset time period may be a value set by a user according to the actual condition, or may be a value preset before the heating apparatus leaves the factory.
According to one embodiment of the invention, the room temperature may be collected by a temperature sensor of the heating appliance. Wherein, the heating equipment can include air conditioner, electric heater and hanging stove.
Specifically, current heating equipment (such as an air conditioner) is provided with a temperature sensor, for example, when the air conditioner is started and starts heating, the air conditioner can collect indoor temperature according to a preset time period by using the built-in temperature sensor, and the cost is saved without additionally adding a sensor.
In addition, due to popularization of the internet of things, the smart home connects various devices (such as an air conditioner, kitchen ventilation equipment, a security system, heating equipment, network household appliances and the like) in the home together through the internet of things technology, has a traditional living function, has functions of building, network communication, information household appliances and equipment automation, and also provides an all-around information interaction function, so that the heating equipment can acquire indoor temperature through temperature sensors on other indoor devices, such as kitchen ventilation equipment, water purification equipment and the like.
And S2, judging whether the indoor temperature in N continuous preset time periods is in a descending state or not, wherein N is a positive integer greater than 1.
And S3, if the indoor temperatures in the N continuous preset time periods are all in a descending state, further judging whether the descending amplitude of the indoor temperatures in the N continuous preset time periods meets the preset amplitude condition.
And S4, if yes, judging that the indoor is in a ventilation state currently.
Specifically, when the ambient temperature is relatively low (e.g., in winter or when the indoor temperature is less than 10 ℃), the heating device may be turned on to supply heat to the user, and after the heating device is turned on, a target temperature, e.g., 22 ℃, may be set, i.e., the indoor temperature is raised to 22 ℃. After a certain period of heating, the indoor temperature is generally near the set target temperature or in an elevated state.
In the process of starting the heating device and starting heating, if the heating device determines that all the indoor temperature values in N consecutive preset time periods (for example, 5 consecutive preset time periods) are in a decreasing state, it is determined whether the decreasing range of the indoor temperature in the N consecutive preset time periods meets a preset range condition, for example, when the temperature decreasing value in the 5 consecutive preset time periods (i.e., the sum of the temperature decreasing values in the 5 consecutive preset time periods) is greater than 5 ℃, it indicates that the indoor is currently in a ventilation state.
For example, during the process of starting the heating device and starting the heating operation, the current indoor temperature is collected once every preset time period to generate the temperature detection curve shown in fig. 2, and the area of the quadrangle formed between the time period and the indoor temperature is calculated. When the indoor temperature is in an increased state, the area of a quadrangle ABCD (right trapezoid) increases with the increase of the sampling period; when the indoor temperature is maintained around the set target temperature, the area of the quadrangle EFGH (rectangle) is basically unchanged; when the indoor temperature is in a falling state, the area of the quadrangle abcd (right trapezoid) decreases as the sampling period increases.
When the indoor temperature is determined to be in a decreasing state (the area of the quadrangle is gradually decreased), if the areas of the quadrangles within 5 consecutive preset time periods are all in a decreasing state, it is determined that the user may open the door for ventilation/open the window for ventilation, and further determined whether the areas of the quadrangles within 5 consecutive preset time periods suddenly decrease, for example, when a decrease value of the area of the quadrangles within 5 consecutive preset time periods (e.g., the sum of the area decrease values from the nth time period to the (n + 4) th time period shown in fig. 2) exceeds 10, it is determined that the indoor temperature is currently in a ventilation state.
In addition, a table (time-temperature) can be generated by using the temperature value detected in each preset time period, for example, when the temperature drop value in the chamber exceeds 5 ℃ in 5 continuous preset time periods, the ventilation state is indicated.
Because the heating equipment is generally a high-power electric appliance, energy conservation is always the focus of attention of users, and after the current indoor ventilation state is judged, the heating equipment can be correspondingly controlled. According to an embodiment of the present invention, after determining that the indoor is currently in the ventilation state, the method further includes: and controlling the heating equipment to stop heating, or controlling the heating equipment to operate in an energy-saving mode.
