Description
Technical field
The present invention relates to a kind of conversion of Morse code and visualization devices, especially a kind of to be controlled by receiving Morse code signal
Cross type microchannel processed generates the device that various sizes of drop is combined into corresponding Morse code.
Background technology
Morse code invention is put in order by the difference between point, cross in 19th-century to express different English alphabets
And number.Morse relies only on the radio signal of a stable invariable tone, so its telecommunication equipment is compared with it
His mode is simpler, and it can strong noise, low signal environment in use.Meanwhile it only needs very narrow bandwidth, and
And may also help in two mother tongue differences, the operator of great difficulty can be encountered when traffic communicates between link up, in nothing
The fields extensive applications such as line electric signal transmission, electronic information transmission.
In today, international morse code is still used, and until 2003, International Telecommunication Union (ITU) managed
Morse code practician all over the world obtains the work of ham radio license.It is national at some, the one of ham radio
A little wave bands are still only reserved to send Morse code signal.
Microflow control technique refers to using microchannel(Size is tens of to hundreds of microns)Processing manipulates minute fluid(Volume
A Sheng is arrived for nanoliter)Involved Science and Technology is one and is related to chemistry, fluid physics, microelectronics, new material, biology
With the emerging cross discipline of biomedical engineering.Because have many characteristics, such as micromation, it is integrated, micro fluidic device is commonly known as
Micro-fluidic chip, also referred to as chip lab.When immiscible two kinds of liquid(Oil and water)When being flowed in microfluidic channel,
Under the action of liquid/liquid interface tension and shearing force, wherein one phase flow is known from experience to form highly homogeneous cutout, i.e. drop.It is micro-
Flow control can prepare the drop lotion of high degree of monodispersity with very high flux.
Morse code signal and microflow control technique are combined by the present invention, are handed over the Morse code signal received to control cross
The unlatching of continuous phase fluid inlet micro-valve and closure in forked type micro-fluidic chip, different length are intermittently generated to control in microchannel
The dispersed phase fluid drop of short size passes through the change of length drop in microchannel come " point " and " cross " being analogous in Morse code
Combination is changed, the Morse code consistent with signal is received is generated, to achieve the purpose that signal is received and converted.Relative to traditional Morse code
Method of reseptance, it is easier to realize the advantages such as quick, efficient that information is transmitted, and easily operated control.
Invention content
The present invention be to provide for it is a kind of based on cross type micro-fluidic chip Morse code conversion and visualization device, lead to
Cross and receive the size that Morse code signal carrys out in control channel to generate drop, to formed in microchannel be similar to " point " with
" cross " continuous phase fluid column reformulates corresponding Morse code to reach the reception of Morse code signal, conversion and visual purpose.
To achieve the above object, the technical scheme is that:A kind of Mo Si based on cross type micro-fluidic chip
Code receiving converter, including cross type micro-fluidic chip, wireless signal receiver, the micro-fluidic core of cross type
Microchannel one end of piece is equipped with dispersed phase fluid feeder connection, and other one end is exported equipped with microchannel, and microchannel cross end is set respectively
There are the feeder connection of continuous phase fluid, dispersed phase fluid entrance that micro-valve is installed, micro-valve is connected with wireless signal receiver, by
Wireless signal receiver receives Morse code signal to control the closure of micro-valve and unlatching at dispersion fluid feeder connection, is controlled with this
The length of drop in microchannel processed makes to generate corresponding length drop in microchannel, in length drop analogy Morse code
" cross " arranges out the Morse code signal consistent with signal is received with " point ", realizes that signal is received and converted.
The radio Morse code signal that the wireless signal receiver receives is converted to corresponding current potential by receiver to be believed
Number, when micro-valve receives high potential signal, the micro-valve is opened, and disperse phase liquid fluid injects microchannel through micro-valve, works as micro-valve
When receiving low potential, the micro-valve is closed, and does not have dispersed phase fluid injection in microchannel, and the time opened by micro-valve is controlled
Make the size length of the dispersed phase fluid drop generated.
The beneficial effects of the invention are as follows:Connected to control in cross type micro-fluidic chip with the Morse code signal received
The unlatching of continuous phase fluid inlet micro-valve and closure, to control the dispersed phase fluid for intermittently generating different length sizes in microchannel
Drop is combined come " point " and " cross " being analogous in Morse code by the transformation of length drop in microchannel, is generated and is received letter
Number consistent Morse code, to achieve the purpose that signal receives and conversion.Relative to traditional Morse code method of reseptance, it is easier to realize
The advantages such as quick, efficient that information is transmitted, and easily operated control.
Description of the drawings
Fig. 1 is that the Morse code based on cross type micro-fluidic chip receives conversion and visualization device schematic diagram.
Specific implementation mode
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, the Morse code receiving converter based on cross type micro-fluidic chip of the present invention, including ten
Word chiasma type micro-fluidic chip, micro-valve 3, wireless signal receiver 4.Microchannel one end of cross type micro-fluidic chip is equipped with
Dispersed phase fluid feeder connection 1, other one end are equipped with microchannel and export 7, and microchannel cross end is respectively equipped with the logical of continuous phase fluid
Road entrance, dispersed phase fluid entrance 1 are equipped with micro-valve 3, and micro-valve 3 is connected with wireless signal receiver 4, by reception of wireless signals
Device 4 receives Morse code signal to control the closure of micro-valve 3 and unlatching at dispersion fluid feeder connection, is controlled in microchannel with this
The length of drop makes to generate corresponding length drop in microchannel, be arranged with " cross " and " point " in length drop analogy Morse code
The Morse code signal consistent with signal is received is listed, realizes that signal is received and converted.Wherein, the long drop generated in microchannel
5 are used for indicating that the "-" in Morse code, the short drop 6 generated in microchannel are used for representing " " in Morse code.
Now transfer process is received to the equipment Morse code to illustrate:Original Morse code wireless signal is connect by wireless signal
After receipts device 4 receives, it is converted into corresponding electric potential signal, the folding of micro-valve 3 is then controlled by the high low-potential signal exported.
"-" can all be converted into high potential with " " in original Morse code, and the high potential duration of "-" output is long, " " output
The high potential duration is shorter, and low potential is then exported receiving in intermittent time section of the "-" with " ".When exporting high potential,
Micro-valve 3 is opened, and in dispersed phase fluid meeting injection channel, will produce dispersed phase drop in the main channel of micro-fluidic chip;Work as output
When low potential, micro-valve 3 is closed, just only continuous phase fluid injection in channel.It is controlled by original Morse code, what micro-valve 3 was opened
Time also can be different in size, therefore long drop and short drop can be generated in channel, and length drop is analogous to the "-" in Morse code
With " ", can be shown in main channel for the consistent Morse code arranged out by length drop of original Morse code information, it will be former
Beginning radio Morse code information visualization.
Such as show that by the Morse code that length drop indicates be "-" in microchannel in Fig. 1, it indicates
The meaning is English alphabet " B ".
