摘要
针对实物电台电路复杂、价格高、用于训练会提高成本的问题,研制了一种机载超短波电台模拟训练系统。该系统采用51单片机作为核心控制芯片,通过控制芯片MAX7219,实现实际电台的频率及工作状态显示、存贮、调用及出错信息提示等功能,同时通过串口进行信息的发送。该电台模拟系统可以逼真地模拟电台的全部操作和显示功能,可用于电台通信的操作训练、院校教学演示等,模拟系统工作稳定可靠,具有较高的实用价值。
The physical radio has a complex circuits and is expensive, and the costs will be increased greatly if it is used for training. This paper developed an airborne FM radio simulator which uses 51 microcontroller as the core control chip. The actual radio frequency and status display, storage, call and an error message are achieved by controlling the chip MAX7219, and it also sends information through the serial port. The station simulator can simulate the operation and display functions of the physical radio realistically. The system is mainly used in the operation of radio communication training and teaching in school. The simulator is stable and reliable, which has a broad application prospects and a high practical value.
