Study on the relationship between redundancy design technique and reliability;

The application of redundancy design in PLC control system;

Necessity of software and hardware redundancy design for microprocessor based protection;

Photoelectric liquid level sensor based on redundant design;

The paper mainly discusses the method of improving the reliability of limiting speed braking for the servo system,briefly analyzes the principle and the common method of safety braking for the servo system,researches the process and rule of limiting speed braking for the servo system,and analyzes the necessity of redundant design for limiting speed braking.

A effective redundant design will be necessary when it is determined that a single component,subsystem or system may not be reliablie enough by the development testing and reliability analysis.

Research and Application of ARTiSAN Real-time Studio in the On-board TMR System of CBTC System;

Seamless Reconstruction Method for TMR Computer Based on Micro-package Protocol

In order to enhance the reliability of the SRAM based FPGAs,we have improved the typical TMR(Triple Module Redundance)technology,and designed a partial reconfiguration method which can be used for more than one reconfigurable areas and can tolerate more than one fault.

The development and accomplishment of a fault-tolerant multiprocessor system which adopted token technology based on general three-module redundancy are presented The critical techniques such as bus arbition,synochronize communication and voting mechanism are introduced,which are very valuable in practical application of some real-time control field requiring high speed and reliabilit

Research of Synchronization in Triple Modular Redundancy System;

This paper presents the implementation of a distributed triple modular redundancy control system including the choice of system CPU,the implementation of system communication network,system synchronization strategy and the design of TMR output voter.

a kind of repairable system model called triple modular redundancy with non-Markov process is presented, and after expounding work principles, soft and hardware structure, and fault-tolerant properties, reliability analysis for life span is made.
