Label is 1- metering system, 2- control system, 3- data background terminal, 11- liquid barrel, 12- pump, 13- stream in figure
Meter, 14- liquid valve, 15- bowl, 16- check valve, 21- singlechip controller, 22- power supply.
Specific embodiment
The following further describes the present invention with reference to the drawings.
As shown in Figure 1, the present invention includes metering system 1 and control system 2, the metering system 1 include by pipeline according to
Secondary connected liquid barrel 11, pump 12, flowmeter 13 and liquid valve 14, each component phase of the control system 2 and metering system 1
Even, control system 2 carries out analytical calculation, control pump 12 and liquid valve to the signal that flowmeter 13 is fed back by particular data model
14 opening and closing, to realize the accurate control of fluid flow.Fluid flow is calculated using flowmeter 13, it is opposite with title
Double recipe formula structure is simpler, it is not easy to error occurs, flowmeter 13 is placed between pump 12 and liquid valve 14, stream is reduced
The pressure difference of flowmeter 13 liquid feeding end and outlet end, can greatly improve the reliability and precision of measurement when meter 13 starts.
The control system 2 include singlechip controller 21 and power supply 22, singlechip controller 21 and pump 12 control terminal,
13 signal end of flowmeter, 14 control terminal of liquid valve are connected.It is controlled using single-chip microcontroller, program is simple, and reliable and stable.
Further, it is additionally provided with data background terminal 3 outside the control system 2, data background terminal 3 is responsible for single-chip microcontroller control
Then signal is fed back to singlechip controller 21 and carried out to each component of metering system 1 by the data collection of device 21 processed and processing
Control.Data background terminal 3 is provided simultaneously with online payment function and big data processing function, can guarantee singlechip controller 21
It safely and steadily runs.
The process of selling of the invention is: after singlechip controller 21, which receives, to be sold signal and sell capacity, successively
Starting pump 12 and liquid valve 14, carry out out liquid, and flow signal is fed back to singlechip controller 21, single-chip microcontroller control by flowmeter 13
Device 21 is calculated according to the feedback signal of flowmeter 13 by particular data model, and judgement reaches singlechip controller 21 and connect
Receive when selling capacity, close liquid valve 14 and pump 12, completion sell process.Pump 12 should first be started when starting, restarted out
Liquid valve 14 can reduce the pressure at 13 both ends of flowmeter, guarantee the measurement accuracy of flowmeter 13；Liquid valve should be first closed when closing
14, pump 12 is turned off, because the stalling of pump 12 needs certain time, first closing liquid valve 14 can play the role of retaining in time,
Avoid occurring air in pipeline.
Further, this system also has the audit function of liquid, and particularly, the liquid barrel 11 is quantitative filling
Bucket, singlechip controller 21 can store each amount of selling, and determine that liquid barrel 11 will when singlechip controller 21 calculates
When selling light, the informing of data background terminal 3 can be sent the signal to and need to change bucket.
The liquid barrel 11 is sealing bucket, and bung hole is equipped with the check valve 16 inside connection liquid barrel 11.Sealing bucket 11 can
It is contacted for a long time with air to avoid the liquid in bucket, influences liquid quality, 16 permission air of check valve enter bucket outside bucket
It is interior, so that liquid is pumped away.Check valve 16 can also carry out control opening and closing by singlechip controller 21, when system breaks down
When, check valve 16 can be closed, liquid is prevented to be sucked away, to play a certain protective role.
After the replacement for completing liquid barrel 11, it is possible to will appear air in pipeline, in order to not influence selling, needs to be discharged
Air in pipeline, it is necessary first to one bowl 15 be set in the exit of liquid valve 14, when the new replacement of liquid barrel 11 finishes
Afterwards, start exhaust process, singlechip controller 21 receives signal, and starting pump 12 opens liquid valve 14, and flowmeter 13 is by flow
Signal is sent to singlechip controller 21, and singlechip controller 21 passes through particular data model according to the feedback signal of flowmeter 13
It is calculated, when determining flow value needed for reaching preset exhaust, closes liquid valve 14 and pump 12, institute's discharging liquid is injected into
In bowl 15, it is shown by sample.
The metering method of the metering system, mainly comprises the steps that
A, singlechip controller receives the weight or volume of required class of liquids from user input, required liquid,
And weight or volume is converted into flow；
B, singlechip controller compares received signal and background data base, and whether the liquid in inspection liquid barrel
Enough amounts, liquid abundance carry out going out liquid step below, and liquid not enough then reminds user concurrent signal to change to the prompting of data background terminal
Bucket；
C, fluid low and after changing new bucket, single-chip computer control system detects signal, opens pump and liquid valve, flowmeter
Flow signal is sent to singlechip controller, singlechip controller passes through particular data model according to the feedback signal of flowmeter
It is calculated, when determining flow value needed for reaching preset exhaust, closes liquid valve and pump, complete exhaust process；
D, it carries out selling process after liquid abundance or exhaust process, singlechip controller controls pump work, opens out
Liquid valve carries out out liquid, and cmf record Data Concurrent gives singlechip controller and carries out operation and real time contrast, when judgement reaches
When selling capacity received by singlechip controller, closes liquid valve and pump is completed to sell process.
Due to user be usually when buying liquid according to weight or volume determine purchase volume, so system firstly the need of
Weight or volume is converted into the flow signal that flowmeter can identify, singlechip controller upon receipt of the signals can first into
One checking step of row, determines whether the liquid of liquid barrel is enough measured, and amount not enough then signals to data background terminal and reminds work
Personnel change bucket and remind user, and enough amounts then carry out out liquid step.Every time after having replaced new bucket, require once to be vented
Journey, guarantee pipeline in it is hydraulically full always, improve the measurement accuracy of flowmeter.
The present invention realizes the flow measurement of liquid using flowmeter and singlechip controller, relative to traditional poidometer
Amount mode, structure is simpler, measures more accurate, and is influenced by extraneous factor smaller, can be widely used in high-precision liquid
Field is sold, there is good practicability and application prospect.
