First reaction module 4 and the second reaction module 5 are separately connected the processing module 6, and the processing module 6 connects described device
Module 7, described device module 7 are directly connected to second reaction module 5, and the scattering optical receiver module 2 is scattered for receiving
Light, the scattering optical receiver module 2 includes several receiving modules 21, if first reaction module 4 includes dry reaction module 41,
The receiving module 21 is corresponded with the module 41 that reacts, and 21 individual reception of the receiving module scatters light, is connect with described
Receive the metering that the corresponding reaction module 41 of module 21 is scattered light light intensity longitudinal direction degree of change and lateral degree of change, the signal
Light specifies receiving module 3 to receive via the final signal light propagated in air medium, and final signal light is anti-by described second
Module 5 is answered to act on described device module 7, the mode of action acts on for reverse current, and described device module 7 is according to described anti-
The change of ventilation dynamics is carried out to the function of current.
As a kind of preferred embodiment of the present invention, described device module 7 is provided with operating circuit and workpiece, the work
Make to be connected with forward voltage in circuit, forward voltage be used for workpiece convey forward current, the forward current with it is described
Reverse current synthesizes effective current, and the effective current driving workpiece carries out the ventilation work of room air.
As a kind of preferred embodiment of the present invention, the macroscopic view of the scattering light light intensity longitudinal direction degree of change and lateral degree of change

Degree of change carries out the amendment of forward current size in the operating circuit.
As a kind of preferred embodiment of the present invention, the Microscopic of the forward current size correction result is effective current
The change of size, the macro manifestations of the correction result of the forward current size are the change of air exchange system ventilation dynamics.
In specific implementation process, scattering optical receiver module 2 device setting on the ceiling, signal optical module 1 and
Signal light specifies receiving module 3 to be separately positioned on the wall of opposite face.Signal optical module 1 sends out signal light, signal to interior
The wavelength of light is much larger than the curvature of dust particles lamp impurity in room air, therefore, meeting when signal light is propagated in air medium
There is a situation where scattering, signal light is scattering, and the light intensity on the direction of propagation of script reduces, and letter is propagated in signal light
When number light specifies receiving module 3, it is photoelectricity to specify the reaction unit for the second reaction module 5 that receiving module 3 is connected with signal light
Pipe, photoelectric tube carry out the generation of photogenerated current using photovoltaic effect, and forward direction is electric in the direction of photogenerated current and operating circuit
The forward current direction generated is pressed on the contrary, the electric current that therefore the second reaction module 5 is generated according to signal light reaction is as reversed electricity
Stream acts on operating circuit, and light intensity is bigger, and reverse current is bigger, and the effective current in operating circuit is smaller, causes big straight of light intensity
It is that scattering degree is small to connect reason, and the basic reason for causing scattering degree small is the more uniform and not more particle of air dielectric
Shape dust, i.e. air quality are good, need not carry out the ventilation of very great dynamics at this time, therefore, correspondingly, effective current is smaller, and work
The power for making component acquisition is smaller, and ventilation dynamics is small；The smaller reverse current of light intensity is smaller, and the effective current in operating circuit is got over
Greatly, the immediate cause for causing light intensity small is that scattering degree is big, and the basic reason for causing scattering degree big is that air dielectric is uneven
And having more graininess dust, i.e. air quality is bad, the ventilation for carrying out very great dynamics is needed at this time, therefore, correspondingly, having
Effect electric current is larger, and the power that workpiece obtains is larger, great efforts of taking a breath.
Scattering light is propagated after scattering around, scattering optical receiver module 2 receives scattering light, scatters optical receiver module 2
Receiving module 21 receive scattering light respectively, reaction module 41 corresponding with receiving module 21 is scattered the meter of light light intensity
Amount, for longitudinal degree of change, each reaction module 41 is recorded in the light for the scattering light that receiving module 21 in Each point in time receives
By force, it and is compared, postorder time point scattering light light intensity is subtracted into preamble time point scattering light light intensity, calculate scattering light each
The real-time degree of change of 21 inside light intensity of receiving module, and real-time degree of change is compared according to chronological order, work as reaction
When module 41 judges the numerical value of real-time degree of change to increase just and constantly, reaction module judges that scattering light light intensity becomes larger, and then sentences
Disconnected air quality is poor, needs to increase ventilation dynamics, processing module 6 is adjusted the operating circuit of apparatus module 7 so that positive
Electric current becomes larger；When reaction module 41 judges the numerical value of real-time degree of change for negative and constantly reduction, reaction module judges to scatter light
Intensity becomes smaller, and then judges that air quality gradually improves, and needs slowly to reduce ventilation dynamics at this time, processing module 6 is to device mould
The operating circuit of block 7 is adjusted so that forward current becomes smaller.For lateral degree of change, each reaction module carry out mutually it
Between realtime scatter light light intensity mathematic interpolation, difference is lateral degree of change, and when lateral degree of change is big, each reaction module is all sentenced
Disconnected scattering degree is bigger, and processing module 6 is adjusted the operating circuit of apparatus module 7 so that forward current becomes larger；Work as cross
To degree of change hour, each reaction module all judges that scattering degree is smaller, operating circuit of the processing module 6 to apparatus module 7
It is adjusted so that forward current becomes smaller.
