Abstract: A web based remote monitor & control system for grinding process is presented. In this
system, OPC/Socket drive technology, CAN bus technology, B/S structure, Java Applet and ActiveX
etc. are used to realize the remote monitor & control, and grinding processes in different place can be
monitored and controlled by remote grinding expert only through browser, so it overcomes the
shortage that the grinding quality depends on skilled workers and variants with grinding operators.
The data processing and feature releasing method of AE signals in grinding process also be discussed.
The grinding state feature information can be updated automatically, and be browsed by remote
experts through running the ActiveX in the browser. Therefore, it is of important significance for
improving workers’ working environment and work-piece quality.
Abstract: Agent technology is widely employed to construct dynamic, distributed collaborative
manufacturing systems in which the individual participating agents contribute to execute different
part of the whole manufacturing job, and the final goal is achieved through cooperation. However,
the cooperation among agents is based on message exchange, and the system requires additional
process control and management mechanism to ensure the operation according to a pre-defined
process model. This paper defines the collaborative manufacturing job and related information in
domain knowledge model, and applies knowledge based expert system to build software agents for
process scheduling and management. The system architecture, components and the implementation
methods are discussed. A prototype system is constructed on the basis of JADE agent framework
and Jess rule engine and demonstrated with an industry product as a case study.
Abstract: Complicated product lifecycle information including design and manufacturing, operation
and maintenance as well as relative supply information, all are tightly related to the product life cycle
cooperative design and the process of establishing the dynamic alliance. Data grid includes the digital
library and data grid service technologies and it can provide the reliable technique support to
integrated information systems. The grey clustering is used to merge the same type of factors based on
presetting conditions. The improved grey clustering algorithm has been used to find the main failure
types for some equipment. The structure of the multi layers and cross information share in the
dynamic alliance for the ship life cycle information based on two data grid service centers and the
flows of resources and information discovery based on data mining are proposed according to the
information share requirements. A developed protocol system based on two data grid services has
been presented to show ship lifecycle information share and finding the main failure types of pumps
using grey clustering algorithm.

well as some effects acquired.
Abstract: This paper established the framework of the decision-making model system for
autonomous vehicles. Based on virtual reality environment modeling technology, the virtual scene
was obtained. The driving performance of autonomous vehicles in real environment was simulated
with that of the virtual vehicle in virtual environment. It was studied the influence of driver’s
aggressiveness on lane-changed performance through considering human factors, and several
longitudinal driving modes were classified and discussed. Three-power B spline function was used
in this paper to plan path by interpolating characteristics points. The driving framework and the
driving models described in this paper serve to address the problem of building more realistic traffic
at the microscopic level in driving simulators. The autonomous vehicles based on this system can be
used as the vehicles in simulators and help to design traffic or help to verify the performance of
Abstract: Measurement of the grinding wheel topography and its change in machining process is
important for revealing the grinding principle of high-temperature brazed mono-layer
super-abrasive grinding wheel. A new approach of measuring grinding wheel topography based on
binocular stereovision is presented. Firstly, the binocular images are achieved while the optical axes
of the two cameras are parallel, and a corner reflection function algorithm is applied to detect
corners. Secondly, in order to get matching corners, optimal matching template is obtained by
matching curves. The experimental results show that the sequential similarity matching operation
with optimal template has advantages of high accuracy, and less error matching. Finally, the height
of the corners is obtained by calculating their parallax on left and right image, and the height error
is less than 5%.
Abstract: A new model description was proposed which is divided into heavy and light model for
reducing the pressure of the network transfer which is constructed by XML files. The model
description includes the production assembly tree information, part feature information and
geometry information. So it can satisfy the request of browse, query, and annotation with the model.
At the same time, model description is compressed by several methods which avoid the designers
from the long time waiting.
Abstract: This paper is focused on using the method of computer technology combined with the
knowledge of experts to determine heavy-duty cutting processing parameters according to the
relevant theories of metal cutting. This “Expert System of the Parameter Optimization in the
Heavy-duty Cutting Processing” is based on the VC++6.0 programming language and SQL Sever
2000. It is divided into two subsystems, turning and milling machining. Taking the turning machining
subsystem for example, by using methods of generating expression combined with frame
representation, this paper classifies and generalizes related knowledge, and combines the knowledge
base with the data base to set up the knowledge base of the subsystem. Also this paper introduces the
process of inferential mechanism of the optimizing modules of cutters and machining engagements.
Abstract: This paper presents an innovative product design system based on Quality Function
Development (QFD) and Theory of Inventive Problem Solving (TRIZ in Russian abbreviation).
House of Quality (HOQ) is the core of QFD. To make QFD more practical and operable for small
and medium-sized companies, a simplified model of HOQ is proposed. A set of reasoning scheme
for inferring requirements relationships is adopted to facilitate constructing the HOQ. The
contradiction in the process of mechanical design is defined by TRIZ as physical contradiction and
technical contradiction. These two contradictions are solved through contradiction matrix and
inventive principles of TRIZ. The innovative design system mainly uses the tool of contradiction
matrix to solve the bottle techniques attained from QFD. By taking the HOQ as its interface the
integration between QFD and TRIZ is realized. After conducting quality function development, two
outputs can be obtained. They are the technical measure needing improvement and the technical
measure that is getting worse while improving the former one. These two measures are taken as
inputs of TRIZ module to analyze and solve the problem of product design.
Abstract: In this paper COM+ based on Microsoft .NET is adopted to realize a Distributed
Collaborative System (DCS). This system adopts a complex architecture combined C/S with B/S to
reduce the remote communication and improve the performance. By means of IE or other browsers, a
client can download client tool, register or login, search or publish information via the collaborative
website. After installing the client tool, a client can automatically receive the collaborative requests or
invitations from the collaborative server and collaborate with other participators. The system utilizes
COM+ services to realize the Distributed Synchronous Communication (DSC) and Distributed
Asynchronous Communication (DAC). Loosely Coupled Event (LCE) service can make DSC true
easily and effectively. Transaction service, Queued Component (QC) service and Windows NT
Service can be applied to realize DAC efficiently and reliably.
