Abstract

The invention discloses a control and detection device for preventing drunk driving, which is used to detect alcohol in the driver and the car, including storage battery, fuse, ignition switch, multiple infrared alcohol detection sensors, normally closed relay, engine starter and car engine control module, the storage battery, fuse, ignition switch, normally closed relay, engine starter and vehicle engine control module are sequentially connected in series, and the plurality of infrared alcohol detection sensors are respectively arranged in parallel with the fuse and the storage battery. The invention can automatically cut off the engine starter power supply after the infrared alcohol detection sensor detects that the driver's alcohol exceeds the standard, so that the car cannot be started and the driver cannot drive after drinking.

Example Embodiment

[0014] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to make a clearer and clearer definition of the protection scope of the present invention.
[0015] The present invention is a control detection device for preventing drunk driving, such as figure 1 As shown, it is used to detect alcohol in the driver and the car, including battery 1, fuse 2, ignition switch 3, multiple infrared alcohol detection sensors 4, normally closed relay 5, engine starter 6, and car engine control module 7. The battery 1, the fuse 2, the ignition switch 3, the normally closed relay 5, the engine starter 6, and the automobile engine control module 7 are sequentially connected in series, and the plurality of infrared alcohol detection sensors 4 are respectively arranged in parallel with the fuse 2 and the battery 1.
[0016] The ignition switch 3 is a one-key start switch of the car.
[0017] The rated voltage of the battery 1 is 12V or 24V.
[0018] The automobile engine control module 7 is a single-chip microcomputer.
[0019] The plurality of infrared alcohol detection sensors 4 include a first infrared alcohol detection sensor 41, a second infrared alcohol detection sensor 42, a third infrared alcohol detection sensor 43, and a fourth infrared alcohol detection sensor 44. The first infrared alcohol detection sensor 41. The second infrared alcohol detection sensor 42, the third infrared alcohol detection sensor 43, and the fourth infrared alcohol detection sensor 44 are respectively arranged at the door, the center of the steering wheel, the left side of the steering wheel, and the ignition switch of the automobile.
[0020] When the driver is not drinking or drunk, the normally closed relay 5 is closed and the car can start and work normally; when the driver is drinking or drunk and the driver opens the car door, the first infrared alcohol detection sensor 41 of the car door will detect driving Whether the alcohol content of the employee’s watch skin exceeds the limit; when the driver enters the car’s cab and tries to start the car, the second infrared alcohol detection sensor 42 and the third infrared alcohol detection sensor 43 are located at the center of the steering wheel, the left side of the steering wheel and the ignition switch position And the fourth infrared alcohol detection sensor 44 will detect the alcohol level of the driver at the same time. If the alcohol level detected by any infrared alcohol detection sensor 4 exceeds the standard, the automobile engine control module 7 energizes the coil of the normally closed relay 5, and the normally closed switch contacts Disconnected, the car engine starter 6 is powered off, and the car cannot start.
[0021] The present invention is a control and detection device for preventing drunk driving. The present invention can automatically cut off the power of the engine starter after the infrared alcohol detection sensor detects that the driver's alcohol exceeds the standard, so that the car cannot be started, and the driver cannot drive after drinking.
[0022] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can make changes or substitutions without creative work within the technical scope disclosed in the present invention. , Should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
