Abstract
A kind of method for controlling liquid injection.Mode of operation and dutycycle are selected by button first, dutycycle is ratio of the theoretical liquid injection rate with vessel volume under automatic mode.Then container is placed, mode of operation judgement is carried out after system senses container, if in manual mode, the manually controllable liquid injection of user；If in automatic mode, first measuring container height and recording, container height is multiplied with dutycycle and obtains theoretical liquid level, then begin to inject liquid, monitoring liquid level is started simultaneously at, when liquid level reaches theoretical liquid level, stop injection liquid, so far liquid injection is finished.This method can select mode of operation as needed, simple to operate, while judging vessel volume and automatically adjusting liquid injection rate, flexibility is good.
Description
Technical field
The present invention relates to the method for control liquid injection, liquid injection rate can be especially automatically adjusted according to vessel volume
Control method.
Background technology
At present, the injection of control liquid is main is realized by physical switch, controller timing and infrared liquid level sensor.
But, physical switch control method needs artificial participation control, and easily causes the problems such as liquid overflows in use；Control
Device time control method processed makes device that specific container can only be coordinated to be used, and can be mismatched using other containers, cause liquid
The problems such as body overflows or injection rate is too small；Control system based on infrared liquid level sensor easily by other objects send it is red
The interference of outside line, stability is poor, and can not adjust liquid injection rate, very flexible.
The content of the invention
In order to overcome the shortcomings of that cumbersome, very flexible and the degree of accuracy are low in existing control liquid inpouring method.This
Invention provides a kind of method for controlling liquid injection, and this method can automatically adjust the injection rate of liquid according to vessel volume.
The technical proposal for solving the technical problem of the invention is：
A, in use, selecting mode of operation by button first, mode of operation includes dutycycle, under dutycycle is automatic mode
Theoretical liquid injection rate is with the ratio of vessel volume, if approximately regarding container as cylinder, dutycycle can regard liquid level as
With the ratio of container height, theoretical liquid level can be obtained by being multiplied by the value with container height；
B, container is then placed, mode of operation judgement is carried out after system senses container；
If c, be in manual mode, the manually controllable liquid injection process of user；
If d, be in automatic mode, measure container height and record, container height is obtained into theoretical liquid with dutycycle multiplication calculating
Face highly, starts to inject liquid, while monitoring liquid level, when liquid level reaches theoretical liquid level, stops injection liquid.
The beneficial effects of the invention are as follows：Mode of operation is selected according to the actual requirements, it is simple to operate, can be according to vessel volume
Liquid injection rate is automatically adjusted, flexibility is good.

B, placement container；
C, judge mode of operation；
If d, being in manual mode, user controls liquid to inject manually；
If e, be in automatic mode, measure container height and record；
Container height is obtained into theoretical liquid level with dutycycle multiplication calculating；
Start to inject liquid；
Monitor liquid level；
If liquid level reaches theoretical liquid level, stop injection liquid.
In fig. 2, system is by water injection pipe（7）, electrically operated valve（6）, pressure sensor（8）, button（5）, processor（9）、
Stepper motor（10）, laser beam emitting device（1）, laser receiver（2）Composition；
A, processor（9）Coordinate various parts work；
B, pressure sensor（8）Experience the placement situation of container, container is in pressure sensor（8）Upper generation pressure, pressure sensing
Device（8）Electric signal is produced after perceiving and is sent to processor（9）；
C, water injection pipe（7）And electrically operated valve（6）Control the injection of liquid, processor（9）Electric signal is sent to electrically operated valve（6）,
Control it to open and turn off, and then control water injection pipe（7）Switch；
D, button（5）Realize man-machine interaction, people's pressing keys（5）Afterwards, button（5）Produce electric signal and deliver to processor（9）, processing
Device（9）Judge that signal type selects mode of operation；
E, stepper motor（10）Control laser aid（1、2）Movement, processor（9）Pulse signal is produced to stepper motor
（10）, stepper motor（10）Rotate and then moving laser device（1、2）；
F, laser aid（1、2）To detect media variations, processor（9）Electric signal is produced to send to laser beam emitting device（1）,
Start simultaneously at timing, laser beam emitting device（1）Launch laser, laser is through Medium Propagation to laser receiver（2）, laser pick-off
Device（2）Receive after laser, produce electric signal to processor（9）, processor（9）Stop timing, if medium changes, swash
The spread speed of light will change, and the resulting propagation time can also change.
In figure 3, step is as follows：
After a, system energization, equipment initialization, stepper motor playback, pressure sensor（8）Reset, electrically operated valve（6）Close, swash
Light device（1、2）Transmitting Laser Measuring obtains the time TIME_AIR that now laser is propagated in atmosphere；
After b, initialization are finished, pressing keys（5）Mode of operation is selected, waits container to place；
After c, container placement are finished, pressure sensor（8）Pressure change is experienced, electric signal is produced and sends to processor（9）, open
Beginning mode of operation judges；
If d, system work in a manual mode, pass through pressing keys（5）Open electrically operated valve（6）, unclamp button（5）It is electronic afterwards
Valve（6）Close, simultaneity factor returns to mode of operation selection state；
If e, being operated in automatic mode, processor（9）Send pulse signal control stepper motor（10）Rotate, it is ensured that Laser emission
