Description

A device for accurate detection, counting and grading of fishery organisms

technical field

The invention belongs to the field of fishery engineering equipment and technology, and relates to equipment for the number statistics of fishery organisms and the non-destructive automatic and accurate detection of body length and size, and realizes the automatic population division of fishery organisms according to the results of body length and size detection, thereby It is very convenient to count the population of fishery organisms, select and distinguish fishery organisms of different sizes, and improve the efficiency and convenience of the fishery production process.

Background technique

In the process of fishery production, the statistics and size detection of biomass often run through the whole process. Whether it is the hatching and cultivation of seedlings, sales and transportation, or the growth of larvae and the catch and sale of adults, all of them involve fishery biomass. Statistics and size detection needs. However, there has never been any easy and convenient way to carry out the statistics and size detection of fishery biomass. Usually, the statistics and size detection of fishery biomass are carried out separately, or sampling surveys are used to obtain approximate data and information. Sampling survey is the most common means of detection and analysis of fishery organisms, but it is time-consuming and laborious, and often causes certain damage to fishery organisms. In recent years, with the development and progress of scientific and technological means, there are more and more techniques for fishery biometrics and grade distinction. In general, in addition to sampling surveys, counting methods for fishery organisms include resistance counting, optical counting, acoustic counting, and computer vision counting, each of which has different advantages and disadvantages. Among them, the image intelligent recognition technology represented by computer vision counting is one of the hot spots of development, and it can simultaneously carry out the statistics and analysis of the size of fishery organisms. with a considerable error. The technology for fishery biological classification generally adopts the technology of mechanical sieving, and the effect is good. There are many related patent technologies, such as application numbers 200410036135X, 2004100623600, 2010202918439, 2012104756841, 2012104756856, 2012104757420, 201320491572, etc. Most of the grading techniques for fishery organisms are mechanical grading techniques, and do not involve the statistics of the number of fishery organisms and the precise measurement of their size. The mechanical screening method will also cause certain damage to fishery organisms.

When the fishery organisms are forced to pass one by one, it is very convenient to realize the statistics and detection of the number of fishery organisms one by one. Most of the current fishery biological counting technologies are based on such schemes, usually using photoelectric technology as the main detection method, including According to the statistics of its quantity and weight, there are many related patented technologies. For example, the application numbers are 851052657, 871024101, 882028367, 882039210, 2008101621761, 2010105426549, 2013203099202, 2013204827264 and other patented technologies, as well as some publicly reported literature, all involving various photoelectric detection, computer vision detection, batch detection, etc. Counting method of fishery organisms such as fry. However, among the various techniques and methods of fishery biometrics and grading, there is no technology that combines the process of fishery biological size detection, quantity statistics, and size grading. The related processes are usually carried out separately, which is not very convenient and fast. . The patent of the present invention combines the above-mentioned processes through a unique design to quickly realize the statistics of fishery biological populations, size detection, and classification of specifications and grades at one time, which is beneficial to fishery production.

Contents of the invention

The purpose of the present invention is to solve the defects and insufficiencies of the current existing technologies, fill the technical gaps in fishery biological quantity statistics, specification detection and grading, and establish a systematic solution for fishery biological specification detection, quantity statistics, and grading. The rapid detection and classification of fishery biological groups can be realized. The detailed technical plan is as follows:

The fishery biological accurate detection calculation and grading device designed by the present invention mainly includes four major components of fishery biological input system, detection system, grading system and control system. How and how it works.

The fishery biological input system consists of a stable water flow input faucet, a fishery biological input container, a lining screen, an adjustable inner lining gasket, a fifth electric valve, and a sixth photoelectric detector. The organisms in the direction of the long axis of the body pass through the input system one by one, and then enter the detection system part. When the fishery organisms pass through the No. 5 electric valve one by one, the stable water flow input faucet maintains a certain flow of water flow, preventing the water level in the fishery organisms input container from being too low due to the leakage of the liner screen, while maintaining The water flow in the whole system is smooth and continuous. Assume that the average body length, body height, and body thickness of the graded fishery species to be detected are d1, d2, and d3, respectively, and generally d1>d2>d3. Then, the mesh aperture size of the lining screen should be much smaller than d2, that is, it is impossible for the fishery organisms to be detected to leak through the lining screen. The diameter-adjustable lining gasket is a plastic elastic gasket that maintains a circular shape, and its diameter can be adjusted arbitrarily within the inner diameter of the detection pipe.

