Description
Technical field
The present invention relates to a kind of with sound, light, electric wave and other ripple class sensor that shakes constitutes certain working surfaces as required in breeding water body, the breed kind sensor that utilizes trip to go into is wherein responded to, through having frequency-selecting, Doppler effect detects, multistage counting, relatively, preset and temperature relay that microprocessor that the circuit of necessary miscellaneous function constitutes becomes to have heating element heater is judged to be and cultures kind and raise the nose above water to breathe or seek food, and report to the police automatically and the passive method of switch aerator or bait throwing in machine, and a kind of utilize removed and raised the nose above water to breathe the approximate oxygen consumption of this breeding water body in the unit interval of time reckoning for the first time according to the breed kind in above day and compare number intensity of illumination measurements on the same day back of adding up, thereby infer that roughly in a few days the floating head time reaches the active method of then reporting to the police automatically and starting aerator to the interior breed kind of this water body for the first time, also have and a kind ofly utilize small-power oxygenation facility to lure into to raise the nose above water to breathe fishes and shrimps etc. in set of sensors, increase the method for passive class self-con-tained unit reliability, three kinds of methods can comprehensively be used in combination, and can expand the branch state, remote alarms reaches the function of according to circumstances controlling multiple fishery machinery successively.
Technical background
Existing commercially available oxygenation automatic control and warning device are many to be monitoring target with the dissolved oxygen in water, and aquaculture now adopts the high density intensification to raise together with more, the physique of breed variety comes and go because of raise competence difference, if hypoxia-resistant capacity then descends very big especially when suffering from disease such as gill rot.Like this, the such device working value sets when higher that fishes and shrimps etc. have been raised the nose above water to breathe and device is failure to actuate, and working value arranges when on the low side that fishes and shrimps etc. are raised the nose above water to breathe and oxygen-increasing device has been opened, the waste function.And the in advance operation of oxygenation type commonly used can cause the in advance convection current of breeding water body levels, make the pond at the bottom of oxygen consumption more serious, in night in case shut down oxygen dissolving value with rapid decrease.Like this, be chosen in and open the generation that aerator could effectively cut down the consumption of energy and can prevent the harm of general pond when fishes and shrimps etc. have just been raised the nose above water to breathe.Other has with air pressure is that then malfunction is bigger for the oxygenation self-con-tained unit of monitoring target.With the method for microcomputer time controlled then need be set personnel's floating head time of the property guessed deduction fishes and shrimps etc. rule of thumb, the late problem of early opening is arranged out equally.More than device all is unable to cope with the accident floating head, and all can not monitor the floating head of being poisoned and being caused by water body.Device with the signal fish of feeding in the infrared probe monitoring water fish basket is arranged, this device all may be made a response to the anoxic and the floating head that causes of poisoning, but because of its " biology sensor " fixed-site with can be monitoring target with the signal fish only, the probability of happening of fortuitous event be still very big.May there be larger difference such as most of fish physique in signal fish and the water body, and also can be mutually far short of what is expected with the hypoxia-resistant capacity of hungry fish with the fish of being satiated with food of physique, this has just caused end user's the difficult problem of feeding.Everywhere noxious material distributes and inhomogeneous in the water besides, and this just makes this device more ineffective to the monitoring of this type of floating head (toxin that produces such as hydrogen sulfide at the bottom of the pond and the intensive place of algae).
The present invention is intended to improve the reliability and the accuracy of oxygenation self-con-tained unit, accomplish ultimate (fishes and shrimps floating head) and wide-angle (the big portion of water body and breed kind) monitoring, reduce the general pond danger of aquaculture and nurse personnel's working strength, also can help the raiser to accumulate data such as the local quantity of illumination simultaneously, be convenient to sum up knowhow, rationally arrange feeding volume, and be devoted to function expansion, the automation that realization is cultured and unmanned.
Summary of the invention
(frequency setting is little or equal great majority to raise the body of kinds thick at the water medium wavelength with used ripple kind with having an operating frequency, carry on the back to the thickness of fish belly as fish and to be advisable) voltage drive the microwave that is contained in certain pedestal, ultrasonic, infrared and other ripple class sensor that shakes, make them send operating wave with certain working surfaces, utilize trip to go into the blocking-up that breed kind wherein produces operating wave, reflection and Doppler effect, make sensor produce induction (or make ripple shake probe failure of oscillation), its signal is through amplifying, frequency-selecting, Doppler detects, trigger monostable flipflop thereafter after the shaping, make it open the counting gate, counter begins counting.Other is provided with multi-level clock, presets and comparison circuit, do not reach setting numerical value at clock circuit and unit interval inside counting device, the quenching pulse of clock circuit by the zero clearing gate with counter O reset, when reaching setting numerical value, this value of series comparator is closed this zero clearing gate, block of the zero clearing of this grade clock circuit, make counter enter the second clock duty counter, reciprocal in this way.When counter reached setting numerical value, output is relevant reported to the police and control signal, when reaching the setting maximum, exports this counter terminal warning and control signal and with the whole zero clearings of counter, begins next working cycles.The setting of multi-level clock and comparator just makes microprocessor have Fuzzy Processing function and correlation values adjustability like this, personnel easy to use are according to the actual floating head of culturing kind and seek the relevant number that presets of reaction time setting that the food state produces sensor, for the ease of observing, can connect relay indicating light behind each sensor, the monostable time of monostable flipflop behind each sensor can be set as required, but must not be less than the single count pulse time.Clock and counter are by the reference clock co-ordination.
