At the same time, considering the jumpiness or incline caused inaccuracy and pretermission when the capsule moving ahead, two couples of infrared ray and electron transducer were designed to detect the light signal of the corresponding parts of the capsule. After the addition operation compensation and differential coefficient, turning the little different simulation signals of the body and cap of the capsule into digital signals for detection. It is more accurate for detection and stable to the disturbance. Step electromotor was used for the capsules direction turning which solved this problem efficiently. The capsules were ranged in order according to their colors with the cap at the same direction.

同时考虑到胶囊行进过程中跳动、倾斜及随机干扰造成的误判、漏判，设计了两对红外光电传感器用以同时检测胶囊上下两个边缘部位的光信号，两个检测信号经加法运算补偿、微分运算处理，将体现胶囊的帽、体微小几何尺寸差别特征的弱模拟信号直接转变成数字量检测，提高了检测的准确率及抗干扰能力，并由步进电机控制胶囊掉头，有效地解决了胶囊体、帽的位置调整，分色调头排列，达到帽、体一致。

The results obtained from three different methods—the conventional numerical differentiation, the discrete wavelet transform method and the proposed continuous wavelet transform method were compared, it was demonstrated that the results are similar for signals without noise, but the signal-to-noise ratio of the result obtained by the CWT method is improved greatly comparing with the former two methods for noisy signals.
