Design an intelligent data acquisition and voltage monitoring system, the system microcontroller core and has the following features: 1) changes in the range of 2-4v analog signal (analog signal peak pulse interference and 50Hz frequency continuous sampling interference) and real-time digital display, the sampling period of 1 second, save the last 50 consecutive sampled values 2) when the sampled value is less than 2v when an alarm light flashing, greater than 4v When two alarm lights flashing 3) presence of systematic error correction of the linear interpolation 4) and PC serial communication at any time in accordance with the requirements of the host computer, upload the sample data 5) to produce a 10 duty cycle a 100Hz pulse wave amplitude 5v the peripherals.
