It is too simple and crude that existing fry numeration, fry counting method and apparatus has, and accuracy is low, have than complex and expensive, speed is low, uses not make, what have is unsuitable for fry, especially shrimp seedling.Do not met commercial fish (shrimp) fish (Shrimp) fry counter.
Disclose a kind of electronic counting the clear 60-31023 of Japan Patent TOHKEMY number and claimed, it comprises the container that converts weight converter, control system, display, the power supply of electric weight to and hold measured object.The course of work that this counting claims is to obtain the average weight of single measured object earlier, uses the gross weight of average weight divided by measured object then, thereby realizes counting.
The purpose of this invention is to provide a kind of fish of adopting electronic counting to claim principle (shrimp) fish (Shrimp) fry counter.Its main feature is to weigh that fry (be equally applicable to the shrimp seedling, down with) only needs the short time dehydration before the counting, and the counting macrura reevesii seedling of weighing does not dewater, so that improve the survival rate of fry; Fry to sampling is demarcated or proofreaies and correct, and makes the average weight of every fry, and the weight by mensuration fry to be counted also promptly gets the bar number of fry divided by above-mentioned average weight.
This device comprises weight/quantity converter.Control survey system, display, power supply and hold container of measured object etc., said converter belongs to the converter that weight (pressure) is transformed to electric weight, for example use pressure sensor, generally can adopt weight to be converted to electric oscillation frequency (pulsed quantity) fry.
The control survey system comprises microcomputer or single board computer, interface circuit and function key etc., for example adopts the Z-80 single board computer.Function key can be established zero clearing, the button end, demarcation or correction, measures or be added up etc." zero clearing " and " at the bottom of the button " is the warming-up exercise before the measurement count, and wherein " at the bottom of the button " key is will the weight input measurement system storage of the measurer of water be housed, and removes the influence of the title fish container of dress water to counting, simplifies counting process.
Converter generally can be selected suitable electronic scale for use.Display can adopt light emitting diode (LED) numeral to show.Power supply can adopt ac-dc dual power supply.
The fry dehydration can have a strong impact on its survival rate, for this reason, the container that holds measured object that this device is set comprises and claims the fish container and leak to contain the fish container, the time claim to be with water in the fish container when carrying out the fry counting of weighing, put into and claim the fish container counting of weighing putting into the fry of containing short time dehydration in the fish container of leaking.
The course of work of this device is to measure the title fish container of containing water earlier and leak to contain the weight W of fish container
10, and its data are stored, finish button end step.Get N bar fry and put into to leak to contain in the fish container and put into the title fish container of containing water after the short time dehydration, operate demarcation or the check key of corresponding number N, deducting weight W
10Promptly get later the weight W of N bar fry
N, then can try to achieve the average weight W of every fry
N=W
N/ N, and deposit these data in memory cell, demarcate or proofread and correct promptly to accuse and finish.Go the fry of demarcating, measure the title fish container of containing water once more and leak and contain the weight W of fish container
1, as mentioned above, fry to be measured to be put into to leak put into the title fish container of containing water after containing the dehydration of fish container, operational measure or accumulation key then can obtain the weight W of fry
RDivided by W
NN as a result
1, this is the bar number of fry to be measured, and shows the result by display.
If fry quantity is bigger, be subjected to the relevant sensitivity of converter with measuring system, the restriction of the linearity and conversion range etc. then can take multiple measurements and adds up one by one; Also can adopt artificial zero clearing, again Ji Shuo method.
Demarcate or corrected value can be provided with several, N=200 for example, 400,800 ... to adapt to the fry and the accuracy requirement of different sizes.
The present invention had both utilized to count one by one sampling calibration value N had accurately been counted, the applied statistics regularity of distribution again, and the growth rhythm according to fish, shrimp seedling can obtain count results preferably.
Calibration value is obtained big more, and the sensitivity of converter is high more, and the range of linearity is wide more, and then Ji Shuo accuracy is just high more.In the counting process, only before counting fry is carried out the short time dehydration, do not dewater during counting, not damaged by other, survival rate is higher.Be not only applicable to fry, be applicable to the shrimp seedling yet, be particularly useful for fish, shrimp seedling plant, fish, shrimp species class are not limit.This device adopts pressure sensor especially directly is converted to the electric oscillation frequency with weight, utilizes microcomputer or single board computer to control and measure and digital displaying result, that counts is highly sensitive, and the speed height is easy to use, only need once calibration, count number can be any.
