A moving handrail monitoring system includes a sensor configured to sense at least part of a moving handrail of the passenger conveying device to acquire a data frame; a processing device configured to analyze and process the data frame to monitor whether a tension degree of the moving handrail is in a normal state, wherein the processing device is configured to include: a target object recognition module configured to recognize, based on a sensed movement and/or position and/or color and/or shape, a moving handrail portion that serves as a target object from the data frame; an object feature extraction module configured to extract a tension degree feature of the moving handrail portion; and a judgment module configured to compare the extracted tension degree feature with a system preset interval, and judge whether a current tension degree of the moving handrail is normal.

The present invention relates to step roller monitoring and maintenance personnel monitoring of a passenger conveyor, and belongs to the field of passenger conveyor technologies. In the monitoring system and monitoring method of the present invention, an imaging sensor and/or a depth sensing sensor is used to sense the step roller/maintenance personnel of the passenger conveyor to acquire data frames, and the data frames are analyzed and processed to monitor whether the movement or position of the step roller/activity or position of the maintenance personnel is in a normal state.

The present invention relates to the field of passenger conveyor technologies, and provides an engaging state detection system of a passenger conveyor and a detection method thereof. In the engaging state detection system and detection method of the present invention, a depth sensing sensor is used to sense at least an engaging portion between a step and a comb plate of the passenger conveyor to obtain depth maps, and the depth maps are analyzed by a processing apparatus to detect whether an engaging state between the step and the comb plate is a normal state. The detection of the engaging state includes detection on whether comb teeth of the comb plate are broken, whether engaging teeth of the step are broken, and/or whether a foreign matter exists on an engaging line.

A monitoring system and a monitoring method for a passenger conveying device, and the passenger conveying device. The monitoring system comprises an imaging sensor and/or a depth sensing sensor for sensing a monitoring area of the passenger conveying device to acquire data frames; and a processing device for performing data processing on the data frames to monitor whether the monitoring area is abnormal, and configured to comprise: a background acquisition module for acquiring a background model based on data frames sensed when the monitoring area is in a normal state; a foreground detection module for comparing data frames sensed in real time with the background model to obtain a foreground object; a foreground feature extraction module for extracting a corresponding foreground object markup feature from the foreground object; and a state judgment module for judging whether the foreground object belongs to an abnormal population.

A people conveyor comprises two landing areas located at two opposing ends of the people conveyor; a movable conveying element extending between the two landing areas and configured for conveying passengers between the two landing areas; a handrail extending parallel to the conveying element between the two landing areas and configured for moving with the conveying element; a handrail exit/entry portion located at one of the landing areas and configured for receiving a return portion of the handrail; and a safety switch assembly provided at the handrail exit/entry portion and configured for stopping the handrail when activated. The safety switch assembly comprises at least one sensor surface providing a touch sensor for detecting any part of a human body, in particular a finger, approaching and/or touching at least one of the at least one sensor surfaces.

The invention relates to a truss construction () for a passenger conveyor comprising at least one self-supporting element (). The self-supporting element, which is a roller molded element (), extends in a conveying direction of the passenger conveyor and is formed with at least one rail portion () for guiding step chain rollers () and/or step rollers ().

A moving walkway with a pallet return mechanism is disclosed. The moving walkway generally includes a pallet track having a passenger portion connected to a return portion through an end portion, a plurality of pallets coupled to the pallet track with each pallet extending between front and back ends, and a pallet return apparatus adapted to sequentially lower the front and back ends of the pallet to transition each pallet from the passenger portion to the return portion of the pallet track. Methods for returning the pallet on the pallet track are also disclosed.

A system for detecting a person relative to a passenger conveyor includes a driving circuit for supplying an oscillating drive signal to a first electrode of a capacitive sensor configured to produce an electric field toward a second electrode in response to the oscillating drive signal. A detection circuit is connected to the capacitive sensor, and produces an output as a function of the capacitance of the capacitive sensor, such that the detection circuit senses a change in capacitance of the capacitive sensor, such as when a person enters the electric field between the first and second electrodes. A controller is responsive to the change in capacitance sensed by the detection circuit to selectively adjust an operation mode of the passenger conveyor.

A passenger conveyor includes an endless tread band having a plurality of treads. At least one endless drive chain is driven around a first and a second turn around section by a drive. The drivetrain includes a plurality of links that are associated with drive chain rollers. A plurality of the treads are connected with the drivetrain. At least one panel member is located on a lateral side of the treads. The panel member is moveable with respect to the treads and supported to remain stationary with respect to at least one of the drive chain links. Each of the treads is associated with at least one panel member.

The invention relates to a passenger conveyor, comprising an endless transportation band comprising a plurality of transportation elements, at least one endless transportation chain drivably connected to the transportation band, the transportation chain comprising a plurality of transportation chain links, a plurality of transportation chain rollers, consecutive of the transportation chain links being connected via a respective of the transportation chain rollers, and a plurality of transportation chain roller axles, each of the transportation chain roller axles connecting a respective of the transportation elements to the transportation chain, the transportation elements comprising first transportation elements being supported by a respective transportation chain roller axle, and second transportation elements being supported by a transportation element axle.

A system and method for remotely controlling a passenger conveyor is disclosed. The system and method may include capturing an image of a passenger conveyor and a status changing object with a camera, sending an initiate command from a remote control center to the status changing object, calculating a time delay based on a time the initiate command is sent from the remote control center to a time the image of the status changing object verifies that the status changing object is responding to the initiate command, confirming that no passengers are present on the passenger conveyor and initiating a limited time frame for remote control of the passenger conveyor based on the time delay calculated.

A main drive shaft brake for a passenger conveyor includes a braking element, an actuator, and a counter-actuator. The actuator is de-energized to release the braking element and halt operation of the passenger conveyor during an abnormal or emergency condition. An energized counter-actuator permits release of the braking element but, when de-energized, inhibits release of the braking element by the actuator to prevent unintentional release of the braking element caused by, for example, an accidental loss of power to the actuator.
