Referring now to fig. 1, fig. 1 is a schematic block diagram of an in-vehicle air quality monitoring system 100 in accordance with an embodiment of the present invention. The in-vehicle air quality monitoring system 100 includes an air quality detection module 110, a control signal generation module 120, and a control module 130.
The air quality detection module 110 is configured to obtain one or more in-vehicle air quality parameter values representing an in-vehicle air quality and one or more out-of-vehicle air quality parameter values representing an out-of-vehicle air quality. Wherein the air quality detection module 110 may include an off-board PM2.5 sensor and an on-board PM2.5 sensor. Optionally, the air quality detection module 110 may also include an off-board PM (inhalable particulate matter) 10 sensor and an on-board PM10 sensor. In one embodiment, the air quality detection module 110 may also include an in-vehicle and/or out-of-vehicle carbon dioxide sensor. Accordingly, the in-vehicle air quality parameter values may include one or more of an in-vehicle PM2.5 value, an in-vehicle PM10 value, and an in-vehicle carbon dioxide value, among others. The off-board air quality parameter values may include one or more of an off-board PM2.5 value, an off-board PM10 value, and an off-board carbon dioxide value, among others. Therefore, the system can timely know the condition of poor air quality or the condition of high carbon dioxide concentration in the vehicle and adopt a purification or ventilation measure.
The control signal generation module 120 is configured to generate control signals for initiating respective multi-stage air purification operations based on the one or more in-vehicle air quality parameter values and the one or more out-of-vehicle air quality parameter values from the air quality detection module. In one embodiment, taking the example that the air quality parameter value represents the inhalable particulate matter concentration, the control signal for initiating the primary air purification operation is generated when the in-vehicle air quality parameter value is between the first threshold value and the third threshold value; generating a control signal for starting secondary air purification operation when the value of the air quality parameter in the vehicle is between a third threshold value and a fifth threshold value; and generating a control signal for starting the three-stage air purification operation when the value of the air quality parameter in the vehicle is larger than a fifth threshold value. Wherein the first threshold, the third threshold and the fifth threshold are increased in sequence. Specifically, the first threshold may be 50 μ g/m3The third threshold may be 75 μ g/m3And the fifth threshold may be 85 μ g/m3. Therefore, under the condition of different air pollution degrees in the vehicle, targeted purification operation can be correspondingly adopted so as to efficiently realize the purpose of quickly purifying the air in the vehicle.
The control module 130 is configured to control a device corresponding to the control signal in response to the control signal from the control signal generation module 120. The device comprises one or more of a fan, an internal and external circulation control device, a negative ion generator and a vehicle window. Although only the above devices for purifying and refreshing air in a vehicle are listed here, any device capable of achieving the object as proposed in the present invention is usable.
Specifically, in one implementation, control signals that control the apparatus for multi-stage air purification may be generated as described below. The control signal generating module 120 is configured to generate a control signal for controlling the fan to lift the air volume and controlling the internal and external circulation control device to switch to the external circulation if the detected external air quality parameter value is less than the second threshold value during the primary air purification operation; and if the detected value of the air quality parameter outside the vehicle is larger than the second threshold value, generating a control signal for controlling the lifting air quantity of the fan and controlling the internal and external circulation control device to be switched into the internal circulation. Wherein the second threshold is smaller than the first threshold, for example, the second threshold may be 40 μ g/m3. By reasonably setting the second threshold value, only internal circulation is performed without external circulation under the condition that the air quality outside the automobile is not obviously superior to the air quality inside the automobile, so that pollutants such as inhalable particles and the like outside the automobile are prevented from being introduced into the automobile, and the air purification efficiency inside the automobile is prevented from being reduced. During the primary air cleaning operation, the window is maintained in a closed state.
