At present, exhaled breath alcohol detectors are mainly used for alcohol detection of users, but exhaled breath alcohol detectors mainly use air pressure to detect human exhalation pressure to control the switch, or use an air pump. If there is a certain alcohol concentration in the environment, it will affect the test results of the breath alcohol detector. However, the traditional breath alcohol detector does not consider the alcohol concentration in the environment, so the alcohol concentration detection in the breath is inaccurate. In addition, in order to facilitate the user to perform alcohol detection, an electrochemical sensor is used to detect the alcohol concentration in the exhaled breath. If there is a certain alcohol concentration in the environment, the alcohol concentration in the environment will not only affect the detection of the alcohol concentration in the exhaled breath. As a result, the long-term use of the electrochemical sensor in an environment containing alcohol will also affect the service life.

FIG. 1 is an optional flowchart of the alcohol concentration detection method provided by the embodiment of the present application. The method in FIG. 1 may include, but is not limited to, steps S101 to S107.

Step S101, obtaining the current time.

Step S102, screening out the detection period from the preset period matching information according to the current time; wherein, the period matching information stores the matching information of the time interval and the detection period.

In step S103, the alcohol concentration of the current environment is detected according to the detection period to obtain the environmental alcohol concentration.

Step S104, compare the ambient alcohol concentration with a preset concentration threshold to obtain an ambient alcohol detection result.

Step S105, acquiring the initial alcohol concentration of the user's breath.

In step S106, data adjustment is performed on the initial alcohol concentration according to the environmental alcohol detection result and the environmental alcohol concentration to obtain the target alcohol concentration.

Step S107, generating target display information according to the environmental alcohol detection result and the target alcohol concentration.

Steps S101 to S107 shown in the embodiment of the present application, the environmental alcohol concentration is obtained by first screening out the detection period from the preset period matching information according to the current time, and then detecting the alcohol concentration of the current environment according to the detection period. By determining the corresponding detection period according to the current time, different detection periods can be adopted according to different time periods, and there is no need to maintain a high-frequency detection period at all times, so as to save energy consumption. Then compare the ambient alcohol concentration with the preset concentration threshold to obtain the ambient alcohol detection result, and adjust the data of the initial alcohol concentration according to the ambient alcohol detection result and the ambient alcohol concentration, so as to correct the initial alcohol concentration according to the ambient alcohol detection result to obtain The target alcohol concentration improves the accuracy of the user's breath alcohol concentration detection. At the same time, the target display information is generated according to the environmental alcohol detection result and the target alcohol concentration, so that the user can know the target alcohol concentration according to the target display information and understand the environmental alcohol detection. As a result, it is convenient to take corresponding protective measures according to the target display information, thereby reducing the influence of the electrochemical sensor on the alcohol in the environment.

In step S101 of some embodiments, the current time is obtained, and if the alcohol concentration detection method is applied to the wearable device, the current time on the wearable device is directly obtained. The current time on the wearable device is the system time of the wearable device at the current moment.

In step S102 of some embodiments, the period matching information stores matching information between a time interval and a detection period, and the corresponding detection period is determined by judging in which time interval the current time is located. Since the user needs to detect the alcohol concentration of the exhaled breath in different time intervals, the detection frequency needs to be different for different time intervals. In high places, different detection cycles are adopted according to different time intervals, and there is no need to detect the alcohol concentration of the current environment in real time in one cycle throughout the day, so as to save the energy consumption of the equipment. Among them, the environment in which the wearable device is located: on the one hand, because it is worn on the user's hand, the user is the wearable device's environment for the wearable device; on the other hand, the wearable device is not worn on the user's hand. The environment in which the user is located, and the environment in which the user + device is located.

In step S103 of some embodiments, after the detection period is determined, the alcohol concentration of the current environment is detected according to the detection period to obtain the environmental alcohol concentration. The current environment is the environment in which the wearable device is located. Collect a plurality of ambient alcohol concentrations according to the detection period, set a preset number of ambient alcohol concentrations as one group, and then calculate the average value of the ambient alcohol concentrations in a group to obtain the ambient alcohol concentration value. For example, if the detection period is 10 minutes to detect a group, the detection time of each group is 1 second, and one group detects 3 ambient alcohol concentrations, the average of the three ambient alcohol concentrations is the currently detected ambient alcohol concentration.

