摘要
供靶中,为了保证靶弹不飞出试验航区,需要安控地面站对靶弹实时控制,靶弹飞出安全区时需及时对其实施自毁,因此要求地面站必须具有指令实时上传功能。之前靶弹安控地面站受制于担当数据传输任务的数传电台半双工工作模式,安控地面站只工作于单一数据接收模式,因此要对其改造升级。利用AT89S52单片机对半双工数传电台的分时控制,实现了地面站实时接收数据和发送指令,安控地面站得以全双工模式工作,改进措施有效。
To avoid the target missile flying out of testing navigating zone, the safety control ground station must take real-time control to the target missile. When the target missile flying out of the safe area,it should be self-destructed in time. So the station must have the function of uploading instruction in real time. The traditional target missile safety control ground station is subject to the half- duplex working mode of data transfer radio which acting data transferring task, and the station only works in a single data reception mode,thus it should be transformed and upgraded. Based on the time-sharing control to the half-duplex data transfer radio of AT89S52 single chip microcomputer, the ground station realizes the functions of receiving data and sending instruction in real time, then the ~round station can work in full-dunlex working mode. The improvement measures are effective.