In order to ensure that it is impossible for multiple fishery organisms to be detected to pass through or jam at the same time, the diameter of the diameter-adjustable inner liner gasket should be adjusted between 1.3-1.6 times d2, that is, only one fishery organism to be detected can be allowed at a time. Its body passes in the direction of the long axis, and cannot pass horizontally, nor can more than 2 fishery creatures pass at the same time. When the system starts to work, the stable water flow input faucet starts to input a certain flow of water flow to maintain a certain water level in the fishery biological input container and maintain the smooth and continuous water flow in the entire system. At this time, the fishery biological input container can be input. Detected fishery organisms. Select the appropriate detection and counting mode, when the system starts counting, the fifth electric valve is opened first, allowing a fishery organism to be detected to pass through. Then, the opening and closing of the fifth electric valve is controlled by the central controller. When the fishery organisms pass through the No. 6 photoelectric detector completely, and the blocking of its light ends, the No. 6 photoelectric detector sends a working signal to the central controller, and the central controller sends a closing job to the No. 5 electric valve. Signal, order the electric valve No. 5 to be closed, to ensure that there is only one fishery creature in the detection system before the fishery creature entering the detection system is detected and graded. When the fishery biological detection is completed, one of the eleventh, fourteenth, and seventeenth photoelectric detectors will send a signal to the central controller that the detection is complete, and then the central controller will send a signal to the fifth electric valve. Send out an open control command signal, order the fifth electric valve to open and put in the next fishery organism, and enter the next counting and detection process. Based on the above working principles, the distance between No. 6 photoelectric detector and No. 5 electric valve should be as small as possible, much smaller than the average body length d1 of fishery organisms, so as to ensure that No. 6 photoelectric detector feeds back signals to the central controller And order the No. 5 electric valve to close as short as possible. Before the No. 5 electric valve is controlled to close, no second fishery creature will appear in the detection system. That is to say, after the No. 6 photoelectric detector detects that the No. 5 electric valve puts in a fishery creature, it immediately informs the central controller to close the No. 5 electric valve, and the fifth electric valve is opened again by the classification system. The feedback signal is used for control, or the central controller is used for control in the pause working mode.

Subsequently, the fishery organisms enter the detection system of the device of the present invention. The detection system is composed of the seventh photoelectric detector, the detection pipeline, the ninth photoelectric detector, and the central controller. Its function is to accurately measure the size of the fishery organisms. It is its body length, and its value is an unknown number D centimeters. The weight of fishery organisms can be converted from their body length according to empirical formulas. The detection pipe is made of transparent materials, such as glass or organic glass and other transparent materials. All positions where photoelectric detectors are installed in the detection pipeline are planar structures to ensure the effective passage and detection of light detected by photoelectric detectors. The other positions of the detection pipeline are cylindrical structures, and the curved corners maintain an appropriate radian to ensure the smooth passage of fishery organisms without injury. The specific detection and calculation process of fishery organism length is described in detail below.

The motion process of the detected fishery organisms in the transparent detection pipeline is subject to the combined effects of various forces such as gravity, buoyancy, and friction, and can be approximately regarded as a uniformly accelerated linear motion. According to the process analysis in Fig. 2 in the accompanying drawings of the description, when the head and tail of fishery organisms respectively pass through No. 7 photoelectric detector and No. detected by the photodetector. Assume that the moving speeds of fishery organisms at t1, t2, t3, and t4 are respectively v1, v2, v3, and v4, the acceleration of fishery organisms is a, and the distance between the seventh and ninth photoelectric detectors is known as L cm , the body length of the fishery organism is unknown D cm. It takes T1, T2, T3, and T4 milliseconds for fishery organisms to move from time t1 to time t2, from time t2 to time t3, from time t1 to time t3, and from time t1 to time t4, namely: T1=t2-t1 , T2=t3-t2, T3=t3-t1, T4=t4-t1. According to the above conditions, the following relationship can be obtained from the uniformly accelerated linear motion equation:

