摘要:
A method and system for remote access to multiple subsystems (102) of an elevator control system (104) are provided. The method includes receiving a request to establish a remote connection at an elevator control subsystem (112) from a remote user system (110). The method also includes determining whether a local connection is established between the elevator control subsystem (112) and service equipment (120). The method further includes establishing the remote connection in response to determining that the local connection is not established between the elevator control subsystem (112) and the service equipment (120). The method additionally includes sending a time since the service equipment (120) was last active and providing an option to complete the remote connection in response to determining that the local connection is established, the elevator control subsystem (112) is operating in a first mode of operation, and a configurable local activity timeout period has not expired.
