Description
Technical field
The present invention relates to electrochemical field, particularly relate to a kind of multi-functional chemical liquid dispensing device.
Background technology
In today of electron trade fast development, the application of electronic instrument and embedded technology has greatly increased the efficiency of social industry-by-industry.And as school and research institute, the high concentration district of social knowledge, electronic instrument and embedded technology have become a kind of requirement.For this reason, we just should expect in every aspect the efficiency improving us with them.
For college student and the research institute office worker of applied chemistry, chemical dosing is an indispensable ring in all kinds of chemical experiment, an important indicator of its precision chemical experiment especially.Although artificial dosing can meet a lot of experiment along with the growth of experimenter's experience, its precision is still not too optimistic, and a lot of aspect all also needs to improve and estimate.
For this situation, the chemical liquid dispensing device of a kind of intellectuality, efficient activity urgently occurs.So just can save many manpowers, energy and time, also can greatly improve dosing precision, avoid the many human errors brought to chemical experiment by artificial dosing mode.
Summary of the invention
For solving the problem, the invention provides a kind of multi-functional chemical liquid dispensing device, greatly can alleviate the burden of chemical experiment personnel, and stop the human error in chemical experiment in the past well.
Technical scheme of the present invention is, provide a kind of multi-functional chemical liquid dispensing device, this device comprises controller unit, touch screen unit, Flash memory cell, dosing activating terminal system and dosing control terminal system.Above-mentioned dosing activating terminal system is comprised plunger displacement pump unit, stepper motor unit and pipeline transfer valve unit and is connected with sample and dilution by pipeline; Above-mentioned dosing control terminal system comprises driving stepper motor unit, plunger displacement pump driver element is connected with controller with photoelectricity door detecting unit.
Driving stepper motor unit of the present invention, is made up of stepper motor driver chip and peripheral circuit, and changes arbitrarily the segmentation of stepper motor by toggle switch.
The multi-functional chemical liquid dispensing device of one of the present invention, is mainly used in the Scientific Research in University Laboratory research institute relevant with applied chemistry.Device take touch-screen as medium, and chemical experiment personnel (comprising Faculty and Students) can carry out the relative parameters setting of chemical complicated dosing by touch-screen, conveniently complete each technical indicator of chemical dosing.Each chemical experiment personnel can preserving when time chemical dosing is arranged oneself.The present invention can add and delete the data (comprising volume, match ratio and cycle-index etc.) that certain dosing is arranged easily.
Touch screen unit of the present invention, completes man-machine interface easy and simple to handle.Display interface provides the edit boxes such as syringe volume, sample cell volume, extension rate, dilution volume, sampling amount, injection volume, injection speed, sample rate, cycle-index to select for experimenter, corresponding numeric keypad can be ejected after touching edit box and carry out data inputting for experimenter.
When there being chemical experiment personnel to need dosing, by operation touch-screen, the related data of dosing is inputted, if invalid, eject the warning dialog box, the related data of dosing write Flash stores by controller on the one hand, is the pulse of control step motor on the other hand by the data transformations that user inputs.If what experimenter configured at circulation edit box is nonzero digit, then realize automanual circulation, user needs to press trigger key on touch-screen to realize each circulation; If the parameter that experimenter configures at circulation edit box is " 00 ", then realizes Full-automatic circulation, do not need human intervention, but experimenter can force to stop circulation as required.Controller sends corresponding pulse to drive plate by the configuration information reading experimenter, the speed of injection and sampling can arrange separately by experimenter, controller can select correspondingly pulse frequency to control, and then control showing with relevant animation is on the touchscreen carried out to pipeline transfer valve and plunger displacement pump, the progress of prompting chemical experiment personnel this dosing, last chemical experiment personnel are by this dosing numerical nomenclature and file.
The present invention can simplify chemical experiment process, makes it automation, intelligent, and then improves conventional efficient.Because the present invention uses touch-screen to realize man-machine interaction, mode to chemical dosing setting and dosing process visualization, the error rate of artificial input greatly can be reduced.
Accompanying drawing explanation
Fig. 1 is the system block diagram of the embodiment of the present invention.
Detailed description of the invention
With reference to figure 1, a kind of multi-functional chemical liquid dispensing device, comprises touch-screen (5), Flash stores (4), controller (3), dosing control terminal system (2) and dosing activating terminal system (1).When chemical experiment personnel need dosing, the related data of dosing is entered into controller (3) by touch-screen (5), by controller (3), data are saved in Flash again and store (4), then control impuls is sent to dosing control terminal system (2) by controller (3) again, dosing control terminal system (2) controls dosing activating terminal system (1) according to the control impuls received, and dosing process is shown to touch-screen (5) by last controller (3).
Touch screen unit completes the typing of the parameters of experimenter.
Flash memory cell completes the preservation of experimenter's parameters.
Controller unit complete the reading of parameter on touch-screen and touch-screen display, to each control driven and to the collection controlling feedback information.
Driving stepper motor is used for control step motor, thus reaches the effect controlling pipeline transfer valve.
Photogate for detecting the turned position of stepper motor, thus reaches the object of the valve switch of testing pipes transfer valve.
Plunger displacement pump drives the accurate movement for controlling plunger displacement pump.
Plunger displacement pump is for realizing suction and the injection of sample.
By the way, the invention provides a kind of multi-functional chemical liquid dispensing device, be mainly used in, in the Scientific Research in University Laboratory research institute relevant with applied chemistry, greatly to alleviate the burden of experimenter; The present invention adopts the mode of touch-screen to realize man-machine interaction, to chemical dosing setting and dosing process visualization, can reduce or stop the mistake of artificial input.
