| This paper is concerned with fault diagnosis and tolerance in microcomputer extended interface technology. Based on a few hardware redundancy, software redundancy, information redundancy or time redundaney are mainly applied. With the aid of artifical intelligence, it could be realized fault diagnosis automatically dynamically and fault toleranted in microcomputer extended interface. In this paper, an intelligent fault diagnos is and a fault tolerant method to micrcomputer interfaces and connected devices is... This paper is concerned with fault diagnosis and tolerance in microcomputer extended interface technology. Based on a few hardware redundancy, software redundancy, information redundancy or time redundaney are mainly applied. With the aid of artifical intelligence, it could be realized fault diagnosis automatically dynamically and fault toleranted in microcomputer extended interface. In this paper, an intelligent fault diagnos is and a fault tolerant method to micrcomputer interfaces and connected devices is put forward, A fault diagnosis expert system structure to a small parallel port fault model is discussed. | 本文阐述了在极少考虑硬件冗余的前提下,采用信息冗余、软件冗余及时间冗余的方式,借助人工智能工具,实现在微机扩展接口上,对运行中的故障动态自动诊断并容错的方法。 | This paper expounds computer error-avoidance, error-correction,error-allowance technology,and from this probes into the method of improving computer system stability and relialbility by using hardware and/or software redundancy. | 通过对计算机避错、纠错、容错技巧的论述 ,探讨了可以使用硬件、软件冗余手段来提高计算机系统的稳定性和可靠性的方法。 | Because of the deterioration of the industry circumstance,there are lots of interaction,which make the hardware of the single-chip microcomputer system can't meet the demands of the industry circumstance.Then people pay more attention to antidisturbance by software,for its reliability,stability,function diversity,dexterity,it can make up the shortcoming of the hardware.Introduced the based requirement to insure the reliability of the single-chip microcomputer system, and based on this,expounds some methodology... Because of the deterioration of the industry circumstance,there are lots of interaction,which make the hardware of the single-chip microcomputer system can't meet the demands of the industry circumstance.Then people pay more attention to antidisturbance by software,for its reliability,stability,function diversity,dexterity,it can make up the shortcoming of the hardware.Introduced the based requirement to insure the reliability of the single-chip microcomputer system, and based on this,expounds some methodology to the reliability such as procedure device, endure fault on software, recovery and so on. | 由于现场工业环境的恶化,存在着大量的干扰源,使单片机控制系统在硬件上无法满足工业环境要求,因此,软件抗干扰技术越来越引起人们的重视。采用软件抗干扰不需增加硬件设备、可靠性高、稳定性好、功能多样、使用灵活,可在一定程度上实现"以软补硬"。文章论述了多种软件抗干扰方法,如"结构化程序设计"、"软件冗余"、"软件拦截"、"程序失控恢复"等,来提高单片机应用系统的可靠性。 |   | << 更多相关文摘 |
