The existing solution is, for example, patent application No. 201711399945.5, an alcohol testing device, which is mounted on a steering wheel, and can detect whether a driver is a drunk driver in real time and give an alarm to remind the driver, but if the driver wears a mask or other passengers in a car drink alcohol and exhale alcohol with a high concentration, the alcohol testing device will affect the testing result of the tester, and the alcohol testing device only stays at the warning level, and no measure for further protecting the passengers is provided. Patent application No. 201811167612.4 discloses that the alcohol concentration in the cab of a vehicle can be obtained by emitting laser light into the cab and calculating the intensity of the reflected laser light to be different, but if there is a person who drinks but does not drive the passenger in the cab, the test result is also influenced. The alcohol test system can eliminate drunk driving from the source, can remove measures such as fire break of a safety belt engine of a driver and forbid cheating tests of the driver through fixed position alcohol tests, ensures that the driver is the person who passes the alcohol test, thoroughly eliminates drunk driving from the source, can greatly reduce traffic accidents, and protects the life safety of drivers and passengers.