L=v1×T3+0.5×a×T3 ²

L+D＝v1×T4+0.5×a×T4 ²

LD=v2×T2+0.5×a×T2 ²

v2=v1+a×T1

D=v1×T1+0.5×a×T1 ²

In the above algebraic equations, the unknowns include v1, v2, a, D, and the others are all measurable known data, which are closed algebraic equations. Based on this, the exact length D of fishery organisms can be solved, and its value is as follows:

D＝L×(T1/T3)×[(T2 ² +T4 ² +T1T2+2T1T3-2T3 ² -T1T4)/(T2 ² +T4 ² +2T1T2-T2T3-T3T4)]

The above-mentioned fishery organism length detection data and solution process are compiled as a fixed program, which is embedded in the central controller. When fishery organisms pass through No. 7 and No. 9 photoelectric detectors one by one, the accurate The body length is D, and there is no direct contact with fishery organisms, without any additional harm.

The classification system is composed of at least three fishery biological collection subsystems, control valve subsystems and a central controller. Each fishery biology collection subsystem includes a fishery biology collection box, a photodetector, and an electric valve. The number of fishery organisms in compliance with the regulations, and feedback signals to the central controller. The electric valves in each fishery biological collection subsystem and the electric valves in the main pipeline form the control valve subsystem in the classification system, including the tenth electric valve, the twelfth electric valve, the fifteenth electric valve, Electric valve No. 21. The aforementioned computer valves are commanded and controlled by the central controller, and their opening and closing actions in different combinations can transport the fishery organisms that meet a certain regulation to the designated fishery organisms collection box. The grading system can transport fishery organisms to suitable fishery organism collection boxes according to the length of fishery organisms measured by the detection system, and according to the feedback from No. 11, No. 14, and No. 17 photoelectric detectors The information counts the number of fishery organisms of different sizes. If it is necessary to classify and screen the detected fishery organisms, select the detection and classification mode in the central controller, and input the limit value of the length and size of the fishery organisms to be screened in advance. For example, it is necessary to divide the population of fishery organisms to be tested into three groups of large, medium and small, and set the body length limits as ≧d _large , d _large ﹥ and ≧d _small , ﹤d _small , and enter the body length limit into the central controller, and set corresponding fishery biological collection boxes, for example, set large, medium and small size fishery biological collection boxes corresponding to No. 1 fishery biological collection box, No. 2 fishery biological collection box, and No. 3 fishery biological collection box. The working process of the grading system is briefly described as follows.

When the detection system detects that the length D≧d of the currently detected fishery organism is _large , the central controller judges that it should be divided into large-scale populations, and the control system sends the following control command signals, the tenth electric valve is closed, the twelfth No. 1 electric valve is opened, and No. 15 and No. 21 electric valves remain in the original state, so the currently detected large-scale fishery organisms will be transported to the No. 1 fishery organism collection box, that is, the large-scale In the fishery creature collection box. After the eleventh photoelectric detector detects the passage of fishery organisms, it feeds back to the central controller to order the fifth electric valve to open and put in the next fishery organism for detection and classification. Before the body length of the next fishery organism is measured and the size of the classification is judged, each valve of the grading system remains in the last working state to maintain the smooth flow and normal operation of the system.

When the detection system detects that the length d of the currently detected fishery organisms is _{larger than} D≧d, the central controller judges that it should be divided into medium _- sized populations, and the control system sends the following control command signals, No. 10, No. 15 The electric valve No. 12 and No. 21 are closed, so the currently detected medium-sized fishery organisms will be transported to the No. 2 fishery organisms collection box, which is the medium-sized fishery organisms collection box . After the No. 14 photoelectric detector detects the passage of fishery organisms, it feeds back to the central controller, commands the fifth electric valve to open, and puts in the next fishery organism for detection and classification. Before the body length of the next fishery organism is measured and the size of the classification is judged, each valve of the grading system remains in the last working state to maintain the smooth flow and normal operation of the system.

