At the same time, through the high-speed data transmission capability of the 5G smart module, the real-time and accuracy of the data have been greatly improved, providing strong technical support for police use.

[0042] Below, several illustrative embodiments are used to further introduce the integrated alcohol detection and drug detection device provided by the embodiments of the present disclosure.

[0043] Please refer to Figure 1 , which shows a schematic diagram of the structure of an integrated alcohol detection and drug detection device provided by an exemplary embodiment of the present disclosure. The integrated alcohol detection and drug detection device 10 includes: a device body, an alcohol detection blow port and an infrared camera, and an alcohol detection module and a drug detection module are arranged in the device body. For the convenience of description, the integrated alcohol detection and drug detection device 10 is only referred to as device 10 for introduction.

[0044] The alcohol detection air port is connected to the device body, that is, the alcohol detection air port can be connected to the device body (such as the alcohol detection module of the device body) through a dedicated air port interface. The alcohol detection air port is used to collect the gas sample exhaled by the subject so that the device 10 can detect the alcohol concentration. The gas sample refers to the gas sample obtained from the subject, which usually contains various gas components in the breath and is used for alcohol detection.

[0045] An infrared camera is a camera that uses infrared light for imaging and can capture images in dark or low-light environments. In device 10, the infrared camera is connected to the device body, that is, the infrared camera can be connected to the device body (such as the drug detection module of the device body) through a standardized interface, such as the standardized interface Mobile Industry Processor Interface (MIPI). The infrared camera is used to collect the human iris image of the object being tested. The human iris image refers to the image of the human iris captured by the infrared camera. The iris is a circular thin film located between the black pupil and the white sclera. Its texture is unique and can be used for drug detection.

[0046] The device body refers to the main structural part of the device 10, which contains all necessary electronic components and sensors to perform detection functions and is the physical basis for the operation of the device 10.

[0047] The alcohol detection module is a component inside the device body, and is used to determine the alcohol detection result analysis based on the gas sample. That is, the gas sample collected by the alcohol detection blow port is subjected to alcohol detection analysis to determine whether it contains alcohol and the alcohol concentration, thereby determining the alcohol detection result. The alcohol detection result refers to the result obtained after the gas sample is analyzed by the alcohol detection module. The alcohol detection result is used to indicate at least one of the alcohol concentration of the gas sample of the tested object, whether the tested object has drunk driving behavior, and whether the tested object has drunk driving behavior.

[0048] The drug detection module is another component inside the device body, which is used to determine the drug detection result based on the iris image of the human eye. That is, it uses the iris image collected by the infrared camera to determine whether the subject has drug use behavior by analyzing specific features in the image, thereby determining the drug detection result. The drug detection result refers to the result obtained after the drug detection module analyzes the iris image of the human eye, which is used to determine whether the subject has taken drugs. The alcohol detection module and the drug detection module can be integrated into one module or two different modules.

[0049] It should be noted that the analysis of gas samples and the analysis of human iris images can be implemented based on the analysis methods in the prior art, and this application does not limit the specific analysis method.

[0050] In some embodiments, the integrated alcohol detection and drug detection device 10 provided in the embodiments of the present disclosure may include, in addition to the device body, alcohol detection air port and infrared camera, a display touch screen, a volume button, a power button, a speaker, a device handle, a visible light camera, a visible light camera fill light, an infrared fill light, a battery compartment back cover and at least one of an ID card reader.

[0052] 1. Alcohol detection blow port: used to collect the gas sample exhaled by the tested object. When the tested object blows into the alcohol detection blow port, the gas detection processing module inside the device will start immediately to analyze the alcohol content in the gas sample and provide the user with an accurate alcohol concentration reading.

[0053] 2. Equipment body: The internal assembly contains circuit boards and various peripheral components. These components work together to ensure that the equipment 10 can operate stably and perform complex detection tasks.

