Abstract

An exemplary elevator system includes a controller that is configured to determine a condition of at least one elevator system component. A message transceiver is coupled with the controller. The message transceiver is configured to send a notification message to a remotely located mobile station that includes an indication of the condition determined by the controller. The message transceiver is configured to receive a response message from the remotely located mobile station that indicates how the controller can address the determined condition.

First claim

I claim:

1. An elevator system, comprising:
a controller configured to determine a condition of at least one elevator system component, the controller classifying the determined condition as one of (i) pertaining to a need for elevator maintenance, (ii) pertaining to a condition in which an elevator is blocked, or (iii) pertaining to a condition in which an elevator is running with disturbance; and
a message transceiver coupled with the controller, the message transceiver being configured as a cellular communication device to utilize a cellular communication service to send a notification message to a remotely located mobile station that includes an indication of the condition determined and classified by the controller without requiring a mechanic to be onsite at the location of the elevator system, the message transceiver being configured to receive a response message from the remotely located mobile station that indicates how the controller can address the determined condition.

2. The elevator system of claim 1 , wherein the message transceiver comprises a cellular communication short message service (SMS) transceiver, the notification message comprises a SMS message and the response message comprises a SMS message.

3. The elevator system of claim 1 , wherein the controller includes a memory including a plurality of predetermined messages and the controller selects one of the predetermined messages as the notification message responsive to the determined condition.

4. The elevator system of claim 3 , wherein
the message transceiver comprises a plurality of inputs;
the controller is coupled to each of the inputs; and
the controller provides an indication on a selected one of the inputs depending on a category of the determined condition.

5. The elevator system of claim 1 , wherein
the controller determines a content of the response message received from the remote mobile station; and
the controller causes a response to the determined condition responsive to the corresponding indication.

6. The elevator system of claim 5 , wherein
the response message includes an indication of one of a plurality of predetermined controller commands.

7. The elevator system of claim 1 , comprising:
a plurality of controllers each configured to determine a condition of at least one elevator system component associated with the controller, each of the controllers being in communication with the message transceiver; and
wherein the message transceiver is configured to send a notification message to a remotely located mobile station that includes an indication of a condition determined by any of the controllers, the message transceiver being configured to receive a response message from the remotely located mobile station that indicates how the corresponding controller can address the determined condition.

8. The elevator system of claim 7 , wherein at least one of the controllers is configured to identify which of the controllers is the intended recipient of a received response message and to communicate with the intended recipient controller regarding the received response message.

9. A method of addressing a condition of an elevator system, comprising the steps of:
using a controller of the elevator system to determine a condition of at least one component of the elevator system;
classifying the determined condition as one of (i) pertaining to a need for elevator maintenance, (ii) pertaining to a condition in which an elevator is blocked, or (iii) pertaining to a condition in which an elevator is running with disturbance;
communicating between the controller and a message transceiver regarding the determined and classified condition;
sending a notification message from the message transceiver utilizing a cellular communication service to a remotely located mobile station without requiring a mechanic to be onsite at the location of the elevator system, the notification message including an indication of the determined condition; and
receiving a response message from the remotely located mobile station that indicates how the controller can address the determined condition.

10. The method of claim 9 , wherein the notification message comprises a cellular communication short message service (SMS) message and the response message comprises a SMS message.

11. The method of claim 9 , wherein the controller includes a memory including a plurality of predetermined messages and the method includes selecting one of the predetermined messages as the notification message responsive to the determined condition.

12. The method of claim 11 , wherein the message transceiver comprises a plurality of inputs and the controller is coupled to each of the inputs;
and wherein the method comprises:
selecting one of the inputs depending on a category of the determined condition; and
providing an indication from the controller on the selected one of the inputs.

13. The method of claim 9 , wherein
the controller determines a content of the response message received from the remote mobile station; and
causes a response to the determined condition responsive to the corresponding indication.

14. The method of claim 9 , comprising:
communicating between the message transceiver and a plurality of elevator controllers;
sending notification messages from the message transceiver on behalf of any of the controllers that determines a condition of an associated elevator component;
receiving response messages at the message transceiver; and
providing a corresponding indication to one of the controllers determined to be an intended recipient of a received response message.

15. The method of claim 9 , comprising communicating the notification and response messages over a wireless link between the message transceiver and the remote mobile station.
