Abstract
A current collector monitoring system in one aspect of the present disclosure is provided with: a collected current measurement unit; a collected current state determination unit; an image acquisition unit; an event recognition unit; an event determination unit; and a determination result output unit. When a state of collected current corresponds to an abnormal state, the image acquisition unit acquires an image including, within an angle of view, a collector shoe provided to a current collector.
Claims14
A current collector monitoring system comprising:
- a collected current measurement unit configured to measure a collected current collected by a current collector;
- a collected current state determination unit configured to determine whether a state of the collected current corresponds to a preset abnormal state;
- an image acquisition unit configured to acquire an image including a collector shoe provided in the current collector within an angle of view when the state of the collected current corresponds to the abnormal state;
- an event recognition unit configured to recognize an event related to the collector shoe in the image;
- an event determination unit configured to determine whether the event corresponds to a preset abnormal event;
- and
- a determination result output unit configured to output a signal containing a result of determination made by the event determination unit.
A current collector monitoring system comprising:
- a vibration measurement unit configured to measure vibration of a collector shoe provided in a current collector;
- a vibration state determination unit configured to determine whether a state of the vibration corresponds to a preset abnormal state;
- an image acquisition unit configured to acquire an image including the collector shoe within an angle of view when the state of the vibration corresponds to the abnormal state;
- an event recognition unit configured to recognize an event related to the collector shoe in the image;
- an event determination unit configured to determine whether the event corresponds to a preset abnormal event;
- and
- a determination result output unit configured to output a signal containing a result of determination made by the event determination unit.
