GSM AND AD-HOC WIRELESS ROUTING FOR AUTOMATED EB BILLING SYSTEM
[attachment=25495]
DISADVANTAGES
1. Erroneous Readings – This involves errors present in the meter reading which are committed due to human mistakes.
2. Easy Manipulation – Since all data here are taken manually dates’ can be easily manipulated by third parties which affect the EB office and the customer
3. Manual Labor – The amount of workforce involved in this prevailing EB system is too large as the EB people have to visit many areas at roughly the same date.
Advantages of automated EB billing system
• Automation of all features including communication from the EB office to the customer.
• Saves data using automatic control and storage systems.
• It involves less cost to communicate.
• This system increases productivity.
• To increase n number of customers to communicate and automate.
Objective
1. Presence of an RF ID at each house and a central RF ID at the office to manage the RF ID at the house
2. Encryption techniques present at each house for securely sending the data
3. Matching circuit at the EB office to correctly match the house ID to the customer ID
4. A consistent database of all the details of each house
EB OFFICE MODULE
The EB office module consists of a database at the
back end for storing values which are got from the home module via RF waves. After the values are got from the home units the cost is calculated and the values are sent back to the home unit and they are displayed in the LCD display for the user to make note of it. Also the cost and amount of units are sent as a SMS to the customer's mobile phone. The data’s are transmitted and received using RF transmitter and RF receiver. There is an encoder and decoder both at the central office and also at the individual home units. This facilitates secure transmission and reception in the system. The max232 interfacing is done for reducing the voltage flow from 7.5-15v to 0-5v .this will prevent the circuit from melting.
