This paper presents a real-time, low-cost, wireless, AC and DC monitoring system based on an ATmega328P-PU microcontroller. The proposed system is composed by different client nodes, which have the task to measure the main electrical quantities involved in the system, and a server node that collects the data and send them to a display device. The system is well suited for a good accuracy monitoring...
Microgrids are a collections of loads, small sources and storage systems which are present as single, flexible and independently controllable entities [1]. The inclusion of Distributed Generation (DGs) systems into a microgrid makes the current flow in a microgid bidirectional. The detection of faults and the connection and disconnection of the DGs to and from the microgrid is carried out by the Central...
In this work, a structure of the controller for registering passenger flow (CRPF) of public transport for the “smart” city system was designed. Controller operation based on the use of cheap mini-computer Raspberry Pi. Structural model of the controller was built with using the method of simulation by Petri nets. Software and hardware for controller was developed, the particular implementation of...
Angkutan Kota (angkot) is one of public transport that often used by citizen in Bandung. But, there's still a lot of citizen that use private vehicle instead of using public transportation like angkot. This is due to the services provided by public transport hasn't been satisfactory. Therefore, to improve the service of angkot, angkot's payment system should be improved by making a payment standard...
In the online world, service providers allow users to upload data to be stored or processed. In some cases, privacy will become an essential feature. Sensitive content can be the data provided to or the services used at the service provider. Logging of the actions of the service providers can therefore also generate privacy-sensitive content. However, to enhance transparency towards users, logging...
This paper presents a solution for the Wi-Fi reconfiguration of FPGAs. A design that manages the reconfiguration process of a Xilinx Spartan-3 FPGA by using a Wi-Fi Tag4M device that receives reconfiguration data wirelessly from a Configuration Server was developed. This research is especially important for adding self-healing capabilities to large and complex digital systems.
Police-using firearms management aim to effectively monitor and manage the following links about firearms, saving, in or out of storage, transportation, using, carrying, recycling etc. This paper introduces a kind of design and realization of master-slave firearms management system based on RS-485 bus technology. This system uses the network system with half-duplex and multi-computer communication...
This paper presents an architecture and a field implementation for a flexible and scalable distributed access control and management system, with application to the educational environment. The distributed control modules are developed based on embedded systems. Embedded systems are becoming increasingly common due to the fast deployment of advanced microcontrollers offering high processing speeds...
Currently, the network security appliance is one of the most important research topics in IT security. The use of log files for further security analysis was proven their importance in the development of a three DNS query traffic based detection model system for a proactive detection of security threat in the university campus network. In the current detection strategy we can detect some suspicious...
With the growth of the demand for voice recording in the fields of railway and electric power, many kinds of digital voice recorders have appeared. General voice recorders can only record voice produced at one place, when voice appeared in many different places need to be recorded centrally, these kinds of recorders become helpless. The problem can be solved with a kind of network-based voice recording...
This article broaches the sample implementation of the WWW Module for Intelligent Housing system, based on a single-chip, 8-bit microcomputer, which was scope of the master diploma thesis of one of the authors. It describes both the hardware and software part of the module with special focus on the solution of pseudo-parallel processing of network data, including the way of handling many network connections...
This paper presents a method for exploring communications capabilities of enhanced DS80C400 MAXIM/Dallas microcontroller, as a LAN server. Gravity mass lies in the implementation of several Java layers, working on server and client platforms. The LAN server is the MAXIM-Microcontroler System TINI, which itself is written in Java. Further in this paper are described results the experiment with TINI...
