Architecture, design and implementation of IoT devices for monitoring Hilti fastening tool usage.
Fastening tools use a powder cartridge to driving rivets and bolts into concrete and steel. The new IoT devices are added non-invasively to the tools.
This is Hilti's first project in the area of ultra low power technology and IoT. I have been responsible for most technical aspects of the devices from their inception, through prototyping to market release. The three new devices, available with the fixing tools DX5, DX6/460 & DX9, may be observed in Hilti advertisement material on YouTube.
The devices record data from a shock sensor (shock force up to 5000G), tool temperature sensor and ambient temperature sensor, and perform self diagnosis incl. battery voltage monitoring. Data stored during manufacturing to an RFID tag is used for device configuration, A low energy electronic paper display (E-Ink) provides tool usage feedback. Buttons provide access to tool maintenance functions and to Bluetooth activation/deactivation. The devices may be interrogated over Smart Bluetooth (ST Microelectronics BlueNRG/BLE - low energy Bluetooth) using a mobile phone app. They are based on the ST Microelectronics STM32L051 & STM32L071 microprocessors.
Each device is powered by a single non-rechargeable 3V coin cell battery (DX5/DX6) or pair of 3V batteries (DX9), and, with a resting power consumption of 700-2000nA, have a maintenance-free life expectancy of approximately 8-10 years assuming an ambient temperature in the range 0...45°C. The devices however can operate down to -30′C.
Design and implementation of parts of a system for driving power drills into the surface to be drilled.
The system is based on a ST Microelectronics STM32F103 with RTX operating system. My parts of the development included:
- communications protocol over RS485
- power management
- service interface
My role spanned from the early project inception to market delivery.
Development of new features for the ARRI Alexa digital cinema camera
Development & Test of L1 GPRS functionality:
- BCH (Broadcast Channel)
Specification, development & test of subsystems for support of car body control functions:
- Remote Keyless Entry (RKE)
- Passive Start & Entry (PASE),
- Tire Pressure Monitoring (TPM/TireGuard)
Management Experience
