Abstract
Signals from a plurality of sensors (vibration sensors, temperature sensors, and humidity sensors) disposed at places on a machine are input through a communication circuit to a numerical controller that controls the machine. The numerical controller uses vibration information, temperature information and humidity information obtained from these sensors to determine whether the machine is in an abnormal state.
Claims4
A numerical controller for controlling a machine, comprising:
- a plurality of sensors disposed at individual places of the machine so as to monitor states at the individual places;
- and
- an abnormality determining unit for determining whether the machine is normal or abnormal from detected information obtained from at least one of the plurality of sensors as well as internal information about the numerical controller;
- wherein whether the machine is normal or abnormal is determined from signals obtained from the plurality of sensors.
