The present disclosure generally relates to terminals and, more particularly, to a smart respirator and a method and device for calculating pollutant absorption.
With the development of science and technology, the pollution caused by industrial production is getting worse. The density of pollutant, such as Fine Particulate Matter (PM 2.5) or the like, in the air is increasing year by year, and people are more likely to suffer from various kinds of respiratory diseases. Since a respirator can filter the air entering the lung of a user to some extent, it can prevent the pollutant in the air, such as poisonous gas or dust, from entering into the lung. Therefore, respirators have become an important defense for people's health.
In accordance with the present disclosure, there is provided a smart respirator including a main respirator-body having a first open end and a second open end. A diameter of the first open end is smaller than a diameter of the second open end. The smart respirator further includes a front respirator-body arranged at the first open end. The front respirator-body includes a filter sheet arranged inside the front respirator-body and configured to absorb pollutants in air entering the front respirator-body, an air sensor arranged inside the front respirator-body and configured to detect an air index of filtered air filtered by the filter sheet, and a flow sensor arranged inside the front respirator-body and configured to determine a total respiratory amount. The smart respirator also includes a fixation band arranged at the second open end.
Also in accordance with the present disclosure, there is provided a method for calculating a pollutant absorption quantity. The method includes detecting an air index of filtered air when a user is wearing a smart respirator, determining a total respiratory amount of the user, and sending the air index of the filtered air and the total respiratory amount to a terminal.
Also in accordance with the present disclosure, there is provided a method for calculating a pollutant absorption quantity. The method includes receiving an air index of filtered air and a total respiration amount sent by a smart respirator, acquiring a local air index, and calculating the pollutant absorption quantity according to the air index of the filtered air, the total respiratory amount, and the local air index.
It is to be understood that both the forgoing general description and the following detailed description are exemplary only, and are not restrictive of the present disclosure.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the invention and, together with the description, serve to explain the principles of the invention.
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the invention. Instead, they are merely examples of devices and methods consistent with aspects related to the invention as recited in the appended claims.
The fixation band 103 is configured to fix the smart respirator 100 on the user's mouth and nose at the second open end 1022, so that a closed cavum is formed between the main respirator-body 102 and the user's mouse and nose.
With the filter sheets 1011 and the sensors 1012 arranged in turn inside the front respirator-body 101, the smart respirator 100 can detect the air index of the filtered air and determine the user's total respiratory amount when the user is wearing the smart respirator 100.
Exemplary methods consistent with the present disclosure will be described below with respect to
In some embodiments, before the air index of the filtered air and the total respiratory amount are sent to the terminal, a Bluetooth function of the smart respirator is enabled to connect to the terminal via Bluetooth signals. Alternatively, an NFC function of the smart respirator is enabled to connect to the terminal via an NFC data channel. Alternatively, an infrared function of the smart respirator is enabled to connect to the terminal via infrared signals.
In some embodiments, the alternative technical solutions described above can be combined, and the details of the combination are omitted here.
In some embodiments, before receiving the air index of the filtered air and the total respiratory amount sent by the smart respirator, the terminal can enable a Bluetooth function to connect to the smart respirator via Bluetooth signals, enable an NFC function to connect to the smart respirator via an NFC data channel, or enable an infrared function to connect to the smart respirator via infrared signals.
In some embodiments, the terminal can acquire the local air index via the Internet or by a built-in air sensor.
In some embodiments, to calculate the pollutant absorption quantity, the terminal can calculate an air purification degree according to the local air index and the air index of the filtered air, and calculate the pollutant absorption quantity according to the total respiratory amount and the air purification degree.
In some embodiments, after calculating the pollutant absorption quantity, the terminal can upload the pollutant quantity to a server, which determines an absorption-quantity ranking according to the pollutant absorption quantities uploaded by various terminals and returns the absorption-quantity ranking to the terminals. The terminal can then receive the absorption-quantity ranking sent by the server.
All the above alternative technical solutions can be combined as needed to form alternative embodiments of the disclosure, which are not elaborated here.
At 502, the smart respirator determines the total respiratory amount of the user, for example, by the flow sensor arranged in the smart respirator.
In some embodiments, the smart respirator detects the air index of the filtered air and determines the total respiratory amount simultaneously.
