Software Implementation of a PC-Based Home Surveillance System

This report is written upon the completion of the two semesters of Final Year Project course in Electrical & Electronic Engineering programme. This project is entitled as "Software Implementation of a PC-Based Home Surveillance System". The main objective of this project is to design and build software system, emphasizing on GUI for the PC-based home surveillance system. The developed software is called the "Home Guard System". The "Home Guard System" is designed to scan and display a number of input signals using sensory interface and represents them on the computer interface. The input and output modules are interfaced with the computer via a serial port. Microcontroller is also implemented to translate and manipulate the data received from the serial port into meaningful functions for prototype demonstration. The scope of study for this report mainly involves the software development process; the tools, services and packages available in Java that can be used for this project; and implementation of microcontrollers, specifically the PIC 16F84 to be used in the prototype development and construction. This project development is divided into three main modules, which are window module, hardware module and prototype module. In the window module, the GUI of this application is designed. The hardware module involves the communication establishment with the computer's serial port, while the prototype module consists of a circuit that implement PIC 16F84 as its processor. This project has been successfully completed. Several recommendations are proposed to improve the current system, and come up with a better presentable, secure and reliable system with additional functions

Autonomous greenhouse gas measurement system for analysis of gas migration on landfill sites

This paper describes the design, development and validation of an autonomous gas sensing platform prototype for monitoring of the greenhouse gases, methane (CH4) and carbon dioxide (CO2). The deployment undertaken for validation of the developed prototype monitored landfill gas migration to perimeter borehole wells on a landfill site. Target gas concentrations were captured via infrared gas sensors tuned for each target gas and data reported to an offsite data collection point at 12 hour intervals. This bespoke platform and the accompanying data recording and interface software provide a flexible alternative to the presently employed labor intensive, manual monitoring routines. This successful trial brought about a change in the management of the trial sites gas extraction system

Custom Circuit for Temperature, Pressure Sensing and Wireless Data Collection and Transmission

The purpose of this project was to create a network of sensors and software that would let the consumer monitor the product that was purchased from Parker Hannifin. This information was to be wirelessly transmitted to a computer that a technician would carry around and download to view the performance of the system that the network of sensors was built for. The telemetry module would be sufficiently flexible to handle the expansion of various types of telemetry inputs without large additional investment in telemetry collection hardware. The module controller would store, process and transmit the data to a remote station wirelessly over a certain distance. The wireless telemetry system is composed of the following components: pressure sensors, thermistor, thermocouples, motor speed sensor, data acquisition system, microprocessor, internal flash memory, wireless transmitter, wireless receiver, computer and a custom program that will decipher the information downloaded from the remote station. These components were researched, analyzed, modeled and selected to achieve specific performance criteria that will be covered in more detail later in this report. Each sensor was wired to the microprocessor board. The sensors provide analog information. The data would go through an analog-digital-converter in ordered to be stored in the memory on the board. A wireless system has been developed that is based on the industry standard IEEE 802.15.4, which is the leading technology for short-range wireless connectivity. The use of an industry standard ensures modularity and interoperability. The custom software can take the digital values from all the sensors and display the information in a graph. The technician would be able to see how the temperature and pressure acts with the speed of the motor. Also, the computer would also point out if any of the sensors fell out of the desired range

Design Strategies For Human Centered Sensor Networks

Sensor networks hold great promise in a variety of applications, and have been the subject of a great deal of active research in recent years. Similar to large scale computer networks, such as the internet, sensor networks are in essence information gathering mechanisms. In addition, sensor networks directly gather information about their environment, making this information available at what could be considered an extremely low cost. This feature is in part responsible for their wide applicability, but also makes sensor networks fundamentally different from other network technologies. This dissertation examines the construction of two sensor network systems, and asserts that, among sensor network applications, there is a critical distinction between those which are human-centered and non-human-centered. The first of these two particular systems used sensors embedded in an indoor environment to assess the movement of persons throughout the space. The second is the development of a medically oriented system which includes primarily wearable sensors. Through a discussion of their design and construction, we will distill design strategies for constructing such systems, particularly noting features which separate human-centered and non-human-centered systems

