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: An elevator system controller controls a drive and optionally further elevator components. The controller includes a circuit having a switch to be monitored, the switch having an input and an output, a signal transmitter unit applying an AC voltage input signal to the input of the switch, and a monitoring unit to record an output signal at an output of the switch. On the basis of a comparison of the output signal with the input signal, the circuit generates a monitoring signal that indicates a switching state of the switch. The switch may be, for example, a door switch connected in series with other safety switches to form a safety chain. Applying the AC voltage signal instead of a conventional DC voltage signal makes it possible to avoid electrical corrosion in the switch and also makes it possible to increase a reliability of a detected switching state of the switch.

Abstract: An energy-autonomous elevator system control element includes a piezoelectric layer and processing unit for detecting a control operation, a transmitting unit for wirelessly transmitting at least one signal to a remote elevator system controller, the at least one signal being generated automatically by the elevator system control element on the basis of the control operation, and an energy recovery unit for supplying electrical energy for the elevator system control element. The energy-autonomous elevator system control element can be used as a car operating panel or a landing operating panel in an elevator system.

Abstract: A floor position detection device of an elevator installation, and a method for generating a floor signal, includes a sensor unit and an evaluation unit for generating the floor signal with two states. The states are “in the range of the floor” and “outside the range of the floor”. The sensor unit includes a first Hall effect sensor generating a first floor position characteristic value and a second Hall effect sensor generating a second floor position characteristic value. The evaluation unit generates the floor signal on the basis of a comparison between the first and the second floor position characteristic values. The evaluation unit verifies whether the first and/or second floor position characteristic value is higher than a first threshold value and generates the floor signal on the basis of the result of the verification.

Abstract: An elevator system drive unit moves an elevator car in an elevator shaft to at least two shaft access doors under control of a control unit. The car does not move or moves only to a limited extent if an individual is in the shaft. A monitoring unit and sensor (switching contact) detect changes in state in at least one of the doors using a sequence of pulses monitoring signal. The monitoring unit has a battery and can be switched to an autonomous mode when the elevator system is entirely or partially disabled. The monitoring unit, in the autonomous mode, records state data from the sensor and is connected to a safeguard unit that reads and evaluates the recorded state data, and prevents the elevator system from being put into the normal mode of operation if a change in the state of one of the monitored doors has been detected.

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.
