Control method and device for product package missing detection processing

The invention discloses a control method and device for product packet missing detection processing, and the method comprises the steps: obtaining detection data, carrying out the sampling of the detection data according to an external input synchronization signal, and generating an analog signal based on a product; the synchronizing signal is an output signal of the encoder based on the product displacement distance; comparing the analog signal with a pre-determined reference signal and outputting a packet missing type; and querying the rejecting machine position corresponding to the packet missing type, and performing rejecting operation on the detected product on the rejecting machine position. The device can accurately detect the packet missing condition of the cigarette cartons, classifies and rejects the cigarette cartons according to the packet missing type, and is convenient to rework and recycle. 本发明公开了一种产品缺包检测处理的控制方法及装置，方法包括获取探测数据，根据外部输入的同步信号对所述探测数据进行采样，生成基于产品的模拟信号；所述同步信号为编码器基于所述产品位移距离的输出信号；将所述模拟信号与
