A screw dismantlement machine is special equipment used in the ammunition assembling operation line. The control system of the machine should have high reliability and safety. A master-slave distributing structure (The IPC+PLC structure) is proposed for a control system. Industrial control computer is in charge of the management of resources, assignment and control of slave machine, real-time communication, and the implementation of interactive action functions. PLC is in charge of the motion control of the machine, and standard modules are adopted in the configurations of the system. A redundancy design technique was used. All of the devices of the system were set reasonably in the design process. In the aspect of software-design, many measures were adopted to ensure the reliability of the machine. The control system showed a degree of high reliability that meets the requirement of screw dismantlement machine.

某轻轨桥墩局部混凝土不合格,经加固方案比较后决定采用置换混凝土加固法.由于被置换混凝土部位的结构荷栽较大,为确保桥墩上部结构和施工操作的安全,在置换混凝土加固过程中采用计算机控制系统通过应变测试仪和粘贴在支撑结构及被置换结构或构件表面的应变片连接,在卸载过程中采用机械式千斤顶对结构施加顶升力时,结构发生的应变通过应变片传输到计算机控制系统,能准确地反映被置换混凝土部位结构的内力、结构的变形、结构的残余变形、支撑结构的内力等,从而使操作者了解到结构的真实受力状态.采用千分表监控结构位移,为卸载提供可靠的依据,最终达到结构卸载的目的.该工程在置换混凝土加固轻轨桥墩施工时加入了应变测试仪和计算机控制装置进行结构卸载,保障了轻轨桥墩在置换混凝土加固施工过程中结构和操作人员的安全.

CAN bus is one kind of serial communication bus which support distributed control and real time control effectively. In this paper, an intelligent fire alarm system based on CAN fieldbus technology and multi-single-chip-computer communication system is introduced. CAN (controller area network) is a fast serial bus that is designed to provide an efficient, reliable and economical link between fire detect sensors and fire control actuator. some intelligent algorithm or methods are adopted in the system to solve these problems, which miss alarm and error alarm are two difficult problems in the current fire alarm system. By use of the new technology of CAN fieldbus and single-chip-computer technology, Hardware circuit and software design for intelligent node SJA1000 based on CAN and fire detector are given. The designs of structure for network, parameter assignments for network and communication protocols are described in detail.

IEEE INDUSTRY APPLICATIONS MAGAZINE 2006年第2期12卷 21-28页

作者： Jacobs, R Regis, S Calif Portland Cement Co Glendora CA 91741 USA

Increasing production and quality demands in the cement industry have resulted in the need for improvement in the speed and accuracy of quality-control results. This need has been addressed many technological advances in quality-control automation in recent years. Two distinct methods of sampling and analysis, in-situ and extractive, have gradually developed. In-situ analysis occurs in the field at the process equipment, with the results transmitted through a computer control system. This article discusses the characteristics and differences in analyzer and control technologies that utilize the two different methods of obtaining a result.

A communication interface controlled by eye movements and voluntary eye blink has been developed for disabled individuals who have motor paralysis and therefore cannot speak. Horizontal and vertical electro-oculograms were measured using two surface electrodes referring to an earlobe electrode. Four directional cursor movements and one selection were realized by logically combining the detected two channel signals. Virtual input experiments were conducted on a virtual screen keyboard. Its usability and accuracy were improved using our proposed method.
