机床电气化系统设计与友好界面的编程开发

This paper describes the research that has been carried out to date and the tools and methods which are currently being used and developed to assist the engineer in determining the residual stress distribution in welded components as required by assessment procedures such as BS7910, R6 and FITNET. 567An overview of instrumentation and control systems of a Korea standard nuclear power plant: A signal interface standpoint

This paper presents an overview of instrumentation and control (I&C) systems of a pressurized water reactor (PWR) type nuclear power plant (NPP) in Korea. Yonggwang unit 3, which was constructed as a basis model for a Korea standard nuclear power plant (KSNP), is selected as an example for the

presentation. This overview is derived from analyzing the I&C systems based on a top-down approach. The I&C systems consist of 30 systems. The 183 I&C cabinets are also analyzed and mapped to the systems. The overview is focused on an interface between the systems and the cabinets. This

information will be used to understand the implementation of the I&C systems and to group the systems for an upgrade.

PLC-based system for oil rig control

One of the more challenging applications for a pump is the hazardous conditions on an oil rig out at sea.

A European oil and gas equipment manufacturer ensured that pump operators were safe by using a range of Bosch Rexroth products to remotely control its diesel engine-driven pumps.

Design and implementation of the BESIII detector-control system

In the upgrade project of the Beijing Electron-Positron Collider (BEPCII), a novel Detector-Control

System (DCS) for the Beijing Spectrometer (BESIII) has been built and started its successful operation for the BESIII Commissioning. The main task of the DCS is to monitor and control the status of the BESIII detector and to guarantee a safe operation of the detector. The DCS must provide a uniform and

coherent interface to detector operators even though there are a large number of distributed I/O channels from a large variety of equipments. For this reason, the DCS is hierarchically organized and divided into three layers: front-end layer (FEL), local control layer (LCL) and global control layer (GCL). In the FEL, devices ranging from simple sensors up to complex computer-based devices like embedded systems
