A remote monitoring system includes a registration accepting part and a setting part. The registration accepting part accepts registration information. The registration information represents registration of a second user as a child user of a first user being registered in a user management table. A first table associates a browsable monitoring range with each user. When the registration accepting part accepts registration information, the setting part sets a monitoring range which can be browsed by the second user as a child user of the first user to a range not exceeding a browsable monitoring range which is associated with the first user in the user management table.

According to an aspect, there is provided an elevator communication system including a communication bus applying a master-slave protocol, a master node connected to the communication bus and at least one slave node connected to the communication bus. The master node and the at least one slave node are configured to apply, for data communication in the communication bus, a repeating frame structure in which a first time slot of a frame is reserved for the master node and in the remaining time slots of the frame each slave node of the at least one slave node has a dedicated time slot. The master node is configured to extend the time between consecutive frames in order to enable a power saving mode for the communication bus.

A story monitoring method when a robot takes an elevator is provided. The method including: obtaining gravity acceleration of the robot in a static state in an elevator and transient acceleration of the robot in a moving state in the elevator, a starting story number, and a story height of each story; obtaining an acceleration change waveform of the robot; comparing the acceleration change waveform by using an acceleration waveform classifier of the elevator, to obtain a movement status of the elevator at each moment; obtaining actual displacement of the elevator in a complete movement status of the elevator; and obtaining a story that the elevator is on after a complete movement status according to the actual displacement of the elevator, the starting story number, and the story height of each story.

A method for deploying a controller to an elevator system includes generating a request to at least one other controller for obtaining at least one parameter relating to a deployment of the controller to the elevator system, receiving a response, and in response to detection that the at least one parameter in the response comprises a set of operational parameters, initiating a configuration procedure, and in response to detection that the at least one parameter in the response does not comprise the set of operational parameters, deriving an identifier of the elevator system included as the at least one parameter in the response and generating a request including the identifier of the elevator system for obtaining the set of operational parameters. An elevator system is configured to perform the method.
