大数据时代,以计算机技术和电子技术为核心的DAM数字调制技术为广播技术进步提供了良好的发展环境。中波广播发射机的调制方式实现了模拟方式向数字方式的转变,元件从电子管阶梯式发展到MOS场效应管,控制方式从纯机械方式变革为电子无触点数字逻辑和智能微处理器的控制方式,体现出DAM中波广播发射机技术的先进性与高效能。文章重点对我台10k W DAM中波发射机监控系统与功放模块常见故障进行了总结,作为交流和提高发射技术的借鉴。
In the era of big data, DAM digital modulation technology with computer technology and electronic technology at its core provides a good environment for the development of broadcast technology. The modulation mode of the medium-wave radio transmitter realizes the conversion of the analog mode to the digital mode. The components are evolved from the tube ladder to the MOS field-effect transistor. The control mode is changed from pure mechanical mode to electronic non-contact digital logic and intelligent microprocessor The control mode reflects the advanced and efficient DAM medium wave radio transmitter technology. The article focuses on my Taiwan 10k W DAM wave transmitter monitoring system and power amplifier module common faults were summarized as a reference for exchange and improve launch technology.
