Background technology
The method of controlling now flow is generally that flow velocity is multiplied by the time, but flow is discrete sometimes, need to drop by drop drip, how to control the number that drips in the unit interval, not not to be just easy to so, people have also used a lot of ways, last many not successes, wherein reasonable way is to count with laser, when liquid falls down one, just obstruct the light once, optical-electrical converter will perceive, produce a pulse, count, pass through again feedback circuit, just can control and drip number, but such be designed with a lot of shortcomings, high cost, design is large, if being stained with liquid or booty on transparent wall just can not use, drip on kettle if be used in often will change, installing is also a great problem, also has a lot of problems, so also generally do not use now.
Summary of the invention
There is no now good way owing to controlling to drip to count, we have designed a lot of methods and have done test, have done test many times, and we finally find a kind of basic law, in the time that drop falls down, can give reverse impulse force of tube for transfusion.A kind of drop counting and Based Intelligent Control are dripped to several methods, when liquid is along pipe toward dirty, when flow is inadequate or pressure is too small, liquid will form drop at tube head, due to the active force between liquid, the tension force effect on drop surface, the active force of liquid and tube wall, make the volume and weight of drop slowly become large, above gravity is greater than active force and, drop just falls down, at this moment due to the active force between liquid, the tension force effect on drop surface, the active force of liquid and tube wall, will produce a recoil strength, sensor will perceive this recoil strength, can produce an impulse wave, drip several and will produce several impulse waves, amplify by sensor internal, information is passed to microprocessor, pass through microprocessor processes, microprocessor will be recorded several impulse waves in the unit interval, Here it is to stalagmometer number, if the value of the pulse wave number in the unit interval is greater than the value of dripping number in original setting unit interval, microprocessor makes flow regulator by the slack-off pin voltage of flow will to one of peripheral circuit, holding time of this voltage is the base's time that deducts original setting and drip several values and be multiplied by setting according to the value of the wave number that measures, so the value of wave number and setting are dripped the value difference of number apart from larger, the time regulating is longer, what close is just more, the number that drips that will be adjusted to original setting slowly, if the value of the pulse wave number in the unit interval is less than the value of dripping number in original setting unit interval, microprocessor will be given pin voltage that flow regulator is accelerated by flow of peripheral circuit, holding time of this voltage is base's time of setting value that the value of dripping number deducts the wave number measuring and be multiplied by setting according to original, so the value difference of wave number and setting is apart from larger, the time regulating is longer, that opens is just more, the number that drips that will be adjusted to original setting slowly, count with regard to dripping of intelligent control liquid like this.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram that drop counting and Based Intelligent Control is dripped to counting method, the container of 1 representative dress liquid, and 2 represent the tube for transfusion of top with branch, 3 represent drop, and kettle is dripped in 4 representatives, and 5 represent the tube for transfusion of following, the 6th, flow regulator, 7 sensors, 8 microprocessors and interlock circuit.Fig. 2 is the impulse wave that sensor produces, and the signal that sensor produces, through amplifying and DC-isolation, will produce the waveform of Fig. 2, and 1.2.3. represents waveform.
