摘要
船用电缆通信的缺陷是电缆的成本高,设备的添加和减少都要对电缆进行变动。随着科技的发展,船舶设备的数量在不断增加,使得船舶电缆的铺设变得杂乱无章、维护成本大大增加。借鉴电力网络应用的电力线载波通信技术(PLC),则可以有效减少船用电缆的铺设量,降低船舶通信的成本。作者提出了一种成本低廉且实用的基于OFDM技术的船舶电力线载波通信模块的设计。文中介绍了OFDM船舶电力线载波通信系统的整体设计方案,并完成了系统外围电路各个模块的设计。
The defect of marine cable communication is high cost, and the cable will change when the devices are added or reduced. With the development of science and technology, the cable laying vessels become disorganized and costs of maintenance increased significantly. By learning from the application of technology of power line carrier communication to electricity network, the amount of marine cable laying and costs of ship communications can be reduced effectively. The author presents a design of ship power line carrier communication module based on OFDM, which is low-cost and practical. The paper describes the overall design of ship power line carrier communication system based on OFDM and completes the design of peripheral circuits of each module.
