An evaluation space for open architecture controllers 总被引:2,自引:0,他引:2
Chi Yonglin 《The International Journal of Advanced Manufacturing Technology》2005,26(4):351-358
Existing open architecture controllers have different architectures and methods for realization, but none of them have been generally accepted or been widely applied in industry. Moreover, there is little literature that analyzes and compares these different open architecture controllers synthetically. So this paper establishes an evaluation space for open architecture controllers, a new method to analyze and compare the different open architecture controllers. The evaluation space enables the full evaluation of the open architectures and can easily find the controller’s advantages and disadvantages. The evaluation space for open architecture controllers is a multidimensional space, whose dimensions can be categorized as the requirement dimensions and the architecture dimensions. The requirement dimensions define different requirements of the open architecture controllers, and the architecture dimensions define the different realization methods of open architecture controllers. Establishing the relationships between the requirement dimensions and the architecture dimensions, the evaluation space can calculate the degree to which the different architectures meet the requirements of open architecture controllers, and then the integrated evaluation of different open architecture controllers can be obtained. Several typical open architecture controllers, such as NGC, OSACA, OMAC and OSEC, are compared based on the evaluation space; some valuable conclusions have been drawn. 相似文献

Recently, the conventional controller of machine-tool has been increasingly replaced by the PC-based open architecture controller,
which is independent of the CNC vendor and on which it is possible to implement user-defined application programs. This paper
proposes CNC-implemented fault diagnosis and web-based remote services for machine-tool with open architecture CNC. The faults
of CNC machine-tool are defined as the operational faults occupied by over 70% of all faults. The operational faults are unpredictable
as they occur without any warning. Two diagnostic models, the switching function and the step switching function, were proposed
in order to diagnose faults efficiently. The faults were automatically diagnosed through the fault diagnosis system using
the two diagnostic models. A suitable interface environment between CNC and developed application modules was constructed
for the internal function of CNC. In addition, a suitable web environment was constructed for remote services. The web service
functions, such as remote monitoring and remote control, were implemented, and their operability was tested through the web.
The results obtained through this research could be a model of fault diagnosis and remote servicing for machine-tool with
open architecture CNC. 相似文献
