Breath alcohol detection technology determines whether the driver has drunk alcohol by analyzing the alcohol content in the breath, and is widely used in traffic law enforcement and other fields. Its principles include wet chemical method, electrochemical method and semiconductor sensor method. Vehicle-mounted alcohol detection technology is mainly used in alcohol detection and engine interlock equipment, and its development directions include breath detection, touch detection and biological detection. Breath detection uses infrared detection technology, touch detection analyzes the alcohol content in the driver's capillaries, and biological detection uses a camera to capture eye photos and videos, and uses AI technology to analyze the alcohol content. Although these technologies are helpful for drunk driving detection, they still have shortcomings.

[0003] There are many problems with the current drunk driving detection technology: common equipment has poor anti-interference ability, high failure rate, and is easily affected by the environment, leading to false detection; relying on existing technology, daily control and investigation efficiency is low, time cost is high, and grassroots traffic police have great pressure on duty; there are loopholes in supervision, and personal information and vehicle license plate information cannot be actively identified and located, and there is a risk of "taking the blame"; new technologies are costly and not applicable; technological development is difficult to meet the new requirements of the new stage, and it is impossible to effectively judge the severity of drunk driving.

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0034] Example

[0035] The prior art related to this application includes:

[0036] (1) Breath alcohol testing technology:

[0037] Breath alcohol testing technology determines whether the driver has drunk alcohol by analyzing the alcohol content in the breath. It is widely used in traffic law enforcement, occupational health examination and other fields. The main principles of this technology are: Wet chemical method: The principle is that alcohol vapor is oxidized by acidic potassium permanganate solution, and the concentration of ethanol is inferred based on the time the solution fades, so it is called wet chemical method. The alcohol in the breath is oxidized by a mixture of potassium dichromate and sulfuric acid placed in a specially designed vial. The mixture in the bottle will change from orange to green, and the resistance change caused by the chemical reaction will also move the pointer, accurately indicating the concentration of alcohol in the breath, and converting it into blood alcohol concentration through a microcomputer. Electrochemical method: The electrochemical alcohol tester is also called a fuel cell type breath alcohol tester. Its principle is that the alcohol in the breath is oxidized by a catalyst into carbon oxide (or acetaldehyde) and water, releasing chemical energy. The chemical energy is converted into current through an electric voltmeter after being converted by an energy converter. The higher the meter reading, the higher the ethanol concentration. Semiconductor sensor method: The semiconductor breath alcohol tester uses a tin oxide semiconductor as a sensor. This type of semiconductor device has gas-sensitive properties. When the concentration of the sensitive gas in the gas it contacts increases, the resistance value it presents to the outside decreases. The advantages of semiconductor testers are small size and low price, and the disadvantage is poor anti-interference ability. It is usually only used in occasions with low requirements, such as self-testing or general qualitative testing. Breath alcohol testing technology has been used in many fields due to its convenience, rapidity and non-invasiveness. However, its accuracy and reliability have always been criticized.

[0038] (2) In-vehicle alcohol detection technology:

[0039] The main application directions of vehicle alcohol detection technology are alcohol detection and engine interlock equipment. At present, the development directions of vehicle alcohol detection technology include breath detection, touch detection, and biological detection. The principle of breath detection is infrared detection technology. The infrared absorption spectrum after drinking shows a clear absorption band. The alcohol content is determined by the degree of infrared absorption by alcohol molecules; infrared spectrum analysis has the advantages of stability and strong anti-interference ability. The principle of touch detection is to detect and analyze the alcohol content in the driver's capillaries. When the driver touches the touchpad, the touchpad emits infrared light, and the light enters the skin tissue. Part of the light will be reflected back to the skin surface and captured by the sensor. By analyzing the reflected light, the alcohol content in the skin capillaries is calculated. The principle of biological detection is to capture eye photos and videos through a camera, extract features of the pupil and iris, and use AI technology to analyze the features to obtain the alcohol content. At present, touch detection and biological detection are still in the early stages of research and development.

[0040] The disadvantages of the above-mentioned prior art include:

[0041] According to the analysis of the situation of drunk driving governance, combined with the grassroots traffic management alcohol-related law enforcement survey and the market survey of drunk driving detection equipment, the drunk driving detection equipment and methods currently used by the traffic management department cannot meet the new situation of drunk driving governance. It is concluded that the current drunk driving detection technology has the following shortcomings:

