An expandable multi-modal tomography system

Abstract

The present invention relates to a modal-expandable tomography system, comprising a master control module and each single-modal tomography module. The master control module undertakes the data communication function between the single-modal tomography modules, and coordinates the data acquisition speed and timing sequence of each single-modal tomography module. The single-modal tomography modulescan be connected to a multi-modal control line through a multi-modal communication interface. The multi-modal control line is adopted to connect the multi-modal master control chip and control chips of the single-modal tomography modules. Through transmitting state and command signals through the multi-modal control line, the multi-modal master control chip controls the working time sequence and working speeds of the single-modal tomography modules and coordinates data communication of among the modals. The multi-modal master control chip adopts an FPGA chip. The level value on the state lineis read, a work starting command is sent to each modal through a command line according to the programmed internal program, and the working time sequence of the single-modal tomography modules is coordinated.

Description

technical field [0001] The invention belongs to the technical field of measurement, and relates to a multi-mode tomographic imaging system with expandable modes, 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 well as in biolog...

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
