The original Wiegand format had
1 parity bit,
8 bits of facility (or site) code (i.e. starting at the second bit in the sequence, and with a length of 8 bits),
16 bits of ID/user code (i.e. starting at the 10th bit with a length of 16 bits),
1 stop/parity bit for a total of 26 bits (see below).

The first parity bit (even) is calculated from the first 12 bits of the code and the trailing parity bit (odd) from the last 12 bits.
The original 26-bit wiegand format is depicted in the figure below.

楼主和我一样，金牌是灌水灌来的？

这话也是我想说的，哈哈
不过这个我还真会。。。。
