Entirely.
The technical scheme that the present invention uses is：One tail gas collection dress with electromagnetic switch is installed on automobile exhaust pipe
Put, tail gas is guided in detection means by flexible pipe.Detection means is built with sensor cluster, air pump assembly and circuit system.
Sensor cluster is a box for having 2 air inlet/outlets, built with several sensors for detecting tail gas difference index respectively.Gas
Pump group part is by a two-way air pump and can be formed with the motor of forward and reverse rotation.Circuit system is by power circuit block, the Big Dipper
Locating module, wireless transport module, sound detection module, acceleration detection module, computer and sensor amplifier circuit composition.
Air-channel system is by air pump assembly, magnetic valve, the composition such as one-way cock and air cleaner.The effect of tail gas harvester is to collect
Vehicle exhaust.Valve is opened during detection sensor cluster is sent to by air pump suction tail gas.Valve is closed when not detecting, prevents tail
Gas enters, and prevents dirt accumulation and blocks gas circuit.The effect of sensor cluster is detection exhaust gas component, and the data of sensor are amplified
After be sent to computer.Another effect of air pump assembly is that the extraneous air by air cleaner is sent to sensor, cleaning
Calibration reference can also be provided while sensor for sensor.The effect of the magnetic valve and check valve of gas circuit is：During detection, protect
Card tail gas is sent to sensor cluster, when cleaning or calibration sensor, makes to be sent to sensor group by the gas of air cleaner
Part.The effect of circuit system is：Using computer emission data, sound detection module, the acceleration gathered by sensor
The data of detection module collection and the data of Big Dipper locating module are passed through by being sent to from wireless transport module on wireless network
Network is sent to environmental monitoring mechanism, and environment monitoring mechanism can be by these data to bus location and to the tail gas shape of automobile
State is monitored in real time.
The beneficial effects of the invention are as follows：Real-time monitoring can be carried out to motor vehicle exhaust emission, one kind is provided for environmental protection
Convenient means.

Embodiment
The present invention is further described with reference to the accompanying drawings and examples.
Tail gas harvester sketch is shown in Fig. 1.Electromagnet 1 and the valve 2 of side band opening are arranged on shell 7
In.Valve seat 4 is the pipe of a lateral opening, is riveted in fixed seat 5.Valve 2 is through among valve seat 4, forms a rotation
Turn on the valve closed.There are 2 magnet on valve 2, when a magnet contacts with the iron core of electromagnet 1, the opening and valve of valve 2
The opening of gate seat 4 is overlapped, and valve is opened；When another magnet contacts with the iron core of electromagnet 1, the opening and valve of valve 2
The opening of seat 4 staggers, and valve is closed.Pass through the supply current direction to electromagnet 1, thus it is possible to vary the magnetic pole of the iron core of electromagnet 1
Direction.The iron core of electromagnet 1 pushes away to 2 magnet one on valve 2, a drawing, makes a magnet attraction in the iron of electromagnet 1
On core, after electromagnet 1 powers off, magnet is still pull-in on the iron core of electromagnet 1, keeps the state of valve.When electromagnet 1
When the sense of current is opposite, then valve turns to another state.The effect of clip 6 is that shell 7 is fixed in fixed seat 5, fixed
The effect of collar 3 is that collector is fixed on blast pipe.
The valve mechanism schematic diagram described in Fig. 1 is shown in Fig. 2.In fig. 2, the top-side of valve element 21 has an opening,
Middle part is provided with 2 magnet 22.The pole orientation of 2 magnet 22 is identical, and at an angle, ensures a magnet 22 and electromagnetism
Valve is opened during the iron core adhesive of iron 1, and valve is closed during the iron core adhesive of another magnet 22 and electromagnet 1.
Gas circuit schematic diagram is shown in Fig. 3.In figure 3, magnetic valve 31 illustrates that the valve of above-mentioned Fig. 1 descriptions.Electromagnetism
One end of the passage of valve 31 is connected to blast pipe, an another gas port for terminating to sensor box 32, another gas of sensor box 32
Mouth is connected to the gas port of two-way air pump 33, and another gas port of two-way air pump 33 is connected to exhaust check valve 34 and cleaner is unidirectional
Valve 35, cleaner check valve 35 are connected to air cleaner 36.Magnetic valve 31 is closed when flat.During measurement, magnetic valve
