Application of RFID Technology in Ship Dangerous Goods Transportation Management

The transport of crude oil and liquefied gas belongs to the transport of dangerous goods, and western countries have adopted the whole process of monitoring the transport of dangerous goods, monitoring the temperature, humidity, pressure and concentration of dangerous goods in the process of transport, which can help to realise the safe transport of the ship, and at the same time can help to take measures in a timely manner when abnormal conditions are detected, so as to reduce the loss of materials and personnel caused by the leakage or explosion of dangerous goods.

The traditional transport management of dangerous goods on board ships mainly realises the monitoring of goods on board ships by means of manual and semi-automatic electronic monitoring, and sends out the travelling coordinates and goods status of the ships through GPS and AIS, etc. Although the monitoring of dangerous goods on board ships can also be realised in this way, a lot of operations still need to be completed by the crews, and thus the efficiency is low. The wireless radio frequency technology mainly is through the electronic label information reading and the transmission to realise to the ship dangerous goods transport management, through the electronic label can directly obtain the ship loads the dangerous goods the type, the basic information, the departure place, the destination and some other necessary information. At the same time can through the regular automatic scanning electronic label, and with the real-time collection sensor monitoring data can complete to the ship dangerous goods real-time monitoring. The whole dangerous goods transport management process can realise the informationization and the automation, therefore greatly enhances the management efficiency, at the same time in the dangerous goods data acquisition and the processing also more accurate, the real-time is better. In wireless radio frequency technology, many scholars have researched the application of related technology in the management of dangerous goods transport.

Radio Frequency Identification (Radio Frequency Identification, RFID) is an important application of radio frequency technology, is the realization of the key subsystem of the ship dangerous goods transportation management.RFID system can realize the dangerous goods information writing and reading.

A basic RFID system includes 4 parts: electronic tag, reader, middleware and computer network.

(1) electronic tags
Electronic tags have control module, memory, radio frequency module and antenna, etc., which control module is responsible for under the control of the clock through the radio frequency module and antenna to memory read data or write data. The electronic label can be built-in power supply, also can obtain the energy from outside.

(2) Read-write
Read-write mainly through produces the clock, the radio frequency module and the antenna to read-write the electronic label data information, at the same time read-write internal also is responsible for provides the power supply.

3）Middleware
The middleware is responsible for the basic connection between the read-write and the computer network system, the general middleware is the upper layer software application and the bottom layer hardware connection between the part, but in the dangerous goods transportation management, may for the specific ship dangerous goods transportation management system design the specific middleware, causes it to have the function which reduces the interference, the read-write more reliable.

4) Computer Networks

The tag information obtained by the reader needs to be sent out through the middleware and the network so that it can be integrated with other subsystems of the ship transport management system. so that it can communicate and connect with other subsystems of the ship transport management system. to communicate and connect with other subsystems of the ship transport management system, and finally send the information to the control centre.

Every year, a large amount of dangerous goods are transported by sea to their destinations. In the process of transporting dangerous goods, there are risks of explosion, leakage and corrosion. During the transport, there are risks of explosion, leakage and corrosion, and therefore, it is necessary to carry out real-time monitoring and management of these dangerous goods during the transport. This paper describes the development of radio frequency identification (RFID) technology for the transport of dangerous goods. This paper describes the radio frequency identification (RFID) This paper describes the RFID technology and analyses the RFID system, tag anti-collision and middleware technology. technology is analysed.