The control signal generation module 120 is further configured to, during the secondary air purification operation, if the off-board air quality parameter value is detected to be less than a fourth threshold value (e.g., 60 μ g/m) 3) And if the ambient temperature outside the vehicle represented by the temperature value outside the vehicle is proper, a control signal for controlling the fan to lift the air quantity and controlling the opening of the vehicle window is generated. Therein, the off-board temperature value is obtained by a temperature detection module 140, which is typically a temperature sensor and may also be used to obtain an in-vehicle temperature value representing an in-vehicle temperature. When the window is opened, because strong inside and outside convection is formed, the inside and outside air of the vehicle can be effectively exchanged, the inside air of the vehicle can be updated more quickly, and the use of the inside circulation or the outside circulation is not needed to be considered. And if the detected value of the air quality parameter outside the automobile is larger than the fourth threshold value, generating a control signal for controlling the closing of the automobile window, controlling the lifting air quantity of the fan and controlling the switching of the internal and external circulation control device to the internal circulation.
The control signal generation module 120 is further configured to turn on the anion generator to generate a control signal for controlling the turning on of the anion generator and the switching of the internal and external circulation control device to the internal circulation state during the three-stage air purification operation. In this case, since the degree of pollution in the vehicle is already high, the negative ion generator is turned on to generate negative ions to absorb pollutants and harmful gases in the air. The anion generator can generate anions to adsorb smoke, dust and other small particles in the air, and the purification effect is far greater than the operation of filtration or physical adsorption, so that the aim of quickly purifying the air in the vehicle is fulfilled.
In further implementations, the control signal generation module 120 may be configured to first only compare the in-vehicle air quality parameter value with a first threshold value, generate a control signal to initiate a primary air purification operation and generate a control signal for a corresponding device as long as the in-vehicle air quality parameter value is greater than the first threshold value; otherwise, the current state is maintained. When the primary air purification operation is executed for a first time threshold, the control signal generation module 120 compares the in-vehicle air quality parameter value with a third threshold, and if the in-vehicle air quality parameter value is greater than the third threshold, generates a control signal for starting the secondary air purification operation and generates a control signal of a corresponding device; otherwise, the current state is maintained. When the secondary air purification operation is performed for a second time threshold, the control signal generation module 120 compares the in-vehicle air quality parameter value with a fifth threshold, and if the in-vehicle air quality parameter value is greater than the fifth threshold, generates a control signal for starting the tertiary air purification operation and generates a control signal for a corresponding device; otherwise, the current state is maintained.
In another embodiment, the in-vehicle air quality parameter value further includes a carbon dioxide concentration value. In this embodiment, the control signal generation module 120 is further configured to generate a control signal for controlling the window to be opened and/or a control signal for controlling the inner and outer circulation control device to switch to the outer circulation state when the carbon dioxide concentration value is higher than the carbon dioxide concentration threshold value. Generally, when the carbon dioxide concentration value is higher than the carbon dioxide concentration threshold value, the internal and external circulation control device is first controlled to switch to the external circulation state. When the external circulation still can not reach the expected carbon dioxide concentration after a period of time, a control signal for controlling the opening of the vehicle window can be generated. Therefore, the air outside the vehicle can be used for rapidly supplementing the oxygen inside the vehicle and reducing the carbon dioxide content inside the vehicle. The air quality in the vehicle can be actively improved well under the conditions of more people in the vehicle and poorer air circulation, and the comfort and the safety of passengers are improved.
However, when both air purification (due to too high a concentration of inhalable particles) and carbon dioxide reduction (due to too many occupants in the vehicle and/or too long an in-vehicle cycle time) are required, a conflict between the in-out cycle demand and the window opening and closing demand may occur, at which point the control signal generation module 120 may be configured to selectively prioritize the generation of control signals for air purification or carbon dioxide reduction as needed.
The in-vehicle air quality monitoring system 100 may further include a display module 150 (not shown in fig. 1), which may be used to display an in-vehicle air quality notification signal and an in-vehicle air quality alarm signal. The in-vehicle air quality notification signal may be set to be displayed on the display module 150 when the in-vehicle air quality needs to be adjusted, or may be set to be displayed on the display module 150 in a normal case. The in-vehicle air quality alarm signal may be set to be displayed on the display module 150 in a more striking manner to remind the in-vehicle personnel when the in-vehicle air quality satisfies a certain threshold condition.
