Research and design of distributed intelligent electronic pulse barring facility

Because traditional barring facilities have difficulty in controlling the water surface and have low intelligence degree, a new type of intelligent electronic pulse barring facility was developed. The system established a dynamic charging and discharging model, an electric field strength calculation model, and a forward reverse rotation conduction model. The facility used a controller area network field bus to realize cooperative operation between one master machine and multiple slave machines that was suitable for fish blocking in various water areas. By using insulated gate bipolar transistors instead of thyristors, the electrode adopted an instantaneous rotational conduction mechanism that was efficient, safe, reliable, and resulted in low noise pollution. The system realized the application of the Internet of Things and an automatic fault phone alarm function in the aquaculture industry such that users could use phones or computers for real-time remote monitoring. A failure of the fish barring facility would immediately trigger an alarm, such that corresponding measures could be taken to avoid the escape of many fish and complete the unattended aquaculture industry. After multiple freshwater fish arresting tests, the load capacity of the whole machine was 0.5 Ω, and the power consumption was 0.3–2 kW; this could save 65% more electricity than traditional thyristors and had a maximum interception area of 1200 m². This has significant practical application value in improving the digitalization, automation, and intelligence level of the aquaculture industry.
