Abstract: The invention relates to a position and load measurement system for an elevator which system is going to be installed in an elevator car to obtain car position data and car load data, which position and load measurement system comprises at least one sensor mounted in the elevator car. The position and load measurement system comprises: a passenger sensor scanning the car interior and/or the car door area; a load signal processing unit connected to the passenger sensor for generating car load data, an acceleration sensor and/or magnetometer, a position signal processing unit connected to the acceleration sensor and/or magnetometer for generating car position data, and a data link for transmitting the output signals of the load signal processing unit and the position signal processing unit to an elevator control unit. The invention provides improved car load and car position data, particularly in connection with an overlay modernization of an existing elevator system.

Abstract: The invention relates to a method for measuring the traffic flow in a building having a people mover system, in which method the following succession of steps is performed: at least two monitoring units with at least one sensor are temporarily installed in the vicinity of entrance- and/or exit area(s) of at least one people mover, each of the monitoring units is provided with a power supply for being operated as an independent unit, events caught by the sensor are associated with the current event time and with the location/position of the corresponding monitoring unit as correlated event/event time/event location data, which correlated event/event time/event location data is used to compute a traffic flow in the building. This data can be advantageously used in the call allocation of a new people mover system of said building.

Abstract: The present invention discloses a method and a system for modernizing at least one elevator group, which comprises a plurality of elevators, a group control that controls the elevator group as well as call-giving appliances connected to the group control via the landing appliance bus. According to the solution a new group control, new call-giving appliances for the floor levels and also a new landing call bus are installed in the elevator group; a new group control is connected to the pushbutton interface of the old call-giving appliances for transmitting calls given by passengers from the new group control to the old group control.

Abstract: The invention relates to a procedure and an apparatus for analyzing elevator functions and detecting deviating functions. By monitoring signals associated with traffic events in the elevator system, an analyzer connected to the elevator learns the normal operation of each elevator independently. Signals occurring during operation are compared with the information thus acquired and a failure alarm is produced or the information is altered to make it accord with the new, changed situation.
