基于MODBUS协议的激光雕刻切割系统HMI人机交互设备

近年来,国内激光雕刻切割控制器技术发展迅速,基于PC的传统控制器已相当成熟.为了显著提高工业生产效率,适应工业生产规模扩张的需要以及工业对系统稳定性要求的提高,目前国内几家专业运动控制器厂家已经实现了激光雕刻切割控制器的完全脱机运行.本文针对脱机控制器的需要设计一款人机交互设备,该设备采用AT89C55WD单片机为主控制器,采用标准的MODBUS协议实现HMI与脱机控制器的可靠通讯.     

Quality of Service in VoIP Communication

The focus of this paper lies in the practical aspects of voice over IP communication. VoIP configurations in the H.323 standard will be presented briefly. Following that, the fundamental protocol procedure of H.323 communication will be briefly explained. A further part of the paper will address the subject QoS (quality of service), and present the common measurement methods used in QoS. Results gained from experiments conducted in a VoIP environment will then follow. The investigations concentrate primarily on the load behavior of voice packets in relation to important parameters of this service. The results obtained are presented and evaluated in diagrams. The paper concludes with a summary.

Comparison of two models for managing reliability growth during product design

Relying on reliability growth testing to improve system designis neither usually effective nor efficient. Instead it is importantto design in reliability. This requires models to estimate reliabilitygrowth in the design that can be used to assess whether goalreliability will be achieved within the target timescale forthe design process. Many models have been developed for analysisof reliability growth on test, but there has been much lessattention given to reliability growth in design. This paperdescribes and compares two models: one motivated by the practicalengineering process; the other by extending the reasoning ofstatistical reliability growth modelling. Both models are referencedin the recently revised edition of international standard IEC61164. However, there has been no reported evaluation of theirproperties. Therefore, this paper explores the commonalitiesand differences between these models through an assessment oftheir logic and their application to an industrial example.Recommendations are given for the use of reliability growthmodels to aid management of the design process and to informproduct development.
