Rancang Bangun Pengenalan Modul Sensor Dengan Konfigurasi Otomatis Berbasis Komunikasi I2C

Wireless Sensor Network merupakan salah satu dari sekian banyak teknologi yang saat ini digunakan di berbagai bidang. Namun pada kenyataannya untuk dapat membuat suatu sistem WSN dapat bekerja membutuhkan banyak waktu, pengalaman dan juga pengetahuan yang memadai. Hal tersebut dikarenaka sulitnya mengkonfigurasi suatu node agar dapat bekerja dengan baik. Agar sensor node dapat digunakan sendiri proses yang harus dilalui cukup rumit, mulai dari penyusunan rangkaian, pengkabelan, pemrograman dan lain-lain. Terlebih jika jumlah dari node yang ada sangat banyak, tentunya akan semakin merepotkan jika harus mengulangi proses yang telah disebutkan diatas. Salah satu solusi dari masalah tersebut yaitu dengan cara menerapkan sistem Modular Wireless Sensor Network dimana bagian dari node dipisahkan menjadi modul tertentu berdasarkan jenis dan kegunaannya. Jenis modul sendiri dapat dibagi menjadi modul core (perangkat pengendali), modul komunikasi dan modul sensor. Pada modul yang ada sendiri diterapkan sistem Plug and Play agar tiap modul dapat langsung digunakan tanpa harus melalui proses konfigurasi apapun. Pada penilitian yang dilakukan sendiri hanya berfokus pada modul sensor dimana nantinya modul sensor terdiri dari beberapa jenis sensor yang berbeda. Modul sensor yang telah diterapkan sistem Plug and Play dapat langsung digunakan ketika dihubungkan pada perangkat pengendali. Plug and Play sendiri diterapkan dengan cara membuat proses pendeteksian dan juga proses identifikasi jenis dari modul sensor yang terpasang. Proses pendeteksian dan juga proses identifikasi dilakukan dengan memanfaatkan komunikasi serial I2C (Inter Integrated Circuit). Dari hasil beberapa pengujian yang dilakukan diketahui bahwa proses pendeteksian, pengiriman data dan juga pemilihan modul aktif berhasil dilakukan tanpa mengalami kendala apapun

Home Automation and Transparent Data Transmission Using Single-Medium Network Concept

Tämän diplomityön tarkoituksena on esitellä uusi yleiskäyttöinen tietoliikenneverkko läpinäkyvää tiedonsiirtoa ja kotiautomaation ohjaussovelluksia varten. Tietoliikennealusta nimeltään Wiseriver on ubiikki (kaikkialla läsnä oleva) langallinen parikaapeliverkko, joka on suunniteltu vastaamaan kaikenlaisiin yksittäisiin tiedonsiirtotarpeisiin kodeissa ja rakennuksissa. Teknologia perustuu konfiguroitaviin protokollariippumattomiin tiedonvälitysresursseihin, joita kutsutaan käsitteellä virtual wire (virtuaalinen johto). Opinnäyte alkoi yleiskatsauksella vastaavanlaisiin jo markkinoilla oleviin teknologioihin, jonka jälkeen seurasi tarkempi perehtyminen Wiseriver-järjestelmän toiminnassa käytettäviin tiedonvälitysperiaatteisiin. Keskeisin osuus opinnäytteen tekemisessä oli näiden Wiseriver-toimintojen implementointi FPGA:lla. Implementaatio sisälsi RTL-koodausta, simulointia ja logiikkasynteesiä. Kaksi erillistä, mutta samankaltaista FPGA-toteutusta toimivat ohjaimina Wiseriverin isäntä- ja liitäntäsolmuyksiköiden prototyyppiversioissa. Kokonainen Wiseriverin järjestelmäprototyyppi puolestaan toimii perustana kehitettäessä järjestelmää edelleen pilottikohteeseen. Simulaatio- ja testaustyön lopputuloksena syntyi perustoteutus, joka kykenee välittämään läpinäkyvästi Ethernet-pohjaista liikennettä ja hallitsemaan yksinkertaista valo-ohjaussovellusta. Simulaatiotulokset ja ajoitusraportit osoittavat että toteutus toimii myös valmisteilla olevassa prototyyppilaitteistossa. Wiseriver-järjestelmän prototyyppivaihe sisältää useita eri tahtiin eteneviä osakokonaisuuksia sisältäen esimerkiksi piirilevy- ja ohjelmistosuunnittelua. Jatkokehitystä ajatellen on myös jo olemassa suunnitelmia järjestelmän laajentamiseksi edelleen.The purpose of this thesis is to present a new universal communication network for transparent data transmission and control applications used in home automation. The communication platform called Wiseriver is a ubiquitous wired twisted-pair network that is designed to meet all kind of individual data transmission needs in homes and buildings. The technology is based on configurable protocol-independent communication resources called virtual wires. The thesis was started by a general survey to related technologies already existing in the market and then followed by a more specific introduction to transmission principles used in the operation of Wiseriver system. The main contribution of this thesis was to implement these Wiseriver functions with FPGA. The implementation included RTL coding using VHDL, functional simulations and logic syntheses. Two different but similar FPGA designs are used as controllers in master and access node prototype components of Wiseriver. A whole Wiseriver system prototype in turn will be used as groundwork for developing a pilot system. The outcome of the simulation and debugging process was a base design that permits to transmit Ethernet based traffic transparently and handle a simple light control application. Simulation results and timing analyze reports indicate that the design works in completed prototype hardware. Other related developments such as PCB layout and software designs are ongoing during the prototype phase of the whole system. Also several follow-up developments have been already considered for improving the system

