Description

Technical Field

[0001] The present invention relates to the technical field of seawater aquaculture, and in particular to a seawater aquatic animal driving platform and a breeding intelligent service system. Background Art

[0002] Marine aquaculture is an important way to sustainably utilize marine resources, and has biological resource advantages over traditional fisheries and inland agriculture. As we all know, my country's 1.8 billion mu of arable land red line is "getting tighter and tighter", and the pressure on agriculture and animal husbandry, which are closely related to land, has doubled. Therefore, my country's huge "blue arable land" will receive more and more attention.

[0003] At present, my country is the world's largest marine aquaculture country, with the largest aquaculture area and output in the world. Marine aquaculture plays a positive role in ensuring the supply of seafood, alleviating food security, improving the national diet and health level, promoting economic growth, and coping with the depletion of natural fishery resources. Although the marine aquaculture industry has made great achievements, we must also see the existing shortcomings. The main problems of marine aquaculture in my country are as follows:

[0004] First, marine aquaculture is mainly carried out in enclosures, and freshwater fish interceptors are not applicable.

[0005] Cage aquaculture is an important model with the characteristics of intensiveness and high density, but long-term high-density aquaculture also brings a series of problems, such as serious fouling of cage nets, poor water exchange capacity, deteriorating marine aquaculture environment, frequent outbreaks of aquaculture diseases, etc. In the aquaculture process, in order to create a good and enemy-free environment for aquatic products, the surrounding ecological environment is often sacrificed, and the ability to resist diseases and risks drops sharply, which is very likely to cause regional aquaculture disasters and accidents.

[0006] Aquatic animals enter the water intakes of hydropower stations and pumping stations, and are killed or disabled by the high-speed rotating impellers, resulting in the death of a large number of aquatic animals and causing serious damage to the water ecology. In recent years, in order to improve and strengthen water ecological protection, my country has forced various water intakes to install aquatic animal isolation devices. The traditional interception method is to use metal fences to block aquatic animals from passing through. However, while the metal fences block aquatic animals, they also block floating objects such as garbage, branches, and weeds in the water, and will soon lose their water-repellent ability. Frequent cleaning of floating objects has become the most arduous task at the water intake, and the conflict between ecological protection and water extraction for power generation, irrigation, and drinking water has become irreconcilable.

[0007] Seawater conductivity is a physical quantity used to indicate the electrical conductivity of seawater. The conductivity of seawater is not only more than a thousand times greater than that of ordinary lake water and river water, but also has strong corrosiveness. In addition, the aquaculture area of ​​seawater is larger than that of freshwater reservoirs, and there are many species of organisms. The general electric fence to intercept fish is no longer suitable for seawater aquaculture.

[0008] Second, my country's marine environment is not optimistic, and the safety of marine aquaculture is becoming increasingly prominent.

[0009] First, the seawater is often polluted due to sand extraction, mining and illegal discharge of pollutants by coastal enterprises in the upper reaches of the river.

[0010] Second, high-density aquaculture generally involves the use of large amounts of organic, inorganic or high-efficiency compound fertilizers for artificial feed. These feeds contain high levels of phosphorus and nitrogen, and long-term use can cause eutrophication of seawater or red tides. Some people also use chemical additives during the aquaculture process, and toxic excrement will change the chemical balance of the water body, leading to an increase in the degree of eutrophication of the water body, which will not only affect the survival of other marine organisms or kill a large number of algae, plankton and shellfish, but also threaten human health through the food chain.

[0011] "To raise fish, you must first raise water." The quality of the water environment will directly determine the quality of aquatic products. The oxygen content, pH value, temperature, and dissolved oxygen of seawater are important parameters that reflect the state of seawater, which directly affect the output and quality of marine aquaculture. It is very necessary to achieve real-time online monitoring and change trends of the above parameters.

[0012] At present, domestic aquaculture environment monitoring mostly adopts manual methods, which is time-consuming and labor-intensive. Some companies or farmers use online real-time monitoring equipment, but most of them still use wired transmission methods. When the breeding area is large, they will face a large number of wiring problems at the monitoring points, which brings many inconveniences to system installation, maintenance and technical upgrades.