[0042] First, the commonly used equipment has poor anti-interference ability and high failure rate. The currently commonly used breath alcohol detector is easily affected by the environment and has a high failure rate, resulting in false detection. For example, when investigating and punishing drunk driving on rainy and foggy days, raindrops or moisture enter the alcohol detector, which can easily cause equipment failure and affect the normal investigation and punishment of drunk driving. Second, relying on existing technology, the efficiency of daily control and investigation is low. Taking Fujian Province as an example, the average rate of drunk driving per 10,000 people is 5.3, which means that it takes about 2,000 vehicles to investigate and punish one drunk driving; it generally takes 30 seconds to check a car, that is, each lane can only check 120 vehicles in an hour. If it is deployed at the main intersections in the city, it may also cause congestion; and the inspection efficiency is affected by the road section and time period, and it is impossible to achieve all-weather normalized drunk driving investigation and punishment; the efficiency of drunk driving investigation and punishment based on existing technology is low, the time cost is high, and the service pressure of grassroots traffic police is high. Third, the prevention and control effect of "technical prevention" is difficult to effectively improve. Due to the limitation of police force and equipment, the traffic control department currently adopts "position-style" control and random inspection for drunk driving violations, which may lead to missed inspections; some drunk drivers may get the control information in advance through social media and deliberately avoid it; and in rural areas, due to narrow roads and poor lighting, it is impossible to detect drunk driving. According to the survey, most drivers who were investigated for drunk driving again had drunk driving many times but were not caught. The existing investigation and punishment technology has low restraint on people who drive drunk again, and it has contributed to the fluke mentality of people who drive drunk; it is difficult to effectively improve the prevention and control effect of drunk driving by relying on the existing model. Fourth, there are loopholes in the existing technical supervision. The breath alcohol detector currently used can only record limited information such as the number of breaths, values, and time, and cannot actively identify and locate personal information and vehicle license plate information, resulting in certain supervision loopholes, and there is a risk of "taking the blame", which increases the fluke mentality of some people who drive drunk. Fifth, new technologies and new means are costly and not very applicable. Among the new alcohol detection technologies currently available, vehicle-mounted equipment and roadside equipment are the most common. The application of vehicle-mounted equipment (i.e., alcohol locks) requires industry consensus. Currently, the industry's acceptance is low and promotion is very difficult. Roadside equipment is mainly fixed. If it is deployed on a large scale, the cost will be high, and if it is used in a small range, the effect will be poor. Therefore, this type of equipment is not very applicable. Sixth, technological development is difficult to meet the new requirements of the new stage. At present, many departments are exploring the sentencing standards for drunk driving convictions from "blood alcohol content" to "blood alcohol content + circumstances". The existing investigation and punishment methods cannot effectively support the judgment of whether the circumstances of drunk driving are serious, and it is difficult to meet the new situation and new requirements for the handling of drunk driving.

[0043] The fundamental problem to be solved by this application is to improve the quality and efficiency of drunk driving investigation and punishment, and to enhance the role of drunk driving prevention and treatment in drunk driving investigation and punishment from a technical perspective, so as to reduce the incidence of drunk driving violations from the source. In view of the current problems in the actual application of alcohol detection technology and market development, we focus on five aspects: efficiency of investigation and punishment, flexible application, identification and positioning, situation judgment, and closed-loop supervision, to carry out targeted and comprehensive functional improvement of alcohol detection system equipment. Through this system, laser automatic detection of alcohol in the car is realized, and the vehicle license plate information and speed information are automatically identified. The information of suspected vehicles involved in alcohol is transmitted to the background system and on-duty police officers to complete accurate investigation and punishment.

[0044] Provide targeted and professional technical support for the source control of drunk driving under the new situation. The system consists of three parts: automatic screening subsystem, information transmission subsystem, and closed-loop supervision subsystem. The automatic screening subsystem consists of a laser automatic alcohol detection module, a vehicle information collection module, an automatic speed measurement module, and a location information collection module; the information transmission subsystem consists of an information processing module, an information push designated person module, and a background information recording module; the closed-loop supervision subsystem consists of a background information recording module and a processing information upload module.

[0045] The system functional modules are as follows: Figure 1 As shown, to facilitate assembly, troubleshooting and maintenance, the laser automatic alcohol detection module, vehicle information collection module, automatic speed measurement module and location information collection module are all independent modules, which are connected to each other through fiber optic coaxial connectors and mounted on a movable aluminum alloy pile device; the information processing module and the two output display ends of the background information recording module and the information push designator module are connected through a dedicated wireless network; the processing information upload module and the background information recording module are connected through a dedicated wireless network; in accordance with national network security policy regulations, data transmission and storage encryption are performed, and support is provided for setting the login IP range of the front-end and back-end system administrator accounts to prevent data transmission from being intercepted and tampered with and platform user information from being leaked.

[0046] This embodiment provides a mobile alcohol-related illegal pre-inspection system based on laser rapid detection, including:

[0047] Automatic screening subsystem, information transmission subsystem, closed-loop supervision subsystem;

[0048] The automatic screening subsystem is used to perform alcohol detection based on tunable diode light absorption spectroscopy technology combined with extremely weak light signal detection technology, and to identify and record the vehicle license plate information, the time and location information of the discovery, and obtain detection data when a suspected alcohol-related vehicle is found;

[0049] The information transmission subsystem is used to process, transmit and record the detection data;

[0050] The closed-loop supervision subsystem is used to conduct on-site inspections of vehicles suspected of being involved in alcohol-related crimes, and upload the inspection results for comparison to complete the inspection.

