[0025] Figure 7It is the main view and side view of the driving recorder. The driving recorder includes a camera, a storage device, a GPS positioning device, and an alcohol detection device, which are used to record the vehicle trajectory, compare the driver's facial data, and detect the driver's alcohol content. The front view area of ​​the driving recorder is 188mm long and 60mm wide. The rear embedded part is 164.85mm long and 50mm wide. The main parts of the driving recorder are the driving recorder MIC microphone 5, the display screen 6, the identity card slot 7, the function button 8, and the external port 9. The identity card slot 7 is used to insert the identity card, which is mainly used to provide vehicle positioning services and vehicle trajectory information. The external port 9 has the function of connecting an external camera and a vehicle-mounted alcohol detection device.

[0026] The driving recorder is equipped with two cameras, a 1T hard drive, a GPS positioning device, a 4G communication device (4G module), and an alcohol detection device. When the driver is driving the vehicle, the camera will collect the driver's facial data and transmit it back to the cloud server for comparison and analysis with the applicant's facial data. If the driver's information is inconsistent with the applicant's information, the cloud server will send the abnormal data comparison information to the administrator's backend, generate a car use abnormality record, and notify the administrator to handle it. The driver cannot use the car at this time. At the same time, the in-car breath alcohol detection device (alcohol detection module) will detect whether the driver is driving under the influence of alcohol. If the driver fails to pass one of the facial recognition and alcohol detection, he cannot start the vehicle.

[0028] As mentioned above, in the management system, the user terminal, cloud platform server, driving recorder, key box, face recognition module and alcohol detection module, 4G / 5G module and other components and their connection control technologies are all existing technologies, see "A data box for intelligent key management, publication number CN217904816U Chinese utility model", "Car key item management system device based on alcohol detection and identity authentication, publication number CN215993253U Chinese utility model", "In-vehicle drunk driving comprehensive detection system for unit vehicles based on multi-source information fusion, announcement number CN113370786B Chinese invention", and the use of PONY (electronic) 794S driving recorder, etc., will not be repeated here; the improvement of the present application lies in the arrangement of a key box and a key box mounting structure in the box, and the arrangement and connection of components such as the user terminal and the cloud platform server. The user submits a car application on the mobile car key management system, and the administrator approves and grants the user car use rights. The user scans his face through the face recognition device on the key box to obtain the user's identity information and compare it with the face database. After the face recognition is passed, the breath alcohol detection device is used to detect whether the person has been drinking. After the alcohol test is passed, the key control program opens the key ring door and the user obtains the key. The user inserts the car key into the car keyhole, and the camera at the driving recorder captures the driver's image and uploads it to the cloud platform for face recognition comparison to see if he has driving rights. After the face recognition is passed, the breath alcohol detection device is used to detect whether he has been drinking. During this process, the face recognition system and the alcohol detection device continue to perform face comparison and alcohol detection. If there is a discrepancy, the car use abnormality is reported, and the GPS driving trajectory is recorded throughout the car use process. When returning the car key after the car is used, the key box is opened through face recognition comparison, and the car key return is completed; of course, an electric lock for the box door can also be added. After the comparison is successful, the box door can be opened at the same time to return the car.

[0029] The utility model adopts facial recognition and alcohol detection to double-verify the cabinet opening, and is equipped with a power interface. When lending out keys, the user scans his face in front of the device. Under the condition of successful facial matching, the alcohol module starts detection, and the user blows alcohol into the alcohol blowing hole. The key box control program determines whether the alcohol content exceeds the standard. If it does not exceed the standard, the buckle is opened, and the user obtains the car key; when returning the key, the authorized person passes the facial recognition, and the key box control program obtains the current lock state, opens the empty lock, and the user returns the key. Intelligently combining existing technologies such as password technology, RFID technology, and biometrics, the intelligent management key box has a complete automation function, one-click application and one-click return.

[0030] The driving recorder of this utility model is connected to an external vehicle power supply. It records the vehicle driving status information and driver information during the use of the vehicle. It uses a camera to capture the driver's face in real time, and detects alcohol during driving. The data is transmitted to the cloud platform through the vehicle-mounted 4G communication equipment and the operator's base station to compare whether the driver has the right to drive. If the driver does not have the right, the mobile terminal and PC terminal will issue an abnormal alarm to inform the management personnel to handle it; the GPS positioning device obtains the vehicle location information through the satellite and transmits it to the cloud platform in real time. Combining existing image recognition technology, GPS positioning technology and 4G communication technology, it can realize the real-time tracking of the vehicle, that is, the real-time monitoring of the car key use process.

[0031] The mobile terminal and PC terminal of the utility model are both implemented with existing software, and can apply for car use online. The management personnel review the applicant's authority. After authorization, the car user can go to the key box to verify and obtain the key, and can view the application for car use, car use records, car use alarms, and manage and approve today's application and pending my approval. From the perspective of car key management, through the intelligent management of key boxes and driving recorder hardware, car application, prior approval, in-process supervision, and post-event management are realized, achieving the goal of intelligent, standardized, and scientific management of the entire process of car key use.

[0032] As mentioned above, the intelligent key box management device includes a face recognition module, an alcohol detection module, and a key management module. The face recognition module uses a face recognition system to meet the face recognition accuracy requirements, captures facial feature data and compares it with the face recognition database, verifies whether the user has the right to use the key, avoids impersonation by others, simplifies the recognition process, and improves work efficiency; the alcohol detection module uses a gas-sensitive alcohol detection sensor and an infrared distance sensor detector to meet the basic requirements of drunk driving detection, and uses the collected data through the alcohol detection system to obtain an accurate alcohol concentration to determine whether the user meets the driving conditions. The credibility of the alcohol detection result is high; the key management module uses a key status indicator light to observe the key taking situation, and only users who pass face recognition and alcohol detection can take the key. The key management security is high, reducing the influence of human factors. In general, there is no right to take the car key without authorization, and it is forbidden to take the car key if the alcohol test fails. During the use of the car key, whether the car is drunk driving is monitored and the record is uploaded. After that, the drunk driving behavior is investigated through the drunk driving record, which effectively reduces the occurrence of drunk driving. Even more, this application can be further expanded and combined with the vehicle starting system (which is an existing technology). The engine can be started and the vehicle can be operated for a long time only after the test is qualified. Otherwise, it will not be able to start or will be prompted to pull over and shut down after a short time. This can effectively prevent the occurrence of drunk driving.

[0033] The driving recorder device uses a camera, a GPS positioning module, and an alcohol detection device. It monitors the entire process of vehicle use through facial comparison, alcohol detection and positioning systems, such as whether the driver is driving himself, whether he is driving under the influence of alcohol, whether the vehicle is used beyond the scope of use, and other abnormal situations. The vehicle use process information is transmitted to the cloud platform through the 4G communication module, and the entire process of car key use is scientifically monitored.

[0034] The mobile terminal has the functions of vehicle management, approval, and information viewing. The functions of the mobile terminal are consistent with those of the management PC terminal. The vehicle trajectory is displayed in real time through the vehicle positioning system, and reports on when, who, and how long the vehicle was used can be queried. Messages are reminded in real time, and vehicle usage records can be traced.

[0035] The utility model starts from the perspective of car key management and realizes the whole process management of car use through car application, prior approval, in-process supervision and post-event management.
