1, embeds the design of photo-electric detector technologies outward
Photo-electric detector and tube for transfusion are designed to outer embedded mounting structure.Its feature: a) photoelectric detector does not directly contact with fluid to be measured, and being does not have to infect to detect; B) it is fit to the real-time control circuit optimal design, and the electricity consumption device is few, economize on electricity; C) volume little, install and use efficient and convenient; D) cost of manufacture is low.
In the design, observe, find when liquid levels in the tube for transfusion descends with 20 low speed of per minute, to exist liquid concave surface degree of depth A still greater than the 0.3mm phenomenon by infusion.Know from optics that in addition concave mirror has scattering process to light beam.The liquid level of liquid is the same with concave mirror also to have scattering process to light beam.Therefore outside in the embedded photoelectric detector design, made full use of the physical characteristic of these two objective realities.At first select the direct-injection type photoswitch to do detection means, because it meets level detection and the outer technical characterictic that embeds the mounting structure design to transfusion.Under the condition of control circuit and detector opto-electronic conversion appropriate design, optical window physical dimension appropriate design to effective emissive surface of liquid concave surface and photoswitch, photoelectric detector receiving terminal optical window is by the regional all standing of effective astigmatism of liquid concave surface, just can realize that to the transfusion level detection, therefore the emphasis of design is to determine photoelectric detection switch device optical window size.Comprehensive consideration also has in the design: 1) photoelectric detection switch device optical window physical dimension and processing technology difficulty are taken into account selection; 2) effective allowance of determining liquid concave surface emissive surface and photoswitch optical window size consider (luminous pipe end optical window with receive pipe end optical window horizontal vertical alignment deviation and all influence light energy, optical window physical dimension a, b value are little, effectively allowance is big, but easily produce horizontal vertical alignment deviation, light energy is reduced; A, b value are big, and effectively allowance is little, are prone to the error of liquid level Photoelectric Detection, and this direct-injection type photoswitch of selecting before being can not direct applied reason); 3) luminous tube operating current and the economize on electricity in the photoelectric detection switch device considered.4) the light dark situation of Photoelectric Detection needs needs shading measure design.
In design and experiment: liquid concave surface degree of depth A value (it is slow more to drip speed, and A is more little for the liquid concave surface degree of depth, selects a low fast A value, can ensure that the vertical direction Photoelectric Detection is reliable) when getting 20 of per minutes and dripping speed slowly.The direction of motion of liquid level is gravity direction, and emission light end, the reception light end optical window size a value of therefore getting the photoelectric detection switch device are 0. 25-0.35mm.It can satisfy astigmatism (covering) the detection requirement of transfusion liquid level to its vertical direction.The a value is more little, and the processing technology difficulty is big more, and therefore generally getting a is 0. 3mm, is beneficial to processing technology.Luminous tube operating current value in the photoelectric detection switch device in addition, during Photoelectric Detection, detect the tube for transfusion at position and the transmittance problem that there is decay transillumination light intensity in internal liquid thereof, value can not be too little, consider control circuit the luminous tube operating current of detector is taken into account requirement mutually with economize on electricity, determine that the light emitting diode operating current lowest limit in the photoelectric detection switch device is 8mA.Like this, in a, b in the detector design, these three essential important parameters of determining of light emitting diode operating current, have only optical window size b value not determine, thus with it as experimental variable.In the experiment, change optical window size b value at every turn, all transfusion liquid level (20 of per minutes drip fast condition slowly) is carried out Photoelectric Detection and switch experiment.When getting optical window b=0.5mm, the transfusion liquid level can satisfy the scattered-light detection requirement of horizontal direction infrared light beam and effective allowance, is beneficial to technology again and makes.Determine newly-designed photoelectricity testing part technical parameter at last: luminous tube operating current 8mA is above, a=0.3mm, b=0.5mm.