In addition, the in-vehicle air quality monitoring system 100 may further include a speaker 160 (not shown in fig. 1) for alerting the on-vehicle occupant synchronously or asynchronously with the in-vehicle air quality alarm signal.
Turning now to fig. 2, fig. 2 is a schematic flow diagram of an in-vehicle air quality monitoring method 200 in accordance with an embodiment of the present invention.
The in-vehicle air quality monitoring method 200 includes a step 210 of obtaining one or more in-vehicle air quality parameter values indicative of an in-vehicle air quality and one or more out-vehicle air quality parameter values indicative of an out-vehicle air quality in the step 210. Where off-board PM2.5 data and in-board PM2.5 data may be acquired. Alternatively, off-board PM (inhalable particulate matter) 10 data and on-board PM10 data may also be acquired. In one embodiment, in-vehicle and/or off-vehicle carbon dioxide data may also be obtained. Therefore, the system can timely know the condition of poor air quality or the condition of high carbon dioxide concentration in the vehicle and adopt a purification or ventilation measure.
In step 220, control signals for initiating respective multi-stage air purification operations are generated based on the one or more in-vehicle air quality parameter values and the one or more out-of-vehicle air quality parameter values from the air quality detection module. In one embodiment, taking the example that the air quality parameter value represents the inhalable particulate matter concentration, the control signal for initiating the primary air purification operation is generated when the in-vehicle air quality parameter value is between the first threshold value and the third threshold value; generating a control signal for starting secondary air purification operation when the value of the air quality parameter in the vehicle is between a third threshold value and a fifth threshold value; and generating a control signal for starting the three-stage air purification operation when the value of the air quality parameter in the vehicle is larger than a fifth threshold value. Wherein the first threshold, the third threshold and the fifth threshold are increased in sequence. Specifically, the first threshold may be 50 μ g/m 3The third threshold may be 75 μ g/m3And the fifth threshold may be 85 μ g/m3. Therefore, under the condition of different air pollution degrees in the vehicle, targeted purification operation can be correspondingly adopted so as to efficiently realize the purpose of quickly purifying the air in the vehicle.
In step 230, a device corresponding to the control signal is controlled in response to the control signal. The device comprises one or more of a fan, an internal and external circulation control device, a negative ion generator and a vehicle window. Although only the above devices for purifying and refreshing air in a vehicle are listed here, any device capable of achieving the object as proposed in the present invention is usable.
Specifically, in one implementation, control signals that control the apparatus for multi-stage air purification may be generated as described below. In the process of primary air purification operation, if the detected outside air quality parameter value is smaller than a second threshold value, generating a control signal for controlling the lifting air quantity of the fan and controlling the switching of the inside and outside circulation control device to the outside circulation; if the quality of air outside the vehicle is detectedAnd if the numerical value is larger than the second threshold value, generating a control signal for controlling the lifting air quantity of the fan and controlling the internal and external circulation control device to be switched into the internal circulation. Wherein the second threshold is smaller than the first threshold, for example, the second threshold may be 40 μ g/m 3. By reasonably setting the second threshold value, only internal circulation is performed without external circulation under the condition that the air quality outside the automobile is not obviously superior to the air quality inside the automobile, so that pollutants such as inhalable particles and the like outside the automobile are prevented from being introduced into the automobile, and the air purification efficiency inside the automobile is prevented from being reduced. During the primary air cleaning operation, the window is maintained in a closed state.
