Pre/Post-Paid	Smart	Metering	System	for	S&CC	Victor	O.	Ma:hews	and	Emmanuel	O.	AdeAba	Covenant	University,	Ota,	Nigeria	Contact	email:	smartcu@covenantuniversity.edu.ng	IntroducAon	This	is	a	new	concept	in	electricity	meter	billing	based	on	GSM	SMS	network.	The	system	when	deployed	will	automate	the	gathering	and	tracking	of	data	about	electricity	usage	in	Nigeria.	Every	month,	thousands	of	meter	readers	drive	from	home	to	home	to	manually	read	millions	of	electricity	meters	a@er	which	the	collected	data	is	entered	into	billing	systems,	most	o@en	by	workers	reading	the	logbooks.	This	veritable	army	of	meter	readers	keeps	the	uAlity	company	ﬁnancially	alive,	it	involves	a	lot	of	ﬁnancial	overhead.	We	have	designed	and	produced	a	prototype	of	a	new	generaAon	of		electricity		meter		which		promises		to		fully		automate	intelligently	the	data	gathering,	tracking,	transmission	and	billing	and	payment	technique	of	any	electricity	subscriber.	Based	on	a	microcontroller	rather	than	spinning	disk,	this	new	generaAon	meter	uses	wireless	network	plaForm	to	transfer	informaAon	from	the	subscriber’s	residence	to	a	centralized	server	at	the	electricity	oﬃce	for	billing	processing	and	onward	bill	noAﬁcaAon	to	user’s	GSM	Handset	as	well	as	the	meter	LCD	display.	Conclusion	• 	The	pre/postpaid	electricity	meter	is	designed	to	be	used	on	the	 SMS	 plaForm	 to	 send	 and	 receive	 billing/metering	informaAon	at	the	subscriber’s	end		• When	money	is	paid,	the	ﬁnancial	houses	send	informaAon	to	the	 central	 database,	 which	 in	 turn	 sends	 informaAon	 to	 the	respecAve	 meter	 and	 authenAcates	 its	 ability	 to	 conAnue	working	 without	 delay,	 otherwise	 the	 system	 will	 disconnect	the	subscriber	from	the	main	line.	• Patent	Pending	NIST	Global	Ci>es	Teams	Challenge	Expo,	13th	–	15th	June	2016,	Aus>n	TX,	USA	Figure	1.	Block	diagram	of	Smart	Metering	and	Billing	Beneﬁts	•  Reduced	data	collecAon	costs:	Economy	of	electric	power	billing	by	the	operators	due	to	minimal	human	intervenAon	in	reading	of	meters.	•  Accurate	and	immediate	billing	informaAon	in	real-Ame.	•  Instant	tamper	detecAon	report	•  Billing	through	a	low	cost	GSM	data	&	SMS	text	messages	•  Fast	and	easy	installaAon	at	user’s	residence.	•  Billing	of	users	without	power	consumpAon	will	be	completely	eliminated	since	meter	reading	is	automated.	FuncAonality	•  Meter	informaAon	is	read	from	the	electricity	company	at	the	branch	oﬃce	through	signals	using	the	GSM	SMS	network	for	a	postpaid	billing	system.	With	a	prepaid	plan,	the	subscriber	purchases	a	special	electricity	company	GSM	based	scratch	card	with	various	monetary	amount	and	send	informaAon	to	an	assigned	number	for	authenAcaAon	purposes	of	the	said	meter.	The	system	is	designed	to	give	alarm	when	the	subscribers	electricity	unit	is	down	to	a	parAcular	unit,	also	it	can	alert	the	company	when	an	aYempt	is	made	to	tamper	with	the	meter	connecAon.	Prepaid	planners	will	just	load	with	appropriate	amount	of	money	according	to	there	usage	capability.	Figure	2.	The	Developed	Prototype