After tube for transfusion embeds detection place of detector, the detector installing port is dorsad under sunlight, horizontal positioned, the solar radiation detector condition, light receiving tube forward DC resistance when detector does not power up is greater than 700k ohm, and it is that control circuit is realized the primary condition that opto-electronic conversion is reached by this shading design.Therefore designed upper and lower shell to new photoelectricity testing part packing, housing selects dark dark as the shading measure, synthetic window has solved optical window size b, and last and new photoelectric detection switch device is combined into the optical window of designing requirement: a=0.3mm, b=0.5mm.
To embed the photo-electric detector design outward and become absolute electrode formula structure, five pin plugs, flat wire are done connector, and flat wire one end is connected, is beneficial to the combination installation with the photoelectricity testing part pin for convenience, and having designed the connection compoboard again is two-sided deposited copper circuit board.At last make complete outer embedding photo-electric detector by shell, five pin plugs, flat wire, connection compoboard, photoelectric detection switch combination of devices.In enclosure designs, its structure technology feature is the design core in the shading measure, and it has solved the light dark condition that opto-electronic conversion requires when detecting the optical window that requires, level detection and has embedded installation question outward.It is outer one of the photo-electric detector core design that embeds.
2, control circuit art designs:
Control circuit is made up of logic control element and other electrical part of design, and it is to detect control circuit (after on and off switch closed, detector was in the detected state of switching on always) in real time.Characteristics: be fit to the occasion of the actual transfusion of transfusion time length difference (different people, the different causes of disease, different transfusion speeds), can detect at any time, save to economize on electricity and timing circuit is set and is beneficial to control circuit optimization.In the control circuit design, by the control circuit logical design, on and off switch K1 and operating switch K2 button are as function key, and two key selectivitys use, and can do the sound equipment auth-prompt to infusion audiomonitor work unlatching, line under-voltage, connector connection status or the like.Substituted the function of finishing by the exemplary functions circuit with the music discrimination method.Can save the side circuit that power supply indication (the transmitting tube work power consumption of the light emitting diode power consumption of doing the power supply indication in the detector), line under-voltage warning etc. need be set up again.Obviously simplify circuit, reached the design effect that used electrical part is few, economize on electricity, reduce cost of manufacture.
The control circuit design at first is designed to the detector output status signal numeral (switch) signal, is realized by the detector that designs and the R1 in the circuit, R2 design load.Therefore designed the CMOS integrated circuit general, cheap with logic gates IC1 CD4011(, that static working current is little) be the real-time detection control circuit of main logic control element.Logic gates IC1 CD4011 is four or non--2 double input end gate circuit integrated packages that trailing edge triggers, its logic control element design: door 1-2 foot connects a 2-4 foot, door 1-3 foot connects a 2-5 foot, and door 1, door 2 are connected into bistable circuit.Door 3, door 4 are connected into not circuit respectively.The trailing edge pulse generating circuit that design is connected into by K2, R3 and door 2-6 foot unclamps after being pressed by the K switch 2 that can reset and can produce a trailing edge pulse.Design connect into by R2, door 3 (being connected into not gate), capacitor C another can produce the generation circuit of trailing edge pulse.When the colelctor electrode of detector light receiving tube and R2 junction point end output high level (this circuit design normal condition: 1 detector does not connect, and 2 light receiving tube light paths are blocked or liquid level when passing through), door 3 outfans produce a trailing edge pulse; Another kind of situation, colelctor electrode and R2 junction point end output low level (when photoelectric receiving tube is shone by enough energy infrared rays) when the detector receiving tube, door 3 output high level, the electric capacity both end voltage can not transition, produces a trailing edge pulse at a capacitor C and a door 1-1 foot link.Be connected to door 1-1 foot, door 2-6 foot in door 1 and door 2 bistable circuits that are connected into respectively by the outfan of two trailing edge impulse circuits of design, constitute a pair of logic switching circuit (being simple logic