Current detection method

A current detection method includes the steps of: 1), initialization in which a data counter and a data accumulator are set to zero, and initial values of the counter and the accumulator are preset; 2) processing of current measuring data which includes concrete steps of: 2a) accumulation; 2b) judgment; 2c) data output; and 2d) update; and 3) outputting and zero setting of the updated data value, and returning. The method adaptively adjusts the length of a filter according to the size of a measured current, effectively weakens the noise influence and reduces measuring errors, and has a fast response speed to fast and large range variation of the measured current. At the same time, the data processing method provided by the invention can flexibly adjust parameters according to an actual detection condition and an instrument requirement. The calculation amount is small, and the resource occupancy is low. 一种电流检测方法，其步骤为：1）、初始化：检测数据、累加器置零，预设计数器与累加器的初始值；2）、对电流测量数据进行处理，具体步骤为：2a）、累加；2b）、判断；2c）、输出数据；2d）、更新；3）、将更新后的数据值