[0013] With the development of Internet of Things, VLSI and embedded system technology, marine aquaculture environment detection technology urgently needs to develop from traditional methods such as test paper reagent detection with single detection and inconvenient data processing to automatic testing systems with high digital integration, high real-time performance and flexible and convenient matching, so that users can monitor the on-site seawater quality environment information anytime and anywhere.

[0014] Third, management level and efficiency need to be improved urgently

[0015] The development of modern marine aquaculture requires advanced facilities, feed, technology, management, information, capital and many other factors. Individual farmers are constrained by cultural knowledge, professional quality, financial level and traditional agricultural thinking, and are slow to absorb and transform new concepts and technologies. They use more labor to replace more expensive capital, and the level of aquaculture technology is generally low, the aquaculture structure is unreasonable, and the production and management methods are relatively extensive, resulting in greater production and quality safety risks in the marine aquaculture industry.

[0016] With the rapid development of marine aquaculture, how to achieve the transition from extensive aquaculture management to careful, scientific and efficient management based on intelligent information processing systems has become one of the most prominent and urgent issues to be solved in the transformation of marine aquaculture from disorder to order. It is also an important means and effective way to accelerate transformation and upgrading.

[0025] Completely different from the concept of this patent. Summary of the invention

[0026] Purpose of the invention: To provide a better marine aquatic animal driving platform and aquaculture intelligent service system. The specific purpose can be seen in the multiple substantial technical effects of the specific implementation part.

[0027] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0028] The seawater aquatic animal driving platform is characterized by:

[0029] The driving platform comprises a plurality of movable hanging metal electrodes, which constitute a movable electronic fence, and the plurality of movable hanging metal electrodes are hung on steel strands, which are fixed on cement columns;

[0030] The electronic fence is arranged at the water intake of the marine aquaculture farm to form an invisible stimulating current field to drive away aquatic animals and not allow them to enter the water intake; the water inlet electrode is suspended from the bottom of the waterway;

[0031] Electronic pulses are set on multiple movable hanging metal electrodes.

[0032] The pulse current passes through the electrode to form an electric field on the fish intercepting section in the water. When the fish approaches the electrode, they feel the weak current and will instinctively escape to the direction of the weaker electric field after being stimulated, thus achieving the purpose of driving away and preventing escape.

[0033] The movable electronic fence has the advantage of not blocking water debris, and floating objects can pass smoothly through the movable hanging metal electrodes.

[0034] A further technical solution of the present invention is that the positive and negative connections of adjacent electrodes of a plurality of movable hanging metal electrodes are inconsistent, and one of the adjacent hanging metal electrodes is connected to the positive electrode and the other is connected to the negative electrode.

[0035] A further technical solution of the present invention is that the steel strand is suspended above the water surface at a height greater than 1.2m, and the water entry electrode is hung on the steel strand at a certain interval, and the steel strand is the carrier of the water entry electrode; the water entry electrode is suspended from the bottom of the waterway to avoid the formation of a current loop between the bottom of the waterway and the electrode, thereby avoiding unnecessary consumption of pulse power; an electric ceramic or bakelite tension insulator is used to isolate the electrical circuit between the electrode and the steel strand, thereby eliminating the risk of electric shock to humans and animals;

[0036] The main unit of the electronic driving device generates 500V to 700V, with a frequency of 3 to 12Hz; a peak pulse power current with a pulse width of about 1ms is applied to the electrode; the electronic fence is perpendicular to the water flow direction at 90 degrees and is placed horizontally at the water intake, thereby forming a stimulating current wall at the water intake;

[0037] The stimulation current distribution field is an electric field unit formed by straight lines and arcs flowing from the positive electrode to the negative electrode. Multiple electric field units are connected in series to form a stimulation current wall. The pulse power signal parameters can stimulate the nerves of animals using electric pulses without harming aquatic organisms. The discomfort caused forces aquatic animals to swim back, thereby achieving the purpose of driving them away or preventing them from escaping. The electrodes are suspended in the air and can swing freely without retaining water debris, thus ensuring that the waterway is unobstructed.

