They are discussed in details the design project, function and realization of real-time monitoring water supply system in configuration software and the result is given. The project has been in use in water supply system of Xi'an Xianyang International Airport. It indicates by operation that the design project is practical and stable.
Next-generation gaming systems enable users to interact with the consoles without the need to touch a game controller. To achieve a more interesting game for two players, we present an interactive boxing game system using motion sensing and analysis. Our system can be described in twofold: (1) Hardware structure, and (2) Software flowchart, which integrate image and video processing techniques for...
In order to meet the current water resource management automation and remote monitoring needs, a GPRS-based real-time management system is designed, which includes terminal subsystem, master station subsystem and communication service subsystem. The terminal subsystem is developed based on STM32F103X microprocessor and GPRS network. The GPRS module of MC55 is used to realize the remote wireless data...
Unattended surveillance of public transportation infrastructures that may generate alarms in the case of a destructive event, and provide information on the current status of the infrastructure as well as on the short interval before the event, can empower the Search and Rescue teams with useful information that may save lives increasing their overall effectiveness. This paper presents a novel system...
Error correction techniques allow system recovery but usually do not remove completely latent faults. Although system continues working properly, some components can store faulty data. Authors analyze the effect of accumulated errors and possible solutions for systems thought for autonomous operation like aerospace on-board equipment.
For quick realization of controller design and optimization of parameters in a project, avoiding the long-time and danger during debugging the project, a new co-simulation control method based on dSPACE and Siemens PID module FM355C was introduced. In this method the close-loop control system was set-up with the rapid control prototype method based on the dSPACE and its hardware environment, using...
The growing number of customers and their specific application domains for the NH90 has led to an increasing number of functionally different helicopter variants. In order to cope with the high number of software variants, the NH90 software team has developed a software architecture that is based on Software Product Line (SPL) principles. Military avionics systems are constrained by many factors that...
Complex Event Processing (CEP) is a powerful technology for implementing real time applications. It offers efficient processing of occurring information pieces, so called events, based on an architecture that provides strong decoupling of its components: event producer, event processors and event consumer [4]. For this CEP is seen as an important contribution in future information systems. CEP applications...
This essay introduces a specific speed timing system used in cycling, which was built by the skill of electrommunication, network communication and database technology. In this system, a wireless real-time timer technique was adopted and communication master station was used. As a result, timing data can be real-time transmitted, stored and analyzed. Owing to the special-used hardware and software,...
Simulation of a maximum power point tracking (MPPT) algorithm prior to implementation is useful in avoiding unnecessary prototyping, fabricating and testing costs. Also upon implementation of the actual hardware system, performance monitoring and recording of the system behavior is of importance. The data manipulated above is useful in energy management and saving applications. To full fill the above...
Cyber Physical Systems (CPS) comprise the integration of embedded computer systems and the physical processes that these computer systems interact with. Examples of such systems stretch from small embedded devices, e.g., intelligent sensor systems, to larger and often complex industrial systems, e.g., industrial automation systems. These systems are not only subject to functional requirements, but...
Contradiction between the rapid expansion of WAN traffic demand and local area network export-bandwidth force the flow control nodes are deployed to the local area network key links. The article analysis of the traffic needs of network users. From the perspective of the LAN operations, described the principles and objectives of channel flow control that based on application layer the principle, designed...
By this paper, the background for the occurrence of the industrial control configuration software(CS) is analyzed, the connotation of CS is given, the architecture of it is constructed, and the current situation of CS is summarized. Finally, the six development trends of CS are predicted, they are: function customization, function extension, application expansion, monitor networking, software standardization...
This papers, directing at machinery manufacturing enterprises implementing order production and the problems existing in their fast and accurate cost accounting process relying on informatization, from the perspectives of cost accounting process and the integration of PDM and ERP, aims to propose an effective method which will bring about fast and accurate cost accounting. Additionally, this paper...
Natural language safety requirements in industrial standards pose risks for ambiguities which need to be resolved by the system manufacturer in concertation with the certificate authority. This is especially challenging for small and medium-sized enterprises (SME). In this paper we report on our experiences with applying traditional requirements engineering techniques, formal methods, and visual narratives...
The International Electrotechnical Commission (IEC) has defined the standard IEC 61499 for the next generation of distributed control systems used in agile manufacturing systems. This work identifies and characterizes different types of communications needed for distributed control. It simplifies application designers work and middleware implementation for the standard. Then, a proposal is presented...
This paper mainly deals with the data exchange by DDE technology between the higher engine system and site equipment. The system reads the data to Excel with realtime reports, or stores data to Access database, then generates history reports in flexible way with different inquire conditions. The role of communications protocol in monitoring and other applications is briefly introduced. By using VB...
