In this paper, the ARM embedded fire alarm controller is designed and applied to the fire intelligent video surveillance system of large space. Based on the Modbus communication protocol, the fire alarm controller receive the information from video surveillance platform, sending out alarm signal of voice and light when fire happened, and then the fire sprinkler system are controlled to extinguish...
Design of on-line embedded web server is a challenging part of many embedded and real time data acquisition and control system applications. The World Wide Web is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billion of users worldwide and allows the user to interface many real time embedded applications like data acquisition, Industrial...
FlexRay is a popular communication protocol in modern automotive systems with several computation nodes and communication units. The complex temporal behavior of such systems depends highly on the FlexRay configuration and influences the performance of running control applications. In our previous work, we presented a design framework for integrated scheduling and design of embedded control applications,...
This paper deals with distributed multiagent reconfigurable embedded-control systems following the component-based International Industrial Standard IEC61499 in which a function block (FB) is an event-triggered software component owning data and a control application is a distributed network of FBs. We define an architecture of reconfigurable multiagent systems, where a reconfiguration agent modeled...
Spring sorting system is the most important equipment of quality inspection in valve spring automatic production line. Based on embedded technology, a new spring sorting system composed of multiple controllers has been designed. In the system, each controller managed its related services, worked in parallel and coordinated through CAN-bus communication to ensure the system speed. The system defined...
Interrupt response mechanism and the stream interface driver model of Windows CE 5.0 are introduced. In view of high real-time requirements of NC (numerical control) system, the way how to realize the real-time control of embedded NC system is elaborated from the interrupt disposal process of Windows CE. Stream interface driver is adopted to develop the driver of S3C2440A processor's timer and the...
This study aims to develop a remote pool control system over the Internet. Modtronix SBC68EC card is used in the system as embedded web server connected between the Internet and the pool control card. The system is accessible by a computer wherever the Internet connectivity is possible. The user (computer) communicates with the microcontroller over the Internet through the HTTP protocol via the web...
The paper designs a home network measurement and control system based on AT91SAM9260. It takes AT91SAM9260 as control center, boots embedded Linux kernel image file by Uboot, and construct embedded WebServer by technology of embedded. Users could not only implement remote control and check work status information of electrical equipment, but also monitor security of family through Internet. There...
Many application systems maintain state as part of their behavioral semantics. This state can reflect continuous state, e.g., sensor measurements, or discrete state. Modeling notations like Simulink combine the two to support modeling of hybrid control systems. In this paper we examine whether the intended behavior of state-based systems is implemented correctly by different runtime architectures...
The application development of embedded display terminal based on ARM microprocessor is studied, by applying 32 bit RISC key microprocessor technique, embedded software technology, embedded GUI (graphics user interface) technology, CAN bus communication technology, information storage and management technology etc.. The design of embedded hardware platform, of which the core is S3C2410CPU, is completed...
Based on client-server architecture, this paper proposes the design and implementation of system controlling embedded Linux downloading server. The software architecture design of this system is composed of three parts: network layer, control layer, and application layer, which is modular and pluggable. The implementation also proved the feasibility, reliability and portability of this design.
The factory of the future is the wireless factory-fully programmable, nimble and adaptive to planned mode changes and unplanned faults. Today automotive assembly lines loose over $22,000 per minute of downtime. The systems are rigid, difficult to maintain, operate and diagnose. Our goal is to demonstrate the initial architecture and protocols for all-wireless factory control automation. Embedded wireless...