[0038] A further technical solution of the present invention is that the pulse signal is generated by a pulse electrical signal generating device, namely a pulse host, which includes

[0039] Including power supply unit module, capacitor energy storage unit module, pulse power signal generator module, IGBT drive circuit module, surge protection absorption circuit module, signal acquisition circuit module;

[0040] The power supply unit module is used to access the power supply, the capacitor energy storage unit module is used to store energy, the pulse power signal generator module is used to control the emission of pulse current, the IGBT drive circuit module is a composite fully controlled voltage-driven power semiconductor device, which has the characteristics of high input impedance of MOSFET and low conduction voltage drop of GTR; the signal acquisition circuit module is used for signal isolation and pulse signal capture;

[0041] It also includes a host controller and a plurality of slave controllers for controlling the driving away of aquatic animals in seawater; the host controller and the slave controllers are connected wirelessly to one master and multiple slaves, and perform long-distance, high-speed, and large-capacity data communication, so as to be applicable to the driving away of aquatic animals in large seawater areas and under high conductivity;

[0042] The host controller uses transformers and capacitors to store energy and rectify into different bus DC high-voltage gears; the host generates a sequence of slave bus discharge pulses to control the IGBTs of different slaves to conduct in turn, and the high-voltage DC is discharged through electrodes in the water to drive away aquatic animals. The conduction time and frequency are adjustable; the device uses IGBT to replace the thyristor used in traditional electric fence fish interception equipment, which is not only efficient, safe and reliable, but also has a commutation function, which can avoid the safety hazard of failure due to surface oxidation or calcification after the electrode is turned on for a long time.

[0043] The host external sensor automatically adjusts the frequency, the analog input 4~20mA and the output pulse frequency 2~12Hz are proportionally linearly correlated, and the touch screen can set the automatic frequency adjustment mode / manual frequency adjustment mode; once the system fails, the output pulse will be suspended and the sound and light alarm will be issued at the same time;

[0044] The system can output two inverted pulses with a certain frequency and pulse width. The touch screen can set the output in H-bridge mode or creeping mode. In H-bridge mode, the frequency range is set to 2-12Hz, and the output frequency of the microcontroller is 1-6Hz; in creeping mode, the frequency range is set to 2-12Hz, and the output frequency of the microcontroller is 2-12Hz.

[0045] The touch screen human-machine interface communicates data with the host, which is used for system configuration and parameter setting on the one hand; and for monitoring the working status of the marine aquatic animal driving device on the other hand. The system has the functions of automatic fault telephone alarm, mobile phone or computer remote monitoring, which is convenient for operators to conduct timely inspection and maintenance, and master the operating status of the system without leaving home, reducing the workload of patrol personnel, minimizing user losses, and realizing the function of Internet + marine fishery.

[0046] The host selects the appropriate bus discharge frequency and pulse width according to parameters such as conductivity to achieve modular functions; after the system is initialized, the A / D conversion module will automatically collect seawater conductivity and display the value on the touch screen; select appropriate pulse frequency and pulse width and other parameters; the controller outputs two anti-phase pulses to control the operation of the IGBT driver board, and the bus high voltage passes through the electrode to form a special electric field in the water to achieve the purpose of blocking fish; if the system is abnormal, an audible and visual alarm will be issued, and the touch screen will display specific fault information, prompting the operator to conduct troubleshooting in time to avoid losses to farmers;

[0047] The slave controller receives the control pulse, generates a pulse with preset width and period, and transmits it to the IGBT driver board. The driver board controls the IGBT to switch on, thereby applying DC power to the electrodes in the water for discharge to drive away aquatic animals. In order to prevent instantaneous surge current from damaging the IGBT, the IGBT is equipped with surge absorption protection. The signal acquisition board collects the operating frequency and fault condition parameters of the slave, which are then fed back to the host controller through the Internet of Things by the slave controller for monitoring.