[0054] 3. Display touch screen: It is a screen that integrates display and touch control functions. Users can operate the equipment by directly touching the screen to select the test process, view the test results and set the equipment. The display touch screen is used to display images and / or text data, including application layer software interface and human-computer interaction information. Users can browse test results, adjust equipment settings or browse menus through intuitive touch operations, realizing a convenient and intuitive operation experience.

[0055] 4. Volume plus button: It is a dedicated control button for increasing the audio output volume of the device 10. The user only needs to press this button to gradually increase the volume of the speaker to ensure the clarity of the sound and the listening experience.

[0056] 5. Volume minus button: Complementary to the volume plus button, this button is used to reduce the audio output volume of the device 10. By pressing this button, the user can gradually reduce the volume to suit different listening environments or personal preferences.

[0057] 6. Power button: It is a physical button on the device 10, used to turn on or off the power of the device 10. The power button is used to switch the power state of the device 10. For example, the user can activate or shut down the device 10 by short pressing, or long press for 3 seconds to turn on the device 10, so as to achieve fast power management.

[0058] 7. Speaker: As the main audio output unit of the device 10, the speaker is responsible for sending all sound signals, including prompt information, warning information and other necessary audio feedback. It ensures that the user can receive the audio notification of the device in time.

[0059] 8. Device grip: It is a part of the device 10 designed to facilitate carrying and operation, usually located on the side or bottom of the device 10 so that the user can hold the device comfortably. This design is particularly suitable for handheld devices that need to be moved frequently or used in a mobile environment, providing additional stability and portability.

[0060] In a possible implementation, a schematic diagram of a back view of an integrated alcohol detection and drug detection device 10 provided by an exemplary embodiment of the present disclosure is as follows: Figure 3 The following is an introduction to the multiple modules involved in the figure.

[0061] 1. High-definition camera: It is a high-resolution visible light camera used to capture high-quality images or videos. In device 10, the high-definition camera is used to obtain the face image of the object to be tested for facial recognition or other image analysis functions.

[0062] 2. HD camera fill light: It is an auxiliary lighting device for visible light cameras, also known as visible light camera fill light, which is usually used in low-light environments to enhance the image capture ability of HD cameras. HD camera fill light is used for auxiliary lighting when collecting facial images. HD camera fill light provides additional light source to ensure the clarity and color accuracy of facial images.

[0063] 3. Infrared camera 1: This is a special camera that can capture the image of the human iris. The use of infrared light enables iris recognition in various lighting conditions, which is very important for security authentication and access control.

[0064] 4. Infrared Camera 2: Similar to Infrared Camera 1, this is another device used to capture iris images of human eyes. It may be used for redundancy or multi-angle capture to improve the accuracy and reliability of iris recognition.

[0065] In some embodiments, the device 10 includes at least two infrared cameras, and the at least two infrared cameras are used to simultaneously capture the iris image of the object under test, and the iris image of the object under test is the iris image of both eyes of the object under test.

[0066] 5. Infrared fill light 1: This is an infrared light source used to provide auxiliary infrared lighting when the infrared camera captures the iris image. Infrared light is invisible to the human eye, but it can be captured by the infrared camera, so that the iris can be clearly identified in a dark environment.

[0067] 6. Infrared fill light 2: This is another infrared light source, similar to infrared fill light 1, used to assist the infrared camera to capture clear iris images in dark environments. This fill light can enhance the contrast and clarity of the image and improve the accuracy of the recognition system.

[0068] In some embodiments, the device further includes one or more infrared fill lights, which are connected to the device body and are used to assist infrared lighting when collecting human eye iris images. Optionally, the infrared fill lights are connected to the device body through a digital input and output interface, such as a general purpose input / output (GPIO) interface. The infrared fill lights emit light in a specific infrared band to assist the image acquisition process. These fill lights communicate with the device body through the GPIO interface, so that the device 10 can flexibly manage and adjust the working state of each fill light. In this way, the device 10 can ensure that when collecting the human eye iris image of the object being measured, the fill lights can provide appropriate lighting, thereby optimizing the image quality and improving the accuracy and reliability of recognition. It should be noted that the figure only schematically shows two infrared cameras and two infrared fill lights, and the embodiments of the present disclosure are not limited to this.

