KHI: a radio vibration sensor for railways: greatly simplifying the wiring of equipment

Kawasaki Heavy Industries: Wireless vibration sensor

Newly developed radio vibration sensor for railway vehicles.

This makes it easy to add and install railcar vibration sensors.

Conventional: Wired vibration sensor

In the past, wired vibration sensors were installed in railway vehicles.

Wired vibration sensors monitor railway vehicles, such as monitoring the health of trolleys and tracks.

This time: Wireless vibration sensor

This time, the vibration sensor was made wireless.

Traditionally, equipment wiring, which is essential for wired sensors, is greatly simplified.

Troubles such as design work, wiring work, noise and disconnection are reduced.

In addition, the battery life of about 4 years has been achieved by reducing power consumption during communication and adopting low power consumption components.

Overview of wireless vibration sensor:

Measurement items: acceleration, temperature

Wireless system: BLE 4.2 (Blue Tooth Low-Energy)

Power supply: Primary battery

Lifespan: About 4 years (during actual operation)

Output: 100Hz (low data) / 1kHz (frequency component)
