一类公交车厢内易燃气体智能检测系统的设计

Design of Intelligent Monitoring System for Inflammable Gas in Bus Compartment

在日常生活及工业生产中,易燃性液体的应用都十分广泛。但与此同时,易燃性液体也带来巨大风险,特别是在公交车厢内。由于国内目前对于易燃液体的检测存在灵敏度方面的缺陷,因此十分容易被不法分子利用造成纵火案危害社会。针对该缺陷,设计出一套智能系统。该智能系统分为两台检测仪器与一台终端显示屏,检测仪器分别位于前后门处,终端显示屏则位于公交车仪表盘周围。其设计目的是:通过位于车门处的检测仪器,对上车乘客所携带的、公交车厢内部的易燃液体所散发出的气体分子浓度进行高灵敏度的智能检测,并通过终端显示屏进行声光报警,从而确保乘客安全,维护社会稳定。

The use of flammable liquids is extensive in everyday life or industrial production.At the same time,however,flammable liquids also pose great risks,especially in bus compartments.Because of the current sensitivity defects in the detection of flammable liquids in the country,it is very easy to be exploited by lawless elements to cause arson damage society.In response to this defect,an intelligent system was designed.The intelligent system is divided into two detection instruments and one terminal display.The detection instruments are located at the front and rear doors,and the terminal display is located around the dashboard of the bus.The purpose of the design is to perform high-sensitivity intelligent detection of the concentration of gas molecules emitted by the flammable liquid inside the bus compartment carried by the passengers on the vehicle through the detection instrument located at the door of the vehicle,and perform sound and light through the terminal display screen.Alarms to ensure passenger safety and maintain social stability.
