有害气体泄漏实时报警广播系统的研究

Research on Real-time Alarm Broadcasting System for Harmful Gas Leakage

许多工业生产过程,如石油、化工、冶炼、煤炭、电焊、电镀等行业,都会产生各种有毒有害气体,这些气体多易燃易爆且具有刺激性、腐蚀性,形成不利于人类活动的环境污染,危害人们的身体健康。特别是像一氧化碳、氢气、硫化氢、汽油以及苯类、醇类、烷类等有毒有害气体,在某场所如发生泄漏,可燃气体浓度超标,所产生的与空气的混合物遇到火源或者热源,就会引起火灾爆炸事故。有毒有害气体的存在,不可避免,但是可以预防,只要我们能及时发现有毒气体的存在和浓度,报警信息的及早广播发布极为重要,获取泄漏点的位置和电信运营商基站信息,通过手机短信和APP(带电子地图及应对预案),告知附近的人们不要产生明火,同时通知人们和车辆(特别是公交和其它车辆)远离该地区,就显得尤为重要!这对于提高灾害监测技术与管理水平具有一定的理论和实践参考价值。

Many industrial production processes,such as petroleum,chemical,smelting,coal,electric welding,electroplating and other industries,will produce various toxic and harmful gases.These gases are flammable,explosive,irritating and corrosive,forming an environment that is not conducive to human activities.Pollution harms people's health.In particular,toxic and harmful gases such as carbon monoxide,hydrogen,hydrogen sulfide,gasoline,benzene,alcohols,alkanes,etc.,if there is a leakage in a certain place,the concentration of combustible gas exceeds the standard,and the mixture generated with air encounters a fire or heat source.,will cause fire and explosion accidents.The existence of toxic and harmful gases is unavoidable,but it can be prevented.As long as we can detect the existence and concentration of toxic gases in time,it is extremely important to broadcast and release alarm information as soon as possible.Obtain the location of the leak point and the information of the base station of the telecom operator.APP(with electronic map and response plan),it is particularly important to inform people nearby not to generate open flames,and to inform people and vehicles(especially buses and other vehicles)to stay away from the area!This has certain theoretical and practical reference value for improving disaster monitoring technology and management level.