When the detection system detects that the length of the currently detected fishery organism is D<d _hours , the central controller 30 judges that it should be divided into small-scale populations, and the control system sends the following control command signals, No. 10 and No. 21 When the electric valve is opened and the No. 12 and No. 15 electric valves are closed, the currently detected small-scale fishery organisms will be transported to the No. 3 fishery organism collection box, which is the small-scale fishery organism collection box. After the No. 17 photoelectric detector detects the passage of fishery organisms, it feeds back to the central controller, commands the fifth electric valve to open, and puts in the next fishery organism for detection and classification. Before the body length of the next fishery organism is measured and the size of the classification is judged, each valve of the grading system remains in the last working state to maintain the smooth flow and normal operation of the system.

Each fishery biological collection box is equipped with an overflow mesh, its function is to let the excess water flow overflow the fishery biological collection box, to avoid the accumulation of fishery organisms and excessive flow during the working process of the system, causing fishery organisms to escape from the fishery biological collection box. When the density of fishery organisms in a certain fishery biology collection box is too large, it is possible to touch the pause working mode button in the central controller when it is possible to cause fishery biology damage due to the crowding effect. That is to say, after the grading system completes the grading work of a fishery organism, the central controller will no longer order the No. 5 electric valve to open, suspend the input of fishery organisms, store all data information temporarily, and suspend counting, detection, and grading work for a few seconds. Allow enough time to replace a full Fishing Biobin with an empty Fishing Biobin. The replacement work can be carried out by replacing the operating handle of the fishery biological collection box, which is simple and quick. After the replacement of the fishery biological collection box is completed, touch the button on the central controller again to cancel the system's pause mode. The central controller orders the fifth electric valve to open again, put in a fishery creature, and continue to start the fishery creature counting, Inspection and classification work.

If it is necessary to sieve the screened population of fishery organisms into more groups according to the length of fishery organisms, the screening function of the grading system can be expanded, and more control electric valves, photoelectric detectors and fishery organisms can be added. collection box. For example, 4, or more than 4, can be set in the controller according to the length of fishery organisms, and the limited range is graded; Fishery biological screening becomes 4 kinds, or more than 4 kinds of populations with different sizes. That is to say, the system of the device, especially the central controller system, has reserved function modules for function expansion. If in some cases, the detection and classification function of the single channel of the device system cannot meet the production needs, and it takes a long time, then a plurality of device systems of the present invention can be used in parallel, that is, multiple devices of the present invention can be used. The precise detection and counting of fishery organisms is connected in parallel with the grading device, which can be turned on and used at the same time to achieve the function of simultaneous detection and screening of multiple channels and improve work efficiency.

When it is necessary to divide the fishery biological population into more than three grades, the device of the present invention can also be used to carry out repeated classification. That is, first apply the device of the present invention to roughly classify fishery organisms; then, for each fishery organism population that has been roughly divided, apply the device of the present invention again to carry out the next more detailed classification work; repeat the above two steps In this step, the original fishery biological population can be divided into any required degree of detail to meet the needs of different fishery production.

The control system of the present invention is composed of a central controller, signal input channels of each photoelectric detector, and control command channels of each electric valve, as shown in Figure 1 in the accompanying drawings. The function of the control system is to adjust and control the coordination of the fishery organism input system, detection system, and grading system, to ensure that only one fishery organism is put into the fishery organism input system at a time, to accurately calculate and analyze the input data of the detection system and to obtain the fishery organism body size. Long, judging the size division of fishery organisms, controlling the transfer of fishery organisms to the fishery organism collection box of corresponding specifications, after the judgment system completes the detection and classification of one fishery organism, it starts to put in the next fishery organism, and starts the next round. Inspection and classification work. When the counting, detection, and grading work is completed, touch the work completion button, and the central controller will analyze and count all the data information of counting, detection, and grading fishery organisms, generate a work report, and report the total number of fishery organisms counted and their average volume. Length and mean square deviation range, detailed data such as the respective quantity, average body length and mean square deviation range of large, medium and small fishery organisms.

