    Abstract: A monitoring system for people-transporting systems, which systems are in the form of an elevator, escalator or moving walkway, includes at least one interrogation device and at least one safety switch that is connected to the interrogation device via an electrical safety circuit and is used for monitoring an equipment of the people-transporting device. A current direction-dependent unit is arranged in the electrical safety circuit. Furthermore, the interrogation device applies a test voltage with an alternating polarity to the electrical safety circuit. Furthermore, a people-transporting system having such a monitoring system is provided.

    Abstract: A passenger transport system includes a central control unit for controlling system functions, field devices spatially distributed within the system, and a bus system transmitting data between the unit and the devices. The unit and/or the devices detect a current data transmission and the conclusion of the data transmission, and output different types of data telegrams that differ according to urgency. The unit and/or the devices output data telegrams only when no current data transmission is occurring and after a waiting period has elapsed since the conclusion of a previous data transmission. Each type of data telegram is assigned an individual waiting period on the basis of the respective urgency. Thus, a simple transmission prioritization is implemented during the data transmission, wherein each device can transmit data telegrams with different urgency and data telegrams of higher urgency are effectively transmitted with higher priority than data telegrams of lesser urgency.

    Abstract: A passenger transport system includes a bus system transferring data between a central control unit and a plurality of field devices. In a failure detection method, the field devices are configured in an unbranched chain configuration and the control unit transmits a test telegram to a first field device to start a monitoring cycle during which each field device receiving the test telegram forwards the test telegram to a next field device in the chain. During the monitoring cycle, the control unit monitors a communication between the field devices occurring via the bus system, in order to detect when a field device does not forward the test telegram. A data volume transmitted via the bus system during the failure detection method is significantly reduced in comparison to conventional failure tests such that failures can be recognized more quickly and/or simpler hardware and/or software can be used.

    Abstract: A passenger transport installation, e.g. an elevator or stairway, includes at least one drive motor, a conveying device, sensors and an installation controller. The installation controller is connected to at least one local bus node via a status bus, which bus node can receive status signals from an assigned sensor and transmit the same to the installation controller via the status bus to control the passenger transport installation depending on the status signals received. A servicing controller, as a replacement for at least one of the sensors, is connected to the local bus node that is assigned to the replaced sensor or to a centralized bus node for delivering simulated status signals that correspond to the status signals of the replaced sensor in a state that is selectable by the servicing controller.

    Abstract: A method for resetting a safety system of an elevator installation from an actual state, in which a normal operation of the elevator installation is not released, to a desired state, in which a normal operation of the elevator installation is released by the safety system includes the steps of: receiving a reset request, which is transmitted from the elevator control system, for resetting from the actual state to the desired state, in the safety system; carrying out verification of the reset request by the safety system; evaluating the verification by the safety system; and resetting the safety system from the actual state to the desired state if the verification by the safety system is evaluated as valid.

    Abstract: A monitoring device for passenger transport systems, which systems are designed as elevators, escalators or moving walkways, includes at least one detecting device used to detect an external actuation of an equipment of the passenger transport system, a control device and at least one energy store for storing electrical energy. The energy store is kept in a charged state. The energy store is put into a discharged state when the detecting device detects the external activation of the equipment.

    Abstract: A monitoring unit, for monitoring an elevator system, includes a circuit assembly having a power supply unit for dispensing a grid-dependent first operating voltage and at least one processor-controlled monitoring module to actively and/or passively ascertain state data of the elevator system. An energy storage unit, that dispenses a grid-independent second operating voltage, and a first switching device supply the first operating voltage to the monitoring module during a normal operation and supply the second operating voltage to the monitoring module in the event of a power outage. A non-volatile data storage unit that stores a variable operating parameter and a second switching device deactivate parts of the circuit assembly. The monitoring module actuates the second switching device based on the stored operating parameter that has a first value before the monitoring unit is started and has a second value after the monitoring unit is started.
