载波通信在舰船电网中的应用研究

建立全舰各部门各舱室的通信网络是实现舰载设备远程自动控制的需要，也是舰员生活的需要。传统方法在改造旧舰或建造新舰时单独铺设通信电缆，费时费力，干扰正常工作，破坏水密性。考虑到舰船上分布最广泛的网络——照明配电网，如果可以利用电力载波技术将配电网复用通信网，则在节约了铺设和改造网络费用的同时满足了舰船内的通信需求。这里利用就网络总体设计和阻抗匹配两方面对电力载波通信技术应用于舰船电网进行研究分析，得出了舰船照明电缆输入阻抗与频率的关系，为实现舰船调制解调器与电力线信道的匹配提供了依据。

Application of Power Line Carrier Communication in Shipboard Electric Network

The establishment of communication network connected to every department and cabin in ship is the requirement of remote control and the demand of sailors＇ daily life. In traditional way, communication network is constructed independently, resulting in man-power and time waste, the disturbance of normal work, and the corruption of water tightness. In considering that the shipboard electric network is a wide network in ship, and if it can be used as a communication network by the power line carrier technology, the costs in laying and reforming network could be saved, and at the same time, communication demand inside ship be satisfied. Based on study and analysis of the transplant of power line carrier technology to shipboard electric network in network planning and resistance match, the relationship between the input impedance and frequency of shipboard lighting cable could be acquired, thus providing a basis for the impedance match of shipboard modulator/demodulator and power-line channel.
