RTLS locating system


Now that it is growing, the need to control equipment and people in production plants is increasing. To meet that need, Siemens offers a wireless management solution in the factory with many outstanding advantages:

  • RTLS provides fast location response times.
  • Can transmit in the space of obstacles, not limited by space such as GPS technology, BEIDOU, ...
  • Simple operation system, low cost of inspection and maintenance
  • Capable of developing to monitor each pallet, finished product, etc.
  • Capable of observing through peripheral devices such as Smartphone, Tablet, ...
  • Reduce unnecessary costs of monitoring.
  • Enhance factory automation in the future.
  • High accuracy up to 200cm (on request)
  • Easily scale up monitoring or the number of objects to be monitored. Suitable for monitoring goods, warehouses, moving vehicles within the factory, ...

A product is tracked position during production.

In some countries, the Corona virus is on a positive downward trend, but factories still limit personnel and must adhere to a safe distance between individuals. Thanks to the RTLS locator solution, individuals will be updated with their location or alerted to other employees about a distance violation. This is monitored and recorded to ensure that all employees' activities are observed and the risk of spread is well controlled in the context of the Covid-19 epidemic still in some parts of the world.

 Once the factory is equipped with RTLS technology, this is also the beginning stage for the digitization of production lines. The pallets, packages will be tracked from the time of the finished product to the storage and delivery stage, all controlled by transponders. Helps locate packages accurately and quickly, reducing time spent searching for goods, spare parts and supplies in the warehouse. Contributing to increasing the efficiency of the factory's production process control.

Control the device assembly process with the navigation system

An RTLS system consists of 3 main parts.

  • Information collection includes: Active transponders, anchors/gateways
  • Location server: includes a computer equipped with Locating Manager software used to calculate the real-time position of transponders.
  • IT integration: forward location information to a higher level for easy viewing, development or integration into SAP, ERP systems, etc.

Components in the RTLS system.

Hardware connections are made up of devices such as Anchors, Gateways, which play the role of transmitting signals and receiving information from Transponders and devices mounted directly on the object to be monitored called Transponders. Depending on the needs of each system, the connection and arrangement of Gateway and Anchor are appropriate. In other words, there are two communication layers in the system. The class of mobile devices is equipped with Transponder, the devices in this class can move according to the pre-programmed control (Mobile Production Equipment), the other layer is a real-time location and acquisition system. Signals from the Transponders will be collected by fixed Anchors on a high position above the ground, then will transmit the signal to the Gateways, the tasks of the Gateways will now be synthesized and sent to the routing software. Location at the monitoring room, with positioning software and data analysis from the Gateway, parameters such as the location of the device will be updated and transmitted quickly and accurately.

Gateways/Anchors are fixed with a height above the common ground.

Moreover, if instead of sequentially transmitting data from Transponder to Anchor and then to Gateways, now Gateways can also take on the role of an Anchor and transmit directly to the calculation software, then data can be transmitted to the enterprise's management system such as ERP,.... A special thing about the system is the use of wireless communication, which allows us to limit the connection and easily change So, repair. Currently, we have been implementing RTLS model for a number of factories in many fields such as food, paper, etc.

Transponder is installed on the equipment to be monitored.

Through this, we can see the importance of RTLS in the innovation of production processes and system digitization. Any waste of time for the search and lookup processes will be solved if there is an intervention of the RTLS system. Provide users with a new reliable, flexible, and advanced system. Contributing to promoting the digitization of businesses in the country in particular and around the world in general.