In order to ensure the better realization of the above-mentioned technologies, the present invention provides a method for manufacturing a device for accurately detecting, counting and grading fishery organisms. The specific steps are as follows:

①Design the main body and molds of each component of the precise detection, counting and grading device for fishery organisms;

②Making and molding the molds of each part designed in the process of ① or processing and molding by other methods;

③Assemble the parts processed and formed in the process of ②.

In the device of the present invention, in each round of detection and classification work, the detection system and the classification system are always only for the same fishery organism, so as to ensure the accuracy and reliability of the detection and classification work. After each round of detection and classification is completed, the control system starts to order the fishery organism input system to input the next fishery organism, and repeat the next round of detection and classification. All working processes are automatically controlled by electronic programs, which are fast, concise and accurate, and the detection and grading work process is smooth. During the detection process, there is no direct contact with the fishery organisms to be detected, and basically no additional damage is caused to fishery organisms. Therefore, the device of the present invention can be easily applied to the counting, size detection, and specification population division of various types of fishery organisms. It has various functions, a wide range of uses, simplicity and convenience, and high efficiency. links, save manpower and material resources, and improve the efficiency and effectiveness of fishery production.

Detailed ways

The specific implementation manner of the present invention will be described in detail below in combination with the technical scheme of the present invention and the accompanying drawings.

The patent of the present invention is composed of four parts: fishery biological input system, detection system, classification system and control system. The detailed components include stable water flow input faucet 1, fishery biological input container 2, lining screen 3, and inner lining with adjustable diameter Gasket 4, No. 5 electric valve 5, No. 6 photoelectric detector 6, No. 7 photoelectric detector 7, detection pipeline 8, No. 9 photoelectric detector 9, No. 10 electric valve 10, No. 11 photoelectric detector Detector 11, No. 12 electric valve 12, No. 1 fishery biological collection box 13, No. 14 photoelectric detector 14, No. 15 electric valve 15, No. 2 fishery biocollector 16, and No. 17 No. photoelectric detector 17, No. 3 fishery biological collection box 18, No. 21 electric valve 21, central controller 30.

Stable water flow input faucet 1, fishery biological input container 2, lining screen 3, diameter adjustable inner lining gasket 4, fifth electric valve 5, sixth photoelectric detector 6 and central controller 30 form the fishery biological input system, whose role is to ensure that fishery organisms enter the system tail by tail. When the system starts to operate, the fifth electric valve 5 is opened for the first time and the first tail of fishery organisms to be detected and graded is put in, and when the sixth photoelectric detector 6 detects that the fishery organisms have completely entered, a feedback signal is sent to the central controller 30, Order the fifth electric valve 5 to close. Then, the opening of the fifth electric valve is controlled by the signal fed back by the grading system. After the grading system completes the detection and grading of a fishery organism, the eleventh photoelectric detector 11, the fourteenth photoelectric detector 14, One of No. 17 photoelectric detectors 17 feeds back a signal to the central controller 30, notifying the central controller 30 to order the fifth electric valve to open and put in the next fishery organism. But, under the suspending mode of work, when the suspension of the system is removed and the system starts working again, the same as the initial start-up work of the system, the central controller 30 first orders the fifth electric valve 5 to open and put in a fishery creature, and continue to start counting , testing, and grading work.

No. 7 photodetector 7, detection pipeline 8, No. 9 photodetector 9 and central controller 30 jointly form a detection system, and a fishery creature passes through No. 7 photodetector 7 and No. 9 photodetector end to end. 9, and the distance between No. 7 and No. 9 photodetectors, the precise body length of the passing fishery organisms can be calculated. Relevant calculation formulas and calculation programs are embedded in the central controller 30. When a fishery creature passes through No. 7 and No. 9 photodetectors successively, the central controller 30 can immediately calculate the body length of the fishery creature.

