Description

Technical Field

[0001] This invention relates to the field of drunk driving detection technology, and in particular to a method for rapidly correlating alcohol test records with active breath alcohol test records. Background Technology

[0002] Two types of breathalyzers are used when detecting drunk driving: rapid screening breathalyzers (such as...) Figure 7 (as shown) and a breath alcohol content analyzer (also known as a breath alcohol meter or exhaled alcohol detector, such as...) Figure 8 As shown), the industry refers to the measurement functions of these two instruments as rapid screening alcohol detection (rapid screening detection) and active breath alcohol detection (active detection), respectively. For example, Chinese patents with application numbers 201220232109.4 and 201721173387.6 are typical examples of rapid screening alcohol detection devices. Figure 7 As shown, these instruments are generally shaped like a baton. Breathalyzers, on the other hand, are traditional instruments that require blowing into a mouthpiece for accurate measurement. For example, Chinese patents with application numbers 02250564.4 and 200820235094.0 are typical examples of breathalyzers. In screening for drunk driving, a rapid breathalyzer is typically used for initial screening. If the result is positive, a breathalyzer is then used for active exhalation testing. This approach improves testing efficiency while ensuring the accuracy of the screening results.

[0003] Some products integrate rapid screening and active detection functions into one instrument. For example, Chinese patents with application numbers 201120152280.X and 201820145526.2 both have two alcohol sensors and two air pumps to realize rapid screening and active exhalation detection functions respectively. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a method for quickly identifying the correlation between alcohol test records and active breath alcohol test records, thereby resolving disputes caused by improper operation or instrument malfunction during alcohol testing.

[0005] To achieve the above objectives, the present invention provides a method for rapidly correlating alcohol test records with active breath alcohol test records, comprising:

[0006] Step 10: When conducting a rapid screening alcohol test or active breath alcohol test on the subject, simultaneously take a facial photo of the subject that can be used for facial recognition.

[0007] Step 20: Upload the alcohol test results and corresponding facial photos to the drunk driving management system database;

[0008] Step 30: Each alcohol test result record and its corresponding face photo in the database are considered as one alcohol test record in the database. Within the preset range of alcohol test records, all alcohol test records within the range that are identified as the same person based on the face photo recognition results are judged to be related to each alcohol test record. Other alcohol test records within the range are judged to be unrelated to each alcohol test record.

[0009] Step 40: According to the preset rules, for all alcohol test records that are related within the range, determine whether each alcohol test record is abnormal by combining the alcohol test results contained in each alcohol test record. For alcohol test records that are not related within the range, determine whether each alcohol test record is abnormal by combining the alcohol test results of each alcohol test record.

[0010] The alcohol test result record includes the alcohol test type, alcohol test result data, and test time.

[0011] The rapid alcohol detection device for quickly screening a person for alcohol testing and the breath alcohol detection device for actively exhaling alcohol testing each have an alcohol detection module, a camera, and a communication module. The alcohol detection module is used to perform the corresponding alcohol test, the camera is used to take a facial photo of the person being tested that can be used for facial recognition while conducting the alcohol test, and the communication module is used to transmit the alcohol test result provided by the alcohol detection module and the corresponding facial photo of the person being tested provided by the camera to the database of the drunk driving management system.

[0012] The association method further includes step 50: issuing an alarm for alcohol test records that are judged to be abnormal.

[0013] The preset alcohol test recording range is limited by the detection time of the alcohol test results recording.

[0014] The preset alcohol test record range is alcohol test records within a test time of 2 hours to 24 hours.

[0015] The server of the drunk driving management system is equipped with facial recognition software and algorithms. When running, the software and algorithms can compare the facial photos in each alcohol test record in the drunk driving management system database one by one. The current alcohol test record to be compared is called the comparison record, and the other alcohol test records to be compared are called the comparison records. The drunk driving management system determines whether there is a correlation between the comparison record and the comparison record based on the comparison results.

[0016] The one-to-one comparison process is as follows:

[0017] First, take the latest alcohol test record within the preset range of the database as the comparison record, and compare it with each of the previous alcohol test records. When the comparison shows the same face, it is determined that there is a correlation between the comparison record and the comparison record. If the comparison does not show the same face, it is determined that there is no correlation between the comparison record and the comparison record.

[0018] Then, take the previous alcohol test record within the preset range of the database as the comparison record and compare it with each of the alcohol test records before it. If the comparison shows the same face, it is determined that there is a correlation between the comparison record and the comparison record. If the comparison does not show the same face, it is determined that there is no correlation between the comparison record and the comparison record.

