基于TMS320F28335的莫尔斯报训练器设计

Design of Morse Code Training Equipment Based on TMS320F28335

针对当前莫尔斯报训练器存在的使用不便、适应性差、识别率和识别速度低等问题，设计了一种基于TMS320F28335DSP的莫尔斯报训练器，具有发报、收报训练功能，识别结果可由液晶显示屏LCD12864实时显示或回送电脑，通过侧音产生电路产生反馈给操作者的监听音；由于采用动态自适应模糊聚类识别算法，提高了识别准确性和适应性，可以在5～100码／分的速度下正确识别莫尔斯码；应用结果表明，该训练器运行稳定可靠，识别速度快，具有一定的实用性和推广价值。

Aiming to solve the problem of inconvenience of using, poor adaptability, low recognition rate and low recognition speed, a new training equipment based on TMS320F28335 is designed to fulfill telegraph sending and receiving training, the identification result is dis- played by LCD or transmitted to PC in real--time. The circuit generates monitoring sound fed back to operator. The recognition algorithm is improved by using fuzzy clustering algorithm, the recognition accuracy and adaptability is improved. The training equipment can recognize Morse Code at a speed of 5 - 100 WPM. The application shows that the equipment is stable and reliable, recognition speed, has a certain practicality and promotional worthy.