In addition, but the final floating head decision signal input measurement intensity of illumination of passive type output and the microprocessor of timing computing, trigger impulse as timer and related operation, make its second day can initiatively calculate fish and shrimp initial floating head time roughly in this breeding water body at night on the same day, and initiative alarming and start aerator then.
This microprocessor is that illumination is measured and the automatic computing electrical equipment of timing automatically, by photocell, A/D converter, optically controlled delay circuit, clock circuit, memory, accumulator, divider, timer, measure and computing management circuit composition, daytime at sunrise optically controlled delay circuit with the accumulator zero clearing, (the optically controlled delay circuit working value is sunrise or acronical intensity of illumination, time-delay is that Changes in weather causes repeatedly zero clearing to accumulator in this period), measure, the computing management circuit begins to command photocell, A/D converter, accumulator carries out the interval and regularly measures, data latch, the A/D converter zero clearing, the working procedure that measurement result adds up, evening, optically controlled delay circuit stopped illumination photometry together with the computing management circuit at sunset, the work that adds up, accumulation result latchs.The floating head timer picks up counting, and accumulation result latchs divided by the latch data in the oxygen consumption memory and with the result, and the oxygenation timer that is attached thereto picks up counting, when identical with latch result, and output alarm and aerator starting-up signal.
It needs to be noted that the normal operation of oxygenation timer will be waited until the second day behind the input pulse signal.Raise the nose above water to breathe after the signal arrival, the floating head timer stops timing, and arithmetic unit is also squeezed into the oxygen consumption memory with this result with the illumination accumulated value on the same day divided by this duration.This result namely for this reason in the water body unit interval one of comprehensive oxygen demand roughly than number.(because of dissolved oxygen in the water body has more than 90% photosynthesis from organism in water, so day quantity of illumination and water body dissolved oxygen output have indirect conversion relation).The oxygen consumption storing value is the zero algorithm mistake of bringing when preventing from using for the first time, can make the same day illumination accumulated value divided by be the oxygen consumption storing value add behind the minimum numerical value and value, so namely prevented the algorithm mistake, adapted to again the aquaculture kind grow up bring oxygen demand day gradually increase problem.This adds numerical value and can artificially be provided with by latch, kills two birds with one stone.As a same reason, for avoiding the repeatedly input of internal floating head pulse on the one, (after closing automatically as aerator, fish and shrimp raise the nose above water to breathe to cause passive processor action once more) cause computing to be slipped up, the computing management circuit can be opened this gate with light-operated circuit raising the nose above water to breathe for the first time promptly to close this pulse input gate after pulse arrives again to next day.Though like this, if when meeting successive cloudy days or foggy weather, initiatively type also may operate as normal for this, and warning work at that time will rely on passive type fully.
But more than two machine on-line workings, also can sell according to the market demand extension set, by user's manual mode operation part link, as raising the nose above water to breathe the input of pulse.For the functional reliability that improves device and reduce malfunction, can install a small-sized oxygen-increasing device additional, working water face at oxygen-increasing device is established sensor, by the little aerator of machine control, time control or manual unlocking, lure into raise the nose above water to breathe fishes and shrimps to oxygen enrichment, be that the working sensor district concentrates, thereby finally open the high-power aerator in order to the oxygenation of full pond.The elementary numerical control system of putting of illumination photometry computing timer and monitoring dark Doppler's detector of raising the nose above water to breathe just is advisable with little aerator like this.
