一种数字放射摄影系统编码器校准装置
摘要：
本发明公开了一种数字放射摄影系统编码器校准装置，包括编码器、与所述编码器同轴的齿轮，其特征在于：还包括挡光片和槽式光电开关，所述挡光片安装在所述齿轮的边缘处，所述槽式光电开关安装在固定板上，所述挡光片与所述槽式光电开关的相对位置使所述挡光片在旋转时划过所述槽式光电开关的凹槽，还包括控制模块，所述控制模块分别与所述槽式光电开关、所述编码器相连，所述控制模块存储编码器相对原点脉冲数和编码器当前脉冲数，当所述控制模块收到所述槽式光电开关的信号后，使用所述编码器相对原点脉冲数对所述编码器当前脉冲数进行重置。
摘要（英）：

The invention discloses a coder calibrating device of a digital radiology photography system, comprising a coder and a gear which is coaxial with the coder. The coder calibrating device is characterized by also comprising a light shielding sheet, a groove type photoelectric switch and a control module, wherein the light shielding sheet is arranged on the edge of the gear; the groove type photoelectric switch is arranged on a fixed plate; a position of the light shielding sheet, which is opposite to the groove type photoelectric switch, enables the light shielding sheet to cross a groove of the groove type photoelectric switch when rotating; and the control module is respectively connected with the groove type photoelectric switch and the coder, stores the number of opposite original pointpulses of the coder and the number of current pulses of the coder, and resets the number of the current pulses of the coder by utilizing the number of the opposite original point pulses of the coder when receiving a signal of the groove type photoelectric switch.