The grading system is composed of three fishery organism collection subsystems, or more fishery organism collection subsystems, a control valve subsystem and a central controller 30 . Each fishery biology collection subsystem includes a fishery biology collection box, a photodetector, and an electric valve. The quantity of fishery organisms conforming to the regulation is fed back to the central controller 30 . The electric valves in each fishery biological collection subsystem and the electric valves in the main pipeline form the control valve subsystem in the classification system, including the tenth electric valve 10, the twelfth electric valve 12, the fifteenth electric valve Valve 15, No. 21 electric valve 21. The foregoing computerized valves are commanded and controlled by the central controller 30, and their opening and closing actions in different combinations can transport fishery organisms meeting certain regulations to designated fishery organism collection boxes. Input the body length limit value of the population size of the fishery organisms to be divided into the central controller 30 in advance, and specify the fishery organisms collection boxes of the populations with corresponding specifications. After the central controller 30 calculates the precise body length of the fishery organisms based on the information data provided by the detection system, it then judges which type of fishery organisms the current fishery organisms should belong to Populations, such as fishery creatures belonging to large, medium, and small sizes, and then order the electric valves No. 10, No. 12, No. 15, and No. 21 to open or close accordingly, Transport the detected fishery organisms to the fishery organisms collection box of corresponding specifications to complete the grading action of fishery organisms. When one of No. 11, No. 14, and No. 17 photoelectric detectors detects the input of fishery organisms, it will notify the central controller 30 that the grading work of the current fishery organisms has been completed, and the fifth photoelectric detector can be ordered. The electric valve 5 is opened, and the next fishery organism is put in to start the next round of fishery organism detection and classification.

After all fishery organisms to be detected are detected, counted and graded, the work completion button on the central controller 30 is touched. The central controller 30 starts to analyze and count all the information data of detection, counting and grading, generate a work report, and report the total quantity of the counted fishery organisms and their average body length, mean square error range, and the respective quantities of large, medium and small fishery organisms , average body length, mean square error range and other detailed data.

Based on the foregoing workflow and technical analysis, the device of the present invention can complete the counting, measuring and grading work of different types of fishery organisms, and the central controller 30 can select counting mode, measuring mode, grading mode, mixed mode and pause mode, and proceed one by one below elaborate.

In the counting mode, the user only plans to know the quantity information of the fishery biological population and does not care about other information, so he can choose the counting mode, and the system only completes the statistical work of the fishery organisms, and does not perform further detection and classification work. In this working mode, the system selects the fifth electric valve 5 to always be open, and the first fishery biological collection box 13 is the current working fishery biological collection box by default, the twelfth electric valve 12 is open and the tenth , No. 15, and No. 21 electric valves are in the closed state, then the fishery organisms to be detected pass through the fishery organism input system and the detection system one after another continuously, and finally enter the No. 1 fishery organism collection box 13, and the central control The device 30 accumulates the quantity information of fishery organisms according to the signal fed back by No. 6 photoelectric detector 6, and the information fed back by No. 7, No. 9 and No. 11 photoelectric detectors can be used as a reference for comparison and correction data when counting quantities. use. Under this mode of work, also can set the No. 2 fishery biological collector 16 in the central controller 30, or No. 3 fishery biological collection box 18 is the target fishery biological collection box of counting work, corresponding electric valve action is, No. 10 and No. 15 electric valves are opened and No. 12 and No. 21 electric valves are closed, or No. 10 and No. 21 electric valves are opened and No. 12 and No. 15 electric valves are opened. The valve is closed. When the number of fishery organisms in the target fishery biological collection box is large enough, in order to avoid the crowding and injury of fishery organisms, you can use the pause work mode to suspend the counting work of the system and allow enough time to replace the fully loaded fishery biological collection box. After replacing the new blank fishery biological collection box, you can touch the button in the central controller 30 to remove the pause mode and continue the counting work of fishery organisms. After the counting work is completed, the central controller 30 generates a work report to report the number of fishery species counted. The counting mode is suitable for the situation where only the number of fishery organisms needs to be known. The system works continuously, and the electric valves do not perform frequent opening and closing actions. The work efficiency is high and time is saved. It is recommended that fishery organism length detection and monitoring are not required. When classifying work, the counting work mode should be selected first.

