[0046] The present invention will be further described below with reference to the accompanying drawings and in combination with preferred embodiments. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0047] It should be noted that the directional terms such as left, right, up, down, top, and bottom in this embodiment are merely relative concepts, or are based on the normal use status of the product, and should not be considered as restrictive.

[0048] Existing breathalyzers are mainly divided into two types: ordinary fast-test breathalyzers and active precise-test breathalyzers. Generally, the quick-test and precise-test functions are designed separately in two separate devices, or both functions are superimposed on a single device. Furthermore, considering the current breathalyzer usage scenarios and the information correlation with the network backend system, the following main defects or deficiencies exist:

[0049] 1. Use and management maintenance is inconvenient. When used on site, two sets of equipment, fast test alcohol detector and accurate test alcohol detector, must be used in cooperation, the fast test alcohol detector is detected, and then the accurate test alcohol detector is used, which leads to inconvenient operation and use; at the same time, the two sets of equipment need to be managed and maintained daily, so it is very inconvenient to manage and maintain the alcohol detection equipment.

[0050] 2. The cost of single machine and management and maintenance is high. Due to the existence of two sets of equipment, the cost of single machine and management and maintenance is greatly increased. Even if two sets of equipment are integrated together, the current design is still separated in appearance and function device design, and two sets of key core devices such as air pump and alcohol sensor are still needed, so the cost cannot be obviously reduced.

[0051] 3. The detection data and the background system cooperation and correlation are insufficient, and it is easy to fake. The design of the alcohol detection instrument terminal device emphasizes the performance of the individual, and cannot be cooperated with the system function of the background system. In addition, the alcohol detection instrument terminal and the background system management only stop at data transmission, the correlation is insufficient, the detection data and the detection object cannot be uniquely matched, and data falsification and cheating are easy to bring.

[0052] Therefore, in order to solve the above defects or deficiencies, the embodiment of the present application provides an alcohol detection recorder and system to achieve the following purposes:

[0053] 1. The integrated design of fast test alcohol detector, accurate test alcohol detector and law enforcement recorder is realized, and the use and management and maintenance of the equipment are facilitated.

[0054] 2. On the basis of integrated design, two sets of fast test and accurate test equipment are integrated, the key core devices are shared, and the cost of the equipment is reduced.

[0082] The information association module integrates the alcohol detection test data and the alcohol detection information data into associated data, and uploads the associated data to the background system through the wireless image transmission module.

[0083] The alcohol detection recorder and system proposed in the embodiment of the application is a device combining an alcohol detection instrument and a law enforcement recorder, and is a product system that transmits, analyzes and manages relevant data in cooperation with a software background system.

[0084] Its main application field is to detect the alcohol of a vehicle driver in traffic law enforcement to determine whether there is a violation such as driving after drinking, and the device has the function of a law enforcement recorder and integrates a camera, which can perform face recognition on the detected object during alcohol detection and record the audio and video of the whole detection process for evidence, and associate the test data and the information of the detected object through the background system.

[0085] Through the comprehensive system of the device and the background system, the purpose of eliminating alcohol detection data fraud and cheating is achieved.

[0086] The embodiment of the application specifically includes the following parts:

[0087] 1. ID form design:

[0088] In the ID form design, the embodiment of the application integrates the fast test and accurate test functions of the alcohol detection instrument to realize integrated design.

[0089] At the same time, the function of the law enforcement recorder is also integrated on the device, and the law enforcement recorder has the functions of audio and video recording and 4G / 5G image transmission, which can realize the on-site evidence collection of law enforcement audio and video and the function of uploading alcohol detection data to the background system to associate with the background system. As shown in Figure 1 The alcohol detection recorder and system proposed in the embodiment of the application realizes the two-in-one of fast test and accurate test, and the two-in-one of alcohol detection instrument and law enforcement recorder, and the components include a camera 3, so that the audio and video evidence of the alcohol detection process can be realized.

[0090] 2. Hardware integrated design:

[0091] Based on the integrated form design, the fast test alcohol detection instrument and the accurate test alcohol detection instrument are respectively designed as two sets of independent air pumps, alcohol sensors and other key core devices, and the fast test alcohol detection instrument and the accurate test alcohol detection instrument are combined for common design in the embodiment, and the principle structure of the fast test alcohol detection instrument is as shown in Figure 2aAs shown, its working process: air flow through the air inlet 1 --- flow sensor 4 --- alcohol sensor 5 --- air pump 6 --- alcohol sensor 5 --- exhaust port 7 discharge. The principle structure of the accurate alcohol detector is as shown in Figure 2b As shown, its working process: air flow through the air inlet 1 --- alcohol sensor 5 --- air pump 6 --- exhaust port 7 discharge. The principle structure of the alcohol detector of the embodiment is as shown in Figure 2c As shown, the fast discharge + accurate integrated alcohol detector after hardware integration has only one set of flow sensor 4, alcohol sensor 5 and air pump 6. At the same time, the air inlet 1 is set to be compatible with the structure of the mouthpiece 2, and a new exhaust port 7 and a switching switch 8 are designed on the air pump 6.

