A system for the generation of call advance data for an elevator control, which system is going to be installed in an elevator car moving in an elevator shaft and includes at least one acceleration sensor outputting current acceleration data and/or magnetometer outputting a magnetic flux signal which includes current magnetic flux data at the current position of the elevator car, which acceleration sensor and/or magnetometer is mounted in connection with the elevator car; a velocity calculating unit which calculates from the current acceleration/magnetic flux data current car velocity data; a position calculating unit which calculates from the current acceleration/magnetic flux data and/or from the current car velocity data current car position data; and a call advance processing unit which calculates from the current car velocity data and the current car position data call advance data which designates the time until which the car is able to stop at the next approaching floor in travelling direction, which call advance data is transmitted to a call allocation unit of an elevator control. Call advance data is provided in an easy manner without using existing car position detection devices of an existing elevator to be modernized.

System for the generation of call advance data

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:

Position and load measurement system for an elevator including at least one sensor in the elevator car

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. The elevator calls given by passengers are divided between the modernized subgroup and at least one unmodernized subgroup on the basis of the given selection criterion, and a call addressed to the modernized subgroup is allocated in the new group control to the modernized elevators or a call addressed to the unmodernized subgroup is transmitted via the pushbutton interface to the unmodernized subgroup.
