Remote controller linkage to an elevator system
First Claim
1. An elevator system responsive to remote control operations comprising:
- a data transmission network including at least one serial communication bus;
a plurality of function control units, connected to said serial communication bus, for locally performing distinct elevator functions; and
at least one receiver means for receiving remote messages originating from a remote controller and transmitting through said at least one serial communication bus a control message including at least one first control command and the bus address of the receiver means which transmitted the control message;
a controller connected to said at least one communication bus for receiving control messages from said receiver means and determining whether action requested by a received control message must be performed by said controller, and if so, then issuing a second control command;
at least one of said function control units receiving the control messages and, if the action requested by the control message is relevant to the function of a particular function control unit, then the particular function control unit directly performs the requested action.

Abstract
A remote controller linkage is established to an elevator system having one or more elevators and using a data transmission network (21) comprising at least one serial communication bus for the transmission of control signals between the operating and/or other devices belonging to the system, car calls, landing calls and other information obtained from and/or generated by the devices included in the elevator system. At least one of the serial communication buses belonging to the data transmission network (21) of the elevator system is connected to a functional unit (3,7,10,13) fitted to receive messages sent to it by a remote controller (1,22). On the basis of the message received, the functional unit (3,7,10,13) transmits into the serial communication bus a message containing at least one control, call or other datum and the bus address of the transmitting functional unit (3,7,10,13).

10. A method of servicing an elevator system comprising the steps of:
-
(a) sending a message, including a request-for-information part and an authorization part, to a transceiver by remote control from a service computer, the message being sent immediately upon entering a building where the elevator system is located; (b) retransmitting the message from the transceiver through a communications bus to a controller; (c) determining if the request reflected by the request-for-information part of said message is permitted on the basis of said authorization part of said message; (d) gathering appropriate information responsive to the request if it is determined in step (c) that the request is permitted; and (e) sending a second message, including the gathered information, to the service computer through the communications bus and the transceiver as a function of the determination of step (c) and the action of step (d). - View Dependent Claims (11, 12, 18, 19, 20, 21)

17. An elevator system responsive to remote control operations comprising:
-
a data transmission network including at least one serial communication bus; at least one receiver means for receiving remote messages originating from a remote controller and for transmitting through said at least one serial communication bus a control message including at least one control command and at least one identifier, the identifier identifying the remote controller or the receiver means which transmitted the control message; at least one function control unit, connected to said serial communication bus, for performing distinct elevator functions, said at least one function control unit responding differently to received control messages based upon the control command and the at least one identifier and a current status of the elevator system; and a controller, connected to said at least one communication bus, for receiving control messages from said receiver means and determining whether action requested by a received control message requires action by said controller, and if so, then acting on the requested action. - View Dependent Claims (22)
