A capsule endoscopic system is disclosed for receiving data from a capsule device and providing inductive power to the capsule device wirelessly, where the capsule endoscopic system incorporates a feature to automatically protect the capsule device and the docking device from damage if the capsule device is docked in a backward orientation. In one embodiment, the docking device comprises a current sense circuit to detect the current flowing through the primary coil or primary drive circuit. The occurrence of wrong orientation can be detected from the current. A detection/control circuit can be used to provide the needed control in order to prevent damage to the system. In another embodiment, a resonant circuit comprising a capacitor and the primary coil is used to provide the needed protection when the capsule device is docked with a wrong orientation.本發明揭露一種膠囊內視鏡系統,其用於從膠囊裝置接收資料且以無線方式提供感應式電力予該膠囊裝置,其中,該膠囊內視鏡系統含括有若該膠囊裝置以背向方向停駐時,則自動保護該膠囊裝置及停駐裝置免於損壞的技術特徵。在一實施例中,該停駐裝置係包括:電流感應電路,以偵測流過初級驅動電路或初級線圈的電流。錯誤方向的發生可從電流偵測。可使用偵測/控制電路,以提供為了免於該系統損壞所須的控制。在另一實施例中,包括電容器及初級線圈之諧振電路係用以在該膠囊裝置以錯誤方向停駐時,提供所須保護。110‧‧‧膠囊相機111‧‧‧次級線圈112a、112b‧‧‧濾波器115‧‧‧控制電路116‧‧‧LED(發光二極體)117‧‧‧電阻118‧‧‧電池120‧‧‧停駐系統121‧‧‧訊號源122‧‧‧初級線圈123、126‧‧‧放大器125‧‧‧光電二極體(PD)127‧‧‧資料/時脈復原模組
