The ventilation effect of ventilation module and third venting module, and in t2The first ventilation module and third venting module are adjusted after time
Opening is adjusted to for closed mode, by the second ventilation module and the 4th ventilation module and be the second ventilation module and four-way
Wind module selects the first air draft grade, and further analyzes t4C after timei+1", if Ci+1”≥dCi+1', show the second ventilation
Module and the 4th ventilation module are in work t4Time rear venting DeGrain, is now raising the second ventilation module and four-way
The ventilation effect of wind module, by the second ventilation module and the 4th ventilation module be adjusted to opening and for the second ventilation module and
4th ventilation module selects the second air draft grade, is added by increasing the air draft grade of the second ventilation module and the 4th ventilation module
The air draft dynamics of big second ventilation module and the 4th ventilation module, within a short period of time adjust laboratory hood internal gas concentration
It is whole to OK range；
Work as Ci+1≥cCiWhen, showing that now the laboratory hood internal gas concentration rate of climb is very fast, then being piled up in laboratory hood has
A large amount of gases, to avoid laboratory hood interior gas amount from persistently raising, control unit instruction control unit ventilators action is led to first
Wind module, the second ventilation module, third venting module, the 4th ventilation module are adjusted to opening and are the first ventilation mould
Block, the second ventilation module, third venting module, the 4th ventilation module select the first air draft grade, and further analyze t5Time
C afterwardsi+1" ', if Ci+1”'≥dCi+1, show the first ventilation module, the second ventilation module, third venting module, the 4th ventilation mould
Block work t5After time, gas concentration is still higher in vent cabinet, now by the first ventilation module, the second ventilation module, the 3rd
Ventilation module, the 4th ventilation module are adjusted to opening and are the first ventilation module, the second ventilation module, third venting mould
Block, the 4th ventilation module select the second air draft grade, by for the first ventilation module, the second ventilation module, third venting module,
4th ventilation module selects larger air draft grade to increase the dynamics being aerated to vent cabinet inside, further speeds up ventilation
The velocity of discharge of cabinet internal gas；
When first row wind grade is selected, the first ventilation module and/or the second ventilation module and/or third venting module
And/or the 4th the operating power of ventilation module remain P1, when second row wind grade is selected, the first ventilation module and/or the
The operating power of two ventilation modules and/or third venting module and/or the 4th ventilation module remains P2；
Wherein, P1<P2。
Present embodiment, also including alarm unit, display unit；
Alarm unit is communicated to connect and according to the instruction alert of control unit with control unit；
Maximum concentration value C is preset with control unitmax；
Work as Cj≥CmaxWhen, control unit sends instruction to alarm unit, and alarm unit is to be sent out according to the instruction of control unit
Go out warning message, to remind relevant staff to notice vent cabinet internal gas concentration situation higher, facilitate related work
Personnel take counter-measure in time, prevent relevant staff from being impacted to health in the case of unwitting；
Wherein, 1≤j≤n.
The information that display unit is communicated to connect with control unit and sent for display control unit；
Control unit obtains vent cabinet internal gas concentration C by collecting unit1、C2……Cn, and by C1、C2……CnHair
Display unit is delivered to, facilitates relevant staff to watch vent cabinet inside real gas concentration value in time.
Judge whether need to be aerated inside vent cabinet by the gas concentration in Real-time Collection vent cabinet, and when logical
Ventilation Strategies are selected according to the gas concentration value in vent cabinet when needing to be aerated inside wind cabinet, to realize to vent cabinet inside
The specific aim being aerated.Specifically：Respectively in the time point collection vent cabinet internal gas concentration of same intervals, then will be nearest
Detected value once is compared with the detected value of last time, and comparative result according to detected value twice is judged in Preset Time
The situation of change of interior vent cabinet internal gas concentration, and Ventilation Strategies are selected according to the situation of change of gas concentration, in this way, can
Actual change situation according to vent cabinet internal gas selects targetedly Ventilation Strategies, it is ensured that money is avoided while ventilation effect
The waste in source.When gas concentration is reduced to certain value, show in now vent cabinet without continuing to produce pernicious gas, that is, test
Operation has stopped or has suspended, and now considers for energy-conservation, then do not use ventilation operation to vent cabinet；When gas concentration rising value compared with
When low, show that the value of gas concentration in Preset Time is smaller, now using the ventilation dynamics of low-force degree, i.e., using relative
Two ventilation modules for setting are aerated to vent cabinet inside, realize circulating for vent cabinet internal gas, accelerate ventilation
The velocity of discharge of cabinet internal gas, and enter in switching another two ventilation module after above-mentioned two ventilation module works Preset Time
Row work, makes vent cabinet internal gas realize circulating on another direction, not only can comprehensively make vent cabinet internal gas
Flowed, and four ventilation module alternations can avoid single ventilation module continuous firing from easily causing the situation of infringement
Occur, extend four life-spans of ventilation module to save replacement cost；When gas concentration ascensional range is larger, show default
Vent cabinet internal gas concentration rises very fast in time, i.e., substantial amounts of gas is generated in Preset Time, now to avoid producing
Raw gas is deposited in inside vent cabinet, it should stronger ventilation dynamics, then start four ventilation modules simultaneously to vent cabinet inside
It is aerated, the circulation of vent cabinet internal gas is driven by making the comprehensive flowing in the horizontal direction of vent cabinet internal gas
Speed, accelerates the exchange velocity of vent cabinet internal gas and vent cabinet extraneous gas, to reduce inside vent cabinet in a short time
Gas concentration, environment in vent cabinet is adjusted to health status.
Further, when Ventilation Strategies are taken, to detect the ventilation effect of current Ventilation Strategies, then after Preset Time
Collection again and is analyzed vent cabinet internal gas concentration to it, as vent cabinet internal gas concentration reducing effect not Jia Shijia
The air draft grade of big ventilation module fully ensures that drafting efficiency to improve the ventilation effect to vent cabinet.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technology according to the present invention scheme and its
Inventive concept is subject to equivalent or change, should all be included within the scope of the present invention.
