Further, laboratory internal multiple ventilation modules according to itself numbering it is intermittent be operated, in this way, not
Ventilation can be only aerated to laboratory internal from multiple directions, and makes multiple ventilation modules that work is conducted batch-wise, made
Obtaining each ventilation module can be rested and be worked, it is to avoid same ventilation module continuous firing has situation about having damaged,
It is service life so as to extend laboratory internal each ventilation module, reduces the replacement cost of laboratory internal equipment.
Brief description of the drawings
Fig. 1 is a kind of structural representation of laboratory ventilation intelligent control system.
Specific embodiment
As shown in figure 1, Fig. 1 is a kind of laboratory ventilation intelligent control system proposed by the present invention.
Reference picture 1, laboratory ventilation intelligent control system proposed by the present invention, including：
Collecting unit, for gathering laboratory internal image information；Collecting unit includes multiple acquisition modules, and any one is adopted
Collection module includes a high-definition camera instrument, and the image information of laboratory internal can be comprehensively gathered using multiple high-definition camera instrument,
Increase the accuracy of laboratory internal image information collecting and comprehensive.
Analytic unit, for obtaining collecting unit collection laboratory internal image information, and laboratory internal image is believed
Breath carries out similarity comparison with pre-set image information, and exports similarity comparison result S；
Unit ventilators, is aerated for the instruction according to control unit to laboratory internal；
Control unit, communicates to connect with collecting unit, analytic unit, unit ventilators；
Control unit obtains similarity comparison result S by analytic unit, and S is compared with preset value, further according to
Comparative result instruction control unit ventilators action.
Specifically：Unit ventilators includes n ventilation module, n ventilation module be located on four side walls of laboratory internal and
Annularly it is arranged in order along four side walls of laboratory internal, is designated as W1、W2……Wn；
The first Similarity value S is preset with control unit1, the second Similarity value S2；
As S≤S1When, show that collection laboratory internal image information is relatively low with pre-set image information similarity, i.e. laboratory
There are a large amount of personnel inside, then have more personnel to carry out experimental implementation in laboratory, it is therefore desirable to increase the ventilation of laboratory internal
Strategy, now control unit instruction control unit ventilators action, by W1、W2……WnVentilation module is adjusted to working condition, by n
Individual ventilation module all starts work and carrys out stronger ventilation dynamics, within a short period of time adjust to suitable laboratory internal environment
Suitable scope；
Work as S1<S<S2When, show that collection laboratory internal image information has been raised with pre-set image information similarity, then
Laboratory internal has part Experiment personnel, then control unit instruction control unit ventilators action, by W2、W4……W2mOr W1、
W3……W2m-1Ventilation module is adjusted to working condition, while being operated using n/2 ventilation module, it is to avoid using more logical
Wind module works and causes the waste of the energy simultaneously, and W2、W4……W2mAnd W1、W3……W2m-1Ventilation module can be switched over, and be prevented
Only any ventilation module continuous firing causes the flimsy situation of ventilation module to occur；
As S >=S2When, show that collection laboratory internal image information is higher with pre-set image information similarity, i.e. laboratory
The reduction of Internal Experiment personnel amount, now without being aerated to laboratory internal using excessive ventilation module, control unit
Instruction control unit ventilators action, by W3、W6……W3mOr W1、W4……W3m-2Or W2、W5……W3m-1Ventilation module is adjusted to
Working condition so that W3、W6……W3mAnd W1、W4……W3m-2And W2、W5……W3m-1Ventilation module can switch over work,
Avoid any one ventilation module continuous firing from causing the flimsy situation of ventilation module to occur, make any one ventilation module is extended
Maintenance cost and replacement frequency are reduced with the basis of the life-span；
Wherein, n=6m, m are positive integer.
Present embodiment also includes detection unit, alarm unit, display unit；
Detection unit is used for test experience chamber interior pernicious gas content G；Detection unit is communicated to connect with control unit, control
Unit processed obtains laboratory internal pernicious gas content G by detection unit；
Alarm unit, communicates to connect with control unit, and according to the instruction alert of control unit；
The first content value G is preset with control unit1；
As G >=G1When, control unit sends instruction to alarm unit, and alarm unit is to be sent according to the instruction of control unit
Warning message, alarm unit uses audible-visual annunciator, can comprehensively remind relevant staff to notice that laboratory internal is harmful to gas
Body content is higher, facilitates relevant staff to take counter-measure in time, prevents laboratory internal pernicious gas to related work
The health of personnel is impacted.
Display unit is communicated to connect with control unit, and the laboratory internal that display unit is used for display control unit transmission has
Evil gas content G, relevant staff can in time understand laboratory internal pernicious gas content G by display unit.
By gathering laboratory internal image information, and laboratory internal image information is compared with pre-set image information
Similarity comparison result is relatively drawn, further according to the number of similarity result assay laboratory internal staff, further according in laboratory
The number of portion personnel selects targetedly Ventilation Strategies；Specifically：When similarity is relatively low, show laboratory internal personnel compared with
Many, then more personnel can not only reduce laboratory internal air quality, and more personnel are when experimental implementation is carried out
A part of gas can be formed to flow into laboratory, it is therefore desirable to increase the ventilation dynamics to laboratory internal, now then open real
Test all of ventilation module of chamber interior to be aerated laboratory internal, increased by increasing the quantity of the ventilation module opened
The ventilation dynamics of laboratory internal；When laboratory internal personnel are on the high side, then using the ventilation module of moderate quatity to laboratory
Inside is aerated ventilation；When laboratory internal personnel are less, then continue to reduce the quantity of the ventilation module opened, it is to avoid energy
The waste in source.
Further, laboratory internal multiple ventilation module is arranged in order along four side walls of laboratory internal, and multiple
Ventilation module forms ring-type, and so in multiple ventilation module unlatching work, multiple ventilation modules are from four direction to experiment
Chamber interior is aerated, and laboratory internal gas is comprehensively flowed with Acceleration study chamber interior gas and laboratory extraneous gas
Exchange velocity, improve laboratory internal gas exchange rate, it is ensured that the ventilation effect of laboratory internal.
Further, laboratory internal multiple ventilation modules according to itself numbering it is intermittent be operated, in this way, not
Ventilation can be only aerated to laboratory internal from multiple directions, and makes multiple ventilation modules that work is conducted batch-wise, made
Obtaining each ventilation module can be rested and be worked, it is to avoid same ventilation module continuous firing has situation about having damaged,
It is service life so as to extend laboratory internal each ventilation module, reduces the replacement cost of laboratory internal equipment.
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.
