SICK LOCU2 Tag Based Localization UWB Anchors
Product Information
The product is called LOCU and it is a tag-based localization system that uses UWB anchors. It comes with hardware components that are necessary for the system to work. The product is designed to be installed, operated, used, and maintained by trained, authorized specialists. It is important to follow the instructions and safety guidelines provided in the user manual to ensure error-free and safe operation. The product comes with a warranty which may be voided if the device housing is opened by unauthorized personnel. The product must be cleaned with a soft, dry or slightly moistened cloth and should not be opened as it does not contain any user-serviceable parts.
Intended use
SICK LOCU components constitute the UWB (ultra-wideband) hardware part of
SICK’s localization system solution. The SICK LOCU hardware is well suited for
precise indoor tracking of tagged objects of various kinds. LOCU hardware
comprises LOCU1xx tags, which are mounted on the assets to be tracked and
infrastructure-mounted LOCU2xx antennas, called anchors. LOCU tags can be
localized in all areas covered by a set of LOCU anchors.
SICK LOCU hardware is a part of complete solution, SICK offers a comprehensive
portfolio of services for LOC systems, from consulting to support. SICK RTLS
(real-time locating system) solutions LOC facilitate full transparency of your
supply chain processes by creating a digital twin of your assets – in your
factory, warehouse and beyond. Key use cases include automation and
optimization of processes in logistics and production, from manual to fully
automated processes. With LOC, SICK provides a system solution which
integrates several localization technologies and further sensors into a
software platform, called Asset Analytics, which acts as middleware.
About this document
This Quickstart document describes the how-to setup LOCU hardware
components.Before starting to work with LOCU, read this Quickstart document
carefully and make sure that you are familiar with the device. The information
on the correct and safe operation of the system presented here will help you
avoid personal injury or damage to property. You can also obtain support from
your sales partner.
For your safety
It is essential that LOCU units are transported, stored, installed and used in accordance with its intended use in order to ensure error-free, safe operation. LOCU hardware can only be installed, operated, used and maintained by appropriately trained, authorized specialist personnel. Specialist personnel are individuals who possess the technical training, knowledge and experience necessary in order to understand the tasks entrusted to them, evaluate these and identify possible hazards.
Precautions:
- Do not use deformed or damaged product or battery.
- Do not expose the devices to extreme heat, pressure or humidity.
- Do not charge or use the product if liquid has entered.
- Do not use or store the devices in dusty or dirty areas.
- Protect the product from excessive moisture.
- Do not expose the devices to water, rain, splashing water or spilled drinks.
- Do not spray anything on and inside the device.
- Dropping, knocking, violently shaking and any rough handling may damage the device.
- Do not transport or store flammable gas, liquid or explosives in the vehicle compartment where the device is installed.
- In case of malfunction, contact your sales partner.
- Do not modify the product.
CAUTION LOCU hardware do not contain any user-serviceable parts and are not allowed to be opened by unauthorized personnel! Opening the screws of the device housing will invalidate any warranty claims against SICK AG. For further warranty provisions, see the General Terms and Conditions of SICK AG.
WARNING
Limit human exposure to electromagnetic fields. During operation, the human
exposure regulations covered by IEC/EN 62311 must be observed. Suitable safety
distances must be maintained during both short-term and long-term work in the
radiation range of the antennas. The minimum distance to be maintained between
the device and the human body during long-term transmission is 20 cm.
NOTE: Performance of anchors might be affected by materials like metal or
water in the vicinity of the anchor, shielding or absorbing signals.
Maintenance and cleaning
- Maintenance LOCU hardware do not contain any user-serviceable parts.
- Cleaning Clean the housing with a soft, dry or slightly moistened cloth. Do not use any solvents or high-pressure cleaners
Installation and commissioning
Scope of delivery
Every anchor package consists of:
- Anchor LOCU (different device models available)
- Additional accessories depending on anchor model:
- RJ45 Feed-through lock connector is included only with LOCU212-503
- External, non-detachable, UWB antenna and Cable Gland are included only with LOCU200-003
CAUTION Do not remove the antenna from LOCU200-003. LOCU200-003 should
only be used with the original provided antenna.
NOTE: Anchors are sensitive to RF electromagnetic fields in the ranges
950±20 MHz and 1900±50 MHz. Performance can be affected on exposure of anchor.
To avoid that, it’s recommended that minimum distance to DECT base station is
2 m and a minimum distance to UHF RFID readers is 1 m.
Only use shielded cables (CAT6 or higher) that are grounded properly. Maximum
cable length is 100 m for PoE from anchor to PoE switch.
NOTE: Anchors needs to be connected to a physically separated network,
separate VLAN or firewall protected network, due to security reasons and also
to get the best performance and have easier management. High traffic due to
the localization system could cause issues / slow down the network if the
anchors are in the same network as other critical infrastructure.
Power supply options
-
Power over Ethernet
Connect anchor to network switch supporting PoE IEEE 802.3af standard with Ethernet CAT6 cable. Once the anchor is connected to a stable power supply, a blue LED blinks several times that indicates the anchor was turned ON. Then LED is turned OFF. -
DC 48 V, Passive PoE
Anchor can be also powered from single or multiple port PoE injector with DC 48V output. Power supply is injected and delivered into unused Ethernet pairs (Pairs 4,5 positive terminal and 7,8 negative terminal).
NOTE: Always use galvanic isolated 48V power adaptor with short circuit
protection for passive PoE injection. Never connect “Power+Data” injector
ports to the computer or other network devices.
NOTE: For connecting LOCU212-503 anchor, use RJ45 Feed-through lock
connector (see Figure 3.). Support part is not needed if the RJ45 connector
has strain relief. It is not possible to use RJ45 Feed-through lock connector
with a RJ45 connector which has latch protection.
CAUTION To ensure IP65 rating, fasten the Cable Gland/Feed-through lock
connector properly using only human force. Overtightening can lead to damage
of cable gland and/or anchor housing.
Mounting
To get the best anchor performance it is recommended to deploy all anchors to
the same height in a given localization area and anchor position in the area
should follow square geometry with distance between each anchor from 5-15 m.
The ratio between the two sides of the square should not be higher than 3:1.
If possible, always maintain a direct Line of Sight between the tag and the
anchors. For narrow corridors zig-zag positioning is an option. This can be
very useful in narrow corridors, for example in large warehouses. Be aware
that this deployment decreases precision in the Y axis, so use this option as
a last resort:
Anchors are typically deployed at the height 3 – 6 meters above the floor.
Recommended mounting is with LOCU2 bracket available at SICK as an accessory
set including four machine screws for fixing the anchor to the bracket (P/N:
2130302).
Mount LOCU200-003 with the antenna pointing upwards in order to get maximum
possible performance. Do not bend/fold the antenna.
NOTE: Keep a distance from anchor to any walls or metal parts of at least
15 cm in all directions to avoid significant degradation of performance.