During the secondary air purification operation, if it is detected that the value of the air quality parameter outside the vehicle is less than a fourth threshold value (e.g., 60 μ g/m)3) And if the ambient temperature outside the vehicle represented by the temperature value outside the vehicle is proper, a control signal for controlling the fan to lift the air quantity and controlling the opening of the vehicle window is generated. Wherein the temperature detection module 140 is used to obtain an outside temperature value, the temperature detection module 140 is typically a temperature sensor and may also be used to obtain an inside temperature value representing an inside temperature. When the window is opened, because strong inside and outside convection is formed, the inside and outside air of the vehicle can be effectively exchanged, the inside air of the vehicle can be updated more quickly, and the use of the inside circulation or the outside circulation is not needed to be considered. And if the detected value of the air quality parameter outside the automobile is larger than the fourth threshold value, generating a control signal for controlling the closing of the automobile window, controlling the lifting air quantity of the fan and controlling the switching of the internal and external circulation control device to the internal circulation.
And in the process of three-stage air purification operation, the anion generator is started to generate a control signal for controlling the start of the anion generator and the switching of the internal and external circulation control device to the internal circulation state. In this case, since the degree of pollution in the vehicle is already high, the negative ion generator is turned on to generate negative ions to absorb pollutants and harmful gases in the air. The anion generator can generate anions to adsorb smoke, dust and other small particles in the air, and the purification effect is far greater than the operation of filtration or physical adsorption, so that the aim of quickly purifying the air in the vehicle is fulfilled.
In a further implementation, first only the in-vehicle air quality parameter value is compared with a first threshold value, and as long as the in-vehicle air quality parameter value is greater than the first threshold value, a control signal to initiate a primary air purification operation is generated and a control signal for the corresponding device is generated; otherwise, the current state is maintained. When the first-stage air purification operation is executed to reach a first time threshold value, comparing an in-vehicle air quality parameter value with a third threshold value, and if the in-vehicle air quality parameter value is greater than the third threshold value, generating a control signal for starting the second-stage air purification operation and generating a control signal of a corresponding device; otherwise, the current state is maintained. When the secondary air purification operation is executed for a second time threshold, comparing the value of the in-vehicle air quality parameter with a fifth threshold, and if the value of the in-vehicle air quality parameter is greater than the fifth threshold, generating a control signal for starting the tertiary air purification operation and generating a control signal of a corresponding device; otherwise, the current state is maintained.
In another embodiment, the in-vehicle air quality parameter value further includes a carbon dioxide concentration value. In this embodiment, when the carbon dioxide concentration value is higher than the carbon dioxide concentration threshold value, a control signal for controlling the opening of the vehicle window and/or a control signal for controlling the internal and external circulation control device to switch to the external circulation state are/is generated. Generally, when the carbon dioxide concentration value is higher than the carbon dioxide concentration threshold value, the internal and external circulation control device is first controlled to switch to the external circulation state. When the external circulation still can not reach the expected carbon dioxide concentration after a period of time, a control signal for controlling the opening of the vehicle window can be generated. Therefore, the air outside the vehicle can be used for rapidly supplementing the oxygen inside the vehicle and reducing the carbon dioxide content inside the vehicle. The air quality in the vehicle can be actively improved well under the conditions of more people in the vehicle and poorer air circulation, and the comfort and the safety of passengers are improved.
However, when both a purification of the air (due to too high a concentration of inhalable particles) and a reduction of the carbon dioxide concentration (due to too many occupants in the vehicle and/or too long a cycle time in the vehicle) are required, a conflict between the demand for internal and external circulation and the demand for opening and closing the windows may occur, at which time the priority of purifying the air or reducing the carbon dioxide concentration may be selectively set as required.
The method 200 may further include displaying the in-vehicle air quality notification signal and the in-vehicle air quality alarm signal using a display module. The in-vehicle air quality notification signal may be set to be displayed when the in-vehicle air quality needs to be adjusted, or may be set to be displayed in a normal state. The in-vehicle air quality alarm signal can be set to be displayed in a more striking manner to remind people on the vehicle when the in-vehicle air quality meets a certain threshold condition. The method 200 may also include using a speaker for alerting occupants of the vehicle synchronously or asynchronously with the in-vehicle air quality alarm signal.
According to a third aspect of the invention, a vehicle is provided comprising an in-vehicle air quality monitoring system according to the invention. The vehicle can automatically and quickly purify and/or improve air in the vehicle, and improves the comfort and safety of passengers.
