| 摘 要： | 阐述了电力传输系统和信息传输系统在现代社会结构中的重要性及其相互关系，提出一种借助于电力传输线路传输无线电信号而服务于电力工程建设的移动通信方案，给出了以锁相环为基础的电路结构。该方案具有系统带通滤波器少，低通滤波器较多，电路结构简单，工作稳定，易于实现，经济性较好等优点。文中还对不同的技术方案进行了比较和讨论。实验表明，文中所提方案的抗干扰能力可与数字调制方式相比，能够满足实际工作需要。

| Abstract: | By use of power transmission lines a mobilecommunication scheme is proposed which can transmit radio signal and serve the electric power engineering and its circuit structure based on phase-lock loop is given. The proposedscheme possesses following merits: less band-pass filters, more low-pass filters, simple circuit structure, stable working and easy to implement, etc. Different schemes are compared and discussed. Experiment results show that the anti-interference capability of the proposed scheme which closes to that from digital modulation mode can meet the need in practice. |
