billing system using 8051 microcontroller
#1

Hi am abinaya I would like to get details on billing system using 8051 microcontroller.. my friend said billing system using 8051 microcontroller will be available here and now I am living at sivakasi and I studing in the college mepco and now am doing mini project so I need help on doing mini project billing system based on 8051 microcontroller.

Billing is a performing arts term used in referring to the order and other aspects of how credits are presented for plays, films, television, or other creative works. Information given in billing usually consists of the companies, actors, directors, producers, and other crew members. This article examines billing for theatrical films.

This paper deals with the implementation of power line
network in the field of electricity billing. In the present
scenario power line communication (PLC) is one of the
economical ways of communication of data. Even though
there are new methods of wireless communication methods,
practically it is very much time consuming to install such a
system, and also it is highly cost consuming method .But the
power lines which already exist and connect every household
in a particular area is more advantageous as it does not require
any new installation or erection for establishment of
communication channels, and thus is not a time consuming
one . One biggest advantage of this system is that it can be
readily implemented, unlike the other modern methods. The
power line network can also be used for creating emergency
response networks. This project eliminates the need for
employing EB meter readers and this set of employees can be
used elsewhere. The long queues in the billing counter can be
avoided by implementing this model. Also the control of the
system is fully automated by this technique. The most
important feature in this system is the use of digital meters
consisting of micro controllers and real time clock, thus
eliminating the loss of meter data during power failure.

1. INTRODUCTION
Though many technological innovations are taking place in
this world, existing electricity consumption billing process
seems in India to be very obsolete and does not meet the latest
technology available. In this paper, the above said process is
totally automated and the communication is made possible
entirely through the power line [1]. Not only the billing, even
the control of system is fully automated by this technique i.e.
when a consumer fails to pay his consumption bill within a
given period of time the supply automatically gets cut off to
his house and the restoration is done only when the bill is
cleared. The currently prevailing system involves the user to
go up to the EB office to manually pay his bills. The readings
are taken using the analog meter present in the customer‟s
house. The readings are taken using an employee working at
the EB office. This system has some disadvantages like
erroneous readings, easy manipulation, manual labour and
time consuming. In the proposed system, the analog energy
meters are replaced by digital meters. The meter readings in
the form of digital data are transferred from the customer end
to the EB office through power line [2]. The meter readings
are collected at the regular time intervals (t) and the present
reading (t) is compared with previous reading (t-1) and the bill
is made ready as per the slab for the consumed units by the
customer [2]. At the EB end a computer maintains a data base
of its entire customer. Once the bill is generated, the
customers are provided with some grace period for the
payment of bill. If a customer fails to pay his/her bill, a trip
signal is sent to the trip circuit connected to the meter, through
the same network. Once when the bill is paid, the supply is
restored back. Thus the above system does not require any
person from the beginning of recording the meter reading to,
till the supply control when he/fails to pay the bill. The
advantages of this system are less labour, no more queues,
quick updates, no manipulation and cost effective. Hence no
more a EB personnel is required to come to the consumer
house to remove the fuse to cut off the supply which is the
oldest EB tradition followed, even at the present stage.
2. PRINCIPLE OF POWER LINE
COMMUNICATION
Each household is allocated a particular ID so that they can be
uniquely identified. There is no chance of manipulation in the
proposed system. The network path is also not fixed. This
helps in creating a dynamic environment as there is no fixed
path in the network. The data sent by the home unit then and
there is automatically stored in the back end database at the
EB office. This saves hours and hours of manual data entry
needed for entering the data into the central system. The
power line communication used here is a bi-directional
communication enabling data transfer at a faster data rate
through long distances. Also power lines may be noisy at
certain times due to interference. In such a case the data
transmission may be disrupted. Hence a dedicated micro
controller is used to enable data transmission even in the
noisiest power line and also at any weather condition [3]. By
digitizing, the currently used analog energy meter has been
completely transformed to a digital one. Hence it is beneficial
to the customers as the system is made very user friendly. The
automated EB billing procedure has the ability of fulfilling a
set of needs for the user and the EB workers [2].
1. The automated EB billing system eliminates the need to
pay the bills at the EB office.
2. This system allows the user to get updated regarding the
details of the power used in his house.
3. The user can also verify if the bill received is the right one
or not.
4. Automatic supply tripping and restoring under the case of
failure in bill settlement by the customer.
5. The new system is readily adaptable and hence less time is
consumed to implement this system.
This paper being advancement to the proposed project of
sending the details to the customer house, it has a few
objectives which have to be met.
1. Presence of a meter ID at each house and a node ID to.