[0051] Optionally, the automatic screening subsystem includes a laser automatic alcohol detection module, a vehicle information collection module, and a location information collection module;

[0052] The laser automatic alcohol detection module is used to perform non-contact detection of alcohol gas concentration in the vehicle within a preset screening range based on tunable diode light absorption spectroscopy technology combined with extremely weak light signal detection technology, obtain alcohol concentration data, and identify whether it exceeds a specified threshold;

[0053] Specifically, the tunable diode light absorption spectroscopy (TDLAS) technology is used (this technology mainly utilizes the characteristics of the narrow line width and wavelength of the tunable semiconductor laser that change with the injected current to measure a single or several absorption lines of a molecule that are very close and difficult to distinguish; its technical features include high selectivity, high spectral resolution, and fast response, and is widely used in precise detection of gas traces), combined with extremely weak light signal detection technology (a scientific technology used to detect and measure very weak light signals, which may be difficult to detect due to their own low intensity or due to noise interference; this technology usually involves photoelectric conversion and signal processing, and the optical signal is converted into an electrical signal through a photodetector such as a photodiode, an avalanche photodiode (APD) or a silicon photomultiplier (SiPM), and a phase-locked amplifier or digital signal processing technology is used to enhance the signal and suppress noise), to achieve rapid detection of a moving vehicle within a distance of 20 meters under non-contact conditions, and the extracted extremely weak light signal is calculated into the concentration of alcohol gas molecules through signal digital processing technology (DSP) to analyze the alcohol concentration in the air in the vehicle and identify whether it exceeds the specified threshold.

[0054] The vehicle information collection module is used to receive the information transmitted by the laser automatic alcohol detection module. If the alcohol concentration data exceeds the preset threshold, the moving vehicle within the screening range is identified as a suspected alcohol-related vehicle, and the license plate information of the suspected alcohol-related vehicle is collected through image recognition and converted into a recognizable entry;

[0055] Specifically, the laser automatic alcohol detection module receives information transmitted. Once a moving vehicle within the screening range is identified as a suspected alcohol-related vehicle, the vehicle information collection system collects the vehicle license plate information through image recognition and converts it into a recognizable entry.

[0056] The location information collection module is used to record the time and location information once a suspected alcohol-related vehicle is detected.

[0057] Specifically, the device automatically records the time and location of power on and off when it is turned on and off; it receives information transmitted by the laser automatic alcohol detection module, and once a moving vehicle within the screening range is identified as a suspected alcohol-related vehicle, it records the time and location information once.

[0058] Optionally, the automatic screening subsystem also includes an automatic speed measurement module, which is used to receive information transmitted by the laser automatic alcohol detection module and measure the speed information of the suspected alcohol-related vehicle to determine whether it is speeding.

[0059] Specifically, the system receives information transmitted by the laser automatic alcohol detection module. Once a moving vehicle within the screening range is identified as a suspected alcohol-related vehicle, the speed information of the suspected alcohol-related vehicle is measured through radar speed measurement technology (which uses the Doppler effect of radio waves or light waves (such as lasers) to measure the speed of the target object) to determine whether the vehicle is speeding.

[0060] Optionally, the laser automatic alcohol detection module, the vehicle information collection module, the automatic speed measurement module, and the position information collection module are connected via a fiber optic coaxial connector and loaded on a movable aluminum alloy pile device.

[0061] Optionally, the information transmission subsystem includes an information processing module, an information push designated person module, and a background information recording module;

[0062] The information processing module is used to collect the information collected by the detection, form standard entries for storage, and transmit the information to the backend and the front end respectively;

[0063] Specifically, the information detected and collected by the laser automatic alcohol detection module, the vehicle information collection module, the automatic speed measurement module, and the location information collection module are aggregated to form standard entries for storage, and the information is transmitted to the backend and frontend respectively.

[0064] The information push designated person module is used to push the collected information to the police on duty;

[0065] Specifically, when the device is turned on and used, the information of the authorized police officer is entered to identify the person who is using the device and the person responsible. The information processing module transmits the information of the suspected alcohol-related vehicle to the display terminal of the on-duty police officer, prompting him to investigate and deal with the vehicle.

[0066] The background information recording module is used to receive the information of the suspected alcohol-related vehicle, record the information, and prompt the on-duty police officer of the command center to release the control information.

[0067] Specifically, the information processing module simultaneously transmits the information of the suspected alcohol-related vehicles to the background display terminal, namely, the background information recording module, records the information, and prompts the on-duty police officers at the command center to release the control information.