[0092] Its working mode includes fast discharge detection mode and accurate detection mode. In the fast discharge detection mode, the working process is as follows: the menu selection of the machine is set to fast discharge detection mode, and the software will automatically open the switching switch 8; the fast discharge test air flow path is as shown in Figure 3a As shown, the air flow through the air inlet 1 --- alcohol sensor 5 --- air pump 6 --- exhaust port 7 discharge, completing the fast discharge detection; in the accurate detection mode, the working process is as follows: the menu selection of the machine is set to accurate detection mode, and the mouthpiece 2 is inserted into the air inlet 1, at this time, the software will automatically close the switching switch 8; the accurate test air flow path is as shown in Figure 3b As shown, the air flow through the air inlet 1 --- flow sensor 4 --- alcohol sensor 5 --- air pump 6 --- alcohol sensor 5 --- exhaust port 7 discharge, thereby completing the accurate detection.

[0093] The switching switch 8 changes the opening and closing state of the switching switch according to the selection of the fast discharge detection mode and the accurate detection mode.

[0094] The functions of the flow sensor are as follows:

[0095] 1. In the accurate detection, the air flow enters the flow sensor, and when the sensor detects that the air flow reaches a certain air pressure, the air pump starts to work to draw the air flow through the alcohol sensor into the air pump.

[0096] 2. In the fast discharge detection, the switching switch is opened, the air flow passes through the air inlet --- alcohol sensor --- air pump --- exhaust port to discharge, completing the fast discharge detection. In the accurate detection, the mouthpiece is inserted into the air inlet, and the switching switch is closed, the air flow passes through the air inlet --- alcohol sensor --- air pump --- alcohol sensor --- exhaust port to discharge, thereby completing the accurate detection.

[0097] The design scheme realizes the functions of fast discharge detection and accurate test, reduces one set of core devices, and thus achieves the purpose of reducing cost.

[0098] In addition, due to the integrated sharing of core devices, the use of accurate detection quantitative gas pumps and gas path design, when doing fast exhaust test, the device actually extracts and detects the detection gas multiple times, thereby greatly improving the accuracy of the fast exhaust test data.

[0099] 3. System association design:

[0100] Through ID form integrated design and hardware integrated design, the wine detection recorder proposed in the embodiment has the functions of wine detection recorder (fast exhaust test, accurate test) and law enforcement recorder (video and audio recording, 4G / 5G / wireless image transmission). So, the device terminal and the background system are associated, as shown in Figure 4 The scheme flow of the associated design is as follows:

[0101] A1, the wine detection recorder starts, that is, the device association (device number and user information) with the background system is performed, and the device is logged into the background system.

[0102] A2, when the wine detection test starts, the law enforcement recorder will start recording at the same time, and the detection object needs to be face snapped, and the face database module of the background system is associated to do online detection and recognition. If face recognition is unsuccessful, blowing alcohol detection cannot be done; if face recognition is successful, blowing alcohol detection can be further done. In addition, when there is no mobile transmission network signal, the device can also do offline face detection and recognition through the face database of the wine detection recorder itself. In this way, normal use in two scenarios of no mobile transmission network signal and mobile transmission network signal can be met.

[0103] A3, after successful face recognition, the wine detection test process is entered, blowing through the air inlet, at the same time the gas pump works, the gas is sucked into the alcohol sensor, then the detection data is output and displayed on the display screen of the device.

[0104] A4, the wine detection test data is integrated with the wine detection information data to obtain associated data, and is wirelessly uploaded to the background system through the wireless image transmission module, so that the data receiving and saving module receives and saves the data, and manages the data information. The data information management module of the background system includes automatically generating a statistical list of associated data, realizing the unique correspondence between the detection object and the associated data.

[0105] The wireless image transmission module can specifically use 4G / 5G mobile network, the wine detection information data includes: device information, user information using the device, face photo of the detection object, video and audio file of the detection process, etc., the associated data includes: the name of the detection object, wine detection test data, detection time, number of detection device, etc. superimposed on the face photo and video and audio file;

[0106] In addition, the permission encryption module will have permission encryption and log recording processing on the above test data information, and any addition, modification and deletion operation on the test data information needs to have corresponding permission to execute the corresponding operation and be recorded in the log for traceability query.

[0107] In this way, through the above system association design, the behavior of replacing detection, forgery, alteration, replacement of detection data and other fraud and cheating behaviors can be finally eliminated.

[0108] The wine detection recorder and system disclosed in the embodiment realize the combination of the fast wine detection instrument and the accurate wine detection instrument, the combination of the wine detection instrument and the recorder, and the combination of the equipment terminal and the software background system in the aspects of form design, hardware integration design and system association, and achieve the purposes of convenient use and maintenance, saving equipment cost and eliminating detection fraud; and the embodiment has systematic comprehensive functions through the organic combination.

[0109] The embodiment of the application has the following beneficial effects:

[0110] The wine detection recorder and system of the embodiment enhance the effective application in the field of traffic law enforcement.

