Abstract: Example embodiments relate to a method and a system for integrating electric elements of an elevator in a single module, e.g. in the door operator of the elevator, to reduce the number of components to be installed and to enable the electric elements of the elevator to be added to the door operator on the elevator car already at the manufacturing stage. The method may include intergrating electric components to be placed in the elevator, such as location elements, acceleration sensors and door zone sensors, with the door operator or some other module already at the manufacturing stage of the elevator, e.g. by placing the active parts of the sensors in conjunction with the door operator and the passive parts on the floor level side.

Abstract: A safety system for supervising safety of an elevator may include a safety space in an elevator shaft, elevator buffers in the elevator shaft, or both; measuring means for continuous measurement of absolute position of an elevator car; and a safety device. If the safety system includes the safety space, its size may be reduced. If the safety system includes the elevator buffers, their size may be reduced. The safety device may be adapted to receive data about the absolute position of the elevator car; calculate a velocity of the elevator car at each instant of time using the absolute position; monitor the calculated velocity in order to ensure that the calculated velocity remains within an allowed motion limit curve; and control at least one stopping device for stopping uncontrolled motion of the elevator car if the calculated velocity exceeds the allowed motion limit curve.

Abstract: An equipment (21) for controlling an elevator door (22) comprises a motor (24), an encoder (25) connected to the motor and a motor control unit (26), which are integrated into a coherent motor unit (23), an elevator control system (28), power supply means (29) for supplying operating power from the control system to the motor unit, and a data transfer bus (30) for data transfer between the control system and the motor unit. According to the invention, the data transfer bus (30) is bi-directional, and the motor unit (23) comprises a motor data storage unit (31).

Abstract: The invention concerns a method and a system for integrating electric elements of an elevator in a single module, e.g. in the door operator of the elevator. Especially to reduce the number of components to be installed and to enable the electric elements of the elevator system to be added to the door operator on the elevator car already at the manufacturing stage. The basic idea of the method of the invention is to integrate electric components to be placed in the elevator system, such as location elements, acceleration sensors and door zone sensors, with the door operator or some other module already at the manufacturing stage of the elevator, e.g. by placing the active parts of the sensors in conjunction with the door operator and the passive parts on the floor level side.

Abstract: The invention concerns a device, a method and a system for improving the safety system of an elevator. The safety system of the invention comprises an electric safety device, which monitors the velocity and position of the elevator in the elevator shaft. The safety device is e.g. a computer that is able to stop the elevator, using the brake of the hoisting machine or an optional car brake. The basic idea of the safety system of the invention is to form a continuous limit curve for control of elevator speed. The limit curve defines the limits of allowed elevator motion, which are determined on the basis of the nominal speed of the elevator and the location of the car.
