Embodiment Construction
[0016] The system analyzes the measured signal components, and the micro-current signal extraction module uses high-precision resistance sampling signals to convert current signals into voltage signals for easy extraction. Perform primary amplification, analog filtering and secondary amplification on the converted signal to complete the analog signal pre-conditioning. Considering that the signal contains many noise signals, a 5th-order Butterworth low-pass filter is used to filter out all signals higher than 3HZ. This system chooses MAX7410 chip to realize its function very well. After the filtered signal is amplified twice, the output is A / D converted, and the analog signal is converted into a digital signal, which is convenient for subsequent data processing. This system uses the MAX132 chip, which can realize 18-bit high-precision A / D conversion. Suppress 50HZ power frequency interference, and then go through range processing and MCU digital signal processing, mainly digita...
