[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] like Figure 1-4 As shown, a car start control device with alcohol detection function includes a main detection mechanism and a secondary detection mechanism, which are wirelessly connected.

[0019] The main detection mechanism includes a main body 2, a signal line 1, a display screen 3, a button 4, an air outlet 5, and a blowpipe 6. The display screen 3, the button 4, and the blowpipe 6 are located on the same side of the main body 2. The air outlet 5 is connected to the blowpipe 6. One end of the blowpipe 6 is the air outlet. A first alcohol detector is provided between the air outlet 5 and the blowpipe 6. The other end of the blowpipe 6 is connected to the first alcohol detector.

[0020] The main body 2 is equipped with a control unit, which includes a PLC and a wireless signal receiving module.

[0021] The auxiliary detection unit includes a housing 11, inside which are an air inlet pipe 8, a wireless signal transmitting module, and a second alcohol detector. An air inlet is provided on one side of the housing 11, one end of the air inlet pipe 8 is connected to the second alcohol detector, and the other end of the air inlet pipe 8 extends to the air inlet of the housing 11.

[0022] The first alcohol detector, display screen 3, button 4, and wireless signal receiving module are all electrically connected to the PLC. The second alcohol detector is electrically connected to the wireless signal transmitting module, and the wireless signal transmitting module is wirelessly connected to the wireless signal receiving module.

[0023] As a preferred option, to improve the display effect, display screen 3 is an LED display screen.

[0024] Preferably, the housing 11 contains a battery, and the second alcohol detector and the wireless signal transmission module are both electrically connected to the battery.

[0025] As a preferred embodiment, in order to improve the stability of the structure, a number of support rods 7 are provided at the air inlet of the housing 11. The housing 11 is cylindrical, and one of the bottom surfaces of the cylinder is the air inlet, that is, this part is hollow and has no bottom surface. The air inlet pipe 8 is coaxially arranged with the housing 11. Each support rod 7 is evenly arranged around the circumference of the air inlet pipe 8. One end of the support rod 7 is connected to the air inlet pipe 8, and the other end of the support rod 7 is connected to the housing 11.

[0026] Preferably, in order to improve the stability of installation, a clamp 9 is provided on the side of the housing 11 away from the support rod 7, and a spring piece 10 is provided on the inner side of the clamp 9.

[0027] In fact, the first and second alcohol detectors are the same type of alcohol detector. An alcohol detector is an instrument used to detect whether a person has ingested alcohol and how much alcohol has been ingested.

[0028] The functions of a PLC are central control and data processing.

[0029] The battery is used for power supply, and the signal line is directly connected to the car's control system to transmit the start signal.

[0030] The wireless signal transmitting module is mainly used to transmit wireless signals, while the wireless signal receiving module is mainly used to receive wireless signals.

[0031] Here, button 4 is used to adjust the display effects, such as screen brightness.

[0032] Display screen 3 is used to show the alcohol test results and corresponding warning messages, such as "You have reached the legal limit for drunk driving, please do not drive the car".

[0033] When the driver gets into the car, he first blows into the breathalyzer 6. The first alcohol detector will then detect the alcohol content. If the alcohol content exceeds the limit, the car cannot be started. If the alcohol content is within the limit, the PLC will issue a start command, which will be transmitted to the car control system through signal line 1, and the car will be able to start.

[0034] The secondary detection mechanism is mounted on the steering wheel, ideally in the center, and is held in place by a clamp 9 and a spring 10. In practice, it also needs to be forcibly secured to the steering wheel with bolts. During driving, the driver's exhalation and inhalation are forward, creating a blowing effect on the intake pipe 8 of the secondary detection mechanism. The second alcohol detector can be set to a frequency that meets actual testing needs, such as every 10 minutes. The data detected by the second alcohol detector is transmitted wirelessly to a wireless signal receiving module, and then to a PLC. The PLC compares the data with preset values ​​and calculates the result. If the test result indicates excessive alcohol levels, a text warning and a color warning will be displayed on the screen 3, such as the screen turning red. The vehicle's engine control system can also be activated according to preset safety protection mechanisms, such as speed limits or penalty call alarms. Technicians can adapt these settings based on actual conditions, personal safety regulations, and traffic regulations.

[0035] Compared with existing technologies, this car start control device with alcohol detection function achieves active start detection by setting up a main detection mechanism and achieves cyclic passive detection by setting up a secondary detection mechanism. The dual detection method reduces the chance of cheating and improves the accuracy of the detection results.

[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
