Abstract
A diagnostic display system for indicating the status of elevator system operating conditions develops signals representing each operating condition and detects when a car is delayed in responding to a request for service. Signals representing each operating condition are stored when a delayed car response is detected so that the status of the operating conditions as they were at the time of delayed car response can be displayed at a later time.
Claims16
In an elevator system in which one or more elevator cars respond to requests for service wherein the status of one or more of a plurality of operating conditions of the elevator system may delay car response, a diagnostic display system for indicating the status of the elevator system operating conditions, comprising:
- means for developing signals representing each operating condition;
- means responsive to the developing means for detecting a delay of car response;
- means responsive to the detecting means for storing the signals representing each operating condition when a delayed car response is detected;
- and
- means coupled to the storing means for indicating the status of the operating conditions as they were at the time of a delayed car response.
A diagnostic display system for indicating the status of elevator system operating conditions wherein one or more elevator cars of a group respond to requests for service, comprising:
- first means for displaying the status of elevator operating conditions in a particular format on the display as the elevator system is operating;
- means for detecting delay events each of which occurs when a car is delayed in responding to a request for service;
- means responsive to the detecting means for storing data representing the current status of elevator system operating conditions each time a car is delayed in responding to a request for service wherein the operating conditions relate to operation of each car individually and to operation of the cars as a group;
- means coupled to the storing means for retrieving stored data representing the status of elevator operating conditions as such conditions were at the time of a selected delay event;
- and
- second means coupled to the retrieving means for displaying the status of the elevator operating conditions represented by the retrieved data in the particular format.
