The CN200810162176.1 patent proposes " based on the automatic fry counting system of computer vision ", comprise a sets of data harvester and a method of counting, said data collector is to place the water tank [4] of fry by one, two digital cameras [2,7] mutual alignment with quadrature is installed in the fry image digitization camera system that constitutes on the water tank, one computing machine [9] constitutes with the signal connection device that is connected computing machine and digital shooting system [10], said computing method are the computer programs that are stored in the computer register, its analytic process is the gradation data with the background pictures of no fry, the gradation data of the fry photo of known fry quantity obtains the relational expression between fry photo gradation data and the fry quantity, obtains to wait to count the quantity of fry by this relational expression at last.

The CN88100193.7 patent proposes " Weighing type fish (shrimp) seedling method of counting and equipment thereof ", utilize micro computer to combine with dynamically weighting power technology, can continuous monitoring fishes and shrimps seedling and the mixture weight of water change, be certain certain value thereby control the water percentage of fishes and shrimps seedling meter when heavy effectively.So not only improved the counting accuracy, and the unnecessary too much dehydration of fishes and shrimps seedling, thereby guarantee survival rate of young and improved counting rate.State on the implementation in the equipment of method, adopt gravity sensor, amplifier and digital circuit and micro computer to combine, the seed water cut when utilizing micro computer to control check weighing can also be with being for data processing.

The CN85105265 patent proposes " water fish seedling photoelectric fast counting ", to solve fry (beggar) band water method of counting. with the water fish seedling introduce in the cavity hybrid density evenly after, connect by ten several or dozens of photoelectric detectors, showing or print result after number adds up counting out. its popular style can be only with a detecting device, to detect number multiply by passage and draws institute and count sum. and this method counting is rapid, continuous, fry does not need dried up, the survival rate height, and operating process is easy.

The CN88203921.0 patent proposes " fig counter ", comprises that photoelectricity is surveyed to show and fry sliver separator part that photoelectricity is surveyed and shown that part is made of the photoelectric tube sum counter, and the fry sliver separator is made of fish gathering tube, major-minor pipe, vent pipe.Fry flows into the major-minor pipeline by the hole in the collection seedling tube, because the major-minor length of tube do not wait, fry is entered vent pipe after separately one by one, in the both sides of pipe photoelectric tube is housed, fry by after provide a pulse, and on counter, demonstrate numeral.This counter precision height (error is 3%), damage ratio little (5%), measures range 0-3 ten thousand tails/time, simple in structure, cheap, easy to manufacture, general township and village enterprises all can produce.

(3) summary of the invention

The objective of the invention is: provide simple in structure, with low cost, easily-learned easily mastered, easy to operate, be fit to China's national situation and can allow the method for counting among fish (shrimp) Miao Zaishui.

The technical solution adopted in the present invention is: examination in hospital patient red blood cell is performed such: puncture patient's finger, draw blood, dilution in proportion, be coated on the glass sheet, glass sheet is by tangent several lattices of forming of some lines anyhow, as long as count at the red blood cell of observing in the grid on the microscope, multiply by number of squares then, promptly known erythrocytic number.

We do not imitate the principle with reference to erythrocytic counting, carry out the counting of fish (shrimp) seedling.Fish (shrimp) seedling can be put into the grid that some lines are anyhow formed equally, take out one, two grid and count, multiply by total number of squares then, promptly know the quantity of total fish (shrimp) seedling.

Fig. 4 is an openning to openning to after inserting, and makes the sash (vertical view) of the solid of a similar go dish.

(5) embodiment

One, the making of counting assembly

1. cubic basin: square; Water-tight; 20～80 centimetres of the length of sides; High 10～30 centimetres, its material can be plastic plate (or sheet metal or plank) (with reference to figure one).

2. sash: process with sheet material, its sheet material can be plastic plate (or sheet metal or plank).Length is the interior length of side of cubic basin, and height is the height of cubic basin, and thickness is any, is as the criterion to be difficult for fractureing.Make some.Sheet material is slit into several opennings in proportion, and the degree of depth of openning is half of plank width, can three to ten opennings (with reference to figure two).After the making, with a plank upset, openning inserts another plank to openning; Insert like this one by one, make the sash (with reference to figure three) of the solid of a similar go dish.

Two, fish (shrimp) seedling counting

1. earlier pour fish (shrimp) seedling into the basin mouth together with water, after sash is carefully put into cubic basin.

2. sampling is counted: at random the fry of two lattices is pulled out, be placed in respectively in two little bowls, count.During sampling, preferably take out a lattice of central authorities and the lattice of a ragged edge, in the hope of accurately.

3. behind the fry numeration, fry counting with two lattices, get its mean value, multiply by total number of squares again, promptly draw the fry number.

Example: a lattice fry number is 100 tails, another lattice 108 tails, and total number of squares: 25 lattice, total fry number:

(100+108) ÷ 2 * 25=2600 (tail)

Three, the adjustment of data

If the difference of the fry number of two grids is greater than 5% of mean value, the fry of the grid in the middle of should getting is again counted, and getting above two lattice then is the most approaching these lattice of newly getting the fry number of these lattice, and another diagrid removes, and two lattice calculate total fish number.

Example: a lattice fry 100 tails, another 108 tail, so:

(108-100)÷[(100+108)÷2]＝7.69％

Its value through getting lattice again, is 105 tails greater than 5%.Compare with above two lattice, its numerical value removes that diagrid of 100 tails near 108 tails, and 105 tails and 108 tails, two lattice recomputate: (105+108) ÷ 2 * 25=2663 (tail)
