In many business and industrial processes, objects such as production orders, containers, components, machines and finished packaged goods must be securely transported by authorized persons or robots from location A to location B.
Ensuring that this process is successfully executed at the right time, at the right place, along the right route, and by the right person or robot is crucial. It is also important to log all movements for quality, reporting and security purposes.
As many of these processes are carried out indoors where GPS positioning is unavailable, an RTLS (“Real-Time Locating System”) positioning can be implemented using “Ultra-Wideband” (UWB) technology. Due to UWB’s 500 MHz bandwidth it is nearly immune against multipath propagation effects even in harsh industrial environments. UWB radios can operate in the presence of other radio signals, such as those from mobile phones.
Based on the run-time of UWB signals, Dresden-based ZIGPOS has developed an indoor locating system that tracks people and objects in 3 dimensions to within 30 cm. Objects are fitted with a UWB transmitter that is tracked by at least 4 receivers which enables calculation of location based on multilateration. Object identifier and timestamp are also recorded.
To securely verify that the correct person or machine is handling the object, the LEGIC Security Platform has been integrated into the system. The design includes LEGIC’s EAL 5+ certified IoT security module SM-6300 embedded in each ZIGPOS RTLS-enabled object. Leveraging “Root-of-Trust” for secure management of people interacting with things, the RTLS system turns object data and spatial context into secure, actionable information.
Guiding objects to the right destination
When an object needs to be moved, the transporter’s RTLS transponder tag or smartcard is verified via Near-Field Communications (NFC) with the RTLS-enabled object. LEGIC’s technology instantly authenticates the transporter and passes its credentials to the RTLS application, thereby enabling communication about where, when and to what destination the object should be moved.
Once the object detects movement, a visual and/or audio indicator (green/red light and alarm) confirms whether the correct person or machine is transporting the object. Based on Root-of-Trust, LEGIC’s Security Platform enables the secure cloud-management of users and credentials, giving ZIGPOS’ RTLS positioning system the ability to authenticate, track and guide people and robots and their payload to the correct destination.
ZIGPOS’ system includes real-time tracking, access control to enclosed rooms, detection of when objects enter or leave designated areas, micro-navigation to help transporters reach their destination, fall and shock detection, as well as full recording of an objects location history.
LEGIC advant is a cutting-edge transponder technology consisting of ICs for smartcards, key rings, watches, etc. Transponder applets can also be used as "virtualized" chips stored on JAVA cards.
LEGIC security modules are compatible with all common RF standards, NFC and Bluetooth. Their compact design and low energy consumption makes them the perfect choice for wide range of ID solutions.
The LEGIC Security Platform is used in a wide range of application areas requiring automated high-security such as Enterprise access control, Industrial IoT, Mobility and Smart City applications.