[0069] 7. Battery compartment back cover: This is a component of the device 100, which is used to close the battery compartment. Users can replace or charge the battery by opening the back cover to ensure the continuous operation of the device.

[0070] 8. ID card reader: This is a device used to read ID card information. It can use contactless integrated circuit (IC) card reading technology, wirelessly transmit data with the dedicated chip in the ID card, read personal information, and upload it to the computer for identity verification.

[0071] In some embodiments, the device 10 may also include at least one of a cellular network processing module, a wireless fidelity (Wireless Fidelity, WIFI) module, and a global navigation satellite system (Global Navigation Satellite System, GNSS) positioning module. That is, the device 10 also supports at least one function of cellular network communication, wireless local area network communication, GNSS positioning, AI image processing, and human-computer interaction. Among them, AI image processing may include an AI image processing algorithm based on the prior art.

[0072] Based on the above-mentioned integrated alcohol detection and drug detection equipment, in some embodiments, the display touch screen is also used to display the first interface, on which the touch control for alcohol detection and the touch control for drug detection are displayed, and the touch control is used to trigger the corresponding detection process when receiving the trigger signal, that is, the user triggers the alcohol detection process by touching the touch control for alcohol detection, and the user triggers the drug detection process by touching the touch control for drug detection. In the alcohol detection process, the user blows into the alcohol detection air port, and the alcohol detection air port is used to obtain the gas sample exhaled by the object being tested, and the alcohol detection module is used to perform alcohol detection and analysis on the gas sample to determine the alcohol detection result. In the drug detection process, the infrared camera is used to collect the human eye iris image of the object being tested, and the drug detection module is used to perform drug detection and analysis on the human eye iris image to determine the drug detection result.

[0073] The first interface can be the initial interface of the device, or the standby interface, or the unlock interface. The initial interface is the first interface displayed after the device is started, the standby interface is the interface displayed after the device is started and initialized, and the unlock interface is the interface displayed after the device is unlocked (that is, the device is in the locked state and the user enters the correct unlocking method). The following only takes the first interface as the standby interface displayed after the device is turned on as an example for explanation.

[0074] In the startup process of the integrated alcohol and drug detection device, the components involved in each step and their functions are as follows: the power button is also used to switch the device from the off state to the on state when receiving a preset pressing operation, and the device enters the initialization process; the speaker is also used to play the first prompt sound when the device is initialized, and the first prompt sound is used to indicate that the device has completed initialization; the display touch screen is also used to display the first interface when the device enters the standby state. Please refer to Figure 4 , which shows a schematic diagram of the startup process of an integrated alcohol detection and drug detection device provided by an exemplary embodiment of the present disclosure. The startup process of the device includes the following steps:

[0075] Step 401, when a preset pressing operation on a power button is received, the device is switched from a power-off state to a power-on state.

[0076] The preset pressing operation is a preset pressing operation for triggering the device to switch from the off state to the on state, for example, the preset pressing operation is a long press operation for 3 seconds. Switching the device from the off state to the on state includes: connecting the power of the device, starting the operating system of the device, and preparing to enter the working state.

[0077] Step 402, perform device initialization.

[0078] The self-test and configuration process performed by the device after it is powered on to ensure that all systems and components are functioning properly. The self-test includes a series of tests performed by the device's internal systems to ensure that both hardware and software components are in a normal state.

[0079] Step 403, after the device initialization is completed, a first prompt tone is played, and the first prompt tone is used to indicate that the device initialization is completed.

[0080] After the device is initialized, the speaker plays the first prompt tone to notify the user that the initialization process has ended. The first prompt tone can be a "beep" prompt tone, which usually consists of two short tones, to remind the user that the device is ready.

