During generate water, guide discharge.
The cabinet 9 of this example can conveniently be installed to automobile trunk, prevent from being rocked during the examination of road, fall；Tails assay device 2
Can Fast Installation, dismounting, and can well be fixed on cabinet 9.If automobile trunk does not have space, it is also possible to which cabinet 9 is put
Put on back seat.
As shown in figure 3, the inspection software of the portable car-mounted discharge detecting system of this example is arranged in detection platform, institute
Detection method is stated to comprise the following steps：
S1：Start, information of vehicles typing, system has three kinds of vehicle registration modes：（1）Information of vehicles is realized by from mobile phone
Typing；（2）Information of vehicles typing can be realized by flat panel industry computer；（3）Can realize that information of vehicles is recorded by PC computers
Enter.
S2：Judge whether calibration, if it is, probe is taken out in prompting, send and perform order time delay 1 second, then perform step
S3, if not, directly performing step S3；
S3：Transmission performs order；
S4：Whether data are received, gathered data is clicked on, effectively the data of collection is judged, if effectively, data are preserved, if nothing
Effect, return re-executes step S4；
S4：Judge whether to preserve data, if it is, uploading data, terminate, if not, extending 1 second, return and perform step S3.
The exhaust sampling device 1 of this example is per second at least to gather five gas（CO、HC、NOx、CO2、O2）, and λ data, wherein
λ represents excess air coefficient.
The definition of excess air coefficient is：Oxygen quality actually required for burning 1kg gasoline is more complete in theory than upper
Oxygen quality required for burning 1kg gasoline.Formula is：λ=amount of actual air for combustion/theoretical air requirement.
Work as λ>When 1, represent that combustion mixture is dilute, also have oxygen remaining after burning；Work as λ<When 1, flammable mixing is represented
Gas is dense, does not have oxygen remaining after burning；When λ=1, gasoline is completely burned, and oxygen is just depleted completely.This
The example synchronous acquisition GPS location data of detection platform 6, calculate correspondence vehicle speed data, and the five destinys evidence for gathering is carried out automatically
Judge, exclude sampling probe and come off the improper data for causing.
Vehicle completes the examination of road collection, and tails assay device 2 transfers data to detection platform 6 by blueteeth network, if
Data transmission fails and check errors, the system possess data retransmission function.
The system detection platform 6 carries out archives to the vehicle data that tails assay device 2 sends according to car plate and VIN yards
Management, vehicle the examination of road gathered data is stored under improvement vehicle map file.Preserving data can inquire about, transmits, delete.Delete
Data need password authorization.
The system such as can be demarcated, be examined and determine at the attended operation to five gas modules, and the use of tails assay device needs to use
Family is logged in and cryptographic check, and password authorization is needed to operations such as system maintenance, data deletions.
Discharged with system detectio vehicle of the invention, be placed on vehicle in use, travel 2 kilometers of roads, can in real time measure motor-driven
The parameters such as each form feature of concentration and quality, motor vehicle of each composition of tail gas.
The present invention can save substantial amounts of testing time and test specimens while the accuracy and reliability of test is ensured
This, can solve the limitation of existing test scope and the problems such as with testing cost higher.Portable vehicle-mounted discharge is surveyed
