Overview

This reference design is inspired by the need to monitor the health of motors and machines to accurately predict and schedule maintenance (or replacement) while minimizing cost and downtime during industrial production. Millions of industrial motors are monitored today with handheld or wired piezo accelerometer sensing devices. Recent advancements in ultra-low-power processing technologies, radios, and piezo sensor miniaturization have enabled the development and deployment of low-cost, small motor monitors with wireless capabilities. These wireless motor monitors are powered by coin cells that have a battery life of more than 10 years. These systems provide the same broadband sensitivity as existing handheld systems, collect vibrational data and perform spectral analyses on that data. This integrated intelligence lets you deploy and monitor these systems in difficult-to-reach locations. The wireless motor-monitoring reference design uses two different, yet electrically equivalent, form factors for development and testing.

These form factors include:

  • Modular form factor
  • Compact form factor

In the modular form factor, TI LaunchPad™ development kits and EM connectors allow you to incorporate multiple radios and processors with energy-management and sensor subsystems. The compact form factor uses the MSP430™FR5969 ultra-low-power microcontroller unit (MCU) with a CC2650 BLE radio, but can be connected to multiple sensor boards. The standard sensor board supports a PCB piezotronic vibration sensor.

The 30-pin expansion connector on the small form factor board enables the base-board to be operated with the MCU, the CC2650 radio, or both. The system software assumes you are using both devices.

This reference design focuses on the compact form factor system.
