Abstract: A control system and a control method for controlling the start and stop of multiple passenger conveyors are provided. The control system includes a remote camera for capturing images of the corresponding external state of the passenger conveyor in real time; a remote controller for controlling and collecting the operation state of the passenger conveyor; a monitoring server connected with each remote camera and the remote controller through a data network. The monitoring server uses an artificial intelligence algorithm to analyze images captured by the remote camera to determine whether there are passengers on the passenger conveyor; when the monitoring server determines that there are passengers on the passenger conveyor, the passenger conveyor is grouped into a non-automatic start and stop group; when the monitoring server determines that there are no passengers on the passenger conveyor, the passenger conveyor is grouped into an automatic start and stop group.

Abstract: 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.

Abstract: The embodiments herein provide an automatic non-conveyor stairway comprising two separate straight stair flights that move inside each other without interference. One stair flights moves horizontally. The other stair flight moves vertically. With discrete sequential motion of the stair flights, an arbitrary load is transferred along the stairway. Each stair flights includes several comb-teeth shaped stair steps. The stair steps of horizontal stair flights comprises parallel plates along the stair width attached to a supporting wall at the back. The vertical stair flights include parallel plates fixed at the bottom to a supporting base. The supporting bases are connected to stringer at the left side of the stairs. The supporting walls are fixed to another stringer at the right side. The stringers are confined to move horizontally and vertically, thereby providing the required motion of the stair flights.

Abstract: The present invention provides a handrail entry monitoring system of a passenger conveyor and a monitoring method thereof, and belongs to the field of passenger conveyor technologies. In the handrail entry monitoring system and the monitoring method of the present invention, at least part of a handrail entry region of the passenger conveyor is sensed by using an imaging sensor and/or a depth sensing sensor, to acquire a data frame, and the data frame is analyzed to monitor whether a handrail entry of the operating passenger conveyor is in a normal state or an abnormal state. The monitoring system of the present invention and the monitoring method thereof can timely and effectively detect a danger that a foreign matter is about to be entrapped into the handrail entry, helping prevent foreign matters from being entrapped into the handrail entry, thereby improving safety of the passenger conveyor.
