, Description:Field of the invention:
The present invention relates to an Automated Meter Reading (AMR) system (IoT device based on GSM) that can be achieved by installing a module to the meter and by registering on app or website. More specifically this device is able to get and monitor customer’s meter readings.

Background / prior art:
The present invention relates to the automated meter reading system. In traditional method, meter reader visits the houses to take the reading of meters, entered them in the register, brings back the readings to the office to calculate and generate bills which are then sent to the consumers. Following describes a few related arts in this particular area to consider as state of art particularly in this area.
With the many fold increase in the number of meters, it is now practically impossible to cope up the workload with the available limited resources. In retrospection of the existing system, it is observed that this system, largely manually managed and error prone, inaccurate, time consuming, open to manipulation thus may lead to corruption.

US 5,897,607 disclose AUTOMATIC METER READING SYSTEM which describes a method and apparatus for measuring use of a commodity and for transmitting the measurement over a global computer information network to a remote location. The apparatus comprises a data acquisition and reporting device and an automatic meter reading device operatively arranged to measure use of a commodity and transmit the measurement over a global information network to the data acquisition and reporting device.

US 5,590,179 discloses Remote automatic meter reading apparatus describes Instantaneous current and Voltage values are digitized at each of a plurality of electrical utility customer sites and integrated by a processor to calculate electrical power con summed at each customer site. A communication interface couples the processor at each customer site to a central processor in a central utility site to communicate the power consumed values of each customer site to the central utility site. In a preferred embodiment, the automatic meter reader apparatus is mounted in an electrical watt hour meter socket adapter which plugs into a watt hour meter socket at each customer site. Telephone modem circuitry mounted in the socket adapter connects to telephone lines to communicate calculated power values from each customer site to the central utility site.

It is understood that rate of electricity consumption depends upon the range of consumption i.e. if the power consumption is more for a particular month, the consumer may have to pay higher rate. Now the visit of meter readers is often not fixed means in one month, he may visit on 20th and next month, he may visit on 25th thus calculating readings (which is present reading minus previous month reading) for more than one month period. If the reading happens to fall in higher range bracket, the poor customer has to higher price.

Similarly, a consumer narrated the following related to meter reading. one day he noticed that the electricity bills received by him was much higher than usual. Initially he thought that it may due to summer season when ACs etc. were on, But the pattern persisted and he visited the distributor’s office. As usual he got a cold response and had to file in consumers’ forum. He has to search old bills to show the pattern changes and with the intervention of the Forum, the company agreed to look into. It was revealed that the meter went wrong and the speed of the wheel which revolved to measure the power consumption was doubled. The customer got back his money but after a lot of efforts and mental agony.
Thus there was a strong felt need to introduce an efficient, error-free instantaneous system with least involvement of human.
The present invention deals with a solution to overcome the difficulties of existing system by using latest technologies. The solution is simple & user friendly. Customer has to install module software to individual Meter and register the APP on website. It will give access to know the electricity consumption related data. The system will provide many facilities like statistical analysis of power consumption, interactions with consumer. The scope of future improvement/additional facilities in the system is also there.

Following terms describes the accessories as it has been described herein in Automatic Meter Reader IOT device based on GSM

LDR:
A Light Dependent Resistor (LDR) or a photo resistor is a device whose resistivity is a function of the incident electromagnetic radiation. Hence, they are light sensitive devices. They are also called as photo conductors, photo conductive cells or simply photocells. They are made up of semiconductor materials having high resistance. There are many different symbols used to indicate a LDR, one of the most commonly used symbol is shown in the figure below. The arrow indicates light falling on it.

A light dependent resistor works on the principle of photo conductivity. Photo conductivity is an optical phenomenon in which the materials conductivity is increased when light is absorbed by the material. When light falls i.e. when the photons fall on the device, the electrons in the valence band of the semiconductor material are excited to the conduction band. These photons in the incident light should have energy greater than the band gap of the semiconductor material to make the electrons jump from the valence band to the conduction band. Hence when light having enough energy strikes on the device, more and more electrons are excited to the conduction band which results in large number of charge carriers. As a result of this process, more and more current starts flowing through the device when the circuit is closed and hence it is said that the resistance of the device has been decreased.

