Considering the current situation of the hardware platform of domestic numerical control device has an insufficient safety performance and lack of effective quantitative evaluation method, this paper analyzes the requirements of hardware function safety of domestic CNC system and come up with a numerical control device hardware platform failure assessment(More)
In this paper, a repairable ability of triple modular redundancy TMR system was presented. There were two sets of processing units, which were set up in each module of TMR system. When one of modules in the TMR system was failure, the backup processing unit could be activated and the TMR system was reconstructed. Through analysis and testing, the method,(More)
In this paper, the jitter correction method based on Markov chain model was achieved for Numerical Control Field-bus. To improve the accuracy of numerical control field-bus synchronization, transformation delays were sampled to obtain the state transition matrix. The mean of estimated values were accumulated based on Markov prediction estimates method. And(More)
In order to meet the demand of CNC system based on function safety, this article analyzes software design of CNC system based on function safety and a safety components sharing mechanism is proposed. At the same time, a method of security threshold distribution for software of CNC system is presented. This method establishes the system structure model of(More)
With the extensive application of industrial sensor networks in the embedded field, the interconnection communication between the embedded node is proposed for the cross-LAN/WAN communication needs. Traditional communication schemes using proprietary protocols and sink nodes do not fully meet the interoperability needs. Web Services technology has the(More)