control element).These two trailing edge pulse generating circuits of design and door 1, door 2 are connected into bistable circuit and form logic control element, it is the significant design of real-time control circuit, it plays a decisive role to the function optimization of control circuit, such as: realize substituting the function of finishing with side circuit with the sound equipment identification method.Logic control element acts in control circuit: power turn-on K switch 1, luminous tube in the detector gets the electric infrared ray of launching, light is through optical window directive photoelectric receiving tube light target, after photoelectric receiving tube is subjected to light, it is low resistive that its collection-radio electrode resistance is, it and R2(design set point value) component voltage in circuit is similar to 0v, and promptly the current potential of photoelectric receiving tube colelctor electrode and resistance R 2 junction points is a low level.At this moment door 3 outfans that are connected into not gate are high level, because of capacitor C two ends charging voltage can not transition, (door 3 outfans produce one and fall behind trigger impulse to produce a trailing edge trigger impulse at a door 1 and 2 door 1 trigger end 1 foot that are connected into bistable circuit, revert to high level), make door 2 outfans 4 feet be low level and keep by logical relation, at this moment door 4 outfans that are connected into not gate are high level, T1, Ic2, buzzer work, sound equipment.When needs buzzer sound equipment stops, a door 2-6 foot must obtain a trailing edge pulse-triggered (lifting out after pressing K2), makes the upset of a door 2-4 foot outfan for high level and keep.At this moment door 4 outfans upset is low level, and T1, Ic2, buzzer quit work, and sound equipment stops.Be low level if need door 2-4 foot outfan to overturn once more, have only opposite house 1-1 foot to add a trailing edge pulse-triggered, the output of door 2-4 foot could be low level and be kept by the high level upset.Can add that there are two kinds of situations in a trailing edge trigger impulse at door 1-1 foot: 1 detector detects a transfusion liquid level to be passed through, and receives optical window and is covered by the liquid level emissive surface.2 power cutoff K switch 1 are closed again.Can be drawn by the top logic control process that alternately triggers, control circuit logic working state is by on and off switch K1, operating switch K2 and the decision of detector output state three aspects.Therefore according to the used state of K1, K2, detector, being designed to substitute with the sound equipment differential method need the actual functional circuit of setting up.For example: detector and main frame patch state preliminary examination prompting (this function need be set up broken circuit detection circuit), and (sound equipment is not for the logical relation of usefulness the design circuit and sound equipment; Volume) cooperates, just can do multiple function preliminary examination to circuit, save the multiple actual functional capability circuit that needs setting with the sound equipment discrimination method.Patching the sound equipment discrimination process that detects prompting that opens circuit with main frame and detector below is example, and the sound equipment identification function design of audiomonitor is described.The control circuit design is at first set: press on and off switch k1, the audiomonitor sound equipment; Lift out after pressing operating switch K2, the audiomonitor sound equipment stops.This sound equipment variable condition illustrates in circuit: detector and main frame patch well, and detector and control circuit are normal.
Describe work process below in detail:
1) detector and main frame patch.Press on and off switch k1, luminous tube gets electroluminescence, light receiving tube is subjected to light, this moment, the current potential of light receiving tube colelctor electrode and resistance R 2 junction points was a low level, door 3 outfans that are connected into not gate are high level, and because of capacitor C two ends charging voltage can not become more, (door 3 outfans produce one and fall behind trigger impulse to add a trailing edge trigger impulse at door 1 trigger end 1 foot that is connected into bistable circuit with door 2, revert to high level), make door 2 outfans 4 feet be low level and keep by logical relation.Door 4 outfans that are connected into not gate are high level, T1, Ic2, buzzer work, sound equipment.Lift out after pressing operating switch K2 this moment, and door 2 inputs 6 feet are subjected to the trailing edge pulse-triggered, and door 2 outfans 4 feet are high level, and door 4 outfans that are connected into not gate are low level, and T1, IC2, buzzer quit work, and sound equipment stops.Front sound equipment change of state overall process has illustrated that control circuit, detector are normal, and detector and main frame patch well.