[0081] Step 404, entering the standby state and displaying the standby interface.

[0082] The standby state is a low-power state that the device is in after initialization, ready to receive user input or wait for further operation instructions. The standby interface is displayed on the display touch screen. The standby interface is the interface displayed by the device in the standby state, usually including some basic operation options and device status information. The standby interface displays touch controls for alcohol detection and touch controls for drug detection. The touch controls are used to trigger the corresponding detection process when receiving a trigger signal, thereby entering the preparation state of the corresponding detection process.

[0083] The touch controls displayed on the standby interface are touchable graphic elements, such as buttons or icons, and users can interact with the device by touching. The alcohol detection touch control is a touch control on the standby interface used to trigger the alcohol detection process, that is, the alcohol detection touch control is the entrance to the alcohol detection interface, and the drug detection touch control is a touch control on the standby interface used to trigger the drug detection process, that is, the drug detection touch control is the entrance to the drug detection interface.

[0084] The trigger signal is a specific touch action performed by the user, such as a single-click signal, which is used to trigger the device to enter a corresponding detection process.

[0085] In an illustrative example, the device enters a standby state and displays the following on the display touch screen: Figure 5 The standby interface shown has two buttons, "Alcohol Detection" and "Drug Detection". Clicking any one of the buttons can trigger the device to enter the preparation state of the corresponding detection process.

[0086] In the alcohol detection process of the integrated alcohol detection and drug detection equipment, the components involved in each step and their functions are as follows: the display touch screen is also used to display the alcohol detection interface when receiving the trigger signal of the alcohol detection touch control, and the alcohol detection interface displays a start control; when receiving the trigger signal of the start control on the alcohol detection interface, the alcohol detection process is started; the speaker is used to play the second prompt sound, and the second prompt sound is used to instruct the subject to blow into the alcohol detection blow port. The subject blows into the alcohol detection blow port, and the alcohol detection blow port is used to obtain the gas sample exhaled by the subject. The alcohol detection module is used to perform alcohol detection and analysis on the gas sample to determine the alcohol detection result. The display touch screen is also used to display the alcohol detection result.

[0087] Please refer to Figure 6 , which shows a schematic diagram of an alcohol detection process of an integrated alcohol detection and drug detection device provided by an exemplary embodiment of the present disclosure. The alcohol detection process of the device includes the following steps:

[0088] Step 601, when a trigger signal of the alcohol detection touch control is received, an alcohol detection interface is displayed, and a start control is displayed on the alcohol detection interface.

[0089] The user touches the touch control of the alcohol detection, the device responds to the corresponding trigger signal, and displays the alcohol detection interface on the display touch screen. The alcohol detection interface displays a start control for starting the alcohol detection process, and the device is ready to perform alcohol detection.

[0090] The start control displayed on the alcohol detection interface is a touchable graphical element, such as a button or icon, that a user can touch to interact with the device. The start control on the alcohol detection interface is a touch control used to start the alcohol detection process.

[0091] Step 602, when a trigger signal of a start control on the alcohol detection interface is received, the alcohol detection process is started.

[0092] The trigger signal of the start control on the alcohol detection interface is a specific touch action performed by the user, such as a single click signal, which is used to trigger the device to start the alcohol detection process.

[0093] In some embodiments, the above steps 601 and 602 can be replaced and implemented as follows: when a trigger signal of the alcohol detection touch control is received, the alcohol detection process is started. That is, the user only needs to touch the alcohol detection touch control once to directly trigger and start the alcohol detection process without additional operations. Such a design simplifies user operations and makes the alcohol detection process smoother and more user-friendly.

[0094] Step 603, play a second prompt tone, the second prompt tone is used to instruct the subject to blow into the alcohol detection blowing port.

[0095] The speaker plays a second prompt tone, which is a specific prompt tone. This prompt tone is used to remind the subject to blow into the alcohol detection blowhole.

