By adopting embedded system, the wellhead remote control equipment is designed by choosing an ARM processor and RF2401. In the processing that Wireless transmission to achieve petroleum logging the data of communication between the wellhead, winches, ground equipment vehicles, or other data acquisition devices, so the operation of the downhole tool can be grasped by wellhead staff timely and accurate,...
In recent years, with advance in wireless communication technology, sensing technology, micro-electronics technology and embedded system, wireless sensor network (WSN) can be used for various application areas, such as home health care, military and industry. The localization service which provides the location information of mobile user is one of important service provided by WSN, because many applications...
Compare with the traditional food enterprise management mode, wireless self-service ordering management information system realizes the intellectualized and informationlizated restaurant management. We design a self-service ordering node including its software and hardware. The touch screen displays the taste and prices of the food for customers to input their orders directly by touching. The system...

Today's wirelessly networked embedded systems underlie a vast array of electronic devices, performing computation,communication, and input/output. A major design goal of these systems is energy efficiency. To achieve this goal, these systems are based on processors with numerous power and clock domains, variable clock rates, voltage scaling, and multiple hibernation states. These processors are designed...
Virtual machines (VMs) play an important role in mainstream computing by enabling interoperability, security, and higher levels of abstraction. Their use in embedded computing systems is deterred primarily by the resource constraints of embedded microcontrollers. In this paper, we show how various optimizations can significantly decrease these overheads, making VMs viable as system software for even...
The Cooperating Objects NETwork of Excellence (CONET) aims at building a strong community in the area of Cooperating Objects capable of conducting the needed research to achieve, in the long run, the vision of Mark Weiser for ubiquitous computing. For this purpose, research clusters have been instantiated covering, among other topics, scalable data processing, cooperation of mobile objects, simulations...
In response to the complexity of the cable, the occurrence of accidents and completing the task without cables in industrial field, an embedded Bluetooth data acquisition system which was combined with Bluetooth wireless-networking communication technicalness and data acquisition technicalness, based on LPC2142 and bluethooth chip called Rok101008 is designed to reduce cable connection.The major difference...
Designing and implementing operating system for wireless embedded systems powered by energy harvesters is a challenging task. Conventional operating systems require lot of system resources thus they are not applicable to these highly energy constrained devices. This paper discusses the requirements, design challenges, architecture of an operating system for energy autarkic wireless embedded systems...
Sensor network is an important technology in the domain of information technology application. Based on the embedded system and the transmission network bus, this paper offers the system structure and the testing flow of an evaluation system for the design structure of sensor network. The software and hardware of the evaluation system could be modulated based on user's requirement. The structure and...
In this paper we present preliminary results regarding data processing approach to energy efficiency of wireless and untethered field programmable gate array (FPGA)-based embedded systems. Re-configurability of FPGA allows for significant flexibility in its applications to embedded systems. However, high power consumption (caused by such flexibility) influences the designing process significantly...
This paper describes the radio-communications ldquostate-of-the-artrdquo and ldquostate-of-the-practicerdquo for interfacing nodes in an ambient intelligence network. We also discuss the role of software defined hardware for software defined radios that form the radio-communication interface for ambient intelligence networks. Nodes must be capable of communication over at least one medium from Wibree-like...
