摘要： A passenger moving installation includes a plurality of tread elements forming an endless conveyor belt, wherein the tread elements are at least partially covered by at least one element that limits a transportation height of a user set of the installation. A safety system is configured to detect a risk of collision between the user set and the covering element. A method of determining a risk of collision between a user set and at least one covering element in a passenger moving installation at least partially covered by the covering element, includes determining the height of the user set in a monitoring area via a safety system, comparing the height of the user set to the height of a safety threshold, and triggering an event in the safety system if the user height exceeds the safety threshold.

摘要： A monitored escalator barricade system is disclosed herein having a barricade assembly including a hosting column supporting a one-way swinging door and a magnetic locking mechanism. The barricade assembly is installable at a landing floor and allows for one-way passage of a user riding along an outer edge of an escalator in order to prevent injuries. The barricade assembly utilizes IR beam transmitters on an exterior of the hosting column to detect when a user arrives near the landing floor and unlock the one-way swinging door as the user approaches. The monitored escalator barricade system includes various visual and audio indicators for notifying authorities.

摘要： A method for controlling a passenger conveyor, which passenger conveyor includes an endless band of conveying elements, the endless band including an inclined conveying section; a drive shaft arranged to drive the endless band of conveying elements when rotated; a motor for rotating the drive shaft; a first sensing arrangement for sensing a rotation speed of the motor; a brake activatable to act directly on the drive shaft or an element fixedly connected to it for stopping rotation of the drive shaft; and a control system. The method includes rotating the drive shaft with the motor; and sensing rotation speed of the motor with the first sensing arrangement. The passenger conveyor includes a second sensing arrangement for sensing rotation speed of the drive shaft, and the method includes sensing rotation speed of the drive shaft with the second sensing arrangement; detecting deviation between the rotation speed of the motor and the rotation speed of the drive shaft or a multifold thereof; and activating the brake for stopping rotation of the drive shaft if deviation, in particular deviation meeting predefined criteria, is detected between the rotation speed of the motor and the rotation speed of the drive shaft or a multifold thereof, wherein said multifold equals to the rotation speed of the drive shaft multiplied with a preset factor n, wherein n preferably equals to transmission ratio between the drive shaft and the motor. A passenger conveyor implementing the method is also disclosed.

摘要： A safety monitoring device monitoring safety-related states in a passenger conveyor system has first and second double contact relays each controlled by a control voltage to switch first and second normally open contacts and a feedback contact synchronously between an open and closed relay states. First and second controllers each determine properties of the system correlated with safety-related states and in dependence generate the control voltages. The controllers and two double contact relays form first and second safety monitoring switch arrangements for monitoring first and second safety-related states and correspondingly switch first and second switching states within a safety monitoring chain of the system. The first arrangement includes the first contact of the first connected in series with the first contact of the second relay. The second arrangement includes the second contact of the first relay connected in parallel with the second contact of the second relay.

摘要： The chain stretch detection device is configured to detect a stretch of a chain in a power transmission device. The power transmission device includes: a driving sprocket; a driven sprocket; and a chain, which is wound around the driving sprocket and the driven sprocket, and is configured to transmit power of the driving sprocket to the driven sprocket. The chain stretch detection device includes: a meshing height measurement device configured to measure meshing heights of the chain in a range in which the driven sprocket meshes with and the chain; and a signal processing device configured to determine a height difference between adjacent rollers in the chain through use of signals acquired by the meshing height measurement device and estimate an amount of the stretch of the chain based on the determined height difference.
