Description

technical field [0001] The invention relates to a measurement method, in particular to a cluster control system and method for multi-dimensional synchronous high-speed measurement. Background technique [0002] With the development of modern industrial manufacturing technology and information technology, the requirements for using high-speed and high-precision measurement systems to achieve high-precision control have further increased. With the improvement of integrated circuit performance, more application platforms for high-speed and high-precision control are also provided. Nowadays, system equipment mostly uses distributed control methods and architectures to achieve multi-point control, which restricts high-speed data transmission and fast motion control measurement, thus directly limiting the improvement of the measurement sampling frequency of the system and improving the characteristic performance and production capacity of the equipment. have a major impact. The ...

Problems solved by technology

But its disadvantage is that the super frame structure must be defined first, and the synchronous transmission communication channel must be defined before the data frame can be transmitted, and it cannot transmit data to multiple frame receivers at the same time, which is a point-to-point broadcasting method

It uses the definition of multi-dimensional frame structure to realize the selection of transmission target and transmission mode. It is a data transmission communication method that selects broadcast at one point in series and selects reception at multiple points. It cannot perform multi-channel parallel data transmission control, which limits the efficiency of data transmission. improve

[0005] And in Chinese patent application No. 200510023859.5, what it adopts is one-point broadcasting, multi-point releasing data, multi-point receiving data method, has realized synchronous broadcast data collection, when needing a large number of channels to collect, because this broadcasting method is A multi-stage serial synchronous broadcast method that limits the frequency increase of measurement data acquisition and transmission