[0111] Experimental example:

[0112] As described in the ID form design and hardware integration design, the wine detection recorder of the experimental example is an integrated wine detection recorder combining the fast test wine detection instrument, the accurate test wine detection instrument and the law enforcement recorder, and the wine detection recorder of the experimental example has the functions of the wine detection function and the law enforcement recorder function, wherein the wine detection function includes fast test and accurate test.

[0113] The wine detection function of the experimental example is a common design of the key core devices such as the fast test wine detection instrument and the accurate test wine detection instrument, which are respectively independent of two sets of air pumps and alcohol sensors, so that one set of core devices is reduced, the purpose of reducing equipment and management and maintenance cost is achieved, and after the common design, the experimental example can still meet the requirements of fast test and accurate test.

[0114] The law enforcement recorder function of the experimental example is to integrate the related modules of the law enforcement recorder on the wine detection instrument, so as to realize the video and audio evidence of the wine detection process, associate the wine detection test data with the device information, the personnel information using the device, the face photo of the detection object, the video and audio file of the detection process, and eliminate the fraud and cheating of the wine detection data according to the information association.

[0115] The experimental example realizes the above-mentioned organic combination of the systematic comprehensive function.

[0116] The wine detection recorder of the present experimental example, as shown in Figure 5 the drawings, mainly comprises a test air inlet 1, an air outlet 7, a flow sensor 4, an alcohol sensor 5, an air pump 6, a camera 3, a display screen 9, a main control unit 10, a communication transmission unit 11, a power supply unit 12, and the like. Among them, the test air inlet 1 is a compatible design, which can be used independently for blowing when performing a fast discharge test; at the same time, a replaceable blowing nozzle 2 can be inserted into the test air inlet for use in precise testing.

[0117] The flow sensor 4 is controlled by the main control unit 10 to start working when the precise testing mode is selected for precise testing in the present experimental example, and is used to detect the pressure of the gas blown from the test air inlet 1. Further, when the gas pressure meets the threshold required for precise testing, the main control unit 10 will issue an instruction to control the operation of the air pump 6 and the alcohol sensor 5.

[0118] The alcohol sensor 5 is arranged beside the gas path between the test air inlet 1 and the air outlet 7, and is used to detect whether the gas passing through it contains alcohol, as well as the content and concentration of the alcohol contained therein, and correctly output the results.

[0119] The air pump 6 is arranged at the rear end of the alcohol sensor 5, and its function is to quantitatively or continuously extract the gas entering the gas path from the test air inlet, so that the gas uniformly passes through the alcohol sensor 5, so that the alcohol sensor 5 can detect the alcohol content and concentration contained in the gas passing through it.

[0120] Further, a switch 8 is arranged on the air pump 6, and the switch 8 is connected with the air outlet 7. When the precise testing mode is selected for precise testing in the present experimental example, the main control unit 10 controls the switch 8 to be in the closed state, at this time, the air pump 6 quantitatively extracts the gas in the gas path to flow through the alcohol sensor 5, and then returns to flow through the alcohol sensor 5, and then is discharged from the air outlet 7, so as to achieve the purpose of precisely testing the content and concentration of alcohol in the gas.

[0121] When the fast discharge test mode is selected for fast discharge testing in the present experimental example, the main control unit 10 controls the switch 8 to be in the open state, at this time, the air pump 6 continuously extracts the gas in the gas path to flow through the alcohol sensor 5, enters the air pump 6, and then flows through the switch 8 on the air pump which has been opened, and is directly discharged to the air outlet 7. Therefore, the alcohol sensor 5 will be able to quickly judge whether the gas flowing through it contains alcohol, so as to achieve the purpose of fast discharge testing.

[0122] The camera 3 of the experimental example is arranged on the same side of the air inlet 1, and is used for video and audio evidence of the whole process of the wine detection test. Further, before the blowing wine detection test is performed, the camera 3 will first take a face snapshot of the detected object, and compare and identify the face photo with the face library stored in the host control unit 10 of the experimental example (that is, offline identification, used when the communication transmission unit 11 of the experimental example is in no mobile network signal). If the face recognition is successful, the blowing wine detection test workflow is entered, and if the face recognition fails, the test is prohibited.

[0123] The communication transmission unit 11 is arranged inside the experimental example, which has two functions. One is to compare and identify the face library of the background system through the communication transmission unit 11 after taking a face snapshot of the detected object (that is, online identification, used when the communication transmission unit 11 is in no mobile network signal). The second is to upload the information associated with the wine detection test data, device information, personnel information using the device, face photo of the detected object, and video and audio files of the detection process to the platform system through the communication transmission unit 11 after the information is associated, so that the platform end receives and saves the data, and manages the data information.

[0124] The display screen 9 is arranged on the side, which is used for output and display of the wine detection test data, and selection and configuration of related information of the experimental example, such as selection of the wine detection test mode, preview of the wine detection process picture, review of the wine detection video and audio, setting of the recorder local performance, network configuration of the communication transmission unit, etc.
