摘要： A human transport device such as an escalator or a moving walkway may include tread elements connected into an endless transport belt, a drive unit for driving the transport belt, and a monitoring apparatus for detecting a faulty arrangement of at least one of the tread elements in the transport belt. The tread elements of the driven transport belt may pass through a transport region and a return region between a first return station and a second return station. The monitoring apparatus may have a detection means and a triggering unit. The detection means may be arranged in a direction of a longitudinal extension of the human transport device below the tread elements of the transport region between the first and second return stations. The detection means may be connected to the triggering unit, and the triggering unit may actuate upon mechanical influence on the detection means.

摘要： A safety system for use in a drive system includes first and second safety sensors that provide respective first and second sensor signals indicative of a safety condition of the drive system. The safety system includes a safety device that processes the first and second sensor signals to determine a safety state of the drive system, and that controls a unit of the drive system based on the safety state. The safety device includes a multi-core processor having first and second processing cores. In some embodiments, the first and second processing cores receive and process the respective first and second sensor signals in parallel to determine the safety state. In other embodiments, each of the first and second processing cores receive both the first and second sensor signals, and each of the first and second processing cores process both the first and second sensor signals to determine the safety state.

摘要： An escalator system includes a pit having an access cover plate, a detector indicating when the access cover plate is open and when it is closed, and a user interface which is located in said pit and which in an active state provides the escalator system with control signals controlling the operation of the escalator and which in a passive state does not affect the operation of the escalator. In order to improve the safety of the escalator system the escalator system is configured to stop movement of the escalator if the detector indicates that the access cover plate is closed while the user interface is in the active state.

摘要： The invention relates to an electronic safety device and a conveyor system comprising the same. The electronic safety device has a safety input for receiving a safety signal, the electronic safety device being configured to terminate its operation responsive to absence of the safety signal in the safety input. The electronic safety device comprises an operation-preventing circuit configured to detect an operational anomaly in the safety input, the operation-preventing circuit comprising a switch adapted to short the safety input when the operational anomaly is present in the safety input.

摘要： The present invention relates to a safe operation-stop method for an escalator for safely operating and stopping an escalator that senses an abnormal speed of the escalator so as to prevent passengers from falling. A safe operation-stop method for an escalator is provided, the method including sensing an abnormal speed of the escalator and stopping the escalator before it is reversely rotated, and being capable of reliable braking when an abnormal speed of the escalator occurs, thereby preventing passengers from falling by adjusting the inertial stopping distance when braking.