[0068] Optionally, the closed-loop supervision subsystem includes a processing information upload module;

[0069] The processing information upload module is used to dispatch on-duty police officers to investigate and punish vehicles suspected of alcohol-related crimes, further determine whether the driver is driving with alcohol / drunk, and upload the investigation information to the system for comparison with the background record information. If the comparison is consistent, the investigation is completed. The investigation information includes: license plate photo, driver image and time and location information.

[0070] Specifically, on-duty police officers will investigate and deal with vehicles suspected of alcohol-related violations in accordance with the law, further determine whether the driver is driving with alcohol / drunk, and upload the investigation and handling information to the system to compare it with the backend record information. If the comparison is consistent, the investigation and handling is completed. The investigation and handling information includes license plate photos, driver images, time and location information, etc.

[0071] Combined with the description of the above technical means, the system function implementation process is as follows: Figure 2 The specific implementation process is described as follows:

[0072] 1. The police officer places the device on the side of the road where it does not affect normal traffic, turns on the device, enters the information of the police officers on duty today, and the system records the time and location of the power-on information.

[0073] 2. The device uses a laser automatic alcohol detection module to quickly detect vehicles in motion within a range of 20 meters to identify whether the alcohol concentration in the air in the vehicle exceeds the specified threshold.

[0074] 3. If the alcohol concentration of the identified vehicle exceeds the threshold, it is defined as a suspected alcohol-related vehicle. The vehicle information collection module, automatic speed measurement module, and location information collection module respectively measure and collect license plate information, driver image, vehicle speed information, and time and location information.

[0075] 4. The system collects and stores various types of information and sends them to the police officers on duty and the back-end command center authorized when the system is turned on.

[0076] 5. On-duty police officers investigate and deal with vehicles suspected of alcohol-related crimes in accordance with the law. The police officers on duty at the command center release control information to further determine whether the driver is driving with alcohol / drunk, and upload the investigation information (license plate photo, driver image, time and location information, etc.) to the system and compare it with the background record information. If they are consistent, the investigation is completed.

[0077] Based on this, an embodiment of the present invention provides a mobile alcohol-related illegal pre-inspection system based on laser rapid detection, including: an automatic screening subsystem, an information transmission subsystem, and a closed-loop supervision subsystem; the automatic screening subsystem is used to perform alcohol detection based on tunable diode light absorption spectroscopy technology combined with extremely weak light signal detection technology, and identify and record the vehicle license plate information, record the time and location information of the discovery when a suspected alcohol-related vehicle is found, and obtain detection data; the information transmission subsystem is used to process, transmit and record the detection data; the closed-loop supervision subsystem is used to conduct on-site investigation and punishment of suspected alcohol-related vehicles, and upload the investigation and punishment results for comparison to complete the investigation and punishment. The specific effects are: First, improve the efficiency of investigation and punishment and avoid missed detection. The laser alcohol detection terminal automatically detects the alcohol status of passing vehicles, and detects all vehicles in motion within a range of 20 meters under non-contact conditions without interception, thereby improving the efficiency of drunk driving screening, avoiding missed detection, and eliminating the driver's fluke mentality of drunk driving. Second, improve flexibility and applicability. The system is equipped with a movable pile device, which can be set on the roadside or in the back of a pickup truck to achieve random and flexible deployment. It uses extremely weak light signal detection technology, which can adapt to detection in a completely dark environment and realize all-weather and full-range normalized inspections. Third, it can be identified and positioned. If the alcohol concentration in the vehicle reaches the set threshold after detection, the monitoring module automatically identifies and records the license plate information, driver image, and location screening position of the suspected alcohol-related vehicle, and guides the police to conduct precise investigation and punishment. Fourth, it can make a judgment on the circumstances. While detecting the alcohol content, the speed of the vehicle can be judged by the speed measuring device. On the one hand, a preliminary judgment can be made on the driver's status, and on the other hand, a preliminary judgment can be made on whether the drunk driving circumstances are serious, and evidence can be retained. Fifth, closed-loop supervision of law enforcement can be achieved. After the system identifies the suspected alcohol-related vehicle, the vehicle information is uploaded to the background. After the police complete the investigation and punishment of the suspected vehicle, they upload the information to the platform to achieve closed-loop supervision of law enforcement.

[0078] The present invention also provides a computer terminal device, comprising:

[0079] one or more processors;

[0080] A memory, coupled to the processor, for storing one or more programs;

[0081] When the one or more programs are executed by the one or more processors, the one or more processors implement a movable alcohol-related crime pre-inspection system based on laser rapid detection.

[0082] The present invention also provides a computer-readable storage medium on which a computer program is stored. When the computer program is executed by a processor, it implements a movable alcohol-related illegal pre-inspection system based on laser rapid detection.

[0083] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
