FIG. 2 is a flow diagram of a gas detection method in one embodiment. The gas detection method in this embodiment is described by taking the electronic device or the wearable device in fig. 1 as an example. As shown in fig. 2, the gas detection method includes steps 202 to 206.
Step 202: when it is detected that the wearable device is worn at the ear, the concentration of the target gas around the ear is acquired based on an ultrasonic gas detection device built in the wearable device.
In this embodiment, the device is provided with the touch sensor on the wearable equipment, and in the wearable equipment was close to user's duct in-process, the touch sensor can the perception wearable equipment and the degree of proximity of user's duct to judge whether the user wore wearable equipment. It should be understood that the touch sensor is a measurement sensor for determining whether the wearable device is close to the ear canal of the user, and there is no specific quantitative index. In another embodiment, a distance sensor can be further installed on the wearable device, and the distance sensor can accurately measure the distance between the wearable device and the ear canal so as to judge whether the user wears the wearable device.
It should be understood that wearable devices include portable devices such as headsets, bracelets, glasses, and the like.
It should be noted that the touch sensor of the present embodiment can be classified into a laser type, an ultrasonic type, an infrared type, and the like in terms of implementation principle; the working types can be classified into pneumatic type, superconducting type, magnetic induction type, capacitance type, photoelectric type, and the like.
In addition, the wearable device in the present embodiment is also provided with means for gas detection, such as ultrasonic gas detection means. Ultrasonic gas detection devices are sensors that convert an ultrasonic signal into another energy signal (typically an electrical signal) that can emit and receive ultrasonic waves. The ultrasonic wave is a mechanical wave with the vibration frequency higher than 20KHz, and has the characteristics of high frequency, short wavelength, small diffraction phenomenon, good directivity, capability of being directionally propagated as a ray and the like. Specifically, the ultrasonic gas detection device provided in the wearable device in this embodiment can emit ultrasonic waves, and when the ultrasonic waves propagate in a gas medium, the sound velocity of the ultrasonic waves is related to the composition of the gas, that is, the sound velocity changes due to changes in the gas composition, and in addition, even if the gas composition is not changed, the changes in the pressure and the temperature also cause changes in the sound velocity, so that the concentration of the target gas can be obtained by measuring the pressure, the temperature, and the sound velocity of the gas. It should be understood that the concentration of the target gas is the size of the components of the target gas.
Step 204: and judging whether the concentration of the target gas is greater than a preset threshold value.
The wearable device is provided with a preset threshold for storing the concentration of multiple target gases in advance, and the preset threshold can be set according to the type of the target gases. For example, the target gas may be chlorine gas, and when the concentration of chlorine gas reaches a concentration of 5ppm (parts per million), the target gas causes moderate upper respiratory irritation to the human body, and in this case, the preset threshold value of chlorine gas of 5ppm may be set.
Step 206: and when the concentration of the target gas is greater than a preset threshold value, the wearable device executes prompt operation according to the concentration of the target gas.
When the wearable device detects that target gas (the target gas may be harmful gas) exists around the ear and the concentration of the target gas is greater than a preset threshold, the wearable device performs a corresponding prompt operation according to the specific value of the concentration of the target gas. Specifically, the prompt operation may be that the wearable device outputs a voice prompt to the user to inform the user, or reminds the user through a vibration device; the prompt operation can also be sending an early warning signal to the mobile terminal, and informing the user through the screen display of the mobile terminal.
According to the gas detection method, when the wearable device is worn at the ear, the concentration of the target gas around the ear is obtained based on the ultrasonic gas detection device built in the wearable device; judging whether the concentration of the target gas is greater than a preset threshold value or not; when the concentration of the target gas is greater than the preset threshold value, the wearable device executes prompt operation according to the concentration of the target gas, so that the user can know the change condition of the gas components around the user, and the safety of the user is guaranteed.
As shown in fig. 3, in one embodiment, the acquiring of the concentration of the target gas around the ear based on the ultrasonic gas detection device built in the wearable device includes steps 302 to 308.
Step 302: and acquiring the gas to be detected with the preset volume acquired by the ultrasonic gas detection device.
Step 304: and detecting the temperature and the pressure of the gas to be detected.
Step 306: and acquiring the propagation speed of the ultrasonic wave emitted by the ultrasonic gas detection device in the gas to be detected.
Step 308: and determining the concentration of the target gas in the gas to be measured according to the temperature, the pressure and the propagation speed.
