    摘要： Sheet handling and counting apparatus includes a control system having master and slave processors. The slave processor continuously examining passing sheets to measure sheet length and look for doubles. The slave processor generates outputs representative of jam, doubles error, length error and diagnostics as well as detecting the presence of a check separator for stopping the sheet handling and counting apparatus. The master processor controls the sheet apparatus in accordance with the status signals developed by the slave processor, as well as other data derived from sensors interfaced with the master processor. The master processor transmits a control word to the slave processor to control operation of the length measurement according to one of a plurality of selectable tolerances and to select one of a plurality of operating modes for detecting doubles. The slave processor transmits a multibit code word representing the result of the length, doubles and other evaluations for each sheet, the master processor controlling the apparatus in accordance with the evaluation data received from the slave processor. Adaptive techniques are utilized for both length measurement and doubles detection. The length measurement technique permits the accurate counting of sheets, even though they are skewed as they are fed through the apparatus.

    摘要翻译： 片材处理和计数装置包括具有主处理器和从属处理器的控制系统。 从属处理器连续检查通过的纸张以测量纸张长度并寻找双打。 从处理器产生代表卡纸，双重误差，长度误差和诊断的输出，以及检测是否存在用于停止片材处理和计数装置的检查分离器。 主处理器根据从处理器开发的状态信号以及从与主处理器接口的传感器得到的其他数据来控制纸张装置。 主处理器将控制字发送到从处理器，以根据多个可选公差中的一个来控制长度测量的操作，并且选择用于检测双精度的多个操作模式之一。 从处理器根据从从属处理器接收到的评估数据，发送表示每张纸张长度，双倍和其他评估结果的多位代码字，主处理器控制装置。 自适应技术用于长度测量和双重检测。 长度测量技术允许片材的精确计数，即使它们在通过设备馈送时它们是倾斜的。
