Problem in thesis..GSM module and analyzing SMS

[louis26]

Gud day poh senio...asking 4 help lang poh..naaprove poh thesis nmn..kelangan poh nmn ng microcontroller that can analyze SMS..nu poh b maiisuggest niong microcontroller ska possible poh bang maanalyze ng gsm module ung sms without opening manually the message...sna poh matulungan nio kme....


THANK YOU VERY MUCH FOR YOUR HELP!!!!

What kind of analysis?
Can you elaborate more.

How can the analysis be done without reading/opening the message?
The message must be retrieve first, parsed to analyze the contents.

If you only need the sender, date/time sent, message center number, data coding, protocol id, etc. , the PDU sms format can give you these information. 
This is set by sending AT+CMGF=0 then reading the text message.
The sms format sent by the GSM module will now be PDU.

our system is composed of 4 outlets and a panel...we need to turn on and turn off this outlet1,outlet2,outlet3,outlet4 using sms and a confirmation message will be sent into the registered number if the access is successful or not ...our problem are the ff:
a)what particular microprocessor we will use?
b)is different GSM module has different features?then which GSM module is fit for our system?

if you have ideas about our system please share it with us.. THANK YOU.....

A PIC16F876 could be used as a controller.
For the GSM module, i think the one from egizmo is commonly used.
Other components are also needed, such as triac or relays to control the outlets.
You must decided/plan the maximum power per outlet. From this you can decide the parts to be used.

For the features, AT commands are used to send and receive SMS which is pretty much standard.

Another gotcha, is that working with AC power, glitches and EMI are common and causes havoc on your MCU.
Proper grounding and PCB design should be considered on this project. 
Turning ON and OFF at AC zero crossing helps a lot also.

Nagets ko na poh..thank you very much...pro ndi poh kme ganun klaki background sa pgconstruct ng circuit using those components kaya i think we need some tutorial sa net pra maintindihan nmn kung panu nmn g2mitin those components..THANKS A LOT poh..pde nb aqng mgbigay ng pogi points??newbie here.. BTW kung g2mit poh b kame ng nokia phones as alternative, AT commands p din poh b gamit nun??

[marcelino]

BTW kung g2mit poh b kame ng nokia phones as alternative, AT commands p din poh b gamit nun??

exactly!!!

search for such manual over the net.

[louis26]

Thank you poh....sna ala kmeng mgng problema sa programming khit 1st tym nmn...hehe marung nmn kme ng c++ kea lng ndi pa sa microcontroller.. GUD LUCK SMEN...hehe THANX..

[louis26]

kung lalagyan q poh b ng 10 seconds power on delay ung circuit n2 pra poh maprotect xa sa too much high current sa time ng pgon ng power nia??mk2tulong poh b un or khit ndi qn xa lgyan kc preho lng..?

[rdpzycho]

'yung Power On Delay ay useful lang kung laging may brownout at tuloy tuloy ang pagpatay sindi. whether ngayon mo isindi or 10 seconds later parehas lang ang surge current, ang gamit lang ng delay is kung namatay ang kuryente tapos within one second sumindi, 'di masisira ang ibang equipments.

@louis26, please be reminded that TEXTSPEAK is discourage in this forum.

@sir marcelino
Sorry poh..newbie here kasi eh..hehe
@rdpzycho
ganun poh ba..kasi may circuit breaker kame n gagamitin before pumasok sa circuit namen ung electricity kaya inisip ko pagopen ng breaker mataas ung current na papasok sa circuit namen kaya ko naisip pero pgiisipan q p din ung sinabi mo..tnx..

[louis26]

tanong ko poh tungkol sa GSM module...kung gagamit poh ba kami ng GSM module mas madadalian poh ba kame sa programming nun kesa sa mga nokia phones??or simply san poh b kame madadalian sa programming ng module sa GSM module or sa nokia fones kasi poh ala talaga kameng background sa AT Commands eh..??

[Co0LëT♥]

pareho lang... ang kaibahan lang pwede direct connection sa GSM using resistors unlike nokia kailangan mo pa ng level converter. tsaka mahal ang gsm kumpara sa 6210... hirap nga lang maghanap ng 6210 

[SpongeBob]

3310 at 3315 marami pa mabibili

[louis26]

pwede poh bang gamitin ung 3310 para sa application nmen..supported b niya yung mga features n kelangan nmen sa project namen??
 

[Co0LëT♥]

fbus protocol ang 3310... madugo yon he he he

[SpongeBob]

pwede pero FBUS protocol ang gamit nyan sa interfacing

mas madali ang 6210 ( AT commands) pero mahirap maghanap.

[louis26]

can somebody give us a list of phones supports AT Commands so that we know what else aside from nokia 6210 we need to find if we cannot find 6210 phones..thanks..!

[zer0w1ng]

Old nokia phones only.
Some old ericssons also supports serial AT commands.

Another option is using bluetooth connectivity.
Also using AT commands. Works in most newer phones.

may naisip akong ibang option kaya lang mahal...pero at least "modern" ehehehe.

USB HSDPA modem + USB Host MCU (Vinculum)

less than 1k nalang ang modems ngayon (Smartbro, tattoo) tapos $24.50 (2.5k?) yung MCU. so less than 5k pa din yun (e-gizmo gsm module). at least yung dalawang components ay pwedeng gamitin for other functions, di lang bilang GSM Module.