That is to say, after judging that indoor current is in the ventilation state, automatic control heating installation closes or with energy-conserving mode operation to reach energy-concerving and environment-protective effect, avoided user manual control simultaneously, improved user experience greatly.
It should be noted that, in the embodiment of the present invention, after the indoor is judged to be currently in the ventilation state, the indoor temperature is collected every other preset time period, and if the indoor temperatures in several consecutive preset time periods do not decrease any more (or the indoor temperature decrease values in several consecutive preset time periods do not exceed 2 ℃), and the indoor temperature is greater than the outdoor temperature (10 ℃), it indicates that the user may have closed the door and window, and at this time, the heating device may be automatically controlled to operate according to the set target temperature.
In summary, according to the indoor ventilation detection method provided by the embodiment of the invention, when the heating device is started and starts heating, the indoor temperature is collected in the preset time period, and whether the indoor temperatures in N consecutive preset time periods are all in a falling state is determined, if the indoor temperatures in N consecutive preset time periods are all in a falling state, whether the falling range of the indoor temperatures in N consecutive preset time periods meets the preset range condition is further determined, and if yes, the indoor temperature is currently in a ventilation state is determined. The method not only can effectively detect the indoor ventilation state without increasing the cost, but also can automatically control the heating equipment to stop or operate in an energy-saving mode when the indoor ventilation state is detected, so as to achieve the purpose of saving energy, and meanwhile, a user does not need to manually control the heating equipment to start and stop, thereby greatly improving the user experience.
Fig. 3 is a block schematic diagram of an indoor ventilation detecting apparatus according to an embodiment of the present invention. As shown in fig. 3, the indoor ventilation detecting apparatus according to an embodiment of the present invention may include: the device comprises an acquisition module 10, a first judgment module 20, a second judgment module 30 and a control module 40.
The acquisition module 10 is configured to acquire an indoor temperature at a preset time period when the heating device is started and starts heating. The first determining module 20 is configured to determine whether the indoor temperatures in N consecutive preset time periods are all in a decreasing state, where N is a positive integer greater than 1. The second determining module 30 is configured to determine whether the falling amplitude of the indoor temperature in N consecutive preset time periods meets a preset amplitude condition when the indoor temperature in N consecutive preset time periods is in a falling state. The control module 40 is configured to determine that the room is currently in a ventilation state when the decreasing amplitude of the indoor temperature in N consecutive preset time periods meets a preset amplitude condition.
According to an embodiment of the present invention, the collection module 10 may collect the indoor temperature through a temperature sensor of a heating device, wherein the heating device may include an air conditioner, an electric heater, and a wall-hanging stove.
Specifically, the existing heating devices (such as air conditioners) are equipped with temperature sensors, for example, when the air conditioner is started and starts heating, the acquisition module 10 can acquire the indoor temperature according to a preset time period by using the temperature sensor built in the air conditioner, and no additional sensor is needed, thereby saving the cost.
In addition, due to the popularization of the internet of things, the smart home connects various devices (such as an air conditioner, kitchen ventilation equipment, a security system, heating equipment, network appliances and the like) in the home together through the internet of things technology, so that the smart home has the traditional living function, has the functions of building, network communication, information appliance and equipment automation, and also provides an omnidirectional information interaction function, and the acquisition module 10 can acquire the indoor temperature through temperature sensors on other indoor devices, such as the kitchen ventilation equipment, the water purification equipment and the like.
Specifically, when the ambient temperature is relatively low (e.g., in winter or when the indoor temperature is less than 10 ℃), the heating device may be turned on to supply heat to the user, and after the heating device is turned on, a target temperature, e.g., 22 ℃, may be set, i.e., the indoor temperature is raised to 22 ℃. After a certain period of heating, the indoor temperature is generally near the set target temperature or in an elevated state.
