计算机并口在电台同步数据传输中的应用

电台同步数据传输系统终端在收发数据时一般为透明逐bit传输,计算机并行接口包括数据寄存器、状态寄存器和控制寄存器3个端口。针对这3个寄存器特点,采用计算机并行接口数据寄存器发送数据,状态寄存器接收数据和同步时钟,控制寄存器控制电台PTT。同时,采用插入特殊码组实现群同步的方法,实现了电台同步数据传输系统终端的设计,完成了数据终端与电台之间的数据双向传输,并给出了实现方案和程序设计。

Applications of Computer Parallel Interface in the Synchronous Data Transmission System of Transceiver

The synchronous data transmission system terminal of a transceiver always transmits bit by bit transparently when receiving and transmitting data. A computer parallel interface includes three ports respectively for a data register, a state register and a control register. Taking the characteristics of the three registers into account, we use the data register of the parallel interface to transmit data, the state register to receive data and synchronize clock and the control register to control the transceiver's PTT in this paper. At the same time, using the idea of inserting special code groups to realize the group synchronization, we also actualize the design of the synchronous data transmission system terminal of a transceiver and realize the two-way data transmission between the data terminal and the transceiver, providing the implementation scheme and the program design.
