Invisible fish blockage control system based on network structure

Abstract

The invention discloses an invisible fish blockage control system based on a network structure. The invisible fish blockage control system comprises a master controller and a plurality of node controllers for controlling fish blockage, wherein the master controller is connected with each node controller through a controller area network (CAN) bus and monitors the operating states of the node controllers; the master controller comprises a master microprocessor, an operation and display processing module and a switching power supply module; the operation and display processing module is connected with the master microprocessor and selects the node controller through the master microprocessor and displays the operating state of the node controller; and the switching power supply module is connected with the master microprocessor, receives the control of the master microprocessor and supplies power to the node controller. According to the control system, multiple fish blockage equipment can be monitored in a unified mode, and the fish blockage out-of-control time is reduced; and moreover, the invisible fish blockage control system has the capacity of automatically adapting to various water areas, good fish blockage effect, long-term free maintenance and the capacity of continuously working all the year round.

Description

technical field [0001] The invention belongs to the technical field of automation equipment used in water area aquaculture, and in particular relates to an invisible fish blocking control system based on a network structure. Background technique [0002] In the 1990s, driven by economic interests, there was a frenzy of cage fish farming in lakes in China. Due to the long-term deposition of fish manure and remaining bait in the process of fish farming in cages, the water quality of the rippling lake water It has been severely damaged, directly threatening the safety of drinking water for Chinese people. At the beginning of the 21st century, under the supervision of government departments, all parts of the country began to control lake water across the country. According to Chongqing News, as the largest artificial freshwater lake in Southwest China, Changshou Lake was formed by truncating the Longxi River in the 1950s. There are more than 200 islands dotted around the lake, ...

Problems solved by technology

[0003] In order to develop the aquaculture industry in the water area without polluting the water quality of the water area, people have invented invisible fish blocking equipment. The control system of the existing fish blocking equipment is generally realized by multiple independent controllers without network structure, such as Publication No. CN102096379 is an intelligent deep-water fish catching / blocking main controller. The control area of ​​the main controller in each fish blocking device is extremely limited. Fishing devices are independent of each other and cannot be monitored uniformly. Special personnel are required to inspect whether the main controller of the fish-blocking device is faulty. If the faulty equipment is found in multiple fish blocking devices, the fish blocking time will be out of control for a long time, and more fish will escape within the out of control time, and the loss will be greater; fresh water, etc.), the pulse electric field generated by the underwater electrode controlled by it can only be adjusted manually (that is, the tap of the transformer is manually selected), and people cannot accurately judge the conductivity of the water quality, which leads to the effect of blocking fish Not good, fish are easy to escape; after long-term use of the underwater electrode controlled by the above-mentioned main controller, its surface is easily oxidized or calcified. After the electrode surface is oxidized or calcified, the electrode performance is unstable (that is, the generated pulsed electric field is unstable) , regular maintenance is required to ensure its fish blocking effect, and the operation is troublesome; the above-mentioned main controller uses a transformer to transform the one-way AC power supply and provide power to the main controller. If the power supply is abnormal or faulty, the main controller When it can't work, the fish blocking equipment will fail and can only be used after maintenance, which cannot meet the continuous and uninterrupted use for many years
