The bracelet is always located thanks to a marker system situated in the plant, that triangulate its position. This way, if there’s an evacuation, it can control who has left the plant and who hasn’t.
Other security system is the gas detector. It works with a device placed in the chest of the operator, and when there’s a leak it communicates with the bracelet, which will send out a warning to the control center. It has also an emergency button, that connects, as well, with the control center.
smart safety sensor
It is place in the gas detector. When there are harmful gases, the detector whistle and vibrate, the smart safety sensor detects the situation and sends a signal directly to the closer marker. This marker sends the information to the cloud and it is redirect to the central control panel. This way, a local detector is turned into an online one.
HOW IT WORKS
How it works
How we did it
We’ve developed the hardware, the firmware and the mechanical of the security bracelet, the smart safety sensor and the marker. They were developed following ATEX normative, that was managed by Accent Systems.
Connectivity: Bluetooth Low Energy (BLE), Ultra Wide Band (UWB), NFC.
Battery: AA/2 lithium battery (bracelet and smart safety sensor), AA lithium battery (marker).
Others: tricolor led, accelerometer (bracelet and smart safety sensor), vibrator (bracelet), microphone (smart safety sensor).
STEP BY STEP
Tecnalia contacted to ask for a presonalized beacon with ATEX certification. But once they explained us their idea, we acted as a consultant to focus the development of the project to the right direction. Finally it wasn’t a beacon project, but three projects in one to achive the highest security in refineries.
After this first step, we started developing the hardware and the firmware of the security bracelet and the basic mechanics to start the testing in the refinery.
2. MECHANICAL DESIGN
Once we had the results of the first testing in the refinery, we enhance the design of the hardware and firmare, and created the definitive mechanical of the security bracelet.
Here it is:
3. SENSOR CASE AND MARKER DESIGN
The first device was developed and approved, and all the testing done. Then. we started designing all the technology of the smart safety sensor and the marker: hardware, firmware and design.
When these 3 devices were developed, the complete smart human safe system was tested in refinery.
