  1. 1. PRESENTED BY: NAME: Tsokoh Frank Gbesimi STUDENT ID: S1344875 DEPT: MSc. Applied Instrumentation and Control (Oil and Gas) SUPERVISOR: Dr. Emad Mohamed
  2. 2. Statement of Project Task PRESENTED BY: Tsokoh Frank Gbesimi 2 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.

  4. 4. PRESENTED BY: TSOKOH FRANK GBESIMI 4 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.

  6. 6. PRESENTED BY: TSOKOH FRANK GBESIMI 6 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).

PRESENTED BY: TSOKOH FRANK GBESIMI 14 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