[0019] In this manner, the alcohol test record preceding the previous comparison record is taken as the current comparison record, and compared with each of the preceding alcohol test records. Similarly, it is determined whether there is a correlation between the comparison record and the comparison record, until the first alcohol test record is taken as the current comparison record, thus completing this one-to-one comparison.

[0020] Once all the alcohol test records that need to be compared have been compared once, the comparison ends, and a new comparison will be performed when a new alcohol test record is received.

[0021] When a new alcohol test record is received, only the new alcohol test record is used as the comparison record and compared with all the previous alcohol test records once. Instead of comparing the previous alcohol test records with each other, the comparison time is saved.

[0022] Alcohol test records corresponding to the rapid screening alcohol test type are called rapid screening alcohol test records, and alcohol test records corresponding to the active breath alcohol test type are called active breath alcohol test records; the preset rules of step 40 include:

[0023] (1) If the two alcohol test records that are determined to be related are a rapid screening alcohol test record and an active breath alcohol test record, and the rapid screening alcohol test was performed first and the active breath alcohol test was performed later, if the time interval between the two tests does not exceed the specified value, then the two alcohol test records are normally related; if the time interval between the two tests exceeds the specified value, then the two alcohol test records are abnormally related.

[0024] (2) If the two alcohol test records that are determined to be related are a rapid screening alcohol test record and an active breath alcohol test record, and the active breath alcohol test was performed first and the rapid screening alcohol test was performed later, then the correlation between the two alcohol test records is abnormal.

[0025] (3) If two or more alcohol test records that are judged to be related are active breath alcohol test records, then the correlation between these alcohol test records is abnormal.

[0026] (4) If one of the two or more alcohol test records that are identified as related is associated with one or more active breath alcohol test records, then the association between these alcohol test records is abnormal.

[0027] (5) If one of the two or more alcohol test records that are determined to be related is a rapid screening alcohol test record with a positive alcohol test result, and is related to an active breath alcohol test record with a zero alcohol test result, then the correlation between these two alcohol test records is abnormal.

[0028] (6) If one of the two alcohol test records that are determined to be related is a rapid screening alcohol test record with a negative alcohol test result, and is related to an active breath alcohol test record with a non-zero alcohol test result, then the correlation between these two alcohol test records is abnormal.

[0029] (7) If a rapid screening of alcohol test records with a negative result or an active breath alcohol test record does not find a related alcohol test record, then the correlation of the alcohol test record is normal.

[0030] (8) If the alcohol test result data of the rapid screening alcohol test record is positive, but no related active breath alcohol test record is found according to the face comparison, then the correlation of the alcohol test record is abnormal.

[0031] In a certain judgment, when two or more preset rules overlap, the final judgment criterion is as follows: if all applicable preset rules are judged to be of normal correlation, then these alcohol test records are ultimately judged to be of normal correlation; if one applicable preset rule is judged to be of abnormal correlation, then these alcohol test records are ultimately judged to be of abnormal correlation.

[0032] The alcohol test result record also includes information about the person being tested, the testing location, the vehicle, the person conducting the test, and the equipment.

[0033] The alcohol test record also includes a record number.

[0034] The preset range of alcohol test records is limited by the record number of the alcohol test record.

[0035] In summary, the method for rapidly linking alcohol test records with active breath alcohol test records of the present invention can standardize the management of drunk driving investigations. Attached Figure Description

[0036] The technical solution and other beneficial effects of the present invention will become apparent from the following detailed description of specific embodiments of the invention, in conjunction with the accompanying drawings.

[0042] Figure 8 This is a schematic diagram of an existing breath alcohol content detector. Detailed Implementation

[0043] For this reason, see Figure 6 The flowchart illustrates the method for rapidly linking alcohol test records and active breath alcohol test records according to the present invention. This linking method mainly includes:

[0044] Step 10: When conducting a rapid screening alcohol test or active breath alcohol test on the subject, simultaneously take a facial photo of the subject that can be used for facial recognition.

[0045] Step 20: Upload the alcohol test results and corresponding facial photos to the drunk driving management system database;

[0046] Step 30: Each alcohol test result record and its corresponding face photo in the database are considered as one alcohol test record in the database. Within the preset range of alcohol test records, all alcohol test records within the range that are identified as the same person based on the face photo recognition results are judged to be related to each alcohol test record. Other alcohol test records within the range are judged to be unrelated to each alcohol test record.

[0047] Step 40: According to the preset rules, for all alcohol test records that are related within the range, determine whether each alcohol test record is abnormal by combining the alcohol test results contained in each alcohol test record. For alcohol test records that are not related within the range, determine whether each alcohol test record is abnormal by combining the alcohol test results of each alcohol test record.

[0048] Step 50: Issue an alarm for alcohol test records that are deemed abnormal.

