The specific embodiment
Below in conjunction with drawings and Examples work process of the present utility model is further described:
The operation principle block diagram illustrating is as follows: controller is mainly by dropping liquid signal detection importation, and circuit control section and machinery control three parts are formed.Wherein dropping liquid signal detection importation operation principle is described below: dropping liquid signal detection importation mainly comprises photoelectric sensor, filtering, shaping, amplifying circuit and signal indicating circuit, photoelectric sensor is made up of a pair of infraluminescence pipe and a pair of infrared receiving tube, because the optical characteristics of infrared receiving tube, its resistance changes and changes along with the power that receives light, and therefore the magnitude of voltage at the inclined to one side value circuit u place that forms with its also is subjected to the influence a little less than the receiving light power.During transfusion, the black Fei Shi pipe of transfusion device is installed on the photoelectric sensor, between a drop of liquid is through luminous tube and receiving tube, receiving tube is subjected to blocking of dropping liquid, and the light intensity of reception changes, and its resistance also changes, magnitude of voltage at inclined to one side value circuit u place also changes, thereby formed an impulse waveform,, also just formed several impulse waveforms at the u place if there is continuous a few drop of liquid to drip.The pulse that this place forms enters 2. foot of ic chip 555 the, through filtering, from 3. foot output, forms a rectangle square wave after the shaping, and input inverter IC2003 after anti-phase amplification, has obtained a jamproof complete counting pulse signal again.At this moment this signal is directly imported the external counting pulse input end P3.3 foot of single-chip microcomputer.Pulse after anti-phase amplification is a low level simultaneously, is sent to light emitting diode one foot in the signal indicating circuit, makes it luminous.So black Fei Shi manages each drop of liquid of inherent photoelectric sensor place when dripping, and singlechip CPU obtains a count pulse, and the light emitting diode in the signal indicating circuit all answer once glittering, represents that the dropping liquid signal normally receives.
The circuit control section is described below: the circuit control section comprises power circuit, self-checking circuit, button inputting circuits, display circuit, warning circuit, motor-drive circuit and chip microprocessor circuit.
Power circuit: controller adopts the 220V50Hz ac power supply, configuration one rechargeable battery set (4.8V/800Ah) in its machine, connect with the mains during charging and start shooting, at this moment alternating current power supply to the main frame power supply, also charges the battery on one side simultaneously, when having a power failure, self-contained battery work is automatically powered to controller, when internal battery will exhaust, voltage below 4.3V, the under-voltage indication of battery Flicker occurs, report to the police simultaneously, the machine intimate circuit voltage is about+5V.
Self-checking circuit: come closure state to tube for transfusion to detect by pressure transducer and position sensor during transfusion and the position of by-pass valve control is determined, pressure transducer is at the tube for transfusion front end, during work, by-pass valve control pushes tube for transfusion forward, after tube for transfusion is subjected to " axe shape " valve external force extruding and is in closure state, continue the squeeze pressure pick off again, when extruding force increases one regularly, pressure transducer sends electricity frequency signal and passes to singlechip CPU, single-chip microcomputer sends instruction, motor quits work, and by-pass valve control also stops extruding; Position sensor is located at the rear end of by-pass valve control, and during start, system carries out self check, the motor counter-rotating, and by-pass valve control moves back to the home position backward, and behind the trigger position pick off, single-chip microcomputer sends instruction, and motor quits work.
Button inputting circuits: mainly be that every infusion parameter is set, realize human computer conversation's function, form, be connected, can set transfusion drip speed, total amount, time, cast numerical values recited with single-chip microcomputer by key board and peripheral circuit.
Display circuit: by display, backlight and driver module are formed, content displayed is every infusion parameter, comprise that transfusion drip speed, total amount, time, transfusion cast, power supply symbol, battery symbol, duty, transfusion finish prompting and various transfusion failure codes etc., be connected with single-chip microcomputer and finish above-mentioned functions.
Warning circuit: adopt acousto-optic to report to the police simultaneously, when occur blocking in System self-test, the transfusion, transfusion is finished, battery is under-voltage and transfusion in have that unusual condition generation, display lamp send HONGGUANG, loudspeaker send alarm sound.
Motor-drive circuit: mainly by amplifier and drive chip and peripheral circuit is formed, during work, CPU sends level pulse through anti-phase amplification rear drive IC3 chip, and IC3 driving chip is exported the rotation that two groups of electric currents come the control step motor.
The chip microprocessor circuit: be the brain of controller, instruction control relative program after all data are collected comparison process here, and then is sent in programme controlled core.It mainly is made up of the 89C52 series and the peripheral circuit of 40 feet.
The machinery control section is described below: mechanical control section comprises motor and mechanical control structure.Motor is a motor, and mechanical control structure is made up of decelerator, rectangle slideway, by-pass valve control.Wherein the major axis on the decelerator is a screw rod, cooperate the nut that rotates to be embedded in the working of plastics by-pass valve control with screw rod, the by-pass valve control front end is " an axe shape ", the rectangle slideway is fixed on the decelerator iron plate, during the control transfusion speed, the moving gear train work that drives on the decelerator of motor positive and inverse is rotated, and by screw rod and nut work, drives by-pass valve control and steadily moves back and forth in the rectangle slideway.
The process of intelligent transfusion controller control transfusion speed is as follows:
At first the controller main frame is cooperated with suspension arrangement and be suspended on the drip stand, connect with the mains again, turn on the power switch, CPU and interlock circuit work are after showing appears in display screen, system carries out self check, machine enters set condition, after configuring transfusion drip speed on request, transfusion device is installed again, during installation, require black Fei Shi pipe dropping liquid normally to be received by photoelectric sensor.By behind " resetting " key, by-pass valve control detect tube for transfusion automatically forward and close after stop, at this moment decontroling the manual roller on the transfusion device again, press the " RUN " key after, machine begins to control automatically transfusion speed.At this moment, motor begins counter-rotating, driving by-pass valve control slowly moves backward, tightly open tube for transfusion, allow its liquid that normally drips, according to the detected dropping liquid signal of photoelectric sensor, single-chip microcomputer calculates the setting value that per minute drips behind the fast numerical value with memorizer and compares, relatively, according to positive negative error, send the rotating of pulse enable signal motor by single-chip microcomputer, the drive by-pass valve control advances or retreats, the infusion rubber tubing of its front end is compressed or is loosened, and it is accurately infused according to the parameter of setting.If transfusion speed is when " 1~8 droplet/minute ", adopted other kind of control mode, by-pass valve control is closed tube for transfusion always at ordinary times, when reaching certain hour, just open tube for transfusion one time, allow after its drop of liquid of dripping, close at once, when waiting next time, open tube for transfusion again one time, so just can accurately control transfusion speed apace.In the infusion process, when obstruction, emptying appear, when transfusion is finished, sound and light alarm appears in controller, and stops transfusion.
