| 摘 要： | 在利用低压电力线实现载波通信时,通信机与低压电力线信号耦合的关键问题是:既要求载波信号具有较高的传输效率;又要要求电力线上50 Hz的工频信号和各种噪声对载波通信系统的干扰最小;还要考虑载波通信系统的绝对安全.本系统采用了"电容隔离降压"、"电磁互感耦合"与"LC谐振式滤波"相结合的耦合技术,较好地解决了这一问题.

| Abstract: | In the process of applying low voltage power line to achieve carrier communication,the key point of coupling between communication device and transmission circuits is that power line carrier must be provided with higher transmission efficiency as well as the least interference to carrier communication system caused by 50 Hz alternating current and various electrical noise.In addition the safety of carrier communication system should be taken into account.The coupling technique including capacitor insulating... |