In the detection mode, the user intends to know the number of fishery organisms to be detected, the average body length, the range of mean square error and other data information, but does not need to divide the populations of different sizes of fishery organisms, so the detection work mode can be selected. In this working mode, the system selects the fifth electric valve 5 to always be open, and the first fishery biological collection box 13 is the current working fishery biological collection box by default, the twelfth electric valve 12 is open and the tenth , No. 15, and No. 21 electric valves are in the closed state, then the fishery organisms to be detected will pass through the fishery biology input system and the detection system one by one continuously, and enter the No. 1 fishery biology collection box 13, and the central controller 30 According to the signal fed back by No. 6 photoelectric detector 6, the quantity information of fishery organisms is accumulated tail by tail, and the body length information of each fishery organism is calculated according to the time signal fed back by No. 7 and No. The information of the photodetector can be used as a reference for comparison and correction data when counting quantities. Under this mode of operation, also can set the No. 2 fishery biological collector 16 in the central controller 30, or No. 3 fishery biological collection box 18 is the target fishery biological collection box of detection work, corresponding electric valve action is, No. 10 and No. 15 electric valves are opened and No. 12 and No. 21 electric valves are closed, or No. 10 and No. 21 electric valves are opened and No. 12 and No. 15 electric valves are opened. The valve is closed. When the number of fishery organisms in the target fishery organism collection box is large enough, in order to avoid the crowding and injury of fishery organisms, you can use the pause mode to suspend the detection work of the system and allow enough time to replace the fully loaded fishery organism collection box. After replacing the new blank fishery organism collection box, the button in the central controller 30 can be touched to remove the pause mode and continue the detection work of fishery organisms. After the detection work is completed, the central controller 30 generates a work report, reporting information and data such as the quantity, average body length, and mean square error range of the detected fishery population. The detection working mode is suitable for the situation where the number of fishery biological populations and the overall size need to be known. The system works continuously, and the electric valves do not perform frequent opening and closing actions. The work efficiency is relatively high and it saves time. It is recommended that no fishery biological When working in size classification, the detection work mode should be selected first.

In the grading mode, users can pre-set the body length limit values of fishery organisms of different specifications according to the requirements of different body length ranges, and carry out the screening work of fishery organism populations. In this mode, the user can program and set the simple operation mode in the central controller 30, select the grading work mode, and input different body length requirements and limit values according to their own different needs, and specify the corresponding body length fishery The location of the fishery biological collection box for the biological output, and the data information requirements for the final generation of the report, etc. For example, _the population of fishery organisms to be tested needs to be divided into three groups: _large , _medium and _small . The fishery biology collection boxes are No. 1 fishery biology collection box 13 , No. 2 fishery biology collection box 16 , and No. 3 fishery biology collection box 18 . Its working process is that the input system controls the fifth electric valve 5 to input fishery organisms tail by tail, the detection system accurately detects the length of fishery organisms, and the central controller 30 judges the size of the detected fishery organisms to determine whether they belong to Which type of fishery organisms, and order the grading system to transport them to the corresponding fishery biology collection boxes. For the specific judgment and grading process, please refer to the relevant part of the content of the invention, and then carry out the next round of fishery biology detection and Grading work. In the grading mode, at each moment, there is at most one fishery creature in the system, and the detection, judgment and grading and screening of this fishery creature are completed in sequence, and then the next fishery creature is input to start the next round The inspection and grading of fishery organisms are carried out accurately to ensure the accurate screening of fishery organisms. When the number of fishery organisms in a certain fishery biological collection box is large enough, in order to avoid the crowding and injury of fishery organisms, you can use the pause mode to suspend the detection and grading work of the system, and allow enough time to replace the fully loaded fishery biological collection box. After replacing the new blank fishery organism collection box, the button in the central controller 30 can be touched to remove the pause mode and continue the detection and classification of fishery organisms. After the grading work is completed, the central controller 30 generates a work report, reporting information and data such as the overall detected fishery population and the fishery biomass, average body length, and mean square error range of large, medium, and small populations of different sizes. Distinguishing and screening different sizes of fishery biological populations is the most common requirement in the fishery production process. The grading work mode can be applied to such occasions, and it is also one of the most superior design aspects of the present invention.