[0096] Step 604, obtaining a gas sample exhaled by the subject.

[0097] The subject needs to blow into the alcohol detection port according to the device's instructions. The alcohol detection port obtains the breath sample exhaled by the subject in order to detect the alcohol concentration.

[0098] Step 605, perform alcohol detection and analysis on the gas sample to determine the alcohol detection result.

[0099] The alcohol concentration in the gas sample is measured by built-in software to determine the alcohol test result, which is used to indicate at least one of the alcohol concentration of the gas sample of the tested object, whether the tested object has drunk driving behavior, and whether the tested object has been driving under the influence.

[0100] Optionally, the alcohol test result includes the alcohol concentration of the gas sample of the subject, at least one of a first test result and a second test result, the first test result is used to indicate whether the subject is driving under the influence of alcohol and the alcohol concentration exceeds the legal standard for driving under the influence of alcohol, and the second test result is used to indicate whether the subject is driving under the influence of alcohol.

[0101] The alcohol concentration is usually expressed in milligrams per 100 milliliters of blood (mg / 100mL) or percentage (%). When the alcohol concentration exceeds the legal drunk driving standard, the first test result is determined to indicate that the subject has drunk driving behavior, and when the alcohol concentration exceeds the legal drunk driving standard, the second test result is determined to indicate that the subject has drunk driving behavior.

[0102] It should be noted that the analysis of the gas sample can be implemented based on the analysis method in the prior art, and the present disclosure does not limit the specific analysis method.

[0103] Step 606, display the alcohol test result.

[0104] The device will present the alcohol test results on the display touch screen. The alcohol test results can be directly displayed as digital readouts or as graphical icons or progress bars, providing users with intuitive visual feedback.

[0105] In order to further enhance the user experience, in addition to visual display, the device also provides multiple notification methods such as sound prompts or vibration feedback. When the test results come out, the device can emit a clear prompt sound, or remind the user through slight vibration, ensuring that the user can learn the test results in time, whether in a noisy environment or in a visually inconvenient situation. Such a design takes into account the needs of different users, making the device more user-friendly and easy to use. The present disclosure does not limit the output method of the alcohol test results.

[0106] In an illustrative example, the user first clicks the "Alcohol Test" button on the display touch screen to enter the alcohol test process. After entering the alcohol test process, click the start control on the displayed alcohol test interface and follow the instructions of the speaker to operate. After the device completes the alcohol test and data processing, the device's display touch screen displays the alcohol test results, which may include conclusions such as alcohol concentration, whether the person is driving under the influence of alcohol, and whether the person is drunk driving.

[0107] In the drug detection process of the integrated alcohol detection and drug detection device, the components involved in each step and their functions are as follows: the display touch screen is also used to display the drug detection interface when receiving the trigger signal of the touch control of the drug detection, and the drug detection interface displays a start control; when receiving the trigger signal of the start control on the drug detection interface, the drug detection process is started; the speaker is used to play the third prompt sound, and the third prompt sound is used to indicate that the infrared camera is pointed at the eyes of the subject to be tested for collection. The infrared camera is used to collect the human iris image of the subject to be tested, and the drug detection module is used to perform drug detection analysis on the human iris image to determine the drug detection result. The display touch screen is also used to display the drug detection result.

[0108] Please refer to Figure 7 , which shows a schematic diagram of a drug detection process of an integrated alcohol detection and drug detection device provided by an exemplary embodiment of the present disclosure. The drug detection process of the device includes the following steps:

[0109] Step 701, when a trigger signal of a touch control for drug taking detection is received, a drug taking detection interface is displayed, and a start control is displayed on the drug taking detection interface.

[0110] The user touches the touch control of drug detection, the device responds to the corresponding trigger signal, and displays a drug detection interface on the display touch screen. The drug detection interface displays a start control for starting the drug detection process, and the device is ready to perform drug detection.

