Abstract

A system and method for adaptive motion sensing with location determination is described. In one embodiment, the adaptive motion sensor is based on vibration sensor readings and can identify different states of motions based on modifiable parameters.

Claims

1-5. -5. (canceled)

6. An adaptive motion sensor system on an asset, comprising:

a vibration sensor; and

a motion detection component that receives input based on readings of said vibration sensor, said motion detection component determining an operating state of said asset through an analysis of said vibration sensor readings relative to a threshold value, said threshold value distinguishing between two operating states of said asset that generate non-zero vibration sensor readings.

7. The system of claim 6, further comprising:

a threshold determining component that receives input values based on readings of said vibration sensor, said threshold determining component said threshold value such that an input on a first side of said threshold value is indicative of a first operating state and an input value on a second side of said threshold value is indicative of a second operating state.

8. The system of claim 7, wherein said threshold determining component match filters a raw histogram.

9. The system of claim 7, wherein parameters of said threshold determining component are configurable using data provided by external communication received by said adaptive motion sensor system.

10. The system of claim 9, wherein said external communication is a satellite communication.

11. The system of claim 6, wherein said vibration sensor is an accelerometer based micro-electro-mechanical system.

12. The system of claim 6, further comprising an analog-to-digital converter coupled to said vibration sensor and a vibration filter that smoothes values produced by said analog-to-digital converter.

13. The system of claim 6, wherein said motion detection component compares received input values to said threshold value.

14. An adaptive motion sensor method, comprising:

determining an operating state of an asset based on an analysis of vibration sensor data relative to a threshold data value located between two peak values on a histogram of said vibration sensor data.

15. The method of claim 14, further comprising match filtering a raw histogram to produce said histogram.

16. The method of claim 14, further comprising generating said vibration sensor data from an accelerometer based micro-electro-mechanical system.

17. The method of claim 14, wherein said determining comprises identifying one of a plurality of operating states that includes an engine on without movement operating state and an engine on with movement operating state.

18. The method of claim 14, further comprising determining said threshold data value using said vibration sensor data.