[0049] The alcohol test result record includes the alcohol test type, alcohol test result data, and test time; the alcohol test record corresponding to the alcohol test type of rapid screening alcohol test is called the rapid screening alcohol test record, and the alcohol test record corresponding to the alcohol test type of active breath alcohol test is called the active breath alcohol test record.

[0050] This invention addresses disputes arising from improper operation and instrument malfunctions by examining the correlation between rapid screening of alcohol test records and active breath alcohol test records within a drunk driving management system.

[0051] The term "correlation" refers to the relationship between rapid screening of alcohol test records and active breathalyzer records in terms of testing time and alcohol test result data. The alcohol test result data can refer to both quantitative values ​​and qualitative assessments. Specifically, it is divided into correlation in testing time and correlation in alcohol test result data.

[0052] The correlation in testing time refers to the sequential and time-interval relationship between rapid screening alcohol testing and active breathalyzer testing. In terms of sequence, on-site screening personnel generally first use a rapid screening alcohol tester for initial screening. If the alcohol test result is positive, then a breathalyzer test is used for evidence collection. There is generally no reason to reverse this process. It should be noted that a positive alcohol test result here means the result exceeds a pre-set value. This value can be zero or any non-zero value. For example, if set to zero, any result exceeding zero is considered positive. If it is not zero, for example, set to 10mg / 100ml, any result exceeding 10mg / 100ml is considered positive, while 9mg / 100ml is considered a negative result. Of course, as an exception, if the on-site investigators can clearly see that the person being tested has been drinking, they may not need to conduct a rapid screening alcohol test first and can directly use a breathalyzer. In this case, only the voluntary breathalyzer test record will be available, and there will be no rapid screening alcohol test record. Regarding the time interval, a voluntary breathalyzer test should be conducted immediately after the rapid screening alcohol test. However, sometimes the person being tested will find various reasons to delay or even refuse the voluntary breathalyzer test. Therefore, generally speaking, a difference of a few minutes to tens of minutes between the two is possible, but if it exceeds several hours, it is abnormal. In cases where the person being tested is uncooperative, there may be problems with the time sequence and time interval between the rapid screening alcohol test and the voluntary breathalyzer test. For example, if a person undergoes a rapid screening alcohol test and the result is positive, but does not undergo an active breathalyzer test, then that positive rapid screening alcohol test record cannot be traced back to a corresponding active breathalyzer test record; or if a person undergoes a rapid screening alcohol test and the result is positive, but does not immediately undergo an active breathalyzer test, but delays for two hours; or if a third party takes the blame for a positive rapid screening alcohol test and undergoes an active breathalyzer test; or if a positive rapid screening alcohol test record can be traced back to more than one active breathalyzer test record; or, if there is no rapid screening alcohol test record, but there are more than two active breathalyzer test records.

[0053] The correlation between test results refers to the fact that a positive result from a rapid screening alcohol test generally indicates that the person tested has consumed alcohol, and the corresponding result from an active breathalyzer test will typically show a value greater than zero or a certain specified value. Conversely, a negative result from a rapid screening alcohol test generally indicates that the person tested has not consumed alcohol, and the corresponding result from an active breathalyzer test will typically show a value of zero or below a certain specified value, or no active breathalyzer test may have been performed. However, when the alcohol testing device malfunctions, the relationship between the two test results may also be incorrect. For example, a negative result from a rapid screening alcohol test may occur, but a result from an active breathalyzer test may be greater than zero or a certain specified value; or a positive result from a rapid screening alcohol test may occur, but a result from an active breathalyzer test may be equal to zero or below a certain specified value.

[0054] It should be noted that the alcohol test type mentioned above, also known as the measurement mode, includes active breathalyzer testing (labeled "active") and rapid screening alcohol testing (labeled "screening"). The alcohol test result data includes both quantitative values ​​and units, as well as qualitative judgments (e.g., positive, negative). The alcohol test result record may also include the testing location, the person being tested (name, driver's license number), vehicle information (license plate number, vehicle model), the tester's information (name, ID), and equipment information (equipment ID, instrument model). The alcohol test type, result data, and test time are mandatory information; other information can be provided as needed. After a test is completed, the alcohol detector automatically generates a record of the result and stores it within the detector. Once this record is uploaded to the server database, it is combined with the facial photograph taken during the test to create a single alcohol test record in the database.

[0055] The alcohol test record also includes a record sequence number (hereinafter referred to as the sequence number). The record sequence number is assigned to each alcohol test record by the database according to the order in which the alcohol test results are received when uploaded to the database by the alcohol test device. The preset range of alcohol test records can be limited by the test time in the alcohol test result record, such as taking a certain time period; or it can be limited by the record sequence number of the alcohol test record, such as taking the record sequence number within a certain natural number range.

