The invention discloses a trackside electronic unit and a data sending method thereof, the trackside electronic unit comprises a first safety processing unit, a second safety processing unit, a first programmable logic device and a second programmable logic device, and the first safety processing unit and the second safety processing unit interact with respective system check words and system clocks. The first security processing unit generates an encryption field, the first security processing unit encrypts received message data by using the encryption field and then sends the encrypted message data to the first programmable logic device, and the second security processing unit generates key data by using the encryption field and sends the key data to the second programmable logic device; and the first programmable logic device sends the encrypted message data to the second programmable logic device, and the second programmable logic device decrypts the received encrypted message data by using the received key data to obtain decrypted message data and sends the decrypted message data to the transponder. According to the invention, the security and stability of data transmission are improved.

    一种轨旁电子单元及其数据发送方法,轨旁电子单元包含第一安全处理单元和第二安全处理单元,以及第一可编程逻辑器件和第二可编程逻辑器件,第一安全处理单元和第二安全处理单元交互各自的系统校核字和系统时钟,生成加密字段,第一安全处理单元利用加密字段对接收的报文数据进行加密处理后发送给第一可编程逻辑器件,第二安全处理单元利用加密字段生成密钥数据发送给第二可编程逻辑器件,第一可编程逻辑器件将加密后的报文数据发送给第二可编程逻辑器件,第二可编程逻辑器件利用接收的密钥数据对接收的加密后的报文数据进行解密,得到解密后的报文数据发送给应答器。本发明提高了数据发送的安全性和稳定性。
