Behera, Somanath (2015) GSM Based Energy Meter. BTech thesis.
The TM4C123GH6PM board is the most recent system-on-chip (SOC), which falls under ARM family of boards and devices. This family of boards and devices comes under the powerful 32-bit ARM family after adding a lots of new features, properties and flexibility to support robust single, 2 and three phase metrology solutions. This project is only for domestic uses as we have considered only the single phase case. We can also extend this project for two phase and three phase environment. In that case this will be very helpful for industrial application. Here we take input as current and voltage from the main supply and we use sensing circuits to make its level compatible with that of ARM Processor. Here the GSM module is added to reduce the manual work and complexity of analog meters. Here we can send sms to every individual about their energy usage. The calculation and data sending capacity of this model is made easier by the source code. Handling these complex systems easily with the help of software has made it more popular. Higher level of current capacity can easily be obtained by simple replacement of the shunt resistor or its value. We can achieve any desired value by either by changing the ratio in transformer or the resister value of voltage divider circuit. The TM4C123GH6PM has a powerful 60 MHz CPU with ARM architecture. The analog front end consists of up to two channel of 12-bit analog-to-digital converters (ADC), with conversion time 2.44 micro second per channel. The software supports calculation of various parameters for single phase energy calculation. The key parameters measured during energy measurements are: RMS current and voltage, energies. Finally the calculated value of power and other parameters are displayed on 16x2 LCD and the same data is sent to user and station via SMS using GSM module.