[0056] like Figure 1 As shown, it is a schematic diagram of the system architecture of a preferred embodiment of the method for quickly identifying the association between alcohol test records and active breath alcohol test records of the present invention.

[0057] In practical use, the correlation between rapid screening alcohol test records and active breath alcohol test records on the same breath alcohol tester can be examined, as can the correlation between alcohol test records from a single rapid screening alcohol tester and a single breath alcohol tester.

[0058] Therefore, this invention uses a camera and a facial recognition method based on a facial photograph to associate alcohol test records between two types of alcohol tests.

[0059] To this end, cameras are installed on both the rapid screening alcohol tester and the breathalyzer. These cameras can take pictures during the rapid screening alcohol test and the active breathalyzer test, capturing facial images of the person being tested that can be recognized by facial recognition. The facial images of the person being tested during the active breathalyzer test or the rapid screening alcohol test are stored in the instrument's large-capacity memory and uploaded to the server of the drunk driving management system along with the alcohol test results via wireless communication (e.g., 4G, 5G) or wired communication (e.g., USB connection). Because rapid alcohol testing devices are generally used for preliminary screening, their functions are relatively simple. Most products on the market are shaped like a baton, and their displays are mostly smaller than 1.3 inches, unsuitable for displaying photos taken by cameras. Even if photos are taken, no one cares about their purpose. The photo files are image files, which are larger than the text files recording the alcohol test results. This requires more storage, increasing costs. Furthermore, uploading via 4G consumes a lot of data and is slow, while uploading via USB requires manual upload from the office, impacting work efficiency. Therefore, currently, all rapid alcohol testing devices on the market do not have cameras, rarely have 4G modules, and are rarely used for data upload from the office via USB. No one uploads photos via 4G or USB. Simply put, current rapid alcohol testing devices lack both the function of taking photos during rapid alcohol testing and the motivation and purpose for doing so. No one has considered using photos taken during rapid alcohol testing for facial recognition to address disputes caused by improper operation or device malfunctions. Therefore, it is necessary to redesign the rapid alcohol detection device, for example, by installing a camera, increasing the display size, adding a 4G module, and increasing the storage capacity, to accommodate the need for taking photos and uploading photos to the server via the 4G module. For breathalyzers, since the test subject must hold the mouthpiece and blow air while the breath is being taken, and facial recognition has certain requirements for the captured image, the camera's installation position must ensure that a complete frontal image of the face is captured. In summary, rapid alcohol detection devices for quickly screening test subjects and breathalyzers for actively conducting breath alcohol tests should each have at least an alcohol detection module, a camera, and a communication module. The alcohol detection module performs the corresponding alcohol test, the camera captures a facial image of the test subject simultaneously for facial recognition, and the communication module transmits the alcohol test result provided by the alcohol detection module and the corresponding facial image provided by the camera to the drunk driving management system's database.

[0060] Therefore, such as Figure 1As shown, a drunk driving management system is established. The hardware of this system typically consists of a server, a network, and terminal computers. The server is located in a server room or rented from a third party, while the terminal computers are located in the offices of each management department. The two are connected via a network (e.g., a VPN). The drunk driving management system software (i.e., the drunk driving management platform) is installed on the server. Terminal computers within the management departments can access the drunk driving management system software on the server through a browser. This software generally adopts a B / S architecture. During operation, the breathalyzer (i.e., the rapid screening device and breathalyzer shown in the diagram) uploads the alcohol test results of the tested individuals to the server in real time via 4G wireless. The drunk driving management system software stores the alcohol test results data in a database. A typical drunk driving management system software is shown below. Figure 2 As shown, multiple alcohol test records are displayed on the drunk driving management system software, including a quick screening function for alcohol test records. Figure 2 The term "screening" (referred to as "screening") also includes records of proactive breathalyzer tests. Figure 2 (referred to as "active" in Chinese), and is generally displayed in chronological order.

[0061] To this end, facial recognition software and algorithms are also installed on the server of the drunk driving management system. When running, this software and algorithm can compare the facial photos in each alcohol test record in the drunk driving management system database one by one. Here, the current alcohol test record being compared is called the comparison record, and the other alcohol test records being compared are called the compared records. The drunk driving management system performs preliminary labeling based on the comparison results, as follows (see below). Figures 2 to 5 This is a schematic diagram illustrating the implementation process of a preferred embodiment of the method for rapidly identifying the association between alcohol test records and active breath alcohol test records according to the present invention.

[0062] like Figure 2 As shown, there are currently only 6 alcohol test records in the database record table, of which the 6th record is the most recent alcohol test record. At this time, the correlation column of each alcohol test record is blank.

