Description
Technical field
The present invention relates to a kind of vehicle exhaust and remotely monitor rare earth sensor array detecting system, belong to electronic information technology
Field.
Background technology
Current automobile exhaust pollution constantly increases the weight of more and more higher with automobile emission gas analyzer standard, in vehicle exhaust containing CO,
Organic polymer flue gas, NOx, sulfiding gas etc., these tail gas are harmful and affect natural environment, and this has evolved into
Serious social problem.
How to monitor the discharge of vehicle exhaust, and efficiently reduce the toxic and harmful dirt to atmospheric environment in tail gas
Dye, is global environmental protection subject.And the premise administered is effectively to monitor the discharge of vehicle exhaust.
At present, the detection of vehicle exhaust is paid much attention to by China, is provided with automotive emission standard and motor-driven vehicle
Gas environmental mark.There is special Tail gas measuring station to Vehicle Inspection of submitting to a higher level for approval or revision, as the required Inspection Index item that whether qualified annual examination is.But remove
In special Tail gas measuring station detection, on road, in the most of the time that automobile uses, place, monitor the most never again
Means, understand the motor vehicle exhaust emission situation on road, the most just do not know that location automobile exhaust pollution is serious, also may be used simultaneously
Can be to block up seriously.It is to say, we are to vehicle exhaust at present, only the detection means when appointed place annual test, does not has
Online, real-time monitoring means.
In the main roads that traffic circulation amount is bigger, major metropolitan areas, tail gas online, monitoring automobile in real time, one is can
To understand present road or the exhaust emissions amount in region, find the abnormal conditions of the waste gas discharge in this road or area in time, also
Can be added up by the total emission volumn of certain time, reflect traffic conditions and the atmospheric pollution situation of this area.Simultaneously as
The unexpected discharge beyond standards of tail gas and automobile block up and there is certain association, by the exhaust emissions state of monitoring this area road,
It is recognized that the traffic pressure of this area's road and congestion status.This just explanation, monitors main roads, mainly online, in real time
The exhaust emissions amount in city is a good project achieved many things at one stroke.
The method being currently used for analysing tail gas of vehicle mainly has three kinds, it may be assumed that use not light splitting infrared analysis (NDIR) measurement CO,
HC and NO；HC is measured with hydrogen flame ion analyser (FDI)；NOx and O2 is measured with electrochemical principle.But, current tail
Gas comprehensive detection device is since it is desired that the exhaust gas constituents of detection is the most, in addition it is also necessary to pretreatment unit and sampler, needs multiple
Miscellaneous manual operation, compares bulky, and energy consuming ratio is higher, involves great expense, it is impossible to the on-line monitoring being used on highway, affects him
Promoting the use of of highway network and major metropolitan areas, automatic monitoring also cannot be accomplished.Cause the tail gas of road network and major metropolitan areas
Environmental monitoring is a blank field in the whole nation.
China's atmospheric haze, it is main cause that industrial exhaust gas pollutes, but pollutes for industrial gases, has had very
Many ripe monitoring devices and monitoring means are currently in use.Motor-vehicle tail-gas is considered also to be an important polluter, current tail
Gas monitoring great majority are to be monitored by main equipment in automobile monitoring center, are discrete and heavy costlinesses.Up to now, do not have
There is one to be suitable for extensive installation, promote, the tail gas sensor that automatization monitors in real time.Frequent outburst along with PM2.5 event
With the arrival on the date of China petrol and diesel oil standard upgrade, motor-vehicle tail-gas is monitored in the urgent need to taking the most advanced technology.
Also having a real problem, even if there being such tail gas sensor, being arranged on highway network, the survey of sensor
Amount data need to be transferred to monitor control centre, in Xinjiang region, it may be possible to thousands of miles away, for transmission data wiring cost too
Height, is impossible.So the tail gas sensor measurement data of highway monitoring must wirelessly remote transmission
To Surveillance center.Meanwhile, working sensor electricity consumption to control in low energy consumption standard, and must accomplish can be self-supporting in the wild
Self-sustaining.So, to install simple, exempt from wiring for one, cost is low, and volume is little, and energy consumption is low, self-powered, it is possible to realize remote data transmission
Multi-functional tail gas sensor and monitoring system thereof are the new products required for market.
Summary of the invention
It is an object of the invention to provide a kind of vehicle tail gas and remotely monitor rare earth sensor array, solve existing skill
