An elevator request authorization system for use in a building in which an elevator system services a plurality of floors is provided. The elevator request authorization system includes one or more servers receptive of an elevator request of a user and configured to authenticate the elevator request and to append credential data thereto in accordance with a result of the authentication and an access control system to which the elevator request appended with the credential data is passed from the one or more servers. The access control system is configured to determine which floors of the plurality of floors the user is authorized to visit based on the credential data with an elevator car being assignable to service the elevator request in accordance with a determination result.

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.

Commissioning of a transportation infrastructure peripheral device in a transportation infrastructure control network is disclosed. In the arrangement a peripheral device is attached to a transportation infrastructure control network through a network element or directly to a controller. When the connection has been made, a process for identifying and granting appropriate access rights is initiated. As a result, common network technologies can be used for transmitting information that is critical for elevator operation.

Conventionally, elevator communications have been implemented using travelling cables. This is particularly the case when safety related data transmitted from an elevator car has to fulfil real-time restrictions often set by regulators so that the receiving of the information may not be delayed. Typically, this cannot be guaranteed when wireless transmission technologies are used. The reliability can be increased by using a second to supplement the wireless transmission.

An electronic speed detection system is provided. The electronic speed detection system includes an accelerometer coupled to a moving object and a hybrid altimeter, which includes a first pressure sensor coupled to the moving object and a second pressure sensor. The electronic speed detection system also includes a controller comprising a memory and a processor. The memory storing computer program instructions executable by the processor to cause the electronic speed detection system to determine a normalized position based on first inputs received from the hybrid altimeter, or determine a corrected velocity position based on a second input received from the accelerometer and the normalized position.

Provided is a communication system and a communication method for use in an elevator system, which belong to the field of elevator intelligent control technologies. The communication system of the present invention comprises: a first bluetooth module mounted in an elevator landing area of the elevator system and a second bluetooth module mounted in an elevator car of the elevator system. The communication system and the communication method of the present invention can realize that a passenger completes an elevator calling operation in a completely hand-free mode, which is easy to realize and is low in cost.

A device and a method for controlling an apparatus being an elevator, an escalator or automatic doors are provided, by which it is detected whether a fault is present in the apparatus, it is determined, when the fault is present, whether an automatic fault clearing may be carried out, and if it is determined that the automatic fault clearing may be carried out, the automatic fault clearing is performed by automatically clearing one or more faults.

Radar based systems and methods for gesture recognition to identify hand gestures remotely. A radar unit including a linear array of transmitter antennas and a linear array of receiver antennas monitors objects within a target zone. An image data file is generated by assigning each transmitter-receiver pair of antennas a spatial coordinate, an associated phase value and an associated amplitude value. The image data file is analyzed by a pattern recognition unit to detect assign a gesture state.

In a communication system of a transport system including an elevator, an escalator or a moving walk, a control unit may be configured to control data transmission between at least one uplink communication interface and a plurality of downlink communication interfaces of a networking node. The control unit may be configured to obtain an event necessitating data transmission control between the at least one uplink communication interface and the plurality of downlink communication interfaces. The control unit may be configured to reduce the amount of data transmitted between at least one uplink communication interface and at least one of the plurality of downlink communication interfaces based on the event.

A method for controlling an elevator system comprises receiving media data, receiving at least one of control data and sensor data, transmitting the media data and at least one of the control data and sensor data via a real-time data communication network between a central controller adapted for controlling a drive of the elevator system and a local controller, the local controller being provided in one of an elevator car control panel and a door control panel, wherein the real-time data communication network is adapted for transmitting data packets while ensuring that a data packet is transmitted during a maximal transmission time.
