The invention discloses application of fingerprint identification to control starting and stopping of charging of a charging pile. A switching signal is output through a fingerprint module: charging is started successfully when fingerprint identification is performed once, and charging is paused, interrupted or ended successfully when fingerprint identification is performed again; performing signal identification before the charging pile is started; information query is carried out through fingerprints in the charging process; and charging pause, interruption or charging ending is realized through fingerprint identification. According to the invention, the charging pile is controlled to start and stop charging through fingerprints; the non-linear adaptive filter is used for removing a black area around the white points and an isolated area around the black points to guarantee the uniformity of fingerprint line amplitude; the filtering is realized by combining a linear filter and an intermediate value nonlinear filter; the problem that many false characteristic quantities appear in the prior art is solved; and the problem that the place connected with the fingerprint is broken is also solved.

    本发明公开了一种指纹识别用于控制充电桩启动和停止充电的运用,通过指纹模块输出开关信号:一次识别指纹成功启动充电,再次识别指纹成功暂停、中断或结束充电;充电桩启动前信号识别;充电过程通过指纹进行信息查询;通过指纹识别实现充电暂停、中断或结束充电。本发明,通过指纹控制充电桩启动和停止充电;非线性适配滤波器:去除白点周围的黑色区域和黑点周围的孤立区域,保障指纹线幅的均一性;滤波是结合线性滤波器和中间值非线性滤波器实现的;解决了现有技术中出现许多假特征量的问题;也解决了指纹连着的地方被断裂的的问题。
