The automobile tail gas detection system comprises a detection unit and an upper computer, wherein the detection unit is mounted on an automobile chassis; the detection unit comprises a tail gas sensor, a signal conditioning circuit, a single chip microcomputer and an RFID reader-writer; the tail gas sensor is mounted on an automobile tail gas pipe; the tail gas sensor is connected with the single chip microcomputer by the signal conditioning circuit; the single chip microcomputer is in wireless communication with the upper computer by the RFID reader-writer and can be used for detecting tail gas components when an automobile runs on an actual rod and immediately judging whether automobile tail gas exceeds the standard or not according to a detection result; the detection time is reduced effectively and the application prospect is good.
Description
Technical field
The present invention relates to a kind of automobile emission gas analyzer system based on RFID, belong to electronic measuring technology field.
Background technology
Traditional method for detecting automobile exhaust gas adopts chassis dynamometer method of testing, and the principle of work of the method is: indoor, and binding chassis dynamometer machine and gas analyzer, the exhaust emissions amount of test machine motor-car under default motor-driven vehicle going operating mode.But because this method must be indoor, and require by fixing driving cycle, motor vehicle to be tested, therefore can not truly reflect the exhaust emissions on real road, and system for testing discharge volume is too huge, operating difficulties when use, detected vehicle often needs to spend a large amount of time and just can obtain testing result.
Summary of the invention
The object of the invention is to adopt chassis dynamometer method of testing in order to overcome traditional method for detecting automobile exhaust gas, must complete indoor, can not truly reflect the exhaust emissions on real road, test inconvenient problem.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
