Embodiment Construction

[0021] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0022] refer to figure 1 As shown, the present invention provides a vehicle-mounted alcohol concentration measuring device based on multi-sensor anti-interference, including an alcohol detection module, a vehicle-mounted main control module, an LCD liquid crystal display module, an LED indicator module, a voice alarm module and an engine control module. The alcohol detection module adopts an electronic nose system, which includes a gas sensor array, a signal preprocessing unit and a fuzzy pattern recognition unit. The gas sensor array is equivalent to the primary olfactory neuron, which consists of 6 metal oxide semiconductor gas sensors, a humid...

Abstract

The invention relates to the technical field of alcohol concentration measurement and discloses vehicle-mounted measurement equipment for alcohol concentration based on multisensor interference resistance. The vehicle-mounted measurement equipment comprises an alcohol detection module, a vehicle-mounted main control module and the like and is characterized in that the alcohol detection module adopts an electronic nose system and comprises a gas sensitive sensor array, a signal preprocessing unit and a fuzzy pattern recognition unit, wherein the gas sensitive sensor array consists of six metal oxide semiconductor gas sensitive sensors, a humidity sensor, a temperature sensor, an oxygen sensor and a smog sensor; and the devices are manufactured in one unit module. When a detected alcohol concentration value exceeds the standard, if the engine is in a stop state, the engine is forbidden to start; if the engine is in operating state, a driver is warned to park; and if the driver does not listen to discourage, an accelerator is gradually reduced for decelerating, and finally the engine is forcibly closed within a set time.

Description

technical field [0001] The invention relates to the technical field of alcohol concentration measurement, and more specifically relates to a vehicle-mounted alcohol concentration measurement device based on multi-sensor anti-interference. Background technique [0002] In recent years, nearly one-third of the major traffic accidents in our country were caused by drunk driving. Therefore, the detection of the driver's drinking level is getting more and more attention, and the alcohol concentration monitor has been widely used gradually. The alcohol concentration monitor can not only be used as a evidence collection tool for the traffic police to quickly and accurately judge whether the driver is drunk and driving, but also can be used for the driver to self-test whether he has drunk too much. [0003] At present, the domestic detection of drunk driving is mainly some conventional methods, that is, blood alcohol testing with a hand-held breath alcohol tester and a headspace ga...
