Siemens combines RFID, sensors, GSM and satellite technology to achieve container tracking at sea

Siemens IT Solutions and Service Center has launched an RFID experimental product test project, which can be used to monitor containers during shipping. The company claims that the test shows that the device fills a gap in the current commercial cargo RFID monitoring system, that is, it cannot track the cargo’s transportation process on the ocean.
“Our tests have confirmed that it is possible to achieve continuous monitoring of containers-from the seaport to the destination -, said Stefan von der Heide, head of Siemens IT Solutions and Service Center Mogis (Mobile GSM Infrastructure Over Satellite).
Siemens IT Solutions and Service Center plans to use more labeled containers and multiple satellite connections to carry out tests again. The company is also considering the promotion of this set of cargo solutions. As it is currently in negotiation with its partners, it declined to disclose details.
Siemens IT Solutions and Service Center has launched an RFID experimental product test project, which can be used to monitor containers during shipping.
In order to develop this Mogis system, Siemens IT Solutions and Service Center cooperated with Nokia Siemens Networks (Nokia Siemens Networks), which provided the GSM communication infrastructure required for the solution, a small version of the cellular telephone network. TriaGnoSys has developed satellite communication components. The main application of Mogis is to enable GSM to cover places that are not currently covered, such as ships at sea, disaster sites and airplanes. By introducing RFID in the program, the system can track containers on the high seas.
The tracking of shipping containers is very important to ensure food safety. “If a temperature alarm is triggered on the container in Shanghai, the end user can be notified immediately and rebook the loan without waiting for the goods to arrive at the port.” von der Heide said.
In cooperation with a group of most confidential business partners, Siemens IT Solutions and Service Center conducted this test in March this year. The solution uses RFID tags and sensors. The collected RFID data is sent to the ship’s GSM and GPRS communication networks, which are connected to a satellite communication service operated by Inmarsat.
In the test, the staff installed an 8-inch wide and 11-inch long box on two refrigerated containers. The ship departed from Shanghai to Singapore, and then returned. It took a total of three weeks. The box contains an active RFID tag connected to two sensors. One sensor is used to record the opening or closing of the container door, and the other is used to monitor the temperature inside the container.
The RFID tag of each container transmits its ID number and sensing data to an RFID reader. The reader then sends the information through the GSM base station to a control system on the ship, which then sends the information through satellites to a monitoring center monitored by the central monitoring center. Ground system.
“The monitoring center then informs the end user of relevant information,” von der Heide said. “However, if the end user is interested, the tracking box can directly send the alarm information to the user’s mobile phone.”
During this test, except for the bad air that affected the operation of the satellite, there was no error in the system operation under other conditions.