[0048] The aquaculture intelligent service system is characterized in that it utilizes the seawater aquatic animal driving platform as described in any one of the above items, and further includes an aquaculture environment monitoring system, which selects temperature, dissolved oxygen, pH value, drug residue, and conductivity sensors that can adapt to the aquaculture environment of fish, shrimp, and ginseng, and then transmits the seawater aquaculture environment data to the service platform through a wireless network and the Internet of Things for processing and display;

[0049] The online water quality monitoring system for marine aquaculture mainly adopts the layout of wireless sensor networks to collaboratively sense, collect, process and transmit marine aquaculture environmental parameter information;

[0050] The sensors of the marine aquaculture water quality monitoring system collect values ​​at regular intervals and send them to the STC15W408AS controller; the STC15W408AS controller is powered by cables and transmits data to the wireless transmission module at the same time. The wireless transmission module can temporarily store the data collected by the sensors, and then summarize the data of all monitoring nodes through the Internet of Things and transmit it to the collection APP or remote computer and other monitoring terminals for processing and display.

[0051] A further technical solution of the present invention is that it also includes an information management and query system, which includes subsystems such as personnel management training, biological breeding and capacity, sales logistics engineering, home drying forecast and prevention, and item facility management, which can count and analyze the marine aquaculture environment, breeding species, breeding volume, output and benefits, provide auxiliary support for marine ecological breeding decision-making, and reduce breeding risks.

[0056] The aquaculture income evaluation subsystem includes the price changes of production materials such as feed, medicine, facilities, equipment, and the market price changes of aquatic animals. The Markov chain model is used to predict price changes to calculate the income and draw a curve chart.

[0057] A further technical solution of the present invention is that the marine aquaculture environment monitoring system diagnoses the working status of the system and issues real-time alarms for various faults and abnormal conditions. The main functions are as follows:

[0058] The real-time environmental monitoring subsystem draws real-time and historical curves of various parameters. The historical curves or data can be imported, exported, and queried under conditions. The maximum, minimum, and average values ​​of each parameter data are calculated and counted, and interfaces with environmental monitoring equipment are reserved for expansion.

[0059] A further technical solution of the present invention is that the aquaculture environment assessment subsystem uses a numerical model to simulate the impact of different aquaculture modes on the environment;

[0061] The user of the pollutant dynamic behavior prediction subsystem only needs to input parameters such as pollutant type, quantity, meteorological conditions, etc. for simulation, and the data will be displayed in the form selected by the user, so that the user can take necessary measures to reduce losses according to the diffusion path.

[0062] The present invention adopting the above technical solution has the following beneficial effects compared with the prior art: This patent is an effective, safe and advanced intelligent service platform for aquaculture, which plays a role in intercepting and preventing escape, and can fundamentally overcome the limitations of mechanical fish intercepting facilities.

[0074] This patent provides a variety of parallel solutions. The different expressions are improved solutions or parallel solutions based on the basic solution. Each solution has its own unique characteristics. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. The fixing method not described in the text can be any fixing method such as thread fixing, bolt fixing or glue bonding.

[0075] Embodiment 1: In conjunction with all the accompanying drawings; a seawater aquatic animal driving platform, characterized in that:

[0076] The driving platform comprises a plurality of movable hanging metal electrodes, which constitute a movable electronic fence, and the plurality of movable hanging metal electrodes are hung on steel strands, which are fixed on cement columns;

[0077] The electronic fence is arranged at the water intake of the marine aquaculture farm to form an invisible stimulating current field to drive away aquatic animals and not allow them to enter the water intake; the water inlet electrode is suspended from the bottom of the waterway;

[0078] Electronic pulses are set on multiple movable hanging metal electrodes.

[0079] The pulse current passes through the electrode to form an electric field on the fish intercepting section in the water. When the fish approaches the electrode, they feel the weak current and will instinctively escape to the direction of the weaker electric field after being stimulated, thus achieving the purpose of driving away and preventing escape.