In step S104 of some embodiments, the ambient alcohol concentration is compared with a preset concentration threshold to determine whether the currently detected ambient alcohol concentration is greater than the preset concentration threshold, and an ambient alcohol detection result is obtained. Wherein, the preset concentration threshold is determined according to the detection result of the alcohol concentration that will affect the exhaled gas.

In step S105 of some embodiments, the initial alcohol concentration is obtained by performing alcohol concentration detection on the gas exhaled by the user through an electrochemical sensor. Among them, if there is a certain alcohol concentration in the current environment, and the detection of the gas alcohol concentration in the user's breath is affected, the initial alcohol concentration is affected by the environmental alcohol concentration. If the alcohol concentration in the current environment does not affect the gas alcohol concentration detection, the initial alcohol concentration is not affected by the environmental alcohol concentration.

In step S106 of some embodiments, it is determined whether the environmental alcohol concentration has an influence on the initial alcohol concentration according to the environmental alcohol detection result, and then data adjustment is performed on the initial alcohol concentration according to the environmental detection result and the environmental alcohol concentration to obtain the target alcohol concentration. By adjusting the initial alcohol concentration with the influence of environmental alcohol concentration, the accuracy of alcohol concentration detection in exhaled gas can be improved.

In step S107 of some embodiments, the target alcohol concentration is obtained by calibrating the initial alcohol concentration, and then the target display information is generated according to the target alcohol concentration and the environmental alcohol detection result, and the target display information includes the target alcohol concentration and the environmental alcohol detection result . Therefore, a more accurate target alcohol concentration can be known through the target display information, and the user can be prompted to take corresponding protection through the environmental alcohol detection result, so as to reduce the damage of the electrochemical sensor and increase the service life of the electrochemical sensor.

Referring to FIG. 2, in some embodiments, the detection period includes: a first preset period and a second preset period, the first preset period is smaller than the second preset period; the time interval includes: a use time interval and a sleep time interval; Step S102 may include, but is not limited to, including steps S201 to S202:

Step S201, if the current time is within the usage time interval, a first preset period is selected from the preset period matching information as the detection period.

Step S202, if the current time is within the sleep time interval, a second preset period is selected from the preset period matching information as the detection period.

In step S201 of some embodiments, the user's use frequency for alcohol concentration detection in one day is obtained, and a day is divided into a use time interval and a sleep time interval according to the use frequency, and specifically, the use frequency exceeds the time interval of the preset frequency by using the frequency. It is set as the use time interval, and the time interval whose usage frequency is lower than the preset frequency is set as the sleep time interval. The user does not need to detect the alcohol concentration of the gas during the sleep time interval, so there is no need to detect the alcohol concentration of the current environment too frequently, so as to save the energy consumed by the detection. However, it is highly possible for the user to detect the alcohol concentration of the gas within the usage time interval, so it is necessary to detect the alcohol concentration of the current environment in real time. The current time is within the usage time interval, and the detection period corresponds to the first preset period, and the first preset period is smaller than the second preset period, so as to detect the alcohol concentration in the current environment in real time, so as to quickly detect the alcohol concentration in the current environment. Whether to affect the initial alcohol concentration to calibrate the data for the initial breath alcohol concentration.

In step S202 of some embodiments, if the current time is in the sleep time interval, and the user's frequency of using alcohol concentration detection in the breath is very low during the sleep time interval, it is not necessary to perform alcohol concentration detection on the current environment in real time. Therefore, when the current time is in the sleep time interval, the detection period is determined to be the second preset period, thereby reducing the energy consumption for detecting the alcohol concentration in the environment.

For example, if it is determined that the use time interval is: 11:00 am-2:00 am, and the sleep time interval is 2:00 am-11:00 am. The detection period corresponding to the time interval is to detect a set of data every 3 minutes, and each set of data is detected for 1 second, and each set of data has 3 ambient alcohol concentrations. The detection period corresponding to the sleep time interval is 10 minutes to detect a group of data, each group of data is detected for 1 second, and each group of data has 3 current environmental alcohol concentrations. Therefore, if the current time is 22:00, it is determined that the current time is in the usage time interval, then the alcohol concentration of the current environment is detected every 3 minutes to obtain the environmental alcohol concentration, and each group is detected for 1 second to obtain 3 environments Alcohol concentration.

