摘　　要：设计了一种跨网传输的串口通信软件,该软件采用数据收发双线程机制和数据队列线程间数据共享机制,设计了数据通信的数据帧类型校验、数据帧CRC校验和数据帧帧长校验等方法,保证数据高效性、安全性和完整性,通过速率测试和误码测试,证明该模型实现了可靠、安全和高效的串口通信,满足了在试验网和信息网之间实时数据通信的需要.This paper presents the design of a serial communication software cross network transmission, the software uses the data transceiver double thread mechanism and data queue data sharing mechanism between the threads, in order to ensure the data security efficiency and integrity, those methods are designed on the data communication, such as data frame type check, data frame CRC check and data frame length check. Through the test, the rate and bit error test, it proves that this model to realize serial communication is reliable, safe and efficient, to meet the future real-time data communication between the mission network and the information networks needs to be.
