Smart detection system for safety driving

Abstract

The invention relates to a smart detection system for safety driving. The smart detection system comprises a single chip microprocessor controller, and also comprises an oxygen sensor, a CO sensor, anethanol sensor, a temperature sensor, an AD sampling module, a display module, an alarming module and a power supply module; the oxygen sensor, the CO sensor, the ethanol sensor and the temperature sensor are respectively used for detecting oxygen concentration, carbon monoxide content, ethanol concentration and temperature in a car, the sensors are connected with the input end of the single chipmicroprocessor controller by virtue of the AD sampling module, and the output end of the single chip microprocessor controller is connected with the display module and the alarming module; the powersupply module is connected with the single chip microprocessor controller; and the ethanol sensor is of a heater-type structure and comprises a sensitive material, and the sensitive material is a composite metal oxide and specifically a mixture of ZnSnO3 nanospheres and SnO2 nano particles.

Description

technical field [0001] The invention relates to the technical field of gas detection for safe driving, in particular to an intelligent detection system for safe driving. Background technique [0002] With the rapid development of social economy, more and more families own cars, but the harmful gas components in cars are often not paid attention to. Especially in hot summer and cold winter, people often like to turn on the air conditioner in the car when driving, but when the car window is closed for a long time, the oxygen concentration in the car will drop and the carbon dioxide concentration will rise, which will easily cause the driver to feel dizzy. In addition, due to the insufficient combustion of gasoline, a large amount of exhaust gas containing carbon monoxide is produced. If these exhaust gases cannot be discharged in time, carbon monoxide will accumulate in the car, which is very likely to cause carbon monoxide poisoning to the driver. All of these have laid a saf...

Especially in the hot summer and cold winter, people often like to turn on the air conditioner in the car when driving, but when the windows are closed for a long time, the oxygen concentration in the car will drop and the carbon dioxide concentration will rise, which will easily cause the driver to feel dizzy

In addition, due to the insufficient combustion of gasoline, a large amount of exhaust gas containing carbon monoxide will be produced. If these exhaust gases cannot be discharged in time, carbon monoxide will accumulate in the car, which is very likely to cause carbon monoxide poisoning for drivers. All of these have laid a safety hazard for driving.
