AltSql Vector Live Demo

A vibration sensor sits on a motor. Every 1.6 seconds the device turns what it hears into a fingerprint, looks for the closest one it was taught, and names the state, or flags a pattern it does not know. You can teach it on the spot.

Simulated motor, real engines. The motor, its faults and the sensor are simulated. AltSql Core and AltSql Vector run in this page, compiled to WebAssembly.

How to Run It

1. Teach it the healthy motor. Idle, running and loaded, six fingerprints each.
2. Give the bearing a fault. Running, bearing wear at 60%: it has never heard this.
3. Name the new pattern. Teach it as bearing wear, and it is known from then on.
4. Let a new bearing wear out. Forget the fault, start from a healthy bearing, and watch.

On a wide screen the demo has more room: open it full screen.

About AltSql Vector

AltSql Vector lets a device learn what a machine sounds like. It turns each stretch of vibration into a 32-byte fingerprint, names what it hears by the closest fingerprint it was taught, and flags what it was never taught. Taught only a normal bearing, the Alpha flagged every fault fingerprint in nine fault recordings of a public bearing data set, at each of two loads, and none of 55 normal ones; with so few normal ones, a false-alarm rate of a few percent cannot be ruled out.

AltSql Vector is a prototype, all rights reserved. It works and is tested on a PC, in simulation and on recorded vibration, and it has not yet run on a microcontroller: that is the Beta. Its Alpha report sets out how it was built and tested, and how each figure was measured or computed. Device makers and investors can ask for it through the contact page.
