Statement of Project Task

PRESENTED BY: Tsokoh Frank Gbesimi

To develop a LabVIEW-interfaced smart meter with load

control/monitoring GUI. This smart meter can be

accessed by client remotely either using an active

IVRS(Interractive Voice Response Service) from the

server end with a mere phone call or using a mobile GUI

or a PC GUI over a GPRS/GSM network.

Design Requirements

Switch ON/OFF devices remotely from a LabView/Mobile GUI or using an

IVR service from a phone call.

to acquire the device status of all house apliances remotely from a

LabView/Mobile GUI or using an IVR service from a phone call.

to acquire the amount of voltage and load remotely from a LabView/Mobile

GUI or using an IVR service from a phone call.

To acquire the instantaneous energy status remotely via a LabView/Mobile

GUI or using an IVR service from a phone call.

To acquire the energy consumption history remotely

To Top-Up the smart meter from a LabView/Mobile GUI or using an IVRS.

Three ATMEL Controllers were used for this project. One for the IVR server ,

two for the smart meter itself , a GPRS module(SIM900) was used for the

wireless communication , ADC0808 module with 8 analogue input channels was

used for analogue data acquisition, ACS 712 current/voltage sensor was used to

sense current across load , DTMF decoder for the IVR service and some other

sequential logic components etc.

The 3 ATMEL controllers were programmed with ASEM/C language , the smart

meter Server and the IVRS server GUI were developed using NI-LabView , the

mobile GUI was developed J2ME( Java 2 Micro-Edition).

SMART MTER REPSONSE

PRESENTED BY: TSOKOH FRANK GBESIMI

The response of the smart meter was tested

under the following operational conditions

• using mobile phone GUI

• using VOICE service

• using a PC LabView GUI

Conclusion

• The required SMART meter server/client with load control/monitor has been designed by means of LabVIEW graphical programming language , Micro-Java (J2ME) for the mobile GUI and embedded C and Assembly language .

• Real time current and voltage sensor( ACS-712) AND ADC0808-LCN were used with the controller to effectively acquire analogue voltage and current data.

• DTMF(Dual Tone Multi-Frequency was used to acquire and track user calls for IVRS request.

• The smart meter can be topped up remotely and within the meter itself
