UCM

Manages Gate overall operation

Contains the Gate Operating

SoftwareUCM is responsible for:-

Initialization of Gate

Mode Management

Validation of media atSMV/SMA

Authorization of passage after

validating media

UCM communicates withSC

UCM operates at 233 M Hz clock

frequency

DOM is of 64 MB

DRAM- 32 MB extendible to 128 MB

NVRAM- 512 KB

PCM

PCM is responsible for passage

managementwith authorization

from UCM

It monitors the passenger

movementthrough 16 pairs of

sensors

Controls the movement of flaps

Controls GED

FLAP ASSEMBLY

Flap assembly consists of MIB,

Motor,Solenoid,LimitSwitch,IPS,

StopperBolt

MIB interfaces all the external

connectors to flap assembly

Motor is ofDCtype operating at 48

V DC

Solenoid moves the flap

Limit switch indicates the latching

of flap arm to solenoid

IPS (Induction Proximity Switch)limits the movement of flap

logically

StopperBolt limits the movement

of flap mechanically

SMA/SMV

SMA/SMV are the media validating

interfaces ofthe gate with

passengersSMV is placed at entry side and

validates bothCSC/CST

SMA is placed at exit sidevalidating CSC/CST and capturing

the CST

SMPS

It generates the DC power requiredby gate modules

It uses switch mode technique for

DC generationIt converts the 230 v AC output of

Gate UPS into 24 V DC

It feeds the 24 V DCto UCM andDispatcher cards which furtherfeeds SMA/SMV

DISPATCHER CARDS

It is a DC-DC converter

It converts 24 V DCto 12 V DC

Located on both free and paid sidesFeeds 24 V to IOTACard and 12 V

to CSCCard and PID

It also acts as interface card forGate audio feeder channel

SENSORS

There are sixteen pairs of opticalsensors located on each gate

These sensors will track the

passenger movementthroughtheisle

16 sensors are divided into 4 zones

Sensors defining the zone willchange depending on the thedirection of passage

POWERFLOW

Operating Voltages Of Various

Modules:-

UCM 24 V DC

PLC 48 V AC

MOTOR 48 V DC

SOLENOID 24 V DC

SMA 24/12 V DC

SMV 12 V DCPID 12 V DC

8/7/2019 3S 02 GATE architecture

Gate will get 230 v AC as its input

Itwill be taken through a MCB

The output of MCBwill be given to

Gate UPSthrough a spike

suppressor

Spike suppressor protects

UPS/Gate against voltage spikes

UPSwill give 230 V uninterruptedpowerto gate

8/7/2019 3S 02 GATE architecture

17/23

UPS outputwill be given to a

terminal block (TB-2)

From TB-2 inputwill be given to

SMPS and PLCtransformer

SMPS converts 230 V AC into 24 VDC and feeds UCM,Free and Paid

dispatchers

Paid dispatcherwill give 24 V DCtoIOTA, and 12 V DCto PID

IOTAwill give 12 V DCto CSC card

8/7/2019 3S 02 GATE architecture

18/23

Free area dispatcherwill give 12 VDCto CSC card and PID

PLCTransformerwill generate four

differentAC voltages and feed PLC

PLCwill convert inputAC into

various DC voltages required for

Motor,Solenoid and Sensors

DATA FLOW

Presentation of media to SMA/SMV

CSC reader reads it

Authorization by UCMPID informs passenger

Validation or errortone from LS

If valid UCM gives command to PLCPLC operates the flap mechanism

8/7/2019 3S 02 GATE architecture

20/23

Tracks the passenger movement

with 16 pairs of sensors

PLC closes the flaps immediately

after passenger clears safety zone

PLC sends passage completion toUCM

UCM records the transaction and

upload itto SC
