INTELLIGENT COMPOSITE DISPLAY SYSTEM

Abstract

Intelligent Composite Display System is applicable for display of energy registration of multiple number of consumers consolidated at one point. It consists of micro-controller based unit with display driver, LCD-glass, serial ports and associated electronics. It also stores relevant data in the data memory. This memory is non volatile and keeps the information intact in case of power failure. It displays kWh, MD, Date, Time etc. in a scrolling fashion. The LCD is having 2 or more rows of multi digit multi segment displays to display individual kWh, MD alongwith current date and time in an manual/auto scrolling mode. The serial port is for data down loading using MRI. This is an individual unit, hence, repair/replacement at site is possible. In case of malfunctioning of the unit, it can be replaced without affecting the energy registration. Non-metallic housing is provided for protection against electric shock.

This is a stand alone display for energy registration. The conventional system available is for displaying different measured parameters of individual meter. This display is an integral part of the meter. So in case of a number of meters, individual energy meter with integrated LCD Display are being used for energy registration. This process of display is cumbersome and requires a lot of space for installation, for multiple number of meters in one place. PRIOR ART Due to passage of time, the dwelling pattern has changed from individual houses to "Residential Flats". Now-a-days even small scale manufacturing & service industries are operating at "Flatted Factories". Thus it is obvious that there are large numbers of individual customers in one premises now. So with the existing system of displaying the energy registration and other parameters are provided separately for each and every meter individually. This makes the cabling system for individual meters very lengthy, clumsy, jumbled up, cumbersome. Fig. 1 shows an example of existing layout for 4 nos. of Single Phase Meter installation & its complexicity. Even physical placement of multiple number Energy Meters become difficult due to lack of available space. Also if display is not working properly entire meter is to be replaced. Problem With Prior Art:- 1. In case of display malfunctioning the total energy meter is to be replaced. 2. Space requirement will be high due to installation of so many individual display units for each meter. Most houses and factory units do not have enough space to accommodate multiple meters & its wiring. 3. Repair / replacement at site of display section is not possible since it is an integral part of the meter. How this invention seeks to solve the problems:- The invention relates to an Intelligent Composite Display System wherein the energy consumption of a number of users can be displayed from one group metering units for multiple number of consumers. In this design, the intelligent composite display system is for the display of registered energy consumption of one or multi number of consumers. The invented design concept, shown in fig. 2, is suitable for display of energy registration and other related parameters for single phase, three phase or combination of single phase and three phase energy measurement system. The objects of the present invention are as under: 1. Display of energy registration of multiple number of consumers consolidated at one point. 2. This is an individual unit, hence, repair/replacement at site is easily possible. 3. In case of malfunctioning of the unit, it can be replaced without affecting the energy registration. 4. The display is at a consolidated point, hence, saving in space. The Intelligent Composite Display System according to the present invention is very convenient, space saving and easy to install and maintain. Since many apparently different embodiments of the present invention could be made without departing from scope and spirit thereof, it is intended that the description of the invention stated herein be interpreted as being illustrative only and not limiting in any manner whatsoever. FUNCTIONAL DESCRIPTION This is an individual micro -controller based unit with display driver, LCD - glass, serial ports and associated electronics. The signal received from the measurement unit through serial port is processed to display kWh, MD, Date, Time etc in a scrolling fashion in the LCD. The LCD is having 2 or more rows of multi digits multi segment displays to display individual kWh, MD alongwith current date and time in a manual/auto scrolling mode. The other serial port is for data down loading using MRI. As shown in Fig. 2, the functional description is as under: I- SERIAL COMMUNICATION & LOGIC CIRCUIT It receives registered energy data from energy measurement unit and then provides the information to micro controller for further processing required for display. It also enables the Meter Reading Instrument (MRI) connection for downloading of stored data. II. MICRO CONTROLLER & DATA MEMORY On receipt of information through communication port, it processes the received data, and sends required information to Display Driver for displaying data in LCD glass. It also stores relevant data in the data memory. This memory is non volatile and keeps the information intact in case of power failure, it also enables the Serial Port to be connected to Meter Reading Instrument (MRI) for data downloading upon request from MRI. HI. DISPLAY DRIVER It receives required information from micro controller & data unit and drives the identified signals to LCD display section for displaying data in LCD glass. IV. DISPLAY (LIQUID CRYSTAL TYPE) On receiving processed signal, LCD displays kWh, MD, Date, and Time etc. in a scrolling fashion. The LCD is having 2 or more rows of multi digits multi segment displays to display individual kWh, MD along with current date and time in an manual auto scrolling mode.