Embodiment
The key of (take the main breed variety fish of aquatic products as example) passive type type is that can sensor accurately catch fish locomotion position and state, and the accurate judgement of food and proper motion raised the nose above water to breathe, seeks by microprocessor to fish.Fish raises the nose above water to breathe to divide two stages, promptly raises the nose above water to breathe under water and water surface floating head.Raising the nose above water to breathe under water is initial period, this moment fish because of anoxic by floating to shoaling layer water than deep water.And move about in alarm, run helter-skelter, seek the oxygen enrichment pool in the underwater, be commonly called as dark floating head this moment.When anoxic is more serious, fish will be swum to the water surface and with head and be stuck up the water surface, swallow air to obtain oxygen with mouth, and this is the after-stage of raising the nose above water to breathe, i.e. bright floating head.If this kind raised the nose above water to breathe overlong time, though then start the aerator fish also with unable to aerator near and cause the casualties.According to These characteristics, the working sensor corrugated that the monitoring fish and shrimp are raised the nose above water to breathe should be arranged in the upper water.Extremely being advisable about 30 centimetres under water of monitoring fish with the water surface.(the general degree of depth of breeding water is between 50 to 250 centimetres).The upper strata sensor is based on the frequency-selecting working method, and finally is controlled to be the main frame of full pond oxygenation, and lower floor's sensor is based on Doppler's detection mode, controls little, high-power aerator more successively by multistage.Each sensor emission, reception directive property are take the covering of the fan pie-shaped as good, and available pedestal cooperates to be realized.Working condition for the ease of user's monitoring sensor.Should be connected in series a work indication light diode thereafter, the user can accurately not put the duration of clock and the numerical value of comparator in the time of flickering in the period of floating head by observing each sensor indicator lamp, reduces malfunction.For reducing power consumption and reducing cost.The sensor of same aspect can be respectively towards, the gate circuit combination is adopted in output, connects thereafter same road Fuzzy Processing circuit again, as long as there is like this a sensor to produce induction, counter can be started working, and has also increased the reliability of installing.The monostable circuit that sensor or the output of its gate circuit are connect also can be reacted equally when the sensor sensing time was less than count pulse when counter was swum across fast to fish and be caught counting.
The sensor that the monitoring fish seeks food motion should be located in the food pool, take Doppler's testing as main, and cooperates the timing circuit of feeding, and forms gate circuit and more jointly makes a response, and accomplishes regularly, quantitative feeding.
Various sensor probes all answer cloth below the water surface, and its buoyancy aid wind and wave resistance will be got well, and to reduce the stormy waves reflection sensor are produced excessive impact, causes malfunction.(photo resistance of photocell and light-operated circuit then should be placed on daylighting and well locate, and is as the criterion can accept one day solar radiation)
Should connect trigger or the timing circuit of certain monostable time after the various alarm signals of digital comparator output and the control signal, but repeated trigger, and its monostable finishes after the monostable time after last triggers.So just accomplished continuation and the randomness of aerator when raising the nose above water to breathe to take place.
The selection of each sensor should be considered its ripple specific character and cost performance, can organize to contain and use to make product obtain price advantage as far as possible.Ultrasonic sensor should adopt sealed waterproof type, the centre frequency of commercially available prod is many about 40KHZ, this moment, its underwateracoustic wavelength was about 3 centimetres, can customize the above product of 100KHZ to producer for shortening its wavelength, and require its directive property closely may become sharp-pointed fan-shaped pancake shape.Because the ultrasonic penetration power is strong, its pedestal is selected sound insulation, sound-absorbing material for use, as cellular rubber etc.Ultrasonic sensor should adopt reflective, behind the receiving sensor should and selecting frequently and Doppler's testing circuit, counting comparison circuit numerical value thereafter arranges respectively, should detect the control nickel base alloy powder spray coating mixing rectangular with Doppler, frequency selection circuit is controlled high-power aerator for well.
Infrared sensor has that cost is low, frequency modulation performance good, pedestal only needs get final product every luminescent material, the advantages such as the easy control of directive property, and have large quantities of integration probes can be for selecting on the market, it is bigger that shortcoming is that transmission range is affected by the breeding water body transparency, needs normal clean and according to pond liquid manure degree regulating action distance.The reflection of this kind probe correlation all can, easily deploy to ensure effective monitoring and control of illegal activities and in the nickel base alloy powder spray coating mixing rectangular working face, go up working lining (water surface under water 2-3 centimeters) most, the monitoring water surface is raised the nose above water to breathe.Being particularly suitable for monitoring shrimps raises the nose above water to breathe.
Microwave remote sensor uses under water as long as the latent cloth electric capacity of solution and shielding problem can obtain applications well, its advantage is the easily property controlled of the direction that not only had ultrasonic transmission range advantage and good Doppler selectively but also had a light probe, has again that pedestal is easily made simultaneously, ejected wave aspect characteristics clearly.Its pedestal is easily selected good conductor (as aluminium) manufacturing for use.Antenna should be selected the lead of tape insulation skin or simply be enclosed in the metal enclosed chamber, the guide metal of its ejected wave emission or receiving port and the package header insulation that opens layer as screen, and shell shields worn-out reliable ground.
