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.

According to an aspect, there is provided an elevator communication system. The system comprises an ethernet bus, a safety master node communicatively connected to the ethernet bus and configured to communicate via the ethernet bus, and safety slave nodes communicatively connected to the ethernet bus and configured to communicate via the ethernet bus. The safety master node and the safety slave nodes are configured to communicate by using a time-triggered communication protocol. In the time-triggered communication protocol the safety master node is configured to send a polling diagnostic request message to the safety slave nodes by using a predetermined polling cycle.

An elevator communication system includes at least one ethernet bus segment, a controller communicatively connected to the at least one ethernet bus segment, and a plurality of elevator system nodes communicatively connected to the at least one ethernet bus segment. The controller is configured to determine a fault situation in the elevator communication system and cause reduction of the data communication via the at least one ethernet bus segment based on the fault situation.

A tension member for an elevator system includes one or more tension elements extending along a length of the tension member, and one or more a wave guide regions secured to at least one surface of the tension member or integral to the tension member and extending along the length of the tension member. The one or more wave guide regions are configured for transmission of a radio frequency (RF) data signal along the one or more wave guide regions.

A method and an arrangement for commissioning a passenger transportation system includes a mobile device that is computer-controlled from an application and which is configured to exchange data both with a programmable controller controlling the passenger transportation system and with an external database in which configuration information regarding configurations of a plurality of passenger transportation systems is stored. The method steps are: retrieving, from the external database by the computer-controlled mobile device, configuration information that details information regarding a configuration of the passenger transportation system; requesting, by the computer-controlled mobile device under consideration of the configuration information, commissioning information which details information regarding parameters that must be set within the scope of a commissioning of the passenger transportation system; and transmitting the commissioning information to the controller controlling the passenger transportation system. As a result, a commissioning process can be significantly simplified and is less susceptible to faults.

A vertical bounce detection system of an elevator system includes at least one sensor operable to detect vertical movement of an elevator car in a hoistway. The vertical bounce detection system also includes a processing system communicatively coupled to the at least one sensor and a memory system having instructions stored thereon that, when executed by the processing system, cause the vertical bounce detection system to determine a bounce energy level of the elevator car based on sensor data from the at least one sensor. The instructions further cause the vertical bounce detection system to compare the bounce energy level to a bounce condition threshold. A speed reduction of the elevator car is commanded to continue movement of the elevator car at a reduced speed based on determining that the bounce energy level exceeds the bounce condition threshold.
