【摘要】 双向工频通信技术(TWACS)是一种基于电力配电网络的新型通信技术,具有独特的调制解调机理。简单介绍了该技术的基本原理,采用相邻周期幅值作差的方法能够较好地消除共模干扰和缓变信号的干扰。并详细探讨了软件差错控制在该系统的应用。配合灵活的软件进行纠错编码的技术,大大提高了通信的安全性和可靠性。更多还原

【Abstract】 TWACS is a new valuable communication technology for distribution networks, which has special principle of modulation and demodulation. This paper restricts itself to the introduction of its basic principle, subtracting every adjacent period can rare eliminate common interfere and other interfere because of slowly variational signal, and it also discusses in detail the application of error controlling by software in TWACS. With error controlling by smart software, the security and reliability of the communication are enhanced much.更多还原
