Scalable multimodal tomography system based on cpci bus

Abstract

The present invention relates to a scalable multimodal tomographic imaging system based on CPCI bus, which mainly includes a multimodal control bus based on CPCI, a main control module and each single-modal tomographic imaging module, wherein the CPCI-based The multi-modal control bus undertakes the data communication function between different single-modal tomography modules, and coordinates the data acquisition speed and timing of different single-mode tomographic imaging modules; the multi-modal control bus based on CPCI realizes real-time system status Control output and real-time feedback; status lines and command lines always appear in pairs; the function of the multi-mode main control chip is to read the level value of the status line, according to the programmed program inside the chip, through the command line to the Each mode sends a start work command, coordinates the work sequence of each single-mode tomography module, realizes through the finite state machine, and proceeds sequentially according to the preset state transition diagram; each single-mode tomography module has a unified mode The modal communication interface includes N status lines, N instruction lines and a set of data lines when the system has N modalities.

Description

technical field [0001] The invention belongs to the technical field of measurement, and relates to a mode-expandable multi-mode tomographic imaging system based on a CPCI bus, which can realize free combination and expansion of different tomographic imaging modes. The present invention takes the multimodal tomography system as the description object, but it is not limited to this application. In other industrial processes and chemical reactions, in the measurement and control systems that coordinate the work of various detection modalities, the main idea of ​​the present invention is The control module and control method are still applicable. [0002] technical background [0003] Tomography technology has the characteristics of non-disturbance and visualization, which can realize the detection of complex flow medium distribution parameters, visual testing and monitoring of multiphase flow processes in petroleum, chemical, metallurgy, power, energy and other industrial fields...

AI Technical Summary

Problems solved by technology

One is that it can only be applied to a specific measured medium. Once the measured medium changes, or the sensitive field distribution parameters of the measured medium change, the original multi-modal system may not be applicable.

The second is that the modality cannot be flexibly expanded and any combination of multiple modalities can be achieved. If you want to obtain more modality information, you can only redesign the multimodal tomography system
