Accompanying drawing explanation
Fig. 1 is the perspective view of a kind of experimental ventilation hood of the present invention.
Fig. 2 is the organigram of a kind of experimental ventilation hood of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
Such as Fig. 1, shown in Fig. 2, a kind of experimental ventilation hood of the present invention, it comprises cabinet 11, with the air draft pipeline 15 that cabinet 11 top is docked, it is positioned at the blower fan 14 of air draft pipeline 15 docking location, it is positioned at the cut-and-try work district 17 of cabinet 11, it is positioned at the perspective window 13 of the glass on front side of cut-and-try work district 17, it is positioned at the illuminating lamp tube 12 at top, cut-and-try work district 17, drive the drive-motor 21 of glass perspective window 13 lifting, the motor driving circuit 23 of control drive-motor 21 working order, with the lamp tube drive circuit 22 that illuminating lamp tube 12 is electrically connected, with the fan drive circuit 24 that blower fan 14 is electrically connected, respectively with the controller 25 of motor driving circuit 23 and lamp tube drive circuit 22 and fan drive circuit 24 electric connection, wear and earphone-microphone 18 for gathering and play speech signal for experimenter, the wireless signal transmission module 28 of Signal transmissions is carried out with earphone-microphone 18, the speech recognition module 27 being electrically connected with wireless signal transmission module 28 and controller 25 respectively, with the display module 26 that described controller 25 is electrically connected, with the Keysheet module 29 that described controller 25 is electrically connected.Wireless signal transmission module 28 is integrated with the dual communication device sending and receiving, and for receiving the speech signal of earphone-microphone 18, and is transferred to speech recognition module 27, simultaneously also for pushing Fume Hoods status information to earphone-microphone 18. Speech recognition module 27 comprises audio collection module and voice signal processing module, the speech signal that audio collection module transmits for receiving wireless signal transmission module, voice signal processing module identification judges that the electric signal transmission forming various control command is to control module. By speech recognition module 27 and wireless signal transmission module 28, user is made can conveniently to be adjusted the operating parameter of Fume Hoods by Voice command when testing, when testing, user can be absorbed in experimental subjects itself, and muscle power need not be expended and remove the various devices manipulating Fume Hoods, experimental chemistry material is avoided to be infected with Keysheet module by gloves and cause crossed contamination, the health of infringement experimenter.
Adopt the lifting state of Voice command glass perspective window 13, save the human cost of elevating glass perspective window 13 manually. In addition, Voice command can realize the accurate control that glass is had an X-rayed window 13 lifting position, and user can have an X-rayed window 13 by phonetic order by glass and rest in any position; Have employed the mode of earphone-microphone Voice command, embody the advantage of safety and intelligent control. When having burning or explosion potential when experimental subjects, user's personnel safety being constituted a threat to, at this moment just need experimenter away from cabinet, Fume Hoods is carried out remote control, have the demand of radio communication, this is exactly the advantage adopting earphone-microphone 18. When testing, user's both hands are often stained with various chemical article, reagent, are not easy to each parts to Fume Hoods and operate, and adopt the scheme of Voice command, it is ensured that the outside clean and tidy health of Fume Hoods. Generally, whole Fume Hoods system and control method thereof embody the advantage of intellectuality, automatization.
When specifically implementing, user first the Keysheet module in control system integration panel 16 press button, open Fume Hoods, at this moment display module also starts, and display welcomes the environmental parameter of language and Fume Hoods such as temperature, air pressure, gas concentration etc. Open wireless headset again, then earphone-microphone 18 automatically mates with the wireless signal transmission module 28 in system integration panel 16 and is connected, and after successful connection, Controlling System automatically pushes and welcomes language to earphone-microphone 18, and earphone-microphone 18 is in wait instruction state. When needing control Fume Hoods to change running status, user sends voice control command by earphone-microphone 18, after wireless signal transmission module 28 reception, voice control command is transferred to speech recognition module 27, audio collection module in speech recognition module 27 gathers voice control command information, the voice signal processing module being transferred in speech recognition module, voice control command information is converted to electrical signal and is transferred to controller by voice signal processing module. Controller receives electrical signal and makes corresponding actions according to content-control Fume Hoods, such as controls glass perspective window and rises, declines, stops; Blower fan rotates acceleration, slows down, stops; Illuminating lamp tube opening and closing etc. In the process, the operation of Fume Hoods is all completed by user by phonetic control command, and this, with regard to having vacateed bigger space to the both hands of user, allows user can be absorbed in experimental subjects completely with both hands.When user needs to stop experiment, end instruction is sent to Fume Hoods by earphone-microphone, each module of Fume Hoods is (as window closedown, blower fan closedown, illuminating lamp tube closedown, display module closedown etc. completely automatically had an X-rayed by glass) out of service successively, after waiting that Fume Hoods is normally closed, earphone-microphone also stops work. So far, whole embodiment process all terminates.
More preferably, the Wireless Transmitter that described earphone-microphone 18 comprises earphone, microphone is all connected by signal wire with earphone and microphone, it is transported to the communication module set by cabinet of Fume Hoods by transmission over radio after voice collecting, and it is identified as corresponding instruction, and then realize glass perspective window, blower fan and the illuminating lamp tube of Voice command Fume Hoods, realizing the Voice command of Fume Hoods, avoid the hand touching Fume Hoods that user's experimentation stains, preventing pollution ensures the outside clean and tidy health of Fume Hoods.
More preferably, described Wireless Transmitter carries out communication by bluetooth with described wireless signal transmission module 28 and is connected, it is also possible to carry out transmitting voice signal by other transmission over radio agreements, it is achieved human-computer interaction controlled in wireless directly controls Fume Hoods.
More preferably, described wireless signal transmission module 28, speech recognition module 27, controller 25 and display module 26, Keysheet module 29 forming control system integrated panel 16. Described control system integration panel 16 comprises controller (CPU), Keysheet module, display module, the motor driving circuit of glass perspective window, lamp tube drive circuit 22, fan drive circuit, makes corresponding state for the electrical signal control Fume Hoods according to voice control command and changes.
Above disclosed being only the preferred embodiments of the present invention, certainly can not limit the interest field of the present invention with this, the equivalent variations therefore done according to the present patent application patent scope, still belongs to the scope that the present invention is contained.