At 503, the smart respirator sends the air index of the filtered air and the total respiratory amount to the terminal. In some embodiments, a connecting module is arranged inside a processor of the smart respirator. The connecting module can be a Bluetooth module, an NFC module, an infrared module, or the like, and is used to establish a connection with the terminal, which also has a connecting function. For example, the smart respirator and the terminal enable the Bluetooth function, and discover each other in a process of device discovery. The smart respirator broadcasts a Bluetooth signal. After the terminal receives the Bluetooth signal broadcast by the smart respirator, a connection is established between the terminal and the smart respirator according to the received Bluetooth signal. As another example, the smart respirator and the terminal enable the NFC function, and an NFC channel is established by exchanging packets. Thus, the connection between the smart respirator and the terminal is established by the established NFC channel. As a further example, the smart respirator and the terminal enable the infrared function, and discover each other in a process of device discovery. The smart respirator broadcasts an infrared signal. The terminal receives the infrared signal broadcast by the smart respirator, and a connection is established between the terminal and the smart respirator according to the received infrared signal.
At 504, after receiving the air index of the filtered air and the total respiratory amount sent by the smart respirator, the terminal acquires a local air index. The air index refers to the density of fine particulate matter, sulfur dioxide, nitrogen dioxide, ozone, carbon monoxide, or the like, and is measured by microgram per stere. In some embodiments, after receiving the air index of the filtered air and the total respiratory amount sent by the smart respirator, the terminal can determine the position of the terminal via a Global Positioning System (GPS), and acquire the local air index from the Internet. The terminal can also retrieve data issued by a local observatory to acquire the local air index. The terminal can also detect the local air index over time by a built-in air sensor, store the detected air index in a database, and retrieve the local air index from the database when receiving a wearing time sent by the smart respirator.
At 505, the terminal calculates the pollutant absorption quantity according to the air index of the filtered air, the total respiratory amount, and the local air index. In some embodiments, the terminal first calculates an air purification degree according to the local air index and the air index of the filtered air. Specifically, the terminal can subtract the air index of the filtered air from the local air index to get the air purification degree, i.e., air purification degree (mg/m3)=local air index (mg/m3)−air index of the filtered air (mg/m3). For example, if the local air index when the user wears the smart respirator is 20 mg/m3, and the air index of the filtered air is 8 mg/m3, then the degree of purification of the air=the local air index−the air index of the filtered air=(20-8) mg/m3=12 mg/m3.
Then, the terminal calculates the pollutant absorption quantity according to the total respiratory amount and the air purification degree. Specifically, the terminal can multiply the degree of purification of the air by the total respiratory amount to get the pollutant absorption quantity, i.e., pollutant absorption quantity (mg)=air purification degree (mg/m3)×total respiratory amount (m3)=(local air index−air index of the filtered air)×total respiratory amount. For example, if the local air index when the user wears the smart respirator is 35 mg/m3, the air index of the filtered air of the air filtered by the smart respirator is 15 mg/m3, and the total respiratory amount when the user is wearing the smart respirator is 10 m3, then the pollutant absorption quantity=(the local air index—the air index of the filtered air)×the total respiratory capacity=(35 mg/m3−15 mg/m3)×10 m3=200 mg.
In some embodiments, the terminal uploads the calculated pollutant absorption quantity to a server, which determines an absorption-quantity ranking according to the pollutant absorption quantities uploaded by various terminals and returns the absorption-quantity ranking to the terminal. The terminal shows the absorption-quantity ranking to the user after having received the ranking from the server so that the user can more directly appreciate the performance of the smart respirator and the status of the local air quality.
In some embodiments, the smart respirator 600 further includes a connecting module configured to enable a Bluetooth function to connect to the terminal via Bluetooth signals, to enable an NFC function to connect to the terminal via an NFC data channel, or to enable an infrared function to connect to the terminal via infrared signals.
In some embodiments, the device 700 further includes a connecting module (not shown) configured to enable a Bluetooth function to connect to the smart respirator via Bluetooth signals, to enable an NFC function to connect to the smart respirator via a NFC data channel, or to enable an infrared function to connect to the smart respirator via infrared signals.
In some embodiments, the acquiring module 702 is configured to acquire the local air index via the Internet or by a built-in air sensor.
In some embodiments, the calculating module 703 is configured to calculate an air purification degree according to the local air index and the air index of the filtered air, and calculate the pollutant absorption quantity according to the total respiratory amount and the air purification degree.
In some embodiments, the device 700 further includes an uploading module (not shown) and a second receiving module (not shown). The uploading module is configured to upload the pollutant quantity to a server, which determines an absorption-quantity ranking according to pollutant absorption quantities uploaded by various terminals and returns the ranking of the absorption. The second receiving module is configured to receive the absorption-quantity ranking sent by the server.