In the mixed mode, it is applied to various situations in which the user has other special needs in addition to the above-mentioned situations. For example, users only need to filter fishery organisms whose body length is greater than a certain limit value, and do not care about their average body length and quantity information; or users only need fishery organisms with a body length within a certain range, and care about their quantity and body length information , but do not care about the information of fishery organisms outside the body length range; or the user only needs to filter out fishery organisms whose body length is less than a certain limit value, and does not care about other fishery organisms and information; and various other possible special situation. In this mode, the user can program and set the simple operating mode in the central controller 30, select the mixed working mode, and input different body length requirements and limit values according to their own different needs, and specify the corresponding body length fishery The location of the fishery biological collection box for the biological output, and the data information requirements for the final generation of the report, etc. In essence, the mixed working mode is a special simplified version of the graded working mode, that is, the system first detects the size of fishery organisms one by one, and then judges that the currently detected fishery organisms meet the user's settings one by one according to the user's preset settings. Which type of requirements are specified, and the fishery organisms that meet the requirements of different specifications are transported to the corresponding fishery biology collection boxes, and finally a work report that meets the requirements is generated. Likewise, the suspended working mode can be applied in the mixed working mode, so as to facilitate the replacement operation of the fully loaded fishery biological collection tank. It can be found that under the mixed working mode, the calculation and judgment workload of the system is not significantly reduced, and some electric valves also maintain a continuous and frequent opening and closing working state, which cannot significantly reduce system work loss and improve work efficiency. Therefore, under normal circumstances, the hierarchical working mode is sufficient to meet the needs of users, and the application requirements of mixed working modes are relatively rare. However, when it is necessary to perform binary screening on the population of fishery organisms, that is, to screen out fishery organisms that are larger or smaller than a certain body length limit value, the mixed working mode is the best working mode choice.

In the pause mode, the system suspends the work of counting, detection, and grading, which is applied when a certain fishery biological collection box is full and needs to be replaced, or other situations that require the system to suspend work. Touch the pause work button in the central control 30 to start the pause work mode. After starting the pause command in the counting mode and the detection mode, when the No. 6 photoelectric detector 6 detects that the input of a fishery creature is completed, the central controller 30 sends an order to close the fifth electric valve 5 to stop the continued input of the fishery creature , but the system continues to complete the counting and detection of the currently input fishery organisms. After the suspension command in the grading mode and the mixed mode is started, the system does not immediately suspend the input work, detection work, or grading work of fishery organisms, but when the eleventh, fourteenth, and seventeenth One of the feedback signals of the photoelectric detector No. 5 has completed the detection and classification of the current fishery organisms, and no longer sends the command to the fifth electric valve 5 to open and put in the next fishery organisms, and the suspension of the system is officially started. model. The purpose of such setting is to prevent the sudden closing of the fifth electric valve 5 from causing harm to the input fishery organisms, or the system suddenly abandons the detection and classification work in progress, resulting in errors in the detection results and classification results. Then, the system temporarily stores all data information, each electric valve maintains the last working state, and the stable water flow input faucet 1 maintains the input of stable water flow to keep the system water flow unimpeded; at this time, the full-load fishery biological collection box can be replaced. Replace with new blank fishery biocollection boxes, or perform other necessary work. After the necessary suspend work is completed, the pause button in the central controller 30 can be touched again to release the suspend work state. The system first sends an open work command to the fifth electric valve 5, and continues to temporarily suspend according to the currently set work mode. Counting, testing, and grading work.
