Passenger inf?rmati?n displa? s?stem
is the s?stem t? pr??ide inf?rmati?n ab??t the metr? arri?al t? passengers. A c?mpact
size ?f the same was made ?n PCB. This
pr?ject is the replica ?f the PIDS with a renewable p?wer s??rce. This m?del was
prepared ?sing EMBEDDED s?stem which incl?de s?ftware stim?lati?n and hardware
Firstl? the circ?itr? was designed f?r the same
p?rp?se. A schematic was designed in PR?TE?S ISIS. Circ?it netw?r? was designed
in PR?TE?S ARES.A pdf file ?f the circ?itr? was then generated and with help ?f
it pcb was etched and a netw?r? ?f c?pper wires was f?rmed ?n the pcb. T? place
the c?mp?nents ?f circ?it ?n the pcb h?les were drilled ?sing pcb drilling machine.c?mp?nents
were then placed man?all? acc?rding the schematic. All the c?mp?nents incl?ding
micr?-c?ntr?ller, lcd, led’s, reg?lat?r were s?ldered at their p?siti?n.
Initiall? the m?del was p?wered b?
dc s?ppl? ?sing a dc c?nnect?r. After rem??ing all the err?rs and s?ccessf?ll?
r?nning the m?del, a 20? Ph?t???ltaic cell was inserted in place ?f dc c?nnect?r
al?ng with a 9? batter?. This amendment increased the efficienc?, red?ced the c?st
?f p?wer s?ppl? and pr??ided an ?ninterr?pted p?wer s?ppl? t? micr?c?ntr?ller.
Embedded s?stems are C0MP?TING s?stems with a fer?ent ?perate am?ng
the mechanical and electrical s?stem, ?s?all? beside peri?d c?mp?ting pr?blems.
The? are embedded part ?f an entire de?ice ?s?all? as well as hardware ?r mechanical
c?mp?nent. Embedded s?stems manage se?eral de?ices in ?se n?wada?s.
Embedded s?stems are ?rganized and handled b? a ?nit ?r m?ltiple
pr?cess c?res within the s?rt ?f micr?c?ntr?llers ?r digital signal pr?cess?rs ,
field-pr?grammable gate arra?s, applicati?n-specific integrated circ?its AND
circ?it arra?s. These pr?cess parts are integrated with parts made f?r handling
electrical (and/?r) mechanical interfacing.
An embedded s?stem’s ?e? feat?re is t? specif? the f?ncti?ns that
?s?all? need r?b?st general pr?cess?rs. f?r instance, r??ter and switch s?stems
ar embedded s?stems, whereas a general lapt?p ?ses a c?rrect ?S f?r r??ting p?rp?se.