In the present embodiment, as shown in fig. 4, fig. 4 provides an ultrasonic gas detection apparatus comprising a transmitting probe 10, a receiving probe 20 and a measurement hole 30. Specifically, the measurement cavity 30 is used for accommodating a predetermined volume of gas to be measured, and is provided with a gas inlet 40 and a gas outlet 50. The gas to be measured around the ear enters the measurement hole 30 through the gas inlet 40 and flows out from the gas outlet 50, so that a predetermined volume of the gas to be measured is stored in the measurement hole 30. It should be understood that the transmitting probe 10 is disposed at one end of the measuring hole 30, the receiving probe 20 is disposed at the other end of the measuring hole 30, and the distance between the transmitting probe 10 and the receiving probe 20 is the length of the measuring hole, and the length is a fixed value. Therefore, the propagation time of the ultrasonic wave in the measurement hole 30 and thus the propagation speed of the ultrasonic wave in the gas to be measured can be determined by detecting the transmission time of the ultrasonic wave transmitted by the transmission probe 10 and the reception time of the ultrasonic wave received by the reception probe 20.
It should be understood that the ultrasonic gas detection device is also provided with a gas temperature sensor and a gas pressure sensor (not shown in fig. 4). The gas temperature sensor is used for detecting the temperature of gas to be detected; the gas pressure sensor is used for detecting the pressure of the gas to be measured (since the measuring hole 30 is communicated with the outside, the pressure is consistent with the gas pressure of the external environment). It should be noted that the gas temperature sensor and the gas pressure sensor may be disposed on the inner wall or both ends of the measurement hole 30, and are not limited herein.
It should be understood that when the temperature, pressure and propagation speed of ultrasonic waves in the gas to be measured are measured, the concentration of the target gas in the gas to be measured can be calculated. Taking the gas to be measured as a binary mixed gas of chlorine and air as an example, when the measured pressure of the gas to be measured is the standard atmospheric pressure P0Temperature of gas to be measured is T0Then, the standard atmospheric pressure P can be obtained0The chlorine constant and the air constant comprise the constant pressure specific heat and the constant volume specific heat of two gases, so that the average constant pressure constant volume heat capacity ratio of chlorine and air is known, namely:
wherein,
the chlorine gas and air mixed gas is a binary mixed gas of chlorine gas and air with average constant pressure, constant volume and heat capacity ratio; n isaIs the chlorine concentration; n isbIs the air concentration; cpaIs the constant pressure specific heat of chlorine; cpbIs the constant pressure specific heat of air; cvaThe specific heat of constant volume of chlorine gas; cvbThe specific heat capacity of air is the constant volume specific heat.
When the temperature and the pressure of the mixed gas are constant, the constant-pressure specific heat and the constant-volume specific heat of the two gases are constant. For example, at a temperature T0Standard atmospheric pressure P0Lower, Cpa0.116Kcal/Kg ℃ (Kcal/Kg ℃, Kcal per kilogram degrees celsius); cva＝0.088Kcal/Kg℃；Cpb＝0.241Kcal/Kg℃；Cva＝0.172Kcal/Kg℃。
In addition, the concentration of the target gas can be further determined according to the measured propagation speed of the ultrasonic wave in the gas to be measured. Namely:
wherein,
is the average constant pressure and constant volume heat of binary mixed gas of chlorine and airA capacity ratio;
the average molecular weight of binary mixed gas of chlorine and air;
the propagation speed of the ultrasonic wave in the binary mixed gas of chlorine and air is adopted; r is a universal gas constant; t is the absolute temperature of the binary mixed gas of chlorine and air. Understandably, when determining
When the temperature of the water is higher than the set temperature,
is a constant.
It should be understood that as a matter of understanding,
the values of (d) are related to the chlorine concentration and the air concentration, i.e.:
wherein n isaIs the chlorine concentration; n isbIs the air concentration; maIs the molecular weight of chlorine; mbIs the molecular weight of air.
In addition, in the binary mixed gas of chlorine gas and air, the following relationship is satisfied: n isa+nb＝1。
In summary, the relationship that the chlorine concentration satisfies can be obtained:
it should be noted that, in the following description,
t is the propagation speed of the ultrasonic wave in the binary mixed gas of the chlorine and the air, and the absolute temperature of the binary mixed gas of the chlorine and the air.
And T can be measured by an ultrasonic gas detector when measured
T and the pressure P of the binary mixed gas of chlorine and air, C in the above formulapa、Cpb、CvaAnd CvbIs a known constant. Therefore, the chlorine gas concentration n can be determined from the above-mentioned relational expression satisfied by the chlorine gas concentrationaThe value of (c).
It should be noted that, in other embodiments, the gas not to be measured may also be a mixed gas of other gases (toxic gases) and air, and is not limited herein. However, when the temperature, the pressure and the propagation velocity of the ultrasonic wave in the gas to be measured are measured, the concentration of the target gas in the gas to be measured can be determined, and the specific determination method refers to the measurement of the chlorine concentration and is not described herein again.
As shown in fig. 5, in one embodiment, acquiring the propagation velocity of the ultrasonic wave emitted by the ultrasonic gas detection device in the gas to be detected includes steps 502 to 506.
Step 502: and acquiring a preset path of the ultrasonic wave transmitted in the gas to be detected.
Step 504: and detecting the propagation time of the ultrasonic wave propagating in the gas to be detected.