2) confirm that detector and main frame do not patch or do not insert.Press on and off switch K1, the photoelectric receiving tube colelctor electrode is in and opens circuit or do not have photoelectricity conversion (transmitting tube opens circuit not luminous), door 3 inputs and resistance R 2 junction point current potentials are always high level (foundations of resistance R 2 design values), door 3 outfans are low level, after 1 foot of door 1 trigger end produces a trailing edge triggering, keep low level constant always, make door 1 export high level always.Therefore, lift out after pressing operating switch K2, door 2 outfans 4 feet have one to uprise level and recover the low level process again, and the sound equipment of audiomonitor produces moment and stops or not phenomenon to ringing, this sound equipment state description control circuit is normal, detector and main frame patch bad or detector bad.Above sound equipment is differentiated can truly reflect audiomonitor related circuit or unit status.Because on and off switch K1, operating switch K2 use as function key again, real-time control circuit is at any time promptly with differentiating that saving power work shows setting by sound equipment.Ring not and the sound volume difference of sound equipment by sound equipment in addition, can make the sound equipment auth-prompt the control circuit power supply state.Such as the prompting of line under-voltage sound equipment, adopt the sound volume difference design to the control circuit sound equipment: the quantification design by silicon rectifier diode D1, buzzer, supply voltage triadic relation is finished.This audiomonitor power supply voltage 3V; Silicon rectifier diode D forward junction voltage drop 0.6V; Buzzer rated operational voltage 3V.When considering infusion, the environment that needs peace and quiet, so the design of the max volume of sound equipment can not be big, when supply voltage just often, supply voltage 2.4V on the buzzer, sound equipment is normal.When the audiomonitor supply voltage drops to 2v, the buzzer both end voltage be 1.4V(deduct seal in silicon rectifier two utmost point commutation diode D forward junction voltage drop 0.6V), acoustics volume reduces very big, whether the notable difference that utilizes this acoustics volume to change can identify power supply under-voltage, determines whether to change battery.Still can operate as normal when this monitoring circuit design is lower than about 2V power supply, though acoustics volume has significant change, do not influence detector and detect.
Be by use K1, K2 below, obtain the sound equipment auth-prompt of alternative functions circuit:
Main frame inserts the outer photo-electric detector that embeds
1) power turn-on K1, buzzer do not ring, and illustrate that power supply does not add or K switch 1, buzzer, control circuit have problem.
2) the power turn-on K switch 1, and buzzer sounds, and sound equipment just often illustrates that supply voltage is normal.
3) the power turn-on K switch 1, and volume is obviously little, and power voltage insufficient is described.
4) power turn-on K1, the buzzer volume is normal, but cuts in and out, and is that the battery contact is bad.
5) the power turn-on K switch 1, and buzzer resonant amount is normal, presses operating switch K2, and sound equipment stops, and illustrates that circuit is normal, and the detector connector patches well.
6) after the power turn-on K switch 1, press operating switch K2, the buzzer sound equipment does not stop, and illustrates that circuit existing problems or detector patch bad (whether normal inspection patch or K2 has problem).
By top sound equipment prompting as can be seen, the sound equipment auth-prompt substitutes the design that the actual functional capability circuit is provided with, and saves that power supply powers up demonstration, line under-voltage, main frame and detector connection status, circuit state detects and for economizing on electricity actual functional capability circuit settings such as setting up timing circuit.
R1 in the circuit diagram is to be the current-limiting resistance of led designs in the detector specially.R2 is special resistance for light-operated switch condition design, and the adaptive choosing value of R1 and R2 can change the level detection of detector to transfusion transmittance difference.T2 is the power amplification audion of music integrated block IC 2.14 feet of CD4011 connect the power supply positive supply in the circuit, and 7 foot ground connection do not mark in the circuit diagram.
3, audiomonitor structural design
Audiomonitor is designed to host machine part and two parts of detector.For the layout of infusing is succinct, easy to install.
A) host machine part: form by host box, main circuit board, two batteries.Host box: host shell, bonnet two parts are combined into.Main circuit board: in circuit diagram except photoswitch (detection means) manufacture into embed outside the photo-electric detector, other electrical part all is welded on the circuit board.Use battery: No. seven.
B) detector: be designed to the outer photo-electric detector that embeds.
Beneficial effect of the present invention:
1) the outer photo-electric detector design that embeds: it is designed to outer mounting structure, the electric pole type overall structure by one's own efforts of embedding, make outer embed the photo-electric detector make small and exquisite, install replace convenient, power consumption is little, cost of manufacture is cheap.
