The paper presents three mechatronics project courses for the students of the first degree of Bologna program at the University of Maribor, Slovenia. Three courses, Project I, Project II and Project III, are assigned to the project work in the second and third study year. First course, Project I is some kind of introduction into the project work and the students are almost fully supervised by the...
In this paper presents a power monitoring circuit for battery energy management system using operational amplifiers. The proposed scheme consists of a current sensing circuit with voltage output and an analog multiplier. The voltage output of current sensing circuit is directly proportional to load current. The multiplying result of the load current in the form of voltage signal and the load voltage...
This guide discusses operational parameters that may be observed by battery monitoring equipment used in stationary applications, and the relative value of such observations. Although this guide does not give a listing of commercially available systems, it does provide a means for establishing specifications for the desired parameters to be monitored.
A current sensing circuit which is fully integrated suitable for low voltage buck regulator is presented. The current sensing circuit presented operates with accuracy close to 100 percent. It is targeted to be fabricated with 180 nm UMC technology. This IC senses faithfully till frequencies 2 MHz and hence it works well for the buck converters whose switching frequencies are up to 2 MHz. It is designed...
The goal of this paper is to describe the challenges which have been faced in the design and implementation of a platform suitable for commercial wireless sensor-actuator systems. Battery life and cost have been the most important restrictions in the design, since they can determine the market success of a product. This paper presents the key issues that have been obtained, and how they have been...
In wireless sensor networks that consist of a large number of low-power, short-lived, unreliable sensors, one of the main design challenges is to obtain long system lifetime, as well as maintain sufficient sensing coverage and reliability. A critical issue in wireless sensor networks is represented by the limited availability of energy within network nodes; therefore making good uses of energy is...
Lifetime of a wireless sensor network is affected by key factors such as network architecture, network size, sensor node population model, data generation rate, initial battery budget, and communication protocols. We investigate accurate lifetime estimation of large sensor networks using discrete event simulation. Our experimental networks are large IEEE 802.15.4 compliant wireless sensor networks...
