Abstract: In the modern era of technology electricity is the essential part of the daily life. For its proper utilization, it should be used very judiciously. But in India, The electricity supply scenario is totally different as in urban areas availability of electricity is surplus but in villages it is not possible because of policies in distribution and lack of exact requirement estimations. Also the consumers are not satisfied from the electricity department for their services like errors in electricity bill, delay in bill generation etc. Thus to avoid human intervention for minimizing technical errors and to reduce human need at the same time GSM based AMR is the best solution to this. In an electric power system there are three basic pillars generation, distribution and the metering system. Function of generation system is to generate electricity from thermal power, hydro power etc. Function of distribution system is to distribute the electricity in the network to end users. The function of the metering system is to measure the electricity consumption of the end users for billing. Basic role of metering system is to measure the electricity usage of the end consumers, which must be accurate and reliable. The metering system is reliable only when the readings of electricity consumption at user end and the reading measured by the energy meter are same and accurate, for that efficiency of the metering system is totally based on the reliability of the meter reading. Keywords: AMR, DTU, EPROM, ID, MCU, RS232.
1. INTRODUCTION In present scenario, a person from the electricity department at the end of each month goes to every house and takes the meter reading manually. These readings are used for the bill calculations by electricity department and after generation of bill it is distributed among the users. Bill payment by the end users may be either online or by offline mode.. In this manual processes lots of manpower is required for meter reading, bill generation, and bill distribution work. But a new technology called AMR (Automatic meter reading) is introduced in the system to overcome the above drawbacks because it is an economical solution. AMR is a new and simple technology which is used to gather data from energy metering devices and transfer it to a central management unit for billing. AMR reduces the problem of meter reading by meter reader faced by almost all electricity departments. Other technology like a meter reader with hand held unit goes to every house and collects the meter reading. This is also a very quickly process of collecting meter reading without manual intervention. The billing software can download the data for bill generation, thereby avoiding any error in data entry. But still lots of manpower required for collecting data from end users premises. In more advanced options, the AMR system can automatically read the data and store it in the data base for billing without individual intervention. For knowing how AMR works first install an AMR system at a particular location or user premises. The fig.1 shows the how automated meter reading works. The meter interrupts when user consuming the electricity. Electricity department will be using this data for processing bill calculations and other future forecast. Interruption of meter means microcontroller receives a message through GSM modem. Microcontroller checks the authentication.