Step 506: and calculating the propagation speed according to the preset distance and the propagation time.
In this embodiment, referring to fig. 4, the predetermined distance is the length of the measurement hole 30, and may be referred to as the acoustic path L of the ultrasonic wave. The ultrasonic wave is emitted from the transmitting probe 10, and is received by the receiving probe 20 after propagating a fixed acoustic path L in the measurement cavity 30 through the medium of the gas to be measured. The propagation time t of the ultrasonic wave in the measurement hole 30 (i.e. the propagation time of the ultrasonic wave propagating a fixed sound path L in the gas to be measured) can be determined according to the transmitting time of the transmitting probe 10 and the receiving time of the receiving probe 20; according to the fixed acoustic path L (i.e. the preset path) and the propagation time t, the propagation speed of the ultrasonic wave in the gas to be measured can be calculated, that is:
wherein,
the propagation speed of the ultrasonic wave in the gas to be detected is adopted; l is the sound path; t propagation time of ultrasonic wave in the gas to be measured.
As shown in fig. 6, in one embodiment, determining the concentration of the target gas in the gas to be measured according to the temperature, the pressure and the propagation velocity further includes steps 602 to 606.
Step 602: the correspondence between the propagation speed of the ultrasonic wave in the preset mixed gas and the concentration of the target gas is stored in advance.
The preset mixed gas comprises a binary mixed gas of chlorine and air, or a binary mixed gas of other target gas and air, or a multi-element mixed gas of other gases and air. Taking a binary mixed gas of chlorine and air as an example, when the temperature and the pressure of the mixed gas are constant, the propagation speed of the ultrasonic wave in the mixed gas has a one-to-one correspondence relationship with the concentration of the chlorine, and the correspondence relationship is shown in fig. 7. Therefore, the corresponding relation between the chlorine concentration and the propagation speed of the ultrasonic wave in the mixed gas at different temperatures under a certain pressure can be stored in advance.
Step 604: and when the temperature and the pressure of the gas to be measured are consistent with the preset mixed gas, acquiring the propagation speed of the ultrasonic wave in the gas to be measured.
When the temperature and the pressure of the gas to be detected are detected to be consistent with those of the preset mixed gas, the corresponding relation between the propagation speed of the gas to be detected and the preset mixed gas and the concentration of the target gas can be judged to be the same.
Step 606: and acquiring the corresponding concentration of the target gas from the corresponding relation between the propagation speed in the preset mixed gas and the concentration of the target gas according to the propagation speed.
When the temperature and the pressure of the gas to be detected are detected to be consistent with those of the preset mixed gas, the concentration of the target gas corresponding to the propagation speed of the ultrasonic wave in the gas to be detected is obtained according to the corresponding relation between the propagation speed in the preset mixed gas and the concentration of the target gas.
In this embodiment, it should be noted that the ultrasonic gas detection device also stores the above correspondence of other mixed gases, and the correspondence is not listed here.
As shown in fig. 8, in one embodiment, when the concentration of the target gas is greater than the preset threshold, the wearable device performs a prompt operation according to the concentration of the target gas, including steps 802 to 804.
Step 802: when the concentration of the target gas is larger than a preset threshold value, the wearable device determines the warning level according to the concentration of the target gas.
Step 804: and executing corresponding prompt operation according to the warning level.
The wearable device defines concentration ranges of the target gases in advance, sets corresponding warning levels for the concentration ranges of the target gases, and stores the concentration ranges of the target gases and the warning levels corresponding to the concentration ranges of the target gases in the corresponding relation between the concentration ranges of the target gases and the warning levels. For example, the target gas is chlorine gas, and four chlorine gas concentration ranges are defined in advance, which are 3ppm to 9ppm, 9ppm to 18ppm, 18ppm to 90ppm, and more than 90ppm, respectively. And presetting warning levels corresponding to the chlorine concentration ranges, namely a first level, a second level, a third level and a fourth level. Different warning levels represent the injury degree to the human body, and corresponding prompt operation can be executed according to the warning levels. For example, the user may be prompted for a specific length of time to contact the gas based on the warning level, for 30 minutes when the warning level is a first level, and for immediate removal from the gas when the warning level is a fourth level.
The mapping relationship between the concentration of the target gas and the warning level is set according to the type of the target gas, and is not limited to the above example.
As shown in fig. 9, in one embodiment, the prompting operation includes playing an alert voice, and executing a corresponding prompting operation according to an alert level, including steps 902 to 904.
Step 902: and acquiring a prestored volume value corresponding to the warning level.
Step 904: and playing warning voice for the user according to the prestored volume value.
The wearable device in this embodiment is provided with an alarm. The description will be made by taking the electronic device or the wearable device in fig. 1 as an example. The electronic equipment comprises a memory and a processor, wherein the memory stores prestored sound volumes corresponding to a plurality of warning levels.