[0080] The movable electronic fence has the advantage of not blocking debris in the water, and floating objects can smoothly pass through the movable hanging metal electrode. The substantial technical effects and implementation process of the technical solution here, i.e. the basic functions, are as follows:

[0081] Electric fence layout diagram Figure 1 The electric fence consists of a water intake, steel strands, insulators, stainless steel electrodes and conductors, which are key devices for releasing electronic pulses to stimulate current into the water.

[0082] The steel strand is suspended above the water surface at a height of more than 1.2m. The water entry electrode is hung on the steel strand at a certain distance. The steel strand is the carrier of the water entry electrode. The electrode spacing ranges from 1.3 to 2m, the outer diameter ranges from 20 to 32mm, and the wall thickness is greater than 2mm. The water entry electrode is suspended from the bottom of the waterway to avoid the formation of a current loop between the bottom of the waterway and the electrode, and to avoid unnecessary consumption of pulse power; use power ceramic or bakelite tension insulators to isolate the electrical circuit between the electrode and the steel strand, and eliminate the risk of electric shock to humans and animals.

[0083] The main unit of the electronic drive device generates a peak pulse power current of 500V to 700V, a frequency of 3 to 12Hz, and a pulse width of about 1ms, which is applied to the electrode. The electronic fence is perpendicular to the water flow direction at 90 degrees and is placed horizontally at the water intake, thus forming a stimulating current wall at the water intake.

[0084] Figure 2 The figure shows the distribution field of the stimulation current from a bird's eye view. It is a unit formed by straight lines and arcs flowing from the positive electrode to the negative electrode. Multiple units are connected in series to form a stimulation current wall. The pulse power signal parameters can stimulate the nerves of animals with electric pulses without harming aquatic organisms. The discomfort caused forces aquatic animals to swim back, thereby achieving the purpose of driving them away or preventing them from escaping. The distance between the electrodes is about 2m, and they can swing freely when suspended in the air. They will not retain water debris, ensuring that the waterway is unobstructed, which completely solves the contradiction and shortcomings of isolating aquatic animals and blocking the water.

[0085] The hardware device for driving away seawater organisms with electronic pulses includes power supply unit, capacitor energy storage unit, pulse power signal generator circuit, IGBT drive circuit, surge protection absorption circuit, signal acquisition circuit and other modules. The system network structure diagram is as follows: Figure 3 As shown. The control system includes a host controller and multiple slave controllers for controlling the expulsion of seawater aquatic animals. The host and the slaves use wireless methods to establish a master-multiple-slave connection and perform long-distance, high-speed, and large-capacity data communication, so as to meet the needs of expelling aquatic animals in large seawater areas and high conductivity.

[0086] The touch screen human-machine interface communicates data with the host, which is used for system configuration and parameter setting on the one hand, and for monitoring the working status of the marine aquatic animal driving device on the other hand. The system has functions such as automatic fault telephone alarm, mobile phone or computer remote monitoring, etc., which is convenient for operators to conduct timely inspection and maintenance, and master the operating status of the system without leaving home, reducing the workload of patrol personnel, minimizing user losses, and realizing the design concept of Internet + marine fishery.

[0087] The main chassis is composed of Figure 4As shown. The host uses transformers and capacitors to store energy and rectify into different busbar DC high-voltage gears. The host generates the slave busbar discharge pulse sequence timing to control the different slave IGBTs to conduct in turn. The high-voltage DC is discharged through the electrodes in the water to drive away aquatic animals. The conduction time and frequency are adjustable. The device uses IGBT to replace the thyristor used in traditional electric fence fish interception equipment. It is not only efficient, safe and reliable, but also has a commutation function, which can avoid the safety hazard of failure due to surface oxidation or calcification after the electrode is turned on for a long time.

[0088] The host external sensor automatically adjusts the frequency, the analog input 4~20mA and the output pulse frequency 2~12Hz are proportional and linearly correlated, and the touch screen can set the automatic frequency adjustment / manual frequency adjustment mode. Once the system fails, the output pulse will be suspended and the sound and light alarm will be issued at the same time.

