Hardware Platform for Mobile Adaptable Surveillance System for Critical Areas

Abstract: Smart Environment is built with the help of embedded system that can give an access to the environment in which it is placed. The embedded systems are electronic systems constituting electronic devices which are specially built to facilitate certain processes such as the human interaction with an environment. These systems play a vital role in an electronic application systems such as  medical diagnosis, geological investigation, surveillances, cash records, play stations and etc. The Mobile Adaptable Surveillance System for Critical Areas (MASURCA) is an embedded system wireless sensor network application system that embodies both the hardware (node) and software. In this thesis project, Development of Hardware Platform for Mobile Adaptable Surveillance System for Critical Areas, the design and development of the hardware platform for the system is built. The project deals with building the smart system comprising of radio frequency (RF) radio, global positioning system (GPS) sensor module, Accelerometer, Temperature sensor, and Ultrasonic sensor.  The design focuses on designing the power supply stage from a single AA battery in such a way that the entire connected components and sensors get a required supply source with best possible extended battery life. The design of power supply stage includes EMC, signal integrity, thermal and efficiency design considerations, and prototyping and testing of the power supply stage.  First the sensors and the necessary design components are selected with more emphasis on their power/energy consumption, size of footprint and signal output (I2C-bus protocol interface capability). Then the system schematic will be designed and simulated for signal integrity and design rule using the Mentor Graphics design entry Dxdesigner and hyperlynx Analog simulator. The designed schematic is also packaged and the part is listed and the bill of material is generated so as to be able to annotate to the PCB layout and later component placement.  Likewise, the PCB layout is designed according to the Saab Training Systems AB’s standards, regulatory guidelines and standards, and the MASURCA main node system specific requirements. The project will also design and provide the mechanical enclosure kit and software development kit for the MASURCA main node hardware platform. Finally testing and evaluation of the system is done to make the hardware ready for the application implementation.
