Intelligent monitoring system of dangerous goods container transported by ship

Abstract

The invention discloses an intelligent monitoring system of a dangerous goods container transported by a ship, comprising an on-board automatic monitoring system, a remote transmission system and a monitoring center, wherein, the on-board automatic monitoring system realizes the real time perception of the on-board container condition by utilizing a monitoring terminal, a relay terminal and a convergence terminal for converging data arranged on the door of the container, transmits the collected condition information of the container to the remote monitoring center through a remote transmission system, and realizes the processing and alarming functions and the like of the collected condition information of the container at the front end. Through the networking of the monitoring terminal of the container based on a ZigBee technique, the system provided by the system solves the problem that the communication is temporarily interrupted caused by that the signals are shielded when a radio frequency identification device (RFID) or a general packet radio service (GPRS) / a global system for mobile communication (GSM), or a satellite is directly adopted as a communication module in the existing container monitoring system; and the system provided by the invention has the characteristics of high reliability and low communication cost and being easy to monitor, and provides an effective solution scheme for intelligently monitoring the dangerous goods container.

Description

technical field [0001] The invention relates to a container monitoring system. Background technique [0002] With the vigorous promotion of container transportation in the world and the increasing emphasis on the safety and efficiency of container transportation, especially dangerous goods container transportation, a large amount of funds have been invested internationally in the safety and intelligent technology of dangerous goods containers. In terms of equipment research, the importance of developing this field is increasingly recognized in China, and the development of related equipment has a certain technical basis. [0003] In the existing container monitoring system, the smart label installed on the container at the front end generally includes a sensor part and a wireless transmission part. The sensor part includes sensors for sensing the environmental status of the container in the cargo transportation environment such as temperature, humidity, vibration, etc. The ...

Problems solved by technology

[0004] However, the monitoring module installed on the container in the existing container intelligent monitoring system either uses radio frequency identification (RFID) technology to transmit the container status information sensed by the sensor module to the reader through active or passive means, or uses The most important thing is to directly transmit the data to the monitoring center via GPRS / GSM base station or satellite, so the interconnection between containers cannot be realized. When the containers are stacked in the yard or inside the cabin, some containers are blocked by other containers and are not in the RFID reader. In the direct line of sight, communication cannot be carried out; or GPRS / GSM signal, satellite signal is blocked and communication cannot be carried out
