Case Studies Scanner System - Image Processing Due to patent expiry of an existing laser based scanning system, the client wanted to Design and develop an advanced system base on photogrammetry which accepts a 2D image with predefined targets and will give an output which is real world 3D coordinates (X, Y, and Z) of the target center points. • Intel based PC104 mother board • Pattern recognition algorithm. • Photogrammetric analysis to get the 3D coordinates from 2D image • Developed a camera calibration algorithm using the Direct Linear Transformation • Robust software developed for critical image capturing and Processing of the image and find 6DOF of targets within 250 ms. • Ethernet, USB 2. 0 and RS232 as the communication interfaces • Wi-Fi communication with server to transfer the identified target pattern. • Provided the Mechanical enclosure with a Rotating plate so the camera can capture images at different angles. Case Studies Time and Attendance Terminal The client wanted to develop a low cost alternative to an expensive time and attendance terminals using RFID Technology. They also required to implement 3G-UMTS technologies and add Ethernet communication for data transfer with the server and future online firmware upgrades for the system. • Hardware designed and developed using ARM 9 Core Processor. • Wireless Technologies used - Low frequency RFID, 3G-UMTS, Wi-Fi, GPS • Implementation of the 3G-UMTS technologies and Ethernet communication for data transfer with the server. • Equipped with various communication options USB/Ethernet/GPRS-EDGE. • Large Graphical LCD Display. • Linux operating system incorporated within the system. • Fingerprint sensor and RFID for identity verification. • VGA Camera with LED Flash for facial recognition • In- terminal Data Base management. • Platform devised for product road map of 10years. Case Studies Wireless based Biomedical & Food Monitoring application Wireless system used in Biomedical monitoring and Food monitoring application. It efficiently monitors and records a range of critical point data, including temperature, humidity, door status, goods receipt conditions and air quality, and provides effective reporting and visualisation for ongoing management. Hardware designed with i.Mx 25 processor from Free scale Ported with Linux Operating system Wireless communication at 868,900,902-928 MHz, Spread Spectrum Power over Ethernet interface Data logging with SD card Battery back up in case of the power failure EMI/ EMC compliant design Designed Front end application with User-defined reports Access levels and permissions Flexible reporting intervals Data export options Language options Different critical parameter sensors (with product simulant options) Customisable alarm notifications (email, SMS, LED message boards, PC pop-up windows, flashing lights) Case Studies Smart metering System – ZigBee case study The ZigBee-based system created a self-forming, self-healing wireless mesh network across neighborhoods and apartment complexes that link meters with utilities’ corporate offices. They can remotely monitor a residence’s electric, gas and water usage more efficiently with fewer errors and at lower costs, while improving customer service. Hardware designed with MSP430F2274 from Texas Instruments Meter Reading: Automatic Meter Reading and appointed meter reading Real time Clock (RTC) Working Minimum 2 years after power off Meter carrier capacity Daily Frozen data storage Save the succeed/failed meter reading time Save data when power off Digital Outputs Password protection PC based Front application for Collection Of Readings and Controls Case Studies Building Automation - Management System Energy monitoring and Management System. The system is based on wireless self healing networked topology and is capable for using existing power line as means of communication only in rare cases of wireless communication path failure. As a standalone solution (with out power line back-up) the wireless only Network system shall be ensured for at least distance coverage of 200 meters with 150 nodes. Hardware designed with Power PC Remote and touch screen based User interface. Intercommunication with the different devices implemented System Had following Interfaces RF based Remote Interface Burger Alarm Motion Sensor Dimmer unit Interface Skirting Light IR Interface User-friendly GUI Interface Case Studies Data Logger Front end application The system represents the latest in low cost data-logging technology. It can be used as an independent monitor to log the conditions second by second in any controlled or uncontrolled environment. Set the real time clock Define the engineering units of each input and calibrate them. Set alarm set-points, hysteresis (dead-band) and time delay for the two alarm points of each input. Link any of the inputs to act as the set-point of another input so you can adjust a set-point from other equipment Tabulate the results of the monitoring. This reporting feature allows you to select a time and date range for the report and select how many points you wish to report in that time period. The data is then averaged out but the maximum and minimum are still retained.
