| 摘 要： | 针对煤矿井下设备通讯由于信号不稳,无法满足重要数据可靠传输,提出了一种汉明码结合二维奇偶校验码的数据传输算法。该算法不仅利用汉明码能够纠正传输过程中的一个错误,发现2个错误,而且结合二维奇偶校验码将传输过程中的2个错误纠正过来。该算法具有较强的抗突发干扰的能力,提高了数据传输的可靠性。

| Abstract: | Due to coal mine equipment transmission is unreliable;some important data can't be corrected transmitted.An error corrected algorithm is proposed,and the algorithm uses hamming code and parity check code.This algorithm not only corrects one mistake of transmission but also find two errors.Using parity check code can correct two errors of transmission data.This algorithm has stronger anti-disturbance and data transmission reliance. |
