Online monitoring system of switch equipment based on DSP (Digital Signal Processor) and FPGA (Field Programmable Gate Array)

Abstract

The invention discloses an online monitoring system of switch equipment based on a DSP (Digital Signal Processor) and an FPGA (Field Programmable Gate Array). The online monitoring system comprises an analogue signal conditioning module, an A / D (Analogue / Digital) conversion module, an FPGA data acquisition module, a reserved channel, a DSP module, a serial-to-parallel module and a communication module, wherein the analogue signal conditioning module, the A / D conversion module, the FPGA data acquisition module, the DSP module and the communication module are connected in sequence; and the serial-to-parallel module is connected to the DSP module. By utilizing the FPGA and the DSP, accessing, judging, processing, packaging and reporting of data are realized, therefore, the operation speed is high, and the real-time requirement for monitoring a power system is satisfied; the FPGA and the DSP are operated independently, the advantages of both the FPGA and the DSP are played, and information interaction is realized through a data bus, an address bus and a control line, so that functions of the whole system are completed; and analogue signals and digital signals are processed separately, therefore, interference of the analogue signals on the digital signals is avoided, and the reliability for data acquisition is increased.

Description

technical field [0001] The invention belongs to the technical field of real-time data collection and processing, in particular to an on-line monitoring system for switchgear based on DSP and FPGA. Background technique [0002] Data acquisition and processing technology is an important branch of information science, which studies the technology in the process of information data acquisition, storage, processing and control. Today, when computers are widely used, data acquisition has very important applications in many fields, and it is a bridge connecting computers with the external physical world. Especially in the environment that requires high real-time information or harsh environment, the necessity of its application is more prominent. As the application range of data acquisition and processing technology becomes wider and wider, more and more types of signal sources are involved, and the collected data are various physical quantities that have been converted into elect...

AI Technical Summary

Problems solved by technology

Due to the current switch on-line monitoring system using a single processor, the amount of collected signals and processing speed are limited, and a high-performance CPU is required to complete a huge amount of data processing algorithm. New projects need to redesign the system, which cannot be expanded, and there are problems with the device. Complete equipment needs to be replaced