[0063] First, take the latest alcohol test record (record 6) from the database table as the comparison record and compare it with the previous alcohol test record (record 5). If the comparison matches the same face, mark the compared record as "record 6" in the "Relevance" column, and simultaneously mark "record 5" in the "Relevance" column of record 6. This indicates that record 5 and record 6 are the same face. If they are not identified as the same face, no marking is made. After the comparison record is compared with record 5, it is compared with the previous alcohol test record (record 4), and the marking is done in the same way. This process is repeated until a comparison has been made with the first alcohol test record (record 1). In this round of comparison, record 6 and record 5 show the same face. Therefore, record 5 is marked as "Record 6" in the relevance column, and record 6 is marked as "Record 5" in the relevance column. Records 4, 3, 2, and 1 do not show the same face as record 6 and are not marked. Therefore, the relevance marking results in the record table after this round are as follows: Figure 3 As shown.

[0064] Next, take the previous alcohol test record (record 5) from the database table as the comparison record and compare it with the previous alcohol test record (record 4). If the comparison matches the same face, mark the comparison record as "record 4" in the "Relevance" column, and simultaneously mark it as "record 5" in the "Relevance" column of record 4. This indicates that record 4 and record 5 are the same face. If they are not identified as the same face, no marking is made. After the comparison record is compared with the 4th alcohol test record, it is compared with the previous alcohol test record (record 3), and the marking is done in the same way as before. This process is repeated until a comparison has been made with the first alcohol test record (record 1). In this round of comparison, since the 5th alcohol test record is not the same face as records 4, 3, 2, and 1, these alcohol test records are not marked. After this round, the correlation marking results in the record table are still as before. Figure 3 As shown.

[0065] Next, take the previous alcohol test record (record 4) from the database table as the comparison record and compare it with the previous alcohol test record (record 3). If the comparison matches the same face, mark the comparison record as "record 3" in the "Relevance" column, and simultaneously mark it as "record 4" in the "Relevance" column of record 3. This indicates that record 3 and record 4 are the same face. If they are not identified as the same face, no marking is made. After the comparison record is compared with the third alcohol test record, it is compared with the previous alcohol test record (record 2), and the marking is done in the same way. This process is repeated until it has been compared with the last alcohol test record (record 1). In this round of comparison, since the fourth alcohol test record is not the same face as records 3, 2, and 1, these alcohol test records are not marked. After this round, the correlation marking results in the record table are still as before. Figure 3 As shown.

[0066] Next, take the previous alcohol test record (record 3) from the database table as the comparison record and compare it with the previous alcohol test record (record 2). If the comparison shows the same face, mark the comparison record as "record 2" in the "Relevance" column, and simultaneously mark it as "record 3" in the "Relevance" column of record 2. This indicates that record 2 and record 3 are the same face. If they are not identified as the same face, no marking is made. After the comparison record is compared with the second alcohol test record, it is compared with the previous alcohol test record (record 1), and the marking is done in the same way as before. In this round of comparison, the comparison result of the third alcohol test record and the second alcohol test record shows the same face. Therefore, record 3 is marked as "record 2" in the "Relevance" column, and record 2 is marked as "record 3" in the "Relevance" column. Record 1 and record 3 are not the same face, so no marking is made. Therefore, the result of the correlation marking in the record table after this round is as follows. Figure 4 As shown.

[0067] Next, take the previous alcohol test record (Record 2) from the database table as the comparison record and compare it with its predecessor (Record 1). If the comparison matches the same face, mark the compared record as "Record 2" in the "Relevance" column, and simultaneously mark Record 2 as "Record 1" in the "Relevance" column. This indicates that Record 1 and Record 2 represent the same face. If they do not match, no marking is made. In this round of comparison, since the second alcohol test record does not represent the same face as Record 1, no marking is made. After this round, the relevance markings in the record table remain as before. Figure 4 As shown.

[0068] Once all required alcohol test records have been compared in one round, the comparison process ends. New alcohol test records will be compared again as they arrive. Understandably, when a new alcohol test record arrives, it only needs to be compared with each of the previous records individually; there's no need to perform cross-comparisons between previous records, thus saving comparison time.

[0069] In the initial labeling process described above, face comparison utilizes face recognition software or algorithms. A face recognition algorithm, after detecting a face and locating key facial feature points, can crop out the main facial region, preprocess it, and then feed it into the backend recognition algorithm. The recognition algorithm extracts facial features and compares them with known faces, determining whether the two faces are the same or different based on their similarity. The known faces can be the facial photos in the comparison records mentioned above. The face recognition software or algorithms used in this invention are existing technologies; any software or algorithm capable of face recognition using two photos (i.e., the facial photo in the comparison record and the photo being compared) or two videos can be used.