[0111] The start control displayed on the drug detection interface is a touchable graphical element, such as a button or icon, that a user can touch to interact with the device. The start control on the drug detection interface is a touch control used to start the drug detection process.

[0112] Step 702, when a trigger signal of a start control on the drug taking detection interface is received, the drug taking detection process is started.

[0113] The trigger signal of the start control on the drug detection interface is a specific touch action performed by the user, such as a single click signal, which is used to trigger the device to start the drug detection process.

[0114] In some embodiments, the above steps 701 and 702 can be replaced by: when a trigger signal of the touch control for drug detection is received, the drug detection process is started. That is, the user only needs to touch the touch control for drug detection once to directly trigger and start the drug detection process without additional operations. Such a design simplifies user operations and makes the drug detection process smoother and more user-friendly.

[0115] Step 703: play a third prompt tone, where the third prompt tone is used to instruct the infrared camera to be directed toward both eyes of the object to be measured for collecting images.

[0116] The speaker plays a third prompt tone, which is a specific prompt tone. This prompt tone is used to remind the collector to point the infrared camera toward the eyes of the object to be measured for collection.

[0117] Step 704: Acquire an iris image of the subject.

[0118] The collector needs to follow the instructions of the device and point the infrared camera toward the eyes of the subject to collect data. The infrared camera collects the iris image of the subject. The speaker plays the fourth prompt tone, which is used to indicate that the collection is completed.

[0119] Step 705, performing drug detection analysis on the human iris image to determine a drug detection result.

[0120] The built-in software is used to analyze the human iris image for drug detection and determine the drug detection result, which is used to indicate whether the subject has drug use behavior.

[0121] In some embodiments, a preset machine learning model is used to perform drug detection analysis on a human iris image to determine a drug detection result. The process of performing drug detection analysis on a human iris image through a preset machine learning model and determining a drug detection result generally includes the following key steps: 1. Image preprocessing: The collected human iris image may contain factors such as noise and uneven illumination that affect the quality of the analysis, so preprocessing is required, such as noise reduction, contrast enhancement, and size standardization. 2. Feature extraction: Extract features that are helpful for drug detection from the preprocessed human iris image. These features may include texture, color, shape, etc. 3. Data analysis: Input the extracted features into the pre-trained machine learning model, and output the drug detection result. 4. Model update: Over time, the model may need to be updated to improve its accuracy. This can be achieved by continuously learning new data samples. 5. Wireless communication: Through wireless communication means such as 5G and WIFI, the model can be updated remotely, new data can be received, or the drug detection results can be wirelessly uploaded to a remote server for further analysis. It should be noted that the analysis of human iris images can be implemented based on the analysis method in the prior art, and the present disclosure does not limit the specific analysis method.

[0122] Step 706, display the drug abuse test results.

[0123] The device can display the drug test results in digital or graphical form on the display touch screen. In some embodiments, in addition to the visual display, the device can also provide sound prompts or vibration feedback. Analogously refer to the output method of the alcohol test results, which will not be repeated in this embodiment.

[0124] In an illustrative example, the user first clicks the "Drug Detection" button on the display touch screen to enter the drug detection process. After entering the drug detection process, click the start control on the displayed drug detection interface. After hearing the speaker playing the prompt sound of collecting the iris image of the subject, the collector holds the device and points the infrared camera toward the eyes of the subject to collect. When the speaker hears the sound of prompting the completion of the collection, the collection is completed. Waiting for data processing, after the drug detection is completed, the drug detection results are displayed on the display touch screen, including the conclusion of whether drugs are used, etc., which is not limited by the present disclosure.

[0125] In summary, the integrated alcohol detection and drug detection equipment provided by the embodiments of the present disclosure includes the following beneficial effects: 1. Integrated design: The equipment is a mobile portable device that integrates alcohol and drug detection functions, allowing law enforcement or security personnel to perform two tests on the same device, thereby improving work efficiency. 2.
