Control system of fishing boat cabin ventilation equipment

Abstract

A control system of fishing boat cabin ventilation equipment comprises a main control display terminal and at least one monitoring device. The main control display terminal comprises a power supply management module, a main control board and a display screen. The main control display terminal is provided with a ventilation signal control interface, which is used for being connected with ventilation equipment. The power supply management module converts alternating current into direct current and provides a stable power supply for the system. The main control board is used for calculating and converting the data detected by each monitoring device to obtain a digitized result, sending the digitized result to the display screen for display, judging the data and starting the ventilation equipment when the concentration of hydrogen sulfide exceeds the standard. The monitoring device is composed of an H2S detector and a monitoring main board. The monitoring main board receives electric signals from the detector, converts the electric signals into a digital signal, and sends the digital signal to the main control display terminal for display. The system can detect and control the concentration of hydrogen sulfide in the cabin of the fishing boat, and thus safety accidents caused by over-high concentration of hydrogen sulfide are avoided.

Description

technical field [0001] The invention relates to hydrogen sulfide monitoring technology, in particular to a control system for cabin ventilation equipment of fishing boats. Background technique [0002] Fishing vessels, that is, fishing vessels, are collectively referred to as vessels for fishing, processing, and transporting fish. Vessels for surveys, fishery guidance and training, and fishery administration tasks. The materials in the cabins of fishing boats are prone to deterioration and produce a large amount of hydrogen sulfide, which is a flammable and toxic gas. If it is not evacuated in time, it is easy to cause poisoning. For example: On May 8, 2016, due to the hot weather, the fish and shrimp in the cabin of the Fujian "Minshiyu 06351" boat rotted, and the harmful gas produced caused four fishermen to fall down one after another. On November 28, 2015, four fishermen on the "Zhexiangyu 10013" fishing boat suddenly suffered from hydrogen sulfide poisoning, and two o...

AI Technical Summary

Problems solved by technology

However, just to set up the ventilation equipment, often due to the negligence of the crew, the equipment is not turned on in time, resulting in the ventilation equipment being ineffective, and the hydrogen sulfide poisoning tragedy cannot be avoided.