Real-time sensor data development for smart truck drivetrains

Heavy articulated transport vehicles have a poor reputation associated with dramatic road accidents with frequent fatalities for those in automobiles. The result of this work is a formal data flow structure to enhance real-time decision-making in complex mechanical systems to increase performance capability and responsiveness to human commands. This structure recognizes the multiple layers of highly non-linear mechanical components (actuators, wheel tire & ground surfaces, controllers, power supplies, human/machine interfaces, etc.) that must operate in unison (i.e., reduce conflicts) in real-time (in milli-seconds) to enhance operator (driver) control to maximize human choice. This work contains a discussion on dependable sensor data is vital in complex systems that rely on a suite of sensors for both control as well as condition monitoring purposes as well as discussion on real-time energy distribution analysis in high momentum mechanical systems. The focus will be on tractor trucks of class 7 & 8 that are outfitted with an array of low-cost redundant sensors leveraging advances in intelligent robotic systems. This work details many topics including: Most relevant sensor types and their technologies, Designing, implementing, and maintaining a multi-sensor system using feasible industry standards, Sensor signal integrity and data flow processing for decision making, Asynchronous data flow methods for operating decision making schemes in real-time, Multiple applications to enhance tractor trucks systems with multi-sensor systems for real-time decision making.Mechanical Engineerin

Sensor Networks and Their Applications: Investigating the Role of Sensor Web Enablement

The Engineering Doctorate (EngD) was conducted in conjunction with BT Research on state-of-the-art Wireless Sensor Network (WSN) projects. The first area of work is a literature review of WSN project applications, some of which the author worked on as a BT Researcher based at the world renowned Adastral Park Research Labs in Suffolk (2004-09). WSN applications are examined within the context of Machine-to-Machine (M2M); Information Networking (IN); Internet/Web of Things (IoT/WoT); smart home and smart devices; BT’s 21st Century Network (21CN); Cloud Computing; and future trends. In addition, this thesis provides an insight into the capabilities of similar external WSN project applications. Under BT’s Sensor Virtualization project, the second area of work focuses on building a Generic Architecture for WSNs with reusable infrastructure and ‘infostructure’ by identifying and trialling suitable components, in order to realise actual business benefits for BT. The third area of work focuses on the Open Geospatial Consortium (OGC) standards and their Sensor Web Enablement (SWE) initiative. The SWE framework was investigated to ascertain its potential as a component of the Generic Architecture. BT’s SAPHE project served as a use case. BT Research’s experiences of taking this traditional (vertical) stove-piped application and creating SWE compliant services are described. The author’s findings were originally presented in a series of publications and have been incorporated into this thesis along with supplementary WSN material from BT Research projects. SWE 2.0 specifications are outlined to highlight key improvements, since work began at BT with SWE 1.0. The fourth area of work focuses on Complex Event Processing (CEP) which was evaluated to ascertain its potential for aggregating and correlating the shared project sensor data (‘infostructure’) harvested and for enabling data fusion for WSNs in diverse domains. Finally, the conclusions and suggestions for further work are provided