Referring to FIG. 3 , in some embodiments, the environmental alcohol detection results include: an alcohol-free environment and an alcohol-containing environment. Step S106 may include, but is not limited to, steps S301 and S302.

Step S301, if the environmental alcohol detection result is an alcohol-free environment, the initial alcohol concentration is used as the target alcohol concentration.

Step S302, if the environmental alcohol detection result is that there is an alcohol environment, the initial alcohol concentration is compensated according to the environmental alcohol concentration to obtain the target alcohol concentration.

In step S301 of some embodiments, an ambient alcohol detection result is obtained by comparing the ambient alcohol concentration with a preset concentration threshold. The ambient alcohol detection result includes: an alcohol-free environment and an alcohol-containing environment, wherein the alcohol-free environment does not mean that there is no alcohol in the environment Concentration, but the ambient alcohol concentration is lower than the preset concentration threshold, which means that the ambient alcohol concentration does not affect the initial alcohol concentration in the breath. If there is an alcohol concentration, it means that the ambient alcohol concentration in the environment is higher than the preset concentration threshold, indicating that the ambient alcohol concentration has an impact on the initial alcohol concentration. Therefore, if the environmental alcohol detection result is an alcohol-free environment, it means that the environmental alcohol concentration does not affect the initial alcohol concentration, and the initial alcohol concentration in the detected user's breath is the target alcohol concentration.

In step S302 of some embodiments, if the ambient alcohol detection result is an alcohol environment, the detected ambient alcohol concentration is greater than the preset concentration threshold, and the ambient alcohol concentration will affect the initial alcohol concentration. The concentration is compensated to obtain the target alcohol concentration.

Specifically, if the environmental alcohol detection result is an alcohol environment, it will be analyzed that the user may be drinking if a certain environmental alcohol concentration is sensed. In the past, the electrochemical sensor was installed inside the wearable device. It is in contact with the electrochemical sensor and will not come into contact with the outside air. If the blowpipe is not used, the electrochemical sensor is directly exposed to the air. At this time, the electrochemical sensor has sensed the presence of ambient alcohol concentration, so the user will blow ambient alcohol into the electrochemical sensor when exhaling to affect the initial alcohol concentration. The target alcohol concentration is obtained by compensating the initial alcohol concentration according to the environmental alcohol concentration, which makes the detection of the breath alcohol concentration more accurate.

Referring to FIG. 4 , in some embodiments, step S302 may include, but is not limited to, step S401 and step S402.

Step S401, if the environmental alcohol detection result is that there is an alcohol environment, the environmental alcohol concentration is converted according to a preset conversion algorithm to obtain a compensation value.

Step S402, correcting the initial alcohol concentration according to the compensation value to obtain the target alcohol concentration.

In step S401 of some embodiments, if the environmental alcohol detection result is an alcohol environment, it means that the initial alcohol concentration will be disturbed by the environmental alcohol concentration, so the environmental alcohol concentration is converted according to a preset conversion algorithm to obtain a compensation value. Among them, the preset conversion algorithm converts the environmental alcohol concentration to obtain the compensation value in combination with factors such as the user's exhalation time and air pressure. Therefore, the initial alcohol concentration is compensated according to the compensation value, thereby improving the detection accuracy of the alcohol concentration in the breath.

In step S402 of some embodiments, compensating the initial alcohol concentration by the compensation value mainly corrects the initial alcohol concentration according to the compensation value, so as to obtain the target alcohol concentration and improve the accuracy of breath alcohol concentration detection.

After step S103 in some embodiments, the alcohol concentration detection method further includes the steps:

Update the testing cycle based on the results of environmental alcohol testing.

