Description

Technical Field

[0001] The present invention relates to the technical field of traffic safety, and in particular to a device that automatically detects drunk driving and connects to a law enforcement system for automatic alarm. Background Art

[0002] With the continuous increase in the number of cars, the problem of drunk driving has become increasingly serious and has become one of the main causes of traffic accidents. The traditional method of drunk driving detection mainly relies on the on-site breath alcohol detector of the traffic police. Although this method is effective, it has problems such as low detection efficiency, limited coverage, and difficulty in real-time monitoring. In addition, although some existing drunk driving detection devices can automatically detect alcohol concentration, they lack direct connection with the law enforcement system, resulting in the inability to upload the test results in time and unable to form effective deterrence and supervision.

[0003] In existing patents, for example, a laser drunk driving detection device with patent number CN118781820A, although it realizes automatic detection of alcohol concentration, does not provide a direct connection function with the law enforcement system, and lacks monitoring means for drivers who have not left the cab. In addition, a drunk driving warning system and vehicle with patent number CN109760515B, although it can remotely monitor the alcohol status of the driver, the device is bulky and inconvenient to install, and it fails to realize instant upload and alarm of the detection results. Summary of the invention

[0004] The technical problems to be solved by the present invention are: (1) improving the accuracy and timeliness of drunk driving detection and realizing real-time monitoring; (2) realizing direct connection between the detection results and the law enforcement system to ensure timely data upload; (3) monitoring whether the driver leaves the cab to prevent evasion of detection; (4) the device is small in size, easy to install, and suitable for various types of vehicles.

[0005] In order to solve the above technical problems, the present invention provides a technical solution: a device for automatically detecting drunk driving and connecting to a law enforcement system for automatic alarm, comprising:

[0006] The shell is a hard rectangular structure;

[0007] The gas detection device is embedded in the front of the housing. The main body of the gas detection device is an alcohol detector. The alcohol detector has a built-in electrochemical sensor.

[0010] QR code, which is printed on the front of the housing and located between the normal light and the warning light. The QR code can be connected to the law enforcement system by scanning the QR code with a mobile device. The device sends the detection results to the law enforcement system through the built-in wireless signal transceiver;

[0011] The camera is embedded in the front of the shell and located above the QR code. When the driver's gas test results are unqualified, the alarm light will be triggered to light up. If the driver does not leave the cab within three minutes, the camera will automatically take pictures and upload them to the law enforcement system.

[0012] Furthermore, a main control device is built into the shell.

[0025] (6) Main control device: The main control device is built into the shell and consists of a PCB board with a CPU main control chip, a wireless signal transceiver, a power supply battery and an auxiliary control circuit. The main control device is connected to the gas detection device, normal light, alarm light, camera and other components through signal lines to achieve electrical control and data processing of the entire device.

[0026] The functions of this device include:

[0027] (1) Alcohol concentration detection: The alcohol concentration in the cab is detected in real time through an electrochemical sensor with high accuracy and fast response speed.

[0028] (2) Alarm and upload: When the alcohol concentration reaches or exceeds the alarm standard, the alarm light will light up and the test results will be uploaded to the law enforcement system via a wireless signal transceiver.

[0029] (3) Monitoring and photography: When the driver’s alcohol test result is unqualified and he / she does not leave the cab within three minutes, the camera automatically starts the photography function, records the driver’s image information, and uploads it to the law enforcement system.

[0030] (4) Data management and analysis: The law enforcement system receives and stores test results and photo information to facilitate subsequent data management and analysis.

[0031] In terms of electrical connection, the main control device is electrically connected to the gas detection device, normal light, warning light, camera and other components through signal lines to achieve data transmission and control command transmission.

An adhesive fixing sticker is provided on the back of the shell, which fixes the device in a suitable position in the cab by sticking to ensure that the device is stable and not easy to fall off.

[0032] Embodiment 2

[0033] Based on the first embodiment, Figure 1 As shown in the figure, when the device is started, the gas detection device starts to detect the alcohol concentration in the cab in real time. If the alcohol concentration does not reach the alarm standard, the normal light will light up, indicating that the test result is qualified; if the alcohol concentration reaches or exceeds the alarm standard, the alarm light will light up, and the main control device will upload the test result to the law enforcement system through the wireless signal transceiver. In addition, if the driver's alcohol test result is unqualified and he does not leave the cab within three minutes, the camera will automatically start the photo function and upload the photo to the law enforcement system. The law enforcement system receives and stores the test results and photo information to provide support for subsequent data management and analysis.

[0034] It can be seen that this solution provides an efficient, accurate and intelligent drunk driving detection device, which effectively curbs the occurrence of drunk driving and ensures road traffic safety through functions such as real-time monitoring of alcohol concentration, instant alarm, escape monitoring and intelligent management.