Hybrid mobile positioning managment framework based on radio communication and global positioning approaches

Mobile devices location systems for remote objects (vehicle, person, commodity, etc.), such as RTLS (Real Time Location System) in general and AVL (Automatic Vehicle Location) particularly for vehicles and persons, are increasingly used today by several enterprises. Indeed, this facilitates the management of personal, products, increases productivity, and so on. These systems use positioning devices such as GPS and communication devices to send remote location data. The first constraint of GPS is that it does not provide a precise position at any time. The extensions of GPS such as WAAS systems and A-GPS, that improve the precision, have also other constraints (availability and cost). The second constraint comes when sending remote location data. Often, the communication devices used for this purpose are GSM modules that send data on the GSM network. The use of GSM network is expensive to send data periodically. To overcome these drawbacks (improve precision and send data with minimum cost), we propose a framework on hybrid mobile devices management system to create a reliable and optimal location system by: i) coupling the radio devices at low integration cost with GPS devices, ii) allowing different mobile objects to cooperate and deliver the positioning data to the remote server

Intrusion Detection In Wireless Sensor Networks

There are several applications that use sensor motes and researchers continue to explore additional applications. For this particular application of detecting the movement of humans through the sensor field, a set of Berkley mica2 motes on TinyOS operating system is used. Different sensors such as pressure, light, and so on can be used to identify the presence of an intruder in the field. In our case, the light sensor is chosen for the detection. When an intruder crosses the monitored environment, the system detects the changes of the light values, and any significant change meaning that a change greater than a pre-defined threshold. This indicates the presence of an intruder. An integrated web cam is used to take snapshot of the intruder and transmit the picture through the network to a remote station. The basic motivation of this thesis is that a sensor web system can be used to monitor and detect any intruder in a specific area from a remote location

Intelligent Cold Supply Chain Management System with Radio Frequency Identification, Global Positioning System, and Wireless Sensor Network

This thesis establishes an intelligent cold supply chain management system which consists of two parts: one is the intelligent tracking system integrated with Radio Frequency Identification (RFID), Global Positioning System (GPS), and Wireless Sensor Network (WSN); the other is the cold supply chain model. This tracking system is mainly designed to monitor the food products during the transport, including two parts, a data terminal and a data server. The data terminal is installed inside a container, comprised of GPS, Bluetooth, industrial computer, WSN, RFID reader, RFID antenna, and Code Division Multiple Access (CDMA) modem. The data server is a computer which is able to access internet and has one Structured Query Language (SQL) database. Related application programs are developed with JAVA language. The whole system is successfully tested and meets the expectations we desired at the beginning. In this study, a refrigerator is used to simulate the environment of the container. The data terminal collects all information, including temperature inside the container, GPS location, Product's Identification, and current time in five minute intervals (customers will be asked to set this time interval at the beginning). CDMA cellular network provides the communication between the data server and the data terminal. The data server receives all information and saves the information in the SQL database, which can be used to predict the food safety. Advantages of this tracking system include the ability: 1) to trace and track the products starting from the suppliers to retailers; 2) to monitor and store important parameters during the processing and distribution of food products, such as temperature; 3) to communicate in real time for prompt response; and 4) to quantify food safety prediction. The objective of the model developed in this study is to maximize the profit of the cold supply chain. There are one distribution center, multiple retailers and suppliers involved in the cold supply chain. Since the real-time quality situations of products are available even during the transport, retailers can set prices of products based on the real quality situation. The company is able to dynamically plan the quantity of distribution from the distribution or suppliers' site. In addition, retailers are able to manage the inventory based on the real shelf life of products. This thesis also concludes all different inventory results for retailers under different scenarios which can help retailers to predict and manage the inventory. The optimization software, Lindo, is used to demonstrate that this model is capable to dynamically plan the distribution quantity. The sensitivity analysis for prices, transportation costs, and holding costs is discussed to simulate different situations during the transportation and distribution
