以C8051F020為核心處理器，設(shè)計無線傳感器網(wǎng)絡(luò)數(shù)據(jù)采集系統(tǒng)。系統(tǒng)采用SZ05-ADV型無線通訊模塊組建Zigbee無線網(wǎng)絡(luò)，結(jié)合嵌入式系統(tǒng)的軟硬件技術(shù)，完成終端節(jié)點的8路傳感器信號的數(shù)據(jù)采集。現(xiàn)場8路信號通過前端處理后，分別送入C8051F020的12位A/D轉(zhuǎn)換器進行轉(zhuǎn)換。經(jīng)過精確處理、存儲后的現(xiàn)場數(shù)據(jù)，通過Zigbee無線網(wǎng)絡(luò)傳送到上位機，系統(tǒng)可達到汽車試驗中無線測試的目的。
Abstract:
This paper designs a wireless sensor network system for data acquisition with C8051F020 as core processors.The system used SZ05-ADV wireless communication module，set up a Zigbee wireless network， combined with hardware and software technologies of embedded systems，completed the end-node 8-locale sensor signal data acquisition.Eight locale signals were sent separately into the 12-bit ADC of C8051F020 for conversion through front treatment.After accurate processing and storage，the locale data was transmitted to the host computer through Zigbee wireless.The system achieves the purpose of wireless testing in vehicle trial.

Abstract:
In this paper,a top PC and AT89C52 under-bit microcontrollers from the main component of the tour distributed temperature detection system is presented. Master and slave can use RS-485 serial communication standards for communications.Based on next-bit machine for basic goods temperature detected data Tour, the top can achieve the integrated treatment of PC functions or for the expansion of long-distance operation. The entire inspection system is fast, expansion.
This book is the most accurate and up-to-date source of information the STL currently available. ... It has an approach and appeal of its own: it explains techniques for building data structures and algorithms on top of the STL, and in this way appreciates the STL for what it is - a framework. Angelika Langer, Independent Consultant and C++ Report Columnist "A superbly authored treatment of the STL......an excellent book which belongs in any serious C++ developer s library." Jim Armstrong, President 2112 F/X, Texas. \n
The C++ Standard Template Library (STL) represents a breakthrough in C++ programming techniques. With it, software developers can achieve vast improvements in the reliability of their software, and increase their own productivity.
This book is a hands-on introduction to the principles and
practice of embedded system design using the PIC microcontroller. Packed
with helpful examples and illustrations, it gives an in-depth treatment of
microcontroller design, programming in both assembly language and C, and
features advanced topics such as networking and real-time operating
systems. It is accompanied by a CD-ROM containing copies of all programs
and software tools used in the text and a `student version of the C
complier
Designing Embedded Systems with PIC Microcontrollers: Principles and
Applications is ideal for students of electronics, mechatronics and
computer engineering. Engineers in industry and informed hobbyists will
also find this book a valuable resource when designing and implementing
both simple and sophisticated embedded systems using the PIC
Microcontroller.
Visual Basic Shell Programming ventures where none have gone before by showing how to develop shell extensions that more closely integrate an application with the Windows shell, while at the same time providing an advanced tutorial-style treatment of COM programming with Visual Basic. Each major type of shell extension gets attention, including customized context menu handlers, per instance icons, and customized property sheets.
“This book is a tremendous achievement. You owe it to yourself to
have a copy on your shelf. The chapter on iostreams is the most
comprehensive and understandable treatment of that subject I’ve
seen to date.”
The use of FPGAs for cryptographic applications is highly attractive for a variety of reasons but at the same time there are many open issues related to the general security of FPGAs. This contribution attempts to provide a state-of-the-art description of this topic. First, the advantages of reconfigurable hardware for cryptographic applications are discussed from a systems perspective. Second, potential security problems of FPGAs are described in detail, followed by a proposal of a some countermeasure. Third, a list of open research problems is provided. Even though there have been many contributions dealing with the algorithmic
aspects of cryptographic schemes implemented on FPGAs, this contribution appears to be the first comprehensive treatment of system and security aspects.
