Abstract

According to an embodiment, a machine operating state monitoring system measures a current flowing through a signal light attached to a machine to be monitored. The machine operating state monitoring system determines an operating state of the signal light on the basis of a measurement result of the current. The machine operating state monitoring system stores in advance a relationship between the operating state of the signal light and the operating state of the machine to be monitored. Furthermore, the machine operating state monitoring system determines an operating state of a machine to be monitored corresponding to the determined operating state of the signal light on the basis of the stored relationship.
