[Software Engineering] ydbshujucaiji DL : 0: 数据采集系统：（1）采用定时中断和软件控制的方法，实现每隔N秒（N可设置）实现对模拟量的采集。（2）根据预先设置的数值和采集的模拟量决定控制输出。如假设控制中心值为2.0V，当输入值超过2.0±0.2(V)时，模拟控制步进电机转：正偏差时反转，负偏差时正转；当输入值超过2.0±0.5(V)时，进行上、下限报警。（3）对采集的值应进行数字滤波，如可一次采集10个值，去掉最大值、最小值，然后取平均值。（4）实现8路采集，不同路的中心值及上、下限等参数可灵活设置。 -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.
