EQUIPMENT MONITORING SYSTEM
First Claim
1. An equipment monitoring system comprising:
- a monitoring unit; and
a plurality of sensors onboard the equipment, the sensors arranged to measure a plurality of operational variables for the equipment in use and the monitoring unit arranged to receive operational variable measurements output from the sensors,wherein the monitoring unit is arranged to determine a current value of a sensor characteristic for each sensor and to compare the current sensor characteristic value with a predetermined sensor characteristic value in order to determine automatically whether a change of one or more sensors has occurred between instances of operation.

Abstract
The invention concerns an asset monitoring system (10) having a monitoring unit 8 and a plurality of sensors (4) onboard the asset. The sensors (4) are arranged to measure a plurality of operational variables for the asset in use and the monitoring unit (8) is arranged to receive operational variable measurements output from the sensors. The monitoring unit is also arranged to determine a current value of a sensor characteristic (ZA1; ZB1) for each sensor and to compare the current sensor characteristic value with a predetermined sensor characteristic value in order to determine automatically whether a change of one or more sensors has occurred between instances of operation.

14. An equipment monitoring method comprising, for each instance of operation:
-
receiving at an equipment monitoring unit operational variable measurements output from a plurality of sensors onboard the equipment in use; obtaining a current value of an sensor characteristic for each sensor; and comparing the current sensor characteristic value with a predetermined sensor characteristic value in order to determine automatically within the equipment monitoring unit whether a change of one or more sensors has occurred between instances of operation of the equipment.

15. A data carrier comprising machine readable instructions for control of an equipment monitoring unit to:
-
receive operational variable measurements output from a plurality of sensors during use of the equipment; obtain a current value of an sensor characteristic for each sensor; and compare the current sensor characteristic value with a predetermined sensor characteristic value in order to determine whether a change of one or more sensors has occurred between instances of operation of the equipment.
