The unattended electromechanical equipments are widely distributed in the harsh environment, which makes it difficult to construct the monitoring system. Therefore, this paper proposes a solution of the remote monitoring system based on Internet, which applies the VLAN (Virtual Local Area Network) technology in constructing the network. The network microprocessor STM32F107 is adopted to design a low-cost remote information terminal. The system software is designed based on B/S (Browser/Server) architecture by ASP (Active Server Page) technology, which implements SCADA (Supervisory Control and Data Acquisition) and pre-warning system for the unattended electromechanical equipments. The application shows that the system is stable, reliable and worth popularizing.

This paper provides details concerning the design of an integrated voice and data communications link for a Local Area Network that must utilize residential type 2 pair telephone wiring as its transmission medium. The communications link can provide a worst case total data rate of 80 K bps (full duplex), 80 K analog samples of audio signals total (full duplex), as well as power and ground for remote terminals. In a system design that utilizes the communications link discussed here, the above total values of data and audio information flow can be divided by the number of terminals anticipated in the system in any ratio desired. The intent of the design of the communications link is to provide what is believed to be the most cost effective means of implementing an intelligent network of consumer based products in a residential or small business type of environment. In this document, the original technical problem is discussed along with details concerning the development of the solution presented here. The system design example that is presented is only provided as an aid to understanding how the communications link can be applied and is not the focus of the central concept. In that example, the system is comprised of 8 remote terminals and one central control terminal — all of which are voice and data devices. Therefore, the available continuous data rate per terminal is 10 K bps with 5 Khz full duplex audio.

<span>Local area network (LAN) as Bluetooth, WiFi and ZigBee are well established technology. The biggest problem with many LAN is the battery consumption and short ranges link budgets. LoRa is a new, private, unlicensed and spread spectrum modulation technique which allows sending low rates at extremely long ranges with minimal power consumption. More importantly, there is no access fee associated with this type of wireless technology. The main idea behind this work is to conduct performance and capability analysis of a currently available LoRa transceiver. We develop a location monitoring system using LoRa and global positioning system (GPS) module and we analyze the detectable range of its data, its battery consumption as well as received signal strength indicator (RSSI). Our deployment experiment demonstrates that the sy<span>stem is able to detect the transmitted data within 290 meters of distances. Using 6 volts of battery AA, the transmission of data still occurred after 24 hours</span>. <span>This project is emphasized a location monitoring system that provide low power usage</span> but long range.</span>

Abstract The article discusses the possibility of creating a system for automating the process of searching and assessing the danger of targets using machine vision and existing ship systems. The technologies for processing images from the ship’s camera system are analyzed: object recognition by a ready-made convolutional neural retrained network, as well as object detection by SURF algorithms. The parameters of the danger of goals within the framework of the problem to be solved have been analyzed and developed, and a structural analysis has been elaborated. The functionality of the automatic operation of the system as a closed circuit has been considered. To achieve the technical result in the system as an integrated part of the ship’s equipment based on cognitive information processing, a composite information object from the ship’s sensors and control systems was introduced. It is decomposed into blocks in which the associated logical information processing takes place using basic modules consisting of adaptive cells-approximators as learning elements capable of independently processing information. The following units are included in the local area network: an information support unit (ISU), a decision making unit (DMU), a command-organizational unit (COU) with an operator’s workstation. The ISU is connected by a two-way communication output with aggregate LAN units, the other output is connected in series with a situation determination unit and the “model of the surrounding space” block. The survey was carried out on board a modern LNG gas carrier using ship systems.
