Embodiments of the invention disclose a data transmission method and a related device. The method comprises the following steps: acquiring to-be-transmitted data for a high-speed magnetic levitation operation control system, carrying out fixed redundant coding on the to-be-transmitted data and generating first coded data corresponding to the to-be-transmitted data so as to achieve redundant codingof the data; then, coding the first coded data by using a feature code corresponding to the first coded data so as to generate second coded data corresponding to the to-be-transmitted data, thereby realizing unique coding of the data and further improving the security coding of the data; and then, calculating the check code of the to-be-transmitted data by utilizing the second coded data, whereinthe check code can be used for checking data in a message by the receiver, thereby ensuring the accuracy of the data in the transmission process. Moreover, the message adopted in the data transmission process carries the uncoded data to be transmitted, so the compressed transmission of the data is realized, and a bandwidth requirement on high-speed magnetic levitation 38G wireless communication is reduced.

    本申请实施例公开了一种数据传输方法和相关装置,获取针对高速磁浮运控系统的待传输数据,对所述待传输数据进行固定冗余编码,生成待传输数据对应的第一编码数据,实现了对于数据的冗余编码。然后,利用第一编码数据对应的特征码对第一编码数据进行编码,生成待传输数据对应的第二编码数据,实现了对于数据的唯一性编码,进一步提高了对于数据的安全编码。继而,利用第二编码数据,计算待传输数据的校验码,该校验码可以用于接收方对报文中的数据进行校验,保证了数据在传输过程中的准确性。此外,由于数据传输过程所采用的报文携带的是未编码的待传输数据,实现了对于数据的压缩传输,降低了对高速磁浮38G无线通信的带宽需求。
