Abstract

The invention relates to a multi-channel synchronous trigger control system. The system comprises an embedded master controller, a power management module and a data acquisition module, master control is carried out through a core controller adopting an ARM + FPGA processing mode, real-time data detection and instruction issuing of a microwave generation device are completed, and on the basis, monitoring control over the power management module and a vacuum set is achieved. The embedded control circuit board realizes the compact and high-integration requirements of the microwave source control system through a PS and PL cooperative working mode, in addition, the parallel processing mode of the FPGA at the PL end accelerates the processing speed of a large amount of data generated in the working process of the system, the large-capacity design of the PS end meets the data caching requirement in the real-time processing process of the FPGA, and the large-capacity design of the PS end meets the requirement of data caching in the real-time processing process of the FPGA. Therefore, the real-time performance of the control system is realized.

Description

technical field [0001] The present application relates to the technical field of power electronics, in particular to a multi-channel synchronous trigger control system. Background technique [0002] With the continuous improvement of the power capacity of high-power microwave sources, the control system, as an important part of the high-power microwave source system, needs to provide reliable trigger pulse excitation, and at the same time have high integration, real-time performance and high-power microwave environment adaptability Characteristics. In order to realize the real-time control of the high-power microwave source system, the control system should have the functions of process control, real-time acquisition and processing of pulse signals, etc. In addition, it should have electromagnetic compatibility design to meet its working requirements in the high-power microwave environment. [0003] In recent years, researchers have designed control systems for HPM source s...

Problems solved by technology

However, its capacity is too small to meet the data storage requirements of the system for real-time processing.

The author uses an external DRAM (Dynamic Random Access Memory, DRAM) to cache data. In the process of data processing, the access of the real-time processor to the DRAM will inevitably lead to a decrease in the speed of the system when processing data and a decrease in the integration of the system design.

[0004] In summary, although people have studied and designed the control system of the HPM source system, the existing solutions still cannot meet the requirements of high integration, system compactness, real-time data processing, and high-power microwave environment adaptability when the HPM system is working.
