An elevator is equipped with a plurality of remote monitoring sensors for detecting faults and other events in a variety of components in the elevator. These remote monitoring sensors produce remote monitoring messages having a priority classification according to the fault or monitoring event severity. These remote monitoring messages are processed according to the priority classification and available communication connection properties. Based on the processing the communication connection for transmitting the remote message to a central system is selected and sent or temporarily stored for later transmittal.

The invention relates to a method for controlling a passenger transport system, which transport system comprises at least two passenger conveyors, as e.g. escalators (40, 42) or elevators (36, 38), which transport system comprises a control for the passenger conveyors and for controlling passenger flow in the transport system. The control is connected to a passenger flow determination device (22) for establishing a passenger flow reference value of the actual passenger flow to be expected in the passenger transport system, and which control further comprises a passenger guide system (16) for controlling passenger flow in the transport system, which passenger guide system uses a cost function considering a set of system control parameters as passenger riding time, energy consumption, passenger waiting time, passenger transport capacity, maintenance demand, etc.. The control uses a transport model (12) simulating the function of the hardware components of the transport system under consideration of correlated system operating parameters as e.g. number of active passenger conveyors, passenger conveyor speed, still-stand times, door opening times etc. in connection with passenger flow, whereby the passenger flow reference value is input to the transport model and in an optimization process the system operating parameters are optimized under use of the transport model to meet the passenger flow reference value under consideration of at least one significant system control parameter from said set of system control parameters to achieve a best set of system operating parameters. The best set of system operating parameters is applied to the control of the passenger transport system.

The invention relates to a method for allocating elevators of an elevator group to landing calls given in the elevator group, the elevator group having a control unit having a destination call control, which elevator control unit is connected to determining means for the prevailing traffic condition in the elevator group. Further the control unit comprises at least a first and second operating mode which are selected according to the prevailing traffic condition, wherein the first operating mode uses immediate call allocation of the elevators which includes the display of the allocated elevator on a destination operating panel immediately after having issued a landing call and wherein the second mode comprises the allocation of an elevator to a landing call before the arrival of the allocated elevator call to the landing where the landing call has been issued. The invention allows an adaption of destination control to different traffic situations.
