Description

technical field [0001] The invention relates to a signal collection and processing early warning device, in particular to a cable multi-parameter signal collection and processing early warning device, in particular to a data collection and processing core module of a cable comprehensive monitoring system. The invention belongs to the field of electronic equipment design. Background technique [0002] The cable comprehensive detection and early warning system needs to collect the leakage current of the three phases A, B, and C in the frequency range from power frequency to high frequency. Because some high-frequency components in the leakage current are burst pulses, seamless collection is required to ensure 100% collection. The system uses 100M sampling rate for high-frequency signals, AD resolution 12bit, A, B, C three-phase synchronization Acquisition generates 3.6Gbit data per second. If all the data is processed by the microprocessor, the system pressure is very high, a...

Because some high-frequency components in the leakage current are burst pulses, seamless collection is required to ensure 100% collection. The system uses 100M sampling rate for high-frequency signals, AD resolution 12bit, A, B, C three-phase synchronization Acquisition generates 3.6Gbit data per second. If the data is all processed by the microprocessor, the system pressure is very high, and because the microprocessor is a serial processing structure, it is very difficult to expand the channel later

There is no effective solution to the problem of seamless high-speed data acquisition and processing in the comprehensive cable detection and early warning system.
