A method of controlling segregation of transportation infrastructure control data within a shared data network is disclosed. According to the disclosed method, the data network used for carrying the transportation infrastructure control network may be shared with devices that are not contributing to the elevator functionality. This is achieved using a particular arrangement that allows the use of generic peripheral devices in a transportation infrastructure network without disturbing elevator operations.

An arrangement for connecting transportation infrastructure peripheral devices, such as elevator and escalator peripheral devices, to a transportation infrastructure devices, such as elevator, using a building network is disclosed. In the arrangement a virtually dedicated channel for communication between elevator and escalator peripheral devices is created. The channel is used for transmitting signals, such as elevator calls, so that there is no need to use a dedicated and separated network for elevator and escalator peripheral devices.

A commissioning arrangement for elevator and escalator network devices is disclosed. When the elevator network devices are connected to the elevator network they first get a unique communication address from another network element that is typically a network switch located higher in the chain of network switches. Then, using the established communication address, the network element contacts an automatic commissioning service for acquiring network configuration settings.

An elevator monitoring system for monitoring an elevator system includes a wireless mesh network. The wireless mesh network includes a first group of node devices including a plurality of first node devices configured to be constantly on, a second group of node devices comprising a plurality of second node devices, and a control node device. At least one of the plurality of second node devices belonging to the second group of node devices is configured to relay elevator related monitoring data from at least one other second node device belonging to the second group of node devices, when the second group of node devices are on. The control node device is configured to control the second group of node devices to turn on and to enter the sleep state on demand. A method for monitoring an elevator system and an elevator system are also disclosed.

An emergency operation controller for an elevator is connected to other emergency operation controllers of their respective elevators through network, and each controller constitutes a node in the network. The controller generates and transmits an emergency condition detection message to other controllers in the network which constitute adjacent nodes to the controller when the controller detects an emergency condition, and receives an emergency condition detection message from other controllers which constitute adjacent nodes to the controller in the network when other controllers detect an emergency condition. The emergency condition detection message includes a propagation count. The propagation count is configured to be decremented by one, each time one controller transmits the emergency condition detection message to other controllers which constitute next adjacent nodes. The emergency condition detection message is continuously transmitted until the propagation count reaches to zero.

An elevator request authorization system is provided and includes a second server configured to grant an elevator use token upon request from a first server registerable with the second server for establishing secure communications between the second server and the first server. The first server is configured to be receptive of an elevator request relating to elevator usage by a user, to authenticate the user, to authorize the elevator usage by the user to which the elevator request relates, to request the elevator use token from the second server via the secure communications upon authentication and authorization and to deliver the elevator use token to the user upon receipt.

Disclosed is an elevator system having an elevator including a controller, wherein the controller is configured to communicate over a plurality of networks with a plurality of devices, the plurality of networks including a first network and a second network and the plurality of devices including a first device and a second device, the first device being within or proximate the elevator, wherein the plurality of devices are configured to communicate over a third network, and wherein, while the plurality of devices are communicating over the third network, the controller selectively effects a communications bridge over the plurality of networks between the plurality of devices and supersedes the communication over the third network.

A Bluetooth wireless communication system and method for communication in an elevator hoistway, and belongs to the technical field of elevators. The Bluetooth wireless communication system of the present invention comprises: a first Bluetooth module, a second Bluetooth module, and one or more diffusion Bluetooth modules disposed in the elevator hoistway; wherein the first Bluetooth module, the second Bluetooth module and the diffusion Bluetooth modules are networked to form a Bluetooth MESH network such that data transmission between the first Bluetooth module and the second Bluetooth module is performed via at least one of the diffusion Bluetooth modules.

Acquisition of position information of an elevator car. The system for acquiring the position information of an elevator car of the invention comprises: a first Bluetooth module travelling in an up-down direction of an elevator hoistway following the elevator car, and a second Bluetooth module disposed in the elevator hoistway; wherein the second Bluetooth module broadcasts a Bluetooth signal containing an identifier of the second Bluetooth module to the elevator hoistway, and the first Bluetooth module senses signal strength information of the Bluetooth signal it receives and determines the identifier corresponding to the second Bluetooth module broadcasting the received Bluetooth signal; the system is configured to determine the position information of the elevator car according to received signal strength information of the Bluetooth signal and a corresponding identifier.

A method to communicate with a passenger in a car within a transportation system includes receiving an alarm signal from the car, and initiating a text communication session via a communication system associated with the car in response to the alarm signal.
