Description

Cargo status monitoring device for liquid cargo carrier

technical field

The utility model relates to a cargo state monitoring device for an easy-flowing cargo transport ship, which belongs to the technical field of ship engineering.

Background technique

The "International Maritime Solid Bulk Cargoes Code" (IMSBC Code) has now been enforced, and the rules govern ships' solid bulk cargoes in groups A, B and C. Among them, the goods in Group A are liquid goods. It is composed of a certain proportion of fine particles and a certain amount of water. If the water content exceeds a certain level during sea shipment, it may become fluidized and then form a fluid state. After fluidization, the viscosity and density of this kind of cargo are relatively high, and its lateral movement in the cargo hold will weaken the stability of the ship, cause the ship to heel, and even cause the ship to capsize in severe cases. According to the statistical report on dry cargo ship accidents from 2005 to 2015 released by the International Dry Cargo Ship Owners Association in May 2016, the fluidization of dry bulk cargo on board has become a major accident hazard for the safe transportation of dry bulk cargo in the past 10 years .

According to the IMSBC rules, currently the safety of liquefied cargo is ensured mainly by controlling the moisture content of the cargo by sea. In practice, the determination method and accuracy of transportable moisture limit (TML) for each cargo are still controversial. The sample selection in the TML test and the influence of rain in the loading process after the test are all uncontrollable factors affecting the TML. Therefore, even if the moisture content meets the current shipping requirements, the possibility of fluidization during sea transportation cannot be completely eliminated.

It can identify high-speed moving objects and simultaneously Identify multiple radio frequency cards, and the operation is fast and convenient. GPS mobile positioning, combined with GPS satellite signals and GPRS, CDMA network signals for hybrid positioning. When the terminal can receive GPS satellite signals, the GPS positioning method is used. When the terminal is indoors or in an environment where the satellite signal is not good, the auxiliary satellite signals received by the GPRS and CDMA base stations are used to achieve auxiliary positioning to meet indoor and outdoor full-coverage positioning. At the same time, effective use of communication satellite, GPRS, CDMA communication technology to complete remote information exchange. The monitoring and management platform is composed of GIS system, electronic map, vehicle, cargo monitoring, modules and other hardware. The main functions of the monitoring platform include "various operations of electronic map", "latest position", "timing tracking", "real-time tracking", " "Historical trajectory", "Cross-area (line) alarm" and various reports formed according to needs.