Each foundation design is namely visited before fan-shaped central point makes housing take sensor so that the work corrugated meets the demands and is as the criterion.Utilize the direction of housing to blocking-up or shielding, the emission of absorption limit sensor or the reception of ripple.(the vertical sensing that upper and lower opening limits emission or receives, left and right sides opening limits its level and points to the angle) pedestal can be installed on the Special float, also can or simply be fixed on undersurface pond on the bank by the floating drum of aerator, with wind and wave resistance performance height, the monitoring water surface is widely suitable.
For preventing because the barriers such as the long Chi An of making of transmission range reflex to receiving sensor with operating wave, or the low coverage of crossing strong obstruction emission and receiving transducer because of the ultrasonic wave penetration power installs, and launches or accepts circuit and should establish variable potentiometer and regulate its sensitivity.The transmission of signal need to be selected suitable lead (needing special wire such as microwave) because of kind.Each circuit should be carried out shielding, avoid corresponding interference.Circuit power is selected the high-quality battery, preferably adopts civil power to connect into overvoltage with it and automatically protects charging circuit, also can reliably report to the police when guaranteeing mains failure.The bimetal leaf operating distance of the also available band heating element heater of digital Fuzzy Processing circuit behind the monostable circuit that sensor causes has the temperature relay of big adjustability for usefulness, and shortcoming is to regulate poor accuracy, malfunction height.
The water layer convection current causes total build anoxic for the running that prevents nickel base alloy powder spray coating mixing rectangular causes up and down.Can be designed to small-sized atomizing aerator, form by motor, high-pressure hydraulic pump, shower nozzle.The distribution of shower nozzle cooperates with the distribution of sensor, reaches optimum efficiency.Also can ad hoc pipeline and controlled spout to sensing probe.The fouls such as algae that flushing is adhered to are finished automatic cleaning, and the water inlet of water pump should be opened in shoaling layer, can be the circle shape and distribute, and complete machine keeps level when making start, avoids affecting probe work attached to it.
In addition, can be in the executing agency of aerator, on the blade such as the wheel disc of paddle aerator periphery and waterwheel aerator magnet is installed, on buoyancy aid, near magnet running orbit place one induction coil is installed, monostable or clock circuit with this aerator of control after the induced-current amplification that this coil produces when utilizing magnet to rotate, the shaping forms NOR gate circuit, when then unexpected stall or wheel disc came off when aerator is answered duty, this gate circuit all can trigger warning circuit thereafter.Certainly, the work phase line of aerator can be formed the gate circuit comparative pattern through the step-down shaping equally, have a power failure and the phase shortage warning, by that analogy, can utilize the warning and the work indicator current of each type, the signal code that merges aerator state-detection electric current, produces by the fuel oil unit of autostart function and automatically the time control circuit of bait throwing in machine form the multilevel logic gate circuit, utilize the output of gate to trigger corresponding executive circuit and warning circuit, and insert corresponding indicator lamp and audio signal, will realize that corresponding state is reported to the police and the orderly control of various machineries.After inserting corresponding speech chip, will realize audio alert.Link to each other with warning output and intercom or with the phone of preset number function, can realize remote alarms.At adjunction Emergency Oxygen Supply facility, as behind mains failure, starting the reserve fuel unit according to control signal, or open magnetic valve after the mechanical enhancement failure and the oxygenation agent of getting ready is in advance sprayed or flow into the similar approach such as heavy bucket under water of getting ready, stall for time and wait for that the ward takes corresponding measure, can realize like this raising people's the nurse of leaving the theatre.If output, the input signal of each sensor and processor are realized pulse or frequency coding wireless connections, then can reach a people and nurse many ponds or many places oxygenation unit, but each machine is should assist the coding that withers between the adjacent raiser by it when adopting this kind mode, avoids the phase mutual interference to cause malfunction.Microprocessor can be assembled with commercially available integrated circuit, but also large-scale integrated reduces cost.The input of various signals is established the corresponding roll line of inserting with output, is convenient to the user and selects as required and connect peripheral unit.Remote alarms can be utilized the input port with the base of preset number function or overstocked old type mobile phone (this market opportunity and feasibility is arranged) adjunction special use, only need insert and the plug special of breathing out key and connecing when the raiser goes out, and the input preset number gets final product.
In addition, a kind of sound, light-operated mode are cheaply arranged, promptly adopt monostable or the clock circuit control shot-light interval pulsed exposure water surface, the sound that causes when utilizing frivolous fish dive promotes sonic sensor, the signal triggering monostable executive circuit that utilizes its to produce opens and closes aerator, severe is raised the nose above water to breathe invalid but shortcoming is its light stimulus, makes the selection of irradiation time be difficult to grasp, and easily make fish produce fatigability, but this machine can be towards the few customer group of fund.
The realization of said method and flow process can be with reference to accompanying drawings.
