Description

RF middleware system for container security device

The present invention relates to container security, and more particularly, to an RFID middleware system for a container security device that conforms to a CSD communication protocol and supports multiple interfaces to a reader and a database to enable various heterogeneous compatibility.

Freight transportation by container takes several steps, including loading, trucking, gate-in, loading, sailing, unloading, gate-out, trucking, and unloading.

Mechanism for monitoring the safety of the container and its contents has emerged as an important issue in the cargo transportation process using such containers.

The requirements of the current container security system are as follows.

The United States, which accounts for a large portion of freight shipments using containers, calls for a stronger container security system under the SAFE Port Act, and tightened container safety and security regulations, including the July 2007 Container Security Initiative (CSI) Agreement. have.

Necessary items to satisfy this problem include providing the sealing history of the container from the shipper to the receiver, providing history such as temperature / humidity / shock / illuminance detection for checking the state of the container, and providing real-time base passage information and location tracking information.

In addition, customer requirements are shifting from cost reduction to service aspects such as safe transportation of cargo, tracking of cargo status / location, and rapid customs clearance.

However, the current container security system is difficult to provide the container seal history from the Songhwaju to the receiver, and there is a limit in providing real-time base pass information, location tracking information.

In addition, even though the communication environment used for providing the container seal history, real-time base pass information, location tracking information has rapidly developed, it does not provide a security system that can actively use it.

In addition, container security systems suitable for various standards, such as transportation environment, communication environment, and container security environment, which are constructed differently by country and service provider, are not provided.

In particular, in the United States, from July 2012, inspection of all container cargoes imported into the United States is expected, and it is expected to mandate attachment to the Container Security Device (CSD).

If the container is not attached to the CSD, the whole inspection will be carried out. The inspection period is 3-7 days and the cost will be about $ 2000. Therefore, the loss is expected to be huge. Work is in progress to strengthen regulations.

At the end of 2007, the US Department of Homeland Security (DHS) issued a standard for container security devices (CSD), and the development of improved container security devices is in progress in Korea.

However, although the research on the hardware side is continuously progressed, the software research that complies with the CSD RFI has not been conducted.

Hereinafter, the problems of CSD RFI and limitations of RFID middleware (EPCglobal) will be described.

As shown in FIG. 1, the CSD system guarantees shipping security from the point of arming (POA) to the Intermediate Transit Point (ITP) to the US Trip Terminal Point (TTP). It is a system.

In FIG. 1, a container security device (CSD) is a container security device.

Currently, the meaning of CSD has been expanded from 'Container Security Device' to 'Conveyance Security Device', but it is referred to herein as 'Container Security Device'.

The CSD system includes a CSD reader that delivers CSD information to an operator or a DCP, a reader that delivers CSD information to an operator or a DCP, a data consolidation point (DCP), a data collection server managed by CBP, and a CSD reader. One type includes SHHR (Security Handheld Reader), a hand-held terminal operated by a DHS-designated security agent.

In the conventional CSD system configuration, a reader and a DCP are directly connected to process data, thereby causing a problem in reconstructing and processing massive raw data.

And active RFID tag, which is a structure that requests and responds to commands when most users need it, is different from passive RFID type and structure. Nevertheless, in EPCglobal, there is an unreasonable problem because it is a passive RFID based standard rather than an active RFID based.

If you want to follow the EPCglobal standard, you need to modify or delete a large part of the modules proposed by the EPCglobal standard architecture, such as RP (Reader Protocol) and LLRP (Low Level Reader Protocol).

In addition, Tag and Reader for CSD must go through double encryption for packet security. If you want to apply it to EPCglobal, you should modify the Tag and Reader standard protocol defined by EPCglobal.

In addition, even if the encryption problem is solved, it is easy to add H / W that conforms to the EPCglobal standard for heterogeneous compatibility, while 433MHz has different channel counts, command schemes and protocols, and wakeup time is fixed at 900MHz, while 433MHz is 2.4 seconds ~. It's variable at 4.8 seconds, so you'll need to reimplement all the UI and features that already reflect that.

Therefore, there is a need for a new RFID middleware that can solve these problems and comply with the CSD RFI specification proposed by DHS.