It should be noted that if the environmental alcohol test result is an alcohol environment, it means that the current environmental alcohol concentration will affect the initial alcohol concentration. If the environmental alcohol test result is an alcohol-free environment, it means that the current environmental alcohol will not affect the initial alcohol concentration. . Therefore, the detection cycle is updated through the environmental detection results, so that the detection cycle can be adjusted according to the environmental detection results, so that the environmental alcohol concentration can be accurately detected when there is an alcohol environment, and the energy consumption of the detection can be saved when there is no alcohol environment.

Referring to FIG. 5 , in some embodiments, updating the detection period according to the environmental alcohol detection result may include but not limited to step S501 , step S502 , step S503 , step S504 and step S505 .

Step S501 , obtaining the period level of the detection period; wherein, the period level is inversely proportional to the detection period.

In step S502, if the result of the environmental alcohol detection is that there is an alcohol environment, the cycle level of the detection cycle is increased by one level to update the detection cycle.

Step S503, update the environmental alcohol detection result according to the updated detection period.

Step S504, if the updated environmental alcohol detection result is that there is an alcohol environment, then the updated periodic level is increased by one level until the periodic level is the preset target level.

Step S505, if the updated environmental alcohol detection result is an alcohol-free environment, restore the cycle level of the detection cycle to the initial level.

In step S502 of some embodiments, if the environmental alcohol detection result is that there is an alcohol environment, that is, the environmental alcohol concentration is greater than the preset concentration threshold, in order to further determine whether the current environmental alcohol concentration is accurate, the cycle level of the detection cycle is increased by one level, that is, shortening the detection period by one level, detecting the alcohol concentration of the current environment at a faster frequency, so as to update the environmental alcohol concentration. Therefore, when the environmental alcohol concentration is greater than the preset concentration threshold, the detection period is shortened to increase the frequency of alcohol detection in the current environment, thereby improving the accuracy of environmental alcohol concentration detection.

In step S504 of some embodiments, the updated ambient alcohol concentration is compared with a preset concentration threshold to update the ambient alcohol detection result. If the updated ambient alcohol concentration is still greater than the preset concentration threshold, the updated ambient alcohol detection result is that there is alcohol environment, continue to increase the cycle level of the detection cycle by another level. If the continuously updated environmental alcohol test result is still an alcohol environment, then increase the updated cycle level by another level until the cycle level of the detection cycle is increased to the preset target level, and the detection cycle will not be shortened, and the final target level will be used. The corresponding detection period is used to detect the alcohol concentration of the current environment.

It should be noted that the preset target level is a period level preset by the user, and each period level corresponds to a detection period. For example, the preset target level is level 4. If the period level is the initial level, the corresponding detection period is once every 10 minutes; the period level is the second level; the corresponding detection period is once every 3 minutes; the period level is the third level ; The corresponding detection cycle is once every 1 minute; the cycle level is the fourth level. The corresponding detection cycle is once every 15 seconds; the preset concentration threshold is set to 5.0 mg/100 mL. If the current time is 22:00 and the corresponding detection cycle is once every 3 minutes, the current detection cycle is the second level. If the ambient alcohol concentration is greater than 5.0mg/100mL, the cycle level of the detection cycle will be increased to the second level by one. If the ambient alcohol concentration obtained by the test every 1 minute is still greater than 5.0mg/100mL, then the cycle level of the detection cycle will be increased by one level, that is, the cycle of the detection cycle will be updated. The level is the fourth level, which means that the alcohol concentration of the current environment is detected every 15 seconds, and the cycle level is no longer modified, but the alcohol concentration of the current environment is detected every 15 seconds. Therefore, the detection cycle is adjusted according to the results of environmental alcohol detection to improve the accuracy of environmental alcohol concentration collection.

In step S505 of some embodiments, if the initial environmental alcohol detection result is an alcohol-free environment, the cycle level of the detection cycle is set to the initial level, thereby saving energy consumption for detection. In addition, if the initial environmental alcohol detection result is an alcohol environment, after the detection cycle is updated, the user perceives the presence of environmental alcohol, and the updated environmental alcohol detection result is an alcohol-free environment, and the cycle level of the updated detection cycle Reverts back to the original level, thus saving energy consumption for alcohol concentration detection.

After step S504 in some embodiments, the alcohol concentration detection method further includes:

If the cycle level is the preset target level, notify the emergency contact.
