Description

Patronage display system in elevator
The application is application number: 201310648583.4, the applying date: 2013-12-03, invention and created name: the divisional application of the application for a patent for invention of patronage display system in elevator.
Technical field
The present invention relates to a kind of counting assembly, particularly relate to patronage display system in elevator.
Background technology
One chip microcomputer technology develops rapidly, and the counting equipment developed based on singlechip technology and product are widely applied to every field.Product auto-counter of today adopts cordless mostly, have developed the dedicated test chip of Multiple Type already.And utilize AT89C51 to be control unit, be aided with the counting assembly of multiple peripheral hardware collocation and become the trend of present Auto-counting application.But be not applied in elevator demographics.
Same floor is provided with multi-section elevator, and when wanting to take elevator and elevator when there being passenger not at this layer, the elevator taken because passenger is uncertain is which seat (there is elevator completely situation), may press the up-downgoing call button of all elevators simultaneously.
Elevator is in up process, when if certain floor has a up call signal, (signal must be called out before elevator arrives this layer, if elevator had run this floor, then on elevator, once respond this signal in up process), when then arriving this floor, elevator stops, eliminate this layer of upward signal, corresponding upward signal lamp goes out, and elevator door is automatically opened and allowed passenger enter ascending for elevator simultaneously.In ascending for elevator process, the downlink call signal in entrance hall is inoperative.When elevator is in descending process, if when certain floor has a downlink call signal, then arrive this floor elevator and stop, eliminating this layer of downgoing signal, corresponding downgoing signal lamp goes out, and elevator door opens that to allow passenger enter elevator descending automatically simultaneously.In the descending process of elevator, the up call signal in entrance hall is inoperative.Elevator in upstream or downstream process, through the floor of noncall signal, and in car not this floor signal time, elevator does not stop door not opening yet.When ascending for elevator, elevator Priority Service is in up layer selection signal.When elevator is descending, elevator Priority Service is in descending layer selection signal.When elevator is parked in certain layer, eliminate the layer selection signal of this layer.
After passenger presses the up-downgoing call button of different elevator simultaneously, first arrives this layer (or first meet take condition) and meets when elevator (elevator less than) that passenger takes condition arrives this layer and stop, and passenger takes this ascending for elevator or descending.Still can stop after being arrived this layer by other elevators that passenger presses up-downgoing call button, now stop does not have passenger, other passengers in elevator need to control elevator door and close continuation operation, both resource is wasted like this, also be delayed the wait time of elevator, reduce the delivery efficiency of elevator.
