Description: Data acquisition system: (1) Use timer interrupt and software control, to achieve every N seconds (N can be set) of analogue collection. (2) According to the pre-set values and the decision to control the analog output. Assuming control center value of 2.0V, when the input exceeds 2.0 ± 0.2 (V), the analog control stepper motor turn: deviation is reversed, the negative deviation is transferred when the input exceeds 2.0 ± 0.5 (V) When carried out, the lower limit alarm. (3) the value of the collection should be digital filter, such as a collection of 10 value can, remove the maximum, minimum, and then averaged. (4) to achieve 8 collection, the center of value and different way, the lower limit and other parameters can be flexibly set.
