hello poh... i need some help, paano iconstruct ang circuit ng queuing machine... yung katulad sa banks...
tnx... saang site ako makakuha ng diagram...?

Electronics and Communication po.. di pa graduate

para san nyo po ba kailangan ito? we do have a queuing system product here

hala uy di ako nagbebenta ah

hehe bawal po ishare eh =) ahmmm teka... ay kala ko MCU-Controlled heheh=)

well basically it is constructed by a asynchronous up/down counter, 555 timer for pulse.. 7447(BCD Decoder) Seven segment..

try to lookup for 79LS192 and how it works.. pede ding 7490 kaso up lang=) tapos puro gates na lang..=)

ilang counters/cashier po ba? then ano ang max number before magloop?=)

mini_mouse ^_^ · « **Reply #6 on:** December 04, 2009, 05:34:17 PM »

mga 3 counters/cashiers lang siguro... hindi naman ngspecify c ma'am basta gagawa lang daw kmi ng queuing machine. ano pins ba and dapat iconnect sa 7447 papunta sa 7490 maliban sa input A,B,C,D? saka ung ibang pin maliban sa output ng 7447 saan icoconnect. hindi kasi ngcount ung 7 segment pgmy decoder sa electronic workbench na software... but f ung 7490-7segment lang, ngcocount xa...

the output of 7490 should be connected to 7447 then seven segment.. hehe =) sorry gagawa sana ko ng simple ckt for this.. unfortunately eh ibang hard disk nakaload sa PC ko ngayon kaya wala kong software na panggawa and even adobe reader for the datasheet.. di ko na kasi kabisado pin outs nyan eh.. =)

alis pa naman ako mya..

hello poh, may diagram na ako sa queueing machine, kaso, ung magcount palang xa... every teller na mgpress ng sarili nilang switch, mg-increment ung counter... the problem is, my other 7 segment display pa na mgdisplay sana ng number ng counter... hindi ko matrap... patulong naman...

what do you mean by "the problem is, my other 7 segment display pa na mgdisplay sana ng number ng counter"?

ano ba max number mo? are you saying that you will use two or more segment for the counter 99 or 999? max digit display?

if you want to have multiple displays here just tap a connection in your displays... and extend a connection for additional buttons=)

sensya ngayon lang ko nakabalik =)

mini_mouse ^_^ · « **Reply #10 on:** December 12, 2009, 10:42:59 AM »

ung 1st 7-segment, mg-count f ano na ang priority, 4 example, max number is 999, bali tagapress ng every counter ng kanilang button, mg-increment ang seven segment... ung 2nd 7-segment at 3rd, idisplay nya f banong counter ang mag-entertain. f counter 1 ung ngpress ng button, mgdisplay ng 1 sa 2nd seven segment, at ung 3rd seven segment, mgdisplay ng 2 if counter 2 will press the button... bali, on-off lang ung 2nd and 3rd seven segment... f cnong counter lang ung priority.. gets mo...? hehehe. ok na sana ung counter lang... ang problem is hindi nag-on off ung 2nd and 3rd seven segment...

just registered to this forum.
Just want to ask kung sino mga local providers nung mga queuing system.
Will use it for 3 tellers/cashiers.

you can email me at les0702@yahoo.com

Tnx

help naman poh, ok na ung circuit ko ng priority number sa queuing machine. kaylangan nlng ng debouncer ckt. para sa switch.. pahingi naman ng diagram ng debouncer ckt.

tnx salink ha.. I had tried many designs na nresearch ko, but hindi parin nagwork... itry ko ung design na nerecommend mo... wait, f gagamitin ko ang RC debouncer, ano ba ang typical values ng maga resistor at capacito na gagamitin ko?

mini_mouse ^_^ · « **Reply #17 on:** January 26, 2010, 09:41:13 AM »

ung ginagamit ko is tack switch, applicable parin ba ung ckt?

coejayson · « **Reply #18 on:** March 12, 2012, 11:07:07 AM »

@mini-mouse : pareho tau ng proj the only difference is that i used 4 tellers, a reset button and a buzzer...00 - 99 po ang increment at may isang 7segment din for the teller number na mag-ientertain...pwd po b share mu ung circuit mu? 8051 sa amin eh,,,373 ung driver ng 7segment namin...

Kaizer03 · « **Reply #19 on:** March 12, 2012, 11:18:53 AM »

^

that will be much more easier using MCU, if you know how to drive a single SevenSegment using the MCU, then the rest will be easy for you..

you will be needing atleast 8inputs for the teller and 2 + 7(or 4 if using bcd decoder).
