Ship-borne hazardous article container wireless monitoring device with underwater positioning function and method thereof

Abstract

The invention discloses a ship-borne hazardous article container wireless monitoring device with an underwater positioning function and a method thereof. The device comprises a battery power supply unit, an attitude sensor, a cargo detection sensor set, a water falling detection sensor and an embedded microprocessor. When the embedded microprocessor is in an initial power-on state or does not receive a water falling state signal, a semiconductor switch is controlled to supply power to a radio frequency communication unit so that the device is enabled to be in a radio frequency communication mode, and all the acquired measuring signals are transmitted to a background monitoring center via the radio frequency communication unit; and when the water falling state signal is received, the semiconductor switch is controlled so that the device is enabled to be in an underwater acoustic communication mode, an underwater positioning signal is transmitted via an underwater acoustic signal transmit-receive interface circuit and an underwater acoustic energy converter, and underwater state information of a container is transmitted according to requirements. The ship-borne hazardous article container wireless monitoring device with the underwater positioning function is small in space occupation without influence on navigation and accurate in positioning, and can conveniently acquire container underwater attitude and the underwater state information of container hazardous article cargos.

Description

technical field [0001] The invention relates to a monitoring technology for a container falling into the water, in particular to a wireless monitoring device and method for a ship-borne dangerous goods container with an underwater positioning function. Background technique [0002] The goods loaded in dangerous goods containers are usually corrosive, flammable, explosive, and toxic. Once an accident occurs during transportation, it will bring huge hidden dangers to the safety of the ecological environment. Waterway is the main mode of transportation of dangerous goods containers. In order to timely grasp the state of dangerous goods containers on board during transportation and implement safety management on dangerous goods containers, it is necessary to realize real-time dynamic monitoring of key physical parameters of dangerous goods containers. At present, the monitoring of dangerous goods containers on board is usually realized by wireless sensor network technology. The ...