[0035] Embodiment 3

[0036] Based on the second embodiment, Figure 1As shown, the working principle of the device of the present invention is based on electrochemical sensing technology and wireless communication technology. The device detects the alcohol concentration in the cab in real time through an electrochemical sensor. When the alcohol concentration reaches or exceeds the preset alarm standard, the alarm mechanism is triggered, and the detection result is uploaded to the law enforcement system through wireless communication technology. At the same time, the device also has the function of monitoring whether the driver has left the cab. When the driver's alcohol test result is unqualified and he does not leave within the specified time, the camera will automatically start the photo function, record the driver's image information, and upload it to the law enforcement system.

[0037] The specific steps are as follows:

[0038] (1) Alcohol concentration detection: The electrochemical sensor reacts with alcohol gas through the sensitive electrode to generate a weak current. The intensity of the current is proportional to the alcohol concentration. By measuring the current intensity, the specific concentration of alcohol can be calculated.

[0039] (2) Data processing and judgment: The main control device receives the current signal output by the electrochemical sensor, and obtains the alcohol concentration value through internal circuit processing and algorithm calculation. The alcohol concentration value is compared with the preset alarm standard. If it reaches or exceeds the alarm standard, the alarm mechanism is triggered.

[0040] (3) Alarm and upload: When the alcohol concentration reaches the alarm standard, the main control device controls the alarm light to light up, and uploads the test results including alcohol concentration value, test time, device number and other information to the law enforcement system through the wireless signal transceiver. The law enforcement system receives and stores this information for subsequent processing and analysis.

[0041] (4) Monitoring and photography: If the driver's alcohol test result is unqualified and he does not leave the cab within the specified time, such as within three minutes, the main control device will trigger the camera's photography function. The camera captures the image information in the cab and uploads it to the law enforcement system through a wireless signal transceiver. The law enforcement system receives and stores this image information as evidence of drunk driving.

[0042] Embodiment 4

[0043] Based on the third embodiment, Figure 1 As shown, in the specific implementation of this scheme, the housing 1 is made of high-strength, corrosion-resistant ABS plastic or aluminum alloy material, and is in the shape of a hard rectangular structure, which is easy to install and carry. An opening is provided on the front of the housing for installing a gas detection device, a normal light, an alarm light, a QR code and a camera; an adhesive fixing sticker is provided on the back to facilitate fixing the device in a suitable position in the cab.

[0044] The gas detection device 2 has a built-in electrochemical sensor, which generates a weak current through an electrochemical reaction between the sensitive electrode and the alcohol gas. The current intensity is proportional to the alcohol concentration, and the specific concentration of the alcohol can be calculated by measuring the current intensity. The gas detection device also includes a signal processing circuit and an interface circuit, which are used to convert the current signal into a digital signal and transmit it to the main control device.

[0045] The normal light 3 and the warning light 4 both use LED lights as light sources, and are used to display the qualified and unqualified test results respectively. The normal light uses a green LED light, which lights up when the alcohol concentration does not reach the alarm standard; the warning light uses a red LED light, which lights up when the alcohol concentration reaches or exceeds the alarm standard.

[0046] The QR code 5 is printed on the front of the housing and contains the unique identification of the device and information for connecting to the law enforcement system. Scanning the QR code with a mobile device such as a smartphone can connect to the law enforcement system and enable instant upload of the test results.

[0047] The camera 6 uses a high-definition wide-angle lens and has a night vision function. When the driver's alcohol test result is unqualified and he does not leave the cab within the specified time, the camera automatically starts the photo function to record the driver's image information.

[0048] The main control device has a built-in CPU main control chip, wireless signal transceiver, power supply battery and auxiliary control circuit. The CPU main control chip is responsible for receiving data from the gas detection device, controlling the light display, triggering alarms and camera photography, etc. The wireless signal transceiver is used for data transmission and communication with the law enforcement system; the power supply battery provides power support for the entire device.

[0049] In terms of installation and debugging of this device, install the device in a suitable position in the cab to ensure that the gas detection device can fully contact the air in the cab; at the same time, ensure that the camera can clearly capture the facial features of the driver. Connect the power supply battery of the device to the vehicle power supply to ensure that the device can continue to work. If the device uses a rechargeable battery, it needs to be charged regularly to keep the battery sufficient. After the device is installed, perform a functional test. By blowing gas containing different concentrations of alcohol into the gas detection device, test whether the alarm function and upload function of the device are normal. At the same time, test whether the camera function and upload function of the camera are accurate and reliable. According to actual needs, set the alarm standard value, photo time and other parameters of the device. Ensure that the device can be flexibly adjusted according to the laws and regulations and actual needs of different regions.
