摘要： There are provided a method and an interface system for Bidirectional Synchronous Serial (BISS) protocol data decoding. The method includes: an MA drive module receiving an enable signal en and transmitting an MA clock signal to an SL receiving module, and then the SL receiving module detecting a trigger signal of SL; when a start bit of the SL is detected by the SL receiving module, the SL receiving module reading SL data; after the SL data is read, the SL receiving module transmitting a done signal to the MA drive module to stop operation of the MA drive module and transmitting a did signal to a CRC check module; and after the did signal is received by the CRC check module, the CRC check module performing CRC check on the SL data and outputting a correct position value after the check is completed.

摘要： A method of assisted mounting and error compensation for absolute grating ruler comprises: (1) when mounting a CMOS sensor and a grating ruler body, the CMOS sensor reads an upper and a lower sample windows, and due to an angle existing between the grating ruler body and the CMOS sensor, a difference exists between the numbers of the upper and lower sample windows, and by continually adjusting the grating ruler body or the CMOS sensor, the code reading difference minimized so that the angle is zeroed; (2) when mounting the grating ruler body and a mechanic housing, it is moved by a fixed displacement in a motion direction, and a grating encoding reading is recorded and an error compensating amount is obtained which serves as error compensation value in an actual motion to correct a cumulative error introduced by the angle between the grating ruler body and the motion direction.

摘要： The present invention is a method of assisted mounting and error compensation for absolute grating ruler. It comprises the following: (1) when mounting a CMOS sensor and a grating ruler body, the CMOS sensor reads an upper and a lower sample windows, and due to an angle existing between the grating ruler body and the CMOS sensor, a difference exists between the numbers of the upper and lower sample windows, and by continually adjusting the grating ruler body or the CMOS sensor, the code reading difference is made minimal so that the angle existing between the grating ruler body and the CMOS sensor is zeroed; (2) when mounting the grating ruler body and a mechanic housing, it is moved by a fixed displacement in a motion direction, and a grating encoding reading is recorded and an error compensating amount is obtained which serves as error compensation value in an actual motion to correct a cumulative error introduced by the angle between the grating ruler body and the motion direction. The invention may automatically calculate the deviation angles between the CMOS sensor and the grating ruler body and correct parallelism errors. Meanwhile, it also provides an error compensation in the case that the parallelism errors between the grating ruler body and the reference direction cannot be corrected.
摘要翻译：本发明是一种绝对光栅尺的辅助安装和误差补偿方法。它包括以下内容：（1）当安装CMOS传感器和光栅尺时，CMOS传感器读取上下样品窗口，并且由于光栅尺和CMOS传感器之间存在角度，存在差异在上下采样窗口的数量之间，并且通过连续调整光栅尺或CMOS传感器，代码读取差异最小，使得光栅尺体和CMOS传感器之间存在的角度归零; （2）当安装格栅尺和机械外壳时，沿运动方向移动一个固定位移，记录光栅编码读数，并获得误差补偿量，作为实际运动中的误差补偿值以校正由光栅尺体与运动方向之间的角度引入的累积误差。本发明可以自动计算CMOS传感器和光栅尺体之间的偏差角度并纠正并行误差。同时，在光栅尺和基准方向之间的平行度误差不能被校正的情况下，还提供误差补偿。