[0070] After the initial marking is completed, final marking and alarms need to be generated based on the comparison results. The method is as follows:

[0071] If all associated comparison records and the faces in all the comparison records are identified as the same face, it indicates that these alcohol test records are related. In this case, a final labeling is needed based on factors such as the correlation between the alcohol test results and the correlation between the test times to determine whether their correlation is normal.

[0072] (1) If the two alcohol test records initially marked as related are a rapid screening alcohol test record and an active breath alcohol test record, and the rapid screening alcohol test is performed first and the active breath alcohol test is performed later, and the time interval between the two tests does not exceed the specified value, then the two alcohol test records are normally related, and the corresponding record number should be marked in the correlation column of each record. If the time interval between the two tests exceeds the specified value, then the two records are abnormally related, and the correlation column of each record should be marked as "abnormal".

[0073] (2) If the two alcohol test records initially marked as related are the rapid screening alcohol test record and the active breath alcohol test record, and the active breath alcohol test was performed first and the rapid screening alcohol test was performed later, it indicates that the correlation between the two alcohol test records is abnormal, and the correlation column of each alcohol test record should be marked as "abnormal".

[0074] (3) If two or more alcohol test records initially marked as related are active breath alcohol test records, then the correlation column of these alcohol test records should all be marked as "abnormal".

[0075] (4) If one positive rapid screening alcohol test record can be associated with one or more active breath alcohol test records among two or more alcohol test records initially marked as related, then the association column of these alcohol test records should be marked as “abnormal”.

[0076] (5) If one of the two or more alcohol test records initially marked as related can be linked to an active breath alcohol test record with a result of zero, then the correlation column of these two alcohol test records should be marked as “abnormal”.

[0077] (6) If one of the two alcohol test records initially marked as related can be linked to an active breath alcohol test record with a non-zero alcohol test result, then the correlation column of these two alcohol test records should be marked as "abnormal".

[0078] In rule (1), the interval can be set to half an hour or longer.

[0079] For alcohol test records that are not initially marked as related, the following rules shall be used to determine whether the correlation is normal:

[0080] (1) If a rapid screening alcohol test record with a negative alcohol test result or an active breath alcohol test record does not find a related alcohol test record and the correlation is not marked in the initial marking, then the correlation column of the alcohol test record will not be marked in the final process.

[0081] (2) If the alcohol test result data of the rapid screening alcohol test record is positive, but no related active breath alcohol test record is found according to the face comparison, and no correlation is marked in the preliminary labeling, then the correlation column of the alcohol test record will be marked as "abnormal".

[0082] Of course, corresponding regulations can also be made for other possible situations. For example, if two alcohol test records initially marked as related are both quick screening alcohol test records, or if three alcohol test records are initially marked as related, but two of them are quick screening alcohol test records, etc. Whether these situations should be marked as normal or abnormal needs to be decided according to the needs.

[0083] The above rules may also have overlapping application issues. For example, regarding rule "(1) If two alcohol test records initially marked as related are a rapid screening alcohol test record and an active breath alcohol test record, and the rapid screening alcohol test is performed first and the active breath alcohol test is performed later, and the time interval between the two tests does not exceed the specified value, then it means that the two alcohol test records are normally related, and the corresponding record number should be marked in the correlation column of each alcohol test record. If the time interval between the two tests exceeds the specified value, then it means that the two alcohol test records are abnormally related, and the correlation column of each alcohol test record should be marked as "abnormal". This may conflict with rule "(5) If among two or more alcohol test records initially marked as related, a positive rapid screening alcohol test record can be associated with an active breath alcohol test record with an alcohol test result of zero, then these two alcohol test records are considered to be related. In the correlation column of the test record, it should be marked as "abnormal" or "overlapping". That is, if two alcohol test records initially marked as related first undergo a rapid screening alcohol test and then an active breath alcohol test, then according to rule (1), the correlation should be judged as normal and marked with the corresponding record number. However, if the alcohol test result data of the rapid screening alcohol test record is positive and the alcohol test result data of the active breath alcohol test record is zero, then according to rule (5), the correlation will be judged as abnormal. In this case, the final judgment result should be abnormal correlation. That is, in a certain judgment, if multiple rules are applied at the same time, the final judgment basis is: if all applicable rules judge the correlation as normal, then the correlation of these alcohol test records is normal; if one applicable rule judges the correlation as abnormal, then the correlation of these alcohol test records is abnormal.

