摘要： An elevator safety system includes: at least two sensors, each of the sensors being configured for monitoring at least a portion of a hoistway of an elevator system and providing monitoring signals; a transformation unit which is configured for transforming the monitoring signals provided by at least one of the sensors and producing transformed signals corresponding to a common direction of vision; a comparison unit which is configured for comparing the at least two transformed signals and for generating a failure signal if a difference between the at least two transformed signals exceeds a predetermined threshold; and a detection unit, which is configured for detecting a person or undesired item in at least one of the two transformed signals and for generating an alarm signal if a person or undesired item is detected.

摘要： Embodiments as disclosed herein provide a car operation panel for commanding travel of an elevator car from a boarding landing to a destination landing during normal operation of an elevator system. The car operation panel has a plurality of car operation switches to be operated by a passenger from inside of the elevator car during normal operation of the elevator system. The car operation panel is mechanically convertible such as to switch the car operation panel from a first configuration corresponding to the normal operation mode to a second configuration corresponding to an inspection and maintenance operation mode. The car operation panel, when switched to the second configuration, allows manual control of the elevator car to travel in up direction and/or in down direction by operating at least a part of the car operation switches of the car operation panel.

摘要： An exemplary safety circuit includes a plurality of contacts that are configured to establish a conductive path across the contacts when the contacts are in electrically conductive contact with each other. The contacts selectively interrupt the conductive path across them when the contacts are separated. A controller selectively introduces a voltage pulse across the contacts at a voltage level that is effective to overcome an electrical resistance of any contamination on at least one of the contacts. The controller introduces the voltage pulse at least when the contacts are expected to be in contact to establish the conductive path.

摘要： An elevator control system includes a control power supply, a computing core in communication with the control power supply, a communication power supply in communication with the computing core, and a sleep monitor in communication with the control power supply, the computing core, and the communication power supply. The sleep monitor is disposed to selectively turn on/off the control power supply and the computing core, and the sleep monitor is disposed to selectively change an operating state of the communication power supply to a low voltage state.

摘要： A device and method for detecting a misaligned or missing step of a conveyor are disclosed. The missing step detector includes various sensors for detecting the drive speed of the conveyor and for detecting the presence of pallets or steps. The sensor output signals are correlated to determine fixed values characteristic of the specific conveyor in question. Using the fixed values as reference, the missing step detector is able to effectively monitor the conveyor for misaligned or missing steps independent of conveyor speed and time.

摘要： A system for managing elevator power includes a power line connected to a power grid, a motor connected to the power line and configured to receive power from the power line to drive an elevator, an alternative power source connected to the motor, and a power control system configured to control the power line to supply power to the motor to drive the elevator, to detect a predetermined threshold value of power supplied from the power line, and to supply both power from the power line and power from the alternative power source to the motor based on a determination that the predetermined threshold value of power is supplied from the power line.
