Remote access of an elevator control system with multiple subsystems

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.

1. A method for providing remote access to multiple subsystems (102) of an elevator control system (104) comprising:
receiving a request to establish a remote connection at an elevator control subsystem (112) from a remote user system (110) via a communication unit (106) connected to the elevator control subsystem (112) of the multiple subsystems (102); determining whether a local connection is established between the elevator control subsystem (112) and service equipment (120); 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); and sending a time since the service equipment (120) was last active on the local connection and providing an option to complete the remote connection in response to determining that the local connection is established between the elevator control subsystem (112) and the service equipment (120), the elevator control subsystem (112) is operating in a first mode of operation, and a configurable local activity timeout period for communication between the elevator control subsystem (112) and the service equipment (120) has not expired.