In the process of starting the heating device and starting heating, if the first determining module 20 determines that all the indoor temperature values in N consecutive preset time periods (for example, 5 consecutive preset time periods) are in a decreasing state, and the second determining module 30 determines whether the decreasing range of the indoor temperature in N consecutive preset time periods meets a preset range condition, for example, when the temperature decreasing value in 5 consecutive preset time periods (that is, the sum of the temperature decreasing values in 5 consecutive preset time periods) is greater than 5 ℃, the control module 40 determines that the indoor is currently in a ventilation state.
For example, in the process of starting the heating device and starting heating operation, the collecting module 10 collects the current indoor temperature once every preset time period to generate a temperature detection curve graph as shown in fig. 2, and calculates the area of a quadrangle formed between the time period and the temperature, and when the first judging module 20 judges that the indoor temperature is in a rising state, the area of the quadrangle ABCD (right trapezoid) increases with the increase of the sampling period; when the first judgment module 20 judges that the indoor temperature is maintained around the set target temperature, the area of the quadrangle EFGH (rectangle) is substantially unchanged; when the first judgment module 20 judges that the indoor temperature is in a falling state, the area of the quadrangle abcd (right trapezoid) decreases as the sampling period increases.
When the first determining module 20 determines that the indoor temperature is in a decreasing state (the area of the quadrangle is gradually decreased), if the areas of the quadrangles in 5 consecutive preset time periods are all in a decreasing state, it indicates that the user may open the door for ventilation/open the window for ventilation, the second determining module 30 determines whether the area of the quadrangle in 5 consecutive preset time periods is suddenly decreased, for example, when the second determining module 30 determines that the decrease value of the area of the quadrangle in 5 consecutive preset time periods (e.g., the sum of the area decrease values from the nth time period to the (n + 4) th time period shown in fig. 2) exceeds 10, the control module 40 determines that the quadrangle is currently in a ventilation state.
In addition, it is also possible to generate a table (time-temperature) by using the temperature value detected every time period, for example, when the second determination module 30 determines that the temperature drop value in the chamber exceeds 5 ℃ for 5 consecutive time periods, the control module 40 determines that the ventilation state is currently in.
Because the heating equipment is generally a high-power electric appliance, energy conservation is always the focus of attention of users, and after the current indoor ventilation state is judged, the heating equipment can be correspondingly controlled. According to an embodiment of the present invention, after determining that the room is currently in the ventilation state, the control module 40 is further configured to control the heating device to stop heating, or control the heating device to operate in the energy saving mode.
That is to say, after the control module 40 judges that the room is currently in the ventilation state, the heating device is automatically controlled to be turned off or operated in an energy-saving mode, so that the effects of energy conservation and environmental protection are achieved, meanwhile, manual control of a user is avoided, and the user experience is greatly improved.
It should be noted that, in the embodiment of the present invention, after the control module 40 determines that the room is currently in the ventilation state, the collection module 10 collects the room temperature every other preset time period, and if the room temperature in consecutive time periods does not decrease any more (or the indoor temperature decrease value in consecutive time periods does not exceed 2 ℃), and the room temperature is greater than the outdoor temperature (10 ℃), it indicates that the user may have closed the door and window, and at this time, the control module 40 automatically controls the heating device to operate according to the set target temperature.
It should be noted that, for details not disclosed in the indoor ventilation detecting device according to the embodiment of the present invention, please refer to details disclosed in the indoor ventilation detecting method according to the embodiment of the present invention, which are not described again in detail.
According to the indoor ventilation detection device provided by the embodiment of the invention, when the heating equipment is started and heating work is started, the acquisition module acquires the indoor temperature in a preset time period, the first judgment module judges whether the indoor temperatures in N continuous preset time periods are all in a descending state, if so, the second judgment module judges whether the descending range of the indoor temperatures in N continuous preset time periods meets a preset range condition, and if so, the control module judges that the indoor temperature is in a ventilation state currently. The device not only can effectively detect out indoor ventilation state under the condition of not increasing the cost, can also be detecting out indoor current when being in ventilation state, and automatic control heating installation is shut down or is with energy-conserving mode operation to reach energy-conserving purpose, still need not opening of user manual control heating installation simultaneously and stop, improved user experience greatly.
