摘要:
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.

摘要:
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.

摘要:
A conveyor system has a plurality of sensors coupled to a computer system, the computer system being programmed to check a number of safety functions greater than the number of sensors. A method of controlling the safety function of the conveyor comprises providing signals from a plurality of sensors disposed in relation to the conveyor to a computer system; operating the conveyor in a learn mode; during operation in the learn mode determining in the computer system the relationship between the sensor output signals and pre-stored logic in the computer system which describes the physical geometry of the possible conveyor types and permissible operating characteristics thereof and determining the relationship between the sensor output signals to establish the safety integrity of the sensors, and storing sensor signal patterns as a reference pattern; and subsequently operating the conveyor in a run mode in which safety functions are monitored; and during the run mode comparing in the computer system the pattern of sensor signals with the reference pattern and with the pre-stored logic so as to establish the safety integrity of the sensors, of the computer system and of the operation of the conveyor.
摘要:
The invention relates to a truss construction (2) for a passenger conveyor comprising at least one self-supporting element (4, 16). The self-supporting element, which is a roller molded element (4, 16), extends in a conveying direction of the passenger conveyor and is formed with at least one rail portion (6, 8) for guiding step chain rollers (7a) and/or step rollers (7b).
摘要:
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.
