Abstract
The invention is suitable for the technical field of embedded software, and relates to a periodic sine wave anti-interference method of a photovoltaic Bluetooth micro-circuit breaker, a medium and a terminal, and the method comprises the steps: S10, recording sampling points of a cyclic wave, and storing the sampling points in a cache array; s20, after the number of cycle sampling points is full, calculating an effective value according to the first peak value and recording a corresponding position offset; s30, recording sampling points of the next cycle and storing the sampling points in the cache array; s40, finding out a next crest value, and recording a position offset new; and S50, calculating the position deviation in the step S20 and the step S40, judging whether the position deviation is greater than an allowable deviation point number or not, if so, determining that the sampling value is an effective sampling value, otherwise, determining that the sampling value is an invalid value, and recording Err + + times. The method is simple in process and convenient to operate, and solves the problem that a traditional photovoltaic Bluetooth micro-circuit anti-interference method is poor in effect under the condition that the product structure space is not changed and hardware resources are not increased.
