WSN (wireless sensor network) based fire monitoring system for ship bridge

Abstract

The invention discloses a WSN (wireless sensor network) based fire monitoring system for a ship bridge, which comprises a ship host computer system, an on-site monitoring subsystem, a fire warning information display terminal and a ship-borne gateway, wherein the fire information display terminal is connected with the ship host computer system, and the ship host computer system is connected with the ship-borne gateway; the ship-borne gateway is connected with the on-site monitoring subsystem, and the on-site monitoring subsystem comprises a communication equipment monitoring area, a navigation equipment monitoring area, a meteorological equipment monitoring area, a distress alarm equipment monitoring area and a chart room monitoring area; and each monitoring area is connected with corresponding ship-borne wireless sensor equipment. The WSN based fire monitoring system utilizes wireless sensor nodes to monitor the temperature and smoke within the target area, gases generated by combustion of bridge equipment and other fire indicator information in real time, and periodically packages and sends monitoring data to the host computer monitoring system to ensure the safety of navigation of a ship.

Description

technical field [0001] The invention relates to the field of wireless sensor networks, that is, a ship bridge fire monitoring system derived based on WSN; in particular, it relates to a ship bridge fire monitoring system based on WSN. Background technique [0002] When ships are developing toward electrification, automation, and large-scale development, the types and power of electrical equipment on ships, especially bridges, are also increasing, and the fire hazards caused by electrical equipment are also greatly increasing. Moreover, the ship's bridge stores various equipment needed for ship navigation, such as internal communication equipment, VHF and MHF combined radio stations, GPS (Global Satellite Positioning System), radar, log, automatic clock recorder, Electronic charts, emergency radio position indicating beacons, etc. These electrical equipment need to work in a constant voltage, stable, and dry environment, but they have been in a humid and vibrating space for ...

AI Technical Summary

Problems solved by technology

Due to the narrow interior space of the ship, the passages and stairs in the cabin are relatively narrow, most of the cabin doors and entrances can only accommodate one person through

Moreover, the ship's bridge is usually located on the upper deck of the ship. If a fire breaks out on the bridge, it is difficult for the staff on board to quickly reach the fire scene of the bridge on the upper deck of the ship through the narrow cabin passages and stairs, and the width of the cabin passages and stairs is virtually limited. The speed at which the crew transports the fire-fighting equipment on board through the cabin passages and stairs virtually reduces the fire-fighting efficiency of the fire-fighting equipment on board the ship. Disasters wrought by ships are devastating
