摘要： A load-cancelling system for conveyance systems, such as elevators, is especially adapted for cancelling the effect of the load weight on power requirements and includes at least one weighing device adapted to determine the weight of the load in the elevator. The system also includes a brake adapted to dissipate energy from the conveyance system and interface means between the weighing device and the brake for translating the result of the weighing operation to a corresponding braking operation.

摘要： A system for controlling the braking force applied to an elevator car driven by an A.C. motor in which means for controlling the cut-off position of the elevator car driving motor from the power supply depending on the load of the elevator car are provided so as to ensure accurate arrival of the elevator car at a desired target floor and a comfortable sense of ride under every condition of the load. The elevator control system is advantageous over prior art systems of this kind in that the capacity of the motor can be reduced and a better sense of ride can be obtained.

摘要： A solid-state static power converter receives a three-phase A.C. input and directly supplies direct current to a D.C. motor armature circuit to operate a traction sheave to control the movement of an elevator car in response to an error signal derived by the selective summation of a speed signal from a tachometer and a vehicle speed command signal. A combined solidstate static power converter receives the three-phase A.C. input and directly supplies direct current to a field circuit of the D.C. motor in response to the operation of a field gating control circuit and also directly supplies direct current to a brake operating solenoid circuit controlling a friction braking element selectively coupled to an output shaft of the D.C. motor. The combined field and brake static power converter includes three controlled rectifying devices and three diodes connected to selectively supply half-wave rectified uni-directional power to the field circuit while a fourth controlled rectifier is connected to one of the phases and cooperates with one or more of the diodes utilized in the field current conversion together with one field output lead to supply uni-directional energy to the brake solenoid. The brake gating control includes a summing circuit receiving an alternating phase reference signal from the source through a lag filter circuit, a disable signal from the source through lead and lag filtering circuits, a constant reference signal, and a brake energy command signal supplied from a second summing circuit. The second summing circuit receives a brake lifting command signal in response to the supervisory control and a brake energy sensed feedback signal.

摘要： A third instruction determination unit determines a current instruction on the basis of a first current instruction determined by a first instruction determination unit (23) and a second current instruction determined by a second instruction determination unit (24). A brake control unit (25) controls a brake device (6) on the basis of the current instruction. The second instruction determination unit (24) determines the second current instruction so that the value of a current indicated by the current instruction determined by the third instruction determination unit increases stepwise when a brake switch (7) ceases to detect that the brake device (6) is in a non-braking state.

摘要： An illustrative example elevator sensor device includes at least one sensor supported on a door of an elevator car. The sensor provides an output including an indication of at least movement of the door along at least one axis and movement of the elevator car along at least one axis. A processor associated with the at least one sensor receives the output and determines at least one characteristic of the movement of the door based on the indication of the movement of the door. The processor also determines a location of the elevator car where the movement of the door occurs based on the indication of movement of the elevator car.
