RadioSafe - Global Safety Stop Series

• Laser scanners provide individual safety to single machines or single operators, at the local level.
• RadioSafe provides global safety features to a complete infrastructure and whole workforce. 

• A sum of safe components does not make a safe solution especially with radio signals: safety cannot be only passive.
• RadioSafe performs permanent surveillance of the transmitter safety signal, and it reacts within a few milliseconds. 

• When the navigation system shuts down, one does not have the option to choose when, where, and how to stop, which leaves one blind.
• RadioSafe enables you to safely draw “stop patterns” such as “access and emergency evacuation routes.” 

• Highly productive applications should always anticipate how to resume normal operations, even during emergencies.
• Thanks to RadioSafe, a track of all AGVs exact locations might be recorded, at all times, to organize a quick fleet restart. 

• Navigation systems rely on highly evolutive software (constant navigation optimizations) and hardware (scalable fleets)
• A distinct software/hardware safety solution guarantees safety assessment integrity throughout upgrade operations. 

Yes, it is possible. Depending on the RadioSafe transmitter type, up to 10 distinct inputs can be activated and sent to the RadioSafe receivers. 

Yes. For example, let’s consider a fleet of 6 shuttles. The first 6 inputs of the RadioSafe transmitter might be used to address a specific shuttle number for any of 4 commands. 

Definitely! RadioSafe contains many embedded functions that might be used without any type of PLC. However, without a PLC, there would be only 4 programmable outputs available. A PLC expands these possibilities. 

The serial link of the RadioSafe receiver gives access to all variables and status of the receiver, including all setting parameters. 

A PLC connected to each RadioSafe receiver’s serial link and centralized communication to all PLCs will provide centralized control. 

Yes. With a safety PLC connected to the RadioSafe receiver, it is possible to monitor RadioSafe safety status or safety outputs and further activate/deactivate safety supervision only under certain location or environment conditions controlled by the safety PLC.  

If the zones can be defined safely, one specific RadioSafe transmitter can be installed in each zone.  Each RadioSafe transmitter will emit on a different radio channel. For the mobile robot carrying the RadioSafe receiver to switch from one zone to another, a channel change procedure can be executed to match the RadioSafe transmitter of the zone to be reached. 

• No. RadioSafe has its own radio infrastructure (both frequency and transmission protocol) to guarantee proper radio propagation.
• Wi-Fi infrastructures tend to be quite loaded, and consequently, they do not guarantee signal transmission everywhere. 

• No. As of today, RadioSafe is only available on 433/434 MHz and 911/918 MHz bands with EU/FCC/IC approvals.
• 2.4 GHz has some limitations for non-stop signal transmission in addition to longer and more complex radio frames. 

• Yes. RadioSafe solutions are delivered with one transmitter and optional standard components if signal propagation needs to be further boosted.
• It is mandatory to provide a preliminary layout of the application to choose the appropriate optional components. 

• Yes. First, all setting parameters are easily accessible on site to adjust them to the application’s real constraints.
• Secondly, additional radio propagation components can be added further to a live mapping of RadioSafe’s Received Signal Strength Indicator – RSSI.  

• Yes. A dedicated time setting is available for any signal loss, and a distinct time setting is triggered for a safety stop. This means that short harmless interruptions will be allowed while longer safety-critical ones will stop the fleet of mobile robots.
• Individual machine passive and active stops are clearly identified separately on RadioSafe receiver’s serial link or outputs.