[0089] The system can output two inverted pulses with a certain frequency and pulse width. The touch screen can set the output in H-bridge mode or peristaltic mode. In H-bridge mode, the frequency range is set to 2 to 12 Hz, and the output frequency of the microcontroller is 1-6 Hz; in peristaltic mode, the frequency range is set to 2 to 12 Hz, and the output frequency of the microcontroller is 2-12 Hz.

[0090] The system can remotely monitor the frequency, pulse width, circuit working status (running / stopping / fault), and cumulative startup time through a mobile phone or host computer; or remotely start and stop, and set automatic / manual frequency modulation mode.

[0091] The host selects the appropriate bus discharge frequency and pulse width according to parameters such as conductivity to achieve modular functions. After the system is initialized, the A / D conversion module will automatically collect the seawater conductivity and display the value on the touch screen. The appropriate pulse frequency and pulse width and other parameters are selected through the theoretical calculation model. The controller outputs two anti-phase pulses to control the operation of the IGBT driver board, and the bus high voltage is formed through the electrode in the water to form a special electric field to achieve the purpose of blocking fish. If the system is abnormal, an audible and visual alarm will be issued, and the touch screen will display specific fault information, prompting the operator to conduct troubleshooting in time to avoid losses to farmers.

[0092] From the chassis Figure 5 As shown. The slave chassis is mainly composed of a slave controller, an IGBT driver board, an anti-surge absorption circuit board, a signal acquisition board, a DC power supply, etc. The slave controller receives the control pulse, generates a pulse of preset width and period, and transmits it to the IGBT driver board. The driver board controls the IGBT to switch on, thereby applying the DC power supply to the electrodes in the water for discharge to drive away aquatic animals. In order to prevent the instantaneous surge current from damaging the IGBT, the IGBT is equipped with anti-surge absorption protection. The signal acquisition board collects the operating frequency and fault parameters of the slave, and then the slave controller feeds back to the host controller through the Internet of Things for monitoring.

[0093] The aquaculture environment monitoring system selects sensors such as temperature, dissolved oxygen, pH value, drug residues, and conductivity that can adapt to the aquaculture environment of fish, shrimp, and ginseng, and then transmits the marine aquaculture environment data to the service platform through wireless networks and the Internet of Things for processing and display.

[0094] The online water quality monitoring system for marine aquaculture mainly adopts the layout of wireless sensor networks to collaboratively sense, collect, process and transmit marine aquaculture environmental parameter information. It has the characteristics of low power consumption, low cost, distribution and self-organization. Figure 6 shown.

[0095] The marine aquaculture water quality monitoring system mainly consists of sensors, single-chip microcomputers, and display terminals. The sensors collect values ​​at regular intervals and send them to the STC15W408AS controller. The controller is powered by cables and transmits data to the wireless transmission module at the same time. The wireless transmission module can temporarily store the data collected by the sensors, and then aggregate the data of all monitoring nodes through the Internet of Things and transmit them to the monitoring terminal such as the collection APP or remote computer for processing and display.

[0096] In order to further rationally utilize the sea area, effectively solve the relationship between aquaculture technology, ecological environment and resource allocation, integrate and optimize aquaculture resources, reduce human errors, effectively avoid aquaculture risks, and maximize social, economic and ecological benefits, the aquaculture smart service platform provides all-round real-time monitoring and scientific strategy guidance for marine aquaculture.

[0097] The entire service platform includes a seawater electronic pulse drive monitoring system, a seawater aquaculture environment monitoring system, and an information management and query system. The specific functions are as follows: Figure 7 shown.

[0098] The smart service platform first measures the seawater conductivity parameter value, sets the pulse, frequency and number of slaves according to the seawater conductivity value, and performs fault detection and alarm for drive and communication. Once a system failure occurs, an automatic fault telephone alarm will be issued. In addition, using virtual computer remote technology, remote control can also be performed using a host computer or mobile phone.

[0099] The information management and inquiry system includes subsystems such as personnel management and training, biological breeding and capacity, sales logistics engineering, home drying forecast and prevention, and item facility management.
