A scalable multimodal tomography system based on CPCI bus

Abstract

The invention relates to an expandable multimodal tomography system based on a CPCI bus, which mainly includes a multimodal control bus based on CPCI, a main control module and each monomodal tomography module. The multimodal control bus based on CPCI is responsible for data communication between different monomodal tomography modules, and coordinates the data acquisition speed and timing of different monomodal tomography modules. The multi-modal control bus based on CPCI realizes real-time control output and feedback of system state. State lines and command lines always appear in pairs. The function of the multimodal master control chip is to read the level value on the state line, according to the programmed program inside the chip, send the start working instruction to each mode throughthe instruction line, coordinate the working time sequence of each single mode tomography module, realize by the finite state machine, and carry out sequentially according to the preset state transition diagram. Each single-mode tomography module has a unified modal communication interface. When the system has N modes, the system contains N state lines, N command lines and a group of data lines.

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. technical background [0002] 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, as wel...

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
