摘要： A tension member tension monitoring arrangement and method for measuring tension member tension of elevator tension members of a bundle of tension members, the elevator comprising an elevator car suspended by the tension members, such as ropes or belts, of the bundle of tension members, a termination at one end of a tension member and a mounting plate for attaching the termination relative to the hoistway, counterweight and/or the elevator. The tension member tension monitoring arrangement comprises at least one capacitive pressure sensor arranged in connection with a tension member termination. The arrangement further comprises a control unit connected to the at least one sensor. The at least one sensor is configured to sense the tension member forces of the tension members of the bundle of tension members attached to the tension member termination and generate a signal relating to one or more tension members of the tension member bundle readable and/or measurable by the control unit and proportional to the sensed load or force.

摘要： A method and device are disclosed for remotely monitoring an escalator. The method includes capturing an image of an escalator by means of a camera, wherein each step of the escalator is provided with a pattern of a predetermined color, the color of the pattern is different from the color of the step of the escalator; graying the captured image; covering the background of the grayed image, and separating the pattern; identifying the outline of the pattern; and comparing the identified pattern outline with a pre-stored pattern outline, and on the basis of the comparison result, determining whether the pattern on each step of the escalator is obstructed, wherein the pre-stored pattern outline is a non-obstructed pattern outline.

摘要： The invention relates to an elevator apparatus, comprising: a shaft, an elevator car vertically movable in the shaft, one or more ropes connected with the car, and a controller for controlling movement of the car. In order to detect sway in one or more elevator ropes connected with the car, the apparatus comprises at least one sensor unit arranged in the elevator shaft to detect sway and to produce a control signal indicating to the controller the detected sway. The controller compares the detected sway to a predetermined limit and prevents movement of the elevator car when sway reaches the predetermined limit.

摘要： An elevator drive apparatus is described which includes a drive unit for driving an elevator car, a brake device for braking a motion of the elevator car, a detector for detecting an electrical operation amount of the drive unit, and a controller. The controller is configured to release the brake device, to compare the detected electrical operation amount with a threshold, and to apply the brake device when the detected electrical operation amount exceeds the threshold. In this way, it is ensured that a speed of the elevator car in case of a rescue situation is within a safety limit.

摘要： An elevator includes an elevator motor; a motor drive for the elevator motor having a frequency converter including a rectifier bridge, an inverter bridge and a DC link in between, which frequency converter is controlled via a controller, the rectifier bridge being connected to AC mains via three feed lines including chokes, and the rectifier bridge being realised via controllable semiconductor switches; a contactor being located between the feed lines and AC mains; and a backup power supply at least for emergency drive operation. An emergency control is associated with the motor drive, which emergency control is configured to perform an automatic emergency drive. The emergency control is connected to a manual drive circuit having a manual drive switch for a manual rescue drive. The elevator includes a motion sensor connected to the emergency control, whereby the emergency control is configured to activate a brake and/or gripping device of the elevator in case the car speed during a manual rescue drive exceeds a predetermined threshold value.

摘要： A method of monitors a climate quality within a building having an elevator running between floors of an elevator hoistway. The elevator car of the elevator includes at least an air-quality sensor. The method is characterized in that a fan of the elevator car is running when the door(s) of the car is/are opening at a floor station to suck air from the building's floor level into the elevator car to the vicinity of the air-quality sensor and sensing the air-quality by the sensor preceding to generating data of the air-quality.
