摘要:
The invention provides a system and method for handling power outages in a multiple car elevator system in a building having a plurality of floors. The system includes an energy calculator connected to the elevators, and determines a total energy of the elevator system, a total energy required to handle a power outage, a plan to prepare for a power outage and a plan to handle a power outage. The system also includes a movement controller connected to the elevator(s) and the energy calculator. The movement controller receives the plan to prepare and the plan to handle from the energy calculator, and the movement controller executes the plan to prepare if there is no power outage and the movement controller executes the plan to handle if there is a power outage.

The invention is directed to an apparatus and methods for enhancing the energy efficiency of a variable speed drive (VSD) used to control an elevator by disconnecting the VSD from the AC power supply grid when the elevator is idle and reconnecting the VSD when the elevator becomes active. One embodiment of the invention includes an alternating current power supply grid, one or more variable speed drives, contactors connected between the alternating current power supply grid and the variable speed drive(s) that are used to connect or disconnect the variable speed drive(s) from the alternating current power supply grid, and, a control system that controls the contactors. The contactors may include a coil which is powered by the control system to either connect or disconnect the VSDs and the AC power supply grid.

One version of this disclosure includes a system for assigning an elevator car to respond to a call signal wherein a controller is responsible for determining which elevator car will respond to a call signal. This version includes the controller receiving a hall call signal, receiving information regarding the elevator system, determining whether the call assignment can be made in view of a first rule associated with a banned call assignment, and eliminating the rule against banned call assignments when necessary to avoid saturation of the elevator system.

An elevator system comprises at least two independently operable elevator cars in each of a plurality of elevator shafts within a building. The elevator system comprises at least one first elevator shaft having a lower first and a lower second region, where a first elevator car moves within the lower first region of the first elevator shaft and a second elevator car moves within the lower second region. The first and second elevators are moveably controlled independently of each other within the first shaft. The system also includes at least one second elevator shaft having an upper first and an upper second region, where a third elevator car moves within the upper first region of the second elevator shaft and a fourth elevator car moving within the upper second region. The third and fourth elevator cars also are moveably controlled independently of each other.
摘要:
An elevator control system to govern elevator movement to avoid or minimize passenger discomfort caused by pressure changes associated with an elevator's movement and to optimize elevator operation. In one exemplary embodiment, the system uses the passenger's natural relief which occurs while the elevator car is stopped to reduce the pressure difference experienced by the passengers' ears as a factor to optimally control the operation of the elevator. In another example, the system obtains input regarding the traveling speed and conditions of the elevator system. This system then simulates individual trips for passengers that includes monitoring the pressure changes being experienced by passengers throughout the elevator's travels in order to ensure that the pressure differential level for each passenger remains below a designated maximum comfortable and safe level. This system uses the parameters of a successful simulation to govern the actual operation of the elevators.
摘要:
Described is a method for assigning hall calls comprising the steps of receiving a hall call signal, receiving information regarding an elevator system, assigning a destination to the hall call signal, and calculating a call cost value for each elevator car using a handing capacity coefficient. The controller designates the elevator with the lowest call cost value to respond to a call signal. The handling capacity coefficient is a value that reflects the current traffic conditions of an elevator system.
摘要:
A method for assigning an elevator car to respond to a call signal includes a controller that determines which elevator car will respond to the call signal based on certain wait time thresholds. The controller receives a hall call signal, and the controller is programmed with wait time thresholds that can include, e.g., an estimated wait time (EWT), and/or estimated travel time (ETT). In this example, these thresholds are time values above which a passenger is likely to become impatient, either waiting for an elevator car to arrive, or waiting for their elevator car to arrive at its destination. Based on system information an EWT and ETT are calculated and compared to the thresholds. An elevator car is assigned based on this comparison. In some versions, an estimated time to destination (ETD) is used in determining which elevator car to assign. In some versions, a handling capacity coefficient (HCx), which reflects current traffic conditions, is used in determining which elevator car to assign.