[0084] right Figure 4 The preliminary labeling results shown are followed by a final labeling record table using the methods described above. Figure 5 As shown in the diagram, records 6 and 5 are two voluntary breathalyzer tests conducted on the same person within a few minutes of each other. Therefore, the relevance column for records 5 and 6 is ultimately marked as "abnormal." Record 4 shows a positive result from a quick screening alcohol test, but no other voluntary breathalyzer test with the same face was found among all alcohol test records. Therefore, this record is marked as "abnormal." Record 1, being a voluntary breathalyzer test, did not have a matching quick screening alcohol test found, but since this is normal, no relevance column is marked for it.

[0085] Alcohol test records that are ultimately marked as "abnormal" in terms of relevance can be displayed in red as a warning.

[0086] It is understood that two alcohol test records may be related or unrelated. In other words, even a lack of relevance can be considered a form of relevance; that is, relevance includes both "related" and "unrelated" scenarios. However, regardless of whether they are related or not, in this invention, they can be further divided into two situations: normal relevance and abnormal relevance. That is, related alcohol test records may exhibit both normal and abnormal relevance, and unrelated alcohol test records may also be considered to exhibit both normal and abnormal relevance.

[0087] Additionally, for alcohol test records that have been finally marked as related and have normal correlation (marked with the corresponding record number), and for alcohol test records with abnormal correlation (marked as "abnormal"), clicking the "Relevance" column will display two or more alcohol test records related to that record in a pop-up window. However, for alcohol test records with positive results from quick screening but no related active breathalyzer test records found, no related alcohol test records will be displayed. Furthermore, for alcohol test records that are deemed to have normal correlation and therefore not marked, no related alcohol test records will be displayed.

[0088] To reduce the workload of comparison, a comparison time range can be set. For example, each alcohol test record can only be compared with alcohol test records within the previous T hours. If T is set to 24 hours, then... Figure 2 In the record table shown, the 6th alcohol test record is only compared with data from within the same day (i.e., record 5), and not with the previous 4 alcohol test records, thus shortening the comparison time. Generally, the time interval between a quick screening alcohol test and an active breathalyzer test does not exceed 30 minutes; therefore, T can be set to 2 hours. In this way, although the 5th and 6th alcohol test records do not contain identity or vehicle information, and names cannot be used for identification due to potential duplication, facial recognition reveals a correlation between the 5th and 6th alcohol test records. Furthermore, since both are active breathalyzer tests conducted close together, marking these two records as "abnormal" can prevent improper operation. By limiting the time range, the amount of data to be compared can be relatively reduced, improving comparison efficiency.

[0089] It is understood that the preliminary and final marking methods described above are only for illustrative purposes and can be implemented together in a single algorithm in practical applications, without the need for separate preliminary and final marking steps. The alignment process used in this preferred embodiment can relatively reduce alignment time and improve alignment efficiency.

[0090] In summary, the method for quickly linking breathalyzer test records with drunk driving test records of this invention can standardize the management of drunk driving investigations and prevent irregular operations during drunk driving investigations, such as preventing: 1. Conducting a rapid breathalyzer test first, and if the result is positive, not conducting a breathalyzer test; 2. If the rapid breathalyzer test result is positive, and a breathalyzer test is also conducted, but the result exceeds the penalty limit for drunk driving, the person being tested delays the process until the blood alcohol content decreases before conducting multiple breathalyzer tests, using the lowered result as the basis for punishment, thereby reducing or waiving the penalty; 3. If the rapid breathalyzer test result is positive, having a third party take the blame for the breathalyzer test to evade punishment.

[0091] Furthermore, both rapid screening alcohol detectors and breathalyzers can malfunction or be operated improperly during use, leading to erroneous test results. This can easily cause disputes, such as: 1. If the rapid screening alcohol test result is positive but the breathalyzer result is zero when testing the same person, it could be that either the rapid screening alcohol detector or the breathalyzer is malfunctioning; 2. If the rapid screening alcohol test result is negative but the active breathalyzer result is greater than zero when testing the same person, it could be that either the rapid screening alcohol detector or the breathalyzer is malfunctioning. The method of correlating rapid screening alcohol test results with active breathalyzer results in this invention can provide objective, accurate, and rapid evidence for such disputes, facilitating a fair and just resolution.

[0092] As described above, those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts of this invention, and all such changes and modifications should fall within the protection scope of the appended claims of this invention.