ARDUINO UNO:
The Arduino UNO,developed by Arduino, is a widely used open-source microcontroller board, based on the ATmega328P microcontroller. The board is equipped with sets of digital and Analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. The board features 14 Digital pins and 6 Analog pins. It is programmable with the Arduino IDE (Integrated Development Environment) via a type B USB cable. It can be powered by a USB cable or by an external 9 volt battery, though it accepts voltages between 7 and 20 volts. It is also similar to the Arduino Nano and Leonardo. The hardware reference design is distributed under a Creative Commons Attribution Share-Alike 2.5 license and is available on the Arduino website. Layout and production files for some versions of the hardware are also available. "Uno" means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform. The ATmega328 on the Arduino Uno comes pre-programmed with a bootloader that allows to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol. The Uno also differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter. The Arduino UNO is generally considered the most user-friendly and popular board, with boards being sold worldwide for less than 5$ (Fig.3)

GSM/GPRS MODULE SIM 900A:

A GSM/GPRS Module is an IC or chip that connects to the GSM Network using a SIM (Subscriber Identity Module) and Radio Waves. The common radio frequencies in which a typical GSM Module operates are 850MHz, 900MHz, 1800MHz and 1900MHz.Since it is not possible to interface a GSM/GPRS Module directly to an external device like a microcontroller, we need a setup like shown in the following image.
It consists of the GSM/GPRS Module, slot for inserting a SIM Card, RS-232 Interface for connecting with computer or a microcontroller, signal status LED, power supply and a provision for connecting microphone and speaker.
Each GSM/GPRS Module is unique and it can be differentiated by its IMEI Number. IMEI or International Mobile Equipment Identity Number is a 15 – digit unique number associated with mobile phone, satellite phones and other GSM Network devices.

With the help of this GSM/GPRS Module, following tasks can be done.

• Make, receive or reject voice calls.
• Send, receive or delete SMS messages in the SIM Card.
• Add, read and search the contacts in the SIM Card.
• Send and receive data to / from the GSM/GPRS Network through GPRS
All the above-mentioned tasks can be accomplished with the help of Attention Commands or AT Commands. AT Commands are a part of Hayes Command Set, which are defined originally for a modem. GSM Network also implements a similar AT like commands for its GSM Modules.
The processor or controller to which the GSM/GPRS Module is connected to, is responsible for sending the AT Commands to the module. In response, the GSM Module performs command specific tasks like answering a phone call; send an SMS Message, etc.
SOFTWARE:
Following software is used for designing applications.
• ANDROID STUDIO
• Java Enterprise Edition, Ajax, HTML.
• Cloud
• Google Maps.
In a preferred embodiment, LDR (Light Dependent Resistor) is attached on the top of calibration LED of Electricity Meter and LED & LDR are provided dark covering so that LDR can detect the blink of calibration LED. Whenever calibration LED blinks the LDR detects this as LDR is set to detect light radiation of greater or equal to 50Hz. LDR is supplied with 3.3V from Arduino Uno to its one terminal and other terminal is connected to Analog input A0 of Arduino Uno. The Arduino Uno regularly checks for input at Analog pin A0 and as soon as input is detected it increments the value of energy consumption in Arduino Uno, On receiving input from LDR the Arduino Uno initializes GSM services to transmit reading to centralized database using GPRS services. GSM Module’s Tx(transmitter) pin & Rx(receiver) pin is connected to digital pins D9 & D10 of Arduino Uno board and to connect these Software serial library is used. Arduino Uno initializes the GPRS services by providing APN (access point name) and password of the SIM inserted in GSM Module and Hence, use of this SIM enables transmission of data to distant centralized database. After GSM Module is initialized the type of protocol i.e. HTTP protocol is selected and method used if GET, Now the value electricity consumption and unique Meter ID is passed as parameter to URL and are the transmitted to Database as illustrated in Fig 5,6.
Once data on the centralized server, it is now utilized by Web application as well as Apps for smart phone, where the user real-time consumption is displayed. Bills are generated. Blackouts in the areas are plotted on the map using Map API. Reading or consumption of area is displayed on the Map. SAIFI (System Average Interruption Frequency Index)& SAIDI (System Average Interruption Duration Index)indices are calculated and load analysis is done for power distribution.
Following are the advantages of the applications of the proposed invention.
• Remote Access to Energy consumption.
