The person detection device 10 is used for detecting whether a driver is in a driver seat or not, and transmitting an electric signal representing that the driver is in the driver seat to the main controller 20 when the driver is in the driver seat. The person detection device 10 may be a pressure sensor disposed on the driver seat, and detects whether a driver is present on the driver seat through the pressure sensor; the personnel detecting device 10 can also comprise a human body infrared detecting module which detects the infrared radiation energy of the human body to determine whether a driver is on the driver seat; the person detection apparatus 10 may further include a voice recognition module, and determine whether a driver is present in the driver seat through voice information received by the voice recognition module. Of course, the passenger detecting device 10 is not limited to this, and the passenger detecting device 10 may be another detecting device, for example, a passenger detecting device 10 configured by a spring, which detects whether or not a driver is present in a driver seat by triggering a change in an electric signal of a circuit according to a vibration of a spring caused by a vibration of a vehicle. The main controller 20 may be a microprocessor such as a single chip, a DSP, or an FPGA, and the main controller 20 is configured to output a control signal to the alcohol detection device 30 when receiving an electrical signal indicating that a driver is present.
The alcohol detecting device 30 may be implemented by a circuit including an alcohol sensor, for example, a circuit including a GM302B alcohol sensor. The alcohol detecting device 30 is configured to operate and detect the alcohol concentration in the vehicle when receiving the control signal output by the main controller 20, and feed back the alcohol concentration information in the vehicle to the main controller 20.
The main controller 20 is further configured to determine a warning information level according to the received alcohol concentration information, and control the voice prompt module 60 to send a voice prompt corresponding to the warning information level; meanwhile, main controller 20 is also used for transmitting the early warning information grade and the current position information of the vehicle to preset terminal equipment 50 through bluetooth module 40, for example, transmitting to the APP corresponding to the mobile phone of the driver, and pushing the early warning information grade and the current position information of the vehicle to the APPs corresponding to other terminal equipment through the mobile phone APP of the driver.

When the main controller 20 receives the electric signal indicating that the driver is present, the main controller 20 controls the alcohol detection device 30 to detect the current alcohol concentration in the vehicle, and the alcohol detection device 30 may be disposed in front of the driver seat or in another suitable position close to the driver. The alcohol detection device 30 transmits the detected alcohol concentration information to the main controller 20, wherein, in order to reduce the power consumption of the system, the time length for detecting the alcohol concentration in the vehicle by the alcohol detection device 30 can be set by a timer inside the main controller 20, and when the timing time is reached, the main controller 20 controls the alcohol detection device 30 to enter a low power consumption mode.
