Description
The application is application number：201310648583.4, the applying date：2013-12-03, invention and created name：Multiply in elevator
Guest's digital display shows the divisional application of the application for a patent for invention of system.
Technical field
The present invention relates to a kind of counting device, more particularly in elevator, patronage shows system.
Background technology
One chip microcomputer technology is developed rapidly, the counting equipment developed based on singlechip technology and product extensive use
To every field.Product auto-counter of today uses cordless mostly, and the special of Multiple Type is have developed already
Detection chip.And be control unit using AT89C51, be aided with the counting device of a variety of peripheral hardware collocation as present
The automatic trend for counting application field.But it is not applied in elevator demographics.
Same floor is provided with multi-section elevator, when there is passenger to want to take elevator and elevator not at this layer, due to passenger not
It is determined that the elevator that can be taken is which seat (exists elevator expire situation), may press simultaneously the up-downgoing callings of all elevators by
Button.
Elevator during up, if certain floor have during up call signal (signal must be reached in elevator the layer it
Preceding calling, if elevator had run the floor, the signal is responded during elevator is next time up), Ze Daogai buildings
Elevator stops during layer, eliminates this layer of upward signal, corresponding upward signal lamp goes out, and allows passenger to enter while elevator door is automatically opened up
Ascending for elevator.During ascending for elevator, the downlink call signal in entrance hall does not work.When elevator is during descending, if
When certain floor has downlink call signal, then stop to the floor elevator, eliminate this layer of downstream signal, corresponding downstream signal lamp
Go out, make passenger descending into elevator while elevator door is automatically opened up.During elevator is descending, the up call signal in entrance hall is not
Work.Elevator is during upstream or downstream, when not having the floor signal by the floor of noncall signal, and in car,
Elevator does not stop door and not opened yet.In ascending for elevator, elevator Priority Service is in up layer selection signal.When elevator is descending, electricity
Terraced Priority Service is in descending layer selection signal.When elevator is parked in certain layer, the layer selection signal of this layer is eliminated.
After passenger presses the up-downgoing call button of different elevators simultaneously, first reaches this layer (or first full
Foot takes condition) and meet passenger and take when the elevator (elevator less than) of condition reaches this layer and stop, passenger is taken on the elevator
It is capable or descending.And other elevators for having pressed up-downgoing call button by passenger are reached and can still stopped after this layer, now stop
Without passenger, other passengers in elevator need control elevator door closing to continue to run with, and so both waste resource, also postpone
The stand-by period of elevator, reduce the delivery efficiency of elevator.
The content of the invention
To solve the above problems, aobvious the invention provides patronage in a kind of elevator based on infrared signal transmission circuit
Show system, can monitor and count in real time patronage in lift car, using the system, elevator can be improved to a certain extent
Delivery efficiency, save the delivery time of elevator resources and passenger.
The following technical scheme of present invention sampling：
Patronage shows that system, including infrared signal transmission circuit, heat release infrared sensor, microprocessor in a kind of elevator
Device, display module and power supply module；
Described infrared signal transmission circuit includes branch road 1, the branch road 2 in parallel with branch road 1, distinguished with branch road 1 and branch road 2
Branch road 3 and voltage comparator in parallel；Described branch road 1 is the series arm of infrarede emitting diode and resistance R3, described
Branch road 2 is the branch road that infrared receiving terminal is connected with resistance R4, and described branch road 3 is the branch road that resistance R1 connects with R2；In branch road 2
Infrared receiving terminal and resistance R4 connection end extraction wire be connected to electricity in the positive input of voltage comparator, branch road 3
Resistance R1 and resistance R2 connection end extraction wire is connected to the negative input of voltage comparator；
Described infrared signal transmission circuit has two groups, and one group is used to add counting, one group of use to entering the passenger in car
Subtract the infrarede emitting diode in counting, every group of circuit in the passenger to going out car to be mounted opposite with infrared receiving terminal, infrared hair
The infrared ray of optical diode transmitting can be received by infrared receiving diode；
Further, described voltage comparator is any one in LM324, LM358, uA741, OP27.
Described infrared signal transmission circuit is connected with microprocessor, by the voltage comparator in infrared signal transmission circuit
Output signal input into microprocessor；
Described heat, which releases infrared sensor, to be used to detect human body temperature signal, judges whether still someone waits seating to the floor
Elevator；Heat is released infrared sensor and is connected with microprocessor；
Further, described microprocessor is single-chip microcomputer.
Described display module is connected with microprocessor, and the data to be displayed after processing is delivered to display mould by microprocessor
Block, shows the number in current lift car；
Further, described display module is any one in LCD, LED.
Described power supply module is used for feed system power supply.
Beneficial effect：
The present invention counts the quantity of passenger in elevator using Emission and receiving of infrared device, and information is exported to display immediately
Module, to be supplied to the quantity of passenger loading in the passenger lift for waiting elevator, when there is the selectable elevator of multi-section, Cheng Keke
Elevator ride fewer in number is selected according to prompt message, is easy to passenger's reasonable arrangement to take the plan of elevator；
The present invention is also provided with heat and releases infrared sensor to detect the presence signal of passenger, if having passenger by pectus electricity
After the elevator that ladder and seating are wherein first reached leaves, heat releases the presence signal that infrared sensor can't detect passenger, can be by the building
The call signal of layer is released before elevator is not reached, and elevator no longer stops when running to this floor, is easy to elevator resources reasonable
Utilize；
Based on above-mentioned technical proposal, the present invention is solved because the elevator running state information of passenger's acquisition is few and is waiting electricity
The elevator that all still can be stopped and caused after expired with multi-section carriage lift demand caused by elevator call buttons is pressed when terraced
The wasting of resources, the problem of carriage lift efficiency reduction；The delivery efficiency of elevator to a certain extent, can be improved using the present invention,
Save elevator resources and the delivery time of passenger.