Claims

1. A method for rapidly correlating alcohol test records with active breath alcohol test records, characterized in that, include: Step 10: When conducting a rapid screening alcohol test or active breath alcohol test on the subject, simultaneously take a facial photo of the subject that can be used for facial recognition. Step 20: Upload the alcohol test results and corresponding facial photos to the drunk driving management system database; Step 30: Each alcohol test result record and its corresponding face photo in the database are considered as one alcohol test record in the database. Within the preset range of alcohol test records, all alcohol test records within the range that are identified as the same person based on the face photo recognition results are judged to be related to each alcohol test record. Other alcohol test records within the range are judged to be unrelated to each alcohol test record. Step 40: According to the preset rules, for all alcohol test records that are related within the range, determine whether each alcohol test record is abnormal by combining the alcohol test results contained in each alcohol test record. For alcohol test records that are not related within the range, determine whether each alcohol test record is abnormal by combining the alcohol test results of each alcohol test record.

2. The association method as described in claim 1, characterized in that, The alcohol test result record includes the alcohol test type, alcohol test result data, and test time.

3. The association method as described in claim 1, characterized in that, The rapid alcohol detection device for quickly screening a person for alcohol testing and the breath alcohol detection device for actively exhaling alcohol testing each have an alcohol detection module, a camera, and a communication module. The alcohol detection module is used to perform the corresponding alcohol test, the camera is used to take a facial photo of the person being tested that can be used for facial recognition while conducting the alcohol test, and the communication module is used to transmit the alcohol test result provided by the alcohol detection module and the corresponding facial photo of the person being tested provided by the camera to the database of the drunk driving management system.

4. The association method as described in claim 1, characterized in that, It also includes step 50, issuing an alarm for alcohol test records that are judged to be abnormal.

5. The association method as described in claim 2, characterized in that, The preset alcohol test recording range is limited by the detection time of the alcohol test results recording.

6. The association method as described in claim 5, characterized in that, The preset alcohol test record range is alcohol test records within a test time of 2 hours to 24 hours.

7. The association method as described in claim 2, characterized in that, The server of the drunk driving management system is equipped with facial recognition software and algorithms. When running, the software and algorithms can compare the facial photos in each alcohol test record in the drunk driving management system database one by one. The current alcohol test record to be compared is called the comparison record, and the other alcohol test records to be compared are called the comparison records. The drunk driving management system determines whether there is a correlation between the comparison record and the comparison record based on the comparison results.

8. The association method as described in claim 7, characterized in that, The one-to-one comparison process is as follows: First, take the latest alcohol test record within the preset range of the database as the comparison record, and compare it with each of the previous alcohol test records. When the comparison shows the same face, it is determined that there is a correlation between the comparison record and the comparison record. If the comparison does not show the same face, it is determined that there is no correlation between the comparison record and the comparison record. Then, take the previous alcohol test record within the preset range of the database as the comparison record and compare it with each of the alcohol test records before it. If the comparison shows the same face, it is determined that there is a correlation between the comparison record and the comparison record. If the comparison does not show the same face, it is determined that there is no correlation between the comparison record and the comparison record. In this manner, the alcohol test record preceding the previous comparison record is taken as the current comparison record, and compared with each of the preceding alcohol test records. Similarly, it is determined whether there is a correlation between the comparison record and the comparison record, until the first alcohol test record is taken as the current comparison record, thus completing this one-to-one comparison.

9. The association method as described in claim 8, characterized in that, Once all the alcohol test records that need to be compared have been compared once, the comparison ends, and a new comparison will be performed when a new alcohol test record arrives.

10. The association method as described in claim 9, characterized in that, When a new alcohol test record is received, only the new alcohol test record is used as the comparison record and compared with all the previous alcohol test records once. Instead of comparing the previous alcohol test records with each other, the comparison time is saved.

(2) If the two alcohol test records that are determined to be related are a rapid screening alcohol test record and an active breath alcohol test record, and the active breath alcohol test was performed first and the rapid screening alcohol test was performed later, then the correlation between the two alcohol test records is abnormal. (3) If two or more alcohol test records that are judged to be related are active breath alcohol test records, then the correlation between these alcohol test records is abnormal. (4) If one of the two or more alcohol test records that are identified as related is associated with one or more active breath alcohol test records, then the association between these alcohol test records is abnormal. (5) If one of the two or more alcohol test records that are determined to be related is a rapid screening alcohol test record with a positive alcohol test result, and is related to an active breath alcohol test record with a zero alcohol test result, then the correlation between these two alcohol test records is abnormal. (6) If one of the two alcohol test records that are determined to be related is a rapid screening alcohol test record with a negative alcohol test result, and is related to an active breath alcohol test record with a non-zero alcohol test result, then the correlation between these two alcohol test records is abnormal. (7) If a rapid screening of alcohol test records with a negative result or an active breath alcohol test record does not find a related alcohol test record, then the correlation of the alcohol test record is normal. (8) If the alcohol test result data of the rapid screening alcohol test record is positive, but no related active breath alcohol test record is found according to the face comparison, then the correlation of the alcohol test record is abnormal.
