Abstract
Methods and systems for automatically checking an operational status of electrical components of an elevator system, the methods including setting a first power state of all addressed electrical components of the elevator system, measuring a control value power consumption with a power consumption counter, switching a first addressed electrical component into a second power state, monitoring a power consumption associated with the first addressed electrical component, comparing the power consumption associated with the first addressed electrical component with the control value power consumption, and when the power consumption associated with the first addressed electrical component is not greater than the control value power consumption, performing a detected failure operation.
Claims15
A method of automatically checking an operational status of electrical components of an elevator system, the method comprising:
- setting a first power state of all addressed electrical components of the elevator system;
- measuring a control value power consumption with a power consumption counter;
- switching a first addressed electrical component into a second power state;
- monitoring a power consumption associated with the first addressed electrical component;
- comparing the power consumption associated with the first addressed electrical component with the control value power consumption;
- and
- when the power consumption associated with the first addressed electrical component is not greater than the control value power consumption, performing a detected failure operation.
An elevator system comprising:
- an elevator car located within an elevator shaft;
- and
- a controller for automatically checking an operational status of electrical components of the elevator system, the controller configured to execute instructions comprising:
- setting a first power state of all addressed electrical components of the elevator system;
- measuring a control value power consumption with a power consumption counter;
- switching a first addressed electrical component into a second power state;
- monitoring a power consumption associated with the first addressed electrical component;
- comparing the power consumption associated with the first addressed electrical component with the control value power consumption;
- and
- when the power consumption associated with the first addressed electrical component is not greater than the control value power consumption, performing a detected failure operation.
